In ancient times, there was once a legendary, powerful fiend known as the Asura Demon Venerable. This terrifying and mighty evil god descended upon the world through a series of dark rituals. After his arrival, the world became twisted and people's hearts turned dark. It seemed as though he controlled the entire world, until, twelve hundred years later, he transmigrated into the body of a descendant of the Azure Dragon. This descendant was named Xuanyuan Long. Xuanyuan Long had a master who descended from the Immortal Realm, the Fairy Miaoyin; a former first general under the Asura Demon Venerable, the Demoness Xiao Yue; and a quirky young girl. Would he become the Demon Venerable before whom all demons prostrate themselves, or an emperor shrouded in immortal aura?
