As soon as Song Yuhang stepped into the training room, he saw several people surrounding Duan Cheng's computer.
"What's wrong?"
With lingering fear in his heart, Duan Cheng turned around and said in a stuttering voice, "Yes...someone replied to my post."
Lin Yan leaned over and saw that this was an anonymous forum. The ID of the person who replied to Duan Cheng's post was only a string of code numbers, and his avatar was a whale.
Song Yuhang glanced at Zheng Chengrui, and the other party immediately opened his laptop to look up the person's IP address.
"Team Song, I found it. It's in an Internet cafe in Dongcheng."
Song Yuhang made a phone call to the nearby police station.
half an hour later.
"Comrade police, I'm not really wronged." The sloppy man behind the bars sat on the interrogation chair with handcuffs on his wrists.
"I just... I just thought it was for fun, didn't the newspapers say... Someone might really commit suicide, I just wanted to see which idiot would be so stupid, who knew it was a fishing law enforcement by comrades in the police, hehe, hehe, really I'm sorry."
The investigator threw his pen on the table: "Is it enough to eat enough?! You call it disrupting public order, threatening public safety, and confusing the public. I don't know what it means!"
After a while, the criminal investigators came out to report: "Captain Song, I've asked you all. This person is a gangster who doesn't do business properly. He only graduated from elementary school. He can play games in Internet cafes. Writing codes and making programs is probably enough..."
Song Yuhang flipped through two pages of transcripts, threw them on the table, and leaned on the chair to rub his brows: "Okay, I will teach you a lesson after a few days of detention, so let's let go."
On the third day after the establishment of the task force, the investigation of the case had reached a stalemate, and everyone in the police station was exhausted. In the middle of the night, when Song Yuhang turned around, most of the people in the office were lying on their desks.
She sighed softly in her heart, got up and tiptoed to the wall, turned off the headlights, and prepared to smoke a cigarette outside.
When I arrived at the rooftop, I touched my pocket, and the cigarettes were all softened in the water, and I couldn't light them at all.
While hesitating, a white and slender hand stretched out in front of him, with an open cigarette case: "Here, there is no Zhonghua, let's make do with it."
Song Yuhang smiled, stretched out his hand to take one, and flicked the lighter a few times before it clicked: "Aren't you going to rest?"
"Aren't you too." Lin Yan said, and also stretched out his hand to protect the flames to inhale, and never wanted to have an ambiguous confrontation with her like before.
Song Yuhang looked at her movements, feeling a little lost, but she just said: "You should rest more."
Lin Yan smiled: "Closing your eyes is also a nightmare, it's better not to sleep and feel more refreshed."
Seeing her standing here, Song Yuhang couldn't help but think of the conversation in the corridor. She lowered her head and took a deep breath: "Is that question important to you?"
Lin Yan returned her lightly: "You should ask yourself, is it important to you?"
"I seem to have touched some thresholds, and I don't quite understand it. Just like this case, it seems to be close at hand but I have no idea." Song Yuhang said, his brows furrowed slightly. They were all bloodshot from staying up all night, the eye sockets were black and blue, the corners of the mouth were covered with dead skin, and the eyes that were so energetic from both sides also became dim.
The pressure to solve the case, the expectations of the deceased, and Lin Yan's words became the last straw that broke the camel's back.
Song Yuhang stood here, looking at the city under her feet, and she beside her was confused, confused and confused.
Lin Yan moved her lips, as if she couldn't bear it, but she didn't say anything, and put out the cigarette butt.
On the contrary, Song Yuhang saw that she was going to leave, turned around and said, "You wait for me, when this case is over, I will definitely give you a satisfactory answer."
As expected of Song Yuhang, work comes first in everything.
Lin Yan smiled, turned around and said, "I won't go home recently, I will sleep in the duty room."
Song Yuhang was startled, and understood what she meant.
You are welcome to come to me at any time if you have any questions, and I will do my best to solve the case.
More importantly, she understood what Lin Yan wanted to say but didn't say: Even if you can't answer this question, we don't know how it will end, but one thing will never change.
We are colleagues who get along day and night, and comrades-in-arms who live together and die together.
What a dark romance.
Song Yuhang's gloomy heart suddenly brightened, his brows stretched out, his sorrow faded away, and when she was about to step down the steps, he stopped her again.
"Hey, the smoke is still not tasty enough. Next time, please let me smoke Zhonghua."
