Traveling through the sword to engage in military industry.

Chapter 63: Engineering Emperor Li Yunlong (Subscription Request)
This miraculous deal was actually made remotely.

Neither Ren Zhong nor Hu Rentao realized that there are still people as upright as the other in society today.

There is basically no bargaining.

Without even having a video chat online, the two of them believed each other.

So, when they exchanged more contact information and messages, Ren Zhong discovered that Hu Rentao was actually an associate professor specializing in steel!

Hu Rentao felt at ease after receiving the down payment, and both parties were very satisfied with this cooperation.

Ren Zhong asked Professor Hu about some things he didn't understand about the traditional blast furnace. Professor Hu then realized that Ren Zhong was serious and was really going to use super outdated technology to do something in a foreign country. In Professor Hu's view, such technology was full of problems, and he couldn't help but optimize Ren Zhong's traditional blast furnace to make it more reasonable and efficient.

With the help of a professional like him, the original 5 cubic meters of primitive blast furnace was expanded to about 15 cubic meters. Of course, it could not be larger. This kind of purely hand-operated primitive blast furnace would not be strong enough to support itself if it was larger and would easily collapse unless some steel pillars were used in the middle to stabilize it.

But Ren Zhong is now in Yangcun, so where can he find any extra steel to be used as pillars for the blast furnace? He can only wait until the iron is smelted.

The main channel for the Eighth Route Army to obtain steel now is to tear up the railroad tracks, which makes it impossible for Ren Zhong to raise any demands.

Lifting railroad tracks is not only risky, but also extremely difficult. With the current transportation means of the guerrillas and main force in the base area, it is difficult to travel long distances with one railroad track. At this time, a normal railroad track is 8 meters long and weighs more than 40 kilograms per meter, which means one rail weighs more than 300 kilograms!
A horse cannot carry this weight. If it is to be carried manually, it will take at least 6 to 8 strong men to carry it together.

In addition, the cutting tools were primitive, and it was difficult for the Eighth Route Army to cut the steel into small pieces. This made it very difficult for the Eighth Route Army base to obtain steel, and there was a severe shortage of steel in the arsenal.

Even the mines were made from clay pots, so how could Ren Zhong ask for some steel to build this earthen blast furnace?

Originally, Ren Zhong felt a little guilty about engaging in iron and steel smelting. After all, he was a complete layman in this area and he was also a liberal arts student. Now he was forced to learn chemistry and mechanical processing.

Now he is forced to engage in construction and smelting. This is like he is being forced to become an all-round science student.

Fortunately, the old book "Primitive Iron Making" written in a special period introduced the detailed construction and smelting process of the earthen blast furnace in great detail, and all of it was written in traditional Chinese characters. Ren Zhong simply tore off the cover of the old book and took it with him for reference.

This time, with the guidance and optimization of Associate Professor Hu Rentao, Ren Zhong printed out the new design drawings and felt more confident.

In the world of Bright Sword, three days after the brigade commander left.

Yangcun.

"Brother Ren, have you got all the design information for iron smelting?" Li Yunlong asked Ren Zhong eagerly, because Ren Zhong had said before that he would send a message to the organization to find the information on traditional blast furnace iron smelting and send it over.

Although Li Yunlong didn't know how Ren Zhong sent the information, those mysterious copper plate materials and manual punch machine parts all appeared in the cave near Yangcun in this way.

So Lao Li believed it firmly.

He is a simple-minded person. As long as he can get something, he is happy. He never thinks too much about how the thing came about.

After spending almost two months together, Lao Li thought he had gotten to know Ren Zhong very well.

This person should not have any bad intentions towards the base. Otherwise, all the things Ren Zhong is doing for the base now will cause heavy losses to the Japanese and puppet troops.

No spy would do this, and the self-torture tactic is not about shedding one's own blood.

"Old Li, it should be here. I'll go get it later." Ren Zhong pretended that he didn't know, said goodbye to Old Li, and really went to the cave he often went to.

In the cave, he naturally put away the things he brought with him, packed them into a package, and returned to the village leisurely.

In order to maintain the sense of mystery, Ren Zhong made up an excuse that the people in his organization did not like to deal with outsiders, so this cave near Yangcun had a wide view and could see far around. Li Yunlong ordered that no one could approach this cave without orders.

Inside the cave, machine tools, materials and some strange things may appear at any time. I don't know how Ren Zhong's organization transported these things in here without being noticed.

Anyway, Li Yunlong is a pragmatist. No matter what Ren Zhong says, as long as it is good for him, Li Yunlong will believe it. He is a completely qualified tool.

After returning with the peerless secret book, Li Yunlong couldn't wait to take a look at it for a while, but found that there was basically nothing he could understand.

"Brother Ren, this is still the old rule. You give the orders and I'll do it." Li Yunlong handed the secret book back to Ren Zhong without any shame.

Ren Zhong smiled, opened the secret book, and started arranging a new round of work for Li Yunlong.

Building an iron-making blast furnace is by no means an easy task, especially after Hu Rentao's optimization and revision, the traditional blast furnace is much larger than the original version and requires several times more materials.

But for Li Yunlong, these are not a problem!

"Everyone from the second and third battalions, get to the construction site and work in three shifts 24 hours a day! The first battalion is in charge of the defense zone. If they don't have enough people, I'll go find more. Make sure to build this blast furnace in the shortest possible time." Li Yunlong said fiercely.

"Stop, stop, Lao Li, you are trying to kill yourself. The construction site doesn't need so many people. One battalion and three companies can be divided into three shifts. Just work for 18 hours." Ren Zhong was shocked. Lao Li was good in everything except that he was like a madman when working on the project.

"Another battalion has to go to the mines to mine iron ore and coal. We are doing this on two fronts. After selecting the blast furnace site, we will mine the iron ore and coal simultaneously. Then we have to crush them into particles. We also need to build a large warehouse."

Ren Zhong was not as anxious as Li Yunlong. This thing could not be accomplished by just saying a few words; it would take time.

"But once the blast furnace is built, it will be difficult to keep it secret. If it is an open-air blast furnace more than ten meters high, even a nearsighted Japanese reconnaissance pilot will not be able to escape.

We have to hide the blast furnace by relying on a stone wall like an earthen kiln. To be honest, the cliffs near the water near the New 1st Regiment’s station were really good.”

Now the base is heavily surrounded by the Japanese and is at an absolute disadvantage in terms of strength. Once the Japanese find out that the base has started to produce steel on a large scale, it will be disastrous. I'm afraid Yoshio Shinozuka will lose sleep and will come in large numbers.

"Brother Ren is right. Tell us your requirements and I'll ask someone to look for them. We have no way to deal with the Japanese reconnaissance planes and fighter planes right now. If we are really found by these beasts, we will be doomed." Li Yunlong also had a headache.
