The occurrence of this incident sounded a wake-up call for Han Cheng. Previously, he only thought about development but forgot about the safety of the tribe itself.

The safety of the tribe is the most important thing. Only when we are safe can we have the money to do more things.

It just so happens that the salt problem has been solved now, so there is basically enough pottery. Even if it is not enough, we can just use a few simple clay kilns to fire pottery. There is no need to rush to research and try new pottery firing technology, we can take it slow.

Han Cheng decided to focus all his work on building the wall.

Otherwise, you would be very scared when you go out to pee at night, for fear that a wolf would suddenly jump out and push you over!

The idea of ​​building a wall was decided, but how to build it became a problem.

It is said that walls built with bricks are the strongest, but given the current conditions in the tribe, it is simply not realistic to burn bricks in large quantities.

Since bricks are not available, we can only use adobes to build the wall, but the wall built with adobes is not strong.

Moreover, making adobe bricks requires a lot of effort. If the main force of the tribe, such as the eldest brother, does not take action, it is not known whether the remaining old, weak and sick people can build the wall in two years!

Human hands! This is a hoop around the neck of the tribe!

What was extremely simple in later generations has become a huge project here!

If you want to solve the problem fundamentally, you have to think about the root cause.

Han Cheng can be sure that, based on his prestige in the tribe, the witch and the eldest brother will not object to his proposal to build a wall, and will be happy to support it. However, they are powerless because the eldest brother and others still need to go hunting to find enough food for the tribe.

Only when this condition is met can we make adobe bricks and build walls.

If Han Cheng wanted to have enough labor, he needed to free his senior brothers from the heavy task of finding food every day.

In order to fish it out, Han Cheng needs to solve the food problem...

But the key is that this food problem is not easy to solve!

The only crop that can barely be considered a food grain is rapeseed, which is the primitive kind. However, there is still no land to grow rapeseed.

As for animal husbandry, there are only two rabbits and five baby rabbits that have not yet opened their eyes. The group of deer are not yet at the stage where they can be kept in captivity, but they can be killed for meat. With these dozens of deer, the tribe will not have to worry about food for at least one or two months.

But Han Cheng still couldn't bear to kill them like this.

What a wonderful herd of deer! Killing them like this... The animal husbandry industry, which had just started to show some promise, is about to fall into the abyss again...

So far, planting and animal husbandry have not even reached the stage of seedlings. It is simply impossible to count on these two things to solve the urgent problem.

Han Cheng is very depressed now. He has nothing what he wants!

Han Cheng suffered from insomnia again at night and did not fall asleep until the second half of the night.

After getting up in the morning, Han Cheng went to Yanshan accompanied by his senior brothers.

It happened that Uncle Lu and his little brother were here today. When he saw the "two-legged beasts" that he hadn't seen for a few days, Uncle Lu was actually a little nervous and took the initiative to greet Han Cheng, and then...

Then he put his mouth directly to the clay pot on Han Cheng's waist.

Well, Uncle Lu was not thinking about Han Chenggong, but the salt water that Han Cheng brought.

These days, Han Cheng has spoiled Uncle Deer's mouth. Accustomed to drinking purified salt water, it finds it difficult to swallow the rough stone wall that has all kinds of flavors.

After all, Uncle Lu is also a very elegant and prestigious person.

Han Cheng stretched out his hand as usual and gently stroked Guanghua's face and horns as Uncle Lu was drinking water.

Uncle Deer's tail was wagging happily, which showed how happy he was.

As for being touched on the face, would the other deer say that he was a gigolo and couldn't make it in the deer world? The arrogant old deer was not afraid at all, because his group of younger brothers, under his leadership, all joined the ranks of selling their faces and drinking salt water...

After drinking the salt water, Uncle Lu still habitually put his mouth close to Han Cheng. Han Cheng did not dodge this time, but let Uncle Lu's wet mouth rub the water on half of his body.

Han Cheng touched its face with his hand, and after a while, he smiled and said, "Let's go!"

Then he called the eldest brother and others who had fed the other deer to go back.

After much thought, I decided that I couldn't do anything to these deer, at least not now...

Today Han Cheng taught everyone some new characters, one of which is called "wall".

The most studious stone raised his hand and asked, "Son of God, what is a wall?"

"A wall is something made of wood, earth, or stone that can keep wild animals out and protect us from being attacked by wild animals."

Han Cheng gave the definition of "wall" according to what he had thought of before.

"With a wall, we don't have to worry about being bitten by wolves when we go out to pee at night, right?"

Xing is still frightened by the fact that her brother Chen was attacked by a wolf. When she heard Han Cheng explaining the wall, she immediately raised her hand to speak.

After she finished speaking, the other children did not laugh, because this question was not funny at all to them. They had to be on guard against the wild animals that they regarded as food and would also regard them as food.

Especially for children, the threat posed by wild beasts is no less than that of disease.

Han Cheng nodded seriously.

"Son of God, lead us to build the wall. We are not afraid of getting tired!"

After receiving Han Cheng's affirmative answer, the children looked at Han Cheng with bright eyes full of hope.

"Build! We must build the wall!"

Han Cheng nodded and spoke solemnly to the children.

In front of Han Cheng were several sticks that were more than one meter long and about two centimeters in diameter. He had specially asked his senior brother and others to bring them back on the way back from Yanshan.

Now that the eldest brother and his men have gone out hunting again, the tribe has suddenly become a lot quieter.

He was surrounded by the children he taught.

Everyone looked at the Son of God intently, expecting him to build a wall that could keep the wild beasts out.

Han Cheng cannot break such a stick now, but there are other things in the cave that can do the same thing.

Because of the improved diet, increased salt intake, and more exercise, Bo is now much stronger than before.

Especially his arms, which look particularly strong because they are used more frequently due to the stiffness of his legs.

Han Cheng chose half of these sticks and made a mark about every 25 centimeters, asking Bo to break them at the mark.

This kind of thing was not difficult for Bo. He took the wooden stick and exerted force with both hands. With a "crack", the stick broke at the mark.

The fracture is relatively neat because before breaking the hand, Han Cheng had someone use a stone knife to cut a shallow cut around the mark.
