    With so many people and four young ladies, it was obvious that they couldn't hang out normally, so they had to go to the elephant shed together.  Li Jiyi thought that if he rushed Zheng back on the spot, the unknowing Zheng would be too submissive and might expose his flaws.  Rather than superfluous, it is better to be together first, find a suitable opportunity later, and explain to Mrs. Zheng alone before letting her go.  As expected, Liu Yaoniang has been secretly watching Zheng's every move, as if facing a formidable enemy.  There is no way, Zheng's appearance is extremely outstanding, much more beautiful than Liu Yaoniang.  She is an extremely beautiful woman and has a deep relationship with Liu Yaoniang¡¯s lover. How could she not be afraid of her?  "Moreover, Liu Yaoniang has always suspected the true relationship between Zheng and Li Jiyi, which makes it even more impossible to ignore Zheng.  The fourth child, Zhang Qing, was born into a commoner family, and the tutoring and knowledge he gained from his native family were very limited.  When Qin Cheng saw Zhang Qing frequently visiting Zheng, he couldn't help but cough slightly, took his arm, and reminded him in a low voice: "Fourth, don't look at anything inappropriate, understand?" Zhang Qing didn't covet Zheng's beauty.  He smiled and said: "Brother, how can you do that? I think that little lady is not like us from the Central Plains, but more like a Korean girl." He was also one of the lucky ones who made military exploits in Korea and was promoted to deputy captain.  one.  Qin Cheng had already noticed that although Zheng was extremely beautiful, she was not a Central Plains woman, but a Goryeo woman.  Originally, Qin Cheng only guessed Li Jiyi¡¯s true identity and did not dare to confirm it.  After meeting the extremely respectful Zheng family, Qin Cheng basically confirmed that Li Jiyi was the eldest son of the emperor.  With such a big bottom exposed, if you want to blame it, you can only blame the Bolinghou Mansion for its own shallowness.  Although the Marquis of Boling, Liu Mansion, and the Marquis of Guanxian County, Qin Mansion, are not close friends, their friendship is pretty good in terms of face.  Since Li Zhongyi became the ruling king, the old military ministers and honorary group promoted by Guo Wei and Chai Rong have slowly lost power.  The emperor and the ministers are the ancient and modern, the reason, it must be so!  The House of Liu, the Marquis of Boling, and the House of Qin, the Marquis of Guanxian County, were both run-down houses that had lost their power.  Both of these two princely houses have the title of marquis, but they can only scare the common people who don't know what they do, but they cannot scare the officials and dignitaries who really know what they do.  Originally, no one knew that Liu Yaoniang had an affair with the eldest son of the emperor.  However, things often go wrong in the hands of shallow women.  Once, several women who were good friends got together and everyone talked about their daughters¡¯ marriage.  Liu Yaoniang's own mother endured it again and again, but she couldn't bear it anymore and said abruptly: "Actually, the eldest son of the emperor likes our Yaoniang very much. You can't tell it." Best friends, or handkerchiefs here  This kind of creature, in addition to eating, playing, and shopping, will cheat teammates in most cases.  Can¡¯t tell it?  Within two days, this breaking news spread throughout the Quanjue family in the capital. ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Rumored by ten, and then a hundred, everyone knew that the eldest son of the emperor was interested in Liu Yaoniang.  In fact, when Liu Yaoniang met Li Jiyi by chance, she did not know his true identity.  However, the fire cannot be contained in the paper.  When Liu Yaoniang and Li Jiyi were shopping in Wazi, they were seen by Mrs. Bolinghou, Liu Yaoniang's grandmother.  Mrs. Bolinghou is a very high-ranking married woman. During every year and festival, she has to pass a sign into the palace to pay homage to the Empress Dowager.  Queen Mother Xue often had the virtuous concubines Tang Shuyi and Li Jiyi standing beside her. It was natural for Madam Bolinghou to get to know the eldest son of the emperor.  As soon as Mrs. Boling Hou came home and told the story, all the masters of the Liu family knew about it, including Liu Yaoniang's own mother.  After the news spread, Qin Cheng, as the only heir of the Qin family, it was impossible for him not to know.  However, Qin Cheng didn't know that Li Jiyi was the emperor's eldest son.  Nowadays, Liu Yaoniang treats Li Jiyi like a very affectionate little daughter-in-law. Qin Cheng is not an idiot, how can he not understand?  Liu Yaoniang was eyeing Mrs. Zheng, and Li Jiyi felt his head hurt.  To be honest, he also likes the cheerful Liu Yaoniang. ????????????????????????? But before these characters were even written, Liu Yaoniang regarded the Zheng family as her formidable enemy. What will she do in the future?  Zheng is already Li Jiyi¡¯s woman. Unless she dies, Li Jiyi will never let her go.  Hehe, Li Zhongyi is very domineering in this regard. As long as the woman he has fallen in love with, it is impossible for other men to touch her.  Now, Li Jiyi has grown up slowly, and has inherited the fine traditions of his father, and has an extraordinary desire to be exclusive with his women. ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????Brother, of course he couldn't just watch Lao Wu sit on the wax.  "Third sister, you can go play your own tricks, we have to go back to the martial arts hall to have something to do." As soon as Qin Cheng said these words, he immediately won Li Jiyi's great favor.  The feeling of being caught between two women was really unbearable. Qin Cheng's rescue was like pulling Li Jiyi out of the pit of fire.  Qin Juan was a little confused, but Liu Yaoniang knew in her heart that this was clearly Qin Cheng's excuse.  "However, Liu Yaoniang is an unmarried girl after all, so what position does she have to stop Li Jiyi from cheating?"  Just like that, Li Jiyi escaped smoothly.  However, what Li Jiyi never expected was that after everyone broke up, Liu Yaoniang sent people to keep an eye on Mrs. Zheng and followed Li Jiyi all the way to the fragrant nest where Li Jiyi used to hide his beauty.  