After listening to the trial, Gu Yu didn't stay outside for long, and went back to the dormitory.

took out the mobile phone, only to find that there were a few more missed calls to the familiar number.

Every other hour, five minutes of ringing, persistent, and very respectful.

Gu Yu coughed, pressed the callback button, and the voice that came over there was a little impatient and eager:

"Professor?"

Gu Yu: "...... What's wrong? ”

Zhang Fei coughed a few times and controlled his tone:

"We've already done the contest questions you sent."

Gu Yu: "Hmm. ”

Gu Yu: "Found a mistake?" I'll change it. ”

Zhang Fei: "........"

Not really.

Seriously, if it weren't for the solution provided by the professor, there was really a method that could be solved only by relying on the knowledge of the competition in middle school, they would have to doubt that the problem taught was done for them.

With so many people in the School of Mathematics, more than 50 professors up and down, it took an hour to finish the question, and then it took three days to understand the answer.

I can't say it's difficult, I can only say that it's too flexible.

These questions seem simple, but the ideas are very novel, and the methods of solving the problems are also very varied, Zhang Fei bets that if this question is given to the mathematics competition groups in various provinces, the proposition teacher will be speechless.

If you give a problem to the professors of the School of Mathematics, you should give it to the students who are competing......

If nothing else, you may not even pass the highest score.

Although, Zhang Fei still wiped the sweat on his forehead and said cautiously:

"Professor, there is nothing wrong with this question, it's just that it's ...... difficult."

Gu Yu, who has already reduced a lot of difficulty according to the competition books on the market: "........"

Before she sent it, she thought it might be a little easier.....

Gu Yu, who had misestimated, was silent for a moment: "I have a new one?" ”

Zhang Fei naturally waved his hand subconsciously: "No, no, no!" ”

The professor's time is so precious, and they don't dare to use it to bother the professor again and again.

In fact, he made this call to ask for advice:

"The idea on our side is that the teachers from the School of Mathematics will change the questions again, make it simpler, and put it in the finals, do you think it's okay?"

Gu Yu didn't have any opinions, agreed, paused slightly, and asked, "Have you read the answer?" ”

She obviously provided three ideas for solving the problem, which should not be difficult.

Zhang Fei: "......."

To be honest, they also realized that these questions are so advanced and there are so many solutions.....

Zhang Fei continued to wipe his sweat: "I watched." ”

The meaning of this is that it is really difficult.

Gu Yu: "......."

All right.

Although he felt a little tired of the professor, the person over there still hesitated to speak: "I don't know the professor, is there any other solution to the problem?" ”

No way, the professors of the School of Mathematics are some problem-solving maniacs, after seeing the professor's problem-solving method, they studied sleeplessly for three days, and after the study, they urged him to call and ask for other problem-solving ideas, Zhang Fei had this question.

Gu Yu moved the mouse with one hand: "There are two more, will I send them to you later?" ”

Zhang Fei: "......."

Two, two? Each question?

The caller was stunned for a moment.

He thought he was ...... I thought that those questions were at most one or two different ways to solve the problems, but I didn't expect the professor to reserve other solution ideas, two for each question???

Gu Yu saw that he didn't speak, and said, "Not enough?" ”

Zhang Fei immediately came back to his senses: "Enough is enough!" ”

The scholar, who has always been rigorous and self-controlled, was busy wiping his sweat and said in a respectful tone: "Excuse me, professor. ”

Gu Yu tapped the keyboard with one hand: "It's okay." ”

The research institute of Beijing University helped her a lot, and it was just a problem that was within her ability.

Everyone in the research institute was flattered, and when Zhang Fei hung up the phone, they immediately rushed up:

"What did the professor say?"

"Is there any other solution?"

"Is the professor busy? If you have a chance, can you find her to come up with a set of questions for us again? ”

"Do professors still need books from the Kyoto University Library? I can apply with the school ......"

"Professor.......

Zhang Fei coughed a few times, and tried to narrate in a steady tone:

"The professor agreed to let us change the question to reduce the difficulty, and ......"

He paused, his tone of awe: "Two additional ideas for solving the problem are provided. ”

.......

Lu Qingqing caused trouble, and stayed at home for a few weeks before he appeared in the classroom of the first class with his schoolbag on his back.

Although a few weeks have passed since the apology at the flag-raising ceremony, there are not a few classmates who feel that they have been fooled, and there are not a few people who remember it very clearly.

Lu lightly bit his lip, his fingers tightly gripping the strap of his schoolbag, a little embarrassed.

This kind of emotion reached its peak when he saw Qu Wenyu without even looking at her, and passed by her directly.

There seems to be a lot of chaos in my ears, constantly amplifying gossip:

"Is that her?"

"It's her, slandering Lu Yu to push people......"

"Oh my God, it's so vicious......."

"Harm, if you want me to say, if I were Lu Yu, I would hand over the evidence and let her drop out of school."

"Be quiet, be careful when people say you've pushed ......."

......

Lu Qingqing held back tears and resentment, and walked into the classroom of the first class with some inflexibility in his legs and feet.

The classroom where the topic was still discussed in a whisper was quiet.

Lu Qingqing was even more annoyed, sat down next to Lu Ziyu, looked sideways, and his hand was held by Lu Ziyu.

The tip of her nose instantly soured.

Lu Ziyu sounded with an unbearable voice: "Light, how can you do this......"

It seemed that seeing her eyes red, Lu Ziyu stopped: "No matter what, light, you must learn a lesson, you can't do it anymore, it's all over......"

Lu Qingqing lay on the table and choked up.

In the past few weeks, she has been at home, and her father has beaten and scolded her.

Because he was afraid that he would provoke the Lu family and lose the big project with the Morningside Group, only his mother would comfort her, but after a few words of comfort, he began to quarrel with his father again......

I don't know what's going on with my legs, but now I can't bear the pain at every turn, and I can't find any problems when I go to the hospital......

She didn't want to stay at home for a minute, so she endured the embarrassment to come to school.

But the rest of the students .....

Only Ziyu still treats her so gently......

Lu Qingqing's eyes were sour, and he glanced at the math competition book pressed by Lu Ziyu in the corner of the table, his lips were also bitten hard, his fingers were pinched, and his emotions transitioned directly from embarrassment and hatred to hatred.

It's all to blame on that Lu Yu......

caused her to be spurned by these people, and Ziyu had to prepare for the math competition again......

She won't let her go......

The corners of Peng Xiaolan's eyes in front of them were upturned, looking at the thoughts that had a little success in them.

Lu Yu is really powerful, just a video, it makes the invincible road light like this, who should be next......

At this moment, Peng Xiaolan had completely forgotten Gu Yu's warning, and was just fantasizing about the next person to be knocked down by her.

Lu Ziyu was relieved to see that his eyes were red and he was caught in his own heart.

In fact, after Lu Qingqing's accident, she also thought about getting rid of this burden.

However, Lu Qingqing is really one of the few idiots in the class, who has a bad brain, likes to be self-righteous, and is easy not to induce, and she doesn't want to give up such a "good friend" who is willing to charge for her for the time being.

Since she didn't climb on herself, Lu Ziyu didn't mind, and gave a little gentleness and understanding, so that Lu Qingqing trusted her more.

After all, that Lu Yu is so evil every time, she has avoided those frames, and if she wants to take action herself, she has to plan well......

The eyes of the girl who was still soft-eyed just now flashed a dark color that was too fast to see clearly.
