Don't panic, the family boss is busy farming

Chapter 456

Xu Yue eased her tense nerves before continuing to answer Zheng Sanhao's question.

"Extracting nitric acid is not easy. Where does your raw material come from? What tools do you use for purification?" Xu Yue asked.

Zheng Sanhao replied: "Part of it is nitrate ore, and part of it is extracted from horse urine and pig manure. The utensils in the laboratory are too precious, so I thought about it later and replaced it with iron pots and pottery jars. It's just as good!"

Xu Yue was taken aback again, "So, you have tried it successfully?"

Zheng Sanhao nodded embarrassingly. She has indeed succeeded, but because there are not many raw materials for nitrate, there is only a little bit.

Xu Yue looked at Xu Fubao again. If it was before, she would never have thought that this math genius would participate in the production of explosives.

And, in this small team, she seems to be the same core figure as Zheng Sanhao.

"Boss, I have drawn the kinetic energy image of the black fire powder explosion, and I found that the black powder has only two simple directions of explosion points, but the formula I learned in class before told me that there are actually multiple points on the coordinate axis. "

Fu Bao began to tell Xu Yue about her discovery with great interest.

Facts have proved that she used the mathematical formulas she had learned to deduce that there is a more powerful explosion method than black powder, thus giving Zheng Sanhao the correct research direction.

This is beyond the scope of what ordinary people can understand. Even Sima Yi, a top genius of the era, gradually revealed confusion in his eyes because he had not systematically studied Xu Jiajun's mathematics.

In the end, only Xu Yue could keep up with Fu Bao's thinking and understand what she wanted to express.

Fu Bao said seriously: "The leader always says that we look at the world by standing on the shoulders of giants, and wants us to combine what we have learned with all aspects of the real world."

"But now I find that after using the formula to reverse deduce, what we have learned is actually partially incomplete. Does it not exist in the first place, or is it hidden?"

Hearing this, Xu Yue's mind was already full of screens: Hasty, hasty!

Of course she hides many things, such as electricity, steam, chemical formulas that can make thermal weapons, and many, many things that are too advanced.

But now, seeing the appearance of black powder, Xu Yue felt that she might really have to revise her textbooks.

That dangerous and mysterious part is precisely because it is extremely dangerous, so she deliberately hides it.

But now that they have been dug out by the students themselves, since she already has the correct formula, it is impossible for the students to take another risk and make the same sacrifice as the giants.

But before that, she needs quiet!
"Let's go eat first. Your team will suspend the research on black medicine powder for a few days. This thing is more dangerous than you imagined!"

After leaving this warning, ignoring the disappointed gazes of Fu Bao and others, Xu Yue decisively slipped away.

She was afraid that if she stayed any longer, she would expose the cruel reality that she could not cope with the students' questions.

Xu Dalang waved to the guards on the farm, and took away all the messy utensils of the students.

They took people to Zheng Sanhao's house and sealed up all the iron pots and jars in the backyard of her house.

The students watched anxiously and wanted to explain something, but they were scared off by Xu Dalang's glamorous pair.

At this time, they didn't know that the reason why Xu Dalang did this was to obey Xu Yue's order and protect their fragile life.

No one knows explosives better than Xu Dalang.

He is a majestic zombie king, but he was blown up to nothing by this thing!

Students like Fu Bao and Zheng Sanhao are really just lucky. After all, a small amount of black powder will only blow up people, not kill them.

But if the number is doubled, it's hard to say
Xu Yue locked herself in a small dark room, and it was not until Xu Erniang returned to Yuyang with the twins in a carriage that she opened a crack in the door and let her sister in.

"I've heard about the black powder."

As soon as Xu Erniang entered the door, she went straight to the point.

"You don't know whether to let the students continue to do it?"

Xu Erniang sat down cross-legged opposite Xu Yue, and asked Xu Yue to bring out a can of Coke for herself to taste.

Xu Yue took out the Coke, poured out half a can for her elder sister, kept half a can for herself, took a big gulp first, and burped contentedly.

The worries of the past few days also dissipated with this hiccup.

The technology tree doesn't allow her to break the balance, but she didn't break the balance, so it can't be blamed on her!
"Sister, what do you think?"

Xu Erniang laughed and said, "I think you're worrying too much. Explosives are not easy to make. If you want to use them on a large scale, how many raw materials do you need?"

"Not to mention anything else, it's just that saltpeter is hard to find. Let them toss about this amount."

Xu Erniang was very open, "Get it out for our own use, such as coal mining, limestone mining, etc. If there are explosives to blast, the output can be increased several times compared to now."

Xu Yue stayed in the small black room for a few days, so of course she also thought about these benefits.

but.
"Zheng Sanhao said that she wants to make nitric acid. I'm really afraid that she will get out nitroglycerin. If nothing else, if she blows herself up, then we will lose a talent who has been carefully cultivated for many years!"

The young people's curiosity is what makes Xu Yue feel the most headache.

If you don't do it, you won't die, but they won't remember this advice.

"There is also cotton. Cotton is also one of the important raw materials for making bombs. I am really panicked now"

Xu Yue shook her head, trying to calm herself down, "How can they be so smart? Especially Xu Fubao, why didn't I know that mathematics is so good?"

Xu Erniang rolled her eyes speechlessly, and told the truth, "Isn't it because you teach too much?"

"But this is a foreseeable fact. Don't be too nervous. Let's implement safety education first."

Xu Yue tentatively asked: "What does sister mean, let them develop naturally?"

Xu Erniang nodded and smiled jokingly, "Maybe I can still use the electric light you always talk about in my lifetime. It is as bright as day, and it seems to be more powerful than my holy light~"

Xu Yue thought to herself, this is really possible.

"Just to be on the safe side, let's ask my parents and elder brother what they think." Xu Yue took out the walkie-talkie.

Xu Erniang had no objection, she got up and called Xu Dalang in. The family of five held a small family meeting through the walkie-talkie.

The theme of the meeting is: whether to make necessary interventions on the natural development of students.

After a brief 10-minute meeting, the family of five came to a common conclusion:
Do a good job in safety education, supplement the vacancies in teaching materials, and leave the rest to time.

So, the three Xu Yue brothers and sisters reinstalled the part of the textbook that they and others removed from the textbook overnight.

Afterwards, all the students were called together, and a serious safety education meeting was held to make the students realize that engaging in science is risky!
