Zhang Dingshan said very solemnly. Sensing his solemnity, the security officers who carried out this mission were also awe-inspiring in their hearts.

People have heard of the abnormal suicide in Blue Lake City. And the three people in front of them were the inspectors sent down by their superiors. They say it could be life-threatening, and that's true.

And......

Looking at it like this, these three people sent down from above seem to have some important clues?

The vigilantes were nervous and excited.

With the assistance of the local security office in charge of security on Nanlin Street, an investigation was carried out quietly.

There is a lot of movement of people here on Nanlin Street. The hotel opened and closed down, closed down and opened, today it is this boss who takes over, tomorrow it is another boss who takes over, and the flow is frequent. The same is true for the old residents, some of whom come here for a few months during this period of time, and then leave after a while, and some of whom have opened their own shops. In order to investigate who has stayed here for a long time, it is not enough to rely on file search, but must conduct on-the-spot investigation.

As a result, this year's floating population screening operation began ahead of schedule.

Such an operation is carried out every year by the Nanlin Street Police Station. Anyone who has been on Nanlin Street for a long time knows it.

It's just that this time, more elite soldiers have quietly supplemented and entered the front line of investigation. And the investigation process is more formal, and the attitude is better when communicating with merchants and residents.

This was specially requested by Zhang Dingshan.

If any of the vigilantes had a rude attitude, provoked the murderer hidden in the shadows, and lost his life in no apparent way, it would be too unworthy.

The entire process lasted three days. During these three days, every tenant, every tenant, and every household were all screened. And in accordance with the orders of the second operation team, the security officers also traced the past year during the investigation.

Such a huge operation, on the surface, has hardly attracted the slightest attention from unrelated personnel. Nanlin Street is still full of traffic and people. Every store is still full of customers during peak hours.

Three days later, all the investigative data was compiled here at the Blue Lake City Public Security Bureau. After screening with the previous restrictions, soon, one person's file was placed in front of the three members of the second team of the operation.

There are tens of thousands of permanent residents in the entire Nanlin Street, and only this one person meets those screening conditions.

This man's name is Wang Quan.

Zhang Dingshan, Lu Ming, and He Wei looked at Wang Quan's photos and information on the screen, with solemn expressions.

On the screen, Wang Quan is a middle-aged man with a slightly ugly appearance.

He has small eyes, thinning hair, an upturned nose, and pockmarks on his face. He was short, only 1.6 meters tall, and thinner, weighing only 53 kilograms. He is 46 years old, has a primary school education, and is unmarried. There is only one older sister in the family.

His parents have died. The only sister married away from other cities, and had a bad relationship with him, and after a big fight almost twenty years ago, she broke off contact.

Wang Quan is an old resident of Nanlin Street, and his family has an old house here on Nanlin Street, but there is no street frontage, and the commercial value is limited. Now it is in disrepair and dilapidated.

He has no legitimate occupation and currently makes a living selling a snack called "chestnut cake". He made chestnut cakes at home, and during the rush hour of dining on Nanlin Street, he pushed a small food truck to sell them on the street.

The side investigation showed that Wang Quan had an introverted and eccentric personality, and he basically did not interact with people.

As Nanlin Street has become a food street, its popularity has risen, and the old residents of Nanlin Street have made a fortune one by one. Even if you don't have a serious livelihood, you can rent out your family house to open a shop and restaurant, and you can live a good life with rent alone. There is no one like Wang Quan who has lived such a miserable life, and even the standard of living is not as good as that of ordinary people.

Such a person...... Could he be the murderer?

Looking at Wang Quan's ugly face, Lu Ming had a little doubt in his heart.

He thought that after mastering this kind of supernatural power that can make people commit suicide, even an ordinary person with a little brain, can use this ability to live a rich life without any hidden dangers.

Even, Lu Ming is already mentally prepared to find out an invisible super-rich. He really didn't expect that what he finally found out was such a person at the bottom of society.

Single, childless, no daughter, no stable income, living in a dilapidated house, no matter how you look at it, they are all at the bottom, right?

How could it be so miserable?

It can't be a mistake, right?

"Check it out first."

Zhang Dingshan made a decision.

"Yes."

The investigation of Wang Quan is still extremely careful and secretive. Zhang Dingshan gave a death order, no matter what, he must not be alarmed, or let him perceive that someone was investigating him.

