Xue Lang and they were no more than sixty kilometers away from the core base, and in the middle, there was no zài secret outpost, or rather, the dark outpost had been evacuated.

As long as they are close to the base, the detection range of the life detection radar is not the kind of civilian search and rescue, they can be about a kilometer, underground, and can exceed 50 meters.

After all, this is not to mention the rock geology, but also a karst cave, and the clutter generated by the hole will affect the detection.

So, they don't need too many sentry posts to stay outside to be the enemy's tongue.

When Xue Lang and the others were running wildly, all the small outposts on the periphery had been withdrawn, and in the huge forest, there was nothing but insects and birds.

Xue Lang didn't dare to be careless, but he wasn't very worried.

Because, they are not here to fight, or they will not take jasmine with them.

To put it mildly, it is to steal the crystals that may be stored in zài, so you can escape at any time, without having to fight hard, let alone worry.

Their speed was only sixty kilometers and two hours, and at the moment when the sky was slightly bright and the fish belly was white in the east, they were only about five kilometers away from the base.

But Xue Lang didn't come any closer, and the team stopped in a hollow position and disappeared into the grass.

Everyone has the phenomenon of panting and sweating.

Except for Jasmine, she doesn't touch the ground at all, where does the sweat come from?

The mountain bag in front of Xue Lang said: "Sir, after the mountain bag, you should enter the opponent's radar range if you go a few hundred meters ahead, according to the opponent's technology that you have mastered before, the straight line is in an open environment, the detection distance should be about two thousand five to three thousand meters, and the underground is about fifty meters, is it at this position that you start looking for the entrance to the underground?" ”

Liu Yucheng nodded, took out his compass, squatted in the grass and said: "This is a karst landform of the whole landform, the underground is full of holes, and the water vapor is abundant, it is not difficult to find a passable passage, first lock the largest underground river." ”

"Okay."

Xue Lang took off his backpack and said: "Everyone rest, eat and replenish the body, and when we encounter a water source, we will replenish the drinking water, and we estimate that we will stay underground for a few days." ”

Be!

Everyone whispered their orders.

Here, their perception is not so close that they don't know it, not to mention, there is also a super radar, Xue Lang is here.

Everyone ate silently, and Jasmine also followed to replenish food, although not hungry.

They hadn't eaten a few bites, and Liu Yucheng took the compass and didn't move in one direction, and then whispered: "In this direction, the distance of about a kilometer is the underground river, where the water vapor is the most vigorous, according to the direction, it is also in line with the flow direction of the underground river in the base." ”

Kilometer...... In the direction of Xue Lang, it is confirmed that even if it passes, it will not overlap with the detection distance of the base, because it is not in the direction of the base, it is oblique, and it is estimated that even if it is close, it will be four thousand meters away from the base.

Knowing the direction, everyone rested, explored, and was not in a hurry.

While they were resting, the head of the base here, Abner, frowned.

Two hours passed, and there was no trace of the enemy from the periphery.

And in the second lap, there has been no movement except for the second position being disturbed.

Is the enemy just a temptation?

He wasn't sure.

This place was breached by the enemy before, and it was slaughtered, even the scientific researchers were not spared, and the children of those reserve forces did not escape the poison, so he had to be extra careful.

However, the enemy has not moved so far, so he is confused, what is the enemy going to do?

Was it just a false alarm?

Although he didn't understand why, he was definitely not careless, so he didn't dismiss the alarm because he didn't find any trace of the enemy.

At this time, the defensive ring of the outer base is no longer just equipment, but there are several groups of personnel lurking in the grass in the middle of each monitoring point.

Now, not to mention the iron wall, at least there will be no one who crosses the defense and does not know, even if hundreds of people are invested in it.

Xue Lang and the others rested for a while, and when they were even, they quietly touched the direction pointed by Liu Yucheng.

Here, the underground base is a huge karst cave reconstructed, and this is still a karst landform of the whole landscape, and no one doubts that here, the underground is connected.

At this time, they no longer run rapidly, but move as gently as a tanuki prey, silently touching the established direction.

Xue Lang's perception has always been open, mainly focusing on the underground.

His ability is even more awesome than holographic scanning.

A structure that can accurately know the position of the naked eye.

As he went, he suddenly pointed in a direction, and everyone was silently following, turning to a more outerly position.

After walking less than fifty meters, Xue Lang slowly squatted down, and explored the bare rocks in the square grass.

He must control his actions in an absolutely safe and undetected manner, even if there are biological detectors, infrared alarms and the like, he must find out in advance and destroy them.

Sure enough, there he found several infrared alarms, which belonged to independent devices, not in any network, and were independent devices that relied on unlimited signals to transmit alarms.

