Xie Yunqin is the legitimate son of a down-and-out prince, and he secretly established an intelligence network to investigate the truth about the family's downfall; the heroine is the daughter of a merchant, who runs a silk and satin shop on the surface, but in fact stirs up the storm with "information trading". The two met because of a counterfeit banknote case, and the heroine saw through his disguise: "Why don't you exchange secrets for the information Mr. Xie wants?" They formed an alliance for their own purposes, and during the investigation, they discovered that the murder of each other's family was actually at the hands of the same force. When the final showdown came, Xie Yunqin blocked the arrow for the heroine and fell off the cliff. She jumped without hesitation: "You and I are allies, and we have to die in the same situation!" What awaits them at the bottom of the cliff is a greater conspiracy and hope.
