"Irrigate thousands of hectares of fertile land in two days? This must be the trick of the legendary warriors to turn stones into gold. ”

"Pingyang Hou told an interesting story, just like the goddess of Kunlun Mountain, the immortal on Penglai Island, which is very interesting."

"Maybe Pingyang Hou really has hope of creating such a thing, but this water-powered wheel that is magnified hundreds of times is not enough."

Many liehous began to speak one by one, implicitly criticizing Pingyang Hou's penchant for boasting and exaggerating his actions, and the young people saw these old guys talking, and they wisely chose to shut up and pretend to be stupid, these old guys were at least thirty years old, at least ten years older than their group of young people, Chen He, Guan Qiang, Zhou Zuoche and others did not dare to quarrel with them lightly.

After all, these people participated in the rebellion of the Seven Kingdoms of Wu and Chu back then, and followed their parents and even ancestors to fight against the princes and kings, not only bold but also ruthless, not like Chen He whipping Chen Chan such a trivial matter, but the ruthlessness that kills people with one hand.

Wu Yingqi suddenly sneered: "Are you talking nonsense to make us joke?" Irrigation of thousands of hectares of fertile land for five days, and only a foolish person would believe that the man who made such a thing must be insane. ”

The princes were all stunned, in terms of seniority, Wu Yingqi was the oldest in this gang, he grew up with the older generation of Gaowan Marquis Bingwu and Qinghe Marquis Wang, and he was also a man of the hour in Chang'an more than 20 years ago, even in the decline period of the liehous, he still dared to sneak around in Chang'an City behind a few big brothers.

At the beginning, the courage of that group of people was much greater than that of Chen He and Guan Qiang, not to mention the rebellion of the Seven Kingdoms of Wu and Chu, Wu Ying Qi dared to compete with the violent bushman, and the two of them fought so hard that they almost opened the head of the bushman.

Cao Shi didn't know this old guy very well, but he also knew that his qualifications were not good to provoke at will, so he shrugged indifferently: "If you don't believe it, don't believe it, we can't help it." ”

"Huh! Ying Qi should listen to the words first, maybe this waterwheel is really that magical. Xue Ze hurriedly came over to persuade peace.

His persuasion aroused the dissatisfaction in Wu Yingqi's heart, and he glared at his best friend and said: "The Marquis of Pingjian is also a high-ranking official in the court, how can you cover up the things that these children play with, you are losing the dignity of a high-ranking official of Qianshi by doing so." ”

Xue Ze was reprimanded with a gray face, and he didn't dare to be angry with Wu Ying, so he sat back helplessly and kept silent.

This trouble made others unhappy, Chen He was annoyed by Wu Yingqi's rudeness, held his throat like a woman, pinched his orchid finger and threw a flattering eye: "The Marquis of Pingjian is also a high-ranking official in the court, and he loses the dignity of a high-ranking official of Qianshi." ”

"Good for your Chen Zishi, you dare to bully me! Ask me how your father treated me in the first place, and even if you are a vertical man, you dare to insult me! Wu Ying Qi overturned the case and picked up the paint plate and threw it over, but was dodged by the agile Chen He, and the liehou on both sides hurriedly pulled the two of them, for fear that the two of them would really pick up their sleeves and fight, even if Wu Ying Qi had been fighting for a long time, he couldn't stop Chen He's brothers from beating the master indiscriminately.

The banquet was bound to go on, Cao Shi saw that everyone was unhappy and seemed to be about to make a feud, so he explained: "Speaking of which, I blame me for not explaining clearly, how is the waterwheel or seeing is believing, if you have leisure, go to the field with me to see how the irrigation is going?" ”

Chen He rubbed his hands and said excitedly: "Okay! Let's go and see if Pingyang Hou is bragging, or a certain master is stupid and brainless. ”

"Go and go, when I'm afraid of you? Hum! Wu Yingqi got up and strode out.

In the field of Nanzhuangtou, Zheng Lao rolled up his sleeves to divert water into the ditches between the ridges, controlling the amount of water gushing out of the bamboo tubes to ensure that the ridges were watered and not flooded.

Some of the children picked up hoes, and some held kettles: "Father, you must be thirsty, drink more water and rest for a while, let the children do it for you." ”

"Eh, good boy." Zheng Lao looked at his little grandsons who were sensible and filial, and his heart blossomed as if he had eaten honey.

