After entering the third floor underground, Lin Yue found that it seemed to be much more open than the two floors above.

"It's about 300 square meters up... But this skeleton is really enough."

The light of Lin Yue's flashlight swept the surroundings, confirming the surrounding situation. In order to confirm whether the oxygen was sufficient, he also lit the torch, and the scenes in front of him were indeed terrifying.

He saw that the skeletons were lying prone on the ground one after another, some with various weapons stuck in their bodies, some with their heads flying to nowhere, and some with round holes in their skulls...

The various decorations on this floor are also all kinds of tables, chairs, sofas, etc. There are also things like weapon racks near the wall. There are some knives and guns inserted crookedly on them, but they are not neat. As for the wall of the shelter, it has also changed from the alloy on it to stone, which is a lot rougher. And here, Lin Yue always felt a breeze coming, but he didn't know where it came from.

The light of the flashlight shone into the corner of the room, and he found something different. After Lin Yue walked over, he found an open door. He looked inside and found that they were all neatly arranged single beds. Forty or so.

The single bed was still covered with dust, and in the light of torches and flashlights, Lin Yue found eleven dead bones inside.

Of course, they all have fatal injuries more or less, and in terms of age, they all have sizes.

"Something indescribable must have happened here, it's really tragic." Lin Yue sighed again, there are too many dead bodies here.

There are a total of twenty-seven skeletons on this floor. Their terrifying gestures also made Lin Yue seem to have seen the scene of a tragedy.

"All of them were hit in the key, and some of them should have been shot in the head and died directly." He shook his head. Perhaps, what happened here is not just a tragedy, it may be a more serious tragedy for an unacceptable tragedy.

Looking around, Lin Yue didn't find anything worth noting. This larger area should be the functional area of ​​the house. The upper floor is the warehouse, and the first floor is estimated to be the place to eat. As a shelter, it is indeed planned. Not too good, but safe enough.

However, there are so many bones here...

Looking at the footprints on the dusty floor behind him, Lin Yue once again had doubts about how long it had existed here.

No matter how you look at it, the tragedy that happened here is definitely more than thirty-five days.

Who can drive out of the alloy shelter in thirty-five days? How can such a hidden and deep underground shelter be built? Even an oil extraction and refining platform?

Moreover, the time of death of these people is also a mystery.

But the various evidences at hand are really too little. Although Lin Yue has doubts in his heart, he has no direct evidence to prove the terrible conjecture in his heart.

Lin Yue finally shook his head, walked down the stairs again, and then went down to the next floor.

At this time, a breeze suddenly blew, and the torch in his hand floated in another direction, which proved that there should be a vent that can ventilate outwards, and it also explained the source of the breeze above.

However, Lin Yue didn't care about this. Under the light, he was staring at the space in front of him that was occupied by dozens of wooden shelves, which was much smaller than the upper floors.

The firelight and the light of the flashlight shone on the wooden shelf, and the things on it were actually books!

"Books? And many of them are written in the Tang Dynasty..." Lin Yue picked up a book at random, and found that the cover on it contained the main points of strawberry cultivation. Picking up another book would be similar.

There is a lot of dust on these books, but it seems that because of the humidity, most of the books are deformed, and many pages are stuck together, and there is no value for continued collection at all.

It seems that the people in this sanctuary also went to the secret realm to collect a lot of books, and then made it into a library for the convenience of reading or something.

The torches lit a circle around, and the shelves around were full of books, which really made him feel like he had entered a library.

Lin Yue kept searching forward, the light of the flashlight shone to the deepest part between the bookshelves, and found a dark mass there.

When he got closer, he saw that it was a dead bone sitting on a chair!

This withered body is wearing a trench coat with jeans underneath, and there is a large amount of blood on these two light-colored clothes. One hangs over the armrest of the chair and remains in a leaning position.

"Is that... a pistol?" Lin Yue walked over and saw a pistol lying on the ground below the hand bones hanging outside the armrest. Then he looked at the side of the skeleton with a round bullet hole. !

Lin Yue picked up the pistol and found that it was a revolver type that he had never seen before. Among the six bullets in it, only one bullet was missing. Looking at the bullet hole on the skull, he seemed to understand something.

Does this person seem to have killed himself with a pistol?

Looking at this dead bone, Lin Yue seemed to want to understand something.

So the ones outside, were this done by this one, or was it someone else?

The exit to the shelter is blocked, so...

The tragedy here made Lin Yue almost deduce the whole picture, but there were still some things he couldn't understand.

But what exactly caused this to happen?

The torch suddenly crackled twice at this moment. Lin Yue looked at the flame swaying backwards and walked in the opposite direction of its swaying. As a result, in the corner of the wall, he found a crack the size of a fist, bursts of gloomy coldness. The breeze also came constantly from it.

The gap isn't big, but it's big enough to let something come in and out freely.

Yes, it's the little things in this world that are responsible for decomposition - those bugs and lizards!

Lin Yue looked back at the skeleton, and remembered the situation that was somewhat similar to this before.

The Bergs.

At that time, he saw the skeletons of the Berg and his wife in the underground mine of Berg's shelter.

They obviously didn't die for long, but there was not even a little bit of flesh on their bodies, and naturally there were no other tissues left, only two skeletons snuggled together.

There are also the lizards and beggars who died in the C area of ​​the underground ruins, and they also became a sub-skeleton in a very short time.

The reason for this is that it was eaten up at an extremely fast rate by the ubiquitous and ubiquitous scavenging insects and lizards.

It seems that the reason why these corpses turned into skeletons is probably found.

