I am a primitive

Speaking of it, it is very reasonable that bronze appeared first in the history of civilization development, and then iron and steel appeared, because the melting point of the metal ores needed for bronze is much lower than that of iron and steel.

After Han Cheng announced the news, Wu and the others beamed with joy.

The existence of such things as iron knives and axes made them deeply aware of the usefulness of metal tools. How can they be unhappy when they hear Shenzi announce that they can make tools from another kind of metal from this beautiful green stone? ?

As for Han Cheng's words that it is not as good as iron, they simply ignored it. For them, as long as it is metal, it is fine.

"Where did you get this stone?"

Han Cheng asked the long legs standing not far away.

The long legs still seemed a little dazed, no matter what, he never thought that metal could be extracted from the stone that he used as a talisman.

He had seen metal before. The somewhat blackened ax carried by the lame carpenter in the tribe was made of metal.

Even though he had seen the lame guy chopping down trees with a black ax several times, Long Legs was still amazed at the speed.

Now that he knows that the amulet he has been wearing for a long time can extract a kind of metal, how can he not be in a daze?

"In the... Horde..."

Long Legs slowly told the origin of malachite in broken Mandarin.

Han Cheng also slowly figured it out.

On a mountain near the Teng Snake Tribe, the vegetation is sparse, and there are some beautiful blue puddles there. Long Legs picked up a piece of beautiful malachite of suitable size there, polished it, tied it with a rope and hung it in the Neck as a talisman.

During the long-legged talk, Han Cheng also heard another thing.

That is, someone in the Tengshe tribe once drank the beautiful water, and then had a stomachache, and then died.

Since then, they have gained a knowledge that the beautiful water in those pits is not drinkable.

This is the characteristic of the primitive era. A lot of knowledge is acquired with the death of people.

Han Cheng asked the long-legged man why he drank the water in the stone pit, and the answer he got was that the water there was as blue as the sky, and some people believed that after drinking it, they would be blessed by the gods.

Han Cheng couldn't help sniffling, it really is the ignorant who is fearless.

By the time the rain stopped for nearly a day, it was already dark.

The rain stopped, but because it was already night and the sun did not rise, the air was still cool, and it was the most comfortable to sleep at night.

Han Cheng didn't feel much sleepy at this time. On the one hand, he slept too much during the day, and on the other hand, he was thinking about the surprise news he got today.

There is no place to find when you break through the iron shoes, and it takes no effort to get it.It is a true portrayal of the news of the copper mine this time.

It was a pleasant surprise and a surprise to look around for copper ore to no avail, and to find it right under our noses.

The scale of the copper mines there has grown from Han Cheng, who doesn't care too much, because according to the current situation of the Qingque tribe, even the smallest copper mine is enough to use

I have to go to the old lair of the Tengshe Tribe to see what is going on with the copper mine, and wander around to see if I can find traces of the tin mine.

After thinking about copper mines and things related to copper for a while, Han Cheng made such a decision in his heart.

After all, he is the only latecomer in the tribe who is more familiar with these things, so he has to go to this matter.

And he had to leave as soon as possible. On the one hand, he wanted to confirm these things as soon as possible, and on the other hand, Bai Xuemei would give birth soon.

He had to do something about it before Bai Xuemei gave birth, and then return to the tribe from there.

No matter what kind of custom is in this era, when Bai Xuemei gives birth, Han Cheng will return to the tribe and stay by Bai Xuemei's side.

Because this is the most vulnerable moment for a woman, and she is prone to danger. Although Bai Xuemei's agility is unbelievable until now, she doesn't have the slightest awareness of being pregnant.

Another important reason is that he wants to welcome the birth of his child.

This is the first child of his own flesh and blood, future generations and now, and he doesn't want to miss this important moment.

-------------Chapter Dividing Line---------------

Early the next morning, Han Chengcheng called the high-level officials of the tribe together, and in the meeting room of the green brick and large tile house, he told the decision he made after thinking about it last night.

As soon as these words were uttered, they immediately received unanimous approval from everyone.

A few people are yearning for the scene of having a lot of metal utensils in the tribe.

The second is that the current tribe has just been relatively idle for a long time.

There is still a long time before the harvest of millet and soybeans. At this time, as long as there are more people weeding and loosening the soil, it is not too busy.

For following Han Cheng to the Teng Snake Tribe, several people showed enough enthusiasm, and they all wanted to follow Han Cheng to see the magical metal mine, even Wu was no exception.

Of course Wu couldn't go. He was getting old, and the most taboo thing was traveling long distances for a long time.

After some discussion, Han Cheng made a decision.

Shang and Hemao, two people who often take people out for trade, led a trade team to go with him.

As for the transactions with the other small tribes around, let's put it aside for now.

After all, the biggest purpose of the trade team is to find metal mines.

In addition to the 20 people in the trade team, they also brought Junior Brother Sha, the sharpshooter of the Qingque tribe, as well as long legs and a few stronger slaves.

Originally, Han Cheng wanted to take Senior Brother with him, but after thinking about it, he finally brought Junior Brother Sha with him.

The main reason for doing this is that Wu is relatively old.

If he and the eldest brother left the tribe at the same time, Wu would have to work hard again.

Everyone in the tribe is delighted and looking forward to this trip.

However, such people did not include Bai Xuemei, who had a big belly and looked a lot fatter.

Since being rescued by Han Cheng, she has never been separated from Han Cheng. Now that she knows that Brother Cheng is going to leave the tribe to a far away place and will not take her with him, of course she is not happy.

Of course, Bai Xuemei couldn't follow, the Teng Snake tribe's lair was not close to the tribe, and it would take a long time to go back and forth, so what's the matter with a pregnant woman following her?

In this era, the medical and health conditions are not good, and the death rate of newborn babies is scary. Han Cheng does not want Bai Xuemei to give birth halfway.

This is not a very good thing for adults or children.

After all, you can still get rest and use some rough medical methods in the tribe, but giving birth on the way is really blind.

"Who will raise the silkworms after you leave?"

Han Cheng pointed to the two dustpan silkworms and said to Bai Xuemei, and once again sacrificed the great method of silkworm breeding.
