Hearing Tang Rannuo''s instructions, the big golden retriever barked twice,


    sniffing and sniffing on the ground, heading towards the gate of the


    community.Wan Rong Community had just changed the property before. At this time, the


    access control device at the door was still under repair. Two players walked


    into the community openly, pretending to be a couple of ordinary residents,


    leading the dog, and walked towards the building where the incident occurred.The two mingled among the onlookers, Tang Rannuo quietly loosened the leash


    and let the golden retriever run out by himself.While running, the dog was still tilting his mouth, shaking his head and


    shaking his head, as if dancing with some kind of weird music, rushed into the


    garbage dump at the back of the community and began to plan wildly.Li Ang raised his eyebrows and said softly, "What is it?"Tang Rannuo smiled and said: "The release of skills, you will know in a


    while."Li Ang nodded, and suddenly thought of something, reminding him: "Walking the


    dog without leashing it is equivalent to walking the dog.Don''t you accompany it to stand beside the garbage dump for a while? ""..."Tang Rannuo''s eyes twitched, and there was no expression on Jiahao''s face


    wearing sunglasses.She pretended not to hear Li Ang''s words, pretending to be an ordinary


    community resident, curiously looking into the cordon, listening carefully,


    trying to get information from the community people''s gossip.The deceased Xia Jun forced to live in a rented house, and his landlord


    happened to be among the crowd.According to the landlord, Xia Junqiang signed the rental contract about half


    a year ago. He seems to be acting honestly.His job seems to be a freelancer, usually relying on writing some programs to


    make a living, reticent and unsocial.According to neighbors'' descriptions, Xia Junqiang always likes to stay at


    home, only going out on Saturdays and weekends.Normally, no relatives or friends would come to visit. Even if he went


    downstairs, he would go out to get takeaway or go to the supermarket to buy


    some daily necessities.A few days ago, someone saw him picking up the courier from the courier


    cabinet in the community, but he did not expect to die so unexplained... and


    the cause of death is unknown.Residents in the community did not know that Xia Junqiang was a suspected


    murderer, and there was still a word of nonsense.Discuss 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 kept sighing, whispering,I am afraid it will be difficult to rent out this house after the death.Even if you find a tenant, the rent will have to be lowered a lot.The content of this part of the chat is of little value, Li Ang shook his


    head.It was discovered that the official criminal investigators seemed to be still


    upstairs investigating the scene and had no intention of coming down.According to the information he heard in Wang Congshan’s house before,I am afraid that Xia Junqiang''s strange death has attracted investigators from


    the Special Affairs Bureau, who are now upstairs assisting Yin City criminal


    investigators in their investigation.Li Ang didn''t even think about contacting the Special Affairs Bureau directly,


    even through the vest is too dangerous...He felt something, turned his head and saw that Tang Rannuo gave him a look,


    he immediately retired from the crowd with her heart, and walked around the


    path at the edge of the community with her."How to say?"Li Ang spread his hands and said, "There is no way to directly obtain


    information about Xia Junqiang''s corpse. I suggest going to the stairwell of


    other buildings and using a pocket binocular to see the room Xia Junqiang is


    renting.""Wait a minute, Maomao hasn''t come back yet."Tang Rannuo shook his head, raised his phone, and looked at Li Ang calmly, "By


    the way, I have Xia Junqiang''s personal information here, do you want to read


    it?""No, I have it too."Li Ang smiled, took out the disposable smart phone dedicated to vest from his


    pocket, and quickly swiped the screen to browse.To find out the cause of death of the program ape Xia Junqiang, one must first


    know his social relationship.The best way to ascertain social relations is to purchase residents''


    information.In the age of network information, people have actually lost their right to


    privacy on an objective level.Registering the app requires a mobile phone number. Online shopping requires


    bank card information and detailed residential address. Entering Internet


    cafes, high-speed rail, and hotels require face recognition and ID cards.Name, gender, phone number, address, education, travel records, hotel records,


    SMS records, online shopping records, driver''s license information, bank card


    information, current location...All information is kept 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 gray industry information demand gave birth to the


    information vendor 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, create benefits,Benefits urge the production industry.Companies in charge of private information sell citizen information in the


    system to information dealers, and information dealers build huge databases


    and sell them to customers who come to buy them.This database is so large, complex, cumbersome, and all-encompassing, it can


    even provide customized services for those who can afford it.You only need to pay a fee of several hundred or several thousand yuan, and a


    mobile phone number, and 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 track, work


    track, education track, mobile phone positioning, mobile phone tariff bill,


    payment software bill, real estate certificate, marriage certificate, birth


    certificate...In the age of network information, everyone is transparent.Before Li Ang was in high school, he knew about this huge database system in a


    gray area, and used it to do some small experiments.As early as when he was taking a taxi, he used the vest’s disposable anti-


    tracking and locating mobile phone, and entered Xia Junqiang’s name and


    community name in the information dealer’s database.In the end, I found Xia Junqiang’s citizen information—the entire database


    system is set up on the dark web. From query to purchase, all processes are


    automated, without the need for human hands, just transfer the money to the


    background of the system (using one A network currency similar to Bitcoin).He had known most of Xia Junqiang''s information for a long time, but he didn''t


    talk to Tang Rannuo. There are two reasons.One 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 currently using the vest identity,


    she can discard it at any time.But the longer the vest is used, the higher the possibility of showing flaws.The possibility of finding her true identity is higher.Presumably, Tang Rannuo told him that the reason for finding Xia Junqiang''s


    citizen information was the same-both sides have the threat ability to expose


    the other''s true identity.It is a pity that Li Ang, as the first to take the shot, changed his


    appearance in advance and concealed his whereabouts. He had a natural


    advantage in the matter of "hidden identity".The intrigue between players, intrigue aside,Li Ang didn''t care about Tang Rannuo whose face changed


    slightly~~ swiped his phone, quickly browsed all the


    information materials of Xia Junqiang, and roughly pieced together his life


    track.Male, 29 years old, from Handong, with divorced parents. He grew up with the


    father of a freight driver. He was in an ordinary family. He had excellent


    grades since childhood. His father died of illness in high school. He studied


    in Yin City and majored in computer science. He won the ACM-ICPC competition


    with his team. Past awards, no hotel records (indicating that they have always


    been single dogs),I got a serious illness during my senior year. After he recovered, I entered a


    small and medium-sized Internet company as a programmer as a developer.After working for 6 years, I was fired by my boss. As a freelancer, I rely on


    programmer skills and past savings to support myself.There is no doubt that Xia Junqiang in the information is quite harmless to


    humans and animals, and the savings in the bank card are abundant.Without any reason or motivation, he picked up a knife and robbed the house.Unless, the two deceased knew Xia Junqiang...Li Ang frowned and realized that things were not simple.
