After five years of teaching support, Daming became an empire on which the sun never sets.

Chapter 300

"Is it necessary to hide so far away?" Xu Da turned his head and laughed at everyone.

After a while, he felt a huge force coming from the inside of the pot, and he kept pushing up the lid of the pot, competing with his strength.In less than a few breaths, he showed signs of being unstoppable.

With my Xu Da's strength, I still can't hold the lid of the pot?Anyway, I can be considered a martial arts master!
Xu Da refused to admit defeat and continued to press down hard.

In the end, he even squatted down, sinking his qi into his dantian, using his true qi.

"Let go, it's dangerous!" Seeing this, Qin Yu hurriedly yelled.

As soon as the words fell, there was a sound of "Peng", and the pot exploded, and the iron pot lid was blown apart.

The scalding boiling water immediately splashed around, and the more destructive steam rushed towards Xu Da.Xu Da strode sideways and hurriedly dodged, but he still couldn't dodge, his face was scalded by the steam, and his face was flushed red.

Fortunately, he has martial arts and agility, and did not cause too serious burns.

When Qin Yu and the students saw the hot water falling, they immediately dodged.

Just like the teachers and students in a martial arts school, he and this group of students have also practiced martial arts.

"How are you? Is your injury serious?" Xu Miaojin hurried over and asked with concern.Because he couldn't recognize him, he didn't call him dad but called you, but it could be seen from his eyes that it was a worry from the bottom of his heart.

Could it be that this little girl worships the tough uncle?Qin Yu was surprised when he saw this.Um, um, teenage girls have weird ideas, so I have to find a time to talk to her, so as not to go astray.

"It doesn't matter, it doesn't matter, hiss..." Xu Da said, "Fortunately, I hid quickly just now."

"I told you enough is enough, but you don't listen. Can the power of steam be countered by manpower?" Qin Yu said, "Steam can even push a train. How can your mortal body resist it?"

"Aren't you stupid?"

"I'm sorry in my previous life, I was a little bit unwilling to admit defeat just now." Xu Da said awkwardly.

"I think you should ask Miss Lingshu to get you some medicine. If you lose your face, you won't be able to find a wife." Qin Yu said, "But before you leave, please tell me whether the pressure of the steam is too high." I also saw him In fact, his injury is not too serious, he just hid a little fast.

"Big, it's too big, it's really terrifying!" Xu Da said, "I've exhausted all my strength just now and couldn't hold it down, and it gives me the feeling that all my strength is less than one-ten-thousandth of steam. "

"It's like a martial arts master. As soon as I exerted my strength, the opponent's true energy surged towards me and defeated me in an instant."

"Who told you not to obey the command." Qin Yu sighed, "You are still a martial arts master. Can a martial arts master be compared with steam? As long as the temperature of the fire source is high enough, the power of steam can theoretically reach infinite."

"Infinity!?" The crowd was speechless.

"I'd better go to that little girl for help first." Xu Da felt the burning pain on his face, and after speaking, he turned and went to look for Lingshu.

"I'll take a look too." Xu Miaojin followed behind him and left.

It seems that we really need to talk to her, Qin Yu thought.

"I didn't expect that I, Xu Da, was rarely injured in battles in my life. Hu Yuanqi's man Wang Baobao couldn't hurt me, but I was injured by the steam today." After walking out of the Lujiacun Primary School, Xu Da was filled with emotion.

"This involves the knowledge of immortals and physics. Is your flesh and blood able to compete? Mr. said, as long as you learn physics well, you can destroy a city with one bomb, and instantly wipe out tens of thousands of people in the city." Xu Miaojin looked at the sad face on his father's face, and complained about his father, "You should have obeyed Mr.'s orders just now, and let go if you can't hold it down. You will suffer a big loss now, right?"

"I just think that the power of the steam cannot be so strong." Xu Da said awkwardly.

"What do you think?" Xu Miaojin said, "I don't want you to think, but Mr. must think."

"In terms of physics, we have to listen to Mr. everything. Even if you think something is impossible, you can't make your own decisions."

"My daughter is right." Xu Da sighed, "The power of steam is terrifying, completely beyond normal people's thinking. From this, it can be seen that Mr. Qin said that one bomb destroyed a city and wiped out tens of thousands of people in an instant. It's really possible."

"It turns out that you have never believed Mr.'s words." Xu Miaojin sighed.

"How can you make me a normal person believe this kind of thing?" Xu Da said, "Destroy a city with one bomb, and wipe out tens of thousands of people in an instant. Isn't that power comparable to that of a god?"

"Whether you believe it or not, I believe in Mr. unconditionally." Xu Miaojin said.

"But what he said is too exaggerated!" Xu Da said.

"My daughter doesn't think it's an exaggeration." Xu Miaojin said, "Even if my husband says he can fly across the sky, my daughter will believe it. Maybe he can really do it, because my husband told us about airplanes."

……

on the playground.

"Have everyone seen it now?" Qin Yu said, "The power of the steam is beyond your imagination."

"We can't take it for granted that the kinetic energy of steam is very small just because we see that steam can only push the lid of the pot. In science, taking it for granted will make everyone miss a lot of things."

"For example, when we see an apple falling to the ground, we take it for granted, so we can't discover gravity."

"Sir, the lesson is correct. In physics, it is not correct to take it for granted." Zhu Xi said.

"So you have to test it yourself before you can see the truth of the matter."

"It's better to say what my husband often said. Science can't be false. Doing experiments and obtaining data by yourself is the only way to seek truth from facts."

the crowd said.

Through the experiment and demonstration just now, this group of students realized how wrong their previous thinking was.

The illusion that the steam pressure is very small has also misled the ancient Chinese sages for thousands of years, so that they did not invent the steam engine.

Sure enough, it was a blindfold.

The pressure of the steam just now was really scary, and the frying pan was directly fried in less than 1 minute, and the tin lid was completely fried.

"Steam has such great power, if it can be used properly, it can indeed do many things..."

The thinking of this group of students suddenly became active.

"To manufacture steam turbines, we must first understand steam engines." At this time, Qin Yu said.

"In the west in the [-]th century, the appearance of the steam engine directly triggered the first industrial revolution. The so-called industrial revolution means that earth-shaking changes have taken place in industrial manufacturing, replacing traditional manual manufacturing with machine manufacturing."

"That is to say, as long as a steam engine can be created, it can be immediately used in all walks of life in society, completely changing the mode of social production, replacing manual work with machines, and greatly improving social productivity."
