A passage back to Earth

With both hands gripping the hilt, Roxy brought the weapon down with a powerful, decisive strike. The blade sliced cleanly into the ant mutant's skull, sinking deep and emitting a sickening crunch as it met bone. The creature let out a final, agonized shriek, its mandibles clicking frantically before its body convulsed and collapsed into a heap of shattered limbs.

Roxy wrenched her sword free from the creature's head, flicking its blood from the blade with a practiced, fluid motion. Her gaze swept over the cave, taking in the scattered remains of defeated mutants with a cold, unbothered expression.

Finally, her gaze shifted to Isaac, who stood in stunned silence, his face glistening with sweat and his breath coming in shallow, ragged gasps—a mix of fear and amazement written plainly on his face.

"Who...who are you? What are you?" Isaac stammered, his voice quivering as he struggled to comprehend the deadly force before him.
