"IMO Title?"

Su Mufeng looked dazed, and he couldn't understand Old Man Liu's words for a while.

He was still immersed in the mysterious realm just now, and his brain seemed to be swirling with complicated numbers and formulas.

Old man Liu smiled and said, "IMO, International Mathematical Olympiad."

As soon as Old Man Liu said this, before Su Mufeng could react, the students under the podium broke out into an uproar.

Countless unbelievable eyes focused on Su Mufeng again, and even many people had a look of reverence in their eyes.

"International Mathematical Olympiad! No way! What a concept! ”

"I didn't wake up today, did I? In this shabby place of our school, can there still be people who do IMO questions? ”

"If you don't make a hit, it's a blockbuster. Su Mufeng is too low-key, right? ”

"The day before yesterday, I took a mock exam of 148 and was still complacent in front of him...... Now, want to die. ”

"Is it too late to apprentice?"

It's no wonder that these top students in the first high science class are so excited.

IMO, perhaps most people have not even heard of this abbreviation, but it is a thunderous name in the academic world of education.

Does it represent the highest level of mathematics for high school students around the world?

Do you think the word "high school student" sounds very low?

In most fields, there is indeed a direct correlation between age and academic level, and an old professor who has been engaged in academia for most of his life is of course completely incomparable with a high school student, and the competition of high school students is naturally just a child's game.

But math is different.

The International Mathematical Olympiad is even different.

Old man Liu once told two stories to the students in the real yàn class.

The first story took place in an International Mathematical Olympiad in the 80s, where there was a number theory that was difficult to solve and ingenious, and several mathematicians present discussed it for a day and a night but did not come up with it.

But there were 10 people in the exam room who made it.

The second story is that in 2009, the last question of the International Mathematical Olympiad, it took Tao Zhexuan 7 hours to finally make it.

——Tao Zhexuan, who teaches in the Department of Mathematics at the University of California, Los Angeles (UCLA), is the only Australian-Chinese mathematics professor to win the Fields Medal, the highest honor in mathematics, and the second Chinese to receive this honor after Yau Chengtong. He is an important mathematician in the fields of harmonic analysis, partial differential equations, combinatorics, analytic number theory and other important mathematical research fields, and is known as the "Mozart of mathematics".

According to the words of the cousin of the representative of the mathematics class in the class, the mathematics level of the master's degree of the mathematics department of 211 colleges can only be eaten behind the undergraduate students of the Department of Finance of Tsinghua University, and the mathematics level of the undergraduate students of the Department of Finance of Tsinghua University is ...... Not even qualified to eat ashes behind the backs of IMO national team members!

Therefore, after hearing Old Man Liu admit that this question is a question of the International Mathematical Olympiad, all the students will burst out with such excitement.

First of all, I am extremely surprised by the incident itself.

Secondly, he expressed extreme indignation at Old Man Liu's cheating behavior.

In the end, of course, it is to express an abnormal worship of Su Mufeng!

At this time, Su Mufeng finally came back to his senses completely from the realm of selflessness, his eyes widened in disbelief, and he opened his mouth and said, "This, isn't this a high school level?"

- Su Mufeng, who was immersed in calculations, actually didn't realize from the beginning that the difficulty of this thing was far beyond the "high school level".

Hearing this, the smiling expression on Old Man Liu's face suddenly froze, and he turned his head away in embarrassment.

The phrase "high school level" just now was said by himself, and now it is repeated by Su Mufeng...... It's a slap in the face.

The corners of the students' mouths twitched.

"A taunt from the god of learning?"

"Old man Liu was dealt 190,090 points of critical damage!"

"Hey, this is a map cannon, you forgot about the damage we suffered!"

Su Mufeng didn't need to look at it to know that these people must be the perennial Internet café LOL in the class, and they can also sit in the top ten in the school again and again.

Listening to the louder and louder voices from the audience, Old Man Liu's face was really a little unbearable, fortunately, the class bell came to the rescue at this time.

As soon as the bell rang, Old Man Liu slapped the desk and said with a full of anger: "Class!"

After saying this, no longer caring about the group of students in the audience who had begun to discuss fiercely, Old Man Liu patted Su Mufeng's shoulder and said, "Let's go, follow me to the office."

Su Mufeng couldn't cry or laugh, but he could only follow Old Man Liu out of the classroom door.

This time, it seems like it's going to be big?

Su Mufeng thought back to the fantastic "realm of selflessness" just now, and sighed, like a middle-aged man in his thirties.

