I am a primitive

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 finishing 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 typed this sentence was once again excellently confirmed, the rocks that were not honest and stayed well, but had nothing to do but 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 spread on it, 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!"

-------------Chapter Dividing Line---------------

"melted!"

"This is tin ore!"

After the charcoal fire continued to burn for a while, the smashed tin ore at the bottom layer began to melt.

Han Cheng, who saw this scene through the hole on the side of the stove, shouted excitedly.

The rest of the people who had been waiting for the news also cheered.

Han Cheng looked here for a while, and saw that the flames began to spread to the charcoal above through the melting tin ore at the bottom, and the gradually melting tin ore had a tendency to flow out, so he quickly filled the lowest opening with charcoal. There is also clay to firmly block.

"Hoohoo~hoohoo~"

The person who presses the wind and Gulu has already changed to the third one.

Han Cheng looked down obliquely from the top of the furnace, and saw that most of the ore inside had melted, so he asked someone to poke open the higher hole, and melted slag began to flow out of the hole, which was even more serious. The heavy molten metal remained under the furnace.

"Put the clay pots on and turn on the stove!"

When the ore in the furnace had melted and the slag was almost flowing, Han Cheng gave an order, and immediately two people came over with long wooden sticks.

Put the thinner end of the stick against the hole under the stove, and with a sudden force, the blocked hole was opened.

The wooden stick was quickly withdrawn, and the molten metal flowed out along the hole on the stove and fell into the clay pot.
