One day in late February, just after the food time, carriages drove north from Jiangling and Ying County. Their destination was the copper smelting workshop at the foot of Jishan.

The car stopped at the entrance of the workshop, and the bronze official Yang Xi immediately came up. Those who came today were his real immediate bosses, namely the workers, the workers' chiefs, and several respected craftsmen in Nanjun Worker Cao.

However, those working officials wearing official uniforms and crowns on their heads took the initiative to make way and let a very slow old ox cart drive in the front, but saw a father-in-law sitting in the car, sitting peacefully in the car. His robes were neatly arranged, but his hands were covered with calluses and wrinkles.

"I never thought that it was Weng Chen who arrived!"

Tong Guan Yangxi felt very surprised and hurriedly walked over and helped the old man down with a group of labourers and labourers.

The old man is Chen Yi, who is the oldest craftsman in Nanjun. When Chen Yi was young, he was an ordinary craftsman, but because of his outstanding skills and good at carpenters and stonework, he was transferred to Shu County to work under the command of Li Bing in Shu County. During those years, he and countless craftsmen helped Li Bing manage the Minjiang River and built the "Shenghuo" (Zeng Péng), which is the Dujiangyan in later generations!

That big weir was Chen Yi's lifelong pride. Under their wonderful ideas, the unruly Minjiang River changed from a great disaster to a great fortune in Shu County, irrigating thousands of miles of fertile land. Since then, the Chengdu Plain has been flooded and drought, and the people have not known hunger. The continuous supply of food along the river water to Nanjun, and then sent to the Central Plains to serve as the Qin army ration.

In Chen Yi's opinion, stool is already the limit of people's use of the power of flowing water. When Dayu controlled the flood, he summarized his experience: water can be loosened, but not blocked. He can only coax the water to the place where people want him to flow. As for controlling the water power like taming livestock and letting it help people work? It's simply arrogant!

So he leaned on a dove stick and said with a smile: "I heard that an Anlu craftsman wanted to make equipment that could be transported by himself without manpower. I have been a carpenter and stonework for decades. I have traveled all over Shu County, Ba County, and Nan County, and have been to Guanzhong, but I have never heard of such a magical tool. How can I not come and see it for a long time?"

Chen Yi's words made the workers and officials laugh. Like Chen Yi, they didn't believe that there was such a thing in this world, let alone a small craftsman from the county and township.

Indeed, they also heard that the little craftsman did make a pedal mortar, which has now been promoted in Guanzhong and Nanjun, and the other counties are gradually replacing human-powered mortars.

But in everyone's eyes, it was just luck, just a small instrument with simple structure. Did the craftsman think he was the reincarnation of Lu Ban?

A craftsman stroked his beard while walking in and said, "I once heard that the Gongshu squad made of wood to fly in the sky and fell down after flying for three days and three nights. The Anlu craftsman also claimed that this thing can move forever. It's really arrogant. I heard that it will be tried today. I want to see how it will end?"

Tongguan Yangxi was on the side and wanted to speak but stopped. He wanted to defend the honest and never rested at the construction site. However, he only saw that Jin had made a water wheel and made it run. It was unknown whether it could drive the wooden pestle, so he finally shut up and led everyone forward.

Their destination is a stream next to the storage site that is used to clean ore and wash away the soil. The water is two meters wide. Due to the terrain, it is relatively turbulent, and a group of people are busy around the stream.

"Who is citron?"

Chen Yi turned his head and asked Yang Xi, he could not tell who was the one who was a member of the ministers covered with mud and water.

"It's the person who is wrapped in a black cloth belt, holding a wooden hammer, and personally placing the equipment."

Chen Yi identified for a moment and finally found Jin, but saw that he, like the others, were wearing brown clothes and beating. He did not guide everyone on the shore, but ended up in person, and was currently flowing barefoot in the water.

Seeing this, Chen Yi's disgust against Jin was relieved a little. After looking at the equipment installed by the water, he couldn't help but be slightly surprised.

