[Zhongyingmei] I'm the villain boss, okay?

Hilda also seemed to be unable to react, holding the pencil in a daze, without making a sound for a long time.

"Oh my god! Doesn't it take several days for someone to submit the answer to the special task assigned by the professor? One year, it was said that there was not even one person who submitted the correct answer... How did you do it?" Sophia said with a look on her face. Shock.

"I, I don't know..."

Sophia gently pulled the draft paper, pointed at the letters with the tip of the pen, and read carefully line by line. After 5 minutes, she felt... There was no problem.

Although she couldn't figure it out, she could vaguely understand the answer!

"Oh my God!" Sophia almost cried out, "Quick, I'll call the teacher! Felix will teach uuuuuuuuuuuuuuuuuu......"

The arm that Sophia was about to raise was pressed down by the girl beside her, and Hilda's other hand tightly covered Sophia's mouth, preventing her from making a sound.

"Mmmmmmmmmmmmm!"

Sophia gestured for a long time, indicating that she would not yell at the teacher, and then Hilda slowly put down her trembling hands, and continued to turn her head to stare at the draft paper in front of her.

"...What's the matter? Why didn't you let me call the teacher? Is there something wrong with the process?" Sophia asked in a low voice, leaning her furry head over.

"No...the process is probably fine." Hilda lowered her eyes.

"Then why?" Sophia was puzzled.

Hilda still hung her head down.Even if she only imagined the scene of "Sophia raised her hand, and everyone's eyes are on them", she couldn't control her heart palpitations, and her fingertips trembled.

"Then let's go to the teacher alone after class?" Sophia asked softly.

Hilda paused, then nodded slightly.

"Students, maybe some of you have heard that there will be an 'additional bonus' for each 'special mission' - although, since I coached, no one has ever received this extra bonus." Amidst the booing of the students, Professor Felix lifted his glasses with a smile, "This time the additional 'BONUS' is a bit more special—students who solve the problem before the end of this class can have the opportunity to interact with the mysterious 'BONUS'." Professor Moriarty's call to discuss mathematics problems—coincidentally, my mysterious friend's schedule has become relatively free for some reason recently, so I mentioned this matter to him. He is also looking forward to it, Is there any student who can perfectly solve this well-designed problem in just one and a half hours of classroom time."

"What? Was this question designed by 'Professor Moriarty'?"

"Wait, wait, who is 'Professor Moriarty', how do you all know it..."

"Professor Moriarty, you don't even know? The mysterious genius mathematician who proposed a perfect answer to the 'Riemann Hypothesis' a few years ago! No one has seen his true face, even the account where he submitted the answer It's all an untraceable anonymous account on the dark web. When he submitted his answer on the 'Riemann Hypothesis', he just sent a hasty email, didn't say a word of redundant nonsense, as if he just picked a random date , just throwing the process that I have already solved for everyone to take a look. Therefore, everyone calls him: Lone Ranger Mo Shen."

"To be honest, no one even knows whether ta is a man or a woman. It's just because the name sounds like a man, so he is called 'he'."

"Nobody knows him? But didn't our professor say he was a good friend of Professor Moriarty?"

"Don't ask me, how do I know why the professor knows Mo Shen..."

"Don't get too excited, how can it be possible to solve this problem in class... and it's impossible for anyone to do it well, I'm afraid the professor is just kidding us."

Sophia blinked her big eyes twice, looked at the draft paper, and then at Hilda, feeling... a little confused.

"This, this, the 'Moriarty' the professor mentioned, is that mathematician you particularly admire?"

Sophia didn't wait for Hilda's answer, but she saw a gleam of light that she had never seen before, shining brightly in Hilda's eyes.

However, after waiting for several minutes, she still didn't raise her hand to call the teacher.

Sophia pondered for a moment and made a decision.

"Professor, I made it!"

"..."

"Who?"

"What?! Did I hear correctly..."

For a moment, all eyes were on Sophia.

"...Oh?" Professor Felix lifted his glasses lightly, the transparent lenses reflected rustling light in the sunlight, "Student Sophia, you mean, you have already solved the problem Is that a problem?"

