On the other hand, the various inferences of the Fifth Positive are basically reasonable guesses based on the premise that the criminal group is shrewd and capable.

Such an attitude just shows that the Fifth Zheng has never despised that group of ghost-like opponents.

Perhaps it was precisely because of this mentality that the moment the fifth saw Zhang Yun's abnormal behavior, he came up with the possibility that Zhang Yun was carrying explosives, and gave a timely warning.

Isn't this attitude of walking on thin ice anytime and anywhere exactly what he Cao Le should focus on?

It was only at this time that Cao Le began to formally face up to the Fifth Positive, and he became more attentive to the Fifth Positive.

"Okay, it's all up to you. Let's still think about how to find the traces of monitoring and installation in the house, maybe the monitoring of the criminal group does not need to drill holes in the wall, but only needs to be fixed with something.

Such traces are easy to remove, and it is easier to hide, and our move is likely to be fruitless. ”

Cao Le, who was aware of his own problems, changed his thinking and attitude very quickly, and immediately followed the Fifth Positive line of thought.

Regarding Cao Le's concern, the fifth positive has also thought about it for a long time. If you don't consider the clarity of the surveillance equipment, you don't necessarily need to do anything special to the translucent window, so that the traces left will be minimal.

But in the opinion of the fifth zheng, since the crime leader has set an overall plan to monitor the chasing soldiers behind Zhang Yun through monitoring equipment, it is just a matter of taking this opportunity to find out which policemen are tracking Zhang Yun.

In other words, if the criminal group wants to leave more clues, then the portrait information of the fifth person will be grasped by the criminal group.

Although the fifth positive does not necessarily understand what the consequences will be if his portrait features are mastered by the criminal group, he is still faintly uneasy about it.

After all, the criminal syndicate has created a big bang and their way of acting is dangerous and unpredictable, so it is unclear whether they will act against a specific police officer they know in order to deter the police at a critical moment.

What's more, if the characteristics of one's own portrait are mastered by the criminal group, then the actions after the Fifth Positive will be greatly affected, and it is very likely that the hidden members of the criminal group will be discovered during the visit.

Under such unfavorable circumstances, the investigation and visit process of the Fifth Positive will be greatly affected, and even misled into a very terrible way.

The enemy is in the dark, and I am in the light, which is the extremely unfavorable situation caused by the exposure of my own portrait.

Based on such an information advantage, the Fifth Zheng is absolutely willing to believe that the shrewd and abnormal crime leader will definitely take this opportunity to obtain clearer portrait characteristics of the police.

I don't know why, the fifth positive, whose mood suddenly became heavy, looked at the old door panel in front of him that blocked his way, and always had some unusually bad premonitions.

Picked up the lock and looked at it carefully, it did look a little bit old, and all the details showed that the lock had no traces of being opened.

As for whether it has been passive in the near future, it is still necessary to conduct a detailed inspection of the lock cylinder to judge. Without the slightest hesitation, the fifth Zheng directly picked up the tool next to him and easily removed the metal knocker that fixed the lock.

"This lock is sent to the laboratory to test the cylinder to see if it has been moved."

If Crime Member 2 enters and exits through this door, then no matter how perfect the appearance of this lock is, the lock cylinder inside must have traces of wear and tear by the key, especially this rusty lock, the metal oxide layer inside must be very obvious.

"Do you want to test now? So are we going to wait until the results come from the lab before we go into a careful search? ”

Cao Le put the lock and door knocker he received into the evidence bag and asked about the next course of action.

"No, I don't. Even if the lock passes, it only proves that criminal member 2 has been here.

Whether there is a surveillance installed in it or not can be judged by the specific traces left behind. In addition, dust accumulates in the room, and footprints and other traces of activity are more likely to be left behind.

These clues, regardless of whether the lock is identified or not, can be entered and collected in advance. ”

The fifth one, who didn't look back, quietly stared at the dim room where the dust was slowly rising, and explained in a flat tone.

The fifth is not entering, Cao Le does not dare to enter rashly, besides, the interior of this cramped bungalow, there are no obvious footprints at first glance, and the sundries in the room are placed at random, and it does not seem to have been deliberately moved.

