Regarding the Klein Bottle, Aoki had heard the professor mention it when he was discussing high-dimensional space with Professor Mei in the laboratory, but he didn't care about it at the time, so he only remembered such a thing, but never imagined what it looked like. Now after Su Huilan said this, he formed a more concrete concept in his mind.

"It's not easy to imagine this thing out of thin air, my mind is all messed up!" Aoki lit a cigarette and squinted his eyes, imagining the bottle with no inside or outside, and thinking about it became a night pot.

Su Huilan smiled: "In fact, the Klein bottle simulated in three-dimensional space is imperfect, because the bottleneck needs to pass through the bottle, which will cause some three-dimensional space to overlap. A Klein bottle is more difficult to imagine than a Möbius strip because two Möbius strips need to be glued together to get a Klein bottle, and this bonding must be done in a four-dimensional space. In fact, the best way is to create such a thing in a dream, which is not limited by space, as long as your imagination is enough. I suspect that Felix Klein created this thing in a dream and then proposed "

"But no matter how rich your imagination is, you can't push the limits and come up with something you've never seen before, right? Who has ever seen a four-dimensional space-time! Aoki said.

"This is not a breakthrough in memory, because it is not a real four-dimensional space-time, but an over-the-top model between three-dimensional and four-dimensional, and only needs a wormhole to connect the inside and outside of three-dimensional space."

Su Huilan said and glanced at Aoki, "Look at the way you looked just now, you must have thought of something, you must know about the Klein bottle, just say it through my mouth, tell me, what do you have in mind?" ”

Aoki exhaled a puff of smoke, white smoke slowly dispersing in the air, and took two steps forward, the sound of a pull-and-pull mopping echo through the cave.

Su Huilan suddenly felt a powerful spiritual power surging from him, and without warning, it wrapped her like a tide, like a man's palm, caressing her body roughly.

Ah, what are you going to do?

Su Huilan shouted in her heart, not knowing whether to resist or not. She didn't know why Aoki was doing this, she was gentle when she borrowed her dream before, and let her hypnotize herself, but now why is she suddenly so direct and rude, she doesn't even say hello, as if she is sneak attacking.

The footsteps were still ringing, tapping and tapping, like an echo in an empty basement. Su Huilan knew that this was already close to the edge of her subconscious, and if she didn't resist again, she would completely enter the dream realm. Except for being trained by her father at a very young age, she was never hypnotized by anyone, especially men.

This was the first time she had direct contact with Aoki's spiritual power.

Aoki's strength is stronger than she imagined, and although she hasn't fought it yet, she can feel it, like a strong bison rushing towards you, and you know that the power can easily push you up without colliding.

She was in the whirlpool of power, strong, rough, wild...... Occasionally, there is a little bit of special gentleness...... The feeling is peculiar, like being hugged by a man, and every pore of the body can feel the temperature of the other person.

Yes!

Su Huilan finally resisted, and on the edge of the dream, she established a spiritual energy shield to isolate Aoki's spiritual power from the outside of her subconscious.

Her cheeks were still a little flushed, and when she remembered the feeling just now, her body couldn't stop trembling slightly, and her heart was pounding.

The two spiritual forces rolled together like a tide, stirring up turbulently, on the edge of this dream, in what consciousness saw, there were stormy and turbulent waves here, and Su Huilan's consciousness body was like a beautiful angel in the eye of the storm.

"Aoki, what are you going to do?" Su Huilan said angrily.

Aoki took a cigarette in his mouth and smiled without saying a word.

Su Huilan suddenly felt that something was wrong. Aoki's mental power is stronger than she imagined, and if she fights head-on, her strength may not be able to resist it, and she doesn't know how much she has the will to resist this heartbeat.

However, she found that although Aoki's spiritual power was endless, it did not all rush at her, but kept circling around her. Mixed with his power is not only her spiritual power, but also another power.

Su Huilan understood that that power was the ubiquitous spiritual power that originally existed on this island, but because of habit, she had almost ignored it.

Aoki used his spiritual power to block this power from Su Huilan's surroundings, forming a spiritual vacuum vortex centered on Su Huilan.

If the spiritual power was visible to the naked eye, at this time, it could be seen that an extremely rapidly rotating vortex composed of three colored liquids had formed on the periphery of Su Huilan's body. Among them, the innermost red is Su Huilan's own spiritual power, the green of the middle layer is the spiritual power emitted by Aoki, and the outermost blue, although light, is as boundless as the sea, permeating the entire space.

The vacuum area in the middle is getting bigger and bigger, and the blue that has been discharged suddenly becomes rich, just like the sea water that has been discharged by an air bomb, reaching the limit of water pressure, and then it begins to counterattack, like waves in a storm, surging towards the vacuum area where Su Huilan is located, but it is blocked by the spiritual barrier in the middle.

The blue waves crashed against the green wall of force, shattering like the smoke of a bomb.

Su Huilan's consciousness and body could feel that this kind of contest between spiritual forces was more intuitive and impactful than the three-color wave we hypothesized to see with the naked eye.

When the spiritual vacuum area expands to the entire cave, the power confrontation felt in the consciousness is no longer described by the word shock.

The fire on the ground also seemed to be affected by this wave of invisible energy, and the flames rushed upward, as if someone was pulling bellows under the fire.

Alice felt a little dazed, her mind fell into a brief blank, and immediately recovered, as if she had just had a nightmare, and when she looked at Anderson, who was unconscious next to her, she was sure that she was not dreaming, everything was real.

The wild man on the ground twisted his body and chirped, probably touching a broken bone and looking very uncomfortable.

This is the most majestic spiritual power contest that Su Huilan has ever experienced and seen. The strength of the seemingly prosaic but ubiquitous spiritual force field on the island was far beyond her imagination, and the abilities displayed by Aoki were stronger than she had ever known.

Aoki put his hands in his trouser pockets, and he didn't know if it was the wind or the heat of the fire, swinging his trench coat. The cigarette in his mouth was still burning, and half of the ash fell softly, spinning in midair.

Su Huilan, who was in the center of the turbulent energy, felt more and more unfathomable that Aoki was unfathomable. What a man who is a fan! What the hell are you doing?

When Aoki threw away the cigarette in his hand and said the next sentence lazily, Su Huilan finally understood what he was going to do.

"Now you can hypnotize this wild man." He said.
