Shen Qinghe, the legitimate daughter of the prime minister's estate, was framed by her stepsister and fiancé. She tore up her marriage contract, had her clan registry record struck, and was exiled to the northern wasteland. Refusing to kneel or cry, she reclaimed wasteland, fired celadon bowls to trade for grain, took in refugees, and built Qinghe Market. Xiao Chengji, the idle prince who had feigned paralysis for three years, secretly guarded her on all sides. Together, they saw through the schemes of poisonous grain, poisoned wells, grain storehouse arson, and murder, and instead set up an empty storehouse fire formation to wipe out the coming enemies completely. Peeling back layer after layer, the true culprit turned out to be her biological father, Prime Minister Shen Chongshan, who colluded with the enemy and betrayed the country. She flipped through account books, recited fake strategies, and scattered dirt in the golden palace, ultimately leading the traitorous villains into a prisoner's cart, presenting a farming strategy, and being enfeoffed as Lady Annong.
