As long as there is a direction, Song Yingxing is sure to study this mercury thunderate, for no other reason, there is no shortage of talents in Daming, or as long as it is a problem that can be solved by the number of people, it is not a problem in Daming.

It's just that whether it is Liu Hongji, who has not learned chemistry well, or Uncle Song, who swears, did not expect that this mercury thunder acid is not made by simple neutralization of nitric acid and mercury, in addition to these two necessary substances, another vital neutralizing agent is also needed.

What the two of them didn't expect was that in the end, mercury thunderate was made by an accident, but this is not surprising, whether in the East or the West, there are countless great inventions that have come out because of accidents.

"It's been a long time since I've been to the College of Engineering, and this Wang Ke is still the head of the College of Engineering! Let's go, Song Lao, go to the Institute of Engineering with this king to have a look. The development of mercury thunderate can't be done for a while, but it's not in a hurry, Liu Hongjian proposed.

Song Yingxing naturally will not defeat Liu Hongji's Yaxing, Liu Hongjian is the mountain chief, and Song Yingxing also has the name of the deputy mountain chief on his head, but both of them are a little unprofessional, and the School of Engineering has always been Xu Guangqi's son Xu Ji in Zhangluo.

It has been nearly a year since the opening of the School of Engineering in April last year, and the students of the School of Engineering have also been immersed in a good learning atmosphere.

The Faculty of Engineering implements a semi-closed system, and students are only allowed to go out for two hours every ten years, whether it is to go to the emerging market at the foot of Xishan Mountain to buy groceries or wander around to see girls, but they must go back within two hours anyway.

With the financial support of Xishan Shanghe, not only does the college not require students to pay tuition and miscellaneous fees, but even food, housing and even clothing are free, and Liu Hongji's big money is simply more than 500 years ahead of schedule to achieve compulsory education.

In Liu Hongchuan's understanding, the College of Engineering is different from the government schools in various parts of the Ming Dynasty, and the so-called Confucian students of the school will go to the Qinglou to hook up with little girls in addition to classes, which is called a merry and talented man.

But the School of Engineering is different, there is nothing to do here, what is needed is to drill into the palace of science and technology, to excavate, to explore, and to lay the foundation for the take-off of the Ming Dynasty.

This afternoon coincided with the closure of the School of Engineering, which was a good time to go out and have a good walk and see the world of flowers, but there were not many students moving around in the School of Engineering, and people came and went from time to time.

"Stone, have you studied the essence of steel casting that Master Sun talked about today?" At the entrance of the College of Engineering, Niu Dali grinned and patted Shi Kai, who had just come back from outside, and asked.

"That's natural, I'm majoring in smelting, this is the guy I'll eat later, oh yes, didn't your father arrange for you to go home on this turn to discuss Najib's matter? Why haven't you gone back yet? Shi Kai said with a wicked smile.

Seventeen or eighteen years old has reached the age of marriage in Daming, but this is still a topic worth talking about for each chick.

"Why does a husband have no wife? Let's go back and teach me how to make steel, what Master Sun said is too complicated for me to understand. Niu vigorously glared at Shi Kaidao.

His father Niu Dayong worked as a blacksmith in the ordnance institute, originally Niu Dayong wanted his son to inherit his father's business and let Niu Dali go to the engineering college to learn smelting, but Niu Dali did not listen to his father and stubbornly chose the mining department.

As an older generation of craftsmen, Niu Dayong refused to let the work in his hands be lost, and his son went to the industry of the king of Anguo County for further study.

Lao Niu's family is raised by the king of Anguo County, people must know how to be grateful, even if the king of Anguo County asks his son to pick up dung, he has no opinion.

So Lao Niu figured out a new method, a method that would not affect his son's learning of mining from the engineering college, nor would it affect the inheritance of the craftsmanship in his hand.

Have another baby!

Of course, although Lao Niu is not old, he has no heart to work hard, and he has also saved some family wealth in the armory in the past two years, thinking about getting a wife for his son to come back, so that he can take his grandson to take over his class as soon as possible.

It's just that this matter is said to his son Dali, Lao Niu was almost angry, saying that the big husband has no wife, Da Ming has always been the order of his parents, the last time he came back from the rest, the old Niu was going to repair Niu Dali, Niu Dali ran away naturally, and the father and son are still in a mood.

Niu Dali didn't tell Shi Kai much about his wife at home, but just pulled Shi Kai to go to the laboratory of the science and technology building.

"Why do you work so a minor subject when you major in mining?" Shi Kai scratched his head and said.

The two of them are good buddies, and Shi Kai naturally will not refuse Niu Dali's request, but he feels that it is too much.

"Song Shanchang once taught us that the study of science and engineering is interconnected, we must be inclusive, apply what we have learned, and let us understand the principle of all things. Niu said with a shy face.

In fact, he didn't want to go back to see his father's stinky face, all his thoughts were now on his studies, where would he have time to think about marriage.

And he learned this steel casting to prove to his father that even if he majored in mining, smelting would not fall behind, and he would be even more bullish than his father, because he studied steel casting and science!

The essence of steel casting is a textbook compiled by Uncle Song and several steel casting craftsmen with the permission of Liu Hong, and it is an extremely important course even in the College of Engineering.

Steel is a strategic material, and the announcement of the method of casting steel in the School of Engineering is also a decision made by Liu Hong after careful consideration.

Originally, he thought that steel should be the top secret of the Ming Dynasty, after all, steel muskets and artillery are much stronger than copper and iron, and this advantage is not only reflected in the range, but also in the weight.

Steel is much tougher than copper and iron, which means more gunpowder can be put to make the projectile shoot farther and lighter.

It was only later that Liu Hong gradually realized that this was contrary to the original intention of the establishment of the School of Engineering, and that secrecy was important, but inheritance and improvement were more important than secrecy.

Only when more descendants of the Ming Dynasty have learned the true inheritance can they invent more valuable things on this basis, rather than just the secret master-apprentice inheritance of some craftsmen in the ordnance institute.

That's too petty, and converter steelmaking is just a way to smelt steel, even if it is really passed on by some ill-intentioned people, he is not afraid, he is confident that he can crush the unsubordinated people in science and technology.

"Let's go, let's go, you're really, what's wrong with begging a wife, I've heard that you can ...... if you have a wife."

Bell bell bell - bell bell - bell bell -

While Shi Kai was talking, the bell on the top floor of the science and engineering building in the College of Engineering was ringed.

"The academy rarely rings the bell, I guess there is something important to announce, let's go gather first!" Niu Dali and Shi Kai glanced at each other and said in a deep voice.
