WELCOME TO REALITY V2.0

Zhang Wei sat with his back against apartment 3C's door, legal pad on his knee, pen poised over a half-filled page. Li Hua sat across the corridor, the wrapped kitchen knife resting across her thighs. Twenty minutes since they'd returned from the sixth floor. Twenty minutes of listening to the building settle — concrete contracting, water pipes knocking, the faint wet breathing from the stairwell that neither of them mentioned.

"Three C is still barricaded," Li Hua said. "I knocked. No answer, but I heard someone breathing on the other side."

"Leave them. If they want help, they'll open."

"Cold."

"Efficient."

Then every screen in the building turned blue.

His phone. Her phone. The emergency lighting panels in the ceiling. The cracked television visible through apartment 3D's window. Every surface that could render text displayed the same frame simultaneously — a blue notification panel, silver border, centered white text. The same design language as the patch notes. Same developer's hand.

SYSTEM BROADCAST — GLOBAL

Welcome to Reality v2.0

Current Global Population: 7,847,263,102

Survive.

Fifteen seconds. Then a second notification replaced it:

SYSTEM BROADCAST — GLOBAL

First Patch Deployment: T-30 days

Prepare accordingly.

Both vanished. Screens went dark, dead, or returned to static. The emergency light resumed its hum.

Li Hua stared at her phone. "Seven point eight billion."

"Down from approximately eight point zero one billion." Zhang Wei was already writing. "One hundred sixty-three million dead in under twelve hours."

Li Hua pressed her palm flat against the wall. He watched her process it — not the number, but what the number contained. One hundred sixty-three million people. Sleeping, driving, eating, mid-surgery. People who never saw a stat screen.

"ER night shifts," she said. "My old department ran twenty staff on twelve-hour rotations. If the monsters hit during a trauma surge—"

"Don't calculate that."

"Don't?" Her voice sharpened. "That's exactly what you're doing. You're running numbers on a genocide."

He was. But his angle was different.

"Two percent," he said. "Twelve hours, zero warning, monsters spawning directly on population centers. Two percent kill rate on a completely unprepared species." He circled the number on his pad. "In game design, the opening area is tuned to a specific attrition rate. Too easy, players get bored. Too hard, they quit. You calibrate for enough death to create urgency without total collapse. Two percent does that."

"You're saying this was calculated."

"I'm saying the System calibrated initial spawn difficulty to produce approximately two percent casualties in the first cycle." He drew a line on the pad. "At that rate, another two percent falls in the next twelve hours. Three hundred twenty million by tomorrow. A billion by day five. The entire human population within a month — unless the difficulty curve changes."

"The patch cycle," Li Hua said.

"Thirty-day intervals. The System kills a percentage per cycle, then patches adjust the parameters. Harder spawns, new mechanics, environmental hazards. This isn't a natural disaster. It's a difficulty tuning algorithm wearing the world like a costume."

She was quiet. Not because she had nothing to say. Because the silence was the only response that wouldn't come out broken.

"The patch notes said Alpha Phase — Balance Tuning Active," Zhang Wei continued. "If the System tracks global survival rates, it will adjust upward. Month two will be harder than month one. Month three harder than that."

"So we have thirty days before the rules change."

"At minimum."

She stood. "Then we need supplies. Real supplies. Food, water, medication, weapons that aren't kitchen knives." She pulled the fire extinguisher from under the stairwell door. "Hardware store across the street — crowbars, axes, rope. If it hasn't been looted already."

"I want to map more of the building first. Every entity, every spawn point—"

"Zhang Wei." She looked down at him. "Data doesn't stop bleeding. Data doesn't close a wound or purify water. At some point you have to stop reading and start doing."

He wanted to argue. His brain was already drafting a mental checklist — spawn density per block, entity type distribution, loot table frequencies. Build the dataset, find the patterns, predict the next cycle. It was the only way he knew how to survive.

But Li Hua was already pulling the stairwell door open. She moved with the decisiveness of someone accustomed to incomplete information — assess, act, reassess. ER triage logic. No luxury of perfect data when someone was dying in front of you.

"Fine. Stairwell A. B stairwell still has the Shade Stalker on Five."

"Noted."

They descended. One flight. Two. On the third-floor landing, Li Hua paused, head tilted.

"Second floor," she said. "Metal on concrete. Something deliberate."

Code Sight triggered:

[ENV_SCAN] Corridor 2F — Building 7 Active entities: 2 Entity 1: Grey Crawler (Level 1) — Status: Deceased Entity 2: Human Player — Level 3

Level 3. Zhang Wei eased open the stairwell door and looked through.

Two Grey Crawler corpses lay in pieces on the corridor tiles, green-black ichor sprayed across the baseboards. A man stood over them — late twenties, broad-shouldered, wearing a faded construction company jacket. He held a fire axe in both hands, driving it into the nearest corpse in efficient, repeating strokes. The creature was already dead. He was dismembering it anyway.

Name tag on the jacket read FANG LEI.

ENTITY: Fang Lei — Human Player Level: 3 STR: 16 | DEX: 12 | CON: 14 HP: 91/100 SP: 45 [SYSTEM_TAG] Kill Count: 9 [SYSTEM_TAG] Aggression Index: High

Nine kills. Twelve hours into the apocalypse, and this man had hunted nine monsters through the building. His STR was already 16 — higher than anyone Zhang Wei had scanned. He had been feeding the level-up system with raw violence.

