    Chang'an, at the residence of the Duke of Song Dynasty.

    Du Rui and Baochai sat opposite each other. Baochai's face was full of worry at the moment. He wanted to speak several times, but he was a little timid and could only cry secretly.

    When Du Rui saw this, he sighed and said, "Okay! Baochai! The situation is not as difficult as you think!"

    Seeing Du Rui speak up, Baochai said anxiously: "Husband! Why are you so unconcerned? Isn't Xuewu your son? Now that the situation in Australia is extremely corrupt, do you still want to hide it from me?"

    Everything that happened on the Australian Road has long been spread to Du Rui's ears with the caravans, but Du Rui doesn't know yet that the native rebellion has been suppressed and order has been restored on the Australian Road.

    Baochai had strongly opposed Du Rui's decision to keep Du Xuewu in Australia. When he first heard about the rebellion in Australia, how could Baochai not worry about Du Xuewu's safety? He was worried for several days and had trouble sleeping and eating.

    Du Rui also smiled bitterly. Two days ago, Wei Shuo sent people to report that there was a rebellion in Australia. Baochai happened to hear it. In the past two days, he urged Du Rui to send people to Australia to bring Du Xuewu back.

    "Zhongfu is my son. He was born in the Duke's Mansion. He has enjoyed all the wealth and wealth. Now he has to fulfill his responsibilities for the Tang Dynasty. This is something he cannot avoid. I think Zhongfu  He must not be willing to be a deserter. You don¡¯t need to talk about Baochai sending people to Australia! If he is my son, Du Chengming, he must have this awareness! "

    Baochai heard this and said anxiously: "As Du Rui's son, you have to be in danger all the time, husband! Don't you think about Princess Isabella? She will learn martial arts as a son! What if?  If there is an accident, how will you let her survive?"

    Father and son are connected, how can Du Rui not be worried about Du Xuewu's safety? But if he calls Du Xuewu back at this time and lets Di Renjie face the massive rebellion of the natives alone, how can he be worthy of Di Renjie's deceased parents?

    "Baochai! There is no need to say anything more about this matter!" Du Rui's tone became a little stern and said, "If Zhongfu can't even handle this matter, he is not worthy of being my son!"

    Baochai became anxious when he heard this and said: "I know that there is no benefit to being Du Rui's son, okay! Since you don't send anyone, I will go to Quanzhou myself and send someone to Australia to learn martial arts."  return!"

    Baochai said and was about to get up and go out. When Du Rui saw him, he wanted to get angry, but he couldn't bear it and hurriedly comforted him: "Baochai! You~~~~~~~~~Oh! You're going now  So what, it will take at least a month to go from Chang'an to Quanzhou, and it will take another few months to cross the ocean to Australia Road. Maybe by the time you get to Australia Road, the rebellion will have subsided!"

    Baochai was born with a fierce temper. Although he was usually very submissive to Du Rui, when his temper got worse, even Du Rui became frightened. He raised his eyebrows and opened his almond-shaped eyes and said: "Husband, please don't hide your identity from me."  , The Australian natives are extremely vicious and barbaric. When they rebelled, you had to go there in person before they could be put down. They can only learn martial arts as a young man, and Huaiying has no military knowledge, how could they be suppressed so easily!"

    Seeing this, Du Rui had no choice but to tell the truth, saying: "When my husband left, he left more than ten thousand cavalry for Huaiying on the Australian Road. They were all elites, and there were also tens of thousands of cavalry that Feng Yi paid for  A war horse, the heroic cavalry general Yang Dao has been serving under me all year round. Among the young generals of the Tang Dynasty, he is also the best. Even if he cannot suppress the rebellion, he can protect himself. Moreover, Huaiying has not sent anyone to Chang'an until now.  Call for help, the situation must be under control, you are dying here, so what can you do, it is better to wait for news!"

    When Baochai heard this, she was immediately determined. Although she was not familiar with military affairs, she had Du Rui, the military god of the Tang Dynasty, in her family, and she also knew how powerful the Tang army's cavalry was. Although the Australian natives were extremely vicious and barbaric, they were not cavalrymen.  opponent.

