A group of people stopped at the entrance of Chagu.

Here, the impact beach where the two rivers meet, you can already see various colorful stones.

In addition to some common fluorite and quartz stone and calcium stone, dark red or blue-purple are tart copper ore, light gray are charcoalite, steel-gray tan copper ore, indigo blue-copper ore, and there may be marachite mixed with cyan green, and even purple-red pure copper particles.

Xu Chen drooled while watching.

A group of people followed Xu Chen and quickly picked up a lot of stones of various colors on the river beach.

“Rido gag!”

The dragon pointed at Chagu and reminded that there were more inside.

Xu Chen nodded slightly.

At this time, he could basically make a judgment.

These ores were washed out from this valley by water.

However, the stream in this valley is not large, and it has been completely dry and broken.

During autumn and winter, the Wu people would go deep into this place when hunting and gathering, but it was almost the farthest distance they would live on weekdays.

In fact, the main collection scope of the Wu people is the river beach near the hillside where they live, while the scope of men hunting is mainly the river beach near the valley entrance.

Very few come from the mountains.

Some of these copper ores are beautiful for decoration, and some can be used as pigments.

Therefore, when hunting and gathering, they will pick up some of them and take them back when they encounter good-looking and useful ones, but that's all.

If you are used to paint oil paint on the rocks of a cave or on the body, a stone can last for a long time, and there is no need to collect a large amount of it.

At most, some natural copper blocks and malachite will be more interested, but there is never any need to collect them actively.

After the water is eroded in summer, I will pick up some when I see it when I come to hunt and collect in autumn and winter.

It looks good, but its value is almost zero.

Even every time the tribe gathers, there is almost no change in things, so after picking them up, they are usually thrown in the cave to eat ashes.

If it weren't for Xu Chen's willingness to exchange these things with pottery and linen cloth, the Wu people would never have spent half a day running to pick up these stones.

They came to pick up some of them last autumn and winter, but Lao Lao was so eager to carry them to the Ba people, but he just changed some small pottery such as pottery spoons and spoons.

It is valuable, but it doesn't seem to be big, better than nothing, so for the Wu tribe, it is a bit more costly to make these stones.

One is heavy, the other is less.

I looked at the river beach everywhere, but even after picking it up, there was not much. Most of them were buried under the mud and sand of the river beach. There were no handy tools, so it was even more troublesome to dig.

It’s better to go hunting if you have this little time. It’s easier and more convenient to get a few animal skins with greater value, and it can also solve the problem of food, killing two birds with one stone.

This is not only the idea of ​​the Wu people, but also the current reality.

Until basic food and clothing are solved, mining will not be proactive or motivated.

"Go in and take a look!"

The Chagu is not too big, and has been almost completely covered by thorns and weeds.

However, when the stream is washed away, you can still see a large number of scattered gravels of large and small sizes. These stones have traces of mineral veins, and are intertwined with layers of colorful blue, blue, gray, etc., which are copper ore that has been washed and collapsed from the mountain for countless years.

After erosion, these large stones slowly shatter. The copper ore inside will be washed onto the main river outside, and then taken downstream, slowly shattering into colorful gravel. There may be some hard malachite and original copper ore particles, which will be carried and buried into the mud and sand.

This fora valley is not long, it only looks two or three miles away.

But after walking less than halfway inside, it was impossible to move forward. The road ahead was completely blocked by a large amount of collapsed gravel, and thorny vines and trees were growing everywhere, which was basically impossible to pass.

However, there are more copper ores in the valley.

You can see it everywhere.

As we walked in, with Xu Chen's prompt, a group of people found a lot of copper ore that looked good in purity, as well as a lot of malachite and original copper ore grains.

Now he can conclude that this small valley is a copper mine-rich area.

Although the reserves cannot be judged, they are fully mining value.

It’s just that how to mine and how to smel and deal with it needs to be thought of.

The most convenient thing is naturally to find a place near this valley to build a furnace and smel it into copper blocks to transport it out.

However, this requires many people to open mines here and form a professional base. At the moment, if you still can’t eat enough, this method is undoubtedly the most expensive. It involves living, safety, food, tools, etc. Everything must be arranged properly, otherwise there will be a lot of trouble.

The most important thing is that a large number of people are separated from food production, mining and smelting, which will inevitably affect the food supply. Even the Ba people cannot afford it at present.

Therefore, this method that was originally the most convenient was quickly rejected by Xu Chen.

The second method is to build a smelter at the foot of the Wu people's mountain, which greatly increases safety, and the mining and transportation distances are within the tolerance range. It mainly uses the free time in winter and spring to collect food without delay, and it will not consume too much manpower.

However, this is the territory of the Wu tribe. In this way, we need to have closer connections with the Wu tribe, or we need to control the Wu tribe more firmly. Moreover, this is too expensive, and it mainly depends on the Wu tribe. At that time, the Wu tribe's people will make trouble.

