My brother Ying Zheng, who dares to kill me?.

Chapter 846: The rivers, lakes, seas, sun, moon, mountains and rivers should all serve as corvée laborers for the Qin Dynasty! Even if you don't have money, you can still work like a ghost!

Ying Zheng stared at the water-powered millstone in front of him, and his legs unconsciously stepped onto the steps, muttering in a lost voice:

"Water keeps flowing, and the mill keeps turning!"

"The grinding will never stop, and the powder will never stop!"

"Using water as labor, the workmanship is beyond compare!"

Whether it was the Chang'an car, the Chang'an plow or the blast furnace, the shock they brought to Ying Zheng was far less than that of the flat-wheel water mill in front of him.

Changan cars, Changan plows and other items did save a lot of manpower, but they still relied on human power as their main source of power.

However, the power source of this flat-wheel water mill has changed from human power to natural power!
During the grinding process, people change from power providers to auxiliary supervisors.

This not only saves a lot of manpower, but also opens the door to a new world for Ying Zheng.

Everything in Daqin must obey my orders.

I can command the people of the Great Qin to serve me, so why can't I command the rivers, lakes, seas, sun, moon, mountains and rivers of the Great Qin to serve me? !

After opening his mind, Ying Zheng suddenly realized that his mobilization of the Qin national strength was far from enough!
Han Cang did not think so much or so far.

He passed Ying Zheng like a gust of wind and rushed to the edge of the millstone.

First, pick up a handful of slag powder with your fingers, rub it between two fingers to feel its particle size, and then grab another handful of slag powder and make a fist!

Fine slag powder slid down from his trembling fists, and Han Cang shouted excitedly: "This is a weapon to revitalize the country!"

"It is a powerful tool for the prosperity of the country!"

"Lord Chang'an!" Han Cang suddenly turned his head and looked at Ying Chengjiao, asking eagerly: "If there is no one who is favored by heaven and earth, can this thing be built?"

Ying Chengjiao was somewhat speechless and said, "It's just a flat-wheeled water mill. Why does it need the grace of heaven and earth?"

“See that wooden wheel under the bridge?”

"Hashimoto..."

Before Ying Chengjiao could finish his words, he saw Han Cang rush to the bridge, sticking his head out and trying to look down.

However, the underbridge structure, which had been greatly reinforced for strength, completely blocked Han Cang's view.

After estimating the distance between the bridge and the water surface, Han Cang made up his mind and jumped directly from the bridge!
Ying Chengjiao cried out in surprise when he saw this: "Han Shangqing!"

"Hurry up and save people!"

With a shout, Ying Chengjiao took two steps at a time and rushed to the edge of the bridge. Then he jumped into the air and stepped onto the railing. He exerted force on the muscles of his right leg and urged his body to leap into the water!

Ying Zheng, who was immersed in the new world, was just awakened by the sound of Han Cang falling into the water, and then he saw the scene of Ying Chengjiao jumping into the water.

In a state of shock, Ying Zheng shouted in a panic, "Help!"

While shouting, Ying Zheng also ran towards the bridge, but was tightly held on both arms by Lu Buwei and Wei Zhuang.

"My lord, you can't jump!"

"Your Majesty, please trust Chang'an Jun! Chang'an Jun has already jumped into the water, you can't jump again!"

Dragging Lü Buwei and Wei Zhuang, Ying Zheng walked to the bridge step by step, and saw dozens of people including Bafu, Guafu, Meng Yi, Wang Bo and others jumping into the river together. Ying Chengjiao had even grabbed Han Cang by the back of the neck.

Only then did Ying Zheng feel a little relieved and shook off Lu Buwei and Wei Zhuang.

"Let me go!" Han Cang stared at the wooden wheel under the bridge with burning eyes, and shouted enthusiastically, "I can swim! I won't drown! Let me take a closer look! Look carefully!"

Ying Chengjiao shouted angrily: "Go ashore first!"

With the help of everyone, Han Cang was finally pulled ashore.

But after landing, Han Cang's eyes were still fixed on the wheel under the bridge, his eyes full of enthusiasm and realization: "The water wheel below this flat-wheel water mill and the stone mill above are connected by a wooden stick."

"The water flow drives the wooden wheel to turn, the wooden wheel drives the wooden stick to turn, and the wooden stick drives the millstone to turn."

"That's it! That's it!"

"Such an ingenious creation is actually so simple!"

"Chang'an Jun is a great talent! A great talent!"

When Han Cang first saw the flat-wheel water mill, his worldview trembled.

Han Cang even thought that Ying Chengjiao was driving the mountain gods and water ghosts to help him turn the mill.

It was not until Han Cang jumped into the water and saw with his own eyes the wooden wheel turning rapidly under the action of the water flow, and the wooden stick driving the millstone turning synchronously with the wooden wheel, that Han Cang finally understood.

It turns out that all this is so simple!
Suddenly, Han Cang's collar was grabbed by Ying Chengjiao.

With great force, Ying Chengjiao lifted Han Cang up and roared angrily: "Do you know that I deliberately closed the front bank of the river to make the water flow faster here?"

"The rapids beat the wheels, and many wheels turned simultaneously."

"Once Han Shangqing is caught in the wheel, he will die in an instant!"

"Han Shangqing, do you want to die?!!"

Having resolved the doubts in his mind, Han Cang finally turned his gaze towards the rushing water and realized how fast the wooden wheel was turning!
Although Han Cang can swim, he is already old after all.

If Ying Chengjiao and others had not rescued Han Cang, once he was caught in the chaotic water flow near the wooden wheel, he would have been minced into pieces by the wooden wheel today!
A strong fear surged in his heart. Looking at Ying Chengjiao, who was soaked all over, Han Cang said with a feeling of gratitude and shame: "I know I was wrong!"

