Shen Qingci, the tomb keeper of Zhongnan Mountain, was targeted by the palace forces because of the "key to the ancient tomb" left by her adoptive father, and was forced to enter the palace as a show girl. Using ancient tomb mechanics, autopsy skills and her familiarity with ancient secrets, she successively solved palace murder cases, concubine frame-ups, and emperor's trials, and gradually uncovered the deep connection between the late emperor's tomb and the current court - Emperor Xiao Jingheng's throne actually relied on the "Secret Records of Dragon Qi" in the ancient tomb, and her life experience involved the secret past of the late emperor and the family that guards the tomb. The heroine goes from being an "ominous tomb keeper" to beating the concubines in the face, conquering the emperor, and finally becomes the queen who masters the secrets of the palace and the ancient tomb, breaking the shackles of fate.
