Swallowing the Seas

Outside the house, a group of forensic tracers carrying boxes and copying boxes were waiting in full force. The room was covered with inspection boards, and the criminals were squatting on the ground wearing light blue shoe covers, and the flashes were crackling.

Bu Chonghua walked out of the house to take a breath of fresh air, and saw that the villages in the distance were full of low and cramped illegal one-story houses. Residents in their spare time were either crowded outside the cordon in twos and threes, or stretched their necks to look out the windows, curious. Discussions erupted one after another.

Xiaobeizhuang was originally an empty village. In the past two years, due to the expansion of the city's fringe, it has gradually developed a preliminary village economy. However, it is generally a group rental house for migrant workers and waste pickers.According to the last registration report of the police station in the jurisdiction, there are about [-] households in the village, but Bu Chonghua knows that in some urban-suburban villages with high mobility and poor living conditions, the numbers registered by the police station are basically not accurate.

There were no children in the onlookers, either swaddled babies or teenagers.That may be because the children who have not grown into labor after weaning from breast milk are left behind in their hometowns.

Bu Chonghua sighed almost inaudibly, and suddenly saw Wu Yu sitting in a police car with the door open not far away, smoking a cigarette, walked over to take a look, and saw that he was actually watching a video on his mobile phone:

"If you put aside your duty and name as a policeman, if you put aside your so-called belief and loyalty...if you are still alone now; would you dare to reappear and stand in front of me like you did back then?"

"What are you looking at?"

"Hiss," Wu Yu raised his head, "Why are you suddenly scary?"

Wu Yu would be frightened by people, it would be like seeing a ghost in broad daylight, and Bu Chonghua is probably the only one in this world who can get close to him without being noticed.

"Why are you still watching this?" Bu Chonghua asked.

"Just take a look." Wu Yu pressed the video stored in the phone album: "I don't understand what he means. Want to recruit me? Want to kill me with your own hands? Or both? You can't." Wish I'd run up to him single-handedly and go one-on-one with him."

Bu Chonghua suddenly had a strange feeling.It sounds absurd, but it's as if... the shark is implying that.

In this world, only you and I are hostile to each other, one-on-one, there is no one else, you are destined to die, no one can and no one deserves to disturb this kind of relationship arranged by fate.

He didn't show this weird feeling, "What kind of person do you think a shark is?"

"IQ and talent are very high, arrogant, strong desire to control, like to discuss philosophical topics, such as absolute freedom and political framework. Maybe when the BOSS reaches a certain level, the thinking is not in the same realm as us. "Wu Yu smiled, "Actually, I didn't observe him very well. I only got along with him for a few days, and the arrest operation failed."

"How did it fail?"

"I beat him to the ground with a knife, but it still fell short... Sigh!" Wu Yu put away his broken mobile phone, got out of the car and stretched long, sighing: "If I was one step faster, maybe I can also get a detachment leader Dangdang today."

This is actually a very weird thing.The famous "shark" in the dark net world makes the vicious criminals awe, fear, and dare not defy, and makes the well-trained Interpol hard to track, but it is hard to get ahead; I don't know how many radars there are every day. The server is trying to find his footsteps, but he is trying to use various methods to lure Wu Yu, hoping that he will stand in front of him again.

It seems that the big villain boss who is regarded as a strong enemy by superheroes from all walks of life is searching all over the world for the passer-by who used a fruit knife to smash himself to the ground. Little did he know that passer-by had already thrown the fruit knife away and hurried to the morning bus to go to work up.

A shark with tens of millions of bitcoins flowing in and out of his account every day, if he knows that he is destined and that the only opponent in this life is actually only concerned about the thousands of dollars in field allowances, he doesn't know how he will feel.

Bu Chonghua was silent for a moment, then suddenly asked: "If there is such a day, do you want to fight him one-on-one?"

"Fuck, are you kidding me? Going to fight the big BOSS of the dark net?" Wu Yu said in shock, "It's almost like begging for mercy with a plop, isn't it good to be alive?"

Bu Chonghua: "..."

Bu Chonghua couldn't help laughing. At this time, Rao Da, the chief of the trace inspection room, came running from a distance, "Hey! Hey!" After a few times, he waved his hands and said loudly: "Bu detachment! Come and have a look!"

"How is it?" Bu Chonghua strode over immediately.

Rao Da bent down and supported his knees to take a breath, and then straightened up, wondering: "Basically, it can be guessed that it is the scene of the crime, but there is a problem."

"what?"

"Too clean, nothing."

Bu Chonghua was taken aback.

This one-bedroom house made of bricks, tiles and cement was built by local farmers in Xiaobeizhuang. There are more self-built veneer buildings and handshake buildings in the local area, but small bungalows are rare.After the building was completed, the owner rented it out to a couple working outside, and the two sublet it privately, and then rented it out to "Sanqi", leaving nothing but a note and a few pieces of cash.

