Yan Xinyi held her chin with her hand and had to think about it. What do you think? She couldn't grasp anything specific, where did Ye Mingchao go? She rang the bell and called the waiter, who said that he had not come in, he didn't know what was going on, and he didn't know where Ye Mingchao went.

She could only call Ye Mingchao, and after the phone was connected, it took a while to answer, and it was actually a woman's voice.

"Yan Xinyi, Brother Mingchao is with me, don't come to harass him again." She could hear Sheng Lanting's arrogant and slightly sleepy voice, "Why are you with him?" ”

"You can't care about this, you don't even deserve to lift shoes for Brother Mingchao, wake up early, don't dream!" Sheng Lanting cut off the phone after speaking.

The busy sound of "doodoo" came, Yan Xinyi was simply inexplicable, what happened tonight was so weird, she couldn't understand what was going on at all. But since Ye Mingchao and Sheng Lanting are together, it means that he is fine, and she doesn't have to worry about him. She took out her mobile phone from her bag, did not miss a call, opened WeChat, and there was a message from Zhong Kenan, saying that he was going to work late tonight and asked her to sleep first.

She didn't want to disturb his work, so she decided to go back to sleep first, and wait until tomorrow when her brain was better. She asked the waiter for a bag and put the freshly squeezed juice she and Ye Mingchao had drunk together, as well as two used cups.

Ye Mingchao went to this restaurant to eat for accounting, and there was no need for Yan Xinyi to settle the bill, she left directly with the bag.

Zhong Kenan gave Yan Xinyi a pair of keys to the house, and she could come and go freely. When she got home, after taking a shower, her head was still a little dizzy, and she fell asleep as soon as she hit the pillow.

At the same time, Zhong Kenan and Ding Yiheng were also in the laboratory of Guancheng University to discuss their new project cooperation. Ding Yiheng is a returnee doctor like Zhong Kenan, Ding Yiheng is three years older than Zhong Kenan, and Zhong Kenan is an alumnus of Columbia University in the United States, when Zhong Kenan was studying for a doctorate, Ding Yiheng had already graduated and stayed in school as a researcher. Ding Yiheng has a standard Chinese face, full of heaven, and is very blessed. When he was abroad, he was involved in a scientific research project that used DNA to characterize suspects. Together with other researchers, he analyzed the DNA of 1,000 college students and found that five genes determine 76 percent of hair color, 75 percent of eye color, and 46 percent of skin color. DNA extracted from the suspect's family was later confirmed. They even deduced from DNA from a car left behind at the scene that one of them had blue eyes and dark brown hair.

However, based on ethical considerations, several states in the United States do not allow the police to use DNA to speculate on the racial or physical characteristics of suspects, and the development and promotion of this technology has limitations.

Zhong Kenan knew about the scientific research project that Ding Yiheng had participated in before, but he only understood it, and he didn't think it would have anything to do with him. But on that night in Wushan Village, Yan Xinyi's words touched him greatly, saying that a cigarette butt was found at the scene of the fire where her father died, but it did not match the DNA in the database. It would be nice if the face of the criminal could be reproduced through DNA and the appearance of the criminal could be reversed. In this way, through facial recognition, criminals have no escape.

Yan Xinyi just regarded this as a scene in a science fiction movie, but Zhong Kenan took it seriously, and he thought at that time that maybe he could cooperate with Ding Yiheng and accept a greater challenge, not only to use DNA to speculate the characteristics of the suspect, but to use DNA to derive facial features. If it can be successful, it will have an amazing impact, and it can cooperate with the police, which will provide great help in solving many death cases, and at the same time, it can also fulfill Yan Xinyi's wish for many years.

But using genetic fragments of DNA to infer kaleidoscopic, subtle, and specific facial features is a much more difficult task and a huge challenge. He didn't know if Ding Yiheng was willing to participate, but after the two met, they hit it off and quickly formed a scientific research team. The research funds are mainly invested by Zhong Kenan's company, and geneticists, forensic scientists, and imaging scientists are involved.

After the discussion came to an end for a while, Zhong Kenan came home, it was almost one o'clock in the morning, he took a shower and walked into the bedroom, Yan Xinyi slept soundly, he leaned down very lightly and kissed her face.

At half past one in the morning, Yan Xinyi was awakened by the vibration sound of her mobile phone, and she habitually got up from the bed to answer the call. It's not an urgent task in the bureau, but a call from her mother Qiu Naping. Her heart tightened, and in the middle of the night, something big happened.

"Xiao Yi, can you come to the house right away?" Qiu Naping's tone was hurried, "There is a big incident at home, and your Uncle Sheng doesn't know what to do, so let me come to you to discuss." ”

"Okay, I'll go over right away." Hanging up the phone, Yan Xinyi began to change clothes.

