The main character is Ye Jun, a modern female forensic doctor. While exploring an ancient mirror, Ye Jun was involved in the "mirror world" by a mysterious force. She traveled through many eras of modern Chinese history and woke up in the bodies of women such as Qin Yuyao, Lin Siman, Wang Xinran, Chen Zhiqing, Shen Lanruo, etc. In each volume, she needs to rely on the host's social background and personal expertise, and work with her real-life connections to solve unsolved cases - some are sophisticated murder cases, some are weird and supernatural, and some involve family, country, family ties and social currents. After each mystery was solved, she pieced together the mystery of her own time travel piece by piece, and gradually got closer to a female secret organization that spans time and space and the mastermind behind it - the mysterious female figure. In the end, she needs to face the biggest mystery in the mirror: self, fetters, and the entanglement and redemption of fate.
