I am a Primitive Man

Copper Mountain, which is sunny after the rain, looks unique.

Many snowflake-sized patinas became clearer, covering the rocks, looking extremely magnificent.

Nearly 30 members of the Qingque tribe are distributed in and around Tongshan Mountain, carrying wooden sticks or octagonal hammers made of thick copper in their hands, separating the grass from time to time, or hitting on some stones Two hammers.

The people from the Qingque tribe have been here for six days. Because they brought a hammer made of thick copper this time, they can mine copper ore much faster, at least faster than the first post-mining.

Sure enough, it is still original soup and original food, sometimes it is very necessary to cook beans to burn Osmunda.

After several months of smelting, the copper ore brought back has been used for seven or eight times. Although the method is rough, a lot of crude copper has been obtained.

This time he came to Tongshan, Han Cheng's biggest purpose was to find tin ore, but the acquisition of copper ore was also essential.

So after arriving here, after concentrating on mining enough copper ore for this transportation, Han Cheng made people go all out to find tin ore near here.

Holding a stick in his long-legged hand, he kept fiddled with the grass here, and lifted the dead branches and leaves covering the ground to see if there were any unusual stones here.

After rummaging through the long legs for a while, I looked up at the people around me who were doing the same thing. I was already in a good mood, but it became even better.

Among the people who came this time, only he was a slave, and the rest were citizens of the tribe.

At this time, the citizens of the tribe were doing the same thing as him.

It made Longlegs feel so close to the citizens of the tribe.

It's not just because of these things that he feels this way.

Many things that happened on the way here this time are conveying this news to him.

For example, according to the regulations in the tribe, he can only eat food twice a day, but this time it is different.

When sharing food at noon, the revered Son of God would ask someone to give him some. Although it was not much, and the quality was not as good as other people's, he was still very moved.

when you sleep at night,

Although he still sleeps in the farthest place from the fire, it is not as far away as before, and he can sleep next to other people in the tribe...

The long legs took out the lucky charm covered under the clothes again, and held it in his hand, full of piety.

This lucky charm was made by finding a more beautiful piece of malachite after the Qingque tribe discovered a large amount of malachite.

Long Legs is now more devout about the lucky charm, because he feels that the reason why he is luckier than the rest of the slaves is because of the lucky charm.

After doing this for a while, he carefully put the lucky charm into his clothes, sticking to the meat, and continued to search here with a stick.

Wow...

The stick passed through, and the not so dense grass was pushed away, and some dots and dazzling lights appeared in front of the long legs.

This sudden change frightened him, holding the stick, and immediately took a few steps back, looking there with vigilance and fear.

After a while, seeing no abnormal changes, he tentatively took a few steps forward and stretched out his stick to poke the grass.

The grass was pulled away, but the dots and some dazzling lights that I saw just now did not appear.

Long Legs blinked his eyes in doubt, not understanding what was going on.

He stood there for a while, then took two steps forward again, and the dots of white light appeared again.

Here! Here!

He shouted loudly.

Long Legs didn't know what it was, let alone whether it was the kind of stone that the Son of God was looking for.

But this glowing thing looks very unusual.

The surrounding people were startled by his shout, and they gathered around one after another.

Han Cheng, who was still wandering around on the hillside of Tongshan, also heard the voice, and he was overjoyed, and quickly came down from the mountain, heading for the place where the long legs were.

When Han Cheng came to the front, quite a few people had already gathered here, pointing at the grass that had been pushed away by the stick, and discussing a few words from time to time, looking very curious.

Han Cheng also saw the dots of light exposed under the sunlight, and joy appeared on his face immediately.

He took two quick steps and came closer, only to find that the glowing thing was a small piece of rock.

The rocks are somewhat yellowed, and there are some silver spots of different sizes distributed in the yellowed rocks.

The rock is only the size of a bowl, and the surrounding area is soil and weeds growing.

This is a silver mine?

This is the first thought that appeared in Han Cheng's mind.

He squatted there and watched for a while, then reached out and grabbed the weeds on the edge of the rock and pulled them aside vigorously. The dense roots lifted up a piece of soil, exposing more rocks below that were stained with soil.

But it must not be a silver mine. At this time, silver is not as real as tin to the Qingque tribe.

However, silver and tin are quite similar in color. Han Cheng, who is not very familiar with the rocks that appear at this moment, really can't tell whether it is silver or tin.

Han Cheng looked at these rocks with some metal substances and fell into thought, while other people in the tribe looked at Shenzi nervously.

It has been more than half a year since Shenzi learned about the metal ore.

During this period of time, under the leadership of the Son of God, the people of the tribe have also made some achievements in this regard, but there is always something missing, and they have not produced metals that are as useful as iron.

Now come to search again, and it would be good to get a good result.

In the expectant eyes of everyone, Han Cheng pointed to the exposed rock and said, Knock it off a little, and let us see if it is tin ore.

After he finished speaking, he stood aside, and immediately a guy who couldn't wait came over with a hammer made of thick copper, and smashed it with a 'bang bang' sound.

The outcropping of rafters Yu first hit this sentence was once again excellently confirmed, the rocks that were not honestly staying there, and wanted to emit some brilliance, were soon smashed beyond recognition.

The assailant carried the knocked rocks in a leather-lined basket, and walked to the other side of the copper mountain with full of expectations.

Here, there is a shaft furnace that is not too tall, which was built after Han Cheng came here.

Not to smelt copper ore here, but to identify things that are suspected of tin ore.

Among metals, the melting point of tin is not very high, and it is much lower compared with silver.

Han Cheng, who is not very clear about the classification of various ores, can only use this method to distinguish silver ore and tin ore.

Yesterday's rain made the inside and outside of the furnace a little wet. Such a furnace is obviously not very suitable for melting metal.

Han Cheng asked people to light up a fire to bake the stove.

And he took a hammer to smash the ore into finer pieces, and at the same time picked out the more obvious metal color, and cleared the waste that looked like miscellaneous rocks to the side.

This matter is only done by hand, the efficiency is really slow, and it is not very standard.

If it can be confirmed that these are tin mines, then we need to think of ways to speed up the speed of beneficiation in future production.

After the furnace was dried, these ores, which were not too much, were basically roughly separated.

Taking advantage of the carbon in the stove, Han Cheng added another layer of carbon into it.

A layer of stones suspected to be tin ore is spread on top of the charcoal, and a layer of carbon is spread on top of the stones, and then tin ore is continued to be spread.

In this way, a layer of tin ore and a layer of carbon are laid on top of each other, making it like a sandwich biscuit.

Han Cheng just stopped after laying three layers of smashed tin ore.

Feng Gulu started whirring, sending oxygen continuously into this simple stove, accelerating the burning of charcoal and increasing the temperature inside.

Han Cheng and other people in the tribe seemed nervously waiting here, looking forward to the result.

After all, this is the closest to finding tin ore since searching for ore.

Once you have tin and master the proportions, you can get good quality bronze.

melted!
