It is a bit troublesome to cast copper coins, but Xu Chen has been slowly accumulating copper ware since the beginning.

Every time I use the burnt copper juice to cast the utensils, I will never use it out, and some of them will be left. He casts these copper juice into copper coins.

The first few times I used simple clay patterns, but it was a little uncomfortable when I was not big enough, so I chose a piece of sand that I was most satisfied with and made several ceramic patterns. Four copper coins could be cast in each ceramic pattern.

These copper coins are exactly the same size, each weighing about half a tael, and there is also the word "Yiwen" on it.

More than 200 such copper coins were accumulated one after another, and Fang Yun was now in his room.

According to the value set by Xu Chen, a copper coin can be purchased for one pound of copper.

At present, the Wu tribe can smel out about 500 kilograms of copper every month during the peak season. From mining to transportation, processing, cutting wood, and smelting, counting the number of people participating in the Wu tribe is about 40 people. Each person distributes half a kilogram of meat every day, and consumes 1,200 kilograms of grain and 600 kilograms of meat a month.

By this calculation, the purchasing power of a copper coin is about five kilograms of grain or two and a half kilograms of meat.

However, this does not count various factors such as tool loss and time consumption.

In addition, this is currency, not a real equivalent wealth, and its purchasing power is just an imaginary number. Therefore, the purchase value of this money is not stable, and tribes can bargain based on the traded goods.

Xu Chen only needs to exchange it to the Wu tribe at the price of one pound of copper, and then the Wu tribe can exchange it for the food he thinks is enough.

Of course, in order to maintain the purchasing power of copper coins, Xu Chen needs to price the goods sold and traded by the Ba people, such as one cent to purchase a pottery bowl or five kilograms of wheat beans and coarse grains, two cents to exchange for an ordinary animal skin, etc.

As for food such as fish, the prices are not fixed. When the food is not sufficient at present, it will definitely be cheap in summer and autumn, and it will definitely be expensive in winter and spring, and it may not be possible to buy it if you have money. After all, except for the Ba tribe, the grain reserves of most tribes are not enough to meet the consumption of one year.

The larger the type of goods that can be exchanged for copper coins, the more complex the process, and naturally the more expensive the price.

A medium-sized axe weighs five kilograms, including lead and tin, and other metals such as smelting also requires charcoal, installation of wooden handles, grinding and other processes. This axe cannot be measured according to the value of copper. In the past, Xu Chen exchanged ten kilograms of copper for one kilogram of bronze, so the axe was worth fifty cents.

According to normal conversion, it is worth at least 250 kilograms, which is about 70 acres of land per year, which is enough for one person to eat for nearly a year.

It is indeed very expensive to say that it is expensive, but if a copper axe is well maintained, it can be used for decades or even hundreds of years. With the improved production and work efficiency of the copper axe, it is reasonable.

As for the car, it is more complicated and expensive. The wheelbarrow must be at least hundreds of volts, the human-powered carriage has 200 volts, and the carriage has 300 volts up. The Wu tribe can only redeem copper for one month, and it can probably change to a few volts or two volts and carriages.

In addition, Xu Chen will not specifically price large items for the time being, and only needs to specify how much grain you can buy from the Ba people for a penny.

After all, grain is now hard currency. Pottery, bronze, chariots and horses can be used, but they cannot eat for a day.

Therefore, the simplest and most effective way to anchor copper coins to grain at present. Other items can be converted into prices with grain, so that the stability of the value of copper coins can be roughly ensured.

The more copper the Wu tribe smelted, the more copper coins it will naturally be exchanged, and the more things it can buy. After they get used to using money, currency can replace the current barter trading model, and real business can slowly develop.

However, Fang Yun only has more than 200 coins in his hand. To maintain the sufficient liquidity of the three small circles of the Ba tribes, Wu and Hu tribes, it will take at least one to two thousand coins to be enough. Therefore, Xu Chen must quickly cast a batch of copper coins.

In the next few days, Xu Chen was busy leaving early and returning late.

Every day, except for patrolling the expansion of the God Mo Temple and the Eye of the Gods on the top of the hill at the entrance of the valley, as well as the dams and ditches on the other side of the river, I spend most of my time in the smelting workshop to cast money.

It is very simple to cast the mow, pour the melted copper juice into the pottery mold, cool it for a few minutes and open it, and use copper pliers to clip the disconnected burrs into the water basin to cool it down, and then take it out and let the edges polish and smooth it. This way, a copper coin is ready.

There are only three pairs of ceramic molds at present, and only twelve pieces can be cast at a time. Each casting round takes about ten minutes. Because the speed is slow, the crucible only melts about ten kilograms of copper-tin alloy at a time, and only 200 pieces of coins a day. However, casting is not the slowest, but grinding is done. Each copper coin must be carefully rounded with a whetstone, and some of the broken ones must be recasted.

