At 11:59 PM the next day, since the people around the world started receiving strange envelopes, the world appeared perfectly ordinary.
Hangzhou's city lights shimmered against the darkened river, neon reflections rippling like liquid glass on the water's surface. Late-night traffic hummed along the arteries of the metropolis, the headlights and taillights tracing luminous streaks through empty streets.
Apartment windows glowed faintly, each a silent theater of private lives—students hunched over their desks beneath harsh fluorescent lamps, writers peering at flickering monitors, and night-shift workers nursing cups of coffee and exhaustion in equal measure.
Office towers loomed above, their dark glass facades reflecting the restless glow of the river, monumental mirrors that seemed to absorb the city's energy rather than illuminate it.
Across the globe, moments like this played out in countless variations.
In Berlin, a nurse monitored a patient's vitals, fingers brushing over a heart monitor with quiet, practiced precision.
In Seoul, a taxi driver waited, half-asleep, for his next fare, leaning against the worn leather seat with a resignation that only late-night labor could cultivate.
In Singapore, a university student scrolled aimlessly through his phone, the soft blue light painting his face with ephemeral shadows.
Outside the Louvre in Paris, a night guard traced the empty steps with bored vigilance, the distant hum of the city echoing faintly against the stone.
And somewhere in each of these places, the first black envelopes, sealed, unmarked, and untraceable, had been opened.
It was the instant before everything changed.
—————————————————
Shen Wuyou sat at his desk, the rest of his house swallowed in silence. A single lamp cast a cone of light over the polished wood, illuminating a black envelope and the card it had contained.
The Fool—reversed.
He had spent the past hour examining it, the same patient, meticulous attention one might devote to unraveling a complex theorem or parsing a coded manuscript. Something was unsettling about the card. Unlike the familiar imagery of traditional tarot decks, the illustration seemed subtly alive. The cloaked traveler at the cliff's edge shimmered in delicate gold lines. Every time Shen Wuyou's gaze shifted, the figure seemed to tremble, to tilt, almost imperceptibly, but enough to set the mind on edge.
He rested his chin lightly on his fingers. "A psychological trigger," he murmured. His voice was more a note to himself than to anyone else, a soft acknowledgment of the unnatural effect it had on perception.
His notebook lay open beside him, pages filled with orderly observations:
Black envelope.
Gold seal.
Unknown delivery method.
Untraceable materials.
Below those notes, a single sentence had been scrawled in ink that still smelled faintly metallic:
If this is a game, the first rule is already clear.
He tapped the card lightly with his pen, the hollow click echoing faintly against the walls. "Someone wants attention," he whispered.
The house was empty except for the faint hum of electronics. His parents were abroad, attending an academic conference, leaving the sprawling residence eerily quiet. A clock ticked softly, each second punctuating the calm before an invisible storm.
11:59:42 PM.
Shen Wuyou leaned back, preparing to jot down another observation, when the light in the room shifted. It did not extinguish; it did not flicker like a failing bulb. It bent inward, folding around him like a living presence. The air thickened, weighty, almost tactile, pressing against the edges of thought.
Then, without warning, a voice spoke.
Not aloud. Not through speakers. It seemed to appear inside his mind with absolute clarity, dispassionate and emotionless:
[System Announcement]
[The Covenant has been activated.]
[All Cardbearers will now enter the trial space.]
[First Instance preparing…]
[Instance Difficulty: Minor Arcana — Entry Level]
[Player Count: 1,200]
[Survival Rate Prediction: 62%]
Shen Wuyou froze, pen suspended midair. His lips curved slightly upward, a smile that was more curiosity than amusement. "…Interesting."
And then the world vanished.
—————————————————
At the same moment, Liang Zeyan's office hummed with quiet chaos.
The investigation department of the Shanghai Criminal Psychology Bureau rarely rested, and even late at night, the desks bore the scars of endless work—stacks of reports, scattered coffee cups, half-used pens, and the faint aroma of fatigue.
