At this moment, Yu Yu's face was extremely ugly. The young nurse next to her had fainted out of fright. Yu Yu could only hold her waist and barely maintain his body shape.

I don't know when, but I heard a few sounds of locks being opened one after another. The sound came from far away and slowly reached my ears.

Yu Yu thought to himself that something was wrong and started to get nervous.

Beads of cold sweat oozed out of her forehead. She supported the girl next to her with one hand and reached for the cell phone in her pocket with the other hand.

In fact, Yu Yu lied to the young nurse. The fundamental reason why the lights on the fourth floor were not turned on was not to take care of those sensitive patients.

But it’s because…the lights on the fourth floor have never been on.

No matter how many times I changed the light bulb, it would blow up for no reason. The electrician came to check on it numerous times, and each time he would silently shake his head and say he couldn't find the problem.

His fingertips were so cold that they were a little stiff. After struggling to light up the screen, Yu Yu quickly turned on the flashlight.

The lights came on, and the bright white light illuminated the situation in the corridor, but the scene in front of him almost made Yu Yu's heart stop.

In the long and winding corridor, doors were opened one by one. The patient was standing strangely at the door with half of her body turned sideways. Her dark blue hospital gown stood out in the darkness. The group of people stared at her with sinister eyes, with the same terrifying smile on their lips.

Yu Yu's pupils trembled violently, and he and the young nurse beside him fell to the ground, staring at the scene in front of them in disbelief.

"Is this... an illusion?"

As if she had anticipated something, her body suddenly stiffened. She raised her cell phone tremblingly and shone it towards the door next to her.

Sure enough, the middle-aged man who was in the room at the beginning was also standing at the door, staring at her expressionlessly.

The light shone on his pale, bloodless face. His eyes were expressionless, like a corpse without any breath.

Seeing Yu Yu looking over, the middle-aged man suddenly grinned, blood trickled out from the corner of his mouth and dripped onto the ground.

“Tick-tock…tick-tock…”

Yu Yu only felt that the sticky blood seemed to splash on his hands. He was shaking a little while holding the phone, and closed his eyes and silently said that this was all an illusion.

"It's an illusion...it's an illusion."

These wards are locked, and the patients can't open them. They can't break free from their restraints, so they are all fake.

She must have been working too long these days and had hallucinations.

On the other side, the young nurse who had fainted finally woke up. She opened her eyes dazedly. When she saw the horrible scene in front of her, her pupils shrank, and her eyes rolled back and she fainted again in an instant.

“…”

Yu Yu knew that this was not a solution, so she made up her mind, gritted her teeth, picked up the little nurse, and planned to go down the survival stairs in the opposite direction.

But just as she was about to move, a cold, rough hand suddenly grabbed her wrist. The hand was as cold as thousand-year-old iron, and it seeped through the clothes and into her bones.

In an instant, all the blood in Yu Yu's body froze.

"Bang——" the cell phone fell to the ground.

She stared down at her wrist, and her white coat was stained with blood. Everything reminded her that this was not an illusion.

Under the dual stimulation of vision and hearing, Yu Yu could no longer hold back and screamed with a pale face: "Ah——!!"

But she forced herself to remain clear-headed. She couldn't faint. The young nurse beside her was still unconscious. She couldn't just leave her here like that!

She swallowed and realized that the middle-aged man was just grabbing her and not causing any substantial harm, so she gradually calmed down.

Damn, they are not real ghosts, and they are all patients. I have been treating mental patients for so many years and I have encountered all kinds of situations.

Yu Yu comforted herself in this way.

But then, the light at the other end of the corridor came on, and a black figure slowly walked towards this side.

The black shadow was blurry but very tall, almost touching the ceiling. It walked crookedly like a child who had just learned to walk. Its twisted figure looked like the god of death from hell.

Yu Yu got goosebumps all over his body and stared at the black shadow in disbelief.

Could it be that...what I say will come true?

Every time the black shadow passed a door, the patient at the door would slowly kneel down and kowtow his head heavily on the ground, looking so pious as if he was worshipping a god.

But what kind of god is this...

This is a real devil.

Yu Yu’s face was as pale as a dead person and his legs were shaking.

The black shadow was getting closer and closer, and the originally blurry figure became clear the moment it got closer.

But when she saw the ghost, her face suddenly froze and her throat seemed to be blocked by something.

"you……"

The ghost stared down at her, his eyes fell on the young nurse behind him, and opened his mouth as if he wanted to say something.

But suddenly, a beam of blinding light came from behind Yu Yu.

The bright light shot straight towards the black shadow, and the black shadow paused, as if raising its head to look towards the light source.

But then, it seemed to sense something was wrong, its aura became agitated for a moment, and then it disappeared from Yu Yu's sight in the blink of an eye.

Yu Yu was still sitting there in a daze until a familiar female voice sounded in his ears.

"Sister Yu."

The voice instantly awakened her thoughts. She turned around and saw Yu Li standing not far away with a mobile phone in her hand and a folder in the other.

"...Yu Li?" She called out softly, her voice a little uncertain.

Hearing the sound, the girl hurried over. When she saw their miserable appearance, she frowned and her eyes were full of worry: "What happened to you? Why did one of you faint?"

Yu Yu opened her mouth, "You didn't see..."

But when she turned around again, she saw that the corridor had returned to its previous state. There were no patients or ghosts, and even the middle-aged man next to her had disappeared at some point.

Yu Yu was startled and quickly checked his sleeves, which were still clean and empty.

Even Yu Li looked puzzled, "What did you see?"

She didn't see it either? Was it really an illusion?

"……nothing."

Yu Yu was a little absent-minded, looking at the ground, not knowing what he was thinking about.

She looked at Yu Li: "By the way, why are you on the fourth floor?"

Yu Li gestured to the document in her hand and said, "I just came down from the dean's office. When I passed the fourth floor, I heard screams and decided to come over to take a look."

Yu Yu nodded, wiped the sweat from his forehead, took back the flashlight and tried it, but unexpectedly the flashlight returned to normal.

She helped Xiao Chen up, and turned around to see Yu Li staring at somewhere.

"What's wrong? What are you looking at?"

Yu Li withdrew her gaze and smiled when she heard that.

"nothing."

She was just thinking that the ghost that just escaped... seemed a bit like Yu Yu.
