Review Detail of SpEcTEr_NiM in The Second Coming of Gluttony, the First of Vainglory

my review is low because it's true the mc is op because of og mc skill and additional skill he got but the story development really low the mc said he KNOW the story but like some comments here he act sometimes not like he know he's gf come from the other side but he didn't know the story it's suck I mean ok you change the mc personality body before he go to paradise but why the story development like that I only reach chapter 20 but it's enough for mo to tell that the author only changed little things and copyright everything from original novel😞😞😡