Liang Zeyan, tall and broad-shouldered, projected authority even in repose. Officers instinctively straightened when he entered the room, a reflex born of his calm but unyielding presence.
A junior detective dropped a stack of files onto his desk. "Doctor Liang, the forensic report from the Lin'an case came in."
Liang Zeyan's dark eyes lifted from his work. "Cause of death?"
"Poison," the detective replied, hesitating. "But… the strange part is that the victim drank it voluntarily."
Liang Zeyan's gaze swept over the report with the precision of a surgeon inspecting a wound. "Not voluntary," he said after a moment.
The detective frowned. "Then what—?"
Liang Zeyan pointed to a note: dilated pupils. Elevated adrenaline levels. He tapped the paper. "Fear."
Silence stretched across the room.
"Psychological coercion," muttered another officer.
"Most murders aren't physical battles. They're negotiations. Every movement, every word, every glance is part of a conversation. Sometimes you win by persuasion. Sometimes by terror. And sometimes, by making the choice seem inevitable." Liang Zeyan said softly, closing the file.
He rose. "Interview the victim's family again tomorrow. Focus on financial pressures, blackmail, and coercion. Search for fractures in the mind, not bruises on the body."
As the words left his mouth, the lights flickered. Every officer's head jerked upward. Half a second later, the same voice that had spoken to Shen Wuyou filled the office, crystal-clear, inescapable:
[System Announcement]
[The Covenant has been activated.]
[All Cardbearers will now enter the trial space.]
[First Instance preparing…]
[Instance Difficulty: Minor Arcana — Entry Level]
[Player Count: 1,200]
[Survival Rate Prediction: 62%]
"What—?" a detective stammered, coffee spilling across the desk.
And the world dissolved around them.
—————————————————
Shen Wuyou's eyes snapped open to an entirely different reality.
He was no longer in his home, no longer surrounded by the quiet comfort of familiarity. Instead, he stood within a cavernous cathedral, its walls of cold stone stretching into darkness.
The floor beneath his feet was rough-hewn granite, slick with an unseen moisture. Towering walls of the same dark stone soared upward, disappearing into a gloom so profound it swallowed the distant ceiling. Pillars, impossibly thick, rose like petrified trees, their surfaces carved with intricate, unsettling patterns that seemed to writhe in the perpetual twilight. No windows broke the oppressive expanse. No torches flickered. Yet, a faint, ethereal glow emanated from somewhere above, casting long, distorted shadows that stretched and crawled across the floor.
A low, guttural roar ripped through the sudden silence. Panic, raw and visceral, erupted.
Nearby, a woman screamed, a high-pitched, desperate sound that ended abruptly in a sickening wet thud. Others cried out, their voices choked with terror, a cacophony of fear echoing in the vast, echoing space.
Shen Wuyou's gaze swept across the developing chaos, his eyes reflective rather than expressive. Thousands of people, disoriented and terrified, materialized from nothingness. They stumbled, collided, their faces contorted masks of disbelief and dawning horror.
A man in a business suit clawed at the air, his eyes wide, before he dissolved into a spray of glittering black dust. His briefcase clattered to the stone floor, silent.
"What… what is this?" A voice, ragged with terror, sliced through the growing din.
Shen Wuyou watched the business-suited man's dust swirl, then settle, a faint shimmer on the cold stone. A variable was introduced. A system was initiated. His mind, unburdened by fear, began its rapid assessment.
A burly figure in a police uniform, his face already streaked with sweat, shoved past a terrified student.
"Everyone! Stay calm! What's going on?" Detective Guo Ming, from the Shanghai Criminal Psychology Bureau, his voice thick with a desperate authority, tried to assert control. He looked around, his eyes darting frantically, searching for an anchor in the maelstrom.
Not far from Shen Wuyou, Liang Zeyan stood perfectly still, a calm counterpoint to the surrounding pandemonium.
