Global Trial

"What can you do?" The little prince's tone was full of suspicion.

"It is known that the land under our feet can divide, merge, and bend, right?"

The little prince: "What do you mean?"

Xia Mingdong explained unhurriedly: "It means, if I understand correctly, the ground under our feet was straight before, but the people here tried to bend this straight ground into The shape of a ring is formed, and the two ends of the straight line are attached together, which fits perfectly, right?"

The puppet next to him said, "That's right."

"So my premise is that the ground under our feet can bend, merge, and merge and then separate again, right?"

The puppet didn't quite understand, and it became hard to understand. After a while, it said: "Well, we can separate, but after we separate, we are still here, and they are still there, and we still can't meet each other."

Xia Mingdong smiled mysteriously: "It's fine to change the shape after separation and then merge."

"What do you mean?" The little prince couldn't help but uttered words eager for knowledge, accidentally revealing the fact that he didn't know the answer, "What shape?"

"There is a shape, after the evolution from a two-dimensional plane to a three-dimensional figure, we can walk around the entire surface without having to step over its edge, which is what you call crossing the land." Xia Mingdong asked the little prince slowly: "Know What is this?"

The little prince: "... I don't know."

"That's really a pity." Xia Mingdong said with a smile, showing his crooked white teeth. Although he is very small now, the little prince can't see his white teeth clearly, but he can still vaguely see the white dots flashing by. "I thought that the planet from which the trial world came has technology far superior to that of Earth, but now it seems that is not the case."

The little prince looked as if he had been slapped on the face, his face was swollen, but he said unconvinced: "What do you know, the world of trials is not..."

The little prince suddenly fell silent, opened and closed his mouth but no sound came out.

After a while, he shook his head with a confused expression, and asked strangely, "Did I just say something?"

Xia Mingdong was silent for a while, and replied with a smile: "I didn't say anything, you were in a daze just now."

Perhaps it was because the rules of the trial world did not allow the little prince to say anything.

But one thing seems to be certain, the trial world is not some alien high-tech.

"Okay, let's talk about it." Xia Mingdong changed the topic without any trace, "My principle has always been to make bold assumptions and carefully verify."

"What exactly do you mean?" The little prince said dissatisfiedly, "Can you clarify once and for all!"

"Do you mean not to whet your appetite?" Xia Mingdong asked with a smile.

The little prince let out a low "Cut—"

Xia Mingdong suddenly felt that the tsundere puppet boy was a little bit cute, if he didn't fight against him.

Time waits for no one, and he doesn't intend to make a fool of himself. He simply said: "If we disconnect the land under our feet from the connection point, then rotate the land 180°, and finally rejoin the two ends of the land, then the whole The land would become a Möbius ring."

"Mobius Ring?" Ninge asked this time, "What is that?"

Xia Mingdong explained: "The Mobius ring has many interesting concepts. The reason why I can think of this is because of the topic of Lei Gong just now."

He cue the name Lei Gong again, but the little prince seemed to have no reaction to the name Lei Gong.

"That question is a typical two-dimensional to three-dimensional conceptual transition question, and the Möbius ring is also an extension from two-dimensional to three-dimensional to a certain extent. After a two-dimensional plane is distorted in a three-dimensional space, it can reach two-dimensional the other side of the

That question is a clue to your solution to this world, a hint to the hidden mission.

The World of Trials has never had a topic without a reason. Maybe there are other meanings hidden in vampires, blood slaves, and hunters, but he didn't realize it.

Ning Ge pursed his lips and did not speak.

Xia Mingdong continued to explain: "Before, the land under our feet had two curved surfaces, one was the outer ring and the other was the inner ring. If we spliced ​​it into a Mobius ring, then its curved surface would be from the two If you reduce them to only one, it means you can go through. Imagine that you are holding a piece of paper in your hand, you hold one end in your left hand, hold the other end in your right hand and turn it 180°, and glue the two ends together. Together, can you draw a line along the strip of paper and paint both sides?"

The Möbius ring is a very ingenious concept. In addition to the spatial meaning, many people have given it a philosophical meaning.

For example, everything has pros and cons, it is like an endless cycle of reincarnation in the heart, etc...

But Xia Mingdong felt that there was no need to say this here.

Ning Ge lowered his head and thought for a while, and understood what Xia Mingdong meant.

The little prince tilted his head and thought for a long time, and he seemed to understand.

"So the land under our feet can rotate?" The little prince said that he didn't even know.

Xia Mingdong looked at him with a smile: "Don't you know the correct way to crack the hidden mission?"

"I don't know." The little prince muttered in a low voice, "I'm not a trial officer, how could I know that."

"Okay, since you don't know, then do as I tell you." Xia Mingdong commanded simply: "Take us to the place where the two ends of the mainland are glued together, it should be disconnected from there."

The puppet beside him looked confused, "Well, can it still rotate?"

"Since the land can be bent, why can't it rotate? It's all a change of shape." Xia Ming has always dared to think about these things, "Just do it."

"Okay." The puppet was ready to take them there in a daze.

Ning Ge followed behind and whispered to Xia Mingdong, "I was thinking about a question just now."

"what is the problem?"

"The Mobius ring you mentioned, what shape would it be if the two were put together?"

Xia Mingdong smiled and rolled his eyes. He suddenly felt that Ning Ge had a talent for research, and he immediately got to the point.

"Some people have discussed this issue before. Some people think that two Mobius rings can be spliced ​​together to form a Klein bottle."

"what is that?"

"It is a shape that cannot be interpreted or manufactured in three-dimensional space, and only exists in human imagination. The Klein bottle should be a shape formed when the three-dimensional space structure is distorted in a higher dimension, and it is a kind of 'non-orientable. 'Plane, there is no distinction between interior and exterior. Humans can only make conceptual models in the computer, and the modeling is still not correct. There is no such thing on the earth, and the trial world is...not necessarily."

After excluding the alien high technology, he had a feeling that maybe the trial world really had something to do with the earth.

Otherwise, why did all the exiles he met, the aboriginals with status, or the trial officers all bear the shadow of earthlings?

They all have facial features, no matter how rough those facial features are.

And real aliens may not have the concept of facial features, which may be a form of existence that he cannot imagine.

Never let your knowledge limit your imagination.

The author has something to say:

I don't know if I will discourage readers by writing these...

I see most of Jinjiang's infinite streams seem to be horror escapes. Am I too out of place for hardcore science popularization here?

But I still want to write a lot of weird things next...

In fact, the origin of the trial world and the truth behind it have been set since the beginning of my writing

Of course I can’t say it now, haha~
