This fixed blind date activity actually made Qin Yi a little uneasy, because saying too much might expose something. After all, Xia Yuxin is a very smart girl, and she is very good at paying attention to details, and many of them are details that he has not paid attention to. However, Qin Yi was still very confident in his mouth, and so many agents from other countries did not take out any information from his mouth.

What's more, Qin Yi does have a little interest in Xia Yuxin's past, but it's not those ex-boyfriends or whether they are virgins or anything like that, after all, he has had relationships with many women, so what qualifications does he have to ask the other party to be the first time? He needs to understand her character through the other party's past.

Because as a stranger, Qin Yi can evaluate a person objectively and fairly, but it is difficult not to be prejudiced against people he is familiar with. This is the same for the person you hate and for the person you like, it is a fatal wound for a person who is engaged in psychological profiling, and you must not bring personal emotions when you write a profile.

If a suspect is disgusted by something he or she has done, such as having a criminal record or a violent tendency, and is prejudiced to think that the other party is the murderer, and thus forcibly attaches a lot of profiles to the suspect, it is likely that the real murderer will go unpunished.

However, I have to say that the time with Xia Yuxin is always very happy.

"Then ......" Xia Yuxin thought for a while, tilted her head and smiled: "You told me about the case you remember the most last time, tell me one this time, the case you think is the most regrettable, right?"

"You know you're forcing me to recall those unhappy pasts, right?" Qin Yi asked with a smile.

"Yes, but please. Xia Yuxin folded her hands and pleaded, as cute as a cat, "In exchange, I will tell you anything you ask me, including my favorite underwear style and color." ”

"That's an exaggeration. Qin Yi smiled, "Actually, it's not a big deal, those wounds buried in the bottom of my heart are not really healed, on the contrary, talking and sharing with others can vent this negative feeling, which is of great help to psychological trauma." You're very clever about it, I've used a similar method to communicate with my patients before. ”

"Really? Let's talk about it. Xia Yuxin said with a sweet smile.

"Hmm...... Is it the most regrettable?" Qin Yi held his chin and groaned for a moment, then nodded, "Once, there was a county town in Arizona in the United States. You know, the county is far from the city, the town is too small and the population is too small, etc., which makes these serial killers more likely to appear. ”

Xia Yuxin took a sip of coffee, then looked at him intently with her chin in her hands, and nodded with a smile. Qin Yi continued: "At that time, there were several serial killings in this town. There are obvious commonalities that indicate serial killings, such as the victims are fathers and sons or fathers of fathers and daughters, and none of the children are injured. ”

"Well......" Xia Yuxin looked at him with a smile like a little girl listening to her father's story.

In addition, from the modus operandi, it can be inferred that the perpetrator was a serving or retired member of the army. Because the way to kill the victim was a forehand pivot, a knife wound was also a wound left by a saber in the army. Qin Yi explained.

"Later, we asked the child about the man's general situation, height and weight, but his appearance was not clear. However, from the conversations between the assailant and the children, and the scene of the crime at the time, I deduced that the man had severe post-war traumatic sequelae. Qin Yi said this, shook his head and sighed, "He is a veteran who participated in the Iraq War. ”

"How did you deduce this?" Xia Yuxin asked curiously.

"The conversation he had with the children was to tell them to run away, and he killed them because he felt they were enemies. But at the same time, he told the children to 'run away' instead of letting them 'go home'. Qin Yi explained.

Speaking of this, Qin Yi smiled: "Then let's take a look at this line." 'Run' and 'go home' are two very different phrases in English, so why not let them go home? Because he knows that their home has been destroyed. ”

Immediately, Qin Yi stretched out his index finger and drew a simple distribution map on the table: "At that time, the environment of several crime scenes was basically similar. There are abandoned old houses that are about to be demolished, and there are construction sites in progress. ”

Saying that, Qin Yi smiled: "Here, I have to explain it to you." Post-war traumatic sequelae, or PTSD for short, has a high incidence among soldiers who have participated in war. Ordinary people can't kill people normally, especially strangers, and they are likely to feel guilty after killing enemies, especially after killing civilians and children. This guilt can lead to nightmares that can lead to insomnia, and in the long run, severe hallucinations and psychotic anxiety. ”

Xia Yuxin nodded abruptly, and Qin Yi continued: "PTSD is a kind of psychological trauma that is easily affected by the environment, and the noise from the construction site is likely to be mistaken by the patient for the sound of gunfire or bombing, which causes the patient to suddenly become ill and think that he is in the middle of the battlefield. That would explain why he killed the adults and let the children escape. ”

"So, this murderer is actually a good person?" Xia Yuxin asked worriedly.

"Who can tell the difference between good and bad. Qin Yi smiled, "Good guy, indeed, the murderer is a war hero, he is a sniper, and he was awarded the Medal of Honor for saving many teammates in the Iraq War. ”

However, Qin Yi shrugged his shoulders again: "But, bad guys? Those innocent fathers were indeed killed by him, and for others, he is a murderer, and this will not change. ”

"Then, how did you find him later?" Xia Yuxin hurriedly asked.

"You see, he's a soldier who thinks he's on the battlefield and surrounded by enemies, and he's isolated. In this case, he will find a way to seek help. Qin Yi explained, "So we searched the radios of various bands, and sure enough, we found his distress signal, and managed to get one of his comrades to contact him and notify him of the evacuation point." ”

"Was he saved in the end?" Xia Yuxin asked again, Qin Yi smiled and didn't say anything, but Xia Yuxin already knew the answer: "No...... Otherwise, it won't be your most regrettable case. But why? Isn't it already ......?"