    "In that case, why didn't you tell me earlier?"

    Hearing this, Du Rui was like a scolded child, smiling bitterly: "Baochai! You~~~~~~ you never allowed me to say it!"

    Hearing this, Baochai couldn't help but blush, and apologized: "It's all my fault, please punish me!"

    Du Rui was not willing to punish him. He just smiled bitterly. As he was talking, suddenly there was an earth-shattering sound outside, and even the ground began to tremble.

    Du Rui reacted and suddenly had a headache. He shook his head and said, "It must be Du Chengxue again!"

    Hearing this, Baochai also looked at Du Rui with sympathy. Obviously, this disciple of Du Rui is really a troublesome guy.

    Du Rui said to Baochai: "Baochai! Don't tell others about Australia Road, so as not to worry your family."

    Baochai nodded and said, "Don't worry, husband, I'll save you!"

    After Du Rui finished speaking, he came out.?, walked towards the front house. As soon as he walked out of the middle door, Du Rui saw a burst of black smoke. He was about to complain, but he heard a long-lost roar of machines. His face suddenly changed drastically, and he couldn't care less about his demeanor.  , quickly ran towards a room.

    Before he even ran to the house, he saw Du Chengxue running out like crazy. As he ran, he shouted loudly: "Teacher! Teacher! It's done! It's done! I'm finally a disciple!"

    Du Rui stepped forward, grabbed Du Chengxue, and asked excitedly: "But it's done?"

    Du Chengxue struggled for a while, and saw that the person who stopped him was Du Rui. Du Chengxue, who was usually just used to laughing and scolding, and was completely upright, actually looked bitter, knelt down in front of Du Rui, and burst into tears.

    "Teacher! I finally lived up to your expectations. I finally made the steam engine!"

    When Du Rui heard this, he left Du Chengxue aside and ran quickly to the door of the room. He was stunned for a moment. In front of him was this big thing that was blowing out thick black smoke, hot steam, and making a roaring sound. Although it was extremely simple, it was  Obviously, this thing is the steam engine that Du Rui has always dreamed about.

    It¡¯s really done!

    It¡¯s really done!

    Du Rui, who has always been very calm, suddenly felt the urge to cry at this moment. With this steam engine, steam ships can be built, and the Tang Dynasty's ability to conquer the seven seas will no longer be a fantasy.

    Steamships are no stranger to people of later generations. Steam engines are used as power and mechanical principles are used to propel ships. Historically, their emergence has brought about revolutionary changes in ship power, thus completing the revolution in ship power.  The driving force of ships changed from human and natural forces to mechanical force. The huge power provided by steam engines for ships made it possible to build larger and larger ships and carry more cargo.

    Historically, in the exploration of ship propulsion methods, in addition to tools such as oars, oars, and sails, paddle wheels have been invented in Egypt, Rome, and China to propel ships.  The Romans also used slaves and animal power to turn paddle wheels.  Before the 17th century, with the advent of the Age of Navigation, ship propulsion power methods had reached a period that required radical changes. At that time, the busy trade on the world's oceans needed to solve the problem of ship power.

    However, it was James Watt who really solved the problem of marine steam engines.  He invented the two-cylinder steam engine in 1765.  In 1768, he cooperated with Matthew Bolton, the boss of the Birmingham Turbine Factory in England, to develop a special-purpose steam engine for ship propulsion. This was the Bolton-Watt engine commonly used on early steam engines in the world. Ships used it.  Steam engines, steam engines and ships appeared.  Thus completing the third revolution in ship power.

    In the original history, the world¡¯s first steam engine ship was built by the American inventor Fulton.  In the spring of 1802, he built the first steam engine ship in France and anchored it on the Seine River, but a storm broke it.  Fulton did not stop there. He rebuilt a steam engine ship and named it "Clermont". It was 45.72 meters long and 9.14 meters wide. It was equipped with a steam engine.  In 1807, the "Clermont" made a successful trial voyage on the Hudson River in the United States. It sailed 91.4 kilometers at a speed of 6.4 kilometers per hour.  Since then, regular flights have been launched on the Hudson River in the United States, marking the official putting into use of steam engines and ships.

