Cultivation is Creation

Ke Yin has a problem. Well, several problems. First, he's actually Kane from Earth. Second, he's stuck in a cultivation world where people don't just split mountains with a sword strike, they build entire universes inside their souls (and no, it's not a meditation metaphor). Third, he's got a system with a snarky spiritual assistant that lets him possess the recently deceased across dimensions. And finally, the elders at the Azure Peak Sect are asking why his soul realm contains both demonic cultivation and holy arts? Must be a natural talent.
