"You mean a middle-aged uncle" "There are men, uncles are rare, are you mistaken?"
"No, they're all young, but didn't Sister Chen mention that there have been uncle customers before.
In a nail salon called "Quewu", the young nail technicians and girls were aroused by Wu Duan's question, and gathered around the two of them to discuss with each other.
As it turned out, waking up early in the morning was the right decision.
At this moment, most of the nail salons have just opened, and the customers have not yet entered the door, and the nail technicians are still in a lazy and leisurely state, cleaning slowly and tidying up the tables.
So they're willing to talk to people.
Of course, Yan Sixian privately thinks that the nail technicians are so active, which has a lot to do with the appearance of the two.
Wu Duan had already started to ask.
"What are you talking about Sister Chen?"
"Our boss, didn't you ask the guests in June and July last year, the boss knows best, we don't know, we" The girl who answered looked around at the sisters around her, and after confirming it, she said, "We almost all came to the store after that, except for Sister Ya." ” The girl who was called Sister Ya was wearing heavy makeup, but even so, she still couldn't cover her dark circles.
She yawned a lot from just now, and the nightlife was very rich.
Seemingly dissatisfied with being named, she first glared at the girl who called her, and then replied: "Yes, I have seen a few men come to the store to get their nails done, but after so long, who can say whether there is an uncle or not." ” This is a real problem.
Wu Duan asked unrelentingly: "What about the members, if they become members?"
The girls shook their heads.
"Men rarely have members, and there are only a dozen or so male members in our store, maybe less than 10, all of them are quite young."
"That's it, we must know if there is an uncle."
The girls not only talked, but also called up the membership information in the store from the computer.
"That's all, not a single screen, or you take a photo" Wu Duan couldn't ask for it.
When Wu Duan was taking pictures, a girl asked Yan Sixian about the specific place of work, and wanted to add WeChat, saying that she had clues to report to the police at any time.
Yan Sixian kindly added them one by one, ignoring the girls' excuses.
In this way, the two visited dozens of nail salons in the morning, recording more than 100 male member information, and Li Zhixuan, the office clerk who cooperated with them, constantly screened the identity information of these men and excluded them one by one.
Yan Sixian also has a lot of personal gains, such as adding the WeChat of more than a dozen young and beautiful nail technicians.
At lunchtime, both of them were holding their mobile phones, and Wu Duan was looking at the map.
"We've all been to nail salons within a three-kilometer radius, but I really didn't expect nail salons to be so densely distributed in Mexico."
Seeing that Yan Sixian didn't answer, Wu Duan glanced at his mobile phone and found that he was chatting happily with the nail technicians he had just added.
"Is there a catch?"
Wu Duan asked.
"Not yet."
Yan Sixian put down his mobile phone, began to suck the noodles in the bowl, stuffed three mouthfuls of noodles into his mouth, puffed out his cheeks, and said vaguely: "But who knows which tree blooms?"
Regarding Yan Sixian's Qingqi thinking and attempts to cross the line, Wu Duan was no longer able to govern it, and he continued to talk about his own opinions.
"I feel that it can't go on like this, the nail industry has a fast turnover of personnel, and there has been an information gap 8 months ago, and it is difficult to inquire."
Thinking that in addition to his own and Yan Sixian, there were also four criminal investigation teams and more than 50 manpower in this matter, Wu Duan was extremely heartbroken.
"Then you have to go through a sieve, there is too little information, and you can't let go of the slightest sign."
Yan Sixian said: "A finger, a piece of meat, to rely on such a small number of things to determine the source of the corpse, this time everyone has to shed their skin." ” "Every time I get to this situation, I can't help but think that if only there could be a smarter way."
Wu Duan sighed.
"I think it's good to be an official now."
Yan Sixian said suddenly.
Wu Duandu gave him a surprised look.
"For example, if you don't want to visit, at least you can go back to watch the surveillance, and others don't have this privilege.
You say, some people are desperate to climb up, in addition to money, is it still for this bit of freedom?"
"There are some people I don't know, I just know that you definitely want to go back and watch the surveillance."
"You're so smart, how else you could be the captain."
Wu Duan's face was cold, "Don't pat yourself on the back." ” But in fact, the sycophants still played a role, and after eating, Wu Duan decided to return to the city bureau.
