I never used to worry about how to gain more power, but at this moment, it seems I've finally confronted the toughest challenge in the demon hunter's training, and it starts right at the highest difficulty level.
In my situation, if I purely wanted to gain power and did not hesitate to kill myself with a grand forsaking heart to hatch a new self, the most efficient method would be to completely give up on adventure.
Reflexively, I felt repulsed by this thought. Simultaneously, out of curiosity, I still speculated on how exactly I might achieve this so-called abandonment of adventure.
Firstly, if I just tell those around me that I won't continue the adventures anymore and lock myself up inside the house doing nothing, this wouldn't count as completely giving up on adventure. It could only be called pausing the adventure because I might have a change of heart at some point and set off on an adventure again. In spirit, there's still a significant fallback option.
