When Ling Feng opens his eyes, he finds himself in an unfamiliar place, with no memory of who he is. A girl who suddenly appears, Bai Ruoxi, tells him that he is dead and that this is a world of the reborn: the City of the Dead. It is a place filled with slaughter and secrets.
All the reborn are searching for the truth about this world. Who created the City of the Dead? Why were they chosen to come here? Why must they fight all kinds of undead...? To uncover the world's secrets and recover his memories, Ling Feng repeatedly challenges the order of the City of the Dead. With his companions' help, he narrowly escapes danger time and again. As they draw ever closer to the truth, its cruel revelations bring them to the brink of despair, yet also allow them to save one another.
