I am a Primitive Man

While breaking the stick, Han Cheng made a mark on the remaining part of the stick at a place about half a meter away.

Then arrange these sticks side by side, and take out another straight stick to use as a ruler. The half-meter-long imprint marked on the stick on the farthest side shall be used as a straight stick. The stick used for the ruler is laid horizontally according to this mark.

After finding the right position, Han Cheng pressed the 'straightedge' with one hand to keep it from moving, and held a relatively sharp and small 'stone knife' with the other hand to draw down the 'straightedge'.

After the 'straightedge' was taken away, a mark appeared neatly on the same position of the neatly arranged tree sticks.

Han Cheng didn't let people move these sticks, but picked up the tree stick on the far side that was used as a ruler, aligned its half-meter end with the second marked half-meter, and then Make a second half-meter mark on the second stick against the half-meter mark on it.

Then put the first stick back in its original position and join the other sticks in the line.

Han Cheng picked it up again as a ruler and used the stick to move horizontally at the second and a half meters above the stick. According to the previous method, after finding the level, he pulled it down along the 'straightedge' horizontally.

In this way, two and a half meters are marked on each stick.

Regardless of whether Han Cheng's estimation of the distance of half a meter is accurate, the distance drawn in this way must be the same.

This also ensures that these tree sticks will be the same length after they are cut out.

After he made the best mark, the children around the side started to work together, each of them took a marked stick, and according to the method taught by the Son of God, he held a stone knife in his hand and cut around the mark. Make a shallow trace, which can ensure that the incision made by the lame fold is relatively neat to the greatest extent.

The sticks were folded, one pile was long and the other was short. These people, including the witch who heard the movement, were very curious about how the Son of God planned to use such a thing.

Could it be possible to build a wall that keeps the beasts out with these little sticks?

Han Cheng didn't say much, but started to pick up four short wooden sticks and form them into a square with a side length of about 25 centimeters.

The interface is wrapped tightly with rope grass.

Han Cheng made two square boxes of the same size.

After the two square frames were completed, he took out four long wooden sticks and connected them to the two square frames respectively. After the four wooden sticks were tied firmly, a rectangular parallelepiped frame made of wooden sticks appeared. .

A few primitive women sitting not far away have a pile of dried rope grass beside them, and they are twisting three rope grass together to form a rope according to the method taught by Shenzi earlier.

The rope grass is tough at first, and the three strands are twisted together to form a thin rope, which is even stronger.

Such a rope can lift more than ten catties of bacon!

About rubbing the rope, Han Chengcheng explained it when he got up in the morning, so now, they have rubbed a lot.

Han Cheng picked up a twisted straw rope and started to weave around one end of the rectangular frame. A net caught inside.

Such openings can ensure that fish swim in but cannot get out.

That's right, Han Cheng is making fish cages now.

Of course, such a small thing cannot build a fence, but it can provide a strong guarantee for the construction of a fence!

As long as dozens of fish cages are made, with the number of fish in the small river outside, the people in the tribe will not have to worry about food for a long time.

Once the food problem is solved, people will naturally come to build the wall.

After completing the innermost mechanism that allows the fish to enter but not exit, Han Cheng began to weave nets on the other five sides of the fish cage except for the opening.

The size of the mesh is based on the fact that Han Cheng's entire palm can just be put down. In this way, the fish caught in the fish cage must be at least seven or eight.

Han Cheng doesn't want to catch fish that are too small. After all, fish have only one life, so they should be of greater value.

It is also a fish, one catty is enough for a child, and five catties is enough for two adults.

Han Cheng called this the value of life.

Weaving this layer of net outside the fish cage is a labor-intensive job. Fortunately, Han Cheng has not done much work during this period of time, and he has the capital in his hand. Otherwise, after weaving this fish cage, he must Grinding out blisters is not possible.

In the afternoon, when the sun moved to the west about halfway, the fish cage was built.

Han Cheng pressed around hard to confirm that the fish cage was firm and there were no flaws, then picked up a rope that was thicker than ordinary straw ropes, and tied one end of it to a wooden stick at the mouth of the fish cage. real.

This rope is twisted out by the same method as the three strands of grass rope that weaves the fish cage. With it, the fish cage was lifted halfway out of the water, and then the rope broke, not only the fish ran away, but also the fish cage things basically don't happen.

The last step was finally done. While Han Cheng heaved a sigh of relief, he was also faintly excited. It was time to go fishing soon!

Different from Han Cheng's excitement, Wu Wu and these children were puzzled. They didn't understand how this thing that can be easily picked up with one hand can defend against wild animals, and why the wall mentioned by the body looks so unreliable ?

Han Cheng saw their doubts and knew that they had lost their minds, so he shook his head with a smile and said, This is not a wall, but a fish cage for catching fish.

Everyone is absolutely down, such a result is really unexpected!

You said that you just kept saying that the wall must be made, but after working for a long time, you came out with something that had nothing to do with building the wall.

They don't understand what fishing has to do with building walls.

There was a thoughtful look in Wu's eyes, and he vaguely understood Han Cheng's thoughts.

However, if it is really what he thinks, then this strange thing, which he has never heard of before, and which is called a fish cage by the son of God, must be able to catch a lot of fish. The fish cage can catch at least as many fish as two people with harpoons.

Han Cheng handed the fish cage to Hei Wa and asked him to hold it for him, then took Wu's hand, and together with Wu they led the crowd to the small river.

Because of the presence of wolves, the people who came out basically had weapons in their hands.

The elder brother even picked out two women from the hunting team and asked them to stay in the tribe to strengthen the tribe's defense during the day and protect everyone's safety.
