Tomb Raiding: My Enemy Is a God

[Tomb-Raiding Notes fanfic + no female lead + no System, set after Little Brother enters the Bronze Gate] I'm not very good at writing blurbs. My name is Zhou Mu. I'm a transmigrator, a miserable high school student who transmigrated without ever having read Tomb-Raiding Notes. As soon as I arrived, my entire family was murdered. People in the underworld said it was Dumb Zhang, so I gained an enemy. Later, I discovered that my real enemy was someone else. He said his name was King Mu of Zhou, and that I was his reincarnation. He wanted to take over my body. There's also a bunch of people surnamed Wang fighting it out with an organization called the Nine Gates. Anyway, my new life is pretty eventful.
