Xu Yue calmed down her tense nerves before continuing to answer Zheng Sanhao's questions.
"It's not easy to extract nitric acid. Where do you get your raw materials? What tools do you use to purify them?" Xu Yue asked.
Zheng Sanhao replied: "Part of it is saltpeter 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 used iron pots and pottery jars instead. The effect is
It’s just as good!”
Xu Yue was surprised again, "So, you have already tried and succeeded?"
Zheng San nodded sheepishly. She had indeed succeeded, but because there were not many raw materials for saltpeter, she only had a little bit.
Xu Yue looked at Xu Fubao again. If it had been before, she would never have thought that this mathematical genius would be involved in the production of explosives.
Moreover, in this small team, she seems to be the same core figure as Zheng Sanhao.
"Chief, I have drawn the kinetic energy image of the black powder explosion. I found that the black powder has only two simple explosion point directions, but the formula I learned in class told me that there are actually multiple points on the coordinate axis.
..."
Fu Bao began to talk to Xu Yue about her findings with great interest.
Facts have proved that she used the mathematical formulas she had learned and deduced 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 top geniuses like Sima Yi gradually showed confusion in their eyes because they had not systematically studied Xu Jiajun's mathematics.
In the end, only Xu Yue could keep up with Fu Bao's thinking and knew what she wanted to express.
Fu Bao said seriously: "The leader always said that we are looking at the world by standing on the shoulders of giants, and he asked us to combine what we have learned with all aspects of the real world."
"But now I find that after using the formula to deduct backwards, some of the things we learned are actually incomplete. Does it not exist in the first place, or is it hidden?"
Hearing this, Xu Yue's mind was already full of words: Cao Cao Cao Cao!
Of course she hid a lot of things, such as electricity, steam, chemical formulas that can create thermal weapons, and many, many things that were too advanced.
But now, looking at the appearance of black powder, Xu Yue felt that she might really have to revise the textbook.
That dangerous and mysterious part was precisely because it was extremely dangerous, so she deliberately hid it.
But now that they have been dug out by the students themselves, since she already has the correct formula, it is impossible for her to let the students take another risk and make the same sacrifices as the giants.
But before that, she needs to be quiet!
"Let's go eat first. Your group will suspend the research on black powder for the next few days. This thing is more dangerous than you think!"
After leaving this warning, Xu Yue decisively slipped away, ignoring the disappointed looks of Fubao and others.
She was afraid that if she stayed any longer, she would be exposed to the cruel reality that she was unable to handle the students' questions.
Xu Dalang waved to the guards in the village and collected all the messy utensils from the students.
They also took people to Zheng Sanhao's house and sealed up all the iron pots and jars in her backyard.
The students looked anxiously and wanted to explain something, but were frightened away by Xu Dalang's cold eyes.
At this time, they did not know that the reason why Xu Dalang did this was just to obey Xu Yue's order and protect their fragile lives.
No one knows this stuff about explosives better than Xu Dalang.
He is a mighty zombie king, but he was blown away by this thing until there was no trace left!
Students like Fubao and Zheng Sanhao were really just lucky. After all, a small amount of black powder would only blow people up black, not kill them.
But if the quantity is doubled, it’s hard to say...
Xu Yue locked herself in a small dark room. It was not until Xu Erniang returned to Yuyang in a carriage with the twins 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 topic.
"You don't know if you should 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 try.
Xu Yue took out the Coke, poured half the can for her sister, and kept half the can for herself. She took a big sip first and burped with satisfaction.
The worries of the past few days also disappeared with this hiccup.
The technology tree prevents her from destroying the balance, but this balance was not broken by her, and it cannot be blamed on her!
"Sister, what do you think?"
Xu Erniang said with a smile: "I think you are worrying too much. Explosives are not easy to make. If you want to use them on a large scale, how many raw materials are needed?"
"Not to mention anything else, it's just that saltpeter is hard to find. Let them go through the trouble with this small amount."
Xu Erniang was very open-minded and said, "Give it out for us to use for coal mining, limestone mining, etc. If there are explosives for blasting, the output can be increased several times compared to now."
Xu Yue stayed in the small dark room for a few days, and of course she also thought about these benefits.
but......
"Zheng Sanhao said she was going to get nitric acid. I'm really afraid that if she gets nitroglycerin out, if she blows herself up among other things, we will lose a talent that we have carefully cultivated for many years!"
The curiosity of young people is what gives Xu Yue the biggest 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 panicking now..."
Xu Yue shook her head to calm down, "How can they be so smart? Especially Xu Fubao, why didn't I know that mathematics was so good before?"
Xu Erniang rolled her eyes speechlessly and told the truth, "Don't you teach too much?"
"But this is a foreseeable fact. Don't be too nervous. Let's implement safety education first."
Xu Yue asked tentatively: "What do you mean, sister, 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 seems to be more powerful than my holy light~"
Xu Yue thought to herself, this is really possible.
"To be on the safe side, let's ask my parents and eldest brother what they think." Xu Yue took out the walkie-talkie.
Xu Erniang had no objection and got up and called Xu Dalang in. The family of five held a small family meeting through the intercom.
The theme of the meeting was: Whether necessary intervention should be carried out on the natural development of students.
After a brief ten-minute meeting, the family of five came to a common conclusion:
Do a good job in safety education, fill in the gaps in teaching materials, and leave the rest to time.
So, the three Xu Yue brothers spent the night reinstalling the content that they and others had removed from the textbook.
After that, all the students were called together and a serious safety education meeting was held to make the students realize that doing science is life-threatening!
