After more than an hour of inking, everyone became more and more impatient. Xu Shenxue also knew that it was too much, and in the midst of complaining, he finally led everyone to the well, and did not forget to say:

"I just want to tell you that bitterness comes before sweetness. You see, first walk, when you get tired, then you eat watermelon......"

Xu Shenxue told the fable.

Everyone including Li Zhen was upset when they heard it.

Qin Enze sighed and muttered, "I don't want to eat watermelon at all." God, he is bitter and then sweet. ”

"Don't tell this kind of childish fable."

“……”

Xu Shenxue's face was expressionless, and he resolved this embarrassment in silence.

Li Zhen walked to the mouth of the well, peeked down, and there were several buckets soaked in it, each bucket was filled with watermelons.

Hurriedly rolled up his sleeves and grabbed the gallows at the wellhead with both hands.

This well is a pit well, and the main way to get water is to hang a bucket with a rope to get it. In order to save effort, a gallows was built at the wellhead, and the rope was twisted to achieve the effect of labor-saving.

This gallows is often lubricated and is very easy to use and labor-saving. Li Zhen just grabbed the 'Z' shaped handle of the winch with one hand, and he could easily twist the winch to lift the bucket.

And when Li Zhen grabbed the handle and twisted it around, the whole person let go of his hand and was stunned on the spot.

There was a 'click', and a thunderbolt flashed in my mind.

How many days of gloom and gloom turned into an instant burst of inspiration. At this moment, he grabbed an inspiration. At this moment, he also grabbed the drumstick that beat the drums of Kyushu's revival war!

The whole body froze on the edge of the well, his eyes straightened, and his expression stiffened.

Xu Shenxue asked: "What's wrong?" ”

After a while, a look of ecstasy appeared on Li Zhen's face, and he muttered, "I know." I know...... That's it, that's it. ”

"I see!"

"I see!"

Li Zhen jumped up excitedly, rushed down the platform, grabbed Liu Jinghong's neck and shook it vigorously and shouted: "I know!" ”

"What do you know?" Liu Jinghong was dazed.

Li Zhen laughed hysterically: "I know, hahaha, I know how it can do repetitive movements." I got it, I got it, I figured it out. ”

All the people standing by the well were incredulous, with a look of ecstasy, and surrounded Li Zhentuan.

"You got it?"

"What is it?"

"What the hell?"

"How can I do repetitive exercise?"

"Do you understand? Oh my God, have you finally figured it out? ”

“……”

"Quick, quick, call everyone in the lab. Hurry, hurry! ”

Li Zhen shouted anxiously.

Xu Shenxue's face was full of surprise and uncertainty, he also realized the importance of the matter, and shouted: "Hurry, go quickly." ”

Fang Hanxian pulled out his legs and ran out.

ran to the Kyushu Physics Institute in a hurry, pushed open the door, suddenly overturned the table, and roared: "Don't sleep!" ”

A thunderous explosion woke up all the people who had fallen asleep, and everyone looked at Fang Hanxian, who usually didn't dare to speak loudly.

Fang Hanxian shouted in a trembling voice: "Quick, go to the well." Li Shi said he knew, he found out. He said he knew the answer to the problem of repetitive piston movements. Quick, everyone go to the well. ”

'Hum', the whole laboratory exploded in an instant.

No one spoke, they all got up with a grunt and ran out like crazy.

At the door, Qi was stunned and stood up, watched a large group of people running out, and muttered: "It's going to be cracked?" ”

Fan his two thighs and ran forward, forgetting to throw down the bench leg he was holding.

The movement in the laboratory alarmed other students who passed by. They saw this group of people who were so crazy that they couldn't be reasoned, and each of them rushed out of the laboratory with a nervous face, and their hearts were full of curiosity.

"What's wrong?"

"This group of people hasn't come out since they were stationed in the Great Hall. Thunder can't move, why are they all crazy and running out today? ”

"Could it be...... Did you find out? ”

"Have you solved the puzzle?"

"What is it?"

"Quick, let's take a look!"

"It's the well side of the playground. Come on, come on. ”

“……”

The people waiting by the well only heard the loud sound of 'booming' in the distance, and couldn't help but turn their heads to look.

But I saw that there were more than a dozen people at the head, all of whom were students of the Kyushu Institute of Physics, and each of them was full of nervousness and panic. Running this way like crazy, the speed is so fast that he can't even catch up with the long-legged Qi stunned. Each one of them was like crazy.

