Heiwa and the others didn't know what the Son of God wanted to do, but they followed him out with great interest, because usually in such circumstances, the Son of God could perform new miracles.

The winter here is colder than the place where Han Cheng lived in later generations. Although the sun has come out a long time ago, the temperature has not risen much. Several people walked out of the Qingque tribe, and white mist was spewing in the air, like monsters swallowing clouds and spitting out smoke.

Han Cheng first asked someone to dig a rectangular pit here with a bone shovel.

The pit doesn't need to be too deep, twenty centimeters will be enough.

Although the weather was cold, the ground was not frozen because it had not rained or snowed for a while. It was still possible to dig with a bone shovel, but my hands were a little cold.

Exercise makes people warm. After a shallow pit about one meter long and half a meter wide was dug, the people who participated in the digging were already sweating.

Everyone was guessing the purpose of the Son of God digging a hole here.

Are we going to set up another line of defense here?

Seeing that this place is not too far from the defense zone made of sticks, thorns and vines, I think this is most likely the case.

However, this idea soon disappeared from everyone's mind, because the pit was too narrow and could be crossed with just a little effort, so it was of no use at all to stop the enemy.

After the pit was dug, Han Cheng was about to ask people to proceed to the next step, but he heard someone in the tribe calling for dinner.

Eating is the most important thing in the world. This is the creed of foodies. Especially in such a cold season, drinking a bowl of hot soup can make people feel comfortable all over.

Han Cheng immediately stopped what he was doing and returned to the tribe with everyone else to have dinner.

We just finished eating a batch of rabbits this morning, so today’s lunch will naturally be mainly rabbits.

After drinking a bowl of steaming rabbit soup, all the coldness was dispelled, and my body felt warm. I held a golden roasted rabbit leg, slowly biting and chewing it. It was so comfortable.

After lunch, Han Cheng filled half a clay pot with the remaining charcoal from cooking, and led his men out of the cave, which was used as a storage room and dining hall, and walked towards the outside of the tribe.

This time, more people followed. In addition to Heiwa and his friends who had dug holes in the morning, Wu, who had had enough of knocking rabbits, also came out, as well as those little kids who were jumping around and not afraid of the cold.

Tietou, Mu Tou and Qi Balloon came out and looked here for a while, then turned and headed east.

Under their arms, they held stone sickles and ropes with hooks for tying things.

This kind of rope is most convenient for tying things. Pull up both ends of the rope placed on the ground in advance, wrap it around the firewood, rapeseed or other things on it, then hang the end without the wooden hook on the wooden hook, and pull it hard in the opposite direction.

Tietou and his men climbed up the hill where the cave was located, took out the rope and stretched it out on the ground, and then began to cut with stone sickles.

They harvested the thatch when it was completely dry.

Before tiles were safely popularized, thatch has always been a very useful grass. This year the thatch is growing very well, so Han Cheng naturally doesn't want to waste it, as he still has a great use for it.

It’s just because the Qingque tribe had too much to do, and they had to wait until now to find someone to do this.

The thatch was golden in color, and when it collided with each other on the ground, a 'crackling' sound was heard.

Those who were arranged by Han Cheng to harvest thatch were people who often harvested green grass. Doing one thing for a long time made them very familiar with using stone sickles to harvest things.

The fastest one is still Tietou, the lawn mowing enthusiast. Before others have finished tying a bundle, he has already started tying the thatch.

Half-kneeling, he pressed one leg on the bundle of straw. Every time he pressed, the hand holding the end of the rope pulled hard.

As he exerted force, the gap that had just been squeezed out by his legs disappeared. After doing this several times in a row, the whole bundle of straw was tied firmly. The extra rope ends were tied to the taut rope so that the bundle would not loosen. Then a rough straw rope made of fur was used to tie another bundle along the rope. After it was tied firmly, the rope with the hook was untied.

This is done to save rope. After all, it is a waste to use such well-woven rope to tie up thatch.

However, the rough ropes woven from thatch are inconvenient to tie, and it takes a lot of effort to tie the thatch tightly and not let it loose. This method can solve this problem perfectly.

This method was not thought of by Han Cheng, but was figured out by Tietou himself.

Sure enough, labor can make people smarter.

However, it was Han Cheng who came up with the idea of ​​tying a wooden hook at one end of the rope commonly used to tie grass.

When tying at the beginning, make a loop at one end of the rope, wrap it around, then pass the other end of the rope through the loop and pull it in the opposite direction.

The process is the same as using a grooved rope.

But this has many inconveniences. The rope can easily get stuck when untying the bundle. Another problem is that if you pull it too many times, the ring will be worn off.

Tietou was very distressed because the rope was always breaking. In order to prevent the rope from breaking, he didn't dare to use force when tying things.

The result is even more troublesome. If the grass is not tied tightly, it will be very uncomfortable to transport. Sometimes, the bundle will loosen before you can walk far, and the tied grass will slide to the ground...

Han Cheng didn't pay attention to it at first, but found something wrong after two or three days, because in the past Tietou was always full of energy after mowing the grass, and his hay bales were very neat, but now he was like a different person.

After asking the reason and knowing the whole story, the rope with wooden hook came into being.

Wooden hooks are not afraid of being worn by the rope. The more they are worn, the stronger they become, and they will also become smoother.

After Han Cheng solved this problem, Tietou's enthusiasm for mowing the lawn was rekindled...

While Tietou was tying up the thatch, Han Cheng was directing people to use bone shovels to fill the pit with the soil that had been dug out in the morning and piled on the edge of the pit.

Inside the pit was a pile of burning wood.

Everyone had no idea what the Son of God meant by this. Not to mention lighting a fire in the wild, why... did he have to cover up the fire with dirt?

In this way, wouldn't the fire be completely extinguished?

Although everyone was confused, their hands did not stop moving. They shoveled up the dirt one shovel at a time. The burning fire was quickly extinguished by the sudden blow. Before they could even struggle, they were buried alive.

After burying the body, Han Shenzi was still not satisfied, so he had people jump on the body and stompling the soil to make it firm.

It was almost as ferocious as when Niu Jinda buried Shan Xiongxin's troops alive and then led three thousand cavalrymen to trample on them for half the night.

Until now, everyone was still confused about what the Son of God wanted to do. Wu had been thinking about it for a while, but he still couldn't guess what the Son of God meant by this move.

Of course they couldn't guess it, because even Han Cheng, the instigator, himself had no idea whether this seemingly unreliable method could produce carbon.
