The classroom was completely silent.

A mixture of red and white solid and liquid landed on the desk, then dripped and splashed onto the floor along the edge of the desk.

A strange smell permeated the air.

Xiao Cheng suddenly felt an inexplicable urge to argue with Teacher Liu.

But before she could speak, her throat suddenly tightened, as if something invisible was choking her.

She could feel her consciousness gradually fading, and in a daze, she saw a line of small words appear on the blackboard.

"I'm talking to you about the third school rule: do you understand the importance of respecting teachers?"

Damn it, is this how you show respect to your teachers?!

Similar to yesterday, the feeling of suffocation quickly disappeared, and air rushed back into her body. Xiao Cheng clutched her chest and coughed violently.

The bell rang suddenly, and Ms. Liu put down her pointer and, as if nothing had happened, said calmly to her, "Class has started. Don't waste time, go to your seat."

There was only one empty seat in the last row, by the window, right next to the trash can. When you got close, you could smell a strong stench of decay, like rotten plants that had been soaking in sewage for half a year before being dumped into a sewer that hadn't been cleaned for six months.

This can already be classified as a biological attack.

Xiao Cheng frowned, held her breath to minimize breathing, and reached out to push open the window. As fresh air rushed in, she finally felt a little better.

It's just very windy.

A dark, indistinct thing was swept away, and she turned her head in a daze, only to see her cheap deskmate's shiny bald head.

Xiao Cheng: "..." This is truly exceptionally clever.

My deskmate didn't say a word, maintained his upright posture, and mechanically pulled a hat out of the desk and put it on meticulously.

Noticing this, Teacher Liu on the podium threw down the piece of chalk and sternly reprimanded, "A very small number of students! If you don't study, others still need to!"

Xiao Cheng was afraid of triggering some school rules again, so she quickly opened her book and sat up straight. Fortunately, she glanced around and didn't see any strange prompts.

Teacher Liu seemed less irritable during class; at least he didn't pick up the blood-stained pointer again.

The text was just an ordinary article. Xiao Cheng felt it was somewhat familiar, but she couldn't remember where she had seen it before. She guessed she had learned it before entering the game, but as her memory faded, she forgot it as well.

She was sitting there, chin in hand, lost in thought, completely unaware that Teacher Liu had quietly walked up behind her.

"Please answer this question."

A soft, unnatural hand gently touched Xiao Cheng's shoulder. Startled, Xiao Cheng nearly jumped up from her seat and turned around abruptly, only to be met with Teacher Liu's face looming close to hers.

"Did you hear that?" she repeated in a sinister tone. "Stand up and answer this question."

Xiao Cheng hadn't heard what she had just asked at all, and opened her mouth in a blank expression: "Huh?" She asked uncertainly, "Wh...what question?"

Teacher Liu snorted coldly, "I didn't ask any questions just now, that's good, it seems you're still listening." Then she withdrew her hand and slowly walked towards the podium.

After finally making it to the end of get out of class, before Xiao Cheng could even breathe a sigh of relief, Teacher Liu picked up her pointer again and gently tapped the podium: "Class, don't rush off yet, I have something to say."

"I know some of you don't have a strong foundation, but even a slow bird can start flying; as long as you're willing to learn, your grades will eventually improve. But I don't see any effort from you! What's worse, your attitude is extremely unprofessional!"

Xiao Cheng: "..." Just say my name, teacher.

"The first mock exam is about to begin, and I cannot tolerate such a black sheep who drags down the average score of our entire class!" Teacher Liu said with great excitement.

"You know who I'm talking about! If you're still thinking about it, then come to me for extra lessons during evening self-study time!" The pointer slammed heavily on the podium, instantly sending wood chips flying.

Xiao Cheng nodded quickly, "I heard you, I heard you. It's okay if the students are hit, but the podium is innocent!"

Perhaps sensing her sincerity, Teacher Liu breathed a long sigh of relief, her tone gradually softening: "In the next class, we will do a composition exercise. That's all, get out of class dismissed."

As she put down her pointer, the students in the classroom all put away their textbooks and collapsed onto their desks like puppets with broken strings.

Soft, melodious music played from the black speaker above the blackboard. Teacher Liu stood quietly on the podium, her body gradually becoming ethereal, then resembling an old television screen with poor signal, flickering with chaotic black and white static.

It eventually disappeared from the spot.

Xiao Cheng turned to look at the students who had all fallen down, but instead of getting up, she tentatively nudged her deskmate.

There was no reaction, and the skin felt hard to the touch, like a lifeless puppet.

The break between classes was twenty minutes long. Xiao Cheng left her seat and quickly walked around the classroom.

Beside the podium, the student's body still lay there, blood dripping down the corner of the table and pooling on the floor.

Inside his desk, there was a hardcover diary, with a corner peeking out. Just as Xiao Cheng was about to reach for it, someone stopped him.

"Don't touch it." A flat female voice sounded behind her, "If you don't want to be mistaken for a thief."

Xiao Cheng was slightly taken aback, turned her head in confusion, and realized that it was the female student sitting in the second row.

She maintained an odd posture, her upper body slumped on the table, her head tilted upwards as if trying to stretch her neck out, making it look as if it were about to bend backwards.

“Don’t touch it,” she warned again. “The school’s punishment for thieves is quite severe.”

But this diary is arguably the only clue Xiao Cheng found here.

She thought for a moment, then turned to look at the corpse thoughtfully. She leaned down slightly and patted its shoulder sincerely: "Hello classmate, may I borrow your diary? I don't mean anything by it, I just want to admire your imagination."

Then she paused for a moment, as if she were really listening to his answer.

Of course, there can be no answer.

The female student let out a disdainful sneer, and was about to say something more when she saw Xiao Cheng nod seriously and emphasize to her as a matter of course, "You have to testify that he tacitly agreed."

Then he pulled out the diary.

The female student angrily began to curse, her voice so shrill it was unsettling, like fingernails scratching on a blackboard: "Thief! Thief!"

The two words echoed for a long time in the deathly silent classroom. Then the female student's neck began to swing, faster and faster, until it finally gave way and snapped at the root with a crack.

Her head rolled to Xiao Cheng's feet, and the gushing blood flowed onto the floor, leaving a line of words.

"Article Four of the school rules states that God gave you a mouth, and you actually used it to frame your classmates?"
