Amber suddenly asked Cain, "Say, haven't we used all of our Inner World resources by now? Compared to the essence Marks, wanting to maintain this sea of essence is several times more troublesome. And I don't think we can just ignore it, right? Even with our deep foundation?"
Cain slowly shook his head. "No, we can't. Even from a logical perspective, sustaining our Inner World just makes sense. After all, we want to expand this dimension within us into a full-blown world. Taking time to sustain its vitality is akin to taking care of a garden. I'm sure even with our foundations, our Inner World can become decrepit if we ignored it for far too long."
With Cain's long yet logical explanation, Amber could only sigh with a wry smile.
Truthfully, there were many more cultivators who feel the same annoyance as Amber than Cain's logical perspective.
