The reason why he asked Ye Chen and Lang Hongjun to call home first was because his car was equipped with signal shielding equipment. Once the car left the city, he would turn on the shielding equipment to prevent the signal base station from recording
The movements of the two people’s mobile phones.
Because all mobile phone communications rely on ground base stations, and a large number of ground base stations overlap and cover each other, forming a communication range with almost no blind spots in the city. The mobile phone will automatically adapt to the one with the strongest and best signal among multiple base stations.
Then establish a connection with it.
When the mobile phone continues to move across regions, the mobile phone will search for the base station with the best signal and continuously switch between multiple base stations. In this way, the base station will also record the access information of this device.
If you want to use a mobile phone to track a person's movement track, you only need to call up the access time and specific information of his mobile phone and the base station, and you will be able to lock in a relatively accurate route map and a relatively precise range.
In this way, the specific location of the criminals' lair will be exposed.
Therefore, this young man just deliberately falsely claimed that Mexico's infrastructure is not good, in order to pave the way for the next step of blocking the signal.
With this early vaccination, when the two of them find that there is no signal on their mobile phones, they will definitely not feel anything unusual.
After the pickup truck left the airport, it headed south. When the truck was about ten kilometers away, the young man quietly reached out and touched under the passenger seat and turned on a hidden switch inside.
This switch is the power supply switch for the signal shielding device.
After pressing it, all signals within five meters of the car will be completely blocked. Not only can't you make or receive calls, you can't even receive satellite signals.
Lang Hongjun chatted with Ye Chen all the way, and at the same time chatted with his wife on WeChat on his mobile phone. But while chatting, the mobile phone signal suddenly became unavailable. He was a little surprised, and subconsciously said: "Ouch, there is no network so soon.
Already..."
The young man laughed casually and said, "Hey, this is so normal in Mexico. In places like Mexico, as long as you leave the city, there is basically no signal for your mobile phone."
Lang Hongjun nodded slightly, then put down the phone, looked at the desolate desert-like landscape outside the window, and asked Ye Chen: "Brother, when you came to Mexico from the United States, did you feel the gap? Look outside.
The wilderness is not much different from no man's land."
Ye Chen smiled and said: "I am actually very adaptable. If you ask me to stay in the presidential suite of a five-star hotel today, I won't be excited. If you ask me to set up a tent in the wilderness tomorrow,
I don’t feel uncomfortable living in the open air.”
Lang Hongjun smiled and said: "You have a good personality. Your personality is a standard optimist. You can adapt to wherever you go as quickly as possible."
"Yes." Ye Chen nodded and said with a smile: "I have lived through all these years. I don't dare to say that I am well-informed, but at least I can be indifferent to favors and insults."
Lang Hongjun gave a thumbs up and praised: "I wish I could be as free and easy as you."
As he spoke, he glanced into the distance. When he vaguely saw something in the distant wilderness, his brows suddenly frowned.
Immediately, he subconsciously picked up the phone and fiddled with it, his expression became more solemn and even a little nervous.
Ye Chen noticed Lang Hongjun's change with his peripheral vision. He also saw Lang Hongjun carefully looking at the Mexican driving the car, and he couldn't help thinking to himself: "Is this Lang Hongjun discovering some clues?"
Just as he was thinking about this, Lang Hongjun picked up his phone, pressed it for a while, handed it to Ye Chen, and said with a smile: "Brother, let me show you a photo of my son. He is so handsome."
Ye Chen lowered his head and saw that there were no photos at all on the screen of the mobile phone he handed over, but a line of text: "Brother, there is something wrong with this kid! We may have been fooled!"
