Horror Movie Set: This extra is too good at playing the tricks.

Chapter 21 Bad kids aren't allowed to tattle, good kids aren't allowed to sue.

A roaring sound came from above, and dust fell in a flurry, blinding Zhang Kai.

Before he could even recover from the question of "why the ceiling suddenly started falling dust," Lu Dan had already grabbed Zhang Kai by the collar of his school uniform and darted out like a cheetah, dragging him towards the stairwell.

The gecko monster, pinned to the ground by its "roommate," let out a deafening roar. It clearly hadn't expected that the dark figure that had been fighting it to the death just moments before would, upon seeing the security guard run away, turn into a puddle of fluid without any sense of martial spirit and "whoosh" back to Lu Dan's feet.

The gecko monster missed its target, its claws carving three deep grooves in the ground. The figure in the security guard uniform had already disappeared around the corner of the stairs.

The gecko monster followed closely behind, its anger driving it to its maximum speed.

"Quick, quick, uncle, it's going to bite my butt!" Zhang Kai was dragged along and stumbled, but he still couldn't help but give a completely unhelpful explanation.

Lu Dan ignored him completely, his gaze fixed on the entrance on the fourth floor.

The cement wall that was originally painted with a strange smiling face and had the words "Bad kids are not allowed to tattle" written on it now had a huge gap in the middle that was big enough for two people to pass through.

Broken bricks were scattered everywhere, and exposed steel bars looked like a gaping mouth waiting to be fed.

Lu Dan gave a low shout in his heart, pushed off with his feet, and pulled Zhang Kai into the gap together.

The moment the two landed, a sizzling sound came from behind them, like a construction site turned upside down—countless broken bricks flew up automatically, and steel bars seemed to have living tentacles, intertwining themselves again. In the blink of an eye, the huge gap disappeared.

"Thump!"

The gecko, which had been chasing after it, crashed headfirst into the newly restored wall.

Through the thick cement wall, Lu Dan could hear the thing's screams as it crashed into the wall, its head bleeding profusely, and the ear-piercing noise of its claws scratching at the wall.

"Bad kid, don't come up here!"

This time, the large red characters on the wall twisted and changed their meaning, as if mocking the monster downstairs.

Lu Dan released Zhang Kai's hand and leaned against the wall, panting heavily.

This coordinated attack was practically dancing on the Grim Reaper's scythe.

He quickly pulled out his patrol log from his pocket, the pen flying across the page: [4th floor, everything normal.]

......

The world outside, the office of the Dean of Students.

The utility knife, worth 300 points, seemed to have completed its mission after piercing the wall, shattering into pieces and eventually dissipating into black smoke.

Lin Xiaoxiao looked at her empty palms, her heart aching so much that her lips twitched.

That's 300 points! Enough to buy three lives, just to open a door?

But when she saw the line of words appear on the paper in her hand, she knew the money was well spent.

"Each takes what they need, and neither owes the other anything."

Lin Xiaoxiao muttered something under her breath. Before the terrifying headmaster of studies arrived, she quickly cleaned up the traces at the scene and then slipped back to the counseling room.

She knocked on the door, and Bao Ping stepped forward cautiously, asking, "Who is it?"

Lin Xiaoxiao replied irritably, "Who else could it be? It's me."

When the door opened, Bao Ping was standing guard at the entrance like a door god, holding a wrench. Li Mu and Su Ke were still sitting on the sofa in the same position as before.

When Bao Ping saw Lin Xiaoxiao return, his eyes lit up instantly. Just as he was about to ask something, Lin Xiaoxiao gave him an "OK" sign.

Bao Ping, being an old hand, immediately swallowed back the words he was about to say and instead shouted, "Hey, Teacher Lin, I've checked this exhaust fan, there's nothing wrong with it."

Lin Xiaoxiao ignored his dramatic performance and went straight to Su Ke, sitting down again with a smile that was more genuine than before—after all, she had just spent 300 points, and it would be a waste of her money if she didn't get some useful information out of him.

Su Ke's voice trembled suddenly. She raised her head, and fear appeared in her previously empty eyes.

"Teacher, did you hear that too?"

She lowered her voice, as if afraid of disturbing something: "That's the sound of the head of discipline grinding. He's grinding... those disobedient bad kids."

......

The Otherworld, Building B, 4th floor.

The corridors here are completely different from those downstairs.

If the area downstairs is an abandoned horror movie set, then this place is an unfinished purgatory.

The ground was covered with a thick layer of dust, leaving clear footprints with every step. The walls were unpainted, exposing the grayish-white bricks, which had a texture reminiscent of human skin.

In the corresponding world psychological counseling room location, hangs the check-in machine that Lu Dan had been searching for half the night.

This machine looks older than the one in Building A, with rust on its surface and a few dry hairs stuck to it.

Lu Dan glanced at his watch: 11:59, a race against time.

He took out a yellowed card and inserted it into the card slot. The gears turned, and the red light turned green.

The crisp mechanical sound sounded like heavenly music to him.

The patrol mission was completed at the last minute.

Lu Dan breathed a sigh of relief and had just put away the card when he was tugged.

Zhang Kai, standing next to him, didn't celebrate loudly as usual. The guy had his head down, and his usually smiling face was now hidden in the shadows, so his expression couldn't be seen.

He pointed to the end of the corridor, where there was a very conspicuous mahogany door with a gleaming brass plaque hanging on the door frame: [Department of Education].

On this dusty and dilapidated fourth floor, this door is so clean it seems to belong to another world.

"Uncle, come with me."

Zhang Kai's voice was very soft, completely lacking the youthful spirit he had before, instead conveying a heaviness and deathly stillness that was incongruous with his age.

Lu Dan raised an eyebrow and did not refuse.

Now that this patrol is temporarily complete, the rest of the time is free time to explore the storyline.

And his intuition told him that this hot-blooded idiot was about to lay his cards on the table.

The two walked one after the other down the deathly silent corridor.

The closer you get to that door, the lower the temperature gets.

Lu Dan could feel as if countless resentments were piling up and slowly surging towards him.

Reaching the door, Zhang Kai stopped. He placed his hand on the doorknob but didn't turn it. His other hand trembled slightly as he pulled something else from his pocket—half a crumpled pink letter, which, together with the half Lu Dan had found on the third floor, could be pieced together to form a complete page.

Lu Dan looked at the half-sheet of paper, his eyes flickering slightly.

really.

Zhang Kai took a deep breath, as if he had made a decision that would shatter him to pieces. He turned his head, his once clear eyes now bloodshot, and a smile that looked more like a grimace stretched across his lips.

"Uncle, I really didn't want you to get involved in this..." Zhang Kai's voice was hoarse, with a hint of sobs, "because no one who walks through this door ever comes out alive. But I really have no other choice. Maybe... maybe only the security guards can pass through this door to hell."

Lu Dan subconsciously took a half step back.

Could it be that this kid has been using him all along?

He looked at the half-finished love letter in Zhang Kai's hand...
