Zhang Yide judged that the woman on the ground was a robot, not a humanoid girl, entirely because the system had speculated that there was an autonomous machinery maintaining the shelter during the month.

Therefore, the moment he saw that the 'woman' was a mechanical structure in his body, he classified the woman as a robot.

Of course, even if he thought so, he still asked Amy to help check it out in a cautious manner.

Amy's move was very simple, she walked out of Zhang Yide's body, stretched out her translucent little hand to poke into the woman's head on the ground, then withdrew her little hand and said: "That's right, pure mechanical structure, no human brain biological tissue, no soul remnants, but about the last point, because I can't tell how long she has been dead here, so I can't tell if she has a soul when she is alive." ”

There is no air on the moon, including in this passage, and naturally, the dust and bacteria that will accumulate on the corpse from the air circulation are non-existent.

Therefore, if you want to see how long this woman has been 'dead', the ordinary means of examination are useless and it becomes difficult to judge.

"Well, I see, I'm sorry for you. ”

Zhang Yide nodded, he knew that there was only so much Amy could do, and after letting Amy return to his body, he carefully examined the corpse again.

In addition to the brain and body skeleton of this corpse, which are purely mechanical, the bionic skin on the outside is not the dermal tissue used by Zhang Yide and the Hell Flower Organization, but a kind of skin tissue that seems to be the same as a real person, but is actually a synthetic material.

This skin tissue is very tough and seems to be soft, but in fact, Zhang Yide took out a green quality dagger to test, but he failed to cut through this layer of epidermis.

This also proves from the side that this female bionic robot is powerful.

Although this female bionic robot has no energy now, and her strength level cannot be measured before her death, but only from the perspective of defense, she is at least at the level of a third-order monster.

Bionic robots at this level, even if they are placed on today's earth countries, are a very strong combat power, second only to the top battle girls with force field energy.

It seems that the potential danger of the Moonhouse is not to be underestimated.

Zhang Yide scanned the body structure of this bionic robot with his mobile phone, and after including the blueprint in the database, he stood up and said to several Zhan Ji around him: "Let's move on, everyone should be careful and vigilant." ”

"Rest assured. ”

"No problem, leave it to Jiujiu!"

Thorns and Ninety-Nine responded one after another, and then everyone moved forward again.

More than 100 meters later, everyone came to a gate without any danger.

The door at the end of the passage was a metal door that could be raised and lowered automatically, but at the moment the door was broken, revealing a large opening, the edge of which was jagged and jagged, as if it had been violently broken by something.

The thorn who walked in the front grabbed the dagger directly, carefully explored the gap, and after a while, she beckoned to everyone inside, and said, "Safety, come in." ”

Zhang Yide bent down slightly and walked in through this gap, while Jiujiu took a step later and came in behind Zhang Yide.

As soon as he entered the real space of the shelter within this month, Zhang Yide realized that he had underestimated the magnificence of this shelter before.

He saw that this entrance space was extremely large, at least more than 100 meters high, and at least more than 300 meters wide, which was equivalent to a huge square, and on the side of this huge square-like space, there were layers of metal structural layers like floors, and there were some take-off and landing stairs at the edge of the structural layer that had not yet shrunk back, and these stairs led to the outside space, which seemed to be used for the entry and exit of aircraft personnel, but now there is no aircraft here.

Here it seems to be a hangar?

Zhang Yide thought of this possibility, and only this possibility could explain the purpose of this huge space, and when he looked back at the wall bordering the outer rock of the moon behind him, he found that the huge metal wall on the outer layer of the shelter was not decorated at all, and it was completely different from the architectural style of the hangar space inside, as if the outer metal wall was added from behind.

"The re-installed shell.... Or...."

Zhang Yide walked to the wall and knocked on it with his hand, and after a careful look, he found an astonishing fact, that is, the huge metal wall of the shell has no gaps at all, it seems to be made of one piece, although there are broken gaps in some places, but at least in addition to these violently destroyed gaps, the other parts of the metal shell are so perfect.

"Is this the technology of the last generation of civilizations, it's really terrifying. Zhang Yide sighed, perhaps, at least this level of technology, in order to resist the invasion of the Chaos Abyss.

"BOY, this way!"

Suddenly, Thorn shouted in the distance, which made Zhang Yide quickly shift his gaze.

He saw that the thorn was at an entrance and exit two hundred meters away, and there, there were some debris and debris on the ground.

His goggles stretched and enlarged the debris and debris on the ground in time, which allowed him to see the details clearly, it turned out that those debris were all severed limbs and body fragments!

No, to be precise, the severed limbs and body fragments of the shelter's autonomic robots!

Zhang Yide clearly saw that inside a severed hand, there were broken mechanical bones and some bifurcated lines, which was enough to prove the identity of these severed limbs.

Zhang Yide walked there quickly, and soon he saw more details, the alloy floor here had many traces of battle, small pieces of clothing and the body remains of some autonomic robots scattered everywhere, as if there was an extremely tragic battle here, and there was not even a single autonomic robot that could leave a whole corpse.

But the strange thing is that there is no corpse residue of their enemies here except for the wreckage of the autonomic robots.

“......... It seems that the enemy must be a mutated monster above the third order. ”

Zhang Yide sighed, only the mutated high-level monsters will gradually decompose their bodies after death, turning into gray mist particles in the air, leaving no corpses.

"BOY, THERE'S STILL THIS. "Thorns beckoned at the entrance to the passage, which was very wide, probably for vehicles or some small warplanes, like a small tunnel, but the entrance to the tunnel was not covered, not even a door.

