Controlled experiment

Xiaobai's words shocked Du Yusheng.

He suddenly found that all the fragments in his mind were connected by a thread.

The people in the photo, including Luo Daheng and Chen Xin, have experienced together that they all knew this person surnamed Jing.This Jing is an arms dealer, and all he does is illegal business. Could it be said that these few people also have a foot in Jing's business?Du Yusheng scratched his chin, he didn't want to understand.

What is even more incomprehensible is that not only Luo Daheng and Chen Xin died, but also his own father.

Mr. Du and this man surnamed Jing didn't know each other at all, so why were they involved.

Or, the old man had something to hide from him, even hid it in the coffin.

Du Yusheng glanced at Xiaobai.

He took a deep breath and said, "This arms dealer needs to do a thorough investigation, including how he died, the people in the photo, and the few who are still alive. Don't leave any one behind. I want to know what they have done recently and what they are going to do, and nothing can happen to any of them."

Xiao Bai blinked his eyes, his little face was pale, he felt that he seemed to have said something wrong just now.

"Luo Daheng, Chen Xin's case is very likely just the beginning." Du Yusheng lit a cigarette, and said, "The murderer we found is also likely to be a mediator, and we haven't found the person who really wanted to kill them. The key The point should be on this arms dealer."

Xiaobai thought for a moment, Du Yusheng was smoking a cigarette, the orange dotted sparks were at the end of the cigarette, Xiaobai felt his brain tightening looking at it.

Although Xiaobai didn't know the truth of the matter, his intuition told him that Du Yusheng was approaching them.

"Then I'll check." Xiaobai said.

Du Yusheng glanced at Xiaobai and shook his head.

Du Yusheng didn't know the relationship between Li Yao and Xiaobai, so he didn't want to take the risk yet.The most important thing about a riddle is to be able to guess the answer. Du Yusheng has been waiting for this answer since the day Du Yusheng found out that Mr. Du died. Du Yusheng didn't want any mistakes in this line.

"You and I will check the two items in hand. Let's settle the case first." Du Yusheng paused for a few seconds and continued: "I have to find someone else to investigate the photo matter besides the bureau."

"Who are you looking for?" Xiaobai answered.

Du Yusheng rolled his eyes at him.

He held back some words for a long time.

"Mubai." Du Yusheng rarely named his name and said, "Trust is mutual. You have lied to me, and you know it in your heart. You can still follow me because I still believe in you, but you have to let me feel that you I believe it. You were transferred from below. Even if you joined together, it didn’t take long to join the job. This arms dealer has been dead for at least ten years. You can recognize his face at a glance. If you are me, you how to think?"

Xiaobai wanted to explain, but Du Yusheng stretched out a finger in front of the two of them.

"You don't need to say anything." Du Yusheng said with a smile: "I still say that, you have to make me feel that you are worthy of my trust."

Xiaobai wanted to explain that he hadn't lied to him.But there are too many lies, and if you tell the truth occasionally, no one will believe it.

Du Yusheng could have continued to ask, even Xiaobai was already ready, so he asked what he wanted to say, but he opened the car door, motioned Xiaobai to sit in, and said nothing.At this time, silence is better than sound, and Xiao Bai didn't have much ink in his stomach, so he actually felt that this poem was appropriate to the occasion.

Colleagues coming and going outside the car passed by one by one with the physical evidence they had just found.

In Du Yusheng's view, all the things Chen Xin found at home were not as important as the photo he saw.

Xiaobai could easily recognize the arms dealer's face. This fact made Du Yusheng feel terrible. He was like a puppet, and he didn't know who had the command line.Du Yusheng rubbed his face and flipped through his phone. The address of the milk delivery company was sent quickly. Du Yusheng opened the navigation and took a look. The milk delivery boy lived far away from here, and it took four or ten minutes to drive.

What kind of motivation can make an ordinary milkman move to kill.

Du Yusheng turned on his phone and looked at the yellowed photo, his eyes scanned the people in the photo back and forth, and finally stopped at the arms dealer in the middle.In this photo, he is not very old, he should be of the right age for marriage in the tradition, he is smiling slightly, although his facial features look a bit fierce when integrated, but his eyebrows and eyes are very clear and beautiful when viewed alone.

Somewhat familiar, it reminded Du Yusheng of someone.By coincidence, Du Yusheng opened WeChat and sent a WeChat message to Li Yao.

'Do you know someone named Jing'

After sending ten words, Du Yusheng locked the screen as if he was afraid that he would regret it by withdrawing it.

==

Although the milkman's house is a little far from the expensive school district, it is not dilapidated.

The community is a high-rise residential building with complete facilities.

