The night before the college entrance exam results were released, I redeemed my Peking University ad

In the live stream, viewers finally saw the question on the blackboard and went wild:

"Holy crap! Is this a high school level question?"

"I have a bachelor's degree, how come I still can't understand it?"

"Cheating! Giving the kids questions that are way beyond their level!"

Just as the barrage of insults was reaching a fever pitch, a verified account with the ID "Teacher Olympiad Math King" suddenly posted five consecutive barrage comments.

"Holy crap! Isn't this a variation of the final, most difficult problem from the National Mathematical Olympiad two years ago?"

"This question is indeed within the syllabus; it uses only high school level knowledge. But I can say with certainty that out of all high school students in the country, no more than five people could answer this question correctly!"

"Note that it's not no more than five percent, it's no more than five people!"

"No! I looked at it carefully, and this question is even harder than the original one from back then!"

"The original problem provided a crucial scaling hint, but this problem removed it! You have to find the scaling path yourself to proceed! This change directly increases the difficulty by an order of magnitude!"

The comment section exploded after "Teacher Olympiad Math King" posted five consecutive bullet comments.

"What? An Olympiad problem? Or a more difficult variant?"

"This is cheating!!! This is blatant cheating!!!"

"Cheating! Shameless! The Kochi Alliance should just be renamed the Shameless Alliance!"

"I initially thought these people had at least some academic integrity, but now it seems they have none at all! A bunch of sore losers!"

"Ji Bai! I'm not answering anymore! You've already won!! The whole nation is watching, and the truth about who won and who lost is clear to everyone!!"

……

"Wait! Everyone, stop yelling!! Ji Bai seems to have moved!!!"

"He's not really going to answer this, is he?? This is an Olympiad-level math problem!! There are probably no more than five people in the whole country who can solve it!!!"

"He wrote it!! He really wrote it!!!"

"Wow, really? He actually answered that???"

……

Ji Bai looked at the problem on the blackboard, and after about two or three minutes, he had a good idea of ​​what it was.

It's really difficult.

If a typical high school student were to attempt this, they would likely be unable to answer the question, and in fact, the vast majority of high school students wouldn't even be able to understand the question.

Even with his high school math expertise, solving this problem within half an hour would be no easy feat.

But don't forget, he's not just proficient in high school math, he's also proficient in university math!

If you look at this problem using university-level mathematics, it's not that difficult.

Asymptotic analysis of sequences, a variant of Euler's summation formula, and the construction of a clever auxiliary function...

By approaching the problem from a higher dimension to a lower dimension, the "final challenge" feeling of this question is instantly eliminated.

It's only difficult within the high school framework; within the university mathematics system, it's merely an above-average homework problem.

Ji Bai picked up the chalk and wrote the first line on the blackboard.

"First, note that we can construct an auxiliary function here and use the bounding method to process the inequality on the left side..."

"Clearly, this sequence is monotonically decreasing, and its limit converges to 0..."

"It's not hard to see that this can be solved in one step using the Lagrange Mean Value Theorem, without taking any detours..."

The chalk flew across the blackboard, and lines of formulas were written in a blur.

At this point, the Kochi Alliance was completely dumbfounded.

Director Huang was stunned!

The bespectacled man was dumbfounded!

The chemistry PhD was dumbfounded!

The physics professor was dumbfounded!

Wait... buddy, who are you? Are you the reincarnation of Ramanujan?

This is a fucking Olympiad final round question!

You finished it in three minutes?

It even includes advanced theorems that can instantly defeat opponents?

Ji Bai is still writing.

"It's obvious that by substituting, we can obtain this constant..."

In conclusion, the original inequality holds for all positive integers n. Q.E.D.

"Smack."

Ji Bai put down the chalk and dusted off his hands.

As the final stroke was made, the entire auditorium fell into a deathly silence.

Principal Wang slapped his thigh, almost jumping up: "Great!!!"

The math teacher at No. 99 Middle School was so excited that he was trembling all over and tears were streaming down his face. This was his student!

Li Mei stood at the front, covering her mouth with both hands, tears streaming down her face uncontrollably through her fingers.

The live stream chat went completely wild!

"The certificate is out!! The certificate is out!!!"

