Gu Yizhong drew a portrait of Liu Qianbao, a spy pretending to be the New Fourth Army, from memory, thinking hard about how to prove his innocence. At this time, Gu Xixing broke in, understood the Japanese army's goals, and decided to help his brother Yi Zhong escape to Hong Kong. He hurriedly ordered Fugui to buy a train ticket, packed his luggage himself, and sent it to the train station. Gu Xixing's move was aimed at keeping Yi Zhong away from right and wrong and ensuring safety.
Gu Yizhong confidently revealed to Gu Xixing that he had found the key to proving his innocence - capturing agent Liu Qiangbao. However, Gu Xixing calmly analyzed and pointed out that even if Liu Qiangbao is captured, the New Fourth Army may not easily believe the words of a person who has been mistaken for a spy. Time was running out, Gu Xixing urged Fugui to send Gu Yizhong to the train station immediately for safety. Just as a group of people were leaving in a hurry, spring water carrying sea foam suddenly appeared blocking the road, and the atmosphere suddenly became tense. Fortunately, Gu Xixing arrived in time and resolved the crisis with his majesty and wisdom, allowing Gu Yizhong to leave smoothly and continue his journey of seeking evidence.
Gu Yi noticed the agents following him on the way and jumped out of the car to escape. Fugui was unable to catch up. When Gu Xixing heard the news, he did not blame the rich and powerful, knowing full well that his son's move was to protect himself. Gu Yizhong fled alone, his life or death uncertain. Gu Xixing was worried but had no choice.
Gu Yizhong quietly approached the No. 90 spy station and saw the agents busily shuttling back and forth, fixing his eyes on the target Liu Qiangbao. He followed behind him calmly, waiting for the opportunity to make a move, and finally succeeded in subduing Liu Qiangbao. After a rigorous interrogation, the truth came to light - it turned out that the thrilling rescue operation was actually a scene carefully planned by Zhou Zhifei. Gu Yizhong asked Liu Qiangbao to record his confession in detail and restrain him properly. Then, he called his home phone number, and when Haimo answered, he told her to go to her room to take out her bank card and go to the bank to withdraw money. Haimo quickly completed the task, handed the money to Gu Yizhong, and tried to ask for his address, but Gu Yizhong did not reveal it, leaving only a simple farewell and hurriedly disappeared into the rain, leaving only the lonely umbrella. Witness this sudden reunion and separation.
Xiao Ruotong was anxious. After learning that Gu Yizhong left without saying goodbye, he immediately went to Gu Yuan to find out the news. However, Gu Xixing's answer disappointed her. Gu Yizhong's whereabouts became a mystery and no one knew. Just when she was filled with disappointment and ready to turn around and leave, the appearance of Hai Mo was like a ray of breeze, blowing away the gloom in her heart. Haimo gently told her that he and Gu Yizhong had met once before, and they agreed to keep in touch by phone at six o'clock every day. This unexpected gain rekindled hope in Xiao Ruotong's heart. She held Haimo's hand tightly, her gratitude beyond words. The two quickly reached a tacit understanding and decided to protect this relationship together. Once there is any news about Gu Yizhong, they will notify each other as soon as possible.
In accordance with the agreement with Gu Yizhong, Haimo quietly came to the place where they last parted, but unexpectedly found several spies gathering at the door of Liu Qiangbao's house. She quickly looked around and recognized the familiar umbrella at the door, and she suddenly had a suspicion in her heart. Facing the interrogation by the agents, Haimo remained calm and lied that Liu Qiangbao had just left, successfully luring the agents away. After the agents left, she quickly knocked on Liu Qiangbao's door. Behind the door, Gu Yizhong and Liu Qiangbao were waiting anxiously.
When Gu Yizhong learned that Xiao Ruotong had come to see him, he felt mixed emotions. He knew that he was in danger at the moment, but he still decided to let Haimo inform Xiao Ruotong and meet him in Zhangji Maple Garden. However, their plan was not completely kept secret. While delivering the message, Haimo was accidentally eavesdropped by Quanshui. Quan Shui quickly informed Zhou Zhifei of the news, and a crisis quietly approached.
Xiao Ruotong and Zhou Zhenwu went to the appointment on time, but were ambushed by Zhou Zhifei. In the chaotic firefight, Liu Qiangbao hijacked Xiao Ruotong in order to protect himself, but was instantly shot dead by Zhou Zhenwu accurately. In the process of escaping, Gu Yizhong accidentally left Liu Qiangbao's confession on the ground. When he realized this and ventured back, his confession had been shot into pieces by Zhou Zhifei with a gun. Seeing that the vital evidence had disappeared into nothing, Gu Yizhong was angry and desperate. He rushed out like a wounded beast, but in the end he was unable to escape Zhou Zhifei's gun and fell in a pool of blood.
