Zhang Wanhe immediately organized the imitation work of the "ghost cannon" after reporting it to the chief.

First, a "ghost cannon" was obtained from the main force, and then it was dismantled into parts and copied one by one.

This is easy to say but not easy to do at all.

Because in military industry, its components are usually required to be as streamlined as possible. Only in this way can the weight be reduced to the maximum extent and the maneuverability and off-road performance can be enhanced.

Therefore, for mature artillery like the "Ghost Cannon", it can be said that almost every screw has its use, no more and no less, otherwise problems of this kind are likely to occur in actual combat.

If everyone maintains fighter jets like the third brother and can get an extra screw, and is so arrogant that he thinks it's fine and just throws away the extra one so that others can't see it, then it would be weird not to crash the plane.

Therefore, this job requires detailed records of every item that is disassembled, and even structural diagrams must be drawn to ensure that it can still be installed after disassembly and that every part is in its proper position.

At this time, Zhang Wanhe realized that Su Xin was still there, so he had no choice but to call her back.

Su Xin did not disappoint Zhang Wanhe. She first split the "Ghost Cannon" into 8 major parts, numbered the 8 parts separately, and then disassembled each part. Then she numbered each part in detail.

Drawing and surveying.

The reason for measuring is because some parts are very similar with only slight differences, so they must be measured and recorded for differentiation.

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

Su Xin was still uneasy, so she installed the "ghost cannon" according to the structural diagram. After firing a cannonball and it was no problem, she finally found the parts.

The other parts are not too difficult to make, the main problem is determining the size and specifications.

The difficulty is the barrel.

First of all, it is not easy to get train axles. Although they are very common 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 did not need to consider this issue. He only needed to tell the chief, and the headquarters would immediately arrange the task and let the local troops find a way to deal with it.

Finally, workers in the maintenance factory stole three of them.

They used shoddy methods to steal goods and replace them with shoddy goods, that is, they stole the wheel axles that were scrapped and were to be resmelted as scrap iron... It was much easier to steal the scrap wheel axles. No one would carefully count the scrap iron.

.

Then replace the good wheel axle with the defective wheel axle.

It's safe this way, as it won't expose your identity, and you can still steal it for a long time. One day, even if there is a problem with the wheel axle, it will only be considered to be caused by natural wear and tear.

Then, they used various channels to smuggle them out of the city, and then transferred them to the Eighth Route Army station by station.

These workers often do this kind of thing, so they are familiar with it. It didn't take long for the headquarters to get a reply. The three axles were already on the way, and they would 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 big problem with the wheel axle. In addition, we plan to use the waste drill pipes used in coal mines to make twist drills to drill holes for the wheel axle."

Wang Xuexin nodded in agreement.

The twist drill is the most traditional, direct and simple way to drill holes invented in the United States. It is to drill hard with a twist-like drill bit.

The drill pipe used for drilling coal mines originally has the large shape of a twist drill. As long as it is slightly improved, it can be transformed into a twist drill for blasting holes.

Su Xin said: "We are currently making twist drills. We need to heat them for a long time, and they have to be reheated shortly after being processed, so the process is very slow."

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

"You can say that." Su Xin replied: "To be precise, it should be that the efficiency of manpower pulling the bellows is not high, and the firepower is uneven."

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

Su Xin rolled her eyes at Wang Xuexin and replied: "Where can we find a mechanical bellows, classmate Xiao Wang? Who doesn't know how to talk?"

"Zhaojiayu!" Wang Xuexin said: "Not long ago, we surrounded dozens of Japanese cars! Although most of these cars were damaged and could not be moved, not every car was damaged. You go

If you look for it, there will always be a few useful engines. Once you have the engine, isn't it easy to mechanically build the bellows?"

Su Xin was stunned at this, and then said: "I, I have to go and talk to the factory director!"

Saying that, he turned around and ran away.

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

What he talked about was not a profound question, nor did it need to be learned in school, but other people just couldn't think of it.

For example, you can use train axles to make cannons, or you can use car engines to modify windboxes... and you also get gasoline!

As soon as Zhang Wanhe went to talk to him, Zhang Wanhe made a call to the Baizhan Regiment currently stationed in Zhaojiayu without saying anything:

"Captain Li? I am Zhang Wanhe!"

"Are the car wrecks that were surrounded by the independent group some time ago still there?"

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

"Yes, yes! Thank you very much!"

After hanging up the phone, Zhang Wanhe said to Su Xin: "Look, what I said is right! Xiaodongbei has solved another big problem for us! This mechanical bellows is not just a problem with twist drills, but also production

Other parts are also speeding up!"

Just when Zhang Wanhe was grinning from ear to ear, he heard Li Yunlong shouting outside: "Old Zhang, Old Zhang?"

Zhang Wanhe said "Ouch" and lowered his voice to Su Xin: "We can't let him know about Xiao Dongbei helping us build cannons!"

Before he finished speaking, he saw Li Yunlong walking through the door.

"Hey, Lao Zhang." Li Yunlong said with a smile: "Long time no see, you, Lao Zhang, are getting more and more energetic!"

Zhang Wanhe pretended to take a form and write something on it, then raised his head: "Old Li, I'm busy right now. If anything happens, let's talk about it another day..."

"No hurry, no hurry!" Li Yunlong raised his head: "I don't think Xiao Dongbei's injury is almost healed. I'm here to pick someone up today. I stopped by to see your old comrade. Since you are busy

Yes, then I will..."

"Wait a minute!" Zhang Wanhe put down his pen on the spot and stood up: "This little Northeast is not healed yet, why don't you stay for a few more days?"

"Hey!" Li Yunlong said with a smile: "You see how much care the organization takes for him. It is a single ward and the food is delicious. You, Mr. Zhang, still let Director Su take care of him every day! How can I be embarrassed?

?”

After hearing this, Zhang Wanhe understood in his heart. It turned out that Li Yunlong knew everything and came to collect debts.
Chapter completed!
