When Jack finally regained consciousness, the cold tiles of the shower felt oddly comforting against his back. As he slowly opened his eyes, a disorienting scene greeted him – black stains marred the bathroom floor, clinging to his body and emitting a pungent odor that invaded his senses.

"What the hell is all this stuff?" Jack muttered to himself, blinking away the remnants of his dazed state. The surreal aftermath of the gene awakening left him bewildered, and he wasted no time in springing into action.

With a sense of urgency, Jack began cleaning the mysterious black stains that covered both his body and the bathroom floor. The pungent smell lingered, an unsettling reminder of the transformative process he had undergone just moments ago. As the stains vanished under the force of his cleaning efforts, Jack couldn't help but wonder about the nature of the changes he had unwittingly unleashed.

Once satisfied that the bathroom was restored to its original state, Jack emerged, the towel draped around his waist. He took a moment to dry his hair and pondered the peculiar turn of events. However, the oddest revelation awaited him as he reached for his clothes.

His clothes, purchased just a month ago, now felt remarkably short. Confusion etched across his face, Jack swiftly examined himself, discovering that he had not only become taller by about 5 centimeters but also underwent a remarkable physical transformation.

As he stood in front of the mirror, the once-familiar face now appeared altered. His body boasted defined six-pack abs, and his shoulders had broadened, lending an athletic strength to his physique. Jack's eyes, once brown, had transformed into an inky black, deep and mysterious like the ocean's abyss. His facial features, though retaining a semblance of familiarity, had become more chiseled and undeniably handsome, even his little brother grows a bit taller.

Jack's gaze met his reflection, and a wave of disbelief washed over him. "What just happened?" he wondered aloud. The mirror offered no answers, but the profound changes to his appearance spoke of a metamorphosis that defied understanding.

Shaking off the initial shock, Jack surveyed himself with a mix of awe and uncertainty. The gene awakening, triggered by the advanced gene potion, had left an indelible mark on both his physicality and his perception of self. The once ordinary man had become something extraordinary.
