Who Let This Immortal Cultivate Unholy Ways!

Immortal Ancestor Ye Canglan was severely injured by righteous master Liu Qingtian three hundred years ago and fell into a deep slumber. Upon awakening, he met several cultivators by chance and began repairing his damaged cultivation. To find the Heaven-Refilling Pill needed to heal his wounds, he infiltrated the Illusion Palace, where he unexpectedly obtained the Celestial-Earth Pearl, which holds the secrets of ascension. Liu Qingtian, his enemy, sent subordinates to hunt Ye Canglan everywhere, sparking a complete conflict. After killing his old foe, Ye Canglan discovers that Liu Qingtian has already switched sides to the Demon Clan, which is planning to invade the human race to plunder cultivation resources. Facing the Demon Clan's massive assault, Ye Canglan breaks through his limitations and enters the ascension realm. With his overwhelming power, he defeats the Demon Emperor, clears the invasion crisis, and ultimately ascends to the supreme position of the human race.
