This is a conspiracy novel in ancient Chinese. It tells the story of Xie Zhaoyi, who traveled through time and became the "Crazy Queen". After tearing up the "Book of Filial Piety" given by the Queen Mother in the cold palace, she gradually uncovered the truth about the palace conspiracy. Using her apparent "madness" as a cover, she teamed up with the maid Lin Yanqiu, who had her father's hatred, to accurately poke at the emperor's hidden pain - Xiao Chengyan's constant headaches were not a disease, but the fear of hatred that he had suppressed for thirty years. She sealed his throat with a silver needle, forcing him to confront the Queen Mother's transgression, and even hinted that the jade pendant on his sleeve hid his mother-killing intention. The three people turned from enemies to allies, and started a life-and-death game about "filial piety is a shackle" around a tampered "Book of Filial Piety", poisons that were blindly exchanged, and half a jade pendant symbolizing lust for power. The novel uses the images of ashes in the cold palace, bitter almonds in the pharmacy, and cracked jade on the emperor's pillow to describe the human nature and rebellion crushed under the palace rules.