Behind them was a large group of students who rushed from the direction of the school building. There are about thousands of people.

All of them were alarmed by the anomaly of the Kyushu Institute of Physics, and they came to see the excitement.

In the classroom, when they heard the movement outside, everyone leaned on the window and looked down. Listening to those calls, the teacher who gave the lecture was pleasantly surprised: "With such a big movement, could it be that they solved that particularly unsolvable problem?" That's a big deal. You study on your own, I'm going to take a look. ”

With that, the teacher who was lecturing threw down his book and ran downstairs.

The students in the classroom were silent for a moment. In an instant, they all stood up and rushed downstairs.

The entire Fuxing University was in chaos, because Li Zhen's words caused a sensation in the Kyushu Institute of Physics. The students who have been concerned about the Kyushu Institute of Physics were alarmed by the abnormality of the Kyushu Institute of Physics.

Li Zhen said that everyone from the Kyushu Institute of Physics should come, but ...... The whole school came.

He stood on the platform of the well, looking at the people below, and they all looked at him with a blank look.

In the silence, Fang Hanxian's most introverted person became manic at this time, stomped his feet, and yelled: "What the hell is going on? ”

Li Zhen came back to his senses, and his face was full of wild laughter: "After two weeks, a breakthrough has finally been made today. I finally know how to solve the problem of repeated piston movements. ”

"How to fix it?"

A group of people from the Kyushu Institute of Physics gathered around and asked nervously.

And everyone except for the Kyushu Institute of Physics was staring at each other with big eyes and blank faces. Do not understand......

What piston repetitive movement? What is Piston? What does repetitive exercise mean?

Li Zhen led everyone to the well, holding the winch of the gallows with one hand: "You see, if I shake the gallows, the winch will rotate." We're all thinking in the wrong direction, we're just thinking about how to put the force on the piston and make it move repeatedly. But what we should be thinking about is how to make the piston move repeatedly all the time, whether it's on the piston or something. ”

Qin Enze's eyes brightened, and he asked, "And then?" ”

Outside the Kyushu Institute of Physics, everyone was stunned.

What do you mean? What force? What does it do? Do not understand!

Li Zhen pointed to his right hand: "If my arm represents the piston, my physical strength represents the thrust of steam." The upper part of my arm is always moving in a straight line, and the piston is moving in a straight line in the cylinder. But my arm has a joint at the elbow, so the force of this linear motion is transmitted to the forearm, and then it is transmitted to the winch around the center of the winch, and the force changes, from a linear motion, to a circular motion. The circular motion is applied to the winch, which produces a rotational motion. ”

"We shouldn't be constantly imagining how to change the pistons. What we envision is how to use the piston to change the operation of the force. According to the conservation of energy, energy is constantly transformed. And we ignore the conversion of force. It converts linear motion into circular motion. We were wrong before, we should not have imagined changing the piston, we should have imagined adding another device to change the energy and convert the energy in addition to the piston. ”

"And this kind of device, maybe it's called ...... Crank linkage! ”

“……”

The voice fell.

All the staff of the Kyushu Institute of Physics were stunned on the spot, looking at their arms, and then at the imported winch.

Silence.

After being silent for a long time, Liu Jinghong opened his mouth exaggeratedly, and laughed wildly in an extremely hoarse voice: "You are a genius!" ”

Everyone from the Kyushu Institute of Physics immediately surrounded him, lifted Li Zhen up, threw him into the sky, then caught it again, and then threw it into the sky again.

Everyone was laughing maniacally.

"You're a genius!"

"Crank linkage!"

"Hahahaha, crank linkage. No, it should be called an arm link haha,"

"Wouldn't that solve the problem of changing motor behavior? Hahaha. ”

"We're going to make it!"

"We're finally on our way to success!"

“……”

Thousands of people rushed to the school when they heard the news, and quietly looked at the 33 people who were carnivaling at the wellhead. His face was dazed.

Crank linkage? Linear motion? Circular motion? Conservation of energy?

They didn't understand any of them, they didn't understand what the people from the Kyushu Institute of Physics were talking about, what they meant.

"Back to the lab. Fast! ”

“……”

With a hearty howl, the 33 unkempt people trembled with excitement. In the unconscious laughter, he frantically pushed away the crowd and rushed back to the laboratory.

Thousands of people in the whole school looked at this group of demonic people in silence.

Everyone's voice: suddenly, I envy them......

They have a kind of that belongs only to them.
