Lin Yu, a young man from the modern era, transmigrates to Republican-era Shanghai and awakens a Spy Warfare System, only to stumble into the Military Statistics Bureau and become trapped in a deadly scheme. Drawing on his modern thinking and the System’s abilities, he navigates the Japanese, the Wang Jingwei regime, and the Allies, and accidentally uncovers the shocking plot of a mysterious Japanese organization called “Sakura.” When his comrades are killed and trust collapses, Lin Yu ventures alone into the enemy’s lair, where he discovers that Sakura’s leader is a strange young woman who commands supernatural powers. To stop “The Coming of the Other Shore,” a catastrophe capable of destroying everything, he joins forces with the underground resistance and makes use of American resources, fighting back against poison gas warfare, economic strangulation, and the erosion of consciousness. This is a desperate battle that spans dimensions. As an eerie blue pillar of light rises beside the Huangpu River, Lin Yu’s bullet must pierce the barrier between two worlds.
