Dipped the carving knife and some water, Liu Yi looked at the long wooden stick in front of him, but didn't know how to start for a while. After a long time, he was helpless. He wanted to make a curved plow, but there was no prototype. He was a child who grew up in the city. Even when he followed his parents back to the village to visit relatives, he often saw some hoes, rakes and other farm tools. For him, it seemed to be something from another dimension.

I originally thought that it would be not difficult to make improvements based on the straight plow, but now when I really want to do it, I find that some people don’t know what to do.

In terms of purpose, the curved plow should be more convenient on the basis of the straight plow, and it is actually agile. The function of the straight plow is actually good, but it is not convenient to operate and is too bulky to be controlled by a person. It usually requires animal power to pull it, and it is difficult to turn.

In this case, as a civilization that can last for thousands of years after the straight plow, it will still be used in modern times. It will definitely be more flexible, able to operate flexibly, rotate freely, and not too laborious. Otherwise, what would it be made?

Liu Yi came up with several solutions, and it was indeed flexible to operate, but it was not suitable for promotion. The internal mechanism was too complex and easily worn. The most important thing was that the cost was higher than that of the straight plow, which did not meet the promotion requirements. So Liu Yi has been thinking about this issue these days.

The battle of Chibi is a foregone conclusion. Next, we need to consider not war, but rest and recuperation. In the farming era, food is also an important criterion that determines the upper limit of the population. The land of Jingxiang and Yizhou is not serious yet. These two states are originally grain-producing places, but what Liu Yi thought was to allow the population of these two places to grow explosively. In this way, with the current farming standards, the upper limit is actually limited.

If the industry is to rise, the most important prerequisite is to improve agriculture and a large amount of surplus labor will be qualified to promote the development of industry. Otherwise, you will not be able to eat enough. What is the use of developing industry alone?

The Han Dynasty was not as backward as expected. During the Western Han Dynasty, the people had already begun to know how to use manure to promote crop production and increase grain production. In this regard, Liu Yi might not have much effect if he wanted to study it forward. He could only work hard on tools.

Curved plows and seedling machines now have prototypes. It cannot be too complicated to improve on this basis. Moreover, things must be able to be used. The efficiency must be higher than the original straight plows and carts.

Finally, several grooves were pulled and the components were assembled, Liu Yi unconsciously set up a mechanism and finally threw the semi-finished product aside.

It’s not that it can’t be done, what it wants is practical and widely used, and the operation cannot be too complicated. In this way, the mechanism and complex mechanism cannot be used on it. It must be like a hoe, and ordinary craftsmen and even the people can do it by themselves. This is not the time to show their abilities.

"What are Bo Yuan doing these days?" Liu Bei came to Liu Yi, looked at the unassembled parts on the ground curiously, and said in confusion.

"A new plow." Liu Yi did not hide it, and said his thoughts: "After this battle, if the emperor could obtain the four counties of Jingnan, it would be considered a place to establish a foothold. The four counties of Jingnan were sparsely populated and were not enough to be a foundation. However, in Yi's view, these four counties have great potential. I hope to make a more convenient plow so that the people can reproduce and survive better without being forced by hunger and cold. It's a pity..."

Liu Bei glanced at the messy parts and semi-finished products on the ground and comforted him: "It is a good thing for Bo Yuan to be able to care about the world, but there is no need to rush for such a thing."

In the world, people's livelihood is very important, but at this time, Liu Bei was more concerned about military capabilities.

"Uncle I don't understand. If this plow can be completed, it will be calculated based on the population below today. The people will no longer have to be confused about hunger and cold, and can support more people." Liu Yi shook his head.

If we look at it from the map, whether it is Jiangdong or later Shu Han, in fact, in terms of area, it is not much smaller than Cao Cao's territory, but why do we say that Cao Cao has two parts of the world?

It is because the most densely populated prefectures and counties in the Han Dynasty were basically under the rule of Cao Cao. Although Yanzhou is not large, it has the largest population. In the entire history of China, the political culture basically radiated around the Central Plains, and exported southward on both sides of the Yellow River. The population distribution also follows this rule.

Liu Yi is not thinking about how to defeat Cao Cao now, but how to develop the population and use his own abilities to develop the south. Although the population is not as good as that, in terms of resources, this place is actually not inferior to Cao Cao at all. It’s just that no one is willing to spend the effort to develop it.

Perhaps from the current situation, Zhuge Liang's Longzhong is right or wrong, but from the perspective of the entire nation, Longzhong is not necessarily a good thing. It can only be said that the perspectives of the station are different, and what you see is also different.

For Liu Yi, the Five Barbarians invaded China was a thorn. He did not want such a thing to happen, so after stability, he first thought about how to develop people's livelihood rather than war.

But Liu Bei obviously did not consider this issue, or in other words, not many people would consider this issue today. After all, even if the world is falling apart, the Hu people outside the Great Wall did not have much deterrent power to the Han people, and they were not even regarded as threats. So when Liu Yi was studying this thing, Liu Bei could not be disappointed, but he did not have too much expectations. At present, he hoped that Liu Yi could make some powerful war weapon to help him conquer cities and territory. As for people's livelihood, it has been like this for thousands of years. It cannot be said that he did not pay much attention to it, but he just felt that there would not be too much development.

