This Character is Suspected of Cheating! [Unlimited Flow]

The person He Yu had singled out and captured from the crowd—

was the class monitor.

The same class monitor who respected teachers and followed rules. The one who constantly maintained classroom order. The one who always took the lead whenever He Yu arranged something. The one who had repeatedly scolded Wanrenzhan and the others.

He was also someone Wanrenzhan had randomly pointed at before.

But at the time, nobody believed it.

How could such an upright student, such an excellent class monitor who respected teachers and disciplined classmates, possibly be the murderer behind Anna and You Mo?

Not to mention—

the mastermind who had hidden for three whole months.

No matter how anyone looked at him, he didn’t resemble a killer.

“Teacher He Yu?” The class monitor recognized He Yu from the voice. His face was full of confusion. “T-Teacher He Yu, h-how are you... dressed like Anna? What’s going on?”

“You killed You Mo!” The Cafeteria Uncle strode forward from behind He Yu, pointing the tip of his blade directly at the class monitor.

“What? What are you people even talking about?” The class monitor looked utterly bewildered, staring at them in confusion as though he genuinely had no idea what was happening.

The Cafeteria Uncle’s blade slashed downward viciously, aggressive enough to split him in half.

“AHHH—” the class monitor screamed. “Don’t! Teacher He Yu, save me!”

The blade stopped right in front of his face.

The Cafeteria Uncle asked viciously, “I’ll ask you one more time. Did you kill You Mo or not?!”

“I didn’t! I don’t know what you’re talking about! I didn’t kill You Mo, and I didn’t kill Anna either! I had no grudge against them!” The class monitor stared stiffly at the blade, anxiously defending himself. “What exactly are you trying to do? Why are you trying to kill me?!”

The Janitor looked toward He Yu. “How did you figure out he was the killer?”

Even now, she still couldn’t see a single flaw.

Every reaction and expression from the class monitor perfectly matched the identity of an ordinary student.

From the earlier confusion to the anxiety of being misunderstood—

there was nothing abnormal at all.

So how had He Yu identified him from within the crowd at a single glance?

The bullet comments exploded—

“I want to know too! There were so many students just now, and the class monitor was squeezed in the middle. I barely even noticed him.”

“Seriously, how did He Yu figure it out?”

“I don’t understand. Is he so powerful that he can identify the real murderer with one glance? That doesn’t make logical sense.”

“The class monitor’s reactions are completely normal. That’s not how a killer should react.”

“Could He Yu be framing him too? Just to advance?”

“Framing the class monitor for advancement is fine anyway. He’s just an NPC. Advancing is what matters most.”

......

Everyone present, from the audience to the people on the rooftop, was filled with curiosity.

He Yu lifted a hand to push up his glasses, only to suddenly realize he wasn’t wearing any today. Naturally, he lowered his hand again and calmly said:

“You really did disguise yourself well. You’ve probably lived your whole life wearing a mask, haven’t you?”

The class monitor’s eyes remained confused.

He Yu continued, “Within the crowd, it was difficult to judge from your expression. Because your reaction was identical to everyone around you. Mixed in among them, you were completely inconspicuous.”

Everyone: “......”

Then how the hell did you find him?!

“Teacher He Yu, what exactly are you talking about?” The class monitor already looked close to collapsing.

That reaction caused the people around them to start wavering again regarding the conclusion that he was the murderer.

Even the Cafeteria Uncle temporarily lowered his weapon, though his eyes still remained fixed on him, ready to attack at any moment.

He Yu said calmly, “You’re truly too good at disguising yourself. Even if I personally stepped in, I might not necessarily have been able to pull you out when all your reactions were identical.”

Before everyone could continue spiraling in confusion, He Yu tilted his head.

“But who said I identified you by your reactions?”

Class monitor: “......”

Everyone: “......”

Bullet comments: “......”

If not through reactions, then how exactly did he identify him?!

Everyone stared blankly at He Yu in shock.

He Yu smiled slightly. “Actually, from the very beginning, I never planned to judge by reactions. Your ability to disguise yourself is too strong. Just observing your response after seeing Anna wouldn’t have been enough to identify you.”

The mechanical eyes in Eugene’s head spun around as he hurriedly asked, “Then what the hell was going on?”

Wasn’t the entire point of pretending to be Anna to observe the killer’s reaction?

He Yu smiled faintly. “I used the elimination method.”

“The first seven killers who murdered Anna and You Mo were all in Class One. The scapegoat you selected was also from Class One. Considering how meticulous your thinking is, you yourself definitely had to be in the same class.”

