It's still the same in the Academic Affairs Office.

Two or three computers, a few desks, and a row of old-fashioned cabinets against the walls, piled high with papers.

After Director Niu walked in with Su Mu, he immediately attracted everyone's attention.

Su Mu nodded awkwardly, these teachers are quite familiar, after all, he has been here once last time because he was suspected of cheating.

"It's okay, you don't have to stress anything."

"Not a bad thing."

Director Niu patted Su Mu on the shoulder and walked straight to the innermost desk.

The documents on the table were much neater than the last time Su Mu came, and next to the documents was a black double-layer thermos cup, which looked like it was soaked in wolfberries.

There is also a pot of succulents in the corner of the table, which is very fresh, and it should have been bought from the vendor at the school gate not long ago.

To Su Mu's flattery, Director Niu didn't tell Su Mu about business for the first time, but took out a paper cup and poured Su Mu a glass of water.

"Come on, come on."

"Tea first."

Su Mu nodded awkwardly, took the disposable water cup and took a sip gently.

In the past, when I was a scumbag, I basically did something wrong before I got in touch with the teacher, and most of the teachers also reprimanded and hated iron and steel.

I didn't expect to be a top student now, and there is this level of treatment.

Finally.

Director Niu spoke.

A smile and relief on his face.

"Did you fight in Happy Valley before?"

"Ah???h Su Mu's face was stunned, and he didn't expect Director Niu to mention this stubble at all. “

"Today, the school leader said that Happy Valley has sent someone to send a pennant."

"It's a good thing that you have this kind of thing!! Why refuse at that time! ”

The more Director Niu looked at Su Mu, the more happy he felt, and today because of this matter, the school leaders came to him and praised him.

"Uh... That's the thing..."

Looking at Director Niu's concerned eyes, Su Mu could only nod.

Director Niu took out a red certificate from the drawer and said, "There are not many young people like you who are brave and brave now, and you have to bear this kind of honor!" Our school also has a light on its face. ”

"I came to you today, mainly for three things."

"First of all, this certificate was given to you by the school!" Director Niu handed the certificate to Su Mu.

"Secondly, according to the practice of our school, there is a student representative at every opening ceremony."

"After today's discussion, the leaders decided to elect you as the student representative this time!"

"You go back this weekend to prepare a draft, and the opening ceremony should be after next Wednesday's recess exercise."

"The student representatives of the opening ceremony??"

Su Mu's expression was stunned again.

"What kind of reading the manuscript in front of the whole school?"

Director Niu nodded.

"It's okay if you have the manuscript ready to read, but it's best to memorize it, about five or six minutes."

"When the manuscript is ready, bring it to me and show it, and I'll help you check it."

"Okay..."

Su Mu nodded.

He had never spoken on such an occasion since he had been a student.

The experience is also good.

What if you might have completed one of the system's hidden achievements!!

"There is a third thing, a reporter from our Qianbei Times will come to interview you next week."

Su Mu: "???? ”

Su Mu was already a little surprised for the first two reasons, what the hell is this reporter??

However, before he could react, Director Niu continued.

"The pennant will also be given to you at that time, and you may also take a group photo with our principal."

"These things are counted in your file, which is very helpful for your future future!"

"Come on!" Director Niu patted Su Mu's shoulder again, like a kind of elder care for the junior, wanting to get closer to him.

Su Mu smiled bitterly.

This change of identity, he really can't adapt to it.

......

It's a pity.

When Su Mu returned to the classroom, the class teacher's prizes had already been distributed.

Originally, he was still waiting to see the surprised eyes of the whole class, and then put on a good show in front of Yan Xiaoke.

Unexpectedly, due to the arrival of Director Niu, Su Mu missed this link perfectly.

After class, the students left the classroom one after another.

and Qi Yunfan went to the Internet café to get on the network, and under Su Mu's deliberate operation, they basically lost one game and won one game to get revenge points.

Qi Yunfan kept sighing that he was unlucky today, and his ranking score barely rose.

After returning home in the evening, Su Mu began to seriously prepare what Director Niu called the "speech".

This kind of manuscript to be prepared for reading in front of the whole school, he thinks it is better to be well prepared.

Saturday.

The weather is still sunny and gradually starting to warm up.

However, Su Mu rarely didn't play a game this morning.

Since the skill of e-sports has been improved, the game seems to have become less attractive to Su Mu.

Although Su Mu obtained the skill of e-sports from League of Legends, he can still play a role when playing Glory of Kings.

The game is such a thing, in terms of operation, awareness and luck, with Su Mu's current level, the low-end game is basically a winning streak, and the high-end game is too wasteful.

From time to time, I also matched a few Shenkeng teammates.

Either the opponent is too vegetable, or the teammate is too vegetable.

If it weren't for Yan Xiaoke always letting herself take her to the top points, Su Mu wouldn't even want to fight for the glory of the king.

Su Mu suddenly remembered his previous life.

At that time, although I was a scumbag.

But at least live a full life, sand sculpture, and joy.

And now as a scholar, it's too unpretentious and boring.

"Huh?"

Su Mu was lying on the bed holding his mobile phone and swiping the news idly.

Suddenly caught a glimpse of a book in a box under the desk.

Selected Mathematics Olympiad for Junior High School

Maybe it's because of fate, or maybe it's because it's too boring, Su Mugui got up and took it out.

Su Mu's grades in junior high school were actually quite good.

It was only after graduating from junior high school that it slowly declined.

At that time, he also went to participate in the Olympiad with Yan Xiaoke.

Well.

It's all about engagement.

There was already some dust on the book, and Su Mu wiped it with his hand.

There's too much ash.

I accidentally got it on my hand.

Su Mu had to go to the bathroom and wash his hands again.

Wait until everything is taken care of.

The atmosphere suddenly became a little reverent.

If Su Mu remembers correctly, this is the first time he has taken the initiative to study at home since he was in high school.

Su Mu casually flipped the page.

Find the integer solution of the equation |xy|-|2x|+|y|=4.

His eyes lit up.

Su Mu took out a pen and paper, thought about it for a while, and directly extracted the common factor to become |x||y|+|y|-2|x|-2=2, which is then (|y|-2)(|x|+1)=2|x|+1.

The corners of his mouth are slightly raised.

The answer is almost out.

(|y|-2) (|x|+1)=2|x|+1 is a positive integer, |y|-2 is also a positive integer, and then 2 is factored into a prime factor 2=2*1

|x|+1=2

|y|-2=1

or

|x|+1=1

|y|-2=2

Get x=±1 ,y=±3 or x=0 ,y=±4...

Su Mu touched his chin.

It's a simple question, but it's kind of interesting.

A terrible thought popped into his head.

Inexplicably.

It seems that doing Olympiad problems is more fun than playing games.
