[The following year, until today, I discovered that this so-called "observer" appointed by my superiors had shelter privileges that were not inferior to mine, that I was able to mobilize security robots, and that he could order them to lay down their weapons. 】

[As for why I found this...... Well, we had a conflict, he asked me for the girl who was crossed out from the list, I asked him to disclose the contents of the experiment, he refused on the grounds of confidentiality, I backed down and asked to confirm the health of the experimenter, which he also refused. 】

[It's too evil! What I found! What did I do! How could he deceive me into doing such a dirty deed! We can't wait any longer, we have to do something. Even if the machine obeys him, my soldiers are still loyal to me! 】

[Today, I organized the security forces, we broke into the laboratory, and found the people on the list inside...... of corpses. 】

[All the people who invaded the laboratory reached a tacit understanding, and kept their mouths shut about the people outside, I found that in the closed environment, people are far more fragile than they think, and they can't be dragged on any longer, we have to get out of here as soon as possible, once we reach the lowest closed environment, we will leave here, the darkness here is simply suffocating. 】

[To exchange the sacrifice of some for the eternal life of another, I refuse to carry out such an order.] 】

The middle of the diary has many pages torn out, and only the first two years of the shelter's closure are recorded.

However, from those words, Xu Yuan still sorted out the information hidden in this diary.

Observer?

Sighing, Xu Yuan couldn't help but wonder if all the shelters were carrying out such experiments that were almost evil.

"Wenwen?" Xu Yuan put down the diary in his hand and took a deep breath.

"Huh?"

"Do you remember your life in the shelter?"

"Most memories are blurry," Xu Ruiwen said, shaking her head and smiling.

"Do you remember a lot of people missing from the shelter in a given year?"

Hearing Xu Yuan's question, Xu Ruiwen couldn't help but shake her head,

"Brother, the experiment recorded in this diary ended in the second year, before I was born."

Xu Yuan was stunned for a moment, and also reacted.

Closing the journal, he got up from his chair.

"It's getting late, and since there's no clue worth keeping an eye on here, it's almost time to go."

Xu Ruiwen was still unwilling, and searched carefully in the director's office, but still did not find any useful clues.

Sighing, her expression couldn't help but be a little frustrated.

"It looks like I ran for nothing today."

"Not necessarily." Xu Yuan patted the diary in his hand, "I still found a lot of useful clues." ”

"That diary isn't necessarily true. Whether it's the location of the diary, or the traces of those alterations, it's too much of a coincidence. Xu Ruiwen reminded.

"I know." Xu Yuan nodded, "But this is our only clue, and then we just need to find that observer, if he is still alive." ”

The whereabouts of the observer are not recorded in the diary.

Or it was recorded, but it was artificially torn away.

If he hadn't died, then the secret of eternal life would have been in his hands.

But thinking of this, Xu Yuan couldn't help but have a headache.

Trying to find such a big living person on the source star is like looking for a needle in a haystack.

Before leaving, Xu Yuan and Xu Ruiwen went to the power room and the hibernation center respectively.

As the two had guessed, someone had come to the shelter, installed new fuel rods for it, and even lived there for quite some time.

It's just that for some reason, or maybe he's already achieved something here, so he left here in the end.

And that's a few years.

After he left, he turned off the power of the shelter, and it was not until Xu Yuan entered the password at the terminal at the door of the director's office that he woke up the sleeping shelter.

"Immortality, or at least longevity, these technologies are part of the interstellar colonization program, although it is not necessary, there are people who have reached here, but they don't know the code of the director's office, so they can't do anything about what is placed inside."

"Can't you blow the door open?" Xu Yuan asked.

According to Chen, the office of the director of the shelter can be opened by violence.

"Unless the design allows it, you won't be able to blow up the room even if you blow up the entire shelter." Xu Ruiwen sighed and said.

Xu Yuan was stunned for a moment, then shook his head with a smile.

"It's so dark."

Whether it's under this kilometer, or this shelter.

Xu Ruiwen bent the corners of her mouth and continued the topic just now.

"But they must have gathered some interesting clues outside the shelter, such as the observer's experiment, and the shelter director's refusal to continue the experiment, including a girl."

"The girl who was crossed off the list in the diary?"

"Possibly." Xu Ruiwen nodded seriously, "After all, she was selected as the experimenter, there should be something special about her." ”

"Observer, is the little girl the only one with these two clues?"

After searching the entire shelter, Xu Yuan did not find the laboratory mentioned in the diary.

Xu Ruiwen carefully recalled what happened when she was a child, and she had no impression of the three words laboratory.

What a horrific experiment the observer had carried out had been taken to the grave with the abandonment of Vault 76.

But in addition to the secret of eternal life, the two found something "interesting" in the shelter.

An experiment-grade quantum computer, and a dismantled soilless cultivation device, and a few gadgets that only appear in the Vault.

Finding a quantum computer here was a complete surprise, and most abandoned shelters are visited by scavengers.

Electronic components and special materials on quantum computers. Can be used as a weapon attachment.

This quantum computer was not discovered by scavengers, it can only be said that it was hidden deeply.

The two then walked around the shelter a few more times, and after making sure there was nothing else useful, they left a mark on what needed to be removed.

With the diary in hand, the two got on the elevator back to the surface.

After pressing the start switch, Xu Yuan raised his left arm and glanced at the time on the GS.

It was exactly six o'clock.

Upon arrival at the surface, several guards immediately greeted him.

"President, if you don't come out again, we're all going to rush in to find you." Seeing that Xu Yuan was safe and sound, Zhao Wei breathed a sigh of relief.

"Is it all this late?" Xu Yuan raised his head.

It's only completely dark, and it looks like it's going to rain.

"What are you going to do with this shelter?" Zhao Wei asked again.

"For the time being, at least a checkpoint and a cemetery must be maintained here." Glancing at the bones all over the ground, Xu Yuan said.

With a slightly grateful smile on her thin lips, Xu Ruiwen on the side looked at Xu Yuan with infinite love.

Ordering Zhao Wei to take five guards to continue to guard here, Xu Yuan got into an infantry vehicle and returned in the direction of the military outpost.

Before dark, the transport helicopter aboard the Constraint will arrive in the area, bringing reinforcements and supplies.
