The core of traditional espionage warfare is passwords and assassinations, but this game moves the battlefield to "logistics and materials". What the protagonist Jiang Heming possesses is not force or the art of disguise, but an almost pathological talent for "material flow deduction". He does not need spies and informants. He only needs the Japanese and puppet army's purchase orders, transportation schedules, and factory production capacity reports to deduce the time and scale of the enemy's next large-scale attack. His greatest weapon is not a gun, but an abacus.
