"Ding, ding, ding, ding, ......"

A series of notes resounded around the copper mountain color pool, this is not a thawing stream flowing freely, but the self-free Han Dashenzi is carrying a hard stone and keeps smashing it here.

At this time, Han Cheng had a trouble-looking face, and the rest of the people were arranged by him to make malachite, while he walked around, and when he saw a stone that was not pleasing to the eye, he went up and went up twice.

After a while, there was finally a surprise.

After a swarthy stone was smashed, the black shell on the outside faded, revealing a patch of yellow in the sunlight.

Looking at this fist-sized object, yellow and dazzling in the sun, Han Chengxi smiled.

This is certainly not a piece of gold, but a piece of copper.

Just as there are pure gold nuggets in gold mines, there is also pure copper in copper mines.

However, the pure copper exposed to the outside will oxidize like iron after a long time, and the black shells that Han Cheng smashed open are oxides.

This piece of pure copper has attracted the attention of many people, and the people of the Qingque tribe came to touch it with their hands, feeling the heavy weight of the copper block and the texture different from the stone, which seemed very happy and strange.

Thinking of what Han Cheng had said before, some people felt a little regretful, copper, which looked much more beautiful than iron, couldn't it be harder and easier to use than iron?

It can be seen from this that such a thing as 'judging people by their appearance' has been around since ancient times.

With this piece of pure copper as an incentive, Han Cheng is even more energetic.

However, he didn't let others interfere in this matter, and Yan, Mao and others were still making malachite and some other copper ores.

After all, these copper ores are the main raw materials for copper smelting, and the pure copper that exists directly is only a few things.

He is not simply knocking and searching for pure copper, but also inspecting the distribution of copper mines here in the process, and making a simple preliminary understanding of the situation here.

"Here!"

The mourner over there shouted with some excitement.

The people scattered around heard the shouts and gathered over, and Han Cheng also carried another small piece of pure copper he had harvested to the other side, wanting to see what he had found as soon as possible.

Seeing Han Cheng coming over, the people surrounding him consciously gave way to the road, and the scene here also appeared in front of Han Cheng's eyes.

It is an irregular pit with a maximum depth of only about half a meter, and some green malachite is piled up around the pit.

It can be seen that the pit has just been dug out.

Inside the pit, more green stones were exposed, large and small, irregular, but they looked purer than they had seen before.

There is no doubt that this is the encounter with high-quality malachite mines.

After Han Cheng asked Yan about some information and checked it for a while, he immediately ordered that everyone should not be searched around, but directly use tools to dig here.

The stone skulls and bone shovels of the Qingque tribe are not very useful here, and they are relatively easy to break.

So after clearing the small pit of dirt that wasn't too much, the tools of mining became the most common and versatile weapon in primitive times - wooden sticks.

Of course, there are prerequisites for using wooden sticks to open mines.

I don't know why this piece of ore is relatively broken, there is a gap in the middle, in the place where you can't pick it up by hand, you can poke the strong wooden stick into the gap, use the lever principle to warp back and forth, or smash the stick down along the gap to stretch it open.

Open-pit mining is so casual.

Of course, at this time, it is impossible for Han Cheng to go with him without doing this.

Because he couldn't make any good tools until the bronze was made.

When the sky is about to dusk, the pit that has become larger and deeper is not far away, and a lot of high-quality malachite has been piled up.

The stone is a dead thing, not to mention the ore containing metal, which is heavier than ordinary stones, just this pile, it is easy to exceed a thousand catties.

The copper ore mining went so smoothly that Han Chengdu was a little surprised, and if it continued at this speed, they would be able to return home in less than two days.

Seeing that it was not early, Han Chengcheng asked people to stop their movements and go to the cave of the Teng Snake Tribe, which no longer existed.

In the next few days, they will be in this place.

However, tonight, Han Cheng and the others did not live directly in the cave.

The cave of the Teng Snake Tribe has not been inhabited for more than half a year, and there may be something to live in it.

Of course, this 'thing' refers not to foxes and ghosts, but to poisonous insects and the like that like to drill into crevices.

So Han Chengcheng asked people to find a lot of dead branches and broken leaves and put them in the hole and light them, and they kept smoking.

There were also a lot of wet wormwood found nearby.

Many people don't care much about the careful behavior of the Divine Son, after all, they have grown up in the wilderness since they were children.

It's only been a few years since I lived in a house, and I used to live in caves, so I didn't see any danger.

Of course, I thought so, but I still did things according to the requirements of the Son of God, some of them smashed the leaves and smoked the cave inside, and some of them went to cook.

Flames rose in the cavern, and choking smoke filled the cavern.

People who didn't care much about it before gradually changed color, because with the burning of the cave ** flame, something that gave goosebumps gradually happened.

More and more things are coming out of it.

A few spiders the size of small eggs with hideous spots on their backs, long legs and stiff hairs, large centipedes with long chopsticks and black claws and red paws, scorpions with high tails, and long striped insects that are green all over their bodies and can't be named but are not good things at first glance......

These many guys who hurried out of the flames and smoke saw that the faces of the Qingque tribe turned green.

Although they are fierce, they are really a little frightened when they face these poisonous insects.

Compared to the beasts, sometimes these small poisonous insects are more intimidating, making people feel like they can't start and can't be prevented.

After seeing so many things, they all cast admiring glances at Miko who was standing on the side with a look of Zhizhu in his hand.

Fortunately, there is a god son this time, if not, if you go to this cave to spend the night under such circumstances, maybe someone will never wake up again......

As everyone knows, the god son who is indifferent on the surface is also panicked in his heart at this time.

Han Cheng just felt that there might be more poisonous insects in this place after not living in it for a long time, but he didn't expect that there would be so many terrifying insects.

Another reason was that he suddenly remembered the caves in his tribe that were used as kitchens and canteens......
