There are various bamboo slips, scrolls and messy drawings on the ground. When you first come in, you don't feel that this is a girl's room. In fact, according to Huang Yueying, she has six maids in her hometown in Jiangxia
At first, Cao Peng didn't understand why he needed so many maids. But later, based on Huang Yueying's living conditions in Hailing, Cao Peng finally understood what was wrong.
Without training, six maids might not be enough!
Huang Yueying has some big roads in life. Although she is very smart, she often gets confused. Especially when she is thinking about problems, the confusion is even worse. Basically, she will be sloppy wherever she goes. If there is no maid to follow her
, it’s really a problem.
Fortunately, Buluan and Guo Huan are both literate and smart.
With these two people following her, Huang Yueying didn't look too sloppy. However, she was tossing very hard. After so much effort, the room was already in a mess. Huang Yueying herself didn't seem to feel anything, as if she was dancing.
, bouncing around the messy room, and soon walked to the desk and sat down.
"Afu, come quickly."
Cao Peng walked over and sat down opposite Huang Yueying.
The book desk is also spread out in a mess, including white paper and charcoal pens that Cao Peng made when he was in Jiyang...
"Yueying, what are you..."
"Stop talking first and look at this."
She pushed a drawing in front of Cao Peng, her face full of expectation.
Cao Peng took it over, looked at it carefully for a moment, raised his head and asked, "What is this?"
"Rollover!"
"oh?"
Huang Yueying said excitedly: "Do you still remember the Bi Lan I told you during the day?"
"Uh... that's the Ten Permanent Attendant."
"Yes, that's him!" Huang Yueying said: "Actually, Bi Lan is not as bad as outsiders say. At least his mechanism skills are excellent, and even my father admired him very much. My father said, if not
With this skill, Bi Lan cannot even reach the position of Ten Constant Attendants. His whimsical ideas are comparable to Mo Zhai, the master of mechanism during the Warring States Period. However, this person's moral character is really inhumane."
"Wait a minute, wait a minute, what do you want to say?"
Seeing that Huang Yueying became more and more excited as she talked and the topic got further and further away, Cao Peng quickly waved his hand to stop her.
Huang Yueying smiled awkwardly and said softly: "In the third year of Zhongping (186 AD), in order to please the late emperor, Bi Lan designed a water-sprinkling device, which is a rolling cart. It is said that this tool can draw water from the river and sprinkle it on the streets.
, get twice the result with half the effort.
After my father heard about it, he asked someone to inquire about it.
But this 'overturned car' was carefully built by Bi Lan and dedicated to the late emperor. In the end, my father spent 100,000 yuan to get the model.
I remember very clearly at the time, my father was so impressed by the rollover.
He also said that Bi Lan's talent was extraordinary, but it was a pity that it was used in the wrong place... Later, my father made some small changes based on the overturned car model and used it in my family's fields. He could easily use it in the river.
The water is extracted and used to irrigate the fields.
But you also know that there is no shortage of water in Jiangxia, so it is not of much use.
Later, my father felt bored and destroyed the overturned car...but I still remember some of the general shape and structure."
"Wait a minute, wait a minute, you said my uncle once built a waterwheel?"
"It's not a waterwheel, it's a rollover!"
Cao Peng picked up the drawing again and looked at it carefully for a while.
Huang Yueying's painting skills are very outstanding, and Cao Peng felt that this waterwheel looked familiar.
Kongming car!
That's right, it's the prototype of Kong Ming's car.
I remember that in his previous life, Cao Peng visited Chengdu. He could not remember exactly which historical site it was, but he did see a waterwheel at that time.
According to the tour guide, this waterwheel was invented and improved by Zhuge Liang and promoted in Sichuan, so it is called Kongming Waterwheel.
Its shape is quite similar to the drawing in front of me.
Cao Peng couldn't help but scratch his head and laughed dumbly.
"Yueying, do you want to make a waterwheel?"
"I have already said that this is called a waterwheel... Well, the name waterwheel is quite appropriate."
Huang Yueying was very excited, with pretty pink cheeks and a bright smile, "You think, if you can make a rollover, can you solve the drought?"
"this……"
Cao Peng fell into deep thought.
China has been a country based on agriculture since ancient times. Water conservancy is the most indispensable part of agriculture, so there are endless designs for water conservancy projects.
Among them, the invention of the waterwheel is undoubtedly a huge creation that embodies the wisdom of the Chinese people.
According to legend, the earliest folk water-drawing tool was named Jumei.
"Zhuangzi - Outer Chapter - Heaven and Earth Chapter" once recorded that Confucius' student Zigong traveled to the south. When he passed Hanyin on the way, he saw an old man working hard to carry water for irrigation. So Zigong felt pity and designed a plan.
