Many clansmen watched the miniature waterwheel whirling in the water, brought the water up, and then flowed along the aqueduct all the way to Meng Yuqing's house.

"Is it just to build a small waterwheel in the city?" a clansman asked.

"Yes, it's just that the function of the water truck in the city is only incidental. The main function is to use the power of the water truck to help us do something." Meng Yuqing raised her chin towards Xuan, and Xuan immediately understood what he was. mean.

Go directly to the waterwheel and remove the Y-shaped wooden stick supporting the wooden pestle.

Under the action of gravity, the end with the stone hammer directly hammered into the stone groove, while the tail of the wooden pestle was raised high.

As the waterwheel rotates, the lever on the bearing shaft presses down the raised tail of the wooden pestle, and the end of the stone hammer is lifted up.

After the lever was turned away, there was no pressure on the tail of the wooden pestle, and the end of the stone hammer came down again.

After the demonstration was completed, Meng Yuqing said to them, "This is the thing. We will build this in places with strong water flow in the city. When the time comes, people won't need to manually hammer it out of the shell."

"In addition to combining the waterwheel with the mortar, the gears can also be combined with the stone mill. Anyway, after many things are done, we can use the force of the waterwheel to do many things."

After hearing Meng Yuqing's words, the eyes of many clansmen brightened. They were worried that the planting area had expanded so much this year, and when the time came, threshing, hulling, and flour milling would be busy.

Now as long as these machines are made, the machines can help them do it when the time comes.

The water is always flowing, which means that the machine can work continuously.

So everyone geared up, thinking that they must make more.

The crowd went to the place where the wood was stored to move the wood. On the way, Meng Yuqing asked, "Is the ironworks still busy?"

Hearing Meng Yuqing's question, everyone including Xuan froze, and then looked at Meng Yuqing.

Meng Yuqing noticed that there was a little panic in their eyes.I was afraid that he would suddenly come up with an idea again.

It's not that they don't want to work, but that there are really no people left.

Meng Yuqing rubbed her nose and said awkwardly, "That's all I'm asking, don't be nervous."

Hearing what he said, everyone breathed a sigh of relief. After a while, Xuan couldn't help asking, "Did you think of something again?"

"Suddenly it occurred to me that I can make a faucet." Meng Yuqing said.

"Faucet?" Xuan looked at him suspiciously.

"It's something that can turn on and off the water." Meng Yuqing gestured with her hand, "I thought it was complicated before, but after researching it, I found that the principle is not difficult."

"Is that thing made of iron?" Xuan continued to ask.

"Yes, it can be made of practical wood, but it is easy to wear and tear if it is switched on and off frequently. If it needs to be repaired every three days, it will be too troublesome." Meng Yuqing looked up at the people of the clan, and found that they had no strange expressions, and continued Go on.

"If we want every household to have running water, then when we build the water tanker in the city, we can build a smaller reservoir next to it, and then connect the pipeline to the yard at the bottom of the tanker, and then the water outlet Install a faucet."

After listening to Xuan, he thought for a while and said, "Fix the small reservoir next to the waterwheel first, and connect the pipes later."

He looked at Meng Yuqing with a helpless smile, "There are not enough people now."

Meng Yuqing nodded and said, "Yeah, let's make the waterwheel and the machines that need water power first."

After selecting the suitable wood, everyone moved the wood to the processing area.

The large waterwheels with a diameter of more than ten meters have already been made, and the small waterwheels with a diameter of three meters are quite easy to make.

On the other hand, Jie was sent away by the person in charge of the embankment construction team. When the person in charge of the embankment team brought Jie to the water source they were currently constructing, Jie was still a little confused.

He thought he was a smarter type of person, otherwise his patriarch brother would not have entrusted him with many important things.

But ever since he came to Qingshan City, he felt like a fool.

"What I want to do is to build this kind of wall around these waters with you?" Jie asked.

He can understand digging pits to divert water and build reservoirs, but he doesn't quite understand how to enclose such wild water sources.

The person in charge of the embankment team nodded and said, "Yes, didn't it rain for a long time last year? The water all flowed out, so this year Wu asked us to raise the banks near the water source."

After such an explanation, Jie also figured it out. There is a big lake in their tribe. After the heavy rain last year, the water in the lake overflowed.

The homes of those clansmen who lived near the lake were flooded up to their ankles.

It would be fine if it was summer, but it was already autumn, and the sub-beasts would definitely get sick if they were soaked in water like this.

So the orcs dug pits to drain water overnight, and all the sub-beasts whose homes were flooded were first moved to the homes of those who were not flooded.

Even so, several sub-beasts were still sick.

Fortunately, they have a good relationship with Qingshan City. They bought a lot of herbal medicine for cough and fever, and rescued those sick clansmen.

He remembered that it took them a long time to control the water. Looking at the people who were busy building the wall, he thought, after returning, he would also talk to his brother about raising the height of the lake.

Even if you can't block all the water, you can make less water come out.

In the embankment group, Jie worked hard to move bricks and earth and mud here, while Zhuo from the Black Tree Tribe on the other side was dragged to the place where he made a large waterwheel.

He directly turned into a big tree and used the branches and roots to pass things up to the humanoid orcs working on it.

With his transportation, the construction speed of this large waterwheel is obviously much faster.

When eating lunch, he turned into a human form and walked towards a completed waterwheel while eating food.

Then he walked all the way to the paddy field area in the planting area along the water transported by the big water truck. He looked at the neatly arranged paddy fields and sighed in his heart.

As a tree orc, he has never felt hungry since he was a child. They can deliver nutrients to wild vegetables, and the sub-beasts in their tribe have never been short of food.

They don't need to go after wild beasts specially, as long as they stay there quietly, some wild beasts will come to their door and they will be easily caught by them, and their demand for beast meat is not as high as other orcs.

But in the great forest where their Black Tree tribe was, there lived many other tribes.

He naturally knew how desperate those tribes were for one bite.

Even if you try your best, you may not be able to get that bite.

But he saw it in Qingshan City today, as long as the people here work hard, they can gain something.

Although sometimes there will be some bad weather in the mainland, causing some fragile plants to die, but he feels that with the presence of the witch in Qingshan City, he will definitely have a way to deal with it.

For example, those raised banks on the edge of the water source, various drainage channels, and pools for storing water.

At least that witch is already taking some measures regarding the matter of plants being flooded and dying of thirst due to lack of water.

He even saw that the people in Qingshan City would bring nutrients (fertilizer) from other places. As a tree orc, he certainly knew that the bones of dead beasts, fallen dead leaves, and the excrement of beasts would be slowly destroyed after a long time. Plants absorb and make plants better.