I don't know how many years of this old house has been sealed in the dust, and it doesn't look like someone has just been here.

Cao Le, who silently followed behind for a long time, did not find anything unusual, and saw that the fifth Zheng in front of him had no intention of entering, and he also seemed a little puzzled.

Is it really necessary to observe this old hall at a glance for so long?

"Fifth, do you see any valuable clues in it? Or maybe you're trying to find some hidden mechanism in this room? ”

Cao Le asked weakly, his eyes constantly moving back and forth between the Fifth Positive and the hall, as if he wanted to find some clues from the Fifth Positive's face.

"Someone walking through a dusty place like this is bound to leave footprints.

You say, who else but a flying man can pass through this hall without leaving a trace? ”

Cao Le didn't see any flaws, and when he was asked by the fifth Zheng, he could only pout, saying that he didn't know.

"Who knows, there are no legged ghosts that can fly except winged birds and insects.

Do you think those people can still hang a tightrope here? If you have this leisure, you might as well clean up the dust here. ”

Although he has no goods in his heart, Cao Le's ability to find words without words is still quite strong, and he will open his mouth after a few crooked reasons.

"If you want to leave no traces, you can hide them in addition to not making traces yourself.

The most common is to use old objects in this house, or old objects moved from other places, to hide the footprints that pass by.

In this way, large objects will cause the room to be covered with dust again, and the traces of small objects will be limited, so it is very difficult.

Secondly, it is to pass through the top of the beam or in the air with the help of hanging wires.

In this way, it is not necessary to install WIA equipment in advance, but only need to use hook locks and certain climbing skills to pass through well.

The most sensible way to do this is to pass through the ground, but the traces of passing will be controlled within a very small range. ”

For this somewhat unreliable Cao Le, the fifth is feeling that he only gives people such a feeling because of his personality, at least, he also gives the possibility of passing through the air with the help of equipment.

Hearing this kind of hint from the Fifth Positive, Cao Le hurriedly glanced at the narrow hall again, but still didn't find any clues.

"You're saying that Crime Member 2 did pass through here, but we didn't find any traces of him?"

"Yes. Sweep the footprint lamp to the ground and you'll find some clues. ”

Under the guidance of the fifth positive, Cao Le took the footprint lamp and swept it on the ground very interestingly, and immediately found some subtle raised traces.

This dense and subtle protrusion is like someone who has eaten enough and has nothing to do, playing with a steel needle on the ground.

Seeing this obvious clue, Cao Le's heart was also excited, and he hurriedly shone the footprint lamp into the distance, and immediately found a path that winded inward.

There are indeed footprints! Crime member No. 2 once passed by here wearing steel spikes!

When a person sees no obvious footprints in a dusty room, they assume that no one has ever been to this room, and using this habitual mental inertia is the core trick of Crime Member 2 at this time.

Fortunately, they have footprint lights in their hands, otherwise in the case of casting a wide net to search this demolition area, everyone would be in a hurry, and it would be really easy to be concealed from the past.

"Holy, I'm wearing spiked shoes! If there is such good equipment, why do you still leave such obvious footprints elsewhere?

Could it be that the trails we have collected are really just a series of false clues to divert our attention? ”

After recognizing this obvious clue, Cao Le finally felt a little convinced of the various speculations before the Fifth Positive.

Facing one's opponents with the most rigorous attitude is not only a kind of respect for one's own work, but also the greatest responsibility to all one's colleagues.

"Such a cautious move is just a small trick done by the crime boss to prevent the police from finding a large number of traces left here when they searched the houses near Zhang Yun's supply site.

In this way, the fact that the criminal organization has installed surveillance here will be completely exposed.

This cautious style is very much in line with the style of a crime boss.

As for why Criminal Member 2 left a series of obvious footprints in the subsequent process, it is largely because he knows that he has been exposed, and there is no need to continue to hide the traces.

As for the possibility of leaving false traces, although it still cannot be ruled out, the possibility is much smaller.

Take a picture of the traces here, we have more to confirm. ”

For Cao Le, it can be said that there are questions and answers, and the answers are quite smooth, which makes Cao Le truly realize the rigor of the fifth positive thinking.
