The water rushed down the canal, and at first it was a stream of turbid muddy water. It hit the water wheel, and the shaft began to rotate creakingly, and the stone mill mounted on the shaft also started to rotate.

"Move, move!"

Everyone's eyes were fixed on the stone mill, and when they saw this situation, there was a commotion of excitement.

"Put the wheat on it and try it."

Feng Yong was equally delighted and quickly ordered.

The wheat that had been prepared long ago was poured into the hole of the stone mill. After a while, the slightly gray flour began to overflow.

"well!"

Feng Yonggang screamed, but unexpectedly the stone mill gradually turned slower and slower, and finally stopped moving after making a few "geek" sounds.

"what happened?"

When Niu Wa saw it, she became anxious and looked down.

"Do you want to die?"

Feng Yong was startled, pulled him back, and shouted sternly, "What did I tell you at the beginning? I told you to pay attention to your safety. If you stick your head in like this, how many of your heads will be twisted?"

"Master's house..."

Niu Wa shrank her neck after being scolded, then looked down unwillingly, snarled, and did not dare to say any more.

The stone mill next to it seemed to be responding to Feng Yong's words, and suddenly began to move "rattling" again.

The corner of Feng Yong's mouth twitched. Isn't this crazy?

Unexpectedly, it only turned around twice and stopped again.

Damn it!

Feng Yong was so angry that he kicked him twice.

Niu Wa scratched his head and walked around the stone mill, sweating profusely. He really didn't expect that after two months of hard work, the thing he made with so much care was so disappointing.

Unfortunately, this thing didn't exist before, and I don't even know what the problem is.

Feng Yong frowned, pondered for a moment, patted the millstone, and said, "Go and ask the superiors to enlarge the water more."

Someone in the crowd immediately ran out.

After a while, a louder sound of water flow came, and the millstone began to rotate again.

"Moved……"

Niu Wa said excitedly, and glanced at Feng Yong with admiration: "I couldn't see the problem with something I made with my own hands, so why could the owner see its faults at a glance?"

Feng Yong looked calm, but he didn't care about the admiration of everyone, "Put the wheat on."

At the same time, I feel a little disdainful. There are three major structures: power structure, transmission structure, and working structure. The working structure is a millstone. What can go wrong with these two stones?

The transmission structure is a straight round wood, so there will be no problems.

The only problem is the power structure.

There is a problem with the power structure, either because there is insufficient power or there is something wrong with the equipment itself.

If there is no way to determine the equipment problem at the moment, then check the power and energy problems first.

Fortunately, this is not an equipment problem, but insufficient water power.

A bag of wheat was ground quickly, more than ten times faster than human power.

The millstone is still rotating with no sign of stopping, which seems normal.

Feng Yong picked up the flour and looked at it. In fact, the flour ground by the stone mill was not fine enough, but why should we eat it so finely in this era?

Not having to eat anti-human food like wheat rice is a huge improvement.

He clapped his hands, then smiled and said, "It's done."

Everyone, who had been watching carefully and holding their breath for fear of further problems, cheered again.

"Everyone has worked hard these days. This water mill has been made, and everyone has contributed. Tonight I asked the canteen to add more food for everyone, and give everyone a reward. The meat cakes are enough."

Then the cheers became even louder.

Feng Yong turned his head and said to Niu Wa, "In the past two days, you continue to test this water mill. See how much water should be put into the canal."

If the grinding disc rotates too fast, the grinding will not be fine enough.

The rotation is too slow and the efficiency is not high.

"Find out the most suitable water flow, write it down when the time comes, and follow this approach in the future."

After working for a long time, seeing that lunch time was almost over, Feng Yong ordered, "Hang up this millstone and put it away. You have something to eat first, and Niuwa stays."

In Yuexi, for the Yi people, it is difficult to guarantee two meals a day. It is normal to be hungry and full.

Feng Yong's arrival allowed them to eat twice a day and be full, which made them extremely grateful.

Nanxiang is the only place where eating three meals a day has become the norm.

For these craftsmen, their lunch is actually steamed buns and hot soup, and at most they order pickles to eat with them. This is the best treatment they can enjoy in Yuexi, which makes others envious.

