Beyond the Nine Heavens and Ten Lands, where the Primordial Ancient Realm bordered the Burial Domain and the Foreign Domain.
For several eras, this place had been the main battlefield where the forces of the Nine Heavens and Ten Lands clashed with the armies of the Foreign Domain-a land of utter annihilation and desolation.
He Mu took a single step out of Immeasurable Heaven and appeared here.
He paid no attention to the majestic Imperial Pass behind him. Though imposing and no mere hollow showpiece, its defenses were primarily meaningful within the Human Dao. In its current, damaged state, the Imperial Pass posed little threat even to stronger True Immortals and Undying beings.
