Review Detail of XiaFu in I Stayed At Home For A Century, When I Emerged I Was Invincible

I truly like this novel. Some ppl aren't satisfied with the mc being so passive and secretive, but that is exactly what drew me in. Furthermore the world building is good and the storytelling is funny. I like it. (PS don't know if this counts as spoiler: I personally think he's not even trying to be secretive most of the time ... It's just in the beginning when he was actually weak.)
