I heard that the village chief Liu Delin said that Zhang Ran specially recruited himself to join the Eighth Route Army, no need to fight, food and shelter, and a dollar every month, although I don't know what Zhang Ran wants to do by himself, but Mao Ran still wants to leave for Yanggou Village immediately.

However, after muttering to his family, Mao Diamond finally decided to slow down and see how it went.

After all, this joining the army is not a militia, once you come over, you will be a full-fledged soldier, you have to obey the order, saying that you will not fight, but if the order comes, then can you not do it?

But these days, witnessing the division of land in the village, and the division of more than 20 acres of his own family, there are still people who have been cleared of wasteland, and Mao Diamond finally made up his mind to come over!

I have land and land, if the little devil comes and lets me rush up to fight for the little devil, then I have to go up!

Not to mention for others, just to protect their own fields, isn't it worth fighting for your life?

"Take it easy!"

Zhang Ran looked at Mao Drill, who was standing in front of him with a dead face, and couldn't help beckoning him to sit down before saying, "Will you make a bomb?" ”

"Bombs?"

Mao Drill was a little dizzy, and said, "I'm a cannonballer......"

"Artillery is like a bomb!"

Zhang Ran said with a smile: "At least you understand the principle of this aspect, let's work together and we can always make a bomb, what do you say?" ”

Mao Zuan's heart was bitter, and he said in his heart that this artillery battle, why is it almost like a bomb?

"I know it's very difficult, but our Eighth Route Army, the last thing we are afraid of is difficulties, if there are difficulties, then rise to the occasion - as the saying goes, where there is a will, there is a way!"

Zhang Ran patted Mao Zuan's shoulder and said, "Comrade Mao Zuan, I announce that you are now not only a member of my glorious Eighth Route Army, but also promoted-Minister of Ammunition, with the rank of second lieutenant!" ”

I was thinking that I might as well stop being the Eighth Road, and continue to do artillery battles when I went home to farm and was idle, but when my wife and children heard the word promotion, they immediately raised their eyebrows and asked: "Captain, what kind of officer is this second lieutenant?" ”

"You know, old crutch? He's now a platoon leader! ”

Zhang Ran smiled and said, "You second lieutenant, one level older than his officer!" ”

"Then I'll try - think about this artillery battle, it's almost like a bomb, it's not all a bomb!"

Mao Zuan suddenly became arrogant, and said in his heart that now everyone in ten miles and eight towns knows this Jindong detachment, except for Zhang Ran, the captain, and the platoon commander Wang Laogui is bigger, and now, he is bigger than Wang Laogui......

When I thought about it, my heart was beautiful, and the back sockets of Le came out.

It is naturally excellent to make bombs, TNT and nitrification high explosives.

But these things, the Jindong detachment obviously does not have at present, and it is impossible to create them in a short period of time!

So this bomb, Zhang Ran is also ready to start with the black powder bomb.

Compared with the power of bombs made of black powder and the power of bombs made of high explosives, it is the difference between grandchildren and grandparents.

But there is no way, something is better than nothing!

To make a bomb with black powder, you must first have black powder, and to make black powder, you must have nitrate.

The main ingredients of black powder are well-known, nitrate, sulfur, charcoal!

Sulfur charcoal is easy to find, but nitrate is not good, so you can only boil it yourself.

The black powder used by Mao Drill for artillery battles is all configured by himself, so it will also be boiled.

However, because he uses a small amount of artillery for cannonballs, he usually collects some corner soil and boils the soil around the pigsty in winter.

Not on the side of the Jindong detachment, the output of boiling nitrate is too small, and it is necessary to boil cave nitrate.

Fortunately, there are many caves in the mountainous areas here.

In the past few days, Zhang Ran has also taken a turn in the surrounding mountains, and also asked Wang Changtian to inquire with the people and village chiefs of the surrounding mountain villages, there are still many caves, and if you really want to boil it, you can boil a lot of cave nitrate.

Zhang Ran simply knew the process of boiling nitrate, if he wanted to come by himself, it would not be impossible to boil it, but it would take a lot of time to explore.

Now, with the head of the Ammunition Department of the second lieutenant, he is much more relaxed.

Let Wang Changtian dispatch the clever activists in each village to listen to Mao Zuan's lectures, and then follow Mao Zuan to boil a batch of nitrate, and let the villages organize militias to boil in the surrounding caves.

Although there is a professional such as Mao Drill, Zhang Ran can leave it alone about the nitrate boiling, but the affairs of the village team are almost arranged, and he is still happy to follow to see the process of boiling nitrate and increase his knowledge.

Cave nitrate cave nitrate, is to use the nitrate in the cave to boil nitrate, but by no means any cave can boil nitrate!

