Qingmu had heard Professor Mei mention the Klein Bottle in the lab when they were discussing higher-dimensional space, but he hadn't paid much attention at the time. He only remembered it as something, but had never imagined what it actually looked like. Now, after Su Huilan mentioned it, he finally formed a more concrete concept in his mind.
"It's not easy to imagine this thing out of thin air, my mind is a complete mess!" Qingmu lit a cigarette, squinted his eyes, and imagined the bottle with no inside or outside, and as he thought about it, it turned into the shape of a chamber pot.
Su Huilan laughed, "Actually, Klein Bottle simulated in three-dimensional space is imperfect because the neck of the bottle needs to pass through the body, which causes some overlap in three-dimensional space. Klein Bottle is even more difficult to imagine than a Möbius strip because it requires gluing two Möbius strips together to get a Klein Bottle, and this gluing can only be done in four-dimensional space. In fact, the best way is to create such a thing in a dream. In dreams, there are no spatial limitations, as long as your imagination is sufficient. I suspect that Felix Klein created this thing in a dream and then proposed it."
"But no matter how rich your imagination is, it can't break through the limits and come up with something that's never been seen before, right? Who has ever seen four-dimensional spacetime!" Qingmu said.
"This doesn't count as breaking the memory limit because it's not true four-dimensional spacetime, but rather a transitional model between three and four dimensions. It only requires a wormhole to connect the inside and outside of three-dimensional space."
Su Huilan glanced at Qingmu as she spoke, "Judging from your expression just now, you must have thought of something. You definitely know about the Klein Bottle, you're just using me to say it. Tell me, what's your idea?"
Qingmu exhaled a puff of smoke, the white smoke slowly dissipating in the air. He took two steps forward, the sound of his slippers dragging on the ground echoing in the cave.
Su Huilan suddenly felt a powerful Mental Power surge from him, enveloping her like a tide without warning, like a man's hand roughly caressing her body.
Ah, what are you going to do?
Su Huilan cried out in her heart, unsure whether she should resist. She didn't understand why Qingmu was doing this. Before, when he used her dream, he was so gentle and refined, letting her hypnotize herself. Why was he suddenly so direct and brutal, without even a word, as if he were launching a sneak attack?
The footsteps continued, clattering like echoes in an empty basement. Su Huilan knew she was nearing the edge of her subconscious; if she didn't resist, she would completely enter the dream state. Apart from the training she received from her father when she was very young, she had never been hypnotized by anyone, especially a man.
This was her first direct contact with Qingmu's Mental Power.
Qingmu's power was even greater than she had imagined. Although she hadn't clashed with him yet, she could feel this power, like a strong bison charging towards you. You knew that the power could easily send you flying without even colliding with him.
She was caught in the vortex of this power—strong, rough, wild... and occasionally, with a touch of special tenderness... It was a strange feeling, like being held by a man, with every pore of her body able to feel his warmth.
ah!
Su Huilan finally resisted, and on the verge of a dream, she built a mental energy shield to isolate Qingmu's Mental Power from her subconscious.
Her cheeks were still flushed, and recalling the feeling from just now, her body trembled slightly, and her heart pounded wildly.
The two Mental Power surged together like a tide, churning violently. At the edge of this dream, within the realm of consciousness, a storm raged, and Su Huilan's consciousness was like a beautiful angel in the eye of the storm, graceful and elegant.
" Qingmu, what are you doing?" Su Huilan asked reproachfully.
Qingmu, a cigarette dangling from his lips, smiled without saying a word.
Su Huilan suddenly felt something was wrong. Qingmu's Mental Power was stronger than she had imagined. If they were to confront him head-on, she might not be able to withstand it. Moreover, she didn't know how much of her will to resist this feeling of her heart pounding.
However, she discovered that although Qingmu's Mental Power was inexhaustible, it wasn't all directed at her; instead, it swirled around her. Intertwined with his power were not only her Mental Power but also another force.
Su Huilan understood. That power was the omnipresent Mental Power that had always existed on the island, but she had almost overlooked it because of habit.
Qingmu used his Mental Power to block this force from Su Huilan's surroundings, creating a mental vacuum vortex centered on Su Huilan.
If Mental Power were visible to the naked eye, one could see a rapidly spinning vortex composed of three colored liquids forming around Su Huilan's body. The innermost red layer was Su Huilan's own Mental Power, the middle green layer was the Mental Power emitted by Qingmu, and the outermost blue layer, though pale, was as boundless as the ocean, permeating the entire space.
The vacuum area in the middle grew larger and larger, and the blue that was pushed out suddenly became more intense, like seawater pushed out by an air bomb, reaching the limit of water pressure, and then began to counterattack, like waves in a storm, surging towards the vacuum area where Su Huilan was, but was blocked by the mental barrier in the middle.
The blue waves crashed against the green wall of force, shattering violently like the lingering smoke of a bomb.
Su Huilan's consciousness could sense this contest of Mental Power, which was more direct and impactful than the three-colored waves we assumed to see with the naked eye.
When the mental vacuum expanded to encompass the entire cave, the power struggles felt in consciousness were beyond description with the word "shock."
The fire on the ground seemed to be affected by this invisible energy wave, with flames leaping upwards as if someone were pulling a bellows underneath it.
Alice felt a little dazed, her mind went blank for a moment, then quickly returned to normal, as if she had just had a nightmare. When she looked at the unconscious Anderson beside her, she realized that she was not dreaming and that it was all real.
The savage on the ground shifted its body and groaned, probably because it had bumped a bone and was in great discomfort.
This was the most powerful battle of Mental Power that Su Huilan had ever experienced or witnessed. The strength of the seemingly ordinary yet omnipresent Mental Power Field on the island far exceeded her imagination, and the abilities that Qingmu displayed were also stronger than she had ever known before.
Qingmu had his hands in his pockets, and whether it was the wind or the heat from the fire, his trench coat billowed. The cigarette dangling from his mouth was still burning, and half of the ash fell gently, swirling in mid-air.
At the center of this turbulent energy, Su Huilan felt increasingly that Qingmu was unfathomable. This enigmatic man! What are you doing?
When Qingmu tossed away his cigarette and lazily uttered his next sentence, Su Huilan finally understood what he was about to do.
"Now you can hypnotize this savage," he said.