    The Piroscapi was the first ship to be entirely powered by steam. It was built by the Frenchman Marquis.  The ship has a single-cylinder steam engine that drives two paddle wheels on either side of the ship.  The first steam engine ship operating on the sea was the Phoenix steamship invented and built by American Robert Fulton, which sailed between New York and Philadelphia.

    In the 19th century, all the oceans were dominated by steam engines. Due to the emergence of steam engines, sailing ships eventually entered ship museums.

    Historically, China has also been deeply influenced by the West and has been committed to the development of steam engines and ships. The "Huanghu" is China's first steam engine ship. It was designed by Xu Shou and built by Anqing Manufacturing Bureau in 1865.  It is a wooden-hulled ship with a length of 55 feet, a displacement of 25 tons, a single-cylinder steam engine, and a speed of 25 miles per hour.  The "Yellow Hu" caused a sensation during its trial voyage, but compared with the Western world, China lags behind in this field for more than half a century.

    The core component of a steam engine ship is the steam engine. The steam engine is a reciprocating power machine that converts the energy of steam into mechanical work.  The emergence of the steam engine caused the Industrial Revolution in the 18th century.  Until the beginning of the 20th century, it remained the most important prime mover in the world, and later gradually gave way to internal combustion engines and steam turbines.

    A steam engine is a heat engine that converts kinetic energy into work.  Pumps, Locomotives and Steam Engines Ships were once powered by steam engines.  The steam engine played a fundamental role in the Industrial Revolution.

    A steam engine requires a boiler that boils water to produce high-pressure steam. This boiler can use wood, coal, oil, or natural gas.Gas or even garbage is used as a heat source, and the expansion of steam drives the piston to do work.  Historically, early steam engines used the vacuum created when steam condensed to do work, and later ones used the expansion of steam to do work.

    On the way to seek new power, mankind has made long-term explorations and attempts. The world's first steam engine was the steam ball invented by the ancient Greek mathematician Hero of Alexandria in the 1st century. It was the prototype of the steam engine.

    In 1679 AD, French physicist Denis Pabon created the first working model of a steam engine after observing steam escaping his pressure cooker.  At the same time, Samuel Moran also proposed the idea of ??a steam engine.

    Thomas Seville in 1698, Thomas Newcomen in 1712 and James Watt in 1769 built early industrial steam engines. They all made their own contributions to the development of steam engines.

    The famous Watt in history was not actually the inventor of the steam engine. Before him, there had been a steam engine, namely the Newcomen steam engine, but it consumed a lot of coal and had low efficiency.  Watt used scientific theory to gradually discover the problem with this steam engine.  From 1765 to 1790, he made a series of inventions, such as the separate condenser, the insulation layer outside the cylinder, the piston lubricated with oil, the planetary gear, the parallel motion linkage mechanism, the centrifugal governor, the throttle valve,  Pressure gauges, etc., increased the efficiency of the steam engine to more than three times that of the original Newcomen engine, and finally invented the steam engine in the modern sense.

    From the end of the 16th century to the late 17th century, the British mining industry, especially coal mines, had developed to a considerable scale. Manpower and animal power alone could no longer meet the requirements for removing underground water from mines, and there was abundant and cheap coal on site as fuel.  Realistic needs have prompted many people, such as Papin, Savery, and Newcomen in the UK, to devote themselves to the exploration and experiment of "lifting water with firepower".

    The original vacuum steam engines were used to pump water out of mines.  Newcomen's steam engine introduced steam into a cylinder and the valves were closed. Cold water was then poured into the cylinder, creating a vacuum as the steam condensed.  Air pressure on the other side of the piston pushes the piston.  In a mine, a rod is connected deep into the shaft to drive a pump.  The motion of the steam engine's piston is transmitted through this rod to the pump's piston to draw water out of the well.

    The first huge improvement was to separate the cylinder from the condensation cylinder by a valve.  Watt invented this improvement in Birmingham.  This improvement increased the efficiency of the steam engine.

