The Nest welcomed its first visitor. Yue'er stood at the doorway, hesitating slightly. The space was excessively minimalist, excessively functional, lacking the warmth and redundancy that human life should possess. Massive data streams surged silently across the walls like cold digital waterfalls, the air permeated with the dry scent of server heat dissipation and a kind of nearly absolute focus. Everything here declared: efficiency supreme, emotions unwelcome. Yue'er took a deep breath, as though swallowing the dry, cold air along with it. She raised her hand to tidy the hair at her temples, the movement extremely light, as if afraid of disturbing the slumbering algorithmic beast in this temple. Her fingertips lingered on the door handle for half a second, the metallic coolness crawling through her skin all the way into her blood vessels, reminding her of the tremor when she first touched minus-forty-degree air in an Antarctic ice core laboratory ten years ago—that tremor came not from cold, but from awe at the unknown territory. The door handle reflected her own eyes, the contracted light spots in her pupils like two miniature black holes, swallowing all emotions attempting to escape.
"Please enter, Dr. Yue." Mozi's voice came from the depths, like a thread woven from binary code, precisely penetrating through layers of server fan hum to reach her eardrum. There was no rising intonation in that voice, no social lubricant like "Was the journey tiring?"—only the most concise imperative sentence, like a line of compiler-optimized code. He stood before the central console, the curvature of his spine and vertebrae exactly matching the 105-degree optimal sitting posture curve recommended in ergonomic literature. Even though he was standing now, it seemed as though an invisible ruler had measured the distance between him and the world. The holographic projection on the console had already lit up, blue-purple light beams cutting countless tiny Tyndall effects in the air, like a silent avalanche. Yue'er noticed that those light particles exhibited extremely brief deflection when approaching Mozi's fingertips—0.3 milliseconds, her brain automatically estimated—that was the interference of his body surface electrostatic field with liquid crystal molecules. This discovery made an almost imperceptible arc appear at the corner of her mouth: so even the "god" of this temple was still composed of flesh and blood, still carrying 37 volts of bioelectricity.
She took her first step, the heel of her high-heeled shoe colliding with the carbon nanotube floor, emitting a 2847-Hertz transient high frequency, like a digitized cymbal. That sound rebounded in the domed space, captured by twenty-seven acoustic sensors, transformed into waveform graphs, displayed in real-time on the auxiliary screen of the east wall. Yue'er knew that Mozi must have seen that waveform—his peripheral visual processing bandwidth was 3.4 times that of ordinary people, a footnote she remembered from reading his 2029 paper published in Nature Computational Science. She deliberately made the landing point of her second step deviate 1.5 centimeters from the first, so the waveform graph showed an asymmetric burr, like a premature beat in an electrocardiogram. This was her signature, her door-knocking brick, her "Hello World." Mozi did not look up, but his left scapula sank slightly by 2 millimeters—she knew he had received the signal.
"I need your data." Yue'er got straight to the point, her voice cutting through the air like a precisely calculated blade. She walked to the console, her fingers dancing in the air, pulling out a translucent silk thread from the void—actually a fiber optic data cable connected to her wrist terminal. "Xiuxiu's acupuncture records, your Hermes Algorithm's high-frequency trading logs, and..." she paused, her eyes behind gold-rimmed glasses reflecting two tiny screens, "your Covariance Matrix model." Mozi finally turned his head, his pupils contracting slightly—an extremely rare physiological reaction for him. He knew that Yue'er was not just a mathematics professor; she was one of the few people who could truly understand his algorithms, even see through them.
"The Covariance Matrix is not yet complete." His voice was still cold, but with a barely perceptible vibration, like a string stretched to its limit. "It lacks a key variable—human emotional fluctuations." Yue'er laughed, a sound like ice cubes colliding in a glass. "That's why I'm here." She pulled up a window, displaying a complex Topological Field Theory model. "I've been constructing a Fiber Bundle model, attempting to describe information flow in high-dimensional space. Your 'anomalous fluctuation'—" she pointed to a point on the manifold where the vector field suddenly twisted into a spiral, "—appears here, like a needle piercing through multiple layers of fabric."
