Li Wei, an impoverished scholar, transmigrates to the Great Yan Kingdom and activates the Strategy Simulation System. He earns his licentiate qualification by cleverly exposing a local gentry family's grain embezzlement, brews vinegar to make his first fortune, and befriends Zhao Meng, the son of a military family. Later, he sees the threat posed by bandits and helps Magistrate Zhang Huaimin ambush and defeat them, earning a recommendation to study at the prefectural academy. There, he secretly investigates and exposes Assistant Lecturer Zhou Wenyuan's collusion with bandits to sell illicit salt, further securing his position. With his wits and careful planning, Li Wei rises step by step from desperate circumstances.