"Thank you, Chang'an Jun, for saving my life!"

"I will be more cautious in the future and will never be as reckless as I am today!"

Han Cang's sincere attitude of admitting his mistakes made Ying Chengjiao not know what to say anymore. He let go of his hand and smoothed the wrinkles on Han Cang's collar. Ying Chengjiao tried to persuade him: "The current Great Qin is at a critical period. If Han Shangqing is not in charge of the grain management office, who can control so much money and grain for our Great Qin?"

"Besides, I was raised by Han Shangqing. In my heart, Han Shangqing is truly my elder."

"If Han Shangqing dies because of the craftsmanship I have developed, I will regret it for the rest of my life."

"I hope Mr. Han will be kind to himself!"

Han Cang was both moved and ashamed, and he bowed his hands loudly and said, "Your Majesty, I know I was wrong!"

Seeing from afar that Ying Chengjiao still had the strength to carry the people, Ying Zheng breathed a sigh of relief. He was still running wildly, but he shouted loudly: "Go and get the clothes quickly and give them to you, my dear ministers!"

"Brother, Han Shangqing, are you alright?"

Ying Chengjiao shook his head and said gently, "I'm fine, don't worry."

Han Cang bowed again and said ashamedly: "I am fine, thank you for your concern!"

Ying Zheng finally ran to and stood in front of Ying Chengjiao.

After carefully confirming that Ying Chengjiao had no wounds, Ying Zheng immediately ordered: "My brother, change your clothes first!"

Then Ying Zheng looked at Han Cang, hating him for not fighting back, and said, "Han Shangqing!"

"I know that Han Shangqing cares about the people of Qin, but he must not be so impulsive and reckless!"

My dear, even if you want to jump into the river, you can't do it in front of my brother!

If you die, I will be heartbroken.

But if you, my dear minister, implicate my younger brother, I will be in unbearable pain!

Han Cang raised his head, looked at Ying Zheng with eager eyes and said: "Your Majesty, I can't help but be impulsive!"

"I have just examined it carefully. This flat-wheel water mill is indeed ingenious, but its structure is quite simple."

"With the strength of our Great Qin official workshop craftsmen, we can completely make it ourselves!"

Ying Zheng was overjoyed and quickly looked at Ying Chengjiao and asked, "Brother, is this true?"

Ying Chengjiao had just taken off his soaked linen clothes and was wiping his strong and muscular body with the silk cloth handed to him by the fortune teller. He asked in return, "How many people in my Great Qin eat noodles?"

The significance of the stone mill is to grind lumps of materials into powder. Its main use among the people is to grind flour!

Nowadays, people in the world have long added water to flour to make dough, then put the dough into a pot to cook, and then put it into various soups to eat.

But for the vast majority of people in this era, being able to eat enough is the most important thing, and whether the food is good or not is not even within their consideration.

Not to mention how much manpower is needed to grind rice into flour, the grain and millet husks wasted in the grinding process alone are far beyond the tolerance of most people in the world!
Han Cang said repeatedly: "There are indeed not many people in my Great Qin who eat noodles."

"But our Great Qin can sell noodles to other countries and make a lot of money!"

Ying Zheng, Lu Buwei and other Qin monarchs and ministers all nodded in agreement.

There are indeed not many people in Daqin who can afford noodles, but there are many people in Qi who can afford noodles.

If Daqin can develop flour technology, flour will surely become a major advantageous industry for Daqin's export and foreign exchange earnings in the future!
However, Ying Chengjiao shook his head and said, "There is no need to use precious manpower to earn money from other countries."

"The Japanese king will take all the money of other countries!"

Han Cang: ...

The ruler and ministers of the Qin Dynasty: ...

What he said makes sense!
I was speechless!

After wiping his wet hair with a new piece of silk cloth, Ying Chengjiao said seriously, "If we really want to mobilize the people's power and build more facilities, I think it would be better to build a flat-wheel water mill instead of a flat-wheel water mill."

Ying Zheng's heart suddenly warmed up: "Can water power not only be used to grind rice, but also to mill rice?"

Ying Chengjiao nodded and said, "Although grinding and milling are different, the principles of water mill and water mill are the same."

"Similarly, the water wheel under the bridge drives the wooden stick, and then a horizontal wooden pole is connected to the wooden stick, and the end is connected to a thinner stone mill."

"The rotation of the water wheel can drive the stone mill to rotate around the millstone."

"Then, grooves are cut on the millstone in the path of the millstone's rotation, and the millet is placed in the grooves, and the work is done."

As Ying Chengjiao finished speaking, the scene fell into silence.

Even the assistant ministers such as Meng Yi were constructing images in their minds, trying to verify the feasibility of Ying Chengjiao's words.

After a dozen breaths, Qi Ai said decisively: "It's feasible!"

“Although the flat wheel water roller is a little more complicated than the flat wheel water mill, it is definitely feasible!”

As a master stonemason in the Ministry of Works and a craftsman who built the flat-wheel water mill, Qi Ai's words were particularly confident.

Han Cang was trembling visibly, whether from the cold or excitement, and he murmured incoherently, "If this thing can be used to grind rice, how much manpower can it save for our Great Qin?!"

Ying Zheng and other Qin emperors and ministers were all immersed in beautiful fantasies.

But Ying Chengjiao seemed to be afraid that the hearts of the Qin monarchs and ministers were too healthy, so he spoke again: "If you use a flat-wheel water mill to grind rice, the water flow requirements are higher."

"In places where the water flows slowly, you can build a vertical wheel water mill to pound rice."

Ying Zheng's eyes widened slowly, and he asked in disbelief: "Can our Great Qin still collect water-pounded rice?!"
