"What's going on outside? Why is it so noisy? ”

While reading a book, Megumi Yanagisawa asked the master next to him.

"I'll go out and have a look."

The master was about to go out. Suddenly, from outside, a soldier with a face full of ecstasy ran in:

"Report, report. Good news, great news. ”

Yanagisawa and the two stood up in shock: "What good news?" ”

"The steam engine research of the Kyushu Institute of Physics has been successful, and now the disfigured baby is driving a steam car around the entire Laoshan County."

"What?"|

"Success?"

"Quick, go out and have a look!"

Megumi Yanagisawa was quite pleasantly surprised, he didn't expect this to really succeed, and so quickly.

Some time ago, he was still doing explosion tests, and he had the feeling that science was explosions. And after the explosion, it was only a few days, and it was a success?

When Yanagisawa and the two ran to the county yakou, what they saw was an extremely shocking scene.

But seeing that the people at the gate of the county government were crazy, they hurriedly ran forward and chased after each other.

"It's so fast!"

"I can't catch up no matter how much I can't catch up, although I can't run as fast as a horse, but this guy is not tired, and he is much better than a horse."

"Oops, this is just amazing."

"Quick, catch up. I've only taken a quick look, and I haven't seen it all. ”

“……”

The whole street was full of people, the whole street was blocked, and countless people were chasing after it. It's a mess, like an island has entered Laoshan County, and it's chaotic.

The armor that patrolled the streets was also curious, and they jumped their feet and tied their necks to look at the end of the street, but they couldn't see anything. I didn't dare to break away from the team.

Megumi Yanagisawa looked at this scene and yelled: "Prepare the horse!" ”

A moment later, two fast horses rushed out of the county office.

"Drive."

"Get out of the way, get out of the way."

"Get out of the way."

After about five minutes of riding in pursuit, Megumi Yanagisawa heard the sound of 'woo woo' that resounded through the air. Swallowing his saliva, he nervously chased forward.

Chasing further, I saw my son Liu Jinghong running shirtless in the crowd in front of him, so tired that he stuck out his tongue, but there was no trace of exhaustion on his face.

didn't take care of his son, Yanagisawa Megumi drove forward immediately.

Finally, he saw it.

On a simple wooden cart in front of him, white smoke was booming, and a teenager was sitting on the cart and making noise. The car kept moving forward, very fast, a little faster than a human run, but much longer than a human being.

Yanagisawa drove his horse to the front, only to realize that the car was already surrounded by people on horseback. All of them have horses at home, and they ride horses to watch the excitement.

Squeezed out a space, and then looked closely, the board car was equipped with a boiler for boiling water. The coal below is blazing.

"It's amazing, you can run away with a fire?"

There were people next to me who were amazed and couldn't understand the principle.

At this time, the sound of 'Dididi' sounded on the cart. Qin Enze, who was driving, glanced at the pressure gauge and hurriedly pulled the rope at hand.

The gas valve of the boiler opens.

'Woo-woo'

A violent chirp.

"Ahh

"Isn't it going to blow up?"

"Such a big move!"

“……”

I saw that there was billowing smoke coming out of an exhaust pipe next to the boiler. The smoke was terrifying, and I was afraid that this guy would explode on the spot and kill himself. Many horseback riders were afraid to follow.

Why does it still exhale?

Qin Enze laughed out loud and walked away in the violent sound of steam engine power.

It was not easy for Liu Zehui to pull the startled horse, and he looked at Qin Enze who was flying away with white smoke in a daze, and his heart was beating wildly.

The master followed a little nervously: "Don't get so close." That thing is going to explode, and there is a precedent for exploding. Don't get so close. ”

"Let's go, change into formal clothes, and go to the big wind platform. He went to the Great Wind Terrace. ”

“……”

Dafeng Terrace, the entrance of the Kyushu Institute of Physics. Li Zhen squinted his eyes and jumped to look into the distance, and saw a dense crowd roaring over. In front of me was the smoke-filled cart.

After a while, the cart gradually slowed down and stopped in front of Li Zhen.

Qin Enze laughed and jumped off the steam car, hugging his fists: "Master Li, the second-generation steam engine test was a complete success. ”

Li Zhen laughed and patted Qin Enze's shoulder: "Okay, hard work." Let's go, go back and say. ”

The two walked into the Kyushu Institute of Physics together. The students who followed behind hurriedly extinguished the flame of the tested steam car, then turned on the main air plug to completely depressurize, and then pushed the car into the yard.

Behind, the dense crowd saw them all entering, and they all subconsciously followed inside. I want to get a closer look at the amazing steam car.

However, the villagers of Dafengtai all stood up at the same time.

"This is the scientific research center of the Kyushu Institute of Physics, and you are not allowed to enter."

"This is a place where scientists study science, and you are not allowed to go in."

"Just look outside the door. Not allowed in. ”

"Please be self-conscious. Don't disturb the work of other scientists. ”

"Don't go in."

“……”

There was the obstruction of the local villagers in Dafengtai, and those who ran from the county town to see the excitement also consciously stopped, surrounding the entire Kyushu Physics Institute, jumping on their feet, and looking inside. Eagerly discussing the wonders of the steam engine with those who knew and didn't know around me.

Soon, everyone from the Kyushu Institute of Physics arrived.

Li Zhen sat cross-legged on the ground and took out his notebook: "Enze, report the situation." ”

Qin Enze said: "The first experiment was a complete success. Start from Dafengtai, go to Laoshan County, go around the city, and then return to Dafengtai. The whole journey is eight kilometers. The average speed is 35 kilometers per hour. The number of times the pressure value crosses the line is 9 times. Release the pressure a total of ten times. ”

After speaking, Qin Enze frowned and said, "Theoretically, the power of the steam engine should be greater. The speed should reach 40 or more. And I don't think it's perfect, just eight kilometers of travel, ten manual decompression work, it's too inconvenient. And the cylinder is always overheated, and there is no way to cool down, which is a huge drawback. If you really want to run, I'm afraid that after running 20 kilometers, you will have to stop and let it rest for an hour. This requires a great deal of refinement. ”

The students hurriedly recorded these data clearly in their notebooks.

Li Zhen marked the key points: cooling, decompression, and incomplete power play.

Then, everyone fell into a heated discussion, and after discussing for a while, Li Zhen made a decision:

"This is the second experiment, the second generation of steam engines. We also need to develop the third generation, and set a hard rule that the third generation steam engine must solve the problem of cooling endurance, automatic decompression, and maximize the steam power. ”

At this moment, the people outside the gate of the Kyushu Institute of Physics dispersed one after another, and shouted: "The county guard has arrived." ”

But I saw that a group of soldiers and armor immediately rushed into the Kyushu Physics Institute, and then lined up neatly. One by one, their eyes were curiously spinning on the steam car.

Yanagisawa Hui, who was dressed in a big red official mansion, walked in in the midst of a crowd of people, walked in front of Li Zhen, and looked at this descendant happily:

"Congratulations."
