Su Huilan took a deep breath, slowly closed her eyes, let her consciousness sink into a clear state, and then did what Aoki had just done - dispersing the surrounding spiritual force field.

Her power is not as majestic as Aoki's, but her control is more subtle and delicate. Her spiritual power spread slowly and evenly in all directions, first squeezing the natural spiritual power of the island away from her, isolating a spiritual vacuum centered on herself.

Then, the space slowly spread until it reached Aoki, enveloping him little by little.

Su Huilan had a strange feeling again, as if she was stroking the man. But that man was like an immortal in the clouds, so that she couldn't see her true face clearly, even if her consciousness had penetrated his body.

When the vacuum completely enveloped Aoki, she stopped. Because the mental pressure on the periphery increases sharply with the increase of space, it is like pushing a spring to the bottom, suddenly stopping, and the next thing to bear is the strength of its rebound.

Of course, she could have made the space a little bigger if she had done her best, but she was pretty sure she wouldn't have been able to empty the entire cave just now. This kind of pressure on all sides is really uncomfortable, and the consciousness body feels like it is about to be torn apart.

It wasn't until this moment that Su Huilan didn't know how strong Aoki was and how much pressure he was under just now!

Where are your limits? When she looked at Aoki, she was both admiring and curious.

At this moment, the vacuum has turned into a dazzling white, and the space has disappeared, leaving only her and Aoki. The ground was gone, and the stones, branches, and grass were gone. The fire falls right on the edge of the vacuum, half inside, usually outside. The inside half is gone, and the outside half is still burning.

Aoki smoked a cigarette, the sparks of the cigarette butts and the white smoke were noticeable, but only the outline remained. His whole figure is like a black-and-white sketch taped to the wall.

Su Huilan just wanted to confirm once again whether what happened just now was not the norm here, so she didn't insist on it any longer, after all, it was uncomfortable to withstand the mental pressure of the tide on the periphery.

She retracted her mental power and said, "It's not an illusion, it's really weird here!" ”

Aoki said, "Do you have any sense that the two of us are like two-dimensional creatures just now?" ”

Su Huilan nodded and said, "Indeed, I see you like you're looking at a painting." ”

Aoki said, "When you talk about the Klein bottle, I keep thinking, what exactly is this particular bottle made of? ”

"As I've said before, the Klein Bottle is actually a four-dimensional space, and it has one more dimension."

"No, no, I'm not talking about space. I mean, the bottle should always be made of some material, such as glass, plastic, or whatever. ”

"Hah, how is that possible!" Su Huilan complained, "Glass can only fire a visual model of the Klein bottle in the three-dimensional world, but it is not a real Klein bottle. ”

"But since it's a distorted space, there must be something for it, right?" Aoki says, "What are the usual causes of space distortion? ”

"It's usually mass, which is gravity, and the space around massive objects is distorted by gravity, and light bends when it passes near it, and black holes are the most extreme examples," Su said. ”

"What else?"

"The universe is complex, and there are dark energy, dark matter, and other things that we don't know."

"What about mental power?"

"Mental power?" Su Huilan's eyes lit up, "You mean that spiritual power can distort space and enclose a Klein bottle?" ”

"Why not? If you think about it, our dreams are actually not limited by time and space, and the only rule that limits the dream world is our memory. And the foundation that supports the dream space is the spirit, and the spirit encloses it into any kind of space, and the memory is just the content that fills the space, just like this island. ”

Su Huilan was taken aback: "According to what you say, we are all in a dream now." ”

"Quite possibly! It's just that I can't figure out who is so powerful that he can make such a dream. ”

Aoki has taught Kitano Masatake the group real-life dream that he has arranged, and it still exerts unimaginable power more than seventy years later, but the space on this island is much larger and more magical than that cave in southern Yunnan, and the key is the ubiquitous spiritual force field on the island.

Su Huilan shook her head and said, "I don't think it's possible, before we went to the island, but in the vast Pacific Ocean." ”

Aoki smoked a cigarette and suddenly spit out two smoke rings. The smoke ring is round, slowly spreads through the air, and then merges together and becomes a cloud of fog.

"Is it possible for the Klein bottle to be broken down into two Mobi rings?" He asked with some certainty, it was really hard to remember something named after a scientist, and his memory was sometimes good, sometimes messy, sometimes he could remember something inexplicable, and sometimes it was blank.

"It's a Möbius belt, not a Möbius ring." Su Huilan corrected, "Theoretically, two Möbius strips can be spliced into a Klein bottle, what's wrong?" ”

Aoki said: "Is it possible to understand it in this way, assuming that this spiritual force field from nowhere constitutes this space similar to a Klein bottle, then when we use the spiritual force to line up the force field, this Klein bottle is decomposed and becomes two Möbius belts. The Möbius strip is flat...... So you see me like a painting on the wall."

Su Huilan was suddenly surprised again: "Because we have become two-dimensional creatures on the Möbius belt?" This...... It's terrifying, isn't it? ”

"Maybe what we're seeing is a three-dimensional projection of us on a two-dimensional plane, or maybe we're just seeing a projection of our consciousness," Aoki said. ”

"That'...... What about our flesh? Su Huilan asked.

"I don't know." Aoki shook his head.

Academically speaking, Su Huilan is an authentic professor, and her scientific literacy is much stronger than Aoki's, but in such an environment, the higher the scientific literacy, the easier it is to be unconfident, but Aoki can think crankily without having a sense of guilt for blaspheming sacred science. Moreover, after being in contact for such a long time, Su Huilan has realized Aoki's ability, people are born with a dependence on the strong, especially when facing the fear of the unknown.

When Aoki came up with a very absurd but reasonable explanation, Su Huilan's rationality gradually recovered. As she pondered, she said:

"Captain Church's diary describes how the Discovery was once lost at sea, and that they had encountered a heavy fog and had been at sea ever since...... They may have entered a Klein bottle like us, but they kept spinning on the curved surface of the bottle, so they were in the sea all the time, unable to find a place to stay, and they may even have passed through the wormhole of the fourth dimension along the bottleneck until Christmas a few months later. ”

"The curved surface of the bottle?" Aoki looked up, as if he had seen through the dark brown stone at the top of the cave illuminated by the firelight, and saw a large bottle standing in the void above the Pacific Ocean, "So they are likely to be above us?" Well...... The coal boss flew upwards, also hit the belly of the bottle, and then slid down the bottleneck to the bottom of the bottle - the lake! So why didn't it go a few months later? ”

Su Huilan said: "It may not pass through the wormhole, but just slide down the surface of the bottle, and the position of the four-dimensional space corresponding to the three-dimensional space-time is not fixed, and the space-time point that it falls to may be different every time it crosses." ”

"Oh, I was wondering if I could time travel and get everyone on the ship back!" Aoki sighed.

"Of course it can't be!" Su Huilan said with great certainty, "It is impossible for parallel universes to overlap, and what you save must not be this world." ”

Aoki also thinks it's ridiculous, and although he doesn't agree with the parallel universe view, he no longer wants to save the whole ship.

"But get Mrs. Larry out!" He exhaled a long puff of cigarette, his tone lazy, but with undeniable determination.
