In a place with relatively steep terrain outside Qiongdu City, a new canal was diverted from the Sunshui River, and a mill was built below the canal where the flow of water was the fastest.

For the past two months, Niu Wa has been leading people in this mill to build equipment according to Feng Yong's wishes.

It wasn't until today that everything was built and ready to be installed.

When Feng Yong arrived, Niu Wa hurriedly greeted him, "Master, everything is ready."

Feng Yong nodded and asked, "Are you sure?"

"Yes. This one is almost the same as the water bucket, that is, the stone bucket is replaced by a stone mill. It's very simple."

The water bucket is a tool that uses water power to shell grains. It appeared no later than the Western Han Dynasty.

This is because in the book "New Theory" written by Huan Tan of the Western Han Dynasty, it was mentioned: ... and the mechanical use of donkeys, mules, oxen and horses, and water-pounding was restored, and the benefits were a hundred times greater.

Among them, "throwing water into the rice and pounding it" means pounding the rice by using the water wheel to drive the rice mill.

With the promotion of new farming tools and advanced farming techniques in recent years, Dahan's food harvest has always been considered bumper compared to previous years.

Coupled with the emergence of delicious food such as steamed buns and dry food, the demand for flour among the Han Dynasty increased.

In other words, the Xinghan Hui had a lot of livestock on hand, and could use cattle, horses and other livestock to grind mills. This barely ensured the supply of flour to the imperial court and Yuexi.

If we really have to use human power like other people do, I don't know how much manpower and time it will take, and the efficiency is really appallingly low.

After having an urgent need, Feng Yong finally turned his mind to water power: Damn it, if I can't make a water-powered textile machine, can't I make a water mill?

The cows and horses also need to eat fodder and rest at night. The water mill runs day and night, so the efficiency is lost.

Start it!

Although Niu Wa is a bit stupid at studying, she finally inherited the fine tradition of Ding Er's family who is not good at studying but has strong motivation and ability.

In addition, after all, I had stayed in a school, and followed Feng Yong around the world, my horizons finally broadened.

After listening to Feng Yong's idea, I could quickly understand what Feng Yong meant and said that this matter was very simple.

This matter is of course simple.

Because the clever working people of ancient China had helped solve the most difficult part of the water mill hundreds of years ago: the water turbine and the rotating shaft.

Originally, Feng Yong thought about adding some gears or covering it with an iron sheet to extend its lifespan, but after carefully observing the physical form of the Shui Lei, he gave up the treatment.

Although in the eyes of Feng Yong, who was used to large-scale industrial manufacturing in later generations, the hydraulic turbine and rotating shaft made of pure wood were primitive, rough, and typical of being stupid and thick.

But I can’t stand the fact that the structure is simple. The simple structure means that the maintenance is also simple, not to mention that this thing is much stronger than imagined.

The only drawback is that the efficiency is a bit low, but in this era, compared to human and animal power, it is highly efficient.

Feng Yong fiddled with it for a long time before he discovered that the only modification he could make was to make its blades shrink in shape based on physical principles and the appearance of later generations of water turbines, which could maximize the hydraulic conversion efficiency.

As early as the Western Han Dynasty, water hammers had been widely used. All Niu Wa had to do was to replace the rice pounding tool with a millstone for grinding flour.

At the age of eleven or twelve, Niuwa could make a curved plow that he had never seen before according to the drawings of his father. This technical problem would definitely not be a problem for him.

"When installing later, pay attention to safety and don't hurt your hands or feet. The millstone on the hanger must be installed last to avoid falling and hitting people below."

Feng Yong saw that everything was ready and gave instructions.

The millstone is divided into upper and lower parts. The lower millstone must be installed on the rotating shaft, and the upper millstone must be hung up with a hanger. In fact, the principle is the same as the millstone at home when I was a child.

It's just replacing manpower with water power.

"clear."

"Okay, let's get started."

Standing in the room wouldn't help, it would get in the way, and it would also make the craftsmen timid. After Feng Yong told them to start, he turned around and walked out, finding a shade to sit down and wait.

First there were shouts in the room, then there was the creaking of wood, and then Niuwa shouted, "Be careful, nail it with force..."

Feng Yong looked at the water mill in front of him, his mind wandering a little.

The water mill is used for shelling, and the water mill is used for grinding powder. There is a similar structure to the water mill and water mill, and there is another thing called water drainage.

In fact, that is what Feng Yong wants most, because water drainage is actually hydraulic blasting to smelt iron.

The reason why Feng Yong wanted to tinker with this water mill was actually because he was stimulated by Huang Yueying.

After returning to Jincheng from Nanzhong, Feng Yong went to see Huang Yueying's improved blower, tried it himself, and then expressed his admiration for the national treasure engineer.

Unexpectedly, Huang Yueying's face was dull, and she said that someone in the later Han Dynasty had made a water drain that used water power to blow iron to smelt iron, but it was a pity that she didn't know how. Otherwise, if the blower and the water drain could be combined, then the big man would really not have to worry about the lack of iron.

Ironclad.

Feng Yong was shocked at the time. He didn't believe Huang Yueying's words at all and felt that she was just bragging.

What the hell, I graduated from a prestigious university, and I invented a blower that still leaked air. You actually told me that two hundred years ago, someone made a hydraulic blast iron smelting equipment?

Later, Huang Yueying handed over a copy of "Dongguan Han Ji", which indeed recorded the story of Du Shi when he was the prefect of Nanyang, in order to save people's labor, he made water pipes to smelt iron.

Feng Tibi's face was beaten so hard that it became red and swollen.

It's a pity that there are only a few sentences in the book, and the specific structure of the water drainage system is not mentioned at all!

The reason why this water drainage can be recorded in the book is to praise Du Shi for his dedicated service to the people when he was an official. It is fortunate that it has been known to others.

What the hell!

Feng Yong was so angry that he almost yelled, "Why don't you remember such an important thing just because it is a craft job and related to a lowly industry?"

Feng Turtle felt like he had married a husky!

Nowadays, if you want to find the structural diagram of the water drainage system or find Du Shi's descendants, they may have something written down by their ancestors. But after so many years, who knows who Du Shi's descendants are?

The second way is to go to Nanyang to find someone who can make drainage pipes.

Because Du Shi vigorously promoted water drainage in Nanyang back then, he left a lot of water drainage there.

But the world has been in chaos for decades, and many things have been lost. It is still unknown how many people in Nanyang know how to make water rows.

Huang Yueying came from a wealthy family in Jingzhou, so she had heard about this before. She just knew that Shuipai and Shuidi were similar, and she really wanted to try to make it, but it would not happen overnight.

What's more important is that Huang Yueying needs to take care of her baby now and can't put too much thought into it, so the restoration work of the drainage system was simply stopped later.

Without the technical support of professionals, Feng Yong had no choice but to retreat to a simpler solution: water mill.

Practice your skills first and accumulate some experience. Maybe with more experience, you can figure out how to drain water?

I don't know how long it took, but I saw Niuwa running out from inside, with a happy face, "The master's house is safe now."

"Oh?" Feng Yong stood up and patted his butt, "Has the water in the canal been drained?"

"I've already asked people to go ahead and put it away."

"Okay, let's go take a look inside."

Walking into the mill, you can see that the millstone on the hanger and the millstone on the rotating shaft have been meshed together. It is only waiting for the water from the canal to rush over, drive the water turbine, and then drive the millstone to rotate through the rotating shaft.
