It was a dense forest, adorned with towering ancient green trees, each one bearing the weight of countless years, as evidenced by their dark brown barks etched with various scratches and cracks. These trees stood as resilient sentinels, having weathered the trials of time while remaining steadfast against its relentless onslaught. They proudly faced the sun, their branches forming a protective canopy that served as a sanctuary for the myriad life forms dwelling beneath.

This was a place teeming with the vibrant energy of nature. Various shades of green blanketed the earth beneath, a testament to the ongoing struggle between the verdant life and the earthy tones. Despite the challenges, both large and small mountains had risen, disrupting the greenery blanket only to be adorned with a new covering of lush green leaves. In this part of the forest, it seemed as though the forces of nature had emerged triumphant, transforming the once-brown earth into a canvas of vibrant green hues.

The dense congregation of trees and the abundance of green leaves obscured the blue sky, creating an almost nocturnal atmosphere within the forest. Yet, rays of sunlight managed to pierce through gaps in the canopy formed by the towering trees, casting pockets of illumination on the forest floor. It was a scene that blended the tranquility of a dark night with the subtle interplay of sunlight filtering through the lush foliage, creating a mesmerizing tapestry of shadows and light in the heart of the ancient woods.

Untouched by mankind, the forest pulsated with life. The melodious tunes of small birds and insects created a serene backdrop in this mysterious sanctuary. Amidst the symphony of nature, occasional shrieks and growls pierced the tranquility, reminding all that this seemingly peaceful place was, in fact, a battlefield, fraught with daily toils and challenges.

In the heart of this untamed wilderness, where survival favored the mighty, a boy lay peacefully asleep on the verdant cushions. Unbeknownst to him, danger lurked in the dark corridors of the dense forest. His body emitted a soft glow, a medley of colors that contrasted with the dominating green of the surroundings. As the glow gradually subsided, the features of the young boy's face emerged.

His hair was shiny and jet black, overgrown enough to partially conceal his eyes and ears. A small oval face exhibited thin yet prominent jawlines. Despite being slightly above average in height for his age, he possessed a slender figure. A rare, peaceful smile graced his face, giving him a handsome yet stern appearance. It seemed as though the ambient sounds of the forest did little to disturb this youth's dreamland, preserving the tranquility amidst the wild chaos.

Several moments passed, and the boy remained peacefully unaware of the predicament surrounding him. Suddenly, a rustling in the bushes near him disrupted the stillness. The foliage shook, and from within, a vibrant blue, gooey creature leaped out. It seemed to be a living entity, likely native to this enigmatic forest. This creature resembled a sphere of semi-solid substance, lacking any permanent shape or defined size.

The creature exhibited a bouncy and jiggly nature, with its body undulating as it moved from one spot to another. It appeared impervious to pain, its form maintaining a round, soft, and appendage-free structure. The mystery of how such a creature traversed the forest remained, a question that only researchers could hope to answer.

Continuing its playful bouncing, the creature gradually approached the still-sleeping boy. The intent behind its movements remained unclear — would it merely inspect the foreign element within its domain, or might it perceive the sleeping boy as an invader, prompting a mindless frolic or a potential attack? The outcome of this encounter hung in the balance, as the bouncy ball of mystery drew closer to the unconscious youth amidst the ancient trees.

The creature came to an abrupt stop near the boy, its squishy body showing a distinct motion as it ceased bouncing. Circling around the boy's body, it then, after what seemed like contemplation in its jiggly mind, jumped onto the face of the still-sleeping boy. Its wet, slimy, and bouncy body splashed onto the boy's face, covering it entirely.

Feeling the unexpected weight and wetness, the boy reacted swiftly, lifting both hands and delivering a hard slap to his own face. Startled, he jolted awake, only to find the blue bouncy ball had perished from the impact, slipping off his face and leaving behind a blue stone-like object in his hand.

With a mix of surprise and curiosity, the black-haired boy inspected the wet, slimy residue on his face and then turned his attention to the blue stone. Still not fully aware of his surroundings, he suddenly looked up, rotating his neck to survey the area. As if attempting to dispel the notion that it was all a dream, he closed and reopened his eyes, blinking several times, yet the scenery persisted.

Once again, he gazed upward, taking note of the towering, colossal trees and the occasional beams of light filtering through the gaps, indicating the presence of the sun. The realization slowly dawned upon him that this surreal environment was, indeed, his current reality.

"Where am I? What is this place?" Black-haired boy Alex blurted out, his first words echoing through the mysterious forest. The realization hit him, confirming that he was, indeed, Alex.

His initial assumption of being kidnapped and transported to an Earth-like forest was dismissed as he observed the blue substance on the ground and examined the blue stone in his hand. Although the creature that produced them was no longer visible, he identified it as a low-level monster, a Slime, with the blue stone serving as its monster core.

Contemplating the possibility of being in another world, Alex was eager to dispel his doubts. He examined himself, still clad in his school uniform— a full-sleeve white shirt with a dark blue blazer and matching pants. Aside from his clothes, he found himself devoid of any additional belongings. Alex theorized that perhaps his clothes had become one with his body during the transportation process, explaining why they remained intact.

