I remember it is about a MC who is a doctor with his uncle wandering. MC's grandfather is an excellent doctor, who died trying to cure a daughter of a influential family, his last words were "power is everything". Then MC and uncle got kicked out of their family who hoards bottom half of the doc's manual of gramps, MC has top half. Then after some shit, MC became leader of an all female sect and a dragon girl, which he enjoyed accidentally groping. MC seems like a Donkan MC... Iirc i dropped it cuz it combined 2 things i hate, generic xianxias and Jap beta Donkan MC. Now I got bored and wanna just read it.
