I Heard I'm a Grave Robber

Police: Now, take a good look at this photo. Does it look familiar?

Protagonist: Is this a hole in the ground? I've never seen it before. What kind of hole is it?

Police: Look at this one again. Do you recognize it?

Protagonist: This, this is a spider? Sorry, I'm clueless about biology. I can't tell what species it is.

Police: Why are you stuttering? Mei Qian, you heinous grave robber, confess your crimes!

Mei Qian never imagined that his fanfiction and original grave-robbing novels would be linked to ancient tombs in a parallel universe. The key is that he's been transported, and he can't explain where he was a few years ago. How can he break this deadlock?
