Gate No. 4 is the gate of time and space on Halo Mountain, and several people looked at it carefully, and there was no rune No. 12 either. Zhou Jinyin said: "Bai Zixiong, there is no one on this. In other words, even if this door is good, we can't go home. ”

"That's right," Nobita said.

"If it's good," Zhou Jinyin continued, "we can only go back through his teleportation to the earth in 1945, which is World One, at the bottom of the sea at the southern tip of Kyushu Island, and then to the southwest to Okinawa Island, through the door through which we came out." ”

"You're absolutely right," Nobita said, "and that's the only way we know we can go home." ”

Zhou Jinyin asked, "Are you saying that there is still an unknown way to go home?" ”

Nobita said, "I don't know, because I can't guess until things are figured out. But through my observation, I have a few questions, you may wish to help me analyze and analyze.

"Before we ask questions, let's go back to Gate Four and look at the rune on its base, which represents this world, the Snow Star of 1945. This rune does not exist on Gate 1, which means that Gate 1 of Beacon Star and Gate 4 of Snow Star cannot teleport to each other.

"Since there are 12 runes on each door, and the runes of the Snow Star do not appear on the No. 1 gate, let's call the Snow Star World World No. 13. Now we have three known worlds: the Earth in 1945 was World No. 1, the Beacon Star in Tian Yuan 19 was World No. 12, and the Snow Star in 1945 was World No. 13. Okay, now to start my doubts,

"The first question is, in 1945 in the Earth's No. 1 world, we saw two space-time gates, so does it mean that there are also two or more space-time gates on the Lighthouse Star and the Snow Star?"

"I think it's possible!" Cheese replied, and the others echoed that it was possible.

Nobita said: "I also think it's possible, of course, if it's possible, it's not possible, it's all unknown, so for now, we can only stay at the point of speculation." The second question: If the first question is true, then where are the other space-time gates in the Snow Planet?

"It's a very important question because if we find other doors, we're likely to find our way home. Right? ”

Listening to Nobita's analysis, everyone is excited, what can be more exciting than going home?

"So......" Nobita said, "our next task is to ......"

"Find the door!" Several people answered together.

"Good, that's right, find the door!" Nobita said, "But everyone must also have a mental preparation, that is, there will be a possibility of finding a door, that is: no way!" If there is really no way, then we have no choice but to live here for the rest of our lives. If there is a door, we will find a way to go home, and if there is no door, we will find a way to survive. To live or to die, that's the question, so let's leave it aside for now, and we'll talk about it later.

"Next, there is the third question, which may be far away from us, or it may be impossible for us to solve it in our lifetime, this question is: Who made these special doors!"

"The devil knows!" "Hell knows!"

"Okay, I'll talk about my thoughts," Nobita said, "Personal opinion, just for reference, don't spray if you don't like it, and listen to me: there has been a saying about the three of the universe before, I don't know if you've heard of it." It is that there are three very powerful god-level civilizations in the universe, and it is possible that these gates are built by one of their civilizations, or they are jointly built.

"Why did they build these gates, either to experiment, or to spy on ordinary civilizations like us, or to have fun. But I also thought of the possibility that the builders of these gates might have been cosmic from time to time, but another very mysterious civilization.

"I mentioned parallel universes and bubble universes to His Excellency Archon before, these two universes are only conjectures, they may exist, and I will tell you the details later, as long as you know that whether it is a parallel universe or a bubble universe, they are not with our universe, and quantum communication cannot be carried out. So I think the builders of these doors may be from other universes, in that case, this civilization is very powerful, it can travel between different universes, if possible, we have to close all the portals permanently.

"It's unlikely that all the doors will be closed, but it's possible for other universe builders. Based on this conjecture, my fourth question arises: Have we ever changed history? ”

Zhou Jinyin said: "Didn't you say that our behavior in World War II has seriously changed history? ”

Nobita shook his head and said, "Not necessarily. ”

"Not necessarily?" Zhou Jinyin said, "Why don't you say it may be at this time?" ”

"If the builder of the space-time gate is from another universe, this conjecture is true. Then it is highly likely that our current position is in another universe, which may be a parallel universe or a bubble universe! The world we experienced in Okinawa in World War II and the lighthouse star we came from are not in the same universe at all!

"In other words, what we did in Okinawa yesterday will not change history, because in that universe, everything after 1945 has not happened. For what didn't happen, that's not just what you want to do? ”

"Then according to what you said," Zhou Jinyin said, "the Snow Realm Star we are in now is also in another universe?" ”

"Possibly."

"Oh my God!" Zhou Jinyin patted his head and said. "I'm in a mess."

Several other people were also surrounded by Nobita's chaos. Nobita said: "It's really messy, but it can't be helped, we've been involved." So according to my guess, the irreversible law of time, which was overturned by us yesterday, will be corrected by me again today.

"The fifth question: Does the Beacon Star have any other space-time gates, and the possibility of this question is that after we find our way home, we are teleported back, and we may not come out of Gate One, where? It's not very clear. Based on the fact that Gate 1 is in the Hanging Peak, I estimate that other doors may also be in the Hanging Peak.

"To sum up, one, the irreversibility theorem of time is true and irrefutable. Second, there are other space-time gates in the Snow Realm. Three, we need to find this door and use it to get home. Fourth, none of our actions constitute the crime of changing history or tampering with history. Fifth, I haven't thought about it yet, I'll talk about it after thinking about it. ”

After listening to him, several friends applauded, and Xiaola on the other side of the screen shouted: "Brother Nobita, what you said is awesome, I admire you so much!" ”
