"Indeed. The courses at magic school today can give the apprentices enough fundamental knowledge for them to become official sorcerers, but the arcana and magic knowledge needed for low-rank sorcerers to rise higher is now getting too enormous and complicated for them to learn and grasp on their own. That's the reason why the population of middle-rank sorcerers hasn't increased much in the past ten years, despite the sharp increase in senior-rank sorcerers." Brook nodded and agreed with Douglas' proposal.
It indicated that the new arcana theories and achievements did not lower the difficulties between the low rank and the middle rank, and the ratio of advancement was the same as before. However, for part of the distinguished low-rank sorcerers, their advancement was much easier after they picked up the new arcana theories, like Annick, Heidi and the other studies who had been taught by Lucien with cutting-edge knowledge.
