"Little lord, this is Sailuban's hut."

On the outskirts of the western part of the city, Zhang Qing and Cai Ji each led their mounts and walked to a thatched hut. This place is the temporary residence of the Yamen to settle the refugees in cash-for-work, so as far as the eye can see, there are simple shacks and tents all around. In contrast, the thatched hut with walls and roofs in front of you is naturally particularly eye-catching.

It seems that this Sailuban is quite prestigious here. Cai Ji, who was commenting so in his heart, handed the reins to Zhang Qing, then shook his long sleeves, and said to Sailuban at the half-hidden wooden door, is Ma Bo at home? ”

However, no one in the house answered. So Cai Ji cleared his throat again and reported to himself that the boy Donglai was too guarding Cai Ji and had something to ask. ”

This time, there was finally some movement in the hut. In a short time, the half-hidden wooden door was opened, and out of the hut came an old man five feet long and with gray and unkempt hair. But after seeing this old man looking Cai Ji up and down, he opened his mouth and showed a mouth full of yellow teeth and asked, "You are our little Cai Fujun of Donglai?" ”

"Exactly the boy." Cai Ji respectfully saluted the old man. Although Cai Ji's identity is Taishou, the identity of the old carpenter in front of him is just a civilian. But as long as the old carpenter is not a slave of the Cai family, then he is Cai Ji's elder. In the two Han Dynasty who rule the world with filial piety, even if Cai Ji's status is high at the moment, he has to treat the old carpenter with courtesy. Otherwise, it will be regarded as disrespectful, and spreading it will damage Cai Ji's reputation.

Therefore, in front of Cai Ji at this time, Sailuban not only did not have the slightest intention of flattering, but asked with a big grin, "The old man is Ma Ju, known as Sailuban." What's the matter with your baby looking for an old man? ”

"The boy is here today to ask Ma Bo to make a few utensils?" Cai Ji asked politely.

When Sailuban heard that Cai Ji wanted him to build a mechanism, he couldn't help but glance at her contemptuously and asked, "Do you want this baby to let the old man build a house for you?" Or a doll? ”

"Definitely. The kid brought his own sample drawings. But I don't know if Maber can make it? Cai Ji deliberately provoked.

Sure enough, Sailuban was so excited by Cai Ji, and immediately raised his eyebrows and said proudly, even if there is no sample drawing, as long as you can explain it clearly, the old man can also create the utensils you need. ”

Cai Ji saw that Sailuban's tone was so loud, and he couldn't help but secretly think that it was a mule or a man, and he had to pull it out and take a look. So she immediately straightened up and smiled at Sailuban, "Can you come into the house and talk in detail?" ”

Seeing that Cai Ji didn't look like he was joking, Sailuban nodded and led the two into the house. But Cai Ji stepped into the house with one foot, and was immediately vomited by a sour smell. However, she still has a little bit of concentration, so on the surface she only frowned. But even so, Cai Ji's small change in expression was still seen by Sailuban. So much so that the old man immediately sneered and said that in exchange for two meals, the old man's apprentices have to cry from chickens to ghosts every day, and the smell is inevitably stinking, and I ask the prince to forgive me. ”

was reminded by Sailuban, Cai Ji turned out that there were still three barefoot men lying in the hut. From their tired sleeping faces, it was clear that what Seruban said was true. Guan Tong and others have indeed squeezed these refugees enough. And Zhang Qing on the side saw that Sailuban was relying on his old man and repeatedly ridiculed his little master, so he wanted to go up and reason with him. But he didn't want to be stopped by Cai Ji's eyes before he could speak. For such a result, Cai Ji was already mentally prepared when he was in Changguang County. Fortunately, most of the people in this era are grateful for their food. It's rare to see a "Diao Min" like Sailuban who doesn't know what to do. Therefore, Cai Ji at this time only smiled bitterly at him, "Extraordinary times, extraordinary means, please forgive Ma Bo." ”

Sailuban saw that although Cai Ji was young, he was not small. couldn't help but put away his previous contempt, stretched out his hand to Cai Ji and said, "What about the picture? ”

Seeing that Sailuban was no longer entangled in the matter of cash-for-work, Cai Ji hurriedly took out a sample drawing from his sleeve and handed it to Sailuban Dao Mabo, please take a look. ”

Sailuban took the white cloth in Cai Ji's hand and shook it open, and his expression immediately changed from initial disapproval to solemnity. I saw that after carefully figuring out the pattern, he looked up and asked, "Is this painting a rollover?" ”

