Of course, his previous words were not entirely an excuse.
In certain respects, Jason really felt that way.
Facing the "mansion" before, Jason once again felt his own insignificance.
And with his core skill, [Protection Against Evil], lacking four points of Excitement of Feast, wanting to improve it was an indefinitely distant dream.
Similarly, another core skill [Prus-Griffon Body Forging Technique] was restricted by [Protection Against Evil] and could not be improved in the short term.
Therefore, Jason, wanting to increase his strength, could only turn his attention to other skills and secret techniques.
But with the condition of "does not consume Excitement of Feast," Jason almost had no choices.
He had already improved the rest of his skills and secret techniques to the point where they required Excitement of Feast to advance further.
So, it was only natural for him to think of self-training methods.
