"Safety!"

Drawing a hunting knife from the throat of the twitching enemy, Sergeant Henry Aimee let out a low voice, and several figures dressed in the Wehrmacht's standard tri-colored spotted camouflage quickly emerged from the ventilation duct. The moment it landed, the muzzle of the black hole was already pointed at both sides of the passage.

“...... It's deeper than you think. ”

Tugging at the spider silk attached to her fingertips, the leading girl smacked her lips and glanced at the four corpses lying on the ground motionless.

The corpse was dressed in a gendarmerie uniform, and its equipment was limited to the pistols and submachine guns that were standard for the gendarmerie, in other words, the sentries stationed there in the form of tools. Judging by the fact that they were so lax and easily killed by the invaders, these guys didn't expect anyone to invade here, and they didn't even know what was going on on the ground.

"Is this really the core of the enemy's army? It's too lax, isn't it?"

Sergeant Aimee wiped the blood from his hunting knife, his face bewildered, and his companions showed expressions of disbelief.

They all received special assault education before the battle, made up for the relevant information of the opponent, and then went through a series of endless hell training. This elite assault squad will never despise its opponent and say stupid things such as "In front of our domineering and leaky troops, there is nothing to be afraid of cowardly heresy".

Not underestimating or overestimating the opponent is the right thing to do, but in the face of the elven camp that is progressing at an unusual speed, the commandos are willing to overestimate the opponent.

Because of this psychological factor, coupled with the inherent impression that "the elves are all severe obsessive-compulsive patients", all the members felt incredible in the face of the fact that there were only a few military police guards in the underground facilities. If it weren't for the spiders with their powerful reconnaissance abilities, they would have wondered if the pointy-eared people had set some kind of trap waiting for the stupid intruder to jump.

The spider was also a little puzzled by the situation in front of him, and it was not uncommon for the gendarme uncle to be a sentry in the defense army, but it was a bit of a stretch to say that there was still this uniform model guarding the gate in such a high-priority block as the core area of the Iserlohn Battery. Not to mention whether it is in line with their own military regulations, in such a 40 meters underground, where even a 280mm train cannon may not feel anything, there is a group of incompetent soldiers guarding the important place, and the spider who knows the temperament of the elves also feels unreasonable.

(Is it because all the elites have gone to the front-line fortifications, and there is a shortage of manpower in the rear?Even so, the security level should be raised to the highest level, but-)

As far as the eye could see, there was not a single living creature in the entire passage except for his own group and the four corpses on the ground. Such a sparse security cannot be associated with a "military powerhouse", and it is almost impossible to say that it is some abandoned ruin.

(The only thing that's still a little decent is this underground structure that's deeper and more complex than expected...... Hell it's good to leave even one alive!)

Glancing at the corpse being dragged into the corner, the spider almost couldn't help but hold his forehead and complain.

Charlemagne's information on the underground structure of the Iserlohn Fort is completely blank, otherwise it would not be the spider's turn to lead the team to infiltrate and destroy, so that Valrhona will make a big fuss, and it would be good to hit the vital parts with a single shot, so why bother.

The reason why we were not able to do so was because of a lack of intelligence support.

A complete air blockade, a complete underground of facilities, zoning and information management – all these measures have built a thick intelligence wall for Iserlon, and outsiders have no way of knowing the full picture. In order to overcome his intelligence weaknesses, Roland deliberately made Spider the leader of the infiltration and sabotage team, hoping that her knowledge, experience, and abilities would be useful.

It sounds like a pretty good idea, but in the face of reality and the paranoia of the elves, the above wishful thinking is not worth mentioning at all.

"This is ......"

Walking down the hallway to a row of railings, the spider poked its head out and looked down, holding its breath.

Under the red light of the fort in a state of battle, the dim spiral staircase stretches continuously, up and down, left and right, connecting countless forks and corridors, as if the famous painter Moritz Cornelius Escher's famous painting "Relativity" is a realistic work, or the designer made the Penros staircase into his own composition. Looking at the surrealist landscape in front of him, the spider's face distorted, and the corners of his mouth were hung up and words that he didn't know whether to smile bitterly or get angry.

"These guys, how dare you do it......"

Both Spider and Roland greatly underestimated the paranoia of the elves, and on the basis of ensuring the strength of the underground facility structure, in order to delay the intruders as much as possible, the entire underground block is not only very deep, but not a horizontal hierarchical structure like a beehive, but a block division design made with reference to warships. Each block is not only separated from each other, but also equipped with an airtight explosion-proof gate and a circular pressure-resistant door between the passages, so that even if an explosion occurs in one block, it will not affect other parts. In addition, because it is buried deep underground, even if the 280mm train cannon used by the defense forces hits the ground directly, the underground part will not be shaken. As for Roland's vision, creating a gas explosion to destroy multiple blocks and completely paralyze the battery. In the face of such a design, its practical effect will also be quite limited.

On a theoretical level, there is no conventional means of destroying the Iserlohn subterranean facilities.

"These damn paranoids, don't give anyone a chance at all!!"

Gritting their teeth and cursing, the metal handrails screamed and twisted into a ball, and the commandos couldn't help but look shocked and frustrated when they looked at the bent and deformed metal in the leader's hand.

Just as the team members pondered whether to retreat or ask their superiors for instructions, the spider's eyebrows jumped.

The spider silk that extends deep into the depths of the underground facilities continues to feed back all kinds of information to the spider's senses, and the ground vibration, air flow, temperature, humidity changes, etc., generated by human activities, trivial and messy information continues to flow in, and it is extremely time-consuming and laborious to deal with.

The sound of conversation.

Affected by the structure of the building, coupled with echoes and background noise, it is almost unrecognizable, but the spider silk does not miss the small air vibrations, and after filtering out the noise, it is further revealed that the interlocutor is speaking Charlemagne.

Charlemagne?

For a moment the spider thought she had misheard, and after listening for a while, she could conclude that someone deep underground was communicating in Charlemagne, which was "speaking with a gagged nose", and was not "speaking with phlegm", "only suitable for communicating with horses", and "unique to sewers".

There were Charlemagnes in the Iserlohn Battery, and other troops had successfully invaded? If it was so easy to attack, why would the army red deer kneel down with a shy face and beg the holy maiden to fight, and give the rivals a chance to increase their military exploits? Could it be a foreigner who speaks Charlemagne? It is also impossible, not to mention that this kind of military place will never be open to outsiders, and even if a field observation group from a friendly country is allowed in, the guest and the host will not communicate in the language of the common enemy. Prisoners of war? Don't be stupid, who would set up a prisoner of war camp in a core military stronghold?

After eliminating all kinds of assumptions, all that is left is the inference that spiders would definitely take as a joke on weekdays.

“...... Keep breaking through. ”

There was no hesitation, no thought of retreating, and instead of returning empty-handed and causing the entire battle to fail, the spider was willing to gamble, and it was better than nothing to die, which was a hundred times better than nothing.
