It began quietly, on an ordinary day among ordinary people. Students sat through lecture rooms, office workers stared at glowing screens, doctors moved through hospital corridors, and families gathered for dinner. Nothing seemed different. Yet across cities, campuses, offices, hospitals, and private homes, something strange had already appeared—black envelopes resting silently where they should not have been.
No one saw who delivered them. No courier knocked on any door, and no security camera captured their arrival. They had appeared on desks, bedside tables, lockers, and doorsteps, as if they had always been there waiting to be noticed.
Across the world, the same moment repeated itself. Someone would notice the envelope, hesitate, and pick it up, wondering who had sent it and why their name was written across the front in elegant gold lettering. What none of them realized was that the moment the first envelope was opened, the ordinary world they knew would begin to unravel. But none of them knew that yet.
—————————————————
The lecture hall of Hangzhou University's Behavioral Science Department hadn't been this crowded in years.
Rows that normally held half-attentive graduate students scribbling reluctant notes were now packed to capacity. Every seat had been claimed long before the lecture began. Some students perched along the stair railings, balancing notebooks on their knees; others stood pressed against the walls, unwilling to miss a single moment of what was about to unfold.
Even several professors had slipped into the back rows, pretending to review papers while their attention was entirely fixed on the stage.
At the center of it all stood Shen Wuyou.
At first glance, he seemed almost fragile—slender, pale-skinned, with dark blonde hair falling in loose strands over his forehead. His quiet expression suggested someone who observed more than he engaged, as if the world beyond the lecture hall existed at a comfortable distance. He looked less like a renowned prodigy in behavioral science and more like a student who had accidentally wandered onto the stage.
But the moment he began to speak, the room fell completely silent.
Behind him, the projector glowed, displaying a single, precise title:
Behavioral Pattern Recognition in Crisis Systems
Shen Wuyou held a small laser pointer lightly between his fingers and shifted toward the screen, his movements controlled yet unassuming. Every eye in the room followed him, every ear attuned to the first words that would soon unravel a world of observation, analysis, and insight that only he could deliver.
"Imagine," he began, his voice calm and measured, "a confined environment with limited exits and limited resources."
A small red dot glided across the diagram projected behind him, tracing the paths of movement within the space.
"Ten individuals enter at the same time. None of them understands the rules of this environment. They know only one thing."
He paused, letting the words hang in the air. The silence in the hall thickened.
"Someone will die."
A few students shifted uncomfortably in their seats. The statement was simple, almost clinical—but the weight of it pressed down on the room.
"Who do you think survives?" Shen Wuyou asked, his tone casual, almost detached, yet every ear strained to hear his next word.
A hand shot up immediately in the third row.
"The strongest person," a young man said with confidence.
Shen Wuyou tilted his head slightly, regarding him with a quiet scrutiny.
"Incorrect."
Another hand rose, this one from the opposite side of the hall.
"The smartest?"
"Nice try, but also incorrect."
A girl near the aisle leaned forward, her brow furrowed in thought.
"The one who adapts fastest?"
Shen Wuyou studied her for a long moment. Then, almost imperceptibly, a faint smile curved his lips.
"Closer."
He clicked the remote. The slide shifted, revealing the next stage of the scenario, and the room seemed to lean in collectively, drawn by the quiet gravity of his words.
The screen now displayed a complex branching chart filled with interconnected nodes—decision pathways, psychological stress thresholds, environmental variables, and behavioral response probabilities.
To the untrained eye, it looked chaotic. To Shen Wuyou, it was a map.
"The survivors," he said quietly, his gaze sweeping the room, "are the ones who recognize the system before anyone else does."
A ripple of murmurs spread through the lecture hall. Students exchanged uneasy glances, some leaning forward as if to grasp a thread of understanding that hovered just out of reach.
Shen Wuyou began pacing slowly across the stage, each step deliberate and measured.
"Human behavior becomes highly predictable under stress," he continued, his voice steady, almost detached. "Panic compresses perception. Fear accelerates decision-making but reduces analytical depth. Moral hesitation… creates fatal delays."
A student raised a hand, voice tinged with uncertainty. "So… morality reduces survival chances?"
The question hung in the air like a dropped pebble in still water.
The lecture hall grew quieter, every eye on him, every mind attempting to reconcile instinct with intellect. Even the professors at the back leaned forward, caught between curiosity and disbelief.
Shen Wuyou stopped mid-step.
He fixed his gaze on the student and answered without a trace of hesitation.
"Morality slows decision-making."
A ripple of discomfort ran through the audience. Some students shifted in their seats, uneasy at the bluntness of the statement.
He tapped the remote. Another slide illuminated the screen. Rows of photographs captured fleeting microexpressions; graphs charted physiological stress responses; timelines documented behavioral reactions from controlled crisis simulations. The data was precise, clinical, and impossible to ignore.
