Luke's journey begins with a massive public humiliation that quickly turns into a divine mandate. Summoned to the glorious temple of Valtharion, Luke is tested with the Awakening Crystal only to reveal zero talent, prompting explosive laughter from the dragon empress and deep clenching of fists from the human emperor. The surrounding nobles look down on him as a lowly lifeform, but their smug satisfaction is shattered when an ancient, majestic pressure descends upon the temple. The Saintess's eyes turn pure white as the Goddess of Light herself forces the five rulers to marry their daughters to Luke under threat of divine wrath. Dragged to the ceremony hall, Luke is wed to five beautiful princesses whose faces are hidden beneath bridal veils. As the priests look on with fanatical reverence and the other princes sneer in contempt, Luke drinks the holy water and feels five celestial chains connect directly to his heart. The system activates, but Luke is left alone in his room, wondering if he has been abandoned until the beautiful vampire princess Selene Nightveil enters. Driven by a shared sense of isolation, they consummate their marriage, triggering a massive ten-thousand-fold return that grants Luke the SSS-rank Titan Knight origin skill. Armed with this power, Luke accompanies Selene back to the temple, only for a silver-haired vampire noble named Lucien to publicly mock Luke and demand Selene's hand. Infuriated, Luke challenges Lucien to a duel of honor, ignoring the gasps of the crowd who expect the talentless hero to be slaughtered. But as the referee shouts start, Luke activates his Titan Knight skill, causing golden energy to surge through his veins and the black stone arena to shatter under his feet. He launches forward like a cannonball, his fists caving in Lucien's chest and sending him crashing through stone pillars. Yet, just as victory seems assured, Lucien unleashes his true Crimson Vampire aura, blasting Luke away with a bloody explosion that leaves the crowd mocking him once more. But from the rising dust, a strange metallic sound begins to echo as Luke prepares to unleash a forbidden form that could drive him completely insane.

Buried under the debris of the shattered arena, Luke hears the urgent warning of his system and decides to activate the dangerous third form of his Titan Knight skill. A primal roar shakes the training grounds as Luke transforms into a twelve-foot-tall giant with glowing golden eyes and a monstrous physique. Behind him, a massive set of black knight armor named Velzareth floats in the void, bound by twelve giant chains that rattle violently as the giant tries to pull them with brute force. Though the armor rejects him, Luke's raw physical power is now terrifying. He charges forward, shattering Lucien's crimson blood barrier and slamming his giant fist directly into the vampire's chest, breaking his ribs and treating him like a rag doll. In a savage display of primal fury, Luke rips Lucien's heart out barehanded and bites into it, laughing wildly as blood drips from his mouth. The spectators pale in horror, and the Bloodgrave family erupts with murderous intent, but before the situation can spiral into a bloodbath, the Dragon Princess Rhaenyra Crimsonscale steps forward. With overwhelming noble pressure and eyes of molten gold, she effortlessly catches Luke's wild punch with a single palm, releasing a terrifying ancient pressure that forces the giant to shrink back into his human form. Rhaenyra casually throws the unconscious Luke over her shoulder and departs with the other princesses, leaving the crowd frozen in shock. Safely aboard a massive floating airship, the five wives gather to discuss their unwanted connection to the unconscious hero. Rhaenyra and Elaria express their pride and desire to break the holy chains, while Naivara laments that her father will never accept an unworthy partner. Selene, knowing her family will hunt Luke if she stays, kisses his forehead and begs the human princess Aurielle to protect him. When Luke finally wakes up in a simple room, he discovers the system has rewarded him for shocking his wives, granting him gold, body tempering potions, and ten beautiful apprentice mages. As Luke recruits his new followers, he is summoned by his tired human wife Aurielle, only for a panicked messenger to arrive with news that a greedy noble has come to ruin them.

Luke follows Aurielle to meet Baron Cedric Thornvale, a corrupt noble demanding the immediate repayment of a six-hundred-gold-coin debt or the surrender of Aurielle's territory, the Blackstone Highlands. Cedric shamelessly suggests Aurielle become his wife to clear the debt, prompting Luke to unleash his golden aura in silent fury. Luke shocks everyone by tossing six heavy gold pouches onto the table, completely clearing the debt with his system rewards. Afterward, Luke and Aurielle tour the impoverished territory, witnessing the severe water and food crises caused by Cedric's upstream dam. Luke uses his newly acquired Aqua Spring Crystals to refill the dry wells, bringing clean water to the weeping villagers, and distributes fast-growing Mana Wheat Seeds to solve the famine. These acts of benevolence earn him the fanatical loyalty of the citizens, who cheer for Aurielle and her mysterious husband. However, as Luke returns to the mansion, he is ambushed by five experienced Iron Knights sent by the vice captain Roland Ashenford, who intends to castrate Luke and claim Aurielle. Luke fights bravely but is overwhelmed by their coordinated attacks until the system urges him to summon the Velzareth armor. Reciting ancient ritual words, Luke shatters the void, causing dark-blue energy to erupt as the matte black armor with glowing azure runes locks onto his body. Wielding the void sword Voidfang, Luke easily slaughters the assassins, but his victory is cut short when he returns to find the lord's estate burning. Roland has launched a full-scale rebellion with his family's army, surrounding Aurielle and the loyal Bronze Knight Osric. Just as Roland's forces prepare to crush them, Luke arrives and snaps his fingers, summoning the Blackstone Guardian Legion from his S-rank Founder's Package. One thousand soldiers, one hundred Iron Knights, ten Bronze Knights, and a Silver Knight Commander appear in a tide of steel, completely reversing the battle. Aurielle, pushed to her limits, unleashes her Shadow Sovereign origin skill, dragging Roland and his uncle into a terrifying twilight realm where they are erased from existence.

With the rebellion crushed and the territory stabilized, Luke focuses on strengthening his forces by bringing his loyal followers into the Time Chamber, where thirty days of training equal only one day in Valtharion. Supported by the dense energy of the Mana Well and the Healing Spring, Luke's maids and guards rapidly break through to the Iron Knight realm. Luke himself reaches the peak of the Body Tempering realm and officially condenses an Aether Seed in his dantian, entering the Iron Knight realm. To secure the trade routes and provide jobs for his citizens, Luke leads ten Bronze Knights to eliminate the Black Ridge Marauders, a brutal bandit group terrorizing local merchants. At the bandit camp, Luke witnesses the captive Sophia, daughter of a prominent merchant company, and decides to test his first Titan form. He recites the ancient ritual of the Myrkhal Titan, causing the sky to shatter as he transforms into a fifteen-foot-tall storm giant covered in dark metal armor and crackling with blue lightning. He summons three void doppelgangers that possess his full physical strength, easily slaughtering the bandits and rescuing the female hostages. Sophia is deeply charmed by Luke's majestic rescue and clings to him during the return journey, which triggers a massive wave of jealousy in Aurielle. Upon returning, Luke receives an official invitation from Count Magnus Duvall to attend his daughter's twentieth birthday celebration. Realizing they must navigate the dangerous political waters of the county, Luke and Aurielle travel to the banquet, where they encounter the other princesses and hostile nobles. During the event, a massive ambush by the demonic cult known as the Demon Whisper occurs, activating ten demonic pillars of light and trapping the guests. Luke is forced to unleash his storm giant form once again to defend his wives, but the battle escalates when a giant thirty-foot-tall demonic owl beast is awakened by the cult's blood sacrifices. Luke, Aurielle, and Naivara must combine their ultimate skills to survive the cataclysmic explosion that threatens to consume the entire secret realm.
