My best friend Meimei and I grew up together since we were young.

During the Qingming Festival holiday, she came to visit me.

We agreed to go to Happy Valley together.

As soon as we entered the amusement park, we saw a huge sign.

On it was written a warning message in bright red paint.

Rule One: No loud screaming on the rides.

Rule Two: Stay away from NPCs wearing red clothes.

Rule Three: Play at least five attractions before leaving.

Rule Four: Always pay attention to the sub-rules throughout the amusement park, as they may save your life.

The words were crooked and twisted, and when seen on a cloudy day, they gave a strange sense of gloom.

Meimei asked me excitedly,

"Is this the Qingming-themed activity in Happy Valley? It's quite thrilling. I felt a chill coming from the soles of my feet as soon as we entered. Let's go in and play."

She pulled me inside.

Instinctively, I turned my head to look at the entrance.

The outside seemed to be engulfed in dense fog, and I couldn't see any scenes at all.
