Run Yu, the first and eldest son of the Celestial Realm and the Celestial Emperor, and the Dragon Prince of Dongting Lake, is a water-element immortal. He is the God of Night and is known for his calm disposition. He always keeps an immortal deer by his side. He is forced to live a quiet and solitary life in the Celestial Realm, as the Celestial Empress suspects that Run Yu will one day become Emperor.

And he meets Lydia, a Fairy Princess.
