I really agree with this review, not going to add another bad ratings for the author but this sums up what I think about it, also to add something the MC has some progress on his morality and character multiple times in the story and then the author resets it back to zero constantly. I stopped reading the story in 550, where the MC became a totally psychotic power thirsty killer who will murder anyone even if there were some alternatives to killing certain people which were established by the author in previous chapters.