    These early vacuum steam engines had limited efficiency, but they were safer because their pressures were lower and the machines contracted inward rather than exploding outward in the event of material damage.  Their efficiency is limited by external air pressure, cylinder deformation, efficiency of combustion and boiling, and condensation capacity.  The theoretical maximum efficiency is limited by the relatively low boiling temperature of water at ordinary atmospheric pressure.  The use of high-temperature and high-pressure steam greatly improves the efficiency of steam engines.  But this type of steam engine is much more dangerous than a vacuum steam engine.  Explosions of boilers and machinery caused many major accidents.  The safety valve brings a big improvement here, and the safety valve relieves the pressure when the pressure is too high.  But the real guarantee of safety can only rely on experience and safety rules in construction, operation and maintenance.

    The world's first practical steam water lifter made by Savery was awarded a British patent titled "Miner's Friend" in 1698.  He first filled an egg-shaped container with steam, then closed the steam inlet valve and sprayed cold water outside the container to condense the steam inside the container to form a vacuum.  Open the water inlet valve, and the water at the bottom of the mine will be sucked into the container through the water inlet pipe under the action of atmospheric pressure; close the water inlet valve, reopen the steam inlet valve, and rely on steam pressure to force the water in the container out through the drainage valve.  When the water in the container is drained and filled with steam, close the steam inlet valve and drain valve, and spray water again to condense the steam.  Repeat this cycle and use two egg-shaped containers to work alternately to achieve continuous drainage.

    Since the late 18th century, steam engines have been widely used not only in the mining industry, but also in smelting, textiles, machine manufacturing and other industries.  It increased Britain's textile output fivefold in more than 20 years, provided the market with a large number of consumer goods, accelerated the accumulation of funds, and put forward urgent requirements for the transportation industry.

    The steam engine is mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve steam distribution mechanism, speed regulating mechanism and flywheel.  The cylinder and base are the stationary parts.

    In a steam boiler, water boils into steam through a combustion process.  Steam is sent to the cylinder through pipes.  The valve controls the time when the steam reaches the cylinder, enters the slide valve chamber through the main steam valve and the throttle valve, and is controlled by the slide valve to alternately enter the left or right side of the cylinder to push the piston to move.  The steam pushes the piston in the cylinder to do work, and the cooled steam is introduced into the condenser through the pipe to condense into water again. This process is repeated as the steam engine moves.

    A general steam engine has three cylinders forming a group.  The steam engine directly converts the up and down motion of the piston into the rotation of the ship's shaft.  The new steam engine also contains a small turbine, and the steam coming out of the cylinder can also be used toThe waste heat turns this turbine to increase the efficiency of the entire drive.

    In terms of working principle, the steam engine invented by Du Chengxue is the reciprocating conduction type that appeared in Britain later. The high-pressure steam coming out of the boiler first pushes the first and smallest piston.  As this piston begins to retract some of the expanding vapor is driven into the second cylinder to push its piston, thus continuing to use the vapor expanding in the first cylinder.  The third cylinder uses steam expanded in the second cylinder.

    This kind of steam engine is especially important for ships at sea, because its steam can re-enter the boiler for heating after being continuously decompressed during the work process.  A ship at sea must conserve water because it may not be able to replenish it for a long time, whereas a steam engine on land can replenish water continuously.

    The emergence of the steam engine is absolutely epoch-making in history, because its emergence directly promoted the Industrial Revolution in the Western world. The Industrial Revolution first started in the United Kingdom in the 1760s and expanded significantly in the early 19th century.  Therefore, from a macro perspective, the second period of modern world history, that is, the steam age, began in the early 19th century and ended with the second industrial revolution in the 1870s.  During this period, the capitalist machine revolution began to appear, and the capitalist world system began to be initially established.  The invention and application of a new power machine, the steam engine, brought mankind into the steam age.

    The basic characteristics of the industrial revolution are that large-scale machine production replaces manual labor, factories replace manual workshops, the capitalist economy defeats the feudal economy, and human society begins to move from agricultural civilization to industrial civilization.  During this stage, liberal capitalism prevailed and economic crises began to emerge.