In this place, even if it's just renting a room, the little brother's milk delivery salary alone is far from enough, so where does his money come from.

Du Yusheng scratched his face and sent Xiaobai to ask at the property, while he parked the car himself. After confirming that Xiaobai was out of his sight, he opened the phone's address book and dialed He Shen's phone number.Although this grandson is a dude, he can check people's backgrounds, even who in their family cheated, and who often goes to nightclubs.It's probably because He Shen has been around for a long time and made friends in various entertainment venues. In that kind of place, good and bad people are mixed, and something can always be tricked out.

There is a gentleman in his name.

Lao Tzu He Shen always hoped that he could act like a gentleman, but what He Shen likes most is spending money and playing. "I said, did you receive the WeChat message? Give me a message." Du Yusheng said.

He Shen could only listen to the hustle and bustle in broad daylight, like a concert.

"Du Yusheng, let me tell you that there is nothing wrong with you." He Shen looked at the WeChat picture sent by Du Yusheng and said, "What do you mean by mosaicing everyone else and leaving only one in the middle? Let me check him? This Isn't it your business?"

The background sound was too loud, and Du Yusheng really wanted to press the noise reduction button on his phone.

"This man is dead." Du Yusheng roared: "I want you to check his life. He was an arms dealer. This kind of thing is tricky. After a person is dead, there is no proof of his death. No one dares to say that he has made a deal with the relevant people." He has something to do with it, and I will find someone in the bureau to investigate, but I still want to hear what you can find out."

He Shen was a smart person, and he immediately realized that it was not easy for Du Yusheng to investigate this person.

After getting out of the clubhouse, I went all the way to the parking lot, got into my car, and then called again.

"You want me to investigate a dead person?" He Shen lit a cigarette and said, "Arms dealers... need to work harder."

Du Yusheng didn't understand, and said, "What do you mean, what is hard work?"

He Shen smiled, scratched his eyebrows, and said, "I'm missing an ornament on my wrist, it's empty, it's uncomfortable to look at."

Du Yusheng cursed on the phone.

"Go to my place next week to pick it up. Even if you don't think I'll buy it for you, I'll buy it from the ends of the earth."

"Alright." He Shen said with satisfaction, "Thank you, Young Master Du."

Before hanging up the phone, Du Yusheng reminded, "Be careful."

Although He Shen is a playboy, he can do what he promises, and he can be regarded as the safest person among Du Yusheng's acquaintances.Du Yusheng was relieved to leave the arms dealer to him.With the results of He Shen and the results of the bureau's investigation, Du Yusheng felt that the matter of the arms dealer could be dealt with differently.

After hanging up the phone, Xiaobai's figure appeared in the rearview mirror.

Du Yusheng opened the car door and walked down.

"Brother Yu, I got it." Xiaobai pointed to the floor where the little brother lived, and said, "The owner of this house is Yu Liang, and he is the milkman."

"He bought this house?" Du Yusheng snorted coldly, "Where did you get the money?"

Yu Liang's house is in the middle of this building.Each floor of the community on this side is divided into two sides, with three households living on each side, and a total of six households on the first floor.Yu Liang's house is in the innermost room.Du Yusheng stood at the door and took a look. There was a circle of small advertisements around the door of Yu Liang's room. It seemed that he cherished it quite a bit, and had torn it down a lot, leaving some traces left.

Standing at the door, Du Yusheng looked at the door.

Three times, no one answered.

Du Yusheng winked at Xiaobai, signaling him to open the door.

The smell of disinfectant flooded into the nostrils of Du Yusheng and Xiaobai in an instant.

Xiaobai scolded, and said, "Isn't it that you used disinfectant to paint the wall?"

Two rooms and one living room, no one is there.

Du Yusheng looked at Xiaobai and said, "Is Yu Liang going to work today?"

Xiaobai shook his head: "I just asked, go to work."

"Give it away for a day? It's already afternoon, what about others?" Du Yusheng asked.

Xiaobai sighed: "Should I go out? Didn't the security guard say that there is still delivery in the afternoon?"

Coupled with the pungent smell of disinfectant, Du Yusheng had a bad feeling.

This premonition is the same as that day when I found out that Luo Yang's house had been redecorated.

If Chen Xin's family is simple, then the milk delivery boy Yu Liang can be described as luxurious.His furniture is very ordinary, there are no decorations, and the household appliances are the most low-end and most common configurations, but he has a cabinet, which is full of expensive wine.

The cabinets are made of hidden compartments, which cannot be seen until they are opened to the second floor.

When Du Yusheng used to go out with his friends, he saw a lot of wine in the wine estate, and the owner of the winery also likes to collect them.

