Zhang Wanhe reported to the leader and immediately organized a copy of the "ghost cannon".

First, we asked for a "ghost cannon" from the main force, and then we dismantled it into parts and copied them one by one.

This is simple to say but not easy to do.

Because of military industry, its components are usually as simple as possible. Only in this way can we minimize weight and enhance maneuverability and off-road performance.

Therefore, mature artillery like the "Ghost Cannon" can almost be said to have its use for every screw, and it cannot be more or less. Otherwise, there will be problems such as this and that in actual combat.

If you can maintain a fighter like the third brother, you can have an extra screw, and you are so envious that you think it's okay, but if you lose the extra ones, you can't see others. Then it would be strange if you don't fall the plane.

Therefore, this work is that every thing that is removed must be recorded in detail, and even a structural diagram must be drawn to ensure that it can be installed after being removed and that each part is in its position.

At this time, Zhang Wanhe found that Su Xin was still in trouble, so he had to call her back.

Su Xin did not disappoint Zhang Wanhe. She first split the "Ghost Cannon" into 8 parts, numbered these 8 parts separately, and then disassembled them downwards. Then she made detailed numbers, drawings and measurements for each part.

The reason for measurement is that some parts are very similar and have only subtle differences. They must be measured and recorded to distinguish them.

In the end, it was dismantled into more than 120 parts.

Su Xin was not relieved, so she installed the "ghost cannon" in the structural diagram. After firing a shell, she was fine before she could make the part clear.

It is not too difficult to build other parts, mainly because it is the issue of determining the size and specifications.

The hardest thing is the gun barrel.

First of all, it is not easy to get the train wheel axle. Although it is a common thing in enemy-occupied areas, the base area is far away from the traffic lines and even cars are not common, let alone trains.

However, Zhang Wanhe does not need to consider this issue. He only needs to talk to the chief and arrange the task immediately at the headquarters and let the local troops find a way to solve it.

In the end, the workers in the repair factory stole three out.

They used the method of stealing the slaughtered beams and changing columns with inferior products, that is, they stole the scrapped axles first as scrap iron refining... It is much easier to steal scrapped axles, and no one will carefully count the scrap iron.

Then use this defective wheel axle to replace the good wheel axle.

It is safe to do this, and it will not expose your identity, but can also steal it for a long time. One day, even if there is a problem with the axle, it will only be considered as a result of natural loss.

Then, he used various channels to smuggle out of the city first, and then transferred to the Eighth Route Army one by one.

These workers usually do such things, so they are familiar with it. Not long after, the headquarters received a reply. The three axles were already on the road and will continue to be supplied in the future.

When Su Xin talked to Wang Xuexin about the latest progress that day, she frowned and said, "There is no major problem with the wheel axle. In addition, we plan to use the used drill pipes used to make a twist drill for drilling holes for the wheel axle."

Wang Xuexin nodded in agreement.

Twist diamonds are the most traditional, direct and simplest way to punch holes in the United States, which are to use a drill bit like a twist.

The drill rod used for coal mines originally had the large shape of a twist drill, and as long as it is slightly improved, it can be transformed into a twist drill for making a gun hole.

Su Xin said: "We are doing the work of making twist drills. We need to heat them for a long time. After the process is released, we have to return to the furnace to heat them soon, so the process is very slow."

Wang Xuexin asked: "Is the furnace temperature not high enough?"

"It can be said that." Su Xin replied: "To be precise, it should be that the human-powered bellows are not efficient and the firepower is uneven."

Wang Xuexin looked at Su Xin in disbelief: "Why don't we fix a high-efficiency mechanical bellows ourselves?"

Su Xin gave Wang Xuexin a blank look and replied, "Where are we going to find a mechanical bellows? Xiao Wang? Who can't talk?"

"Zhaojiayu!" Wang Xuexin said: "We surrounded dozens of Japanese cars not long ago! Although most of these cars were broken and could not move, not every car was broken, right? If you look for it, there will always be several useful engines. With the engine, isn't it easy for mechanical bellows?"

Su Xin was stunned when she came, and then said, "I, I have to talk to the factory manager!"

He turned around and ran away.

On the way, Su Xin didn't know how to evaluate Xiaobeidong.

What he said was not a profound problem, nor did he need to learn it in school, but others just couldn't imagine it.

For example, using train wheel axles to build cannons, and using car engines to modify bellows... Then gasoline is also delivered!

After running to Zhang Wanhe, Zhang Wanhe called the Hundred Battles Group currently stationed in Zhaojiayu without saying a word:

"Captain Li? I am Zhang Wanhe!"

"Are the wreckage of the car surrounded by the Independence Group some time ago still there?"

"That's good, that's good...I hope you can protect those cars and I'll pick something useful!"

"Yes, yes! Thank you very much!"

After hanging up the phone, Zhang Wanhe said to Su Xin: "Look, I'm right! Xiaobeidong has solved another big problem for us! Once this mechanical bellows are tidied up, it is not just a problem of twist drills, but the production of other parts has also accelerated!"

Just when Zhang Wanhe was so happy that he could not stop talking, he heard Li Yunlong shouting outside: "Old Zhang, Lao Zhang?"

Zhang Wanhe said "Ouch" and lowered his voice and explained to Su Xin: "You can't let him know about Xiaodongbei's helping us build artillery!"

Before he finished speaking, Li Yunlong had already stepped into the door.

"Oh, Lao Zhang." Li Yunlong said with a smile: "Long time no see, your Lao Zhang is getting more and more energetic!"

Zhang Wanhe pretended to have taken a form and wrote something on it, then looked up: "Old Li, I'm busy now, let's talk about it another day if you have something to do..."

"Don't be anxious!" Li Yunlong raised his head: "I'm guessing that Xiaodongbei's injury has almost healed. Today I'm here to pick up people, so I'll see you, your old comrade. Since you're busy, I'll..."

"Wait a minute!" Zhang Wanhe put down his pen and stood up on the spot: "This little Northeast has not yet been fully recovered. Wouldn't you stay for a few more days?"

"Hey!" Li Yunlong said with a smile: "Look, this organization takes care of him more. It is a single ward and has delicious food and drinks. Your old Zhang also asks Director Su to take care of him every day! Why am I so embarrassed?"

After hearing this, Zhang Wanhe understood in his heart. It turned out that Li Yunlong knew everything, and he came to collect debts from the door.
