Huang Xingren, the director of technical investigation, is middle-aged, his head is shiny, his pace is hurried and his body is half sideways, and he jumps out like a machine gun: "The data was restored to eleven o'clock last night, and I came to work at four o'clock this morning...... Hi! His father and I have been trained by the head teacher as a grandson again and again, and you won't see me if you take the countdown to the exam this time, desperately don't want your life, Lao Tzu will beat him to death! ”

Yan Yu comforted him: "It's okay, can't you still be a policeman in the future?" ”

Huang Xing was stunned for a moment, his eyes fell on Yan Yu, and he subconsciously said, "That's not good!" ”

Yan Yu: "......"

"Where did you just go?" Huang Xing coughed casually: "Oh, yes, recover the data." ”

Yan Yu: ".................."

"The victim Feng Yuguang's photo album, address book, recent contacts, including WeChat account data have all been restored, and only WeChat chat records cannot be retrieved for the time being. The last call the victim received before his death was a non-real-name registered mobile phone card, which could not be triangulated, and the owner could not be determined. ”

Yan Yu pointed to the second line of the list: "What about this?" ”

It was an outgoing call, just three minutes away from the last mysterious access call, and the call lasted forty-eight seconds.

Forty-eight seconds, say long is not long, say short is not short; If it is an appointment to meet at a certain place, it will be too verbose, and if you talk about something else, there will not be enough time.

"Well," Huang Xing said, "the owner's name is Ding Dang, the daughter of the director of the company where Feng Yuguang interned, and a twenty-one-year-old art school student. The victim has been talking to her very frequently in the past month, and to be honest, I guess these two children are close to the water and fall in love. ”

Yan Yu smiled slightly.

Huang Xing said suspiciously: "What are you laughing at?" ”

"I laugh at you, you guessed wrong, the victim and this girl can't be in a relationship." Yan Yu shook the evidence bag containing the mobile phone: "Gamble or not?" ”

"......" Huang Xing said cautiously: "I advise you to look at the call records first." ”

"Don't look, I know."

"How do you know?"

Yan Yu smiled and didn't answer: "Bet or not?" ”

Huang Xing stopped doing it and said, "Aren't you raising the bar?" ”

"What a raise, I'm a reasonable guess based on facts. You don't fully understand the facts of the case......"

A figure hurried upstairs and almost hit Yan Yu on the head: "-Ouch! ”

Yan Yu's eyes were quick, and he dodged the white unknown liquid that splashed his face at the critical moment, and also saved the 200 yuan a dozen black T-shirts he bought from Taobao on Double 11 last year, and scolded: "What are you doing, panic!" ”

Han Xiaomei had soy milk in one hand and buns in the other, as if she was frightened: "Ah, Team Yan!" You, you, you, me, and I ......"

Huang Xing couldn't bear to see it, and he held his forehead.

"Are you here for work, or are you here for a picnic?!" Yan Yu was simply angry, "What about Lao Gao, Gao Panqing? Let you take this girl, and you let her run to eat steamed buns in the morning? Bring me the field team leader! ”

"It's not Brother Gao, it's not!" Han Xiaomei hurriedly stopped him: "It's Team Yan, your friend, I went to your office just now, and he said that you asked me to go and buy something to eat—"

Yan Yu: "......"

Yan Yu's face changed, like an active volcano about to erupt, and suddenly succumbed to the power of the gods and ghosts of nature called "Jiang Stop".

"Friends?" Huang Xingqi said.

“…… Oh, and the eyewitness I called in at the scene, and I forgot about him as soon as I got busy. ”

Yan Yu snatched the steamed bun and soy milk from the aggrieved Han Xiaomei, thought about it, stuffed it back again, threw the victim's mobile phone in the evidence bag to Huang Xing, and said: "Call out the people who have been in contact with the victim most frequently after arriving in Jianning, including this one named Ding Dang, call them one by one for questioning, and go back and ask Lao Gao to sort out a record for me." Then he snatched the steamed bun and soy milk again, glanced at Han Xiaomei up and down, and scolded angrily: "- How do you wear the police uniform?" Tuck your shirt into your pants! ”

Han Xiaomei: ".................."