    Britain was the first to possess the political and economic prerequisites, so the Industrial Revolution first started in Britain and spread to European and American countries starting in the 19th century.  The economic crisis in 1825 first started in the United Kingdom, marking the unification of the British domestic market; the economic crisis in 1847 spread to the European continent, marking the unification of the European market; the first worldwide economic crisis in 1857 also marked the initial formation of the world capitalist market, and the entire world began to  On this basis, it is integrated.  Due to its advantages in technology, market, capital and other aspects, the UK ranks first in the world economic structure and has become the "world's factory".

    In the mid-18th century, more and more British goods were sold overseas, and the production in manual workshops was in short supply, so Hargreaves invented the Jenny machine.  The emergence of the Jenny machine increased textile efficiency by more than 40 times.  In 1771, Acollet set up the first water-powered spinning mill in Derby, and in 1782, Watt invented the linkage steam engine.  Modern large-scale industry was born, and a new form of organizational management was established, the capitalist large-scale factory system, so industrial capitalism began to dominate.

    When the capitalist system was established all over the world, the activities of the bourgeoisie to conquer the world also intensified unprecedentedly.  Due to the progress of the Industrial Revolution, colonial activities during this period developed from barbaric plunder to seizing raw material production areas and commodity markets. A large number of Asian and African countries and regions were forcibly incorporated into the capitalist system and became colonies and semi-colonies.  At this point, the capitalist system was established in the world.  Through the revolutionary reform movement and the conquest of colonies, the capitalist world system was initially formed.

    It can be said that the reason why Britain was able to become the powerful empire on which the sun never sets was entirely driven by the Industrial Revolution, and the outbreak of the Industrial Revolution was due to a small steam engine.

    Historically, there were people in China who were committed to the research and development of steam machinery. For example, the first steam car in history was born in China, or to be more precise, it was manufactured in Beijing.

    In 1672 AD, a Belgian missionary named Nan Huairen created a steam-powered mechanical device in Beijing and became the first four-wheeled steam vehicle.  At this time, Watt was not yet born, 115 years before he made the compound steam engine, 123 years before Symington applied steam engines to ships, 150 years before Stephenson used steam engines for trains, and 150 years before Stephenson used steam engines.  200 years before the automobile.

    Human beings will never stop in the pursuit of science. For example, power and energy, from the beginning of humans and animals, to steam, gasoline, and later solar energy, hydrogen, and nuclear energy, every step is the expansion of human tension.  result.

    ¡°For example, horses, from being unruly and unruly to being old and helpless, how long it took for humans to domesticate them before they can go far.  The use of steam is undoubtedly a revolution in power energy, freeing animals from huge labor loads.  The Englishman Watt invented the steam engine. Since 1765, mankind has entered the "steam engine age", and its mind has reached higher and farther.

    Originally, China wanted to be at the forefront of history. Unfortunately, Nan Huairen's invention had little repercussions at the time, and it remained dormant for many years.

    Who is Nan Huairen, and why can he trial-produce cars in China?

    This man was born in 1623 and was a Jesuit missionary. He arrived in Macau in 1658, which was the fifteenth year of Shunzhi in the Qing Dynasty.? He was sent to Shaanxi to preach, so he got a Chinese name, with the courtesy name Dunbo and Xunqing.  In the 17th year of Shunzhi, he was ordered to go to Beijing to assist Tang Ruowang in compiling the calendar. In the 8th year of Kangxi, he was the deputy supervisor of the Qintian Supervisor and presided over the compilation of the "Shi Xian Shu".  At this time, Nan Huairen asked Emperor Kangxi to design and supervise the construction of six large-scale observatory astronomical instruments, namely Tychonic classical instruments: equatorial theodolite, ecliptic theodolite, horizon theodolite, quadrant, chronometer and celestial instrument.  Completed in thirteen years.