After everyone had gone out, Feng Yong took out a notebook and Tan Xiao, sighed and said, "You tell me, I'll write and tell me in detail how to build this water mill and how to install it."

Niu Wa smiled sheepishly, came over and started to explain to Feng Yong.

Although basic education is promoted in Nanxiang, there are still too few talents available.

It is already rare to have a team of people to handle various matters for you.

As for analyzing information, summarizing it in writing, and making decisions, you still have to rely on yourself.

Just like the simplest water mill now, Feng Yong still needs to do it himself, draw parts diagrams, write down the production process, etc.

"If you could study with more care, I wouldn't have to do such a small thing myself."

Feng Yong took a charcoal pencil and drew a water-milled perspective drawing along the ruler made of wood chips while chattering.

Niu Wa didn't say anything. He stared straight at what his master had drawn without blinking. He felt that the pen in his master's hand was really magical.

The structure of the water mill is clear at a glance, plus the various parts and installation procedures are drawn next to it. As long as someone can get these pages, they can make a water mill according to the pictures above.

After all, he personally tinkered and improved the water turbine, the main component of the water mill, so Feng Yong still knew the water mill very well. He started writing and drawing and completed it quickly.

Although the perspective drawing is not standard, it can barely be seen.

Once again, I would like to thank "Linear Algebra", "Cartography", "Analytical Geometry" and other university subjects. They have made many people almost go crazy learning them in the past.

Although Feng Yong didn't go crazy, it was still difficult, and he always felt that it was useless to learn. Now he finally knows that he was wrong.

Damn it, you all look down on handicrafts, but I am going to do the opposite. Not only do I want to write it down, I also want to print it out.

I picked it up and looked at it carefully. I was about to check if there was anything missing, but unexpectedly the light suddenly dimmed.

"What are you doing? Get out of the way. Didn't you see that I was writing something?"

Feng Yong thought it was Niu Wa coming over to take a look, so he pushed impatiently.

"The prince is so elegant that he can study in a place like this."

Feng Yong was shocked, why didn't this voice belong to Niu Wa?

Turning around, he saw a handsome middle-aged man standing in front of him, looking at him with a smile.

"Oh! When did Jiang Canjun come? You were so rude just now."

Jiang Wan's appearance here was really surprising, and Feng Yong quickly said hello.

"I just arrived in Yuexun, but I didn't see the prince. I heard someone said that Yuexun is newly settled and busy with everything, so the prince has no time, so I thought of coming over to take a look."

Jiang Wan looked at the mill, and his eyes were drawn to the millstone that was still spinning. He was a little surprised and walked over, tentatively reaching out and touching it to make sure that his eyes were not blurry.

He circled the millstone twice, and finally raised his head in disbelief and looked at Feng Yong in horror, "Is this a millstone made by a prince?"

"It's a millstone, but it wasn't made by me. It was made by my subordinates. I just came up with an idea. In fact, it is mainly due to me as a banker."

Feng Yong pointed at Niu Wa.

Jiang Wan glanced at Niu Wa, nodded slightly, and then looked at Feng Yong, "Why do you need to be humble? You are good at making camp utensils, and Wan has seen this in Nanxiang."

As he spoke, he stretched his neck desperately and looked along the axis, as if he wanted to see clearly what was below, making people worry that he would accidentally fall.

Fortunately, Jiang Wan's safety awareness was higher than that of Niu Wa, so he didn't intend to stick his head inside. He only heard him praise, "The Book of Changes says: the same goal leads to different paths, and the same goal leads to hundreds of worries. I have seen it today.

.Is this millstone similar to that water mill?"

"It's really similar."

"Can you tell me how Wan Yiguan works?"

Jiang Wan looked at Feng Yong longingly like a child seeing his beloved toy.

"What's so difficult about this? Just put down the millstone on the hanger. Come on, put down the millstone above."

Feng Yong directed Niu Wa, and then poured the wheat himself.

Seeing the flour continuously overflowing, Jiang Wan's face was full of joy, "With this thing, you won't have to work hard to grind wheat in the future. Lord, I wonder what this thing is called?"
