Jiang Fan immediately got up and came to the notebook.

On the screen, the path where the video is located is displayed, and Jiang Fan clicks it, and the video will automatically pop up.

Two vans move off the screen into the distance.

But because the camera's field of vision is limited, Jiang Fan can only guess an approximate location.

After guessing the location, Jiang Fan looked for the drawing software on his mobile phone, and drew a few routes they might take in the drawing software, and after guessing the route, the next search would be more convenient.

Soon, the software automatically searched for the two vans for Jiang Fan.

After about a few cameras, the two vans suddenly turned into one van, and Jiang Fan quickly checked the video, but the second van never appeared.

After about a few more cameras, Jiang Fan could no longer find any trace of these two vans in the surrounding cameras.

Wang Liudao, who was watching from the sidelines, said, "Can't you find them?" ”

Jiang Fan nodded slightly and said, "Hmm." ”

"Is there anything else we can do?"

Jiang Fan took out his mobile phone, opened the mobile phone map software again, and said, "This is the only way we can now." ”

"Maps?"

"Yes, it's a stupid idea, but that's the only way we can do it."

"These people obviously planned their escape routes, and when they escaped, they were very calm, and after a few intersections, they bypassed the cameras by taking small paths, which are the paths that they were able to bypass the cameras."

"When they get into the path, we have to do a lot of analysis because the road is connected to a lot of places, there are many forks, and they can drive in any side of the road to get around the camera."

"What we need to do is map out all their possibilities and calculate which monitored intersection they'll pass through based on those routes."

"Because no matter how much they try to get around the cameras, there will be cameras at key intersections, and as long as they want to move over long distances, then they have to go through certain intersections, and these are the only ways for them to go."

Wang Liu nodded, and Jiang Fan continued: "Let's start with the nearby villages, the sections marked by me on the map are the sections where they disappeared. ”

"As for the van that disappeared in the end, we don't have to worry about it now, we just need to find any of them, and the rest will gradually surface."

"Good!"

Wang Liu also turned on his mobile phone and began to search quickly.

Jiang Fan continued: "According to my current speculation, the location of those people should be relatively fixed, and according to the information I found, there are cameras on every way out of the market, so it is impossible for them to rush out of the market." ”

"Seeing their images from the cameras at various intersections, these people should be trying to go around in circles with us, that is, these people may not have left the city! And a few areas where those people might have been haunted have been speculated. ”

"Figured it out so quickly?!" Wang Liu's eyes lit up.

Jiang Fan nodded and said, "What I am most sure of is that they are absolutely not out of this city now, as long as they are not out of this city, we will be easy to find." ”

"To find these people, we first need to know them, as long as we know them."

"Why do these people abduct and sell children? In order to let these children bring benefits to them, and these children do not know any technology, so how can they bring benefits? ”

Wang Liu suddenly realized.

Professional is worthy of being professional, what Jiang Fan thinks is not on the same line as what she thinks.

Jiang Fan said again: "So where they are, the number of people must not be small, and there must be many people coming and going, and most of the people cannot be locals every day." ”

"Because most of the people who move every day are locals, these children are easy to remember, and they are known by the locals that these children have been asking for money on the street, and those locals will definitely be suspicious, so the best place is next to the scenic spot, and the scenic spot will come every day with a lot of foreign tourists."

"There are many scenic spots in the city where we are now, and some of them are attractions to be developed, according to my search yesterday, there are still two attractions under construction, and there is a small county near one of the attractions, although the development of the county is not very good, but because of that scenic spot, the future development will not be bad."

"And that attraction has a relatively high popularity on the Internet, so if those people don't go out of the city, they will probably be here, but there are other places that may be their new foothold."

Sometimes, you have to use your brain.

Although Jiang Fan's hacking skills are very powerful, his computer cannot hack so many cameras at the same time, and constantly use the computer to scan suspicious vehicles while hacking so many cameras.

Moreover, those cars are very good at putting on the license plate numbers of other vehicles, and at that time, Jiang Fan's workload will be doubled.

Once the time is a little longer, what they are looking for is not this license plate number, they are looking for this model of van.

After Jiang Fan finished telling Wang Liu, he planned to turn around and leave.

Wang Liu stepped forward and stopped Jiang Fan and said, "What are you going to do again?" ”

Jiang Fan glanced at Wang Liu and said, "I'll go outside to search for clues, and when the two children fall asleep, let Xiaoxuan and them help you." ”

After speaking, Jiang Fan turned around and left.

Wang Liu also knew that she herself would definitely not be able to persuade Jiang Fan, she could only pray silently for Jiang Fan in her heart, wishing Jiang Fan all the best.

On the way out, Jiang Fan actually felt a little stupid in his heart.

At the beginning, Jiang Fan thought that all his actions were very rational, but after thinking about it carefully, at that time, he only cared about rescuing Jiang Xiaoxuan, and forgot how to deal with the follow-up actions.

What's more, these people are even more cunning than Jiang Fan imagined.

If there are monkeys in the follow-up action, Li Si and their confessions, Jiang Fan's actions will be much smoother.

At the very least, Jiang Fan can roughly draw what those people look like through the mouths of the two of them, as long as he knows what they look like, Jiang Fan can further investigate.

It's not that far from that abandoned alley.

If nothing else, it is estimated that Li Si and Monkey should still be in the abandoned house in that alley, after all, these two people have been scrapped by Jiang Fan and cannot move, although they have lost the ability to stand up for a long time.

It's even more unrealistic to climb out.

Once they climb out, they get a lot of attention, and once they do, they get to the hospital.

If they are sent to the hospital, it will be troublesome, although they may be rescued, but what awaits them is likely to be the death penalty.

"Monkey ...... Otherwise, let's go out and turn ourselves in. ”
