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

A series of musical notes sounded around the Tongshan Colorful Pond. This was not the sound of a thawed stream flowing freely, but the sound of Han Dashenzi, who was letting himself go, holding a hard stone and smashing it around.

Han Cheng had a look of wanting to cause trouble at this time. He arranged for the others to get the malachite, while he walked around here and there, and when he saw a stone that he didn't like, he would go up and touch it.

After a while, a surprise finally appeared.

After a dark stone was hit, the black outer shell faded away, revealing a bright yellow color under the sunlight.

Looking at this fist-sized object that shines bright yellow in the sun, Han Cheng smiles with joy.

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

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

However, the pure copper outside will oxidize after a long time, just like iron. The black shell-like existence that Han Cheng smashed open is the oxide.

This piece of pure copper attracted the attention of many people. People from the Qingque tribe came over and touched it with their hands, feeling its heavy weight and its texture that was different from stone. They seemed very happy and curious.

Thinking of what Han Cheng had said before, some people felt a little regretful. How could copper, which looks much more beautiful than iron, not be as hard and useful as iron?

From this we can see that judging people by their appearance has been going on since ancient times.

With this piece of pure copper as an incentive, Han Cheng hammered more vigorously.

However, he did not let others interfere in this matter. Shang, Mao and others were still dealing with malachite and some other copper ores.

After all, these copper ores are the main raw materials for copper smelting, and pure copper that exists directly is a very rare thing.

He was not simply hammering around looking for pure copper. In the process he was also observing the distribution of the copper mines here, and getting a simple preliminary understanding of the situation here.

"here!"

Shang over there seemed to be some excitement and shouted.

The people scattered around heard the shouting and gathered over. Han Cheng also went over there carrying another small piece of pure copper he had obtained, wanting to see what Shang had discovered as soon as possible.

Seeing Han Cheng coming over, the people surrounding him consciously made way for him, and the scene here appeared in front of Han Cheng.

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

It can be seen that this pit was just dug.

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

There is no doubt that this is a high-quality malachite mine.

After asking Shang about the situation and checking for a while, Han Cheng immediately gave an order not to let everyone search around, but to start digging here with tools.

The stone hoes and bone shovels of the Qingque tribe are not very useful here and are easily damaged.

So after clearing the not-too-much soil around the small stone pit, the mining tool became the most common and extremely versatile weapon in primitive times - the wooden stick.

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

For some reason, the ore in this area is relatively broken, with gaps in the middle. If there are places that cannot be dug up by hand, you can poke a sturdy wooden stick into the gap and use the principle of leverage to move it back and forth, or you can smash the stick down along the gap to pry it open.

Open-pit mining is done in such a casual way.

Of course, at this time, it would be impossible for Han Cheng not to accompany him like this.

Because before bronze was invented, he couldn't make any good tools.

Once we find the breakthrough point of a high-quality mineral vein, our work efficiency will be high. When it was about to get dark, a lot of high-quality malachite had already been piled up not far from the mine pit which had become much larger and deeper.

Stones are extremely heavy, not to mention ores containing metals, which are even heavier than ordinary stones. Just this pile of stone could easily weigh more than a thousand kilograms.

Han Chengdu was a little surprised that the copper ore mining was going so smoothly. If they continued at this pace, they would be able to return home in less than two days.

Seeing that it was getting late, Han Cheng asked his men to stop what they were doing and go towards the cave of the Tengshe tribe that no longer existed.

They will stay here for the next few days.

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

The caves of the Tengshe tribe have not been inhabited for more than half a year, so who knows what might have taken up residence in them.

This "thing" certainly does not refer to fox spirits or ghosts, but those poisonous insects that like to drill into cracks.

So Han Cheng asked people to find a lot of dead branches and leaves, put them in the hole and light them, and keep smoking.

A lot of wet mugwort found nearby was piled on top of the dead branches and leaves.

Many people did not care much about the Son of God's cautious behavior. After all, they grew up in the wilderness since childhood.

We have only lived in houses in recent years. We used to live in caves, but there wasn’t much danger there.

Of course, although they thought so, they still did things according to the Son of God's requirements. Some people went into the cave to crush the leaves, and some went to cook.

Flames rose in the cave and choking smoke filled the air.

The people who didn't care much before gradually changed their color, because as the fire in the cave burned, things that made them give off goose bumps gradually happened.

More and more things came out from it.

There were spiders the size of small eggs with hideous spots on their backs, long legs and stiff hairs, large centipedes as long as chopsticks, black bodies with red claws, scorpions with their tails sticking up high, and long, green insects that were hard to name but looked bad at first glance...

The people of the Green Bird Tribe turned green in the face at the sight of so many guys who had to run out in a hurry due to the flames and thick smoke.

Although they were ferocious, they were still a little scared when facing these poisonous insects.

Compared with ferocious beasts, these tiny poisonous insects are sometimes more frightening, making people feel helpless and unable to guard against them.

After seeing so many things, they all looked with admiration at the Son of God who was standing aside with a wise look on his face.

Fortunately, the Son of God is here this time. Otherwise, if someone were to spend the night in this cave under such circumstances, perhaps someone would never wake up again...

Little did people know that the Son of God, who appeared calm on the surface, was actually very panicked at this moment.

Han Cheng just thought that since no one had lived here for a long time, there might be more poisonous insects, but he didn't expect that there would be such a terrifying number.

Another reason was that he suddenly remembered the cave in his tribe that was used as a kitchen and canteen...

(A bit stuck...)
