Interpol Lu Jingshen worked undercover in a drug den for three years. On the day his identity was revealed, his biological father put a gun to his head: "Son, either kill me or die." After he pulled the trigger, he learned that his father was the police's top undercover agent. From then on, he carried the name of patricide and became the most brutal "prince" in the underground world. When the police issued a wanted order and underworld pursuit orders spread, Lu Jingshen discovered that he had long been the outcast in a shocking chess game. He wants to live, to clear his father's name, and to drag all those who are hiding in the dark to manipulate everything into hell.
