I have to say that there are really geniuses in this world, and Zhuge Hui is one of them. Li Rui just drew the image of the curved plow for her, and she sorted out the curved plow from three to five to two based on the rough image. This action efficiency really made Li Rui stunned.

He stood by the field and watched the farmer drive the cow and pull the plow, plowing one field after another, and the more he looked, the more melancholy the performance of the new plow was no longer different from the curved plow he remembered! Zhuge Hui just took a look at the drawing and sorted out this thing. How could he pretend to be like this in the future?

However, the main body of the plow is made of wooden after all, and it is not very satisfying in terms of durability. Li Rui stared at it for a while and saw a farmer stopping, slamming the wooden hammer and starting to repair the plow. He walked over and saw that some mortise joints were loose and they had to be knocked tightly, otherwise the plow would have to fall apart.

In addition, the plowshare is difficult to satisfy. The main body of the plowshare is also made of hardwood, and only the small section of the plow tip is iron, which looks clumsy and rough, which is a hundred thousand dry miles away from modern plowshares.

"Is this plow good?" he asked.

The old farmer smiled and showed his yellow teeth: "It's so good, so it's much more labor-saving than the long-shaft plows and straight plows that were commonly used. It's not tiring to plow a few acres of fields in one breath!"

Li Rui said: "But the plow body is made of wood, it is not very durable, right? If the plow body can be made of iron, there is no need to stop and repair it from time to time. And the plow is not strong enough, if it can be replaced with pig iron..."

The old farmer waved his hands repeatedly: "That won't be enough, iron is so expensive! Not to mention whether it can be used as a plow body to help it. Even if it can be made, we can't afford it!"

Li Rui glanced at his torn clothes, sighed, and did not continue chatting with him, silently retreated back to Tianbian.

Zhuge Hui saw that he was in a bad mood and came over and asked, "What's wrong?"

Li Rui said: "The people are so poor that even if they can make some good things, they can't afford them!"

Zhuge Hui deeply agreed: "Yes, the people are too poor and too miserable... Of course, they probably don't think so."

Li Rui was stunned: "How do you say this?"

Zhuge Hui pointed to the farmers who were humming songs and ploughing hard: "In their opinion, it is a great happiness to plow the fields in the fields when the world collapses. "

Li Rui silently said, "It shouldn't be like this. They should live a better life with such hard work!"

Zhuge Hui said: "That is your responsibility, Lord County Master."

Li Rui nodded and suddenly said: "That thirsty black is easy to use, but it is still too troublesome to make it. As long as there is a bamboo tube that is not sealed, as long as there is a crack or an insect eye, all previous efforts may be wasted. Therefore, it is not a good assistant to resist drought. To overcome drought, you must have a tool. It is a more efficient and simpler and more reliable water withdrawal tool."

Zhuge Hui immediately became interested: "How about the keel chariot? It can draw water from a low point to a high point. It is used in large quantities when Cao Wei was busy farming, and the effect is pretty good."

The keel she mentioned was invented at the end of the Han Dynasty. The Eastern Han Dynasty was very unlucky to catch up with the small ice river climate. In the long period of nearly two hundred years of Eastern Han Dynasty, natural disasters never stopped. In those frequent natural disasters, droughts were fatal. Although earthquakes were terrible, there were no high-rise buildings in this era. Many people still lived in thatched huts, and earthquake damage was limited. Floods were also terrible, but the floods were riotous last month. Even if the crops were completely destroyed, the people could step up planting vegetables and survive this difficult time. But the drought was different. It lasted for a long time. Wherever they went, let alone crops, even the weeds would die.

, Nothing can be planted! What's even more fatal is that after a severe drought, there will inevitably be locust plagues. The overwhelming locusts swept over, and even the hair on the livestock will be cleaned up! What the people are most afraid of is this drought. In order to overcome the drought, I don't know how many solutions have been thought of. Finally, in the late Eastern Han Dynasty, they invented the keel. This thing is a type of water truck. The main body is a rectangular long groove. There are many keel leaf plates in the long groove, which are driven by the sprocket. When used, put part of the water truck into the water truck, and then drive the sprocket to drive the leaf plate. The leaf plate will scrape the water upwards and scrape it to the upper end of the long groove and then send the water out.

As the saying goes, the so-called drought in ancient times did not mean that the river was broken, but that the water level of the riverbed dropped and could not lead out of the canal. At this time, a keel cart brought the water from the low to the high and flowed into the canal. I don’t know how many farmers could solve the urgent needs of many farmers. This is indeed a great drought-resistant weapon, but unfortunately it appeared too late. When it emerged, the Yellow Turban Army all revolted. The Eastern Han Dynasty had no luck and could not use this weapon. Instead, it was cheaper. Cao Wei used this thing a lot when farming in the Central Plains, Hebei, Shandong, Huainan and other places, and played a very important role in the drought-resistant and harvest protection movement.

