It seems that because of this sudden change, the girls named the Three Sages are obviously much more silent than usual, but at this moment, Lin Yumo does not have the extra effort to care about these, being in the enemy camp, of course, he has to race against time to complete his reconnaissance operation this time!

Lin Yumo flew into the air from his hidden mountain peak in the energy Angel Gundam, and continued to advance from the high altitude towards the tower-like ground structure of the alien species, until he entered a place about a hundred kilometers away from the horizontal distance from the structure, and then landed next to the entrance of a crypt that happened to be located here!

Looking inside from the entrance of the crypt, the entire tunnel is slowly extending underground at a small angle, and the inside of this underground tunnel is also very clean and empty, and the walls around the tunnel and the entrance of the crypt are also covered with a layer of black material similar to the tower-like ground structure!

At this time, Lin Yumo did not rush into the deepest part of the xenomorph lair along this underground passage in one go, but cautiously walked inside for a distance before returning to the entrance of the cave.

According to the analysis of the scanning results of the Angel Probe and the direction distribution of the tunnel, the tunnels excavated by the xenomorphs are not linear, but connected to each other in a network.

Lin Yumo speculated that the current tunnel should be able to communicate with the entrances distributed in other locations on the ground, and if you continue to go deeper along this tunnel, it is estimated that you will eventually reach the bottom of the ground structure as part of the core network of the entire nest!

Thinking of the alien xenomorph's habit of liking to burrow underground, Lin Yumo felt even more headache!

You must know that the detectors of the Angel of Energy cannot detect things in the depths of the earth, but the density of xenomorphs found on the surface and in the shallow underground layers alone is as high as nearly 100,000 per ten kilometers...... Lin Yumo felt goosebumps all over his body when he thought about it!

But at this time, how could Lin Yumo allow himself to give up like this, even if it was the Longtan Tiger's Den, he must enter to explore this time, but since the first task this time is to investigate the intelligence of alien aliens, so before entering the underground passage, Lin Yumo first carried out a preliminary analysis and sampling of the surrounding materials that constitute the tunnel!

Lin Yumo held the Angel Gundam and raised the right arm of his body, only to hear a 'sonorous' sound, and the rectangular mechanism equipped on the right arm of the Angel Gundam, that is, the GN Composite Gun Sword Mounted as the main weapon system of the Angel of Energy, bounced out of the inside of the GN Gun Sword Suit.

Unlike the GN Beam Saber, which has a high-heat and high-energy energy blade, the GN Sword installed inside the GN Composite Gun Sword is a solid metal sword made of nano-level special E carbon alloy, even if it is not strengthened by the GN force field, with the power of the Angel Gundam body itself, just a simple swing of the sword can easily cut through the frontal armor of Lin Yumo's original third-generation main battle tank of the world army!

However, just when Lin Yumo controlled the Angel Gundam and slashed at the wall of the xenomorph nest structure, it only made a dull sound like an axe slashing at the trunk of a tree, and the GN battle sword without the GN force field was actually bounced back by the hard wall of this structure, and the sharp blade of the GN battle sword that shone with a silver-white cold light could only leave a shallow scratch on the material that made up this wall!

"The hardness of this material is amazing!!"

Lin Yumo looked at the shallow scratch on the tunnel wall, lowered his head and looked at the GN battle sword equipped in the right hand of the body, and was also taken aback by the amazing strength of this unknown material for a while!

"The strength of the E carbon alloy in my hands can reach this level at most!"

Thinking of this, Lin Yumo couldn't help frowning slightly.

"But is this just the material that makes up the tunnel? Even from the outside, this is a cheap material similar to the condensation of biological secretions, although it is incredible to see a space monster that can live outside the atmosphere, but if you add this surprisingly hard material - the potential of alien xenomorphs is too amazing! ”

Lin Yumo shook his head secretly, there are more ants biting elephants, and now Mars has become a lair of xenos, and fighting them to the death here is purely self-defeating, without the support of the Skywalker mothership, I am afraid that even if I play all my hole cards, I can only fight a draw with the other party at the technical level, as for the final result......"

However, if this time we can obtain some important information about alien aliens in this lair, with the help of the earth base established by Lin Weiren on the earth, and the technology possessed by Skywalker, it is still very possible to confront it.