Lin Yan turned his back to her and raised his middle finger.
Song Yuhang was overjoyed, but saw her wrist turned over again, which was clearly a cheering gesture.
The police officer couldn't hold back the joy at the corners of his lips any longer, he took two puffs and extinguished the cigarette on the railing. Looking at the busy traffic downstairs and the bright lights, his fighting spirit was rekindled in his eyes.

"Hey, Lingling, what's the matter with you, you're late today. Fortunately, the head teacher came late, otherwise..." After class, the companion kindly took her arm and shook it.
Bai Ling sat on the seat, lowered his head, and said nothing. The usually lively person was abnormally silent today.
The companion called out a few more times, and only then did the other party regain his sanity.
Bai Ling pulled her hand off his arm, his smile was a bit forced and pale, and it was only then that his companion noticed the injury on her face.
"I'm going to the bathroom."
"Hey, Lingling..."
It was too late for his companion to stop him, Bai Ling ran out of the classroom, rushed to the toilet in one breath, turned on the faucet and splashed water on his face.
People came and went behind her, some came in and some went out, talking about irrelevant and irrelevant topics to her, but she always felt a dark, vicious, and obscene gaze fell on her.
Everything that happened last night made her miserable.
Bai Ling choked with sobs, and put his hands on the sink, tears streaming down his face: "Why... why me... I... what did I do wrong?"
In a daze, she felt someone gently put a hand on her shoulder.
When she turned her head, it was the familiar stranger, still wrapped in a black robe.
"Bai Ling, look at yourself in the mirror, you, are you still you?"
Bai Ling opened his eyes wide, looking at the unrecognizable girl in front of him, no longer the purity and innocence of the past.
This girl with pain, remorse, struggle, sadness, and resentment written all over her face is not her, not her.
Bai Ling staggered back two steps, was supported, and the voice came again.
"Bai Ling, do you want to find your true self? Do you want to go to a place without pain? Come on, follow me, follow in the footsteps of the white whale."
"Bai Ling, Bai Ling..." Someone eagerly shook her shoulders and rescued her from that illusory dream.
She turned her head as if returning to her soul, and the teacher in charge touched her forehead: "What's wrong with you? Standing here talking to yourself, it's been half a day in class, if you don't feel well, please go home and have a look."
Bai Ling forced a smile, and bowed to the head teacher: "Thank you teacher, I'm fine, I'll go back to class now."

Early in the morning, the Jiangcheng City Bureau held the fourth task force discussion meeting on the "Moby Dick" case.
Feng Jianguo attended and Song Yuhang hosted.
After a short rest for a few hours, her condition was obviously much better than yesterday. The bloodshot eyes in her eyes dissipated a little, and she stood there in a police uniform with a heroic posture and a tall body.
"Since neither the search for the license plate nor the questioning of witnesses has made significant progress, let's change the direction and think about the suspect's motives for committing the crime, so as to deduce what kind of person might commit the crime to narrow down the investigation. scope."
She cast her eyes on the Technical Detective, Lin Yan stood up and handed in a report: "According to the autopsy results of He Miao, Fan Lin, and Wu Wei, this person was meticulous and did not leave any traces at the scene, and He is also proficient in psychological induction, and some kind of neurological drugs have been extracted from the blood of the above three people. I speculate that this person may be engaged in medical related industries, or have medical experience."
Song Yuhang nodded, and slightly bent the corners of his lips at her: "Secondly, this person is still a computer expert and can write programs and make codes. We boldly guess that his method of committing crimes is to find young students with suicidal tendencies on the Internet. , give psychological hints to him, and finally meet offline, force him to commit suicide by some means or drugs.”
"Then we can roughly draw the following characteristics of the suspect: the vehicle is black Santana, highly educated, proficient in psychology-related knowledge, has worked in the medical industry, and is currently unemployed."
"Knows certain computer skills, has Internet tools at home, is introverted, extremely psychotic, has a certain tendency to violence or murder, and likes to haunt at night more than during the day."
"Most serial murderers have previous convictions for animal cruelty, bedwetting, and arson, and this man is no exception, even worse. His childhood life should have been unhappy so that he planted the seeds of hatred in his heart. "
When she said this, she glanced at Lin Yan inadvertently. The man was sitting in a chair and spinning his pen idly, without looking at her at all.
