Hearing Tang Rannuo's instructions, the golden retriever dog barked twice, kept sniffing on the ground, and headed towards the door of the community.

Wanrong community has just changed the property before, at this time the access control device at the door is still under repair, the two players walked into the community openly, pretending to be an ordinary resident husband and wife, leading the dog, and walking towards the building where the incident occurred.

The two blended into the crowd of onlookers, Tang Rannuo quietly loosened the leash and let the golden retriever run out by himself.

As he ran, the dog crooked its mouth, shook its head, seemed to be dancing to some kind of eerie music, and rushed into the garbage heap at the back of the community as soon as it slipped away, and began to dig wildly.

Li Ang raised his eyebrows and said softly, "What is it?" ”

Tang Rannuo smiled and said, "Release the skill, you will know later." ”

Li Ang nodded, suddenly thought of something, and reminded: "Walking a dog without a leash is equivalent to a dog walking a dog."

Won't you accompany it to the garbage heap and stand next to it for a while? ”

“...”

The corners of Tang Rannuo's eyes twitched, and he didn't make any expression on his beautiful face wearing sunglasses.

As if she hadn't heard Leon's words, she pretended to be an ordinary resident of the community, looking curiously into the cordon, listening intently, trying to get information from the gossip of the community.

The deceased Xia Junqiang lived in a rented house, and his landlord happened to be among the onlookers.

According to the landlord, Xia Junqiang signed the rental contract about half a year ago, and he looks honest.

He seems to be working as a freelancer, writing programs to make ends meet, and is taciturn and unsociable.

According to the description of his neighbors, Xia Junqiang has always liked to stay at home and only go out on Saturdays and weekends.

Usually there are no relatives and friends who will come to visit, even if he goes downstairs to go out, he is still to pick up takeout, or go to the supermarket to buy some daily necessities.

A few days ago, someone saw him picking up the courier at the express locker in the community, but he didn't expect to die so inexplicably...... And the cause of death is unknown.

The residents of the community didn't know that Xia Junqiang was suspected of killing someone, and they were still chatting nonsense without a word.

Discussing that contemporary young people often stay up late, do not care about their health at all, and are in danger of sudden death at any time.

The landlord also sighed vigorously and complained in a low voice,

I'm afraid it's hard to rent out this house after someone dies.

Even if you find a tenant, the rent will have to be lowered a lot.

This part of the gossip was of little value, and Leon shook his head,

It was found that the official criminal investigators seemed to be still upstairs to investigate the scene, and they had no intention of coming down at all.

According to the information he heard at Wang Congshan's house before,

I am afraid that Xia Junqiang's strange death has attracted investigators from the Special Affairs Bureau, and they are now upstairs to assist the Yin City criminal investigators in their investigation.

Leon didn't think about making direct contact with the Secret Service, even if it was too dangerous to go through the vest...

He sensed something, turned his head sideways, saw Tang Rannuo give him a look, and immediately withdrew from the crowd in understanding, and walked with her to the path at the edge of the community.

"How?"

Li Ang spread his hands and said, "There is no way to directly obtain information about Xia Junqiang's body now, I suggest going to the stairwell of other buildings and using pocket binoculars to see the room rented by Xia Junqiang." ”

"Wait a minute, Maomao hasn't come back yet."

Tang Rannuo shook his head, raised his mobile phone, and looked at Li Ang calmly, "By the way, I have Xia Junqiang's personal information here, do you want to see it?" ”

"No, I have it too."

Li Angwan smiled, took out the disposable smartphone for the vest from his pocket, quickly swiped the screen, and browsed.

To find out the cause of the death of the program ape Xia Junqiang, it is natural to know his social relations first.

And the best way to find out social connections is to buy information about residents.

In the age of network information, people have actually lost their personal privacy rights at the objective level.

A mobile phone number is required to register an APP, bank card information and a detailed address are required for online shopping, and face recognition is required to enter Internet cafes, high-speed rail, and hotels, and ID cards are required.

Name, gender, telephone, address, education, travel records, hotel records, SMS records, online shopping records, driver's license information, bank card information, current positioning....

All information is stored by major companies and network operators.

It stands to reason that this information is separated from each other and will not be leaked.

However, the huge demand for information in the gray industry has given birth to the information trafficker industry.

The debt collection industry needs the phone number, address, and address book information of the debtor, the fraud group needs a lot of citizen information, and the real estate agency needs the information of the buyer...

demand, resulting in benefits,

profits, giving rise to the production industry.

Businesses in charge of private information sell citizens' information in their systems to information dealers, who in turn build up huge databases and sell them to customers who come to their homes.

This database is so large, complex, cumbersome, and all-encompassing that it can even be customized for those who can afford it.

With a fee of hundreds or thousands of dollars and a mobile phone number, all the information of the owner of the mobile phone number can be provided within a few hours.

Household registration, hotel records, criminal records, ID card tracks, work tracks, education tracks, mobile phone positioning, mobile phone bills, payment software bills, real estate certificates, marriage certificates, birth certificates....

In the age of network information, everyone is transparent.

When Leon was not in high school, he learned about this giant database system that was free from the gray area, and used it to do some small experiments.

As early as when he was taking a taxi, he used the disposable anti-tracking mobile phone of the vest to enter Xia Junqiang's name and the name of the community in the database of the information dealer.

Eventually, Xia Junqiang's citizen information was found - the entire database system is set up on the dark web, and all processes from query to purchase are automated, without the need for human hands, just to transfer the money to the back office of the system (using a network currency similar to Bitcoin).

He had already known most of Xia Junqiang's information, but he didn't tell Tang Rannuo. There are two reasons for this.

First, it is to test whether the other party knows how to find personal information data and see if the other party is shrewd.

Second, it is to deter and threaten the other party - Li Ang already knows Tang Rannuo's address and name, even if she is using a vest identity now, she can abandon it at any time.

But the longer the vest is used, the higher the likelihood of revealing flaws,

The higher the probability of finding her true identity.

Presumably, the reason why Tang Rannuo told him to find Xia Junqiang's citizen information is the same - both sides have the ability to threaten the other party's true identity.

It's a pity that Li Ang, as the first to strike, changed his appearance in advance, concealed his whereabouts, and occupied a natural advantage in the matter of "concealing his identity".

Players are deceitful and intrigued, and the intrigue is not to be talked about for the time being.

Li Ang didn't care about Tang Rannuo, whose face changed slightly, swiped his mobile phone, quickly browsed all the information of Xia Junqiang, and roughly pieced together his life trajectory.

Male, 29 years old, Handong, parents divorced, grew up with the father of the freight driver, the family is average, excellent grades since childhood, his father died of illness in high school, he studied in the university in Yinshi, majored in computer science, and won awards in the ACM-ICPC competition with the team, without any hotel records (indicating that he has always been a single dog),

During his senior year, he had a serious illness, and after recovering from the illness, he entered a small and medium-sized Internet company as a developer.

After 6 years of work, he was fired by his boss and now works as a freelancer, relying on his programming skills and past savings to support himself.

There is no doubt that Xia Junqiang on the information is quite harmless to humans and animals, and he has a lot of savings in his bank card.

Without any reason or motive, pick up a knife and commit a burglary.

Unless, the two deceased knew Xia Junqiang....

Li Ang frowned, realizing that things were not simple.
