Liu Lin's death came suddenly. Last week, he was dining and chatting with us. In the blink of an eye, he became a lifeless body with just a phone call.

After the call ended, I sat there in a daze for a few minutes, not knowing what I was doing. Suddenly, it hit me that the person on the phone informed me to go and collect Liu Lin's body.

He was a loner with no family, and I was the only emergency contact he had left.

I tidied up and set off for the address he left behind.

Liu Lin died while working. He was a tester for haunted houses and made 500,000 yuan in just half a year. He was extravagant when we had meals together, and many people were envious at that time.

Who would have known that he would suddenly die in a haunted house?

I stood at the door, hesitating. The thought of going into a haunted house made me uneasy.

I called out a few times, but there was no response. When I tried calling that phone number again, no one answered. However, the door was open, emitting a creaking sound, which added to the horror.

Inside, it was very bright with good lighting. The light coming in from the tall buildings in front was unaffected.

But from the moment I stepped into this haunted house, I felt very uncomfortable. This place exuded an eerie atmosphere.

"Is anyone there?"

I called out and leaned inside.

No one responded, but a piece of clothing corner appeared in the corner of the wall. There was someone there, why weren't they acknowledging me?

I was a little angry at this person's impoliteness, so I walked forward, about to speak out, but the words I was about to say got stuck in my throat.

Liu Lin! His body was pressed against the wall, eyes wide open, with tears of blood flowing down his pale face.

My heart skipped a beat, and I was so scared that I squatted down on the ground.

What the hell, whose prank is this!

He was still standing there, his body already stiff.

There was no one else in this room, only Liu Lin's body standing here in a bizarre posture.

It's too eerie!

I ran to the door, but where was the door? Where did it go?

It couldn't be that I remembered wrong. The door was clearly in this position. How could it disappear?

Calm down, calm down! I searched the whole room in a frenzy, but the vanished door didn't come back.

The air was stifling, and even though the windows were tightly closed, the curtains were mysteriously swaying, like white ghostly shadows.

I couldn't leave, and through the window, I saw a pale landscape outside, as if this building was standing alone on a deserted island.

When I arrived, I saw towering skyscrapers and bustling streets, but they had all disappeared.

A whiteboard appeared where the door used to be, with bright red words on it: Haunted House Tester's Guidelines.
