Outside the dissection room, in the corridor, Zhu Xumei covered her mouth with one hand, leaned against the wall with one hand, and leaned against the wall of Bai Huahua, her face was very pale, obviously, she saw such a bloody scene just now, which brought her a very big visual impact, Zhu Xumei's body shook a few times, and then slowly squatted down.

Zhu Xumei is not a native of S City, she only came to S City yesterday, and she is very unaccustomed to everything in S City, and she did not choose to eat breakfast in the morning, not that she was not hungry, but that she was not used to eating, so she did not eat, but now it seems that not eating breakfast is a good thing, at least when she felt her stomach churning, she did not vomit everywhere in the dissection room, otherwise, with Ye Xuefei's temper, it would not be as simple as simply driving Xu Lang and her out.

Zhu Xumei squatted on the ground for a while, and finally suppressed the desire to turn over the river and the sea, almost vomiting, she originally thought that Xu Lang would come over to comfort her a few words, at least a few words of comfort, but she waited for a long time, did not hear Xu Lang say a word, Zhu Xumei was a little disappointed, and even a little complaining, she raised her head, turned her head to look at Xu Lang, and found that Xu Lang was holding a plaster model in his hand, leaning against the wall, Xu Lang's eyes have been staring at the plaster model, looking over and over, which makes Zhu Xumei, who is in urgent need of comfort, Growing dissatisfaction.

Xu Lang looked at the plaster model in his hand, the blade is very long, about more than 30 centimeters, the blade presents a slightly curved arc, very similar to the Nepalese saber, their appearance is very similar, but not very similar, the knife of the model, in addition to the knife edge that should be, there is also a bleeding groove on the knife body, and the back of the knife is not like other knives at a glance, nothing, there are dense serrations on the back of this knife, a bit like the appearance of a saw.

Xu Lang had never seen a similar knife on the market, and obviously, this murder weapon was made by the murderer.

"Hey"

Just when Xu Lang was completely focused on the knife, Zhu Xumei didn't know when to stand up, leaning on the wall with one hand, and looking at Xu Lang with a not very good face.

"Huh?!"

When Xu Lang heard this, he raised his head suspiciously, looked at Zhu Xumei who was standing not far away and asked, "What's wrong?" Something? ”

"Buy me a bottle of water." Zhu Xumei said angrily.

Xu Lang glanced at Zhu Xumei, ignored her, and continued to fiddle with the model in his hand.

"Hey"

Seeing that Xu Lang ignored her, Zhu Xumei was already angry, and she was scolded by Ye Xuefei just now, and now that Xu Lang treats her so coldly, she is becoming more and more dissatisfied.

"Hey"

Zhu Xumei shouted again.

Xu Lang put away the model in his hand, raised his head, glanced at Zhu Xumei, and said lightly: "What are you feeding?" ”

"Buy me a bottle of water, I'm uncomfortable." Zhu Xumei raised his neck, squinted at Xu Lang and said.

Xu Lang held the plaster model in his left hand, and walked towards Zhu Xumei, who was standing against the wall, with an expressionless face, and when he came to Zhu Xumei, Xu Lang raised his right hand and waved towards Zhu Xumei.

"Ahh What are you doing? Hitting someone is a violation of discipline, I warn you not to mess around, ah! ”

Seeing Xu Lang's cold expression and the waving right hand, Zhu Xumei, who was still pretending to be calm, hurriedly closed her eyes and shouted loudly, she hoped to attract the colleagues around her.

Zhu Xumei waited for a long time, did not wait for the expected slap, she had some doubts in her heart, her eyes opened a gap slightly, and she saw a face close at hand, a pair of dark and deep eyes, looking at her without any emotion, Zhu Xumei's head turned slightly to avoid Xu Lang's slap, slowly opened her eyes, and then saw Xu Lang's right hand supporting the wall, Xu Lang's right hand was only a few centimeters away from her cheek, Zhu Xumei breathed a sigh of relief at the same time, and the sense of humiliation burst out from the depths of her heart, Then there was deep anger, she stared at Xu Lang with a pair of big eyes, and shouted, "What are you doing? ”

