The competition of endurance unfolded on both sides of this canyon, and the gap formed between Yun Dong and the other three people and the pursuit team gradually narrowed in this consumption, even so, Yun Dong still couldn't find the sixth sniper point that he believed must exist.

Eva even had doubts about Yun Dong's conclusion, and when she saw Yun Dong's solemn appearance, she did not dare to raise objections, but stood on the sidelines while observing the pursuing enemy behind,

This stop was more than five hours, and the afterglow on the horizon was already half red in the sky, and the clouds had not yet risen from the observation post.

Gradually, the noise of chasing soldiers and the barking of dogs could be heard at the foot of the mountain behind him, but Yun Dong was still indifferent, quietly holding the telescope, as if it had become a sculpture, standing still.

The Red Devil had also gotten up, he took this opportunity to sleep well, among the three people, he was the most energetic, and when he woke up, he saw that Yun Dong was still in place, he couldn't help but be startled, walked to his sister's side and asked, "What's wrong,"

Eva told him the results of Yun Dong's judgment and observation, he thought for a moment, slowly approached Yun Dong and said, "Otherwise, I'll touch it first, find the hidden snipers on the hillside on our side, kill them, and see how the other party reacts,"

Yun Dong's face sank and said: "No, this will not only expose our location, but you will also be very dangerous, the other five points will firmly trap you on this side of the hillside, and in the end you will be a dead end,"

"Then what should I do, I can't stop here, the people behind me will have to catch up," the Red Devil said anxiously,

Yun Dong didn't seem to hear his words, raised his head to look at the sunset on the horizon, and muttered, "It's getting dark,"

The Red Devil looked at Yun Dong as if he didn't understand, and said in his heart: Could it be that you can find the sixth sniper position when it's dark?

Yun Dong finally left the observation post where he had been lying for nearly five hours, and the three of them reunited, Yun Dong said to the Nikolai brothers and sisters: "We are now going up the mountain, above the snow line, we may have to spend the night there tonight, wear a cold disguise, the temperature there is a little unbearable,"

The Red Devil asked puzzled, "Why do you want to spend the night there, is there a problem here?"

Yun Dong nodded: "Yes, if we stay here overnight, we will be discovered by them, because they have thermal imaging night vision devices, the surface of objects above zero degrees will emit infrared rays, according to the difference in temperature, the images they form are also different, thermal imaging technology is also formed according to this principle, the difference between the temperature of the human body and the temperature of other objects, let the detector measure the infrared difference between the target itself and the background and can get different infrared images, the image formed by thermal infrared is called a heat map, So we went above the snow line, where the temperature kept us from being detected by the other party, and Shang Yi came to prepare a device for me this time, which is the latest product, and the range can reach more than 1500 meters, so relying on it, we are very likely to find all the targets,"

The Red Devil said with envy: "I know this thing, but the general thermal imaging night vision device can also see the distance within 200 meters to 400 meters, and the price is very expensive, now the night vision device that can measure the distance within 1000 meters is close to 100,000 m gold, let alone you,"

Yun Dong smiled shallowly: "Modern warfare is high-tech,"

The three of them began to move above the snow line at the top of the mountain, and the temperature became lower and lower, and when they approached the snow line, they changed into pure white camouflage suits, crawled on the ground, crawled at a very slow speed, and finally hid behind several large rocks, the Red Devil stayed alone behind one rock, Eva did not want to be separated from Yundong, and the two snuggled up behind another rock,

The sunset on the horizon exhausted the last trace of energy, and the entire mountain field fell into darkness, but the competition continued to unfold in this cold darkness.

Yun Dong grabbed a handful of snow and gently wiped his face, the cold snow water stimulated the brain nerves, which made him feel vibrate, and then he slowly took out a camera-like device from his backpack, turned on the switch, lifted it, and looked at the opposite two mountains and canyons, after debugging for a while, the image of the mountain began to appear on the electronic screen behind it,

The mountain they were on was about a thousand meters away from the opposite mountain, but Yun Dong's current location was about two thousand meters away from the bottom of the canyon, and he couldn't see the bottom of the canyon clearly, but the target he wanted to observe was not below, but on the opposite mountain.

All sorts of red bright spots began to appear on the screen, and depending on the shape of the body, they could tell which ones were animals and which were human beings.

Slowly moving the instrument, according to the position he judged with the naked eye during the day, he excluded those areas that were limited by distance, controlled the search range to the position halfway up the mountain, and successfully found two points, a total of four human images, all of which were sniper teams equipped with observers,

The other three Yundong already knew they were there, and the one he wanted to find now was the sixth, but he scanned the instrument for a week, and still didn't see the target he was trying to find.

At this time, Yun Dong couldn't help but doubt himself: could it be that his judgment was wrong, and there was no sixth sniper point at all,

His eyes revealed a trace of confusion, and he couldn't help but carefully look at this canyon and the surrounding terrain again, this canyon divides the peak where it is located into two with the two connected peaks opposite, there is a gap where the two peaks are connected opposite, the gap is not big, a very thin stream of water flows down from the gap, like a white water curtain, if it rains, it is even a small waterfall, the clouds on both sides of the gap have been observed with telescopes, it is very smooth, there is no rock block, there is no place to hide people, And after viewing with a thermal imaging night vision device, there seems to be only a thin red line on the image, which should not be the shape of the human body, if a sniper position is set up there, the sniper must be immersed in water, which seems unlikely, as for other positions, neither the telescope nor the thermal imaging have found any abnormality,

Yun Donghu suspiciously raised the instrument in his hand in front of Eva, aimed at the gap, pointed to the red line on the image and asked softly, "Eva, do you see this like a human shape?"

At first glance, Eva shook her head affirmatively and said: "No, it should be that the water temperature there is higher, emitting infrared rays, and then forming a red line on the image, and if it is really a person, how can he endure it after being immersed in the water for so long,"

Yun Dong listened to Eva's words, looked at the instrument in his hand suspiciously, nodded and said, "It makes sense, but..."