Li Rui shook his head: "The efficiency of the keel is still too low. It requires continuous driving with human or animal power. It is so tired that it doesn't have much water to pump up."

Zhuge Hui was speechless: "This is a hundred times easier than carrying water to water the grain under the scorching sun, okay?"

Li Rui said: "It can be easier." As he said that, he squatted on the ground, picked up a small branch and drew a big water truck on the ground: "We can use it as a big water truck, that's it, does it look like a big wheel? If we install a baffle and a wooden barrel on this big wheel, then place it in the river. When the water flow hits the baffle, the water truck will rotate, and the wooden barrel on it will draw water. As the water truck rotates, it will bring water to a high place, then flow out from the mouth of the barrel, injected into the wooden sink placed outside the water truck, and transport it to a high place through the wooden sink... Its biggest advantage is that it is completely driven by the water flow, without human and animal power, the water flow does not stop, the water truck rotates day and night, and draws water continuously, which is very convenient."

Zhuge Hui looked at this simple picture and was fully focused. Although the painting was quite simple, she still outlined the image called "tube car" through this simple simple drawing and deduced it in her mind... If Beigong Jing was present, she would definitely congratulate Li Rui: this mechanical energy can successfully operate in Zhuge Hui's mind, then it will definitely operate in reality.

"It's a good thing, worth a try." After understanding some details, Zhuge Hui affirmed Li Rui's almost whimsical idea that he wanted to do nothing and let the river flow to a high place by himself.

Li Rui said: "Why don't we try to get one first?"

Zhuge Hui said: "Okay! But this water truck runs day and night and is easily worn. This shaft has to be made of hardwood. The body of the water truck is soaked in water for a long time. Generally, the wood is easily deformed, so Paulownia... Where can I find these woods for a while?"

Li Rui said: "This is wrapped around me. I know there is a carpenter shop in Jiyang, where there is the wood we need."

Zhuge Hui stood up excitedly: "What are you waiting for? Take me there!"

Li Rui led the way in front, and the two of them quickly returned to the city under the protection of a group of followers and headed straight for the carpenter's shop.

Passing a bustling street, I came to a small river passing through the city, and wandered up the river, a large-scale carpenter shop appeared in front of me. Li Rui said to Zhuge Hui: "I tell you, there are so many woods in this carpenter shop, such as pear wood, pine wood, tung wood, walnut wood and even mahogany, everything is available. If you want to make something special, come here, that's right..."

His eyes swept through a very depressed house. After accidentally seeing something familiar in the yard through the half-open door, he was stunned and forgot to speak.

Zhuge Hui asked: "What's wrong?"

Li Rui pointed to the half-open door: "That thing...that thing..."

Zhuge Hui looked in the direction of his finger and saw that in the weedy courtyard, a plant that looked quite unique was hung on the branches of white balls, densely packed and looked pretty. She said: "That thing is called Baidiezi, which is hard to see in the Central Plains, but there are many in the Western Regions."

Li Rui was very surprised: "Have you seen it?"

Zhuge Hui said: "I went to the Western Regions with my sister five years ago, so I am familiar with it. Some of the farmers in the Western Regions planted some sporadically. Every late autumn, the buds bloomed and spit out white silk, as if the branches were covered with snow. They looked very beautiful." She pointed to the house and smiled and said: "The owner of this house was afraid that someone had been to the Western Regions and brought the seeds back and planted them in the courtyard. Unexpectedly, they would plant them alive."

Li Rui murmured, "What a white stack, it's obviously cotton!" No matter how many years he pushed open the half-closed door and walked in.

The owner of the house had long been missing. The house was requisitioned and several refugees were placed. The young and strong among the refugees had already gone out to make a living, staying at home, and doing housework day after day in their small spaces. When Li Rui, Zhuge Hui and others suddenly broke in, everyone was shocked, especially when they saw the female swordsmen wearing long swords, the children playing in the courtyard showed a look of fear.

An old man basking in the sun in the courtyard saw someone breaking in, immediately got up, looked at the uninvited guests, and asked vigilantly: "You are..."

Li Rui bowed to the other party and said, "Don't panic, my companion and I passed by here. I accidentally saw a strange flower in the courtyard. I felt curious, so I came in and took a look. I hope he could forgive the risk of my liberty."

Seeing that he was polite, the old man couldn't help but breathe a sigh of relief and pointed at the trees full of white "flowers": "Is the strange flower that Langjun mentioned?"