Xu Lang's already not very good face heard Zhu Xumei scolding, his brows wrinkled subconsciously, Xu Lang raised his right hand propped up on the wall, stretched out his hand, pinched Zhu Xumei's smooth chin, and said in a cold tone: "First, I don't call him, I have a name, my name is Xu Lang, you can call me Xu Lang, you can also call me Brother Lang, or call me Advisor Xu; Second, this is the second criminal investigation team of the Public Security Bureau of S City, where you work, not a school, not your home, no one has a reason to get used to you, if you feel unhappy, you can go home, or call your father, who is the deputy director, to complain; Third, we are all adults, we are all busy, no one has time to play with you, coax you to be happy, capable, willing to do it, you stay, if you can't do it, don't want to do it, just leave, or I will ask Ning Yanran to arrange an easy job for you, so as not to be an eyesore here. ”

After saying these words, Xu Lang let go of the hand that was pinching Zhu Xumei's chin, he stood up straight, turned around and walked outside, without looking at Zhu Xumei.

The movement here just now attracted the attention of many colleagues, they thought that something was going on here, but when they saw that it was Xu Lang and Zhu Xumei standing there, after hearing what Xu Lang said, they left one after another, this is Xu Lang and Zhu Xumei's private matter, they can't care about it, it's not something they worry about, there is still a lot of work in hand, they don't have time to care about this.

Zhu Xumei was frightened by Xu Lang's ruthless expression and attitude, tears suddenly gathered in her eyes, flowing down her cheeks, she looked at Xu Lang's distant back, Zhu Xumei felt extremely aggrieved, before, whether at school or at home, everyone revolved around her, her mother never said a word to her, and although her father usually looked strict, he rarely criticized him, as for school, because she had good grades and was beautiful, many boys revolved around her, Buy her gifts, meet all her requirements, and coax her to be happy, but today is her second day at work, and she was treated so rudely by Xu Lang.

Xu Lang, who was about to leave the corridor of the dissection room, suddenly stopped, turned around, looked at Zhu Xumei, who was still standing in place crying alone, frowned, and said: "I'm going to the scene soon, if you don't go, follow if you want to go, or if you don't go, get out of here, I don't have time to play with you." ”

After saying this, Xu Lang left without looking back.

Zhu Xumei stood in place and hesitated, and finally chose to follow Xu Lang to investigate the scene.

After Zhu Xumei left, Ning Yanran, who was standing at the other end of the corridor, walked out slowly, she came to the door of the dissection room, looked at Zhu Xumei's distant back, shook her head, and muttered to herself: "Hey, the wicked still need the wicked to grind." ”

"Xu Lang helped you solve such a hot potato, and you are talking about him behind your back?"

The door of the dissection room was suddenly opened from the inside, Ye Xuefei put her hands in her pockets, leaned against the door frame, glanced at Ning Yanran, and then looked at the place where Xu Lang and Zhu Xumei disappeared.

Hearing Ye Xuefei say this, Ning Yanran smiled bitterly, and then said: "To be honest, Xu Lang really helped me a lot, when I learned about the girl's background, I really didn't know how to arrange her, now it's okay, since Xu Lang is willing to help, I also have a lot of worries." ”

Ye Xuefei glanced at Ning Yanran deeply, didn't say anything, turned around and walked into the dissection room, and closed the door of the dissection room casually, Ning Yanran didn't stay here for long, turned around and left, she was still reluctant to enter the dissection room.

When Zhu Xumei came out of the autopsy room, he came to the parking lot and saw a police car lit up, and Xu Lang sat in the co-pilot.

When Zhu Xumei came, the car had already started and was ready to leave, Zhu Xumei hurriedly ran over, stopped the police car, and when the car stopped, she opened the back door, sat in, and then closed the door heavily.

It was Li Lei who was driving, and after he saw this scene, he just shook his head secretly, didn't say anything, and started the car directly and went to the scene of the incident.

