The "Hive" was not a building. It was a network of narrow, limestone canyons that wound through the center of the Blackwood Expanse like a scar.

  The air here was thick with the smell of ammonia and rotting meat. The ground was covered in a sticky, white webbing that muffled footsteps.

  Julian stood on a high ridge overlooking the main canyon entrance. Below him, the shadows writhed.

  Hundreds of Dusk Spiders.

  They were crawling over each other, a carpet of chitin and venom. Some were small, Level 3 workers. Others were massive Level 8 soldiers like the one he had just killed.

  "Estimated count: 200+," Julian whispered. He checked the leaderboard again.

  1. Kaelen (Fire Mage) - 620 Points

  ...

  315. Julian (F-Grade) - 20 Points

  "Kaelen is burning them," Julian deduced. "Fire is effective against biological targets, but it consumes vast amounts of mana. He will burn out soon. I need a method that scales."

  He turned his gaze away from the monsters and looked at the canyon walls.

  They were tall, jagged pillars of sedimentary rock. Limestone. Porous. Brittle.

  He walked over to the nearest rock formation and tapped it gently with his tuning fork. *Ting.*

  The sound echoed, bouncing back and forth between the canyon walls.

  "Acoustic feedback loop," Julian noted, his eyes lighting up behind his glasses. "The canyon is a natural amplifier."

  He didn't rush down to fight. Instead, he spent the next twenty minutes climbing. He moved along the ridge until he found a specific spot—a narrow choke point where the canyon walls curved inward, creating a perfect parabolic reflector.

  Above this choke point hung a massive, unstable overhang of rock, tons of stone held up by centuries of erosion.

  "Structure integrity: 12%," Julian calculated. "It just needs a nudge."

  He pulled out his pouch of Mana Stones. He took **three** stones—a significant investment—and crushed them in his hand, absorbing the raw energy instantly.

  [Overcharge: 150%]

  [Warning: Mana toxicity rising.]

  Julian ignored the burning sensation in his veins. He jammed the **Sonic Lancet** into a crack in the rock wall.

  He didn't create a sharp cutting wave this time. He created a low, rhythmic hum.

  *Hummmmmmm.*

  At first, it was barely audible. But the sound waves bounced off the opposite wall, returned, and combined with the new waves coming from the fork.

  [Skill: Constructive Interference]

  [Target: Geological Resonance]

  The sound grew louder. It wasn't a noise anymore; it was a vibration that rattled the teeth.

  Down in the canyon, the spiders panicked. The vibration was driving their sensory hairs insane. They screeched and swarmed towards the source of the noise—directly into the choke point beneath the overhang.

  "Come on," Julian whispered, sweat dripping down his nose as he poured more mana into the fork to maintain the frequency. "Group up."

  The swarm thickened. Five hundred points worth of monsters were now packed into a space the size of a tennis court, climbing over each other to reach him.

  The vibration in the rock walls hit its peak. The frequency matched the natural resonant frequency of the limestone overhang above.

  The massive stone formation didn't crack. It began to *sing*. And then, the molecular bonds simply gave up.

  *CRACK-BOOM.*

  It sounded like thunder.

  Three hundred tons of rock detached from the cliff face.

  Julian pulled his tuning fork free and rolled backward, covering his head.

  The landslide crashed down into the canyon with the force of a meteor impact. Dust billowed up, choking the air. The screeching of the spiders was instantly silenced, replaced by the heavy, settling crunch of stone.

  The notifications scrolled past his vision so fast they blurred.

  [Level Up!]

  [Level Up!]

  Julian stood up, dusting off his grey robe. He looked down into the canyon.

  Where there had been a swarm of monsters, there was now a mountain of rubble. Crushed spider legs stuck out from the rocks here and there. Purple spirit tokens were floating out of the debris, dozens of them, drifting towards him like fireflies attracted to a magnet.

  "Work smarter," Julian said, his voice hoarse from the dust. "Not harder."

  He checked the leaderboard.

  [Freshman Trial Rankings]

  1. Julian (F-Grade) - 850 Points

  2. Kaelen (Fire Mage) - 640 Points

  Julian smiled. "Now, I have their attention."

  And that, ladies and gentlemen, is how you clear a dungeon with physics.
