"The waterwheel is actually like a big turntable, and you can use wooden poles as the skeleton of the turntable, or you can use steel. The edge of the turntable is equipped with a scraper and a water bucket, and the water flow will drive the scraper to rotate, and when the scraper rotates, the bucket is filled with water and is lifted up one by one with the rotation of the water wheel. At the top of the waterwheel, the bucket is rotated by gravity, and the water in it is poured into the tank above the waterwheel, and so on, and the process from holding water to transporting water is completed.

Among them, the direction of the bucket is very important, must be against the direction of the water flow, only in this way, in order to lift the river to a high place, in addition, the main wheel of the waterwheel, to use the unique roller bearing of our workshop, reduce friction, improve the efficiency of carrying river water! Of course, for those stagnant water that does not flow, you can add a gear transmission mechanism to it, and use animal power to drive the roulette wheel to rotate!

No matter what way, it is much more convenient than the previous manpower overturn~! ”

In the afternoon of the same day, Li Zexuan brought the drawings to the Qiqu Pavilion workshop, Yan Shaoning, Fu Bo, Mo Huai, and Mo Trai all rushed over when they heard the news, and Li Zexuan spread out the drawings and carefully explained the structure and operation principle of the waterwheel to everyone.

"Ingenuity! In this way, as long as there is water in the river, this waterwheel can carry the river water ashore day and night, and if there are several more such waterwheels side by side on a section of the river, the speed of moving water is definitely enough to irrigate thousands of acres of fertile land in a short time! ”

After listening to this, Mo Huai imagined the scene of the waterwheel running in his mind, and at the end, he couldn't help but brush his beard and exclaimed.

"That's right! Compared with the previous manpower rollover, this kind of waterwheel can automatically carry water as long as it is placed on the river surface, which is not only convenient and labor-saving, but also has a large water output! You can use this to carry the river water into the ditch, so that you will no longer be afraid of drought~! ”

Fauber couldn't help but nod.

Li Zexuan smiled and said, "You are right, this waterwheel with a ditch can completely conduct large-scale farmland instructors!" Tomorrow I will go to He County to order the time to use cement to renovate all the ditches in Lantian County, Lantian County has a dam as a guarantee, you can directly release water from the reservoir into the ditch, for the village near the north of Lantian County, because the terrain is much higher than this side, you can use a water wheel to carry the water over! ”

The topography of Lantian County is higher than the south in the north, higher in the west than in the east, the Bahe River is a river that flows into the main channel of the Yellow River in the southeast from the northwest, Meicun and Hanjiazhuang, which are close to the Bahe River, directly lead out a canal from the dam, which can ensure that all the farmland can be irrigated, but like Yujiazhuang, which is close to the north, Zhuangzi wants to use the canal to lead the water of the Bahe River to the past, which is tantamount to wishful thinking, only relying on the waterwheel to carry the water in the south ditch to the north!

"Ditching with cement? Xiao Xuan, I heard you right, right? ”

When Yan Shaoning heard this, he couldn't help but widen his eyes, and said incredulously.

Fu Bo, Mo Huai, and Mo Chui also looked at Li Zexuan in surprise at this time, they probably felt that Li Zexuan had accidentally said something wrong just now!

Li Zexuan nodded and said, "Yes!" That's right! It is to renovate the ditch with cement! First, this kind of cement ditch can reduce the loss in the process of water flow, and secondly, compared with the previous mud ditch, the cement ditch is more convenient to maintain, and does not need to be dredged every year, which saves manpower and material resources, compared with the consumption of cement, it can be said that it is too cost-effective~! ”

Yan Shaoning nodded thoughtfully and said, "That's the truth, but such a luxurious method can only be used by Lantian County~!" ”

The construction of water canals in other places is just to hire some people to make some efforts, but it is not like Li Zexuan, who has to pay both wages and cement materials!

"Huh! These efforts are definitely worth it~! ”

Li Zexuan said with a smile, then looked at Fu Bo and said, "Fu Bo, you have also read this drawing, I don't know what are the process difficulties?" ”

Fauber thought for a while, then shook his head and said: "There is no difficulty, some of the techniques used in it are all ready-made in the workshop, if the old man can't even look at the drawings, then there will be nowhere to put this old face!" Don't worry, the workshop will make the waterwheel as soon as possible, and then you can test it right away! ”

Li Zexuan nodded, with the current technical level of the workshop, it was indeed not difficult to make this waterwheel, he smiled: "That's good!" Recently, it has been hard work, the drought is like fire, let's make the waterwheel earlier, and the people will be able to suffer one less day! ”

"Young Master (Mountain Chief) rest assured, we will go all out~!"

