Records Division

The Dajing Dynasty had two divisions. The Archives Division masters the art of observing records and infers past events from old case files and remnants of the past; the Memory Division possesses the Memory Cleansing Technique, which can erase people's memories and seal secrets that they do not want to see in the world. Shen Yan, the youngest head of the Archives Department, is good at solving puzzles with broken documents. An old case has been reopened. The case of the Marquis of Jing'an Mansion that caused a sensation in the government and the public 18 years ago has been reopened. The files record that all the members of the family were killed and no one survived. But in the residual illusion left at the crime scene, Shen Yan heard several times a child who had been erased from all files and everyone's memory, calling out his long-forgotten nickname. Did that child really exist? As a series of mysterious cases broke out one after another, the two companies performed their respective duties on the surface, but secretly cracks gradually emerged. The truth is buried under layers of tampered files, and good and evil are no longer clear-cut. Every page of the case file he opened could shake the foundation of the entire court.
