The story begins with the protagonist, an adult consciousness reincarnated as an abandoned baby named Ars, waking up alone in a dangerous, fantastical forest. Initially plagued by extreme hunger, he quickly adapts, observing the world's unusual features like two suns and moons, and giant flaming birds, confirming its fantasy nature. A mysterious "system" voice grants him [Hunger Resistance] (MAX level), ensuring his survival, and reveals his status: impossibly high defense (38,000), all seven magic aptitudes, and divine blessings, marking him as uniquely powerful from birth.
Over the next year, Ars gains [Loneliness Resistance] and learns to walk. At age one, he acquires [Psychokinesis] while trying to get a "Ringa" fruit, confirming his perilous location in a deep, undeveloped forest. At two, seeking meat, he defeats a C-rank "Red-Eyed Battle Rabbit" using Psychokinesis, his immense defense rendering its attacks harmless. He levels up but collapses from MP exhaustion. Later, facing a pack of eight C+ rank "Wild Bears," he spontaneously gains [Qi Gong], a unique skill for powerful ranged attacks. He uses this to defeat the pack, leveling up to 28 and ending the Beginner's Guide, his stats soaring further.
Four years pass, and Ars, now six, has established a self-sufficient life in a cave, his combat prowess and stats (Level 89, Defense 173,000) making him formidable. While exploring, he encounters humans for the first time: a group of knights led by Keiless Raynard, a General and Count of the Rosen Kingdom. Ars, feigning innocence, claims to be an abandoned child. Keiless, however, perceives Ars's unnatural strength and magical potential, and, moved by his story, offers to adopt him. Ars accepts, transitioning from solitary survival to a loving family.
Ars quickly adapts to his new life in the Raynard mansion with his adoptive father Keiless, mother Mary (a former Chief Court Mage), and younger sister Mel. He rapidly masters various combat arts and swordsmanship taught by Keiless, impressing everyone with his talent. During a sparring session, Ars's powerful Qi-infused attack surprises Keiless, who expertly counters, demonstrating his own strength while the household staff are terrified by Ars's resilience.
A year later, at age seven, Keiless's old friend, Layon Triaden, a Lieutenant General and Frontier Count, visits seeking refuge. Layon's family was attacked, his wife killed, and children missing, victims of a political assassination plot by the Duke's faction. Ars, using his [Status View] and keen observation, deduces Layon's identity and the urgency of his secret visit, impressing Layon. Keiless vows to help Layon bring the culprits to justice.
Ars reveals his magic to Mary, who, overjoyed, tests his aptitude. The crystal glows with all seven colors, a legendary feat. Mary, now Ars's magic instructor, explains magic concepts. Ars, struggling with advanced spells, has a breakthrough while reading an adventurer's memoir: magic is about understanding "concepts." Applying this, he successfully casts a powerful [Flame Cannon] and then [Water Mastery] to extinguish the resulting fire. Layon soon departs as the culprit is apprehended. Ars, now aware of political dangers, vows to help Layon in the future. The maid Sarah reflects on Ars's extraordinary talents and certainty that he will become a hero. Ars's journey has transformed from a solitary struggle to a life of privilege, love, and immense potential within a powerful noble family, poised to become a formidable force.
