Su Qingyuan, a top modern forensic doctor, was scratched by the gilded token hidden in the corpse while dissecting the unknown female corpse unearthed from the "Tomb of the God of War in the Late Ming Dynasty". She opened her eyes and traveled through time to become Su Qingyuan, the legitimate daughter of the Marquis of the Dajing Dynasty who was accused of "collaboration and treason" with the same name as the unknown female corpse. The original owner was poisoned and killed just after he was thrown into the sky prison. Before his death, he was holding half of the black iron token of the same style as the male protagonist.
