Police Detective

Finding a place nearby that could conceal the heat source, Ren Xu arranged for everyone to rest there, and then covered some branches outside. Ren Xu began to recall in his mind all the places he had passed in the past few days.

The opponent has a master.

What it means to be an expert is that the opponent must have the ability to avoid thermal imaging or.

Or the other party also has a thermal imager! Even more accurate!

The fundamental imaging of a thermal imager lies in the temperature difference. At present, the outside temperature at night tends to be 16 degrees Celsius, which is 20 degrees different from the human body. The thermal imager is a bright light under the action of the thermal imager.

Some people will lower their body surface temperature by smearing mud on their bodies, but this is only temporary. The human body is a large heat source and can quickly heat the mud to the body surface temperature.

Therefore, the better way to protect the thermal imaging camera is to cover it or wear some special clothes that block a certain amount of heat radiation, such as firefighters' clothes.

But this still doesn't work. If this type of clothing is walking through the mountains and forests, the thermal imaging camera may not be able to see it, but it will shine like silver.

Someone said, why don't you put on a layer of sparkling silver firefighter clothing first, and then put something else on top?

no

This outer layer can block a certain amount of thermal radiation, but it cannot block heat conduction. The human body will still heat the jacket, making it detectable.

Shading is effective, but in addition, it is naturally very difficult to continuously maintain a lower body surface temperature.

However, once the other party has better and more accurate thermal imaging, and the police do not use any disguise, it is certain that they will not be found.

Even with such preparations, the enemy still couldn't get past the border defense, but Ren Xu knew that the opponent must have a back-up plan, and he couldn't give up just because he couldn't find it now.

He couldn't move at all, so Ren Xu also hid himself in a tree, using a large number of branches to shield himself from the heat.

He could vaguely remember what Master Qiao said, not to breathe out loudly, but to cover your lower lip and exhale the hot air to one side of your body.

Although these people may not have passed here, as long as they have, they will definitely find something!

At this moment, Ren Xu recalled many stories in his mind.

He has been in southern Xinjiang for the past two days, living with the local police and hearing about many heroic deeds of his predecessors.

There are really many things on the border that ordinary people cannot imagine.

Almost every year, someone dies on this line.

Many people cannot understand this simple sentence.

Some people will ask: "Is it true or false? Is this still the case now? This is 2016!"

In everyone's subconscious mind, with the country developing so well and the people's living standards improving so much, coupled with various severe crackdowns, there will be fewer and fewer cases like this, right?

This is not the case.

More and more people like money very, very much. What they say every day is "Nothing else is useful, I just make money." Among them, 1% of people go astray, and 100% of people go astray. Once they turn to the road of crime, there must be a lot of people who are on the road of crime.

Moreover, this kind of thing in recent years is not only the benefit of the thing itself, but also the continuous support of the beautiful country and others behind the scenes.

The moonlight was not very bright, and Ren Xu's sight was not very good. Just because he was at a high place did not mean his sight was very good, because there were too many trees.

All he could rely on was the thermal imager, which was his eye, a very wide eye.

I heard that the year before last, there was an old policeman nearby here who was beaten to death for trying to block cross-border smugglers. But apart from that, the police also used weapons to kill four or five gangsters.

Thinking of these, Ren Xu's mood became calmer and calmer.

A spot suddenly lit up on the thermal imager. There was a small heat source in the distance. It looked very small, but it appeared in an instant, and then the temperature index became lower and lower, and then disappeared.

Ren Xu frowned, he didn't know what was going on, but he knew what to do.

The famous war correspondent Robert Capa said, “If you don’t take a good picture, it’s because you’re not close enough.”

This sentence is the honor of all war reporters. Ren Xu roughly judged the distance just now, it was estimated to be 300 meters. He climbed down from the back of the tree, and then walked softly towards the place where the light had just been lit. On the way , constantly letting trees block the heat source of his body and reducing the exposed surface of his body as much as possible.

After walking almost 200 meters, Ren Xu hid himself again and took out the thermal imager. He suddenly saw several human figures!

At this moment, Ren Xu's body hormones were secreted rapidly, but at the same time he was desperately trying to reduce the area of ​​​​his body exposed to the outside world. The opponent really had a master!

Two to three hundred meters away, the thermal imaging cameras of Ren Xu and others could not see each other at all!

At this time, Ren Xu already knew what the red dot was about.

Someone in the opponent's team farted!

!!!

They were close enough. Ren Xu was not greedy for success. His position at the moment was already very dangerous. He would definitely be discovered if he went further. Since he could confirm from the thermal imaging that there were many people on the other side, he didn't run away!

No matter how cunning a rabbit is, there is no way to do things like this.

Ren Xu immediately retreated behind a big tree, then informed his cousin of the situation, and at the same time, his location.

At this moment, almost all the forces nearby gathered around.

It's an exaggeration to say that it would take at least an hour or two to form a truly valuable encirclement with a radius of ten kilometers and mountainous terrain.

It wouldn't make much sense for a helicopter to fly over. The other party dispersed and escaped, and it was still unclear who the main culprit was.

Ren Xu followed slowly. He had a strong intuition that he couldn't get any closer. No matter how close the trees were, they couldn't cover him at all!

Fortunately, he is alone and there are more than a dozen people on the other side, otherwise the trouble will be big!

Because he was worried that the other party could detect his signal, he turned off all the radios on his body after sending the positioning once.

Ren Xu knew that the other party must be going straight to the border. There were not many border guards here, but he didn't need to worry about that. He knew that Ren Hao would definitely notify the other side.

However, at this moment, Ren Xu's thermal imager became dim again, and he could no longer see the other party.

In other words, the surface temperature of the other party that had just risen slightly dropped again through unknown means.

Unable to follow any longer, Ren Xu felt a strong danger, and he began to retreat slowly while hiding.

Even after retreating for hundreds of meters, he still didn't lose the sense of danger.

The opponent's thermal imaging instrument is at least five hundred meters away. If he doesn't know the opponent's position now, he doesn't know where the "behind the tree" is. Once the opponent adjusts his direction, his position will be exposed immediately. Not only will he If it's over, the other party will be extremely alert and quickly change paths.

However, just when Ren Xu was slowly retreating desperately, he suddenly felt that the soles of his feet were empty, and he immediately fell beside the tree, not knowing where he fell.
