He didnt spend his whole life tho? He inherited it from his father and isekaid in his 20s. He also took over the Central Planes because he was furious about losing his lover and again he was in his mid 20s by then. Everything hes done if you payed attention is so he can be with the woman he loves. His top priority by a LONG SHOT has always been his lover and if you also noticed he had retainers in his sect that were as if not more capable of handling affairs in his sect. He glossed over it because because if you noticed during the small time he was still in murim everyone he was close to was capable and they literally let him go off on his own to find his lover cuz they understood how much she meant to him. The entire story is literally about a man who lost his lover and is willing to do anything to be with her and make her happy. Also no one is inconsistent, theyre GROWING as individuals. Aka character growth??? Cant tell if ur serious or not but if its ragebait for having low media literacy then it worked.
Art is good but everything else is boring! All the characters are inconsistent in personality and motivation. Plots are introduced and immediately solved or ignored. MC doesn't seem to care about ANY of the other people he left behind in his old world or the organization that he was leading. Ya know, the one that he probably spent his whole life building and working towards? Yeah, that one. Things happen on screen or in an instant and we are given no clue as to how it happened or was even possible given the circumstances. Story might as well have been written by a 13 yr old.