After all, he has not cleared his suspicions, and there is a possibility of mastering supernatural powers.

When formulating the investigation plan, the security officers found that Wang Quan's stall had a roughly fixed location. And not far from his stall, there is a monitoring probe under the management of the Public Security Bureau. It's just that the performance of this monitoring probe is limited and the shooting is not clear.

With a phone call, Zhang Dingshan transferred a monitoring probe with ultra-high performance from other places and installed it directly. Not only that, Zhang Dingshan also asked Lu Qingliang to contact a cutting-edge acoustic laboratory and found a high-performance directional radio that is not available on the market and belongs to the customized category.

Such a radio can adjust the aiming direction on its own. Once aligned, even in a noisy environment, the sound of normal speech and communication of people up to 100 meters away in that direction can be captured.

Under normal circumstances, the distance between Wang Quan's booth and the monitoring probe and radio will not exceed 50 meters. In this way, both Wang Quan's image and voice will be fully captured.

After getting Wang Quan's "work" place, the security guards also made corresponding arrangements for Wang Quan's residence.

Wang Quan lives in an ordinary small courtyard that is basically indistinguishable from a farmhouse courtyard. On the street where Wang's family went to work, security guards also installed covert surveillance and radio devices.

On the exterior wall of his house, which belongs to another family, where things are installed almost undetectable to him, there is also an invisible radio that can be eavesdropped on the wall. On top of the building, which is up to 100 meters away from his house, high-performance surveillance equipment is installed, which can directly film his courtyard and windows.

As for the interior of Wang's family, no arrangements have been made for the time being. He Wei once proposed to find someone who was not there, sneak in and install eavesdropping and surveillance equipment in each of his rooms, but Zhang Dingshan still rejected the proposal after thinking about it.

The reason is very simple, before Wang Quan has supernatural powers, there may be unpredictable risks in entering his room without permission.

For now, it is still important to be on the safe side.

Thus, such a net of heaven and earth was built. And Wang Quan should be completely ignorant of all this.

In the early morning of the next day, the three members of the second team arrived at the monitoring room.

During the surveillance, through the window, the high-performance camera filmed Wang Quan still sleeping in bed. It was a few more moments before he rolled over and got out of bed. After that, I ate a little bit and started to get busy in the kitchen.

Steamers, dough, eggs, chestnuts and other items are already prepared. Obviously, he's going to start making chestnut cakes.

Lu Ming noticed that Wang Quan did not use natural gas delivered by the municipal system to make chestnut cakes, but atmospheric tanks purchased by himself.

Inquiring about the municipal natural gas system, Lu Ming saw that Wang's family had been connected to natural gas and had no arrears. Why use gas tanks, Lu Ming guessed that it might be because the natural gas firepower is not strong enough.

It was busy until near noon, and the fluffy and soft chestnut cake was made.

The chestnut cake was one board after another, one meter long, about 60 centimeters wide, and about ten centimeters thick. When it was time to sell it, he would use a knife to cut it into cubes about one decimeter in length and sell them piece by piece.

On this day, he made two plates. If you sell it, you can make 120 copies. The price of one serving, Wang Quan, set it at 7 yuan. If you buy 3 yuan, you will get a discount of 1 yuan, 20 yuan.

When it all is sold out, he can sell it for about 800 yuan. Excluding the cost, it can earn about 350 yuan.

This income seems to be not bad. However, according to previous surveys, Wang Quan usually can't sell so much in a day, and sometimes the weather is bad and he can't go out of the stall, so his income is a little unstable. On average, you can only earn less than 5,000 yuan a month.

But he is a bachelor, and this money is enough for him to spend on his life.

After making the chestnut cake, it was moved to the small food truck, and before going out, Wang Quan scooped out the water for the steamed chestnut cake and went out with a sewage bucket.

Not far from his doorway was the sewer. But instead of pouring the water down the drain, he poured it directly on the right side of the doorway.

The concrete pavement, which was already potholed and full of dirt, suddenly became muddy.

After that, he put the bucket into the house, pushed the small food cart, and walked in the direction of Nanlin Street on the left side of the door.

He Wei's brows furrowed.

