Back in the mid-ancient primordial era, after Lady Houtu sensed the Heavenly Dao's compassion for all life and transformed into reincarnation, the Witch Clan's Twelve Heavenly Gods Demon Array was never seen in the world again.
The Witch Clan still exists, so the array, claimed to be the first war formation in the myriad realms of the heavens, certainly would not be lost. When the Battle of Witches and Demons broke out, the Ancestral Witches did not use the Twelve Heavenly Gods Demon Array mainly because, after losing Lady Houtu, the other Great Witches, whether in strength or the richness of their bloodline, were incomparable to the Ancestral Witches. Hastily allowing the Great Witches to form the array together with the Ancestral Witches would create weaknesses. Heavenly Emperor Jun with the River Map and Luo Book in hand would surely deduce and exploit any vulnerability. A small mistake could easily lead to the array's collapse.
