In the discussion held in the Three Purities Doulu Palace, they clarified that Wukong had indeed been sent by Laojun into the Bagua World created by Fuxi.
This Bagua World was extremely mystical, and if one entered before their destiny had matured, they would get lost within it. Even a saint would have to exert great effort to escape! Tao Yao, however, seemed to possess some secret technique that protected her body, allowing her to maintain a sliver of clarity within the Bagua World. Were it not for her, Wukong would have likely lost his way in the Bagua World long ago, unable to awaken until the cosmic cataclysm, forever bewildered within.
