I think it's about how infinite mana repeats same thing again and again...I read 200 chapters and left cuz mc had no personality and the plot was always repeating itself again and again. I know new elements were added like cultivation system but that wasn't interesting. but this novel gives accurate description of power, like how time related abilities work. but does infinite mana in apocalypse get good after 200 chapters? or the plot is repeating??
