Review Detail of SupremeKaz in I Reincarnated as I have got One Permanent Ability per Day

For my Review I should say that the mac personality here is everchanging because there is one time he pathetic wimp then in another chapter he release strong bloodlust despite killing few And the mc is so op in the start but still act like a wimp and his power sometime doesnt work despite him mastering it cause of intant mastery So my evaluation of the mc is he is pathetically Nerfed Then the story jump places from time to time like what the f*ck can u atlleast show something interesting from time time rather than boring and if you gonna write filler at least add some element to it like comedy , drama or exciting fight or my favorite the badass moment And for the world development/bckground at least think about what you add before writing it andthink of the plot(if you have one) and how it can affect it not just write it for the sudden inspiration because it will jumble it making it hard to write more Character development I think there isnt because it still have few chapter and I hope to see more changes especially mc personality And can unnerf MC please
