On a stormy night, delivery rider Chen Mo receives a bizarre order and is unexpectedly drawn into the mystery of a bronze door that connects the past and present. No bigger than a palm, the door conceals secrets spanning thousands of years and is bound to the hidden “Gatekeeper” bloodline within him. Whenever it opens, he sees fragments of figures in ancient clothing in his dreams. In the real world, graffiti on an unfinished building, mysterious text messages, and a steady stream of miniature bronze doors all push him toward a life-or-death struggle.
As his investigation deepens, Chen Mo discovers that beyond the bronze door lies a “Mirror Dynasty” on the brink of collapse, whose people feed on modern humans’ obsessions. His task is to find a way to seal the door before it opens completely. Along the way, he joins forces with Su Qingyuan, a history student who can read ancient texts and seems aloof but carries a family mission, and Lao Jiu, a mysterious antique shop owner who seems mercenary but always lends a hand at crucial moments. As the three seek the truth, they must fight the Mirror Dynasty’s “Shadow Servants” and uncover the bloody, heartbreaking history of Chen Mo’s family, which has guarded the bronze door for generations...
