Hidden Dragon in the Abyss!

In 1937, the Battle of Songhu broke out. At a time when the life and death of the Chinese nation was at stake, a silent war unfolded in secret. Chen Mohan, codenamed "Qianlong", is the leader of the military command Shanghai station operations team and his apparent identity is a reporter for "Shen Shen". This young man from the Whampoa Military Academy went deep behind enemy lines to engage in a desperate battle with the Japanese secret service, established an intelligence network in a foreign field ten miles away, and contributed to the cause of the Anti-Japanese War. Fate led him to meet Lin Ruoxue, who appeared to be a nurse at Tongren Hospital, but was actually "Bai Mei", an underground member of the Chinese Communist Party. The two went from testing to fighting side by side, and the Kuomintang and the Communist Party cooperated to defend against foreign enemies. However, the enemies are equally powerful: Japanese spy agency Major Fujita Yasuo is cunning and cruel, Qian Zhiyuan within the military command has doubts about his loyalty, and Wang Puppet senior official Li Mingde appears to be resisting Japan but is actually a spy. As the war situation developed, the Japanese military conspiracy code-named "Yangtze River Plan" emerged - an attempt to establish a complete intelligence sabotage network in the Yangtze River Basin, involving the destruction of port bridges, the infiltration of high-level national military officials, and the acquisition of Chongqing government secrets. From the bloody storms in Shanghai to the years in the mountain city of Chongqing, from the tragic struggle in Nanjing to the secret war on the Yangtze River, Chen Mohan and his comrades danced on the tip of the knife, deciphering codes, going deep into tiger dens, rescuing comrades, and passing on intelligence, saving danger time and time again. In this invisible war, everyone faces difficult choices: loyalty and betrayal, personal emotions and national justice, survival and sacrifice. Finally, on the eve of the victory of the Anti-Japanese War, the good and evil sides ushered in the final decisive battle. Chen Mohan must prevent the implementation of the "Yangtze River Plan" and clear the way for the victory of the Anti-Japanese War.
