The male patron, Gu Changye, is an inconspicuous fortune teller in the capital. He relies on his ancestral "divine mirror" to see past fragments related to objects or people, and makes a living. In an accident, he was involved in a "ghost bride" murder case and met Shen Qingxian, the owner of Princess Jingan who was secretly investigating the case. Gu Changye relied on the ability of the Tianji Mirror to provide clues that no one could find, which attracted Shen Qingxian's attention.
The two began to test and use each other, and formed a temporary partner to solve the case. From the "Painted Actor Case" to the "Headless General Case" to the "Tribute Stolen Case", the cases they solved became more and more bizarre, and the court forces involved became more and more powerful. In the process, Gu Changye discovered that behind all the cases, there was a mysterious organization called "Wuxiangren", which seemed to be inextricably linked to his long-lost master and the origin of the Tianji Mirror.
At the same time, his relationship with Shen Qingxian also changed from cooperation to trust, to secret love. But as the princess, Shen Qingxian also bears family secrets and royal mission, and her true purpose is also confusing. When the two finally touched the core of "No Encounter", they were horrified to discover that the goal of this organization was not simply the power of the court, but related to the fate of the country and a royal murder that had been covered up for hundreds of years. Gu Changye's identity, Shen Qingxian's mission, the truth about the Tianji Mirror, and the fate of the entire Dajing Dynasty will all be revealed in the final showdown.
