Lin Shizhou activates the System's “Supply Chain Simulation” function, turning a map of the area around Shanghai into a dynamic 3D network of secondary waterways, country lanes, and secret passages. Facing a 99.8% chance of interception by the Japanese army, he combines the Su and Shen families' connections and sets a goal of transporting 500 tons of supplies within 72 hours. The System generates three plans using concealed waterways, relay teams, and gaps created by bribing puppet troops. Lin Shizhou orders the plans combined into an optimal hybrid route that breaks shipments into small loads and avoids the blockades. He then urgently summons Su Huaiyuan and contacts Ye Manqing to recruit large numbers of porters familiar with the waterways and back roads, launching a counterattack through a “capillary” transport network.
