This book is Black Fire's first attempt at a fantasy rule-based novel. The rules will be revealed little by little, so please read patiently.
Dai Lin became a surgeon at a strange hospital.
Here, what is treated is not disease, but all kinds of terrifying and mysterious curses! It is divided into the Resentful Spirit Family, the Fierce Ghost Family, the Evil Ghost Family, the Evil Spirit Family, and the mysterious Demon Family, etc...
A strange hospital with puzzling rules:
First, I believe this hospital is called Hospital No. 444, not Hospital No. 666

Fourth, all doctors in the hospital wear white masks. If you see doctors wearing red masks, please ignore them and don't let them find out that you can see them.