"Yes." Sophia secretly pushed Hilda's fingers away from her sleeve, and stood up.

"In that case...then please go to the blackboard and explain this topic to the students."

Sophia gave Hilda a "don't worry, I can do it" look, then sneaked a glance at the draft paper, went straight to the blackboard, and wrote down the complete answering process.

Sophia turned around slowly amidst the noise of surprise, and looked at Professor Felix with a smile.

"Teacher, do you read right?" A huge smile appeared on the little girl's pointed face.

"It's... amazing!" Professor Felix opened his eyes wide and looked at Sophia in surprise, "The whole process was fine, but I have a small problem that I would like to ask you to explain in detail. Explain—how does the ninth step in the proof process directly obtain the equivalent formula of the tenth step?"

"Well, ah..." Sophia hurriedly turned her head to look at the blackboard, quickly found the position of the ninth and tenth steps, and took a closer look... Sure enough, there were two lines that she didn't quite understand. .

This is always the case when answering math problems. A rough look at the process seems to be very problem-free, and I understand everything, but a closer look shows that I don’t know how each step came about.

Sophia: Pills.

"Let me think about it..." Sophia tried hard to restrain the eyes that tried to look at Hilda for help, scratched her head, and began to analyze, "First step nine... there is a variable m, this m, what does it represent? Ah! Look here, it is 2n+1. So, my friends, this n, what does it represent? n..."

Sophia quickly glanced at the formula, but didn't realize that the professor had already quietly walked to her seat, and picked up the draft paper while Hilda was panting suddenly.

"Ah!" Sophia finally found it, "This n is k*1/N^2... Teacher, what are you doing!!!"

Sophia watched in horror as Professor Felix was standing by her seat in a daze, reading the draft paper full of proofs with relish, and turning the paper over again, she saw dense pencil calculation drafts.

Sophia couldn't be more clear. The assignments she submitted are always in a mess, and the drafts are written directly next to the proof. The professor always says it is too imprecise and asks her to correct it.But Hilda's homework is just the opposite - neat, clear, and rigorous, just like the scratch paper in the professor's hand.

"Sophia, is it true that you solved the problem? The draft on the draft paper in this chapter complements the proof on the blackboard very well, but it doesn't seem to be your handwriting." The professor said gently, "It seems a bit Like... Hilda's handwriting."

Sophia:! ! !It's over.

"No, teacher, you read it wrong..." Sophia trotted over, picked up the draft paper, and said in a panic, "I wrote this! How could it be written by Hilda? No matter how careful you are have a look......"

"Hilda." Professor Felix did not answer, but turned to look at Hilda, who was hanging her head aside. "Did you complete such an exquisite answer?"

The line of sight several times earlier focused on Hilda in an instant, making every inch of her nerves tense.

The classroom with a high ceiling is clearly very spacious and spacious, and the sunlight pours into the room through the windows, making it very warm.But Hilda felt that something invisible squeezed her body like a tide, pinched her neck, and made her almost unable to breathe.

The scene from ten years ago flashed before her eyes like a slideshow. Hilda tried hard to control her brain and told herself: This is the school, this is the classroom, and the people looking at her are all friendly classmates. No malice, no malice, they won't look at you, won't follow you, no one will follow you anymore...

Just as she slowly regained her sanity, suddenly, a pair of unfamiliar hands rested on her shoulders.

"Hilda, eh? Didn't you catch that?"

Hilda looked forward in a daze through trembling eyelashes.In a halo of light, a man was staring straight at her, just like that year.

"Go, go away!!!"

"Snapped!!!"

With Hilda's nearly inflected scream.The glass around the classroom shattered instantly, and sharp debris shot into the room quickly.The towering classroom seemed to have been punctured by something, glass shards mixed with an inexplicable aroma of plants and trees poured into the room from all directions.

"Students! Classmates..." Professor Felix seemed to be shouting anxiously, but no one cared about him at the moment.

While the classmates were dodging in panic, Sophia slowly looked out the window as if feeling something, and saw a scene that shocked her physically and mentally.
