Li Xiqian saw the murderer kill everyone who was with her, but she survived. Liu Xiuyue was responsible for investigating her, but he kindly reminded Li Xiqian to pay more attention. President Long’s drug manufacturing plant is still manufacturing drugs, but the rats who stole the goods still exist. She ordered all the goods on the market to be recycled. By then, whoever is still selling the goods will definitely be the rats. Liu Xiuyue and Liang Zaishan are investigating the car accident. The most valuable is only a photo of the witness of the case, but the other's face was blocked by the hand. K found that this man's bracelet was very familiar, and took Liu Xiuyue to Officer Lin's nightclub.
Lin Warning still hated the incident that Liu Xiuyue smashed this place last time, and directly beat Liu Xiuyue, and then the other party gave him the settlement list for that night. After all, this case has a major relationship with Li Xiqian, and she also came to investigate the case with Liu Xiuyue. After the efforts of the two, the witnesses were finally found. But he said that he hadn't seen anything. K's personality got excited, and he grabbed the other's collar, and Li Xiqian hurriedly stopped. Liu Xiuyue's personality changed back to dominance, and she quickly let go of the opponent. This is not the way to go, Liu Xiuyue went to the doctor again, wanting to get rid of the K-personality.
K personality also wants to get rid of Liu Xiuyue, in the eyes of the doctor, it is Liu Xiuyue who is acting alone. The doctor said that before he could treat a disease, he had to remember what happened when he was a child. Because of the appearance of multiple personalities, most of them were because of childhood injuries. Liu Xiuyue agreed with both hands, but K's personality uncharacteristically refused to treat the illness. After K’s personality was gone, only Liu Xiuyue was left to treat the illness. He went into a dream after being hypnotized by the doctor. He saw a lot of rooms, but before he found any clues, he was awakened by a burst of stimulation. The doctor was serious. Ask him if he lost his memory when he was a child.
Wu Jingtai was assigned to work in the second group of the Anti-Corruption Investigation Division of Wenyang Police Department, and he happened to be under Liu Xiuyue. After Li Xiqian was busy at the funeral of Kim Kyung-joon, he was going to go home to freshen up and go to work. He just returned home and found that there were many policemen at home. Liu Xiuyue was on the phone with her and rushed over when she heard the movement. The police received a report saying that there was a thief here, so they came in and searched. Unexpectedly, they found a box of drugs in Li Xiqian's room. Both Liu Xiuyue and Liang Zaishan suspect that there is a ghost in the anti-drug team, but until now, Li Xiqian is still unwilling to doubt his colleagues who have worked with him for a long time.
After Li Xiqian's home found drugs, Jin Jizhi found Xu Zonggu and slapped him severely. It turned out that in the entire anti-drug team, except for the dead Jin Jingjun and Li Xiqian, who was behind the scenes, everyone else was a ghost, including the leader Jin Jizhi. Liu Xiuyue went to find Kong Zhenyu again. This time he finally told the truth that he did see the murderer. After the murder, he left in an ambulance. At the same time, Wu Jingtai also investigated a suspicious ambulance with a fake license plate. President Long's people caught Jin Jizhi's people. In order to save his life, Jin Jizhi was willing to get rid of Xu Zonggu to show his sincerity.
Liu Xiuyue and the others found the ambulance placed in the abandoned car yard and found the face of the murderer Zheng Rixiu from the dash cams of the surrounding cars. Wu Jingtai ruled out that there was an abandoned car park company that had just been cancelled. The legal person happened to be Zheng Rixiu's junior high school classmate. Liu Xiuyue entered this parking lot alone, and she found a clue. K and him worked together to beat all the people here, but Zheng Ri Xiuyin still gave him a shot, and the other party gave him an anesthetic. When Liu Xiuyue woke up, she found that she was tied up, and she also saw Jin Jizhi, Zheng Zanqi and Xu Zonggu from the anti-drug team.
Jin Jizhi killed Xu Zonggu. He also wanted to kill Liu Xiuyue, but Liu Xiuyue admitted that he would help him cross the sea. In the end, Jin Jizhi released him, but he left evidence that he could frame Liu Xiuyue, so that Liu Xiuyue didn't dare to talk nonsense after going out. The case was quickly closed. K-Personality couldn't understand Liu Xiuyue, and fight with him on the rooftop. Liu Xiuyue couldn't help it. After all, he was threatened. After that, Liu Xiuyue went to the prison to see Li Xiqian who was being held, and her words suddenly reminded Liu Xiuyue. Liu Xiuyue revisited the case data of Zhuo Minshui's murder and found a key piece of evidence. He decided to re-investigate the case, and to investigate together with K-Personality.