After securing the blue stone, now identified as a monster core, in his pocket, Alex swiftly rose from his initial resting place. Conducting a thorough check of his body for injuries, he moved his limbs to ensure everything was in order. Satisfied with his physical condition, he ran in a circle, a final check, before coming to a stop to survey his surroundings once more. The dense forest stood as an enigmatic backdrop, inviting further exploration and discovery.

Surrounded by the impenetrable expanse of the dense forest, Alex found himself in a realm mostly shrouded in darkness, with intermittent patches of sunlight filtering through the thick canopy above. The atmosphere carried an innate tranquility, accompanied by the melodious tunes of unseen creatures. However, for Alex, the peaceful ambiance raised red warning signals, as he was an outsider in this foreign and mysterious place.

His primary objective now was to confirm his theory of being in another world. To substantiate this, he needed to discover something unknown—whether a creature, plant, or anything unfamiliar. However, venturing deeper into the dense unknown was not a decision to be taken lightly. Desiring a vantage point, he considered climbing the towering trees, but their height proved insurmountable.

Determined to explore, Alex decided to enter the heart of the forest. Before doing so, he sought to arm himself against potential threats. Scanning his surroundings, he discovered a thick branch, nearly a meter in length. After cleaning and refining it for better control, he swung it around, finding it manageable in weight and length.

In preparation for potential encounters, Alex fashioned a makeshift spear by scratching the one end of the branch with a flat sharp stone, creating a pointed tip for penetration. Additionally, he collected small, dense stones for use as throwables. Armed with these rudimentary weapons, he felt a sense of readiness to step into the unknown depths of the forest, prepared to face whatever challenges lay ahead.

Surveying the forest, Alex found no discernible difference in either direction. Deprived of the sun's guidance and uncertain about the nature of this world, he decided to forge ahead in the direction he faced. To avoid getting lost in the darkness of this labyrinth-like forest, he took precautionary measures. Collecting branches, he arranged them on the ground to create a distinct shape, marking his current position marked. In addition, he used the flat stone from earlier to mark the trees, ensuring a trail to follow.

As he embarked on this uncertain journey, Alex's face bore an expectant expression, revealing a readiness for whatever lay ahead. Despite the uncertainty, he exuded strength. A proficient fighter with a background in various martial arts and combat techniques. He had delved into the realms of magic and the supernatural, seeking those elusive powers within the martial arts he practiced. As he had believed in magic and the supernatural, Alex had even explored the cultivation of Qi, drawing inspiration from the practices of monks. Thus, armed with physical and mental fortitude, he ventured forth into the unknown, prepared to confront the mysteries of the dark forest.

Without further hesitation, Alex took the first steps into his new life in this unfamiliar place. Firmly clutching the makeshift spear, nothing more than a sturdy branch, he proceeded cautiously. Marking the trees with his impromptu tools, he maintained a vigilant gaze, ever watchful for any unexpected surprises.

Suddenly, a nearby bush shook, and a blue, bouncy mass emerged, leaping out with boundless energy. It wasn't far from his starting point, and in that moment, Alex found the proof he sought. He had indeed transmigrated to another world, a magical realm he had yearned for all his life. Excitement lit up his face, the realization that he could finally share the truth about the existence of magic.

However, amidst his newfound joy, thoughts of his family surfaced, their faces appearing in a blurred montage. Concern for their well-being tugged at him, and he couldn't help but wonder about their reactions to his sudden disappearance.

"Are they alright? They should be alright... perhaps a bit concerned about me," he sighed, contemplating the uncertainties that lay ahead.

Focusing on the immediate situation, Alex set aside thoughts of his family for the moment. As the jumping slime emerged, he came to a halt, readying his makeshift spear. The slime, whether aware of him or not, continued its lively bouncing. Alex carefully positioned the spear, and with a determined thrust, he aimed at the slime. The first attempt missed, barely grazing the surface. Unfazed, Alex reset his stance, concentrating on his target. This time, the pointed tip of the spear pierced the slime's body effortlessly.

The blue liquid spilled, revealing a small blue core within. Alex retrieved the monster core, measuring about a centimeter in diameter, possessing the same blue hue as the slime. He placed this newfound proof inside his pocket alongside the previous one.

With this successful hunt, Alex had unequivocally demonstrated that he had indeed transmigrated to another world—a realm teeming with magical creatures reminiscent of the fantasy stories and games from his home planet. The excitement of the discovery pulsed through him as he considered the possibilities that awaited him in this enchanting new reality.

Armed with the much-awaited proof of his otherworldly existence, Alex steeled himself for the challenges that lay ahead. The enchantment of this magical realm was coupled with its inherent dangers. Unlike a game where innumerable lives were at one's disposal, survival in this reality was paramount. Alex realized that to truly savor this magical encounter, he had to navigate its perils and emerge unscathed.

With a clear sense of purpose and a multitude of goals, both small and large, Alex, spear in hand, pressed on with his exploration. Each step forward represented not just a physical journey through the unknown but also a quest for understanding—why he had been transported to this otherworldly realm and what mysteries awaited him. The magical encounter had become more than a mere adventure; it was now a journey of survival and self-discovery.
