"Wow~"

"Dang!"

The water in the bamboo tube is constantly flowing, and more and more water is stored in the sink behind the trunk.

As the water continued to pour in, this side became heavier and heavier, and the originally upturned part began to slowly descend downward.

At the other end of the trunk, a thick stick, also left the mortar.

When the water in the sink became more abundant, the trunk was finally completely out of balance.

The sink fell sharply, and the water inside spilled out.

Then the thick end of the trunk rose high, paused slightly, and then fell abruptly.

The wooden stick embedded in the trunk of the tree hits the stone mortar with a "dang" sound.

The principle of this thing is very simple, in fact, it is a seesaw that is often played.

The difference is that the people at both ends of the seesaw are replaced with water and thick wood itself.

In this way, as long as water is constantly poured into it, this simple water mill will work tirelessly.

Of course, the real sense of the water mill is not like this, but relies on the erosion of the water flow to drive the shaft, and then the things on the shaft drive the wooden pole to lick the rice.

It's just that this kind of water is too complicated, and Han Cheng and Lame fiddled with it for a few days, feeling that it could not be completed in a short time.

After thinking about it for a while, Han Cheng found another way to come up with this extremely simple water shoe.

Of course, such a water mill is just a transition, and the attempt to make a complex version of the water mill will continue.

Because this simple version of the water mill can only be used to scoop rice or smash some other things, while the complex version of the one, as long as it is based on the water mill and slightly changed, it can be used to drive the stone grinding, and Han Cheng naturally will not give up.

The people of the Qingque tribe who were gathered on the side looked at the water scoops that were raised and smashed from time to time under the continuous injection of water, and their eyes widened one by one.

That's how this tool works?

Ordinary water, and such a function?

After the surprise, a sense of sudden enlightenment rose in my heart.

Water could indeed be used in this way, but they couldn't think of it until the Son of God had completely done it.

"Let's get some millet and try it."

Han Cheng looked at the people around him who looked a little stunned and surprised, and said.

Because I said when I came, I came to experiment and make a good water mill, so I carried millet.

At this time, after hearing Han Cheng's voice, Zhuang who often licked rice hurriedly brought a jar over.

Taking advantage of the gap between the slowly rising water mills, three bowls of millet were filled into the stone mortar.

Then the people stood together and waited to see the result.

The water flowed and filled the sink, and the water rose and fell, smashing into the stone mortar.

This really doesn't require human effort, you only need to do the later cleaning work, which is really very light.

A few people who often cook rice are very happy when they look at the smashed and shelled millet in the stone mortar.

But the joy didn't last long, because they found a problem.

That is, the speed of this water mill is too slow, they lick rice at a normal speed, and they lick it five times in a row, and this water mill can't lick it for a while.

Labor-saving is labor-saving, but this speed is too touching, right?

With such water, can the people of the tribe eat the millet that rushes to the rice at the end of the day?

This......

More and more people realized this problem, and the people of the Qingque tribe, who had been happy for a long time, soon became a little silent.

Wu's brows were also a little tightened, this water mill was indeed exquisite, but in terms of the speed of the rice, it was indeed a little too slow.

Thinking like this in his heart, it didn't take long for Wu's brows to suddenly relax.

Because he remembered what Wood had been doing for the past few days.

There is more than one piece of wood for the stone used to chisel the mortar.

In other words, there is not only one water bowl that the Son of God wants to install.

Although the speed of a water mill is not as fast as that of a person, but if you want to install three or four or more, won't the speed of the rice come up?

Moreover, this water mill relies on the power of the water flow, and it is tireless at all, and the speed will not slow down, unlike people who will get tired after a while.

In this way, this water mill is very useful!

Thinking like this, Wu looked around, the terrain here is open, and it is not a problem to install three or four more water sinks.

I have to say that Wu, the original first wise man of the Qingque tribe, was not in vain.

While many people were still puzzled, he had already figured out what was inside.

Wu who figured things out, the more he thought about it, the more happy and excited he became.

Seeing that his face was still confused, he raised his voice softly, ready to share the matter with everyone.

"I have a word, please listen quietly!"

Of course, this is not what Wu said, but Han Cheng, who was standing on the side, made up his own brain after noticing Wu's movements.

Wu does not have the momentum of Prime Minister Zhuge , and the people of the Qingque tribe will naturally not be sprayed by his hearty heart attack.

But the effect is still there.

After Wu's words, everyone suddenly understood, and even more of them reacted as fiercely as strong, picked up their own slaps and slapped them directly on the head.

Yes, a water mill can't compare to the speed of a person's rice, so wouldn't it be enough to put up a few more?

I can't figure it out for such a simple thing.

There are still many things they can't figure out, and when Han Dashenzi let the limp tie a through bamboo pole to the other side of the three pillars, the speed of patting his head, like a water mill, has become faster.

Two bamboo poles are poured into the sink at the same time, and the time between the water poles falling together is directly shortened by half.

That is to say, according to the current frequency, three water mills can exceed the normal speed of one person's rice.

Moreover, the wooden stick used to scoop rice under the water mill is thick, and the stone mortar below is also larger than the stone mortar used to scoop rice by hand, so that more millet can be scooped out at one time.

In the waiting of everyone, the millet in the stone mortar was gradually broken through its shell.

Seeing this, the red Zhuang and blue flowers on the door of his head were ready to go over and get out the good millet in the stone mortar to clean up, but Han Cheng shouted.

After adding another bamboo pipe, the water mill speed became faster, and the time interval in the middle was not enough for people to get the millet inside.

If you do this, it is easy to get injured by the water bully.

Han Cheng found a wooden pillar that he had ordered someone to bring before, and when the water mill was raised, he stood near the horizontal bar and supported the trunk of the tree, so that the water mill would not fall, and Zhuang and Qingcao could rest assured that they could boldly get the millet out and clean up the millet in the stone mortar, so as not to be too panicked.

After the grain was reloaded in the stone mortar, and the standing trees underneath were put down, the water mill continued to work tirelessly......
