The old and young returned to the laboratory and immediately started to work, the vigorous and resolute Wu Sixue was responsible for preparing the outline of research and development, and Huang He went to find Shan Wenbao, an otaku.

This irritable old brother is not moved by ordinary people, even if Zhang Wanhe comes, he is likely to touch his nose. After all, he is still a little worried about the simple wind tunnel.

After seeing that all the main R&D forces had arrived, Wu Lao walked to a blackboard on crutches.

There is a hand-drawn structural diagram of the Type 92 infantry gun, and it can be seen from the detailed notes everywhere that the owner of the drawing must have spent a lot of effort.

Originally, Wu Sixue wanted to imitate the devil's Type 92 infantry gun, but after Huang He learned about this idea, he immediately persuaded the other party.

In addition to the ones that are currently being unlocked, the next decision can be made to unlock the various guns of the Gallic chicken.

From small-caliber anti-aircraft guns and anti-tank guns to large-caliber 155 heavy grenades, who will be able to look at the devil's 70-mm water pipe at that time.

Wu Lao is not old-fashioned, and after learning that there are good things, he put away the idea of imitation.

But this drawing was still preserved, and he planned to select some talented comrades in the military industrial area, so that the mechanics could get in touch with the structure and manufacturing process of the artillery in advance.

Now with the task of the brigade commander, this drawing has a new purpose.

"The structure of this Type 92 infantry gun is relatively simple compared to the barrel guns on the European battlefield. It has more than 120 parts all over its body, and it is not difficult to manufacture or imitate. ”

When he said this, the old man also stared at Huang He, who was sitting in front of him pretending to be a good baby, and he continued with a wording:

"And the problem we are facing this time is not big, we only need to solve the barrel."

"Who of you two knows, with the current conditions of the logistics department in the base area, where is the difficulty in building a cannon barrel?"

Wu Lao, who has studied abroad for most of his life, wants to do the most after returning to the base area is to impart the knowledge he has mastered to all comrades who are eager to learn.

For half a month, the old man gave classes to the technical backbone of the military industrial zone almost every day.

Because the comrades over there have a poor foundation, this has made him develop the habit of coaxing children to teach, and when he doesn't lose his temper, he looks like an old teacher with rich teaching experience.

But neither Huang He nor Shan Wenbao showed a trace of impatience, and every selfless scientist deserves respect.

After hearing this question, the two looked at each other. Seeing Shan Wenbao's crazy eyes for fear of trouble, Huang He finally answered the question.

"The first difficulty is rifling, we don't have the conditions to engrave here, and it will take a lot of time if you do it by hand. Even if you teach this craft, the first batch of apprentices will not be able to teach until next year. ”

"The second difficulty is the cannon steel, if we use the toughening technology we have now, the strength of the cannon barrel will definitely not be enough."

"Even if you can barely make it, it's just a consumable, and when the time comes, the commanders on the front line will definitely scold your mother again."

The toughening techniques in the mouth of the Yellow River refer to: the black-hearted toughening on the side of the ugly country and the white-hearted toughening on the side of Sandezi.

As an old man who has traveled from south to north, Wu Lao is naturally proficient in these skills. The reason why these two technologies are preferred for promotion is to increase the production capacity of artillery shells in the military industrial area of the Logistics Department.

Although the Yellow River can provide a certain number of various types of artillery shells every month, the number is limited by the output of the military factories in the system.

Even though the two newly established firearms factories have been systematically recognized, there are still only five munitions factories.

Because there is still a big gap in the basic infantry equipment of the Eighth Route Army, artillery shells can only be provided in small quantities.

At present, the base area mainly uses white pig iron, which is brittle and hard, and the shells cast from it do not meet the minimum requirements for turning.

However, once these locally refined white pig iron are toughened, the production of shells will undergo earth-shattering changes.

Not only can the processing performance be improved, but the output of shells can be greatly increased. Moreover, the quality of the weapons was strengthened, so that the self-produced shells were further adapted to the needs of the front.

Once the military factories can increase the production of artillery shells, it will share some of the pressure for the Yellow River.

However, there has been good news in recent times.

Under the leadership of the deputy director, the first production lines of MAS-36 and FM-24/29 have been successfully developed.

