Mu An, eldest daughter of the Mu family, possesses every kind of supernatural power, enough to destroy the world. She also lives with a world that could tear her apart at any moment: severe depression and dissociative identity disorder. By day, she is an optimistic girl doing her best to heal her wounds. At night, or when she is on the brink of death, her second personality, Xu Yuanmeng, awakens, bloodthirsty and cold, ready to fight her way through a river of blood to protect those she cares about.
The apocalypse arrives, and supernatural powers awaken. She reunites with her childhood friend Mu Fan and gathers her closest companions, all wearing colorful dolphin pendants: the young lady of the Xia family, an heir to a military district, a vampire outcast, and friends from the orphanage. Fighting side by side, they carve a path through mountains of corpses. They think that defeating the Zombie King will bring a new dawn...
Yet the eerie legend of the “Headless City” spreads across the Central Plains, and a cliff transforms into the “Demon Cave of a Thousand Eyes,” devouring those who investigate. Beyond the frozen Antarctic Wall, the mutterings of the dying bring down a calamity. And some awaken from death, bearing the horrifying truth of the “inheritance.”
As a thousand eyes watch and the ice wall crumbles, the “God of Slaughter” within Mu An spirals completely out of control. Is the world they saved heading toward an even deeper nightmare? Can the dolphin pendants around their necks hold together this crumbling world and the hearts of its people?