"This man has no public morality. Can't you walk a few more steps? You have to splash water there. ”

Wang Quan went to Nanlin Street to go out of the stall, and after a while, Wang Quan's neighbor's door opened, and three little girls wearing the uniforms of XX hot pot restaurants went out together, and also went to Nanlin Street.

Seeing a large pool of sewage and mud in front of them, the three little girls were immediately unhappy.

According to the preliminary investigation, Wang Quan's neighbor has rented out, and the tenants are these three little girls.

The rent of this kind of farmhouse is very low, and it is very suitable for people who come to Nanlin Street to work and have poor economic conditions.

Their conversations were transmitted to the monitoring room through high-performance radios, and were heard by Zhang Dingshan and the rest of the security guards.

"That's too unqualified, isn't it?"

"yes, if you walk a few more steps, you can die?"

"Every day! Sick of it. ”

"Xiaoli, let's go find him! He was at a stall selling chestnut cakes not far from the street. ”

"That's right, make trouble with him! It's so unqualified! ”

The two little girls were indignant and wanted to go to Wang Quan to discuss the explanation. The other girl, who seemed to be the most mature and stable, hesitated for a moment, but still said: "Don't be, that person looks so weird, in case you start a crazy ......."

"Why are you so cowardly, there are three of us, one of him, and you are still afraid of him?"

"Still no, I've heard him sharpening his knives in the middle of the night several times...... It's horrible. Let's bear with it, save some more money, and let's live in another place. ”

“……”

The three little girls chattered and discussed for a while, and finally decided to endure and suffer some grievances.

So the three of them carefully picked a place where there was no sludge and bypassed here.

It's almost the noon rush hour. The number of people on Nanlin Street gradually increased, and Wang Quan also ushered in his first customer today.

"How do you sell chestnut cakes?"

Wang Quan squinted at the customer and casually pointed to the sign next to him.

"Get me three."

After that came the second, the third......

Until the afternoon rush hour passed, everything was normal.

Today, Wang Quan's business seems to be good. After noon, the first chestnut cake was almost sold, and only five pieces were left.

Another man bought three, and only two remained.

At this time, two people, a man and a woman, who seemed to be lovers, walked over. When the girl saw Wang Quan's stall, she came over with great interest and said, "Get me three pieces." ”

Wang Quan glanced at the girl, lowered his head, and took the chestnut cake silently.

In addition to the two chestnut cakes left from before, there is one less piece. But Wang Quan did not remove the cloth on the second chestnut cake, but took another piece of chestnut cake from under the cart.

The girl's face was suddenly unhappy: "When did this happen?" It's all dry, I don't want it, you cut it for me from the top of this new one. ”

Wang Quan said in a low voice: "It's all the same, it's all delicious." ”

"It's all dry, can it be delicious? I don't want this! ”

"I haven't started cutting this big piece yet, and it's not worth cutting just one piece...... Take this, the same. ”

"It's your business whether it's worth it or not, do you sell it or not? I don't want it if I don't sell it. ”

"It's all the same thing, and you have to let me cut a new one?"

Wang Quan's voice was a little unkind.

"I don't want to, do I? Hmph, go. ”

A man and a woman turned and left.

Wang Quan was instantly excited.

"You can't go! You look down on people, don't you? Bullying people, right? Rich is amazing, huh? Bullying me for being poor? What about playing with me? ”

His face was distorted, and his eyes were full of fierce light, as if he had been wronged by some great grievance, and like a wild beast.

The boy was also angry: "How can you speak? Who bullied you? If you don't sell it, we won't buy it? Why do you bully people? ”

"I'm all set, you don't want it, what is it that is not a bully? Is it easy for me to set up a stall? You see that I am poor and bully me, right? Look at me thin, see me short, bully me, right? You rich people don't have a good thing! ”

Wang Quan screamed wildly, and even picked up a knife in excitement. Although it doesn't mean to cut people for the time being, it's quite scary.

The boy was undaunted and was about to continue to discern, but the girl calmed down. She grabbed the boy and hurriedly said, "Uncle, don't get excited, let's buy it, can't we buy it?" ”

"Xiaoqing, don't be afraid of him! He ......"

The girl pinched the boy desperately, stopped his words, and then hurriedly took out 20 yuan and put it on Wang Quan's dining car, grabbed the three chestnut cakes and left.
