Don't panic, the family boss is busy farming

Chapter 455 Nitric Acid
At this moment, Wen Changyao and the others had completely woken up. They didn't know why the leader was so interested in the frog-catching powder that he and the others made, but they still honestly explained the cause and effect.

"Originally, Sanhao sister said that charcoal, nitrate, and sulfur can kill insects and prevent moisture plague, so we asked Fubao to make some pills with these raw materials according to the ratio, so that everyone can prepare them for daily use."

Then, after rubbing and rubbing, things began to develop in a direction that none of them expected.

By chance, the meatballs rubbed out of these three materials actually caught fire, followed by a bang, and the clay pot used to hold the meatballs was blown apart.

At that time, because it was in a laboratory and the meatballs were relatively small, it didn't cause many people's effects.

Zheng Sanhao was also taken aback at first. There were no casualties. The students checked for a while and guessed that the charcoal and saltpeter powder might be burning. The temperature was too high, so the clay pot could not bear it and cracked.

Since there were no casualties and the range of the explosion was too small, the students didn't take it seriously.

Only Xu Fubao squatted on the field after the explosion and looked at it for a long time. Then, because of his sensitivity to numbers, Fubao suddenly thought of the ratio of the pills.

After a final check, she found a difference between the pills that exploded and those that didn't.

Then, the students started the first formal explosion experiment, which was the day when Wang Dayou and others discovered the loud noise.

This loud noise scared Zheng Sanhao and Xu Fubao a little bit, but after that, the two seemed to have discovered a new world, and they were out of control.

"These two bottles of black fire powder were remixed by Fubao and Sanhao sister. Take a small amount and press it in a bamboo tube, and ignite it with twisted cotton thread. It can explode and blow up all the fish and frogs in the river."

Wen Changyao explained proudly, and at the same time added in his heart that now he no longer has to go to the fields in the middle of the night to catch frogs.

Fubao and Sanhaojie are still thinking about increasing the concentration to make more powerful black fire powder. Maybe they can be used to fry wild boar nests at that time.

Xu Yue listened quietly to Wen Changyao's explanation of the cause and effect, and realized that the students hadn't understood the real usage of gunpowder, so she breathed a sigh of relief.

It was already very late, but it turned out that Xu Yue's heart had also fallen to the ground, and it would be a bit too much to continue to toss.

Then he waved his hand and asked Wen Changyao and others to go back and rest. When they woke up tomorrow, they would show her how they used black powder to fry small fish and frogs.

"I'll keep these two bottles of black powder first." Xu Yue naturally confiscated the two bottles of black powder.

Although this kind of black powder made by homemade methods is not very lethal, it is really not reassuring to let a group of students who know nothing about it hold it in their hands.

Wen Changyao and Xu Fubao looked at each other, and out of absolute trust in the leader, they nodded obediently, and did not ask back the black fire powder that they and others worked so hard to develop.

Watching the students go back to the dormitory, Xu Yue turned around and said to the three behind her: "Let's rest first, we'll talk about it tomorrow morning."

After tossing and tossing for most of the night, I finally saw what that earth-shattering Sima Yi looked like. Most of his curiosity was successfully dissipated, and he followed Xu Yue back to Xu's old house and fell asleep.

The next day, he got up early, just to see what effect the black medicinal powder could have.

Xu Yue also got up early, and she didn't seem to be in a good mood. She must have not slept well last night.

Junmei brought breakfast from the school cafeteria, and the four of them ate together, then walked towards the school.

Zheng Sanhao, who had been notified in advance, was also in place, together with Xu Fubao, Wen Changyao, and two other medical graduates, a group of people took the two bottles of black powder confiscated by Xu Yue last night, and came to the village in a mighty manner. By the small river.

Xu Yue handed them a bottle of gunpowder, led everyone back to a safe distance, and nodded, indicating that they could start.

I saw the students carrying a bunch of small bamboo tubes, each about the thickness of a finger, cut from bamboo.

Zheng Sanhao took out the twisted cotton thread from the prepared box, put it in the bamboo tube first, and left a section exposed outside.

Then use a ceramic spoon to scoop out a spoonful of black gunpowder and pour it into the bamboo tube, and finally pick up a piece of wet mud on the side of the road to seal the tube mouth.

In this way, a simple mini bomb is ready.

Wen Changyao took the small bomb, picked up a sandalwood 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 it many times, waiting for the exposed cotton thread to burn to the end, and then threw it into the river vigorously.

With a soft "boom", the small bamboo tube sank into the river, followed by a burst of gray bubbles, and then, with a "boom", high water splashed on the river!

The people on the shore had stood far enough away, but they were still splashed on their clothes by the flying water.

Xu Yue, who had expected it for a long time, looked as usual, only her pupils constricted for a moment.

But Sima Yi and Jun Mei were different. It was the first time for them to feel the power of the explosion so close.

Although the explosion was a harmless spray, the loud noise, and the two or three fish slowly floating up from the river surface, all revealed that this small bamboo tube contained a huge threat.

"It's amazing!" Jun Mei exclaimed in surprise.

This is only a small spoonful, if two spoonfuls are added, wouldn't the power be doubled?
Sima Yi clenched his fists hanging by his side, and turned his eyes to Xu Yue, who had a normal complexion, his eyes were dim.

This black medicinal powder is probably not as simple as just hearing it.

Moreover, seeing Xu Yue's unsurprised expression, 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 make her behave like that yesterday.

That is - she didn't expect that the students on Zhuangzi could make this black medicinal powder!
The small explosion was successfully demonstrated, and Wen Changyao and others came to Xu Yue with the stunned fish, waiting excitedly for praise.

Zheng Sanhao said: "Boss, I guess the power of this black fire powder can be further improved, so I am also trying to find a way to extract more concentrated nitric acid from saltpeter, and I want to continue to try more formulas. What do you think? How about it?"

Nitric acid?

Xu Yue stared, it was the first time that she felt so strongly that the students were too eager to learn, which made the teachers feel scared.

This Zheng Sanhao, could it be possible that she still wants to fix the nitroglycerin for her?
If this is the case, explosive heat weapons will definitely sweep all battlefields!
Xu Yue took a deep breath, suppressed her overly nervous nerves, looked at the innocent eyes of the students, and thought to herself, maybe the people who made the explosives in the first place didn't know what they would bring to the world.
