@Blackthorn_lp   Yeah, in many cases, this is just the phases for the mortal realm, before ascension into the g** realms. And like Vishel pointed out, body refinement isn't always a phase, but then later around the foundation establishment, the MC starts hitting a bottleneck because he lacks a good body refining skill. There's also sometimes extra phases. Golden Core and Nascent Soul are considered big power-up phases, so there might be a crystalization phase after foundation establishment to prepare for Golden core, and a spirit refining phase to to prepare for Nascent soul phase.

@Kristers At this point, the system's version of going out is only ascending, as there is nothing in the human realms that can raise his level.