His dark coat seemed to absorb the faint light, his presence a quiet, unyielding anchor in the swirling fear. He did not react to the screams, nor to the man dissolving into dust. His deep brown eyes, usually so composed, now held a glint of something ancient, something that recognized the strange geometry of this new reality. His gaze was not on the frantic crowd, but on the shifting patterns of the shadows, the subtle, almost imperceptible misalignment that hinted at an impossible architecture.
A woman, her neatly tied hair now disheveled, stumbled near Liang Zeyan.
"Doctor Liang? Where are we? What happened?" Liang Fang, a cautious, analytical researcher from his own department, clutched her arm, her voice tight with suppressed hysteria.
Liang Zeyan's attention remained fixed on the cathedral's impossible geometry. The pillars rose too straight, the arches curved too perfectly, and the spaces between them seemed deeper than they should have been. Slowly, he lifted a hand—a silent signal for Liang Fang to wait. His lips moved only slightly as he spoke, his voice barely louder than a breath.
"The shadows… look at them."
Liang Fang followed his gaze. The faint light spilling down from the high, unseen ceiling stretched the pillars' silhouettes across the stone floor. At first, they looked ordinary—long, thin shapes cast by the candlelight and distant glow above.
Then they moved.
Not much. Just enough to feel wrong. The shadows wavered like reflections in disturbed water. One pillar's silhouette seemed to stretch too far, another bent at an angle that didn't match the stone column beside it.
And for the briefest moment, Liang Fang swore she saw one of them detach completely—peeling away from the pillar that should have anchored it, drifting a few inches across the floor like living ink before snapping back into place.
Her breath caught in her throat.
Was it just a trick of the light?
"They don't align with their objects," Liang Zeyan observed, his voice a low murmur, almost a private thought. "The light source… it's not singular. Or it's not physical."
Shen Wuyou, drawn by the quiet, analytical tone, turned his head slightly. He noted Liang Zeyan's posture, the subtle shift in his gaze from the panicked crowd to the environmental anomaly. An interesting observation. Most would still be processing the sudden displacement. This man was already dissecting the system.
A young woman, Chen Rui, her face wet with tears, collapsed to her knees, sobbing uncontrollably.
"I just want to go home! This isn't real!" Her cries were sharp, piercing the din.
Guo Ming, his face grim, rushed towards her. "Hey! Pull yourself together! We need to stick together!" He tried to hoist her up, but she merely wept harder.
A quiet man with intelligent eyes, Zhao Wei, a paramedic, knelt beside Chen Rui.
"Her breathing's hyperventilating. We need to get her calm." He spoke with a quiet authority, pulling a small, battered first-aid kit from his bag, a practical response in an impossible situation.
Shen Wuyou watched them, a faint, almost imperceptible smile playing on his lips. Predictable. The strong attempt to control; the weak succumb; the practical seek solutions. All within established behavioral parameters for crisis.
He shifted his gaze back to the cathedral walls. Faint, almost invisible, sword silhouettes glowed with a cool, internal light. Ten of them, etched into the stone, barely visible beneath the grime and shadow. They were not carvings. They were impressions, like residual energy. It's the card, Ten of Swords. He remembered its name from the envelope. He began to trace their faint outlines with his eyes, counting them.
Liang Zeyan's voice cut through the air, quiet but firm. "Don't touch them."
Guo Ming, who had been about to reach for one of the glowing sword impressions, froze. "What? Why not?"
Liang Zeyan's eyes, now colder, fixed on the detective.
"The shadows distort. The light source is an illusion. Any physical interaction with an environmental anomaly here… it's a risk." He did not explain further; his words were concise and definitive.
Shen Wuyou observed Liang Zeyan. The man did not just see patterns; he predicted consequences—a valuable asset.
"Risk of what?" Chen Rui wailed, her voice cracking.
Another scream. Another shimmer of black dust. This time, a young man, who had been frantically trying to pry open a heavy wooden door at the far end of the hall, simply imploded. The door remained shut, unyielding.
The screams intensified. The panic became a tangible thing, a wave of desperate energy washing over the thousands.
"We need to find an exit!" someone yelled.
"There are no exits!" another shrieked.
