After building the shed and smelting furnace, Xu Chen directed the poor men to learn how to dig and process tin ore, which ones can be used, and those that cannot be used. Pick out the useful ones in a vine basket and carry them under the wooden shed. If they are too big, people will be arranged to smash them with stones.

Some poor people knew that doing so would exchange for the tribe with the urgently needed pottery, salt crystals and other good things, so they didn't need to urge the great witches and the clan leader to work honestly. So after half a day, hundreds of people returned and flew back and forth to get thousands of pounds of tin ore.

On the third day, Xu Chen officially began to smel the first furnace of tin.

In order to have poor people, he did every step very carefully and seriously, striving to make the men who were arranged by their great witches to learn to understand and understand.

These simple techniques have no problem with some men who can burn kilns in the Ba people or the Alliance tribe. They can do better if they can be seen at first sight, and even Xu Chen doesn't need to say more.

For example, burning firewood into the earth stove was the simplest action, but these savages had never used this kind of artificially built stove, so they didn't know how to set up firewood to make the fire burn more vigorously, rather than having too much firewood plugged in, which collapsed inside and blocked the fire holes and flue.

As for the ratio of placing ore and broken wood into the smelting furnace, Xu Chen himself did not make any decision. These savages from the primitive tribe looked at the stars and looked confused.

Faced with such a group of apprentices with zero starting point, Xu Chen could only show and explain over and over again. After slowly filling the smelting furnace, seal the furnace and start ignite it. Then, he kept explaining over and over again how to keep the fire from extinguishing, making the fire burn more vigorously, how to use a wooden stick to stab the furnace to maintain airflow input and other basic kiln firing techniques.

For a whole day, Xu Chen was working on the fire burning procedure that everyone in later generations was proficient in.

Finally, the fire was lit smoothly, and the thick smoke of the smelting furnace slowly turned into blue smoke, the sun set completely, and the day passed again.

The four major bitternesses in life: burning kilns, shaving irons, raising boats, and grinding tofu.

These work has been going on for years, not only monotonous and boring, but also extremely tiring physical work, especially when burning kilns and making iron, which is full of smoke and fire, and the heat and poison are dying quickly.

Among them, the kiln is the most bitter. When the kiln fire is together, you must stay next to the kiln regardless of day or night. If the kiln fire is unstable, there will be no slackness. Once the kiln fire is unstable, the goods will basically be scrapped.

Therefore, this night, Xu Chen did not dare to close his eyes, but stayed by the smelting furnace, constantly adding wood and fire, waiting for the temperature of the smelting furnace to rise, and kept guarding until nearly half of the night, watching the tin ore filled with the inner furnace begin to collapse downwards, and then turn into half of the furnace red like burning coal. Then, he took a few hunters and poor students to stir it with wooden sticks, picked out the slag on the surface, and then continued to add ore and wood chips into it.

This continued to go on until it was lightly dawn. Looking at the half-pot of red metal liquid in the smelting furnace, Xu Chen could no longer hold on. He pried open the stones of the furnace sealing furnace by himself, and then a stream of red tin water flowed out along the grooves.

Because there was no long pottery spoon for casting in advance, nor was there a carefully prepared casting mold, the tin water flowed directly into several small square pits that were casually pulled out of mud and sand.

After all the tin water in the smelting furnace flowed out, Xu Chen asked someone to pick out all the remaining slag inside and anneale the furnace.

Then he was too lazy to check the smelted tin, so he turned it back into the wooden shed, wrapped in thick animal skin and fell asleep.

By the time he was awakened by the loud noise of talking loudly, it was already bright.

The weather is gloomy, the cold air in the river valley is rushing, the air turns into ice, and the ground is covered with frost.

In the past, it was so cold that the primitive people would not get up so early to go out. However, just dawn today, a group of poor people who were involved in staying up late to smelter ran back and reported to the great witch that they had smelted a kind of shining Pokémon.

So the great witch brought a large group of people to watch what mysterious items were Xu Chen's stones that had been burning for several days and nights.

The tin water flowing in the mud and sand has long solidified into silver-white metal, and a large piece of emitting a metallic luster.

A large witch of the poor tribe and a large group of men, women, young and old gathered around the large pool of metal, and discussed loudly in surprise.

No one would have thought that Xu Chen had such magical ability to burn some useless stones into juice, and after solidification, it would have such magical shapes and colors.

This kind of thing burned from the stone naturally has a metallic beauty, and it can reflect the face of a person without saying that the silver light can be seen. So a large group of people squat or stand around the open space in front of the smelting furnace, exclaiming and making noises, but no one dared to touch it.

Not daring to touch does not mean being uncurious.

Therefore, when Xu Chen walked over with his eyes yawning, he saw a group of savages in fur, just like a group of curious wild cats, stretching his claws to constantly test the tin blocks on the ground. Occasionally, he stretched over and didn't dare to touch them, so he quickly retracted his hand.

Seeing Xu Chen coming, a large group of people suddenly jumped away like a blow-out. While making way, almost everyone looked at him in awe.

The great witch gestured to Xu Chen with excitement on his face. The two Lapu hunters and the Cha hunters next to him quickly gestured to perform a three-party translation. Xu Chen roughly understood that the witch was praising him for his greatness, and at the same time asked him what the use of burning something like this was.

