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 official teeth bureau, the same group of teeth chiefs captured by Hu Guangcheng before the Chief Secretary, such as Chang Quan.
Originally, Zhu Bai wanted to send them to Hui Tianwei Station, but after thinking about it, 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 is safe to be 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 going to the guard to do corvee work, this place is already much better.
No matter how good your health is there, you will not be able to survive a year.
Zhu Biao picked up a Yanling knife and took a closer look.
Only then did he realize that the surface of the blade, 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. of fine dark lines. This special pattern has a name called Mohammed pattern.
The fine, dandelion-like pattern on it is basically caused by the mixture of two materials with different properties.
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, and smelted it in furnaces in the mines, testing it piece by piece. It often takes several years or even more than ten years to develop a magic weapon.
He is different. He knows how to add elements such as silicon, manganese, sulfur, phosphorus, chromium, nickel, molybdenum and copper. He also adds a certain amount of manganese ore powder and iron ore to a closed graphite clay crucible and melts it into a High-carbon molten steel is then sprinkled with several other trace element mineral powders that have been rolled 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 knife is not only beautiful and light, but also cuts 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 mastered the essentials of weapon processing. Whoever wants to win the world in the future must rely on him.
There are also craftsmen in the shop who are dissatisfied and make imitation knives that are exactly the same in length, thickness, width and width. You can't tell the difference just by looking at them, but as soon as they touch the Yan Ling knife made by Zhu Bai, it will break 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 about making weapons?"
Zhu Bai smiled: "I don't know. I just asked the craftsmen to think about it while making it. After I made one, I let Hu Dafa try it. Hu Dafa would know after he weighed it in his hand. After the finished product was made, he would show it to the generals. We tried it out and asked for their opinions. In fact, from the beginning to the final shape, we made dozens of versions."
Zhu Biao nodded slightly.
He pointed to the groove on the Yan Ling knife and said: "People in the past thought this was a blood groove, used for piercing and bleeding. In fact, it is not. Because on the actual battlefield, no one will wait for bleeding 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: "Then 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, if it is too thick, it will be too heavy, so I will 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. There was originally a wall and a small door in the middle. Now lock the door, there are guards guarding it.
On weekdays, people in the front yard and back yard do their own business, and each enters and exits through their own door.
Seeing Zhu Bai and Zhu Biao coming, the guards hurriedly opened the door.
Compared with the dinging, banging, and blazing fire 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 need to be placed into the grooves when they are ready. If there's a slight deviation, it won't fit in, and you'll have to polish it again or start over.
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 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 trunk of the tree.