Guo Ming's face was pale, but he clenched his jaw. "Everyone! Listen to me! We need to form groups! Stick together!"
He pointed towards a cluster of people, trying to herd them. His voice was loud, but it was being swallowed by the general hysteria.
Liang Fang, now beside Liang Zeyan, spoke, her voice still trembling but regaining a sliver of its usual analytical edge. "Doctor Liang, your observation about the shadows… it implies a simulated environment, or a projection. Not a physical space."
Liang Zeyan nodded, his gaze scanning the vast cathedral, taking in the details that others missed in their panic.
"Or a reality built on different rules. The fundamental laws of physics are… negotiable here." His eyes narrowed, a faint ripple of something ancient stirring beneath their calm surface.
Yanluo, his other personality, his shadow, the silent protector, sharpened his focus. This environment was not just a puzzle. It was a threat.
Shen Wuyou stepped closer, his voice a low, almost melodic hum that cut through the chaos without effort.
"Negotiable rules suggest a system. A system suggests an objective. And objectives often have… a price." He did not address Liang Zeyan directly, but spoke to the air, to the architecture itself.
Liang Zeyan turned his head, his deep blue eyes meeting Shen Wuyou's dark brown ones. A flicker of recognition, a silent acknowledgement of shared intellect, passed between them.
"A price already being paid," Liang Zeyan replied, his gaze drifting to the lingering black dust. "And rapidly increasing."
Guo Ming, overhearing, scoffed. "A price? What are you two talking about? We're trapped in some nightmare, and you're talking about prices and systems?" He gestured wildly at the dissolving figures. "People are dying!"
"Precisely," Shen Wuyou said, his tone utterly devoid of emotion. "Their deaths are data points. What triggered them?"
Guo Ming stared at him, aghast. "Triggered them? They're just… dying! Randomly!"
Liang Zeyan interjected, his voice calm, cutting through Guo Ming's frustration. "Nothing in a structured system is random. The man who dissolved first… he screamed in panic."
He paused, his eyes sweeping the crowd. "The second tried to force an exit."
Shen Wuyou picked up the thread, his voice a quiet counterpoint. "The woman who screamed was alone, isolated. The man with the door was attempting to break the system's boundaries."
His gaze flickered to the faint sword silhouettes on the wall. "Each death is a misstep. A violation of an unseen rule."
Liang Fang, her eyes wide, gasped. "So there are rules… but we don't know them?"
"And misinterpreting them leads to… dissolution," Liang Zeyan concluded, his voice heavy with implications. "A complete erasure."
Zhao Wei, the paramedic, stood up, having managed to calm Chen Rui slightly, though she still trembled.
"So what do we do? Just… stand here and wait to die?" His voice was practical, but laced with a dawning dread.
Shen Wuyou's eyes scanned the vast space again, taking in the sheer number of people, the rising tide of fear.
"Observe. Deduce. Survive." His words were simple, yet carried an absolute conviction.
"Observe what?" Guo Ming demanded, his hands clenching into fists. "The shadows? The dead bodies?"
"The patterns," Shen Wuyou clarified, his gaze briefly resting on Guo Ming. "The fear. The instinct. The choices people make under duress. Those are the variables."
Liang Zeyan nodded slowly. "And the environment. The cathedral itself is a clue. Its architecture, its symbols… they are not arbitrary."
He pointed towards a massive archway that led deeper into the cathedral, its darkness more profound than the main hall. "That path… It's inviting, yet foreboding. A classic psychological trigger."
Chen Rui, her voice still shaky, finally spoke. "I don't want to go in there. It's too dark."
Guo Ming, who had been boasting earlier, now faltered. The archway truly did resemble a gaping jaw. "Maybe we should stay in the main hall for the moment," he said. "Regroup first."
Liang Fang, ever analytical, considered. "If this is a system, then the initial area might have an introductory phase. Moving deeper without understanding the rules would be… reckless."
Shen Wuyou's eyes, however, were fixed on the glowing sword silhouettes. He noticed a subtle difference between them. Some were clear and sharp. Others seemed to shimmer, their edges blurring.