First, there is a wooden bracket more than meter tall, which is deeply nailed into the depths of the ground and is also tightly built with stones. The objects on the bracket look like a large thickened wheel, and it is like a wheel spinning used by a woman to weave cloth, which is enlarged many times. After standing up, one person is tall.

The wheel was equipped with several leaf blades. When the wheel was successfully placed on the water, everyone around the water moved away.

Next, an amazing scene appeared in Chen Yi's eyes: there was no human power to trample, nor did the livestock turn around. The huge machine seemed to have life. It began to rotate clockwise under the erosion of the stream and made a rustling sound, the speed was getting faster and faster, and finally the same speed as the flowing water.

After everyone moved aside, the other side of the water wheel was undoubtedly revealed: it was a rotating shaft driven by a gear, connected to the water wheel, and there were four staggered plates on the shaft, which also drove the rotating plates to rotate. Whenever the rotating plate was fiddled downwards with the tip of the pedal rod, it was like a person stomping downwards. The four pedal pestles placed under the rotating shaft moved themselves, and they all fell to the ground to pound the ore in the stone mortar!

"It's done!"

Ci and the bronze craftsmen who followed him to make wood and make wheels and tried for several days cheered.

Chen Yi and the craftsmen who saw this scene on the other side were stunned, as if the wooden pestle driven by a water wheel was smashed down, hitting not the ore, but their hearts!

They believe that humans cannot control the old idea of ​​using water to work, and are shattered by the facts seen with their own eyes!

"How come we never thought that we could use the power of flowing water in this way!?"

Chen Yi felt quite guilty. As an old craftsman for decades, he had never thought about this.

In addition to shock, Yang Xi had already brought Jin. Jin was an honest man, no better than his thoughtful wife. When he saw a group of county craftsmen, workers, and a white-haired old craftsman standing in front of him, he immediately bowed to them with fear...

"We should not be able to receive this gift. We should be asking you for advice."

Chen Yi quickly helped Jin up, looked him up and down, smiled and exclaimed: "I am worthy of being a craftsman who can make Anlutu. Today, I really refreshed us!"

The craftsmen and workers on the side also praised the experts, and all the skilled craftsmen were piled up on him.

It was fine if he didn't say it, but Jin immediately blushed and repeatedly pushed him.

Chen Yi only thought he was humble and admired Ling even more. Unexpectedly, in Ling Ling's heart, she just thought guiltily: "It's not me, these are all thought out by Heifu, I just did it..."

But Heifu warned him about the consequences of the matter being exposed, so Jin could only hide the matter in his heart.

"Can this thing be named?" Chen Yi was very excited and turned around the instrument. After carefully observing the cam and connecting rod, he praised it at the intersection.

"Called water pestle."

Jin said: "Because it can drive several pedals to move, my wife gave it a name, called Lianji Water Mold..."

"Linking the water pestle."

Chen Yi exclaimed: "Okay, legend has it that in ancient times, Shennong made pestle and pounding to help all the people. You made a pedal mortar two years ago, and used the weight of your body to practise the mortar. The profit is twice as good as a pounding pestle. Today, you set up a clever mechanism to pound water and pound it, and the profit is ten times better than a pedal mortar!"

As an old craftsman, Chen Yi could see the great use of this thing: as long as the water flows and the water wheels are constantly stopping, the four pestles can continue to move, day and night!

They checked the strength and found that it was no less than that of an adult who lifted a hammer and smashed it. Moreover, people had to rest and sleep, eat and drink water, and might be lazy, but they would not be able to even have a water mill. In this way, a machine mill was at least equivalent to ten adult laborers!

"If fifty horses can be set up here, wouldn't it be equivalent to giving the bronze official five hundred more men?"

Thinking of this, Chen Yi was excitedly holding the fearful and terrified Jin, raised his hand high and said to everyone:

"Any craftsman is called cleverness when it is beneficial to others, and a clumsy when it is not beneficial to others."

