"There is nothing to say about the training of soldiers by Chief Yang." Chen Jianxiong exclaimed sincerely: "My one is even pulled out, which is impressive! In the future, please ask Chief Yang to help. We all need this instructor, weapons and equipment."

Yang Tianfeng breathed a sigh of relief and said, "There are not many spoils seized this time, but there are also a few good fun things. Brother Chen and his wife will pick a few, and Ge Dalongtou will also offer gifts for us to express our gratitude."

"Then thank you, Chief Yang." Ge Yinghua didn't want to ask for anything, but felt that he was very upright with Yang Tianfeng.

Now they are all enemies of the Japanese. If Gong Shan does not surrender, he will also be a helper for the advance team in northern Anhui. Yang Tianfeng sees this for a long time.

The matter was successfully resolved, and neither side was dissatisfied. Jiang Laowu immediately sent a team of 100 people, and then brought a few big old people to Wangjiazhuang to take over the territory, and then posted a post saying that it was reasonable to kill the big guys, and this matter was considered to have fallen into the ground.

Yang Tianfeng and Gong Shan both benefited from this matter. Yang Tianfeng blew up a lot of gold, silver and wealth. Gong Shan got the people, guns, territory and part of the property. Everyone was happy, and no one was dissatisfied.

At this time, although Yang Tianfeng and his troops were safe, they did not dare to take it too lightly. They had to be careful when they got along with the characters in the martial arts world. After all, this was on their territory. So, after a brief rest, Yang Tianfeng led the team to continue setting off, only letting Gongshan send some people as guides.

The next road was much smoother, and the big guys had already spread. As the two most powerful armed forces, Gongshan and Gongshan were quite powerful in alliance. Who would dare to feel uncomfortable? Not only did they dare not provoke, but the complicated armed forces were very respectful, for fear of offending them and ending up like big guys.

A day later, the troops led by Yang Tianfeng finally met with Chen Dalong's troops who came to pick him up. Now it is completely safe.

Not only was Yang Tianfeng relieved, but Liao Wenzhong and Ma Yuming were also very happy. The chips for promotion and wealth were finally secured. The next step was easier. The route had been arranged long ago. A living Japanese general was transported to the rear. It was unimaginable what kind of sensation it would be!

"Boom!" The gravel flew across the open space, dust flew, and a smog of smoke rose.

Yang Tianfeng and others walked out of the cover, came to the crater, and carefully observed the effect of the explosion. Then, they gave their thumbs up at the middle-aged man wearing glasses and the unshaven guy.

Hehe, the middle-aged man scratched his head a little embarrassedly. The hair of the tent seemed to have not been washed for a long time, and a lot of dandruff and dust fell.

The research people are all like this, ungrateful and sloppy. Yang Tianfeng didn't have much disgust. Talents are not about appearance, but about ability. These two people can give up the idea of ​​getting rid of the rear and stay in the occupied areas to work for the War of Resistance. They deserve his respect.

"The explosives made by Mr. Sun are powerful, and the mines made by Mr. Zheng are sophisticated and agile, and they are really powerful." Yang Tianfeng praised, and took out the drawings and handed them over.

The purpose of landmines is not only to eliminate the enemy. Even micro mines can make the enemy lose the ability to continue fighting. Each wounded must have several people to rescue, escort and take care of. When the enemy's wounded reaches a certain number, the enemy's logistics and medical institutions will be overwhelmed, and it can also cause serious psychological pressure to other enemy troops, thereby achieving the effect of dismantling the enemy.

The drawings Yang Tianfeng took out are a kind of micro landmine, also called bullet thunder.

Bullet thunder, as the name suggests, is a simple trigger thunder made of ordinary bullets. Its structure is simple, small in size, diverse in form and low in cost. It only requires one or more ordinary bullets (rifle bullets, pistol bullets) and ordinary materials such as iron nails, rubber bands, can boxes, wooden boards, etc. Even bullets can be made with recharged bullets, and the warheads can be made in a crude way.

Although this kind of micro landmine cannot kill the enemy, foot injury will affect the enemy's ability to move, and it also requires support and care from others, which directly affects combat effectiveness. If it is a reconnaissance operation, this bullet mine can make the operation fail. Although it is a small bullet, it can often achieve unexpected tactical effects when used properly.

What Yang Tianfeng made was such a simple thing, some things like children playing house, such as nails, bullets, soil, and wooden boards, but they couldn't be tested on site. You can't give up who has the soles of your feet and go through a hole, right?

"Sir, I understand what you mean." Zheng Ran, who was full of stubble, was a mechanical person. After looking at the drawings, he understood the principle, "Did the Japanese step on it, fire bullets, and injured his feet?"

