The cover is my own fault, I don't know if it's good or not.
Ling Chen is a snake spirit disease, suffering from the second grade disease, and has officially given up treatment since the age of fifteen. He became a vampire at the age of nineteen, insisted on killing his younger sister, Mary Sue, battled wits and courage with the system, and made a lifelong good friend, Hualing.

Ps: Wen Chen had the system when he was a child. The system told him that the world was a book, and also told him the general content and settings of the book, so he knew some things, and there were some things that the system hid from him, so he also had many things he didn't understand.
