The Most Satisfied Reincarnate

[The Blood of the Flying Lizard has been successfully injected into the host's body!]

[WARNING! Strong resistance has been detected in the host's blood!]

The room was shrouded in an eerie atmosphere, filled with cauldrons brimming with an assortment of blood types. Desmond sat in a worn chair, his hand tightly clutching a syringe with a long, sharp needle that had pierced his right palm. As the needle penetrated his flesh, a series of wrinkles sprouted across his forehead, resembling mushrooms on damp earth.

Magenta eyes gleaming, Desmond fixated his gaze upon the emerald blood slowly diminishing within the syringe barrel, watching as it coursed through the hollow space within the needle and eventually tainted his veins.

Like a vivid green dye dissolving in crystal-clear water, the unique blood swiftly permeated his entire hand, transforming his once-vanilla skin into a grotesque, swollen mass of green. The veins on his hand twitched and pulsated, swelling with each passing moment. Simultaneously, an intense onslaught of pain assailed Desmond's mind, causing his trembling lips to release a pained groan.

"Argh..." Amidst the relentless agony, Desmond clenched his lower lip, drawing a bead of scarlet blood that trickled down, staining his trousers before meeting the floor. Upon closer inspection, his blood was no longer a pure crimson hue; now, it bore traces of thick, green speckles, marring its otherwise familiar appearance.

Beads of sweat formed on Desmond's forehead as his vision gradually blurred, yet he strained to keep his hands steady, fixating on the remaining green blood lingering in the syringe's chamber.

However, the sensation of his brain being rent asunder shattered his focus, causing his body to weaken. Amidst his desperate struggle against the pain, a peculiar shadow caught Desmond's attention from the corner of his eye. It emerged from his body, enveloping his eyes and mouth, while a faint image of a tail snaked around his neck.

The constriction tightened around his throat, disrupting the flow of energy throughout his body like tumultuous waves crashing upon the shore.

The grip of the faint tail intensified, constricting his airway and gradually depriving his lungs of precious oxygen. As his throat constricted, his eyes reddened, and his breath grew scarce. Faced with this dire predicament, Desmond's desperate resolve to dispel the haunting shadow waned, and his consciousness slipped into an abyss of unknown dimensions.

Like a ship drifting farther from the safety of land, his awareness sank deeper into an unfathomable space, only to be greeted by an abrupt surge of scorching heat, akin to searing coals upon his body. The high temperature felt as though his entire being were immersed in boiling water.

To compound matters, the blood coursing through his veins reversed its flow, drawing the newly introduced green blood inward, gradually assimilating its nature into a familiar shade of crimson.

While Desmond remained bewildered by these sudden metamorphoses, a faint image of a black dragon materialized within his mind. The creature stared at him with an open maw, revealing a set of obsidian, formidable teeth. A smirk adorned the dragon's visage, seemingly taunting Desmond for his apparent inadequacy in handling his own tribulations.

Yet, Desmond's keen perception noticed a hint of green blood smearing the dragon's mouth.

Despite the black dragon's vexing behavior, Desmond harbored a deep-seated understanding that this enigmatic creature had indeed rendered assistance. Before he could voice his thoughts, the scene fragmented like a shattered mirror, replaced by a translucent display emanating from the system before him.

"Ohh!" Desmond exclaimed, his eyes lighting up as he noticed the new addition to his stats. The previously hazy vision dissipated, and a surge of alertness coursed through his body, rousing him from the drowsy sensation. He focused his attention on the new panel, his eyebrows raised in curiosity.

"Sharp claw? A claw in my hand?" Desmond contemplated, his mind devoid of any sudden influx of knowledge. Attempting to seek clarification from the system yielded no response, leaving him with no choice but to unravel the mystery himself.

"If this ability is called 'sharp claw' for a reason, do I need an actual claw to activate it, or can I utilize it as it is?" Desmond pondered aloud, his gaze shifting between the skill name and his hands, searching for answers. With a mix of intrigue and uncertainty, he decided to replicate a scene from a famous movie he recalled from his past world.

Raising his hand, palm facing inward, he clenched his fist, hoping to summon the claws from the back of his hand.

"It's not working?" Desmond frowned, disappointment clouding his expression. He scrutinized the skill name once more before embarking on another experiment. "What about this?"

Focusing his thoughts solely on his nails, he felt an uncomfortable sensation as if his hands had suddenly grown heavier. "Woah!" Desmond exclaimed, taken aback by the transformation. His nails had elongated from a mere 5mm to an astonishing 300mm, and instead of the typical white hue of human nails, they had transmuted into dark black metal.

Stunned by the sight before him, Desmond took a moment to absorb the marvel of his newfound claws. The ensuing moment, he attempted to wave his hands, inadvertently striking the table in front of him. The resulting clanging sound and the heavy thud reverberated through the room.

"What..." Desmond's voice trailed off as he gazed upon the broken table, a deep claw mark etched upon its surface. His disbelief lingered as he examined his nails. "Hard like steel," he murmured, excitement brimming within him. Without hesitation, he swung his hand again, but this time his target was a nearby cauldron.

Crash! The cauldron shattered into countless pieces of black wood. Witnessing this display of power, Desmond marveled at the durability of his nails, likening them to the famed material, Silveral.

"Amazing, simply amazing!" Desmond's face beamed with joy as he regarded his hands as the most precious of treasures. Intrigued by the possibilities, he decided to put his new nail skill to the test, both against his elemental swords and the scales of various creatures.

...

After several minutes of experimentation, Desmond let out a sigh and surveyed the length of his nails, shaking his head. "Though their power rivals that of Silveral, their length poses a hindrance. If only they were a bit shorter, they would serve as a formidable weapon for stealthy attacks."

As soon as Desmond voiced his thoughts and shifted his gaze to his hands, his nails obediently shrank to 250mm. The sudden transformation left him momentarily stunned, his brain struggling to process the reality before him. "Is this real? Can I adjust the size of my nails?" Still grappling with disbelief, he dared to envision a length of 1000mm.

Boom! Like a heavy rock plummeting from a great height, the wooden floor easily succumbed to the force of his nails, buried deep within its surface. "Incredible," Desmond mused, wiping the sweat from his forehead. Despite his complaint, his wide grin and labored breath revealed his true sentiments.

...

After indulging in various tricks and tactics for several minutes, Desmond finally found contentment. It was only when he glanced back at the transparent screen that he noticed yet another change in his stats, aside from the newly acquired ability. "A percentage! There's progress in my class!" he exclaimed, his voice filled with a mix of surprise and satisfaction.
