I am a Primitive Man

The second senior brother lying there suddenly got up from the kang, startling everyone.

Just as they were about to ask what was going on, he dashed into the courtyard, bypassing everyone in a hurry.

At this moment, Han Cheng realized what was happening and couldn't help but smile.

Sure enough, when people were in a hurry, their hidden potential would be immediately triggered...

Looking at the thing before him, Han Cheng felt nervous and relieved.

He was nervous because of the large mass of worms but relieved because his guess made half-blindly and half-aimlessly, turned out to be correct.

The second senior brother didn't have a tumor in his stomach, something unimaginable in this era; instead, he had parasites.

The highly toxic Poison Liang Grass was effective against parasites!

The people of the Green Sparrow Tribe, including the shaman and the eldest senior brother, were shocked and puzzled. They couldn't understand why a seemingly healthy person would have so many worms in his stomach!

The weakened second senior brother, tortured by parasites and Poison Liang Grass, fell asleep without taking any more juice from the roots.

This substance was too toxic to be taken continuously. The possibility of continuous use was that the second senior brother and the parasites in his stomach would perish together!

Liang squatted there, scrutinizing the several Poison Liang Grass plants before him.

Excitement and realization shone in his eyes.

He couldn't believe that the poisonous medicine that had caused him so much suffering and nearly cost him his life could not only be used to kill but also to treat and save lives!

When used properly, it turned out that even poison could become medicine...

As he squatted there, excitedly contemplating, he vaguely felt he had grasped something.

While Liang was excitedly reflecting, Han Cheng, who had skipped a meal that evening, gathered the shaman and the eldest senior brother for a small meeting.

The core of the meeting was to provide everyone in the tribe with some juice from the Poison Liang Grass.

The worms in the second senior brother's stomach had shocked Han Cheng.

Before he arrived, the people of the Green Sparrow Tribe had been drinking untreated water, sometimes containing invisible insect eggs.

This proposal quickly gained unanimous agreement from the people.

Han Cheng, the shaman, and the eldest senior brother were all frightened by the second senior brother's ordeal and the terrifying worms.

How could there be life-threatening things in a person's stomach?

As for experiencing stomach pain after consuming Poison Liang Grass, enduring a moment of pain was better than living in constant fear.

Now, if the people of the Green Sparrow Tribe didn't consume some Poison Liang Grass, they felt uncomfortable all over.

The next day, Han Cheng and Liang carefully extracted the juice from the roots of the Poison Liang Grass and added it to rice bowls.

They were cautious, giving adults less than they had given the second senior brother the day before and dividing the dosage for children into several levels based on their age.

This substance must be handled carefully, as it could be deadly if not properly administered.

Han Cheng and Bai Xue also consumed some.

So, on that day, the people of the Green Sparrow Tribe were all suffering from stomach pain.

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

However, it was far less terrifying than the second senior brother had experienced.

These twenty-two people would also need to consume Poison Liang Grass several times to eliminate the parasites in their stomachs.

After experiencing this parasite crisis, the people of the Green Sparrow Tribe became even more severe and meticulous about drinking boiled water, avoiding cold food and raw meat, washing their hands frequently, and paying attention to hygiene.

After taking the poison Liang grass two more times, Second Senior Brother's condition improved. Although still relatively thin and weak, his spirits were much better than before, and he wasn't as dazed anymore.

With this improvement, Han Cheng finally felt relieved enough to focus on making hoes.

Without metal, bone, wood, and stone remained the primary materials for making hoes.

Compared to bone shovels, making bone hoes was more difficult. Although bone grinding and drilling were laborious tasks, with the skilled bone craftsmen of the original Bone Tribe, they could slowly be accomplished. However, the most significant issue was that the bone hoes were not sturdy.

"Crack..."

With a crisp sound, accompanied by the tremor of the hoe handle, the fracture was clearly audible.

Han Cheng smirked slightly, knowing without looking that the newly made bone hoe had failed again.

As he lifted his hand, the bone hoe handle came off quickly. However, the bone hoe head connected to the wooden handle remained stuck in the ground, broken from where it was drilled.

Han Cheng sighed. The bone was still not sturdy enough to withstand too much force. While it was okay for weeding, once used for digging, the bone hoe would easily break after a few attempts to pry it out of the soil.

Han Cheng wrinkled his nose. It seemed that this bone hoe could only be used for weeding in the future; it was impossible to dig.

When turning the soil, a modified hoe like a mattock or a three-toothed nail rake was more efficient and handy than a bone shovel.

The so-called mattock was similar to a hoe but heavier, narrower, and longer, with substantial weight.

Such a tool could quickly turn the soil.

The three-toothed nail rake was excellent for breaking new ground due to its low resistance and sharpness.

Let's not talk about the three-toothed nail rake; it could only be made of steel.

Wood could also be used to make it, but it would only be a temporary solution, good for a few digs before it broke, cleaner and more efficient than a bone shovel.

So, the only option left was the ax.

After several experiments, Han Cheng understood that bones could only be used to loosen soil but not for digging.

With limited resources, only stones remained as usable material.

Following the shape drawn by Han Cheng on the ground with branches, the first stonemason of the Green Sparrow Tribe, Mu Tou, spent three days painstakingly hammering a hard stone into a strip five centimeters wide, twenty centimeters long, and three centimeters thick.

Mu Tou was patient with these tasks. As long as he continued bit by bit, he would eventually get it done.

However, one problem puzzled him: drilling a hole in the upper part of this hammered stone to fit a wooden handle.

Drilling holes in stones had been done before, using another sharp, sturdy stone to carefully drill it persistently. After a long time, a hole could be made.

But all the holes drilled before were in relatively thin stone pieces. Thick stones like the current one had never been drilled before.

Moreover, Han Cheng had additional requirements: the hole not only had to be large but also should not compromise the overall solidity of the stone strip...
