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

Chapter 847: The Birth of the Soul of the Industrial Devil! Have you forgotten that you are my subject?

Ying Chengjiao nodded as if it was a matter of course, and pointed upstream and said, "The workshop in Lantian County built a vertical wheel water mill to crush large pieces of ore and slag, so that the flat wheel water mill can process them again."

"Compared to..."

Before Ying Chengjiao could finish his words, Ying Zheng lifted his crown with his right hand, stretched out his long legs and ran wildly in the direction of Ying Chengjiao's finger!

Old ministers such as Lu Buwei did not look old at all at this moment. They were actually in their sixties or seventies and followed Ying Zheng closely.

Han Cang let the cool autumn breeze blow on his body, his wet long hair fluttering in the wind. He rushed forward like a water ghost who had just crawled out of the river, and even ran in front of Ying Zheng, without even noticing that the end of his hair splashed Ying Zheng's face!
Ying Chengyu:...

The silk cloth used to wipe the water froze in the distance. Ying Chengjiao murmured involuntarily, "Can my elder brother and all of my colleagues run so fast?"

Liu Ji was also shocked and whispered, "Are the king and all the superiors so... generous?"

"Even when Liu was fleeing, his escape was no more than this!"

Those who know understand that the group of people in front of them are the ones standing at the pinnacle of power in the current Qin Dynasty.

If you don’t know, you might think that these are a group of defeated soldiers being hunted down!

He quickly wrapped his hair with silk cloth and put on a dry linen shirt. Ying Chengjiao also chased after him, shouting, "Hurry up and put clothes on Han Shangqing!"

"If Han Shangqing doesn't want to, we have to hold him down and force him to put on his clothes!"

"Han Shangqing is old, he must not stand in the wind and get cold!"

After a long period of war and chaos, the Qin emperor and his ministers finally saw several huge wooden wheels standing in the river upstream.

These wooden wheels are different from the flat wheels lying horizontally in the river. Instead, they are erected on both sides of the river. Thirty percent of the wooden wheels are hidden in the river water, and seventy percent of the wooden wheels are exposed on the river surface.

Ying Zheng's pace gradually slowed down, and he looked at the slowly turning huge wooden wheels with a mesmerized look, as if he was afraid of disturbing them. He murmured softly: "Is this the vertical wheel water mill that my brother mentioned?"

Dozens of craftsmen operating water mills stood up in panic and bowed in unison: "Greetings, Great King!"

But they did not wait for Ying Zheng's response.

Although he had not seen any further details, just the sight of these wooden wheels that turned by themselves under the action of water without the need for human power had already made Ying Zheng feel a strong sense of beauty.

Ying Zheng couldn't describe how beautiful this was, nor could he think of a suitable adjective.

But Ying Zheng was already intoxicated by this beauty and couldn't extricate himself!
In a trance, a young cocoon was born next to Ying Zheng's soul of infrastructure maniac.

What is being nurtured within it is the soul of the industrial demon!

Ying Chengjiao finally caught up with Ying Zheng and glared at him helplessly: "Brother, why are you so flustered!"

"If any of my old ministers were to fall or get hurt today, I would like to see how distressed you would be!"

Ying Zheng finally came to his senses. Looking at the old ministers behind him who were panting and trembling, he showed some shame in his eyes and said without hesitation: "This is my fault."

"General Meng, go and help the nobles!"

Then Ying Zheng couldn't wait to ask, "Is this the vertical wheel water mill that my brother mentioned?"

Ying Chengjiao nodded slightly, told the craftsmen to do their respective duties, and introduced them, "Brother, what you said is correct."

"Compared to the flat wheel, the vertical wheel can generate much less power. Although it can drive the stone mills used in ordinary villages and can be used to pound rice, it is almost impossible to drive the stone mills weighing thousands of kilograms like the one used in the Lantian workshop."

"But the advantage of the vertical wheel is that it does not require rapids, and the requirement for river flow speed is much lower than that of the flat wheel, which is more suitable for use in Guanzhong."

“The vertical wheel does not need to build a bridge over the river, but can be directly erected on the edge of the river bank, making it easier to build on a large scale across the world.”

The power of a flat wheel is much greater than that of a vertical wheel, but it is also much more difficult to build and has much higher requirements for water flow than a vertical wheel.

Therefore, throughout the entire agricultural era, no matter how the flat wheel and the vertical wheel developed, the vertical wheel was everywhere, while the flat wheel mostly served only official workshops, built by local governments or even directly by the court. When he walked to the vertical wheel, Ying Chengjiao pointed to the wooden stick on the side of the vertical wheel and said, "The principle of the vertical wheel is the same as that of the flat wheel. Both use water flow to drive the wooden wheel to rotate, and then the wooden wheel drives the wooden stick to rotate."

"There are three planks at the end of this stick."

"Next to these three wooden boards, there are three wooden hammers placed on the horizontal bar."

"The three wooden boards rotated with the stick, pressing down the tail of the hammer, causing the head of the hammer to rise."

"When the wooden board turns out, the pressure on the tail of the hammer disappears, and the head of the hammer will smash down heavily!"

As Ying Chengjiao spoke, the pestle made of pure steel was raised high, and then smashed heavily into the mortar filled with ore.

"Oh!"

With a dull thumping sound, the slag in the mortar became noticeably finer.

Ying Zheng's eyes shone brightly, and he nodded repeatedly: "The principle behind this is exactly the same as the flying stone cart made by my brother!"

"They all accumulate power first, and then release the restrictions, releasing all the accumulated power suddenly!"

"It's just that my brother replaced the animal power of the flying stone cart with the power of rivers."

"Although I don't get much each time, I can do it without sleep!"

Ying Chengjiao smiled happily: "Big brother is teachable!"

Ying Zheng glared at Ying Chengjiao with amusement.

Can I be taught?

In this whole world, only you dare to say such words!

Han Cang, who was forced to put on his clothes, finally arrived late.

Watching the rising and falling of the water mill, Han Cang approached the water mill with light steps and shining eyes, like a perverted man who had seen a peerless beauty. However, under Ying Chengjiao's deathly gaze, he could only stand beside the water mill and dared not get too close.

He watched helplessly as the pestle hit the mortar again and again, smashing the large pieces of slag in the mortar into small pieces or even into debris.

While Ying Chengjiao was not paying attention, Han Cang quickly reached into the mortar with his right hand, scooped up a handful of debris from the mortar and rubbed it with his fingertips to feel it.

Then, Han Cang's eyes lit up with excitement and he whispered, "Such hard slag can be crushed easily, let alone corn!"

"Chang'an Jun!"

Han Cang suddenly raised his head and looked at Ying Chengjiao, and asked with a trembling voice: "Isn't this thing worth telling the king about?"

Ying Chengjiao looked at Han Cang with some resentment.

My eldest brother had not originally pursued the matter, but you took the initiative to bring it up?

Han Shangqing, have you forgotten that you are my subject?

As expected, the ecstasy in Ying Zheng's eyes gradually turned into helplessness and hatred for his lack of fighting spirit. With his finger pointing up at the water mill, Ying Zheng asked solemnly, "My brother wants to complete his studies in the art of steelmaking, and then tell me about the blast furnace and steelmaking techniques."

"Brother Nai thinks that although your brother's view is too shallow, it does make some sense after all."

"But this vertical wheel water mill is related to the agriculture of Qin!"

"My dear brother, isn't this thing worth telling you about?"
