Otaku Engineer in Great Tang Dynasty Chapter 1400: Wei Zheng is back, improving the waterwheel! (Thanks to Jiayan for the reward!…

"Waterwheel?"

Cheng Yaojin heard Li Zexuan say that he was going to build a waterwheel, he couldn't help but wonder, after thinking for a moment in his heart, he couldn't help but say: "Xiaoxuan, you are right that the waterwheel should be overturned. Right?"

Listening to Cheng Yaojin's words, Li Zexuan realized that he had said the wrong thing. According to the memory in his mind, it seems that there is no such thing as a waterwheel. On most occasions, people call it a rollover, so he quickly changed his words. Said: "Uh! Yes, Uncle Cheng, it just overturned!"

In folklore, the earliest water-drawing device used by the ancients was "jugao". Simply put, it was a strong wooden pole with a wooden bucket hanging on one end for water, and the other end was used Hanging heavy objects similar to current weights uses the lever principle that Chinese people have discovered many years before foreigners to achieve the purpose of saving the power of drawing water.

The waterwheel in Chinese official written records did not appear until about the Eastern Han Dynasty. At the end of the Eastern Han Dynasty, when Emperor Ling of the Han Dynasty, Bi Lan ordered Bi Lan to build a "turnover", which had basic installations such as wheel axle groove plates. It’s also said that during the Three Kingdoms period, Wei people and horses also made rollovers. "Wei Lue" said: “Ma Jun lived in the city of Kyoto.

However, the waterwheel at that time was just some basic ideas, and some basic structures derived from it, and its driving method was relatively backward driven by humans. This is the first stage of China's waterwheel development, and it is also the most primitive stage.

Cheng Yaojin couldn't help shaking his head and said: "Xiao Xuan, this dump truck can be used to irrigate a small amount of land, but if there are thousands of acres of land, it is not as convenient as using human to lift water!"

Qin Qiong nodded and said: "Zhijie is right. This waterwheel is indeed not suitable for large-scale farmland irrigation. It is time-consuming and labor-intensive. Instead of this, it is better to carry water!"

Li Zexuan thought for a moment, knowing that Cheng Yaojin and Qin Qiong should have misunderstood, so he smiled slightly: "Uncle Cheng, Uncle Qin, the rollover I said is not the same as before. It doesn't need It is driven by manpower, but directly driven by water. Its water output speed is much faster than that of previous rollovers, and it can run around the clock, so instead of calling it a rollover, I am more used to calling it a waterwheel~!"

When Cheng Yaojin heard this, his eyes were as big as a copper bell. He was surprised: "There is this kind of waterwheel that can be turned by the flow of water? Xiaoxuan, are you lying to the old man?"

Qin Qiong and Niu Jinda also called out incredible.

Li Zexuan said with a smile: "How dare my nephew lie to some uncles? After the morning session, my nephew will go back to Yunshan to draw the drawings. It should be a few days before the workshop will be able to tell what I said. Plant a waterwheel!"

The waterwheel he said that can use the water to run on its own is called a "tube car" in history. It originated in the late Tang Dynasty and flourished in the Song Dynasty.

Since its invention in the Eastern Han Dynasty and Three Kingdoms era, the dump truck has been stagnant in the stage of manpower operation. It was not until the emergence of the drum wagon that this situation was broken. It was driven by hydraulic and animal power to finally liberate the manpower from the dump pedal. The ``tube car'' not only has better irrigation efficiency than the previous rollover, but also saves manpower and material resources. It is loved by the subsequent generations of kings and promoted in life.

Also, Li Zexuan does not intend to copy the drum wagons in history as they are. He will optimize and transform them on the original basis, adding gears, bearings and other transmission mechanisms to key parts to further optimize the operation efficiency of the water wagons. Friction loss. Now his workshop definitely has this technology and strength!

At this time, Li Zexuan had to admire his foresight. After he traveled to Datang, the first major thing he did was to establish the Qiquge Workshop. Now, most of his honors and disgrace are related to this work. Fang related~!

"Haha! Good! By then, Xiaoxuan, after you build this kind of waterwheel, you must tell me Lao Cheng! The old man has lived for most of his life, and has not seen a waterwheel that can move by himself, haha!"

Cheng Yaojin laughed excitedly.

Li Zexuan nodded and said: "Definitely, definitely~!"

While talking and laughing all the way, I soon came to the palace. The fifty thousand left guards naturally couldn't enter the palace. When they were on Suzaku Street, they had already turned to Daying. The important generals in the army followed Li Er into the palace and accepted the reward!

