The second senior brother who was lying there suddenly got up from the kang, scaring everyone.

Just as I was about to ask him what was going on, he had already pushed through the crowd and hurriedly ran into the yard.

Han Cheng realized what was going on at this time and couldn't help but smile.

This is indeed the case. Once you get anxious and angry, your potential will be immediately stimulated...

Looking at the thing in front of him, Han Cheng was both frightened and secretly relieved.

What made me tremble with fear was the huge group of bugs, but I was relieved because my guess was right.

What was in Second Brother's stomach was not a tumor, something that was simply unimaginable in this era, but a parasite.

The highly toxic poison grass is effective against parasites!

Wu, the eldest brother and other people from the Qingque tribe were horrified. They couldn't understand why a healthy person had so many worms in his stomach!

The second brother, who was tortured by parasites and the poison grass and became even weaker, fell asleep and did not continue to take the juice from the roots of the poison grass.

This thing is too toxic and cannot be taken continuously. The biggest possibility of taking it continuously is that Second Brother will die along with the parasites in his stomach!

Liang squatted there and looked around at the several poisonous grasses in front of him.

There was excitement and realization in his eyes.

I never thought that the poison that caused me so much pain and almost killed me could be used to cure diseases and save lives, besides killing people!

It turns out that poison, if used properly, can also become a good medicine...

He squatted here and thought excitedly, vaguely feeling that he seemed to have grasped something.

While Liang was excitedly gaining insights, Han Cheng, who had eaten one less bowl of rice in the evening, also called together Senior Brother Wu and several others for a small meeting.

The core of the meeting was to give everyone in the tribe some juice of the poisonous grass to eat.

Han Cheng was frightened by the worms in Second Brother’s stomach.

Before he came, the people of the Qingque tribe had always been drinking raw water, and sometimes there were invisible insect eggs in the water.

This proposal was quickly unanimously agreed upon by everyone.

Not only him, but Wu, the eldest brother and others were all frightened by the experience of the second brother and those terrible insects.

How could such deadly things be in the stomach of a healthy person?

As for the stomachache caused by eating poison grass, just let the pain last for a while. It is better than having trouble sleeping and eating.

The people of the Green Bird Tribe would feel uncomfortable if they didn't eat some poisonous grass.

He has a bit of Dali Ge's style.

On the second day, Han Cheng and Liang carefully took the juice from the roots of the poisonous grass and put it into bowls filled with rice.

I put it in very carefully. The adult portion is smaller than what I made with my second brother yesterday. The amount for children is divided into several levels according to their age.

You have to be careful with this thing, it could be fatal if you're not careful.

Han Cheng and Bai Xuemei also ate some.

So on that day, everyone in the Qingque tribe suffered from stomachaches.

The effect was obvious, and another 22 people were found to have stomach parasites.

But he is not as scary as the second brother.

These twenty-two people will have to take the poison grass several times in succession in the future to try to eliminate all the parasites in their stomachs.

After experiencing this parasite crisis, the people of the Green Bird tribe became more careful and attentive about drinking cooked water, not eating cold food or raw meat, washing their hands frequently and paying attention to hygiene.

After taking the poison grass twice more, the second brother's condition improved. Although he was still thin and weak, he was in better spirits than before and was not as dazed as before.

Han Cheng finally felt relieved and was able to concentrate on tinkering with the hoe.

Without metal, bones, wood and stone are still the main materials for making hoes.

Compared with bone shovel, bone hoe is more difficult to make.

Although grinding and drilling bones are difficult and time-consuming, they can be slowly accomplished with the presence of people in the proto-bone tribe who are good at making bone tools. The most important thing is that the ground bone hoe is not strong.

“Crack…”

A crisp sound was clearly heard along with the vibration of the hoe handle.

Han Cheng's mouth twitched. He knew without even looking that the bone hoe he had just made was scrapped again.

He raised his hand and easily picked up the handle of the bone hoe.

However, the bone hoe connected to the wooden handle did not rise up, but remained in the ground.

It still broke at the place where the wooden handle was drilled.

Han Cheng sighed. His bones were still not strong enough and could not withstand too much force. It was fine if he did not use them to dig the ground. As soon as he used them to dig the ground, after the bone hoe dug into the soil and lifted it up with force, it would not take more than a few times before the upper part of the bone hoe could not withstand the force and broke.

Han Cheng sniffed. It seemed that this bone hoe could only be used for weeding in the future. It was impossible to use it to dig the ground.

For turning the soil, a variation of the hoe - a pickaxe or a three-toothed rake - is more efficient and easier to use than a bone shovel.

The so-called hoe is similar to a hoe, but the difference is that it is heavier, narrower and longer than a hoe. It is a tall and thin thing with weight.

Such a tool can easily dig into the soil.

The three-toothed rake is a very good tool for clearing land because it has little resistance and is sharp.

Not to mention the three-toothed rake, which can only be made of steel.

It can also be made from wood, but it is just a silver wax spear head, which can be used to dig the ground. It only takes a few strokes to do the job, and it is cleaner and more efficient than a bone shovel.

So the only thing we can consider is the hoe.

After a series of previous experiments, Han Cheng has realized that bones can only be used to weed and loosen the soil, but cannot dig the ground.

Under limited conditions, the only material available was stone.

According to the shape Han Cheng drew on the ground with a tree branch, Mu Tou, the first stonemason of the Qingque tribe, spent three days hammering a piece of hard stone into a stone strip that was five centimeters wide, twenty centimeters long and three centimeters thick.

Mu Mu, who is very patient, is not afraid of these things at all. As long as he does it step by step, he can always do it well.

But there was one thing that troubled him, and that was how to chisel a hole in the upper part of the hammered stone slab for the wooden handle.

Drilling holes in stone and wood has been done before. All you need to do is use another sharp and solid stone to chisel on it carefully and persistently. Over time, you will be able to drill a hole.

But what he had chiseled before were all relatively thin flakes of stone. He had never chiseled stone as thick as the one he was chiseling now.

The Son of God also had an additional requirement: the hole should not only be large, but also should not affect the firmness of the entire stone bar as much as possible...
