Yu Chunyang showed hesitation in the face of Ida Yutaro's invitation, and Ida Yutaro put forward very generous conditions. When Yu Jiazi returned to China, Yu Chunyang could go back to school at any time, and Yu Chunyang readily agreed. Chen Qian came to the hospital, Ida Yutaro hoped that he would ask Yukako about the whereabouts of Park Caiying, maybe she would be willing to tell Chen Qian. Yu Jiazi didn't want Yutaro Ida to know the whereabouts of Park Caiying. She was her good friend and Yu Chunyang had already gone. If Chen Qian went with her, she would be relieved. When Chen Qian went to that place, Yu Chunyang had already moved Park Caiying safely. She went to find her mother, but when she arrived, her mother was already dead.
Chen Qian and Yu Chunyang checked the scene again and believed that Pu's mother died of poisoning. Chen Qian quickly found the whereabouts of Xie Dongdong among the things left behind at the scene, and he was the one who organized the arrangement. Xie Dongdong didn't think Yu Jiazi was innocent, and the reason why he killed Park Caiying's parents was because they didn't follow his original plan. Xie Dongdong claimed that he was helping Chen Qian. After such a toss, Yutaro Ida would definitely trust Chen Qian. Chen Qian didn't appreciate it, and he was almost killed.
Chen Qian went to pick up Yu Chunyang to Yu Jiazi's house, and Yu Chunyang guessed that he had found the murderer behind the scenes. Now they are grasshoppers on the same rope. Chen Qian said that if Yu Chunyang told him about Park Caiying's whereabouts, he would at least give Yu Jiazi an explanation. After Jiazi came home, she was bored in the room, and she didn't feel happy until she saw Yu Chunyang. Yutaro Ida wanted to recommend Chen Qian to the Political Security Bureau as the chief inspector, because the task of searching for uranium ore could not be carried out, so Chen Qian agreed. Chen Qian went to find Wu Ruonan, Chongqing replied that he had no knowledge of Xie Dongdong's matter, Chen Qian felt that he should tell Qiu Yingxia. Yutaro Ida may not be completely relieved of Chen Qian. Although the Political Security Bureau does not get any information, it is the safest for Chen Qian now.
Qiu Yingxia and Guan Yongshan reported about Xie Dongdong, Guan Yongshan could only tell the truth that Xie Dongdong was sent to Shanghai by himself, but he knew nothing about his actions, and said that Xie Dongdong would be dealt with severely. Xu Dehai learned that Yu Chunyang lived in Ida Yutaro's house, but he was very worried that she and Chen Qian would show their feet, but Yu Chunyang and Chen Qian rarely met at home. Chen Qian met Gu Manli in the Political Security Bureau, and she fully demonstrated her duty of picking flowers in the private parts of a playboy. Captain Zhou was very depressed when he saw this, but he had to nod and bow to Chen Qian.
He Dabao deliberately mentioned Gu Manli in front of Chen Qian. Everyone in the bureau knew that Captain Zhou liked Gu Manli. Chen Qian said that he could give him some advice, and they would meet at the banquet in the evening. Captain Zhou and He Dabao thanked each other and left. Chen Qian saw today's crackdown on the G Communist Party in the task report given by Captain Zhou.
In the evening, Ida Yutaro hosted a banquet, and Wanfu was also very humble to Chen Qian. Chen Qian asked Captain Zhou to ask Gu Manli to dance, but Captain Zhou said she couldn't dance, so no one could ask her to dance. Chen Qian made a bet with Captain Zhou that if he could ask Gu Manli, Captain Zhou would help him with a personal matter. Chen Qian went to look for Gu Manli with a wine glass, and deliberately revealed the pin mark that Gu Manli had left when she saved her. Gu Manli also saw it. Gu Manli rejected Chen Qian because she couldn't dance, but they were grasshoppers on the same rope, and Gu Manli had to stand up to cooperate with Chen Qian in acting. Gu Manli could recognize Chen Qian, and he would inevitably show his feet in front of the Japanese. Gu Manli advised him to be careful.