In the visit and investigation team of more than 50 people, the two of them are indeed dispensable.
Back at the city bureau, Yan Sixian went headlong into the graphic investigation office.

Wu Duan knew that he didn't have the poisonous eyes of Yan Sixian in terms of looking at the surveillance, so he went to the autopsy room.
In the autopsy room, Mink Fang was stunned at the slices of meat and a report sheet.
Coincidentally, when Wu Duan entered the door, she happened to swallow saliva on the meat slices.
"Holding the grass" Wu Duan was shocked by this picture and took three steps back, "You, you, you iron tooth bronze tooth Hannibal" Mink Fang simply licked her lips and said with pity: "It's a pity that it's missing." ” After fighting for two sentences, Mink Fang knew that the case had encountered a bottleneck, and Wu Duan was not easy to ask, so he took the initiative to say: "A small problem was found in the re-inspection results." ” "Tell me about it."
"I detected trace amounts of potassium permanganate residue on the side of the meat slice."
"Potassium permanganate," Wu Duan's gloved fingers rubbed against the edge of the corpse bed.
"Did you think of anything?"
said Mink.
"I have that thing at home, my mother raises chickens, disinfects chicken cages, and can generally buy pesticides and feed distribution points in the countryside.
In addition to disinfecting the chicken coop, my mom also wiped the refrigerator with it, also to disinfect it. ” "I also speculate that the potassium permanganate residue from refrigerator disinfection has been stained on this piece of meat.
Having said that, although the disinfection effect of potassium permanganate is good, it is toxic after all, it belongs to the three types of precursor chemicals, and the state control is relatively strict. ” Wu Duan remembered the chemical that would dye the water purple when dissolved in water.
He even remembered that one afternoon in middle school, the teacher showed everyone this beautiful purple liquid.
Wu Duan deserted at that time, fantasizing about what the girl he liked would look like if she wore a hairpin of this color.
He sensed something, an inspiration was coming, and Daigo's empowerment was just around the corner, but it was a small step away.
Wu Duan was silent, he even lowered his head and closed his eyes, allowing himself to calm down completely, allowing his perception to extend its tentacles to the longest, to try to touch the inspiration that was about to arrive.
After a few seconds, Wu Duan knew that he had failed.
He opened his eyes and asked Mink Fang, "Is there anything else?"
Mink Fang shook her head, "I'll try again, change a few more test ideas, in short, I will notify you if I find something." ” "Thank you."
Wu Duan took off his gloves and patted Mink Fang on the shoulder, "It's hard work, let's go back early today." ” "Don't worry, I'm measured."
Every detective thinks he has a sense of proportion, but they all work the same hard when they work overtime.
Wu Duan knew everyone's situation very well, so he didn't persuade much.
Back in his office, he flipped through his notebook and tried to write "potassium permanganate" on the page with the clues.
As soon as he wrote two words, he stopped writing because he saw the "chalk ash" recorded in the first line.
After "chalk ash", a straight arrow points to the word "teacher".
Now, he has connected "teacher" and "high manganese" again, and wrote "chemistry teacher" on the connecting line, and put a big question mark.
Unable to complete the unfinished word "potassium acid", Wu Duan said loudly to Feng Xiaoxiang: "I need information from the chemistry teacher in Mocheng."
All chemical veterans who meet the conditions of the deceased do not" Wu Duan stopped talking by himself, causing Feng Xiaoxiang to turn around and express his doubts expressionlessly.
"No, no, no, it doesn't have to be the deceased, it may be that the murderer's family used potassium permanganate, or they are a family at all It is not to meet the conditions of the deceased, but the information of all chemistry teachers in Mocheng, including those who are on the job and those who have left their jobs in the past two years. ” "It's a little bit big."
Feng Xiaoxiang said.
"There's a bigger project, and the system you developed last time, which is to quickly investigate the target's interpersonal relationships, can also be used.
I wanted not only the information of these chemistry teachers, but also their spouses, close relatives, friends, and lovers.
See if any of the people close to them are missing. ” Feng Xiaoxiang made a slight estimate and said, "I need two hours." ” "Okay."
As soon as Wu Duan's words fell, Yan Sixian entered the door with a laptop in his hand.
"Smile, help me see if you're busy."