Fortunately, he didn't know about the commotion he had just caused on the football field, otherwise, the age of this sigh would probably increase the strength of Banjiazi and evolve into a sixty-year-old man.

Walking in the corridor, Su Mufeng saw that many students from the next class ran to the door of the real class curiously, as if they had noticed the commotion at the end of the previous class.

Come to think of it, the time is not far off when this incident spreads all over the campus.

Old man Liu walked in front and said coldly: "Do you want to consider representing Nandu No. 1 High School to participate in this year's IMO domestic selection competition?"

"Hmm...... What the!? No way! ”

Su Mufeng, who was still distracted, didn't react for a while, subconsciously agreed, and then blinked, and after understanding Old Man Liu's words clearly, he hurriedly waved his hand.

Old man Liu turned his head and said with a smile: "It's a good thing that young people don't want to be too high-profile, but sometimes it's not good to hide too deeply!"

Su Mufeng's face stiffened, and he thought that a genius like Han Fei would come to learn mathematics for two years and then go to the competition, and it would be no problem to win a gold medal. He can only make an imposter with a mysterious outburst for a while, and he may not even be able to hold back a small question!

He knew that at last year's International Mathematical Olympiad, more than 40 teams from nearly 100 countries scored zero points!

What's more, Su Mufeng's main energy now can't be put on what kind of ghost competition, training Han Fei ...... Good education is the most important thing.

But obviously Old Man Liu didn't care about Su Mufeng's resistance, and patted him on the shoulder with a smile again, and said: "That question is quite difficult even in IMO, with your level of perfect solution in half an hour, it will definitely not be a problem to be selected for this year's national team."

"When the time comes, even if you get the most average competition results, you can be sent to Qingbei, are you really not tempted?"

Walks...... Qingbei?

After truly realizing the meaning of IMO representation, Su Mufeng couldn't help but hesitate.

Qingbei, the meaning of this simple proper noun, is really difficult to understand if you are not a student in this republic.

It was not so much the two highest institutions of learning as a faith, a pious yearning rooted in the hearts of countless families and children.

Su Mufeng was tempted.

Maybe the current Su Mufeng has crossed the level of mortals and stood in another different world, but his heart and mind are still stuck in the ordinary high school student three days ago.

Besides, the "realm of selflessness" just now is obviously related to talent, how can he deny the possibility of it appearing again?

And if that's not enough, there's ...... Sister.

Thinking of the girl who gave up her opportunity to receive a high school education and gave her future and hope to him, Su Mufeng hesitated.

He owes his sister too much, so even if there is even the slightest chance to make up for his sister's efforts, he doesn't want to give up.

Su Mufeng will never forget jì, he studied hard all night, and finally after entering the real yàn class with the highest heavy capital rate in the third year of high school, his sister's face was relaxed from the heart.

"You have to keep going, when you grow up, my sister won't be able to protect you anymore, so you must stick to it."

……

Su Mufeng stopped and stood in the corridor, looking at the bustling people under the tall buildings.

There seemed to be a decision in his face.

Old man Liu looked at Su Mufeng's expression, smiled unexpectedly, didn't say anything, and just continued to walk forward.

After taking two steps, as if he had found something, he patted his head.

"Alas, people have this memory when they are old, and the lesson plan is forgotten in the classroom, I'll get it, you go to the office and wait first."

After saying this, Old Man Liu hurriedly walked to the classroom.

Su Mufeng was stunned for a moment, turned his head, and nodded.

Before he could turn around and walk in the direction of the office again, a familiar figure suddenly caught glimpse out of the corner of his eye.

She had waist-length black hair and old-fashioned black-rimmed glasses that could hardly hide the delicacy of her appearance, and she was standing by the guardrail in the hallway, quietly looking downstairs.

The students next to them passed by, all of them looked at the figure in amazement and whispered.

"It's so beautiful, it's like a big doll."

"You look so young...... Is it a student at the attached high school? ”

"Fifteen or sixteen years old, maybe you're looking for your brother or sister?"

The girl in glasses didn't seem to hear these words, and still stood silently.

The breeze blew through her long black hair.

"Under the snow?"

In the distance, Su Mufeng shouted in surprise.

ps: The plot needs to modify a few sentences in the dialogue between Xia Ji and Ye Fei above, to the effect that the kidnapping action against Su Mufeng has been changed from "tonight" to "tomorrow night".

The aim is to adjust the order of the subplots and balance the scenes of the real-world and Middle-earth dungeons.