He Yu paused before continuing:

“Once I confirmed that the real eighth killer was still hiding, I started filtering through Class One. I eliminated almost over half the students.”

If he couldn’t identify the murderer through flaws—

then he would simply remove everyone who definitely could not be the murderer.

That left less than half remaining.

He Yu continued, “Then, after cross-referencing with the transfer list, only six suspects remained.”

They had already analyzed earlier that the killer would definitely transfer this time.

This was the best opportunity.

The opportunity he had been waiting for.

Once the suspicious students were matched against the transfer list, only six suspects remained.

“Later, Eugene gave me the students’ family background list.”

At this point, He Yu casually patted Eugene’s head. Eugene was listening so intently he didn’t even resist.

He Yu continued:

“After cross-referencing that list, only three suspects remained. The class monitor, the discipline committee member, and the student sitting in the corner of the second-to-last row.”

On the ground, the class monitor’s eyes still looked confused.

He opened his mouth, seemingly wanting to defend himself.

He Yu bent down and raised one finger, signaling him not to speak.

“I didn’t disguise myself as Anna in order to observe your reactions. What I wanted to observe was the timing of your appearances.”

The corners of He Yu’s mouth lifted into a confident smile.

“The killer would not appear last night, so I eliminated the student sitting in the second-to-last row. The killer would definitely appear today, therefore... I eliminated the discipline committee member.”

The student from the second-to-last row had already been incited by Wanrenzhan and the others last night and had come along.

The discipline committee member never showed up today.

After school ended this afternoon, the transfer students would never come again.

Therefore—

the killer absolutely had to appear at noon today.

—Which left only the class monitor.

So He Yu had never identified the murderer with a single glance.

Rather—

whoever showed up was the murderer.

“Teacher He Yu, what are you even talking about? I’m not the killer, I really...” The class monitor looked frantic.

He Yu smiled and shook his head. “Stop lying to me. You are the eighth murderer. You were confident that hidden among so many students, you’d appear completely unremarkable. That’s why you dared to come investigate one last time before leaving.”

What he didn’t know—

was that He Yu’s method of deduction had long stopped relying on reactions and suspicious behavior.

He Yu bent down, staring directly into the class monitor’s eyes.

“This is your confidence. And you had every reason to be confident. But I’m also very confident.

“When I wasn’t certain who the killer was, observing your reactions could only create suspicion. But now that I’ve confirmed you’re the killer, every single one of your reactions looks full of flaws to me.”

The class monitor froze.

He Yu smiled, straightening up before suddenly asking:

“Do you know why I never eliminated this excellent class monitor from the start? Do you know why he remained on the suspect list?”

Everyone froze before shaking their heads.

He Yu said calmly:

“Because he talked about rules and discipline too much. He was deliberately branding himself. Someone with such an outstanding family background and such excellent personal qualities, yet constantly hanging rules and discipline on his lips, was eager to leave behind the impression of being a ‘good person who follows rules’—especially in front of me, the new teacher.”

He lowered his gaze toward the class monitor.

“Class monitor, your ability to disguise yourself was still lacking by just a tiny bit. A truly skilled master of concealment doesn’t deliberately paint themselves as a good person. Instead...”

“...they bury themselves among the crowd. They act until they disappear entirely. Completely inconspicuous.”

Absolute certainty filled He Yu’s eyes.

And through that gaze, he conveyed that certainty directly to the class monitor.

—Also telling him that all his disguises were now meaningless.

The real killer had been confirmed.

Seeing this, the anxiety and confusion on the class monitor’s face slowly faded away, returning to complete calmness.

He looked back at He Yu and tightly pressed his lips together.

Clearly, having the disguise ability he took pride in shattered so thoroughly had dealt him a severe blow.

“I was only one step away,” he said hoarsely.

He Yu nodded. “Yes. You were only one step away. Unfortunately for you...”

“...you met me.”

The class monitor’s expression darkened.

—The eighth true murderer had been confirmed.

—And He Yu had dragged him out through elimination alone.

Eugene suddenly understood and blurted out in shock:

“So, He Yu, you already suspected the class monitor before this, you just never told us? Pretending to be Anna was only for the final elimination process? And from the beginning, you already knew pretending to be Anna wouldn’t provoke any useful reactions?”

He Yu nodded righteously. “Yes.”

Eugene, Zhen Xing, Wanrenzhan: “......”

The livestream audience: “......”

Beside them, the Janitor suddenly offered a sincere suggestion:

“Teacher He Yu, in the future, if you already have suspicions and clues, maybe you should still tell everyone earlier? The way you do things is... kind of infuriating.”

