there is the pupil's arc, then there is the blacksmith association arc (again the same kind of villains that envy MC success and demand his secrets of production), then there is the suposed to be "climax" of this series that is the Elisa+dad (prime minister) downfall, next thing that happened was the Helan Territory downfall (it was apocalipse/oblivion like), then it begins the current arc but author gets boring and doesn't know what to write, his chapters become boring and same jokes are repeated again and again as if all of his plans had ended, it became like Bleach after Aizen. The novel now looks like that author is trying to squeeze every penny that he can with some fillers, until he gets some creativity to create another good arc or another novel