Therefore, although this money can make transactions simple and convenient, for the Ba people, it is also a project that consumes manpower, material resources and time.

Six days later, Xu Chen saw that all the tasks arranged by the Ba tribe in winter were gradually on track, and thousands of copper coins had been cast out, and the people in the Gonghuo Alliance should have returned to the tribes and began to inquire about the paths connecting the tribes. Therefore, he did not waste time and took a team of more than ten people to horses to inspect the road construction plans of various tribes.

The Jade tribe now has nearly fifty horses of all sizes. After having enough horsepower, they no longer have to walk when they go far away. However, it turns out that many tamed horses have been exchanged, and there are more than ten wild horses that cannot be ridden, so the number of people accompanying them cannot be too many.

In addition to Gu Ju’s two personal officials and flag officials, there were also the captain Feng, the commander of the captain and nine hunters with the strongest cavalry and shooting skills.

Mo, the three leaders were arrested for staying and hunting and guarding the Ba tribe, and at the same time supervising the expansion of the Old Mother Temple, the Altar of the Eye of the Gods and the River Embroidery and the ditches project. In addition, they were also responsible for patrolling the Bawu Avenue to ensure the safety of the Hu tribe's logging and charcoal burning and the exchanges between the tribes.

In addition, every month Mo would lead a team to send the Mongolians to get the salt back, and by the way, he would go to the Thunder Clan to exchange various tribes for fur goods such as salt and pottery. The lead smelted by the Five Ghosts and the tin smelted by the Poor Clan has been sent back. This has become a routine official business. He has traveled many times and is very familiar with the water route.

The first stop Xu Chen arrived was the Wu tribe.

Two days ago, the Wu tribe had already received the news that Xu Chen would come today, so Long had already prepared with several fully armed riders. After meeting up, he exchanged a few simple words and then went to Ji tribe while it was still early.

When Xu Chen rescued the Cang tribe, he walked back and forth. Many places were in the valleys and forests, which were rugged and difficult to walk. Fortunately, these primitive tribes traveled between them for safety, and generally did not cross mountains and ridges directly, but walked along the valleys and sparse and spacious places with vegetation. Therefore, the path was very clear, which was in line with the terrain characteristics of road construction.

This road dragon has recently taken a group of hunters back and forth three times. After having horses, they have had a little frequent contact with the Ji tribe, so they are still familiar with the road conditions along the way.

At least, most of the places where these people can walk are not a big problem, and many places pass directly through the river valleys. There is a lack of water in autumn and winter, and the traffic conditions are pretty good.

However, river beaches can be walked in autumn and winter, but spring and summer are definitely not good. When the rainy season comes, most valleys and rivers will be flooded. Therefore, in order to ensure that all seasons can pass, this road must be built in a place where water cannot be flooded. Just like Bawu Avenue, cutting down trees to dig the roadbed and passing through the hillside.

However, if there are areas where water cannot be flooded, you still need to carefully observe the traces left after the previous flowing water is washed away.

Therefore, a group of more than ten people raised their flags and shouted their horses and rode their horses along the vast canyons and forests. When they encountered some narrow or complex places, they needed to get off the horse and carefully observe and discuss. At the same time, they had to mark a newly drawn road map. When encountering some cliffs or huge rocks blocking the road, they also needed to mark them with cinnabar, so that Long and others would recently arrange for people to inquire about a larger area nearby and find a simpler and more suitable road.

In fact, the straight line distance from the Wu tribe to the Ji tribe will not exceed fifteen miles. If you are not afraid of the wolf, bear, tiger, leopard and other beasts in the primitive forest, you will be able to cross two mountains by taking a shortcut.

But you can only walk with your feet, not riding a horse.

What's more, ordinary tribal hunters will not take the risk of climbing these rarely visited mountains.

Therefore, the exchanges between these mountain tribes are all winding and twists and turns along the valleys and rivers, and the road is far away.

After walking and stopping all the way for nearly two hours, a group of people came to the intersection of a valley.

After walking about ten miles ahead, you will reach the Ji tribe. This place is basically considered the hunting range of the Ji tribe.

But when we got here, the group stopped.

Because this is a fork road at the intersection of two valleys, you can reach the Muya tribe to the northwest, go straight to the Ji tribe to the west, and go east to the Hu tribe.

The direction directly to the Ji clan is a slightly low saddle-shaped hill, much shorter than the nearby mountains, forming a pass that is just enough to pass.

Maogongling, this is the name marked by Xu Chen on the map.

The origin of this name is that when I rescued the Cang tribe last time I hunted a tiger here.
