It wasn't until the bear cub let out a warning roar that Cheng Shuang noticed the unusual atmosphere.

It wasn't quiet, but rather an indescribable cacophony!

The sound of horses' hooves echoed, their momentum was fierce!

She whistled and looked in the direction where the 'Referee Amurota's suspension whistle' had been thrown, just in time to see a herd of horses charging toward them and a strange mirrored arm rapidly retracting.

The whistle not only stopped, but also disappeared without a trace.

For the first time, the little girl felt the urge to curse. She glared at her bespectacled mother, who was oblivious to the impending disaster and secretly gloating, and gave her a hard knock on the forehead in exasperation.

"Are you stupid? Didn't you hear the whistle stop?"

As the centaurs, each with a hideous face, approached step by step, the bespectacled girl, whose facial scars began to throb, thought: ...Damn it! I completely forgot!

The centaur, with its grotesquely long limbs, clawed and tore with its arms, kicked and stomped with its legs, making its entire body a weapon. It could attack or defend, and it ferociously pounced on the man, bear, and ghost at the center.

They bared their teeth, and even a horse couldn't withstand a single bite.

The girl with glasses could already picture it as a skinny ghost being torn apart by countless teeth, and she froze.

"Little bear, throw it out!"

The little girl's exasperated voice rang in her ears, jolting the bespectacled woman back to reality. She dared not steal anything and quickly opened her palm, revealing a squeaking, glittering whistle inside.

Then, looking aggrieved, she explained, "I...I was afraid of losing it, so I picked it up for you!"

A dark figure appeared out of nowhere, snatched the whistle from the bespectacled woman's hand, and gracefully glided past the herd of horses to Cheng Shuang's side.

The girl with glasses wanted to clench her fist to stop it, but when she saw that not only Cheng Shuang and the giant bear were staring at it, but the dark-cloaked figure was also coldly locking onto it, she immediately wilted.

If the little girl hadn't sent the ghoul to retrieve the whistle, she would never have overlooked the bespectacled girl's ridiculous greed. Fortunately, the horses fell to the ground again, and even though the distance between them had shrunk to only two or three meters, the centaurs in the front row were still baring their teeth and roaring at them unwillingly. The crisis was finally temporarily averted.

Cheng Shuang rolled her eyes, too lazy to argue with the girl with glasses about such useless things. Now was not the time to play along with ghosts and monsters.

With a flick of her head, the little bear skillfully shoved the girl with glasses into the blood pit.

It really is a door!

Because she was upside down, the girl with glasses frantically flailed her limbs, while the little girl turned her head away, her face turning green, secretly relieved that she was wearing leggings under her dance skirt.

Suddenly, its movements stopped, and the entire ghost remained still for a long time without any change.

The bear cub pulled the bespectacled girl, who seemed to be frozen in time, back to reality and held her up in front of Cheng Shuang.

Apart from her slightly messy hair, the girl with glasses looked perfectly normal.

Cheng Shuang asked directly, "What's inside?"

The girl with glasses hurriedly covered her mouth and shook her head, her eyes still showing signs of shock.

It seems I can't say anything again.

The library, dance studio, restaurant, restrooms, playground—she had either experienced them or almost missed them; now, only unknown enclosed spaces and…

Teacher's office!

Cheng Shuang remembered that the class monitor had mentioned the question of who would be caught by the 'teacher' first. So far, she had only encountered monsters, not a single teacher. The office was an exception, as there seemed to be a 'teacher' in heels constantly pacing around, the heels making a rhythmic clicking sound.

So even the girl with glasses doesn't dare to make a sound, for fear of being caught by the 'teacher'?

This seemingly short period of time, with one movement and the other stillness, actually only lasts for ten minutes. Soon, the whistle's light begins to flash, and the time is up.

Seeing the towering centaurs blocking their way, Cheng Shuang had no way out and dragged the bespectacled girl into the blood pit.

The quiet office was bathed in sunlight, with not a single dark spot. Every corner was spotless, and even the smallest speck of dust could be seen in the light.

The windows here are different from the stained glass windows in the classrooms. They are bright and clean, with large, continuous panes that replace part of the walls. Although they look nice and grand, they make it easy for people in the corridor to see clearly into the offices.

As the dirtiest person and ghost in the office, they stood on the desk, like two small stains and marks, unable to move and feeling out of place.

There was no way around it; every movement left two pairs of tiny, bloody footprints.

The teddy bear cub in Cheng Shuang's arms had dirty feet, covered in oil and dirt, while the sullen monster perched on Cheng Shuang's head looked like an untainted hermit.

When the little girl's gaze fell upon it, the gloomy monster sighed deeply, helplessly spreading itself out into a flat pancake, transforming from a wizard's pointed hat into a beret.

Outside the door, there was the clattering of heels. Through the neatly arranged books and documents on the desk, one could vaguely see a figure outside the window, posing a constant threat of pushing the door open and entering.

Cheng Shuang made a quick decision: she spread a layer of tissues on the table, took off her blood-stained socks, wiped her feet on the tissues, and put her leather shoes back on.

The black leather shoes made a sound when they walked, and were much smaller than the bloody footprints.

Unfortunately, the bloodstains on the soles of the feet were already half-dried, and unless they were washed with water, they would easily leave traces.

As for the girl with glasses... the little girl pulled the ghost away after he took the opportunity to hug her waist and kill her, and said in a low voice with a forced smile, "I know you can turn yourself into a mirror, so covering your feet shouldn't be difficult!"

The girl with glasses scratched her head and said in a sweet, innocent way, "Oh, I forgot!"

Cheng Shuang's face darkened. She gave it a meaningful look, bent down and quickly wiped the footprints off the table with a tissue. She then tiptoed to a makeshift bookshelf to temporarily conceal herself and observe the office environment.

The office wasn't large; although it was as big as a rugged mountain compared to Cheng Shuang's petite stature, it was indeed a single-person office.

A table, a chair, and a teacup.

The cup was still steaming, and the aroma of tea wafted through the air, creating a peaceful and tranquil atmosphere in the context of the scene.

Unfortunately, what was lurking outside the door was not a real teacher, but a vengeful ghost poised to pounce and devour people.

The doorknob clicked.

Cheng Shuang immediately shrank back, her peach blossom eyes sharply fixed on the girl with glasses...

The bespectacled girl, who had been dawdling while mirroring the sole of the shoe, froze. Soon, she straightened up, quickened her mirroring speed, and, imitating the little girl, picked up the tissue she had deliberately left for her to wipe away the footprints. Then, she ran towards the bookshelf.

The tissue, due to inertia, floated under the table.

"Ah!" it exclaimed softly.

The door opened.

A low-heeled leather shoe stepped in.

The girl with glasses glanced at the table with a mixture of regret and anxiety. As the door opened fully, she didn't hesitate. She bent down and ran a few steps, nimbly hiding in the shadows between two books.

It stretched out its finger to Cheng Shuang's lips and made a silent hissing sound.

The tissue landed softly on the floor, footsteps approached, and the door clicked shut.

A long, thin shadow fell on the table, blocking out the warm light and leaving only darkness.
