As soon as Kong Dewen said the thought in his mind, Zhou Chengru thought of a gun and blurted out: "Shotgun!"

"What is a shotgun?" Kong Dewen hid for a moment.

Zhou Cheng then remembered that there was no special shotgun yet. As for the name of shotgun, it would not appear until the 1950s and then officially equip the troops.

I quickly explained: "The shotgun I'm talking about is similar to a more powerful musket."

"We have made the caliber bigger, and then made the separately loaded iron sand and gunpowder into shotguns, loaded and fired like rifles, and attacked the Japanese at close range."

Kong Dewen understood it, and after a moment of thinking, he showed an expression of agreement: "Captain, I think the name of shotgun is very appropriate. An ordinary rifle fires only one shot, and a shotgun fires more than a dozen, or even dozens of bullets, to strike the Japanese in a fan shape. If you seize the opportunity to shoot, the enemy is not prepared, and it is possible to hit ten Japanese in a shotgun hard."

"I think the new weapons we produce are called shotguns."

Zhou Cheng didn't expect Kong Dewen to react so quickly. He reacted as soon as he reminded him and immediately ordered: "Since we have a idea, let's find a few more people to come together to study and determine the caliber and ammunition of the shotgun, make two as soon as possible, and experiment with the power!"

"I don't hide it from you. It's ten days or half a month later. The Japanese army will launch a new round of attacks on our National Salvation Army."

"This offense will definitely be unprecedented. The shotgun we just said must participate in the battle, and it is our trump card to defeat the Japanese!"

Two days later, a shotgun that looked particularly rough was released.

In order to increase the charge and the killing area of ​​shotgun, the barrel has a caliber of thirty millimeters, which looks like a small cannon.

Compared with firearms, the production and manufacturing of ammunition is much simpler.

It is thicker than an ordinary bullet, with a pointed end turning into a round head, and there is almost no difference in other aspects.

In addition to the primer and launching medicine, the shell was filled with sixty four-mm projectiles.

The test site was not too far from the arsenal. When Zhou Cheng arrived with a shotgun, twenty targets were already placed forty meters in front of the shooting position.

The effective range that everyone estimates for the shotgun is fifty meters, and forty meters is its best shooting distance. If the projectiles shot out can hit most of the targets, it means that this earth-made shotgun completely meets all the requirements it puts forward and can produce and equip the troops on a large scale.

"boom……"

The dull gunshots were more like the sound of shelling to everyone's ears, and then a ball of white smoke was seen spraying out from the thick muzzle.

Before he could react, six or seven targets were knocked to the ground directly opposite him.

Zhou Cheng was very anxious. He rushed towards the target as soon as the gun rang, and then checked the bullet holes on it one by one.

Five minutes later, the result came out: all seven targets that were knocked down were hit by more than three projectiles. Two-thirds of the targets that were not knocked down were hit by the projectiles, and the remaining one-third of the targets were too far away from the center point of the target, and there were no projectiles, but Zhou Cheng was already very satisfied.

Reduce the targets that were not hit by the projectiles, the kill width of the shotgun has exceeded fifteen meters away, fully meeting its own requirements.

More importantly, after a flight of forty meters, the ammunition was still very fast, easily breaking through the pig skin hanging on the target in the arsenal.

They can even penetrate pig skin, and they will definitely easily penetrate the Japanese body.

The excited Zhou Cheng asked quickly: "Director Kong, is it difficult for the arsenal to produce this gun?"

Kong Dewen shook his head: "It's not difficult. The barrel diameter is three millimeters and the requirements for chamber pressure are not high. It is easier to cast than ordinary rifle barrels. It can basically be formed in one go. It can be used after a little polishing."

"And the shotgun is a smoothbore gun, and there is no need to carve the rifle, which saves another process compared to the rifle barrel."

"If we stop the production of ordinary rifle barrels and make every effort to produce shotgun barrels, it will definitely be fine if we have fifty ones a day."

"In addition, the shotgun is a single shot firearm. When one shot is fired and loaded with ammunition at one time, it has almost one-third fewer parts than ordinary rifles. As long as the arsenal produces it with all its barrels, I can build as many shotguns as I have!"

"Where is the ammunition?" Zhou Cheng continued to ask.

"It's not difficult!" Kong Dewen shook his head and replied.

"Although the gunpowder production team has not yet provided launching medicine and firing medicine, we have reserved a lot, and it should be no problem to produce 200 shotguns a day!"

Zhou Cheng was so happy that he almost jumped up from the ground, his face was filled with joy, and he was excitedly ordered: "Great, Director Kong, I asked the arsenal to produce 500 shotguns and 2,000 supporting ammunition within ten days. I will help you solve the raw materials you need, but you must complete the production task within the specified time!"

