Chapter 3 — Radius
Day Four.
Lufias did not fight.
He stayed by the window for nearly an hour. He wasn't just staring; he was recording.
A Walker crossed the asphalt at 7:12 a.m. Another followed at 7:19. Both reacted instantly to a metallic crash echoing from somewhere down the block, pivoting toward the sound with jerky, mechanical intent.
Variable confirmed: Sound is the primary trigger.
By 7:40, the street was a graveyard of stagnant shadows again. The movement came in waves—not constant, not random.
Predictable.
He committed the patterns to memory. No notebook. No digital device. Just raw data stored behind steady, unblinking eyes.
He did not open the apartment door that morning. Instead, he conducted a forensic search of his living space. He checked behind the refrigerator, under the rusted pipes of the sink, and inside the depths of the toilet tank.
He salvaged a meager haul:
* Two strips of generic painkillers.
* A half-used bottle of antiseptic.
* One roll of gauze bandage.
* A bottle of expired cough syrup.
He arranged them on the kitchen table with surgical neatness.
Medical supply: Critically low. Risk of infection: Extreme.
He returned to the window.
Across the street sat a convenience store, its glass frontage shattered into a jagged grin. To the left, two blocks away, a faded green cross marked a pharmacy.
That cross mattered more than anything else.
"Water first," he whispered to the empty room. "Medicine second. Food third."
It wasn't a rule. It was a priority chain.
Day Five.
He cracked the apartment door open. He listened to the silence until it felt heavy. The hallway smelled of damp wood and the sour, cloying scent of something that had died weeks ago.
He stepped out. He didn't rush to the stairs. He cleared each floor first.
One step. Pause. Listen.
When he reached the ground floor, he merged with the shadows of the stairwell. The main entrance hung on a single hinge, allowing a spear of dust-filled light to pierce the gloom.
Outside, a Walker wandered near a skeletal car. Another leaned against a lamppost, its body sagging as if held up only by habit.
He did not engage. He retreated.
Mapping came first.
Back inside, he tore a panel from a cereal box and drew a crude layout.
Apartment. Street. Store. Pharmacy. Blind corners.
He marked the "Kill Zones" and "Dead Zones."
The world felt less chaotic when it was reduced to a blueprint.
Reality: 2066
During his lunch break, the "Model Student" sat quietly in the library. His screen showed harmless tabs, but his private search history told a different story:
"Purifying stagnant water without electricity."
"Boiling point of contaminated fluids."
"Sepsis timeline in untreated lacerations."
If the virus was waterborne, the city's tap supply was a ticking time bomb.
That evening, he boiled a pot of water on his sleek, induction stove. He watched the steam rise, studying the condensation huddling under the lid. He timed it. He observed the sediment.
He wasn't just cooking; he was rehearsing for a future that hadn't happened yet.
Day Six.
He chose the "Low Movement Window"—pre-dawn.
He stepped outside. This wasn't a raid; it was a stress test of the environment. The air was pungent today, a mix of rotting meat and wet asphalt.
He crossed the street, his footsteps light and rhythmic. The Walker by the lamppost didn't flinch.
Distance threshold: 10 meters. Confirmed.
He reached the convenience store. The interior was a tomb of shadows. He picked up a stone and tossed it toward the back of the shop.
Clack.
The sound echoed off the linoleum. He waited, axe raised.
No response.
He stepped inside. The stench hit him like a physical blow—sour decay and ancient blood. He breathed shallowly through his mouth.
The shelves were picked bone-dry. But near the loading dock at the back, he found them: sealed water bottles, stacked low.
He fought the urge to grab them all. Greed was a variable that led to fatigue. Fatigue led to noise.
He took one six-pack. Heavy, but manageable.
On his way out, the Walker by the lamppost twitched. Its head tilted, sensing a shift in the air.
Lufias didn't run. Running created a sound signature that screamed "Prey."
He walked steadily. He crossed the asphalt. He entered the building.
Only when the deadbolt clicked shut did his shoulders drop.
He placed the water on the table and stared at it for a long time.
This was different from before. He wasn't just hiding. He wasn't just reacting.
He was operating.
Day Nine.
He watched from the window. The Walker near the lamppost had finally collapsed. It twitched once, then went still.
He watched it for ten minutes. Nothing.
Natural degradation. Decay.
They weren't infinite. They were biological machines, and machines without fuel eventually seized up.
Time was an ally.
He didn't smile, but the tension in his chest loosened. He wasn't fighting an endless tide; he was fighting a fire that would eventually burn itself out.
Patience would win this war.
He shifted his gaze to the green pharmacy sign. Two blocks away. A blind corner near an alley. At least three potential noise triggers.
He calculated the risk.
Not today. Soon.
He would need the antibiotics. The heavy-duty painkillers. The sterile bandages.
Because eventually, the "Calculator" would make a mistake. And when that happened, preparation would be the only thing standing between recovery—and a slow, preventable death.
The radius had grown. Small, but measurable.
And this time, he was willing to let it grow one calculated inch at a time.
