"Huhuhuhuhu......"

Brother Tiger pressed one hand to his chest, his heart was beating like a machine gun, and he felt like he was about to explode.

At that moment just now, he really thought he was going to die!

"Look."

The physics teacher patted him on the shoulder, pointed his finger at the broken chalk behind him, and said, "Isn't the bullet crooked?" ”

Students: "......"

What else can they say about this?

The Force turned a corner, and I couldn't afford to mess with it.

Cheng Hai and Cheng Yi glanced at each other, and the latter nodded knowingly.

This ghost's spiritual power can keep up with bullets, and only Yiyi can deal with him in the field.

Unless he transforms.

"The teacher is right, I have learned, and I will go and match Newton." Tiger Brother shivered.

"You can teach."

The physics teacher nodded in satisfaction and turned to the podium.

"It seems that you have mastered today's knowledge points, and then I will test you in my debut."

"Question?"

As soon as they heard these two words, everyone cried and mourned.

The questions from the teachers in this school will definitely not be serious.

I saw the physics teacher take a rope and tie one end to a fixed window bar next to the classroom wall.

"Everybody's looking at it."

The physics teacher straightened the rope and said to the crowd, "I told you about the principle of levers earlier, and now it's time to use it." ”

The crowd sat down and took out scratch paper.

"The known fixed fulcrum is on the wall at a height of 0.5 meters, with a 1-meter rope tied to one end of it, and I hold the other end. Excuse me, if I step on the middle of the rope, how much force do I have to lift myself up? ”

Brother Tiger: "??? ”

Ji Youzhu: "??? ”

Long Yiyang: "??? ”

Li Feng: "......" (in the process of calculation)

Shen Temeow lifted himself up, Wudang Tiyunzong?

This problem is as outrageous as the genius logic of putting a powerful magnet at the hook of a crane to achieve perpetual motion, and Archimedes would tear him apart in a matter of minutes in China.

So, they all looked at Cheng Hai.

That's the kind of question he can answer.

Sensing everyone's gaze, the physics teacher also looked at him and asked, "Can this student answer?" ”

Cheng Hai thought for a while and said, "It's very simple, half of your weight." ”

"What do you mean by that?" The physics teacher frowned.

Although he didn't know what his answer was, Cheng Hai's answer was obviously different from what he thought.

"Simplicity, practice tests the truth."

Cheng Hai gave Cheng Yiyi a look, and Cheng Yiyi stepped forward to pick up one end of the rope and stepped on it in the middle, and then mentioned it......

She levitated.

Isn't it the Force, when no one knows it?

Physics Teacher: "......"

Brother Tiger: "......"

Ji Youzhu: "......"

Okay, we're in charge of shocking the audience, you show.

Cheng Hai looked at the end of the rope and said, "It seems that if you want to know the answer, you have to add a force tester." ”

The physics teacher wiped his sweat and said embarrassedly: "This classmate is doing a good job......

At this moment, the ceiling fan overhead suddenly rattled and burst into sparks.

Cheng Yi waved a small hand, and the people centered on the physics teacher, the tables and chairs parted outward.

Hearing the sound of "duang", the old fan broke with a bang and smashed to the ground.

The students stood up from the chaos and gasped.

The physics teacher's neck was cut by a fan blade by a dozen centimeters, and he stood in place.

"Are you alright?" Ji Youzhu asked worriedly.

The crowd shouted that they were safe.

"It's really hard to learn."

The physics teacher pulled the fan blade out of his neck and said dissatisfiedly: "Shouldn't we think about why this fan fell down at this time?" ”

Students: "......"

Isn't it just in disrepair and broken, do you still want us to answer because of gravity?

"In that case, I'll give you another question to help you deepen your impression." Seeing that the students were unconscious, the physics teacher sighed and turned around to write on the blackboard.

This time, the topic is more normal.

It's a free-fall problem: given that one floor is five meters high and has an air friction coefficient of 1, how long does it take for a person to jump from the fourth floor?

The students present are all from universities, and this kind of basic question is not difficult for them.

The only two exceptions are Cheng Hai and Brother Hu.

They have been out of society for many years, and although they still remember the principles, they have long forgotten the formulas and so on.

If the sea is not tight, he dropped a pen from mid-air, and the forbidden eye directly calculated the formula.

The person who really has a headache is actually only Brother Hu.

Five minutes later, everyone handed in their answers.

"What's the matter with you, little brother?"

The physics teacher looked puzzled.

"I ...... I don't remember the formula. Brother Tiger said.

"Don't remember? That's the basics! ”

A black gas came out from behind the physics teacher, and his elegant face gradually became hideous.

Brother Hu had a bad premonition in his heart, and hurriedly looked at Cheng Hai.

It's just that Cheng Hai didn't make any moves.

"Don't you save him?" Cheng Yiyi asked suspiciously.

In her eyes, Cheng Hai seems to like to be "nosy".

Cheng Hai shook his head and said, "I'll teach you the second lesson later, what kind of person can be killed." ”

Ji Youzhu beside her was taken aback, she looked at Cheng Yitian's innocent little face, and her eyes were full of incredulity.

Is this kind of thing really suitable for teaching such a young child?

"Hmm."

Cheng Yi nodded.

Since that conversation with Fan Jiang, she has been prepared for this.

Especially after eating the female ghost, she can already feel the restlessness in her heart.

Very bad!

"Teacher...... I was wrong, I was wrong! I will definitely study hard in the future! ”

The two were chatting, and Brother Tiger had been picked up by the physics teacher and walked towards the outside of the classroom.

This guy likes to test crooked theories with practice the most.

"Let's go, get ready."

Cheng Hai took Cheng Yiyi and walked out.

The students did not dare to stay alone in the classroom, so they had to follow.

"Teacher, I was really wrong, please let me go......"

Brother Tiger was suspended in the air by an invisible force, and his body struggled desperately, like a drowning man who couldn't swim, unable to move for half a minute.

"Will you correct it?" The physics teacher said coldly.

At this moment, the evil aura exuded from his body had already made Cheng Hai feel cold.

"Yes, yes, yes! You can tell me to do anything! ”

Under his feet is forty meters in the air, how dare Brother Tiger not agree.

"Good."

The physics teacher nodded and said, "Then from now on, you can calculate the time of landing." ”

"Huh?"

As soon as Brother Tiger asked, he felt that his body was loosened in vain, and the feeling of losing control instantly spread to the depths of his mind.

"No—to—ah—"

The terrible screams were stretched out in the night sky, and a tall man was smashed into meat sauce.
