Cannon's little husband

"Water wheel?" Mingcheng stopped walking, "What is a water wheel?"

"Uh, it's a... device that sends water to high places." Lian Qi didn't know how to explain it. Although the water wheel had been eliminated by history in his previous life, in the long farming civilization , The water wheel, or the drum car, once occupied a very important position and was the first application of water energy by the ancestors.

"There is such a thing?" Mingcheng asked in doubt.

Lian Qi nodded, "I still remember the principle, I will draw a picture later, and ask Uncle Xia for help to see if I can make it."

Mingcheng nodded, didn't get entangled in this, and after a few more instructions, he left. After walking out the door, he seemed to think of something again, turned to Lian Qi and said, "Brother Qi, the other place in your house Fifteen acres of land, are you going to plant peach trees all the time?"

Lian Qi was taken aback, "Ah, I plan to move those peach saplings to the mountains to plant food again."

Mingcheng nodded, "That's fine, if you need help at that time, just say so, don't resist yourself."

Lian Qi smiled, "I know, Third Uncle Ming."

After sending Mingcheng away, Lian Qi got a piece of paper from Lian Rui, but when he picked up the pen, he froze, he...he couldn't use a brush!

"Brother?" Seeing that Lian Qi hadn't written for a long time, Lian Rui couldn't help being puzzled.

"Cough cough." Lian Qi coughed a few times, and then put the brush on the pen rest, "Well, I'd better use a branch to draw on the ground outside first, to determine the proportions, and then, when the time comes Please, Ari, transcribe it on paper for me."

Lian Rui opened his mouth, wanting to tell the eldest brother to use it, but then remembered the price of pens, inks, papers and inkstones, and the current situation of his family, and swallowed back the words that were about to be exported, his voice was a little dry, "Okay, when the time comes I will Help big brother transcribe it."

At the same time, the young man's hands behind his back have been tightly clenched into fists, and he secretly swears in his heart that in the future, he will definitely be named on the gold list, and support the whole family, so that his elder brother doesn't have to be so frugal!

Lian Qi didn't know that his behavior of not wanting to reveal that he didn't know how to write with a brush aroused the brains of his younger brother. He was thinking hard about the shape of the waterwheel!

The waterwheel in his impression is something like a big bicycle wheel. As for some more elaborate structures?He really didn't pay much attention.But it doesn't matter, he believes that the wisdom of the working people is infinite, and they can definitely make a waterwheel!make a fist!

Well, but, what is the principle of the waterwheel?Lian Qi remembered that it seemed that the driving force of the water flow was used to push the huge waterwheel to turn up and down, and then the bamboo tubes originally tied obliquely to the waterwheel could transport the water to high places.When reaching the highest point, as it falls, the water in the bamboo tube is poured out from the height, and then flows along the erected aqueduct to the farmland that needs to be irrigated.

In other words, what is the arc of the bamboo tube tied obliquely?How many pieces of wood are there?How do you determine how fast the water can move the waterwheel?

When he really started to draw pictures, Lian Qi scratched his head and scratched his head, wishing to go through all his memories of more than 20 years.

But it's a pity that no matter how hard he racked his brains, what fell on the ground was only a circle.

It doesn't look like drawing the structure diagram of a waterwheel, but it looks like drawing cakes to satisfy one's hunger.

Looking at the "big cake" on the ground, Lian Qi threw the branch in her hand, coaxed Lian Rui to study and study, and sat cross-legged in the yard by herself, worrying, what should I do?

However, after only three seconds of worry, Lian Qi heard the sound of tinkling beside her, and turned her head to see that Tang Wuyu was cutting a board.

"Brother, what are you doing?"

"you guess."

"..."

When did my brother Gao Leng learn such a cold humor?

"Make toys." After admiring Lian Qi's constipated expression enough, Tang Wuyu seemed satisfied, and three words popped out of his mouth.

Toy?Looking at the wooden boards that were cut into small pieces, the light bulb on Lian Qi's forehead suddenly lit up, could it be a trick pig?

But soon Lian Qi wilted again. Toys and so on were given to Lian Yu. Now Lian Yu can still play with toys at home. Lian Ying has already started to learn how to do needlework. When I have nothing to do, I get together with her friends to study acupuncture.

Can Lian Qi still grab a toy from a child?That's obviously impossible!

After complaining for a while, Lian Qi went back to work. The board Tang Wuyu had just cut gave him inspiration. It seemed that there were scrapers on the waterwheel, and the water flow hit the scrapers, making the whole waterwheel Start to rotate, but how big should this scraper be?

Lian Qi has been busy with the structure diagram of the waterwheel for several days. The structure has not been finalized yet, so he is too embarrassed to go to Uncle Xia.

However, he did not expect that three days later, Tang Wuyu would directly give him a huge surprise.

"This... is this for me?" Lian Qi looked at the waterwheel model on the table with some excitement, and was at a loss for a while, "Didn't you say that you made a toy?".

"Well, don't you like it?" Tang Wuyu raised his eyebrows, making a gesture to take back the exquisite waterwheel model.

"Don't, don't, I like it, I like it! I like it so much!" Lian Qi hurriedly protected the waterwheel model and said in a loud voice.

He stretched out his hand and twirled the small and exquisite water wheel, and after playing for a while, Tang Wuyu reminded him, "Aren't you going to try it?"

"Try it?" Lian Qi was taken aback, "How?"

Tang Wuyu silently took out a water tank, placed it at an angle, and fixed the water wheel in the water tank.

Seeing Tang Wuyu's movements, Lian Qi understood Tang Wuyu's actions instantly, and walked into the kitchen. When she came out again, she had a gourd ladle full of clean water in her hand.

Looking at the gourd ladle of clear water, Tang Wuyu gave Lian Qi an appreciative look.

Lian Qi laughed, "Then shall I pour water?"

Seeing Tang Wuyu nod his head, Lian Qi tilted the ladle and poured clear water into the sink, rushing past the exquisite waterwheel model.

Under the impact of the water flow, the model waterwheel moved slowly. When the bamboo tube reached the highest point, the water flowed into the aqueduct and fell directly to the ground. Because there was no basin to catch the water, Lian Qi was splashed with muddy water.

But at this time, Lian Qi didn't care about these at all. After emptying all the water in the gourd, the small model of the waterwheel stopped working because there was no impact from the water flow.

Lian Qi took a deep breath, took another breath, still couldn't hold it back, and stepped forward to give Tang Wuyu a big hug, "Brother, you are really amazing, ouch! I love you so much!"

The author has something to say: Tang Wuyu: I am an elite disciple of the Tang Sect here, yet you still go looking for someone else?Are you looking down on my organization of the Tang Sect? [sneer.jpg]

Lian Qi: Brother, I love you so much!

Tang Wuyu: ...Forgive you this time.

hehehe~
