Ji Yuan, a low-level courier, received a strange delivery task - the recipient was Chen Jiu, a Taoist priest who died three years ago, and the delivery location was Qingyun Temple, which had been abandoned for ten years. When he uncovered the black cloth with his own hands, what awaited him was a dried corpse and a life-and-death chase. Accidentally awakening the "Echoing Eye", he can see fragments of other people's memories, but he is also involved in a century-old game between two mysterious organizations. On one side is the cruel and cold-blooded "Owl" organization that conducts human experiments, and its leader Shen Xiao vows to take his eyes; on the other side is the "Qinghetang" who claims to be righteous, but tells him "don't trust people in white shoes." The truth about the death of his parents, the secret of the wooden box seal, the origin of special abilities... Ji Yuan gradually discovered during his escape that he was not a prey, but the key to unlocking all mysteries. When a call from the deceased rings, and when a white shadow appears on a rainy night, he must make a choice - continue to escape, or uncover this layer of darkness and seek justice for his parents and himself?
