Chapter 324: Stone head and bark

The people of the Qingque tribe widened their eyes and stared at Han Cheng's every move, especially those who personally pressed the drill through the stone, and refused to blink their eyes.
They wanted to see how the son of God used the method that had been tested by them and confirmed that it was not feasible to get out of the stone.
On the side of the stone strip on the ground, there is a hole cut out by the wood.
Han Cheng put the drill pipe of the adjusted large hand drill into this not deep hole.
Instead of drilling directly, he grabbed a handful of things from his leather pocket and put it into the pit.
This thing is sand.
Han Cheng doesn't have the magical means of turning stones into gold. Other people in the tribe can't get out of sight with a wooden stick, and he can't get out either.
But by adding some finely divided sand to it, everything will be different.
He didn't come up with this thing on a whim.
When he was young, he had two stone mills at home, and the family used the stone mills to sell sesame oil to nearby villagers.
He often played at Youmo, this method was heard from the older generation when chatting.
It is said that this is the method used to make holes in the stone mill long ago.
Of course, it is not known whether this Han achievement was made by hand.
Almost ten centimeters of granite can be drilled through, not to mention the three centimeters of thin stone.
This is why Han Cheng dared to boast such confidence in Haikou when he didn't do half of the experiment.
"Chish~"
"Chish~"
As Han Cheng pushed up and down, the wooden drill began to rotate back and forth, squeezing the sand in the stone pit, rubbing against the stone strips, and making some sour noises.
The pebbles in the river lose all the 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 stunned look. It is not that they understand the truth, but that they have a kind of understanding like ‘God is not using a hand drill alone’.
Diamond heads are much slower than drilling wood.
After changing the sand that was crushed by friction three times in a row, the effect was finally seen.
The pit has become deeper, and the uneven walls that were originally chiseled by wood also appear to be a lot brighter.
Squatting on the side of the wood, his eyes were bright, and the new method that the son of God came up with was much faster than what he had used before!
Chisel with a stone is faster at the beginning, but when the hole is deep, the speed will drop linearly.
And be on guard at all times and don't gouge things.
This method is not the case. The deeper the pit, the faster the drill, and there is no need to worry about the rocks below being broken.
And pressing the drill by hand is easier than holding a stone chisel by hand.
Don’t doubt why wood knows so much, because the hand drill is in his hand at this time...
With these initial results, the people of the Qingque tribe had completely believed Han Cheng's claim of drilling holes in stones with wood.
On the next day, the hole in the stone bar was completely drilled, a very round hole.
Put the prepared wooden handle into the hole, and then use a wooden wedge to wedge it tightly around, and finally a shackle is ready!
The angle between the wooden handle and the stone shank is about seventy degrees, which is conducive to the use of the principle of leverage, which can ‘carry’ more soil and save effort.
After Han Cheng personally gave a demonstration, this yoke was in the hands of the master.
"puff!"
Under the crowd's onlookers, the head raised by the big brother fell and went directly into the soil, more than ten centimeters deep.
The big brother lifted the hand holding the handle of the shackle, and the shackle fell into the mud, and a large piece of mud was lifted up.
This time, you almost need to dig three times!
The people of the Qingque tribe who have witnessed the usefulness of the yoke are very excited.
The son of God has described the golden millet dream to them more than once, and they are deeply fascinated by it.
Now that they have a sharp weapon like the yotou, they have more confidence to plant all around the tribe with attractive grains...
Everything is difficult at the beginning. With the first successfully manufactured shank, it is much easier to expand production.
From the people of the original bone tribe, find out three people who often beat bone tools, and let them hit the stone with wood.
Knock out a stone strip that is about five in width and three in thickness and twenty in length.
A few more people were mobilized, and a special hand drill was used to drill a hole with a sharper stone.
If a worker wants to do his job well, he must first sharpen his tools. For large-scale land reclamation, it is necessary to allocate a part of the manpower and create tools that are conducive to reclamation.
When the Qingque tribe is full of enthusiasm for development and pursuing a better life, there are other things that cannot be seen.
"Wow!"
There was a sound of breaking water, and amidst the splashes of water, an extremely simple fish cage woven from tree stalks broke through the water, leaning 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 joy of fish and water.
"Snapped!"
Two big palms suddenly appeared, caught it, and slammed it to the ground.
It bounced twice and stopped moving, looking at the water close at hand, it couldn’t catch its eyes.
A primitive man surrounded by animal skins and leaves picked up this fish that could no longer enjoy the fun of fish and water, put a branch through the gills, and made a string with three or four other fish.
After doing this, he threw the simple fish cage into the water again, and then began to wait.
Not far behind him, there was a dying fire, and there were some fish bones on the side of the fire.
The primitive man stood here for a while and looked at the fish cage immersed in the river bottom~EbookFREE.me~ and then squatted down, picked up the river water with his hands and started to wash his face.
This is a habit he cultivated in the tribe that left him infinitely beautiful memories.
The cool river water took away the dust on his face. Through the slightly shaking reflection, you can see the appearance of this man. Although the beard and hair are long, he can still be recognized.
This person is the bark that has been expelled from the Qingque tribe and is believed to be dead.
The bark that had washed his face, squatted by the river, looked at his reflection in the water, and began to think about his experience this period of time.
At first he thought he was going to die.
Homeless, he finally left the fascinating and dreamlike tribe after lingering in the Qingque tribe for a while.
He didn't know where he should go, he walked in a muddle-headed way, and finally returned to his original tribe.
