Catherine sighed and stood up, "If there's nothing else to ask, I'll go." ”

"Well, there's really nothing to ask, anyway, you know that the future can't be changed, isn't it, if I have a choice, I still choose to go through everything without spoilers."

"Actually, I don't know the details of the future, such as your deeds, old man, I know that you are the great hero who ended the civil war of mankind, the evangelist, the first saint ......"

"What the hell am I going to do in the future?" Lin Youde was so surprised, "I think it's better for us to have a detailed chat......

"No, that's all I know, you rarely talk about your past adventures, and when you open your mouth, you're having an affair with your harem, so I can't do it if you want me to tell you in detail."

As she spoke, Catherine was about to go outside, but she suddenly stopped after taking two steps, reached out and opened the ventilation duct next to the room, pulling Puran out of it.

"I didn't hear anything!" Puran exclaimed, "I was just passing by while exploring the pipeline!" ”

Lin Youde exclaimed: "Even my perception will be slipped by her as long as I don't pay attention, it's a shame that you can catch her." ”

"Because I still have a lot of experience in catching her." Catherine said.

Puran looked at Catherine inexplicably: "I haven't seen you again." ”

"I've seen it now, okay, go wash it, it's dirty again!" Then Catherine dragged Puran away.

After the hatch closed, Lin Youde glanced at the soundproof force field generator.

Then he still said to Noah in his head: "Through the conversation with her, I have a few questions, first. The last time you took me back, I didn't see me thirty seconds ago. Nor did you appear thirty seconds ago, that is. Your super-civilizations go back in time, and will not lead to the emergence of multiple identical subjects at the same time. Take me back to the past, I will become the past me, but with more memories of the future, right? 】

[Yes.] 】

What would happen if you took me back to when I wasn't born? 】

[It's okay, you'll still be you.] 】

[That means you take me back to when my dad was still in school, and I can call my dad brothers? 】

[Yes.] Because the rule only stipulates that there cannot be two identical subjects of consciousness in the same time and space. 】

[Understand, that second question.] It's also the question I don't understand the most. When you explained the structure of time to me, you said that there was a stable timeline of a supercivilization 'ahead', and I understood that there was a supercivilization in the future, but this supercivilization also exists now, right? So how do you define whether it's in the future or in the present? 】

[This one that exists now is just a shadow, can you say that your shadow is you? Noah asked rhetorically.

What do you mean? Lin Youde decisively took himself for a fool and asked the super-civilization for advice, and he decided that in this way he could obtain a truly accurate definition.

[So, suppose I'm with another super-civilization—let's call it the Pepper Fish Head Civilization.] 】

Lin Youde sent a message to Hiroko: "Today Noah wants to eat chopped pepper fish head. ”

At the same time, he listened intently to Noah's explanation.

[Let's say I got into a fight with the chopped pepper fish head.] I'm at the edge, I'm going to eat it! At this time, the chopped pepper fish head goes back to a year ago, when I just pressed on it......]

[Wait, why a year ago?] What is the number of miles you ride a chopped pepper fish head in a year? 】

[Because I'm so good.] Occupy a position on the timeline for several years. 】

Occupied, occupied?

[Anyway, it went back to the moment I just rode it, intending to change the situation, but it was useless. Because I'm not there, there's only my shadow there. This shadow is part of a fixed timeline, and even super-civilizations can't change this outcome. 】

[I remember that you just encountered another supercivilization for the first time, right? Why is it so sure? 】

[Because I've already summed up the theory.] Encountering other supercivilizations only validated my suspicions. Of course, in the future, I may observe facts that are sufficient to overturn my theory, but until I do so, I can only assume that the theory is correct. 】

[So, the super-civilization ontology only exists for a specific period of time, and the previous timeline is a shadow? Is it part of an already fixed timeline? 】

[You're amazing. Noah said and gave Lin Youde a thumbs up.

[Then I have a third question, what will happen to the super-civilization that fixed the timeline in front of you suddenly goes back to the time behind the time period you are in? Is the timeline in front of you still fixed? 】

[No, in that case, the super-civilization with a fixed timeline becomes me, and there is only the unknown ahead of me.] Noah replied.

Lin Youde felt his scalp tingle slightly: [Let's take a look at the relationship between time and space now, at our current point in time, there are you and the unknown super civilization B, and then there is a super civilization C who brought Catherine back from the future. If, Catherine's current memories of the future will be confirmed one by one, wouldn't it mean that there will be a fourth super-civilization D in the future? 】

Noah blinked before he said, "Yes, you're amazing. I didn't even expect that! 】

Lin Youde half-opened his mouth: [I thought you would never be wrong. 】

[That's because in the past, I was dealing with things that I had experienced countless times. This is a new experience for me. 】

For the first time, Lin Youde felt that Noah was also a mortal, no matter how close to God he was, but he was still not an all-knowing and all-powerful God.

Sure enough, there is no such thing as an all-knowing and all-powerful God.

[Fourth question,] Lin Youde suppressed his sigh and continued to ask, [If there is still a super-civilization D in front of it, and it never intends to come back, doesn't that mean that everything we do will always be doomed? 】

[Huh? Why did you come to such a conclusion? 】

[Because it's moving forward, isn't it?] From a timeline perspective, we'll never be able to catch up with it. 】

Noah turned his head to look at Lin Youde, and didn't even stuff the biscuits into his mouth, and the poker face actually conveyed her thoughts to Lin Youde truthfully: What are you talking nonsense?

It's there, and we'll catch up with it as time passes.] 】

[That's when it stopped at that time, but it will continue to move forward!] 】

[No, it'll be there waiting for us to catch up.] 】

[No, no, the other party has no reason to wait for us, right? 】

[She doesn't need a reason, she just waits.] 】

Lin Youde has one head and two big: [But her time will also go forward!] 】

[yes, what does that have to do with us?] 】

[How can this be okay......] Lin Youde is confused.

Noah sighed.

[You are using the experience of three-dimensional space to describe four-dimensional space-time, but this is not right. It's super powerful, and I'm reluctant to explain it in a way that three-dimensional lower creatures can understand. Supercivilization D in front, in our eyes in the back, is forced to stay in place, but in the eyes of Supercivilization D itself, it is just moving forward normally, and we are moving side by side with him, understand? 】

Lin Youde hesitated and nodded: [It seems to understand a little. 】

[For D, there is no such thing as a "super-civilization ABC of the past", only a super-civilization ABC that exists at the same time as him.] 】

[I think I understand,] Lin Youde had a look of sudden realization, [According to your explanation, suppose, you did not find that the timeline was fixed in the time movement, but kept moving forward along the flow of time until the point in time where D existed, in this case, from your point of view, it was D who suddenly broke into the timeline you were in from other timelines. 】

[Yes.] Noah nodded, [By the way, if I am the only super-civilization in the entire system, there is no such thing as moving between different timelines, because there will only be one timeline. 】

[It can be further deduced that there are as many super-civilizations as there are in the entire system, there are as many different timelines as there are, and ours just happens to have a few different lines entangled. So the question is, what does a supercivilization do if it wants to move to a different timeline? 】

Noah blinked, but didn't answer.

【You...... Don't know? Lin Youde tried to ask.

Noah nodded vigorously and admitted very dryly. (To be continued.) )