Song Yuhang turned his face back again: "Due to the long time of committing crimes, I speculate that this person is over 30 years old. The ocean represents tolerance, broadness, power of life or mystery, and the white whale is the top of the food chain in the ocean. It is speculated that this person may have a special plot for such things, or that what he pursues, wants, and is obsessed with is all related to the ocean and the white whale."
In just one night, she completely cleared her mind and narrowed down the scope of the investigation. Everyone in the police station seemed to have received a shot in the arm, and excitement appeared on their faces. Even Zhang Jinhai had to sigh: Plastic talent, Young people are terrible.
As expected of Zhao Ting's valued person, Feng Jianguo took a sip from his teacup, put it down, and left quietly.
He was relieved to hand over this case to Song Yuhang.
In just one afternoon, a total of 68 people in their thirties were highly educated, related to psychology, related to medicine, worked in the medical industry, and understood computer technology from more than 4,000 owners of black Santana cars. .
From day to night, Song Yuhang didn't even have time to drink his saliva.

provincial capital.
"Didn't you say that this thing will never appear again?!"
There were three test tubes in front of them, emitting a faint blue light in the darkness.
The person sitting opposite looked at the test tube, his pupils shrank suddenly, he stretched out his hand and pulled a piece of toilet paper to wrap the tube body and picked it up.
"No... Impossible... It was destroyed long ago..."
"This is something presented by the Jiangcheng Bureau, can it be fake?"
As soon as he heard this name, the person opposite was shocked, and the situation in his eyes changed. After a long time, he put the test tube down again.
"It's over, what are you going to do?"
The man who was asked got up and walked to the window, bathed in the darkness, while outside the window was the beginning of the bright lights.
Darkness and light intertwined on him, struggling, and finally, the man took a step back.
"Check, give them the inspection report, but the samples must be kept."
＊＊＊
"Sister Lin, the fax is here." As the office secretary said, Lin Yan walked over and took the paper out of the fax machine.
Two thin sheets of paper, she took a cup of coffee and looked while walking. Song Yuhang was talking to someone, and he was also heading in this direction.
No one noticed anyone.
When Lin Yan came back to his senses, the coffee in his hand almost spilled all over his body, Song Yuhang quickly snatched it away, and at the same time stretched out his hand to stabilize her waist.
"Be careful and watch the road."
Lin Yan supported her shoulder with one hand, and quickly took two steps back. Seeing that no one was looking at him, he straightened his clothes and angrily took the coffee cup back from her hand.
"I should be the one telling you that."
Song Yuhang smiled and passed her by.
Before taking two steps, Lin Yan fell back and patted the paper on her shoulder: "Wait a minute, I have a new discovery."
"γ-hydroxybutyric acid?" Song Yuhang was taken aback by this strange name.
Lin Yan repeated again: "Yes, that's right, γ-hydroxybutyric acid, a natural substance found in the central nervous system, can also be artificially purified, and exists in wine, citrus and other foods and fruits, and also exists in small amounts. in almost all animals."
"In medicine, gamma-hydroxybutyric acid has been used as a sedative to treat mental disorders such as insomnia, depression, and narcolepsy."
This is related to her profession. Of course, Lin Yan said it clearly and logically, but what she couldn't tell Song Yuhang was that the medicine she had been taking for a long time also contained this substance.
Thinking of this, Lin Yan's face was a little gloomy: "Overdose of this medicine can easily lead to death, and..."
She paused, and Song Yuhang continued to ask: "And what?"
"Long-term use will lead to drug dependence, and once the drug is discontinued, it will lead to a withdrawal syndrome similar to drug withdrawal."
Song Yuhang's mind was ringing with alarm bells, holding this thin piece of paper, he was so angry that he couldn't speak.
What a vicious method, both mental and physical control, it's strange if you don't go crazy and don't seek death.
"That is to say, if we find out the source of the drug, we will not be far from the truth."
Feeling that the mysterious veil of "Moby Dick" was lifted by her again, Song Yuhang was a little excited and eager to try, she turned around and took two steps, seeing Lin Yan's face was not very good-looking, she fell back again, pinched He squeezed her hand, grasped it tightly, and then let go.
"Hard."
Lin Yan's hazy heart seemed to be blown away by her smile and childish movements.
Her warmth still remained in his palm, Lin Yan picked up the folder and smashed it over: "Get out, eat my old lady's tofu again!"
＊＊＊
"γ-Hydroxybutyric acid, also known as GHB, the purification method is not complicated, a few beakers, distilled water can be done, but it must have its synthetic substance, γ-butyrolactone."
