Gu Yun Zhao, the legitimate eldest daughter of the Duke of Zhenguo's household, was framed by her stepmother three years ago as someone who brought calamity upon her mother and younger brother. Her cruel father then expelled her from the capital with a single written decree. But she survived and refused to surrender to fate. At the border, she studied medicine under a master and secretly built a commercial empire. Three years later, armed with medical skills capable of bringing the dying back to life, she returns to the capital by imperial decree at the Empress Dowager's invitation. She has no second chance at life or miraculous cheat abilities—only genuine talent. She establishes her reputation by saving lives with her needles, reclaims her dowry through commercial warfare, and turns the tables on old accusations with her sharp tongue. Those who once trampled her into the mud will be brought to their knees one by one. The former adversary who broke off their engagement now kneels and begs to marry her again. From marriage before love to true affection, the couple joins forces to set the entire household straight and uncover the truth behind her mother's death and the military payroll scandal at the border. Packed with satisfying reversals and relentless face-slapping.
