"We finished earlier than expected, and now I have no idea what to do next. Diving deeper might be riskier than I imagined since I don't know what lies beyond this region. Maybe I should just get you some more elements?" An idea hatched in his head about putting the Iron Monarch through madness attunement, but was that even possible after completing his elemental core?
"I know you're noble and all, and although I have no interest in such things, do you know a way to destroy someone's elemental core? I think I can help you get more elements, but we may need to destroy that garbage of yours first."
"No, you don't need to destroy a core to get more elements. I started with earth Qi, then added wind and water one after another. I didn't go for fire or ice since I couldn't handle getting burned or frozen while attuning my dantian to these elements. However, I believe I can do so now."