Normally speaking, in this closed sanctuary, decay is probably an extremely long process, and no matter what, it will leave residues such as hair or nails, but none of these corpses are like this.

I'm afraid, this crack is the entrance and exit of those little bugs and little lizards. After the people inside died and gave off a rotten smell, they also flocked to it. In the end, only the bones were left here. They should leave this crack. .

Lin Yue put on a night vision goggle and pointed a flashlight at it, and unexpectedly found that the opposite of the crack was a rather wide space!

"Where did it lead to?" Lin Yue took out the diamond iron pickaxe and knocked it a few times. The crack quickly turned into a passage for him to enter. After knocking to a depth of less than half a meter, he also entered. this wide space.

However, he suddenly realized that this place seemed a little familiar.

"This torch is a bit like the one in the underground ruins?" Lin Yue looked at a torch on the wall, which was very similar to the one in the underground ruins.

Looking around, the stone brick walls, floors and ceilings are also stone.

The traces of torches on the walls were a few meters apart. Although they were all extinguished, they were quite regular.

Good guy, did you really come to the underground ruins?

Lin Yue took out the sprayer and prepared for battle again. He continued to strap the flashlight to his arm, and then picked up the torch to check around.

A large rectangular space with no exits or passages on the four walls, but…

"What is that?" Lin Yue suddenly discovered that there was a black hole on the ground, two or three meters in length and width, square and square, and one step of steps extended downward.

A sense of sight suddenly flooded into his mind.

Like, have been here?

"This underground entrance seems to be the passage down when I went down to the underground ruins for the first time, and this large space looks like it!"

wait, no...

Lin Yue felt his scalp go numb. This strong sense of sight made him impatiently open the system panel and immediately looked at the regional map.

As a result, it was surprisingly discovered that this is actually the underground relic area F!

And it was the big space he came to when he passed through the stone gate of the underground ruins for the first time!

It's just that this hole is located in another corner, and at that time, I didn't realize that there was a crack on this side.

Good guy, Lin Yue called him a good guy.

Unexpectedly, the actual distance from the underground relic area F to your shelter is actually only a few dozen kilometers?

Moreover, this mysterious underground shelter can also lead to this underground ruins!

Is this a coincidence?

The underground ruins are intricate, mysterious and dangerous.

Lin Yue once imagined how many meters underground the Lizardman's underground ruins would be, but he never imagined that the underground ruins here might be only a few dozen kilometers away from his sanctuary.

The underground relic area F is connected to the underground relic area c and c2 through the ice lizard cave. In this way, it is actually closer to his refuge than expected.

"Could it be that the stone gates of the underground ruins usually appear near the sanctuary? No, that meeting also met Xing Lingfeng and the others, and their sanctuary is much farther than this.

Lin Yue didn't continue to explore. In this place that he stepped on, there was nothing to be missed. After all, he had taken everything that should have been taken, and there were no lizardmen left.

Although new mysteries have emerged, this is not the time to think about it now.

After returning to the shelter, Lin Yue blocked the crack with stone and built a very thick iron wall.

Then, he walked towards the skeleton lying on his back on the chair.

Even if these corpses were eaten clean by the little bugs, the dark yellow color on their bones and the thick layer of dust could not be formed within a few dozen days.

So…

The key to decryption may be near this skeleton, or in this sanctuary!

Lin Yue looked at the skeleton and looked around carefully, but found nothing.

The bookshelves were full of books, and Lin Yue put every book in the storage space, and the system didn't make a special beep, and he kept telling him what the name of the book was.

Naturally, the bookshelves were put into the storage space for nothing. These rotten and deformed wooden shelves are almost at the level of being disintegrated at the touch of a button, and there is nothing hidden.

After putting all the books and bookshelves in this space into the storage space, Lin Yue found nothing on the ground.

Finally, he looked at the dead bone leaning against the chair.

Only it remains.

According to his previous reasoning, a tragedy had happened here.

The corpses on the floors upstairs were all killed by one blow, or their heads were directly chopped off. The methods were quite cruel. Not even one survived. The direction of escape was also the exit. chased and killed.

Moreover, the alloy door of the refuge is locked from the inside, and there is no other exit here, so it is certain that the murderer is among these people.

Among all the skeletons here, the only one that was not killed by someone else was the one in front of him lying on his back on a chair, with a round hole in his head, and the skeleton of a pistol on the ground!

It should be that this man had some kind of illness. After locking the shelter, he had to kill the people inside one by one. In the end, he was left with himself, and then came a self-destruction But...

This may be the answer to the matter, but not the answer to this enigmatic sanctuary.

The degree of aging of their bones, and the dust on the ground, are too strange.

Even if they were really killed from the first day, the skeletons would never have aged to such an extent that they should be gray and white, just like the Bergs.

Perhaps, things will be more complicated than imagined.

With this kind of thinking, Lin Yue looked around the withered bone again.

There was nothing else noteworthy about the chair or its surroundings, and there was no message left on the wall behind.

The rest is this giant withered bone.

Lin Yue observed it carefully, and suddenly found that the left chest and abdomen part of the windbreaker that this withered bone was wearing seemed to be bulging, as if there was something inside.

Lin Yue put on gloves, held a dagger in his hand, and gently scratched the buttoned windbreaker. The rags of the windbreaker were cut open in an instant. I cut it a bit, and soon the contents of the dress fell off.

With a bang, the thing slammed on the chair, and with such a sound, Lin Yue's first impression was a book.

However, after Lin Yue picked it up, he found that it really wasn't a book.

"Diary? Another diary..."

However, after opening the contents, Lin Yue couldn't help but take a deep breath!

"What? How could it really be like this? It's a lie... We, really aren't the first?"
