Zhu Biao walked inside and saw official slaves coming and going, carrying coal and brass, or forging iron and blowing bellows under the guidance of the blacksmith.
Zhu Biao saw a few familiar faces among the official slaves. They seemed to have been from the official dental bureau, but it was difficult to ask.
Zhu Bai caught a glimpse of the surprise on Zhu Biao's face but did not explain.
Among these official slaves, there are indeed people from the Guan Ya Bureau, the same group of Ya chiefs who were captured by Hu Guangcheng before the Chief Secretary, such as Chang Quan.
Originally, Zhu Bai wanted to send them back to Tianwei Station, but after much thought, he realized that these people knew too much.
If they talk nonsense to others, a lot of things will happen.
Anyway, we have to work hard here, and it's safe if it's enclosed by a wall, so we brought them all here.
Now they are not afraid no matter how much they know, because no one here can get out.
Only those who can come in are safe enough.
Chang Quan and the others couldn't get what they wanted. Although the work here was hard, the food and accommodation were very good. Compared to doing corvee work in the Wei, it was much better here.
No matter how good your health is there, you can't last more than a year.
Zhu Biao picked up a Yanling knife and looked at it carefully.
Only then did he realize that the surface of the knife, which looked as bright as a mirror, had tiny patterns like daisies.
Zhu Bai briefly explained the process of Yan Ling Dao to Zhu Biao.
In short, low carbon steel with low hardness but good toughness is used on both sides, and high carbon steel with high hardness is used in the middle.
This Yan Ling Dao looks simple, but it is actually very learned.
It was not easy for him to tell Zhu Biao in such detail.
After all, it's his trade secret.
The piece of high-carbon steel in the middle is not simple. It is Utz steel. It uses the forging method of "Damascus steel". Wrought iron and carbon steel are mixed, folded and forged together, so it forms layers with clear boundaries.
The fine dark patterns. This special pattern is called Mohammed pattern.
The fine, dandelion-like pattern above is basically caused by two materials with different properties mixed together.
The bright areas are steel with high hardness, and the dark areas are steel with strong toughness.
It not only looks good, but also because the pattern can make the blade microscopically form serrations invisible to the naked eye, which is sharper than a flat blade.
There is a more poisonous way, which is to feed poison to the blade. The blade will be as dark as the night sky, and the patterns on it will be as beautiful as stars.
Ancient craftsmen knew how to extract trace elements and add them to steel, and could judge based on experience which region's iron ore could produce good steel and forge good weapons.
They traveled all over the world's mountains and rivers in search of high-quality iron ore, smelted it in furnaces in mines, and tried it piece by piece. It often took several years or even more than ten years to produce a magic weapon.
He was different. He knew how to add elements such as silicon, manganese, sulfur, phosphorus, chromium, nickel, molybdenum and copper. He also added a certain amount of manganese ore powder and iron ore to a closed graphite clay crucible and melted it into a
High carbon molten steel, and then sprinkled with several other trace element mineral powders that have been crushed and finely screened for forging.
And his official offices are spread all over the country. As long as he can tell the specific location of various minerals, someone can help him get them.
His knives are not only beautiful and light, but also cut iron like clay and can break hair when blown.
Moreover, there is no communication between the various crafts in the arsenal, and the craftsmen of each craft only work on their own craft.
In this way, only Zhu Bai has mastered the essentials of weapon processing. Whoever wants to conquer the world in the future must rely on him.
Some craftsmen in the shop were dissatisfied and made fake knives that were exactly the same in length, thickness, width and width. You could not tell the difference just by looking at them, but as soon as they touched the Yan Ling knife made by Zhu Bai, it broke immediately.
Therefore, Wei Suo also gave up his thoughts of imitation and waited obediently for his turn.
Zhu Biao was amazed and asked Zhu Bai: "Twelfth brother, how do you know how to make weapons?"
Zhu Bai smiled: "I don't know. I just hired a craftsman to think about it while making it. After I made a handful, I let Hu Dafa try it. Hu Dafa took it in his hand and weighed it and he knew. After the finished product was made, he gave it to the generals.
We tried it out and asked for their opinions. In fact, from the beginning to the final take shape, we made dozens of versions."
Zhu Biao nodded slightly.
He pointed to the groove on the Yanling knife and said: "People in the past thought this was a blood groove, used for puncture and bleeding. In fact, it was not. Because on the battlefield, no one would wait for blood after piercing it.
, but immediately pulled it out and continued fighting."
This was the first time Zhu Biao heard someone talk about this. He was very interested and asked: "What is this slot actually used for?"
Zhu Bai smiled: "I didn't know that before, but later someone told me that this is used to reduce weight. If it is too thin, it will bend easily, and if it is too thick, it will be too heavy, so I make it thicker and then make this groove."
In this big house, wild goose feather knives are made in the backyard and handguns are made in the front yard. Originally there was a wall and a small door in the middle to separate them. Now the door is locked and there are guards guarding it.
On weekdays, people in the front yard and back yard do their own thing, and everyone comes in and out through their own doors.
Seeing Zhu Bai and Zhu Biao coming, the guards hurriedly opened the door.
Compared with the ding-ding-ding-ding-ding-ding-ding-ding-ding-ding-ding-dong-ding-dong-ding-dong-ding-dong-dang-and-fires and the fires blazing into the sky in the backyard, the front yard is very quiet.
Because craftsmen are making very small parts.
When Zhu Bai was making that "bicycle" before, he was very troubled by chains and marbles.
Nowadays, the parts made by these craftsmen are also very precise. Each person is given a cast iron mold, and the parts must be placed into the grooves. If there is a slight deviation, they will not fit in, and they must be polished or started all over again.
These tasks require great vision and patience, so the craftsmen in the front yard are mainly young and middle-aged people who are quiet and steady.
I'm too old, my hands are shaky and I can't see clearly, so I can only be responsible for assembly and guidance.
Just like the front yard, here there are also several craftsmen working in groups, and each group is only responsible for processing or assembling one part.
Zhu Bai picked up an assembled gun and asked Zhu Biao: "Brother, do you want to give it a try?"
Zhu Biao's heart jumped twice.
Zhu Bai had previously used this "artifact" to capture Deng Zhen who wanted to coerce him.
In Maoshan Station, Zhu Biao saw the power of this thing.
He had wanted to try it for a long time, but Zhu Bai always said: "The safety of this is not guaranteed yet. I will wait until I improve it."
Unexpectedly, it took so long for him to actually touch the gun.
Zhu Biao took the gun.
It was very heavy, heavier than he thought.
Zhu Bai pointed to the front sight on the hand gun and the target on the tree: "In order to prevent the hand from shaking, I used my best left hand to support my right hand for the first time. I feel that my eyes, front sight, and target are three points and one line, and I can shoot.
.”
Zhu Biao took aim for a long time and fired a shot. The recoil made the tiger's mouth numb.
Zhu Bai said: "The tiger's mouth hurts a bit. This has been improved. It was still very hot before."
Zhu Biao walked over and looked at the target, and he hit it on the edge, a little off.
The marble passed through the target and sank into the tree trunk.
