Xueba, I beg you to go and escort him quickly!

According to (1) and (3), it is only necessary to take

mk=m0uk+7n0vk

nk=m0vk+n0uk

There must be:

m2k-7n2k=（m20-7n20）（u2k-7v2k）=-3

……

Done!

Xu Heng put down his pen and stretched.

The entire conference room was completely silent at the moment.

Everyone stared at Xu Heng.

One by one was stunned.

Xu Heng looked left and right, and then locked his eyes on the director general, Sun Jianhua and Hong Jingjun.

I don't know when, they have already stood together.

At this time, the director slowly came back to his senses, and then applauded Xu Heng.

"Crash..."

With the applause, everyone came back to their senses!

But in the next second, everyone did not applaud.

Those who were sitting, at this moment, all got up, those who were standing, and the teachers who had just stood up, all took half a step back, looked at Xu Heng sincerely, and then slowly bent down.

"I'm sorry! Student Xu Heng!"

Everyone is so sincere!

More than 100 people present!

All the excellent teachers from the eight cities in the whole province, at this moment, bow to Xu Heng and apologize!

In addition to Sun Jianhua and Hong Jingjun, even the director of the provincial education bureau was apologetic.

He also intends to bow to Xu Heng...

Xu Heng, "Stop! Everyone! What are you doing?"

"I know, your previous bad words were all intentional! It was all for acting! I didn't take it seriously for a while!"

"Don't blame yourself, get up!"

"Quick!"

"Old Sun! Old Hong! Come and help me!"

Among the many teachers on the spot!

30s!

40s!

There are even those in their 50s!

These people bowed to Xu Heng!

This is not to shorten the life of it!

Xu Heng's face was full of black lines, "Everyone! Get up quickly! Hurry up! Don't do this! Don't be like this!"

After all, they got up slowly, with apologetic expressions on their faces.

At the same time, they were also puzzled, "Student Xu Heng, how did you find out?"

"???"

Xu Heng rolled his eyes at everyone, "Teachers, although your acting is very good, you are too brainless!"

"You are teachers! No matter how angry you are, I don't think you will say it so blatantly on this occasion, right?"

The teachers were ashamed, "Ah..."

They looked at me, and I looked at you, and they all became embarrassed.

Things come to an end!

Everyone returned to the meeting of the examination paper group.

The director immediately announced, "Teachers, if we do this, aren't we preparing a difficult problem for each subject?"

What do these words mean?

It is to directly use Xu Heng's questions in the next nine school joint exams!

Xu Heng refused, "Wait! Teachers! And the director! Are you sure I won't tell my classmates about this exercise after I go back!"

"!!!"

The director and all the teachers laughed.

"Student Xu Heng, don't worry about it! We will modify and modify your topic based on it!"

"In addition, there are still more than three weeks before the exam, and we will come back here five days in advance to prepare the papers."

"It's time to run in..."

"..."

When the teachers heard what the director said, they also breathed a sigh of relief.

"It's okay, okay! Otherwise, with the difficulty of student Xu Heng's question, I think many students will be wiped out!"

"That's right! The joint entrance exam for the third year of high school is bound to be..."

"That's right! This third year of high school..."

"Senior year..."

Geek!

It was only then that Xu Heng realized that this entrance exam was for the third year of senior high school!

Because Xu Heng has always been a sophomore in high school, his identity is also a sophomore, so his subconscious is related to the sophomore.

But after the discussion of these teachers, he suddenly understood.

This Nine-School Joint Examination is only aimed at students in the third year of high school!

This is equivalent to a mock exam for the college entrance examination!

Xu Heng slapped his forehead, "Oh...｀ ~..."

"This is for me to give papers to the seniors and sisters in the third year of high school."

Xu Heng frowned, always feeling something weird.

But that's the end of the matter, that's all there is to it.

The examination paper group meeting was held for a whole day.

At noon, a group of people gathered for dinner, and they all surrounded Xu Heng.

Especially those teachers in the mathematics group, some even took the initiative to find Xu Heng and ask him for the question he asked before, without missing any few minutes of rest time.

Xu Heng knows everything!

He looked at these teachers, this is the professionalism and morality they should have!

Compared with the morning, this is really a different person.

Whether it is from the mathematics group or other groups, everyone admires Xu Heng very much.

The leader of the mathematics team laughed, "We didn't participate originally, because we know your strength, and the time you spent during the winter vacation is obvious to all of us!"

"But we can't stand the pressure of other groups! We can only cooperate with the performance!"

Xu Heng, "I'm actually curious, how did you know about this test paper?"

The leader of the mathematics team smiled, "Our teacher! Teacher Luo! Come here!"

A female teacher came to Xu Heng.

She looked at Xu Heng and said with a smile, "No wonder my daughter admires you so much. It turns out that you not only have outstanding grades, but you are also so handsome!"

Xu Heng, "Teacher, is your daughter...?"

"Luo Jianing, I'm her mother, Luo Yingnan."

"She is in your fan group, so she shared this test paper with me immediately, and I immediately shared it with the team leader."

Xu Heng understood.

"So that's what happened."

Xu Heng sighed, "I was always wondering how this test paper was known by the provincial government, now I understand."

Several people smiled.

And Luo Yingnan took out a notebook and a pen.

"My daughter is your fan! Xu Heng, can I do you a favor?"

Xu Heng, "Sign it?"

Luo Yingnan immediately shook his head, "No, no, no! Just a few words of encouragement will be enough!"

The corner of Xu Heng's mouth was drawn, "Are there any requirements for the font?"

Luo Yingnan froze for a moment, "???"

Sun Jianhua and Hong Jingjun stepped forward at this time.

Sun Jianhua said, "Xu Heng knows a lot of calligraphy. His calligraphy is worth a fortune. This is not bragging. At the National Revision Conference, many people rushed to buy his calligraphy!"

The real deal?

!!!

Luo Yingnan hesitated, a word of money...

She didn't want Xu Heng to encourage Luo Jianing anymore. After all, this character, no, it's calligraphy, and its nature is completely different...

Xu Heng glanced at Sun Jianhua, "Old Sun! You are exaggerating!"

As he spoke, Xu Heng took the pen and paper from Luo Yingnan, turned to the first page, and wrote:

"Since I was young in the thorny grass, now I gradually feel the basil. At that time, people didn't know Lingyun wood, and they waited for Lingyun to reach the top."

Use regular script!

One stroke at a time makes people extraordinarily solemn.

Sun Jianhua saw the source of this poem at a glance, and said with a smile, "Xiao Song, written by Du Xunhe in the Tang Dynasty, is good, very good!"

Luo Yingnan was also a little surprised. She thought it would be some kind of encouragement like "going to the next level", but she never expected it to be such a poem.

Xu Heng returned it to Luo Yingnan.

Luo Yingnan, "Thank you! Thank you very much! Thank you so much! Student Xu Heng!"

Xu Heng, "Easy to do."

Not long after, the afternoon meeting will begin.

In the end, the topic did not revolve around Xu Heng again, but started talking about the plans for the various subjects of the entrance exam.

In the last hour, the teachers in the mathematics group had a heated discussion on the finale question of mathematics.

Even the Red King Army was involved.

Xu Heng kept smiling.

Everyone looked at Xu Heng, wondering, "???"

"Student Xu Heng, what do you mean?"

Xu Heng, "Teachers, don't you think that instead of worrying about the difficulty of the finale question here, it is better to teach the candidates how to do such a question?"
