Qiao Yan read a lot of things from Mo Yuqing's eyes, including regret, sadness, and infinite sorrow. She has not only admiration for the former detachment leader, but also admiration, not for subordinates to superiors, but for women's feelings for men. Qiao Yan knew in her heart, that Mr. Hai Haoyi was out of action for the time being.

"Forget it, don't mention these sad things." Mo Yuqing sniffed, "I've already answered your question, now it's time for me to ask you." ”

"What's the problem?" Qiao Yan was puzzled.

Mo Yuqing looked at Qiao Yan and thought about it for a long time. "What's going on with you and our new detachment leader?"

Qiao Yan looked even more confused. "What do you mean?"

"Don't pretend to be confused." Mo Yuqing raised her eyebrows, "I can see that he pays special attention to you, and you, in front of him, look very unnatural." ”

"No, you must have lost your eyes." Qiao Yan refused to admit it, but after thinking about it, Mo Yuqing also studied psychology, where could she hide it from her eyes, so she changed her words, "Whether he pays special attention to me, I didn't pay attention." If I'm in

It's unnatural in front of him, and that's because, I think this man ...... How to say it. ”

A thought popped into her head, and then without thinking about it, she reflected it through her words, "I suspect that he has a psychological problem, possibly caused by overdepression." ”

"What kind of repression are you referring to?" Mo Yuqing smiled mysteriously, "Don't you want to say that you suspect that he, like the criminal who killed Fang Hong, did not get an effective release from sex in real life." ”

Qiao Yan did have such suspicions in her subconscious, Wei Chihong's abnormal performance when he got along with her, the previous rumors about him, and Zhong Kai said that he couldn't face a woman's nakedness, all of which made her unable to help but have some associations, especially after he himself conducted a deep psychological analysis of Fang Hong's murderer.

Now once Mo Yuqing is broken, Qiao Yan can't stop the surging thoughts in her mind. "Wei Chihong...... Could it be that there is also sexual dysfunction, so there is some psychopathology? Qiao Yan boldly expressed her suspicions, her face was hot, but her body shivered slightly, "It's really scary to think about, could it be that he also has a strong tendency to sexual aggression, as long as there is a trigger, he will distort and explode?" ”

"Not really. But if that's the case, you have to be careful. After Mo Yuqing finished speaking, she suddenly burst out laughing.

Qiao Yan glared at her. "What's so funny."

Mo Yuqing couldn't stop laughing even more. However, when she glanced at the figure at the door, her face changed so much that she could no longer smile.

Qiao Yan followed Mo Yuqing's line of sight, and all the blood in her body rushed to her head, her hands and feet were cold, and her scalp was numb.

Yu Chihong stood there, like a stone statue, with closed lips that didn't even move.

"It's miserable." Mo Yuqing lowered her voice and said in Qiao Yan's ear in a panic, "He probably heard what we just said." ”

Qiao Yan is already six gods and no master, talking about the boss behind his back, it is still such an unbearable topic, the most important thing is that he listened to it, and there is nothing more tragic than this.

Mo Yuqing saw that Qiao Yan seemed to be frightened, so she could only stand up by herself and accompany her smiling face. "Hello detachment leader, what's the matter?"

Yu Chihong finally changed his standing posture, as if a stone statue had been lit by magic suddenly revived.

"I'm looking for Qiao Yan for something." His voice was unwavering, and he couldn't hear any emotion.

Qiao Yan was slow to move because of her weak heart, slowly withdrew her stretched legs, and then slowly stood up, like a slow motion in a movie, moving to Yu Chihong step by step.

"You're looking for me...... What's up? She didn't dare to look at him, and her voice trembled a little.

"The surveillance camera at the intersection that the police in the area said was broken." Wei Chihong opened his mouth to talk about the case, "Now we can only expand the scope to other intersections around, but in this way, the amount of work is too large." Therefore, I hope that you can give a more accurate portrait of the crime and narrow the scope of the investigation as much as possible. ”

Qiao Yan looked at him carefully, calm and indifferent. She had a hint of luck, maybe he didn't hear the conversation between her and Mo Yuqing? She steadied herself, trying to calm her fluctuating emotions. "Is there any more information you can give us?"

"If you come with me to Cao Chongshan now, there should be a new harvest." Wei Chihong looked confident.

Qiao Yan had no choice but to obey orders. Before leaving, Mo Yuqing quietly pulled the corner of her clothes. Qiao Yan turned around, and Mo Yuqing squeezed her eyes. "Take care of yourself."

Qiao Yan's heart panicked again, and when she took the elevator, she asked suspiciously with a cautious look: "Did you hear what I said to Mo Yuqing just now?" ”

"Nope." Wei Chihong replied simply, and looked at her suspiciously, "Did you say bad things about me, afraid that I would hear it?" ”

Qiao Yan pretended to be calm. "Of course not."

