I am a Primitive Man

Wow~

when!

The water in the bamboo tube is flowing continuously, and more and more water is stored in the tank behind the trunk.

With the continuous injection of water, this side is getting heavier and heavier, and the part that was originally raised began to slowly fall down.

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

When the water in the tank became more, the trunk finally lost its balance completely.

The side of the sink suddenly fell down, and the water in it also splashed out with a 'splash'.

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

The wooden stick inlaid under the trunk hit the stone mortar, making 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 by water and thick wood itself.

If this continues, as long as water is continuously poured into it, this simple water pestle will work tirelessly.

Of course, the water pestle in the true sense is not like this, but relies on the washing of water to drive the rotating shaft, and then the things on the rotating shaft drive the wooden pole to pound rice.

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

After thinking about it for a while, Han Cheng came up with this extremely simple water reed in another way.

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

Because this simple version of the water pestle can only be used to pound rice or smash some other things, while the complex version can be used to drive the stone mill with a little change on the basis of the water pestle. Naturally, Han Cheng Never give up.

All the members of the Qingque tribe surrounded by the water flow continuously poured in, and their eyes widened when they saw the water pestle that was rising and falling from time to time.

This tool is actually used in this way?

Ordinary water, still has such a function?

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

Water can indeed be used in this way, but they couldn't think of such a way before the son of God got everything done.

Try to get some millet,

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

Because I said it when I came here, I came to test the water reel I made, so I brought millet with me.

At this time, after hearing Han Cheng's voice, he often pounded rice, so he quickly brought a jar over.

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

Then everyone stood together and waited to see the result.

The water flows and fills the trough, and the trough rises and falls, and falls into the mortar.

It really doesn't require human effort, it only needs to do the post-cleaning work, which is really very light and easy.

A few people who often pound rice are very happy when they see the shelled millet smashed in the stone mortar.

But that joy didn't last long.

Because they found a problem.

That is, the speed of this water pestle is really too slow. They pounded rice at normal speed, even if they pounded rice five times in a row, the water pestle could not even beat it.

Saving effort is saving effort, but this speed is really touching, right?

Using such a water pestle to pound rice, after a day, can the millet that comes from the pounding be eaten by the people of the tribe?

This……

More and more people are aware of this problem, and the people in the Qingque tribe, who were not happy for a long time, soon became a little silent.

Wu's brows were also tightly furrowed. This water pestle was indeed delicate, but it was indeed a little too slow in terms of the speed of pounding rice.

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

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

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

In other words, this is not the only water pestle that the Son of God wants to install.

Although the speed of a water pestle is not as fast as that of a human, if three or four or more are installed, the speed of pounding rice will increase?

Moreover, this water pestle relies on the power of the water flow, and it is tireless at all, and its speed will never slow down, which is different from people who get tired after pounding rice for a while.

In this way, this water pestle is very useful!

Thinking of this in his heart, Wu looked around. The terrain here is open, and it would not be a problem to install three or four water reels.

It has to be said that Wu, the original number one wise man of the Qingque tribe, did not get his name for nothing.

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

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

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

I have a word, please listen carefully!

Of course, this was not what Wu said, but Han Cheng, who was standing aside, noticed Wu's actions and made it up in his own brain.

Wu didn't have the momentum of Prime Minister Zhuge, and the people of the Qingque tribe naturally wouldn't have a heart attack caused by his hearty talk.

But the effect is still there.

After Wu's words were spoken, everyone suddenly understood, and even those who reacted fiercely picked up their own slaps and slapped them directly on the head.

That's right, a water pestle can't compare to the speed of a person pounding rice, wouldn't it be enough to set up a few more?

Such a simple thing, I can't figure it out.

There are still many things that they can't figure out. After Han Dashenzi let another bamboo pole get through and tied to the other side of the three vertical pillars, Zhuang's head-slapping speed became faster, just like a water peg. .

The two bamboo poles poured water into the water tank of the water pestle at the same time, and the time between the water pestle falling together and falling was directly shortened by half.

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

Moreover, the wooden sticks used for pounding rice under the water pestle are thicker, and the stone mortar below is also larger than the stone mortar used for pounding rice by hand, so that more millet can be pounded out at one time.

While everyone was waiting, the millet in the stone mortar was gradually smashed out of its shell.

Seeing this, the red Zhuang and the blue and white flowers on their foreheads were about to go and clean up the pounded millet in the mortar, but they were stopped by Han Cheng.

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

If you do this, it is easy to be injured by the water pestle.

Han Cheng found a wooden pillar that he ordered someone to bring here before, and when the water reel was raised, he stood it near the horizontal bar to support the tree trunk. Feel free to take out the millet in the mortar and clean it up without getting too flustered.

After refilling the millet in the stone mortar, and then lowering the standing wood below, the water reel continued to work tirelessly...
