Gu Changming, an overworked drone at a modern company, unexpectedly transmigrates to Shanghai in 1936 and becomes a Chinese police constable in the French Concession. Using a Reputation System, he deftly navigates the forces around him: the French Concession police, the Green Gang, the Central Bureau of Investigation and Statistics, the Military Bureau of Investigation and Statistics, the Chinese Communist Party's underground organization, Japan's Tokko and Kempeitai, and Wang Jingwei's puppet Headquarters 76. With multiple disguises and allies on every side, he continually builds his reputation and grows stronger, strikes at the Japanese invaders, and maneuvers among the Nationalists, Communists, and other factions. In the end, he becomes the “King of Shadows,” feared or courted by every power.