Mozi stared at that point, his quantum terminal on his wrist silently recording everything. He suddenly understood why Yue'er had chosen this place for their meeting. This was not merely a studio, but a temple of mathematics, every symbol on the wall a prayer. He asked: "Can you calculate where the 'other end' of this needle is?"
Yue'er did not answer directly. She pulled up another window, displaying a paper published in Nature Computational Science in 2029. "Stapp Resonance: A Possible Quantum Classical Interface in Biological Systems." The paper proposed a bold hypothesis: that certain macroscopic quantum effects might be amplified through specific biological structures, particularly neural networks with fractal characteristics. Yue'er pointed to a diagram: "Look at this, the resonance frequency of Stapp Resonance—exactly 47 Hertz."
Mozi felt his scalp tingle slightly. He was not unfamiliar with Stapp Resonance; it was a marginal theory in quantum mechanics, like a grain of sand hidden in the corner of an eye. But now this grain of sand had suddenly become a pearl. He asked: "You mean Xiuxiu's silver needles triggered Stapp Resonance?"
"More precisely, it's the 'qi' she speaks of." Yue'er pulled up another window, displaying a complex Topological Field Theory model. "I've been thinking, why did the ancients describe meridians as 'rivers of qi'? Perhaps they intuitively perceived a flow of information, only they lacked the mathematical language to describe it." Her fingers brushed across the screen, and the model began rotating, displaying meridians as tubular structures embedded within the manifold.
Mozi suddenly recalled Xiuxiu's words: "Meridians are not physical pipes, but 'paths' of information flow." At the time, he had thought it was merely a literary metaphor; now he realized it might be a literal description. He asked: "Can your model predict the next 'anomalous fluctuation'?"
Yue'er shook her head: "Not yet. I need more data, especially physiological data during acupuncture." She turned to look at Mozi, her eyes behind the glasses flashing with a nearly fanatical light. "But I can tell you one thing: if this resonance really exists, then it's not just Xiuxiu's needles that can trigger it. Any sufficiently strong information flow, under specific conditions, could become the 'needle' that pierces through the layers of the manifold."
Mozi fell silent. He thought of his Hermes Algorithm, that beast capable of capturing microsecond-level price fluctuations. If Yue'er was right, then his algorithm was not just trading stocks, but was constantly "piercing" the fabric of the market, searching for those brief moments of arbitrage. He suddenly asked: "Can you turn your model into a trading strategy?"
Yue'er laughed, a sound like ice cubes colliding in a glass. "Mozi, you only think about money." But she did not refuse. She walked back to the console, fingers dancing across the keyboard, and a new window popped up, displaying a complex formula. "This is the Chern-Simons Theory variant I've modified, used to describe the 'twist' of information flow in high-dimensional space. If we apply it to the market..." she paused, her eyes fixed on the screen, "we might be able to predict those 'Black Swan' events before they occur."
Mozi felt his heartbeat accelerate. Black Swans were the nightmare of all quantitative traders, those unpredictable catastrophic events that could destroy months of profits in an instant. If Yue'er's model could really predict them... He interrupted his own thoughts, knowing that greed was the greatest enemy of traders. He asked instead: "What do you need?"
"Data." Yue'er turned her head, her eyes behind the glasses shining with a nearly hungry light. "I need Xiuxiu's complete acupuncture records, including EEG, ECG, skin conductance, all physiological indicators. And I need you to run the Hermes Algorithm at specific times, capturing market fluctuations at the microsecond level." She paused, then added: "Also, I need a 'control group'—someone who has never received acupuncture, to compare with Xiuxiu's data."
Mozi nodded. He already had a candidate in mind: Gu Ran, that doctoral student from the physics department studying quantum gravity. He had a clean background, no history of acupuncture, and most importantly, he was sufficiently curious about the unknown. Mozi said: "I'll arrange it. But I have one condition: if this model succeeds, I want 30% of the profits."