On the way to the scene, Xu Lang has been playing with the plaster model, without saying a word, although Zhu Xumei chose to keep up with Xu Lang, but her face is very ugly, sitting in the back row, her eyes are staring at the back of Xu Lang's head without blinking, her mouth is bulging, obviously, she is still angry, Li Lei saw this scene from the rearview mirror, couldn't help laughing, and couldn't help but sigh in her heart, Zhu Xumei is really a newborn calf who is not afraid of tigers, she met Xu Lang I don't know whether she is lucky, or she is unlucky, but, These are Li Lei's own thoughts, and it is impossible to say them.

It had been raining outside, and there were few pedestrians on the road, Li Lei drove cautiously, and out of the corner of his eye, he saw the plaster model in Xu Lang's hand, so he asked: "Brother Lang, is this the simulated murder weapon?" ”

Xu Lang nodded and said, "Yes, take a look and see if you can see something." ”

"Cut"

Zhu Xumei, who was sitting in the back row, pursed his lips disdainfully.

The car stopped at a traffic light intersection, Li Lei took the plaster model in Xu Lang's hand, looked at it twice, and returned the model to Xu Lang, when the green light was on, he started the car, and said while driving: "This knife looks a bit like a saber, but it is not the same as a saber." ”

"What's the difference?" Xu Lang asked.

"The overall blade is longer than the ordinary saber, shorter than our common butcher knife, and there is a bloodletting groove on the knife body, and the bloodletting groove is very deep.

After Li Lei finished speaking, he looked at Xu Lang.

Xu Lang nodded and said, "What you said, I noticed it a long time ago when I saw the model, this knife was tailor-made by the murderer to kill people, so what can these mean?" ”

Hearing Xu Lang ask this, Li Lei couldn't help but smile dumbly and said, "Brother Lang, are you testing me?" ”

"Sort of." Xu Lang said noncommittally.

"Cut, if you can't think of it, you can fool others, it's really shameless." Zhu Xumei sat in the back row and muttered quietly, although her voice was small, but the car was so big, there were three people sitting in the car, and what she said naturally came to the ears of Xu Lang and Li Lei.

Xu Lang didn't have any change in expression, Li Lei glanced at Zhu Xumei from the rearview mirror, then turned his head and glanced at Xu Lang, seeing that Xu Lang didn't say anything, he said: "According to the model of this murder weapon, I have a few guesses. ”

"Tell me about it." Xu Lang said.

Zhu Xumei saw that Li Lei and Xu Lang didn't care about herself, she suddenly became angry, snorted heavily, and then turned her head and looked out the window.

"First, the guy who caused nine homicides in S City in a row is likely to be a professional murderer, and this, judging from the wounds of the nine taxi drivers he killed, they were all killed with a single knife, and the means were clean and neat, and it can be seen that there is no mud and water."

"Second, the murderer may be a retired soldier, or someone who has served in the armed police and special police departments, otherwise, he would not know so much about cold weapons such as sabers and transform them."

After listening to Li Lei's analysis, Xu Lang nodded, then turned his head, looked at Li Lei and asked, "It's gone?" ”

Li Lei nodded and said, "It's gone." ”

Xu Lang didn't say anything, turned his head, and rubbed his chin.

Li Lei asked curiously, "Brother Lang, what do you see?" ”

"He can see a fart, except for being a murderer, I don't think he has any skills." Zhu Xumei, who was sitting in the back row, interjected.

Zhu Xumei interjected again and again, sneering at Xu Lang, Li Lei didn't care much at first, now he looked at Xu Lang, and then looked at Zhu Xumei who pretended to look at the scenery outside the window from the rearview mirror, he was a little curious, Xu Lang What happened to this newcomer, however, curiosity is curiosity, Li Lei is not the kind of person who is particularly gossipy, he will not ask anything casually.

