The copper mountain that is sunny after the rain looks unique.

The patina, the size of many snowflakes, becomes clearer and covers the rocks, making it look magnificent.

Nearly 30 members of the Qingque tribe were distributed in and around the copper mountain, carrying wooden sticks or eight-sided hammers made of coarse copper, and from time to time they separated the grass or put two hammers on some stones.

It has been six days since the people of the Qingque tribe came here, and because they brought a hammer made of blister copper this time, they have been able to mine copper ore much faster, at least faster than the first later mining.

Sure enough, it is still 'the original soup into the original food', and boiling beans and burning beans are sometimes very needed.

After several months of smelting, the copper ore brought back before has been used for seven, seven, eight, eight, and eight, although the technique is a little rougher, but also a lot of blister copper.

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 when he arrived here and concentrated his efforts on mining enough copper ore for this transportation, Han Cheng asked people to go all out to find tin ore in this vicinity.

Long Legs carried a stick in his hand, and kept playing with the grass here, lifting the dead branches and leaves that covered the ground, and examining whether there were any unusual stones here.

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

He was the only one who 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.

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

He felt that way, and it wasn't just because of that.

Many things that happened along the way this time were conveying this news to him.

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

When the food was eaten at noon, the respected Divine Son would also let people give him some, although it was not much, and the condition was not as good as the others, but he was still very moved.

When he slept at night, he still slept in the farthest part of the fire, but not as far away as before, and could sleep close to the rest of the tribe......

Long Legs once again took out the lucky charm covered under his clothes and held it in his hand, full of piety.

This lucky charm was made by finding a large number of malachite in the Qingque tribe, and he found a more beautiful piece of malachite again.

Longleg is now more devout to Lucky Charms, as he feels that the reason why he is luckier than the rest of the slaves is because of Lucky Charms.

After a while, he carefully put the lucky charm into his clothes and stuck it to the meat, and then continued to search here with a stick.

"Whoa......

The stick passed through, the not-so-dense grass was pushed away, and some sparkling lights 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, and looked there with a look of alarm and fear.

After a while, when nothing unusual changed, he tentatively walked a few steps forward and stretched out his stick to pluck the grass.

The grass was pushed away, but the sparkling, somewhat dazzling light that I had just seen did not appear.

Long Legs blinked a little confusedly, not understanding what was going on.

He stood there for a moment, then took two more steps forward, and the sparkling white light reappeared.

"Here! Over here! ”

He shouted loudly.

Longleg didn't know what it was, and he didn't know if it was the kind of stone that Miko needed to find.

But this glowing thing looks very unusual.

The people around him were startled by his shouts and gathered around.

Han Cheng, who was still wandering around the halfway of the copper mountain, also heard this voice, and he was overjoyed, so he quickly came down from the mountain and walked towards the place where the long legs were.

When Han Cheng came to the front, there were already a lot of people gathered here, pointing at the grass that had been pushed away by the sticks, and talking about it from time to time, looking very curious.

Han Cheng also saw the sparkling light that appeared under the sunlight, and the joy on his face suddenly revealed.

He walked two quick steps to the front and noticed that what was glowing was a small patch of rock.

The rocks are somewhat yellowish, and there are silver spots of various sizes scattered in the yellowed rocks.

The rocks are the size of a bowl, and the surrounding area is covered in dirt and weeds.

Is this a silver mine?

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

He crouched there for a moment, then reached out and grabbed the weeds on the edge of the rocks and pulled them up to the side, the dense roots bringing up a patch of soil, revealing more of the mud-stained rocks below.

But don't be a silver mine, at this time, silver is really not as good as tin for the Qingque tribe.

However, silver and tin are really similar in color, and Han Cheng, who is not very familiar with the rocks that appeared at this time, really couldn't tell whether it was silver or tin.

Han Cheng looked at the rocks containing some metallic substances, and the rest of the tribe looked nervously at the Divine Son.

It has been more than half a year since I learned about the metal ore from Miko.

During this time, the people of the tribe under the leadership of the Son of God have also made some achievements in this area, but they have always lacked something, and they have not made a metal that works as well as iron.

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

In the expectant eyes of everyone, Han Cheng pointed to the exposed rock and said, "Knock it down a little, let's see if it is tin ore." ”

As he spoke, he stood aside, and immediately a guy who couldn't wait came over with a hammer made of blister copper, and smashed it with a 'clang'.

The outcropping rafters Yu hit the sentence first and was once again very well confirmed, if you don't stay honestly, you have nothing to do but emit some brilliance out of the rocks, and soon they will be smashed beyond recognition.

The assailant carried the knocked down rocks in a leather-lined basket and walked to the other side of the copper mountain with great anticipation.

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

Not to smelt copper ore here, but to identify what appears to be tin ore.

In metals, the melting point of tin is not very high, and it is much lower than that of silver.

Han Cheng, who is not very clear about all kinds of ores, can only use this method to distinguish silver ore from tin ore.

Yesterday's rain made the stove a little wet inside and out, and such a stove is obviously not very suitable for melting metal.

Han Chengcheng made people raise a fire to bake the stove.

He carried a hammer to smash the ores into smaller pieces, and at the same time picked out the more obvious metallic colors, and cleared aside the scraps that looked like rubble.

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

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

After the furnace is dried, these ores, which are not too much, are basically separated in a general way.

Han Cheng took advantage of the fact that the carbon in the furnace was not extinguished, and added another layer of carbon to it.

The charcoal is topped with a layer of stones suspected to be tin ore, and the stones are topped with another layer of carbon, and then the tin ore is continued to be laid.

In this way, a layer of tin ore and a layer of carbon are spread, and it looks like a sandwich biscuit.

After laying three layers of smashed tin ore in a row, Han Cheng stopped.

The wind began to whirl, sending oxygen into the improvised stove, accelerating the burning of the charcoal and raising the temperature inside.

Han Cheng and the rest of the tribe looked a little nervously waiting here, expecting the result.

After all, this is the closest I've ever come to finding tin ore since the search for ore.

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

"Melted!"
