Ancient stone.

Bite.

Granite.

Boom.

I don't know what kind of stone it is.

Bang.

……

In the room, Han Cheng rummaged through the large and small stones that they had brought back.

Pick up a piece and look at it carefully in front of me for a while, and put it aside in my heart.

Limestone.

Boom.

Han Cheng picked up another stone, and after identifying it, he habitually threw it aside, and then realized that he quickly fished it back and put it aside.

This made everyone who was watching on the side feel a little relieved that they had finally found it, otherwise they would have run in vain this time.

They breathed a sigh of relief, but Han Cheng did not let go, he checked all the stones, and there was no trace of metal ore, so he naturally couldn't let go of his breath.

"Son of God, this ......"

Seeing that Han Cheng seemed to be a little lost, Wu hurriedly pointed to the limestone and said to Han Cheng.

It means that Han Cheng doesn't have to be sad, isn't there another piece?

Han Cheng sighed slightly, limestone is indeed a good thing, but that was before or after.

Now that the tribe has a substitute for plant ash, and there is no place where lime is used on a large scale, metal ore is the most important mineral resource for the current tribe.

In such a situation, he naturally couldn't be happy.

After learning from Han Cheng that the only stone left behind was not a stone that could be used to refine metal, but a stone that could burn cement, Wu and the others were also a little unhappy.

Especially after running outside for a long time, the two of them lowered their heads even more sadly.

Han Cheng realized that something was wrong, patted the limestone in his hand and said, "It's not easy to get good things, and it's even more difficult to get good things like metal all at once."

Didn't we have something to gain this time?

Trade, you open the map and tell me where you got it. ”

Most primitive people's minds are simple, and when they heard Han Cheng say this, their hearts suddenly felt a lot better.

Mao hurriedly took out a piece of salt-made, hairless animal skin.

On one side of the hide, a few rough marks were carved out of a sharper stone, and the traces were dyed black with charcoal.

On the sides of these marks there are some circles that are not quite round.

Circles are not quite the same.

Some circles have only one circle, while others are two circles one large and one small together.

This is the map drawn by the trade firm under Han Cheng's teaching.

The black line represents the road, and the circle represents the tribe.

A separate circle indicates that the number of adults is less than thirty, and two circles indicate that the number of adults is between thirty and sixty.

Although the map looks extremely rudimentary, like a few irregular fruits on a few crooked branches, it has a lot of significance.

At the very least, you can have a general understanding of the location of the surrounding tribes, and it will not be as dark as before.

Trade's memory is very good, especially when it comes to remembering directions.

He looked at the limestone in Han Cheng's hand, tilted his head and thought for a while, his eyes began to search the map, and after a while, he stretched out his hand and pointed to a circle on the map.

Meaning that it is here that the limestone is obtained.

The companion was a little dizzy, this time they went out, they went to several tribes, and there were a lot of things exchanged, he couldn't remember which tribe they got them in.

At the same time, I admired the guy who was not very strong in combat here.

After Han Cheng confirmed it again from Mao, he used a sharp stone to carve the word limestone there.

This way, when the time tribe needs a lot of limestone, where to look for it.

The act of taking a caravan out to trade can also be called a great geographical discovery of the Qingque tribe.

Through discovery and documentation, the people of the Blue Sparrow tribe will become more familiar with the situation around the tribe.

Having recorded this, Han Cheng set his eyes on the other pocket, which contained the various seeds they had exchanged.

There wasn't much surprise on the stone, and I wonder if there was any surprise in the seeds.

It's a lottery.

Reaching out and pulling over a leather bag, he untied the rope on it, and before Han Cheng could pour out, some yellow beads rolled out.

Seeing these yellow balls, Han Cheng's eyes were solemn.

A kind of surprise and apprehension also filled my heart in an instant.

He quickly picked up the small yellow balls and put them in his hand, and observed them carefully.

The globule is yellow all over, and in one place behind it, there is a small patch of brown that resembles a small narrow line.

It is not large, about one-third the size of a soybean in later generations.

Han Cheng looked at it for a while, suppressed the growing joy in his heart, and with a slightly trembling hand, he picked up one and put it in his mouth, chewing slowly and hard.

Soon, the characteristic taste of raw soybeans fills the mouth.

Although the taste was not good, Han Cheng was dazzled.

Seeing Han Cheng's reaction, Wu, Senior Brother, Yin, and the others also became happy, and it seemed that they had found something good.

At the moment, Wu, who is the second boss of the Qingque tribe, also followed the steps of the first boss, and also pinched a soybean grain and put it in his mouth, biting it laboriously and slowly with his open teeth.

I want to taste this kind of seed that makes the gods who have always been known for their mouths eat with a smile on their eyebrows.

As a result, the taste is not very good, neither sour nor astringent, but there is an indescribable taste, which makes people a little uncomfortable.

Han Cheng spit out the soybean grains that he had chewed, found water to rinse his mouth, and the smile on his face became even thicker.

Just opened the leather pocket, and directly gave himself such a big surprise, which really didn't make him expect.

It stands to reason that the big guy doesn't usually appear later? Why did you directly explode the big move now?

Could it be that there is an even more surprising existence behind it?

It would be nice if you just got all the grains!

Hurry up and rummage through this leather bag now.

This leather bag is basically filled with relatively primitive soybeans.

In addition to that, there were some small, black seeds, I don't know what they were, Han Cheng couldn't recognize them.

At that moment, let people find a bamboo sieve, put all these soybean grains and pods into it, cherish the abnormality, and not even a single soybean was missed.

After waiting for a sieve, the black seeds mixed in are separated, and the soybeans are stored separately for use as seeds.

With these soybeans, slowly, the soybeans in the tribe can also develop into a scale!

After processing the soybeans, Han Cheng, who got off to a good start, went to open the second leather pocket with great expectations.
