Lei Dong focused his eyes and all his energy on the opposite side of the 1,000-meter radius. Judging by the conventional situation, where the electronic signal is most dense, the entrance to the enemy's base will definitely be nearby.

From left to right, from top to bottom, Lei Dong searched inch by inch, trying to find the entrance to the base. Bei Shiliang manipulated all kinds of equipment to carry out exploration and monitoring in an intense and orderly manner.

From the edge of the jungle, there is an open field of about two kilometers, there are no tall trees, only low thatch and bushes, and it is obvious that in order to guard against foreign enemies, the little devil specially cleared the shooting boundary. At the end of the open field, there are rolling hills.

Searching along the mountains, Lei Dong soon discovered the anomaly. A cave-like base appeared in front of Lei Dong's eyes.

The design of this base is very hidden, and it is difficult for ordinary people to find it unless they have specifically studied this aspect and deliberately observed it. There are no outbuildings outside the site, and the natural landscape and vegetation are completely maintained. The entrance to the site is in a U-shape, flanked by completely uneven mountain walls, with no signs of man-made work except for a few excavation marks.

Outside the entrance, there is an overgrown path, there are faint rut marks on the passage, it is obvious that there are not many vehicles entering and exiting here, the rut marks are very shallow, if it is not for some grass lying on it, it is difficult to find.

A swarthy approach leads from the entrance to the inside. From the perspective of thunder, this approach road is invisible from tens of meters away. But Lei Dong can be sure that the guide has not disappeared, but turned a sharp bend at a right angle, leading to another direction, and there should be many such right-angle turns in the approach road, and after reinforcement design, and the end of the approach road is the real entrance to the base. This is also the design and construction commonly adopted by most cavern-type bases, and their purpose is to deal with missile strikes.

"Damn it, there's a set!" Although he hated it very much in his heart, Lei Dong still praised the little devil who built this cave-style base. He has even figured out the general process of the little devil's construction of this base: Under the pretext that it is necessary to seal the reactor and build a stainless steel water tank to deal with nuclear pollution, a large number of construction teams have been transferred in, and a military facility construction team has been mixed into these construction teams, and under the cover of the nuclear pollution disposal project, they have extremely secretly excavated a cave on the mountain, and the excavated soil and rock have been transported through the tunnel of the nuclear engineering construction unit, so that they can evade the surveillance of the reconnaissance satellites of hostile countries.

After the completion of the main project of the cavern, the required reserve materials and equipment will be mixed in the convoy of nuclear pollution treatment materials, and secretly transported into the cavern for storage, installation and commissioning. After all this preliminary work was completed, the necessary reserved tunnels were drilled in many directions in the cave - these tunnels were not completely connected to the outside world, but about 50 centimeters of mountain mass were reserved - and finally, the main tunnel connected to the civil tunnel was closed, leaving only a narrow passage for personnel to enter and exit.

After all these arches are completed, the construction team dealing with the nuclear contamination will definitely be "completed in time" and evacuated, and the base personnel will immediately enter and blast up the 50-centimeter-thick mountain through the tunnel in the reserved tunnel in the desired direction, and the base will be immediately started.

What a trick to hide from the world!

The little devil's ability to make troubles is really not small.

"! It's so perverted! was sighing and despising the little devil's thunder, and suddenly heard Bei Shiliang scolding softly.

"What's wrong?"

"Boss, look," Bei Shiliang pointed in front of him hatefully, his tone was a little depressed, "Front, at such a distance, the little devils have set up 53 infrared induction alarms, 27 of which have no wireless signals, and they must have used optical fibers to transmit alarm signals!" Also, the C-C-T-V system that transmits signals with 15 optical fibers! ”

Lei Dong gasped.

In such a palm-sized place, arranging such a complex alarm system is simply perverted, a great waste, and a crime!

In the face of such a dense all-round electronic monitoring and alarm system, even Lei Dong felt a little helpless for the first time.

Now things are obvious, the little devil is in such a strong radiation location, and he does not hesitate to build such a base, which is a mine array and a mysterious formation, and an all-round electronic alert, there must be something extremely important in it, and more than ninety percent of dozens of tons of weapon-grade plutonium may exist here. Even if it's not weapon-grade plutonium, it's certainly not something that benefits world peace, and as long as you bite it here, the little devil will definitely bleed from pain.

But now the question is, how do you get in?

A direct attack is not something to think about, and the primary principle of special operations is to strike a fierce blow by surprise with the support of powerful intelligence, that is, a sneak attack, and a frontal assault is not a last resort, and it has never been the choice of special forces. If there is any big movement, in case it is stuck by the enemy, wait for the large troops stationed around to come up, not to mention the powerful firepower, even if you rely on the crowd, you can pile the squad to death!

What's more, it is a big problem to get past the open area of two kilometers in front of you, and it is very likely that before you have taken a few steps, you will be discovered by the enemy's electronic surveillance, which will lead to a tragic result.

"!" Lei Dong scolded and asked Bei Shiliang, "Is it possible to block the electronic signal?" ”

Bei Shiliang groaned, observed the equipment in front of him for a while before nodding and said: "The radio signal can be done, the power of the jammer we carry is enough, and I can find the law of the other party's radio signal, so as to simulate their signal, and send a normal signal to their alarm system after the shielding, but ......"

"But the signal transmitted by fiber optics is not good, right?" Lei Dong asked.

Bei Shiliang didn't speak, just nodded.

Lei Dong exhaled a mouthful of turbid air depressedly, although he had expected this to be the result, but a large pot of popular braised pork was placed in front of him, but he couldn't eat it, this feeling really made Lei Dong depressed and unwilling.

Bei Shiliang suddenly said: "Otherwise, I will crawl over secretly, as long as I can touch the optical cable, I will be sure to control it, and I will be able to invade the computer network of the base......"

Bei Shiliang was almost moved by his plan, but Lei Dong shook his head: "No! Not to mention this large open area, there is basically no terrain cover, under such a perverted monitoring, you can't get in, even if you do, how much effort does it take? We can't afford to spend time! ”

This doesn't work, that doesn't work, what should I do? Bei Shiliang stopped talking.

Ray shook his head and said, "Let me think about it, let me think about it, there can't be a ...... with a defense that is completely free of weaknesses."

Note: C-C-T-V system is closed-circuit television monitoring system (closedcircuittelevision), is an important part of the security technology prevention system, is an advanced, strong ability to prevent a comprehensive system, it can directly watch all the situation of the monitored place through remote control cameras and their auxiliary equipment (lens, PTZ, etc.), can be monitored at a glance, and provide video for subsequent query and analysis. At the same time, the TV monitoring system can also be linked with the anti-theft alarm system, access control system and other security technology protection systems, so that its prevention ability is more powerful.

It's not our forever glorious CCTV ^O^