Although because the technology is not mature enough, a very small number of firearms have a certain failure rate when they are used, resulting in the newly established firearms factory has not been recognized by the system.

However, Huang He believes that the comrades in the rear will continue to make progress and will one day pass the systematic quality inspection. What's more, being able to produce its own weapons is of great significance to the Eighth Route Army, and it is not too much to say that it is a shotgun for a gun.

Eight Ways of Magic! The future is promising!

After hearing Huang He's answer, Wu Sixue nodded with satisfaction, he was very satisfied with this young doctor.

"I can take care of the rifling part, just use a method similar to hook knife broaching. There is no reason why the descendants of our ancient civilizations can't grasp the things of these indigenous metropolises in the Americas. ”

"The cannon body has also found a replacement, and I am going to replace it with the big shaft of the devil train. It was made of high-carbon steel, which was more than enough for a cannon barrel. ”

"It's a pity that the original shells can't be used, the new barrel caliber will definitely be larger, and the shells need to be redone."

After scientists reach the level of the Yellow River and Shan Wenbao, it often takes only a short time to judge the feasibility of a thing. Although they are not in their field of expertise, their knowledge is amazing.

What's more, as an engineer who studied in Gaul, Huang He is a person who has been in close contact with Miss 75. Although he didn't shoot a few shots himself, he knew that this famous rapid-fire cannon was made of high-carbon steel technology.

If the cannon body is cast with a large shaft, even if the life is average, it can solve the problem of starting from scratch.

The three of them discussed the idea for a few minutes, and after making sure that nothing was missing, they sent Wang Dexing to Zhang Wanhe to ask for it.

After all, the big axle of the devil's train is not easy to handle, and it is estimated that it will take another army to carry out an ambush to bring back the materials they need.

But this matter is not too troublesome, who let the Eighth Route Army often pick up the railway, and he is very clear about the movement of the devil train.

But less than half an hour passed, Wang Dexing ran back with a happy face, he pushed open the door of the laboratory and said excitedly:

"Director! The big shaft will be delivered right away! Prepare yourselves! It is estimated that there will be five minutes before the comrades arrive. ”

This result is true that the three of them are confused, and someone will send a pillow when they are really sleepy. But after all, this is the logistics department of the Eighth Route Army, and it is understandable that it is a bit of a mess.

After a while, Huang He saw a transport team come to the door of the laboratory, led by Zhang Wanhe, who he hadn't seen for a while.

As the saying goes, when a fellow sees a fellow, his eyes are full of tears.

Zhang Wanhe hugged Huang He's shoulder with a smile on his face and hammered it lightly, and he said with a little evil smile:

"I don't know how long I've been waiting for this day. In the past, you always used to get supplies for the logistics department, but this time it was finally my turn to perform. ”

"You can use these two big axes first, if they are not enough, you can send someone to find me, and we have four more in the warehouse."

"But it's a coincidence, some time ago, our workers behind enemy lines just destroyed a devil's factory and got some things on the train. As a result, I used it today, and you're in luck! ”

Hearing Zhang Wanhe's words, Huang He suddenly thought of the decision to passively unlock some time ago, but now it is inconvenient to check the system, so he can only give up temporarily.

"Lao Zhang, I won't say much if you thank you! We try to reduce losses the first time, so you can wait for our good news. ”

Zhang Wanhe and the others also knew that every second of time was precious, so they moved the train shaft into the laboratory and left.

After saying hello to Wu Lao and Shan Wenbao, Huang He returned to his room first, after all, he couldn't help with the work he had just started.

There was no one around, and the Yellow River opened the interface of the system. Not surprisingly, these train axles are really related to the last decision.

"The Pride of the Workers Behind Enemy Lines: 2/4 of the current progress

At present, in Jin Province, a civilian factory in Xiaori has been damaged and forced to stop production.

When the Yangquan Patrol held a birthday party for the captain, it was completely annihilated by the workers behind the enemy lines of the Eighth Route Army.

The plan to sabotage the Taiyuan Arsenal is underway, and the bombing of the bridge at the Huting stronghold is being planned."

Although he didn't know the specific situation, seeing that the devil had suffered a lot of losses, Huang He still waved his fist excitedly.

You all guessed the prototype of Wu Lao, and I specially strengthened it in the book
