The Qingque tribe is not big, and Han Cheng is the focus of the entire tribe, the kind that comes with his own flash.

Everything that happened to him, unless deliberately concealed, would soon become known to everyone.

The Son of God was going to make a tool that could be used to pound rice without human effort. This was something beyond everyone's cognition and was more "new and strange", so it didn't take long before everyone in the tribe knew about it.

The people who were most happy to hear such news were naturally those who often pounded rice in the tribe. They were naturally happy that they no longer had to pound rice all day.

But after the joy, I was also wondering what that thing that could pound rice without any effort looked like.

But I racked my brains but couldn't figure it out.

Not only them, many people in the tribe also thought about it in their hearts, but the result was the same.

In their opinion, this thing is completely impossible to happen.

However, over the years, the Son of God has made so many "impossible" things happen, so they don't really believe that the Son of God can't do it.

But it’s okay now. More people are going to the carpenter’s room. They all want to see what the tools made by the Son of God and Lame are like.

Among those who went to watch, the stonemason Mu Tou was not included, because he had something else to do.

At this moment, he was hammering on a stone with a hammer in one hand and an iron chisel in the other.

From time to time, there would be small pieces of stone flying and stone powder rising.

The body, face, hair...are all covered with a layer of whitish stone powder.

Mu Tou ignored all this and just focused on his work.

He was wearing a white, extremely thick mask that covered his nose, mouth and half of his face.

At first, Mu Tou felt uncomfortable wearing this thing and wanted to take it off, but the Son of God did not allow him to do so, saying that he might get sick, so he did not dare to take it off.

After a long time, he got used to it, and now he will wear a mask whenever he makes stone tools.

What he is making now is a stone mortar, which is very similar to the original one in the tribe.

However, the speed of construction is many times faster than the original one.

Because the previous mortar was chiseled out bit by bit with stone, while this one has an iron chisel and a hammer, so the speed is naturally incomparable.

For a long time thereafter, his job was to chisel mortars.

It’s not that his speed is particularly slow, but because there are a lot of mortars that need to be chiseled, at least five.

Mu Tou also knew the purpose of these stone mortars. They were related to the tools that the Son of God was making that could be used to pound rice without the need for humans.

Mu Tou also wanted to see the tool that made him equally curious as soon as possible, so he worked very hard on the mortar.

"Mu Tou, stop for a moment and go to the river to install the mortar."

Han Cheng came over and shouted beside him.

Mu Tou put down the tools in his hand and patted a stone mortar beside him, meaning that he had finished one.

He bent down and tried to move it, looking very strenuous. Second Brother came over, picked it up and walked away.

The wood suddenly became light.

He followed the team as they walked forward, looking at the strange-looking long piece of wood being carried by Heiwa and the eldest senior brother.

The wood was a peeled tree trunk, thick at one end and thin at the other.

The thick end is more than 20 centimeters in diameter, and the thin end is about 15 centimeters.

A hole was drilled in the middle of the thick end, and a wooden stick that was thin at the top and thick at the bottom was installed inside the end, forming a 90-degree angle with the tree trunk.

This wooden stick looks very similar to the stick used for pounding rice in the tribe.

A hole was also chiseled out horizontally in the middle of the trunk, towards the thick end.

Behind the hole, the top of the tree trunk was hollowed out, making it look like a tribe's canoe that had been shrunk countless times.

Mu Mu looked at the strange-looking thing and was confused for a moment. He didn't understand how this tree trunk made like this was used.

Can you use a tree trunk like this to automatically pound rice?

Such doubts lingered in his mind, and many people had similar thoughts to Mu Tou.

Even though the Son of God and Lame had already made the tools, they still couldn't figure out how to use these strange-looking things.

Han Cheng did not explain much, but led his men all the way to the river.

Stop a little upstream from the brick kiln.

Here, there is a tributary that flows into the small river. The water flow is not strong, and there is a height difference of about one meter between the tributary and the small river, which is just right for placing the simple water mill he made.

He measured here for a while, and asked the second senior brother to put down the mortar.

Then the strange-looking tree trunk was also placed there, and the special wooden stick under the big head was placed in the mortar.

The thin end extends toward the drop in the stream.

When the distance is about right, use the prepared crossbeam to pass through the horizontal hole in the tree trunk.

Two small walls were built with stones on both sides of the horizontal bar to support the wooden bar.

Because the front of the trunk was heavy, when the horizontal bar was raised, the rear end was lifted high and the front end hit the mortar.

Han Cheng walked to the end of the tree trunk, pulled it down, then loosened his hands, and the unbalanced crossbar fell again.

The wooden stick installed under the thick end hit the stone mortar, making a somewhat hollow sound.

The effect was pretty good, and Han Cheng nodded with some satisfaction.

When the people watching around saw Han Cheng's operation, their eyes lit up, and they seemed to understand how this thing worked all of a sudden.

But this enlightenment soon disappeared, and new doubts arose in my mind.

This method of pressing people down seems to be possible in the tribe, right? Why did the Son of God want to transport these things to the river?

And it doesn’t look like people don’t need to exert any effort, right?

Han Cheng saw the confusion among the crowd and just smiled without further explanation.

Instead, they asked a few lame men to nail three sticks in a line between the tree trunk and the water flow of the tributary.

The distance between the sticks is half a meter.

Then take a piece of bamboo, which is specially selected and is the thicker kind.

And the joints have been opened.

One end of the bamboo was placed at the drop of the tributary of the stream, and the other end was aimed at the end of the erected tree trunk.

As soon as the bamboo was placed, water flowed through it, crossed a distance of more than one meter, and fell into the wooden trough that had been dug out behind the trunk.

The water flow was not too fast, but by the time the lame men fixed the bamboo tubes on the wooden stakes nailed there, the water in the trough was already full...
