Magu stone.

bite.

granite.

Boom.

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

Bang.

…

Inside the room, Han Cheng was checking the large and small stones that Shang, Mao and others had brought back.

He picked up a piece and looked at it carefully for a while, then threw it aside while muttering something to himself.

limestone.

Boom.

Han Cheng picked up another stone, identified it, and threw it aside out of habit. Then he came to his senses, quickly picked it up and put it aside.

This made everyone who were watching on the side with a sinking heart secretly breathe a sigh of relief. They finally found it, otherwise this trip would have been in vain.

They breathed a sigh of relief, but Han Cheng did not. He checked all the stones and did not see any trace of metal ore. Naturally, he could not relax.

"Son of God, this piece..."

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

What I mean is that Han Cheng doesn’t need to be sad, because there is still one piece left, right?

Han Cheng sighed slightly. Limestone is indeed a good thing, but that was in the past or in the future.

Now the tribe has wood ash as a substitute, and there is no place where lime is used on a large scale. For the current tribe, metal mines are the most important mineral resources.

Under such circumstances, he naturally couldn't be happy.

After learning from Han Cheng that the only piece of stone left was not a stone that could be used to refine metal, but a stone that could be used to burn cement, Wu and others were no longer happy.

Especially Shang and Mao, who had been running outside for a long time, lowered their heads in sadness.

Han Cheng then realized that something was wrong, and patted the limestone in his hand and said, "Good things are not easy to come by, and it is even more difficult to get good things like metal all at once.

Didn’t we also gain something this time?

"Mao, open the map and tell me where you got it."

Most primitive people have simple minds, and when they heard Han Cheng say this, they immediately felt much better.

Mao quickly took out a piece of nitrated, hairless animal skin.

On one side of the hide, several rough marks were carved with a sharp stone, and the marks were dyed black with charcoal.

On the edges of these traces, there are some circles that are not quite round.

The circle is also different.

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

This is the map drawn by the Trade Institute under the guidance of Han Cheng.

The black lines represent roads and the circles represent tribes.

A single circle means that the number of adults is less than 30, and two circles mean that the number of adults is between 30 and 60.

Although this map looks extremely simple, like a few irregular fruits growing on a few crooked branches, it has great significance.

At least we can have a general understanding of the locations of the surrounding tribes, and we won’t be in the dark like before.

Mao has a very good memory, 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, then his eyes began to search the map, and soon he pointed to a circle on the map.

Meaning that this is where the limestone is obtained.

Shang, who was traveling with them, felt a little dizzy. This time, they went to several tribes and exchanged a lot of things. He couldn't remember which tribe he got all these from.

While feeling dizzy, I had more admiration for the guy here who didn't have very strong fighting ability.

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

This way, when the tribe needs a large amount of limestone, they will know where to find it.

Shang and Mao's behavior of taking caravans out to trade can also be called a great geographical discovery of the Qingque tribe.

Through discovery and recording, the people of the Qingque tribe will become more familiar with the situation around the tribe.

After recording these, Han Cheng turned his gaze to another pocket, which contained various seeds that Shang and the others had exchanged.

The stones didn’t bring much surprise, but I wonder if there are any surprises inside these seeds.

It feels like a lottery draw.

He reached out and pulled a leather bag, untied the rope, and before Han Cheng could pour it out, some yellow beads rolled out.

When he saw these yellow balls, Han Cheng's eyes became serious.

A feeling of surprise and uneasiness instantly filled my heart.

He quickly picked up the yellow balls and held them in his hands, observing them carefully.

The whole ball is yellow, and there is a small brown spot on the back, like a narrow line.

It is not big, about one-third the size of soybeans in later times.

Han Cheng looked at it for a while, suppressed the growing joy in his heart, picked up a grain with slightly trembling hands, put it into his mouth, and chewed it slowly and vigorously.

Soon, the unique taste of raw soybeans filled the entire mouth.

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

Seeing Han Cheng's reaction, Wu, the eldest brother, Shang, and others also became happy. It seemed that they had found something good.

At that moment, Wu, the second most powerful man in the Qingque tribe, followed the steps of the first most powerful man, picked up a soybean and put it in his mouth, biting it slowly and laboriously with his gapped teeth.

I want to taste the taste of these seeds that even the Son of God, who is known for his picky taste, can eat them with a smile on his face.

The result was that the taste was not very good, neither sour nor astringent, but there was an indescribable taste that made people feel a little uncomfortable.

Han Cheng spat out the soybeans he had chewed into pieces, found some water to rinse his mouth, and the smile on his face became even more intense.

He had just opened the leather bag and was given such a big surprise, which was really beyond his expectation.

Logically speaking, shouldn't the big guys usually appear later? Why did they use their ultimate moves right away?

Could there be even more surprises to come?

It would be better if we could just gather all the five grains together!

He immediately searched the leather bag.

This leather bag is basically filled with relatively raw soybeans.

In addition, there are some small, black seeds. Han Cheng couldn't recognize what they were.

He immediately asked someone to find a bamboo sieve and put all the soybeans and pods into it, taking great care not to miss even a single soybean.

When you are ready, pass the soybeans through a sieve to separate the black seeds mixed in. Store these soybeans separately and use them as seeds.

With these soybeans, the soybeans in the tribe can gradually develop into a large scale!

After processing the soybeans, Han Cheng, who had a good start, came and opened the second leather bag with great anticipation.
