From Airship:
Born the crown prince of a prosperous kingdom, Xie Lian was renowned for his beauty, strength, and purity. His years of dedication and noble deeds allowed him to ascend to godhood. But those who rise, can also fall and fall he does, cast from the Heavens again and again and banished to the mortal realm.
Eight hundred years after his mortal life, Xie Lian has ascended to godhood for the third time. Now only a lowly scrap collector, he is dispatched to wander the earthly realm to take on tasks appointed by the heavens to pay back debts and maintain his divinity. Aided by old friends and foes alike, and graced with the company of a mysterious young man with whom he feels an instant connection, Xie Lian must confront the horrors of his past in order to dispel the curse of his present.
