Terror Resurrection: Another "I"

My name is Baize, and I have the same name as the legendary beast "Bai Ze" in the world where I live. But I was a pure atheist until— Late one night, I woke up from a nightmare and found myself leaning against the head of the bed.

My face. I touched myself and seemed to understand something. Forgot to mention, my room... Has no mirror at all. This novel and its characters are purely fictitious.
