The Son of Heaven Method, grasping the heavenly moment, and the subsequent Supreme Celestial True Solution are all related to the Heavenly Mandate. When combined with the cultivation methods of the Bright Mirror Sect, they evolved into mirror avatars with different fiendish qi cores, centered around An Jing.
