The apocalypse descended beneath a blood-red sky, bringing humanity to the brink of extinction.
Only this city, famous for its springs, became an island of survivors thanks to its unusual water. But the healthy all died suddenly, leaving only a handful of frail people to cling to life.
Fang Yang, a timid deliveryman, survived the early days of the apocalypse in an underground storeroom, living off a roomful of canned food.
All he wanted was to go home and find his mother. Instead, he unexpectedly met Cai Yuhan, a doctor, and befriended Shen Yifan, the miserable "crown prince" of an evil organization.
Fang Yang sharpened his knife and loaded his gun.
He could no longer be a weakling struggling just to survive. He would avenge his mother, fight to secure a peaceful future for Cai Yuhan, and seize the throne of this isolated city for Shen Yifan.
Doctor Cai Yuhan would dedicate herself to uncovering the disaster's secrets. Shen Yifan would shoulder the mission of preserving and reviving human civilization.
As for Fang Yang, he remained quietly in the background.
Everything he did was simply to let his beloved shine like a light and his brother become king.
