Modern battlefield medic Jiang Wan carries her medical space and transmigrates into an evil female supporting character in an ancient Prince of War's mansion. On her wedding day, the mansion is framed and raided, and she saves her heavily injured husband, Song Jiuyuan, successively emptying the imperial household and enemies' storehouses to hoard supplies, activating a cultivable and upgradable hoarding system. On the exile journey, she relies on her medical skills and formidable martial arts to protect Song family close kin, counterattacking petty clan members, subduing official runners and befriending the good along the way, exposing the imperial prince's treasonous plot, and hoarding enough supplies to safely rush toward the barren lands.
