I am a primitive

It's not that Bai Xuemei has it, but that he has a way to drill holes in rocks.

Bai Xuemei, who was sleeping soundly, was woken up by Han Cheng's voice, and asked Han Cheng what happened in a daze.

Han Cheng smiled and hugged her upstairs, said it was all right, and let her continue to sleep.

Bai Xuemei, who was hugged by Han Cheng, felt relieved and soon fell asleep.

Han Cheng didn't sleep. If it wasn't midnight, he would run out and start working according to the method he thought of.

Unable to sleep at night, and holding a child bride-in-law in his arms, Han Cheng's hands will certainly not be idle.

Han Cheng is now deeply impressed by his wisdom and foresight.

After changing her name to Bai Xuemei, the place where the child's bride-in-law should grow flesh finally began to grow flesh.

Although the scale is small and young, but at least it is not a flat river.

Chanting Yang Wanli's famous poem "The little lotus just showed its sharp horns, and the dragonfly stood on its head a long time ago", Han Cheng fell asleep.

I had a dream all night, I can't remember the plot or anything, I only remember Snow White's pair of proud weapons.

Quietly lifted the fur covering his body and looked at Bai Xuemei in his arms. Han Cheng, who was still immersed in his dream, immediately pulled back to reality...

The whole Qingque tribe was a sensation, because not long ago, their clever, wise, kind, and god sons with a series of adjectives suddenly announced in a high-profile manner that he would use wood to drill holes in stones Come.

After confirming from the Son of God that the wood and the stone are two people from their Qingque tribe, that is, the real wood and stone, everyone immediately boiled.

Drilling holes in wood with hard stones can still be said in the past, but now Shenzi turned one by one and drilled holes in stones with wood?This is really unimaginable!

Some people were afraid that their guess would be wrong, so they found a wooden stick and drilled it on the rock. After half a day, except for the redness of the palm of the hand, there was nothing to gain.

After someone replaced the hand drill with a pure wood drill pipe, he started to drill the head, but the result was also ineffective.

The stone is safe and sound, but the wooden drill pipe has been worn away for a long time.

After these two experiments, everyone became more curious and confused about it, and felt that the wisdom of the Son of God was unfathomable.

In the anticipation of everyone, Han Dashenzi, who had done enough foreplay, walked confidently with a calm smile, and came to the stone bar chiseled out of wood.

In his hand, he carried a bag made of animal skin.

Everyone's eyes were firmly fixed on the pocket, expecting their Son of God to take out amazing tools from it.

The pocket was opened, and under the unblinking gaze of everyone, Han Cheng took out a tool from it.

The people who were looking forward to it almost fell down after seeing this tool.

One by one, they all looked at each other in blank dismay.

This... Isn't this a hand press drill?I and others have verified that it is impossible to drill the stone.

How did the Son of God take it out?

This this…

Could it be that the son of God is going to drill the hole with a hand press drill?

That's right, Han Chengcheng was going to drill the hole with the tool in his hand.

Han Cheng, who suddenly wanted to pretend to be a little aggressive in the tribe, was very satisfied with everyone's reaction.

He squatted there, adjusted the hand drill, and started working.

-------------Chapter Dividing Line---------------

Everyone in the Qingque Tribe stared at Han Cheng's every move with wide eyes, especially those who drilled through rocks with their hands, and refused to blink.

They wanted to see how the Son of God drilled holes out of the stone with a method that they had tested and confirmed was not feasible.

On one side of the stone strip on the ground, there is a hole dug out by the wood before.

Han Cheng put the drill pipe of the adjusted large hand drill into this not deep pit.

Instead of drilling directly, he first grabbed a handful of things from his leather pocket and put them into the pit.

This thing is sand.

Han Cheng didn't have the magical method of turning stones into gold, and other people in the tribe could not get out with simple sticks, and he couldn't get out either.

But add some finely divided sand to it, and everything will be different.

It wasn't something he came up with on a whim.

When he was a child, he had two stone mills at home, and his family used these stone mills to grind sesame oil and sold them in the surrounding Zhuangzi.

He often plays at the oil mill, and he heard this method from chatting with the older generation.

It is said that long ago, this method was used to drill holes in stone mills.

Of course, it is unknown to Han Cheng whether he drilled by hand or not.

Granite stones with a thickness of almost ten centimeters can be drilled through, let alone a stone strip with a thickness of three centimeters.

This is why Han Cheng dared to boast about Haikou without even doing half of the experiments.

"Chichi~"

"Chichi~"

As Han Cheng moved up and down, the wooden drill began to rotate back and forth, squeezing the sand in the pit, rubbing against the stone bars, and making teeth-stinging sounds.

The pebbles in the river will lose all their edges and corners and become so smooth because of the erosion of the river.

In addition to water, rivers also carry fine sand, which is the most critical thing.

Seeing all this, the people of the Qingque Tribe showed a look of sudden surprise, not because they understood the truth, but because they had a clear realization like 'the Son of God really didn't use the hand press drill alone'.

Compared with drilling wood, the diamond head is much slower.

After changing the sand that was crushed by friction three times in a row, the effect can finally be seen.

The pit got a little deeper, and the uneven walls that had been chiseled by wood around it also looked a lot more glamorous.

Mu Mu, who was squatting by the side, saw with bright eyes, the new method that Shenzi came up with was much faster than what he had used before!

When chiseling with stones, the speed is relatively fast at the beginning, but as the hole gets deeper, the speed will plummet.