"This is an Olympiad-level math problem!!! No more than five people in the entire country could solve it!!!"

"My God, this isn't just doing problems, this is real math!! This is genuine mathematical thinking!!!"

"The way that auxiliary function was constructed... my advisor used a similar approach in a seminar! Ji Bai is only eighteen!!!"

"I cried! I'm a grown man, and I cried watching the live stream! 99th Middle School! A dilapidated sect! And yet, they produced an unparalleled genius!!"

"Ji Bai is awesome!!!"

"An epic moment has been created!!!"

……

At the same time, a system notification finally rang in Ji Bai's ears:

[Ding! Shock from Lin Mingyu, +1]

[Ding! Shock from Liu Bowen, +1]

[Ding! Shock from Pan Wei, +1]

[Ding! Shock from Wu Li, +1]

[+1, +1, +1, +1...]

Ji Bai glanced at the system panel; the shock value had already soared to over 1000 and was still jumping at a visible speed.

This was a great deal!

Meanwhile, the members of the Kochi Alliance were already making quiet moves.

Not anymore!

This person is terrifying!

You're supposed to be a math Olympiad gold medalist, and you're trying to play dumb with me?

You little silver coin!

slip away!

If we stay any longer, not only will our faces be crushed, but our bones will be crushed too!

Just as these highly educated intellectuals had quietly retreated to the sidelines, preparing to collectively slip away, a loud voice suddenly rang out.

"Distinguished experts and scholars, you've come from afar, please don't rush off!"

Principal Wang had somehow managed to block the entrance to the auditorium, his smile incredibly bright, his expression as sincere and enthusiastic as could be.

"I've prepared some light wine at the school cafeteria to welcome you all! Would you do me the honor of joining me?"

As soon as Principal Wang finished speaking, the head of the grade level rang out.

"Principal, I'm afraid it's not that the experts are unwilling to lend their presence, but rather that even if they wanted to, they couldn't."

Principal Wang feigned surprise: "Oh? Why?"

"Because their faces are right there!"

As the grade head spoke, he pointed to the spot where Ji Bai's feet were.

The meaning is obvious: these people have no shame left; Ji Bai has long since trampled their faces underfoot!

"Hahahahaha!"

The teachers of No. 99 Middle School burst into laughter that had been building up all night.

Ji Bai, you really made me proud!

The viewers in the live stream were laughing uncontrollably.

"The head of the grade is killing me by attacking my spirit!!!"

"I'll remember the phrase, 'Their faces are still there,' I'll use it when we argue!"

"They've lost all shame! They're trying to slip away unscathed!"

"Wait! Stop laughing! Where's the money? What happened to the promised 600,000???"

"And running laps! While running, they keep shouting that they're trash!"

"Where's the man with glasses? Wasn't he jumping around the most a moment ago? Why is he hiding at the back now?"

"The whole country is watching! If you renege on this bet, you can forget about working in academia!"

……

Seeing this situation, Director Huang knew that it was completely impossible to sneak away.

He mustered all his strength and forced a smile from his petrified face.

The smile was so ugly that even the students behind him couldn't bear to look at it.

"Ji Bai is truly a young hero! Principal Wang's leadership is excellent!"

"But it's too late today, so we won't have any food or drinks. We need to catch the high-speed train back to Shanghai."

"Don't worry, Ji Bai, someone will deliver the 600,000 to you, not a penny less!"

"Everyone, we'll take our leave now."

Director Huang used the last shred of dignity to say a few polite words, and then prepared to leave with his men.

He couldn't stand it for even a second longer.

This dilapidated No. 99 Middle School, this run-down school that doesn't even have a plastic track, every fluorescent light tube in this auditorium made him feel hot all over.

He just wanted to get back into that Coaster immediately, draw all the curtains, and never set foot in Fucheng again in his life.

Principal Wang was stunned. He's leaving already?

He wanted to stop him, but when he opened his mouth, he couldn't come up with a suitable reason.

The two sides are not from the same system, and the other side consists of prominent figures. A few sarcastic remarks were already the limit.

But just then, Ji Bai spoke.

"Gentlemen,"

"Come whenever you want, leave whenever you want..."

"Do they really think my No. 99 Middle School is a den of snakes and rats?"