Yan Yu carried the bun and walked away.

"Don't mess with these two fools." Huang Xing patted Han Xiaomei, who was about to cry, and pouted in the direction of Yan Yu's departure: "--A man in his thirties can't find a wife yet, how can there be no reason." ”

·

Yan Yu sat on the edge of the desk, shook the steaming plastic bag in front of Jiang Zhu, and retracted it the moment the other party raised his hand to take it, "Smack!" He slammed the case analysis report on the table and said, "Oh, let's do the work first." ”

Jiang Zhu's hand stopped in mid-air, and then calmly retracted it: "Don't look at it." ”

Yan Yu said: "What about you now, your net worth and life are in my hands, I advise you to be honest and obedient......"

Jiang Zhu raised his head, his face was as white as ice and snow: "Don't look at it." ”

Yan Yu was stunned by his dark eyes and bloodless face, and was stunned for a while, and hurriedly inserted the straw into the soybean milk cup with his own hands, tore the layer of paper under the skin of the bun, and served it in front of him with both hands.

Jiang stopped staring at him silently for a few seconds, and finally leaned over slowly, took a sip of soy milk from his hand, and took the morning as if forgiving.

Yan Yu knew that he was wrong: "You said that you have low blood sugar earlier, and you didn't tell me to stop and buy something to eat on the way here, who can blame you?" Oh, I've got half a pack of biscuits here, you see, no one is deliberately hungry for you, aren't you......"

"Fan Zhengyuan is taking drugs?"

Jiang stopped biting the bun while flipping through the analysis of the case, and stopped on the pages of the autopsy results.

"Nasal sucking plus intravenous injection, old fritters. How? ”

Jiang Zhu pointed to a line on the analysis report and explained: "Then how do you think that the phenyltamine compound in his trouser pocket is for himself?" ”

His question was exactly the same as that raised by Yan Yu at the case analysis meeting just now.

Yan Yu tasted excitedly: "Why didn't he eat it himself?" ”

"Intravenous injections are generally made of white powdered tetra-diacetylmorphine, which stimulates the release of dopamine by nerve migrating cells is very amazing, as long as the injection is over time, the number of dopamine receptors in the brain will decrease rapidly; So in order to achieve the level of stimulation that already exists, all heavy addicts will keep increasing the amount of injections. And the phenylamine synthesis in Feng Yuguang's body belongs to the lightweight level of seducing novices, and the nerve stimulation to Fan Zhengyuan is minimal, so it is unlikely that he will take it himself. ”

Yan Yu looked Jiang Zhu up and down, his eyes flickered slightly, and then he smiled a little strangely: "How do you know, maybe he just looks at this kind of pill conveniently, cheaply, and as a snack." ”

"Impossible." Jiang Zhu said casually while flipping through the report, "No. 4 diacetylmorphine is expensive to fool the layman, and I don't know how much glucose and talcum powder are mixed in the actual market, and the price is not necessarily higher than the phenylcrylamide synthesis." Besides, the strength of morphine is not over, and it will be very uncomfortable to mix with other smokes, so Fan Zhengyuan doesn't need to do that. ”

The only sound in the office was heard as he flipped through the autopsy report, and nothing else.

“…… You know a lot about the drug business," Yan said abruptly after a while.

This was obviously wrong, Jiang Zhu finally felt something, and his eyelids were raised, and he was colliding with Yan Yu's sharp gaze.

"-What are you looking at?" Jiang Zhu asked rhetorically, "I have been working on drugs for more than ten years, why don't I understand?" ”

Yan Yu was about to say something, when suddenly his mobile phone rang.