Xu Chen naturally won’t say it. He just said that this thing can be used to make some items. In the future, the Ba tribe and Gonghuo tribe will burn as much as the Ba tribe and Gonghuo tribe will need.

The witch was very happy and said that she could touch this thing.

Xu Chen naturally satisfied her small wish, and asked someone to find a wooden stick, dig out the whole piece of tin from the sand, and then bent it with his hands and broke off a small piece and handed it to the big witch.

Seeing Xu Chen breaking the tin with his hands, the savages around him exclaimed again.

Xu Chen tried to pick up a whole piece of tin and weighed it, but found it was very difficult, probably 60 or 70 kilograms.

In this way, he could probably infer the output.

As long as these poor people become skilled in the future, as long as they ensure the supply of ore and wood, a smelting furnace can smel at least hundreds of kilograms of metal tin a day, and more than one ton in a month. Production may be stopped in the rainy season of spring and summer, but in the autumn and winter, seven or eight tons can be made in half a year.

Of course, this is just a theoretical output. If the smelting furnace and mining speed are increased, the output will also double, but it will also consume more manpower and material resources. In the case of insufficient food supply, it is difficult for poor people to continue.

However, stimulated by pottery and salt, Xu Chen believed that some poor people would work hard to smel.

Therefore, after Xu Chen judged the output, he needed to give a suitable exchange ratio, which not only allowed the poor to feel at a disadvantage, but also allowed them to have sufficient enthusiasm to work.

So after some careful consideration, Xu Chen found a stone axe and slowly cut the large piece of tin in front of everyone into six pieces of similar size, each weighing about ten kilograms.

Then Xu Chen began to explain the exchange ratio with the Dawu. In this way, six pieces of tin can be exchanged for two pottery bowls or a large pottery plate. The two pieces can be exchanged for a small pottery pot or pottery pot. Four pieces can be exchanged for a medium pottery pot or pottery pot. Six pieces can be exchanged for a large pottery such as a pottery pot or pottery pot. If you exchange salt, three pieces can be exchanged for a small bag of salt, which looks about one pound.

Dawu was not dissatisfied with Xu Chen's exchange ratio.

Because she didn't know how complicated and hard it was, she only knew that after she got up, her tribe members had learned to refine stones into such magical metals, which looked very relaxed, and could change a lot of pottery by working a day and a night, which was still very cost-effective in her opinion.

Because the tin mine is near the tribe, the wood is not valuable, it is full of hillsides, so I can just pick it up. As long as Xu Chen always needs this metal, almost everyone in the poor has pottery in the year, and some of them are replaced with salt crystals and fishing nets and other items, so that the poor people will soon become rich.

Although she doesn't understand mathematics, she knows that increasing wealth depends on accumulation.

The skins need to be accumulated, and the food also depends on accumulation. Even the population has been reproduced and accumulated over time, which has led to such a huge tribe now.

Xu Chen was able to help them turn this useless stone into a kind of exchangeable wealth, which actually filled her with surprise and gratitude.

In addition, it is not convenient to come and go here. Xu Chen suggested that if there are poor people who can help transport these tins to the Cha tribe outside the mountain or the Gonghu tribe downstream, the exchange rate can be increased by one to two times.

Faced with this proposal, the witches of the poor clan and a group of patriarchs expressed their willingness to accept it after a brief discussion, but they hoped that Xu Chen could teach the skills of erecting rattan baskets so that they could transport them.

Xu Chen naturally satisfied them very happily.

After the transaction conditions and trading methods were agreed, Xu Chen arranged a group of hunters to teach the poor people to learn how to weave baskets, and at the same time he taught them to make straw sandals and rub ropes.

Ordinary ropes are bark ropes, which are not strong and durable. They can make fishing nets, but they are very easy to damage. Now, almost all the Ba tribes and Gonghuo clan tribes have been replaced with hemp rope fishing nets, and daily bark ropes are only used for temporary life scenarios such as simple binding.

Xu Chen didn't want these neighbor tribes to get free technology, but it is still very necessary to teach some low-level and superficial technologies for the sake of common progress of mankind and future transactions.

Xu Chen will not teach the techniques of picking and sewing hemp for the time being. After all, spinning and weaving are still the core skills of the Ba people, and weaving needs to gain more benefits for the Ba people through weaving.

When the bronze knives are made, the Ba people will add another core wealth growth weapon, and then they can promote spinning and weaving to more alliance tribes.

However, simple trading tribes like the poor will not enjoy this kind of shared technological progress treatment.

They want more advanced items, but can only be exchanged.

Or it was to submit to the new alliance tribe of the Ba people.

Xu Chen has no time to take care of this tribe with difficulties in transportation. As long as he can live in peace and continue to provide tin, he can only provide tin. After all, some poor people are really poor and eat soil. Even if they surrender, they still need to spend a lot of effort to help and guide the construction.

Once a poor tribe delivers goods to the Cha tribe or Gonghuo tribe and contacts the outside world, it is estimated that it will be much easier to recover it in the future.

I just paid a few more pottery and some salt before and after.
