However, looking at Qin Mengdie's happy face, Feng Yuye knew with this expression that this was what the hell she had in mind.

It's not early in the morning, so Qin Mengdie doesn't sell it: "Uncle, tomorrow morning, you gather all the people in the village together, and I have a way to solve the water source problem in your village." ”

The old man looked at the surprised expression on Qin Mengdie's face, as if he had seen some rare treasure, but looking at Qin Mengdie's little girl, he still made a mistake in his heart: "Is it credible for a little girl like you to speak?" If you don't come tomorrow, how can I explain to the villagers? ”

At this time, Feng Yuye always seemed very useful, he took off a piece of jade on his body and handed it over: "Uncle, you take this jade plate back, this jade card is the government must obey when it sees it, and this jade is priceless, we don't need to lie to you." ”

The old man took the jade plate in Feng Yuye's hand, the ancient people had the ability to appreciate this jade, plus the carving on the jade, it looked very valuable, and he didn't think about it himself, so he should come down quickly.

After the old man left, Qin Mengdie hurriedly asked, "Rainy night, is your jade card heavy?" Why is it just given? ”

Feng Yuye looked at Qin Mengdie's little face that kept money, and couldn't help but smile: "That is not important, it's just worth some silver taels, you said that you can solve the water matter, are you asking for rain?" ”

Qin Mengdie was stunned by this begging for rain, and then she covered her mouth and laughed: "Rainy night, do you think I'm so unreliable?" What I'm going to do is a waterwheel, and if this thing is promoted, it can solve a lot of drought problems. ”

"Let's talk as we go. Otherwise, someone will come out to look for us in a while, it will be dark, and it will not be safe. Saying that, Feng Yuye took Qin Mengdie's hand and walked back.

Qin Mengdie enjoyed such a two-person world very much, and let him hold hands: "Go back, I'll draw you a detailed drawing of the waterwheel, you gather the carpenters in the team to work, let's make a small model overnight, the experiment is successful, and then let the villagers start to take action." ”

Feng Yuye had no doubts about Qin Mengdie's thoughts, and she had never let herself down so many times. Even every time she has something on her mind. He was looking forward to seeing it: "Okay, I'll let General Li go to the carpenter when I go back." ”

The two met in the barracks, and the order was sent on a rainy night, but there was no water source today. Everyone can still only eat dry food. Not having a water source is really hard for everyone. You can't eat hot things, you can't wash up, but you're out on the road. These must be overcome.

Qin Mengdie returned to the tent, and began to draw drawings while nibbling on steamed buns, the waterwheel is to use the turbulent water to turn the wheels, so that the water cylinder mounted on the wheels automatically pulls water and lifts it ashore for irrigation or drinking.

Its advantage is that it can lead the water flow from low to high, but this time the distance is a little far, so it is a little difficult to actually do, of course, the principle is right, and it can be slowly improved in the future.

This thing is not difficult in the first place, but after eating the steamed buns, this drawing is almost finished.

Soon Feng Yuye walked in with two little soldiers: "Mengdie, the uncle of this brother and the two kings is a carpenter, and they all know a little bit about it. ”

Qin Mengdie also understands that there are no carpenters in this army, and those with skills will not come to join the army. Most of these people who came to join the army were people with many families and had no skills.

However, this waterwheel is not difficult, and hurriedly beckoned the Wang brothers to come over: "You look at the drawings and make a small sample, it may be done in one night?"

The two brothers looked at the drawings, and Wang Da nodded confidently: "General Qin, it's done in the middle of the night." ”

Feng Yuye said: "This king will send someone to cut wood, and it will start in a while." ”

Qin Mengdie had to admire Feng Yuye's IQ, and did things in such an orderly manner: "That's good, if you do it well, you have to experiment, if there is a problem, you have to improve." ”

Qin Mengdie carefully talked about the structure of the drawings again, and the Wang brothers were stunned when they heard it, and they didn't believe it in their hearts, but after all, this is a general, and if he can do things for the general, he also has merit, no matter whether he succeeds or not, he just needs to make what the general asks.

After a while, the wood chopping came back, Qin Mengdie hurriedly took Wang Jia's two brothers to start making, and the camp tent suddenly became lively, several generals and lieutenants, as well as commanders and commanders, all crowded in, and even Zhao Yan came to see this new invention.

There are many people who can't let everyone see it, Qin Mengdie grabbed all the people who watched the excitement here to work, the strength of the number of people is great, it has just reached midnight, the prototype of the waterwheel is basically completed, Qin Mengdie asked people to prepare a basin of water.

This basin of water was collected by several people's portable kettles, and it was difficult to make it up, and then the small waterwheel was put into the water, and there was no water flowing here, so it could only be manually shaken by hand to make the waterwheel spin.

When they saw that the waterwheel began to turn, it brought a lot of water, and the water that had accumulated together flowed to a fixed place, and flowed along the channel they had built, mainly because the canal was upward, and everyone was amazed, and for the first time they saw that water could flow upward.

The cheers in the tent came and went, one higher and higher, and seemed a little out of place at midnight, but the sound of joy struck everyone's nerves.

After a few adjustments, the waterwheel was considered to have passed the test completely and could really be put into practice.

Qin Mengdie looked at Feng Yuye: "Lord Wang, tomorrow I want to leave Vice General Liu and the Wang family brothers, and then give them a small team of people to help the people make the waterwheel, as for the canal, the villagers can do it slowly, but I think the part of the waterwheel is still left to leave a person, I can rest assured, leave them horses, it will be completed in one day, and the horseback riding will catch up with us in two days, without delaying the trip." ”

Without waiting for Qin Mengdie to speak, General Li Yin Li stood up: "How can that be?" General Qin's invention is indeed beneficial to the people, but we are soldiers, we are here to protect the country and resist aggression, how can we help the people do farm work? ”

This General Li rarely speaks, but he is an old general, and his words have weight, Feng Yuye just wanted to speak, Qin Mengdie spoke first: "General Li's words are wrong, we have an important task, but the people are the foundation of the country, where did the grain and grass come from for our expedition?" It's all the people's teaching taxes, but if the people have no income, we have no food and grass, so how can we fight? ”

"General Qin, this is a strong word, disasters are only in a small number of areas, and these things are not within our jurisdiction, it is enough for local officials to manage them, General Qin's drawings and this model are enough to leave to the people, we can't leave soldiers to repair waterwheels." General Li spoke righteously, and his voice was loud. (To be continued......)
