Shanghai fell and the concession became an "isolated island". Xiao Fei, a young man from a wealthy family, has just returned from studying in Japan. On the surface, he appears to be a handsome young man, but secretly he is a military agent. His fluent Japanese allowed him to easily break into the Japanese spy circle and work with the female spy Ozawa Kawashima to obtain intelligence for the Chinese.
But Xiao Fei knew in his heart that there was already corruption within the military command. Until he met Li Wan, a progressive young woman, a Fudan college student who was pushed down by Agent 76 during a parade on the pier, but still shouted "Give me back my country". Li Wan allowed him to see his true faith and also led him to embark on another path - becoming an underground member of the Communist Party.
From then on, Xiao Fei began the most dangerous game: during the day, he was the "own man" of the Japanese secret service, and at night, he was the "egret" of the underground party; while dealing with the temptation and temptation of Ozawa Kawashima, he also protected his relationship with Li Wan. Every time you deliver information may be your last, and every time you meet your loved one it may be an eternity.
This is a lurking dance on the edge of a knife. The alleys of Shanghai, the bells on the Bund, and the revolving doors of the Peace Hotel are all his battlefields. Ozawa Kawashima sets traps by hook or by crook, but Xiao Fei is always able to avert danger by relying on his background in Japan and extraordinary wisdom. When everyone thought he was a traitor, he was fighting for his true motherland.
No superpowers, no cheating, just real humanity and wisdom. Xiao Fei will make mistakes, get injured, and hesitate, but never give up. He uses the curvature of the Suzhou River to convey information, uses tea ceremony etiquette to hide secrets, and uses the rotation of the Ferris wheel to encode information - this is a real spy war, without so many "magic operations", but real chapters everywhere.
