Ling Xuan, the ancient order divine lord who has slumbered for ten thousand years, awakens. The divine realm seal has been intentionally destroyed, and fifty Shan Hai Jing exotic beasts have escaped into the 2022 modern society. To protect the mortal world and stabilize the order of the two realms, Ling Xuan descends to earth, incarnating as a freshman at Jiangcheng University, and sets out to recapture the escaped exotic beasts. He befriends his classmate Su Wan, who possesses a dormant ancient bloodline and can perceive demonic aura, making her Ling Xuan's most important bond in the mortal world. Ling Xuan travels around capturing exotic beasts such as ghouls and nine-tailed foxes, and can summon contracted exotic beasts to fight alongside him. During the chase, Ling Xuan discovers that the escape of the exotic beasts is merely a trap; the mastermind attempts to exhaust his power and seize the order divine core to control both realms.
