So all of a sudden people in this world can use ki blasts like Dragonball. Great way to shit on techniques. Guy is carrying an iron fan. Why not just make him blow it away. The author got lazy.
@Drinkfist the power structure will be revealed as the story goes on. I don't remember a manga/manhwa being very detailed about the power system in the first ~40 chapters. Stuff gets revealed as time goes on, why call author lazy when you are just too lazy to read the whole story?
