There were two people inside the door, one of them, the fat middle-aged man who had no name all along, but who seemed to have a lot of power, and he was sitting behind a desk, squinting as if enjoying a hard-won break.

As for the other one, Lu Yuan has never seen it, it is a man, he is very tall, and the proportion of his facial features is very large, which makes his whole person show a kind of gloomy temperament. He stood in the corner of the room, looking at Lu Yuan with a smile.

After hearing that the door was opened, the middle-aged man also sat up straight.

"You're coming sooner than you think." He said.

"It's slow enough, I've been delayed on the road for three days, and the time in our world has almost passed for a day, and I'm in a hurry." Lu Yuan said straight to the point: "What about my sister? ”

Along the way, Lu Yuan's biggest concern should be Ah Li, for nearly five days, without eating or drinking, fortunately, Ah Li's IDE body is stronger than ordinary people, otherwise she will definitely not be able to stand it for such a long time.

"Rest assured, she's safe." The middle-aged man said, and then clicked a few times casually on the desk in front of him. A hologram appeared directly above the table, in that picture, it was a place like an operating room, there was a young girl lying on the operating table, her eyes were closed, and if you looked closely, you could see that her eyelashes were trembling slightly, which ordinary people would have before waking up from a deep sleep.

Around the operating table, there are many slender probes carefully helping to rejuvenate the muscles.

"In your world, it may have just been a few days, but you left once in between, and this world has been about 7 months, because I don't know much about your existence in different worlds, how to calculate vital signs, so I asked my friend to protect her." As he spoke, he pointed to the tall and thin man next to him: "I don't want you to give you a corpse when you come back, but the side effect is that this little lady has been sleeping for several months, and it will take some time for her muscles to recover." ”

Lu Yuan glanced at the sinister man with some curiosity.

"Hello, you can call me Doss." The man still had a faint smile.

"Lu Yuan." Lu Yuan also politely reported his name, although the other party should have known it a long time ago.

Sure enough, Doss nodded: "You are a very interesting person." ”

“？” Lu Yuan didn't say anything.

"In this story, you shouldn't have a plot, but now that the Foundation's survival is in your hands, it's interesting, and what's even more interesting is that in your world, you're still restless."

Lu Yuan's brows furrowed even deeper: "So...... What the hell are you talking about? He muttered.

"Do you know Schrödinger?" Doss suddenly changed the subject and came up with such a headless sentence.

"Schrödinger? Is this the name? Lu Yuan was also blinded, in his world, the name Schrödinger has long been forgotten by people, after all, in the years of the existence of the Ark, the productive forces have been replaced by machines, people's experiences have been replaced by virtual worldviews, and Schrödinger's philosophical theory of the fuzzy school is no longer paid attention to.

Doss's smile grew: "Yes, Schrödinger is an Austrian, I don't know if there is still a place for 'Austria' in your world, in short, you can think of this person as a philosopher with some problems in his head." ”

"Oh." Lu Yuan obviously didn't have much interest in this topic, but no matter what this guy said, he was also the one who 'protected' Ah Li, so he still listened politely to the other party's chatter for the time being.

"Schrödinger's most famous theory is chaos, which many people call [quantum mechanics], to put it bluntly, 'things that don't know how to explain at all' can be attributed to quantum mechanics."

"Oh, because no one can understand it, so you can say anything, right?" Lu Yuan painted a groove.

"That's pretty much what it means." Doss continued: "He once came up with a hypothetical experiment, which is to put a cat in a poisonous box, and after 10 minutes, the poison has a 50% chance of killing the cat, and the other 50% chance of keeping the cat alive, so you say, at the moment when the time is up, is the cat dead or alive?" ”

"Huh?" Lu Yuan snorted very depressedly, with an expression of 'what's the problem'.

"Hahaha, that's what's interesting, because from a physical point of view, this cat can only be one of life or death, and must be one of them, but the person outside the box, only when the box is opened, can determine which one it is, so before the box is opened, the cat inside the box is chaos."

"En, thank you for talking about such a meaningful point." Lu Yuan gestured a little impatiently, he was not interested in this topic.

"So I'm thinking, Yao Xiaoxin is not necessarily the protagonist, and where the ending of the story points can only be determined at the moment of opening the box."

Lu Yuan's body tensed suddenly, and he looked at Doss with an incredulous look.

"Yao Xiaoxin?? How did you know the name? ”

He was indeed shocked enough, because this was the world of the Ark, and the people in this world could hardly even detect the existence of the [Ark] itself, let alone the world outside the Ark, of course, let alone know Yao Xiaoxin.

"Hahaha, this expression is very good, you must be thinking 'who the hell am I' right now, right, tsk, this question is quite complicated, I'll tell you when I have time, I just want you to realize one thing."

"What's the matter?" Lu Yuan asked subconsciously.

"Box. Don't you notice that the ark is like a box? Outside of the box, there must be an observer, and most of the time, you players play the role of observer, without which the quest would not exist...... Although we still have our own lives, time is still passing, and society is still changing, we still don't exist. ”

Lu Yuan tried to keep up with Doss's train of thought, but like the cat that existed chaotically between life and death, it was difficult for him to understand the sentence "We still don't exist".

"You mean that the world is only real if the so-called [people outside the box] are observing the world, right?" Lu Yuan asked tentatively.

Doss nodded in satisfaction.

"It's good that you can understand this level." He smiled: "So who do you think is watching you?" ”

Lu Yuan's fists clenched at this moment, the funny thing was that he didn't seem to know why he was clenched, what was it that made him so nervous.

"Do you think someone is watching you?"

"Of course, you're just staring at me."

"No, no, no." Doss smiled: "I mean those people outside the box, those people who have been staring at you since you became [Lu Yuan] until this moment. ”