At this time, Li Zhongyi was in the weapons prison, struggling with the issue of converter steelmaking.  Converter blowing method, although the output of steel has increased significantly.  But there are also two fatal problems. One is that steel with too high phosphorus content is very brittle, and the other is that there are many pores in the cast steel ingot.  Due to the fact that the craftsmen had no chemical knowledge at all, these two problems could only be solved by Li Zhongyi himself.  Although Li Zhongyi is not an expert in metallurgy, he is a famous expert in traditional Chinese medicine.  As we all know, Chinese medicine and chemistry are actually inseparable.  Based on Li Zhongyi¡¯s knowledge, he believes that after the phosphorus in the pig iron is oxidized by the air, it is reduced to phosphorus by the siliceous furnace lining and re-enters the molten steel. This is the fundamental factor that causes the steel to be brittle.  After some hard work, Li Zhongyi discovered that limestone can dephosphorize molten iron, but the original acidic silicate lining of the converter must be changed to an alkaline lining.  The new alkaline refractory bricks are made by mixing dolomite and tar that are burned into clinker at high temperatures.  Li Zhongyi conducted an experiment in the Ordnance Supervisory Steelmaking Workshop, lining it with alkaline refractory bricks, and adding limestone during the converter smelting process while blasting to make the slag highly alkaline. As a result, dephosphorized steel was produced.  The experiment was a great success and the alkaline converter steelmaking method was created.  It is no exaggeration to say that the success of this experiment is of epoch-making significance.  What Li Zhongyi didn¡¯t know was that Europe didn¡¯t develop a new steelmaking method like his until 1877.  A steelmaking plant cannot be built in Kaifeng.  Because Kaifeng has neither coke nor iron ore, the cost of large-scale production is too high.  Therefore, after Li Zhongyi became the ruling king, he sent more than a dozen prospecting teams to Dangtu County, Daye County and other places, and successively discovered the Gaocun Iron Mine, Gushan Iron Mine, Changlongshan Iron Mine, and Mushan Iron Mine.  Mine and Daye Super Mine.  However, although the iron mine was found, the steelmaking technology was not good enough, so the local area could only build an ironmaking plant.  Now that the new converter steelmaking method has been invented, Li Zhongyi sent a guidance group composed of steelmaking experts to the ironmaking plants near the mines to prepare for the construction of new converters for steelmaking.  As new steel-making furnaces were built in various places, the steel output of the Li Han Empire soared to fifty tons per day.  ?????????????????????????????:??????????????????: The daily output of a hundred jins of steel is only a few hundred kilograms. Both the quality of steel and the output are really far behind.  The steelmaking plants in Dangtu County and Daye County are very close to the Yangtze River.  The smelted steel first travels a short land route, is then transported onto a ship, and then flows along the Yangtze River into the sea. From the Yellow River into the river, it can directly reach the gun-making workshop and cannon-making workshop of the Kaifeng Ordnance Supervision.  As we all know, the transportation cost of water transportation and sea transportation is the lowest.  Under normal circumstances, the cost is at least thirty times lower than that of land transportation.  At the same time, the craftsmen in the cannon making workshop also made major breakthroughs.  Li Zhongyi looked at the ten 12-pound steel cannons cast in front of him using the lost-wax investment casting method, and couldn't help feeling ecstatic in his heart.  The biggest disadvantage of the traditional clay mold casting method is that after the soil is heated, bubbles are easily generated in the inner bore of the barrel, resulting in a very high scrap rate.  The lost wax method uses wax to make a model of the artillery. The inside and outside are filled and reinforced with lime clay and charcoal mud. After drying and heating, the wax liquid flows out, blocking the wax discharge port, and then injecting metal solution.  After cooling, remove the filling mud and you will get a complete cannon that is the same as the wax model.  This kind of steel cannon cast by the lost wax method uses a mixed type of fire-resistant and high-temperature resistant materials. It not only has a longer barrel, a longer range, fewer bubbles, but also has a lifespan far longer than that of a bronze cannon.  Every major advancement in science and technology makes Li Zhongyi sincerely happy.  In the past, under the overall social atmosphere that valued Confucianism and suppressed business and despised workers, even if craftsmen made scientific and technological progress, many world-leading technologies were lost due to the lack of attention by the bureaucracy.??lost.  Li Zhongyi attaches great importance to technological progress and the cultivation of craftsmen. For every technological advancement, he will order people to record the methods in detail, and then spread and study them widely within various scientific research groups.  According to Li Zhongyi¡¯s plan, in the near future, he will establish a brand new school, the Imperial University of Science and Technology.  By then, the Empire¡¯s weapons inspections, gun workshops, steel mills, shipyards and other institutions will all be run by graduates from the University of Science and Technology.  It has always been Li Zhongyi¡¯s employment principle to let professional talents do professional things.  With the continuous deepening of institutional reform, the backward situation in which everything is inferior and only Confucianism is high will be gone forever.  In Li Zhongyi¡¯s eyes, since Emperor Wu of the Han Dynasty only respected Confucianism, most of the bureaucrats trained in the past dynasties were hypocrites.  As the saying goes, serving as an official will benefit one party.  In fact, if you scrape the land and scrape the sky three feet high, and serve as a relatively clean magistrate for three years, you can get at least 100,000 yuan. What about corrupt officials?  Anything that goes against basic human nature will not last long.
