Corpse Ancestor System: Taking Lin Jiu as My Disciple from the Start

I think this setting is quite interesting. It combines system elements with the familiar classic image of Uncle Jiu, which brings a sense of freshness. But I'm thinking that it would be better if the characters could be given more unique characteristics - for example, in addition to the identity of the "Corpse Ancestor", the protagonist could also hide some of his own persistence, so that his attitude changes could be more subtle. This way the characters will stand up more. Polish the details a bit. Personally, everyone has different preferences.
