Yinshandu

Three hundred years ago, "ominous" rain fell from the sky. A strange black mist spread from the Yin Mountains in the west, swallowing up a territory of three thousand miles in radius overnight. In the dark fog, the rules collapsed and cause and effect hung upside down. If a living person goes in, he may die because he steps on his own shadow. Maybe his soul was taken away because he agreed to the greetings from the paper man on the roadside. Those who go in never come out again. The black mist continues to expand. Until, the first person comes back alive!
