What are the weaknesses of a large cave base? Lei Dong thought nervously.

Naturally, Lei Dong first thought of a possibility - a power supply system!

The power supply system is one of the most important issues that must be considered before the construction of any modern building can begin. For a large cavern-type base, continuous and uninterrupted power is a top priority. A power outage, even for a few seconds, can paralyze the entire base or infiltrate enemy special forces.

Therefore, these caverns will use double circuit or even three circuit power supply system, in addition to the external power supply, the cavern should also install large diesel generator sets, to ensure that the power will not be interrupted, and the installation of these generator sets of the power cavern, will be built in the deepest part of the cavern base, the safest place, than the deployment of monitoring and alarm system monitoring cavern to enjoy a higher standard of "treatment".

However, the use of diesel generator sets ensures that the base can ensure power supply at any time, but also has great drawbacks. That is, in order to provide enough oxygen for the efficient combustion of diesel fuel in these units, the base needs to open a special vent to the ground, and at the same time, the high-temperature exhaust gas after the combustion of the diesel engine must be cooled and diluted through the water tank, and the unique pungent smell is reduced to a fairly low concentration, and then discharged to the surface through a number of special exhaust gas vents. These two sets of vents must be far away from the vents that provide air for the base staff, so as to prevent the exhaust gas that has just been discharged from the ground from being sucked into the base again, resulting in the poisoning of internal personnel.

In other words, if you find these vents, you will definitely find a passage to the northern part of the base.

Lei Dong turned his head to look at Bei Shiliang and said, "Can you find ......?"

Bei Shiliang seemed to have expected what Lei Dong would ask, and before Lei Dong finished speaking, he shook his head and interrupted him: "I'm afraid it won't work......

Lei Dong was stunned: "Why?" ”

Bei Shiliang did not rush to speak, but directly turned the battlefield surveillance radar and infrared imager to thunder.

"I've observed, their generators, built here!" Bei Shiliang pointed to the picture on the infrared imager and said, there, there is an abandoned No. 1 reactor built near the mountain, where the slight roar came from, and the picture is red.

"it!" Lei Dong was a little dumbfounded at the time, it was obvious that it was the huge heat emitted by the diesel generator, which completely made the imager lose its crosshair. And the most important thing is that in Lei Dong's divine consciousness, it can be clearly perceived that in that area, hundreds of meters underground, there are signs of a large number of people moving - this is also the only place where Lei Dong can feel people. As for the interior of the base, due to the distance and the thickness of the mountain, the divine consciousness that had been invincible before could not penetrate into it, and could not feel anything.

It is clear that the enemy has anticipated that this is the most obvious hole in the base and has made very targeted defensive measures.

Don't give up! The oxygen vent is not working, but what about the exhaust port? Lei Dong searched carefully near the generator set, inch by inch.

Five hundred meters to the left of the vent and about six hundred meters to the right of the base entrance, Lei Dong finally made a discovery. It was a bush in a mountain forest, surrounded by a mess of miscanthus grass. There are more than 20 places in this green plant that the color and state of the miscanthus are clearly different from the surrounding ones, and the withered yellow grass leaves are rolled up into a ball and hang down softly, and even the nearby shrubs are a little wilted.

Got it!

Lei Dong cheered in his heart, the normal growth of vegetation will not appear such a psoriasis-like patch-like wilt, there must be a problem!

Along these withered yellow plants, Lei Dong soon found a hole. There are no obvious traces of axe chisels at the entrance of this cave, it looks like a naturally formed cave, but there is a faint smell of diesel fuel inside, obviously, this is an exhaust port!

But when he saw this hole clearly, Lei Dong was not angry - the diameter of this exhaust port was only less than 30 centimeters, not to mention carrying a huge combat backpack, even if he was stripped naked, he had to practice bone shrinking skills to get in!

Checking more than 20 exhaust outlets without giving up, Lei Dong really has an urge to scold his mother.

There are more than 20 caves of large and small, some are naturally formed, and more are artificially excavated, although the shape is different, but the diameter of the cave entrance is the one that was first discovered, and the smallest is only a dozen centimeters! The use of a large number of exhaust outlets with small diameters, although it may affect the exhaust efficiency to a certain extent, but it brings a great advantage, that is, to prevent foreign enemy invasion, which is much more suitable than laying laser alarms in the exhaust outlets, and simply eliminates the possibility of outsiders entering the base from here - unless you use explosives to widen the hole that I don't know how deep it is, but in that case, the plan to sneak into the base will be completely ruined. You can't infiltrate quietly, and what kind of special operations are you engaged in, just adjust the ground-to-ground missiles and bomb them directly!

it, don't you want to be so outrageous?

Lei Dong's face became heavy. Now things are clear, and there is obviously no hope of success in the assault. If you just attack and destroy the perimeter, not only will it not have any effect, but it will startle the snake and cause the enemy to be highly vigilant, and it will become more difficult to sneak attack in the future.

Or, without firing a shot, quietly withdraw? This choice is not impossible, but not to mention that the task cannot be completed, but the confidence and morale of the brothers alone is a heavy blow.

Lei Dong couldn't help but regret it a little, he knew this, it was better to secretly unload a nuclear missile from the nuclear missile on duty at the base before coming out, boom, the world was quiet......

Looking at the watch, it is close to four o'clock in the morning, and it will be bright around half past five in the season, whether it is to fight or withdraw, a decision must be made, otherwise things will be even more difficult to do as soon as the morning dawns.

If you want to withdraw, you are really unwilling.

If you want to fight, how should you fight?

The problem in front of us is how to sneak into the base two kilometers away, as long as you infiltrate it unknowingly and launch an attack before the enemy reacts, I believe that the chances of completing the mission are quite high.

It's impossible to enter from the sky, if you can order a spell like Tu Dun or something, Tu Xing Sun is the same, go directly into the ground and come out in the center of the base, that feeling......

Wait, Tu Dun? Earth?

Lei Dong's gaze slowly turned to the two shallow ruts, his brows loosened, and his eyes suddenly lit up.

The team members, who are extremely familiar with every action of Lei Dong, immediately realized that the boss had thought of a way!