Liu Yi thought about it, found a piece of paper, put it on the table he made, and picked up the pen to outline it. He had already made the curved plow, but the mechanism was too complicated, so he was going to streamline those complex mechanisms step by step to the point where ordinary craftsmen could do it.

"Is this... Cai Hou's paper?" Liu Bei looked at the paper that Liu Yi spread on the table with some curiosity and asked casually.

Caihou paper is not too popular. Although it is convenient, it is easy to damage and is not as easy to store as bamboo slips.

"Well, I have recently studied Cai Hou Paper. Yi has some ideas. If it can be successful, it will help the emperor to win the hearts of the poor people in the world in the future." Liu Yi nodded. In fact, since there is paper, there is already the conditions for printing. There is no need to worry about movable type printing, and there is no need to print, but there is no problem with rubbing. The technical difficulty is not high, but the requirements for ink are high.

But Liu Yi didn't know how much impact it would have and whether he would be implicated. He was planning to discuss with Zhuge Liang after he had been busy with this period of time and stabilized. This is an innovation that subverts the monopoly of knowledge. If he doesn't take action, he will be quick, accurate and ruthless. Therefore, the timing is very important.

Liu Yi couldn't see this opportunity, so he wanted to ask Zhuge Liang to take a look and try to eliminate the factors that were unfavorable to him.

"Oh?" Liu Bei's eyes lit up when he heard this. He was very interested: "Can Bo Yuan explain it in detail?"

"What's the problem with these words?" Liu Yi searched through the ruins next to him for a long time, and took out a few words and handed them to Liu Bei. This was his test piece, and he was rubbing it out of a piece of rubbing he made.

As a result, Liu Bei looked at Liu Yi in confusion and looked down. His handwriting was neat, but it was just a regular one. At least Liu Yi was not outstanding in calligraphy.

"The Analects of Confucius?" Liu Bei looked up and looked at Liu Yi in confusion.

"Uncle Emperor looked down." Liu Yi nodded: "The content is not important."

"Oh." Liu Bei lowered his head and continued to read. The second page was still the Analects of Confucius. Liu Bei glanced at Liu Yi, a little confused. He continued to turn back, but he was still the Analects of Confucius.

My brows gradually frowned. What does it mean to show yourself the Analects of Confucius?

The content is not important? Liu Bei looked it over again and didn't see anything. It was no different except that the handwriting became increasingly lighter, and even every word seemed to be exactly the same. How could this... be possible?

Liu Bei suddenly looked up, looked at Liu Yi, and said with some uncertainty: "Bo Yuan, why are the words on these papers exactly the same?"

This is no longer a question of whether the handwriting is written by the same person, but in addition to the different ink color and thickness, the shape of the characters and the distance between characters are almost the same. No matter how powerful the calligrapher is, there will always be nuances in writing the same thing.

Liu Yi did not answer, but searched for a bunch of semi-finished products for a while, found a black-painted wooden board covered with ink, and found another piece of paper, quickly applied the board with a brush, spread the paper on the board, then took it down, and handed it to Liu Bei: "Uncle Emperor, take a look at this one again."

Liu Bei took it and compared it carefully. It was exactly the same as the previous few pictures. This time, Liu Bei knew how Liu Yi made it, and hesitated and said a little hesitantly: "What's the use of this?"

"I can't explain it clearly." Liu Yi shook his head helplessly and said, "I'll discuss this matter when Kong Ming comes back. Although the rubbing has been made, if the rubbing is printed, the ink will be easy to dry and it will be impossible to print it again after printing a few pages. We have to find something more suitable to replace the ink. Except for Kong Ming, the emperor must remember not to mention it to anyone, which has a lot to do with it."

Liu Bei could not get around for a moment and nodded silently. Although he didn't figure it out, he seemed to understand it. Seeing that Liu Yi's expression was unprecedentedly serious, he solemnly put the pages into his arms and said to Liu Yi: "Kong Ming just heard the news that before Jiazi day, he would send the hundred fast boats to Chaisang."

"It's ready, you can send it there anytime." Liu Yi's eyes lit up when he heard this. On the Jiazi day, it was November 20th, and there were only a dozen days left before now. It seemed that the Battle of Red Cliffs had come to an end. He said to Liu Bei: "Then Kong Ming should also ask the emperor to prepare for pursuing Cao's army?"

"Not bad." Liu Bei nodded.

"In my opinion, pursuing Cao Cao's defeated army is important, but the lord of the Jingxiang soldiers in the water camp should also surrender as soon as possible, at least give them one that we are willing to accept. Once Cao's army is defeated, if these Jingxiang soldiers and horses want to surrender, they will first choose our army!" Liu Yi said with a smile.

"Don't worry, Bo Yuan, Kong Ming said the same thing." Liu Bei smiled.

"Uncle Emperor remembers that it was the emperor who surrendered the Jingxiang Navy, not the young master Liu Qi." Liu Yi looked at Liu Bei and said seriously.

When Liu Bei heard this, he nodded silently, knowing what this means.
