Xu Feng's appearance is ordinary, and he belongs to the kind that he can't see when he is put in the crowd.

He is 1.75 meters tall, has a thin body, has a poor complexion, and is typically malnourished.

The one worn on the body is always the school uniform of Donghai No. 1 Middle School, which is very clean, so that people can't find the point of accusation.

The shoes are black cloth shoes, ten yuan a pair on the street, there are a lot of corner wool, and these shoes have been worn for a long time.

Several teaching directors looked at Xu Feng from top to bottom, they knew a little about this poor student who often slept in class because of his poor health, but they didn't expect him to dare to hit the teacher?

Is it because of the fast college entrance examination that some students are affected by the so-called college entrance examination syndrome?

If this is the case, for the sake of Mr. Wang's face, the punishment can be reduced as appropriate.

Several teaching directors were looking at Xu Feng, and Xu Feng was also observing them, but they only needed a glance.

The square-faced middle-aged man with glasses is Director Song, his liver is hot, his body is weak and weak, and the expression on his face can be seen that he is very unhappy to come here.

Director Zhao's body next to Director Song is even weaker, and at first glance, he consumed too much last night, and he doesn't know where he went.

The remaining two directors were middle-aged, wearing ordinary T-shirts, and their eyes did not change much when they looked at Xu Feng.

Liu Jing cleared her throat: "Several directors have arrived, and we will vote on the matter of expelling Xu Feng." ”

Wang Shishi shouted: "Director Liu, I will expel my student regardless of what happened, which school rule of Donghai No. 1 Middle School is this, I want to ask for advice." ”

Several directors saw Wang Shishi angry and looked over one after another.

Director Song pushed down his glasses: "Yes, Director Liu, as soon as you came, you called us to vote to expel Xu Feng, but we don't know what happened, and Director Shi Wenxin is not here." ”

"Director Liu, the expulsion of students is a big deal, and spreading it outside will also affect the reputation of the school. ”

"Let's talk about what happened. ”

Liu Jing's face turned red: "He dislocated several classmates, and even I went to find him and was dislocated, isn't this enough to be expelled?"

Director Song looked at Xu Feng: "Is there such a thing as Xu Feng?"

Wang Shishi was a little worried, she went to the infirmary to ask, it was indeed a few students who had dislocated, but it was not clear whether Liu Jing had dislocated.

Xu Feng's expression was calm: "It has nothing to do with me, they dislocated it themselves." Several directors can watch the surveillance video, and I believe that several directors will have results after watching it. ”

Whether it was yesterday's surveillance video or today's, he was justified in self-defense.

Especially about Liu Jing's part, I believe that several directors will be very angry when they see it.

If the video of beating students like this spreads, what will happen to the reputation of the school.

Xu Feng was not in a hurry at all, but Liu Jing was in a hurry.

Surveillance footage......

How did he not think of it.

Director Song made a phone call, and the security department quickly sent the surveillance video to the teaching office, and the USB flash drive was inserted into the computer to play the surveillance video of Class 9.

After watching the video, the faces of the five directors, including Liu Jing, were ugly.

Liu Jing's nephew, Liu Hao, actually took the lead in school bullying, if it weren't for Xu Feng's wit, it would not be difficult to imagine the consequences.

Several people thought of the suspected incident of a senior high school student jumping into a lake reported by the "Donghai Morning Post", and their faces became even more ugly.

Liu Hao was beaten, Liu Jing, who was an uncle, went to find trouble, looked at the slap in the surveillance video, how hard the fan was, if ordinary students were not allowed to be disabled?

That's their school teaching colleagues!

Director Song pushed his glasses, cleared his throat, and pointed to the scene of the slap: "Director Liu, you need to give us an explanation for this matter." ”

Liu Jing's face was pale, it was his hand that moved first, how do you want him to explain?

What else is there to explain?

"Director, you saw it, from beginning to end, you hit me first. Xu Feng was polite and made Liu Jing's lungs blow up.

"Director Liu, the student who hit me in Class 9 must give an explanation. Wang Shishi tore her face directly, if she didn't give an explanation and made trouble to the principal, she would take care of it.

Damn little bastard!

Bastard!

Xu Feng's expression was calm, and he saw that the situation was almost over, and said, "A few teachers, can I go back to the classroom to study first?"

Director Song nodded: "Well, there's nothing for you here, go back." It's almost time to take the college entrance examination, so hurry up. ”

Xu Feng withdrew from the teaching office and closed the door by the way.

What happens next inside has nothing to do with him.

The only thing I know is that the teaching office of Donghai No. 1 Middle School is sometimes even more powerful than the principal's office.

With great power comes great responsibility, and Liu Jing's personal vendetta against the student communiqué touched the foundation of the teaching office.

If you don't deal with it in time, it's a big trouble.

Solve the trouble, whether it is Liu Hao, or Song Qing, Liu Xun, I saw that Xu Feng basically chose to take a detour.

Xu Feng is so evil, even the teaching director Liu Jing was beaten, not to mention them?