Because Zhang Yide can only see things through the night vision black and white vision of his goggles, he is not very sensitive to the details of distant objects, like now, the thorns reminded him, and he can notice again that there are some debris in the mouth of the tunnel, and those debris is actually the corpse of an autonomous robot......

Zhang Yide walked into the tunnel and found that these self-discipline robots were supposed to protect the tunnel from being entered by the enemy, but they failed, they were torn here one by one, and the corpses were all over the place, there were self-discipline robots with male appearance, and there were also self-discipline robots with female appearance, and even the physical characteristics revealed under their torn clothes were similar to real men and women, but no matter what their appearance, in the face of death, they were no different.

"Based on the number of bodies put together, the number of these dead robots is about thirty. ”

Thorns experienced reported her findings, which made Zhang Yide nod and said, "It seems that there are not a lot of autonomous robots in this shelter, huh? ”

Zhang Yide saw at this time that there was a strange death of an autonomous robot, the female appearance of the robot died with her hand raised towards the wall, but it seemed that the enemy nailed her to the ground directly from behind, so that she could only raise her hand in vain, and finally lost all her strength and died there.

Is there anything in the walls?

Zhang Yide walked over quickly, scanning the wall there with goggles, and soon the goggles found a glass plate embedded in the wall in the dark, this glass plate is about one meter six high, and the size is equivalent to the size of a tablet computer about ten inches, which makes Zhang Yide realize that this non-reflective glass plate is likely to be a display device for some kind of terminal measure.

He approached the glass plate, pressed it lightly with his hand, and there was no reaction, it seemed that all energy had been lost here, not to mention this glass plate, even the entire tunnel, and even the huge hangar outside, there was no energy at all, it was pitch black, as if this area had been completely dead.

He thought for a moment, took out his phone, and pressed it against the pane of glass.

"The system, can it be linked to the information link behind this terminal?"

The system replied directly from his helmet: "No, no data information can be detected, the link has been physically isolated." ”

Zhang Yide was slightly disappointed: "Is it physically isolated? Okay." ”

Now that the line here has been cut off, there is nothing he can do. He could only greet the warrior concubines around him: "Let's go, let's move on." ”

Now I can only go deeper, hoping to find some electronic circuits that can be used, or more useful items.

However, since a large number of autonomic robots have died, he must not be far from finding out the truth.

He kept his vigilance and followed the two battle queens forward, this tunnel was a bit long, but everyone present was extremely physical, and it was still trivial to walk such a way, but after a while, everyone actually encountered a metal wall.

This metal wall appeared abruptly in the middle of the tunnel, not like a door, but more like it was made here improvly, trying to block the place.

Of course, this act of blocking was a failure, because a large hole was violently broken in the middle of the metal wall, the hole was two meters seven high, four meters wide, and the edges were irregular, and I don't know what kind of monster opened such a big hole and broke through.

Zhang Yide didn't rush through the big hole, he first walked to the metal wall and took a closer look.

The material of this metal wall is strangely the same as the huge metal shell of the outer layer of the shelter.

Well, to be precise, it's roughly the same, Zhang Yide reached out and knocked on the metal wall, according to the data of the nano combat suit auxiliary computer feedback, the material of the metal wall is still a little different from the material of the shelter shell, at least in terms of strength, it is a few percentage points weaker.

"Is it a process problem, or is there a shortage of some important material?"

Zhang Yide said softly, and then he temporarily suppressed this question in his heart, and walked towards the big hole, and after passing through the big hole, he saw more autonomic robot corpses.

This time, at least sixty autonomous robots died in the tunnel behind the metal wall.

"There are more autonomous robots in the shelter than I expected, and the battle is far more intense than I imagined. ”

Through the corpses and destroyed sites that he had seen along the way, Zhang Yide could easily imagine that the monster had originally entered through the metal door of the outer passage, and then caused a big battle in the hangar, and even the huge metal wall on the outer edge of the hangar was pierced by the other monsters that came immediately after him, and broke in.

The monster has reinforcements, and the hangar is lost.

The autonomic robots left a lot of corpses on the hangar, and built a metal wall in this place to try to fend off the monsters again, but unfortunately, the place was lost again, and the autonomic robots left more corpses....

Even just looking at these corpses, Zhang Yide could tell how much the autonomic robots wanted to keep those monsters out and not allow them to break into deeper areas, but unfortunately, their strength seemed to be weaker than those monsters.

"Let's hurry up and go inside and have a second look, hoping to see the robots that are desperately resisting. ”

Zhang Yide ordered, and then the group accelerated their speed.

After walking more than 200 meters, suddenly, the thorn at the front of the team stopped.

She raised her hand and said, "Be careful, another enemy is coming." ”

At the same time, Amy's voice also sounded in everyone's heads: "One of the targets is the monster that attacked us just now, and the other two high-energy reactions, it has found a companion to attack us together!"

Hearing this, Zhang Yide immediately took a few steps back, concentrating, and was about to activate his colorful shield at any time, and soon, he heard the sound and saw that deep in the tunnel ahead, there were three hideous monsters running over!

He saw it, and it also meant that the Thorn Jiujiu and the others, who were war concubines, saw it, even more clearly than he could see!

The three hideous monsters all looked like deformed human mutations, and the tips of each monster's hands turned into long white bone spurs, and one of the monsters had shorter bone spurs, which seemed to have been broken not long ago, and were rapidly growing back.

That's right, these are the three!

Jiujiu's eyes widened immediately: "Why didn't they sneak up on the wall this time?"

"Fool, the walls here are pure metal, unlike the outside! Raise your claws and prepare to meet the enemy!" thorn scolded.

Reminded by the thorns, Jiujiu immediately ran a few steps forward, standing on the same line as the thorns, to meet the charge of the three monsters.
