"So no matter how heavy or heavy, two things can fall from a high place at the same time and land at the same time!" Duran told the students about physics on the podium.

"Teacher, you are wrong. I have done an experiment. I threw down the feathers and coins at the same time, and the coins have always hit the ground first!" There were one or two students in a class who liked to show off.

Duran rolled his eyes, "Sir Smith, your spirit of exploration is good, but I hope you can be more careful next time you read the book. My previous sentence has a premise, that is, in a vacuum state, it is too difficult for you students to consider air resistance, so everything we say now is generally not to consider air resistance!"

Smith, a handsome guy, has excellent grades, a wealthy family, is versatile in sports, and admires the hero Satan. He just likes to go against his teacher. As a new teacher, Duran is also within the scope of Smith's hatred.

"Okay, what we are learning about in this chapter is gravity and gravity acceleration. Everyone should have previewed like Smith. So I will start asking questions now. If anyone can't answer, then stand in the corridor!"

Du Lan Chunxin wants to establish his authority so that he can make these furry children obedient!

"Hey? Why is this so?" The student's complaint was directly ignored by Duran.

"Jack!"

A tall male student stood up from the last row.

"What will the amount of gravity an object is subject to?"

"Uh, I don't know this!"

"It's the mass of an object that is related to the local gravity constant! Well, Jack goes to the corridor and stands!"

Duran asked questions one by one, and in the end, only Smith with glasses and a girl with double ponytail stayed in the classroom. Duran knew that there were two top students in his class.

After class, Duran was immediately called by the principal to the principal's office. Almost all the students were rushed to the corridor, which was unique since the establishment of Orange Star High School, although this school has only been founded for a few years.

"Although our high school does not have much history, under the inspiration of the great savior, Mr. Satan, our school has the best students and teachers. To be honest, Mr. Duran, your approach is already dissatisfied with students. I hope you can apologize to the students!"

"Principal, are you showing the lower limit? Believe it or not, I will buy the entire Orange Star Academy and let you lay off after you let it go!" Duran was carelessly opposite the principal.

"Teacher Dulan, look no further than a teacher!"

"How come I'm not like a teacher? You know, I have taught several excellent students, each of which can stand on my own. It's several times better than the students in the school." Duran said of course, he was his disciples in the Naruto World.

"Teacher Dulan, no matter what, you are too much this time!"

"I have a say in education, so don't say much, Mr. Principal. Our Orange Star High School is the most famous school, and it is the school that the savior Satan once visited. Of course, we need the most outstanding students in the Education Department. So I will educate them in my way! If you don't want to be laid off, don't interfere with my educational methods!"

Duran's educational method is to throw students to others, as he did before, whether it was during the Jingwu Sect, when he led a ninja team, or when he was educating his daughter.

However, this time Duran is preparing to educate his students personally, and as for the results, Duran is also looking forward to it.

So Duran suffered a tragedy. In just a few days, except for the ponytail female student, other students in the class collectively took a strike.

"Only after all the waves are washed away, heroes are revealed. Sally, I like you very much. I will definitely educate you as a hero who surpasses Satan!" Duran looked a little strange at this time.

Sally was just here to read, reading on her own, and she ignored Duran.

"Sally, 16 years old, lives in Satan City, and is a landlord in the suburbs. Not bad!" Duran nodded.

Sally ignored Duran, and Duran was not angry, "Okay, let's start class. In this chapter, we will talk about how to free our body from the constraints of gravity."

Sally raised her thick glasses and looked at Duran, "Teacher, please don't say anything I don't understand!"

"Well, I'll just say it again in words you can understand, let's learn how to fly today." Duran said, his body already slowly starting to float up, "Like it!"

At this moment, Sally finally showed a hint of surprise from her plain expression, but the book she fell in her hand showed that her inner surprise was not just the little bit on her face.

Duran floated in front of the blackboard, "This is what we will do in class in the future. You must learn to fly first."

"So possible?! Without the help of aircraft, humans can fly so much? It's impossible!" Sally repeated dumbly.

"Sally, you are too imaginative, why can't people fly?"

"People just can't fly!" Sally said stubbornly.

Duran shook his head, "But the fact is that humans can fly after training!"

“…”

"Okay, let's learn the principle of human flight now, it's Qi!"

"gas?"

"No mistake, Qi can make people do many things that violate physical common sense. Physics allows you to have an ordinary person's world, while Qi will allow you to enter a world that ordinary people cannot enter. A new and interesting world!"

"A world that violates physical common sense?" Sally obviously still didn't believe it.

"Yes, since Sally comes to my class, I will teach you. Correct your stiff thoughts. Okay, let me explain what anger is?"

Duran didn't care whether Sally could understand it or not, and explained it on his own. During this period, he also used his hands to show the luminous air bombs. Occasionally, he flew in the sky to do two difficult movements.

Saori didn't know how she came back to school. Her experience on this day made her feel a little overwhelmed. It made her parents worried.

"Saori, I said not to go to school. If the school doesn't change your teacher, don't go!"

"Dad, no, I'm going!"

"Why doesn't this child listen to others' advice? None of your classmates went there. What are you going to do? I see that your teacher will be replaced soon."

"Probably! But I won't go to school!"
Chapter completed!
