Many tribesmen watched as the miniature waterwheel turned in the water, transporting water up and then flowing along the aqueduct into Meng Yuqing's home.
"You want to build a small waterwheel in the city, right?" asked a tribesman.
"Yes, but the function of the waterwheel to transport water in the city is only incidental. The main function is to use the force of the waterwheel's rotation to help us do some things." Meng Yuqing raised his chin towards Xuan, and Xuan instantly understood what he meant.
Walk directly to the waterwheel and remove the Y-shaped wooden stick supporting the wooden pestle.
Under the action of gravity, the end tied to the stone hammer was hammered directly into the stone trough, while the tail of the wooden pestle was raised high.
As the waterwheel turned, the lever on the bearing shaft pressed down the raised tail of the wooden pestle, and the end of the stone hammer was lifted up.
After the lever turned, the pressure on the tail of the wooden pestle was gone, and the end of the stone hammer fell down again.
After the demonstration, Meng Yuqing said to them, "This is it. We need to build this in places with fast-flowing water in our city. Then we won't need people to hammer the shells manually."
"In addition to combining the waterwheel and mortar, we can also use gears to combine it with a stone mill. After we have mastered this, we can use the rotating force of the waterwheel to do many things."
After listening to Meng Yuqing's words, the eyes of many tribesmen lit up. They had been worried that the planting area had expanded so much this year, and they would not be able to handle the threshing, shelling and grinding of the crops.
Now we just need to make these machines and then we can let them help us do the work when the time comes.
The water is always flowing, which means the machine can work non-stop.
So everyone was ready to go, thinking that they must make more.
The crowd went to the timber storage area to move the timber. On the way, Meng Yuqing asked Xuan, "Is the ironworks still busy?"
Hearing Meng Yuqing's question, everyone, including Xuan, froze and looked at Meng Yuqing.
Meng Yuqing noticed that there was fear in their eyes, as if they were afraid that he would suddenly come up with another idea.
It’s not that they don’t want to work, but there really is no manpower left.
Meng Yuqing touched his nose and said awkwardly, "I'm just asking, don't be nervous."
Hearing him say this, everyone breathed a sigh of relief. After a while, Xuan couldn't help but ask, "Have you thought of something else?"
"I suddenly remembered that I could make a faucet," said Meng Yuqing.
"Faucet?" Xuan looked at him puzzledly.
"It's something that turns the water on and off." Meng Yuqing gestured with his hands. "I thought it was complicated at first, but after some research, I found the principle is quite simple."
"That thing needs to be made of iron, right?" Xuan continued to ask.
"Yes, it can actually be made of wood, but it will easily wear out if it is opened and closed frequently. It would be too troublesome if it needs to be repaired every few days." Meng Yuqing looked up at the tribesmen and found that they did not have any strange expressions, so he continued.
"If we want every household to have running water, then when we build the waterwheel in the city, we can build a smaller reservoir next to it, connect pipes from the bottom of the waterwheel to the courtyard, and install a faucet at the water outlet."
After listening to this, Xuan thought for a moment and said, "Let's get the small reservoir next to the water truck ready first and connect the pipes. We'll deal with it later."
He looked at Meng Yuqing and gave a helpless smile, "We don't have enough manpower right now."
Meng Yuqing nodded and said, "Yes, let's make the waterwheel and other machines that require water power first."
After selecting the right wood, everyone moved it to the processing area.
The large waterwheel with a diameter of more than ten meters has been made, and the small waterwheel with a diameter of three meters is relatively easy to make.
On the other side, Bei Jie was taken away by the person in charge of the river embankment construction team. When the person in charge of the river embankment team took Jie to the water source where they were currently constructing, Jie was still a little confused.
He thought he was a relatively smart person, otherwise his brother, the clan leader, would not have entrusted so many important matters to him.
But since arriving in Qingshan City, he has felt like a fool.
"Is all I have to do is work with you to build this kind of wall along the water?" asked Jie.
He could understand digging holes to drain water and building reservoirs, but he didn't quite understand enclosing this kind of wild water source.
The head of the riverbank team nodded and said, "Yes, didn't it rain for a long time last year? All the water flowed out, so this year the witch asked us to raise the banks near the water source."
After this explanation, Jie finally understood. There was a big lake in their tribe. After the heavy rain last year, the water in the lake overflowed.
The water in the homes of those tribesmen who lived closer to the lake was above 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 the water overnight, and all the sub-beasts whose homes were flooded were moved to the homes of those tribesmen whose homes were not flooded to stay temporarily.
Even so, several sub-beasts still fell ill.
Fortunately, they had a good relationship with Qingshan City, and they exchanged a lot of herbs for treating coughs and fevers, and rescued the sick tribesmen.
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 that after he returned, he would talk to his brother and ask them to raise the area around the lake a little bit.
Even if you can't block all the water, you can at least let less of it out.
In the dam group, Jie was working hard to move bricks, soil and mud, while Zhuo from the Black Tree Tribe was taken to the place where a large waterwheel was being made.
