The eyes of the people of the Qingque tribe widened, staring closely at Han Cheng's every move, especially those who had personally drilled through the stones with their hands, and they refused to blink their eyes.

They wanted to see how the Son of God had drilled holes in the stone by methods that had been tested by them and determined to be unworkable.

On the side of the stone strip on the ground, there is a pit that was previously hewn out of the wood.

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

Instead of drilling directly, he grabbed a small handful of things out of his leather pocket and put them in the pit.

This thing is sand.

Han Cheng didn't have the immortal means to turn stones into gold, and other people in the tribe couldn't drill out of it simply with wooden sticks, and he couldn't drill it either.

But add some fine sand to it and everything will be different.

This thing 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 them to grind sesame oil and sell it to the surrounding Zhuangzi.

He often played at the oil mill, which he heard from the older generation when they were chatting.

It is said that a long time ago, this method was used to make holes in the stone mill.

Of course, whether it is a hand pressure drill or not, this Han achievement is unknown.

Almost 10 centimeters of granite can be drilled through, let alone a 3-centimeter thick stone bar.

This is also where Han Cheng dared to boast about such a Haikou when he didn't do half an experiment.

"Whoa~"

"Whoa~"

As Han Cheng pressed up and down, the wooden drill began to spin back and forth, squeezing the sand in the stone pit, rubbing against the stone bars, making some tooth-aching sounds.

The pebbles in the river lose all their edges and become so smooth because of the river's washing.

In addition to water, rivers also carry fine sediment, which is the most important thing.

The people of the Qingque tribe who looked at all this showed a sudden look, not that they understood the truth of this, but that they had an understanding like 'Shenzi really didn't use a hand-pressed drill alone'.

Diamond heads are much slower than drill wood.

After changing the sand that had been crushed three times in a row, I was finally able to see the effect.

The pit has become a little deeper, and the uneven walls around it, which were originally hewn out of wood, are much more polished.

Squatting on the side of the wood, his eyes lit up, and the new method that Miko had come up with was much faster than the one he had used before!

When chiseled with stones, the speed is relatively fast at first, but as soon as the pit is deep, the speed plummets.

And you have to be on guard at all times not to chisel things.

This is not the case, the deeper the pit, the faster it will be drilled, and there is no need to worry about the stones below shattering.

Moreover, it is more convenient to press the drill by hand than to hold the stone chisel with your hand.

Don't doubt why the wood knows so much, because the hand-pressed drill is in his hands at this time......

With these initial results, the people of the Qingque tribe had completely believed what Han Cheng said about drilling holes in the stone with wood.

The next day, the hole in the stone bar was completely drilled, and it was a very round hole.

Put the wooden handle that has been prepared before, put it into the hole, and then use a wooden wedge to wedge it tightly, and a pickaxe is finally ready!

The angle between the wooden handle and the stone pickaxe is about 70 degrees, which allows the lever principle to work, allowing more soil to be 'trapped' and with less effort.

After Han Cheng personally demonstrated, this hammer head was in the hands of the senior brother.

"Poof!"

Under the watchful eyes of everyone, the head raised by the senior brother fell and went directly into the soil, more than ten centimeters deep.

The elder brother's hand holding the handle of the hammer lifted up, and the hammer that sank into the dirt lifted a large piece of dirt.

This time, it takes almost three times to dig a bone shovel!

The people of the Qingque tribe who witnessed the easy use of the head were very excited.

Miko had described the golden millet dream to them more than once, and they were deeply fascinated by it.

Now that they have such a sharp tool as the hammer, they have more confidence to plant attractive millet around the tribe......

Everything is difficult at the beginning, and with the first successful manufacturing head, it becomes much easier to expand production.

From the people of the original bone tribe, find three people who often make bone tools, and let them knock stones with wood.

Knock out stone strips that are about 5 wide and 3 thick and about 20 long.

A few more people were dispatched to chisel with a special hand-pressed drill and cut holes in a sharper stone strip at the end.

In order to reclaim land on a large scale, it is necessary to allocate a part of the manpower to produce tools that are conducive to reclamation.

When the Qingque tribe is in full swing to seek development and pursue a better life, there are also things happening in other places that cannot be seen.

"Whoa!"

There was a sound of breaking water, and in the midst of the splashing water, a very rudimentary fish cage woven by tree strips broke through the water and tilted on the grass on the shore, and a half-long fish jumped out of it.

It can't live without water, and wants to jump into the water as soon as possible, and then enjoy the legendary fish and water.

"Smack!"

Two large palms suddenly appeared, grabbed it, and slammed it to the ground.

It stopped moving after jumping twice, looking at the water close at hand, and didn't bat at a glance.

A primitive man with animal skins and leaves on his body picked up the fish, which could no longer enjoy the joy of fishing, and threaded a branch through the gills of the fish, and made a string with three or four other fish.

With that, he threw the rudimentary fish cage back into the water and began to wait.

Not far behind him, there was a fire that was gradually extinguishing, and there were some fish bones on the side of the fire.

The primitive man stood here and looked at the fish cage that had been immersed in the bottom of the river for a while, then squatted down, picked up the water in his hand and began to wash his face.

It was a habit he had cultivated in the tribe that had left him with infinite fond memories.

The cool water of the river carried away the dust from his face, and through the slightly swaying reflection, the man's appearance could be discerned, although his beard and hair had grown.

This man is the bark of the tree that has been expelled from the Blue Sparrow tribe and is thought to be dead.

The bark that had washed his face, squatted by the river, looked at his own reflection in the water, and began to think back to what had happened to him during this period of time.

At first, he thought he was going to die.

Homeless, he wandered around the Blue Sparrow tribe for a while, and finally left the fascinating, dream-like tribe.

Not knowing where he was going, he walked in a daze until he returned to his original tribe.
