It's another day for the broken vase

On the next Saturday, during the whole day of self-study class, the guests still had to go to the podium to stare at the students. Before the bell rang, Lu Qi and Feng Qianxing sat down on the podium calmly under the resentful eyes of Class 20er.Seeing the displeasure on everyone's faces, Feng Qianxing "kindly" reminded: "It's a violation of discipline to look up."

Class 20: =dish=!Why did they think that the two of them got along very well before!It's obviously so difficult!

The students reluctantly lowered their heads to do their homework, thinking angrily, thinking back then, how could their class shut up before the class bell rang!

On the podium, Lu Qi took out a five-three set, and Feng Qianxing asked in a low voice, "You should know all these questions, why are you still doing it?"

"The reason why the college entrance examination questions are college entrance examination questions is that they are classics." Lu Qi flicked the pages of the book, "Now I am compiling the questions based on the test points of the college entrance examination questions."

Feng Qianxing was shocked: "Edit title??"

"Hush," Lu Qi motioned him to lower his voice, "Yes, I'm going to make up questions for the common weaknesses of students in No. [-] Middle School."

Feng Qianxing was still shocked: "This, this is too nb!"

"Hush, the bell is about to ring, don't talk."

As soon as Lu Qi finished speaking, the class bell rang, and the teacher came and wandered around twice before slowly leaving again.

After the classroom fell silent, Lu Qi and Feng Qianxing focused on doing their own things. They thought they would sit down peacefully all this time, but they didn't expect an uninvited guest to come after half a class.

He has the impression that this classmate is the expectation of all the teachers in class 20, the golden thigh of all the scumbags in class 20, the No.1 in the class, the top [-] in the grade, he is considered a top student.

What was even more impressive was that he only wrote down the name of this classmate on the blackboard last night.

I saw Jin Da...Xueba classmate holding a piece of draft paper in his hand, with a gloomy face and a mocking arc on his mouth, slowly walked up to the podium, and said to Lu Qi: "After watching yesterday's variety show, I know Your score in the entrance exam is very high, so I have a question to ask you."

Feng Qianxing who was on the side asked Lu Qi in a low voice: "Can I still ask questions in the self-study class?"

"Yes." Lu Qi said, and then looked up at Xueba, calmly, "What question do you want to ask?"

Xueba glanced down at the five-san in Lu Qi's hand, and raised the corner of his mouth—low, only brushing five-san is too low. Xueba put the draft paper in his hand in front of Lu Qi, and said, "This is me. I wrote down a question I saw yesterday on paper, I think Lu Qi, since you can sit here on behalf of the teacher, you must be capable, right?"

"Do you want me to answer?" Lu Qi didn't rush to agree, but asked instead, "Then did you ask anyone else?"

Xueba was stunned for a moment, as if he didn't understand: "Ask other people?"

"Yes."

Xueba was puzzled and said, "I don't even know how to do it, can other people do it?"

These words were a bit ironic, but Xueba didn't seem to realize that these words had unknowingly hurt the young hearts of other students.

Lu Qi calmly glanced at the classmates who were faintly agitated because of the words of Xueba, and said: "You can't say that, everyone has their own strengths, you may specialize in a certain subject, and you are better than others. It’s amazing, but if you can’t do this question, it doesn’t mean that others won’t.”

These words made the faces of other high school masters and many scumbags who were originally sullen look a little pale, and the eyes they looked at Lu Qi softened a lot.

Feng Qianxing clicked his tongue and looked at Lu Qi who had a predictable expression - this guy really never forgets to play with people's hearts.

Xueba became impatient: "Anyway, I don't know how to do it, and neither do others, so you can just say whether you can do it."

Lu Qi just took the draft paper, and said without talking too much: "I'm not sure if it will be."

Feng Qianxing looked at Lu Qi with a humble tone, but his expression was determined to win.

Lu Qi glanced at the topic written on the draft paper, his expression did not change, but Feng Qianxing could see that his originally lazy eyes became serious.

"Is it difficult?" Feng Qianxing touched Lu Qi's arm and gave him a look.

Lu Qi shook his head slightly to indicate that there is no need to worry, and after a quick scan of the question, he picked up the pen and began to answer.

Xueba's expression was originally a little mocking, but seeing Lu Qi's faster and faster writing speed, his expression became serious, and gradually became shocked again.

Feng Qianxing was curious why the expressions of these two people had changed in this way, so he leaned over to look over, and saw that the title above was like this:

"For an ordered integer pair (x, y), if the greatest common divisor of x and y is 1, then the point corresponding to the number pair (x, y) is called the primitive lattice point, given a finite primitive lattice Point set S, prove that there are positive integers n and integers a0, a1,...an, so that for each (x, y) of point set S, there are..."