"After the murderer committed the crime, he tied up the corpse with wires prepared in advance, put it in a woven bag, and then splashed bleach and detergent all over the floor and walls. In this way, on the one hand, the bleach will quickly wash away the blood at the scene, even if someone enters the house Checking can also cover up a little; on the other hand, hypochlorous acid will react with the luminol solution, causing the luminol to still glow even if there is no blood at the scene, thereby interfering with the judgment of criminal investigators."

"However, hypochlorous acid will volatilize in a few days in a dry environment, so when we are making luminol now, the luminol reaction is still very violent. You can see large jet-like blood splashes on the ground and walls. There are still a few drops that haven't been cleaned." The old man pointed to the two trace inspectors in the corner, who were concentrating on using the light beam to reversely extend and simulate the shape of blood splatter: "Let them take a DNA sample and compare it with the victim later. , but judging from all the clues, it is basically that the scene of the crime did not run away.”

Bu Chonghua actually already had a vague premonition: "So what you said is too clean means..."

"Yes." Chief Rao said, "There are no fingerprints, no footprints, no tooth marks, no biological evidence of the murderer. The toilet and wastebasket are clean, and there is no bodily fluid left in the preliminary investigation. Judging from the circumstances, I guess the murderer was not injured or bled during the crime. All in all, it was frighteningly clean."

—I don't mind letting the police know that I killed someone in this house, you know who I killed and how I killed it, but you'll never find out my name.

Now Kan came and went, the room was crowded with people, but this square inch fell into silence.

"Has the portrait of the suspect described by Diao Jianfa, Li Hongxi, and the subletting migrant couple come out?" Bu Zhonghua asked in a low voice after a long while.

"It's drawn, and it's being sent to the experts of the Municipal Bureau for completion." Rao Da carefully observed Bu Chonghua's reaction, for fear of accidentally touching his explosive point in this precarious state: "Once confirmed, we can send it out." As for the assisted investigation notice, as long as... as long as..."

As long as the police can find out the name of the murderer code-named "Sanqi", otherwise, only the suspect's own mother and wife may be able to recognize him based on a sketch that has been lost for a thousand miles.

"I see." Bu Chonghua waved his hand, and said lightly, "Go about your business, I'll see for myself."

Rao Da was glad that he escaped the crisis of facing the wrath of the squad leader, and hurried to work.

Bu Chonghua stood among the busy crowd and looked around.

"Sanqi" rented this room purely for killing people. He prepared woven bags filled with nitrogen fertilizer in advance, and after the killing, he took Chen Yuanliang's mobile phone and ran to a chemical fertilizer factory dozens of kilometers away to leave a base station signal exchange record. , All this shows his terrible anti-reconnaissance ability as a murderer.If it hadn't been for Wu Yu who discovered the difference in the old and new wires, and if Bu Chonghua hadn't used the degree of fading of the paint to delineate the radius of the body throwing distance, this crime scene might not be discovered by the police in the next few years.

So when this well-trained murderer was fully covered, not even urine residue in the toilet, not even a glue-stained handprint, where did the police extract his DNA?

What is even more absurd is that even if "[-]" is caught for other crimes in the future, what evidence will the procuratorate use to prosecute that he has entered this crime scene?

"Wu Yu!"

Wu Yu was standing next to the two trace inspectors in the corner, watching them pointing at the bloodstains on the wall: "Look, Xiao Wu, when the blood drop hits the surface at an oblique angle, the length of the trace and the angle of inclination or the moving speed of the bloodstain are equal to each other. In direct proportion, the greater the force, the smaller the blood drop... When we use the light beam to reconstruct the scene, we should pay attention to the fact that the height of the target after the reverse extension is higher than the actual height, because the trajectory of the blood drop is parabolic. The further the distance, the greater the error..."

"Wu Yu!" Bu Chonghua emphasized his tone.

"Thank you," Wu Yu thanked the two trace inspector brothers, and walked quickly: "What's the matter, leader?"

Bu Chonghua glanced at his colleagues around him, and asked in a low voice, "Didn't you say you asked me to teach you to solve the case, why did you turn around and find someone else?"

Wu Yu was taken aback, "So you can also analyze blood stain patterns?"

Bu Chonghua said, "Although I don't..."

"It's amazing!" Wu Yu didn't hear clearly, and sincerely praised: "As expected of you, you can do everything!"

"…………"

Bu Chonghua lowered his head and cleared his throat, and said calmly, "Of course I will, what's so difficult about it? I'll teach you later."

Wu Yu looked at the leader with shining eyes, and as soon as he opened his mouth to ask something, Bu Chonghua immediately interrupted him: "Now is not the time to teach this. There is no biometric evidence left in this room, you go with me Take a look outside the house."

