A story about once the darling of the world now, a fallen god, and his last believer who rules the ghosts and terrifies the heavens as they uncover the dark secrets of the gods and the entire Heavenly Realm.

Eight hundred years ago, Xie Lian was the Crown Prince of the Xianle kingdom, beloved by the citizens. He ascended to the Heavens at a young age of 17; however, due to unfortunate circumstances, he was quickly banished back to the mortal realm. Years later, he ascends again-only to be banished again a few minutes after his ascension. Now, eight hundred years later, Xie Lian ascends to the Heavens for the third time as the laughingstock among all three realms. To accumulate merits in order to make compensation, he travels to the mortal realm and eliminates evil. In the mortal realm, he is accompanied by two little immortal officers from the Heavens, and on his first task, he meets a mysterious ghost king named Hua Cheng who rules the ghost world and terrifies the Heavenly Officials. Yet unknown to Xie Lian, Hua Cheng has been paying attention to him for a very, very long time.
