"You've prepared more than ten Concepts? That sounds so ridiculously exaggerated. Just how many Concepts have you actually prepared?"
"Ha, this is the most foundational secret of any Myth- or SemiGod-rank individual. Did you really think that I would tell you…? Fine, I admit it, even I don't know the exact number."
Since my two female companions kept looking at me with expressions of "I can see through you" and "Just keep making stuff up", I was unable to handle it and told them the truth.
"For everyone else, the most critical step is to find their personal Concept that they can use to power themselves up. However, I've already accumulated more than ten Concepts I can use due to my personal experience over my previous four lives. My troubles are different from everyone else. I don't know which of my personal Concepts are worthy of being used, nor do I know which of my Concepts can successfully be powered up. Finally, I have no idea what limit my physical body can handle."
