Through navigation, ride an electric donkey and quickly shuttle through the bustling streets of Suzhou City. Penguin's Suzhou branch is located in the Dongfang Tianmen business district, not too far from Wang Lan's Xinyu Building.

While chatting with Jiang Xinyu, Wang Lan suddenly realized a loophole in the monitoring network of the Heavenly Sword Bureau. The Heavenly Sword Bureau only listened to Chang Yu's phone and the people Chang Yu came into contact with, but what era is it now? Now is the information age, the Internet age.

In the age of the Internet, there are more contacts between spies and spies. What websites are you on, what posts you visit, who you contact, and what remarks you make.

Even the connection is not necessarily interactive.

Can Chang Yu not take the initiative to contact, but passively accept? If she passively accepts, then the channels through which she can obtain information will be too great. Open a post bar and watch someone else's post to get instructions from a specific post.

And now Yuguo's network is almost a monopoly of Penguin. This is also the reason why Wang Lan went to Penguin. The broadband used is Penguin's, the search engine is Penguin's, and even the chat tools are Penguin's.

Arriving at the entrance of Penguin, the lights are still bright in the 15-story independent office building of Penguin.

"Hello sir, may I ask you what's the matter?" the security guard at the door stopped Wang Lan.

Wang Lan didn't say a word, and took out the documents of the Heavenly Sword Bureau, "The Heavenly Sword Bureau investigates, please contact the person in charge of the branch of the Suzhou Penguin Company, thank you." ”

For the people of the Jade Kingdom, they may not have seen the warriors of the Heavenly Sword Bureau, but it is absolutely impossible that they have not heard of the prestige of the Heavenly Sword Bureau. Whether it is on the Internet or in the mouths of ordinary people, there are many stalks about the Heavenly Sword Bureau.

Those who are in awe call them agents, and those who are not in awe call them relevant departments. Anyway, the door-to-door water meter in the mouth of the joker basically refers to the Heavenly Sword Bureau.

The doorman's face changed suddenly, and after carefully looking at Wang Lan's work card, he hurriedly called. After a while, a middle-aged man with a big belly and a Mediterranean hairstyle hurriedly walked in the reception hall of the office building.

"May I ask if you are the head of the Heavenly Sword Bureau?"

"You're the head of Penguin?"

"I'm the CEO of the Sioux City Branch, and the chief is please. Excuse me, is there something that our Penguin Company has offended?" asked the CEO cautiously as he led the way.

Although I may usually use the Heavenly Sword Bureau to open the brush, when I was really checked the water meter, I was very panicked in my heart. Moreover, the most common trivial thing is the door-to-door visit of the guard. It is not a small matter that can alarm the Heavenly Sword Bureau to come to the door.

"No, I need Penguin to help me look into some information. After all, Penguin's cloud has almost everyone's data, so isn't that embarrassing you?"

"Don't be embarrassed, don't be embarrassed. The middle-aged man hurriedly agreed. As long as it's not the company's fault, he is relieved. The waist pole is also straightened, and the voice of the voice is naturally relaxed.

"It's so late, and your employees are still working overtime?"

"Aren't all programmers at this time? That's the state of existence in this line. Chief, please. ”

"Don't be a chief, I'm not used to hearing it, my name is Wang Lan, you can just call me Wang Lan. Don't call Xiao Wang, don't add modal words after it. ”

"Hahaha...... The Wang Lan brothers are quite funny. Here, please, here is our data analytics department. The role is to analyze the data traffic and adjust the distribution of the traffic.

By the way, the user's interest push is also responsible here. Basically, the data aggregate on the network flows here. Old building, come over for a moment. ”

In the office, a middle-aged man who was also from the Mediterranean stood up and ran, "Mr. Jin, you call me." ”

"This is Wang Lan, the head of the Heavenly Sword Bureau, and he wants you to cooperate with him in his investigation. If he has any request, you should cooperate, stop what you are doing, and don't rush for a while. ”

"Okay, good chief Wang. ”

"Hello Mr. Lou, just call me Wang Lan. I hope you can extract a person's network data for the last six months. Chang Yu, ID number *********, mobile phone number *******"

"Okay, wait a minute!"

Wang Lan sat next to Mr. Lou, and saw his fingers flying, as fast as lightning on the keyboard. After a while, the progress bar began to leap forward. After waiting for half an hour, the data was downloaded.

"That's it!"

"How has she been active online in the past six months?"

"It's sluggish, there's almost no activity. Looking at the identity age of only twenty-four years old, like a girl of this age, generally speaking, a week's traffic is worth half a year's traffic. ”

"Was her previous traffic like this?"

"This ...... I'll look it up. ”

It was another crackling operation, and the results came out in about ten minutes.

