A bloody invitation with a twisted smile on it dragged Lin Mo and nineteen strangers into a death game called "Seven Days of Purgatory."
On the carousel in the abandoned amusement park, those who stare into the eyes of the black horse will be assimilated; the smiling mask deep in the haunted house hides the truth about the fire ten years ago; when the clock strikes twelve o'clock at midnight, the shadowless "player" will show its fangs...
"Surviving to the last moment can reset your life."
Behind this temptation are the fatal rules that are updated every night, the suddenly distorted faces of the companions when they turn around, and the "them" who hide in the dark and share their appearance with the participants.
Lin Mo soon discovered that this game was never randomly selected - the fate of the twenty participants had been tightly tied in the amusement park fire that killed seven people ten years ago. When the smiley mask reflected his rotten face, and when the rules paper surfaced his forgotten memories, he finally understood: the so-called "resetting life" is just using a new purgatory to pay for old sins.
The seven-day countdown has started, and every second is devouring lives. Will you become prey to the rules, or will you tear them apart and find a way out? Lin Mo clenched his blood-stained mask, behind him were "them" pressing closer and closer, and in front of him were rule cards filled with lies - this purgatory never lasts longer than seven days.
