Modern office worker Li Da unexpectedly travels back to ancient times and awakens a resource-support system, embarking on a journey to establish himself in the countryside. Using supplies from his warehouse and modern knowledge, he overcomes survival challenges. Through hunting and selling grain, fruits, and vegetables, he gradually builds up his wealth and joins forces with Jiang Yu, Lin Wan, and Su Qing. As an outsider, Li Da gradually gathers people, builds houses, constructs city defenses, trains local militias, and eliminates bandits. Navigating relationships with local gentry and officials, he continually expands his land and accumulates strength, eventually establishing a secure settlement of his own and planning to expand into the wider world.
