The pungent smell of synthetic lemon was the first thing that hit Marsel's nose.
It wasn't the fresh scent of newly mopped floors that usually greeted him every morning at seven. This was the thick, chemical odor of spilled floor cleaner, mixed with something far more metallic and fishy. Blood. "Ugh, my head," Marsel groaned, trying to lift his body off the cold, sticky ceramic floor. The world spun. The long fluorescent lights on the ceiling of A-117 Supermarket flickered as if having an electrical seizure, creating a nauseating strobe effect. Bzzzt. Bzzzt. The electrical buzzing sounded like a giant fly trapped inside his ear. "Hey, who spilled So Klin here?" Marsel shouted, his voice hoarse. He clutched his throbbing head, then realized his hand was wet. Not water. Thick red fluid. His eyes widened. He stared at his palm. Blood. "Damn it," he hissed, his heart instantly pumping adrenaline through his body. "What is this? An earthquake? A robbery?" He looked around. The gondola shelves, usually neatly stocked, were now toppled like a failed domino setup. Sardine cans, instant noodle packets, and soy sauce bottles were scattered everywhere, creating a sea of consumer debris. At the end of Aisle 3, near the snack section, someone stood with their back to him. A familiar red-and-yellow uniform. It was an A-117 staff uniform. "Dika?" Marsel called out, trying to stand despite his shaky legs. "Dik! You okay? Help me up, you idiot. I think the cigarette rack fell on me." The figure didn't answer. Its shoulders twitched with an unnatural rhythm, as if the bones inside were being forcibly rearranged. A wet cracking sound came from its direction. "Dik?" Marsel took a step back, his manager's instinct screaming that something was wrong. "Dika, what's wrong with you? Stop messing around. The store is destroyed; Mr. Budi will freak out if he sees us just standing here." Dika turned slowly. Marsel held his breath. Dika's face... was gone. Or rather, it was covered by a metallic gray texture resembling a frozen computer glitch. His eyes were just two blinking points of blue light. His mouth hung wide open, dripping black saliva that sizzled when it hit the floor. Above his head, red text floated in the air, transparent yet real: [Ekorupt Drone - Lv. 1] "What the hell..." Marsel backed up again, bumping into a stack of promotional toilet paper. "Dik, what happened to your face? Did you put on an I*******m filter or something?" "Grrrr... Grrrrr..." The sound coming from Dika's throat sounded like a broken dial-up modem mixed with a wild animal's growl. "Okay, confirmed, you're not Dika," Marsel muttered, cold sweat running down his back. "I don't get paid enough to deal with staff possessed by robot ghosts." Dika—or the creature that used to be Dika—lunged. "Waaaa!" Marsel jumped aside, narrowly avoiding the attack. Dika slammed into the snack rack, causing dozens of chip bags to burst and scatter. Its movements were stiff and jerky, but its strength was clearly inhuman. The metal shelf bent as if it were made of wax. "Are you crazy?! What did you eat, Dik?!" Marsel yelled in panic. He turned and ran full speed toward the checkout area. "Help! Somebody! There's a maniac in Aisle 3!" There was no answer. Only faint screams from the back storage room and the sound of distant sirens wailing. Marsel leaped over a puddle of spilled cooking oil, his shoes squeaking loudly. Screech! He slipped, falling hard against checkout counter number 4. His ribs hit the corner of the desk. "Son of a bitch!" he cursed, wincing in pain. He looked back. Dika was already up again, walking with a fast, dragging gait. Behind Dika, emerging from the darkness of the dairy aisle, were two other figures. A woman in a house dress and the store security guard, Mr. Asep. Both had the same gray skin, with the text [Ekorupt Drone - Lv. 1] floating above their heads. "Mr. Asep too?" Marsel scrambled behind the checkout counter, his breath ragged. "What kind of plague is this? Digital rabies?" He searched for a weapon. Anything. But on the counter, there was only the EDC machine, plastic bags, and a handheld barcode scanner with a frayed cable. "Okay, Marsel, think," he whispered to himself, his hands shaking violently as he grabbed the scanner handle. "You're the manager. You have to manage this situation. Step one: don't die. Step two: fire Dika if I survive." Dika reached the counter, leaping over the conveyor belt with stiff movements. Its gray, sharp-nailed hand reached for Marsel's neck. "Don't touch me!" Marsel screamed. In reflex, he swung the handheld scanner with all his might toward Dika's head. THWACK! The impact was hard, but that wasn't what sent Dika flying. The moment the scanner tip touched Dika's metal-hard forehead, a burst of blue electricity exploded. ZING! Marsel's world went white for a moment. A mechanical voice, cold and emotionless, spoke directly inside his brain. [System Detected.] [Initiating Emergency Protocol...] [A-117 Checkout Scanner Connected to User Bio-Signature.] "Huh?" Marsel blinked, his vision returning. Dika was thrown into the gum rack, his body convulsing as if hit by a high-voltage shock. The scanner in Marsel's hand no longer looked like cheap plastic. It glowed with a neon blue light; luminous circuit lines crawled from the scanner handle