    Liang Qichao, a reform figure, once commented on the role and influence of foreign missionaries in China: "There was a very important thing in the 17th century that should be devoted to Chinese academic history, and that was the influx of European astronomy and mathematics.  .¡±

    The car made by Nan Huairen was actually only two feet long and had four wheels. The important thing was the stove and boiler in the middle.  The copper boiler is like a modern kettle, with a flat bottom and a round top, with a jet spout on the top. After the kettle is heated, steam spurts out from the mouth, generating a lot of energy and hitting the turbine blades, like a water wheel that generates power.  , drives the rear wheels of the car and drives the car to move.  There is also a manual wheel on the front of the car to control the walking direction.  The steam emitted from the boiler can drive the car for more than 10 hours.

    Although crude and heavy, this car was definitely a great thing when it appeared at that time. However, Nan Huairen's purpose of making this car was just to please the emperor. It can really walk on its own without anyone pulling the horse. I don't know.  Emperor Kangxi was very happy to see it at that time. It is not known whether he took it out to play with when he was interested, but it is certain that Kangxi was very curious.

    Emperor Kangxi obviously failed to fully realize the significance of this car, or he did not issue an edict to make it a practical car.  However, this power, known as the Blanca impulse steam engine, had a profound impact on later generations.  By coincidence, Frenchman Cignaud spent six years making the world's first practical steam car in 1769.  The large boiler of this car has a large capacity of 50 liters. It is very strange. It has the same shape as Nan Huairen's steam engine, which shows Nan Huairen's sophisticated design.

    ?????????????????????????????????????????????????????????????????????????????????????????????????????????mbOUT out of his small brain capacity, Kangxi's big braid can dig out a little bit of thought and pay attention to it, maybe the history of Chinese civilization will be rewritten.

    Now Du Rui will no longer have such regrets. The first real steam engine in human history has been born in the Tang Dynasty. In the future, those Western barbarians can only look at the back of the Tang Dynasty and try to catch up.  .

    "Okay! Okay! Okay!"

    " Du Rui said three good words in succession. It can be said that Du Rui was never so happy about the birth of the original artillery and the current flintlock gun. That is because the significance of the emergence of this steam engine is so unusual.

    Du Chengxue seemed to be floating over with the wind under his feet at this moment. The steam engine was finally born in his hands. How many years have passed since he became a disciple of Du Rui and he began to study this thing. More than twenty years have passed.  Well, now that his research has finally yielded results, how can he not be happy?

    "Teacher! Is this steam engine okay?" Du Chengxue's words were filled with pride.

    On normal days, Du Rui would have to give him a blow to clear his mind, but now Du Rui can't care about anything. Facing the most awesome scientist in the Tang Dynasty, Du Rui wants to scold him, but he really can't.  Export, encourage, can only encourage, praise, can only praise.

    "Good! Good! Very good!"

    Du Rui was about to continue to praise him, but he turned around and saw that Du Chengxue was so beautiful that he was almost promoted to immortality. He suddenly changed his face and said: "It has taken so long and so much manpower and material resources. What can you be proud of?"  Yes, my junior fellow student Zhang Yanshuo has developed a flintlock gun a long time ago. If you can¡¯t fiddle with this steam engine anymore, what dignity do you have!¡±

    Du Chengxue was looking beautiful, but when he heard Du Rui say this, his face suddenly turned bitter and he said: "Teacher! This is not because the disciple is not dedicated, but~~~~~~~~"

    Du Rui laughed, took Du Chengxue's hand, and said: "What else is there, Chengxue! You have made a great contribution. Once this steam engine is born, the world will belong to the Tang Dynasty. No one can take it."  I won¡¯t leave. Thank you so much for being my teacher and treating everyone in the world!¡±

    As Du Rui said, he actually bowed deeply to Du Chengxue. Du Chengxue was startled, quickly moved away, knelt down on the ground, and said repeatedly: "The teacher is serious, but the disciple has achieved something, and it is also the result of the teacher's teaching. This  The principles of the steam engine were all taught by my mentor, and the disciple just built the steam engine according to the mentor's instructions. The disciple must not take credit!"

    Du Rui said with a smile: "No! I will teach you! You deserve it! You may not know how powerful this steam engine is at the beginning, okay! I will enter the palace right now and ask for credit for you!"

