Tang Yuqing, a criminal investigation graduate student, was originally a beloved only daughter, but accidentally traveled to the prosperous Tang Dynasty in a museum and was involved in a strange wedding murder case.
Being regarded as a murderer, she formed an indissoluble bond with the Ninth Prince Li Jinyu who was carrying a secret. She relied on modern criminal investigation techniques to repeatedly solve strange cases, and he used his peerless martial arts to save her from danger many times. From the bride poisoning case to the border rebellion case, from the mystery of the Netherworld Pavilion to the crisis of time and space, the two work together to uncover the layers of mystery.
By chance, she discovered that the jade pendant she carried could open a space-time channel. Modern evidence collection technology meets ancient martial arts, and criminal investigation logic collides with court tactics. The local brought the prince and princess of the Tang Dynasty back to modern times. The handsome man in ancient costume and his best friend in the prosperous Tang Dynasty triggered a series of ridiculous stories in the modern city.
However, when the rift in space and time quietly widens, the balance of the two worlds is in jeopardy. She must make the final choice - return to the stable life of modern times, or protect the prosperous Tang Dynasty that she personally changed?
