When the night fell, Li Mengxi couldn't bear it anymore. He yawned and said that the plow would be changed tomorrow, and then went back to sleep.

As for Guan Yu, Guan Yu looked at the plow left and right in the room. The curved shaft plow looked very simple, but it was such a simple thing, but it could plow the ground incredibly easily. He could not plow even two points of land during the day, and he could not get through it at all.

Guan Yu was so addicted that he couldn't sleep anyway, so he simply picked up the plow and went out.

In the middle of the night, Guan Yu called a few soldiers, then took torches and went out of the city in the dark to plow the fields.

I can't understand Guan Yu's behavior. He can become addicted to plowing.

The next day is the third day of the first lunar month.

That morning, Li Mengxi got up early and went to the city lord's palace. Guan Yu, who had frost on his beard and eyebrows, just came back carrying a plow.

Seeing Guan Yu's appearance, Li Mengxi was surprised, "General Guan, what have you done?"

Guan Yu carefully put the Quyuanli down against the wall and shook the frost off his body. Guan Yu chuckled and said, "I went to plow the land for a while."

Li Mengxi was speechless.

At this time, Li Mengxi did not know the seriousness of the matter. He mistakenly thought that Guan Yu got up early and went to plow the fields early in the morning. However, the actual situation was that Guan Yu plowed the fields enthusiastically all night and plowed more than two ridges.

Instead of plowing a large area of ​​land.

After that, it was a mediocre breakfast. The breakfast was quite sumptuous, including soy milk, broth, steamed buns, and fried eggs. It was absolutely nutritious.

While I was eating my meal, there was a noise outside. I raised my head and saw a few dusty soldiers walking through the door.

The leading soldier untied a large bag of things he was carrying on his back, put it on the ground, then clasped his fists and said, "According to Duke Xuande's order, we have specially sent several bags of ginger!"

Upon hearing this, Li Mengxi and Guan Yu quickly stood up to greet him.

Guan Yu pointed to the empty table in the room and said to several soldiers, "Sit in the room! I'm going to get some food."

Although they were just a few soldiers, they came from afar, and Guan Yu treated them as considerately as if they were guests.

Li Mengxi stepped forward and opened the ginger bag, took out a few pieces of ginger and looked at it. He looked at several soldiers who came from Zhuozhou, and he smiled happily and said, "Thank you all for traveling day and night to send so much ginger."

, it can solve the urgent need of our army!"

The few soldiers who had just sat down smiled happily when they heard this, and hurriedly said that everything was within their scope.

Li Mengxi didn't eat anymore, so he went over and chatted casually with a few soldiers. Li Mengxi asked about Zhuozhou, Liu Bei, and Zhuozhou. They chatted casually for a while. Guan Yu held a wooden tray and put some things on it.

Several large bowls of steaming broth were delivered.

Seeing this, Li Mengxi stood up and left in time. He smiled and said to a few soldiers who were half-familiar and had rarely seen each other, "Eat while it's hot. Fortunately, you came back in time. We just slaughtered a lot of animals a few days ago."

, just in time to eat meat."

Guan Yu personally came to deliver the food to the soldiers with a wooden tray. The soldiers didn't dare to argue, so they quickly came to take it.

After all the soldiers had eaten, Li Mengxi returned to his seat and continued eating.

Up to now, Li Mengxi, who was not very familiar with the ways of the world, has somewhat developed some abilities through experience.

The broth must be delicious, as you can tell by looking at the few soldiers devouring it.

Liu Bei had only returned to Zhuozhou a few days ago. Immediately, soldiers brought ginger from Zhuozhou. Although there were not many things, Liu Bei remembered the Julu people, which made Guan Yu feel warm.

Guan Yu really wanted to ask about Zhuozhou, but it was hard to ask him while he was eating, so he could only wait until after eating.

Finally, when the soldiers finished drinking the large bowl of broth, Guan Yu served another large bowl to each of them. After the soldiers finished another bowl and made sure that everyone was full, Guan Yu then asked.

Things to do in Zhuozhou.

The soldiers answered all the questions one by one, but Guan Yu didn't ask anything, because these cavalrymen answered that they had just returned to Zhuozhou the next morning when they were sent back to Julu by Liu Bei.

Zhuozhou has not been here for a day, so I don't know much about Zhuozhou's affairs in detail.

Guan Yu nodded and asked several cavalrymen, "Big brother sent you back. Did you say that after sending Jiang off, do you still want to go back and obey the order?"

The cavalry captain replied, "Never."

Guan Yu smiled and said, "Then stay in Julu. We have a lot to do here!"

What Guan Yu said came from the heart.

Speaking of which, since everyone separated and Liu Bei left, so many things have happened here, including pressure cookers, paper making, activated carbon, iron pots, delicious sweet and sour fish, white steamed buns, and altars.

, and the Quyuan plow yesterday, these things are very interesting.

——

Continuing what we left unfinished yesterday, the most important thing to do today is to optimize the structure of the curved shaft plow, finalize it, and then put it into production.

After dinner, Li Mengxi and Guan Yu went to the craftsmen camp together. After a large group of craftsmen of various types were gathered together, everyone looked at Li Mengxi.

Li Mengxi scratched his head and thought for a long time. Everyone was waiting for him quietly.

The structure of the curved shaft plow is simple and can be improved. Li Mengxi thinks there are several points. The first is the plowshare. How big is the appropriate plowshare? If it is too large, it is not only wasteful, but also eats up too much soil when plowing and is too heavy.

Reversely affects the farming speed.

If the plowshare is too small, the soil will be eaten too shallowly and the plow will be narrow, which will also affect the efficiency.

