The Astral Hound lunged, its mercury-liquid body elongating into a whip-like blade that sliced through the air with a high-frequency hum. Kaelen felt the displacement of space before the strike even landed.
[Warning: Kinetic Impact Imminent!] [Activating Sovereign Mantle: 100% Output.]
The mercury blade struck an invisible wall of gravity inches from Kaelen's face. Sparks of violet and silver erupted as the two forces clashed. Kaelen's feet skidded back on the metallic floor, leaving deep furrows in the silver plating.
"Sora, stay down!" Kaelen roared.
He didn't just want to destroy this thing. He wanted to own it.
Kaelen lunged forward, ignoring the Hound's secondary appendages. He let the beast's liquid-metal claws sink into his left shoulder. Pain flared, white-hot and searing, but it was exactly what he needed: Physical Contact.
"I've got you," Kaelen hissed through gritted teeth.
[Absolute Consumption: OVERDRIVE.] [Subject: Astral Guardian (Living Metal).] [Initiating 'System Forging'...]
The Hound's three red eyes flickered. It tried to retract its limb, but the mercury was already being dragged into Kaelen's body. The liquid metal didn't just enter his bloodstream; the System began to rewrite Kaelen's genetic code in real-time.
His left arm began to bubble and warp. The flesh was consumed, replaced by a swirling, semi-solid lattice of obsidian and mercury.
[Evolution Process: 40%... 70%... 100%!] [New Weapon Grafted: 'The Void-Shard Prosthetic'.] [Properties: Formless. Conductive. Devouring.]
With a primal scream, Kaelen swung his newly transformed left arm. It shifted mid-air from a fist into a massive, jagged cleaver.
SHRED.
The Astral Hound was torn in half. Before its remains could liquefy and reform, Kaelen's new arm surged forward like a living parasite, tendrils of dark mercury wrapping around the beast's core and dragging every last drop of essence into Kaelen's chest.
[Level UP!] [Level 13 -> Level 15] [Skill Unlocked: 'Morphing Arsenal' (Rank: Growth).]
Silence returned to the hallway, broken only by Kaelen's heavy breathing. His left arm was now a sleek, terrifying limb of matte-black metal that shimmered with a faint violet light. With a thought, it retracted into the shape of a normal human hand, though it remained cold to the touch.
Sora stood up, wiping silver blood from her lip. She looked at Kaelen's new arm with a mixture of respect and genuine fear. "You're not just eating mana anymore, Kaelen. You're eating the world itself."
"It's what the System wanted," Kaelen said, flexing his metallic fingers. He could feel the blueprints of a thousand different weapons stored within the limb's memory. "And it's what we need if we're going to survive the Astral Sea."
[New Objective: Locate the 'Bridge' of the Silver Sentinel.] [Alert: Long-range sensors have picked up a high-speed pursuit vessel.] [Identity: The Star-Hunter, 'Krax the Merciless'.]
Kaelen looked toward the end of the dark corridor. "We're being hunted, Sora. But let them come. I need a test subject for my new blade."