Fu Bo, Mo Huai, and Yan Shaoning all knew the severity, and solemnly hugged their fists when they heard the words.

Li Zexuan nodded, said goodbye to everyone, and left the workshop.

..................................

Out of the workshop, it is already evening, you can see the people who are still watering in the fields everywhere outside, in this era, the water conservancy project is far from being as developed as in the previous life, such a large project as the renovation of the canal, if there is no county official to preside, basically no one will ever do it, those abandoned canals, under the rain for many years, will become blocked again, it is very troublesome to clean up, basically the same as the amount of work to re-excavate a canal!

This is also one of the reasons why Li Zexuan insisted on renovating all the canals in Lantian County with cement!

"Young Master~!"

Coincidentally, not far from the workshop, I met Hu Hanyun with a bucket.

Since Han Li is in Lanzhou as a "landlord", Hu Hanyun has become the new Li Zheng of Hanjiazhuang, Lao Hu is a man of great affection, when the world was in turmoil, he took his daughter-in-law and children to flee to Hanjiazhuang, many Zhuang households have helped him, and now he has become the Li Zheng of Hanjiazhuang, he is even more conscientious, he does not dare to slack off for a day, Zhuangzi on that family encounters something, he is always the first to hurry up to solve it, Hanjiazhuang's Zhuang farmers on Hu Hanyun's wind comments, that is naturally not to say.

"Uncle Hu, did you just come back from watering?"

Li Zexuan asked with a smile.

Hu Hanyun wiped his sweat and grinned: "It's not!" Recently, the weather has been dry, and the nutrient bowl in the ground has just been planted, if you don't water some water, it is estimated that the white stacks will not survive even if they sprout! It's a precious thing! ”

Not only Lao Hu, the people of Lantian County have been busy "watering the flowers" recently, watering the white stacked flowers that have just been planted in the ground, this thing was bought by Li Zexuan at a high price, no one does not pay attention to it, it can be said that the white stacked flowers of this acre of land are more expensive than all the crops in each of their households, if they can get a good harvest, it is basically a year to eat and drink without worry!

Li Zexuan knew it in his heart, he thought about it, and said: "Uncle Hu, you tell the villagers in a while, and you will say that the ditches in our county will be dredged soon, and then you won't have to go all the way to carry water to water the ground!" ”

Hu Hanyun's eyes widened in surprise and said, "Young Master, what you said is true?" The county wants to help us unblock the ditch? ”

Li Zexuan smiled: "Naturally, it's all true!" In a few days, the county government will organize the people to start construction, and if the farmers have leisure, they will go to help, not to mention the progress of the work, but also get a salary! ”

Lao Hu hurriedly waved his hand and said, "Eh! Young master, what kind of wages are not paid? Both horizontal and vertical are to help us build our own ditches, and we should do our best! You can rest assured, when the time comes, you don't have to ask, as long as the dealers have the motivation to make, they will go over to help, we don't have anything else, but this arm still has the strength! ”

In ancient times, the people were simple, as long as the people in the government were willing to organize everyone to dredge the ditch together, they were willing to do it even if they didn't need to be paid, besides, the ordinary people in ancient times were generally forced to do it, and doing these things could not only reduce part of the labor, but also help their own farmland irrigation, why not do it?

Li Zexuan smiled and said: "Uncle Hu, there will be some of this salary, but it won't be too much, after all, the amount of money that can be advanced in the county government is also limited, but at least it will take care of the food. ”

In ancient times, thirteen or fourteen years old was considered an adult, and at this time, the children of ordinary people generally did not have fat people, because they could not eat a lot of fish and meat at every meal, so it was a good idea to let them take advantage of the opportunity of the helper to eat a few more days!

Hu Hanyun grinned and said, "Make! Make! This makes it! Those little bastards, they squat in the Zhuangzi every day and don't do anything serious, and letting them help is just to hone and hone their temperament! ”

Li Zexuan smiled undeniably, chatted with Hu Hanyun for a few more words, and then left.

