The bear filled the doorframe.

  It had grown. The plush toy from the sofa was gone, replaced by something that barely fit through the bathroom entrance—two meters of matted black fur split by seams that oozed a dark, viscous fluid. Its button eyes were the size of fists now, burning with a red light that cast shadows on the cracked tiles. Its mouth hung open, revealing row upon row of translucent barbed teeth arranged in the concentric spiral of a lamprey’s maw.

  It lunged.

  David didn’t think. His body—repaired badly, held together by adrenaline and the System’s bare minimum life support—threw itself sideways with a desperation that bypassed conscious decision-making entirely. The bear’s jaws snapped shut on the air where his head had been. Its teeth sheared through the rinsing cup he’d dropped, bisecting it cleanly.

  He rolled through the destroyed doorframe and into the hallway. His ribs screamed. His vision strobed. But his legs were still working, and right now, legs were the only variable that mattered.

  He ran for the stairs.

  Not down. Up.

  The second floor. Father’s domain. The one place in this house that every rule warned against, the forbidden zone that even the polluted rules didn’t dare rewrite.

  Rule 7: The master bedroom on the second floor belongs to Father. Entry is forbidden.

  Rule 10: Father hates disobedient children.

  The logic was obvious—so obvious it was elegant. In this dungeon’s hierarchy, the "Father" was the root administrator. The bear—the dead child’s avatar—was a user-level process. It could terrorize other user-level entities all night long, but the moment it entered admin space, it was subject to admin rules.

  And admin rule said: any disobedient child gets erased.

  The strategy was called "privilege escalation through domain transfer"—or, in terms a non-programmer would understand: lure the monster into a bigger monster’s territory and let them fight.

  David took the stairs three at a time. Behind him, the bear crashed into the stairwell, tearing chunks from the wooden banister with each lurch. Its body was too large for the space—it compressed itself, bones cracking and reforming, to squeeze through the narrow passage.

  The master bedroom door was at the end of the upstairs hall. Heavy black oak, older than the rest of the house, with a brass handle that was ice-cold to the touch.

  David threw it open and stepped inside.

  The pressure hit him like walking into deep water. Not physical weight—something older, something that pressed against his consciousness rather than his body. The room was dark, but it was a purposeful dark—the dark of a space that had chosen not to be illuminated.

  The smell: cigar ash and dried blood. A lot of dried blood. The kind of smell that seeped into wood grain over years, over decades.

  In the center of the room, on a massive bed, a shape slept. David couldn’t see its details. He didn’t want to. The shape was human in outline but wrong in proportion—too long, too heavy, displacing the mattress in a way that suggested mass well beyond what bone and muscle could account for.

  On the wall, a single rule. Not written in ink or blood—carved into the plaster itself, each letter gouged deep enough to expose the wooden lathing beneath:

  [Ultimate Domain Rule: Master Bedroom]

  The Only Rule: Do not wake Father. Any living entity producing sound above 20 decibels within this room will be instantly erased.

  Twenty decibels. David’s CS training supplied the reference points automatically: twenty decibels was a whisper. A cat’s footstep. The sound of breathing through your nose in a quiet room.

  The bear appeared in the doorway behind him.

  And stopped.

  For the first time since the game began, David saw the monster hesitate. The bear’s massive body trembled. Its burning eyes, which had tracked David with relentless predatory focus, were now fixed on the shape in the bed. The creature was terrified.

  Stolen story; please report.

  It understood this room. It had lived in this room. It had died in this room.

  The bear began to retreat, its bulk compressing back through the doorframe.

  David couldn’t let it leave.

  One more deduction. He could afford one more. Maybe.

  "Infinite Deduction—activate."

  The pain was blinding. Something in his left eye socket pulsed, and for a moment he couldn’t see out of that eye at all. The world froze.

  [Simulation 1: David shouts to wake Father.]

  Father wakes. Father does not discriminate. Every living entity in the room—David, the bear—is erased simultaneously.

  [Result: Death.]