There is nothing wrong with Li Zexuan, he just stood there dozing off, and vaguely heard how much money was rewarded by Yuchi Jingde, Chai Shao, etc., the silk, silk, and food, etc., and then he quickly Into the dreamland!

Yes, I just fell asleep while standing!

After spending so long in the court hall, Li Zexuan had already practiced the ability to stand and sleep on one hand. Speaking of this skill, he still learned this skill from Cheng Yaojin. Old Cheng has been in court for more than ten years. There is a lot of fun in this respect than Li Zexuan~!

"Your Majesty, Wei Zuocheng has returned to Beijing and is now outside the Tai Chi Hall~!"

In the dizziness, a shrill voice from the hall awakened Li Zexuan from his sleep. When he recovered, he couldn't help but stunned: "Wei Zheng is back? No, no! No! No! Sleep again! If Wei Tanzi read it, he will definitely take part in the book!"

Li Zexuan quickly wiped the corners of his mouth, pretending to be vigorous, and stood up straight.

Speaking of this kind of dozing off in the court hall, basically every minister has done it. Therefore, when everyone sees it, they will open one eye and close one eye to each other, but their eyes Wei Zheng, who doesn't have the sand, is different, from waking you up, and from spraying you in the court to ignorance and resignation!

Li Zexuan’s position in the court is very close to Wei Zheng, and there are only two people in the middle. I don’t know if Li Er intentionally or unintentionally, this position is specially arranged for him, and he is not allowed to be private. transposition!

So as soon as I heard that Wei Penzi was back, Li Zexuan's sleepiness immediately disappeared!

"Oh~? Wei Aiqing is back? Please come in soon~!"

Li Er, who sat on the top of the head, said with joy at this moment.

It’s just what Old Li thinks in his heart at the moment, so I don’t know. After all, when Wei Penzi comes back, he will often put pressure on Li Er. As soon as there is something wrong with Lao Li, Wei Penzi will open it directly. spray!

"Here~!"

The servant left with his hands. After a while, Wei Zheng walked in, his face still looked like a dusty servant, he bowed to Li Er and said: "Old minister Wei Zheng, see your majesty!"

To tell the truth, since leaving Chang'an during the first lunar month and heading to Henan Road, Wei Zheng has missed Li Er a little after not going to court for such a long time. This is not a basic love, but a relationship between the ruler and the minister! Lao Wei respects and loves Lao Li from the heart, and hopes Lao Li can become a famous emperor through the ages!

Especially after experiencing a rebellion and nine deaths in Henan Province, Wei Zheng is even more eager to return the court! So as soon as the processing on Henan Road was completed, he returned non-stop!

"Wei Aiqing exempted the gift, now I go to Henan Province, Aiqing has worked hard!"

Li Er quickly said "excitedly".

Although Wei Zheng has been irritated before, but after Wei Zheng has not been in court for so long, Li Er is still a little uncomfortable! Now that Wei Zheng came back, Li Er was inexplicably relieved for some reason!

"Thank your majesty!"

Wei Zheng stood up, and said: "Your Majesty, on the first month of the first month, I was ordered to send Cui Junchuo back to Zhengzhou, and to pick up the illegal activities of the Cui family over the years, and to clear out the Henan officials. During the period, Cui Junchu did not want his children to be The veteran investigated and dealt with it and conspired secretly with the Cui family of Boling and the Zheng family of Xingyang. The veteran had the help of Liu Rengui, who joined the army in Bianzhou, and escaped!

Later, His Majesty sent a large army to Guancheng to quell the rebellion. After the rebels came down, the veteran stayed in Henan Province to appease the people and investigated the officials associated with the Cui family. A total of 33 officials and all the evidence were found. To be sure, these people have now been imprisoned in the prison of Dali Temple, waiting for your majesty to send off! Fortunately, the veteran of Henan Road trip did not humiliate his life. "

Speaking of the last, Wei Zheng bowed and bowed his hands.

Li Er nodded, and said in a deep voice: "Wei Aiqing's road is extremely difficult and dangerous. In order to clear the Henan provincial officials, he has committed dangers with his own body, and has even endangered his life many times. I am very touched in my heart. Wei Aiqing’s efforts have been able to reproduce the bright universe. I decided to appoint Aiqing as Prince Shaobao, Doctor Golden Ziguanglu, and give three hundred households~!"

Wei Zheng bowed and said: "The minister thanked your Majesty~! However, when the minister came back, he saw that many farmlands had suffered a very serious drought along the way. Many people were carrying water from the river to irrigate the land. The old minister was sure Your Majesty ordered the Ministry of Households to allocate money, and the Ministry of Industry sent craftsmen to help civilians dredge the ditches and relieve the drought!"