up Marsel's arm, merging with his skin. "What is this?" Marsel stared at his hand. "Am I a cyborg?" "Grraaaah!" Mr. Asep, now an Ekorupt, roared and leaped over the next checkout counter, swinging his now-bent security baton. "Whoa, hold on, sir!" Marsel yelled, instinctively pointing the glowing scanner at Mr. Asep like a gun. "I haven't scanned your groceries yet!" A transparent blue holographic screen appeared before Marsel's eyes, blocking his view of Mr. Asep's horrific face. [CLASS UNLOCKED: FORTRESS MANAGER (LEVEL 1)] [Active Skill: Weakness Scan (Basic)] "Scan? I have to scan him?" Marsel shrieked hysterically. Mr. Asep was already swinging his baton. Marsel pulled the scanner's trigger. A red laser beam, like the one he usually used to check the price of rice, shot out and scanned Mr. Asep's body from top to bottom in a fraction of a second. BEEP! [Target: Ekorupt Drone (Former Security Guard)] [Weak Point: Left Knee (Old Gout Injury)] "Holy hell, the system knows Mr. Asep has gout!" Marsel exclaimed, astonished and horrified. Without wasting a second, Marsel kicked with all his might at Mr. Asep's left knee, which was marked by a flashing red circle in his new vision. CRACK! "Sorry, sir!" Mr. Asep howled—a painful digital sound—and fell forward, losing his balance. Marsel didn't waste the opportunity. He jumped onto the checkout counter, then kicked Mr. Asep in the face with his dress shoe, slicked with oil. The Ekorupt was shoved backward, colliding with the woman in the house dress who was just about to attack. They both tumbled among stacks of magazines and promotional chocolates. "Back off! All of you, back off!" Marsel brandished his scanner, trembling. "I... I have a barcode, and I'm not afraid to use it!" His breath hitched. His heart pounded so hard his ears hurt. He stood atop checkout counter number 4 like the captain of a sinking ship, surrounded by a sea of merchandise and monsters who used to be his neighbors and coworkers. Suddenly, all the lights in the supermarket went out completely. Pitch black. "Oh, come on," Marsel complained in the darkness. "Don't tell me the power's out! Hey, power company, work with me here!" Silence for a moment. Only Marsel's ragged breathing and the low growl of Dika, who was starting to rise again in the dark. Then, a low humming sound began. Not from the lights, but from the floor, the walls, and the metal shelves around him. Lines of blue light began to illuminate the ceramic floor, forming a giant, intricate circuit pattern that spread from the entrance to the back storage room. The light illuminated the faces of the Ekorupts, who stared hungrily at Marsel. But this time, the light didn't feel hostile. It felt... obedient. A giant dialogue box, as wide as the main entrance, appeared in the air right in front of Marsel's face. The text glowed golden, unlike the red color on the monsters. "Now what?" Marsel whispered, wiping the sweat mixed with blood from his temple. "Don't tell me I have to update Windows first." He read the text. [FORTRESS SYSTEM INITIATED] [Location: A-117 Supermarket] [Authority: Marsel (Fortress Manager)] [Status: Red Zone] "Fortress Manager?" Marsel laughed bitterly. "Does this come with a raise?" Dika's growl grew closer. He had already climbed the cigarette rack next to Marsel, ready to pounce from above. [Warning: Biological Threat Detected within 2-meter radius.] [Would you like to activate the Initial Defense Protocol?] [Y / N] "YES! Yes, you idiot! Why are you asking?!" Marsel yelled, pressing the 'Y' button in the air with a trembling finger. CLANG! The steel rolling door behind the counter—the one that usually jammed and needed to be hammered shut—suddenly slammed down at supersonic speed, hitting Dika squarely in mid-air before he could touch Marsel. CRASH! Dika was thrown back, smashing into the supermarket's front glass wall, shattering it into a thousand cracks. The other Ekorupts retreated, blinded by the blue light radiating from every corner of the store. Marsel slumped onto the checkout counter, his legs weak as jelly. He hugged his scanner tightly. He looked around. The supermarket walls were now overlaid with a transparent blue light grid. The merchandise shelves vibrated subtly, as if alive. A final message appeared, pulsing slowly in time with Marsel's slowing heartbeat. [A-117 Supermarket. Activated as Defense Core.] [Wall Upgrade (Level 1) available.] [Welcome to the Apocalypse, Mr. Manager.] *Latest Chapter
Chapter 11 - Preparing the Last Bastion
The tick-tock sound of the digital holographic clock floating in the center of the room felt like a sledgehammer pounding Marsel’s nerves one strike at a time.[BETA WAVE COUNTDOWN: 06:14:22]Six hours left. Just six hours before five hundred organized monsters would flatten Supermarket A-117 into the ground.“Damn,” Marsel muttered, his eyes red and burning from staring at the System’s shopping interface for too long. “Everything’s more expensive right before a war. Does this System use surge pricing like ride-hailing apps when it rains or what?”He stood in front of the virtual display labeled [Fortress Shop]. The XP he’d painstakingly collected from slaughtering Scavengers and Berserkers yesterday totaled 1,250 points. A decent amount under normal circumstances, but it felt like pocket change when facing the apocalypse.“Mas,” Nana called from the medicine aisle. She was sitting cross-legged on the floor, surrounded by alcohol bottles, bandages, and light-blue mana potions she’d br