Kong Dewen was very confident in the production capacity of the arsenal and blurted out without thinking: "Report to the regiment commander, we have the raw materials for producing shotguns, so we can ensure that the task is completed on time!"

After hearing this, Zhou Cheng's smile became stronger and he continued to ask: "In addition to the shotgun, I also want you to help me build another weapon!"

"What weapon?" Kong Dewen asked immediately.

"Landmines!" Zhou Cheng replied.

Kong Dewen was very confident and answered in a big tone: "Captain, I can't guarantee other weapons and ammunition, so there will definitely be no problem in creating landmines."

"A little change of the process and mold of the grenade body can produce mine shells. It is definitely no problem to have two or three hundred a day."

"How many you want, Team Leader? If it's within one thousand, I promise to deliver it within five days."

"Director Kong, you must have understood it wrong!" Zhou Cheng quickly shook his head and explained: "The mine I want is not the kind of conventional mine you think!"

"The power of conventional mines is too small and very easy to be found by mine detectors."

"What I want are two very special landmines!"

Kong Dewen frowned immediately and asked very seriously: "What are your requests for the commander?"

"Let me talk about the first mine first, I call it a single mine!"

"Every time we fought guerrilla warfare with the Japanese and puppet troops, in order to slow down the pursuit of the Japanese and puppet troops, we would use grenades to lay some boasts on the roadside."

"But the power of grenades is limited, and there are many limitations in setting up tricks, which is a waste of time. I wonder if you can produce some small landmines carried by individual soldiers, which are both convenient to carry, and they are not only hidden from time or place. They do not need to take time to bury them, and they can be arranged in a few seconds."

Kong Dewen understood Zhou Cheng’s thoughts as soon as he heard this: “Captain, I understand what you mean!”

"The individual mine you want is actually similar to a grenade, but you don't need to install a delayed fuze, and it explodes after pulling the fire, and it's even more powerful!"

Zhou Cheng nodded immediately: "That's what it means, can the arsenal be produced!"

"Can..." Kong Dewen was very confident: "This kind of individual landmine does not require delayed fuzes or wooden handles. It should be easier to produce than grenades. Two hundred pieces a day will definitely be fine!"

Zhou Cheng immediately ordered: "Then let me produce a thousand individual mines first, the faster the better."

Seeing Kong Dewen taking notes his request, Zhou Cheng continued: "The second mine I want is a little bit complicated!"

"I thought of it only inspired by grenades."

"When the troops throw grenades, if they stay in their hands for three seconds before throwing them out, the grenades can explode in the air above the Japanese heads. The Japanese within a radius of three or four meters can be killed and injured even if they are lying down."

"I just thought of landmines. Because they were buried under the ground, the fragments flew into the sky after the explosion. Unless the Japanese stayed next to the mine, it would be difficult to be killed."

"If the mines can fly over the Japanese head and then explode, the fragments generated will fall from the sky, and they will definitely kill and injure all the Japanese and puppet troops within seven or eight meters of the surrounding area, and that will be powerful!"

"Although we don't have this kind of mine yet, I still gave it a name, bouncing mine!"

"After the landmine is trampled by the Japanese, jump up first, fly to the Japanese, and then explode."

Kong Dewen's eyes lit up when he heard it.

Whether it is the shotgun in front or the current bouncing mines, it looks simple and is not complicated to produce, but it lacks the idea of ​​thinking about such a weapon.

If it weren't for knowing that Zhou Cheng was the commander of the National Salvation Army, Kong Dewen would have left him in the arsenal.

For today's arsenals, there is no shortage of equipment and technology for the time being, but there are only wonderful ideas.

Zhou Cheng didn't know that his position in Kong Dewen's heart had reached another level, and he also had an additional identity as a military expert.

When I saw him excited and disappointed for a while, I immediately showed a worried expression: "Director Kong, is it difficult?"

"No difficulty!" Kong Dewen shook his head quickly!

"I was so excited. I felt that the idea you put forward by the leader is so good, and it completely subverted my understanding of landmines."

"We only need to add a delayed fuze to make the mine fly into the sky and then explode. As long as we control the time of the delayed fuze and test it a few more times, we will definitely achieve the goal."

"It's not difficult to throw a mine into the sky. We can add a base similar to a barrel to the mine, and put some launching medicine in the base. When the Japanese step on the mine, they will detonate the launching medicine and push the mine into the sky through air pressure."

"I just thought about it. Nothing else is difficult. The most difficult thing is to produce a base like a barrel for landmines. With the current strength of the arsenal, you can produce twenty ones a day!"

Zhou Chengchang breathed a sigh of relief and immediately ordered: "Enough, in addition to the shotgun and supporting ammunition just now, you will also produce 200 bounce mines and 1,500 and individual mines for me in ten days. The production of other ammunition can be temporarily stopped, and all the urgently needed weapons and ammunition in the production group will be concentrated to complete the production task within the specified time."
