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

Just as he was about to ask him what was the matter, he had already left everyone and hurried to the courtyard.

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

This is really a person who has three urgencies, and as soon as he is in a hurry, his potential is immediately stimulated......

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

The frightened thing was this large mass of bugs, and he was relieved because he had even guessed that his bet was right.

The second senior brother's stomach is not a tumor that cannot be imagined at all in this era, but a parasite.

Poisonous bright grass with strong toxicity, effective against parasites!

The people of the Qingque tribe such as Wu and Senior Brother were shocked, they couldn't understand why there were so many worms in the stomach of good people!

The second senior brother, who was even weaker by the parasite and the poisonous bright grass, fell asleep, and did not continue to take the juice from the roots of the poisonous bright grass.

This thing is too toxic to be taken continuously, and the greatest possibility of continuous use is that the second senior brother and the parasites in the stomach will die together!

Liang squatted there in a circle, looking at the few poisonous bright grasses in front of him.

There was excitement and abruptness in his eyes.

Unexpectedly, I can't imagine that the poison that made me suffer so much and almost didn't lose my life can be used to treat diseases and save people in addition to being able to kill people!

It turns out that poisons can also be good medicine if they are used well......

He crouched here and thought excitedly, vaguely feeling as if he had caught something.

While Liang was excitedly feeling, Han Cheng, who had eaten one less bowl of rice at night, also gathered several senior brothers together and held a small meeting.

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

The worm in the stomach of the second senior brother frightened Han Cheng.

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

The proposal was quickly agreed.

Not only him, but Wu, Senior Brother and others were all frightened by what happened to Second Senior Brother and those terrible bugs.

How can there be these life-threatening things in the stomachs of good people?

As for the stomach ache after eating poisonous bright grass, then it hurts for a while, it is better than sleeping and eating.

The people of the Qingque tribe, if they don't get some poisonous bright grass to eat now, they will feel uncomfortable.

It's a bit of a big brother's demeanor.

The next day, Han Cheng and Liang carefully took the juice from the roots of the poisonous bright grass together, and then put it into the bowls that served the rice.

Put it very carefully, the amount of adults is less than what I got with the second senior brother yesterday, and the amount of children is divided into several grades according to their age.

You have to be careful with this thing, if you don't get it right, it's something that can kill people.

Han Cheng and Bai Xuemei also ate some.

So on this day, the Qingque tribe was full of stomachaches.

The effect was obvious, and twenty-two people were found to have parasites in their stomachs.

However, it is far less terrifying than the second senior brother.

These twenty-two people will also take Poison Bright Grass several times in the future, and strive to eliminate all the parasites in their stomachs.

After experiencing this parasite turmoil, the people of the Qingque tribe have become more serious and careful about drinking cooked water, not eating cold food and raw meat, washing hands frequently and paying attention to hygiene.

After taking Poison Bright Grass twice, the second senior brother's condition improved, although he was still relatively thin and weak, his spirit was much better than some time ago, and he was not so stunned.

Han Cheng's heart finally let go, and he was able to settle down and make hoes.

Without metal, bone, wood and stone are still the main materials used to make hoes.

Compared with the bone hoe, the manufacture of the bone hoe is more difficult.

Although it is difficult to grind and drill holes of bones, with the presence of people from the original bone tribe who are good at making bone tools, they can also slowly get it out, and the most important thing is that the polished bone hoe is not strong.

"Click......"

A crisp sound, with the tremor of the hoe handle, came clearly.

The corners of Han Cheng's mouth twitched, and he didn't need to look at it to know that the bone hoe he had just made was scrapped again.

He lifted his hand up, and the handle of the bone hoe was easily picked up by him.

However, the bone hoe, which was attached to the wooden handle, did not rise together, but remained in the earth.

It is still broken from the place where the drill hole pierced the wooden handle.

Han Cheng sighed, the bones were still not strong enough, they couldn't withstand too much force, it was okay not to use it to plow the ground, as long as it was used to plow the ground, after the bone hoe was dug into the soil, it was lifted hard, and after a few blows, the upper part of the bone hoe would not be able to withstand the force and would break.

Han Cheng snorted, it seems that this bone hoe can only be used for weeding in the future, and it is impossible to use it for plowing.

Ploughing the ground, a variation of the hoe - a pickaxe or a three-tooth nail rake is more efficient to use and more convenient than a bone shovel.

The so-called pickaxe is similar to a hoe, but the difference is that it is heavier than a hoe, and narrower and longer than a hoe.

With such a tool, it is easy to dig into the soil.

The three-tooth nail rake, because of the low resistance and sharpness, is also a very good tool for clearing wasteland.

Not to mention the three-tooth nail rake, it can only be built with steel.

Wood can also be made, but it is only a silver-like wax spear head, which is used to plow the ground, and it can be explained in three or two clicks, which is cleaner than a bone shovel.

So the only thing that can be considered is the head.

After a series of previous experiments, Han Cheng had already understood that the bones could only be made by hoeing grass and loosening the soil, but not plowing the ground.

In the limited conditions, the only material that could be used was the stone.

According to the shape that Han Cheng drew on the ground with a tree branch, the first stonemason of the Qingque tribe spent three days beating a hard stone into stone strips that were five centimeters wide, twenty centimeters long, and three centimeters thick.

These things, the very patient wood is not afraid at all, as long as he continues to do it little by little, he can always do it well.

But there was one thing that made it difficult for him, and that was to cut a hole through the wooden handle in the upper part of the hammered stone.

Cutting holes in the stone, wood has not been done before, you only need to use another piece of relatively sharp and strong stone to dig on it persistently and carefully, and after a long time, you can make a hole.

But the ones he had chiseled before were all relatively thin flakes of stone, and he had never been chiseled for a stone as thick as he was now.

And Miko also has an additional requirement, this hole should not only be chiseled large, but also as far as possible so as not to affect the firmness of the whole stone strip......