There are two elements of nitrate, one is nitrate, and the other is water!

Nitrate is found in most caves, but not necessarily water.

Because the water that boils nitrate must not only be the water in the cave itself, but also the best stagnant water!

Because the stagnant water in the cave also fuses a large number of nitrate-containing elements, which can greatly increase the nitrate rate, if you use the water outside, it is estimated that the water reacts with the elements in the nitrate, which will greatly affect the nitrate rate.

In the steep mountain, Mao Zuan checked the environment of the cave, tasted the nitrate and water in the cave, and then waved his hand quite arrogantly: "This is it - I want to dig a pit!" ”

Of course, the pit for boiling nitrate is dug outside the cave, and according to the amount of nitrate that may be produced in the cave, how big and how big can be dug and how big it can be dug.

Seeing Zhang Ran's interested expression, Mao Ran was also full of pride, and explained to Zhang Ran some of his experiences in this area, such as nitrate, which can be divided into four tastes: sweet and sour, spicy is the best, bitter is second, and then sweet and sour.

Zhang Ran looked at the white nitrate earth and felt a diaphragm in his heart, but when he saw Mao Diamond's kind face, he was so enthusiastic that he had to learn from Mao Diamond and taste it.

He didn't taste the spicy, but a strong musty smell rushed straight to his nose, and he was busy vomiting, indicating that he was really not talented in this area.

The militia in the cave dug up the nitrate soil under the auspices of the Mao Drill, and then transported it out of the cave and piled it up next to the nitrate pit.

The nitrate soil in the cave, that is not as deep as you want to dig as deep, a shallow layer above the planing is enough, and then the deep soil does not contain much nitrate, not to mention the loss of the effort, but also greatly increases the time to boil nitrate.

A group of people were in full swing, and the cave was full of smoke and dust.

Zhang Ran found an excuse to sneak out, after all, this dust sucked too much, which is not a good thing for the body, if you get a pneumoconiosis or something, it will really be a calf.

The nitrate pit outside the cave is huge, full three meters square.

At this moment, several strong militiamen were holding the tools of building the earth wall and rammed the bottom and wall of the pit fiercely, and a small hole was drilled in the center of the bottom of the pit, which was guided to the exit of the low-lying place next door with a thin bamboo pipe bent by fire.

Zhang Ran knew that the seeping nitrate would flow out of this thin bamboo pipe, and then it would be connected to the container, and it could be boiled!

"Minister Mao, what is this nitrate pit going to be built?"

Seeing that a few strong militiamen had built the four walls of the pit for two or three hours, but Mao Zuan was still not satisfied, and he had to continue to build it after lunch, Zhang Ran asked curiously.

"It must be tightened, the tighter the better, and it must be as smooth as a mirror!"

Mao Drill said: "Otherwise, this nitrate water will seep into the soil from all around, then we will be busy in vain!" ”

It wasn't until half an afternoon that Mao Drill expressed his satisfaction with the situation of the pit, and asked the militiamen to put wooden sticks densely on the bottom of the pit, and a thick layer of grain poles was laid on top of it, completely separating the nitrate from the bottom of the pit, and then began to put the mountain of nitrate soil next to the nitrate pit into the pit.

After putting a small layer of nitrate, the militiamen jumped into the pit and used tools to build the nitrate under the command of Mao Drill, and the requirements were still the same, the tighter the better!

Wait for a layer of nitrate to be built, and then put another layer of nitrate into it, and the militia did not continue to jump into the pit, and build it again and again!

It wasn't until it got dark and the nitrate in the pit was finally half full, that the drill told the militiamen to stop and began to carefully pluck out the water from the cave with wooden barrels and pour it into the pit.

The earth is too tight, and the water penetrates very slowly!

Next, it's time to wait!

After the water leaks, add water, and repeat the cycle again and again, until the nitrate in the nitrate pit is gone.

"Then how can you tell if the nitrate in this pit is gone?" Zhang Ran asked with great interest.

"That's easy!"

Mao Zuan smiled: "The smell of the water that has just seeped out is as choking as cow urine and cat urine, and when the smell of nitrate water is the same as the urine of people who drink too much water, there will be no nitrate in the soil - when the nitrate water comes out, the captain will know if you taste it!" ”

"Then forget it!"

Zhang Ran waved his hand and politely declined Mao Drill's earnest invitation, after all, he was not interested in knowing what cow pee, cat pee, and human urine tasted like.

Knowing that this nitrate pit was built so well that it would take at least three days for the nitrate water to penetrate out, Zhang Ran went down the mountain with the village soldiers who had initially learned the nitrate boiling process, and asked Mao Zuan to take some militiamen to watch here, and he waited for the nitrate water to come out before coming to inspect the inspection work.