"It's better to learn the lesson. ”

Xu Feng continued to do the question, and he didn't bother to pay attention to these inconsequential ants.

The knowledge of physics is almost mastered.

Next up is chemistry.

I used to be keen on studying for the college entrance examination, but as my studies deepened, Xu Feng, who fused soul memories, became more and more interested in scientific research on the earth.

Mathematics can involve the laws of heaven, physics and chemistry can go deep into the origin of matter, and biology is exploring the complex genetic code of astronomy, all of which are beyond the reach of the Yanghe Star Immortal Cultivation Realm.

Kong Sheng once said that if you are a threesome, you must have my teacher.

Xu Feng originally thought that these were just jokes of the saint, and as for the story of the saint listening to the two children arguing about the day, it was just to spread it for the convenience of proselytizing.

But combined with the memories of both lives, he was convinced that these were true.

The wisdom of mortals is not to be taken lightly.

According to the original plan, Xu Feng was going to take the university entrance examination, fulfill the wishes of his mother and predecessor, and then start to pursue the Great Dao and return to the peak of the Immortal Dao.

Now, he's starting to look forward to college.

Well, go ahead and do the question.

Time passed day by day.

Xu Feng practiced, read, and did questions every day.

At a fixed time every day, you can see Xu Feng coming out.

At a fixed location every day, you can see Xu Feng passing by.

Fixed ...... every day

It was Lin Xiao, the class leader, who first discovered this phenomenon, because every time she opened the classroom door, she would see Xu Feng entering every second.

A fixed time is nothing, every time, and that's curious enough.

Lin Xiao decided to help Xu Feng, after all, pretending to review every day would not have any effect.

In the morning, Xu Feng arrived on time.

Open chemistry for three or five years to start doing questions.

After combing through the relevant knowledge points last night, these questions have become very simple.

Well?

After only a few questions, Xu Feng found a person standing next to him.

It was squad leader Lin Xiao.

Lin Xiao is a good girl, she has helped her predecessor a few times, and Xu Feng has a good impression of her.

"Is there something wrong?" Xu Feng stopped writing.

Lin Xiao stared at Xu Feng's answer and said, "Xu Feng, you shouldn't give up on yourself, even if it's for yourself, you can always get a few more points in the college entrance examination and change your destiny." ”

Lin Xiao took a deep breath, his face slightly red.

She hadn't said that yet.

Xu Feng smiled: "You may have misunderstood something." ”

"Misunderstanding?"

"You can check the answers and see if I'm right. ”

Lin Xiaohu was suspicious, took the book and compared the answers, and found that Xu Feng wrote correctly: "You copy the answers?"

Copying answers is worse than scribbling them out.

She didn't want to be so suspicious.

Xu Feng shook his head with a smile.

For such a simple question, do you still need to copy the answer?

You can write the answer with your eyes closed.

"If you can't say it, you may not believe it, if there are any questions that you can't do, you can ask me, and I will help you solve them. ”

Xu Feng said very seriously, sometimes it is better to express justification with actions.

Lin Xiao was stunned for a moment and looked at Xu Feng for two seconds.

"Good. ”

She happened to have a problem with a question, which was a press-paper question about the principle of using adsorbents to remove the polluting element As from factory and mine wastewater.

"Look at this question. ”

Lin Xiao handed the test paper to Xu Feng and pointed to the question and said.

She has spent fifteen minutes on this question, and she can only solve two small problems so far, and she has no clue about the follow-up.

In the college entrance examination, there will not be so much time for her to think, a big question can not be solved, it means losing points, and once you lose points, the consequences are hard to imagine.

Xu Feng glanced at it and had the answer in his heart: "The answer to the first small question is carbon dioxide, and the reason is that the alkaline solution absorbs carbon dioxide in the air. ”

Lin Xiao nodded: "Well, the first small question is to send points." ”

Xu Feng took a pen and wrote the chemical reaction equation on the white paper beside him: "This is the ion equation of the main reaction, you can verify it." ”

The equation was the same as what she wrote, Lin Xiao was a little surprised, Xu Feng wrote the equation too fast.

What surprised her even more happened, Xu Feng swiped a few times and wrote out the follow-up answers: "This is the answer, you can compare it." ”

"Referring to the curve, between PH7~9, with the increase of pH, the negative charge on the surface of adsorbent X will increase, and the electrostatic repulsion will increase by ......"

"After solving the previous problem, the measures that can be taken by high adsorbent X on the removal effect of trivalent As also come out, adding oxidant to convert trivalent As into pentavalent As. ”

"Okay, any more questions?"

To put it bluntly, this question is about ionization equilibrium and the calculation of ionization equilibrium constants, and the answer is clear and knowable without removing the huge and complicated description.

Lin Xiao looked at the answer on the paper, as if the answer was indeed what he said.

In the spirit of seeking verification, Lin Xiao checked the answer, and it was exactly the same as what Xu Feng said.

It's not scientific!