A bunch of big bosses talking about this series of chemical names in professional terms are a little confused, and their eyes are facing each other with blank expressions.
Lin Yanfu: "Okay, let me keep it simple. γ-butyrolactone is a spice, a common food additive on the market."
Song Yuhang sat in the chair, touched the piece of paper, and at the same time reached out to ask his colleague for a map: "That means, just search for all the food factories, chemical factories, and small workshops in Jiangcheng City."
Lin Yan nodded: "That's right."
Song Yuhang got up, folded the map and put it in the jacket pocket of the training uniform, loaded the gun bullets and stuffed them into the leather case on the back waist.
"The field team set off with me, targeting major food factories, chemical plants, and small workshops in Jiangcheng City."
"The second field team continues to screen and screen suspects."
"Network security, video investigation, and graphic investigation continue to pick up videos and investigate and monitor, especially various posts that spread suicide on the Internet. They would rather arrest and question them first than let a person suspected of committing a crime go away."
"Yes!"
With an order, each group is ready to go.
Lin Yan grabbed her arm: "I want to follow the second field team to have a look."
Song Yuhang frowned: "No—"
"Fang Xin is here, why can't I go?"
Song Yuhang still had lingering fears thinking about her recklessness last night, and he didn't know how many moths he would make if he didn't let her go.
If she is not in the Bureau, no one can hold her down. Instead of letting her act alone, it is better to be with the big team.
"Three chapters of the contract."
Lin Yan readily agreed: "There are three chapters in the agreement."
She was talking about packing up her things and preparing to meet up with the field staff, but the person who had already walked two steps turned back, looked around to see if there was no one there, and whispered in her ear: "I remember the # key."
Lin Yan's ears were gently brushed by the heat, the corners of her lips were pursed tightly, and a document was directly thrown on her face: "Get out!"
Duan Cheng looked up at them lying in the gap of the computer: "It's started, it's started."
Several people whispered.
"Let me tell you, tell you, Fayi Lin and Team Song were in the car that night..."
"What's in the car, what's in the car, you tell me!"
Several people leaned against each other, grabbing Duan Cheng's clothes from behind.
Duan Cheng unscrewed the cap of the Coke bottle, took a few sips and wiped the corners of his lips. Just as he was about to kill everyone, a shadow fell in front of him, and his words stopped abruptly.
Song Yuhang stood in the opposite seat, rubbing his face that was stunned: "Don't blame me for not reminding you."
As soon as she left with her front foot, an iron metal hardwood folder flew in the air with her back foot, and hit him on the head impartially.
"oops!"
Lin Yan snorted coldly and said, "If you don't want the pig's tongue, cut it off."
That's what he said, but there was a slight blush on his normally fair face.

When the woman came home from buying groceries, she just walked to the door of the house, and it happened that the police were visiting a family next door.
"If necessary, please cooperate with us."
"Yes, yes, that's for sure."
The neighbor shook hands with the leading police officer.
The woman didn't dare to look any more, put the vegetables she bought on the ground, took out the key from her bag to open the door, and poked it a few times without getting in.
The sound of metal colliding caught Lin Yan's attention.
"That is… "
"Oh, that's an old resident of our family home. She's not a doctor. Her husband died. The hospital looked at her as a pity, and she had to raise a child, so the house let her live there forever."
The woman's back is hunched, she is no longer young, her hair on the temples is a little gray in the setting sun, and even the hands that carry the vegetables and keys are a little trembling.
Lin Yan looked away, nodded slightly, and said goodbye.
After the woman entered the door, she heard the movement outside the door gradually dissipating, and seemed to be relieved. Then she put the dishes on the porch, changed into slippers, and went to the bathroom to wash her hands.
After washing his hands, he pushed open the door of the back room, and a smell of excrement mixed with the smell of disinfectant came to his face.
The woman pushed open the window in the house, and didn't dare to open it any more, so she managed to open a crack.
After finishing everything, she turned around and helped her son lying on the bed turn over, change the diaper and scrub clean. After everything was cleaned up, she touched the child's face, her face could not hide her grief, and put his pale and thin hands under the bed, and then After tucking the quilt for him, he got up to cook.
Just as the pot was heating up, there was a knock on the door. She glanced through the cat's eyes and saw that it was the policewoman who had just met in the corridor.
The woman opened the door, and Lin Yan took out her ID from her pocket: "Police, I want to ask you something."
