Everyone in the Qingque Tribe stared at Han Cheng's every move with their eyes wide open, especially those who drilled the stone with their own hand drills and refused to blink.
They wanted to see how the Son of God drilled holes into the stone using methods they had tested and confirmed to be unfeasible.
On one side of the stone strip on the ground, there is a hole carved out by the wood.
Han Cheng put the adjusted drill pipe of the large hand drill into the not-deep pit.
Instead of drilling directly, he first grabbed a small handful of something from his leather pocket and put it into the pit.
This thing is sand.
Han Cheng didn't have the magical ability to turn stone into gold. Others in the tribe couldn't drill out holes simply with sticks, and he couldn't drill them out either.
But adding some finely divided sand into it will make everything different.
This thing was not something he came up with on a whim.
When he was a child, his family had two stone mills. The family used these stone mills to grind sesame oil and sell it in nearby villages.
He often plays at Youmo, and he heard this method from chatting with the older generation.
It is said that a long time ago, this method was used to make holes for stone grinding.
Of course, it is unclear whether Han Cheng drilled it by hand or not.
A granite stone that is almost ten centimeters thick can be drilled through, let alone a stone strip that is only three centimeters thick.
This is why Han Cheng dared to boast about Haikou like this without even doing any experiments.
"Chichi~"
"Chichi~"
As Han Cheng pressed up and down, the wooden drill began to rotate back and forth, squeezing the sand in the stone pit, rubbing against the stone bars, and making some tooth-staining sounds.
The pebbles in the river will lose all their edges and become so smooth because of the erosion of the river.
In addition to water, rivers also carry fine sediment, which is the most critical thing.
Everyone in the Qingque Tribe looked at all this with a look of astonishment. It wasn't that they understood the truth, but they had a clear understanding like 'The Son of God really didn't use the hand drill alone'.
Compared with drilling wood, the diamond head is much slower.
After replacing the sand that was broken by friction three times in a row, the effect can finally be seen.
The pit has become a little deeper, and the surrounding uneven walls that were originally carved with wood also look a lot more glorious.
Mu Mu, who was squatting aside, looked at it with bright eyes. The new method that Shen Zi came up with was much faster than what he had used before!
Using stone to chisel will be faster at the beginning, but once the hole becomes deeper, the speed will plummet.
And you have to be on guard at all times not to break things.
This is not the case with this method. The deeper the hole, the faster it can be drilled, and there is no need to worry about the rocks below breaking.
And it is more convenient to press the drill by hand than to hold the stone with your hand.
Don't doubt why Mu Mu knows so much, because the hand drill is in his hand at this time...
With these initial results, everyone in the Qingque tribe completely believed what Han Cheng said about using wood to drill holes in the stone.
On the second day, the hole in the stone strip was completely drilled through, making it a very round hole.
Put the wooden handle that you have prepared before into the hole, and then use wooden wedges to wedge it around tightly. Finally, a hoe is ready!
The angle between the wooden handle and the stone hoe head is about 70 degrees, which is conducive to the lever principle and can 'hold' more soil and save effort.
After Han Cheng gave a demonstration in person, the hoe came into the hands of the senior brother.
"puff!"
Under the watch of everyone, the hoe raised by the senior brother fell and went directly into the soil, more than ten centimeters deep.
The elder brother lifted up the hand holding the handle of the hoe, and the hoe that had sunk into the soil lifted up a large piece of soil.
This time, it takes almost three digs with a bone shovel!
The people of the Qingque tribe, who witnessed the usefulness of the hoe with their own eyes, seemed very excited.
The Son of God had described the golden millet dream to them more than once, and they were deeply fascinated by it.
Now that they have tools like the hoe to plow the ground, they have more confidence to plant attractive grains around the tribe...
Everything is difficult at the beginning. Once the first hoe is successfully manufactured, it will become much easier to expand production.
Among the people of the original bone tribe, find three people who often make bone tools and ask them to knock stones with wood.
Knock out a stone strip about five inches wide, three inches thick, and twenty inches long.
A few more people were mobilized to use a special hand drill to chisel and make holes in the stone strips with a sharper end.
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 some manpower to make tools that are conducive to reclamation.
While the Qingque tribe is in full swing and focused on developing and pursuing a better life, there are also things happening in other invisible places.
"Wow!"
There was a sound of breaking water, and amid the splashing water, a very simple fish cage woven from tree strips broke out of the water and leaned on the grass on the shore. A half-length fish jumped out of it.
It cannot live without water, so it 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, grabbed it, and threw it to the ground.
It jumped a few times and then stopped moving. It stared at the water just around the corner without closing its eyes.
A primitive man, whose body was wrapped in animal skins and leaves, picked up this fish that could no longer enjoy the pleasure of fish and water, passed a branch through its 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 began to wait.
Not far behind him, there was a gradually extinguishing fire, and there were some fish bones beside the fire.
This primitive man stood here for a while and looked at the fish cage submerged in the river bottom. Then he squatted down, picked up the river water with his hands, and began to wash his face.
This is a habit he developed in the tribe that left him infinite fond memories.
The cool river water took away the dust on his face, and through the slightly swaying reflection, the man's appearance could be seen. Although his beard and hair had grown longer, his appearance could still be recognized.
This man was none other than Bark, who had been expelled from the Qingque tribe and was considered dead long ago.
After washing his face, Bark squatted by the river, looked at his reflection in the water, and began to think about what he had experienced during this period of time.
At first he thought he was going to die.
Homeless, he lingered in the Qingque tribe for a while, and finally left that fascinating, dream-like tribe.
He didn't know where he was going, so he walked in confusion along the way, and finally returned to his original tribe.
