If the brocade book is a treasure, he immediately finds a pen and paper to copy down the method of making the waterwheel. By the time she had finally done all this, it was already dark outside. Looking at the few pieces of paper full of words and drawings in front of him, the big stone in Jinshu's heart was put down.

As soon as I relaxed, sleepiness also swept over. She couldn't help but yawn, turned around and fell asleep on the bed for a minute. When Xiao Yue came to call someone for breakfast, she didn't wake her up, and in the end, Jinshu slept until noon before she woke up.

When she woke up, she began to tinker with the waterwheel, she found a lot of wood and brought it into her room, and then locked the door to prevent anyone from entering. Ye Shi could only hear the sound of ping-pong banging coming from the room outside. She knew what her daughter was worried about lately, so she didn't bother.

While it was time for dinner, Nishiki finally came out of the room. She took a crude model of a waterwheel she had made and excitedly showed it to her family.

Ping An was puzzled: "Girl, what are you doing here?" How do you look like a wheel? ”

The corners of Jinshu's mouth hooked, revealing a smug smile, and explained: "This is called a waterwheel, which can pump water from the low places to a high level, which can just solve the problem of watering the fruit trees on our two hills." ”

Everyone didn't know what was going on, and they opened their mouths wide in surprise, and couldn't help but sigh: "The girl is really amazing!" They didn't doubt the authenticity of Jinshu's words at all, probably because they had been used to her strange methods in the past two years!

Looking at everyone's admiring gaze, Jin Shu couldn't wait to test it. So a group of curious people came to the river with lanterns. It was already dark, and the light of the lantern was not strong enough, so Zhao Hui took the waterwheel instead of the brocade book for the test.

He placed the waterwheel into the river, and with the force of the river's flow, the waterwheel began to turn, and everyone watched as the water was carried out of the river by the waterwheel, and once again their mouths opened in shock. Think about it, if you zoom in on this model, then the river will definitely be able to be carried to a higher place. For the people of this world, this is indeed an epoch-making creation.

That night, Jin Shu was finally able to sleep well. However, she was destined to be unable to use this thing alone, so the next morning, Jinshu took her waterwheel model to Lizheng's house.

After she explained the production and use of the waterwheel, Li Zheng couldn't help but show an amazed gaze. At this moment, he admired this little girl who was only a teenager more and more.

Recently, the villagers were worried about carrying water to irrigate their crops every day, and suddenly they were summoned by Li Zheng, saying that Jinshu had come up with a solution to the problem. At first, some people were skeptical, but after seeing the work process of the water wheel, everyone was amazed.

Needless to say, the villagers went up to the mountain to cut wood and bamboo, and those who knew carpentry took the initiative to take over the delicate work of making waterwheels. It took about five days to build two waterwheels. When the river was carried up by the waterwheel and flowed into the pre-dug reservoir through the connected bamboo, everyone could not help but applaud and cheer.

These five days of brocade books are not idle. The vegetables and fruit trees she grows are large, and the two waterwheels in the village are simply not enough, so she has hired a lot of people in the town to help. There are people who make water wheels, and there are people who dig cisterns, and it took about five days before and after.

Although the water wheel still requires people to carry water from the cistern, it is much easier than carrying water directly from the river.
