While Gu Xixing was sitting quietly at home, worrying about his children, two women suddenly came to visit, one of whom claimed to be his future daughter-in-law Haimo. After some questioning, the truth came to light. It turned out that Haimo was actually the daughter of Yuquan, a classmate of Gu Xixing's military academy. The two families met by chance and had made an engagement early in life. However, Gu Xixing knew that his son already belonged to Xiao Ruotong in his heart, so he felt deeply sorry for Haimo. Although Haimo didn't say much, his cousin-in-law, Mrs. Weng, who was traveling with him, could not conceal his dissatisfaction and accused Gu Xixing of being ungrateful. Gu Xixing knew that he was in the wrong, patiently explained the whole story, and invited them to stay at Gu's house temporarily.
In fact, Mrs. Weng's true identity is Quanshui, a Kuomintang military reunification agent. She came to Suzhou this time to connect with Zhou Zhifei. But Zhou Zhifei knew very well that he had embarked on the road of Han Dynasty, and it was difficult to turn back, and he was full of worries. He was unwilling to face the embarrassment of rekindling his old love, and he was also worried that Quan Shui was the killer who was ordered to come to kill him. In addition, Quan Shui is the number one secret agent around the president, so his purpose is even more mysterious and dangerous. Therefore, Zhou Zhifei acted cautiously and sent his confidant Jin Jiang to meet with Quan Shui on his behalf to explore its reality. Behind this undercurrent of the meeting, various forces are intertwined and each has their own agenda. A contest about loyalty and betrayal, emotion and reason quietly unfolds.
When Gu Yizhong and his party stepped into the base area, what greeted them was not a warm embrace, but strict censorship and isolation. Their guns were confiscated, and the four of them were arranged to live separately. Such treatment made Gu Yi feel mixed emotions in his heart, and he felt an inexplicable feeling of suspicion and rejection.
Wang Zhiming, the enemy engineering section chief of the New Fourth Army, personally went into battle and conducted a detailed review of Gu Yizhong and others. When they learned that they had doubts about the identity of "Eagle", Section Chief Wang smiled slightly and revealed the answer to everyone - the comrade in military uniform was the "Eagle" they called, his real name was Zhou Zhenwu, a member of the New Fourth Army The secret liaison in Suzhou usually uses his identity as a clerk at Liangyou Coffee Shop as a cover. This news shocked everyone. It turned out that all the previous speculations and misunderstandings were due to ignorance of the truth.
Zhou Zhenwu further revealed that he had secretly observed and protected Gu Yizhong and others at many critical moments. Whether it was Xiao Ruotong taking Gu Huizhong's bracelet to Zuixian Tower, or whether Gu Yizhong and Xiao Ruotong visited Liangyou Coffee Shop, he was always present, but he never showed up. Duan Wentao's active exposure was precisely to cover his whereabouts and ensure the smooth progress of the mission.
However, after Gu Yizhong finished recounting his thrilling experiences during this period, Wang Zhiming and Zhou Zhenwu cast a scrutinizing gaze. They began to wonder whether Gu Yizhong was the traitor "Cell No. 8" lurking inside. After all, he was able to miraculously survive being chased and intercepted by dozens of spies, and the New Fourth Army soldier he mentioned who helped him escape has not yet been found. This speculation made the atmosphere suddenly tense, and Gu Yizhong faced an unprecedented crisis of trust. He knew that only by proving his innocence through practical actions could he break the haze hanging over his head.
When Gu Yizhong and others stepped into the base area, they were greeted by strict censorship and isolation. The guns were confiscated and the four people were forced to live separately. Gu Yi felt mixed emotions in his heart and felt deeply suspected and excluded.
In addition to the murdered New Fourth Army soldiers, radio stations and messages were also found in Gu Yizhong's room. The evidence was conclusive and he could not defend himself. Zhou Zhifei received the No. 8 cell telegram, confirming that the New Fourth Army base was on Chongshan Island, and then forwarded it to Masao Kondo. The Japanese army launched a three-pronged attack on the base area by sea, land and air. Wang Zhiming urgently warned Xiao Ruotong and others to evacuate, and declared Gu Yizhong a traitor and would be shot. Xiao Ruotong and Gu Huizhong strongly support Gu Yizhong and firmly believe in his innocence. Just as they were defending themselves, Japanese bombers roared in, and the sky was shrouded in war clouds.
Xiao Ruotong was so anxious that she broke down the door and rescued Gu Yizhong. Facing Zhou Zhenwu's gun, she stood up to protect him and urged Gu Yizhong to run quickly. After Gu Yizhong escaped, he met Gu Huizhong and Hu Zhiping who were expecting childbirth. He resolutely decided to distract the Japanese army and let the two escape by boat. On the lake, a baby's cry sounded, which was the hymn of life and the peace in Gu Yi's heart. He knew that his sister had given birth safely, and his heart finally fell.