"When people are afraid, they make three predictable mistakes." Shen Wuyou said, his voice steady.
He raised one finger. "They assume others will cooperate."
A second finger. "They assume the system is fair."
Then a third. "They assume survival is the objective."
Each point landed in the room like a quiet hammer strike, and for a moment, the lecture hall was silent—every eye fixed on him, every mind processing the unsettling implications of his words.
Several students frowned, exchanging uneasy glances.
Professor Liu Rong, who had been observing quietly at the side of the stage, finally spoke. "You don't believe survival is the objective?"
Shen Wuyou turned toward him, expression calm and unreadable.
"In most structured crises," he said evenly, "survival is a side effect."
The room fell silent once more. Every pair of eyes seemed to tilt toward him, trying to catch even the slightest hint of uncertainty.
Professor Liu Rong studied him, curiosity and skepticism warring in his gaze. "Then what is the objective?"
Shen Wuyou's eyes drifted back to the projection screen, lingering over the branching charts and data points. His voice softened, yet carried a weight that made every word land like a stone in water.
"The objective is discovering the rules before the system eliminates you," he said with finality in his voice.
A long pause stretched across the lecture hall. Somewhere in the back row, a student whispered, almost to themselves, "That's… unsettling."
A few others let out nervous, hollow laughs. The sound only underscored the tension, reminding everyone that they were not merely observing a lecture—they were glimpsing a mind that saw the world in a way few dared to imagine.
Professor Liu Rong rubbed his chin, brow furrowed in thought. "You make it sound like life is some kind of game."
Shen Wuyou offered a faint shrug, almost casual, as if the statement required no defense. "Games are simply systems with defined rules," he said softly.
He turned his gaze back toward the audience, eyes scanning the rows of students. "Life just hides them better." He added, his voice carrying a quiet weight.
The words hung in the air, deceptively simple, yet heavy with implication. A few students exchanged uneasy glances, sensing the depth beneath his calm tone.
When the lecture finally ended, the crowd did not rush for the doors.
Instead, students lingered near the stage, forming a loose circle around Shen Wuyou, their curiosity palpable. Questions tumbled out all at once.
"Wuyou, the decision-tree model you showed—did you build that from real experiments?"
"Your survival probability calculations—can you share the dataset?"
"Do you actually believe people would sacrifice others that easily?"
Shen Wuyou answered each question with the same calm precision that had defined the lecture.
"Yes."
"Possibly."
"Very easily."
Every response landed with clinical clarity, delivered without a trace of emotion, yet each carried an undercurrent that unsettled the students. They nodded, scribbled notes, or stared, realizing that his detachment was not ignorance—it was mastery.
Nearby, two classmates whispered to each other, their voices barely audible over the soft shuffle of students leaving.
"That guy's brain is terrifying."
"Yeah. He studies people like they're animals."
Gradually, the crowd thinned, leaving only a handful of lingering students. Among them was Lin Qian, a member of Shen Wuyou's research group. She crossed her arms, eyes fixed on him with a mixture of curiosity and exasperation.
"You know, sometimes I wonder if you even like people." She said.
Shen Wuyou placed his notes neatly into a folder, his movements calm and deliberate.
"I do."
Lin Qian raised an eyebrow. "You don't act like it."
He paused, considering her words, then replied with quiet honesty, "I like observing them."
The words hung in the air—simple, unembellished, yet revealing more about him than any lecture ever could.
"See? That's exactly what I mean." Lin Qian let out a small, resigned sigh, realizing that with Shen Wuyou, everything, even affection, was filtered through observation.

Three hundred kilometers away, the mood inside the Shanghai Criminal Psychology Bureau was far from academic.
The conference room reeked faintly of stale coffee and overheated printer toner. Crime scene photographs were scattered across the long metal table, each one more gruesome than the last.
Detective Guo Ming slammed a thick case file onto the surface, the thud echoing through the room.
"Three victims in ten days," he said, frustration evident in his voice. "All stabbed. Same pattern."
Across the table, Dr. Liang Zeyan flipped through the photographs without a word. His posture remained relaxed and composed, almost eerily so. Calm, yet deliberate and unsettlingly precise.
Another detective, leaning against the wall, shifted impatiently. "Doctor Liang," he said, voice edged with urgency, "what do you think?"
Liang Zeyan didn't respond immediately.
He studied the photographs carefully, one by one, his gaze steady and methodical.
The first victim: a young man, stabbed in a narrow alleyway.
The second: a middle-aged woman, killed inside her apartment.
The third: a security guard, murdered in a dimly lit parking lot.
At first glance, the crimes seemed unrelated—different victims, different locations, different circumstances.
