Please Recommend Some Good Novels. If You Like Narcissus, It Can Be Read by Both Men and Women.

I really like this kind of thing. It can be a split personality, the intersection of the future and the present, or the splitting of the soul and body of cultivating immortals. It can be any subject, interstellar, cultivating immortals, restraint, fantasy, western fantasy, anything. Please recommend it. I hope the protagonist is not the Virgin.