The old man is not young but the spirit is very good, he won the title of five doctors with the merit of Ping Yingbu, the whole family can be exempted from forced labor, the three sons under the knee have bred four grandsons and five granddaughters, the family is prosperous and does not worry about eating and drinking, life is rich, and the biggest hobby every day is to do something in the ridges of the field to play time.

Sitting next to the ridge for a while, the old man couldn't help but stand up and walk around to inspect the ridge, looking at his posture as if the general was reviewing the ranks of soldiers, with his chest raised and his expression very proud.

Raising his eyes, he swept over a group of people in the distance and walked this way, his eyes were not good when he was old, and he didn't react until he looked closer: "Ouch! Why are you here? ”

Cao Shi said with a smile: "Elder Zheng, let me come to see you and the villagers of Nanzhuang, how are you doing today's Shangsi Festival?" ”

"It's a good life, I woke up my three boys as soon as it was dawn, and asked them to take their families to the Wei River to wash and come back, so as to save people and trouble that shouldn't be caused." Zheng Lao chattered about it, it was rare for an old man in his seventies to still speak clearly, and he was very happy to see Cao Shi coming, and praised him as a good prince in charge, much stronger than the messy princes in Chang'an City.

The princes were inadvertently scolded by an old man, and Xue Ze coughed a few times: "Can the old man tell us, what is the purpose of the wooden shelves you have erected on the ridges?" ”

Zheng Lao glanced at him a few times, and now they were dressed gorgeously and behaved arrogantly, and it was estimated that it was a rich man in Chang'an City who came to talk to the prince about the sale of waterwheels, so he enthusiastically introduced: "Have you seen those waterwheels in the north?" Don't think that the big guy is slow, that thing is not small, the bucket of five buckets is pulled up one by one and poured into the bamboo tube on the wooden shelf, the river water flows down the bamboo tube to our side, there is a thin bamboo pipe for each dozens of steps to lead the water down, we use the water here to irrigate the ridges, my grandchildren are watching the irrigation, you go to see it. ”

The princes unconsciously followed the old man down the field, the cleanliness of the princes saw the new shoes rubbed with mud, depressed closed their eyes full of unwillingness, a few children in the field some weeding, some watched a bamboo pipe slowly irrigated, the clear water poured into the mud pit next to the ridge and flowed along the simple ditch to the other end of the ridge.

In less than a moment a ditch was filled, and the child turned the knob on the bamboo pipe, and the next moment the water in the bamboo pipe disappeared, and the child took out a cover-like thing to cover it, and tied it back and forth with a rope to tie a knot, so he happily walked to the other side of the ditch with his farm tools, and there was a bamboo pipe on the other side.

The princes looked at each other in surprise: "Pingyang Hou, what kind of magical thing was just now?" ”

"This is a water pipe, a simple knob valve is installed on it, the switch and flow of the water flow are controlled, the wooden frame is buried in Qianmo and is five feet deep, the bamboo row support on the top floor is very easy to disassemble and replace, and the bamboo can be replaced in a few days, and the bamboo is cut from Nanshan to dry in the shade for half a year, and many suitable bamboo poles are cut in these villages, and it is convenient to change and does not cost money."

The nobles present are not touching the spring water, there are many people, to talk about riding archery, brave and ruthless, all are experts, or the women in the Goolan village are also the head of the road, but it is still a little difficult for them to study the principle of the waterwheel and the bamboo drain, Cao Shi is left and right to explain, the princes still listen to the clouds and mountains and fog cover as if they understand or not.

It wasn't until Zheng Lao came over and said with a smile: "This is a canal in the air, our prince is ingenious, and he thought of a good way to irrigate without digging a canal, and he also gave a nice name to the suspended waterway, and the fields watered in one day and one night are hundreds of times that of carrying water on his shoulders in the past, and it took only four days to water the 23oo hectares of fields in our Hou Mansion for seven, eight or eight minutes, and there are still two or three minutes left for this night's work." ”

The princes don't understand technology, but it doesn't mean that they are just laymen who don't know anything, and they were taken aback when they heard such an exaggerated irrigation degree, and many people's eyes suddenly changed, staring at Cao Shi as if they were seeing a rare treasure, at least they still knew the efficiency of irrigation.

The edict of the Son of Heaven said that the world is based on agriculture, and the top priority of agriculture is precisely irrigation, and the social organization relies on the small peasant economy and society on the land, and the importance of irrigation is unparalleled.
