Tongshan looks unique after the rain.

Many snowflake-sized copper rusts became clearer and covered the rocks, looking extremely magnificent.

Nearly thirty people from the Qingque tribe were distributed in and around Tongshan. They held wooden sticks or octagonal hammers made of thick copper in their hands, and would occasionally separate the grass or hammer on some stones.

The people of the Green Bird Tribe have been here for six days. Because they brought hammers made of crude copper this time, they can mine copper ore much faster, at least faster than the first and later mining.

It turns out that "original soup turns into original food". Sometimes it is very necessary to cook beans and burn bean pods.

After several months of smelting, most of the copper ore brought back before has been used up. Although the technique is a bit rough, a lot of crude copper has been obtained.

Han Cheng's main purpose in coming to Tongshan this time was to look for tin ore, but obtaining copper ore was also essential.

So after arriving here, Han Cheng first concentrated his efforts on mining enough copper ore for this transportation, and then he had people search for tin ore in the vicinity with all their might.

Long Legs held a stick in his hand and kept fiddling with the grass, lifting up the dead branches and leaves covering the ground to see if there were any unusual stones here.

After searching for a while, I looked up at the people around me doing the same thing, and my already good mood became even better.

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

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

This made Long Legs feel so close to the citizens of the tribe.

He had this feeling not just because of these.

Many things that happened on the way here were conveying this message to him.

For example, according to the rules of the tribe, he could only eat twice a day, but this time it was different.

When the food was distributed at noon, the respected Son of God would allow people to give him some. Although it was not much and the quality was not as good as that of others, he was still extremely touched.

At night, although he still slept at the farthest place from the fire, it was not as far away as before, so he could sleep close to other people in the tribe...

Changtui once again took out the lucky charm hidden under his clothes, held it in his hand, with a heart full of piety.

This lucky charm was made after the Qingque tribe discovered a large amount of malachite and he found a more beautiful piece of malachite.

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

After a while, he carefully put the lucky charm inside his clothes, close to his skin, and then continued searching here with the stick.

“Huahua…”

The stick passed through the not-so-dense grass, which was pushed aside, and some tiny specks of dazzling light appeared in front of the long legs.

This sudden change frightened him so much that he immediately took a few steps back with his stick in his hand, looking at that place with a look of alertness and fear.

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

The grass was parted, and the dots of dazzling light that were seen just now did not appear.

Long Legs blinked in confusion, not understanding what was going on.

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

“Here! Here!”

He shouted loudly.

Long Legs didn't know what this thing was, let alone whether it was the kind of stone the Son of God needed to find.

But this glowing thing looks very unusual.

The people around were startled by his shouting and gathered around.

Han Cheng, who was still wandering on the hillside of Tongshan Mountain, also heard the sound. He was delighted and quickly came down the mountain and headed towards the place where the long legs were.

When Han Cheng arrived, quite a few people had already gathered there. They were pointing and talking about the grass that had been pushed aside by sticks, and seemed very curious.

Han Cheng also saw the tiny dots of light shining through the sunlight, and a look of joy immediately appeared on his face.

He took two quick steps closer and found that the glowing object was a small piece of rock.

The rocks are a little yellowish, and there are some silver spots of varying sizes distributed in the yellow rocks.

The rock was only the size of a bowl, and the surrounding area was covered with soil and weeds.

Is this a silver mine?

This was the first thought that came to Han Cheng’s mind.

He squatted there and watched for a while, then reached out and grabbed the weeds beside the rock and pulled them aside. The dense roots lifted up a piece of soil, revealing more rocks covered in mud underneath.

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

However, silver and tin are quite similar in color. Han Cheng, who is not very familiar with either of the rocks, really can't tell whether they are silver or tin.

Han Cheng looked at these rocks containing some metal substances and fell into deep thought, while other people in the tribe looked at the Son of God nervously.

More than half a year has passed since I learned about the metal ore from the Son of God.

During this period, the people of the tribe, under the leadership of the Son of God, also achieved some achievements in this regard, but there was always something missing, and they failed to produce a metal as useful as iron.

Now I come to look for it again, I hope I can get a good result.

Under everyone's expectant gaze, Han Cheng pointed to the exposed rock and said, "Knock some of it off and let's see if it is tin ore."

After saying that, he stood aside. Immediately, an impatient guy came over with a hammer made of crude copper and smashed it with a loud bang.

The saying that the exposed rafters will be hit first by the rain was once again perfectly proven. The rocks that did not stay still and insisted on emitting some light were soon smashed beyond recognition.

The perpetrator carried the knocked-down rocks into a leather-lined basket and walked to the other side of the Copper Mountain with full expectation.

Here, there stands a not-too-tall vertical furnace, which was built after Han Cheng arrived.

The purpose is not to smelt copper ore here, but to identify what is suspected to be tin ore.

Among metals, tin's melting point is not very high, and it is much lower than that of silver.

Han Cheng, who was not very good at distinguishing different types of ores, could only use this method to distinguish between silver and tin ores.

Yesterday's rain made the furnace a little wet inside and out, so such a furnace was obviously not suitable for melting metal.

Han Cheng asked someone to light a fire to heat the stove.

He took a hammer and smashed the ores into smaller pieces. He picked out the ones with more obvious metallic colors and put aside the waste that looked like rubble.

If this job is done only by hand, the efficiency is quite slow and it is not very standard.

If it can be confirmed that these are tin ores, then we will have to think of some other ways to speed up the mineral processing in future production.

After drying in the furnace, these not-so-large amounts of ores have basically been roughly separated.

Han Cheng added another layer of carbon into the stove while the carbon in it was still burning.

A layer of stone suspected to be tin ore is placed on the charcoal, then another layer of carbon is placed on the stone, and then another layer of tin ore is placed on top.

Just like this, layer of tin ore and carbon are laid on top, making it like a sandwich.

Han Cheng stopped only after laying three layers of crushed tin ore.

The wind began to whir, continuously sending oxygen into this simple stove, accelerating the burning of the charcoal and raising the temperature inside.

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

After all, this is the closest we have been to finding tin ore since our search for ore.

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

“It melted!”
