In a year of great famine, Gu Changning is reborn and awakens golden eyes that can discern the fortune of grain. She tears up the unscrupulous grain merchant Wang Defa's contract to exchange grain for her family's land deeds and turns discarded, moldy wheat bran into hunger-quelling divine cakes, opening her own workshop. When Wang Defa hoards raw materials to crush her business, she finds a way out by sourcing kudzu roots and acorns, secures a major government disaster-relief order, acquires a grain shop, and later receives an imperial decree to travel to the northern frontier to oversee the production of military provisions.
