Ono expressed his friendship to Gu Yizhong with sushi as a gift, and Gu Yizhong gave Haimo's carefully made pastries in return. After dinner, Ono expressed his strong interest in the art of Pingtan. After some humility, Haimo was finally moved by his sincerity and agreed to teach him. On the way home, Gu Yizhong was a little worried, thinking that Hai Mo was too rash, but Hai Mo disagreed, and then spent a leisurely mahjong time with Yu Qing and others. From Yuqing's mouth, Haimo learned that Xie Wenchao had gone to Shanghai. This news made Gu Yizhong alert and had a bad feeling.
In the dead of night, Gu Yizhong was awakened by a nightmare. When Haimo asked with concern, Captain Zhang suddenly broke in with his men, breaking the tranquility of the night. This scene made Gu Yizhong even more convinced that there was an undercurrent surging beneath the calm, and a storm might be coming.
While being escorted, Lao Huang took advantage of the agent's unpreparedness and suddenly attacked the driver, causing the situation to get out of hand. In Zhou Zhifei's office, he was immersed in imagining Gu Yizhong's reaction after his identity was revealed. Unexpectedly, Xie Wenchao broke in hastily, bringing the bad news that Huang was dead and taking the body to the interrogation room.
Captain Zhang then led Gu Yizhong to No. 90, preparing for the so-called "identification". Facing Lao Huang's body, Gu Yizhong was filled with shock and grief, but he suppressed his emotions and remained calm. Seeing this, Zhou Zhifei deliberately mentioned his old relationship with Lao Huang, trying to touch Gu Yizhong's emotional defense line, and guided him to observe the fatal wound on Lao Huang's neck to test his reaction.
Gu Yizhong responded tactfully, avoiding a direct answer on the grounds that he did not understand medicine, and then left calmly. Zhou Zhifei stared at Gu Yizhong's back with even more doubts in his heart. He turned to ask Captain Zhang what he thought of Lao Huang's death, and was surprised by Captain Zhang's indifference. Captain Zhang admitted that he had no friendship with Lao Huang, so he naturally felt no sadness. This made Zhou Zhifei even more confused as to why Gu Yizhong's reaction was exactly the same as Captain Zhang's. Despite this, Zhou Zhifei had deep doubts about Gu Yizhong's identity and firmly believed that he was the underground party codenamed "Gu Zhou".
Zhou Zhifei revealed his suspicions about Gu Yizhong's identity to Mr. Li, but Mr. Li had other insights and believed that the closeness between Kondo Masao and Gu Yizhong might have deep meaning or be a plan for the future. He told Zhou Zhifei to shift his focus to win over the 33rd Division, put the matter of the lone boat on hold for the time being, and regard it as a potential weapon.
Mr. Li's family was uneasy, and he had another dispute with his wife over the matter of Lvzhu. Zhou Zhifei suggested that Lvzhu be sent to Suzhou to avoid the limelight temporarily, and asked himself to take care of it. However, Zhou Zhifei is well aware of the complexity of Lvzhu and has learned from past mistakes. Two people have already been punished by Mr. Li for improper handling.
Facing this difficult task, Zhou Zhifei frowned. Upon seeing this, Yuqing smiled slyly and proposed to transfer the "hot potato" of Green Pearl to Gu Yizhong in order to resolve Zhou Zhifei's dilemma. This strategy not only shows Yuqing's wit, but also foreshadows the subsequent plot.
Luzhu arrived in Suzhou and frequently acted coquettishly towards Gu Yizhong, asking for companionship and service, and even verbally teasing her, creating a subtle atmosphere. There were only green vegetables on the dining table. When Gu Yizhong asked why, Hai Mo responded with a jealous tone, emphasizing that light food was better. At the dance, Luzhu refused the invitation of the Japanese colonel and provoked the other party to draw a gun. Fortunately, Ono made a timely rescue and averted a storm.
Gu Yizhong blamed Lu Zhu for acting recklessly, but Lu Zhu ridiculed him for lacking courage. When returning home, Ono arrives unexpectedly and sincerely invites Haimo to sing Pingtan for Nobuo Kobayashi. Hearing Xiaolin's name, Gu Yi secretly rejoiced and regarded it as an opportunity. Ono's visit not only broke the tranquility of the night, but also brought Gu Yizhong a glimmer of hope, making him full of expectations for the upcoming meeting.
