Leo's first flawless, soulbound sword cannot be traded to the Registrar, but the system doubles his rewards anyway, boosting him to level three. He sets up a stall in the Ironhaven Bazaar and immediately breaks the game's economy. He sells a Rare Pattern-Welded Longsword to an incognito royal princess for thirty gold coins. Here, the functional worldbuilding shines: the system fails to calculate a withdrawal cap or transaction fee for his unclassified Mythic class. Recognizing the gold-to-dollar exchange rate has spiked to one gold to five hundred dollars, Leo converts twenty-eight gold coins to fourteen thousand dollars in cash. He pays off his bank foreclosure and his landlord, Mr. Hargrove, in a massive real-world reversal. When Paul's corporate suit returns to muscle him with a seventy-thirty split, Leo delivers a hilarious theatrical performance of a broken, destitute peasant before flatly rejecting him to eat cereal. The corporate investor leaves with an ominous threat that the real world is not safe, launching a lingering tension of physical danger that forces Leo back into the system to find the source of his power.

Driven by the persistent hidden quest, Memory of the First Fire, Leo ventures to the vitrified ruins west of Ironhaven and meets Shen, a Talisman Warrior holding the second key. Their collaboration is a masterclass in functional mechanics: Leo hammers the Cinder-Hide into a curved blade, and Shen carves the Guardian's Pact talisman into the spine. When Leo tempers the ink with his golden Eternal Flame, they trigger a rare upgrade, unlocking the Runic Inscription branch for Leo. This allows him to merge talisman work directly into his forging. Together, they descend into the five trials of the ancient forge, fighting spectral raiders and clearing the chambers. In the final chamber, Leo absorbs the hearth's dying flame, evolving his physique to the Iron-Forged Body, and reforges the broken ceremonial blade to seal the Inverse breach. He unlocks the Forge-Wielder's Crown, binding Shen as his first Knight. But as they step back into the forest, they are ambushed by a level-twelve rock-hided drake, forcing Leo to realize that his newly gained crown functions require him to rapidly complete his class advancement in the capital city of Graystone.

Reaching Graystone City, Leo attempts his class advancement, but his Mythic rank glitches the hall's testing crystal, dragging him into a high-difficulty trial in Asgard with a mere one point seven percent survival rate. He is immediately confronted by Captain Freya, whose level-one-hundred-plus guards drag him into a courtyard where she shatters his ribs with a spear blow. Surviving only through his Iron-Forged Body trait, Leo enters the Divine Forging Trial to earn an audience with Odin and access to the broken Mjölnir. Using his new S+ Talisman Forging talent, Leo enters the Mental Inscription Space to comprehend all forty-seven runes on the ancient stele, designing a revolutionary six-layer neural network of cognitive runes: Mnemos, Genesis, Logos, Experience, Curiosity, and Harmony. In the final round, he purifies nine legendary materials, including Starfall Iron and Adamantine, to ninety-nine point nine nine percent purity. He executes the unrecorded Rune-First Approach, carving the cognitive network before melting and fusing the metals. He hammers the Transcendent Epic-grade Starfall Hammer, earning the title of Divine Rune Blacksmith of Asgard and unlocking the Soul Forge branch, only to find himself locked in Asgard until he can repair the god's broken weapon.