But compared to those hidden in Yu Liang's house, they are almost rare.

Xiaobai opened his mouth wide and said incredulously, "Yu Liang is hiding something. Where did they come from?"

"Where else can it come from." Du Yusheng sneered: "I bought it with money. Or did I brew it myself?"

Xiaobai choked for no reason, and said, "...where did the money come from?"

People who like to collect have one thing in common. They may not pay attention to the clothes they wear, but they are willing to spend money on the things they like.Obviously Yu Liang belongs to this category of people.He has money to store the red wine in this cabinet, but the furnishings are very ordinary, which is easy to understand.

But Du Yusheng didn't understand why he was an ordinary milkman even though he was rich.

The biggest possibility is that he doesn't want others to know that he is rich.

But why.

Du Yusheng opened a drawer in the living room.

There was an ID card in the drawer, and Du Yusheng cursed while holding the ID card.

"His name is not Yu Liang." Du Yusheng said: "The ID card he showed us is fake, this one is real."

Xiaobai looked at the word 'Zhao Liang' on the ID card and cursed.

I took a picture and sent it to the staff.

Ten minutes later, Xiaobai received a reply.

Du Yusheng was sitting on the sofa in Zhao Liang's house, eating the oranges on the tea table. The whole room was covered with disinfectant. In other words, they were all carefully cleaned by the owner. Not even a trace of use.

This is very similar to the renovated state of Luo Yang's house.

Obviously, they all wanted to erase the existence of something, or in other words, they wanted to erase the traces of someone who had been there.

After eating the last sour orange, Du Yusheng took Xiaobai's phone and glanced at it.

"This Zhao Liang is a loan shark." Xiaobai explained while flipping through the pictures, "It's a coincidence that he is not from this city. He was originally a local snake and a loan shark with a criminal record. Fingers, selling other people's organs, and then he got into it for some reason, he became a usurer, and he knew the consequences better than anyone else, and he couldn't afford it, and then this person disappeared." Xiaobai took He glanced at his ID card and said, "It seems that he came to a new city and got a fake identity."

"Large profit." Du Yusheng pointed to the red wine in the cabinet, and said, "Does this really look like you owe money?"

Xiaobai laughed, and said, "It's easy to understand delivering milk. He doesn't want Lufu to be targeted and know his identity, but how did he get the money for this cabinet of red wine? He obviously owes a lot of debt."

"You have to find someone else."

Xiaobai nodded and said, "I have already sent someone to look for him in the community where he works."

Zhao Liang's study room is directly connected to the balcony, and the lighting is very good.

Du Yusheng walked in and took a look.

There are not many things on the table, only a laptop and a few pens.Du Yusheng first opened the drawer under the desk in the study.Then he saw a black telescope, and next to the black telescope was a package of yellow powder, which was well plastic-sealed. Du Yusheng felt that the package of yellow powder should be the same as the one in the vent of Chen Xin's ward. , drugged.

Take the evidence bag and stuff the powder and telescope into it.

Du Yusheng looked at these two things, and the two lives in his hands were finally settled.

Xiaobai looked at the two things in Du Yusheng's hand and frowned, and said, "Brother Yu, why did you say he wanted to kill Chen Xin and Mr. Qian? Even if Mr. Qian died because of Chen Xin, a milkman, or a How can a loan shark have such a big enmity with Chen Xin that he insists on killing him?"

"I'm more concerned about the note of the controlled experiment." Du Yusheng said: "This is not the first time, the murderer is different every time, is it really a gang?"

The binoculars and drugs, this incident can basically determine that Zhao Liang is the murderer.

Even if he wasn't, he couldn't get away with it.

Du Yusheng turned on Zhao Liang's laptop.

It can be opened easily without a power-on password.

Zhao Liang's computer is very clean, there are no pornographic discs, no weird songs, not even a game.

Du Yusheng opened the history of his computer's browser, and there was only one record.

Soon, a black and white web page was opened.

This is the last webpage that Zhao Liang opened on his computer.

The design of the webpage is very simple, black and white, with a white background, and the words 'Game of Death' written in big black characters in block letters.At the bottom are two blank lines without any text.However, Zhao Liang's computer is likely to be designed with the function of automatically saving the account password. Although there is no text in the two lines, there are six asterisks instead.

Du Yusheng clicked the enter button below.

The internet speed seemed to be a bit slow, and Du Yusheng refreshed the page after more than [-] seconds.

Still white background, black text.

Only one sentence.

'The user is logged out'

Du Yusheng felt that there were two meanings for the cancellation written on it.

One is account cancellation.

another.

It is the logout of the person.

So how would Li Yao reply to WeChat, hahahaha 'You asked me so directly'
