"Then, from this diagram, we can know that when the ball is shot at a speed of 40 m/s in the direction of a 30-degree angle to the ground, the flight path of the ball will be a parabola, and if the air resistance is not considered, then the relationship between the flight altitude H and the flight time T of the ball is ........."

The classroom was silent, except for the sound of squareness and the "click" of chalk. However, the students below did not listen to the lecture with peace of mind, on the contrary, they exchanged glances with each other uneasily, looking at Fang Zheng standing on the podium for a while, and looking at the girl sitting on the chair for a while.

Although they didn't speak, the eyes in each other's eyes revealed enough content.

"Hirai-san's won't be like before........."

"Who knows, after all, the teachers of the first few classes are about to cry because of her."

"But Mr. Fangzheng's lecture is very easy to understand, so Hirai-san's opinion shouldn't be ........."

Thinking of the situation of the previous courses, everyone couldn't help but get nervous. They don't know why today's Hirai Yuan suddenly went against the norm and became this aggressive look. But to be honest, the current atmosphere made them feel more nervous and uneasy than the exam, and on the one hand, they were worried that Fang Zheng would also question the girl like the teachers in the previous classes. At the same time, I am worried that the girl will contradict the teacher again like before.

After all, unlike those previous teachers, Fang Zheng is the tutor of this class, and he has a gentle temperament, is handsome, and is quite trusted and popular with students in all aspects. The teachers in the past were either too old-fashioned or unpopular. But now......... They didn't want to see Fang Zheng quarrel with Pingjing Yuan again, after all, he was a mentor, and if he got angry, then everyone would be unlucky.

"So, please turn to page 23 of the textbook."

Fang Zheng, who had finished writing the board book, turned his head and looked at the people in front of him, then he raised his eyebrows and looked at the girl who was sitting motionless on the chair with his hands in his arms.

"Hirai-san, why don't you open the textbook?"

Here it comes!

Hearing this, the others immediately perked up and stared at the scene in front of them uneasily. Sure enough, after hearing Fang Zheng's inquiry, the girl snorted lightly.

"I really don't know how you became a teacher, you can solve problems with a simpler formula, but you have to follow the content of the textbook at a glance. And, isn't this a waste of time? Teaching students like you is simply lazy! ”

Wow............

Hearing the girl's merciless reprimand, everyone gasped. And the short-haired girl sitting not far from the girl's side looked at her uneasily, wanting to open her mouth to say something. But.........

"So what?"

To everyone's surprise, Fang Zheng on the podium was not as annoyed and angry as the teachers before him, on the contrary, he was smiling and looking very calm.

"I think you're mistaken, Hirai-san, the so-called teacher, first of all, is to teach the knowledge to the students clearly, and people can only run after they learn to walk. This is the school, and I'm teaching the whole class, not just you. And everyone's comprehension ability is different, and for me, the first thing to make sure is that every student is able to grasp the knowledge before moving on to other things. ”

As he spoke, Fang Zheng reached out and knocked on the blackboard.

"Please don't forget, the exam is the content of the textbook, and mastering it at a glance will not make you deduct points in the exam. Maybe it's boring, but ......... Life is not always easy. ”

Hearing this, the girl's expression became more and more unfriendly.

"Do you want to do anything as long as you can pass the exam?"

"It's true for now, only by passing the exam will you be able to get a high score, go on to university, and decide your future......... Scores determine the future, and that's all we do. This is the rule, each circle has its own rules, maybe it is very impersonal, it can be cruel, but ......... It's the rule. Adapt to it, change it, it's as simple as that. ”

As he spoke, Fang Zheng looked at the girl in front of him.

"You know what I mean, Hirai-san. Maybe these lessons are easier for you, but unfortunately, I'm not your tutor and don't need to follow your pace. Also, whatever you want to do, please open the textbook, this is a minimum of respect for the teacher. ”

“…………………”

Hearing this, the girl fell silent, and the rest of the class watched her nervously. After a few moments, the girl snorted, and then silently opened the textbook in front of her.

"Good."

Seeing this scene, Fang Zheng nodded secretly. It's just a second-year-old girl, and you're afraid that I won't be able to cure you? Don't look at whose territory this is, and want to find a sense of existence here? Let's go home and go to sleep.

"So, let's open the textbook, page 23."