Feng Qianxing: @[email protected]

The more Feng Qianxing looked at it, the more confused he became. He knew every word, but why didn't he recognize the combination? ?

Is this high school knowledge? ?Is it that he hasn't learned yet or has a low IQ? ?

Looking at Lu Qi again, he moved his pen like flying, and he has already written five or six lines in the answer area.

Feng Qianxing suddenly fell into deep doubts about himself, and was about to close his eyes for a while, when he just sat back in his seat, he bumped into something. At that time, there were five or six students who were usually noisy and troublesome, and they were all staring at the draft paper.Feng Qianxing originally wanted them to break up quickly, but their expressions subtly pleased Feng Qianxing, and Feng Qianxing proudly puffed out his chest, thinking that my boyfriend is just that good!

After Lu Qi finished writing the process briefly, he said to Xueba: "My process is relatively simple, so let me explain it to you carefully. Let's first summarize the number of elements in the point set S. If S=1, set S={ (x0, y0)}, and then according to Bezout's theorem, it is known that there is an integer ab such that ax0by0=1, taking the homogeneous integer coefficient polynomial..."

Listening to Lu Qi's eloquent and eloquent explanation, everyone including Xueba was dumbfounded. After finishing speaking, Lu Qi asked, "Did I explain clearly?"

... what s what b? ? ?

Xueba got stuck, and said after a while: "... I understand, I understand."

"That's good." Lu Qi handed the draft paper back to him with a smile, and when Xueba was about to take it, Zeng Yuhang suddenly said: "Hey Xueba, since you know it, why don't you tell us about it? We don't know yet."

Xueba was stunned: "...what?"

With Zeng Yuhang at the beginning, several other students booed one after another: "That's right, tell us about it!"

Xueba began to sweat on his forehead - he really doesn't know how to solve this problem, but he didn't intend to come here to solve the problem!He thought he was pampered and pampered by so many teachers, but since these two celebrities came, the teachers took care of them more, which made him itch with hatred.Especially yesterday when he was named in front of the whole class, it can be said that he lost the face of the boss. Today, Lu Qi came to see him being slapped in the face in front of the whole country, but he never expected to be slapped in the face instead!Moreover, these scumbags dare to add insult to injury? ?

Lu Qi talks fast and writes fast, who can keep up with his train of thought!But I just said that I understand it, and now I can't understand it, wouldn't it be... even more embarrassing! ?

Xueba's face turned pale, Zeng Yuhang complacently exchanged glances with his fellow students, and when he was about to take advantage of the victory to completely discredit Xueba, Lu Qi picked up his pen again and said, "The first This one is really troublesome and hard to remember, but it’s okay, I have another solution..."

Why?Is there a second solution?

Xueba's eyes lit up, but then he was deeply grateful to Lu Qi - Lu Qi's second solution was really timely!Just to resolve the embarrassing situation right now!

So for the next 10 minutes, Xueba was forced to listen to the second solution during the entire process of petrification. When Lu Qi wanted to talk about the third solution, he finally came to his senses and waved his hands again and again: "No, no, no, no! , I already know it! Thank you!"

With a flushed face, the bully snatched the draft paper and ran away, leaving the scumbags with regrets on their faces—hey, it's a pity that I can't see being slapped in the face.

The good show didn't come to fruition, a few people dispersed in a hurry, and the students who watched the excitement below plunged into the sea of ​​questions again full of regret.

After thinking for a while, Lu Qi got up and walked to the podium, called the video camera brother into the corridor, and said in a low voice, "Excuse me, can this part be cut?"

The big cameraman was surprised: "Why? This footage will be very popular, right?"

"Hotness means controversy," Lu Qi said, "Besides, they don't have to bear the burden. It's our arrival that broke the peace, so I hope you can seriously consider my request."

The camera brother's child is also in school. Thinking about it carefully, indeed, if it were him, he would not be willing to let his child be popular in this way.It would be a pity to just throw away this piece of material... The camera brother hesitated for a moment, and said: "I can't make the decision, but I will talk to the post-production side."

Lu Qi smiled and nodded in thanks: "Thank you very much."

This made the big cameraman feel embarrassed, he scratched his head, and said, "You're welcome, I can't guarantee..."

After negotiating with the camera brother, Lu Qi returned to the podium.

Feng Qianxing, who watched the whole process, had to sigh and say to Lu Qi, "The means are really good." First, he frustrated the arrogance of the top students, and gave the top students a breath of relief, but he didn't hit all the top students. He rescued Xueba in an embarrassing situation, and even begged the cameraman to delete this paragraph. It was really thoughtful to preserve Xueba's fragile self-esteem, which is not unreasonable.

Listening to Feng Qianxing's constant tsk-tsk admiration, Lu Qi calmly sorted out the unfinished exercise book in his hand, and continued to bow his head to compile the questions, hiding his achievements and fame deeply.
