Chapter 60
Qin Yao stayed at Carpenter Liu's house until two or three o'clock in the afternoon. After confirming all the details, he drew him a detailed scale drawing again, and then went home with a growling stomach.

The sun was just right at noon, and Liu Dafu's field was already burning wheat stalks after harvesting the wheat. The fields in the village, as far as one could see, were full of busy farmers.

The large piece of fertile land near the river in the east of the village is all owned by Liu Dafu's family. Every year when spring plowing comes, some villagers come to the door with chickens and ducks, wanting to rent his family's field for farming.

Qin Yao recalled Old Man Liu's suggestion that renting the good land from Liu Dafu's house should be cultivated as soon as possible.

But now, whenever she thinks of the exhaustion of working in the wheat fields a few days ago, all the cells in her body are screaming: Run!
Forget it, there are still some days before spring plowing, let's get the hydraulic stone mill out first and check the situation. If the situation is not good, it's not too late to go find Liu Dafu.

With an idea in mind, Qin Yao concentrated on working on her hydraulic stone mill.

She first sorted out a flat area by the bridge on the north bank of the river near her house.

Then I went to the lower reaches of the river and brought back two boulders weighing several hundred kilograms.

During the whole day, except for eating, drinking and sleeping, I used a pickaxe to tap on the stone for the rest of the time.

After five days of beating like this, two grinding discs with a diameter of [-] centimeters and a thickness of [-] centimeters were produced.

Then punch a hole in the center of the grinding disc, install the rotating shaft and wooden handle, and a large grinding machine is ready.

At the same time, news came from Carpenter Liu that all the waterwheel parts had been obtained, and someone was sent over to ask her to assemble them together to avoid making mistakes.

Qin Yao went there after breakfast, and together with Liu Carpenter, tossed in the yard of his house all day, putting together a waterwheel that was as tall as a person.

The bearing shaft was also finished, and the two of them couldn't wait to see the effect. After chewing a few mouthfuls of dinner, they carried the waterwheel and the bearing shaft to the river.

The villagers were at leisure after supper. They saw Qin Yao beating by the river these days, and they were wondering what she was doing.

Seeing her and Carpenter Liu carrying waterwheels and other things towards the bank of the river, they all followed curiously.

When Qin Yao and Qin Yao arrived at the river, all the leisure people in the village came.

The people from the Liu family's old house were also among them. Qin Yao didn't even need to say hello, and the brothers and sisters-in-law came over to help.

Mainly because he wanted to know what Qin Yao had done as soon as possible.

The adults dispersed the children who came over, and under Qin Yao's command, put the waterwheel into the river she had prepared. The base was filled with stones, and it started to rotate steadily in the water.

This is the first step, and the next step is to splice the stone mill and the bearings of each part.

No one else can intervene in this process, only Qin Yao and Liu Carpenter can operate it.

Fortunately, Qin Yao has great strength, otherwise she would not be able to lift these heavy wooden stakes by herself.

After assembling, Qin Yao shook to make sure it was stable, and personally lifted the boulder that she had placed by the river in advance, blocked the river with the big stone, stopped the water wheel, and put the other end of the stone mill on the wooden stake and Put the waterwheel together, and use wooden blocks to insert into the gap and knock tightly.

After the assembly was completed, the sky had already darkened, leaving only a smear of orange sun in the sky.

But not only did the number of villagers on the bridge not decrease, but there were even more of them than before.

The village chief and Liu Dafu were attracted by the excitement here. Liu Ji lit a torch from home and took it down, and there was light in the open space.

Qin Yao went down to the river, removed the blocked boulders, and quickly ran ashore.

"Wow!" All of a sudden, the river water poured into the narrow channel, forming a strong impact. The waterwheel turned, and the speed became faster and faster, vigorously driving the bearing shaft to rotate, and the force was transmitted to the handle above the millstone. Turn slowly.

"It's turning! It's really turning!" Carpenter Liu shouted excitedly.

Qin Yao quickly ran over to look at the millstone. Maybe it was because of the large flow of water at the moment, and the speed was quite fast.

"Really turned around?" The village chief came over curiously, and everyone made way for him.

Qin Yao nodded, also smiled, and asked Liu Ji to go home to take down the freshly sifted wheat.

Liu Ji was more excited than anyone else, and rushed home to get the wheat.

He saw with his own eyes that Qin Yao had been tinkering by the river for five or six days, and today she actually built such a big waterwheel and even made the millstone spin by itself. How miraculous this is!It was enough for him to brag for half a year.

"Come here, come here, Mai is here!"

Liu Ji rushed down with two buckets in his hands, one empty and one full of wheat.

He still knew to pick up an empty bucket.

Qin Yao took the wheat, put a handful into the hole in the middle of the stone mill, and immediately heard the crunching sound.

After a while, the ground wheat grains fell out. Qin Yao pushed them with her hands, and then they fell into the wooden trough next to the stone mill and automatically fell into the empty barrel along the slope.

The village chief couldn't wait for Qin Yao's slowness, so he personally scooped up a ladle of wheat and poured it into the mill.

The crumbs that have been ground for the first time fall out with a clatter, and after repeated grinding twice, they become fine flour.

Night has come, the torches by the river shine brightly, and people's surprised voices can be heard from time to time in the center.

"This grinding is faster than humans, and it's effortless. Madam Qin, how did you come up with this good guy?"

Qin Yao said that she had read it in a book and tested everyone's willingness to pay to use their own water mill.

Shopkeeper Liu jumped up from the crowd and asked: "Miss Qin, would you like to release this water mill for the convenience of the big guys?"

After asking, he was afraid that Qin Yao would think that he was using it in vain, so he immediately added: "I won't use yours in vain. If you tell me the rules, everyone will be happy to do it."

Liu Ji immediately tugged at Qin Yao's sleeves. For such a good product, we must charge more for its use.

Qin Yao didn't think about how to set the price for a while, but seeing that many people were eager to try, she responded loudly:

"It's too late today. Let's go to our own homes first. I haven't finished the water mill yet. After two days, I'll finish it. I'll come up with a rule and let everyone know."

The villagers thought about it and realized that the water mill was indeed very simple now. It didn't even have a shed. If it rained, the food would be damaged.

So Qin Yao told Qin Yao to remember to post a rule and tell the big guys that they were waiting to use her water mill.

Liu Dafu wanted to use it the most. His family had a lot of grain, and it would be exhausting to grind it by one person, so he specially invited five people to help grind the grain.

If Qin Yao's water mill can be used for this, it will save a lot of trouble.

You only need to send one person to watch here and pour the grain into the stone mill, and the people who were originally turning the mill can be freed up to do other things.

Someone asked Carpenter Liu to make one for his own home.

Carpenter Liu told him: "To make such a water mill, the wood processing cost is at least two taels of silver, not counting the two big millstones. These are all carved out by Mrs. Qin herself from the river to find big stones and bring them home. "

The villagers immediately dismissed the idea of ​​building a water mill at home.

What's wrong with having those two taels of silver, get a water mill?I'm afraid it's crazy!
