Xiong Kuohai never expected that Lao Pan came to Tianjin to continue the beheading operation. Lao Pan explained to Xiong Kuohai the real reason for the assassination of Kato — there was a comrade lurking in the high-ranking Japanese army in Shanghai. Once Kato came to Shanghai to perform his duties, this comrade must reveal his identity, so Kato must die in Tianjin.

After being instructed by his superiors, Xiong Kuohai was able to stay in Tianjin to fight alongside Lao Pan. Lao Pan established a liaison station Tiancheng Tea Shop in Nanshi, equipped with a radio station and traffic crew, and ordered Xiong Kuohai to start work. At this time, Yan Yan had recurrence of asthma. Seeing her daughter’s condition worsening, her husband was silent again. In desperation, Zhou Shuzhen could only return to Tianjin with Yan Yan for treatment. Xiong Kuohai used the radio from Tiancheng Tea Shop to forward the new information of “Akamoto’s Revenge” provided by Kamei to his superiors. He watched the intelligence line he had set up in action and thought that Ji Deping had not sacrificed in vain, Xiong Kuohai was extremely relieved.

Yanyan was admitted to the hospital and her condition was under control. Zhou Shuzhen still had no news of Xiong Kuohai and could only turn to Anderson. He tried his best and complained about Xiong Kuohai regardless of his family. Yang Xiaoju desperately wooed Pei Yanling, hoping that she would fill in the party application form and officially join the military organization.

As the traitor was informed, Kato learned that the Chinese Communist Party had sent someone to the Tianjin Hotel to connect with the medal, and ordered Ota to start the operation immediately. Upon hearing this news, Kamei immediately rushed to Tiancheng Tea Shop to report that Xiong Kuohai rushed to the Tianjin Hotel to notify Lao Pan, but unexpectedly the Tianjin Hotel was surrounded by Japanese military police. Comrades Lao Pan and Peiping came to battle with the Japanese army in the Tianjin Hotel, and the two of them died at the end.
