Return Boat in the Dark Night

After the Wuhan Battle in 1939, Shanghai became an isolated island, Nanjing became the puppet capital, and Chongqing became the wartime capital. Four forces are strangled: the Japanese Special High School, Wang Puppet No. 76, The Shanghai District of Military Reunion, and the Shanghai Underground Intelligence Group of the Communist Party of China. The whole book focuses on intelligence warfare, cipher warfare, assassination warfare, latent warfare, and anti-corruption warfare.