"Nope. When Ji was in Beijing, he saw farmers use this kind of overturned cart to divert water to irrigate canals. Ji still remembers that the body of this overturned car is made of wooden planks to make a long groove, and this groove is two zhang long, and the width is not a certain length, some are four inches, some are seven inches, and the height is about one foot. There is a pavement slab in this long groove, and the width of this pavement slab is about the same as the width of the long groove, but the length is one foot shorter than the two ends of the long groove, and the place shorter than the long groove is used to place the large and small axles. In addition, the upper and lower circumferences of the pavement slabs are tied with keel plates. The big shaft is placed on the shore, and the two sides of the big shaft are respectively connected with the crutch with four small wooden sticks in the form of handles, as long as the person leans on the shelf, stepping on the small stick, will step on the crutch, and stepping on the crutch will drive the keel plate at the same time, then the keel board will rotate around the pavement board, so as to scrape the water ashore. Cai Ji nodded and introduced. And the reason why she said it so clearly was because the inventor of the overturned car was Bi Lan, a eunuch inventor during the period of Emperor Ling of the Han Dynasty.

According to the official documents of the Taishou Mansion, in the third year of Zhongping (186 AD), Bi Lan made a dumped car to take river water to sprinkle the road, and attached relevant accounts. It can be seen that Emperor Ling and others did think of some ways to fight drought at that time. However, it was not until the reign of Emperor Wei Ming that it was improved by the great inventor Ma Jun and promoted to the whole country. Of course, there are reasons why it is difficult to promote new technologies due to years of war. However, the identity of Bi Lan's ten permanent servants may also be one of the factors that overturned the car will not be seen for a long time. But Cai Ji wouldn't do such a stupid thing about political decision-making technology. According to historical accounts, the drought and locust plague in the Central Plains will last for several years. Improving irrigation technology is an effective measure to ensure or even increase food production. Therefore, as soon as Cai Ji came up, he took the overturn as his opening remarks.

Sailuban is a carpenter, so naturally he will not care whether the inventor of the overturned car is the ten permanent servants who bring disaster to the country and the people. So this time, he took the sample picture to change his previous arrogant attitude, and instead asked Cai Ji respectfully in a tone whether Daofujun wanted the old man and others to build a car for the government? ”

"Hmm. Ji Zheng has this plan. However, East Ledo is mountainous and sparsely populated, so it is not enough to overturn the car. It is also necessary to build a waterwheel that can carry water to a higher place without the need for manpower and animal power. Cai Ji said as he found an open space and sat down. It's tiring to do this and stand up and discuss technical issues with people.

At this time, Sailuban's impression of Cai Ji had changed greatly, and he no longer regarded her as an ordinary official eunuch, but sincerely regarded her as a parent official. Therefore, seeing that Xiao Fujun was about to sit on the mud floor in a bright body, he hurriedly stepped forward and handed over a straw mat, and said embarrassedly that Fujun Mo had soiled his clothes. ”

"It's okay," Cai Ji smiled casually, "Ji is still worried about whether it will affect the rest of the three big brothers." ”

"The farmer's baby skin is real. Even if it thunders outside, it sleeps inside. Sailuban also sat cross-legged as he spoke, and paved the pattern to the ground, "The king of the palace said in front of him that it doesn't take manpower and animal power, so don't you want to build wooden oxen?" ”

As soon as Cai Ji heard Sailuban mention the wooden cow, he immediately came to his senses and hurriedly asked? Is there really a wooden cow in this world that can move without food? Will Ma Bo be made? ”

How do you know that Sailuban blushed, shook his head and said this...... The old man has only heard people talk about it, and he has seen real things, let alone make them. ”

Cai Ji was somewhat disappointed when he heard Sailuban say this. However, she thought about it again, and thought that the moving wooden ox and flowing horse were after all legendary things that Yan zhòng violated the law of conservation of energy. Its true face will wait until you meet Zhuge Liang and Huang Shuo and his wife in the future to get a glimpse of it. What Cai Ji has to do now is to plagiarize a famous invention that Zhuge Liang has passed down to future generations - the Kong Ming car. Thinking of this, Cai Ji immediately took out a pattern from his sleeve as if he was doing a trick, and said, It doesn't matter if he can't make a wooden cow. Ji has a diagram that can build a waterwheel without human or animal effort. ”

"Oh? This watermill does not cost manpower? Sailuban asked, stretching his neck.

"Yes. Ma Bo, please see, this car has a wheel on the top and bottom, the lower wheel is half submerged in water, and there is a wheel belt between the two wheels, and the wheel belt is equipped with many bamboo tubes with a length of rulers. The water hits the water wheel below and rotates, and the bamboo tube is soaked with water, and the river water is carried to a high place from the bottom up and poured out. Cai Ji explained, pointing to the pattern.