    " Du Rui doesn't want to stay for a moment now. Although this successfully running steam engine is still very crude, it doesn't matter. With this foundation,?With the outstanding talents of the Tang Dynasty, it is definitely not difficult to continue to make breakthroughs.

    Riding a horse on Suzaku Avenue is Du Rui's unique right. In the past, Du Rui acted low-key and rarely used it, but today he couldn't care less about anything.

    When the guard of Chengtianmen saw someone coming on horseback, he was about to stop him, but when he saw it was Du Rui, he not only did not stop him, but also sent someone to help clear the way. He was about to go up and ask what was important.  Du Rui flew past him like a gust of wind.

    It was not until they reached the corridor leading to the Daming Palace that Du Rui realized what he was doing. He got off his horse and someone from the palace immediately came up to him: "Master Du! I have something important to do when I enter the palace at this time!"

    Du Rui had no intention of chatting with him and said loudly: "Where is the Holy One? I have important matters to see you!"

    The palace man couldn't help but look a little embarrassed and said: "Master Du! Your Majesty has just taken a nap for lunch. Master Du, why don't you wait first? I'm so shocked that I can't bear it!"

    Du Rui was so excited that he had no time to wait. He said loudly: "Stop making noise! ??Where is the Holy One!? Bring me over quickly!"

    Du Rui rarely used his power to bully others, but today he couldn't care less about anything. With the emergence of steam engines, the Tang Dynasty would enter a whole new world. Du Rui wished that the court could tell the world now. As for the issue of leaking secrets, Du Rui  I have never thought that with Europa's current technological power, even if they wanted to steal the steam engine technology, they would not be able to develop it.

    The palace servant was startled by Du Rui and did not dare to say anything. He took Du Rui to the Chengqing Palace. He looked embarrassed and wanted to call the door, but he could not muster the courage. He was just a little palace servant. Where could he go?  Dare to take the risk of beheading.

    " Du Rui was impatient and didn't care about so much. He pushed the door open and walked in. When the palace man saw this, he was so frightened that he almost fell to the ground.

    Li Xian inside also heard the noise and stood up quickly. Just as he was about to scold him, he saw Du Rui coming and said hurriedly: "What's important, uncle?"

    When Du Rui saw that Li Xian was only wearing small clothes, he remembered that he was a little reckless, and said hurriedly: "The humble minister has lost his etiquette and disturbed the Holy One. Please forgive me!"

    Li Xian smiled and said: "What did my uncle say? My uncle has never been a humble person. There must be something important to do when I enter the palace today. I have rested enough. If my uncle has something to do, you might as well just say it!"

    Du Rui then said: "Your Majesty, you still remember the steam engine that Du Chengxue, the minister of the Ministry of Industry, has been studying!"

    Li Xian was stunned when he heard this. It took him a long time to think of it and said, "But what happened to that big iron frame? Could it be that Shilang Du caused some trouble again and let that big iron frame destroy my uncle's palace?"

    If Du Chengxue were here, he would probably be ashamed when he heard Li Xian's ridicule. Li Xian was not wrong. In the past year or so, Du Chengxue has caused a lot of troubles. It wasn't steam engine explosions or ruins.  The house disturbed the people, and the most serious one caused a fire, which almost burned Du Rui's Duke of Song Dynasty to rubble. Fortunately, there were no casualties in these accidents. Otherwise, no matter what Du Rui did,  Among them, Du Chengxue was probably enough to kill him eight times.

    "That's not true," Du Rui said hurriedly. Not only did he not cause any trouble this time, the steam engine also really succeeded!

    When Li Xian heard this, his eyes widened immediately. He had studied under Du Rui and was naturally exposed to the study of physics. He was also fascinated by the steam engine described by Du Rui. When he heard that the steam engine had been built, he immediately  Some can't react.

    "Uncle! Do you think Sir Du really developed that steam engine!?" Li Xian's voice trembled a little when he spoke.

    Du Rui nodded solemnly and said: "Wei Chen saw it with his own eyes, it's really done!"

    "Okay! Okay!" Li Xian said "good", pulled up Du Rui's sleeve and ran out.