He started to see a plummeting in data usage in March, when her data consumption levels were almost average. After that, she seems to rarely surf the Internet, and her main traffic consumption in the past six months has been downloading ten movies to watch. ”

"She often goes to the post bar, and the website sorted it out for me. ”

"Okay, well, her preferences are a little unique, a girl likes to log on to military forums and check the data on the website of the National Bureau of Statistics. This is something that military fans generally pay attention to only in social sciences. ”

"Give me a computer and I need to see what she's been looking at. ”

Wang Lan was next to Minister Lou, and used her notebook to read all the websites that Chang Yu had browsed one by one. Fortunately, Chang Yu didn't watch much, but it took Wang Lan two hours to finish reading.

"Since she started in March, has she ever interacted with anyone online?"

"Yes! She has interaction on the Penguin. But they are all blessing text messages, and there are some reprint text messages. She hardly posts news and does not speak on the Internet......

This man...... It's so withdrawn, it's hard to believe that it's such a beautiful girl. Generally, middle-aged and elderly people who can't access the Internet are in this state. ”

"Can you stealthily land on her Penguin? I want to see what she interacts with, and who she's interacting with. ”

"Okay. I sync to your computer. Minister Lou said while operating quickly, and soon, Wang Lan's computer popped up with the penguin interface of a web bar.

"I'll list my nearest contacts......"

In the past seven months, Chang Yu's external contacts can be described as the extreme. I almost don't chat with people online, I don't post news, I don't talk about it, I don't feel emotional.

It seems that she lived in the previous era, and she was out of step with this era.

The first few contacts should be her suitors, some invite her to dinner, and some invite her to play. But there was no reply to all of them. A person who was forced by Chang Yu's cold attitude sent a question, and he was blocked before he said a word.

Wang Lan can only say, count your fate. Chang Yu is going to agree, I'm afraid you are not far from death.

As he flipped down, a contact suddenly caught Wang Lan's eye.

This contact person sent Chang Yu an advertising message, an advertisement, with a long story of at least more than 1,000 words. A lot of the content is still repetitive.

There are more than a dozen such advertisements, all of which are sent by the other party. Chang Yu ignored it and didn't block it. But this point made Wang Lan suspicious.

How can a normal person endure such a long-winded advertisement? How can he accept so much when he sees the first one?

And the advertisements in these fragments are also mixed with some meaningless numbers. A number is neither a number, nor is it a verification or anything.

"Find out when this person became friends with Chang Yu. ”

"Yes, April 1st. ”

"April? is it after Chang Yu's usage traffic plummeted?"

"Yes!"

"Who added it on their own initiative?"

"The other party added it, Chang Yu passed. ”

"Secretly log in to this person's account in the background!" Wang Lan's eyes flashed, and he hurriedly said.

"Okay!"

After a while, a web version of the Penguin appeared on Wang Lan's computer again. And in this penguin, there are even fewer friends. Thirty friends, and only twelve contacts in the last six months.

Wang Lan clicked on the other party's dialogue interface, and all of them were sending advertising messages to those people. And none of these twelve people blocked this number.

"The Penguin that secretly landed on these twelve people!"

"Okay!"

"Check the network traffic usage status of these twelve people, is it almost a stand-alone machine like Chang Yu?"

Minister Lou was very excited right now, he had a gut feeling that he was doing something very exciting and great right now. It's like decrypting layer by layer, peeling off a certain veil of mystery layer by layer.

Although, until now, he didn't know what Wang Lan was investigating, but he just had this kind of intuition.

"Little brother Wang Lan, you guessed right. All of these twelve people have almost no traffic. But the time varies, the most recent one started two months ago, and the oldest one has barely been online since last year. ”

"Check the direction of their traffic usage, and whether they have anything in common with Chang Yu. ”

They are all very concerned about the military and current affairs, and they basically look at the country's dynamics on the Internet, and what new weapons have appeared in the army. ”

"It seems right!" At this point, Wang Lan was almost sure, and his guesses in a flash of inspiration had all been confirmed.

I took out my phone and dialed the phone number.

"Hey, King!"

"Wang Lan, what time is it...... What's the matter?"

"I might have found them. ”

"Find them?who?"

"Chang Yu's demon spy team. ”

"Bang-"

On the other end of the phone, there was a muffled ring. Then the sound of an inhalation was tooth-aching.

"Wang, are you alright?"

"Do you say it again, what have you found?" the voice of the other Wang Qianfeng suddenly burst out.

"I said that I might have found the identity of Chang Yu's demon spy team. ”

"Where are you now?"

"A division of Sioux Penguin. ”

"Don't go anywhere, I'll be there in a minute. ”

After hanging up the phone, Wang Lan continued to study the information of these twelve people. The real identity of the person who sent the message to Chang Yu is also easy to find through account tracing, his name is Qin Jiaqing, male, 60 years old. From the analysis of the data flow, this Qin Jiaqing should be the leader of the fourteen-person group.

He gave instructions to the rest of the people by sending advertising text messages, although these short messages had not yet been deciphered, Wang Lan believed that it should not be difficult for the Heavenly Sword Bureau.

The rest are men and women, and their identities are completely unassociable. Some are chefs, some are programmers, some are engineers, and so on.