This kind of labor-saving instrument is called '槔'. The method of making it is to 'chisel wood into a machine, heavy at the back and light at the front, and pump (yin che) if the water is pumped out, it will be like a fertile soup'. That is to say, use a horizontal log
It is supported on a wooden frame, with a bucket for collecting water hung on one section and a heavy object hung on another section, similar to a lever, to save the power of collecting water.
This orange is the prototype of the waterwheel.
However, the real appearance of the waterwheel was invented by Bi Lan in the late Eastern Han Dynasty.
Later, it was modified by Zhuge Liang, and there are also records saying that it was modified by Ma Jun. But no matter who modified it, the rollover can be regarded as an official appearance.
However, because Ma Jun's environment is different from Zhuge Liang's, there are certain differences.
For example, the Kongming cart is more suitable for collecting water in the south of the Yangtze River, while the keel overturned cart is suitable for collecting water in the north...
Later, in the Tang and Song dynasties, barrel carts appeared, combined with pools and connecting barrels, which could deliver water at a low level and at a high level, which was more effective and saved manpower.
During the Yuan and Ming dynasties, waterwheels continued to develop, with gears and other components appearing, and various equipment such as water-turn overturners and ox-turn overturners were invented based on the land and terrain. However, since the Qing Dynasty, the development of waterwheels in China has stagnated.
Ex. As for the reason...
"Yueying."
"Um?"
"Actually, I think we can do better."
Huang Yueying's eyes lit up when she heard this.
"How to do it?"
Cao Peng picked up the charcoal pen and turned it around twice in his hand.
Charcoal pencils, after Huang Yueying's improvement, extract charcoal strips from charcoal, and then use a half-centimeter-thick hollow wooden strip to carry them. There is a plug inside. When the charcoal pen tip is used up, the plug can be pushed to remove it.
The charcoal strip exits the wooden strip and continues writing.
And this design is exactly the work of Huang Yueying.
Cao Peng played with it for a while and couldn't help but admire Yueying's clever mind.
He closed his eyes, pondered for a moment, and then drew a picture. However, his painting skills were definitely not as outstanding as Huang Yueying's. Fortunately, Cao Peng could explain it.
In his previous life, when he first started working, Cao Peng went to Gaolan County, Lanzhou City to escort a prisoner because of a case.
After the prisoner was handed over, his local colleagues took him to visit Gaolan and appreciate the customs and customs of Gaolan. The colleagues took Cao Peng to visit a tiger car. The tiger car is also a water wheel, also known as Lanzhou water wheel, sky wheel and other names.
Colleagues proudly introduced this crane at the time, saying that this crane was the earliest crane in China... and the person who invented this crane was Duan Xu, a Gaolan native during the Jiajing period of the Ming Dynasty.
Duan Xu was once a Jinshi scholar and was very knowledgeable and talented.
After traveling to several southern provinces as an official, after becoming an official, he consulted what he saw in the south and built a Lanzhou waterwheel, which could divert water from the Yellow River to irrigate the fields...
Its shape is different from the keel waterwheels in the south at that time, and looks like a huge ancient wheel.
The diameter of its spokes ranges from 20 meters to 10 meters, and it can lift water to a height of 15-18 meters.
When Cao Peng heard the proud introduction from his colleagues, he couldn't help but be curious about it. When he left Langao County, his local colleagues also gave him a model of a Lanzhou waterwheel, with a picture and text introduction. Later, the model,
Along with the destruction of the family, it also turned into ashes.
Cao Peng must not remember the specific data clearly.
But Cao Peng can still recall an outline of its outline and some simple structures...
He drew a simple outline diagram based on the shape of the Lanzhou waterwheel, and then explained it to Huang Yueying one by one. When he encountered a place that he couldn't remember clearly, he just blurted it out. But even so, Huang Yueying's eyes flashed.
Shining, with a hint of excitement.
"Afu, how did you come up with this?"
"Well... you also know that there is no water around Zhongyang Mountain. Sometimes I see people working hard to collect water, so I have random thoughts."
"Well, your design is better than mine."
But after Huang Yueying said it, she showed a distressed look, "It's just that this thing is very complicated and it's not easy to build it in a short time.
Moreover, such a big overturn seems to be somewhat, somewhat..."
Huang Yueying couldn't tell.
The design of the Lanzhou waterwheel was designed by Duan Xu based on the characteristics of Gaolan in the Ming Dynasty.
Lanzhou at that time was not comparable to Lanzhou during the Three Kingdoms period.
At the end of the Eastern Han Dynasty, Lanzhou was named Jincheng County. Although it was also very desolate, it had abundant water and grass and was a place where Qiang and Han people lived together. The so-called bitter cold just meant that the living conditions were not good. You must know that although Jincheng County is in Xiliang, it can be regarded as belonging to Xiliang.
