In the midst of the flames, the boiler was heating, and the water in it was boiling or not.

And I have to say that Liu Jinghong is very divergent thinking, and he can think of many, many details.

After the flame burned for three to five minutes, Liu Jinghong opened a tether on the boiler and explained to Li Zhen:

"I don't think we know if the water in the boiler is boiling or when the internal pressure starts to develop in the boiler. So I made a small hole in the boiler and made a whistle shape. As long as this tether is opened, the small bloat is opened. If there is internal pressure in it, the internal pressure is released from the small hole, and the whistle is blown. I can tell that the cylinder is already generating power. ”

Li Zhen glanced at Liu Jinghong appreciatively and patted him on the shoulder: "You can think of this step, it's really unexpected to me." Next time, let's make a pressure gauge. If you look at the pressure gauge, you can know the value of the internal pressure and the value of the power. ”

"Pressure gauge?" Liu Jinghong asked, his eyes moved, he understood it a little, and from the literal understanding, he already had some thoughts in his heart.

It's not just Liu Jinghong who is smart enough to hear the words pressure gauge. Many people at the Kyushu Institute of Physics were shocked and began to ponder.

Except for the people from the Kyushu Institute of Physics, no one else could understand it.

Others did not study the steam engine and did not go through this series of academic processes. They have very vague notions of these.

After about six minutes, the crowd suddenly closed their mouths.

"What sound?"

But I heard a 'hissing' sound from the boiler. But no white smoke came out.

Liu Jinghong clapped his hands and laughed: "Air energy has begun to appear in it." ”

As soon as the words fell, the hissing voice suddenly changed into a sharp 'sentence by sentence', and at the same time, wisps of faint white smoke rose from it.

"Momentum. Quickly, turn off the air tether and save steam power. ”

Some classmates immediately plugged the bolt back on, and in an instant, the sharp sound of 'sentence by sentence' disappeared.

"Is that okay?"

"As soon as that voice sounds, is it full of energy and is about to start running?"

"Why hasn't that disc moved yet?"

“……”

The onlookers were in a commotion, but the people of the Kyushu Physics Institute were all full of sneers.

Finally, it was Qin Enze's turn to come out and pretend to be forced, he walked to the boiler and said loudly: "The mass of the disc exceeds the mass of the steam power, so theoretically speaking, steam cannot push the disc to run." ”

The words fell, and there was a commotion.

"What about playing?"

"Can't push? What's the use of that. ”

"So you're just proving that fire can make water hot? Hahaha. ”

"Kidding us?"

“……”

Qin Enze laughed: "So, this needs a driving force." This initial power is to pluck the disc by hand to make the disc appear the first ray of inertia. Under the inertia, the piston is pushed to perform repeated movements. Under inertia, the steam force is excited, and it can keep circulating and rotating. ”

Everyone looked at each other and explained professionally, but they couldn't understand it.

Qin Enze walked near the disc: "Look at it." ”

As he spoke, he grabbed the edge of the disc and flicked it in a clockwise direction.

With a flick of it, the disc spun slowly. The crowd of people from the Kyushu Institute of Physics stared at the research, especially Li Zhen, who was more nervous than anyone else.

Can it be done?

When the disc rotates half a turn, the crank connecting rod connecting the center of the circle begins to expand, driving the piston to begin to expand and contract.

At the critical point of the half-circle, there was a small pause.

At this moment, all the people who knew the principle of the Kyushu Institute of Physics gasped, and they only felt that this small pause was related to life and death. This momentary pause seems like a century long.

But in the next moment, the pause was gone. The disc continues to rotate in a clockwise direction.

And this time, it was pushed out by the pistons. But it's the piston that pushes it to rotate in the second half of the circle.

'Knock'

The hearts of all the people in the Kyushu Institute of Physics beat wildly with the success of this second half of the circle.

The disc begins to rotate for the third half-turn, and when it reaches the critical point of the fourth-half-turn, there is less time to pause.

Continuous rotation.

Lap 5, lap 6, lap 7.

It began to spin faster and faster, and after each lap, it began to double its speed.

Lap 20......

Everyone at the Kyushu Institute of Physics trembled.

Liu Jinghong's eyes were red, and he muttered: "Cheng...... It worked? ”

"Ahh

"It worked!"

"Hahahaha, it worked!"

“……”

Everyone at the Kyushu Institute of Physics hugged each other, jumped their feet and shouted to the sky, and it was successful.

The onlookers all opened their mouths in astonishment.

The speed of the disc is getting faster and faster, from the initial half of the circle to the current rapid rotation. The speed is extremely fast, about a minute can reach more than 100 revolutions, and there is the sound of breaking the air from the high-speed rotation nearby.

"This ......"

"They succeeded!"

"They really succeeded."

"What, what kind of science is this?"

"Why, why is it that he can spin faster and faster just by gently flicking half a circle of his hand?"

"It's amazing, is this the steam engine? What is it full of? ”

"It really worked!"

“……”

Xu Shenxue took a deep breath and exhaled heavily, looking at the plaque of the 'Kyushu Institute of Physics' behind Li Zhen, his heart was surging.

And they really succeeded.

Suddenly, the spinning disc seemed to freeze.

Li Zhen looked at the speed of the disc rotation and muttered, "How do you feel like it's going to stop." ”

Fang Hanxian and the others hadn't seen the movement of the disc yet, and laughed wildly: "Does this represent the era of the entire Kyushu from manual to steam power?" Its success is enough to shake the world. ”

"Yes, this disc is enough to drive a carriage."

"It's a sign that the age of steam is coming."

At this time, Qin Enze laughed and walked to the disc, and proudly looked at the group of students in front of him who were looking at him with envy: "Under the leadership of Master Li, my Kyushu Institute of Physics can proudly announce it." ”

Li Zhen's pupils suddenly shrank, and he saw that the plug with small air holes on the boiler began to beat at a high frequency, as if it was struggling. And the high-speed spinning flywheel suddenly got stuck. In an instant, it went from spinning at high speed to braking suddenly.

Li Zhen was shocked, he knew something was wrong. He knew what was wrong.

"Qin Enze, get out of the way!"

When Qin Enze was about to announce something, Li Zhen suddenly roared.

Qin Enze looked back puzzled: "Huh? ”

'Bang'

A loud bang resounded throughout Fuxing University, and white smoke billowed and filled the entire scene.

'Hiss' water poured over the flames, extinguishing them and emitting even thicker white smoke.

The temperature of the entire scene rose several degrees in an instant, white smoke filled the whole field, and water vapor filled the entire space.

"Ahh

A heart-wrenching scream was heard.