But Liang Zeyan saw patterns that others couldn't.
He tapped the first photograph lightly. "Impulsive violence."
Then the second. "Controlled repetition."
And finally, the third. "Ritual formation."
Guo Ming frowned, leaning closer to the table. "You're saying the killer is evolving?"
Liang Zeyan closed the file slowly, deliberately. "Yes."
Another detective scoffed, disbelief in his tone. "So what? He's… practicing?"
"In a sense," Liang Zeyan replied evenly, his gaze never leaving the photos spread before him.
A heavy silence settled over the room.
Guo Ming leaned forward, voice low and tense. "When does he stop?"
Liang Zeyan met his eyes with unflinching calm. "He doesn't."
The words hung in the air. One of the detectives rubbed his forehead in frustration. "Fantastic."
Another officer cleared his throat, hesitant. "Can you predict what he does next?"
Liang Zeyan paused, studying the evidence in his mind, weighing the possibilities with clinical precision. Then, finally, he said, voice quiet but firm:
"He wants recognition."
The detectives exchanged uneasy, confused glances.
"This killer," Liang Zeyan continued, voice calm and deliberate, "is constructing a narrative. Each murder builds upon the last, forming a pattern."
Guo Ming's brow furrowed. "You're saying… he wants an audience?"
Liang Zeyan nodded once, without hesitation. "Yes."
"And who's the audience?" another detective asked, unease creeping into his tone.
Liang Zeyan's gaze drifted over the crime scene photographs again, lingering on the subtle consistencies others had missed. Then, quietly, almost to himself, he said:
"Someone capable of understanding the pattern."
The room went silent. The weight of his words pressed down on them, a chilling reminder that the killer's intent was not random—it was deliberate, methodical, and terrifyingly intelligent.

That night, Shen Wuyou returned home.
His residence sat on the western edge of Hangzhou, nestled in a quiet neighborhood lined with old camphor trees and traditional courtyard houses. It was not the kind of place most university students called home.
But Shen Wuyou was not most students.
His parents—both respected scholars—spent most of the year shuttling between international conferences and research institutions. The house remained largely empty, and he preferred it that way. Silence sharpened his senses; observation became easier in the absence of distraction.
As he stepped into the living room, something immediately drew his eye.
A black, elegant envelope trimmed with gold rested on the small wooden table beside the window.
Shen Wuyou halted in his tracks. He had not been expecting any mail.
The envelope looked… expensive. And yet, there was something strangely formal about it, as if it carried a significance beyond its weight or texture.
He stepped closer, eyes narrowing.
At the center of the envelope, an emblem gleamed faintly in the dim light.
An intricate All-Seeing Eye, etched in raised gold foil, stared outward as though it were aware of him.
The eye was framed within a geometric sigil—an upright triangle enclosed by a circular ring, interrupted by tiny, arcane markings. Fine golden lines radiated outward from the hollow pupil, like a miniature tarot spread frozen in metal.
The iris itself was empty.
And yet, if one stared long enough… it seemed to stare back.
Shen Wuyou reached out and picked up the envelope.
The seal across the flap was not wax. Instead, a thin line of molten gold had been poured along the fold and hardened into a flawless strip, embossed with the same all-seeing eye.
He opened it carefully.
Inside lay a black card, edged in gold. Two lines of text shimmered at the top:
"The stars have chosen you as a Cardbearer."
"Will you accept the path written in your fate?"
Beneath the message rested a single tarot card. Shen Wuyou turned it over, eyes narrowing slightly.
The Fool — Reversed
He studied the illustration in silence. A traveler stood at the edge of a cliff—not stepping forward, but tipping backward into the void. The motion was frozen yet unnervingly inevitable.
Shen Wuyou leaned against the table, fingers brushing the edge of the card as if measuring its weight.
"Interesting," he murmured, voice quiet but thoughtful.
—————————————————
At the same moment in Shanghai—
Liang Zeyan returned home from work.
The instant he stepped into his apartment, something caught his attention.
A black envelope lay on his desk.
He approached slowly, each step deliberate. The same All-Seeing Eye stared up at him, intricate and unblinking. For a moment, the symbol stirred something faint in the back of his mind—a fragment of familiarity he couldn't quite place.
He opened the envelope carefully.
Inside, the message was identical:
"The stars have chosen you as a Cardbearer."
"Will you accept the path written in your fate?"
The card beneath it gleamed in white and gold.
He turned it over, pupils narrowing ever so slightly.
The High Priestess — Upright
For a brief moment, a whisper brushed the edges of his mind. Not a sound. Something ancient—yet familiar.
Like a memory waiting to unfold.
And somewhere far beyond the world, something that had slept for centuries slowly stirred, opening its eyes.
