While Xue Lang and the others were studying how to get close and how to infiltrate here, the CIA base was also discussing countermeasures.

The satellite turned around, and they photographed the number of wolves, although it was not accurate, it was roughly three or four hundred.

The locations of those accidents have also been completely restored, and the wolves are actually fighting with them.

Running in circles around the prey, stepping on a bloody circle, stepping on all the weeds and vegetation, according to their knowledge of animals, what they know about wolves, this is a ritual that is difficult for people to understand.

In the photo, not a single corpse was torn to pieces, and the scene was covered with bloodstains, blades of grass, and branches were covered with blood and minced meat, which completely violated the principle of wolves.

In addition to feeding their stomachs and predating, wolves have always followed the principle of protecting the surrounding ecological environment, and will never participate in meaningless slaughter, nor do they do it. To tear up corpses without hiding them and not eating them, as it is now, is a sign of madness, a sign of destruction.

The main person in charge of the base, the supreme leader of the CIA here, Avanovich, had a solemn face, and he didn't know why these wolves were still worried about this primeval forest 400 kilometers in diameter all these years.

In a big war once in a few years, they can't get close to here for fifty kilometers, and at most they will attack a small team, and they will have to pay a heavy price, even if they eat the team, they will no longer be able to attack and stay away from this area.

And this year, more than 200 people were slaughtered, and they were all special forces-level fighters, which is unscientific.

Avanovich retracted his gaze from the tragic photos and said: "It seems that we are going to do a thorough clean-up and kill all the wolves here!" ”

"I agree."

A beautiful general agreed: "If you don't destroy them, this kind of war will continue, there is no guarantee for the safety of the team, it's not them, the team doesn't need a team of thirty people at all, five people are enough, and it can protect this place more closely, since they are close and don't attack, I suggest, just take the initiative to attack, go around from the spare exit, completely surround this area, and have a large-scale hunt!" ”

Aivanovich nodded and said: "Okay, the suggestion is adopted, everyone go down and prepare, start the action early tomorrow morning, let everyone rest well, and prepare to continue fighting." ”

"Yes!"

Everyone obeyed, and then, the soldiers who had been waiting for a day outside the base returned one after another, leaving only a little more normal defensive force, and abandoning the defense outside the first line of defense.

When they were ready for a hunt, Xue Lang analyzed the situation while chewing on the jerky.

He knows that the infrared detection here is all docking, that is, one side of the transmission, the other side of the reception, the equipment is relatively old, maybe there has been no accident for decades, maybe there is enough force here, there should be a small radar, detection within three kilometers, at least the kind of equipment of the position radar.

Coupled with the motion probes everywhere, even if the equipment is a little backward and so dense, not everyone can get close.

Landmines, too, are everywhere and are extremely densely laid. Everywhere except for the patrolled paths.

Everyone was silently chewing on the jerky, and it was too difficult to sneak in.

Here, it is far stricter than the Black Rose and Iron Scorpion mercenary groups, not with high means, but with a more clumsy method, but very effective. That is, manpower defense, backward equipment is intensive, there is no large-scale jamming equipment, these infrared, dynamic probes can not be controlled at all.

The Flying Eagle used an infrared emitter, the kind of battery, to point to the infrared detection and reception along the way, so that they were able to slowly approach the sinkhole along the path and discover the hidden place.

The motion probe there has been destroyed.

Zhang Bin is much more powerful than Feiying in this regard.

But the infrared light along the way was not destroyed, which is why it took a long time.

Thinking about it, Xue Lang raised his head and asked, "Moon Fox, you said you heard the roar of the machine?" ”

Liu Yucheng nodded and said: "Yes, the equipment is limited, and the last one to approach is the flying eagle, but I heard the sound of the fan turning and the hum of the motor." ”

The vents are there!

Xue Lang's eyes were blank, and then he said: "The others are on standby, drill the gopher and go with me." ”

Dressed lightly and disappeared into the darkness.

He and Zhang Bin followed the route that Zhang Bin and they walked, and soon arrived at the heavily defended area, and found that this was a ravine that was washed out of the mountain by soil erosion in the early years, overgrown with weeds, although it was not deep, only about half a meter, but it was definitely enough for people to dive into.

Along the ravine, the two of them swam quickly, and soon, Xue Lang's goggles saw the staggered red lines.

Xue Lang followed Zhang Bin and walked in the ditch, moving quickly. As he progressed, he saw that all the mines along the way had been cleared, thinking that it was the work of the Flying Eagle.

The two of them moved very carefully, following the path they had taken before, quietly navigating the darkness, occasionally destroying a motion probe.

After traveling more than 1,000 meters, he arrived at the area full of red lines, and then, Xue Lang saw the path.

The movement of the two of them became slower, and they cautiously crawled forward in the small trench that was not deep, heading towards the top of the mountain.

Finally, at the moment when the natural traces of the ditch could no longer hide their figures, they reached the top of this mountain bag.

Looking at the dense red lines in front of him, Xue Lang patted Zhang Bin's feet, and the two of them clinged closely, staggered by, and Xue Lang came to the front of the red line.

