In the tea house, Xi Mengying said goodbye first, and when he passed by Li Bing's side, a faint elegance on Xi Mengying's body floated into Li Bing's nose.

Li Bing didn't feel it at that time, first felt that this fragrance was refreshing, and then felt that this fragrance seemed to have smelled somewhere.

He stared blankly at the tea in front of him until everyone was making fun of him, and when he looked up and saw Team Song, a flash of inspiration suddenly flashed in his mind.

That's right, isn't Team Song worrying about Xiao Keyi's bizarre throat cutting case? Li Bing suddenly remembered that he had smelled this fragrance in the corridor of Xiao Keyi's house on the night of Xiao Keyi's accident.

Zhao Wan'er asked in surprise, "Li Bing, you don't have a high fever, do you?" Just because you smell the perfume on Sister Mengying's body, you are sure that Sister Mengying is the murderer who killed Xiao Keyi? ”

Li Bing said: "Wan'er, no, you let me think about it again." By the way, what's the name of the perfume? To be honest, it smells pretty good. ”

Zhao Wan'er snorted and said: "This is Chanel No. 0 perfume, which is a men's type, but many people say that women, especially those in the workplace, will make people feel more attractive." ”

Li Bing closed his eyes and was silent for a long time, and then he opened his eyes and said slowly to Team Song: "Team Song, I'm almost sure that Xiao Keyi's death has nothing to do with ghosts, this is a man-made murder, and the murderer is Xi Mengying, who takes care of her daily life. ”

Xiao Song was pleasantly surprised, couldn't resist the excitement in his heart, and asked in a trembling voice: "Li Bing, tell me about your discovery, if it is really deduced by you, then this bizarre case can be closed, I have to thank you very much." ”

Li Bing smiled slightly and said: "As Wan'er said just now, the perfume smell on Xi Mengying's body is Chanel Zero, which is obviously different from the perfume smell on Wan'er and Sister Shi." I asserted that Xi Mengying was the murderer, because I smelled the perfume on the night of Xiao Keyi's accident. ”

Zhao Wan'er said in confusion: "Li Bing, don't mislead Team Song, and don't wronged Sister Mengying?" This is a major matter of human life, and there is no room for blind suspicion. That night, Sister Mengying stayed in the same room as us, how could you smell her perfume? ”

Li Bing smiled: "The key is here!" Wan'er, did you, Sister Shi and Xi Mengying fall asleep early that night? ”

Zhao Wan'er nodded, and Li Bing continued: "That's right! That night, in a daze, I heard what seemed to be a strange noise outside. Seeing that Brother Zhang and Brother Qian were both asleep, they were snoring beautifully, and they were not sure if I had heard them wrong, so they didn't wake them up. ”

"First, I was suspicious, and second, I was in a hurry, so I immediately thought of the bathroom in the living room on the second floor. When I crept to the corridor on the third floor, and was thinking about getting to the second floor, I smelled a strange smell on the side of the corridor. At that time, I wondered, what smells so good? I just understood that it turned out to be the smell of Chanel perfume on Xi Mengying's body. ”

Zhao Wan'er was even more surprised, almost unable to believe what she heard. She said hurriedly, "How is this possible? Sister Mengying fell asleep with us, no matter how strong her perfume smelled, it was impossible to keep it at the top of the stairs forever! ”

Li Bing smiled slightly and said, "Wan'er, don't worry. Let me ask you first, did you and Sister Shi sleep until dawn that night, and felt that they slept very soundly? ”

Zhao Wan'er and Shi Liya nodded at the same time, and Li Bing continued: "Brother Zhang and Qian Yiduo are the same, even including me, although I came out in a daze and relieved once, but after returning to the room, I still fell asleep all of a sudden." If we say we're tired, we'll have this reaction, can you believe it? The group felt very sleepy, which was almost impossible before. ”

Xiao Song's eyes lit up, and he asked eagerly, "Li Bing, do you mean that Xi Mengying took advantage of the opportunity to make dinner for you and drugged you in dinner?" ”

Li Bing said: "Yes, this is the most reasonable explanation. She must have known the medicinal properties of that medicine in advance, so not long after we had dinner, she deliberately pretended to be scared, and finally achieved the goal of staying in the same room with Wan'er and Sister Shi. ”

"As long as the drug has a seizure, when we all sleep deeply, that is when she kills Xiao Keyi. And she skillfully lived in the same room with Wan'er and Sister Shi, which was to use us, especially Wan'er and Sister Shi, as her witnesses to rule out her suspicion of committing the crime. ”

Li Bing suddenly stopped talking and asked Team Song: "Team Song, after Xiao Keyi's death, did her corpse report mention that Xiao Keyi had medicinal ingredients in her body?" ”

Xiao Song nodded and said, "Yes, and it's a psychotropic drug." However, this is not surprising, because Xiao Keyi has developed mental problems, and recently, whether it is according to the doctor's order or the request of her personal doctor Xi Mengying, she has to take psychotropic drugs every day. The forensic doctor also checked the medicine that Xi Mengying gave her according to the detected residual medicinal properties, and there was nothing wrong, so Xi Mengying's suspicion was also ruled out. ”

Li Bing shook his head and sighed: "Poor Xiao Keyi, I now believe that everything she said is true, and it is definitely not her hallucination, let alone her mental problem. Remember when we first came to meet her? Aren't we all surprised, why is Xiao Keyi, who suffers from mental illness, her eyes are still so clear? Now I understand, Xiao Keyi is not crazy at all, she was framed by someone and was 'been' mentally ill. ”

Everyone was very surprised, recalling that Xiao Keyi, who was as beautiful as a fairy, if it was really a conspiracy to be killed, it would be really regrettable.

Li Bing looked at everyone, waved his hand, and signaled everyone not to get excited, so as not to disturb his train of thought. After everyone quieted down, Li Bing pondered for a while and continued: "Maybe my appetite is not as much as that of Brother Zhang and Qian Yi, so I have taken relatively little medicine; The physical fitness is better than that of Wan'er and Sister Shi, so after the four of them fell asleep one after another, although I also felt dazed, I fell asleep relatively later than them. ”

After Wan'er and Sister Shi fell asleep, Xi Mengying quietly slipped out of the room. Because she was going to carry out the long-planned murder of Xiao Keyi, although she drugged us, she was still cautious, so she sneaked out of the room without turning on the light. When I heard something strange and got up and walked to the staircase, I passed by the room where Wan'er and the others lived, and I didn't notice any light coming through the crack in the door. ”

"I guess that Xi Mengying gave Xiao Keyi drugs that can produce mental hallucinations, leaving Xiao Keyi in a state similar to sleepwalking. She induced Xiao Keyi to leave her room and go up the stairs to the hall on the ground floor. Her main purpose was to lure Xiao Keyi to the parking lot. ”