"Not all risks are equal," he murmured, almost to himself. "Some risks are tests."
His gaze returned to Liang Zeyan. "What do you see in the patterns?"
Liang Zeyan met his gaze, a silent dialogue passing between them. "Fear amplifies distortion. The shadows… they feed on panic. The dissolution is not random. It's a consequence of emotional and behavioral missteps."
His voice was low, for Shen Wuyou's ears alone. "The system is designed to exploit fundamental human weaknesses."
"And what about strengths?" Shen Wuyou countered, a glint of challenge in his eyes.
Liang Zeyan offered a faint, almost imperceptible smile. "That's what we're here to discover."
He turned to the small group that had gathered around them – Guo Ming, Liang Fang, Zhao Wei, and the still-shaking Chen Rui.
"We need to move. Not deeper into the unknown, but to a position where we can observe without being directly in the path of the current chaos." He pointed to a slightly raised platform, almost an altar, at the side of the main hall, shrouded by a cluster of massive pillars.
"There. It offers a vantage point and some cover."
Guo Ming, though still wary, saw the logic. "Alright. Everyone, move towards the altar! Slowly!"
He began to guide the small group, his earlier panic giving way to a nascent leadership.
As they moved, the sheer scale of the cathedral became more apparent. The air grew colder, the faint light seemed to dim, and the screams of the thousands of trapped players faded into a distant, horrifying chorus. The altar, when they reached it, was cold and smooth, carved from the same dark stone.
Liang Fang shivered, rubbing her arms. "It's like… a tomb."
Zhao Wei, ever practical, scanned their surroundings. "No obvious traps here. But the air… it feels heavy."
Shen Wuyou, ignoring their comments, began to examine the altar's surface. Intricate carvings covered it, depicting figures in various states of distress, surrounded by swirling patterns that resembled stylized swords. His long fingers traced the cold stone, his movements precise and deliberate.
"The iconography is consistent. The fallen blades… they are not just decorative."
"What do they mean?" Chen Rui whispered, fear still clinging to her voice.
Liang Zeyan's eyes were drawn to a specific carving on the altar. A figure, bound and blindfolded, stood before ten upright swords. Beneath it, a single phrase was etched in an archaic script. He recognized it, a shadow memory stirring in his mind.
Yanluo's presence sharpened, a cold certainty. "It's a warning. A prophecy."
Guo Ming leaned closer. "Can you read it?"
Liang Zeyan's gaze was distant, as if reading something far beyond the stone. "It speaks of betrayal. Of shattered trust. Of the mind becoming its own prison."
His voice was low, resonant, as if he were channeling an ancient voice. "The Ten of Swords… It's not just physical death. It's the death of hope, of belief."
Shen Wuyou looked up from his own observations, his eyes meeting Liang Zeyan's.
"Psychological triggers. The system exploits internal weaknesses." He paused, then pointed to a subtle detail in the carving.
"Look here. The swords… they are not solid. They are woven from doubt."
Liang Fang gasped, a sudden realization dawning on her. "So the deaths… they're not just from touching traps. They're from giving in to fear, to despair?"
"Or to misplacing trust," Liang Zeyan added, his eyes sweeping over their small group, a silent assessment. "The system will test our cohesion. Our loyalty."
Guo Ming shifted uncomfortably. "Are you saying… we can't trust each other?"
"We can trust the patterns," Shen Wuyou corrected, his voice flat. "And we can trust the rules, once we discern them. Trust in individuals… is a variable."
Chen Rui began to cry again, softly. "This is too much. I can't… I can't do this."
Zhao Wei placed a comforting hand on her shoulder. "We have to, Chen Rui. We have no other choice."
Liang Zeyan turned his attention back to the broader cathedral. The faint sword silhouettes on the walls now pulsed with a barely perceptible light, almost like a slow, deliberate heartbeat.
"The system is activating its next phase. These… are not just images. They are active elements."
Shen Wuyou followed his gaze, his eyes narrowing. "Each corresponds to a psychological trigger. A behavioral test."
