Because this guy starts to appear in the lower left corner of the door line, but walks out in the bottom right corner of the door line. In the case of normal walking is completely unnecessary.

After all, if your purpose is to walk out in the bottom right corner. From the very beginning, you can completely walk directly from the "mouth" shape, the bottom side. Why do you have to go around in circles?

Although this guy in gray clothes, in the upper right corner, bought a pack of cigarettes and also bought an evening newspaper. But Hua Zhang didn't believe it, this kid couldn't buy cigarettes and newspapers anywhere else. Why do you just go around and buy it in the upper right corner of the Finance Building?

The person at the surveillance point immediately began to make phone calls, and immediately described the characteristics of this person wearing gray clothes, holding a brown briefcase, wearing a black top hat, face shape, approximate age, etc., to the mobile team. Including in which direction the person went, and on what street it was immediately said.

The mobile team immediately dispatched two experts who were good at tracking, rode bicycles, and immediately came to the relevant streets. According to the characteristics, it was quickly embellished with a guy in gray clothes.

After all, after this kid observed the financial building, it was impossible for him to run away immediately. If you do, you will expose yourself.

It was this suspicious guy in gray clothes, still walking at a normal pace. It's the same, it didn't take long for it to be embellished by the people of the mobile group.

The reason why these two tracking agents of the Security Bureau can be called tracking masters is that they are indeed very capable in this regard. Seeing that the target was not riding a bicycle, the two of them immediately stopped riding.

Instead, he got out of the car, blended in the crowd about thirty meters away, and pushed the car, as if he was chatting about his boss's gossip to disguise, while blocking the vertical line of sight with the flow of people in front of him. And their gaze is only to use the edge of the body of the person in front of them, or the shoulder, to pass through and stare at their target.

In this way, even if the target suddenly looks back, then the figure of himself and others is hidden behind the flow of people. This makes it difficult for the people in front of you to find out.

The turning point came a dozen minutes later. During the ten-minute tracking process, the tracking masters of the two security bureaus, the more they followed, the more they felt that the other party was really a professional.

Because, in the process of about ten minutes, no matter where the target person wants to go, they all feel that the other party should have gone far away when he appeared in the Finance Building. And now, as long as it is far away, the suspicion will naturally increase.

But so far, it's only a big suspicion. Not very sure. After all, the other party didn't even look back once along the way.

And the next moment, the two security bureau stalking masters. As he entered a street again, it wasn't far away. Suddenly, the kid turned a corner and entered a grocery store on the side of the street.

Luckily, this time the Security Bureau was following two stalkers, and they used phishing tracking. What does that mean, when the target enters a street, you don't go in first, but you come to the corner of the street, and then you observe the target until the target turns again, or enters another street, and you are moving quickly. Again, look at the target. In this way, you can minimize the amount of time you spend in the other person's line of sight.

It is precisely because of this that these two tracking masters were not exposed. Otherwise, even if they are some distance away from the target, if they follow, they will probably appear in the target's field of vision. Because it depends on the target of wearing gray clothes, it didn't take long for him to come out of the grocery store again.

And this kid stood at the door of the grocery store, took out the cigarette case, and unhurriedly lit a cigarette for himself. If you look at this move at ordinary times, it is really not a problem at all. But for the stalkers of the two security bureaus, it is completely different.

In the previous ten minutes, they had followed this kid to this place. In combination with the location of the finance building, the tracking masters of the two security bureaus felt that this guy must have gone far away. Therefore, the suspicion is also great. And when you get here, you suddenly come out like this, what does it mean?

The two stalkers were happy when they saw him move. Why? Because combined with the previous situation, the action of this kid in gray clothes now lighting a cigarette in front of the grocery store is almost 100% sure that it is an anti-tracking action. This kid is using this action to observe the situation behind him.

I have to say that this kid's anti-tracking action is still a bit level.

Because he had been walking normally before, and then after walking this road, when he passed by the grocery store, he made a very sudden turn and entered the store.

At this time, if there is a person following behind, he will definitely be surprised psychologically, and even think that this kid has arrived at his destination. Or a little hesitation, it's all possible.

But the next moment, the guy suddenly came out again, adding a cigarette, very reasonable move, to observe behind him. In this case, if there is a tail behind it, it is very likely to be found.

Fortunately, the two agents of the Security Bureau are not good at stubble, and the tracking method used is very special, so they did not let the other party find out. And also found out the other party's anti-tracking action, and immediately determined that the other party must be a professional. Otherwise, would ordinary people have this kind of professional anti-tracking technology? Impossible.

Next, the agents of the two Security Bureaus were more careful. Because the other party made an anti-tracking action, does this mean that this kid is about to enter the destination?

Sure enough, the two followers followed this kid and soon came to a very lively street, where they were all doing business next to the road, as if they were evening markets.

The guy in gray clothes bought a paper bag of food here. Then he walked two more streets, even nodding to a pedestrian on the road, then took out the key from his pocket and calmly entered a bungalow with a small courtyard.

The two tracking masters of the Security Bureau did not dare to be careless, for fear that this was the guy's transit point, not his address. So the two people then separated, one in the front street, the other in the back street, guarded for a while, and found that this kid really didn't come out, and then it was determined that the bungalow with a yard was the other party's "home".

So one person was left to watch, and another agent immediately rode to another street, found a pay phone, and reported to Huazhang......
