Chapter 65 Li Yunxing’s studies
Li Yunxing was very depressed.
With Li Yunxing's ability, he went to the Imperial Academy by paying tribute. Somewhat difficult. It is almost impossible to get ahead in the Imperial College. But in any case, Li Yunxing was also a scholar, with very solid basic skills, and he was from an official family, so he was much better than these craftsman disciples in terms of background.
Within a few days, Li Yunxing became a student leader in these engineering colleges.
Yang Zhen likes him, and Ge Tiangong also likes him. I am willing to call him for anything.
This is generally why people in this era worship knowledge. After all, even though these craftsman disciples have read some books and can write and do calculations, they are only good at writing and calculation. They themselves do not consider themselves to be scholars.
But Li Yunxing is different. He is a serious scholar. In the School of Engineering and Science it is dimensionality reduction that strikes. Moreover, Li Yunxing has been studying for many years, and his basic learning ability is no problem.
Accept new knowledge quickly.
Stand out naturally.
But for Li Yunching, I don't know whether this is good or bad.
Because He Xi lacks manpower here. So I selected some people from among the students to start.
But here at He Xi, he experienced torture that he had never experienced before in his life. Although he feels that he is not a genius, he is not a fool either. Why did he know every word Teacher He said? But I don’t even know how to put it together.
What are explosive mechanics?
He Xi was actually helpless.
He was only well-known for explosive mechanics, but he had never met one.
During this period of time, he was doing two things.
The first is to purify gunpowder and increase the power of black-gunpowder. This is a state secret. Not to be leaked. After He Xi made the request to Zhu Yuanzhang, Zhu Yuanzhang immediately sent a large number of manpower. They all come from Jinyiwei. The leader was Liu Ben, a member of the Jinyi Guard Qianhu who had just been transferred from Hangzhou. He had met He Xi several times when he was in Hangzhou.
Zhu Yuanzhang promoted this person because, first, he had no internal relationship with Jinyiwei. He was promoted directly from the hidden pile. The second is that he has an old relationship with He Xi, and it can be regarded as He Xi's training of manpower.
In this regard, the people from Jinyiwei will fully assist.
He Xi doesn't need to worry too much.
So He Xi's mind was focused on other things. Such as explosive mechanics.
It sounds like he is being lofty. In fact, He Xi is studying how to use gunpowder with maximum efficiency. The last time I weighed 10,000 pounds, it seemed so enjoyable. But gunpowder also has a cost. If the amount of gunpowder is too large. If too little ore is mined, the cost may not be recovered.
He needed an efficient method of blasting. At the same time, this actually has military implications.
After all, during the Anti-Japanese War in later generations, explosives were packed. It is also a very important weapon. One of the five major skills of infantry is blasting.
Although the current black-gunpowder is not comparable to the gunpowder of later generations, even if He Xi adjusted the black-gunpowder ratio to the optimal state, it would still be inferior. But an army that can use gunpowder blasts in large quantities is much more powerful than an army with cold weapons.
But all of this is based on a method of using gunpowder.
It's just that if you can use gunpowder well. This is also a difficult problem.
At least He Xi doesn't know.
No one even knows. Even at the end of the Ming Dynasty, Li Zicheng caused a big mistake by blowing up the city. The city bombing was turned into a directional blast. Instead of blowing up the Kaifeng city wall, it blew up the rebels outside who were preparing to attack.
This is the lesson learned.
He Xi can only use one method, and that is experiment.
Determine different materials, in stones, in soil, in different stones, in different soils, using different methods, whether it is better to drill holes or make a horizontal groove. There are other geometric patterns, differences in depth and width, etc.
Of course, He Xi was just formulating experimental methods. Someone who really comes over and over again. is his student.
who is it?
It's Li Yunxing.
So a month ago, Li Yunxing, who was still studying in the Fu School, was now under the scorching sun, leading the craftsmen to blow up the mountain over and over again. He must follow He Xi's regulations and record all explosion points in person before exploding them. Then after the explosion, you have to verify the effect yourself.
etc.
