actually this is a remake from the " i am the great immortal", in the first manwha the disciple is his lover, but originally she is his killer and YEAH believe me , this should be better than the first manwha but still the worst urban life i have read in my life THE WORST, i can even explain a little, here world building is trash, all the people on the novel only want to kill mc, no matter what, even if mc save people they want to kill him, and yes he didnt get his revenge against his disciple yet on the novel(at least from what i remember) so bear in mind.
The plot start with his gf betryaing him, then leaving him, ofc faceslap time then she regrets,between that he meets the generic cop flower that is the righteous kind, then for no reason she handcuffed him then when a ghost comes she leave him to die,ofc he doesnt and still saves her, then later as every women on this series she start to disdain mc and treat him as a pussy, because he didnt want to break the law( remember she was supossed to be righteous) then mc save her life and leave her crying and she regrets, then mc leave the city to meet his fiance(that disdain him and regrets later again),then his highschool mate that disdain him and regret, then a idol that do the same thing then u ask me, its done? The anwer is no this will repeat at least 20-30 times its not like it stop later either, so yeah if u like brain dead world building and annoying people this is for u, dont forget this is a remake following the novel and one more example , later the main plot will revolve in "death game" where people goes while sleeping then mc AND random people have to climb stairs while carrying weight, mc start to help people to carry so they can survive, one of the girls order him " hey you! I order you carry this for me!" Then he says no, want know what happens then? ALL the people want him to die because he said no..... Exactly that and reading this novel i did read the word "disdain" more than all the hundreds novels i did read before.