Always speaking halfway.

Always acting mysterious.

Always waiting until the very end to suddenly throw out a shocking explanation.

He would casually toss out a sentence that stunned everyone speechless, only afterward explaining the correct conclusion he’d already deduced long ago.

This wasn’t just “kind of infuriating.”

This was fucking infuriating.

—Especially for Eugene and the other two, who had already been mentally brutalized by He Yu over and over again.

Just thinking about it gave them cardiac arrest.

He Yu looked innocent. “Really? But unless negotiations are involved, I generally prefer to speak only when I’m at least eighty percent certain.”

Wanrenzhan, Eugene, Zhen Xing: “......”

Audience: “......”

【Bullet Comments: “Having someone like this as a teammate is incredible. He can hard-carry the entire team, but holy shit he’s also infuriating.”】

【Bullet Comments: “Not just teammates! He tortures the audience too! Every single time, until the final moment, nobody knows what kind of twist He Yu is about to reveal next. This feeling is way too stimulating—I can barely handle it anymore!”】

【Bullet Comments: “His brain is already at step ninety-nine while his mouth refuses to say even step one. Then after confirming everything, he suddenly throws out the truth and makes everyone question their own intelligence...”】

It wasn’t just the audience questioning their intelligence.

Even Eugene and the others, who were top-tier experts inside the instance itself, were beginning to question their intelligence.

If he’d just explained earlier, they could have participated in the deductions instead of having the final answer smash directly into their faces.

Wanrenzhan’s nostrils were practically smoking as he glared at He Yu.

Zhen Xing took a deep breath. “Enough. That’s not the important part right now. The important part is the murderer.”

—This was just He Yu’s personality. What could they even do about it?

—It wasn’t like they could beat him up.

People getting hard-carried had to endure it!!

The Cafeteria Uncle’s body trembled slightly. Raising his blade toward the class monitor, he asked hoarsely:

“Why? Why did you hurt You Mo?!”

Hearing this, the class monitor raised his head and closed his eyes, wearing an expression that practically said “Do whatever you want.”

The Cafeteria Uncle crouched down and grabbed his collar, roaring:

“Are you going to talk or not?! If you don’t, I’ll slice you into pieces and make your life worse than death!”

The class monitor opened his eyes and sneered.

“It doesn’t matter whether I talk or not. You’re not going to let me die easily anyway.”

A crazed light flickered in his eyes.

“Is your daughter You Mo? I never intended to kill her. She insisted on following us to save people. Someone so weak still wanted to play hero, so I could only deal with her too.”

“You deserve to die—” The Cafeteria Uncle gritted out through clenched teeth.

He yanked violently on the class monitor’s collar until the boy’s face turned pale blue from suffocation.

The class monitor struggled to breathe but still curved his lips upward.

“Do you know what your daughter said before she died?”

The Cafeteria Uncle’s voice turned urgent. “What did she say?!”

The class monitor giggled strangely.

“But I’m not going to tell you. I’ll make sure you never know for the rest of your life. Hahaha.”

The Cafeteria Uncle completely broke down and tightened his grip further.

The Janitor immediately rushed over to stop him.

—This piece of trash absolutely could not be allowed to die so easily.

Suddenly, He Yu spoke.

“You’re a psychopath.”

Everyone froze.

The class monitor also looked toward He Yu, his eyes cold, dark, and full of hatred.

—He should have been able to leave successfully.

It was all because of He Yu!

Suddenly, the class monitor raised a finger and pointed at He Yu.

“Kill him! If you kill him, I’ll tell you everything about You Mo! I’ll tell you what she said!”

The Cafeteria Uncle froze.

Zhen Xing’s Rubik’s Cube instantly appeared in his hand as he stepped protectively beside He Yu, staring vigilantly at both the Cafeteria Uncle and the class monitor.

Wanrenzhan paused briefly before gritting his teeth as his axe appeared in his hand as well.

They genuinely suspected the Cafeteria Uncle might agree.

After all, his feelings toward his daughter ran unimaginably deep.

And compared to that—

he had only known He Yu for a short time.

But He Yu showed no concern at all. He merely laughed softly.

“I wasn’t insulting you. I was stating a fact. You’re a psychopath, and you’ve been one since childhood. Perhaps your environment had something to do with it?”

The class monitor stared at him viciously.

He Yu nodded. “Mm. Looks like I guessed correctly. Your family is wealthy and powerful, but your home environment was terrible. You’ve been a psychopath since childhood, wearing a mask to disguise yourself. That’s why your performance feels so naturally convincing that nobody can distinguish truth from falsehood.”

