Seven-year-old Lin Xiaoxing was squatting in the yard playing in the mud when a strange red light fell from the sky. He was forcibly involved in a world of strange stories with rules and a mortality rate of 99%. There is no warmth here, only cold rules and fatal traps everywhere. If the participants are not careful, they will be swallowed up by the strange existence in the ghost story. The other participants were all adults, and they were trembling with fear when faced with the wall full of strange rules. Only Lin Xiaoxing relied on the simplicity and intuition of a child to solve one dead end after another by mistake.