I don't know if Fang Zheng persuaded Xana, at least after that, the girl didn't make trouble again, just stared at her textbook silently. I don't know if it's a daze or a distraction, but anyway, the originally tense and suffocating atmosphere in the classroom has finally begun to ease. And the other students in the class naturally admired Fangzheng more and more.

In such an atmosphere, the day's study time passed quickly, and as the bell rang for the end of class, the students who were already ready to move also rushed out of the classroom with cheers. And Xana also picked up her schoolbag without saying a word, mixed in the crowd and turned to leave.

That's right, obedient little ghosts are cute.

Looking at the figure of Xia Na leaving, Fang Zheng smiled slightly, and just as he packed up the things on the podium and was about to turn around and go out, suddenly, a voice sounded in Fang Zheng's ears.

"That's, that'......... Mr. Fang Zheng ........."

"Huh?"

Hearing this voice, Fang Zheng turned his head to look, only to see that not far from him, a girl with short brown hair was standing there, looking at him uneasily.

"What's the matter? Yoshida-san? ”

What appeared in front of Fangzheng's eyes was none other than his student Kazumi Yoshida. This is also one of the high-level beauties in the class.,Like the setting in many Japanese animations.,Beautiful and beautiful.,Gentle and kind.,Very popular.......... Forget it, it's all this routine anyway.

"That's right......... That ........."

Facing Fangzheng, Yoshida Kazumi obviously looked a little cramped, she lowered her head, hesitated for a moment, and then spoke.

"Please don't be angry with Xiaoyuan, I don't think she did it on purpose, she just encountered something so she wasn't in a good mood........."

"I'm not angry."

Fang Zheng waved his hand, and then he also remembered that the Yoshida Kazumi in front of him seemed to be friends with Hirai Yuan......... Well, forget it, although it's a little cruel, but there are some things, and it's better to not know.

"It's just a little accident, nothing to worry about. On the other hand, Yoshida-san, it's almost time for you to leave school. It's getting late, so be careful on the way home. ”

"Ah, yes, I got ......!"

Hearing Fang Zheng's answer, a reassuring smile appeared on Yoshida Kazumi's face, and she bowed respectfully to Fang Zheng, and then planned to leave the classroom.

"Then I'll go, and the teacher will ......... again"

However, the girl's words were not finished.

Because at this very moment, the bright red world came again, freezing everything.

Blocked!

Looking at the world in front of him as if time had stopped, Fang Zheng's face suddenly sank, and at this moment, behind him, a deck of playing cards appeared out of thin air, shooting towards Fang Zheng like an arrow!

"Whoosh!!"

And just as these cards were about to hit the center, several magical rays of light appeared one by one, followed by a violent explosion, and the flames appeared, but they were instantly resisted by the magic barrier that shone with a clear blue light.

"Compared to the Fire Mist Warriors, the Red World seems to be more brutal."

Glancing at the white flames blocked by the magic barrier, Fang Zheng snorted coldly, and then he pulled out the Broken Sky Sword with his backhand and shook it suddenly!

The tyrannical sword aura swept through the classroom like a scimitar and slashed at the playing cards in front of him. And the deck of playing cards, which kept spinning, seemed to sense the danger coming. Suddenly it turned into a circle, as if it was guarding something. Immediately after that, the roaring sword qi collided heavily with the spinning playing cards.

"Boom, boom!!"

The scorching flames scattered and flew in all directions, and the originally neat classroom was now a mess, and the originally neatly arranged desks and chairs were swept up, twisted, torn, and reduced to broken pieces by the storm.

"Ah———!!h

With a scream, the flying playing cards dispersed, and then a broken puppet burst out of the smoke and rushed towards the gap in the wall.

Still want to run?

Looking at the figure in front of him, Fang Zheng snorted coldly, and then he stretched out his hand and pointed forward. Dozens of glowing magic missiles suddenly burst out from Fang Zheng's fingertips, whistling towards the tattered doll.

"No......... Master!! ”

Just as the magic missile was about to blow the puppet to pieces, a white shadow suddenly appeared out of thin air, blocking the puppet's face. I saw that the figure waved his right hand slightly, and the magic missile that flew out suddenly exploded in the air and disappeared without a trace.

Immediately after, a voice rang out.

"So you're the human who took the treasure......... I don't see it, you really have some skills. ”

With this voice, a man in a white suit appeared in front of Fang Zheng.
