The experimental explosives of the ammunition department are extremely dangerous, and they need a certain amount of secrecy, so they are directly set up in a large hole left after boiling nitrate, and the terrain is steep and easy to defend and difficult to attack.

It is twenty minutes away from Yanggou Village, and food and other things are delivered by people every day.

"Captain, I made it!"

As soon as he saw Zhang Ran, Mao Ran took a few guys and reported the good news to Zhang Ran and the others.

Seeing that Mao Drill was covered with dust and his beard was bloodshot, Zhang Ran remembered that since this guy was named a second lieutenant, except for the first two days in the village with his hands behind his back and swaying back and forth, enjoying the soldiers saluting when they saw him, and the villagers respectfully shouting the minister's majesty when they saw it, he hadn't appeared in his eyes for some time.

Seeing this guy's current appearance, Zhang Ran knew that Mao Zuan probably held his breath, and wanted to come up with results to prove that he could also make bombs as an artillery fighter, and he would not be able to give him the rank of second lieutenant in vain.

"This is the bomb?"

However, Wang Laogui and others held a few 'bombs' with a hair drill, looking puzzled, and said in their hearts that although we have never seen what this bomb looks like, but your bomb - this is clearly a large artillery battle!

Isn't it?

Except that it is much thicker than ordinary artillery battles, this bomb is really no different from artillery battles - the cannon body is made of soil paper layer after layer, the two ends are blocked with cement, and the ignition fuse is still swaggering in the breeze!

This is definitely a big cannon battle!

"It's a lot more powerful than a cannon fight, you didn't see it when it exploded, that guy...... Can the movement of the artillery battle be so loud! Mao Zuan blushed and argued.

"Artillery battle, it's not that big movement!"

Zhang Ran nodded with this cannon, looked left and right, and said that this was indeed different from the bomb he saw on TV.

Mao Diamond looked stunned, slanted at Wang Laogui and the others who questioned him, humming, and looked like the Minister of Ammunition was by no means in vain.

"Let's take a look at another one!"

Zhang Ran glared at Wang Laogui and the others fiercely, asking them to talk less nonsense, so as not to affect Mao Diamond's enthusiasm and then said.

Mao Zuan was about to light a bomb, but was stopped by Zhang Ran.

After all, what he wanted to experiment with was the power of the bomb, not whether it was a big move.

On a piece of flat land that had already been leveled, Zhang Ran asked Wang Laogui and others to erect a few scarecrows in a circle, about five meters away from the explosion point, and then pasted a layer of tissue paper on the scarecrow, which indicated that the drill could be experimented.

There was a loud bang, and smoke and dust were everywhere.

I have to say that this movement is indeed quite big, and the ears of the shock are buzzing.

But it's powerful......

The white paper pasted on the scarecrow did not even scratch the skin except for an extra layer of ash and a little scrap of paper.

"This bomb, awesome......"

Wang Laogui and the others screamed exaggeratedly, looked at Mao Zuan and ridiculed: "Our bomb, it is estimated that it is to scare the devil to death by moving, not by exploding?" ”

Mao Diamond blushed, gritted his teeth, and was about to say that Lao Tzu didn't do it!

Zhang Ran glanced at Mao Drill's expression and wanted to stumble, and without saying a word, Wang Laogui and others, who kicked with a few big feet, wailed again and again, and then turned back to Mao Drill and said: "Minister Mao, don't be discouraged, everything is difficult at the beginning, let's work together and find a way together, we will definitely be able to get the bomb out!" ”

"I've never seen a bomb before......"

Seeing Zhang Ran protecting himself like this, Mao Ran was embarrassed to stumble directly, and began to cry out with a bitter face.

"It's okay if you haven't seen it, I've seen it!"

Zhang Ran slapped his chest with a bang - decades later, in the TV movie, bombs and shells flew everywhere, he really saw a lot!

Holding a pen and drawing a sketch of a grenade for Mao Diamond, Zhang Ran explained the structure of the grenade.

The wooden handle is hollow, and there is an iron lump on it, and the black powder is contained in the iron lump.

