After having breakfast the next day, Chen Chao asked Qu to lead the way to see the mountain where the stone was found yesterday, and brought all the tools for rushing to make it.

Li Nong stayed in the cave, and took Chihwa from the original wheelbarrow production department to start making a new wind-powered wheelbarrow.

After going round and round in the mountains, Chen Chao really found an outcrop of a surface ore body. It seems that the open-pit mining of shallow ore bodies is interesting.

Chen Chao took a look, not sure if it was a copper-tin symbiosis mine. Although Xiao Dian's classmate did not carefully mark him on the map, he still scattered a dozen people, led by grass armor, to look around for malachite.

(Note: Some natural copper mines will have malachite and azurite, accompanied by cassiterite. [This is called a copper-tin symbiosis mine, often accompanied by silver and natural copper.])

But it is a pity that a certain system boss did not get a full-point start like Tonglushan, and even a 60-point start with a copper-tin symbiosis mine. )

The one that Qu and Gu Nuxiu loved earlier was indeed malachite, but Chen Chao did not find tin in the digging place, or the digging method was wrong.

After all, there is only the ability to dig in the shallow part of the surface~~

Without digging deeply, everything is hard to say~~

After hastily eating lunch, Chen Chao took the nearly 100 people and started digging.

Although the little old man with the horns was very puzzled, he still took his big follower, the brown witch, to do the logistics work for everyone.

He planned to find another chance to ask Chen Chao when he went back in the evening, why didn't he go back to the tribe soon, and instead led everyone to dig stones here.

Chen Chao raised his hand and hammered his old waist, then turned his head to look at the small pile of rocks on the ground, and shed moving tears.

Isn't it true that a good protagonist can mine by one person?

Why can't Dali produce miracles~~

Why do I have to do it a little bit when I get to my side~~

Isn’t he a protagonist...

(?｀∧′)

The lord of the world is not the protagonist, who else is the protagonist!

In this case, why is the team of nearly a hundred people digging for an afternoon, only this little result...

At this moment, a system boss suddenly missed explosives (sensitive words)...

Thinking of this, Chen Chao felt that his mind seemed to be a decoration.

What kind of explosive (sensitive word) can't come now, but it can still be used to burn water and splash rocks!

This should be possible!

Chen Chao raised his hand and squeezed his eyebrows. This was the end of doing things without thinking, and nearly a hundred people did an afternoon of useless work.

Just looking up at the sky, Chen Chao sighed, it was too late.

When I remembered that I still had a shortcut to copy, it was almost dark.

A certain system boss felt very helpless, so he waved his hand and asked everyone to stop work and return to the cave.

(Note: Fire water splashing method: It uses the principle of rock expansion and contraction. After the fire is fired, water is poured quickly, so that the rock will crack and even become like cutting tofu.

Repairing the piles and digging tunnels are the creative work of human beings to conquer the natural world and let the rocks be subject to human subjective will.

The human mining activity with a long history is also a kind of creative work to conquer rock-ore. Before blasting, miners used the primitive mining method of “fire and water shock” to obtain ore.

There are many interesting explanations about this. Interested students can search by Baidu keywords~~

You can also add book friends-group me to post the website-address, discuss the plot, and chat and chat, the group number is in the comment area~~)

(Note: Regarding the mining method of copper ore: In addition to the fire and water splash method, you can also directly burn the copper ore with fire, and part of the stone can be turned into natural copper.)

After returning to the cave with the poor stone he had just dug, Chen Chao went to see the work progress of the wheelbarrow production team.

Three skilled workers made a wheelbarrow and came out today.

Seeing this, Chen Chao sighed softly, and let Qu return to the team tomorrow.

Add one more person, the progress can at least be faster. It is estimated that the mining speed will be much faster after the water splashing on the fire tomorrow.

Regarding the production of wind-powered unicycles, Chen Chao is still not worried about letting others take over or adding new people to learn.

To add people, at least wait until these people are brought back to the tribe, and then arrange their specific types of work.

After coming back, I took everyone to dinner. When Chen Chao was about to go to bed, he was poked by some old man who had been waiting next to him, and signaled us to go outside and talk.

Chen Chao looked at the little old man with the horns on his face with a solemn look, so he had to support his sleepiness and accompanied him to the cold wind outside the cave.

Rao is the cold winter wind blowing across his face, but it only makes Chen Chao feel that the sleepworm is farther away.

He was dozing off, and he heard a little old man ask, "Why don't we go back quickly, and dig a stone here?"

Chen Chao thought for a while, so now he must convince the little old man to give him examples of all the good things that can be made out of bronze before he can go back to sleep?

So a certain system boss shook his head, sorted out his thoughts, and said, "Are our stone axes sharp?"

The old man with the horns nodded and shook his head again.

To be honest, in his opinion, the stone axe does not seem to be sharp enough, but at present it seems that there is no sharper thing than the stone axe.

Oh... ceramic fragments will be sharp, but ceramic fragments are not good for grasping and using.

So he didn't know how to answer Chen Chao's question.

Chen Chao did not rush to say the answer immediately, but asked again, "Are our clay pots easy to use?"

He will answer this question!

So a little old man with horns nodded frantically~~

Chen Chao asked again, "Are our wind wheelbarrows easy to use?"

A little old man with horns turned into a nodding robot without emotion~~

"Then when we get a wind wheelbarrow, where is the most difficult to get?" Chen Chao asked again.

The little old man with the horns thought for a while, and tentatively replied, "Wood?"

Chen Chao nodded.

It's no wonder that the old man's brain suddenly went online, because Chen Chao was stupid to ask this question.

The entire wind wheelbarrow, isn't it all made of wood?

"Now that we have this kind of stone, we can make a knife that is better and sharper than a stone axe.

With this kind of stone, we can also make a wok that is better than a clay pot.

Not only that, there is this kind of stone. We can also make a saw tool that can handle wood faster, so that wood can be processed faster and better in the future. "

It's not that Chen Chao doesn't want to tell a little old man about the more uses of bronze, but that he can't understand it now.

Because he had never seen it at all, and there was no way to understand what Chen Chao described.

Like the last example of a saw, the little old man was silly.

So Chen Chao gave more examples, such as bronze can make cannons, gun barrels, two-wheeled vehicle parts, etc...

It's useless, because the little old man really doesn't understand...

It is enough to have the most practical ones, which are the most common and frequently used in his life.