The third method is the simplest, that is, to continue to adopt the current barter method, mobilize the Wu people to dig copper ore and get the Ba people to exchange pottery and linen. They only serve as ore exporters and do not participate in any other work.

However, from mining to transportation to Ba people, the most labor and time are consumed, the most cost is the most, but the least efficiency is.

After observing inside and outside the Chagu for an hour and collecting a lot of copper ore, Xu Chen asked someone to carry it in a basket and go back and think about it slowly.

Copper smelting is not the most urgent thing to be needed right now.

At present, he only needs to be sure there is indeed a copper mine here.

Before finding lead or tin ore, copper alone is not particularly meaningful. No matter what equipment is used for, the significance of decoration is far greater than practical value.

As we walked, half a day passed.

Back on the river beach at the party, the transaction was basically over at this time.

Several tribes that came to attend the Witch Lord Conference were already packing their luggage and preparing to leave the Wu tribe.

Muba, several tribe leaders and a group of tribe leaders of the Ukrainian tribe were talking on the river beach. When they saw people coming back, they all rushed up to ask about the situation.

Xu Chen said that he had found what he needed.

Mother Ba is very happy.

Although copper is of no use in Xu Chen's opinion, the simple copper tools such as copper knives and copper needles he made are very useful, but they cannot be dropped and must be polished frequently. However, compared with primitive tools such as simple and crude stone knives and shells, it is a completely epoch-making artifact.

Unfortunately, copper smelting is troublesome and the output is extremely low.

Xu Chen used pottery and linen to exchange several large baskets from several tribes, and finally only made a little bit of this magical metal called copper.

Although the cost is huge, Muba and all tribe members still think that the more copper the better.

Because Xu Chen said that if you use copper to make pots, pans, pots, it will be stronger and better than pottery, and you don’t have to worry about breaking.

Although pottery is easy to use, it breaks quickly. A group of women are careful every day, but pottery is still broken every now and then, especially pottery jars for cooking porridge and vegetables. Sometimes they suddenly break themselves up. Several times, they even scattered the freshly cooked food everywhere, feeling both distressed the food and the pottery.

Therefore, when it comes to using pottery to exchange copper ore for smelting copper, Mo Ba and a group of women fully support Xu Chen.

Because they were almost fed up with the fragility of pottery.

For primitive people who have been working hard since childhood, life has never been so cautious, and holding pottery is more terrifying than holding a child.

Xu Chen didn't feel that he had to replace all pottery with bronze ware. First, there was no need, and second, he was not as luxurious as he was now.

The reason why he said this was just to let Mo Ba support him in continuing to smel copper.

It seems that the effect is still good now.

Given that the opportunity for mining is not yet fully ripe, Xu Chen has already had a general idea on his way out of the valley.

That is to continue to implement the current plan of replacing ore with pottery.

This not only gives the Wu tribe the motivation to mine, but also the Ba tribe does not need to pay more manpower, material resources and energy.

It would not be too late to start large-scale mining and smelting after he had collected all six tribes.

So the three-day meeting of the witch masters was officially announced to end.

The Ba people and several tribes that came said goodbye to each other and set off one after another.

The leader of the Wu tribe led a group of tribe leaders and all the people to send the Ba tribe to the river beach outside the valley entrance.

The twin sisters hugged each other and cried and comforted each other, and finally had to say goodbye with tears in their eyes.

I used to be together every day, but now I can only live in two places.

Although the ending was far beyond what the two expected at the time and was definitely a happy situation, it was not easy to meet after breaking up.

Although the two tribes have only half a day to reunite, they have now become witches of their respective tribes. They must take the development of the tribe as their own responsibility, and they are no longer the little girl who is ignorant of the world at the time. They have to bear heavy responsibilities on their young shoulders.

Before saying goodbye, Xu Chen reminded the Wu tribe leader and a group of leaders that the Ba tribe continued to exchange large quantities of copper ore, hoping that they would dig and collect them quickly during the winter and spring seasons, and also choose a group of smart and flexible men and women to send them to the Ba tribe as soon as possible to learn advanced experiences such as spinning, weaving, building and farming.

Although the leader of the Wu tribe had great complaints and dissatisfaction with Xu Chen, these things were indeed related to the long-term development of the Wu tribe, so he still cooperated very well and said that he would select people to send them as soon as possible.

Of course, this learning process is not about Ba people having food and drinking, but about bringing their own food and offering some other items.

Xu Chen is willing to provide these technologies, but at the same time he also said that the Ba people have limited food and financial resources, and cannot support these people, nor can they teach these technologies in vain, and they need to exchange items.

Of course, not only the Wu tribe, but other tribes are treated the same way.

There are not many things required for tuition, only a few animal skins or baskets of food or gold amber gemstones.

Xu Chen would not be abusive to these savages, nor would he let them get free sex into a habit. Instead, he needed to use this method to create a sense of urgency and pressure for all tribes to work hard to collect and discover more valuable things.

In addition, the Ba people are preparing to expand the second phase of the compound. These people will also provide additional labor while studying.
