In 1941, the two occupied cities of Shanghai and Nanjing became the core battlefields in the game between ourselves and the enemy. The "No. 76" Secret service headquarters of the Wang Puppet Regime (No. 76 Jisi Feier Road) colluded with the Japanese agency to launch a frenzied crackdown on the underground party.