Qin Yi sighed: "At that time, he had successfully arrived at the evacuation point, and the local police still placed snipers just in case, but in order not to let strangers alarm him, only his comrades were waiting for him at the retreat site." Just as the man was retreating, a civilian man who was running at night happened to pass by and broke into the retreat because he didn't know the details. ”

Saying that, Qin Yi shrugged his shoulders: "At that time, the suspect had a weapon in his hand and would pose a threat to civilians, so the sniper fired. The sniper's judgment is actually fine, it can only be said that it is destiny...... Can you know what it felt like when his wife and son arrived? No one was a winner, just a lot of tragedies. If you have to say it......"

Qin Yi shook his head: "The culprit should be the war." That's why we should oppose war and support peace. ”

"Hmm......" Xia Yuxin pursed her lips and nodded with a smile, "I like your idea very much." ”

"Actually, I don't think talking about this kind of thing will help our blind date process, I always think it will make the process very ...... Heaviness. Qin Yi smiled bitterly, "It's very ruinous atmosphere, don't you think?"

"I don't think I'm getting to know you now. If I could have a formal relationship, of course I wouldn't ask such a heavy topic during the date, and even if I did, I would have found a way to make the atmosphere more relaxed. Xia Yuxin explained with a smile, and then groaned, "For example, ......"

After thinking about it, Xia Yuxin smiled: "Do you want to know the color of my underwear today?"

"Poof......" Qin Yi almost squirted out the coffee in his mouth.

"Look, this makes the atmosphere a little more relaxed, right?" Xia Yuxin winked at Qin Yi and smiled.

"I can't see it...... Yuxin, you are a lot bolder than you imagined. Qin Yi wiped his mouth and said helplessly, Xia Yuxin held her chin and asked with a sweet smile: "Then, do you want to know, or do you want to know something else?"

Qin Yi thought for a moment and asked again, "Then tell me about the best love experience in your memory." ”

Xia Yuxin frowned a little distressed: "This ......"

"Don't rush, just think slowly. Qin Yi said with a smile, Xia Yuxin pursed his mouth: "Actually, there is nothing to say." I'm not afraid that Xiaoyi will laugh at me, I haven't been in love once yet. At most, there are a few crushes. ”

"Are you in your twenties?" Qin Yi asked with interest, Xia Yuxin squinted at him with some dissatisfaction: "It's twenty-five into twenty-six, if you have to count it, you should be twenty-seven, right?"

"No, I'm just curious why. Qin Yi held his chin and smiled.

"Guess what?" Xia Yuxin asked with a smile while holding her chin, Qin Yi thought for a while: "Generally speaking, girls don't fall in love at this age, either because of problems with their sexual orientation, or because their parents' marriage has been unsatisfactory, such as one of the parties cheating or divorced, causing the child to have a psychological shadow because of the fear of repeating the mistakes of the past......"

Xia Yuxin smiled bitterly: "Xiaoyi is really amazing...... There is a part. My parents divorced when I was a kid because my mother ......"

Saying that, Xia Yuxin sighed: "I don't know if my mother is doing the right thing." She's the kind of ...... A very emotional person must be with the person he loves. After about ten years of marriage to my father, the passion between the two of them subsided, and my mother found a man who could rekindle the flame of her love, so she resolutely decided to divorce and ...... with that man"

Xia Yuxin shook her head: "I don't know if she did it right." Yes, she betrayed her promise of neutrality in her marriage and chose to abandon her husband and children;

Xia Yuxin sighed: "So, until now, I have been very careful when choosing a boyfriend. Even if a few men have a crush on someone and have a crush, I still don't make a decision to date each other on the spur of the moment, but secretly observe. When I was a student, I never considered falling in love, although ......"

Speaking of this, Xia Yuxin smiled: "There have been so many people who have agreed to live for life, and they have agreed to fall in love after going to college together, because I think that true love is not in the morning and twilight? ”

Xia Yuxin shook her head helplessly: "I just want to fall in love only once in my life, get married only once, and be owned by only one person." So I always tell them, if you can get into a university with me, and then graduate together and stay in the same place, I'll consider dating them. But ......"

Xia Yuxin smiled a little tiredly: "In the end, no one can pass the test." That's when I realized that time is the worst enemy of love. Either they can't stand the temptation to be with other women who are willing to associate with them, or they choose to give up because of their physical needs. ”

"I see...... Qin Yi held his chin and smiled, this was actually the first time he really understood a certain part of Xia Yuxin. Usually Xia Yuxin behaves perfectly, but that's just an illusion, people can always show their perfect self in front of outsiders, but only in front of the person they really like will show their fragile or dark side.

And Xia Yuxin is such a person, before this, Qin Yi only knew that she liked food, and her personality was gentle and a little dark, but in fact, Qin Yi didn't know the real her, but only had some rough guesses. Now it feels so much better.

"Hmm......" Qin Yi pondered for a while and replied with a smile: "I think this way of exchanging secrets is not bad." ”

"Really?" Xia Yuxin held her chin and tilted her head to look at him, her expression was a little naughty, very cute.

"Of course, let's exchange secrets together next time. Qin Yi nodded and said.
