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

The opponent has a master...

Having a master means that the other party must have the ability to avoid thermal imaging or...

Or the other party also has a thermal imager! Even higher accuracy!

The imaging of a thermal imager is basically a temperature difference. At present, the outside temperature at night tends to be 16 degrees Celsius, which is 20 degrees different from the human body. Under the action of the thermal imager, it is a beacon.

Some people will lower the 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 body surface temperature.

Therefore, the current better way to protect the thermal imager is to cover or wear some special clothes that block a certain amount of heat radiation, such as firefighter's clothes.

But this still doesn't work. If this kind of clothing is walking through the mountains and forests, the thermal imager may not be able to see it, but it is silvery...

Someone has said, can't you put on a layer of shiny silver firefighting suit first, and then put on something else?

No...

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

Masking is effective. In addition, it is constantly maintaining a low body surface temperature, which is naturally very difficult.

However, once the opponent has better and more precise thermal imaging, and the police do not do anything to disguise, it is certain that they will not be found.

With such preparations, the enemy still can't make it to the border defense, but Ren Xu knows that the opponent must still have a back hand, and he cannot give up just because he can't find it now.

He couldn't move at all, Ren Xu also hid himself in a tree, using a large number of branches to cover his own heat.

He can vaguely remember what Master Qiao said, don't breathe outside, but wrap your lower lip and spit out hot air to your side.

...

Although these people may not have lived here, as long as they do, he must discover!

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

He came to southern Xinjiang in the past two days to live with the local police and heard about the heroic deeds of his predecessors.

At the border, there are really many things that ordinary people can't imagine.

Almost every year, there are sacrifices on this line.

Many people can't understand this simple sentence.

Some people will ask: "Really? Is this still the case? It's 2016!"

In your subconscious mind, the country has developed so well, the people's living standards have improved so much, and all kinds of severe crackdowns are added. Will such cases become fewer and fewer, right?

This is not the case.

More and more people like money very, very much. Everyday they say "Nothing else is useful, I just make money." One percent of the people here go wrong, and one percent of those who go wrong. As soon as they walk on the path of crime, one percent of the people who commit crimes are traffickers...In short, there must be a lot of them.

Moreover, these kinds of things in these years are not just the interests of the thing itself, but also the continuous support of beautiful countries and so on behind the scenes.

The moonlight is not bright, and Ren Xu's line of sight is not very good. A high place does not mean that there is a good line of sight, because there are too many trees.

All he can rely on is the thermal imager, which is his eyes, the eyes with a wide range.

I heard that there was an old policeman near here the year before last, who was beaten to death in order to block cross-border smugglers. But in addition to this, the police also used weapons to kill four or five criminals.

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

...

A spot suddenly lit up on the thermal imager, and 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 once said, "If you are not shooting well enough, it is because you are not close enough."

This sentence is the glory of all war reporters. Ren Xu roughly judged the distance just now. It is estimated to be 300 meters. He climbed down from the back of the tree, and then walked quietly towards the place that had just been lighted. , Constantly let the trees cover the heat source of his body, and reduce the exposed surface of his body as much as possible.

After walking for 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 desperately reduced the area of ​​his body exposed to the outside, the other party really has a master!

Two or three hundred meters away, Ren Xu and others' thermal imaging cameras couldn't see each other at all!

At this time, Ren Xu already knew what was going on with the red dot just now.

Someone in the opponent's team put a fart!

The distance is close enough, Ren Xu is not greedy for power, his position at the moment is already very dangerous, and he will definitely be found further forward. Since it can be determined from the thermal imaging that there are a lot of people on the other side, then he did not run!

No matter how cunning rabbit Sanku, there is no such thing.

Ren Xu immediately retreated behind a big tree, and then sent his cousin the situation, and at the same time, he posted his own position.

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

Speaking of an exaggeration, it takes at least one or two hours to form a truly valuable encirclement with a radius of ten kilometers and mountains.

It doesn't make much sense for the helicopter to fly over, and the opponent scattered and escaped, still not sure where the main culprit was.

Ren Xu slowly followed. He had a strong instinct that he couldn't get closer, and he couldn't cover him when he entered the trees!

Fortunately, he is one person, with a dozen or so people on the other side, otherwise the trouble will be big!

Because he was worried that the other party would be able to detect his signal, he turned off after sending a positioning, and all the radios on his body were turned off.

Ren Xu knew that the other party must have gone straight to the border~lightnovelpub.net~ There were not many border guards, but he didn't need to worry about this, he knew that Ren Hao would definitely inform there.

However, at this moment, Ren Xu's thermal imaging camera became dim again, and he couldn't see the other party again.

In other words, the other party's surface temperature that had just increased a bit, but did not know how to lower it.

No longer able to follow, Ren Xu felt a strong danger, and he began to slowly retreat under covert conditions.

It was estimated to be hundreds of meters away, and he did not lose that sense of danger.

The opponent’s thermal imaging equipment is at least 500 meters away. He doesn’t know the opponent’s location now, and he doesn’t know where it belongs to the "behind the tree." When it's over, the other party will be very alert and change lanes quickly.

However, when Ren Xu desperately retreated slowly, he suddenly felt the soles of his feet hollow, and he immediately fell by the tree, not knowing where he fell.
