King-Suppressing Mound lay within Immeasurable Heaven, one of the Nine Heavens, and was one of the many Life Forbidden Zones in the Nine Heavens and Ten Lands.
Of course, unlike Forbidden Zones such as Immortal-Falling Ridge, this place was not a set of Daoist Grounds established by an Immortal Dao figure of old. It was where He Mu's Primordial Spirit Incarnation, the Lord of Immeasurable Heaven of the Immortal Ancient Era, had fallen.