Looking at the class monitor, He Yu continued:

“Let me guess something else. When your family helped cover up what happened to Anna and You Mo, it wasn’t because they cared about you. It was because they cared about the family reputation.”

The class monitor’s expression finally changed.

“Excellent. Another correct guess.” He Yu’s voice turned soft and eerie. “That’s why your family didn’t take you away and didn’t protect you. They only care about their reputation, not you. When you disguise yourself, what you long for is becoming a disciplined, dazzlingly outstanding class monitor—not disappearing among the masses. That’s also because of your family, right?”

The class monitor’s fists clenched tightly, eyes icy cold.

He Yu nodded again.

“Continuing the deduction—you hid yourself for three months, found a scapegoat, and prepared to transfer away because your family wouldn’t help you. Everything had to be handled by yourself.”

“Shut up!” the class monitor roared furiously.

He struggled violently, trying to attack He Yu, but the Cafeteria Uncle suppressed him effortlessly with one hand.

He Yu continued calmly:

“As the mastermind, there’s no way you targeted Anna without a reason. You’re arrogant and deeply insecure. You chose to torture Anna and You Mo before hanging them in the old building...”

Suddenly, He Yu sharply locked eyes with the class monitor.

Their gazes collided.

Then He Yu abruptly changed direction mid-sentence—

“Anna rejected your confession.”

The sudden shift came too quickly, and He Yu’s tone was too certain.

The class monitor failed to react in time.

Every reaction appeared purely instinctive.

His entire face practically screamed—

How do you know that?!

He Yu had guessed correctly again.

The Eugene head tucked in He Yu’s arms went completely motionless.

Beside him, Zhen Xing and Wanrenzhan both looked mentally absent too...

【Bullet Comments: “HE JUST RECONSTRUCTED THE ENTIRE CASE?!”】

【Bullet Comments: “Holy shit! That’s terrifying! This guy’s deduction ability is horrifying.”】

【Bullet Comments: “And his interrogation style is absolutely chilling! The class monitor didn’t even say anything, yet He Yu already knows everything. Fucking terrifying.”】

He Yu said lightly:

“What a simple and ridiculous motive. You confessed to Anna and got rejected. Arrogant yet insecure, you became enraged from humiliation and joined others in tormenting Anna. You Mo was merely dragged into it.”

“She deserved it!” The class monitor’s eyes turned bloodshot. “What right did she have to reject me?! If she dared reject me, then I’d strip off her clothes and turn them into the dirtiest, cheapest sluts in the world!”

“No.” He Yu sneered coldly. “Anna and You Mo were the cleanest people here. You are the truly filthy garbage. Filthy from soul to body.”

The class monitor burst into manic laughter with bloodshot eyes.

“Haha! So what? Then kill me!”

He Yu stepped forward and lowered his gaze toward him.

“Not only will we kill you. I know you’re not afraid of death. For a psychopath like you, what’s so painful about dying?”

His voice became cold.

“But—we will expose every single thing you did to the public. We’ll tell everyone your identity. You will become your family’s eternal disgrace, and your entire family will be despised along with you.”

The class monitor’s expression changed dramatically, his face full of disbelief.

He Yu continued:

“The family that made you arrogant and insecure will despise you forever from now on. Those people who already looked down on you and ignored you will only hate you more and despise you more.”

“No—you can’t!!” the class monitor screamed hysterically.

This was his weak point.

This result was what he feared most.

Psychopaths were not afraid of death.

But even psychopaths had things they feared.

—and He Yu had struck directly at it.

Suddenly, the Cafeteria Uncle spoke.

“Teacher He Yu, please leave for a while.”

He intended to take revenge now.

He Yu raised a brow. “You don’t want to know what You Mo said before she died?”

The Cafeteria Uncle shook his head, his voice gentle.

“You were right. I understand You Mo. I know what she would say to me. As for what I don’t know...”

“...I’ll go ask her myself.”

So he would not be manipulated by the class monitor.

And he definitely would not attack He Yu.

Seeing this, He Yu nodded and left downstairs with the others, leaving the rooftop to the Cafeteria Uncle and the class monitor.

An hour later—

the Cafeteria Uncle’s voice came from the rooftop, and only then did the group return upstairs.

On the rooftop, only the Cafeteria Uncle remained.

He knelt weakly on one knee, supporting himself with his weapon.

Having finally taken revenge, his entire body carried an unprecedented sense of relief.

Seeing them come up, his gaze became unfocused. Smiling gently, he said softly:

“I think... I’m about to go see You Mo now. Teacher He Yu... thank you. Thank you, all of you.”
