The prison officer was killed in the interrogation room, Huang Pusheng's identity was grafted onto his memory, and the six languages became a sharp blade in intelligence warfare. Professor Bai Ge from the underground party of the Chinese Communist Party secretly flirts with him, and the Green Gang boss hides his red genes. On the surface, he looks like the straight suit of a major from the Fuxing Society, but inside he hides the sharpness of the "hidden blade" of the Chinese Communist Party. Yama, who is in awe of the special high school, plays tricks among the three forces and rewrites history! And when he pulls the trigger, his target is never the chest of the enemy, but the darkness that deserves to be crushed in that precarious era.
