General Experience Points were reserved for moments like this. Kael knew well that he was not the teenage genius people imagined. Even with the dual assistance of Dark Knowledge and the prodigious memory entry, it was still difficult to catch up with those top-tier geniuses in the eureka moments of true research fields.
However, using General Experience Points to overcome bottlenecks and ensure the smooth progress of some research projects was the most reasonable use of these points.
Throwing resources at the problem? Even if Kael sped up his Dungeon conquests by ten to twenty times and gained a larger amount of General Experience Points, it still wouldn't fill that massive gap.
Progression stages relied on himself, while breaking through bottlenecks depended on the "insights" provided by General Experience Points. This was the development path most suited for Kael.
