Late at night during a heavy rainstorm, Shiwa Village, a remote village in the north, together with its 217 people, was completely swallowed up by a strange black mist, and fell into a desperate mist where vegetation grew wildly and ferocious beasts surrounded it.
The only hope is the protagonist Li Xiaohua's old mobile phone that is running low on battery - it can receive broken survival warnings, but it may become completely silent at any time.
From the initial collapse of panic and internal fighting among people, to being condensed into a survival community by Li Xiaohua, the light and darkness of human nature take turns in the desperate situation.
Should we lead the remaining villagers to rebuild order and revive civilization, or will they lead them to irreversible destruction under the cruel test of nature and human nature?
A journey of survival in the wilderness with life as a bet, a desperate journey destined to tragedy, begins here.
