Fly in a rocket, that will be hundreds of years away.

And now, people can go to heaven, but they have to become reality. This is really a double happiness for the emperor, and he is in a good mood.

"Sun Qing will watch the ascension experiment of the Academy of Sciences from tomorrow to noon!" After Zhu Youxiao commended Sun Yuanhua, he smiled and sent out an invitation.

Sun Yuanhua hurriedly bowed down and said, "Weichen has received the news, and he is very shocked and curious. Tomorrow I will go to watch and open my eyes for a long time. ”

Zhu Youxiao smiled and agreed with Sun Yuanhua's statement that he had opened his eyes and had long insight.

It's just an enlarged version of the Kong Ming lantern, but if it is manned, it doesn't need to be too high, and ten meters and eight meters are enough for the ancients to be shocked.

Just wanted to have a sensational effect, so Zhu Youxiao asked the Academy of Sciences to demonstrate in public at the noon gate. True, it has already been successful in the Academy of Sciences, only minor improvements need to be made, and there is nothing to question about manned lift-offs.

In the eyes of the ancients, to be able to go to heaven is not to become an immortal and ascend in the daytime? But what Zhu Youxiao wants to tell them is that this is called science, not mythology.

I don't understand, it's okay, take your time, this is just the beginning.

Besides, if there is such a shocking and sensational event in my Apocalypse Dynasty, is it the same impact as Izumi Xiangrui?

"Hooray." Sun Yuanhua hesitated for a moment, but he couldn't help the doubts and curiosity in his heart, and said: "This chemical equation is very wonderful, but knowing it, not knowing why, it is difficult to understand the reason. ”

Zhu Youxiao smiled bitterly, it was really difficult to understand the reason.

What molecules, atoms, elements, what valency, what material composition, can be said but people can't see or touch, they can only memorize.

But Sun Yuanhua is right, with equations, many practical problems can be solved. For example, from the equation of gunpowder combustion, the optimal formula of gunpowder can be calculated.

"Now I can only memorize by rote and slowly study the truth." Zhu Youxiao knew that he was pulling out seedlings to help him improve, and faults were inevitable. But it is also a shortcut to deduce the process from the result and understand the principle.

Sun Yuanhua was a little disappointed, but he also remembered the advice of his teacher Xu Guangqi, and didn't dare to continue chasing, so he turned to say: "Weichen wants to study a more powerful gunpowder next, which is nitrocellulose." ”

The process and recipe of black powder have reached the end of their development, and it is difficult to increase their power. And according to the development process, it is nitrocellulose, then picric acid, nitroglycerin......

If nitrocellulose can replace black powder, it will be another cross-era progress.

You must know that nitrocellulose not only has a high explosive power and a better range, but also burns sufficiently, there is no residue, there is less smoke, it is known as smokeless gunpowder, and the damage to the barrel is also small.

It can be said that nitrocellulose basically compensated for all the shortcomings of black powder.

In fact, in Zhu Youxiao's view, the difficulty of making nitrocellulose and nitroglycerin is similar. Moreover, the weapons and equipment of black powder, Pingliao to destroy slaves, and even fight all over the world, are enough for the Ming army.

After pondering for a while, Zhu Youxiao decided to move the land step by step, and there must be a reason for such a development in history.

According to the technical conditions at that time, the manufacture of nitrocellulose was indeed relatively easy to succeed. The key is how to produce energy, and it's too easy to just make a small cloud of experiments.

"Sun Qing is a professor of the Academy of Sciences, so I can study and discuss with them more." Zhu Youxiao said: "I know that the Academy of Sciences can already produce sulfuric acid and nitric acid in the laboratory. ”

In ancient China, there was a method for making sulfuric acid, and the ancient method of producing sulfuric acid was to use green alum (ferrous sulfate) as raw material and calcined it in a distillation kettle. Sulfuric acid is mixed with saltpeter to nitrate, and nitric acid is produced.

Of course, before reading the book "Chemistry", the ancient people did not know what this game was and what it was used for.

"It is precisely when we see the results of the Academy of Sciences that we have the confidence to produce nitrocellulose." Sun Yuanhua bowed and replied, smiling, "There are a few students who are very talented in chemistry. ”

"With talent and diligence, there will be scientists like Shen Kuo and Guo Shoujing in my Ming Dynasty." Zhu Youxiao smiled and said: "Master Xu's achievements are not inferior to Shen and Guo, and Sun Qing will definitely be able to surpass Master Nai if he immerses himself in research." ”

"Wechen thanked the family teacher for long live the praise." Sun Yuanhua bowed down and said humbly: "Compared with the family teacher, Weichen is 108,000 miles away, and he has to work hard. ”

Zhu Youxiao smiled and said: "It is necessary to work hard, but Sun Qing does not have to be too humble. On the way to firearms, I see that you are already blue. Pingliao exterminated slaves, Sun Qing contributed a lot, and I remembered it. ”

"Long live the grace of Wechen Xie." Sun Yuanhua knew that it was time to retire, so he got up and thanked him.

The hall was quiet, and the emperor touched his chin and leaned in the imperial chair, his face seemed to be smiling, but he could see a little smugness.

The emperor is already at the top of the pyramid, this is fate. Regardless of his wisdom and foolishness, in the feudal era, he was heaven.

Yes, you don't need him to be smart, you don't need him to be diligent, as long as you can know people well, the world is stable.

And now, Zhu Youxiao feels that he has led Daming onto the right path of development. Even if he doesn't care anymore, there will be people who will continue to go down and continue to complete his vision.

Of course, there is still the possibility of overturning, and the only possibility is that he is gone.

Even if fate is unchangeable, in one year's time, I will complete the great cause of destroying slaves in Pingliao, right? In this regard, Zhu Youxiao is still quite confident.

Wang Tiqian entered the hall and interrupted the emperor's thoughts.

"Emperor, Yang Lian, the governor of Shanxi, and Fang Zhenru, the governor of Henan, have been summoned to meet you." Seeing the emperor's gaze, Wang Tiqian smiled and bowed down.

Zhu Youxiao nodded, sat up straight, and said in a deep voice: "Xuan!" ”

The major disasters of the Xiaoice River period were most severe in the north, and at the same time, Shaanxi, Shanxi, and Henan were the most serious.

Shaanxi was first appointed by Zuo Guangdou as the governor, and through the construction of water conservancy and the reduction of endowments for the people, the governance of the local area was quite effective. is now succeeded by Li Jingbai, who is also a good official.

And Yang Lian, the governor of Shanxi, and Fang Zhenru, the governor of Henan, have been out for several years, and they have also done a good job.

Although both of them have the label of the Donglin Party, they are fundamentally different from those officials who are full of benevolence and morality, but are actually greedy and shameless.

The main characteristic of the two is that they are honest and strict. If you are honest, you can be compassionate to the people, and if you are stern, you will not be afraid of the local vassal king.

can be compassionate to the people and alleviate the suffering of the people; It can strike at the feudal king and take back the fief according to the will of the imperial court. If he can do these two jobs well, Zhu Youxiao will be more satisfied.

Of course, the work of Qingtun is also indispensable to the strengths and selflessness of these two people. Ruthlessly cleaning up those landlords and gentry who encroached on Tuntian was also one of the important criteria for Zhu Youxiao's inspection officials.
