Zhu Feng, who was doing economic work for the organization in Hong Kong, was ordered to urgently purchase a batch of penicillin to support the Fujian front line. Faced with the tight foreign exchange situation, Zhu Feng thought of soybeans from the liberated areas... His superiors arranged for Wu Shi's old friend He Sui to escort him. He Sui had already established an East China Sea intelligence team in Taiwan. Wu Shi could only collect intelligence.Unexpectedly, He Sui's son He Kang's identity as a Communist Party cadre at the Shanghai Naval Management Committee was exposed, and He Sui had to evacuate hastily.

The heavy burden of the Donghai team suddenly fell on Wu Shi's shoulders.Just when Xiamen was liberated and Kinmen, which was just around the corner, became the turtle in the urn of liberation army, Wu Shi learned that two armies of Hu Lian rushed to aid Kinmen.Wu Shi was extremely anxious. In order to send this urgent information, he took the risk and asked Nie Xi to meet with traffic officer Zhang Hao.In front of National Taiwan University Hospital, Wu Shi took advantage of the opportunity to see a doctor and contacted Zhang Hao. Unexpectedly, Zhang Hao had already been targeted by Gu Zhengwen, head of the Secrecy Bureau's detection and prevention team.
Wu Shi knew that Zhang Hao had been exposed, so he asked Zhang Hao to kidnap him and take the opportunity to escape by car.Unexpectedly, Gu Zhengwen actually fired at Wu Shi's car. The car was shot and broke down. In order to protect Wu Shi's safety, Zhang Hao resolutely raised his gun and committed suicide. Wu Shi saw his comrades sacrificed but could not show any sadness.When Mao Renfeng learned about it, she was furious. There was no evidence and no solution. She was stunned to offend Wu Shi, a big shot, and called to apologize.
