The colossal, disembodied voice vanished, leaving behind a silence more profound and terrifying than the screams that had preceded it. The new laws of reality settled over the world like a physical weight. In the dusty, hallowed halls of the Central Library, Martha Pembrook stared at Kairo, her face a mask of disbelief and horror.
"The First Floor?" she whispered, her voice trembling as she struggled to comprehend the psychic message. "The Tower of Ascension? What does that mean? What is this place?"
Kairo looked away from the barricaded window, his golden eyes holding no trace of the shock that gripped Martha. He had heard this speech before, though the wording was slightly different, more aggressive. The acceleration he'd noticed was real.
"It means exactly what it said," he stated, his voice as cold and hard as granite. "This world, our Earth, is no longer the center of anything. It's the starting line. A tutorial level in a game so vast we can't comprehend it. There are other floors, other worlds, stacked above us in this 'Tower.' To survive, we have to prove our worth. To thrive, we have to climb."
The clinical explanation offered no comfort. "Climb to where? And what happens if we don't? Purged? What does that mean?"
"It means we die," Kairo said, without a flicker of emotion. "It means the System, whatever it is, erases us for failing the test. The only way is up. That has always been the only way."
Martha sank into a chair, the weight of this cosmic revelation crushing her. She was a librarian, a creature of logic, order, and quiet contemplation. Her world had been violently replaced by a savage game of gods, and her only guide was a terrifyingly competent teenager who spoke of worlds and death with the detachment of a seasoned academic. She looked at the pile of books Kairo had chosen, her "contract" suddenly feeling like the only piece of solid ground in a universe that had turned to quicksand.
"I... I will begin cataloguing," she said, her voice small but firm. It was an act of defiance, a choice to impose order on at least one small corner of this new, mad world. She had accepted her role.
As night fell, a deep, unnatural darkness enveloped the ruined city. The library became an island of tense silence. Kairo did not sleep. While Martha worked under the dim light of a battery-powered lantern, her librarian's discipline overriding her fear, Kairo began his own work. He spread the books she had gathered across a large table, his mind a ravenous engine of analysis.
He wasn't just reading. He was synthesizing. He absorbed complex principles from a university-level chemistry textbook, cross-referencing them with schematics from an electrical engineering manual. His hands, which minutes before could wield a sword with deadly grace, now sketched delicate diagrams onto a notepad. He was designing a directional claymore mine, using potassium nitrate from fertilizer found in the library's rooftop garden, sulfur from a chemistry set in the children's science section, and a simple battery-powered initiator. It was old-world knowledge, reforged into a new-world weapon.
His focus was absolute. He also spent time in quiet contemplation, not resting, but cycling the cool Aether-laced mana through his body. He felt the pathways of his new class, familiarizing himself with the hum of his [Blade Aura], practicing his [Aether Step] in short, silent bursts within the confines of a large, empty room until the movement was an instinct, not a thought.
The first attack came just after midnight.
It started as a faint, dry scratching against the main barricade. Then another. Within minutes, the sound had multiplied a hundredfold, a skittering, scraping cacophony that grated on the nerves. Kairo was instantly on his feet, his Runic Blade in hand.
"What is it?" Martha whispered, rushing out from the archives, her face pale.
"They're back," Kairo said, moving toward a small peephole he had drilled in the barricade. "And they've brought friends." He motioned her back. "Go to the safe room in the basement. The one we prepared. Do not come out, no matter what you hear."
She hesitated, then nodded and fled.
Kairo peered through the hole. The street outside was swarming with them—a writhing sea of Aether Imps. But this time they weren't a chaotic mob. They moved with a clear, directed purpose, their attention focused solely on the library. And commanding them from the rear was a new type of creature. It was taller than the other imps, slender and disturbingly humanoid, with long, gangly limbs and a disproportionately large head that ended in a gaping, toothless maw.
He activated [Scan].
[Imp Shrieker]
Level: 5
Class: Commander
Abilities: [Piercing Screech], [Commanding Aura (Passive)] - Increases aggression and coordination of nearby lesser imps.
Description: A support-type monster that directs imp hordes. Weak in direct combat, but extremely dangerous when protected.
Just as he finished reading, the Shrieker let out a high-frequency scream that shattered the remaining windows on the upper floors. The imps surged forward, throwing themselves against the main doors with renewed frenzy. The oak tables groaned under the immense pressure. A weaker barricade on a side window began to splinter.
"The old world's rules are dead," Kairo murmured to himself. "And the new ones reward aggression."
He didn't wait for them to break through the main entrance. He raced to the side hall where the window was failing. He stood in the narrow corridor, a perfect fatal funnel. The makeshift barrier of bookshelves and desks shattered, and the imps began pouring through.
Kairo became a whirlwind of blue light and dark steel. His [Blade Aura] hummed, his sword cleaving through the creatures as if they were made of paper. He didn't take a single step back, holding the narrow choke point with inhuman efficiency. For every imp he cut down, two more scrambled over its dissolving corpse.
He used [Aether Step] not to retreat, but to advance. In a flicker, he was past the first rank of imps and beside the window, his sword a blur. He created a perimeter of death, preventing them from gaining a foothold inside the library. Down in the basement, Martha could hear the carnage. Unable to simply hide, she found the library's old PA system, which was connected to a backup generator. With trembling fingers, she flicked it on and pressed the microphone button, sending a deafening burst of static feedback screeching through the outdoor speakers at the opposite end of the building.
The tactic worked. A third of the horde, disoriented, broke off and swarmed toward the new sound. It was the opening Kairo needed. He burst through the broken window, [Aether Step] carrying him over the heads of the imps, and landed silently on the street. His target was the Shrieker.
The command monster shrieked in alarm as Kairo appeared before it. It was fast, dodging his first strike. But Kairo was faster. He anticipated its retreat, using another [Aether Step] to cut off its escape route. The Shrieker lashed out with its long claws, but Kairo parried the strike with contemptuous ease, his blade sliding up its arm and plunging deep into its chest.
With a final, gurgling cry, the Shrieker fell.
[You have slain an Imp Shrieker!]
[+250 EXP]
The moment it died, the [Commanding Aura] vanished. The rest of the imp horde descended into confusion, their hive mind broken. They began to scatter into the darkness. Kairo didn't let them escape, methodically cutting down the stragglers.
When it was over, he stood alone in the silent, body-strewn street.
[You have gained a level!]
[You are now Level 4.]
[Your skill, Aether Step, has grown through repeated, successful use.]
[Aether Step has reached Level 2.]
He checked the skill. Its mana cost had decreased by 10%, and its range had increased slightly. Small gains, but they would accumulate.
He walked back into his fortress, the damage minimal thanks to his choke-point tactics and Martha's timely distraction. He looked at the breached window, then back out at the empty street. This wasn't a random attack. The first night of the "real game," and his sanctuary, a point of order and stability in the chaos, had been deliberately besieged.
A chilling realization settled in his mind. The System wasn't a passive observer. It was an active, adversarial force. It was culling not just the weak, but the complacent. It punished those who sought to hide.
"You were right, Martha," he said to the empty hall, his voice resonating with a newfound certainty. "This is the rule of the jungle."
He looked at his Runic Blade, still humming with power.
"And in the jungle, you can't just build a den and wait. To survive, you have to be the apex predator. You have to attack."
His decision was made. The library was a resource, but it could not be home. His next target was clear. It was time to return to his warehouse and conquer the dungeon that was blooming in its depths.