In addition to size, shape is also a consideration. Which plow head shape is the sharpest in breaking through the ground? Is it pointed, or is it a fusiform shape, which is the so-called streamlined shape, or is it an arrow shape, or is it a wing shape, with a raised prismatic shape in the middle?

.

If the soil is fluid, then Li Mengxi knows that the streamline must be longer than breaking the soil. However, the soil is both solid and not purely solid. The soil is relatively soft, so which type of plow head is the best? Li Mengxi has limited knowledge and cannot figure it out.

We can only try all possibilities.

In addition to the shape of the plow head, there is also the installation angle of the plow head, whether it is better to plow deeper into the ground or shallower, which also affects the use of the plow and is also closely related to the efficiency of plowing.

In addition to the plowshare, there is also a plowshare. The points that need to be considered for a plowshare include the size of the plowshare and the angle of the plowshare. The plowshare is a curved iron piece, so what is the curvature of the plowshare?

The curved shaft plow also has a shaft arm. How should the shaft arm be bent in the most coordinated manner? Is it a whole arc or an S-shaped arc? Also, the most troublesome part of the entire curved shaft plow is the shaft arm. Is there any?

It is possible to further simplify the shaft arm manufacturing process and further reduce costs.

In addition, the most appropriate height of the curved plow needs to be tested, and the length, height and inclination of the handrail of the curved plow also need to be tested to find the best style.

Also, which kind of wood is the best for the curved-turn plow? Anyway, willow will definitely not work. Willow is as soft as noodles and is very intolerant. Therefore, although wood is the key to the curved-turn plow, it is also necessary to make a slight selection of the wood.

Li Mengxi thought that there were as many as twenty tests, and he assigned the craftsmen a huge production and R&D improvement task. Li Mengxi said to all the craftsmen, "Anyone who can improve the Quyuan plow will be rewarded with a hundred dollars."

Go through! No limit to the top!"

A reward of a hundred guan is a heavy reward. For a long time, the rewards that the craftsmen have received are only two hundred catties of grain at most. When a heavy reward of a hundred guan hits their eyes, the craftsmen are all excited.

The craftsmen went back to work energetically. Li Mengxi looked left and right. Although he also wanted to go deeper into the improvement, Li Mengxi clearly knew that the wisdom of many people must be better than the wisdom of one person, especially when it comes to fittings such as Quyuan Li.

Craftsmen may have many fantastic ideas for agricultural production tools.

——

In the carpenter's camp, a group of craftsmen went back to work and walked back to the construction site. The excited craftsmen, stimulated by the huge reward of a hundred dollars, were gearing up. One person looked around and suggested, "This plow is easy to make, how about we

Do more and see if you can come up with ideas for changes?"

Everyone unanimously agreed and started making the Quyuan plow.

This first piece of valuable advice has come out.

There is only one prototype of the Quyuan plow, but here is the problem. If you want to improve it, there is only that one plow. You can’t squeeze in even if you try to get up close and touch it. If you say you want to improve it, but you can’t touch it, isn’t it the same as watching the flowers from the other side?

, how to improve.

Therefore, since we want to gather the wisdom of everyone, the first step is to let everyone have a curved shaft plow to toss.

This point was so important that Li Mengxi didn't even think of it. Fortunately, the craftsmanship system was perfect, and the production enthusiasm of the craftsmen was fully stimulated, and the defects were automatically made up. This shows the power of the craftsmanship system.

On the other side, at the iron-making furnace, there were a group of blacksmiths, some were burning the furnace, some were forging iron, and another group of people squatted on the ground and gathered in a pile, chattering.

The improvement of the curved shaft plow was assigned to the blacksmiths. The improvement work of the blacksmiths must be the two iron parts of the plow head and the plowshare.

The craftsmen murmured for a long time. One of them, an old blacksmith, scratched his beard and frowned and thought for a while. He looked up at the people around him and said, "Speaking of plows, I saw that there are some in our big family."

"It's like a plow," the old blacksmith said, clasping his hands together to make a triangle shape, "The plowshare is also big, as big as the washbasin. I saw them plowing the ground with a pole as thick as a tree wheel. They used eight plows at one go.

An ox, I think this plow is good, but it's just scrap metal..." The old blacksmith hesitated.

A person on the side said, "If the iron is there, it will be useless if it is broken, no matter what he does!"

In a few words, I decided to make a large plow with a tall raised bulge in the middle.

The plowshare mentioned happened to be one of several plowshares conceived by Li Mengxi.

The inspiration for Li Mengxi's conception of the plowshare structure was submarines, airplanes, bird wings, and arrowheads. The inspiration came from various high-end technologies of later generations, but none of them were down to earth.

The old blacksmith saw that a large household had a giant iron plow. It can be seen from this that the landowners who owned a large amount of land resources in ancient times had some relatively advanced production technologies.

——

For a long time after the early morning, the craftsmen were busy in full swing, while Li Mengxi went to perfect the test plan, preparing to test it in an orderly manner after all the samples were made.

Guan Yu had nothing to do to help him. Guan Yu took a piece of broken tile and sharpened the plow blade to make it smoother.

In the blink of an eye, most of the day passed. In the afternoon, Li Mengxi went to the craftsmen camp to have a look. After a long day of work, the craftsmen had made a large number of new plows.

Li Mengxi was surprised when he noticed a craftsman removing the wheel and putting it on the plow in the carpenter's camp.

Li Mengxi also saw that someone made a plow with a base that was as big as a door panel. Li Mengxi was stunned. He didn't understand why a plow looked like a plow and a rake for raking the ground.
