I am having some trouble understanding the ranks here.
As I understand it people start off cultivating their bodies, gaining energy and seeking to grasp Heavenly Energy.
They then take that energy and feed it into their Blood Wheel, which processes it like a computer CPU.
Then the energy flows either out into spells, or in a method depending on cultivation technique into the Fate Palace, reinforcing it and eventually opening the doors and bringing them into the Yun Psysique realm.
Am I right so far? (Not entirely certain).
Now they train various methods to strength all three parts, none of which are irrelevant, but all with the intent of continuing to empower to the Fate Palace which is the seat of the true cultivation.
Now the first palace that gets opened is the one people are born with, their very soul, containing everything that makes a person a person. They can shape it a bit, add things (like the Kun Peng in the MCs) through cultivation but in general it stays largely the same.
However... then they get 'vice palaces'? What are these? Are they supposed to represent the meridians? Alternate souls? Multiple personalities?
And how does one go from multiple palaces to the next step, do you need X palaces to form the foundation for a Core?
