The heroine, Shen Yanzhao, was originally the daughter of a criminal official. She entered the palace incognitoly as a showgirl. She was deposed as a coarse envoy of the Huanyi Bureau due to her "smiling face" in the first election. When she was unpacking and washing the late emperor's old robe, she found half of the bloody imperial edict fragments in the interlayer. The four words "after deposing the throne and setting up the crown prince" were gouged out with a sharp weapon, and the positions of the three imperial seals were seriously inconsistent with the records in the "Dasheng Law Seal System"; from this, we can investigate the rotation of the imperial army on the night of the death of the late emperor, the pulse of the Imperial Medical Department, and the weaving records of the Shangfu Bureau Twelve layers of contradictory evidence, including the records, revealed a shocking closed loop in which the empress, the queen mother, and the director of ceremonies conspired to forge the edict, poison the emperor, frame the emperor, and tamper with the genealogy. There was no supernatural intervention in the whole process. All breakthroughs depended on the heroine's ultimate use of real ancient knowledge such as ancient writing style, court rituals, medicinal material compatibility, fabric age, and seal wear. Every step of reasoning can be verified, and every reversal is backed up by physical evidence and human testimony.
