"Director Li, I'll give you twenty minutes, can you find out which one of them is Wanyi's doll? Everyone just took advantage of this time to finish their meal."

Meng Fei handed over the last key task to Li Huo.

"No need for twenty minutes, give me ten minutes!"

Li Huo finally got a chance to perform, so of course he would not let it go. He immediately called his subordinates.

This last step is not difficult. Among the remaining four people, Wanyi's doll must have lost contact after entering the country.

As long as we try to contact them, if we are lucky, three of them can be contacted or their whereabouts can be determined, and the remaining missing ones are Wanyi's dolls.

Of course, the worst thing is that none of the four people can be found. Then investigators can only be sent to search for the whereabouts of these four people, which will take more time.

In just three minutes, Li Huo's cell phone rang. After answering the call, he picked up the laser pointer and pointed it at one of the four red-black women.

"This is the only one who has lost contact. It should be her."

"Well, her?"

Meng Fei looked at the information displayed on the screen.

"The entry time is February 4, 2022.

"Wanyi complained to Cloud Leopard Entertainment about the bug in Twelve Hour Nightmare on January 10."

The two times are one after the other, about half a month apart. It seems that the conclusion is correct.

It's just that the red-black woman in the information has a very round face and a darker complexion. From the appearance, she is typically dark and short, far less smooth than Wanyi.

But it’s not difficult to explain. The dolls deliberately use ordinary looks that don’t attract attention to get on the plane and go through customs. This is of great benefit, because beautiful women always make some people look at them more, increasing the chance of exposure.

"Even if this guy is Wanyi's doll, what can we do?"

Li Huo still didn't understand Meng Fei's intention.

"Goddess, please play the video surveillance footage of her entering the country." Meng Fei entered text on his mobile phone.

"OK."

A picture of the arrival hall of Wutong Airport appeared on the screen. A thin and unattractive woman was outlined in a red frame.

She was alone, with no companions and no luggage. She only had a small bag on her body.

"Using the original mobile phone card to communicate directly after entering the country will be very expensive and not cost-effective, and it is also easy to expose their own information.

"As long as they are not frequent travelers between the two countries, most people will prepare a mobile phone card for the destination country and activate it when entering the country.

"Most temporary mobile phone cards in Qingmang are not activated automatically. After inserting the card, you need to dial a phone number.

"If you see in the video that she used her mobile phone to make a call for the first time, and she only listened to the phone prompts and pressed buttons without speaking, then she was probably activating the mobile phone card."

Meng Fei carefully moved the surveillance screen forward while paying attention to the actions of the other party on the screen. Everything was as he expected.

After filling out the information and entering the country, when she walked to the airport aisle, she made a phone call for the first time!

The exact time is 1:30:20 pm on February 4, 8022!

"Goddess, please help me find the communication base station closest to this surveillance screen, and find out the information requesting activation of the mobile phone card sent through this base station at this point in time."

There are many people entering the country at this point, and many people activating their mobile phone cards. But if you specify a time point and a designated base station, the range will be very small.

"A suspicious mobile phone number has been found."

The goddess displayed the suspicious mobile phone number on the big screen.

"Show me the call history so far?"

What Meng Fei is most worried about is that the puppet sister's newly activated number will be discarded and then changed within a few days, and his plan will be completely wiped out.

But he thinks this probability is very low. Because the mobile phone card prepared by the doll in advance should consider itself safe enough and there is no chance of being discovered.

Even if it is discarded, some valuable information should be found from the call records before discarding.

"This is a pure data card. It does not have the function of calling other mobile phones. The only call is to activate the card.

"But the data traffic has been used in the past six months. Until yesterday."

The goddess replied.

"Until yesterday?"

Meng Fei's sensitive brain nerves were touched.

"Show the location of the base station this mobile phone number has connected to!"

Meng Fei felt that he had finally grasped the key point, his heart was pounding, and his eyes were fixed on the screen.

Other people in the conference room couldn't move their eyes away. Fatty Chen's last half of the French fries fell out of his mouth.

"OK."

The map of Wutong City was displayed tiled on the screen. Then red dots were marked one after another.

The first red dot appeared at the airport, then on the way from the airport. It was winding and winding, and finally stopped at Songdu Road Snack Street!

Real hammer, real hammer no doubt.

This is the mobile phone number used by the Wanyi doll, and it has finally been found. Now let’s see how many clues we can dig out from the usage records of this mobile phone number.

The data card only has network traffic and can only be used to surf the Internet. Chiwu people are accustomed to using email a lot, and the most popular instant messaging app is "Lai Press".

But unfortunately Lai Press is banned in Qingmang’s country. What app will she use instead? Will she use WeChat?

"Show apps she has used."

Almost all apps nowadays are connected to the Internet. Different apps have different marks when they use network traffic, and operators have records.

"There is only one app she has ever used. It is a mobile game operated abroad called Global Terror."

"Mobile game?"

"right."

If it was a game, Meng Fei could roughly guess what was going on.

He had heard similar stories in the news in his previous life.

A certain country monitors the Internet and phone calls all over the world, making it almost impossible for terrorists to communicate through normal means. In the end, it was discovered that they used Sony's PS2 game console in an ingenious way.

Many games have networking capabilities, so teammates can chat with each other. And even if there is monitoring, discussing kidnapping, planting bombs, explosions, etc. in a gun game will not attract any attention.

But for Meng Fei, it would be beneficial to him if they used mobile games to communicate.

Instant messaging software will implement a strict privacy policy and no chat records will be saved on the server.

But this is not necessarily the case in game play. Mutual conversations between teammates may be saved as part of the game log.

Meng Fei turned off his phone and put it back in his pocket, then grabbed Li Huo's laptop and started working on it.

Because his mobile phone's screen mirroring was gone, the laptop's desktop was once again exposed on the screen.

And Meng Fei openly searched the homepage of "Global Terror" and then started to crack it.

"Global Terror" is a game on the surface with a "anti-terrorism" theme, but in fact it is about experiencing the thrill of terrorism.

One player is responsible for counter-terrorism, while the other player is trying their best to create terrorist incidents.