CHAPTER 10 - THE WOLF IS COMING
Cold vapor plumed from Marsel’s mouth every time he exhaled. The temperature inside Warehouse 5’s Cold Storage was set at minus fifteen degrees Celsius.In the middle of the room, tied to a meat rack support pole with industrial cable ties, Baldy was shivering violently. His lips were blue, not from Tyrex’s bruises, but from mild hypothermia."I... I told you everything..." Baldy babbled, his teeth chattering like a broken typewriter. "Let me go... it's cold...""Not everything," Marsel said coldly. He sat on an apple crate, holding Baldy's leather jacket, which he had confiscated. The jacket smelled musty, of sweat, and—most importantly—had a strange residue of purple slime on the back.Tyrex stood behind Baldy, folding his tree-trunk-sized arms across his chest. He wasn't cold. His passive **[Guardian]** skill seemed to grant him absurd body temperature resistance. In fact, he was happily licking an orange popsicle he had found in the corner."My Liege," Tyrex said, crunching the ic
CHAPTER 9 - HUMAN SHIELDS
The proximity alarm sounded like a panicked heartbeat—fast, rhythmic, and deadly.BEEP-BEEP-BEEP-BEEP!Marsel slammed the server room door open, his eyes immediately locking onto the monitor wall displaying the 360-degree CCTV feed around Supermarket A-117."They're back again?" Nana asked, running in behind him, carrying a medical bag."Worse," Marsel growled, his fingers dancing over the holographic keyboard. He zoomed in on Camera 3 (Front Parking Sector). "Look at that."On the blue-glowing monitor screen, a line of people was visible. About thirty of them. But it wasn't their numbers that made Marsel's blood boil.The front line wasn't armed Scavengers. They were ordinary citizens—old men, mothers in torn house dresses, crying teenagers. Their hands were tied in front of them, and ropes around their necks were being pulled by the Scavengers in the second line.They were being used as human shields."Bastards," Marsel hissed. "They know we have the Wall Shockwave. They know I won'
CHAPTER 8 - LUCKY STUMBLE
"The last drop," Nana hissed, flipping the glass jar upside down over the checkout counter.Only fine brown powder fell out, then vanished, carried away by the breeze from the central air conditioning, which was only running at half power."It’s gone?" Marsel asked, his voice sounding like a man who had just received a death sentence."All gone, sir. Kapal Api, Good Day, Indocafe... everything is zero," Nana said, setting the jar down with a sad *thunk*. "Our caffeine stock is officially bankrupt."The atmosphere in the emergency break area instantly turned funereal. For apocalypse survivors, coffee wasn't just a drink. It was mental fuel. Without coffee, Marsel’s sanity, which was required to manage inventory, defense strategy, and Pak Budi’s ego, was hanging by a thread."This is a management catastrophe!" yelled Pak Budi from the corner of the room. He was sitting atop a stack of instant noodle boxes, dramatically massaging his temples. "How am I supposed to formulate macro-strateg
CHAPTER 7 - THE WILD LAW OF LitRPG
The midday sun felt like an overly bright stage spotlight, glaring down on the cracked asphalt in front of the A-117 Supermarket. For Marsel, however, the most dazzling and annoying light was the line of holographic text floating in his field of view.**[Marsel - Fortress Manager Lv. 2]****[XP: 995/1000]**"Just five points short," Marsel grumbled, kicking a pebble. "Only five points. The stingy System."It had been two days since the Scavenger attack. Bullet production from the pizza oven was running smoothly, and food stocks were secure thanks to Mr. Budi’s 'creative' management (who turned out to be adept at mixing canned sardines with instant noodles). But Marsel’s level was stagnant. The Ekorupts around the supermarket had been wiped out by Tyrex during the morning patrol, and they only gave a measly 1 or 2 XP."We have to go out," Marsel stated firmly, tightening the straps of his backpack, which was loaded with ammo and first aid supplies.Next to him, Tyrex was flexing his ch
Chapter 6 - Fortification and Recycled Ammunition
The smell of burning plastic mixed with rotting meat filled the A-117 Supermarket Food Court area. Thick black smoke billowed from the emergency chimney Marsel had just installed, punching through the roof ventilation."Marsel, is this really safe?" Nana asked, covering her nose with the collar of her grubby nurse uniform. "It smells like a truck tire burned with satay seasoning.""Safe or not, this is the only way we won't die for nothing if there's another attack," Marsel replied without looking up.He was busy tinkering with the control panel of an industrial Moretti Forni pizza oven that had been heavily modified. Neon blue circuit cables dangled from Marsel’s Scanner, merging with the oven’s motherboard. Inside the glowing red-hot oven, it wasn't dough and mozzarella cheese being baked, but pieces of the Spider Ekorupt legs they had slaughtered two days prior."Internal temperature reaching 400 degrees System," Marsel muttered, his eyes scanning the lines of code scrolling rapidl
