Wild farming: I was hugged by the cold patriarch

Chapter 290 290. Building a Market

The Huaxia tribe is now busy building a road from the tribe to the copper mine.

Ye Sang arranged the captured prisoners to build roads, reclaim wasteland on both sides, and build thatched houses for temporary residence. After the wasteland was reclaimed, it was immediately cultivated.

The chief of the Bear Head tribe chose to surrender and listened to Ye Sang's arrangements. Ye Sang did not leave them behind and brought them all over to build roads, open up wasteland, and plant crops. No one was left behind.

With so many people working together, the road was built extremely smoothly and reached the vicinity of the copper mine in just three or four days.

Next we can develop the copper mine.

The refining of copper is similar to that of iron. The first step is to crush the selected ore into small particles. It would be better if it can be ground into fine sand.

The second step: put the ground fine sand ore into water and use flotation to separate the copper-containing ore.

Step 3: Place the copper-containing ore into a copper smelting furnace and heat it to a high temperature to oxidize the copper in the ore to produce copper oxide.

Step 4: Calcine copper oxide and carbon together at high temperature to generate metallic copper.

Step 5: Heat the copper again at high temperature for refining.

Step 6: Pour the refined copper solution into the mold and make it into the required shape.

Ye Sang saw these steps clearly in the mall, memorized them, and then wrote them down on paper in front of everyone, telling everyone the method in the form of an oracle.

The barbarians believed in the oracle and had complete confidence in her. After getting the method, they started casting it immediately.

Although we have the method, the practice still requires exploration and familiarity. Ye Sang is refining copper with everyone here, and together they have figured out the best method, and then casting goes smoothly.

Half a month later, the first copper coin was born.

This copper coin is just round with a square in the middle, and there is no way to engrave a pattern on it. Ye Sang tried to engrave it with a knife, but the marks were too shallow and not beautiful, so he gave up this method and thought that he should add the pattern in the mold. After thinking for a while, Ye Sang wrote four words in the mold: Huaxia Tribe.

Refine copper coins again.

After refining the copper coins, Ye Sang discovered that the four words were reversed. Only then did she realize that the words should be engraved reversely like a seal, so that the words on the refined copper coins would be correct.

This really made it difficult for Ye Sang. Firstly, she didn't know how to carve a seal, and secondly, she couldn't do it and was very anxious.

Later she thought of a solution.

Write the words on paper and then look at the words from the back of the paper. This is how they should look when engraved on the mold.

Thinking of this method, Ye Sang finally finished the pattern on the mold. Not only did he write four words, he also processed the edges of the copper coin. The copper coins he refined were almost the same as he remembered.

Seeing the newly refined copper plate, Ye Sang smiled and said, "We can build a market now!"

Ye Sang asked the tribesmen to continue refining copper plates while she began to prepare for building a market.

It is not difficult to build a market. First, you need to choose a site, then fence off the land, and then attract people. It is similar to the previous markets. The possible change is that this market has rules, and transactions can be made with copper coins instead of bartering.

Ye Sang chose a flat and wide location for the market, with a road next to it. It was close to all the tribes and convenient for going to the market.

After choosing the location, Ye Sang formed a team to be responsible for building the market.

The market is divided into several areas, and each area will trade on its own without affecting each other.

After Ye Sang completed the planning, the construction of the market began.
