Three years ago, the young fighter Yun Qingyan vanished from the mortal realm, only to be pulled into the fairy domain for three millennia. Harnessing his skill, he rose to become Yun Emperor, one of the ten eminent fairy sovereigns. Yet wearied by court intrigue and longing for kin, he resolved to return to the human world at any cost. When he reappeared among humans, his parents and sister had inexplicably disappeared; an incident during the transition stripped him of his magical blade and reduced his cultivation to near zero. Opportunistic powers seized the moment, hunting him relentlessly. The fairy emperor faced public scorn, and his family lay in peril. Drawing upon his imperial prowess, Yun Qingyan forged pills and devised formations, studied, and vanquished foes. He set out on a quest to restore his family, locate relatives, and heal the mortal world. His journey takes him across forests, ruins, and cities where he confronts cultivators, officials and beasts. He must decipher scrolls to regain power and uncover truths about lineage.
