Shen Zhaoning, a daughter of a lowly family, avenged her father and forced open the coffin where the prince was buried secretly. She found a jade engraved with the prince's private seal between the knuckles of the corpse - the corpse of a clan member who was presumed to have died violently was actually a secret agent who had been silenced. She used autopsy skills to tear open the imperial book's covering cloth. Every corpse was a testimony, and every inch of corpse stain was evidence. When the emperor was furious and the powerful people surrounded and suppressed him, she used blood as ink and bones as pen to expose the murder chain to the public, and let the high-ranking prince kneel in front of her to listen to the corpse speak. To relieve one's anger and make a comeback is not to seek revenge, but to let the dead speak and let the truth overwhelm the imperial power.
