At this time, Wen Changyao and others had completely sobered up. They didn't know why the leader was so interested in the medicinal powder that he and others had made to catch frogs, but they still honestly explained the cause and effect.
"It turns out that Sister Sanhao said that charcoal, nitrate, and sulfur can kill insects and prevent moisture plagues, so she asked Fubao and us to work together to make some pills with these raw materials in proportions for everyone's daily use...
"
Then, after rubbing it together, things began to develop in a direction that neither of them expected.
By chance, the meatballs rolled out of these three ingredients actually started to burn, and then there was a bang, and the clay pot used to hold the meatballs was blown to pieces.
At that time, because it was done in a laboratory and the pellets were relatively small, it did not cause many people to feel the effects.
Zheng Sanhao was shocked at first, but there were no casualties at all. The students checked for a while and guessed that the charcoal and saltpeter powder might have burned and the temperature was too high, so the clay pot couldn't bear it and cracked.
Since there were no casualties and the explosion range was too small, the students didn't take it seriously.
Only Xu Fubao squatted at the site after the explosion and watched for a long time. Then, because of his sensitivity to numbers, Fubao suddenly thought of the ratio of pills.
After final verification, she discovered that there was a difference between pills that could explode and pills that couldn't.
Then, the students began the formal first explosion experiment, which was the day when Wang Dayou and others discovered the loud noise.
This loud noise frightened Zheng Sanhao and Xu Fubao, but from then on, they seemed to have discovered a new world and were out of control.
"These two bottles of black fire powder were reconstituted by Fubao and Sanhao. Press a small amount into a bamboo tube and ignite it with a twisted cotton thread. It will explode and knock out all the fish and frogs in the river."
Wen Changyao explained proudly, while also adding in his mind that now he no longer has to go to the fields to catch frogs in the middle of the night.
Fubao and Sister Sanhao are also thinking about increasing the concentration to make more powerful black fire powder. Maybe it can be used directly to fry wild boar nests.
Xu Yue listened quietly to Wen Changyao's explanation of the causes and consequences. She realized that the students had not yet understood the true use of gunpowder, and she breathed a sigh of relief.
It was getting very late, and the results had already been seen. Xu Yue's heart had also settled down, and it would be too much to keep struggling.
Then he waved his hand and told Wen Changyao and others to go back and rest. When they wake up tomorrow, they will demonstrate to her again how they used black powder to fry small fish and frogs.
"I will keep these two bottles of black powder first." Xu Yue confiscated the two bottles of black powder naturally.
Although this kind of homemade black powder is not very lethal, it is really not reassuring to have a group of students who know nothing about it holding it in their hands.
Wen Changyao and Xu Fubao looked at each other, and out of absolute trust in their leader, they nodded obediently and did not take back the black fire powder that they and others had worked so hard to develop.
Watching the students return to the dormitory, Xu Yue turned to the three people behind her and said, "Let's rest first and we'll talk about it tomorrow morning."
After struggling for most of the night, Sima Yi finally got rid of most of his curiosity when he saw what the shocking person looked like. He followed Xu Yue back to the Xu family's old house and fell asleep.
The next day, he got up early just to see what effect this black powder could have.
Xu Yue got up early and didn't seem to be in good spirits. She must have not slept well last night.
Junmei brought breakfast from the school cafeteria, and the four of them ate together and then walked towards the school.
Zheng Sanhao, who had been notified in advance, was already in place. Together with Xu Fubao, Wen Changyao, and two other medical graduates, the group came to the village with the two bottles of black powder confiscated by Xu Yue last night.
By the river.
Xu Yue handed them a bottle of gunpowder, led everyone back to a safe distance and stood, nodded, indicating that they could start.
I saw students bringing in a bunch of small bamboo tubes, each one only as thick as a finger and made of bamboo.
Zheng Sanhao took out the kneaded cotton thread from the prepared box and put it in the bamboo tube first, leaving a section exposed.
Then use a ceramic spoon to scoop out a spoonful of black powder and pour it into the bamboo tube. Finally, pick up a piece of wet mud from the roadside and seal the mouth of the tube.
In this way, a simple mini bomb is ready.
Wen Changyao took the small bomb, picked up the sandalwood stick handed over by Xu Fubao, and lit the cotton thread.
With a click, the cotton thread ignited, making people nervous for no reason.
Wen Changyao, however, seemed to have done this many times before, waiting patiently for the exposed cotton thread to burn to the end, and then threw it hard into the river.
There was a soft "thud" sound, and the small bamboo tube was submerged into the river, and then a stream of gray bubbles came out, and then, with a "thud" sound, high water splashed on the river!
Everyone on the shore was standing far enough away, but their clothes were still splashed by flying water.
Xu Yue, who had expected it for a long time, looked as usual, only her pupils contracted for a moment.
But Sima Yi and Jun Mei were different. For the first time, they felt the power of the explosion at such a close distance.
Although the spray that burst out was harmless, the loud noise and the two or three fish slowly floating on the river showed that this small bamboo tube contained a huge threat.
"That's amazing!" Jun Mei said in surprise.
This is only a small spoonful. If two spoons are added, wouldn't the power be doubled?
Sima Yi clenched his fists hanging by his sides, and turned his gaze to Xu Yue, who looked as usual, with a dark look in his eyes.
This black powder is probably not as simple as hearing a sound.
Moreover, seeing Xu Yue's unsurprised look, she seemed to have known about the existence of this black medicinal powder for a long time.
There is probably only one reason that could have caused her to act so rude yesterday.
That is - she didn't expect that the students in Zhuangzi could make this black medicinal powder!
The small explosion display was successful. Wen Changyao and others came to Xu Yue with the stunned fish, excitedly waiting for praise.
Zheng Sanhao said: "Chief, I guess the power of this black fire powder can be improved to a higher level, so I have recently been thinking of ways to extract more concentrated nitric acid from saltpeter. I want to continue to try more formulas. What do you think?
How about it?"
Nitric acid?
Xu Yue stared. For the first time, she felt so strongly that students were too eager to learn, which actually frightened the teacher.
This Zheng San is so good, is it possible that she still wants to perform nitroglycerin surgery on her?
If this is the case, explosive thermal weapons will surely sweep across all battlefields!
Xu Yue took a deep breath, suppressed her overly nervous nerves, looked at the innocent eyes of the students, and thought, maybe the people who made the explosives at the beginning didn't know what they would bring to the world.
