Without spoiling anything... The good: The battles and spectacle are good, bloody/gory battles for an action/revenge story make a good combination, author uses flashbacks to flesh out characters before and after a fight which I've seen work sucessfully on revenge stories specially if its in a reverse tower format. The bad: The author has pacing issues wiriting the story, its like the author expects the revenge plot to carry the interest of the audience, sometimes he uses the flashback badly and does an overly long info dump which gets in the way of the fight's pacing, most characters including MC are unidimensional which is good for a short actionseries but not good if the author aims for a long series.

Honestly its bad and i think author tried to do an edgy start to captivate the audience but didnt know how to go from there, I'm on chapter 23 and dont recommend it, i reccomend to at least wait for it to reach 100 chapters that way either the editor managed to help the author or you can at least binge read the chapters which would help a bit with the pacing issues.
