Do you know what an ant nest looks like?

Take the termite nest as an example, dig it all out and you'll see that it's round and covers about 3 square meters. The nest is lined with ravines and buildings, and its size is enlarged by humans, and it is not an exaggeration to say that the nest is a large castle.

The interior of this castle is incredibly complex, and it is simply a labyrinth. On the outside is a ring of deep ditches, like the ring avenue of the city. Within several ring avenues, there are shallow ravines that crisscross and criss-cross, like the streets and alleys of the city. Both are about four or five centimeters wide. The bottom and sides of the gully are very smooth. The ravines extend in all directions, like thousands of streets and alleys. An ant hill is a social unit of termites. These worker ants lay sand and clay together grain by grain and glue them together with their saliva. When it dries, the "concrete" becomes extremely strong.

And the fifth special unit, the anti-aircraft fortifications hidden underground, is a standard ant-nest building.

In ancient China, there was a tactical phrase called "to store grain for nine years in wartime", and it was under the guidance of this idea that the Fifth Special Force Elite Training School has been digging under the school for a whole decade without shyness! Without the highest level, you'll never understand how many secrets are hidden inside this ant-nest underground structure.

Wind Shadow Building, Lei Hongfei and their group of students followed behind Instructor Mo Tian, passed through the long underground passage, and entered a facility similar to an ordinary underground air-raid shelter. In the sound of the electric motor, everyone was gently inhaling as they watched a steel box more than 50 centimeters thick that could directly resist the close-range bombardment of the anti-tank rocket launcher slowly rise.

They finally saw the main body of the elite training school of the fifth special forces!

Looking at it, even Fengyinglou's heart suddenly rose with an almost pious touch.

No one can imagine how much material and manpower the soldiers of the Fifth Special Unit have invested in this underground military base, and no one can imagine how much time they have invested in order to carve out such a space that can only be described as absolutely vast with their own hands in the underground that is more than 30 meters above the surface.

The entire base is made of reinforced concrete with a thickness of 160 centimeters, and the interior is filled with asbestos tiles with the functions of heat insulation and sound wave absorption, and even if the United States used cruise bombs weighing up to 900 kilograms during the attack on Iraq, it will take repeated bombing to break through the defenses of this underground base.

Thousands of ceiling lights installed on the wall illuminate the entire base as bright as day, and those who sweat like rain on the training ground, mix sweat with unrepentant youth, release them together without reservation, and draw one after another bright trajectory in the air, but also inject unrepentant youth and mission into this underground base, so that this underground building, which has a history of 30 years, still maintains the most surging vitality.

Zhou Yuqi suddenly let out an exclamation: "Look at it! ”

Looking in the direction of Zhou Yuqi's finger, everyone's eyes widened, and a group of trainees wearing special costumes like spacesuits, wearing sealed helmets on their heads, and carrying oxygen cylinders behind them, were practicing long-distance marching around the runway drawn out on this underground base.

The special clothing they wore on each of them, together with the oxygen cylinders and weapons of war, must have weighed so much that every step they took on the hard concrete floor made a heavy footstep. When they ran into the "miniature" desert sprinkled with yellow sand, they left footprints nearly half a foot deep on the soft sand.

Looking at those protective suits that are too exaggerated, if they didn't know that this is the training base of the Fifth Special Force, they would really think that a Star Wars-themed movie is being filmed here.

"That's an anti-nuclear suit."

Of course, Mo Tian knew what the group of students behind him was thinking, and he said indifferently: "Using this kind of protective clothing, you can directly rush into a seriously polluted area, or even a heavily polluted area, after a nuclear bomb explodes or the enemy drops biological and chemical weapons, and engage in a limited armed confrontation with the enemy." In order to improve the survivability of the unit, those suits not only have the functions of anti-biological weapons, anti-chemical weapons, and anti-nuclear weapons, but also have good heat insulation and fire prevention functions, as long as they run fast enough to prevent the oxygen cylinders behind them from being roasted by the flames and exploding, they can even directly cross the sea of fire. ”

"Bang!"

Suddenly, a student wearing a heavy protective suit slammed into a metal pillar next to him, making a crisp sound that shook the audience, and the student fell backwards and fell heavily on the hard concrete floor as if he had been punched head-on. At this time, his movements looked strange, he seemed to be out of breath, he could only shake his head vigorously, and after struggling to stand up with the help of his two companions, he seemed to want to take off his helmet.

But he didn't do it, they received survival training in the nuclear radiation war zone within two hours after the explosion of the nuclear bomb, whether the battlefield is full of nuclear radiation or biological and chemical weapons, it is absolutely fatal to the human body, so the protective clothing they wear is simply fixed directly on the steel plate of the collar with screws, unless there are tools at hand, and there are companions to help, otherwise, they can't untie it on their own.

Watching the student's movements struggling to untie the helmet, Instructor Xue Ningbo's face suddenly showed a slight look of sympathy, but she still didn't say anything in the end. One of the few trainees closest to him, who reached out to help him up, pulled out his brawling saber and seemed to help him twist the screws off his helmet. But the fighting saber was embedded in the gap between the screws, and before he could twist it, a big foot wearing heavy Marine combat boots directly kicked him to the ground and rolled several times in a row.

"What are you doing?!"

The instructor glared at the student who was kicked seven or eight meters away by him, and roared, "Do you know what you're doing? If this is on a real battlefield, you have killed your comrades! I can honestly tell you that even if you help him take off his helmet and nothing happens, I'll shoot you two before you get back to camp!" Because no one dares to guarantee that in the seemingly harmless air, there is no biological virus that can spread quickly among the population and completely lose the combat effectiveness of a well-trained special forces force with rich combat experience in the shortest possible time! ”

The instructor rushed over and grabbed the student who had suddenly fallen just now and was still swaying and acting strangely, and shouted: "I know you were not feeling well this morning, you ran for so long in a protective suit, you vomited to your stomach, you vomited all over your helmet, so full that you can barely breathe." This is normal, let me tell you, in this case, the only way you want to continue the mission and get off the battlefield alive is to gulp, gulp what you just spit out and swallow it back into your stomach. If you can't do it, you will honestly take off your military uniform and leave! ”

A minute later, the student finally regained his composure, seeing this scene, maybe Mo Tian and Xue Ningbo, who had had the same experience, could still look calm, but the students standing beside them felt that their stomachs were constantly surging up and down, and most of them involuntarily twisted their heads, and Zhang Lier and Li Shan, the two female students, were already pale, and they had to twist their clothes with their hands to barely keep their composure.

Of course, they knew what had happened to that senior in this short period of one minute. To tell the truth, if there is only a faint smell wafting in the air now, some of them can't help but vomit!

After running behind the team for about two hundred meters, the student suddenly stopped there again, he was half-kneeling on the ground, without raising his head, and made a "don't get closer" to the people around him, and this time he stood up quickly, only half a minute.

Needless to ask, the student, who was already unwell and suffered a mental trauma because of this, vomited again. Only this time, his reaction was much faster.

If this is one of the reasons why special forces are more resilient than other units and more likely to work miracles on the battlefield, then the price they pay is also too great.

I believe that this student will never forget today, and will not forget what he once did.
