Late at night in Yanbei City, the light from the Red Dragon Society's interrogation room pierced the darkness. Staring at the man in the interrogation chair, he saw the man who had once been his mentor, now a traitor to the organization. Outside the window, the stone tablets in the Martyrs' Park shone coldly in the moonlight, like countless eyes observing this battle of betrayal and redemption. As the Red Dragon Society's youngest agent, Qin Lang, codenamed "009," embarked on a mission from the hail of bullets in New York to a life-or-death escape in Goryeo. Every step he took was a dangerous one—he had to assassinate the traitor while uncovering the mole hiding in the shadows. His only ally was Lin Xue, who shared the danger with him.