Thinking about this, Lin Yumo couldn't help but have a deeper idea of returning to Earth as much as possible.

At the same time, Lin Yumo reactivated the GN force field covering the weapon system, and this time, under the reinforcement of the GN force field wrapped in the GN battle sword blade and revealing a hazy pale green color field, the Angel Gundam once again shook off the blade and slashed at the material covered by the side wall of the tunnel!

Unlike the previous tests, this time, although some slight resistance was felt, the blade strengthened by the GN force field still easily cut through the surface of the structure material, and then cut a long, deep incision!

Through this incision, Lin Yumo activated the detector on the body of the Angel Gundam and scanned the fault inside the incision that was cut by the GN battleship, but this time there was nothing new, and all the materials that made up the fault were this kind of biomaterial!

With such a sturdy appearance, this is a veritable xenophobic fortress in a sense!

"Fortunately, the enhancement of the GN force field still plays a role in this material, otherwise, I would not have the confidence to enter the underground facilities here, and under the frenzied density of xenos distributed here, the detection behavior of continuing to penetrate deep into the lair is no different from suicide!"

At the same time, through this, Lin Yumo thought again, since the hardness of the wall material of the nest has reached this level, then if it is used as a carapace on the surface of the xenomorph body, I am afraid it will not be much worse!

From the moment he entered the lair, Lin Yumo had already had the consciousness of being discovered by the aliens, but the other party was likely to have such a strong defensive power, thinking that he might be surrounded by such a group of murderous guys like a tide, to be honest, Lin Yumo's heart was also a little drumming for whether he could escape intact!

"But things have come to this point, and there is no reason to give up halfway, so I can only continue to do so!"

While thinking like this, Lin Yumo waved the GN war sword in his right hand, cut off a small piece of the wall of the xenomorph lair, loaded it into the compartment with built-in armor, and collected it into the body as a sample.

After completing the relevant tests and sampling, Lin Yumo used his GN sword to dig out a hole in the wall of the cave entrance, installed a quantum locator and entered it, and then started the engine of the Angel Gundam again, and flew towards the deeper end of the cave with a low-speed cruise.

The structure of the alien xenomorph underground passage is long and very complex, and if it weren't for the fact that the Angel has reconnected to the quantum network and is guided by the ground positioning function of the Morning Star, it might have been lost like a headless fly, in this chaotic and rugged cavern like a spider web!

"Isn't that a good feeling? Over here...... It's a little too quiet! ”

Yes!

According to the density observed by the xenomorphs before, moving along the underground passage can't hide yourself well at all, and you should have been discovered by the xenos passing in the underground passage a long time ago!

However, since entering here, nearly ten minutes have passed, but I have not encountered any enemies, according to the number of Jù fed back to me by the Morning Star's positioning system, this distance of up to 100 kilometers has allowed me to walk a little half, and the depth has reached 300 meters underground, but the underground passage where I am is has always been so quiet, this is really abnormal!

It's like stepping into a dangerous trap prepared by a seasoned hunter!

"Tsk, that's not good! If nothing else, my actions seem to be exposed! ”

Lin Yumo groaned slightly, and a glimmer of light flashed in his eyes.

"Nope! No, these guys should have discovered my whereabouts a long time ago! Thinking about it this way, it should have been a deliberate bait set by xenos to find an area with a relatively sparse density of xenomorphs so coincidentally. ”

"Humph! I said why the previous invasion went so smoothly to the point of incredible, it turned out to be a ploy to invite you into the urn! However, since they know how to use stratagems, the other party should have wisdom, can it be said that these guys are so confident in their own strength that they think they can eat me when they let me in? It's really underestimated, although these xenos have temporarily acted as hunters, but in the end, who is the prey is still unknown! ”

"And I'm more interested in the fact that I've done a very thorough job of concealment before this, and how did these xenos find out about me in advance? It seems that when I get to the Morningstar, I should also study this unknown detection method of xenos! ”

Thinking of this, Lin Yumo no longer deliberately reduced the flight speed of the Angel of Energy for the sake of caution, and sure enough, when Lin Yumo's movement speed increased, the sensor of the Angel of Energy detected a large number of vibrators moving towards him in front of the cave!
