When breaking the tree stick, Han Cheng took the remaining part of the stick and made a mark about half a meter away.

Then place these sticks side by side, and take out another straight stick to use as a ruler. Use the half-meter-long mark on the outermost stick as the standard, and place the stick used as a ruler horizontally according to the mark.

After finding the right position, Han Cheng held the 'ruler' with one hand to prevent it from moving, and with the other hand he held a relatively sharp and small 'stone knife' and cut along the 'ruler'.

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

Han Cheng did not let anyone move these sticks. Instead, he picked up the tree stick at the edge that was used as a ruler, aligned its half-meter end with the second half-meter marked end, and then compared it with the half-meter mark on it and made a second half-meter mark on the second stick.

Then put the first stick back to its original position and put it together with the other arranged sticks.

Han Cheng picked up the stick and used it as a ruler and placed it horizontally at the second half meter of the stick. Following the previous method, after finding the right level, he pulled it down horizontally along the "ruler".

In this way, two and a half meter marks were made on each stick.

Regardless of whether Han Cheng's estimate of the half-meter distance is accurate or not, the distance drawn in this way must be the same.

This ensures that the sticks are of the same length after being cut.

After he had finished marking it, the children who were gathered around started to work together. Each of them took a marked stick and, according to the method previously taught by the Son of God, used a 'stone knife' in their hands to cut a circle of shallow marks around the mark. This would ensure that the incision of the limp would be relatively neat to the greatest extent possible.

The sticks were folded, some were long and some were short. These people, including the witch who came after hearing the noise, were very curious about how the Son of God was going to use such a thing.

Can a wall that can keep wild beasts out be built with just these small sticks?

Han Cheng didn't say much, but began to pick up four short wooden sticks and arrange them into a square with a side length of about twenty-five centimeters.

Tie the interface tightly with rope and grass.

Han Cheng made two 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 tying the four sticks tightly, a rectangular frame made of wooden sticks appeared.

Several female primitive people were sitting not far away, with a pile of dried rope grass beside them. They were twisting three rope grasses together into ropes according to the method taught by the Son of God.

Rope grass is tough by nature, and when three strands are twisted together into a thin rope, it becomes even stronger.

A rope like this can hang more than ten kilograms of bacon!

Han Cheng had instructed them about the rope-twisting task in the morning, so by now they had already made a lot of them.

Han Cheng picked up a twisted straw rope and began to weave it around one end of the rectangular frame. After a while, a net appeared at the square at this end. The net had a large front, a small opening at the back, and was sunken into the square.

Such an opening can ensure that fish can swim in but not out.

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

Such a small thing certainly cannot be used to build a wall, but it can provide strong protection for the construction of the wall!

As long as they make dozens of fish cages, relying on the number of fish in the river outside, the people in the tribe don't have to worry about food for a long time.

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

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

The size of the mesh is just enough to fit Han Cheng's entire palm. In this way, the fish caught with the fish cage must weigh at least 70 or 80 grams.

Han Cheng doesn't want to catch fish that are too small. After all, fish only have one life, so they should make the most of it.

The same fish, a one-pound fish is only enough for a child, while a five-pound fish is enough for two adults.

Han Cheng calls this the value of life.

Weaving the net outside the fish cage is a rather strenuous job. Fortunately, Han Cheng has worked a lot during this period and has some money in hand, otherwise, his hands would be covered with blisters after weaving this fish cage.

The fish cage was completed when the sun had moved about halfway westward in the afternoon.

Han Cheng pressed around hard to make sure that the fish cage was solid and had no leaks. Then he picked up a rope that was thicker than an ordinary straw rope and tied one end of it to a wooden stick at the opening of the fish cage, securing it securely.

This rope is twisted in the same way as three-strand straw rope used to weave fish cages. It is extremely strong and with it, it is virtually impossible for the fish to escape while the cage is halfway out of the water and then the rope breaks and the cage is lost as well as the fish.

The last step was finally completed. Han Cheng breathed a sigh of relief, but also felt a little excited. It was soon time to fish!

Unlike Han Cheng's excitement, Wu and the children were confused. They didn't understand how this thing that could be easily lifted with one hand could protect against wild beasts. Why did the wall called by the body look so unreliable?

Han Cheng saw their confusion and knew that they were all thinking the wrong thing, so he smiled and shook his head and said, "This is not a wall, it's a fish cage, used to catch fish."

Everyone was stunned, this result was so unexpected!

You said that you had just kept saying that you must build the wall, but after working for half a day, you ended up producing something that has nothing to do with building a wall.

They didn't understand what fishing had to do with building a wall.

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

However, if it was really as he thought, then this strange-looking thing that he had never heard of and that the Son of God called a "fish cage" must be able to catch a lot of fish. At the end of the day, the number of fish caught by a fish cage must be at least as many as the number caught by two people with harpoons.

Han Cheng handed the fish cage to Heiwa and asked him to hold it for him. Then he took Wu's hand and led everyone to the river together with Wu.

Because there were wolves around, most of the people who followed out had weapons in their hands.

The eldest brother even picked out two women from the hunting team and asked them to stay in the tribe to strengthen the tribe’s daytime defense and protect everyone’s safety.

(I saw others say that this chapter can be marked as featured, but I searched for a long time but couldn't find where to do it... Please forgive me, a half-baked author. I also invite all book friends to speak freely. If you have any good ideas or need to complain, you can say it. I will make appropriate adjustments according to the situation, and I will also adopt some good suggestions 😄 Thank you everyone.)