It was getting late today, so he didn't plan to go to the county seat, and went back to Yunshan directly.

………………………………

Early the next morning, after Li Zexuan finished practicing and eating breakfast, he directly hit his horse and went down the mountain towards the county seat of Lantian County.

In order to prepare for the big wedding, Li Zexuan gave him a few days of vacation, so he didn't come with him today, and now Li Zexuan is followed by the two brothers Liu Feng and Liu Yun!

Li Zexuan is now a marquis of ten thousand households, and he has to be followed by guards when he goes out, not to mention for safety or anything, no matter what, it's also a platoon!

It is said that these two brothers are from the forbidden army, and they were originally sent by Li Er to help Li Zexuan find minerals and serve as guards by the way, but Li Zexuan has been busy with vanadium mines, dams and drought fighting recently, and he doesn't know what mines he should mine next, so he didn't arrange a prospecting task for the two of them, so these two temporarily became guards.

Entering the county seat of Lantian County, Li Zexuan went directly towards the county office, and when passing by another street next to the county office, Li Zexuan inadvertently glanced at a luxurious mansion with Yong'an Hou Mansion written on it, he couldn't help but be stunned, and then knew in his heart that this should be his new mansion in Lantian County!

It's a shame to say that he heard He County's order say that the new mansion was built, but he hasn't had time to go in and take a look until now, and then the decoration and furniture procurement in the new mansion are all handled by his father and mother, and he has paid for it, so it can be said that he has not made a little contribution to this new mansion!

However, judging from the appearance alone, this new mansion is much more magnificent than the mansion in Chang'an, at least the two stone lions at the door are very rich, Li Zexuan likes it very much!

Yunshan Villa is a small building in modern style, suitable for a short stay and vacation, and this mansion in Lantian County can be regarded as a formal Hou Mansion, which has symbolic significance, symbolizing that the owner of Lantian County lives here, so the architectural style of this mansion is an authentic Tang style building.

After living in Yunshan Villa for more than half a year, it may not be bad if you change back to a Tang Dynasty-style mansion!

Li Zexuan thought in his heart, after a while from the county government to explain the matter, he had to go to the new house to see, he didn't aspire to be a sage like Dayu, he couldn't do such a thing as passing through the door three times without entering!

In other words, if this luxury mansion is left in modern times, it will have to be sold for billions, right? But Li Zexuan only spent less than 10,000 yuan to build such a luxurious mansion, which feels a little dreamy when you think about it!

Even so, it is estimated that some people may say that he is extravagant, but for Li Zexuan, he has made so much money, can't he enjoy it and let his family live better? Besides, he is not the kind of person who is unkind to the rich, he has paid out of his own pocket and led the people to get rich, he himself can't count the examples!

"Master Hou, do you want to go in and sit down? The old man and the old lady should be up now! ”

Liu Feng saw Li Zexuan looking at the mansion in front of him for a long time, so he suggested loudly.

Li Zexuan came back to his senses, shook his head and said, "It's important to get down to business, let's go to the county government first!" ”

After that, he urged Da Bai and walked towards the county office.

When he arrived at the county office, Li Zexuan didn't let people pass it on, and came directly to the back office, He County Ling happened to be in the back office at this time to review the official documents, and when he saw Li Zexuan suddenly coming, he was taken aback, and said in his heart Could it be that he has done something bad recently, so Li Zexuan will personally come to the door to ask for the crime?

Pressing the doubts in his heart, He Xianling hurriedly greeted him and said, "Xiaguan has seen Master Hou!" ”

"Hmm~!"

Li Zexuan nodded and walked into the hall, and then he asked, "He County Order, the weather has been dry recently, and the crops in many fields are showing wilting, do you know?" ”

He Xianling was shocked in his heart, and then he understood Li Zexuan's intention, he hurriedly arched his hand and said: "Back to Hou Ye, the lower official has already known about this matter, and two days ago, the lower official has already discussed the solution with the county Cheng and the main book of the Yali, we decided to gather the people of all villages, dredge the ditch, and then divert water from the dam built by Hou Ye, Xia Guan originally planned to go to Hou Ye and you to discuss this matter today, but I didn't expect Hou Ye to come to the county government so soon!" ”
