Four people came to the crime scene together in the sixth episode. That is a villa. The owner of the villa is a designer. In order to debut for ten years, 10 new models were called for selection, and five of them were eliminated. One of the remaining five died, named Han Meina. The medical examiner said he fell to his death. The forensic doctor told Min that if there was no evidence of homicide, the family of the deceased would not agree to the autopsy. And gave the blood of the deceased to Min Jian. Min Jian drank the blood and saw through the sight of the dead that the things in his hand were taken away. Sheriff Huang analyzed the possibility of homicide in this case. Models in the villa are not allowed to bring mobile phones, while the deceased took a mobile phone and talked to a man named Park Ji-won (the boyfriend of the deceased) 30 minutes before he died. Yu Jian, Dong Wan and Min Jian questioned the three points mentioned in the conversation, namely "thing", "other" and "danger". Because of these three factors, Huang Jing decided that the case was homicide. All three looked at Yu Jian. Let Yu Jian lurk as a model. Yu Jian made various excuses, but all failed and finally "compromised". Yu Jian lurks the same model as Yu Jinglan. Because of the autopsy, the forensic doctor asked Xiao Zhi, who was doing homework, to go home first. Xiao Zhi met two guys with guns. She looked back and didn't care. The forensic doctor was preparing an autopsy when two guys with guns broke in and hit the forensic doctor on the forehead, bleeding. The forensic doctor was forced to dissect at once with a gun. They wanted to take what was in the stomach of the deceased, but they refused to say what it was. At the same time, there were also gunmen who hijacked the designers and models present. Yu Jian didn't come out in the bathroom. They haven't found Yu Jian for the time being. Xiao Zhihui suddenly remembered that he forgot to bring his pencil case when he walked, so he went back. Yu Jian, who was hiding in the bathroom, kept calling Dong Wan, but no one answered, because Dong Wan and Huang Jing were fishing by the lake and their mobile phones were in the car. Yu Jian was discovered. Jin Jingmin told Yu Jian the whole story. A few months ago, a man named Jin Shangxian approached Jin Jingmin and several others, saying that he would rob the jeweler, and that he would share one-seventh of the account equally. As a result, Jin Shangxian got the real diamond himself and gave it to others. Then they arrested Jin Shangxian and beat him up. He said that the diamonds (worth 5 billion yuan) were in his home, but at that time, Jin's home had been auctioned and the buyer was a designer. So Jin Jingmin worked here, because the staff could not enter and leave the house where the model lived at will, so she found the deceased Han Meina. But Han found the diamond. He wanted to keep it for himself and didn't want to give it to Kim. Kim asked who Han gave the diamond to, and Han said that this person's name was on this note (the note in her hand), and then she swallowed it. An hour later, Han died. Jin asked Yu Jian to find the man the deceased said within two hours. Xiao Zhi returned to the forensic doctor, who was also hijacked by gunmen, threatening the forensic doctor to dissect quickly. Min Jian came outside the autopsy room, pushed the door and found that it couldn't be pushed open, which was very strange. Xiao Zhi heard the sound of pushing the door and called for help. Before she finished, she was covered with her mouth. Min Jian felt the blood on the forensic doctor's head. Min Jian came in for wisdom. Min Jian asked the gunman to explain what was going on. Jin Jingmin didn't ask about the whereabouts of the diamond. He was going to take Yu Jian's operation and point a gun at Yu Jian's head. Just then someone knocked at the door. This man was one of the gunmen around the forensic doctor. The man looked flustered. He also said that he killed the policeman because he pressed the wrong button. Min Jian reported the situation to Minister Zhu. Minister Zhu said that the diamond hidden in the lamp is worth 654.38+0 billion, and there must be 4 billion. The remaining 4 billion diamonds are on the black dress with suspenders worn by Yu Jian. It turned out to be Han Mina's clothes. Han Meina asked the designer to help her design clothes, and also set a black diamond on the clothes that money can't buy. The skirt was thrown aside by Yu Jian. Back to the police station during the day. Dong Wan and Huang Jing knew that they had made a mistake and made fish to please Yu Jian. Min Jian went back to his office and saw an envelope on the table. He opened it and found that the photos of forensic doctor, Dong Wan, Huang Jing and Yu Jian were all cut by knives, while Min Jian was associated with a red-eye vampire.
