Damn so she has multiple "souls" I guess and the crazy one is still around.
Think it's referencing the 3? souls of humans in whatever asian lore (chinese I think). It's something like human soul, earth soul, heaven soul or something? And her cultivation prb required her to shed at least one of her souls to reach a higher realm or something.
What I'm saying it, everyone has multiple souls, shes just a bitch but not because of her souls.
