Soil nitrate is a white crystal, like salt and white sugar. Of course, it can also be mixed with a certain amount of water glue to make crystals like rock sugar cubes.

In fact, he hasn't done it before, and even said that he hasn't touched it with his own hands, but has only seen it in the picture.

To be honest, he has no idea what the first time he is doing. It is normal to fail, even if he fails two or three times, he can bear it.

The first time I succeeded, it was a good start. It also played a psychological boost to him.

Yuan Chenming smiled and gave a positive reply with confidence: "Instructor, it's Tu Ni, we succeeded."

Dancing and dancing, and in front of so many warriors, that was not something that Yuan Chenming, who was introverted, could do.

It was just a kind of joy conveyed in a louder voice than usual, and efforts were not in vain.

Wang Desheng was even more excited than him, and his old farmer's face was almost smiling like a chrysanthemum.

It’s not just because he is the one who does it, but also because he understands how much effect it can play after doing this thing successfully.

If one grenade is lucky, it may blow a Japanese devil. If ten thousand grenades are built, how many can it kill?

It's exciting to think about it.

One has increased and the other has decreased. Massive production of grenades is definitely an important support for the Eighth Route Army's great cause of anti-Japanese war.

When Lu Wenyuan saw the two of them laughing happily, his heart was like a cat scratching his heart: "These two of them made gunpowder and wanted to do something, what's the fun?"

He thought so, and he was eager to know the answer. He reached out and pulled Wang Desheng's sleeve: "Old Wang, let's go back to the house to talk."

Wang Desheng knew what his partner was thinking, but he could not disclose it casually even if he promised to keep it secret.

Unless Yuan Chenming himself allows.

The company commander and instructor left, and Yuan Chenming didn't want to stay in this yard and be seen like a giant panda - although he had already enjoyed such treatment.

"Wang Maomao, take all the earth and salt back to my room and place it on the table in the outer room."

"Who, don't pour this pot of water, leave it for the instructor to deal with it."

Yuan Chenming walked into his house after making some tricks.

Unexpectedly, someone called him, and he was Chen Li, who had the most outstanding training results in the past two days and was regarded by the company commander Lu Wenyuan.

"A great scholar, I heard that you are very knowledgeable, so how can you tell me what's going on?"

Yuan Chenming stopped and looked back. Chen Li didn't like him, he could feel it.

If he is the only one who is curious, then make him curious.

But the other soldiers looked at him eagerly, just like the children in the mountain village, with their eyes full of curiosity.

For them, everything is fresh.

Yuan Chenming decided to talk about the desire for knowledge by other soldiers without much hesitation: "The earth and salt are just the things like salty salt, which are actually not strange things.

This thing has been made by people for a long time, and is used to make animal furs, or to make ice cubes, and to make black gunpowder, which is quite useful.

By the way, have you ever eaten tofu?"

A soldier said excitedly: "I have eaten it, it is white and tender, so delicious."

Some soldiers agreed and said that they had eaten it. Some soldiers hadn't eaten it yet, and they became even more curious about it.

Yuan Chenming continued to tell, "The soybeans are crushed and cooked, and that is soy milk. The pot of water after boiling the nitrogen is called brine.

When adding tofu to brine, it means that adding the water to soy milk in a certain proportion will get the white and tender tofu you want to eat.

In addition, the pot of water used as fertilizer to water the soil can greatly improve the fertility of the soil, which means it can produce more crops."
