The story is interesting, but there are a lot of things that bother me. I love fanfic, and don't expect too much or you'll be disappointed.

the story is exciting, but I'm annoyed and tired of the MC's attitude, which plans likes to stop midway in his stance, too much burden, limits himself, and he puts aside the thought that he is just a pawn of the system, as he injects into the npc every data in the world, in function Injection, sometimes I'm very annoyed, MC has promising development but he's limited, always taking it for granted because it's already master