"Yes, yes, that's what it means." Yang Tianfeng nodded repeatedly and smiled: "It's indeed an expert, you can understand it at a glance. I want you to think about it and create a large number of finished products for the soldiers to use, saving time and effort."

Bullet thunder was born in the smoke of World War II. Germany, Britain and the Soviet Union all produced such micro landmines. But now, at least in China, it has not yet appeared officially. Of course, knowing the principle, it is no longer a difficult task for professionals. Even using nails, wood and other materials can be made into copycat versions.

Zheng Ran looked at the drawing and said, "This drawing is already very detailed. Part of it is the shell and the inside is hollow. It is similar to the firing structure of a gun. It can be equipped with a firing needle, a firing needle spring and a simple safety; the other part is a bullet. As long as the raw materials are sufficient, I don't think it's a problem."

"That's all the hard work." Although there is a big difference between the bullet thunders created and those produced in real industrial production, Yang Tianfeng still gave a thumbs up again in admiration.

It has been several days since Yang Tianfeng and the others came back. After a simple rest, he became busy again. With Mr. Sun, a chemistry expert, he wanted to build an explosives workshop; as for landmines, there is no way to use black gunpowder, only new explosives can attack the Japanese more effectively; with Mr. Zheng, some of his wonderful ideas (all plagiarized items from later generations) can be turned into real objects faster.

"I'll get it out as soon as possible." Zheng Ran replied briefly. Only when it comes to professional issues can he talk more. He is usually a taciturn person.

"By the way, I have to trouble you to produce some mines whose shells are not metal." Yang Tianfeng bent down and picked up a shrapnel from the ground, fiddled with them for a while, and said thoughtfully: "If those who use ceramics and glass do not know whether they can do it, the Japanese mine detectors are powerless, right?"

Mr. Sun and Zheng Ran looked at each other and nodded at the same time. Although Chief Yang is young, he is very meticulous. Although he doesn't meet much, Yang Tianfeng's respect for them and his deeds of winning a great victory just after entering the enemy's backbone still made them feel that the trip was worth it.

"This is easy. Porcelain bottles and pottery jars can be used. If not enough, small earth kilns can also be fired." Mr. Sun pushed his glasses and said, "Sir Yang, what else do you have to ask?"

"There are many requirements!" Yang Tianfeng smiled and said, "But the meal must be eaten one by one! You don't have to worry, study it slowly and improve it gradually. The equipment in the arsenal needs to be added and the raw materials need to be collected. In the future, it will be the time for you to show off your skills!" After saying that, he smiled and reached out to make up for the invitation gesture, "I'll do my job, let's go for a big meal, which is to make up for the welcoming banquet I owe."

Wine is the lubricant for men to get along with each other. When talking about things at the table, it often seems more harmonious and harmonious. Although Sun Boyan and Zheng Ran are not good at drinking, Yang Tianfeng does not have to stop drunk.

The two experts have a good impression of Yang Tianfeng. They are young, energetic, refreshing, and less frivolous as young people. They arrange things very meticulously and meticulously. Moreover, this chief seems to have a wide range of knowledge, and can even speak well in terms of machinery, chemistry, etc.

Although it was not for the sake of a comfortable life and shallow benefits such as money, Yang Tianfeng tried his best to give the two experts the best treatment based on the concept of later generations.

We talked while eating and talking, and we talked about weapons without realizing it. At this time, anti-Japanese war was the theme, so it was easy to turn it on. From landmines, bullet mines, heavy mortars, and the advantages and disadvantages of guns, detailed isolation of arsenals, as well as some problems of using assembly line production.

Yang Tianfeng suddenly patted his head, remembered something, and said, "Mr. Sun, Mr. Zheng, have you heard of silencers or reducers?"

"Silencer? Reducer?" Mr. Sun shook his head gently.

Zheng Ran guessed, "Listen to the meaning of this word, is it something that eliminates sound or weakens sound."

"Yes, that's what's the thing." Yang Tianfeng further explained: "Put it on the muzzle, and the sound made when shooting is very small, making it difficult for the enemy to detect it."

Sun Boyan shook his head gently, looked at Zheng Ran, and said, "You have stayed to study, have you heard of this?"

Zheng Ran scratched his hair again, and some fine things fell down one after another. Yang Tianfeng immediately decided not to pick up the dishes in front of him.

"When I was in the United States, I heard that poachers seemed to have such a thing that could make gunshots smaller so as not to be discovered." Zheng Ran said thoughtfully: "But I have never seen a physical object. I'm afraid it's not that easy to create it."

"This is not urgent. It's better to build it, but it doesn't matter if it can't be made." Yang Tianfeng waved his hand, signaling that he didn't care, and said instead: "Mr. Zheng, have you seen that anti-aircraft machine gun? If it is modified, can you fire grenades?"
Chapter completed!
