At this moment, they were standing on the highest floor of this black and dark sky, Jiang Yanhai silently looked at the place below, the line of sight here was excellent, because there were no floors higher than it around, so it could see far away, and in the entire Golden Triangle Special Zone, there were not many floors higher than it.

After thinking about it, Jiang Yanhai didn't stay on the upper floor, but walked to the bottom, and after shaking it on the floor below, Jiang Yanhai walked to a wall at the back, "Come here and dig a pit." ”

"It's not...... What's going on here? This sniper can't be reached. "Red Fox is really a little confused.

"Whatever, anyway, we have a lot of things, so it doesn't matter if we bury one." Jiang Yanhai said quickly, and started directly while talking about him.

A hole was made in the wall, but instead of a bomb, an infrared surveillance camera was planted, and after the cement was pasted, only a small hole was left in the end.

The battery can last for about a month if it only maintains the infrared signal detection device, and of course, even less if you start shooting in the middle.

But there are basically no people here, and it can't be said that there is no one at all, and sometimes someone will come to these abandoned buildings with some kind of trade, but they will not climb to such a high place.

"Dig holes here." Jiang Yanhai pointed to a pit on the ground again and said.

The red fox and the bald eagle looked at each other, a little speechless, but they also began to dig the pit, although they didn't know why Jiang Yanhai had to dig a pit here, then dig it, now he is the boss He has the final say.

After planting the bomb here, this time camouflaged, swept the surrounding dust with the broom they brought, and then swept away their footprints, and they retreated.

When going down to the floor below, in some hidden locations, Jiang Yanhai also installed some solar-powered signal bridge relays.

It is enough to have this one.

When you wait until the first floor, you can barely connect with the nearby network signal base station, although the signal is not very good, but it should be enough to use.

"Why are we putting this place in place?" Red Fox was a little confused.

"Anyway, pretend to have a play, maybe there will be a surprise." Jiang Yanhai shrugged his shoulders. The bald eagle next to it is also a little puzzled, if it is a sniper, this place is too far, more than 3 kilometers away, unless the other party is to maintain a posture and do not move.

Otherwise, at least 4 seconds or more of the bullet flight speed, the enemy makes a slight movement, the bullet will not be able to hit, and there is no actual combat value at all.

If you can't hit it with one hit, the enemy won't come out again.

So, a location like this doesn't feel valuable. But no matter what they think, Jiang Yanhai planted a bomb here anyway, and life needs surprises.

The bombs outside were almost finished, and when they were done, they returned to the manor.

This time, Jiang Yanhai began to take them to plant bombs inside the manor.

"Why do we plant bombs on our own turf? In that case, what if one of our people stepped on it? "Red Fox felt like a retarded person.

"It's nothing, this place is very remote, it's impossible for our people to come over without anything, besides, if you step on it, you will step on it, this is not a mine, the kind that explodes when you step on it, this is a remote-controlled bomb, if you don't take the initiative to activate it, it won't explode." Jiang Yanhai shrugged his shoulders.

Red Fox: "......"

Forget it, we don't ask, you can do whatever you want. There are not a few buried in the manor, only three places are buried in total, these three places are still relatively remote places, according to the red fox and their opinion, even if the enemy attacks, these three places are not the best attack area.

After these three places were finished, Jiang Yanhai finally finished all the things, and he walked directly into the monitoring room.

In fact, there are different types of monitoring programs, for example, the most common monitoring programs, which are installed in all our stores, in fact, no one cares at all, most of the time, it is allowed to shoot and record there.

At most, something happened before they went to retrieve the content of the video surveillance and find the records inside, which is how most people use it.

However, some key companies and important bases are staring at some of the surveillance videos, and there are more important places where the surveillance video has professional monitoring programs.

These programs come with facial recognition, and the faces of anyone who enters the area are automatically compared to the faces in the database, and an alarm is immediately issued if a target person appears.

And Jiang Yanhai is doing this now, he is setting up the latest monitoring program, so that all the surveillance cameras are cross-compared, if a person keeps appearing within the scope of the surveillance camera, it will be highlighted, and then the police will be called.

Also, if a person is not found when he enters their monitoring range, and is found by the surveillance video inside when he enters a closer position to the core, it will also be highlighted, because if ordinary people walk normally, the monitoring of the periphery circle is absolutely impossible to avoid.

As for the monitoring inside the manor, it is set up separately, for example, all the people who enter and leave the manor, there is not much facial information of people who often come and go, and once a stranger sneaks in with makeup, he will immediately call the police.

It is not difficult to write such a program, and it doesn't even need to be written by Jiang Yanhai himself, Erdan can directly generate such a program. After all, the comparison algorithm in Erdan is more advanced, and it is very simple to make a matching algorithm that is not advanced.

But it looks like he has to install one, anyway, he doesn't have anything to do, Jiang Yanhai personally wrote this program, and then loaded and ran it, confirmed that there was no problem, and then secretly placed a virus into it.

The virus does nothing else, it doesn't strengthen the firewall that monitors the server, but it will alert you as soon as someone intrudes.

If you get a super firewall for such a server, it will be too fake, so as long as Jiang Yanhai knows what is going on.

With that done, it's a foolproof place.

In fact, the reason why Jiang Yanhai made these preparations was that Jiang Yanhai knew that the CIA would not give up, not to mention that one of their agents died here, even if it was because he was here, it is estimated that the CIA would do it.

I just don't know, will it be a killer or a squad that will come over next time?

Jiang Yanhai pondered that the probability that it should be a squad is relatively large, otherwise, with these people around Ma Yunfei now, it is estimated that it will be difficult for a killer to deal with it, after all, this squad has been assassinated once, and it is impossible for people to get close so easily.
