Long Night of Peace

An arrest operation many years ago resulted in Lin Yongge's unfortunate death. Ten years later, his son Lin He restarted the police call, and his biggest wish was to personally arrest the criminal. By mistake, a criminal case investigated by Lin He intersected with a case secretly investigated by the National Security Investigation Division, and he was transferred to the National Security Bureau, getting closer to the target person in his mind. While uncovering the details of the case, Lin He teamed up with He Zhizhi, a computer genius who had been deaf in his left ear since childhood, and found the female spy hiding in the country. They followed the clues and finally captured the boss behind the scenes. The solving of the major case also deeply ingrained the words "national security" into the hearts of every Chinese citizen.
