"Cognition is a prison, sobriety is madness" The world is a false reality woven by the dreams of a sleeping old ruler (tentatively called "Mother of All Origins, Shablanko"). The system of cultivating immortals is the dream's self-sustaining "immune system", used to screen and assimilate those individuals who can perceive "reality". Su Youning's existence is "an error code in a dream", and her time travel breaks the boundary between dreams and reality.