"Hey Lao Qin, well, okay, you can say ...... Yes, yes, found it? ”

I don't know what Qin Chuan said on the other end of the phone, Yan Yu jumped down from the desk, quickly grabbed the car keys, and picked up his coat: "Okay, you go to search for the surname Fan's home, send me another address, and I'll go over in person." ”

Jiang stopped eating his bun slowly, and the plastic bag was snatched away by Yan Yu: "Sensei eat, hurry up and follow me, eat while walking in the car." ”

Jiang Zhu frowned and said, "What are you doing?" ”

"The anti-narcotics detachment has found another hiding place for Fan Zhengyuan in addition to his home, and is preparing to arrange for an informant to take us there." Yan Yu looked at the buns in the plastic bag and pouted in disgust: "Tsk, custard." You have a picky appetite, can you be more squeamish? ”

He turned around and walked out with his bun, and suddenly slammed into the cold, and his cuffs were pulled by Jiang Zhu: "Wait." ”

"What's wrong?"

Jiang stopped Bafeng and sat in the armchair without moving, while Yan Yu stood, only to see him shake the analysis of the case in his hand, and said, "Your investigation is in the wrong direction. ”

Everything is like a repeat of the argument in the conference room three hours ago, except that Yan Yu's role has been reversed, and the party fighting for reason has been replaced by Jiang Zhu.

Yan Yu smiled secretly in his heart, but he didn't show it at all on the surface, and said coldly: "What's wrong?" ”

"The suspicion of the criminal investigation detachment about Fan Zhengyuan's involvement in drugs is based on the fact that drug residues were found on his body and he is suspected of armed robbery. But you and I know that Fan Zhengyuan himself has nothing to do with armed robbery, and the only purpose of his appearance is to kill me, but he was cut off halfway. ”

"So what?" Yan Yu said deliberately.

"Whoever killed Fan Zhengyuan can take anything from him, and he can leave behind. How do you know that the drug residue in his pocket is not a means for the murderer to induce the police to deviate from the focus of the investigation? ”

Yan Yu stood with his arms crossed, seemed to think for a moment, and said lazily: "No, your speculation has almost no factual basis, and it's no problem for the police to run to investigate Fan Zhengyuan, isn't it good for the murderer?" ”

——Deputy Director Wei's question was the key to Yan Yu's argument at the case analysis meeting, and he wanted to know how Jiang Shu would answer.

"Yes," Jiang said, "to buy time." ”

Yan Yu was stunned.

"I suggest that you send someone to follow up on Fan Zhengyuan's line, and at the same time increase your efforts to personally re-examine Hu Weisheng and re-investigate his residence, bank accounts, and mail exchanges." Jiang Zhu said: "The murderer did not hesitate to kill people under the nose of you, the deputy detachment leader, which shows that for him, the situation that needs to be covered up has reached a very serious level. If the police are led astray by him and the speed of investigation is slowed down, then Feng Yuguang's death is likely to evolve into an unclear ending like the Gongzhou case back then. ”

The two looked at each other for a moment, and Yan Yu narrowed his eyes: "...... When you were investigating the case, a similar situation occurred? ”

Jiang Zhu was indifferent to his scrutinizing gaze, got up and took the plastic bag containing the bag from Yan Yu's hand and threw it into the wastebasket.

"It's cold," he said.

·

In the seventies of the last century, the eastern suburbs established a huge and busy industrial area, vigorous production lines, independent hospitals, schools, post offices and other infrastructure facilities. Workers retire, children take shifts, state-owned enterprises manage the distribution of food tickets, oil tickets, meat tickets, bicycle tickets and even refrigerator tickets during the New Year's holidays, and the iron rice bowl is passed down from generation to generation, and most of the girls in Jianning are proud to marry into the workers' families in the eastern suburbs.

It was not until the late 80s of the last century that the glory gradually declined, and it was not until the 90s that a wave of layoffs was set off, and the large state-owned factories have since fallen into a thousand miles.

The once prosperous family area is now empty, and the ruined walls are broken under the sunset, and huge demolition words are written everywhere. Advertisements for faded instant noodles were plastered on the kiosk built in plastic sheds, and a few dirty children squatted by the ditch to play, screaming in a dialect accent from time to time.

