“Crash~”

"when!"

The water in the bamboo tube continued to flow, and the water stored in the trough behind the tree trunk increased.

As the water continued to pour in, this side became heavier and heavier, and the originally raised part began to slowly fall down.

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

As more water filled the tank, the tree trunk finally lost its balance completely.

The sink suddenly dropped down, and the water inside splashed out with a loud 'splash'.

Then the thick end of the trunk rose high, paused for a moment, and then suddenly fell down.

The wooden stick embedded under the tree trunk hit the stone mortar, making a "clang" sound.

The principle of this thing is very simple. It is actually the seesaw that we often play on.

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

In this way, as long as water continues to be poured into it, this simple water mill will work tirelessly.

Of course, a real water mill is not like this. Instead, it relies on the flushing of water to drive the rotating shaft, and then the object on the rotating shaft drives the wooden pole to pound the rice.

However, this water mill was too complicated. Han Cheng and Bo fiddled with it for a few days and felt that it could not be completed in a short time.

After some thought, Han Cheng came up with this extremely simple water mill in a different way.

Of course, this kind of water mill is just a transition, and attempts to create a more complex version of the water mill must continue.

Because this simple version of the water pestle can only be used to pound rice or other things, while the complex version, with a slight change on the basis of the water pestle, can be used to drive the stone mill, Han Cheng naturally would not give up.

The people of the Qingque tribe who were standing on the side stared with their eyes wide open as they watched the water mill being raised and lowered from time to time by the continuous injection of water.

Is this how the tool is used?

Ordinary water has such a function?

After the surprise, a feeling of sudden enlightenment arose in my heart.

Water can indeed be used in this way, but they couldn't think of this method until the Son of God had completely fixed things.

"Try to get some millet."

Han Cheng looked at the people around him who seemed dazed and surprised, and said.

Because when I came I said that I was here to experiment with the water mill, so I brought millet with me.

After hearing Han Cheng's voice, Zhuang, who often pounded rice, hurriedly brought over a jar.

While the water mill was slowly rising, he poured three bowls of millet into the mortar.

Then everyone stood together and waited to see the result.

The water flowed, filling the trough, and the water mill rose and fell, crashing into the stone mortar.

This really does not require any effort on the part of the user, all that is required is some post-cleaning work, which is indeed very easy.

A few strong men who often pounded rice felt unusually happy when they saw the husked millet being pounded into the stone mortar.

But this happiness did not last long, because they discovered a problem.

The problem was that the speed of the water-based pestle was too slow. They pounded the rice at the normal speed for five times in a row, but the pestle could not pound once.

It does save effort, but isn’t the speed really too touching?

If you use such a water-based millet to pound rice, at the end of the day, can the pounded rice be enough for the people in the tribe to eat in one meal?

this……

More and more people became aware of this problem, and the people of the Qingque tribe, who had been happy for a short while, soon became silent.

The witch's brows were a little furrowed. This water-mill was indeed exquisite, but the speed of pounding rice was indeed a bit too slow.

As he was thinking this in his mind, after a while, Wu's brows suddenly relaxed.

Because he remembered what Mu Tou had been doing these days.

More than one piece of stone and wood was needed to carve the mortar.

In other words, the Son of God wanted to install more than just this one water mill.

A water-powered pestle is certainly not as fast as a human, but if you install three, four or more of them, wouldn't the speed of pounding rice increase?

Moreover, this water pestle relies on the power of water flow. It is tireless and its speed never slows down. It is different from a person who pounded rice who would get tired after a while.

If you calculate it this way, this water mill is very useful!

Thinking this in his mind, Wu looked around. The terrain here was open, so it would be no problem to install three or four water mills.

It has to be said that Wu, the former wisest man of the Qingque tribe, is not just a reputation for nothing.

When many people were still confused, he had already figured out what was going on.

The witch figured out the whole thing, and the more he thought about it, the happier and more excited he became.

Seeing everyone still looking confused, he lowered his voice and prepared to explain the matter to them.

"I have something to say, please listen carefully!"

This was certainly not said by Wu, but was made up by Han Cheng, who was standing nearby, after noticing Wu's actions.

Wu does not have the aura of Prime Minister Zhuge Liang, so the people of the Qingque tribe will naturally not have a heart attack due to his exuberant verbal attacks.

But the effect is still there.

After Wu said this, everyone felt as if they suddenly understood everything. Some people even reacted as violently as Zhuang, picking up their own hands and slapping them on their heads.

Yes, one water pestle cannot pound rice as fast as a person, so wouldn’t it be better to set up a few more?

I couldn't figure out such a simple thing.

There were still many things they couldn't figure out. When Han Dashenzi asked Bo to make a bamboo pole and tie it to the other side of the three upright pillars, Zhuang's speed of slapping his head became faster, like a water mill.

Two bamboo poles were used to pour water into the water trough of the water mill at the same time, and the time between the rising and falling of the water mill was shortened by half.

In other words, at the current frequency, three water pestles can exceed the normal speed of one person pounding rice.

Moreover, the wooden stick used to pound rice under the water pestle is thicker, and the stone mortar underneath is also larger than the one used to pound rice manually, so more millet can be pounded out at one time.

As everyone waited, the husks of the millet in the stone mortar were gradually broken.

Seeing this, Zhuang and Qinghua, who had a red spot on their foreheads, were about to go over to take out the pounded millet in the mortar and clean it up, but were stopped by Han Cheng.

After adding another bamboo tube, the speed of the water mill became faster, and the time interval was not enough for people to get the millet out.

If you operate in this way, you may easily get injured by the water pestle.

Han Cheng found a wooden pillar that he had asked someone to bring before, and when the water mill was raised, he placed it near the horizontal bar to support the tree trunk. In this way, the water mill would not fall down. Zhuang and Qingcao could boldly take out the millet from the mortar and clean it up without being too panicked.

After the stone mortar was filled with grain again, the wooden pole underneath was laid down, and the water mill continued to work tirelessly...