Zhong Kenan had just laid down and hadn't fallen asleep, he insisted on sending Yan Xinyi over, it was not safe to go out alone in the middle of the night. Yan Xinyi had no choice but to agree, she used to often go out to the scene in the middle of the night, she never worried about safety, and she had already cultivated the character of a female man. She felt that she didn't need someone to escort him, and she felt sorry for his lack of sleep, but it was really nice to be loved, cared for, and cared for.

After arriving at the Sheng family's villa, Zhong Kenan drove back, and it was inconvenient for him to follow him in.

Yan Xinyi rang the doorbell, and the maid Ah Cai came to open the door, and under the light, she saw Ah Cai's face pale, as if she was frightened and stimulated.

"What's going on?" Yan Xinyi asked.

"The eldest young master stabbed the second young master with a knife, I saw it with my own eyes......" Recalling the scene at that time, Ah Cai showed horror again, "It's too scary, the second young master is covered in blood......"

Yan Xinyi's heart jumped suddenly, "How is the second young master?" ”

"I was stabbed, covered in blood, and I was taken to the hospital." Ah Cai patted his chest, "How can it be like that, they are brothers." ”

According to Ah Cai, just after 12 o'clock in the night, when she passed by the living room, she happened to see Sheng Baiheng walking out, holding something in her right hand, and she didn't see that it was a knife. At that time, Sheng Xingchen had just come back, and he was standing in the courtyard outside the living room and bowing his head to play with his mobile phone, when Sheng Baiheng suddenly rushed over and stabbed the knife into Sheng Xingchen's body. In Ah Cai's exclamation, Sheng Baiheng pulled out the knife again, returned to the living room, and walked inside, while Sheng Xingchen fell to the ground.

Ah Cai was so frightened that the six gods were gone, and she shouted and rushed upstairs, waking up Sheng Changtian and Qiu Naping, who were already asleep, Qiu Naping was originally a surgeon, and she urgently stopped Sheng Xingchen's bleeding. After the ambulance came, Sheng Xingchen was taken to the private hospital where the Sheng family's personal doctor was.

Sheng Changtian followed him to the hospital, Qiu Naping's heart was not good and she couldn't stand the toss, Sheng Tianchang asked her to stay at home with Sheng Baiheng, watched him, and at the same time brought Yan Xinyi over to discuss what to do.

Yan Xinyi hurriedly rushed into the living room, Qiu Naping leaned on the sofa, her eyes slightly closed, Sheng Baiheng sat on another sofa, her head buried low, her fingers stuck deep in her messy hair, like a stump of a tree without moving.

Hearing the sound, Qiu Naping opened her eyes, and Sheng Baiheng slowly raised her head.

"Mom, go back to your room and rest, I'll talk to my eldest brother." Yan Xinyi knew that her mother was not in good health and needed to ensure rest, so it was not appropriate to toss in the middle of the night like this.

"Okay, you talk." Qiu Naping stood up, and Ah Cai came over to help her upstairs to rest.

Yan Xinyi sat down on the sofa next to Sheng Baiheng and said in a soft tone: "I have heard that you stabbed Xingchen, can you tell me what is going on?" ”

Sheng Baiheng slowly raised his head. "I don't remember, Ah Cai said that he saw me stabbing the third child with a knife, but I don't remember doing anything like that." He looked confused, "I remember going to bed at 11 o'clock last night." When I woke up, I was in the restaurant. ”

Yan Xinyi's heart seemed to have been hit by something, and there was a "bang" sound. "What were you doing in the restaurant at the time?" She asked.

"I'm standing in front of the knife holder, and on the knife holder, there's a blood-stained fruit knife." Sheng Baiheng replied.

"Is that where the fruit knife is usually placed?" Yan Xinyi asked again.

Sheng Baiheng nodded slightly, "Yes." ”

"You were covered in blood at the time, right?" Yan Xinyi looked at the thin shirt on his body, "You took off your coat?" ”

"The coat is in the restaurant, it's stained with blood, I don't know why there is so much blood." Sheng Baiheng held his head with his hand, "At first, I thought I was injured, and I checked my body in the mirror, but I didn't find any injuries. Later, I heard what Ah Cai said......"

"Have you had memory impairment before? Have you ever taken medicine or sleepwalked? Yan Xinyi continued to ask.

"No, never." Sheng Baiheng replied in the affirmative.

"You hate Xingchen, you hate him for strengthening your fiancée." Yan Xinyi changed the direction of the question, "This hatred is your motive for killing, right?" ”

"I hate him." Sheng Baiheng did not deny his hatred for Sheng Xingchen, "But I never thought of killing him." ”

Yan Xinyi stared at him tightly, "You don't have killing intent, do you?" ”

"Killing Intent......" Sheng Baiheng paused, "I should have had a momentary thought, the idea of killing him, but I won't really do it." ”

"Is it limited to imaginary killing intent?" Yan Xinyi guided.

Sheng Baiheng shook his head blankly, "I don't know what the hell is going on. ”