In fact, the waterwheel drawn by Cai Ji is more complex than the Kongming car invented by Zhuge Liang in the future, and its structure and principle are closer to the cylinder car of the Sui and Tang dynasties. Of course, it is much simpler than the famous Yellow River waterwheel in later generations, and it is also a lot smaller. After all, what Cai Ji saw at the beginning was a small waterwheel in the farmhouse to attract tourists.

No, as soon as Cai Ji's words fell, Sailuban had already seen the defects of the cylinder car. I saw him touch the messy stubble, pointed to the pattern and said that according to this method, this car does not need manpower and animal power. However, it must be located in a place where the water is turbulent before it can be rotated to lift water. ”

"Is there a solution to it?" Cai Ji asked. To be honest, she'll have a rough picture. As for how to make zuò and how to set it up, Cai Ji really doesn't know anything. That's why she needs to turn to professionals like Seluban to perfect the waterwheel.

"It doesn't matter." After carefully comparing the two drawings, Sailuban said confidently, "You can combine the two cars into one, so that they can use both water power and manpower." ”

"Then there's Raumber to improve the waterwheel." Cai Ji said that, he stood up and made a deep snort at Sailuban.

The flattered Sailuban immediately got up and returned to the Taoist Mansion to rest assured, and the matter was on the old man. ”

Cai Ji saw Sai Luban patting his chest and making a promise, and smiled happily and said that it was so good. However, can Ma Bo first make two small waterwheels for Ji according to the pattern, as for the bonsai, as long as the water is flushed, it can be automatically turned. ”

"Fu Jun wants to see if these two waterwheels can really lift water?" Sailuban shook his head and said, "Don't hide it from the prince, bonsai is different from the real thing. The mechanism that can be moved in the bonsai may not be easy to use when it is bigger. ”

Marber had a point. However, Ji made this bonsai not for his own play, but for other purposes. After that, Cai Ji turned around and motioned to Zhang Qing behind him to take out the money to Sailuban, and then, "Ma Bo, this is the deposit for bonsai, please be sure to accept it." ”

When Sailuban saw that Zhang Qing wanted to give him money, his old face immediately fell. But when he pushed his hand, he refused, saying that the old man couldn't ask for this money. The prince of the house built a waterwheel for the people of Donglai, how could the old man collect this money. If the prince insists on the old man, he will turn his face. ”

After some contact just now, Cai Ji also knew about Isai Luban's stubborn temper, and he might really think that giving money was insulting him. So at this time, Cai Ji immediately asked Zhang Qing to put away the money. And she bowed down to Sailuban again to thank Daoji, who thanked Ma Bo Gaoyi for the people of Donglai. ”

Seeing that Cai Ji no longer insisted, Sailuban stroked his beard and laughed and said that Fujun can come to get bonsai tomorrow. ”

With Sai Luban's assurance, Cai Ji naturally got up and said goodbye to Zhang Qing with confidence. On the way back to the house, Zhang Qing recalled the previous confrontation between Cai Ji and Sailuban in the thatched hut, and couldn't help but sigh with emotion. Even a tricky person like Sailuban can convince. ”

"Brother Zhang's words are wrong. Ma Bo is a knife-mouthed tofu-hearted man. Moreover, all the things he ridiculed were true. As a Taishou, I was blamed for my poor disaster relief, so why not. Cai Ji shook his head and said.

Zhang Qing saw that Cai Ji had taken everything on himself, and hurriedly defended him by saying that the little lord had only set a disaster relief plan at the beginning, and as for how to implement it, it was all the business of Guan Tong, Duan Kui, Huang Zhen and others. Why should the little lord take the sins of others? ”

"That's because Ji is the Taishou of Donglai County, and Guan Tong, Duan Kui, Huang Zhen and others are all subordinates under Ji's name. As a superior, you must be responsible. Blindly distancing oneself from the relationship will only give the world the impression of embarrassment. As for what is right and which is wrong, the auspicious world has its own public opinion. Cai Ji said proudly.

"The little lord is right. It's short-sighted. Zhang Qingshen nodded in agreement.

"As the saying goes, in his position, seek his position. Brother Zhang, as Ji's general, naturally maintains Ji's lord everywhere, and there is no short-sightedness. After appreciating Zhang Qing's loyalty, Cai Ji changed the topic again, but Ma Bo was so old-fashioned. Ji can't let it work in vain. ”

"The little lord wants to hire Sai Luban with a lot of money?" Zhang Qing asked.

"It's not just Seluban, it's the artisans here. To be more precise, Ji wants to give them a windfall. Cai Ji said confidently.

"Windfall?" Zhang Qing asked puzzled. In his opinion, if Cai Ji really wants to promote the waterwheel he just mentioned in the whole territory of Donglai, it will only cost money, where will there be a windfall.

But Cai Ji shook the horsewhip and laughed loudly. But at this moment, the secret of heaven must not be revealed! ”
