Everyone in the Qingque tribe widened their eyes and stared closely at Han Cheng's every move, especially those who were drilling stones with hand drills, who refused to even blink.

They wanted to see how the Son of God drilled a hole in the stone using a method that they had tested and found to be unfeasible.

On one side of the stone slab on the ground, there was a hole that had been dug out by wood.

Han Cheng placed the adjusted large-sized hand drill rod into the shallow pit.

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

This stuff is sand.

Han Cheng didn't have the magical ability to turn stone into gold. Other people in the tribe couldn't drill a hole with wooden sticks, and he couldn't do it either.

But if you add some fine sand in it, everything will be different.

This was not something he came up with on a whim.

When he was a child, his family had two stone mills, which they used to grind sesame oil and sell in nearby villages.

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

It is said that this method was used to drill holes in millstones a long time ago.

Of course, Han Cheng has no idea whether it was a hand drill.

A millstone can drill through granite that is almost ten centimeters thick, let alone a stone strip that is only three centimeters thick.

This is also the reason why Han Cheng dared to make such a boast without 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 pit and rubbing against the stone bars, making some teeth-grinding noises.

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

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

The people of the Green Bird tribe who were watching all this showed a look of sudden realization. It was not that they understood the reason behind it, but that they had an epiphany that "the Son of God really does not only use hand-operated drills."

Compared to drilling wood, the speed of a diamond head is much slower.

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

The pit became a little deeper, and the surrounding walls, which were originally uneven due to being chiseled in the wood, also looked much smoother.

Mu Tou, who was squatting on the side, watched with shining eyes. The new method the Son of God had come up with was much faster than the one he had used before!

When using a stone chisel, the speed is faster at the beginning, but once the pit gets deeper, the speed will drop sharply.

And you must always be on guard not to break anything.

This method is different. The deeper the pit, the faster you can drill, and you don't have to worry about the rocks below breaking.

Moreover, using a hand drill is more convenient than chiseling a stone with your hands.

Don't wonder why Mu Mu knows so much, because the hand drill is in his hand at this time...

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

On the second day, the hole in the stone slab was completely drilled through, a very round hole.

Insert the wooden handle that has been prepared earlier into the hole, and then use wooden wedges to wedge it tight around it, and the hoe is finally ready!

The angle between the wooden handle and the stone hoe head is about seventy degrees, which is conducive to the principle of leverage, allowing it to "catch" more soil and save effort.

After Han Cheng demonstrated it personally, the hoe fell into the hands of the eldest brother.

"puff!"

As the crowd watched, the hoe raised by the eldest brother fell down and went directly into the soil, more than ten centimeters deep.

The eldest brother lifted up the handle of the hoe, and the hoe, which was stuck in the soil, lifted up a large piece of soil.

This time, it takes about three strokes of the bone shovel!

The people of the Qingque tribe were very excited after witnessing with their own eyes how useful the hoe was.

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 a powerful tool like a hoe to turn the soil, they have more confidence to plant tempting millet around the tribe...

All things are difficult at the beginning. Once the first hoe is successfully made, it becomes much easier to expand production.

Find three people from the original bone tribe who often make bone tools, and let them knock the stone together with the wood.

Knock out stone strips that are about five inches wide, three inches thick, and twenty inches long.

A few more people were assigned to use a special hand drill to drill holes in the stone slabs that had one end sharpened.

If you want to do your work well, you must first sharpen your tools. In order to carry out large-scale land reclamation, it is necessary to allocate some manpower to make tools that are conducive to reclamation.

While the Qingque tribe was busy pursuing development and a better life, things were also happening in other invisible places.

“Crash!”

There was a sound of breaking water, and amidst the splashing water, a very simple fish cage woven from tree branches broke out of the water and tilted on the grass on the shore. A half-foot-long fish jumped out of it.

It cannot live without water, so it wants to jump into the water as quickly as possible to enjoy the legendary pleasure.

“Bang!”

Two big hands suddenly appeared, grabbed it, and threw it to the ground.

It jumped twice and then stopped moving, looking at the water so close to it, with its eyes wide open.

A primitive man, covered in animal skins and leaves, picked up the fish that could no longer enjoy sex, pierced its gills with a branch, and strung it together with three or four other fish.

After doing this, he threw the simple fish cage back into the water and began to wait.

Not far behind him, there was a dying fire with some fish bones beside it.

The primitive man stood here for a while and looked at the fish cage immersed in the river bottom, then squatted down, scooped up river water with his hands and began to wash his face.

This was a habit he developed in the tribe that left him with endless 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 was still recognizable.

This person was none other than Shuba, who had been expelled from the Greenbird Tribe and was believed to have died long ago.

After washing his face, Shuba 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.

After wandering around the Qingque tribe for a while, the homeless man finally left that fascinating, dreamlike tribe.

He didn't know where to go, and walked in a daze all the way, and finally returned to his original tribe.
