The red mist descends and civilization collapses. The city becomes a hell, and those who inhale it may fall into eternal sleep, or mutate into a "breeding ground" for monsters that only know hunger and thirst. Su Zhao, an ordinary power plant worker, discovered that he had become an alien after a strange coma. He could sense the fatal frequency in the red mist and was one of the few special cases that could survive.
He was taken in by the rescue organization "Firefly", but he witnessed his best friend Zhen Mingxuan being swallowed by the red mist before his eyes, losing control and mutating. Su Zhao personally ended the suffering brothers, sealed his heart from then on, and turned into a "mourner" who only knew killing, burying countless monsters with a blood-stained dagger.
However, there is a turbulent undercurrent beneath the calm facade. The mysterious organization "Monkey Face" calls him the "key" to unlock the truth; the "Light" suspended in the sky regards him as an anomaly that disrupts the rules; and the "Firefly" who looks like a savior, its chief scientist Xing Geyuan seems to have already understood everything, and there is a core secret called "Anchor Point" hidden behind it.
As various forces compete, the red mist crisis escalates again. Su Zhao is forced to embark on a cruel journey to find the truth. In this scarlet wasteland, he must face the pain of the past and uncover the origin of his abilities, so that he can find the glimmering road hidden in despair and find out whether he is the terminator of the apocalypse or the starter of a more terrifying disaster...
