Chen Yan runs his family’s ancestral pawnshop in Binhai City. After unexpectedly acquiring a mysterious jade pendant, he transmigrates to the Great Liang dynasty and becomes the fourth-generation heir to the Qingfeng Pawnshop, a man who shares his name. With the Jade Pendant of Heavenly Surveillance, Chen Yan can travel between the two worlds. He also awakens the Qingfeng Mark on his palm, which lets him pawn memories, emotions, and even years of his life in exchange for whatever he needs.
The modern Special Affairs Bureau, the ancient Heavenly Surveillance Bureau, and the cross-world organization known as the Two Worlds Society are drawn into the fray one after another. Chen Yan discovers that his origins are a mystery and that a demon of Greed is sealed inside him. Forced to navigate among competing powers, he searches for a way forward amid crises involving awakened supernatural abilities, rifts in time and space, and the demon’s resurgence. From the imperial palace of Jinling to parallel worlds, from sealing the Seven Deadly Sins to fighting the Plan for the Convergence of All Worlds, Chen Yan gradually uncovers the ultimate secret behind the origin of pawning. It concerns the survival of every world, as well as his ability to protect those around him.
When the final choice comes, can Chen Yan find a third path of his own between divinity and humanity, sacrifice and protection? And can the one who pawns everything eventually buy back his own life?
