The first day of February is auspicious and it is suitable to travel far.
This is a good day calculated by Yuan Chenggang, the former volcanic commander of the new Astronomical Academy. Yuan Chenggang, who Wang Kuang called a great stickman, has been very conscientious since he took office. He has attracted a number of talents to the Astronomical Academy and used his influence to fool many ignorant people into choosing to study at the Astronomical Academy. There is an extra large clairvoyant in the courtyard that is two or three times larger than the ordinary clairvoyant. It is said that you can see Chang'e dancing on the moon goddess1,. .
This huge telescope took Chang'an Lifang more than a year to complete after tens of thousands of failures. It can be said that the money invested by the imperial government in this telescope far exceeded 100,000 yuan. Go down. This does not include the many manpower invested in this. The most famous jade craftsmen in Chang'an were recruited here just to polish several lenses of Qianli Mu to a very perfect level, although it is far from perfect. It achieves the ideal effect of an entry-level astronomical telescope in Wang Kuang's mind, but in this era, it is already a great invention comparable to Cai Lun's papermaking in the eyes of the big guys.
When Senmile was around, people looked very big, but in reality they were only three inches in diameter. After Wang Kuang's calculations, it can only achieve the effect of magnification of more than 20 times. Measuring the magnification is very simple. As long as you know the focal length and the distance of each lens, you can draw it on paper and use simple geometric algorithms. This is not easy. It required a lot of advanced knowledge, so it was quickly mastered by the new masters from the Astronomical Academy, and they also mastered the working principle of the telescope. This gave Wang Kuang a small sense of accomplishment, after all, he had mastered the principle of the telescope. After learning and making methods, there is hope that bigger and better ones will appear in the future. Over time, people's ability to explore unknown fields will gradually be strengthened, and inspired by new discoveries, many people will step into this field one after another. Astronomy is almost the driving force for the development of modern physics.
Of course, the glass piece that Qianlimu failed more than ten thousand times has not been lost, which is a good thing. It was difficult to see clearly, but it was possible to focus light. Wang Kuang asked the craftsmen to wrap the edges with copper. A handle is inlaid, allowing Qin Qiong to carry a thousand pieces, and these thousand pieces are worth mentioning. Taking fire as a unit, each fire soldier is equipped with one. If it is released under the sun, it can easily ignite a pile of dead grass. What is the most popular at this time in Hebei? Naturally, it is just dry grass and dry wood.
Qin Qiong took away not only lenses, but also tens of thousands of toothed steel insoles. The structure of the insoles was very simple, a steel plate with one-minute-long sharp teeth cut out on all four sides. Then bend it downward. When using it, soldiers only need to tie it to the sole of their shoes, and they can walk and run very easily on the ice. They can even stand and walk easily on sloping ice slopes1,. This had already been tested on the school field on the day it was made. With this thing that could walk on ice, Old Man Qin laughed happily and said that if he failed to win this battle, he would not come back. Just freeze to death outside.
Xu Guoxu also took away tens of thousands of them. He did not use them for himself, but wanted to bring them to the navy officers and soldiers of Dongzhi. As for the lenses used to ignite the fire, he did not need to bring them, because all the soldiers from Jian'an in the Jianzhou Navy had mastered the art of using local materials and ice to make such mirrors. A soldier could make two or three good mirrors in just a cup of tea. It's useful, so there's no need to carry an extra thing with you that would be cumbersome.
When Xu Guoxu came to Wang Kuang with a frown on his face, he said that no matter how overtime the craftsmen of the inner government and the equipment supervisor had worked overtime in the past few months, they only got one thousand catties of powder for making ice. How could this one thousand catties be enough? At least a few kilograms should be used at one time, right? A thousand kilograms can only be used dozens of times, and it will float on the vast ocean for several years. What should we do? Wang Kuang laughed loudly after hearing this: "You bastard, if you put the water-soluble thing in the sun to dry it out, it can be used again and again. As long as you keep it properly, this thing can be used again." It's not like it's used once and then lost. This thousand kilograms can be divided into dozens of kilograms by a building ship, which is enough for everyone."
Only then did Xu Guoxu feel happy. When summer arrived on the ocean, the sun was blazing and it was so hot. If this thing could be reused, there would be no need to worry. Even if it weighs tens of kilograms, it would not guarantee that everyone on the ship would be able to eat ice cold. Yes, but at least when it is not in use, you can make some ice and store it in the ice cellar in the bottom cabin. The less it makes, the more it will be. When you need a lot of it, can't you take it out and use it?
No one in Qin Qiong's group saw him off, because the conquest of Goguryeo could not start as soon as he arrived, and it would take some time to prepare, so his whereabouts must be kept secret and cannot be detected by Goguryeo spies. Spy warfare, but from then on It began to exist in the Shang Dynasty. The term spy was first proposed by Taigong.
Xu Guoxu and his party numbered in the thousands. They were all strong men who were proficient in water skills selected in Chang'an. They took their wives and many craftsmen with them. They even assigned each boat with a sword and pen official to use it. To record the big and small things that happened every day during the ship's journey, Dongzhi's side was mainly composed of soldiers and sailors, who were called "Jianzhou Navy"?I have been out practicing for more than half a year, and I am just waiting to set sail and go to sea.
