Wei Zheng was praised by Li Shimin as a mirror above the temple.

As a person who even Li Shimin is afraid of, everyone is afraid of it in Chang'an.

No matter if you are the emperor and crown prince or a rank official, as long as it falls into his hands, no one can escape.

In Yuanling's historical memory, Wei Zheng was a righteous and upright famous minister, who made outstanding contributions to the Zhenguan rule. In his mind, Li Yuanai's memory was like a demon, and he could not avoid it.

In his early years, because he likes gambling, he wrote a book for Wei Zheng.

Li Yuan was still there at that time. Li Shimin wanted to turn big things into small things. Wei Zheng refused to let him go and had to come to a conclusion, but the matter was a big deal.

From then on, Li Yuanai had to walk around when he saw Wei Zheng, for fear of getting him a minor problem.

But at this moment, Yuan Ling appeared in the Wei Mansion and respectfully handed over a letter of worship. In order to avoid refusal to see him, he specially brought a sketch of a cart.

Wei Zheng received news that King Li Yuanai of Shang asked for a meeting and was resting on the couch: In recent years, he has become increasingly inadequate, and the daily affairs in the temple made him feel exhausted. He didn't know where to start. He took a short rest as soon as he returned to his house before he had the energy to deal with the remaining trivial matters in the temple.

Wei Zheng, who received the visiting letter from his servant, was full of doubts. He had very few friends, only two or three confidants, and had almost no contact. It was really rare to receive the visiting letter.

When he casually opened the prayer, the first thing he saw was the sketch of the cart in it. Wei Zheng looked at the sketch with his casual eyes and brighter, and he was even a little excited. He didn't read the content of the prayer at all, and said directly: "Come here, please invite the King of Shang into the lobby to speak."

Wei Zheng did not rush to leave. The identity of the King of Shang was nothing in front of him, the prime minister.

A similar thing happened a year ago. As Li Shimin's sons showed wiseness, the emperor, who was born noble, naturally enjoyed extraordinary treatment in Chang'an.

However, Wang Gui and Wei Zheng could not tolerate sand in their eyes.

Wang Gui directly submitted a memorial: "Officers above the third rank meet a prince on the road and need to get off the car and get off the horse to show respect, which violates the standards of etiquette."

Li Shimin immediately became displeased and said angrily: "If you are one of you, you are in a high position and a powerful position, can you look down on my son?"

Wei Zheng did not care about Li Shimin's face and directly argued: "From ancient times to the present, the princes have been listed below the Three Dukes. Now the third ranks are all the emperors and eight chiefs. Getting off the chariot for the prince is not the courtesy that the prince should receive. If it is sought from the old examples, there is no basis for proof; if it is implemented now, it is also contrary to the laws of the country..."

Li Shimin, who was directly criticized by a long and long speech, admitted defeat and agreed to Wang Gui's request, weakening the position of the prince.

This is true for Li Shimin's own sons, let alone princes like Li Yuanai.

Wei Zheng carefully read the prayer letter written by Yuan Ling, carefully looked at the sketch of the cart before walking towards the lobby of the mansion.

Yuan Ling felt a little disappointed when he saw Wei Zheng at first sight. In his impression, Wei Zheng should be a person with a graceful and elegant character, but he didn't expect to be a bad old man with a look of shame. He bent his back slightly, and his eyes were blurred with a thin line.

If it weren't for seeing it with your own eyes, Yuan Ling would never have thought that the famous Wei Zheng would look like this.

"I've met Shi Zhong Wei!"

However, Yuan Ling dared not underestimate the old man in front of him. He is definitely not an easy person who can leave a reputation in history.

Wei Zheng nodded and replied, and spoke directly to the point: "Is this sketch drawn by the King of Shang? It is somewhat different from what someone saw. What is the use of this shaft as a wheel or not?"

Yuan Ling was stunned when he heard this and was instantly impressed.

Wei Zheng didn't seem to be proficient in craftsmanship, but with his extraordinary talent and experience, he directly penetrated the core key vertical wheel horizontal axis of the cylinder car.

"I call this axis a vertical wheel horizontal. It is the key to linking the vertical gear and the horizontal gear and the large vertical wheel. It rotates the vertical gear with a small force, and drives the large vertical wheel through this vertical wheel horizontal, thereby generating ten or even a hundred times the force. The keel water truck that is circulated in the world is consistent with the basic principles of this cylinder truck, but I think that the power of water has the power to destroy and destroy. If it can be used, it can benefit the world."

Wei Zhengbao looked at Yuan Ling with the same strange look. At first, he did not think that the car was the result of the nonsense Shang King in front of him, but he did not point it out, and wanted to find out the true hero behind the scenes and benefit the world. However, Yuan Ling's words directly made the prime minister, who was the most prestigious in the temple realize that he was a villain in vain.

If I hadn't had a thorough understanding of this car and asked casually, how could the other party answer so neatly?

Wei Zheng calmed down his contempt and asked for advice humbly: "This thing is indeed extraordinary. If you are not good at this, you can only see the general idea. The real details and wonderful uses are also required. Please indicate it."

Yuan Ling heard Wei Zheng's attitude change and hurriedly said, "This equipment can be called a barrel car. According to my plan, there will be three forms. This is just one of them, referred to as a water drum car. It directly uses the power of the water flow, and the water rushes the water from the barrel into the sink next to the wheel and flows into the field. This series of operations does not require human control at all."

Wei Zheng was very interested at first, but he was so quick-witted that he shook his head slightly and said, "It's useful, but not very useful."

Yuan Ling knew that Wei Zheng had seen through the biggest shortcomings of the water-rotor truck.

Water drum trucks need enough hydraulic power to operate. Where there is enough hydraulic power, there is no problem of water shortage.

The descendants of Yan and Huang are the world's hard work and hard work. What the people lack is not labor, but the key places and key water.

The water-rotor truck looks tall and does not require labor, but it is just icing on the cake.

Yuan Ling took out the information he prepared from his arms and handed it to Wei Zhengdao: "There are some concerns among the Wei Shi Center. The water drum truck is suitable for places with abundant water resources. This animal drum truck can solve this problem. The gears of the animal drum truck are much more complex than that of the water drum truck. It is suitable for ditches with shallow water and insufficient water power. However, as long as the water in the river canal is pumped up and reaches a certain amount of power, it can still operate independently."

When Wei Zheng heard this, his eyes narrowed slightly opened. That's true. This water drum truck will benefit the people in the dynasty who have difficulty in obtaining water.

Yuan Ling seemed to have returned to the situation where he recommended himself for the project, and he kept introducing the last high-rotating truck: "As far as I know, the banks of large canals such as the Yellow River, the Yangtze River, and the Huai River are the most important grain harvest areas in our dynasty. However, natural disasters are ruthless, and the floods are all fertile soil, and all the fertile soil is water grains without harvest. In order to avoid floods, the court usually builds river embankments and dams to protect the people on both sides of the country. However, the dam inevitably increases the difficulty of water withdrawal. The high-rotating truck is born for this... You see..."

He pointed to the drawing and said, "Please a large rotating wheel on the shore and in the water. The wheel in the water must be immersed in half a wheel. The upper and lower wheels are wrapped around a long chain ring connected by ropes and small bamboo tubes. No matter how deep the river bank is, it can be easily irrigated."
