Su Wan crosses over to become the daughter of a criminal official about to be exiled, facing hunger, cold, and a life as cheap as grass. The Homecoming System is activated: only by sacrificing her life for the people in martyrdom can she return to modern times. Just as a torrential rain is about to fall and the river dyke is on the verge of breaching, all the officials in the whole city dare not take on the hot potato. Accepting it means certain death, with raging floods, accountability for martyrdom, and no bones left. Su Wan's eyes suddenly shine brightly—a heaven-sent opportunity to return home! All the court officials sneer at her as a mere weak woman seeking her own destruction.
