Han Cheng used a fire poker to pick up the firewood in the brazier. The flames soon became much brighter and the scene in front of him became clearer.

He looked at it carefully for a while and finally confirmed that the rapeseed-like thing on the mulberry branch was silkworm seeds, although the color was different from the seeds laid by the silkworms he raised as a child.

He thought he had caught nothing after the golden silkworm emerged from its cocoon, but he never expected that he had accidentally caught its sons.

This is good, as it saves him the trouble of going to the mulberry tree to look for it again in the spring of next year. Thinking of the feeling of being bitten by the mulberry tree, he couldn't help but grin.

After looking at the silkworm seeds carefully for a while, the firewood in the brazier was about to burn out and the light became dim.

Han Cheng had no intention of adding more firewood. He stood up and put the mulberry branch back to its original place. Taking advantage of the last light of the fire, he came to the kang, untied the animal skin belt, lay on the kang, and covered himself with the animal skin...

There was no trouble last night. Even if the people of the Bone Tribe wanted to do something, the presence of people on the high walls would make them completely give up the idea.

The next morning, the people of the Bone Tribe went to the Green Bird Tribe to borrow fire, preparing to heat their food outside the wall. After eating, they set off back.

They also brought tools for drilling wood and retrieving the fire, but it was too troublesome. It would be more convenient to borrow fire from the Green Bird Tribe. After all, there would always be a bonfire burning in the tribe.

The leader of the Bone Tribe who came to borrow fire showed an extremely surprised look, because the Green Bird Tribe, which had a lot of fire yesterday, now did not even have a spark!

After seeing the appearance of the leader of the Bone Tribe, the eldest brother couldn't help but feel proud again. He called Huoyi and asked her to drill wood to make fire for the people in the neighboring tribe. It happened that their Qingque tribe also needed to make a fire to cook.

When the leader of the Bone Tribe saw that the eldest brother was actually preparing to drill for fire, and that the person who was going to make fire was a very old man, he didn't know what to say for a moment.

After hesitating for a moment, he waved his hands repeatedly, indicating that they did not want to borrow the fire anymore, and just ate some fruits and went back.

What I was thinking was, if such an old man were to rub wood together to make fire, wouldn't it be like having to wait until dark before any flame would come out?

The eldest brother held him back and shook his head.

At this time, Huoyi had already prepared the tinder and picked up the hand drill and started drilling.

The leader of the Bone Tribe was stunned when he saw this unique way of making fire by drilling wood. Shouldn't he rub the sticks quickly with his palms? This...

His doubts were soon replaced by shock, because even as he was stunned, smoke was already rising from the tinder...

The sky was a little gloomy and the sun did not appear as expected. The leader of the Bone Tribe led the people of the Bone Tribe, carrying or lifting the precious pottery they had exchanged, and rushed towards their own tribe.

They walked in a hurry, worried that it would rain. Getting wet in this season would be no joke.

He held the jar of salt in his arms. The jar was no longer the original one that contained salt, but the one they exchanged for food. The tribe did not give him the original jar of salt.

The implication there is clear, that is, the salt can be shared, but the jar must not be free.

The leader of the Bone Tribe seemed a little dazed as he walked hurriedly. He was not dissatisfied because the other party only gave him salt but not a jar, but he was recalling everything he had seen in that tribe.

There were pottery, walls, houses, deer, and delicious salt... Those would have been fine, but how could a man that old easily make fire?

Everything he saw in that tribe had a great impact on him, and he couldn't help but wonder whether their traditional way of survival also needed to be changed?

Do I need to build a wall for my own tribe as well?

The image of the people from that tribe appeared in his mind again, standing on the high wall, holding stones and stone spears, looking down from above.

If my tribe also had such a wall, I wouldn't have to worry about wild animals running into the cave and hurting people. When I left the cave to hunt, I could bring more people with me...

only…

Thinking of the tall and majestic appearance of the wall, he became hesitant again. Can this really be built by humans?

The people of the Bone Tribe left, and life in the Green Bird Tribe returned to normal.

The eldest brother was sorting the food brought from the Bone Tribe into different categories so that they could be eaten later.

By the time he had finished preparing these things, breakfast in the tribe was also ready.

Shang, who used to have a good appetite, has no appetite today.

In fact, he didn't enjoy his meal last night. After taking a few bites, he would look towards the three tiled houses where the Son of God lived, looking like he was worried.

He suddenly sped up his eating speed, emptied the food in the bowl in a few bites, put the bowl into a large ceramic basin filled with water not far away, and went out of the cave to where Han Cheng lived.

Han Cheng didn't eat much this morning. After dinner, he left the cave and returned to his room.

“Knock, knock, knock.”

Shang came to the door, hesitated for a while, and finally raised his hand and knocked on the closed door.

Knock on the door. This was Han Cheng's specific instruction. Although he would not do anything too shameful in the room, it was still necessary to knock on the door to remind others before they came in as it was his own private space.

"Come in."

The voice of the Son of God was heard from within the room. Shang seemed a little nervous as he pushed open the door and walked in, then turned around and closed the door.

Han Cheng had already come out of the inner room. He was a little surprised to see that it was Shang who came, because Shang had never come to see him before. The two people who came to his room most often were Wu and the eldest senior brother.

The room in the middle is used as a living room. In the middle, there is a stone pier built with stones and wood ash, and on the pier is a two-foot square, relatively flat stone slab. Although it is simple, it looks like a stone table.

Around the stone table, there are several wooden blocks or straight-shaped stone blocks, which are used as stools.

Han Cheng naturally sat in the main seat and let Shang sit opposite him, although until now, Han Cheng had not explained the rules here to everyone in the tribe.

After sitting down, Han Cheng asked Shang what was the matter.

Facing the Son of God's question, Shang seemed a little nervous. He himself was a little strange and didn't understand where his nervousness came from, because the Son of God had always been a very kind person...

He hesitated for a moment, but finally spoke and told Han Cheng his thoughts in Mandarin, which was not very fluent.

Han Cheng understood what he meant. It was similar to what Han Cheng thought yesterday, that is, when the people of the Qingque tribe go out again in the future, they must leave a certain number of people behind to guard the tribe and not let the tribe be too empty.

After hearing this, Han Cheng nodded and praised. This kind of behavior that cares for the tribe must be encouraged.

Shang was very happy to see that the Son of God did not blame him and agreed to his proposal. The worry that had been hanging in the air since last night finally made him feel relieved.

Han Cheng nodded as he watched Shang leave. As expected of a former leader, his knowledge was indeed better than that of ordinary people. Of course, this also had a lot to do with his previous experiences.

Han Cheng pondered for a while in the room, then went out and found Wu and his senior brother to talk about this matter. Both of them agreed with it, and the decision on the tribal security issue was made.