    Du Rui hurriedly said: "Your Majesty! Are you going out like this?"

    "What's wrong?" Li Xian was surprised. When he saw Du Rui's eyes, he looked at himself, and then he realized what was going on. He laughed and slapped his forehead repeatedly, saying, "I'm actually impatient!"

    Li Xian changed his clothes, called the guards, and followed Du Rui to the Duke of Song's Mansion. When they arrived at Du Chengxue's so-called workshop, the roaring inside was still continuing, and Du Rui was completely relieved.

    Li Xian glanced at it, his face full of excitement, and said to Du Rui and Du Chengxue: "Okay! Okay! It's really good. Uncle, with this steam engine, will Datang be able to build what my uncle said in the future?"  Is that a ship or a train?"

    Du Rui nodded and said, "That's true!"

    With ships and trains, the connections between various parts of Datang will become extremely close in the future.The control of local areas will also become more powerful. Not to mention the local Taoism in the Tang Dynasty, even the overseas enclaves will be in the palm of your hand.

    Li Xian is a very smart person, and he immediately thought of the benefits, looked at Du Chengxue and said: "Du Aiqing! You have made this steam engine, and your contribution is to the country. I will reward you heavily!"

    Du Chengxue hurriedly said: "Your Majesty! This steam engine was all instructed by Weichen's mentor. Weichen just built it according to the instructions of his mentor. I really don't dare to take credit!"

    Li Xian laughed and said, "It doesn't have to be like this. The master wants rewards, and the disciples want rewards even more. Du Aiqing, with your skills, you can go straight to Lingyan Pavilion!"

    "ah!"

    When Du Chengxue heard this, he was immediately frightened and went straight to Lingyan Pavilion. What an honor it was. Since the founding of the Tang Dynasty, there were only a few people who were qualified to be listed in Lingyan Pavilion. However, there were countless people who were listed among them.  He is not a person who has made great contributions to the country.

    Although Du Chengxue is not keen on fame and fortune, he can't help but be tempted by this great honor.

    Li Xian continued: "Emperor Taizong ordered people to draw pictures and list them in Lingyan Pavilion for all generations to worship. I succeeded to the throne at a young age. Although I have not made any achievements for the country, I was fortunate to have the steam engine come into the world during the Hongwu Dynasty.  It's a blessing for the Tang Dynasty. If Du Aiqing's achievements are not qualified to be included in Lingyan Pavilion, then who else in this dynasty can have this qualification, uncle! Are you right!?"

    Du Rui was honored that his disciples could achieve such great achievements, and said: "The steam engine will bring the Tang Dynasty into a whole new world. This is indeed a great achievement, Your Majesty! Although Du Chengxue is a disciple of Weichen  Disciple, but no reward for such great achievements is too high!"

    Li Xian heard the words and said happily: "Okay! Uncle! When you go back, your cabinet will discuss it and make a list. There has been no addition to the Lingyan Pavilion for many years. This time, the great heroes of the Yonghui Dynasty will also be included in the list.  good?"

    Seeing that Li Xian had this idea, Du Rui nodded and said, "I obey the order!"

    Li Xian continued: "Not only the ministers of this dynasty, but also the famous ministers of the past dynasties, our Tang Dynasty has such a prosperous age, all because of the martial spirit, just like what my uncle said back then, Ran Min, Huo Qubing, this time I will return the favor."  We need to build another temple next to Lingyan Pavilion and the Martyrs' Shrine, and include all the military gods of China for thousands of years, so that they can be worshiped by all generations!"

    " Du Rui didn't expect Li Xian to mention this matter, but this is a good thing. If the descendants of Yan and Huang want to be at the top of the world forever, innovative spirit like Du Chengxue is indispensable, and martial spirit is indispensable.

    "After receiving the decree, I will prepare a list with the cabinet ministers when I get back, for the Holy One to make a decision!"

    Li Xian then watched the steam engine for a while, and then left happily. Du Rui had no time to idle. Although the steam engine was successful, there were more important things next. Although the steam engine was precious, it was still a dead thing.  , how to turn it into a living creature is the most important thing.