He took a closer look and made sure that the equipment wasn't old, but it wasn't the most advanced it is today. However, the inside is an infrared capture sensitive alarm.

That is, instead of emitting and receiving rays alone, it is similar to radar, which captures the infrared radiation source and triggers an alarm.

At this time, Zhang Bin pointed in a direction, and Xue Lang withdrew his gaze from observation and looked there.

There were actually bunkers, concrete structures, but they were crawling with vines, only the firing ports leaked out, and there were as many as five in a row, covering the entire gentle area of the top of the hill.

Fortunately, there was no one there, probably because of the relationship between the wolves, the shooting port could block people, but it couldn't stop the wolves from penetrating, I was afraid that wolves had sneaked in before, so I closed this place.

Subsequently, Xue Lang saw several similar targets in his sight, dozens of meters apart, hundreds of meters apart, and in the dimming telescope, he could barely see that there were fortifications.

All right......

Xue Lang was happy for a while.

If it weren't for those wolves, it is estimated that this place is really impermeable, and only special means can sneak in.

It's good now, the other party thinks that there are hundreds of wolves around, and it is impossible for people to get close, so they can rest assured and boldly evacuate the ground defense, but it is cheaper for themselves.

After observing, he put away his binoculars and studied the route ahead again.

In the darkness, he had already seen the cliff opposite, which was the edge of the sinkhole, more than fifty meters in diameter.

Confirming that the motion probes here were all destroyed, Xue Lang moved quietly, moved to the vicinity of the first infrared alarm that received the emitting, judged which one was transmitted, turned around and signaled Zhang Bin to go to the other side of the transmitter, wait for the signal, and destroy it.

Zhang Bin was ordered to hand Xue Lang a small electronic gadget, and then crawled over there.

Xue Lang carefully pointed the transmitter at the receiving window, activated the transmitter, and made a gesture in the dark.

Zhang Bin quickly disassembled without hesitation, and rushed the launch port to the ground behind, but did not destroy the equipment at work.

Xue Lang was also busy quickly, but instead of dropping the device, he quickly removed the receiving sensor and passed through the loop to keep it working, but he didn't need to receive infrared signals, and of course, he wouldn't alarm him.

This is to avoid the fact that once the mechanical damage to these devices is made, the base will come to view.

Even the motion-capturing cameras are the same, the work continues, it works, but it doesn't work anymore.

Without caring about the other device in the opposite direction, the two of them moved forward again, approached the second one, and quickly solved the alarm.

In half an hour, the two of them destroyed more than 40 infrared alarms and completely opened this road to pass.

After a short break, Xue Lang took out two small alloy bottles, one left and one right, and fixed them on both sides of the tactical vest, just under his armpit.

In the sound of smacking, a puff of smoke rose from Xue Lang's body, although it was not thick, but the obvious fog was still visible.

Zhang Bin didn't move, because the amount of liquid nitrogen in this special bottle was not much, and they only carried four bottles, just in case they needed to cut the steel or break the locks that could not be opened. One had already been used before, and they couldn't afford to waste it.

Such a slow eruption lasts for more than ten minutes at most, but it will not cause hypoxic asphyxia to nearby people because the concentration is too high.

Xue Lang raised his hands flat, avoiding the spurted gas from directly touching the skin, causing frostbite, breathing slowly, but his feet moved quickly, and he ran to the infrared capture instrument in a few vertical leaps, quickly disassembled, and in just a few tens of seconds, he got rid of this guy who was generally difficult to avoid, and then ran wildly again, and in just a few minutes, he reached the edge of the sinkhole.

Closing the bottle, I heard a buzzing sound and confirmed my judgment.

Vents, it seems to be right here!

He quietly moved forward, carefully probing and looking down.

On the opposite side, there is no trace of a similar vent, but as described by the flying eagle, the rock wall here is not only not vertical, but also sunken in, that is, from here to sag, it is impossible to get close to the rock wall below, roughly estimated, even in the middle of the position, I am afraid that it is at least five meters away, there is nothing to climb, very smooth.

It is precisely because of this that those infrared transmitter receivers cannot be destroyed, criss-crossed, there are no gaps at all, not to mention, there are dense motion probes. Before you get close to those devices, you'll be discovered.

As for the temperature probe, it has little effect, there is liquid nitrogen, not to mention the temperature sensing, even the infrared capture equipment is ineffective, it is even more finished.

Xue Lang retracted his gaze and began to look for ventilation equipment, wondering if he could put ylang-ylang into the suction port smoothly, as long as it went well, these instruments were all furnishings, no one, what about the alarm?

Judging by the sound, he moved slowly, turned on the nitrogen, destroyed an infrared capture alarm again, and then saw the target as he circled fifty meters away.

The vent rushes down, and there is more than one, but the position is close to the middle of the cliff, and it must be at least ten meters away from the cliff to rappel down.

Then, Xue Lang continued to sink down to the bottom, and saw that there were two more vents, five or six meters from the ground, six or seven meters from the ground.

Xue Lang saw the situation below, his brows furrowed, and then, his eyes lit up, his brows stretched, and in a flash, he arrived in front of Zhang Bin, and made several gestures in a row, ordering him to go back and call everyone, ready to sneak in.
