Dive into Memories of the Past

During the Anti-Japanese War, in order to successfully occupy Changsha, the Japanese army used the strategic agent "Black Butler" who had been lurking in China for 15 years to implement a long-planned strategic deception plan. Yun Muzhi, a member of the underground party of the Communist Party of China, was killed during the investigation of "Black Butler". Not knowing his father's true identity, Yun Hongshen returned to his hometown of Changsha in order to track down his father's murderer, and was immediately involved in a trap that had been laid by the "Black Butler". When he was confused and helpless, his father's lifelong friend Yang Ziming, a member of the underground party of the Communist Party of China, gave him great help and protection.