Feng Xiaoxiang didn't reply, only sighed, "I said, you can't do it without me." ” When the detachment leader and deputy detachment leader were speechless, she calmly added: "And Sister Ermink." ” The friendship between women is really not something that men can see, and they have to bring their sisters to buy cheap.
"You are so good, my uncle will send you a little red flower," Yan Sixian replied unknowingly.
Feng Xiaoxiang didn't answer, leaving him with a sinister back, which made Yan Sixian instantly want to retract what he had just said.
"What did you find" Wu Duan interrupted the two of them at the right time.
"It's not special, it's just a student."
"Student" Wu Duan came to the computer that Yan Sixian had just put on the table.
Yan Sixian turned on a surveillance video.
"This is the intersection monitoring of the section where the target trash can is located, what do you see" "Well, it's school hours, there are a lot of students, I remember there was a school near there, covering elementary and junior high schools."
"Okay, keep watching."
Yan Sixian fast-forwarded the video screen, and Wu Duan always paid attention to the time in the lower right corner of the screen.
Nearly an hour and a half after the video was on, Yan Sixian pressed pause, resumed the original speed, and continued to play.

"Look again."
At this time, it has passed the peak of students leaving school, but the rush hour of work is coming.
There were significantly more vehicles and pedestrians on the road, and there were also sporadic students who were caught up in the crowd.
After being prompted by Yan Sixian, Wu Duan knew that he should pay more attention to the students who came and went, but he looked again and again but found nothing abnormal.
Yan Sixian pressed the pause and threw Wu Duan an inquiring look.
Wu Duan shook his head, "Why don't you just say the answer?"
Yan Sixian stretched out his finger and pointed, "This student's school uniform is different from others, he is not from the same school as them." ” "Uh" Wu Duan pondered for a while, determined that his train of thought really couldn't keep up, and said in frustration: "What does this mean?"
"Doesn't mean much."
"Ahh Wu Duan felt his jaw drop to the ground.
"This is the only one I can find out from the video" Yan Sixian shook his head with a wry smile, "It's not even a clue, at most it's just a bit of a disobedience." ” Wu Duan didn't bother much, he only said that Yan Sixian must have a reason.
Wu Duan had already begun to think.
He pointed to the surveillance screen and said, "Do you know what school he is?"
Yan Sixian shook his head, "There should be the word school on the front of the clothes, but it's too small, the monitoring probe can't shoot it, and it can only be compared through the style of the school uniform.
While speaking, Yan Sixian had already picked up the computer and rushed to the office of the Internet Supervision Department.
A few minutes later, he came back with his computer in his arms, and saw that he had already communicated.
He picked up the topic just now and explained to Wu Duan: "I watched the surveillance in the last month, just to observe him.
During the school period from Monday to Friday, the child went out more than an hour earlier than other children every day, and came back more than an hour late.
I searched for the uniforms of a few key middle schools and aristocratic schools, but I couldn't match them, which means that he worked hard to cross districts, but he only studied in an ordinary school.
So why not study nearby, what do parents think, there is a saying in the workplace: the distance between the company and home determines the happiness when going to work.
It's the same when applied to students, when the distance is far away, the children are guilty, and the parents don't stop.
That's what makes me think this kid is unusual.
Of course, there are some psychological implications, and when we mentioned school earlier, I paid special attention to school-related things. ” It's school again This made Wu Duan pay more attention to this clue that couldn't even touch the side of the case.
"You don't have to explain to me," Wu Duan said, "If you think there is a problem, just check it."
I believe in you. ” "I know.
I just can't accept an investigation that may be a waste of manpower, and explaining to you is also convincing myself. ” "Then I'm afraid you'll have to convince yourself often in the future, just get used to it."
The wait is always very long, and there is only Feng Xiaoxiang's monotonous keyboard tapping sound in the office, which makes people feel that their morale has been greatly reduced after listening to it for a long time.
Fortunately, the Network Supervision Department was very effective this time, and quickly fed back the results, and overfulfilled the task.
The head of the Internet Supervision Section took a printed news message and said to Yan Sixian: "Team Yan, the student you asked us to check is a celebrity." ” "Celebrity" Yan Sixian glanced at the news, "Do you have any misunderstanding about celebrities, you can't be called a celebrity if you have been on the news." ”:
