After a biological disaster called the "Red Mist" swept across the world, the earth was occupied by the twisted crystal monster "Phosphorus Beast", and the surviving humans huddled in the last shelter and struggled to survive. The lifeline of Shelter 79, the water purification system, is about to collapse. The only hope is to go to an abandoned research facility surrounded by phosphorus beasts to retrieve key replacement parts.
Scavenger Lin Jingxuan, a usually taciturn young man, resolutely took on this narrow escape mission in order to save his seriously ill sister in the shelter. He formed a temporary team with experienced veterans, nervous technicians and calm doctors, and stepped into the dead city filled with red mist.
However, as the journey progresses, Lin Jingxuan discovers that his unusual calmness and special "resistance" to the red mist are not as simple as luck. A shocking secret about himself and the origin of the red mist is hidden at the end of this mission. He must face his distorted past and unpredictable future while saving his homeland.
