Jack approached the beast's remains, his body battered and bruised but still brimming with energy. His sword glowed faintly, its edge reflecting the dark essence swirling in the air around the fallen creature. He plunged the blade into the beast's chest, cutting through layers of tough flesh until he hit its core.
"Found it," he muttered, pulling the dark, swirling core free from the corpse. The core was the size of his fist, its surface rippling with dense, malevolent energy.
Isaiah stepped closer, his golden light dimly illuminating the core. His brows furrowed as he examined it. "Strange... it barely used its dark element in the fight, yet this core is brimming with dark energy. It's almost like the beast was holding back, mocking us."
