I Use Illusions To Control The Whole World Chapter 20
Just a trigonometry problem
“Yang Dongqing, do you know what a student’s greatest responsibility is?” Su Mu interrupted calmly.
“What are you trying to pull this time?!”
“A student’s greatest responsibility is to study. And you, Yang Dongqing, as one of the worst-performing students in the class, have seriously dragged down the class average. As the class monitor, I have the duty to tutor you after school.” Su Mu pushed up his glasses, holding a thick stack of books, looking like a model student in both character and academics.
“Su Mu! You’re seriously insane! Why the hell would I study?!”
Su Mu shook his head with disappointment. “Such a poor attitude toward learning… looks like I need to give you a little motivation.”
As he spoke, he took out a math workbook and placed it in front of Yang Dongqing.
“Come on, solve this trigonometry problem. All the necessary formulas are in the book.”
“I’ll solve your—” Yang Dongqing was about to curse when Su Mu’s next sentence made his face change instantly.
Yang Dongqing immediately looked up, his face filled with fury. “You dare! If you lay a single finger on her—”
“Shh. No need to panic. I’m a man of my word. If I say I’ll cut off one finger, I won’t cut two. Right now, the chance to save her is right in front of you. If you really love her and don’t want her to get hurt, then solve this trigonometry problem.
It’s just a simple problem. You’ve studied this in class. The textbook is right in front of you. If you can’t do it… well, don’t blame me.
Now, your time starts.”
Su Mu smiled as he pulled a pocket watch from his coat. Its intricate golden patterns gleamed under the light. He set the watch on a nearby table and walked out.
Yang Dongqing cursed him repeatedly, but after a while, he had no choice but to turn his attention to the math problem. He knew this lunatic Su Mu was capable of anything.
“Alright, it’s just a trigonometry problem. Easy.” He took a deep breath and carefully read the question.
[Given in triangle △ABC, ∠A = 60°, a = 3, b = √3. Find the measure of ∠B.]
Time ticked by—one minute, two minutes, three minutes…
“Aaaah!! Damn it! What the hell is angle B?!”
There’s a saying: when a person is desperate, they can do anything. Clearly, that’s a lie. Because when it comes to math problems, if you don’t know it, you just don’t know it.
Fifteen minutes later, Su Mu gracefully walked into the dungeon, leaning on his cane, holding a crystal wine glass filled with deep red wine.
“Yang Dongqing, do you have the answer yet?”
Completely consumed by math, Yang Dongqing suddenly looked up. He looked terrible—bloodshot eyes like a spiderweb, muttering constantly: “sinB = b × sinA ÷ a… so √3 × sin60°…”
“Fifteen minutes are almost up.”
“Don’t interrupt me! I’m almost there. sinB = 1/2! Since a > b, then ∠A > ∠B, and because sinB = 1/2, so…”
His eyes suddenly lit up. The answer burst out of him: “∠B = 30°! Hahaha… I did it!!”
Clap clap clap…
Su Mu clapped with satisfaction. “Congratulations, Yang Dongqing. You’ve just saved one of Miss Jasmine’s fingers.”
But before Yang Dongqing could even enjoy the moment, Su Mu pulled out another math problem. “Another fifteen minutes. If you can’t solve it, I’ll cut off one of her toes.”
“Su Mu! You bastard! What do you want from me?!”
Su Mu gave a faint smile. He thought Yang Dongqing’s mental state was still too good. A few more problems should fix that.
“Fifteen minutes. Time starts now.”
With that, he walked off, leaning on his cane.
After venting his rage, the mentally exhausted Yang Dongqing had no choice but to look at the new math question.
One glance, and his vision went dark.
[1, 3, 8, 20, 48, 112, 256…
(1) Find the general formula for the sequence.
(2) Find the 20th term of the sequence.
(3) From which term onward is the value greater than ___?]
“Su Mu! You mother****er—!!”
…
…
The next day, Yang Dongqing didn’t sleep at all.
He spent the entire night doing math problems. His mathematical skills had improved greatly—he now fully grasped trigonometric formulas, arithmetic sequences, geometric sequences, systems of linear equations, and other advanced math concepts.
But his mental state was near collapse. His eyes were sunken, his face expressionless, and his gaze empty.
The group of flirtatious women returned again, but no matter how seductively they danced, Yang Dongqing’s eyes didn’t even twitch.
In the surveillance room, Su Mu watched closely. The timing was just about right—it was time to begin hypnosis.
Everything he had done before this had been to wear down Yang Dongqing’s mind. Especially the math problems. Only those who’ve struggled with math can truly understand the pain of wracking your brain and still finding no answer. Unfortunately for Yang Dongqing, he was that kind of student.
Transcendents have strong mental resistance. Only when that resistance is worn down to the extreme can hypnosis succeed.
This time, Su Mu was going for deep hypnosis—not just psychological suggestion.
Psychological suggestion is shallow. The subject retains their thoughts but responds based on suggestion.
But deep hypnosis, like what he used on members of the Viper Gang, completely distorts the subject’s thinking. However, this kind of deep hypnosis is not permanent—it needs to be reinforced periodically. Maybe once his Mental Power grows stronger, he can perform permanent hypnosis like a branded mental imprint.
Thud!
The dungeon door opened again.
The dazed Yang Dongqing shuddered as soon as he heard the door, like a conditioned reflex. Fear immediately appeared on his face.
“No… No more! I don’t want to do math anymore! Urgh…”
He actually began to dry heave.
Su Mu was very pleased. “Yang Dongqing, it seems you’ve thoroughly absorbed and digested all that math knowledge. You’re even overstuffed now.
It looks like we can move on to the final stage.”
Yang Dongqing didn’t even respond. He just kept muttering unconsciously: “sin, cos, tan, cot…”
