Chapter 222 Slave Shackles (Please vote and subscribe)

After confirming the plan for two days later, Luo Chong and You Fu ended their conversation and started to do their own things. You Fu took the You clan to visit the various jobs of the Han tribe in detail, and then found their favorite professions to join, while Luo Chong began to prepare for the allocation of the 200 slaves.

In order to make the slaves obedient and not resist, they need to wear shackles that restrict their activities. At present, the Han tribe can only use bronze to cast shackles. There are difficulties, but the problem is not big, and we can find a way to solve it.

The structure of the shackles is divided into 9 parts, a pair of leg shackles, each shackle is divided into two semicircular parts, which is a concave shape when viewed from the side. A 90-degree copper sheet will extend from both sides. The copper sheet has holes and is connected by hot rivet technology.

Added together, there are four semicircular copper sheets, two copper nails, and a copper chain in the middle that is divided into three sections, that is, three straight copper rings. It is of course better to make it denser, but the workload will be much greater. Using three sections of chain is the simplest way to ensure that people can walk with shackles.

After designing the process flow and the size of the workpiece, Luo Chong immediately handed over these data and methods to the metallurgical team of Dazui.

Although there are nine parts, there are actually only two models, one is a copper sheet, and the other is a copper rod with a diameter as thick as the arrow shaft, which is directly cast and then processed later.

The later processing is also very simple. The three chains are nothing more than burning the cast copper bars red, then bending them into a flat copper ring, and bonding the joints with copper water. Unless it is removed by violent means, it is impossible to remove it in this life.

The four-piece shackles are first cast with four copper plates with holes reserved at both ends, then burned red, and smashed into a semicircular shape.

For this purpose, Luo Chong first asked Da Zui to cast two bronze molds, a copper anvil in the shape of a "concave" and a hammer in the shape of a "convex". When using it, put the red-hot copper sheet on the concave copper anvil, and then hit it with the convex copper hammer, and the copper sheet will bend into a semicircle.

As for the copper nails, it is easier to deal with. Just chop off a small section from the copper bar. When installing, put the red-hot copper nails in the reserved holes of the shackles, put the copper anvil underneath, and then use a hammer to flatten it.

There are many hammers in the Han tribe, because the axe that was cast at the beginning was a style with an axe blade on one side and a square head on the other side, with a handle in the middle. It is both an axe and a hammer, and it can be regarded as a multi-functional tool, ahem, at least there are two uses, this is also to solve the problem of insufficient copper production.

In two days, the tribesmen once again witnessed the leader's wild imagination. He could come up with a tool, or torture device, to restrain slaves. They also had a higher understanding of the leader's ability to invent and create. The leader was really omnipotent.

Dazui led the metallurgical team to work overtime and take turns. In two days, they finally made 100 pairs of shackles. At this time, there was no bronze reserve, so they had to start smelting copper again.

On the morning of the third day, Luo Chong asked Dashu to bring 100 slaves and began to shackle them.

The slaves were still tied up like a cross and had not been released. In addition, they had not eaten decent food for nearly a week. They all looked half-dead and were obviously thinner than when they were first captured. At this time, they were pulled over by the soldiers and pressed on the ground to install shackles. They did not resist at all. They really had no strength.

Several people pressed the slave firmly to the ground. Next to them was the furnace of the metallurgical group. Big Mouth first took the concave copper anvil and placed a processed half-copper plate of shackles on it. Then he put one foot of the slave on it and then fastened the other half.

Then he took out a red-hot copper nail from the furnace and placed it in the butt hole of the copper plate. Then he used an axe to knock the two sides of the copper nail flat, and then poured some cold water on it. With a hiss, the cold water was evaporated by the hot copper nail, and the temperature of the copper nail also dropped.

According to the principle of thermal expansion and contraction of metals, the volume of the rivet will shrink, and then the joint will be firmly locked. This is the hot riveting process. Before welding was invented, this method was basically used for metal connection.

However, the sturdiness of the hot riveting process is no worse than that of welding, but the operation efficiency is not as fast as welding. However, this hot riveting process has made a great contribution to mankind. In the past, many steel frame bridges were connected one by one with rivets.

The rivets on the outside of the two feet were nailed first, and then the hole on the inside was directly pierced with a bent copper strip, and then the joints of the copper strips were poured with copper water. After cooling, the shackles were installed.

The first slave with shackles was pulled up, and then a soldier untied the wooden stick tied behind him and released his arms.

The slave was a little dazed. He thought that the tribe was going to kill them, but he didn't expect that they would suddenly untie his arms. He didn't know what this meant. He just took a step forward, and then he heard a clanking sound under his feet. It was the sound of the chain hitting.

The slave was a little dazed and took a few more steps, but the chain limited the size of his steps. He took a big step and stumbled and fell to the ground, causing the surrounding warriors to laugh.

The slave sat up on the ground and touched the golden thing on his ankle. It was so heavy and solid that he couldn't tear the shackles apart no matter how hard he tried.

His arms were freed, but he was shackled again. Wearing this thing didn't mean he couldn't move, but it only gave him a very small range of movement. They still couldn't run away. So these people didn't kill them, but put this thing on them. What on earth did they want to do with them?

The slaves were a little desperate, and even wanted to die. If they were allowed to live but not given freedom, God knows what they would be forced to do. Anyway, it must be very painful, the kind that would be worse than death. Now death seemed to have become a luxury for them.

One by one, the slaves were put on that strange shackle, and then their arms were released. But this time they were all obedient. They did not run away, but just sat together or lay on the ground. They were too hungry, had no strength, and did not want to move.

The Han tribe was changing the shackles for the slaves. At the same time, on the east bank of the stream, after two days of marching, Shu Da had already arrived at the Li tribe with a team of 200 people.

The people of the Li tribe had not had time to go out to collect food and hunt wild animals this morning, and they were surrounded by the team led by Shu Da in their living area.