This is not an easy thing to do.
Especially there are some dangers.
After all, craftsmen had never used gunpowder like this before. I have encountered various problems like this. For example, a craftsman was hit hard by a stone from Feilai. Fortunately, his head was not hit, but his bones and tendons were broken. Right in front of Li Yunxing.
Li Yunxing is a young man from a wealthy family. He has never seen such a bloody scene. They were all frightened on the spot.
Without saying anything, he went to find his father. I begged my father not to do this.
But his father, Li Zhizhi, the prefect of Taiping, was overjoyed when he heard that Li Yunxing was now able to take charge of his own affairs under He Xi, and said: "Son, the hope of my Li family is pinned on you. There are some people and things that I have never dared to do before. Let me tell you, now that you have grown up, it is time to share my worries."
"Do you know? After the Hu Weiyong case, I have been on tenterhooks. I was worried that one day, the Jin Yiwei would break into our house and kill everyone in our house."
Li Yunxing said: "Why? Isn't this okay?"
Li Zhizhi said: "Because Hu Weiyong is a person of Han Guogong. I am also a person of Han Guogong. Hu Weiyong's downfall is clearly because His Majesty already had opinions on Han Guogong. And Han Guogong is also old. Said He may leave at any time, but once Han Guo Gong leaves, the eldest son will never take over Han Guo Gong's stall."
"What will we do then?"
"It's pitiful that you are favored by Consort He. No matter what Consort He wants you to do today, even if he wants you to die, you must go. Because you are by Consort He's side, my family can change from being under the sect of Han Guogong to If you have any consort, you will be able to turn the danger around."
Therefore, Li Yunxing could only go back in despair and continue working.
However, you will get used to it as time goes by.
It's hard to avoid casualties in this kind of thing. Don't say anything else, just don't fry it, or delay it. This is a common thing. After all, the fuse got wet or was blown off. This is very common. After a problem occurs, it is natural to have the craftsman take a look.
Most of the time, it comes back full and complete.
But of course there will be times when one's body will be shattered into pieces.
When encountering such a thing, all He Xi can do is to provide generous compensation and sum up experience. After all, even if there is such a mining operation in later generations, there is no guarantee that no one will be killed. Not to mention exploring from scratch.
Later Li Yunxing got used to it.
He fell asleep listening to the sound of cannons every day. There are dozens of boxes for recording various data. The effects of various blasting techniques, etc. I don’t know how many records were recorded.
Li Yunxing also unknowingly became obsessed with the things at hand.
I seem to feel the difference between explosions, intuitively feel the relationship between various explosions, and seem to understand what the art of explosion is.
------
Not to mention Li Yunxing’s homework. Just say He Xi.
In fact, He Xi's job is not easy at all.
Although basic courses, such as mathematics, physics, chemistry and other basics, He Xi has already mastered them. Many of them are transcribed on the computer. However, He Xi did not announce it to the world, and even taught it in Mingjiantang. It is just placed in the library of Mingjiantang, and those who are willing can read it.
Mathematics is the only subject that Mingjiantang must learn.
He Xi originally thought it would cause an uproar. But he overestimated himself.
Because many great Confucians can explain the nature of heaven and earth. Such as Zhu Xi. Many people know that Zhu Xi was a great Confucian, but few people know that Zhu Xi was considered a master of natural science at that time. The earth was round and the planets worked. Four seasons, sea and land subsidence. His views on various aspects such as ocean tides are not much different from those of later generations. Of course, there are some that conflict with science. But in Zhu Xi's time, it was already quite good.
Therefore, He Xi came up with a set of natural science explanations. In fact, it caused much less sensation than when He Xi took out the study of history and put it on the opposite side of Confucian classics.
Because the former is the fundamental dispute. The latter is just a fight between branches and vines. Not even taken seriously.