Even driving a Ferrari in this kind of place is like a bouncing car, Yan Yu finally gave up, pulled the handbrake and extinguished the fire, and said: "No, if you drive it any longer, you will play acrobatics, please trouble the Jiang team, you will be tired and take two steps." ”

The dormitory in the industrial zone is an old-fashioned tube building, and now there are at least five or six empty rooms, not to mention ten rooms and nine empty. Although the afterglow outside was still there, the corridor was dark, and if he walked in a little, the dampness and mildew of the years rushed to drill into the seven orifices, and Jiang Zhi shivered: "Ah! ”

Yan Yu took advantage of the bright light of his mobile phone to open the way in front and said, "You are too delicate, aren't you?" ”

Jiang stopped and did not answer.

Yan Yu squeezed sideways through the mountain of debris at the corner of the corridor, carefully stepped on the steps that were difficult to get down, and finally climbed to the highest floor, the sixth floor. Clothes and quilts hung from the aisle facing the patio, and every door on the inside of the aisle was tightly closed, and the fourth door went inside, with a police seal attached to the dilapidated yellow wooden door.

Jiang Zhu hugged his arms in front of his chest, looking at the surrounding environment inch by inch, and suddenly saw Yan Yu handing over an army green jacket in front of him: "Hmm." ”

"No, you don't." Jiang Zhu didn't even mean to stretch out his hand: "I can't afford to pay if I break it." ”

Yan Yu was only wearing a black short-sleeved T-shirt, and his solid shoulder muscles were particularly obvious, so he couldn't help but put his coat on his head: "Come on, if you catch a cold and get sick, won't I be ...... when I turn around."

Jiang Zhu finally told the truth: "When was the last time you did your laundry?" ”

Yan Yu: "......"

The two stared at each other, and after a while, Yan Yu clicked the lock with the key, and said coldly: "Dress honestly, don't talk so much nonsense." ”

The room was damp and dark, and when I opened the door, there was an indescribable smell. Yan Yu covered his nose to turn on the light, who expected that the meter had been pinched, so he had no choice but to continue to use his mobile phone to illuminate, only to see that the ground was full of debris and garbage, and it was thoroughly checked twice by the investigators, and the whole Burrow was miserable.

Jiang Zhu cautiously stepped through the door and stood beside the low wooden bed, frowning slightly and observing the surroundings.

"The field team has searched twice, and Lao Gao's means, every mouse in this room has been named and registered." Yan Yu unceremoniously smashed him with his elbow: "Why, Team Jiang hasn't seen the living environment of the low-end population?" What do you think? ”

Jiang stopped taking Yan Yu's mobile phone, half-squatted on the ground, and shone it one by one under the bed, the crack in the ground and the root of the wall, and pondered for a long time.

Yan Yu teased: "What about you?" ”

"I don't have any feelings." Jiang Zhu said flatly, "I, a low-end population, also grew up like this. ”

Yan Yu was stunned.

Jiang stopped and walked to the table, only to see several hot water bottles side by side, sundries piled up on the shabby plastic plates that were so worn out that they couldn't be seen that they couldn't be seen, leftover instant noodles and "skating" pots were next to each other, and a thick layer of white mold had formed on the oil soup.

Jiang Zhu stood there, as if he had encountered some difficult problem, his slender black brows twisted, and the curve from his forehead to the bridge of his nose, his lips, and even his neck formed an elegant and unique silhouette in the light and shadow.

He suddenly pulled out a chair and sat down, Yan Yu didn't have time to stop him, only to see him sitting straight in front of the bowl of moldy and smelly convenience, as if he was reaching out to get the chopsticks.

"Hey, you're ......"

As soon as Jiang stopped raising his hand, Yan Yu's words stopped abruptly.

Immediately after, Jiang Zhu raised his head and looked thoughtfully at the other side, his gaze naturally falling on the broken window at the other end of the room, barely covered by newspapers.

Yan Yu didn't know what he was looking at, so he could only stare at him without blinking. I saw Jiang stop and get up and walk to the window, carefully searching for the oil-stained windowsills and wooden ridges by the light, and suddenly reached out and pushed the deformed wooden window sash hard.

Boom!

The window was pushed open, and the evening breeze blew in, and in an instant the disgusting smell of the room was washed away.

"-Come here," Jiang Zhu pointed to the outer window sill, his voice was not shocked, and said, "The work of your field team is also rough enough. ”