Li Er frowned and said: "I have known about this for a long time. In a few days, the court will allocate manpower, material and financial resources to make local prefectures and county officials help the people dredge the ditches and ensure that those with lower terrain Farmland can be irrigated by river water!"

Wei Zheng breathed a sigh of relief, and said: "Your Majesty Shengming! In this way, the drought can be relieved to the greatest extent and the people's losses can be reduced!"

Obviously, Wei Zheng also understands that it is impossible to take care of all the farmland with a drought of this level nowadays. For some farmland that cannot be reached by ditches, we can only rely on the people to carry water~!

"Hey! Who said that high-lying farmland can't be watered? As far as I know, Yonganhou will build a dump truck that can move by itself to carry water from low to high places~ !"

Cheng Yaojin couldn't help but show up.

Early this morning, I was watching other people being rewarded. Cheng Yaojin thought it was quite boring. Now that he finally found such an opportunity to show off, how could he miss it?

In the early days of the Tang Dynasty, the court was relatively free. Cheng Yaojin said for no reason. No one blamed him. Instead, everyone looked at him with scorching eyes. The role of "soy sauce" has become the protagonist!

Li Zexuan couldn't help covering his face, and he secretly said that Lao Cheng was really uncomfortable. The waterwheel hadn't been made yet, so you just took it out and bragged it, didn't it be too early?

"Guogong Lu, what you said is true? Is there such a dump truck that can move by itself and carry water?"

Wei Zheng looked at Cheng Yaojin excitedly and asked.

Although he usually quarrels with him about mileage and gold, Wei Zheng still knows to put aside his personal feelings on such big disputes.

"Shit~!"

Cheng Yaojin sneered and said proudly: "My old Cheng speaks, one spit and one nail, can I still tell you whether Wei Xuancheng is not? If you don't believe it, go and ask Yonganhou!"

He looks like he is going to build a waterwheel himself!

Wei Zheng was too lazy to follow the old guys. He quickly turned his attention to Li Zexuan. At this moment, Li Er finally couldn't help but say: "Hou Yongan, just now Cheng Zhijie said, is it true?"

Li Zexuan knew that he could not continue to keep a low profile. He walked out of the civil servants team and bowed forward and said: "Return to your majesty, there is indeed such a thing. This kind of rollover is called a waterwheel by the minister. It does not require manpower to pedal. It can be operated entirely by hydraulic power. But these are just some of the ideas in the mind of the minister, and they have not been created yet. Your Majesty will give the minister a few days to know if this method is feasible~!"

Listening to what Li Zexuan said so affirmatively, the ministers couldn't help being shocked. Wei Zheng trembled with excitement. He murmured: "It's saved, now the people are saved!"

Li Er was also shocked. He looked at Li Zexuan with scorching eyes, and said, "Waterwheel? Good! In the past few days, I have asked you to concentrate on developing this waterwheel. If you do it well, I will definitely pay more attention. There are rewards!"

"Chen, follow the order!"

Li Zexuan bowed.

After all, he couldn't help but glanced at Cheng Yaojin with a grievance. The improved version of the waterwheel was originally just a casual comment in the morning. He didn't even know whether it could be built successfully, but now he was so touched by Cheng Yaojin. Nong, Man Chao knows all about it, he has to build a waterwheel anyway, and build it successfully!

……………………………

After the early dynasty came out of the palace, there was no time to gossip with Cheng Yaojin, Qin Qiong and other elders, so Wei Zheng urged Li Zexuan to go back and develop the waterwheel.

"Hou Yong'an, the drought is like a fire, but for the sake of the common people in the world, you can build the kind of waterwheel you mentioned as soon as possible! Otherwise, I don't know how many people will get nothing this year. It’s up! The old man looks at Wei really hurts!"

Although Wei Zheng didn't clearly urge Li Zexuan to roll back to Yunshan, he still saw Li Zexuan uncomfortable with his little bitter eyes. Therefore, Li Zexuan quickly replied and immediately beat the horse back to Yunshan!

In other words, although Wei Zheng likes to be **** sometimes, but this old man is thinking for the people in his heart, and it is precisely because of this that Li Zexuan respects Wei Zheng.

"Msang Gong~IndoMTL.com~You are back~?"

Han Yuxi, seeing Li Zexuan back, hurriedly greeted him and said.

"Hmm! Madam, I have something to do for my husband, so I won’t eat at noon! Don’t let people go to the study to disturb me~!"

Li Zexuan confessed to his wife and hurried to the study.

He wants to quickly draw the improved waterwheel drawing!

Not only does Wei Zheng know that drought is like a fire, he also knows.
