In a wasteland world brought on by the apocalypse, a genetic virus turns humans into mutants, while an ancient vampire bloodline awakens. Su Hanzhou, a seemingly mild-mannered botanist, is in truth a pure-blood prince hiding in human society. When his laboratory is razed by warlord Ye Xiao and the assistant he regarded as family is killed, Su Hanzhou drops his disguise and uses his twin bloodlines as his golden finger to return to a parallel timeline a hundred years earlier, when warlords divided the land.
There, he becomes a disgraced noble in exile, with only one cursed city as his territory: a lawless land where vampires and humans live together. The city is full of strange dangers, while warlords outside keep their eyes fixed on it. Using the scientific knowledge from his previous life and the supernatural abilities of a vampire, Su Hanzhou begins a lordly revival through a crushing technological advantage.
Yet behind this century-old timeline lies the truth of the massacre that destroyed his family in his previous life. A warlord woman who can manipulate other people's romantic feelings, an ancient organization coveting his bloodline, and a mysterious girlfriend who seems to know everything... As Su Hanzhou heals his territory and builds his power day by day, he gradually uncovers a shocking conspiracy.
