Su Xin's third factory has been moved into a cave. In the middle and lower part of the mountain, the outer cave is more than 100 square meters and more than five meters high. There are more than a dozen caves of different sizes extending inward.
The cave is open, dry, strong, and can especially be used for air defense. It is indeed very suitable for a new factory.
Su Xin divided these caves into several workshops, which are used for repairing firearms, assembling bullets, 50 cannons, etc. Each workshop has a decent name engraved on it.
While introducing Wang Xuexin, she joked: "Xiao Wang, let's see, it won't be long before there will be another mine jumping workshop!"
"It sounds like you are being wronged!" Wang Xuexin looked at the cave inside and out and said, "If you are not happy, at worst I won't come up with any ideas in the future!"
"Who wouldn't be happy?" Su Xin responded quickly: "There are still a lot of empty holes here, so I'm worried that you don't have enough ideas!"
If Xiao Dongbei really didn't say anything, Su Xin would definitely be criticized by the factory director for this matter.
"That's ridiculous!" Wang Xuexin replied nonchalantly: "I haven't asked you for payment yet, but you're still complaining!"
"What are you looking at?" Su Xin asked a little strangely when she saw Wang Xuexin acting like that.
Wang Xuexin said "Oh" and explained: "Nothing, it's just an occupational disease. I'm... used to fighting. When I come up, I just look at the terrain and defense."
Wang Xuexin felt that he was worrying too much. At this time, it was not easy for the Japanese to attack Lujiagou.
"But I am talking about Xiao Su!" Wang Xuexin said: "There are not enough holes to cover each other, and it is easy to be blocked by the enemy!"
"Are you still worried about this?" Su Xin sighed inwardly, this little Northeastern man had to fight many battles and endure many hardships to have such a habit.
After a while, Su Xin asked intentionally or unintentionally: "By the way, didn't you say you wanted to save money to build a house and marry a wife? I'll give you a room in my cave!"
Wang Xuexin burst out laughing: "Classmate Xiao Su, are you taking it seriously! Aren't I dealing with the factory director? If he continues talking like this, won't he have to start saying that this girl is good and that girl can do something?
Something like that!”
Su Xin felt secretly happy and summoned up the courage to ask: "Then you..."
At this moment, Hardware and Zhang Ruozhong came up carrying a box of parts.
These parts could have been brought up on a conveyor belt, but because they were worried that they would not be found among other parts, they were simply carried up.
As soon as Hardware entered the cave, he shouted excitedly: "Director Su, Xiao Dongbei, the parts are complete, let's pretend to try it!"
What is assembled is what Wang Xuexin calls a jumping thunder.
Jump mines had actually come out at this time. The first type of jump mine was the S-type jump mine called "Bounce Betty". It was put into production in 1935 and used in the World War in 1939. After that, various countries imitated it one after another.
It's just that information in China is relatively closed at this time... In fact, it was the Japanese who blocked the coastline, so we don't know about this kind of mines yet.
However, what Wang Xuexin imitated was not this S-shaped jumping mine...the delay fuse of this kind of jumping mine is still somewhat technically difficult.
Although it is not very difficult, it is enough to stump Zhang Wan and his group.
Su Xin frowned and said: "Although we can also make a delay fuse, the time is not precise enough, especially a delay fuse that requires explosion within one second!"
Zhang Wanhe nodded and said: "If the delay is too long, the mine will fall to the ground. If the delay is too short, it will explode in the ground. In both cases, it will not have much effect. In addition, each mine will
Isn’t the cost too high for a time-delay fuze?”
Su Xin added: "There is a cheap time delay that relies on gunpowder burning like a hand grenade, but its accuracy is worse."
For countries with mature industries such as Europe and the United States, some things are cheap, simple, and can be mass-produced. But for the Eighth Route Army, which has almost no industrial foundation, they are expensive, difficult, and all made by hand.
Inaccurate and unsafe.
So the production of jumping mines got stuck here, and Zhang Wanhe and others were even considering giving up on jumping mines because of low cost performance.
This is how Zhang Wanhe explained to Wang Xuexin: "Xiao Dongbei, your idea is very good, but landmines need to be mass-produced to be useful. If the output is only a few dozen a day... no matter how good the landmines are, they are just a showpiece."
ah!"
Wang Xuexin took a look at the sketch drawn by Zhang Wanhe and said: "This is not easy. What kind of delay fuse do you need? Take a steel wire, tie one end to the bottom and the other to the mine body. When the mine body is thrown up, pull it like this
...Isn’t this going to explode? Just make the wire as long as you want to blast it as high as you want to ensure accuracy!”
Su Xin: "You monster!"
Hardware: "Can you give me some way to survive?"
Zhang Wanhe: "Is this fucking human?"
…
People are more annoying than others!
This discussion went on and on, and it was almost rejected, but the result was a tightrope?
This made Zhang Wanhe feel that he couldn't save his face. He whispered to Su Xin and other directors: "Why don't you all have the cleverness of Xiao Dongbei? There is also an arsenal. If this spreads,
Isn’t it embarrassing?”
In fact, this is not Xiao Dongbei's cleverness, it is Mao Xiong's creativity... While other countries either used delayed fuses or delayed gunpowder, Mao Xiong pioneered the o3m-72 jumper with a steel wire.
thunder.
The characteristic of Mao Xiong equipment is that it is cheap and easy to use. Of course Wang Xuexin has to learn more.
Just when Su Xin and the hardware were assembling, Zhang Wanhe arrived belatedly.
He ignored the others, but pulled Wang Xuexin aside and asked: "Comrade Wang Xuexin, I am thinking about a problem. After we develop this mine and use it on the battlefield, the Japanese will definitely know about it. Then..."
Needless to say, will the Japanese produce more jumping mines and use them on the Eighth Route Army? Will the Eighth Route Army suffer the consequences? After all, the Eighth Route Army has more troops.
Wang Xuexin has actually considered this issue for a long time.
At this time, he smiled and replied: "Director, landmines are more useful for the defensive side. The Japanese are more for attacking, mopping up, and looting everywhere. They should be more afraid of this kind of landmines, right?"
"
Zhang Wanhe said "Oh", nodded and no longer had any scruples.
Wang Xuexin actually has another consideration: Jumping mines have been on the battlefield for several years, and are still used by allies of the Japs. If the Japs want this technology, they can easily get it.
The reason why the Japs didn't use it was probably because they had the same idea as Zhang Wanhe... If such a simple thing that can kill infantry on a large scale was learned by the enemy, it would not be a good thing for the imperial army!
So the problem becomes simple.
Whatever the enemy is worried about, the Eighth Route Army will use it.
