The novel is set in the Guangdong-Hong Kong-Macao Greater Bay Area, with Guangzhou criminal policeman Zhang Zhenting as the main perspective. Through six thrilling criminal investigation stories based on real cases in recent years, it shows the life-and-death struggle between the police and high-tech criminal groups in the new era. The story not only focuses on the technical details of case investigation, but also deeply depicts the practical difficulties of judicial cooperation in the three places, the characters' struggle to make choices between love and law, and how those flesh and blood bodies in police uniforms find a balance between the justice of their family and their personal pain. The final revelation: In this land connected by rivers, the arrival of justice has never been smooth sailing. It requires countless people to walk forward in the gaps of the system and groping in the dark places of human nature with a lamp - and that lamp is the temperature of the bowl of soup that ordinary people can drink with peace of mind when they wake up in the morning.