Xue Lang didn't let Bingling Hua invade, they didn't enter the base, so there was no need to bother.

Finding the alarm doesn't have to be that much trouble.

These devices are not in the network, which means that they are not in the defense system in the first place.

Xue Lang signaled, Bing Linghua quickly turned on the interference, and then, at the moment when everyone was from the position of those alarms on the terminal, with Xue Lang's gesture, the figure flashed, Zuo Boyang, Liu Luocheng, including Jasmine, all jumped up, running in the grass like a cheetah, swimming like a giant python blades of grass, and swooping down on their assigned alarms like lightning.

When they got closer, whether it was disguised as a stone, dead wood, or a tree, all of them were useless in a matter of seconds, but if the signal was detected, it still existed.

As Xue Lang jumped down from the tree, Bing Linghua quickly turned off the interference, and the status of all the alarms on the thin screen gave an OK gesture.

Xue Lang nodded, quietly touched it, and expelled the thunder along the way, coming to a location where there were no trees.

Everyone stepped on his footprints and came closer, not quite understanding what he was doing here.

But there are alarms, there are thunders, and there must be cats.

Xue Lang shook his head quietly for a second and said: "This was originally a big karst cave entrance, but unfortunately it collapsed, and the amount of excavation was too large. ”

Jasmine, who had not spoken since the beginning of the operation, smiled and said: "In this way, it shows that the speculation is correct, and the karst cave here is connected, otherwise the other party will not blow up here, and also left a thunderbolt and an alarm." ”

Liu Yucheng also nodded and said: "That's right, and the thunder is very new, it is definitely not something forgotten, and the electromagnetic of the siren is not old, and the power is sufficient." ”

Xue Lang raised his head, thought about it, and said: "Not to mention the explosion here, there are also defensive warning methods, which is enough to show that the underground caves are connected, at least some of them can be connected to the base a few kilometers away, and I want to find an entrance that can go down from the outside." ”

This is certainly the best solution, but only he can implement it.

I don't know how many years it has been blown up, and although there are no trees, if you want to go in, you just dig, and you don't have the tools to do anything for three days or five days.

So, they didn't stay long, exchanged briefly, and quietly left here.

When they searched for an entrance to the underground and wanted to dive into the underground near the location of the underground river, Abner was suspicious of the base.

Although he was a little agitated, he did not lose his ability to think.

He's not stupid in the first place, and as his name suggests, he's really full of wisdom.

There is no trace of the enemy now, more than a dozen UAVs have been lifted into the air, all of which are military UAVs with large ranges, military drones with missiles, and the altitude of the rise is more than a few hundred meters, on the ground, at all, unless there is a radar.

However, more than two hours had passed, and three hours had passed, and they had not even noticed a single figure.

But he still did not send his ultimate power, nor did he make the move to find the enemy, because his calculation was to destroy the enemy in the future.

But after more than three hours of no clues, he began to doubt his previous judgment.

These two disturbances were definitely not temptations, let alone false alarms caused by accidents.

In the command headquarters, everyone was silent.

They are eager for a great war, and they already have more than one hundred and two hundred super powers in their hands, although most of them are not fully enclosed armor, but they have helmets, breastplates, and elbow and knee joint protection.

These people are also beyond the scope of the elite soldier king, and I believe that if they face the enemy again, it will definitely not be the situation where the ultimate power has little effect because of the lack of skilled armor before, and they are being beaten by others.

But if you can't find an enemy, everything will be in vain.

Abner struggled to puff up his expensive cigar, a pure Cuban cigar, and his eyes fell silently in thought through the rising smoke.

Suddenly, his eyes widened suddenly, and he asked, "Have any of you ever heard that interference is in a straight line?" ”

In the quiet command room, everyone was startled by the sudden sound, and their eyes were on the boss.

Then, almost everyone's eyes lit up.

Abner was direct, but to the point.

Interference is a signal, a radial signal, even in the air and underground.

Then, it is impossible to save a straight line, only interfering with a certain width, but a few tens of kilometers longitudinally.

It's not a cannonball, it's just a fan-spreading thing, even if it's only aimed at the front.

However, there were only two groups that were disturbed.

In other words, the interference range of about 500 meters extends 20 kilometers away.

Everyone's eyes lit up, and they were shocked.

Doesn't this mean that the enemy is near?

At the very least, it has broken through the second line of defense, close to the core base.

How could they be so fast...... Everyone's eyes lit up.

The first time it is disturbed, it is usually thirty seconds.

The second time it was the same, it stopped in about 30 seconds.

The radiation distance of their equipment was 400 meters away from the front and back, and less than 500 meters, but no trace of the enemy was found.

Doesn't this mean that the enemy has already crossed the defensive position in thirty seconds?