Starting from Zhuque Gate, we headed south along Zhuque Street. Both sides of the entire Zhuque Street were crowded with people. Everyone came to see this extraordinary trip to the sea. In the past, only private businessmen themselves came. The two ships went out to sea, but now, the court came forward and it was the big ship that could carry three thousand people. How big is the building ship? At least 90% of the people in Chang'an City have never been seen, but think about it, three thousand people have to live on that ship for several years, eating, drinking and sleeping on it. How can it be as tall as the gatehouse of Mingde Gate? This is the maximum height they can imagine. At this time, the location of the Big and Small Wild Goose Pagodas is still empty, with no tall towers standing. In the eyes of the people of Chang'an, Mingde Tower is already considered the tallest building in the Tang Dynasty.
¡° Living on such a tall ship should be no different from living on land, right? What strong wind in the world can blow it down? People who have never experienced a typhoon have never thought about the dangers and difficulties that Xu Guoxu may face on his trip. In their view, this trip is not only about exploring the huge continent with almost no people in the east that Jian'an Marquis said. Otherwise, it has no practical purpose. But they also understood that this time was also a time to demonstrate the power of the Tang Dynasty. After going to sea this time, when merchants go to sea in the future, the pirates will have to weigh whether they can withstand the Tang Dynasty's return ten times and a hundred times. its revenge.
It is precisely because most people are unaware of the many unknown risks that the soldiers will face. Therefore, the fathers, brothers, and other family members of those who are traveling are looking around the crowd with joy. They are thinking for their brothers and themselves. I am extremely proud that my children can have such an opportunity, and the slight sorrow of separation has long been washed away. Isn't it just a few years of separation? Youdao is a good man with ambitions in all directions. Many people spend their whole lives traveling around. What does a few years mean?
It's not without sadness. When the loving mother handed over the robe that she had stayed up late at night to sew densely for several years since she learned that her children were going to travel far away, there were clearly tears in the corners of her eyes, but she felt sad. You have to force yourself to laugh and worry that your children won¡¯t be able to bear it.
"The thread in the hands of a loving mother, the clothes on the wanderer's body, are tightly sewed before leaving, and I am afraid that I will return later" Wang Kuang silently recited this familiar poem that all three-year-old children in later generations had memorized. For a moment, he felt sad in his heart, and the two lines were clear. Tears rolled down. At this moment, he remembered the scene when he saw Hiramorita for the first time. A scholar respectfully put on the robe sewn by his old mother, preparing to use what he thought was the highest etiquette. Apprenticeship, he also recalled the scene when his sister was sewing shoes and quilted jacket for him under the dim oil lamp when he was a child. Because his eyes were overused when he was young, when Wang Kuang passed by, his eyesight was no longer good. Now, I don¡¯t know what¡¯s going on?
"Erlang, why are you crying? It's not about life and death." Xu Guoxu pursed his lips, turned away, and shed tears himself. He and Wang Kuang were both marching in the team, and they both saw the same scene. Where was the difference? Do you know what Wang Kuang is thinking? Similarly, he also thought of his father and mother who must be watching him in the sky at this time.
"Remember, no matter what happens, people come first." Wang Kuang tightened his belt, exhaled a long breath, and told Miao Jiu and Hu Hanshan: "The same is true for you two, what are you doing? Nothing is more important than your own life. Do you remember the words of a thousand exhortations?"
"Remember, don't touch brightly colored things, and stay away from beautiful snakes, insects, and frogs." Miao Jiu and Hu Hanshan replied in unison, "Also, whenever you go to a place, if there is a shortage of food, you must first check the local animals. You have to choose what to eat and what not to eat. As long as the ship can accommodate it, I would rather bring back more seeds and seedlings than bring back jewelry"
Wang Kuang nodded: "Just remember, that jewelry is a dead object, and no one will take it away if it is left there. Since it was discovered by my people from the Tang Dynasty, it is my property of the Tang Dynasty. No one can take it away. Seedling seeds You can see how precious it is from the fact that the Parthians were willing to spend a lot of money to get it this time. A new crop may be able to change the lives of people all over the world. If you can¡¯t get the jewelry back this time, you can get it next time. Take it, but the seedlings need to be domesticated and cultivated over time. If we take it back a year earlier, we can gain one year. These are one of the foundations for our future development in the Tang Dynasty. Can the saint's ambition be realized? , it depends on how many thousands of you there are.¡±
"Okay, okay, Erlang, when did you become such a mother-in-law? Are you still worried that these little bastards dare to disobey? Among the thousands of people, at least 30% are from Jianzhou. With them, , Who dares to act recklessly?" Xu Guoxu saw that he was out of Mingde Gate, then he stepped on the horse and waved the envoy in his hand: "My sons, please hurry up, get to Dongzhi early, and go to the sea early to see the infinite scenery. Go!" Then he galloped on his horse without looking back, and only said a few words to Wang Kuang from a distance:??
"Erlang, those children are begging you. If I find that someone is missing a hair after I come back, I will come to you to settle the account"
