Two male protagonists: Shen Yan, who appears to be a gentle and restrained restorer of ancient books, but is actually a secret leader of cultural relics investigators who hides in the world. He is good at observing micro-expressions and close combat; Lu Zheng, to the outside world, is a bold and flamboyant CEO of a multinational auction house, but behind the scenes, he is a tracer of cultural relics who travels in both black and white, and is proficient in layout and information warfare. The two people's positions seem to be opposite, but in fact they have the same goal - to recover Chinese national treasures lost overseas and to eliminate the black network of cultural relic smuggling. They are each other's strongest rivals and only confidants.
