This is too childish. There are no proper fight scenes, even the realms are not properly made(author just gave the names but no explanation of how powerful it is), and the mc is addicted to killing.
Everyone including the mc are idiots who cannot think and are stunned by everything.
Only good thing is that the yapping of each character does not last more than 2 chapters.
It was ok in the beginning, but after mc avenges his father, the author stopped paying attention to the novel.
Overall trash mc, trash characters, trash plot, trash realms.
