The sterilization corridor hummed like a jet engine. Disinfectant spray—smelling like a mix of bleach and cheap lemon—blasted from every direction, drenching Zahara Nasution. Zahara coughed hard, her eyes stinging. Her bone-white designer suit, which cost as much as a sports car, was now soaking wet, clinging to her body along with the washed-away remains of zombie blood. Her gold pistol had been snatched by a mechanical arm that had suddenly shot out of the wall the moment she’d fallen into the room.A green light flickered above the steel door in front of her. It slid open without a sound. Zahara stepped out, her breath still ragged. She found herself in a vast room that looked more like a concrete showroom than a boarding house. The floor was polished cement, the walls were lined with steel panels, and in the middle of the room sat a man on a red "Lion Star" plastic chair.The guy was wearing a faded t-shirt featuring a defunct political party and knee-length shorts. In hi

Morning in the bunker didn't come with a sunrise. It came with the harsh, buzzing hum of the LED ceiling lights flicking on at exactly 7:00 AM, accompanied by a digital rooster crowing through the intercom.Rangga stretched on his cot, popping his back. He had slept like a baby. It turned out that being encased in a titanium cube while the world ended outside did wonders for his insomnia.Across the room, Zahara looked like she had been dragged backward through a thornbush.She was sitting on the edge of the cheap folding sofa bed, staring blankly at the concrete floor. Her designer blazer was draped over a chair, smelling faintly of bleach and zombie guts. Her white blouse was wrinkled beyond repair, and her immaculate updo from yesterday was now a chaotic bird's nest. Her dark circles could rival a panda's."Morning, tenant," Rangga chirped, tossing his blanket aside. "Sleep well?"Zahara slowly turned her head. Her eyes were bloodshot. "The mattress feels like it's stuffed wit

The next morning, the bunker smelled like heaven. Specifically, it smelled like premium, freshly ground Arabica coffee. Rangga sat at his plastic folding table, taking a slow sip from a proper ceramic mug. He sighed in pure bliss. Across the room, Zahara was aggressively pinning a pair of faded Batman boxers to the indoor drying rack. She still looked like a disgruntled teenager in her oversized REBAHAN 4 LYFE t-shirt, but she was actually doing the chores without threatening to murder him. Character development."Host, you have 3500 System Points sitting in your account," the System’s voice chimed in his head. "What is this, a savings account? Spend it! Upgrade the bunker! An empty bank account builds character!"Rangga pulled up the green holographic interface."Alright, let's see what we can afford," Rangga muttered. "I'm tired of eating instant noodles on a plastic chair."He scrolled through the [BASE UPGRADES] menu. His eyes landed on a mid-tier option.[UPGRADE: Level 1

"The rules of the transaction were very simple, Siska," Rangga said, leaning his chair back until it creaked. He took a sip of his high-grade Arabica, looking through the rising steam with a flat, commercial indifference. "You eat my groceries, you help the building get its tax break. Or, in this case, a genetic core upgrade."Siska stood there, her manicured fingers trembling around a bucket of soapy water. "You want me to... stand in an armored alleyway... and scream until a giant, acid-pitting swamp monster tries to eat me? Abang, I’m literally five-foot-four and currently malnourished!" "You're not malnourished," Zahara chimed in from the stove, her voice as smooth as polished bone. "You ate half my crackers and bitched about the consistency of the oatmeal. You have plenty of storage fat. And you have high-frequency pipes." Zahara didn't even turn around. She was cleaning a 9mm gold-plated pistol she had 'confiscated' earlier from Rangga’s lockers, using a dish rag with unset

The transition between a cold slab of reinforced concrete and the humming life of the Hydroponic Wing was as abrupt as the arrival of the apocalypse itself. One moment, the bunker was an aesthetic of brushed steel and survival paranoia; the next, the western partition slid back to reveal a chamber saturated in violet and soft-spectrum green light.Rangga stepped inside first, the smell of damp earth and something unnervingly pure—oxygen—washing over his senses. It was a sterile, engineered scent, far removed from the stench of rot that perpetually haunted the Jakarta ruins. Behind him, Zahara and Siska hung back for a heartbeat, two women accustomed to high-rises and neon vanity, both seemingly hesitant to enter the inner sanctum of their salvation."Is this it?" Siska breathed, stepping through the doorway with her usual cynical slant, though her eyes were wide. "It looks like a science lab. Where are the actual vegetables?"Rangga tapped his terminal, bringing the central interfa