Outside the house is a dusty dirt road, and the doors of every house are tightly closed.Barefoot teenage children yelled at each other, followed them far behind, poking their heads curiously, and the entire urban-rural junction village was immersed in a weird and exciting atmosphere.

"There's no road here," Wu Yu covered his mouth with his fist and coughed twice: "It's choking."

Finally, let's not mention that just now.Bu Chonghua raised his chin towards the road: "——road construction is not cheap. They are all villages that need to be emptied under the document. Where can I allocate funds for them to repair it?"

"How much is the road here?"

"It's hard to say. First of all, it depends on whether the roadbed is stable with water, ashes or slag. One square meter of concrete costs 400 yuan. If it is C25 strength, 3 meters wide and 15 centimeters thick, plus excavators and bulldozers , Concrete mixer, the average cost of one meter is at least 200 yuan, without labor." Bu Chonghua smiled: "So the ancients said that building roads and bridges is a great virtue."

Wu Yu nodded thoughtfully, and Shaoqing couldn't help but said: "Your price is too expensive. If it is to build a cement road, the roadbed is leveled and the cement is poured, and there are 50 yuan per meter. In fact, the requirements don't have to be so high."

Bu Chonghua's first reaction was 50 yuan per meter?Can people leave after the road is repaired?

Wu Yu took two steps forward, looked around the low concrete buildings, breathed out and muttered: "...the road should be repaired."

Bu Chonghua was behind him, took out his phone, turned it on, and quickly typed a WeChat message: [Urgently need a professional book on blood splatter pattern analysis, please borrow it, thank you. 】

The WeChat group of Class XX, XX-level Investigation Department of the Criminal Court, click to send.

Love makes people learn and progress.

He put away his phone, only to hear Wu Yu turn his head: "There are no fingerprints or footprints of the murderer left in the room?"

"There is no preliminary investigation." Bu Chonghua briefly repeated what Section Chief Rao said just now, and said: "Judging from the murderer's skilled murder and extreme care in cleaning up traces, this person must have a criminal record, and may even be a criminal." A fugitive. If his fingerprints or DNA can be found, there is a high probability that he can find his real identity information from the database, but now he is stuck at this step."

Wu Yu nodded and murmured, but couldn't think of any ideas, so he lowered his head and lit a cigarette.

They walked halfway around the village, turned back to the small bungalow from another direction, and suddenly smelled a faint smell from a distance.Wu Yu raised his head sensitively and looked over there, Bu Chonghua followed his gaze, and saw an open circle built with cement under a half-fallen brick wall, which was somewhat similar to an old stove. It was full of rubbish that was more than half the height of a person; several women were carrying garbage in plastic bags and throwing it into the already peaked garbage mountain.

The two stopped at the same time thoughtfully, and looked at each other.

"Hello, I'm sorry." Bu Chonghua stopped a woman, "How often do you collect garbage here?"

The woman didn't understand his question at all: "Huh? What are you talking about?"

Bu Chonghua repeated it several times before he figured out from the dialects of the other people that there were several "garbage collection stations" like this in the whole village, because this was originally an illegal settlement and there was no sanitation. The station is in charge of them, so I can only ask the waste pickers in the village to take the cart and push the waste to the Beidao Village landfill half an hour away. The frequency of cleaning is once a month.

"Once a month." Wu Yu murmured while standing by the garbage dump.

Bu Chonghua stood beside him: "Diao Jian's confession mentioned that he offered cigarettes to the agent sent by the shark, so the murderer should be a smoker..."

Smoking means throwing butts, throwing butts means saliva on the filter, saliva means—

The two of them looked at each other in blank dismay, and at the same time, they looked at the horrible, half-rotten, smelly garbage mountain. They saw the smelly water flowing from the bottom of the concrete circle, criss-crossing the ground, and mosquitoes and flies buzzing back and forth in mid-air .

Wu Yu patted Bu Chonghua on the shoulder, objectively and soberly: "This time Director Wang probably really wants to kill you."

"…………"

A man should have a sense of responsibility, and a criminal investigation team leader should have his own beliefs and responsibilities.Bu Chonghua gritted his teeth and took out his phone, and dialed his contact—Wang Ertu.

"Hello? The surname is Bu?" As soon as the call was connected, there was an angry voice on the other side: "Meng Zhao said that you asked people to hide all the braised egg sausages in your detachment and prevent me from taking them. What’s wrong with eating your eggs? You donkey wants to unilaterally destroy the regional bilateral trade customs union treaty of the Nancheng Public Security Bureau that we signed last month, don’t you?!”

Wu Yu: "..."

Bu Chonghua: "..."

"Jiu Ling." Bu Chonghua calmly said to the phone, "We haven't seen each other for a long time, and I really want to treat you to dinner tonight."