His voice was quiet, contemplative. "Ten swords. Ten aspects of mental collapse."
He walked towards one of the glowing sword silhouettes, his movements unhurried, almost languid.
Guo Ming tensed, ready to stop him.
"Don't touch it," Liang Zeyan warned, his voice sharper this time, a sudden urgency in its tone. Yanluo's instinct, raw and protective, flared.
Shen Wuyou paused, his fingertips a hair's breadth from the glowing outline. He did not look at Liang Zeyan. Instead, his dark eyes focused on the patterns within the faint light. "It's not a physical trap."
"It's a conceptual one," Liang Zeyan finished, his voice tight. "A thought trap. A trigger for mental dissolution."
Shen Wuyou slowly pulled his hand back, a faint, almost imperceptible smile touching his lips.
"Interesting." He turned to Liang Zeyan, a question in his eyes. "How do you know?"
Liang Zeyan's gaze was intense, distant. "The feeling. The resonance."
He did not elaborate, but the implication hung heavy in the air: he knew. Not through deduction, but through something deeper, something ancient.
Guo Ming, frustrated by their cryptic exchange, threw his hands up. "What feeling? What resonance? Can someone please speak in human language? What are we supposed to do?"
Liang Fang stepped forward, her brow furrowed in thought. "If the swords represent psychological triggers, then the objective isn't to avoid them physically, but to… mentally overcome them? Or avoid the conditions that activate them?"
"Exactly," Shen Wuyou confirmed, his gaze returning to the glowing swords. "Each sword represents a failure condition. Doubt, fear, betrayal, despair…"
He ticked them off, his voice calm, analytical. "The challenge is to identify which sword corresponds to which mental state, and how to navigate it."
Zhao Wei, the paramedic, though clearly out of his depth, tried to apply logic. "So, if someone starts to panic, they're activating a 'fear' sword? And that's what causes them to dissolve?"
"A possibility," Liang Zeyan conceded. "The system uses archetypal fears. The Ten of Swords often represents utter ruin, a rock bottom. But in reverse, it can signify escape, or even a new beginning."
He glanced at Shen Wuyou, a silent acknowledgement of their respective cards. The Fool (Reversed), a journey into the unknown, a leap of faith, or recklessness.
The High Priestess (Upright), hidden knowledge, intuition, veiled truths. Their cards, their roles, were already shaping their perception of this new reality.
The cathedral floor rumbled. A low hum vibrated through the stone, growing steadily louder. The faint light from above intensified, then flickered, casting even longer, more distorted shadows.
"What's happening now?" Chen Rui whimpered, shrinking behind Zhao Wei.
"The instance is stabilizing," Shen Wuyou observed, his voice almost eager. "The initial chaos phase is ending. The rules are becoming more defined."
Suddenly, a massive slab of stone, carved with the same sword iconography as the altar, slid down from the ceiling, blocking the main entrance through which they had originally appeared. With a deafening boom, it sealed them in.
The thousands of players who had been frantically trying to find an exit in that direction now found themselves trapped. A new wave of panic, sharper and more desperate than before, erupted.
"We're sealed in!" Guo Ming roared, slamming his fist against a pillar. "There's no way out!"
Liang Zeyan's eyes remained calm, but a subtle tension entered his posture. Yanluo surged, a cold, calculating presence, assessing the new parameters of confinement.
"The system has closed off the initial area. It's forcing us into the next phase."
Shen Wuyou, however, was smiling faintly. A private, knowing curve of his lips.
"The game has begun." He looked at Liang Zeyan, his gaze sharp, assessing. "Are you ready to play?"
Liang Zeyan met his gaze, his own eyes holding a depth that seemed to absorb the dim light.
"I've been ready my whole life." His voice was low, a quiet promise, a challenge accepted.
The two men, one walking towards the abyss, the other standing at its edge, found a strange, dangerous symmetry in the heart of the Cathedral of Fallen Blades. The system had chosen its players, and the game had just found its strategists.
