Yao Jun Da Ren

Framed for the sudden death of her household's master and buried alive, Bai Jinyue wakes as a vampire. Thirteen centuries later she is thrown into Huantian, a continent shared by humans, demons and immortals, with no way back. A serpent demon with mismatched eyes, Jiu Yu, takes her in, and the two go looking for the Flowing Light Mirror — the only thing that can send her back.
