Guan Xue had an informant named Squirrel on the mountain. She asked Squirrel to find out who was helping them escape from the Epidemic Prevention and Water Supply Department if there were people with children going up the mountain. Qian Chongli took Dr. Shi and the children up the mountain and emphasized again that the escape process could not be disclosed to anyone.
Song Zhuowen went to inquire about the time when Hu Bin returned home, and then began to speculate on the location where Hu Bin hid the gun and decided to investigate quickly. Guan Xue's mind was confused as soon as she encountered Guan Kai. Song Zhuowen said that he was a member of the family after all. Qian Chongli was very surprised when he met a squirrel on the mountain. He was a hero of the Anti-Japanese War. Dr. Shi was infected with the Japanese plague. He left a message and left. He didn't want everyone to find him or touch his things. Qian Chongli risked his life to go up the mountain just to find the mole in the team. Squirrel deliberately led the clues to Song Zhuowu. After all, it was because of his trouble last time that he failed to find the mole.
Song Zhuowu has been checking Hu Bin's relationship network, and tomorrow is the day when Hu Bin and Guan Xue get married. Hu Bin came to Guan Xue with a wedding dress, but when he saw Song Zhuowen drinking coffee at her house, his face immediately fell to the ground and asked Song Zhuowen to go out. Qian Chongli eliminated all the impossible people and finally targeted Song Shu, but he did not expect that he was the traitor in the team. Song Shu is a Manchu, and he does not consider himself a traitor. After all, he is not even a Han. Qian Chongli was heartbroken, no matter whether he was Manchu or Han, he was still Chinese! The land in my hometown was robbed by the Japanese, the men were killed by the Japanese, but the squirrel is here doing things that are unworthy of the country! Political Commissar Fang didn't expect that he had been lying to him, and he cried very sadly. Qian Chongli and Political Commissar Fang thought about it and decided not to kill Song Shu. He was not really a traitor, and he had a strong intelligence network in his hands.
Song Zhuowen found out about Hu Bin's cousin Dong Xu. Hu Bin was most likely to hide the gun in his house, but they did not find the gun in Dong Xu's house. Song Zhuowen realized that he had found the wrong person, but what happened to Hu Bin? Where did you hide the gun? Guan Kai anxiously waited for news about Song Zhuowen by the phone, but then Section Chief Asano called. Because he didn't get Guan Xue's invitation, he learned about it through Hu Bin's invitation, so he declined everything to attend tomorrow. Guan Xue and Hu Bin's wedding.
Tonight, Song Zhuowen led people to search all over Hu Bin's network. Hu Bin called early the next morning and said that he would take Guan Xue to the church. Guan Xue did not receive any news from Song Zhuowen and could only go to the church in her wedding dress. Only then did Song Zhuowen realize that he was going in the wrong direction. The most dangerous place in Harbin was where the Japanese were. At the wedding, Hu Bin urged to start as soon as possible, but Guan Xue said to wait. Xie Yue came to the anxious Guan Kai, with a bit of pride on her lips. The wedding started, and the priest presided over Guan Xue and Hu Bin to say their vows to each other. However, Song Zhuowen came to stop it at this time. He whispered to Guan Xue that the gun had been found and was in the Yamato Hotel. Guan Xue left the scene triumphantly. No man could marry her, and she would not marry any man.