"The so-called skilled craftsmen in the palaces of the princes cast exquisite ritual instruments and carved jewelry. They can do their best, but they are not conducive to the people. In my eyes, they are just a group of clumsy craftsmen!"

"The governor of Shu County Li led the Dawei we built to irrigate thousands of acres of land and let the water and drought be passed by people. It is a great trick to make the city of Shu."

"Today, one machine-connected water mill made by Citron is equivalent to ten more manpower out of thin air, which is small!"

...

In the afternoon, Heifu also accompanied Li Youlai to watch the "Lianji Water Molding". Everyone was crowded by the water. When he watched the wooden pestle operate on its own under the driving force of the water wheel, he exclaimed a burst of exclamations. Heifu whispered to Jin behind and learned from the old worker Chen Yi's praise from Jin.

"Small?"

Heifu smiled and said, "I don't agree with this. Chen Yi only saw the stream in front of him, and only saw it affecting the Tongguan. But he forgot that there are thousands of streams in this Nanjun and tens of thousands of rivers in the world. If this thing can be promoted, there will be hundreds of millions of people who have received the quilt. How could it be less than Dujiangyan... than the creek?"

Moreover, the water pestle can not only be used to treat ore, but also to pound rice and pound medicine, which has a wide range of uses.

Sometimes, the black man should not sigh that ancient inventions and creations do not need to be fancy or complex. Sometimes, the simpler things are, the easier it is to be forever.

Although this is something that our ancestors invented in the Western Han Dynasty, until the beginning of the reform, in the south, water mills were everywhere for helping people pound grain and grinding noodles. There was a place in Heifu's hometown in his previous life. His grandfather worked in the grain management office when he was young, so he was sent to the water mills room for several years. Heifu ran to play when he was a child, so he had some impression...

In Heifu's eyes, the meaning of water mills is more than that. This should be the first time that people in China have taken the initiative to use water power to convert water into power.

When the window paper "people can use hydraulic power" is pierced, it can be imagined that craftsmen from all over the world will spontaneously study and understand its principles. Within a hundred years, water mills, water drains, water trucks and other things can be created. With Hefu's suggestions, the time will even be shortened to within ten years!

"I just hope that these things can really free more people from the heavy labor and slowly change this era."

Thinking of this, Heifu joked: "Sister, you are already a master of skill. You are just around the corner!"

"I don't ask for any rewards and titles, as long as it's not exposed."

Jin was still nervous. In his opinion, this was a fraud of rewards and rewards. Once exposed, it would be punished!

"I have told the county magistrate that I realized this thing by the water and told you that even if someone questioned it, you and I can be innocent."

Hefu comforted Jin so much, but he still wanted to let Jin get this credit. He has specialized in his profession. Although Hefu has ideas, it is his technology that makes this idea come true. In the future, Hefu has more to rely on him.

At this time, Li You had already ended the inspection with satisfaction. In this way, the Haikou that Heifu boasted that day was fully realized. If dozens of water pestles could be added to the surrounding streams and rivers, the copper officer could hand over more copper ingots and allow the casting workshop to create more weapons. Before the war begins, the arsenal's shortfall will be filled!

Li You finally sighed: "My father once showed me an article by Xunzi, which said that when climbing a high place and rushing, the arms are not lengthening, but those who see far away; when shouting with the wind, the sound is not increased, but those who hear it are obvious. Those who pretend to be a carriage and horse are not profitable, but those who lead thousands of miles; those who take boats and oars are not able to water, but they are cut off rivers. A gentleman is not born in a different way, but he is good at using things!"

"Today, there are Zuo Bing Cao Shihefu and Anlu County Craftsman. They used the water power to make a water pestle that can achieve several times the effect!"

Everyone responded in unison, including the chief of the county magistrate who came to see the lively scene after hearing the news. He nodded slightly, thinking about something.
Chapter completed!
