In the late period of the War of Liberation, Sha Bingzhang, the commander of the new B Army, was transferred to Fengcheng, and the KMT Security Bureau also transferred Lu Minzhi to Fengcheng. Her first task was to investigate whether Sha Bingzhang had the intention to surrender to the Communist Party. Yoko Yamano came to Fengcheng secretly. Her purpose was to follow the order of her father, Seiichi Yamano, to carry out a BBURH operation and find the germ bomb left by her father in Fengcheng. Qi Zhongfei, as a member of our party's underground organization, has been lurking around Sha Bingzhang for many years. Although Sha Bingzhang is a famous anti-Japanese general, he has suffered from suspicion within the KMT. Qi Zhongfei has been observing Sha Bingzhang's every move and plans to let Sha Bingzhang revolt and surrender to the Communist Party. The germ bomb seized by Sha Bingzhang during the Anti-Japanese War has always been his secret trump card. In the end, Sha Bingzhang led his troops to revolt after careful consideration, and the germ bomb was handed over to our army for proper disposal.
