Crazy! Being a Zombie in a Vampire World

Crazy! The bad news is that I traveled through time. The good news is that I'm an orphan. The bad news is that this world is actually completely occupied by TM vampires, including Eastern China. The good news is that my blood is relatively rare, so I temporarily became a high-level blood pack, working as a teacher and part-time researcher in a vampire school. The bad news is that there's a baron who's always trying to eat me. The good news is that I accidentally cut my finger on a crystal skull and turned into a zombie. Yes, they are the kind of zombies in ancient Chinese myths and legends. So, the food chain reversed. So high! I seem to like biting vampires, and suddenly I understand how happy they once were!
