Island Poseidon

The Battle of Songhu came to an end, and the whole of Shanghai fell. The concession became the only neutral buffer zone, forming an island pattern in which "the Japanese and puppets controlled the urban area, the concession was separated and balanced, and the forces of all parties were mixed." The Japanese army launched a strict material blockade and intelligence clearance, strictly prohibiting strategic materials from flowing into our front line. Penicillin, seamless steel pipes, precision machine tool accessories, and military code drawings are all special contraband. Once found, all personnel will be executed. In Shanghai at this time, there is no absolute security, only temporary checks and balances. The Japanese military's special high school led the intelligence investigation, and the gendarmerie controlled the force to suppress it. The Wang puppet government was a puppet vassal, and corruption was rampant. The Shanghai station of the military command was dormant behind enemy lines, with many factions and insiders, and self-interest was paramount. The underground red communication line operated secretly, and materials and intelligence were extremely scarce. It was the only lifeline of supply for frontline operations.