Guanzhong area. It is said that the eight hundred miles of Qinchuan will bring prosperity to the world. Whoever wins Guanzhong will win the world... It was not until the end of the Tang Dynasty that Guanzhong was completely defeated, and thus entered the historical stage of competition between the north and the south. Before that, the world was competing for the throne.
, mostly the East and West compete for supremacy, and this has been the case from the Han Dynasty to the Sui and Tang Dynasties.
Cao Peng thought for a moment and said, "I'm not in a hurry to design this waterwheel right away.
The top priority is to perfect this rollover so that if there is a severe drought, it can be put into use immediately to alleviate the disaster...
Then, we can slowly improve.”
Huang Yueying thought for a while and nodded vigorously.
"I was a little too hasty!"
After she finished speaking, she picked up the drawings, looked at them again, and put them away carefully.
Then she laid out the Kongming car drawing she just drew on the desk.
"Afu, please help me see if you have any good ideas?"
At this time, Cao Peng was drunk and walking up, his eyelids trembling.
However, seeing Huang Yueying's high interest, he couldn't refuse too much. So he steeled himself and accompanied Huang Yueying to discuss the improvement of the waterwheel.
In fact, how could Cao Peng know this?
At first, Huang Yueying asked him for his opinion, but later she basically ignored Cao Peng.
Finally, Cao Peng couldn't help but feel tired and fell asleep on the desk. But when he woke up, he found that he was wearing a big robe. Huang Yueying's head rested on his lap, sleeping soundly. And placed
The drawings on the writing desk are densely written in small characters.
The sky has turned fish belly white.
Seeing the tiredness on Huang Yueying's face, Cao Peng couldn't help but feel a little distressed.
He stretched out his hand and gently ruffled Yueying's hair. He saw Yueying move a little, turned over, and fell asleep again on Cao Peng's lap.
This girl probably stayed up all night!
Cao Peng took off his robe and put it on Huang Yueying.
Then he picked up the drawings on the desk and looked at them carefully.
There was a soft knock on the door, and Bu Luan walked in.
Seeing the scene in front of her, she couldn't help but blush and almost screamed.
But he saw Cao Peng put his finger to his mouth and let out a "shush".
"The lady has not rested all night, let her sleep a little longer."
"Um."
Bu Luan blushed and nodded slightly.
"Pack all these away... Xiaoluan, remember to warm a bowl of porridge in the kitchen and let the lady eat it before setting off.
Also, don’t break these things, be sure to keep them well. Yueying has worked hard on them this night, so don’t mess with them.”
"My little maid knows."
Bu Luan gently packed away the drawings and the bamboo slips and scrolls on the ground, while secretly looking at Cao Peng and Huang Yueying from the corner of his eyes.
I saw that Yueying's face was flushed with a sweet smile.
Cao Peng, on the other hand, carefully moved the hair on her forehead, his face full of tenderness.
The young master treats Miss Yueying so well!
Buluan was confused and suddenly bumped into the bed next to him.
Cao Peng raised his head, let out a "shush", and shook his head gently towards Buluan. That look was enough to make Buluan's cheeks immediately turn red with embarrassment.
At about midnight, Cao Peng received the order and the old lady prepared to set off.
He quickly ordered his chariots and horses to prepare, then put on his armor and sat astride Zhao Yebai.
Huang Yueying didn't seem to wake up, she looked a little groggy and confused. After getting on the carriage, she took out the drawings and began to meditate again.
"Ah Fu, what's wrong with Yueying?"
Cao Nan couldn't help but asked softly.
"She is thinking about something... Sister, don't blame her."
Cao Peng explained: "Yueying is like this. Once she starts thinking about a problem, she always feels a little confused, as if nothing is important."
"This girl..." Cao Nan sighed and waved for Guo Huan to come over.
"You and Xiaoluan follow Yueying and don't let her cause trouble again."
In the morning, when Cao Peng went to change clothes, Huang Yueying was holding a drawing and was so distracted that she almost ate a piece of charcoal.
Cao Peng was quite helpless about this.
Guo Huan and Buluan could only be left to stare at Huang Yueying.
Outside Chen County City, the old lady boarded the carriage with the help of Cao Hong respectfully.
"Afu, my aunt is getting old. I need you to take care of me all the way to Xudu."
Cao Hong took Cao Peng's hand and gave serious instructions.
Seeing that no one was paying attention around him, he suddenly lowered his voice and said, "My aunt has a strong personality and doesn't like being greeted. She has a good impression of you and praised you very much yesterday. Don't act recklessly. Just do whatever you want.
, just take good care of it and don’t let her think you did it deliberately..."
Cao Hong is really nice to me!
Cao Peng bowed his hands and said goodbye to Cao Hong.
He raised his hand and shouted loudly: "Give me my order and let's go!"
