"It's impossible, this set of test questions is from the school's teaching and research team, and it stands to reason that there can't be anything wrong."

Qi Shu Nannan said, picked up the test paper, Qi Shu sorted out the mirror, turned to the first page of the test paper, and the seventh question was eye-catching!

Lu Xiao didn't talk nonsense, and walked onto the podium in the shocked eyes of the whole class.

Soon, Lu Xiao used beautiful block letters to write dense formulas on the blackboard.

After the solution steps were written step by step, Lu Xiao spoke: "Question 7, after the formula is decomposed, it seems that it is no longer decomposable, but in fact, through the equation, it can be decomposed again, on the blackboard, there are specific steps for my decomposition~~ After decomposing, we can see that there is more than one solution for X, in fact, there are two, one is -1, and the other is -19, but the four options of ABCD, except for the C option, which has a -1, the other options are not correctly solved, which is naturally not logical, so, This is a mistake. Choosing A, or B, or C, or D is wrong. ”

"This?"

Qi Shu carefully checked Lu Xiao's problem-solving process, and did not leave his mind for a moment.

After reading it, Qi Shu couldn't help but marvel, Lu Xiao's solution ideas and logic were completely correct, and there was no big problem with the solution steps, but in the end, X's solution, as Lu Xiao said, had two solutions, one was -1 and the other was -19.

This student is really amazing~

He can do math problems of such difficulty, and he is also the only student who can solve the final finale of this math test.

So, why did he only score 17 in mathematics?

The more Qi Shu thought about it, the more wrong it became, and then he remembered that Lu Xiao had only scored 17 points in this math test, not even 20 points.

No, the student who can analyze and solve these two problems must be a master of mathematics, certainly not an ordinary student, at least mathematics and Zhou are not much different~ But since he is a master of mathematics, how could he only score 17 points,

Although Lu Xiao said that he had no time to do other questions, this answer was obviously not logical, this math test, Qi Shu left two classes, calculated the time, nearly two hours, it is impossible to do what he said~ There is no time to do other questions, for what he said, there is only one situation that can be explained clearly! That is, he did it on purpose~

So did he do it on purpose?

Qi Shu looked at Lu Xiao, who was indifferent, and guessed, is there a possibility that he is indeed a hidden math master, on the surface, he is the first from the bottom, but in fact, he just doesn't want to expose his strength?

Thinking of this, Qi Shu looked at the podium and said with a little gentleness: "Student Lu Xiao has made great progress in mathematics this time, come down quickly." ”

Her tone is obviously different from usual~

Usually, she had never seen Lu Xiao with a straight face! The tone is also impatient and unaccustomed to it.

"It's just~" Not long after, Qi Shu changed his words again, "It's just, classmate Lu Xiao, next time, work hard and strive to score more than 20 points." ”

As soon as Qi Shu's words fell, all the students in the entire classroom of the eighth class of high school were boiling, and everyone laughed loudly, but this time the laughter was not teasing at all. It's just that the humor of the math teacher comes from the bottom of my heart~

Lu Xiao walked down, stopped talking, and looked indifferent.

His aura suddenly became very different from before. No more resignation, no more cringe!

He was only sitting in his seat, but the eyes of some of his classmates had quietly spread out on him!

Even Zhou Ye's tablemate Xu Ning noticed it~

You must know that in the past, Xu Ning was the same as Zhou, and he didn't care about that stupid boy.

But just now, when Xu Ning looked at Lu Xiao, she vaguely felt a different feeling, a bit similar to a deer bumping.

She looked at Zhou Ye, who was studying seriously, and tentatively spoke, wanting to arouse the topic of gossip, "Zhou Ye, have you noticed?" Lu Xiao seems to have changed a lot in the past few days. It's like a different person. ”

"Oh, really? I don't know! ”

Zhou on the side only replied lightly, without much waves, after replying, Zhou Ye continued to do the question, her eyes, indifferent and abnormal, reflecting her cold temperament, looked very arrogant!

She seems to care about everyone...

"Heiyu, your proposal is really fantastic, I never had such a limelight when I was a freshman in high school."

Lu Xiao sat down at this time, opened QQ with his mobile phone, found the chat dialog box with the black domain, and sent it by default.

Heiyu quickly replied: "Dear Mr. Lu Xiao, thank you for the compliment, but next, I will send you an English dialogue, please memorize, this will make your life seem very meaningful before your sixteenth birthday.

Lu Xiao replied, "My English level is very good, when I was 25 years old, I went to the UK once, outside the UK, I stayed for almost three years and three years, three years of living abroad, so that I can talk to foreigners, and I can also answer fluently, so, my English level is very OK, there is no need to send it to me." ”

Heiyu replied: "Dear Mr. Lu Xiao, although you are very good, Heiyu still recommends that you be able to memorize it proficiently, especially the most standard pronunciation of this paragraph in English, so that you can be prepared, you are a rigorous person, please continue to maintain your rigor." ”

"Okay!"

After tasting the sweetness once, Lu Xiao didn't think about it, so he replied happily!

Lu Xiao was just about to click the confirmation button, but before he could send it, the qq dialog box sent a long list of English ~ The title is, My high school campus, translated, it is my high school campus.

Below the heading, there is a long English version of the campus introduction.

The description in English is beautiful, like a poem.

Lu Xiao couldn't help but think, "What is the purpose of doing this, just to be a poet?" ”

But Lu Xiao didn't care.

Enter a sentence in the dialog box and receive it, and Lu Xiao began to listen carefully.

Qi Shu's math teaching ability is really first-class, Lu Xiao listened to her interesting problem-solving steps, and only felt comfortable, as if she was not boring learning, but enjoying.

When all the exercises were finished, Lu Xiao remembered a large part of the knowledge points in the book and was able to use them proficiently.

After all, Lu Xiao in 2022 is a person who has gone to college, and the knowledge of high school is naturally a small scene, and he only needs to be woken up a little to be able to get out of control!

Moreover, although Lu Xiao was a little worse in the first year of high school, after the second year of high school, he was a god-like existence, and he could only be reluctantly described as powerful.

…… After all the math papers were finished, the evening self-study was over.

This night, Lu Xiao wanted to be quiet.

Because he wanted to walk alone, Lu Xiao didn't get on Su Qian's electric car.

Lu Xiao walked out of the school and saw the lights flickering on both sides of the school gate!

At night, the street lamps are particularly soft and light, and bright street lamps stand on both sides of the street, projecting the light on the passers-by, reflecting the footprints of every passerby.

Looking at the street lamp in a daze, Lu Xiao's mind remembered the bits and pieces of high school. And, the person mentioned by Heiyu, but strangely, Lu Xiao remembered that there was such a person, but he forgot who it was.

Lu Xiao couldn't help but open the dialog box again, "I want to know, on that Baidu post, I said that it was because a girl came here, but I forgot who she was, Heiyu, can you tell me who she is?" ”

But soon, the news of the black domain made Lu Xiao think deeply

"I'm sorry, Dear Mr. Lu Xiao, this is about your contract, so the Black Domain has been modified, you have to find the answer yourself."
