Lu Fan, who was in a hurry to see what was going on, didn't care about exposing the Silver Wing, parked the mecha in the aircraft pile, and after choosing a relatively hidden location to hide, he jumped out of the mecha hatch and walked towards the elevator door.

As soon as he arrived at the door, the metal door opened silently, revealing a bright space that could accommodate twenty people, Lu Fan entered the induction elevator, chose the floor closest to the energy gathering point, and pressed the start switch.

The induction elevator vibrated slightly, and Lu Fan could see from the display screen that the floor he wanted to choose had arrived, and at this time, Lu Fan immediately adjusted the energy in the group and entered the shadow form.

The elevator door opened, and Lu Fan entered a huge space that was almost enclosed, and the dim light made it impossible for Lu Fan to determine the size of the space, in fact, in the Gray World Realm, there was already no reaction of energy points here.

Walking into the space, Lu Fan could smell a pungent odor, the smell was emanating from some white objects sprinkled on the ground, squatting down to take a closer look, Lu Fan noticed that the messy white object was actually a biological bone, much like all in the body of a bird, with a little minced meat residue on it.

It should be said that there are obvious gnawing marks on the piles of bones scattered on the ground, and it is inferred that these are food spit bones abandoned by those scattered creatures.

The empty enclosed space, the dim environment, and the spitting bones of these randomly thrown food on the ground, all kinds of signs show that they do not look like civilized people, that is to say, the black-haired figure that Lu Fan saw is really not necessarily human.

Of course. The signs that Lu Fan saw cannot be completely denied that they were not done by human beings, and when they are avoiding major disasters or wars, civilization will fade with the environment, and human beings will survive in order to survive. They will also live a blood-drinking and fur-drinking life like cave savages.

Near the pile of spitting bones on the floor of the dim hall, Lu Fan at least found signs of fire roasting, proving that the creatures who stayed here. It's not yet to the point of being eaten alive.

In the entire hall, except for a few piles of bones that had been thrown in the corners, there were only a few messy food packaging bags. I didn't see anything out of the ordinary, and I didn't find anything else usable.

On the contrary, it was Lu Fan's gray world realm, which fed back to the energy points that were originally scattered and far away, but at this moment, they all stopped, and seemed to have returned to the real hiding place, and the black-haired figure that Lu Fan had been following had already come to the depths of the underground of the building, and gathered with the five energy points, and there was no sign of movement.

Lu Fan looked around, the square hall. I can't see any other entrances and exits, it seems that only the elevator that Lu Fan took down can use, but those energy points that converge in this hall are indeed leaving from here, and Lu Fan is coming down. It has been noted that the elevator has been staying on the floor where the lobby is located, and has no access to other floors.

After wandering around, he found some hidden strangeness in a dimly lit corner, and in order to prove his theory, Lu Fan deliberately took the elevator a few times again, going in and out. They all lead to the normal floor halls, and the interior is a mess, with no signs of human activity in sight.

Returning to the dim hall, Lu Fan walked into the strange place he had discovered earlier, close to the corner wall, which seemed to be one and the same, and seemed to be no different from other walls, in fact, judging from the reaction structure of the internal metal support, there was another mystery in it.

The vertical secret passage leads from the mezzanine of the wall to the underground, and the entrance is disguised as the same color as the wall of the hall, if it were not for Lu Fan's gray world, it would be difficult for others to discover the mystery.

I groped the wall near the entrance with my hand, and it was smooth, there was no switch tunnel, and I didn't find the location where the sensor was installed, and if I flicked my fingers, I could hear a dull echo, which proved that the wall was hollow, as for the entrance switch, Lu Fan suspected that it was not nearby, it might be controlled by an underground hideout, or it could be hidden in a dark corner elsewhere in the hall. …,

Lu Fan wanted to look elsewhere, but when he got up, he inadvertently supported the wall with his hand, and when he landed on his hand, he suddenly slipped away silently, revealing a deep and secluded opening, which was so black that he could barely reach out and lose his fingers, and he could still feel the cold wind blowing in the passage on his face.

There is an air outlet, which means that there is another opening to the outside world in this exposed passage, and of course, the ventilation duct is not excluded. Lu Fan tried to take a breath, the air inside was still very fresh, not like the dull smell of a closed space.

However, Lu Fan did not see the existence of the elevator and the means of passage, and only found a long metal pipe against the wall inside. It leads from top to bottom to the ground floor of the building.

What are the considerations for placing such a long metal pipe in the mezzanine of the building, before the building was built, or after the Great Migration?

Lu Fan didn't want to turn on the light source to find out, first, for fear of alarming those energy points and causing unnecessary misunderstandings, and secondly, the construction of the metal long pipe, what period it belonged to, now it doesn't matter, on the planet occupied by the Zerg, there is such a group of creatures with unknown origins, hiding in the mezzanine of the building, this thing itself is full of weirdness.

Whether to wait or follow the passage to enter, Lu Fan thought about it for a while, because he couldn't judge the form of the hiding place underneath, whether there would be the possibility of the rest of the passage, so Lu Fan was worried that he would have to re-track it when the time came, wasting unnecessary time, it was better to enter directly.

Because Lu Fan was still in the shadow form, he was not worried that he would be discovered by these hiding creatures, coupled with his strong physique, he just grabbed the metal pipe with one hand and slid down.

The hall before the jump was about more than 20 floors of the floor, so after Lu Fan jumped down, he arrived at the bottom floor, and in the blink of an eye, the high-speed landing impact was reduced a lot by Lu Fan with one hand and one hand when he was close to the ground, until Lu Fan stepped on the ground, it did not cause any sound.

The environment of the landing is also dim, but there are faint lights flickering in the distance, through the faint light transmitted, Lu Fan can clearly see that the place he is in now is actually an underground transit in all directions, silently counting, there are six passages with lights, and the passages that fall into darkness are also six, twelve passages, forming the connecting branches of the underground world.

The black-haired figure that Lu Fan was tracking was now counting the end of the bright third passage on his left hand, and he passed through the transit place, at least two kilometers away, so he couldn't see the details of the inside clearly.
