Stargazer Shen Yanqing used astrological deductions to secretly investigate the unjust case of his father and brother, and gradually exposed the triple forgery behind the imperial power: the handwriting of the imperial edict, the autopsy testimonial, and the records of star officials. Each time the forgery was uncovered, a key witness died suddenly and mysteriously, and the same old-fashioned copper bell soaked in blood appeared at all death scenes - it was the soul-killing bell that she had tied to the four corners of her dead mother's coffin when she was a child. The truth points to a secret ceremony of "stargazing on behalf of the emperor" that spanned fifteen years: the emperor died suddenly on the eve of his ascension to the throne, and the person who is now in charge of the throne is a substitute. He is also the person who personally tied the first bell for him when she was a teenager.