Wei Chihong did not continue to dwell on this topic, and Qiao Yan also breathed a sigh of relief.

Cao Chongshan's first sentence when he saw Wei Chihong was to complain as usual. "Lord Wei Chi, you are really not interesting. I finally had a chance to take a vacation, and you made me miserable again. ”

Wei Chihong took his words as wind in his ears. "The results I wanted, are they out?"

"Hey, are you listening to me?" Cao Chongshan's eldest son was unhappy.

"Hear me." Wei Chihong didn't care, "When this case is over, don't you just make up for the vacation." ”

Cao Chongshan snorted heavily. "To put it mildly, I promised my wife to take her out to play, but I broke my promise, and you caused me to be scolded by her."

Yu Chihong mocked leisurely. "What else can you do besides talking about your wife."

Cao Chongshan trembled his two eight-character eyebrows. "Anyway, you have to make amends, so let's see for yourself."

"Okay," Wei Chihong was a little impatient, "When this case is over, if you have any requirements, you just have to mention it." ”

Cao Chongshan shrugged his nose and reluctantly got to the point. "From the wounds of the remains, trace amounts of bismuth and indium were detected."

"What is it?" Qiao Yan didn't understand.

"It's metal." Yu Chihong pondered and said, "It is speculated that the murder weapon is a sharp knife, but usually knives do not use this element. The murder weapon has never been found, which is strange. ”

"When did the surveillance camera at the intersection break?" Qiao Yan asked.

Wei Chihong replied that it was the day before the murder. "This shows that the prisoner is very familiar with the area and should have driven past that intersection often. In addition, he knew very well the residence of a street girl, and they must have been in contact more than once. According to the results of the investigation, Fang

Near the house where Red lives, some residents have seen her accosting a passing man on the street at night. The solicitation location of street women is generally near the prostitution den, accosting the man first, and then bringing the person over. In this way, the prisoner and Fang Hong had the opportunity to contact at night, and the location was near the rental house.

Judging from the prisoner's familiarity with the area, either he lived nearby or worked nearby. It is more likely that the place of work is nearby. Let people check if there are any units such as metal products processing factories nearby. ”

The investigation soon led to the results of a Red Star hardware machinery processing factory near the rental house.

When Qiao Yan returned to the office, Zeng Jinling and Wan Xing also came to work, and the four of them immediately engaged in discussion.

"The prisoner is working in metal fabrication?" Mo Yuqing asked.

"Wei Chihong seems to think so." Qiao Yan was still a little confused, she didn't know anything about metal elements at all.

The other three also had no study of metallic elements.

"Metallic elements are not part of our scope." Zeng Jinling distributed a stack of materials to everyone, "This is the case material that I have reorganized, let's take a closer look and then make further analysis." ”

Fang Hong's weight is close to 120 pounds. Based on his footprints, Cao Chongshan speculated that the prisoner weighed 140 kilograms and was about 1.75 meters tall. After deducting Fang Hong's weight, the prisoner's actual weight is almost 160 pounds, and his height is about 1.75 meters, which is a man with a fat body. ”

After reading the materials, Qiao Yan said, "The identification results show that the pace is very chaotic, and the distance between the footprints is short and uneven. There is also a large paragraph next to it, who wrote it? ”

Zeng Jinling said that it was Wei Chihong's analysis.

Qiao Yan stared at it, his words were really beautiful, his pen was like flowing water, and the pen was vigorous and powerful. The content of the note is: This shows that the criminal may be exhausted, such a height and weight, carrying a person of 120 pounds, if it is a young man in good health, will not be exhausted. In addition, young people tend to have large footprints, large strides, and even distances between footprints and walk in a straight line. Middle-aged people walk steadily and slowly, and the distance between footprints becomes shorter. The stride of older people becomes shorter. This person's pace, even if he takes into account personal factors, is by no means younger, at least over 35 years old. ”

"And about the sexual dysfunction of the prisoners." Zeng Jinling added, "The onset of male sexual dysfunction is directly related to age, and the older you are, the more likely it is to cause sexual dysfunction. In fact, this is inseparable from the physiological state and psychological evolution of men......"

Mo Yuqing couldn't help but burst out laughing, disturbing Zeng Jinling's train of thought.

"What are you laughing at?" Zeng Jinling looked at her strangely.

Wan Xing had been lazily sinking into his chair, looking like he didn't care about himself, and his eyes drifted towards Mo Yuqing at this moment.

Only Qiao Yan understood why Mo Yuqing was laughing, she was worried that Mo Yuqing would tell the trouble, so she hurriedly said: "What's so funny about this, you have to look at the problem with a professional eye." Professor Tsang continued, ignoring her. ”

"Yes, Professor Zeng continued." Mo Yuqing held back a smile and pretended to be serious.