  [Simulation 2: David physically grapples the bear, holding it in the room.]

  The struggle produces sound far above 20 decibels. Father wakes. See Simulation 1.

  [Result: Death.]

  Two failures. David’s nose was bleeding freely now, and the blood running down his chin was warm and dark. His cognitive capacity was in the red zone—he could feel thoughts fragmenting, losing their edges, like data corrupting in real time.

  But the two failures had given him the constraint: he couldn’t make the sound. He couldn’t touch the bear. He needed the bear to make the sound itself, of its own volition, while David was hidden under the protection of Rule 8.

  He opened his eyes. No more deductions. This had to be done in meatspace, in real time, with no save-scumming.

  His gaze swept the room in the dark. Coat rack by the door. Father’s possessions: a heavy black leather jacket. A pair of work boots. An ashtray full of old butts.

  The jacket.

  David reached out—slowly, silently, his fingers closing around the leather collar with the care of a man defusing a bomb. He lifted it off the hook. No sound. The leather was stiff and heavy.

  The bear was halfway through the doorframe, retreating. In three seconds, it would be in the hallway, out of Father’s domain, beyond admin jurisdiction.

  David threw the jacket.

  It sailed across the room in a flat arc, spreading open like a net, and landed perfectly over the bear’s head—covering its eyes, its mouth, its ears. The bear couldn’t see. The bear couldn’t understand what had happened.

  And a frightened child, blinded and panicked, does only one thing.

  It screams.

  "ROARRRRR———!!!"

  The sound was enormous. 100 decibels, maybe more—a blast of anguished, animalistic fury that rattled the walls and shattered the window. Five times over the threshold. Ten times.

  In the same instant David threw the jacket, he had already dropped to the floor and rolled under the massive bed, pressing his face into the dusty floorboards, both hands clamped over his mouth and nose.

  Rule 8: If you hear heavy footsteps approaching, hide under the bed. Close your eyes. Stop breathing.

  He stopped breathing.

  Above him, the bed groaned.

  "Who... is... disturbing... me."

  The voice was not loud. It was barely above the 20-decibel threshold itself. But it carried a physical force that David felt in his organs—in his liver, his kidneys, the chambers of his heart. It was the voice of something that had absolute authority over this space and was now exercising it.

  A pale hand—massive, the fingers too long, the joints bending at angles that human anatomy didn’t support—reached down from the bed and found the bear.

  "Disobedient... trash..."

  The sound that followed was not a fight. It was an execution. The hand squeezed. The bear, two meters of supernatural horror that had chased David through every room of this house, was compressed like a sponge. Its bones snapped. Its barbed teeth shattered. Its burning red eyes flickered, dimmed, and went dark. The viscous fluid that had been its blood sprayed across the walls in arterial arcs.

  In two seconds, the bear was a puddle of black sludge on the floor. The dead child’s avatar, destroyed by the father who had created it through abuse and violence.

  Under the bed, David held his breath until his vision went completely black. His lungs burned. His broken ribs felt like they were puncturing his diaphragm. The biological imperative to inhale was so overwhelming that his jaw muscles trembled from the effort of keeping his mouth sealed.

  He was going to pass out. He was going to gasp. He was going to die under this bed, inches from survival, because his body couldn’t override its own respiratory reflex—

  DONG. DONG. DONG. DONG. DONG. DONG.

  The grandfather clock in the living room struck six.

  [Ding. Detected: Player has survived until 06:00.]

  [Detected: Player used cross-domain rule conflicts to eliminate Major Entity "Wraith Bear."]

  [1-Star Dungeon "The Midnight Haunted House": Cleared.]

  David gasped. Air flooded his lungs like ice water. He lay under the bed, shaking, bleeding, his cognitive systems so depleted that for a long moment he couldn’t remember his own name.

  Then the room dissolved. The house, the bed, the black sludge that had been the bear, the sleeping shape that had been Father—all of it shattered like glass and fell away into the void, taking the mold-and-blood smell with it.

  He was falling again. But this time, when he landed, there was light.