Yue'er laughed again, this time with a hint of genuine amusement. "Mozi, you really never change." She extended her hand, her fingers slender and pale, like the branches of a bamboo plant. "Deal. But remember, what we're doing is not just trading, it's exploring the boundary between the quantum world and the classical world. If we succeed..." her voice lowered, becoming almost ethereal, "we might rewrite the entire history of human cognition."
Mozi shook her hand, her palm cold and dry, like touching a piece of marble. He suddenly felt that he was not just signing a business contract, but was participating in a grander experiment, one concerning the nature of consciousness and the structure of the universe. He looked at the projection wall, where the orange manifold was still slowly rotating, those twisted vector fields like rivers of light flowing through the void.
He thought of Xiuxiu, thought of her silver needles, thought of that 0.7-millisecond pulse. He suddenly understood why she had named her clinic "Lingshu Hall"—Lingshu, Spiritual Pivot, the hinge between heaven and earth, the pivot of all things. Perhaps she had long ago perceived what he and Yue'er were now trying to prove with mathematics: that there was a hidden connection between the human body and the universe, a channel of information flow that transcended the limitations of classical physics.
He walked to the window, looking out at the city skyline. The sun was setting, painting the sky in shades of orange and purple, like a cosmic painting. He suddenly felt a strange sense of loneliness, as though he were standing at the edge of a vast ocean, about to set sail for an unknown continent. He knew that what awaited him was not just wealth or fame, but a deeper truth, one concerning the essence of existence.
He turned back to Yue'er, who was already immersed in her formulas, her fingers dancing across the keyboard like a pianist playing a complex concerto. He did not disturb her, only quietly leaving his data chip on the console, then turning to leave. As he reached the door, Yue'er's voice drifted over: "Mozi, have you ever thought that perhaps the entire universe is a vast 'Lingshu Hall', and we are all just silver needles in its meridians, searching for our own 'Deqi'?"
Mozi paused, but did not turn around. He only raised his hand, making a gesture of "see you tomorrow", then pushed open the door and stepped into the twilight outside. The door closed behind him with a soft click, like a period marking the end of a sentence, yet also like a comma, heralding the beginning of a longer story.
He walked down the stairs, his cloth shoes making no sound against the metal steps. He thought of Yue'er's words, thought of that orange manifold, thought of Xiuxiu's silver needles. He suddenly felt that he was standing at a crossroads, one path leading to the familiar world of money and power, the other leading to an unknown realm of quantum entanglement and cosmic consciousness. And he knew, deep in his heart, that he had already chosen the latter.
He took out his phone, sending a message to Xiuxiu: "Tomorrow, bring your needles. We're going to fish a big one out of the sea." He paused, then added: "Also, bring your 'Kidney-interval Moving Qi'. Yue'er says it might be the key to the entire puzzle."
The reply came quickly, just three words: "I'll be there."
Mozi looked at the screen, a rare smile appearing at the corner of his mouth. He put away his phone, raised his head, and looked at the night sky. The first stars had already appeared, twinkling like silver needles piercing through the dark velvet of the cosmos. He suddenly felt that those stars were not so distant, as though he could reach out and touch them, feel their coldness and sharpness, just like Xiuxiu's silver needles.
He began walking, his steps light and firm. He knew that tonight would be a sleepless night, but he did not feel tired. On the contrary, he felt a long-lost excitement, like a child about to open a gift, not knowing what was inside, but certain that it would change everything.
He walked into the night, his figure gradually swallowed by the darkness, yet his eyes were shining with light, like two stars falling into the mortal world. And at that moment, in Lingshu Hall, Xiuxiu was also looking up at the same starry sky, her fingers gently stroking a silver needle, its tip flashing with a cold gleam in the moonlight, like a messenger from another world, about to deliver a message that would change the course of history.
The wind rose, carrying the faint scent of mugwort, drifting between the city buildings, like an invisible thread connecting three souls, weaving them into a net, a net named "Co-creation", about to be cast into the deep sea of the unknown, to capture that fleeting glimmer of truth.
