Chen Jiaping woke up from a nightmare and saw that Zuo Shuangtao was safe and sound, but he just closed the window. He told Zuo Shuangtao not to fall down after closing the window. Du Chun and Xiao Duan of Hongyun Hotel were rescued. Three groups of people came and hit them with two knives. When Zhao An arrived at the hotel, the place was already in flames, and no one knew where they had been rescued. Zhao An suspected that the Four Clubs were Luo Guanqun's men. Luo Guanqun should have known in advance that the person was hiding here, so he wanted to rob the person and ruin Zhao An's big event, but he didn't expect that the four clubs would bring him a yellow bird behind him. Zhao An failed to do his job well, so Kimura Kenzo tied him behind a horse and threw him a newspaper. In order to save his life, Zhao An shouted that he knew who the Four Clubs were.
Kimura Kenzo asked Chen Jiaping to come over, and Zhao An said he wanted to hear Chen Jiaping's story about the Four of Clubs. Chen Jiaping was calm and composed, listening to how Zhao An determined that he was the Four of Clubs. At this time, Zhao An took out the miniature camera and said that it was something thrown by the Four of Plum Blossoms in the villa. The camera must have the fingerprints of the Four of Plum Blossoms. Feng Qi took Li Youtian back to Shanghai Taihe Bank and asked someone to help keep an eye on Li Youtian. Then he went in and reported to Kimura, saying that Zhao An's investigation was completely wrong. Zhao An only focused on checking Chen Jiaping, but ignored the nun who rescued Jiang Zhaoguo that day. So Zuo Shuangtao was also brought over, and Feng Qi confronted her and explained the situation that day to Kimura Kenzo. What Feng Qi said was quite accurate and well-founded, but all of this was his one-sided statement.
Chen Jiaping stepped forward to defend Zuo Shuangtao and asked Feng Qi to provide evidence. Feng Qi couldn't provide any evidence, but he had other evidence that could prove that Zuo Shuangtao was a military agent, and that evidence was the sachet. Yunjin craft sachets are only sold at Nanjing Pukou Station, which means that Zuo Shuangtao got on the bus at Nanjing Pukou Station, not from Wuhan as she said. Feng Qi has brought the sachet vendor to Shanghai, and he can identify Zuo Shuangtao. Zuo Shuangtao was nervous and squeezed Chen Jiaping's arm. The frog guarding vendor Li Youtian was beaten to death, Li Youtian ran away, and Feng Qi failed to bring him to Kimura Kenzo. Chen Jiaping then began to provide clues in an orderly manner, asking Kimura Kenzo to look at Jiang Zhaoguo's photo in the newspaper and see how he was bandaged.
Jiang Zhaoguo's right arm was injured and he was bandaged using a figure-eight spiral bandage. Zhao An remembered that last time Feng Qi said that his girlfriend taught him the figure-eight spiral bandage. Chen Jiaping added that there are very few people in China who know the figure-eight spiral bandage. As for Li Youtian, he was just a small vendor. How could he snatch Frog's gun and kill him? The only explanation is that Li Youtian was the person Feng Qi brought to frame Zuo Shuangtao, but he showed his flaws while waiting. , so he killed the frog and escaped. At this time, Damasao came and provided an important note, which was picked up at Hongyun Hotel. The note was Feng Qi's handwriting. Zhao An identified Feng Qi as the CCP undercover Four Clubs. Feng Qi jumped over the wall in a hurry, bit Zhao An's arm, and took Kimura Kenzo hostage.
Then Feng Qi said that Kimura Kenzo could be released, but Zuo Shuangtao must be replaced as a hostage. Chen Jiaping pretended to agree, and when throwing lipstick to Zuo Shuangtao, he seized the opportunity to pick up the gun dropped by Kimura Kenzo on the ground and killed Feng Qi. Zhao An has since lost trust in Kimura, and Luo Guanqun is very proud. Chen Jiaping told Lao Lu about his experience in the villa. He hid the set of films in the ring box that Jiang Zhaoguo was going to give to Han Lu. Later, Han Lu did not leave Shanghai and he successfully got the films back. Chen Jiaping has a bold idea to win over Zuo Shuangtao. Lao Lu personally disagrees, but he will truthfully report Chen Jiaping's proposal to his superiors. In addition, Chen Jiaping also has a task related to a platemaking expert named Zhu Yuhua.
Although on the surface Feng Qi is the Four of Clubs, Zuo Shuangtao is very smart. She raised another possibility, that is, someone knew Feng Qi's eight-character spiral bandaging method in advance and deliberately conspired with Jiang Zhaoguo to frame Feng Qi.
