It is definitely a very easy job to guard Ivan, because there is nothing to do, and then monitoring Ivan is definitely a chore because it will be really boring.

It was relaxed and boring and had to take responsibility, so it was thrown to the outskirts of Cape Town to guard the Great Ivan, which was definitely a good place to send a fugitive.

It is estimated that the task of guarding Ivan in the end will fall on Cia. After all, Cia has the most experience in doing such things.

If Cia is guarding Ivan, then Yang Yi will be much more relaxed. Why is it easier? Because he knows how Cia monitors an important target.

After first visiting the scene and looking at the local terrain, Yang Yi felt the idea.

"The manor of Ivan is on the flat ground. Cia will erect a pole and install a surveillance system to sit in the surveillance room to monitor Ivan's manor. The most effective surveillance method is the long-distance drone. As long as there are two, it can achieve 24-hour uninterrupted aerial reconnaissance. Well, for the sake of security, there will be at least four drones here."

Pointing to the sky, Yang Yi said softly: "At altitude that we cannot distinguish with the naked eye, there must be a small drone cruising. Anyone who enters and exits will be found, and then it can also be recorded. The only inconvenience is that the image is black and white, because the digital signal of the black and white image is smaller, and it transmits faster, and can be monitored in real time."

Grevatov frowned and said, "You mean we can't go in without being discovered?"

Yang Yi nodded and said, "Yes, it's basically like this."

Grevatov spread his hands and said, "It would be a bit troublesome if this is the case. I didn't expect Cia to use a drone to monitor it."

Yang Yi shrugged and smiled and said, "Wait, I have a way."

Yang Yi took out a cell phone.

"cell phone?"

"No, it's a mobile intelligence acceptance terminal... Uh, it's actually just a mobile phone, it's just a disguised as a mobile phone, but the function... OK, this is a mobile phone."

Yang Yi fiddled with it for a while, and then he began to try to enter the password and said, "The meaning of these drones is to transmit signals in real time, right? Then this drone needs to transmit signals to the ground, and I have permission to receive them. However, as long as I connect to the drone, I will leave traces. This is like a mobile phone connected to wifi, which will also expose my location while receiving signals."

Grevatov said in a deep voice: "No need to explain the principle."

"OK."

Yang Yi didn't plan to say that, but he couldn't help it, so he finally said: "My receiving terminal has been modified, don't forget that we have the best hackers."

"Hackers are hackers, and modifying hardware devices is not actually a good place for hackers."

"Well, we have hackers who are familiar with hardware, so I can receive signals without worrying about exposing myself, wait... OK!"

Yang Yi took the phone to Grevatov and looked at it, then he smiled and said, "Yes, there is a drone above us."

The drone is not big, but it doesn't need to be big, because modern sight-seeing and reconnaissance equipment can already be made very small, but it has powerful functions.

“There is also night vision mode…”

Grevatov felt a little embarrassed because on Yang Yi's mobile phone, the manor of Da Ivan was clearly displayed, and the huge open space around the building was also within the display range.

Yang Yi smiled and said, "First of all, this drone does not have a thermal imaging mode. Maybe there is a thermal imaging instrument, but it will definitely not be turned on, because the oil volume of the drone can support flying in the air for twelve hours, but the thermal imaging battery cannot be used for twelve hours. Therefore, if there is thermal imaging on the drone, there will only be three working modes, which will be turned on and off regularly, or will be turned on automatically after detecting a heat source. The last one, a controller will manually turn on after discovering an abnormality."

Grevatov said in a deep voice: "It is impossible to turn on automatically, so the second option and the first one should be the same, that is, the thermal imaging automatically turns on and off."

"I'm right, it will automatically turn on every once in a while. Scan and find the heat source and then focus on the heat source. But this is South Africa. There are many wild animals outside the outskirts of Cape Town. Also, Ivan is just under house arrest. This is surveillance rather than firing when the target is discovered. Therefore, there is only one possibility. Thermal imaging will not be used all the time. Instead, after a suspicious target is found, the drone controller will turn on manually."

"What do you want to express when you say so much?"

Yang Yi waved his hand and smiled, "It's nothing, I just want to say that this is easy to solve, well, let's go."

Grevatov followed Yang Yi and began to walk forward, and they needed to walk for a long time.

"Can you control the drone?"

Yang Yi nodded and said, "Yes."

Grevatov exhaled and said, "Why didn't you say it earlier?"

"Uh, I think you interrupted."

Grevatov raised his hand and said, "Wait a minute, why can you control this drone? Even if there are many devices in CIA that are universal, a task should have an independent password or other technical means to prevent any person from controlling their own devices, right?"

Yang Yi shrugged and said, "Well, I have the highest authority, I have the back door, and I can take over most of the control of the equipment. If I want to find someone, I will discover it. If I don't want to be discovered, no one can discover it."

"Why is this happening?"

Yang Yi sighed and said, "Because someone who appreciates me very much, well, I have some permissions that only the deputy director of the Free Cia can have, which is commonly known as the backdoor dog."

“What does the back door have to do with the dog?”

"It's okay, just a joke."

Grevatov suddenly frowned and said, "Wait, you just said that the Water Organization hacker modified your receiver? But now I don't think so."

Of course not. Yang Yi doesn't need to transform anything from others. The inheritance Aaron left him is more than a few words. Just as Yang Yi said, he now has some of the authority of Deputy Director Cia, which Aaron gave him.

"Well, just understand, you don't have to say it."

Yang Yi stopped and said, "It's time to get to the drone's reconnaissance range any further forward."

Grevatov looked at Yang Yi and said, "What are you going to solve it?"

Yang Yi smiled and said, "It's easy. If the drone loses its control signal, it will fly back automatically. When the people inside eliminate the fault or directly release the second drone, we have already entered."

Grevatov sighed and said, "I admit that I wanted to see what you have, but I didn't expect you to be the backdoor dog of Cia."