Xu Lang picked up the plaster model and said to Li Lei: "Didn't you find out that this is a left-handed knife?" ”

Hearing Xu Lang say this, Li Lei was stunned for a moment, he turned his head, looked at the plaster model a few times, and still didn't see anything, he shook his head and said, "Isn't it a knife, what is the left hand and the right hand." ”

Xu Lang pointed to the handle of the plaster model and said: "You are right, in fact, no matter what kind of knife, when it is built, it is built according to the right-hand knife, after all, most people are right-handed, and our common knives are like this, but you look at the handle of this knife, it is obviously not the same as our common knives." ”

Li Lei turned his head again and looked at the place where Xu Lang's finger pointed, only to find that indeed, the position of the handle is indeed not the same as the ordinary handle, the handle design of the general knife is the thumb inside, the four fingers are outside, and the lines on the handle are the same, but the handle of this knife is the opposite, if it is not left-handed, or someone who has a certain understanding of the left-handed knife, it is impossible to notice this small detail, thinking of this, Li Lei nodded, and couldn't help but praise: "Brother Lang, there is really you, this has been discovered by you." ”

Xu Lang smiled and shook his head.

"Sycophants." Zhu Xumei interjected in the back row again.

Li Lei, who was driving, blushed, although half of his compliment to Xu Lang just now was from the heart, but some of them were indeed suspected of being sycophants.

Xu Lang didn't care about this, he looked at the front of the car and said: "This shows that the murderer is a left-handed person who is good at using a left-handed knife." ”

"And then? What does this mean? Li Lei asked puzzled.

"This shows that the murderer of nine taxi drivers in a row is not Xie Yongjun." Xu Lang said lightly.

"Why?" Li Lei became more and more puzzled.

"Arbitrary." Zhu Xumei was also aroused by Xu Lang's words, she didn't pretend to look out the window, but turned her head and looked at the back of Xu Lang's head.

Xu Lang lit a cigarette, spit out a puff of smoke rings, and said slowly: "Because I know Xie Yongjun." ”

"What?"

"Click"

The reason given by Xu Lang frightened Li Lei, he slammed on the brakes, and the car stopped on the road all of a sudden, with the inertia of the car, the bodies of the three people rushed forward, Xu Lang and Li Lei were wearing seat belts, and when the body was rushing forward, they were pulled back by the seat belt, and Zhu Xumei sat in the back row, not wearing a seat belt, her head hit the back of the co-pilot's seat at once, and her smooth forehead was suddenly hit red.

"How do you drive? Oops, it hurts me. Zhu Xumei straightened up and grumbled while rubbing his forehead.

Li Lei was not in the mood to pay attention to Zhu Xumei at this time, but turned his head, looked at Xu Lang's side face and asked, "Brother Lang, how do you know Xie Yongjun?" I remember that Xie Yongjun was imprisoned for intentional injury five years ago, and at that time, you had not yet become a police officer, how could you possibly know each other? ”

Xu Lang took a puff of his cigarette fiercely, then spit out a thick smoke ring, and said slowly: "I sent it in with my own hands." ”

"What?" Li Lei was shocked again.

Li Lei looked at Xu Lang's expression, shook his head like a rattle, and said, "This is impossible, Brother Lang, you are kidding me." ”

Xu Lang turned his head, looked at Li Lei's eyes, and said: "What am I teasing you for, he was really sent in by me five years ago, but not as a policeman, but as an undercover agent." ”

Speaking of this, a self-deprecating expression appeared on Xu Lang's face.

Hearing the word undercover, Li Lei immediately understood, and he figured out many things, no wonder when he inquired about Xie Yongjun's archives before, what crimes did Xie Yongjun commit, who was arrested in, there were not too many records on the archives, they were all brushed aside, at first, they were still very confused, but now that they think about it, they understand that what they see is not a complete case file, but a simplified file.

Although he figured it out, Li Lei still didn't understand something, he looked at Xu Lang and asked, "But, what does this mean?" ”

Xu Lang shook his head and said, "I don't know, but I'm sure that Xie Yongjun is in danger now, and if we can't find him as soon as possible, we will die." ”

Li Lei looked at Xu Lang's side face and found that Xu Lang didn't seem to be joking, he took a few deep breaths, restarted the car, and accelerated towards the scene of the crime.

Zhu Xumei, who was sitting in the back row, heard the conversation between the two people, and was completely confused, she didn't understand, what was the relationship between Xu Lang and Xie Yongjun's acquaintance and solving the case, she didn't understand, but Li Lei understood.