Fang Lei looked up. Saw Zhang Wei in the doorway. His eyes were bright — not panicked, not traumatized. Hungry.

"You the guy from upstairs?" He rested the axe on his shoulder. "Heard you and the nurse moving around. Opening doors. Walking corridors." He gestured at the corpses. "I've been working down from seven. Clearing every floor."

"Clearing?"

"Killing. Every crawler, every spawn, every drop." He stepped over a body. "You know you level from this, right? Each kill is XP. I'm already three. There are skill trees. Classes locked behind level gates. This is a game, man. An actual game, running on top of reality."

He said "game" the way a drowning person says "rope."

"Eleven kills," Zhang Wei said, reading the stat.

"Twelve, counting the stairwell pair. They got a lady on six before I reached her." No change in his voice. Flat. Already filed. "So I killed them both and kept moving." He looked at Zhang Wei. "Patch notes said thirty days until the first patch. You think the play is hiding and counting numbers?"

"The more monsters you kill in a concentrated area, the more the spawn rate adjusts upward." Zhang Wei held his gaze. "You're pulling density into the building. Every floor you clear, the System replaces with harder spawns."

Fang Lei shrugged. "Good. Harder spawns mean more XP."

"That's not survival. That's an arms race you'll lose."

"That's exactly survival. Level fast. Get skills. Get a class. Be ready when the real threats arrive." He turned to Li Hua. "Nurse, right? 5B?"

"5B," she said.

"Come with me. I clear, you patch me up. Better party composition than whatever this is." He jerked his chin at Zhang Wei. "What's he got? A notebook?"

"We're not a party," Li Hua said. "We're neighbors."

Fang Lei smiled. Not unkind. "For now."

He swung the axe once more into the corridor wall — testing the edge, nothing else. Drywall puffed white. He nodded and walked deeper into the second floor, humming something tuneless.

Li Hua watched him disappear around the corner. "He's going to get someone killed."

"He's going to get himself killed." Zhang Wei pulled the stairwell door shut. "The question is who he takes with him."

They crossed the street in seven minutes. Code Sight swept the route — one dormant Shade Stalker in an alley, one active Grey Crawler two blocks east, both avoidable. The hardware store was half-looted. Axes gone, most bladed tools taken. Crowbars remained, and bolt cutters, and four lengths of rebar someone had missed.

Li Hua packed a backpack. Zhang Wei stood watch at the shattered front window, scanning the street. Overcast sky. Abandoned cars. A distant crash — three blocks east, something heavy going through a wall. Fang Lei's kill zone expanding.

Then Code Sight showed him something that didn't belong.

Not a system notification. Not a debug log. Not an environmental scan. Text that materialized only when he focused on his character sheet, only in the far periphery of his vision, like a message slipped between layers of code where the normal System never looked:

[HIDDEN] // Source: [NON_STANDARD]

Quest Triggered: ??? Location: Building 7 — Sublevel 1 Condition: Code Sight active — Observer classified Reward: [REDACTED]

// Note: This quest does not exist in standard System architecture. // Classification: External injection. Unverified origin.

He read it twice.

Wrong formatting. Double slashes instead of brackets. Source tag: NON_STANDARD. The annotation at the bottom: External injection. Unverified origin. This wasn't from the Test Framework. Wasn't from the automated deployment system. Wasn't from whatever authored the patch notes.

Something inside the System had written a quest that the System itself did not recognize.

He checked the Watchdog:

System_Watchdog: Active — Sector 7-Alpha Status: OBSERVE Directive: DO NOT INTERVENE

The Watchdog was watching. But it was watching for Code Sight anomalies — his anomalies. Not for this. This was invisible to it. Or beneath its concern. Or something worse: the Watchdog couldn't see it at all.

"Zhang Wei." Li Hua appeared at his shoulder, backpack on. "Got everything. What's your face doing?"

"My face?"

"You get a look when you're reading something I can't see." She shifted the pack. "What is it?"

He closed the notification. Or it closed itself.

"Something in the building. Sublevel one. Below the parking garage."

"Monsters?"

"I don't think so."

She studied him. "That's worse, isn't it. When you don't think so."

He picked up a length of rebar. Tested the weight. A quest that shouldn't exist, authored by something that wasn't the System, pointing to a location underneath their feet. The Watchdog couldn't see it. The patch notes didn't mention it. The Test Framework v1.0 had no record of it.

Three layers of surveillance, and something had slipped through all of them.

"The Watchdog monitors me," he said. "But whatever sent that message, the System doesn't know it's there."

Li Hua zipped the backpack shut. "Then we go down there carefully."

"That's what I was going to suggest."

"I know. That's why I said it first."

They crossed back toward Building 7. Gray sky pressing low. In the distance, something howled — sustained, territorial, the sound of a creature that had claimed a city block and dared anything to challenge it.

Below Zhang Wei's feet, through concrete and steel and rebar, the hidden quest marker pulsed. Faint. Steady. A heartbeat in the code that no one else could feel.

Thirty days. One hundred sixty-three million dead. And something living inside the System that the System itself had never written.
