Many things, what is missing is just a clue, and when there is a breakthrough point, everything will fall into place. Pen ~ fun ~ pavilion www.biquge.info

The bomb shelter naturally had its own air supply equipment, and according to the words of the young man before his death, it was evident that there were many people living in their quarters, and the temperature produced was obviously much higher than the general cold of late autumn and early winter.

The blast robot quickly changed the search method, from the original near-ground search to the air over the entire mountain, under the all-round view of the night vision camera, the temperature mapping on the mountain soon appeared on the portable tablet of individual soldiers.

"There are 17 moving red patches, which are supposed to be rats based on their size, but there are fixed reddish areas...... It's a little too big, doesn't it look like a hidden vent? Alex looked at the reddish areas on the screen that connected and covered almost the entire mountain, and he was a little uncertain, but there was really no other redder area, and he turned his puzzled gaze to Andre.

"The commander has updated the order, looking for the cryogenic patch." A very simple reason, how can the military's air-raid shelter not consider the impact of temperature difference on exposure at the beginning of the design, the air outlet of the air-raid shelter must be disguised, and the most basic method is to cool the hot air generated by human activities in the air-raid shelter and then discharge, so that the air outlet and the mountain are perfectly integrated, so as to achieve the effect of deceiving the thermal induction equipment.

Combined with the study of the design of the air outlet of the Guangling underground base, Qin Feng concluded that the cooling temperature must be controlled by the computer, and the temperature is raised or cooled down according to the temperature on the surface of the mountain at all times.

And what came out of the cave mountain were three bad young men with tattoos, which basically ruled out the possibility that there were troops stationed in the air-raid shelter, and a group of civilians could run military equipment without leaking, Qin Feng really didn't believe it.

"There are two areas that show cold and cold color patches, and the size is consistent with the characteristics of the vents." Alex quickly found two small dots caught in the gaps in the large reddish area, and the two light blue ones were particularly glaring under special attention.

"It's an abandoned bomb shelter, I don't know how they found it." Qin Feng's eyes showed a hint of curiosity.

Since the vent shows a low temperature, it proves that the emitted gas has been filtered, but the temperature obviously does not match the current temperature of the mountain, which means that the temperature of the filter is not controlled by the people who live in the mountain today, but should be left behind by the last wave of evacuated soldiers.

Although no matter how you think about it, I feel that there are still some loopholes in my inference, but in terms of the facts that have been proved so far, his inference is still correct. At this moment, Qin Feng was like Obama who was staying in the White House watching the Navy SEALs kill bin Laden on the screen, and he was in his command car near the front line, paying full attention to the every move of the 025 team.

The size of the air-raid shelter cannot be deduced from the symmetrical vents on both sides of the mountain, after all, no one knows how deep the connection between the vents and the air-raid shelter is, and it is possible that the entire belly of the mountain has been hollowed out, or the air-raid shelter is located very deep underground.

Except for the dark mines found under the road signs, the team that carefully went to the vents did not find any explosives on the surface of the mountain, but there were quite a few primitive and crude traps, but they did not look like they were used to trap bugs, but more like they were used to trap people who fled in panic.

The thrilling process of avoiding the traps along the way also made the soldiers realize that there must be an important place behind the road sign, and there may be three motorcycles exiting not far away. But no one suggested going back and investigating.

Just kidding, they're infiltrating the squad, who has ever seen the Bright and Honest infiltrate through the gate?

In order to increase the success rate of the operation, the team is divided into two teams of six people each, and the only remaining blasting robot will act as a striker, responsible for detecting the route into the pipeline.

Getting in through the vents was the safest way the soldiers could think of.

Bomb shelters are built like tunnels, with a large entrance that everyone can see, so that nearby residents can take refuge, and those bomb shelters do not require special ventilation equipment. However, if it is a completely military bomb shelter, the exit is set up extremely secret, and its vents are naturally built in places that ordinary people can hardly think of, or simply cannot easily reach.

These two vents are built deep in the dense forest on the slope of the mountain, and the trees growing almost next to each other hide the vents.

Several soldiers slashed through the trees with their hot knives in hand, and a group of dark shadows surrounded them, watching vigilantly.

"I hope no one notices the light here." André glanced back, and in the dark of the night, the wielded thermoelectric knife looked as striking as a laser sword from Star Wars.

If it weren't for the urgency of time, he wouldn't agree to heat the blade to the point of glowing.

"Sir! Found the vent! ”

There was a very low voice in the headset, and Andrei's spirit suddenly shook.

"Burst bots ahead, everyone in!"

After all, it is the ventilation duct of the air-raid shelter, and it will not compare to the intricacies of the military base, if strictly speaking, this is a chimney that can barely accommodate one person curled up to pass, and the cold air flow after cooling is sprayed from the bottom of the moor, and the soldiers who finally chose to sneak in had to hold their breath as much as possible, without him, the air was too cold, and if the mask was worn, the hot air would fog up the lens of the night vision device.

Since Qin Feng founded the army, the most carried out in the assault operation is the rope landing, for this the army has a wealth of experience, the process of infiltrating the bomb shelter is almost completely in accordance with the textbook accuracy, after the blast robot cut a line, shut down the most threatening constantly rotating turbofan, the two groups of soldiers are only one column away from the bomb shelter, through the fine grid bar, you can clearly see the scene in the bomb shelter.

Just this look made Andrei's brow furrow.

"Woohoo......" A young girl struggled desperately, her face covered by black hair pouring down her head, and her mouth could be seen blocked by a black rag-like object through the gap where she frantically shook her head.

"Smack!"

This was not the expected slap, but a hard punch!

Who would have thought that this punch would actually fall on a girl's face, and across the screen, Qin Feng's pupils almost shrank like pinpoints.

He turned out... I saw that the "rag" that was forced out of the girl's mouth turned out to be an inner ......

With a "whoosh", the two intelligence officers in the command cabin, who were concentrating on processing the information at hand, looked at the commander who suddenly stood up from his seat in a daze, and looked at his facial features that were almost twisted together...... What happened?

Noticing the concerned gazes sent by the two women, Qin Feng pursed his lips and sat down firmly, he had already given an order without scruples, believing that the 025 team would "ruthlessly" deal with these scum.

The boxing girl was a sturdy man with a naked upper body, and the narrow scars were all over his chest and back, which could be seen to be the marks left by the claws of the insects, who would have thought that such a person who could be treated as a good man in the settlement would treat a helpless girl like this.

"! So can't help but fight! The sturdy man didn't look at the few teeth that flew out, grabbed the girl's short hair, and lifted it up with all his might.

"Dare to lure bugs over? What the thought we'd believe you? If you get it, you'll have it! ”

The more the man spoke, the more angry he became, and he slapped the girl again with his backhand.

"Brother Huang, you dissipate your anger, and if you continue to fight, you won't be able to speak."

A thin man in body armor standing next to the sturdy man snorted for a long time, and finally popped up such a sentence.

"Lao Tzu teaches people to take care of it!" Brother Huang glanced back in disgust, "What else do you need to ask?" My brothers were killed by this! Ask a fart! ”

The thin man's Adam's apple moved unnaturally, and he shrunk his neck, as if he wanted to shrink his whole body into body armor.

Brother Huang, who had red eyes, glared at the man fiercely, and after forcing the latter to dare not raise his head at all, he turned his head sharply and stared at the girl who was tied to a wooden chair with duct tape.

The other party's originally dim expression suddenly became extremely frightened, and the tearing pain from his head and body could not compare to the fear in his heart at this moment, and the Huang brother in front of him was like a cobra dripping with venom, staring at his prey coldly.
