Cultivation is Creation

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. *** Expectations: - MC's main cultivation method will be plant based and related to World Trees (chapter 24) - Weak to Strong MC - MC will eventually create his own lifeforms within his soul as well as beings that can cultivate - Main world is the first world (Azure Peak Sect) - MC will revisit worlds (extensive world building of multiple realms) - Light LitRPG aspects - Time loop elements - No harem
