Mage in the World of Cultivation

A magician roams across the lands of the Aether unhindered, slaughtered unstopped, and lived undyingly. Neither Good nor Bad for he destroys all! However the higher one is, not only is the fall harder, but the peak itself is narrower. He dies in blazing glory, facing against an army of both Gods and Devils together. But for someone of his stature, could he really die? He soon wakes up and finds himself staring at a baby, only to realize it's a mirror. However, that is the least of his worries, as where he is no longer a land where magic and spells ruled. Where he is now is the continent of Adia, the land of immortal cultivation!
