Exiled to his grandparents' countryside farm after being deemed a useless heir, Sieghart refuses to accept his designated fate as a family failure. He spends his infancy observing his grandparents' agricultural spells, realizing that magic in this world is limited by small mana pools and physical exhaustion. By studying their movements and expressions, he unlocks the emotional triggers required to manipulate the elements, beginning with a tiny black flame born of his deep-seated anger. He systematically awakens the four basic elements of fire, water, wind, and earth, raising his magic attribute and unlocking the foundational branch of black magic. When his grandparents discover his massive mana capacity, they begin teaching him the practical efficiency of agricultural magic, which he uses to revitalize the farm's crop yield. He continues his secret training in the woods, pushing his spells to their absolute limits and developing a devastating long-range fireball. Through rigorous experimentation, he also unlocks white magic by channeling his protective instincts inward, creating a defensive layer beneath his skin to shield his fragile body. His peaceful progression is suddenly interrupted when the regional border comes under attack by monstrous invaders, forcing his grandparents to prepare for defense. One night, Sieghart spots mysterious lights moving through the dark crops and decides to investigate the fields alone. He encounters five pig-headed monsters sneaking toward the farmhouse, forcing him to engage in his first genuine life-or-death struggle. Using sand to blind his targets and launching rapid fireballs, he systematically eliminates the intruders before they can threaten his family. He uses earth magic to glide their heavy corpses to a remote corner of the farm, incinerating the evidence with black fire and wind to hide his involvement. The next morning, a military messenger arrives to warn them of stragglers, completely unaware that the sleepy toddler eating porridge has already eliminated the threat, but the rising smoke from the distant border suggests a far greater conflict is rapidly approaching their peaceful sanctuary.

Seeking financial independence to purchase advanced books and materials, Sieghart convinces his grandfather to let him work at an old-fashioned enchantment shop in town. The shop is managed by Master Thorne, a grumpy runesmith who specializes in obsolete weapons and tools that require direct mana charging instead of modern mana stones. Sieghart undergoes a test, channeling his raw energy into an enchanted bow designed to create magical arrows, which normally exhausts ordinary workers after a few charges. His infinite mana easily bypasses the weapon's limitations, unlocking the arcane magic path and the mana transfusion skill while filling the bow's hidden secondary storage arrays. He goes on to charge a gale spear, a tremor axe, and an ember sword, earning ten silver coins and establishing a weekly arrangement where Thorne brings depleted weapons directly to the farm. This consistent practice allows Sieghart to raise his mentality parameter, improve his defensive protection spell, and study the intricate runes that govern physical enchantments. He begins to realize that combat mages are undervalued in this world because their spells are considered too slow compared to the instantaneous speed of Aura warriors. Determined to rewrite these limitations, Sieghart trains himself to cast multiple spells simultaneously, combining elements to create hot sand, steam, and pressurized water streams capable of cutting solid stone. His routine is shattered when a teenager delivers an emergency mobilization order from the regional command, conscripting both Edric and Sieghart to support the struggling border forces. Sieghart discovers that his father, Lord Alaric, authorized the summons after selling his son's magical labor to the military in advance for fifty gold coins. This betrayal hardens Sieghart's resolve to sever all ties with his noble family, promising to treat this forced deployment as the final repayment of his childhood debt before claiming his absolute independence, completely unaware of the terrifying scale of the conflict that awaits them at the edge of the kingdom.

Arriving at the eastern defensive camp, Sieghart and Edric find themselves surrounded by exhausted recruits, wounded soldiers, and a looming sense of impending defeat. The camp is under constant threat from the Firians, a hostile faction of warriors who can absorb environmental heat and convert it into physical strength and rapid regeneration. During the first evening clash, Sieghart remains near the supply tents, acting as a magical restorer to rapidly recharge the frost weapons and bows needed to counter the enemy's fire. He observes the limitations of the defenders' slow magic and the overwhelming speed of the Aura users, realizing he must adapt his own combat style to survive. The next day, Sieghart trains himself to manipulate elements on a scale of mass destruction, preparing to intervene directly when the Firians launch their second sunset assault. As the enemy advances behind waves of distorting heat, Sieghart summons an enormous sphere of water above the camp and hurls it across the battlefield, drenching the attackers and neutralizing their flames. The sudden cooling allows the defenders' ice weapons to freeze the enemies in place, turning the tide of the battle and earning Sieghart valuable black magic experience points. However, his massive intervention draws the attention of the Firian commander, a powerful warrior who launches a colossal fireball directly at Sieghart's position. Sieghart survives the devastating explosion by improvising a water barrier and adapting his defensive protection spell to absorb the heat, but the blast destroys his supply wagon and leaves him exposed. The Firian leader then launches a full-scale assault, using a massive pressure wave to shatter the defensive line and target Sieghart directly. Edric attempts to shield his grandson, but he is struck by a second fireball and left critically injured with severe burns. Driven by pure rage, Sieghart unleashes an endless barrage of dark fireballs, overloading the commander's heat-absorption capacity until the man's body ignites from within and disintegrates in a massive explosion, leaving the remaining enemy forces to retreat in absolute terror.

In the aftermath of the battle, Sieghart desperately channels his white magic into his dying grandfather, unlocking the healing branch and the first aid spell to repair Edric's charred flesh. He spends an entire day continuously transferring restorative energy, ignoring his own extreme mental exhaustion until his grandfather finally regains consciousness. Recognizing that his display of power has attracted dangerous attention from military officials and noble factions, Sieghart uses his father's name to secure an immediate discharge and returns to the farm. He spends the following weeks refining his magical arsenal, creating structured spells like water cannon, wind blade, and earth bullet to systematically increase his magic attribute. However, his peaceful routine is shattered when a series of coordinated explosions tears through the farmhouse in the middle of the night. A mysterious observer named Thorne's associate drags Sieghart from his burning room, but the primary blast originates directly beneath his grandparents' bedroom, killing them instantly. Sieghart uses his magic to extinguish the flames and painstakingly recovers their remains, using his first aid spell to repair their broken bodies before burying them beneath an old tree. The observer reveals that he was hired to watch Sieghart after rumors of his battlefield exploits spread to rival noble houses who fear his potential. Realizing that his grandparents were murdered to eliminate witnesses and suppress his growth, Sieghart summons dozens of dark fireballs, his grief transforming into a cold, absolute resolve. He refuses to return to his father's estate for protection, choosing instead to reject the constraints of his noble bloodline and forge his own path of vengeance. He prepares to leave the ruins of his home, determined to hunt down the assassins and the conspirators responsible for the tragedy, regardless of how powerful they are, setting his sights on the capital where the true answers remain hidden.
