Shanghai Longitude and Latitude: 1932

In Shanghai in 1932, Shen Yanqiu, the heir to the Shen family's shipping industry, awakened to the "resource deduction" system. He secretly planned in the cracks between the three forces of the Japanese army, the Youth Gang, and the government. Using the shipping network as his blood vessel, he built an underground pharmaceutical factory and weaved a dark network between the concession and the base area. When the war breaks out, this dark web will change the lives of millions of people.