After the explosion of black powder, it is the shattered steel fragments that kill the enemy, and the wooden handle is mainly thrown farther when it is lost, and the lead in it delays the explosion time, etc......

"Then the workload is huge......"

Hearing this, Wang Laogui and the others didn't realize anything, but Mao Zuan's face was already full of horror - in the end, he was professional, and he understood how difficult it was to simply make Zhang Ran's words into a finished product.

But the harder stuff is yet to come!

"When you go out to fight, you can't bring a fire bomb at any time, especially when you are in an ambush, it is easy to expose your whereabouts as soon as there is a fire, not to mention that it rains or something, we can't light this bomb!"

Zhang Ran continued: "So this grenade must not be ignited, and the process must be improved to make a device for pulling and detonating!" ”

"Ah......h

Listening to this, Mao Diamond is completely blinded - he is a cannon fighter, not a scientist......

Where did you make this device that pulls hair and detonates it?

"Don't worry, don't worry!"

Zhang Ran hurriedly comforted: "Everything is difficult at the beginning, and there will definitely be a lot of problems at the beginning, let's study it together and overcome it slowly - just like this grenade, let's separate all the problems and overcome them one by one!" ”

Speaking of this, Zhang Ran asked Wang Lao to call the cow and overcome the difficulty of the grenade shell first.

As for pulling the hair to start the fire.

Zhang Ran thought of the kind of matches he had seen in Westerns before, which could be ignited anywhere, and he also knew the general process, which was nothing more than a small amount of white phosphorus and yellow phosphorus mixed with a wax layer on the surface, if it was designed, it might not be able to be used on grenades.

It's just that it's so unsafe, let alone a grenade.

So he wanted to wait, wait until he went out to find a grenade and came back, and then let the rough drill study it.

After all, even he, a person who has experienced the information explosion, is a little confused, and it is really a bit difficult for people to make Mao Drill, who is doing artillery battles, think about it blindly.

Niu Da just came for a day, was Zhang Ran found several times, and he wanted to repair the gun and participate in the development of the grenade, which fully felt the heavy pressure on his shoulders, so he was enthusiastic, saying that he would resolutely obey the instructions of the chief and must complete the task.

At present, this can still make the villagers in the base area give some broken copper or iron, what can be done later?

The villagers don't have iron ore at home!

Wang Laogui and the others also looked at Zhang Ran in unison, obviously they were also worried about this.

"Look at you, what are you worried about-do you know that we are the Eighth Route Army?"

Zhang Ran raised his chin and hummed, "Do you know what is sung in the song?" There was no food, no clothing, and the enemy sent forward...... No guns, no cannons, little devils make them for us! ”

"This song is interesting, captain, you teach us!"

"Captain, that little devil has food and clothing, guns and cannons for us, so what are we going to toss?"

The focus of a group of people is completely different, and they have forgotten that they were still worried about the lack of iron a second ago.

", get serious!"

Zhang Ran glared at this group of guys who were thinking too much angrily, and continued to squat down and discuss the matter of this grenade body with Niu Damaozhuan, it can't be just a pimple, there must be a cutting division on the top, so that more shrapnel can be produced when it explodes.

"This is easy to do, when the time comes, when the bomb is made, I will just knock it with a chisel when it is red!"

Niu Da was full of confidence in this, saying that he and his father did this when they opened a blacksmith shop in the county, and how big the iron was, it was all broken by such a chisel that burned red.

Zhang Ran was speechless, and said in his heart that these two can be knocked with a chisel, of course, but this grenade is a consumable, and a battle may have to consume dozens or hundreds.

Of course, he won't say this, after all, it really affects the enthusiasm of the team.

"I don't know if the news given by these landlords Ma Chengbang will work, if it works, maybe I can get a batch of machinery back, then it would be good!"

Zhang Ran thought about it, and after explaining everything he knew, he went down the mountain - this trip out, no one by one, he couldn't come back at all, he had to arrange the work arrangements for this period of time first, there were many things!

"It seems that this official is not easy to be a ......"

When leaving, Wang Laogui and the others looked at the hair drill that was pulling their hair while discussing with Niu Da, and sighed.
