After awakening as a seemingly useless E-1 ranker with no public skills, Jimin must immediately face his long-time tormentor, the arrogant earth-armor user Kang Dae-ho, who challenges him to a public duel on the very first day of combat class to humiliate him. With the cynical veteran instructor Ryu Seong-ho watching to test his resolve and the entire student body shouting mockery from the sidelines, Jimin steps into the arena with nothing but a basic training spear and two throwing blades hidden in his hands. He immediately realizes that his low physical stats cannot match Dae-ho's level-three brute strength, forcing him to rely entirely on his wits and his newly created Telekinesis. As the duel begins, Jimin intentionally drops one of his blades, distracting Dae-ho and creating a split-second opening to launch a relentless flurry of spear thrusts that keeps the bully on the defensive. When Dae-ho attempts to overpower him with a devastating heavy slash, Jimin utilizes his telekinetic grip to drive the dropped blades directly into his opponent's thigh and backside, causing the bully to scream in agony. The battle escalates to a fever pitch when Dae-ho counters with a brutal punch to Jimin's stomach that drains half his health, but Jimin refuses to back down, drawing on his reserves to reinforce his spear with invisible psychic force. In the final climax, as Dae-ho charges forward with an earth-shattering finishing strike, Jimin activates a newly edited Dash skill to vanish into a blurry afterimage, appearing at his opponent's flank and using telekinesis to trip him with his own spear. The sheer momentum sends Dae-ho flying face-first out of the arena boundaries, securing a shocking victory that leaves the mocking crowd in absolute, breathless silence. This triumph marks his first step toward dominance, but it also paints a massive target on his back as powerful enemies begin to notice his anomalous growth.

Desperate for funds to support his rapid growth and purchase high-quality gear, Jimin registers at the Appraiser Federation and unlocks a secret identity as the masked appraiser known as the Night Monarch. By upgrading his Appraisal skill to level ten, he gains the unprecedented ability to analyze high-tier D-rank equipment, a feat previously considered impossible for a novice E-ranker. He rents a stall at the bustling Yongsan Appraiser Center, offering both high-speed appraisals and a unique repair service that restores equipment durability on the spot for a fraction of the cost of professional blacksmiths. This combination of rare utility skills turns his stall into an overnight sensation among local Rifters, generating millions of won in profit and allowing him to purchase top-tier weapons like the twin Needle Stingers and the Spiral Lance of Wrath. However, his rapid financial success and mysterious identity attract the greedy eyes of rogue hunters, culminating in a deadly ambush in a dark alley by a psychotic archer wielding a silver revolver. Jimin is forced to drop his helpless facade, utilizing his newly acquired skills like Weight Distortion and Poison to turn the environment into a lethal trap and execute his assailant in self-defense. This bloody encounter forces Jimin to realize the brutal reality of the Rifter world, prompting him to create defensive skills like Pain Regulation and Regenerative Healing to prepare for the inevitable shadows creeping toward him. He meticulously cleanses the crime scene using a newly created Purification spell to erase every trace of blood and mana before the authorities can arrive, realizing that his survival depends on keeping his dual identity absolutely secret. As he walks away from the blood-stained alley with millions of won in hand, he knows he has crossed a line of no return, transitioning from a mere student into a ruthless survivor who will stop at nothing to protect his path to the top.

As the school transitions into practical combat training, Jimin's party is deployed to an E-rank Field Rift in Seongbuk district, a gloomy forest crawling with aggressive goblin hordes and hidden pitfalls. To maximize his experience gains and hide his true capabilities from his classmates, Jimin convinces his party to let him operate solo in the depths of the forest under the cover of his newly created Stealth and Spatial Awareness skills. Moving like an invisible shadow, he systematically slaughters dozens of goblin scouts and shamans, using his newly acquired Serrated Bloody Chakram and the Spiral Lance of Wrath to execute swift, silent kills. His rapid solo grind allows him to level up to E-rank level eight, but his focus quickly shifts back to his party when he senses their exhaustion through a tracking mark he left on Yuna. Rejoining his teammates just outside the Boss's lair, Jimin inspires them to launch a coordinated assault against the massive Goblin Chief, coordinating their attacks to overcome the monster's heavy defenses. During the chaotic climax, Jimin activates his newly created Moment of the Skillmaster to accelerate his cognitive speed, perceiving the battlefield in slow motion as he deflects incoming arrows and launches his lance with devastating force. The spinning lancehead drills directly through the Goblin Chief's skull, securing a spectacular victory that earns the party massive rewards and cements their status as the top rookies in the academy. This triumph not only proves their exceptional growth to the watching instructors but also unlocks a massive pool of Life Points that Jimin immediately invests in creating his most anticipated support skill, the Intelligent System Assistant named Mimi. With Mimi now integrated into his consciousness to manage his resource consumption and analyze battlefield data, Jimin prepares to face the final evaluation, unaware that a massive conspiracy is about to plunge the entire city into chaos.

The narrative escalates from localized school rivalries into a high-stakes national conspiracy as Jimin is suddenly ambushed on his way home by a mysterious black van. Two highly trained kidnappers attempt to subdue him using a powerful hypnosis artifact, but the attack is neutralized by his newly acquired Crown of the Mentalist, forcing Jimin into a desperate struggle for survival. He lures the attackers into a secluded alley, utilizing his full array of combat skills including Overtime, Weight Distortion, and his newly created Interrogation technique to overpower the high-level warrior Park Ba-reum. However, when Jimin attempts to force Ba-reum to reveal his employer's identity, an ominous purple energy erupts from the captive's body, causing him to violently explode into vapor to protect the organization's secrets. This horrifying self-destruct mechanism reveals the existence of the Umbral Shadow, a fanatical criminal syndicate led by the dying S-ranker Maxime Vox and the corrupt guild leader Baek Sang-hoon, who are artificially creating Rifts across Seoul to harvest lifeforce. As the government raises its surveillance levels and prepares for an unprecedented monster wave at the northern border, Jimin realizes that his peaceful civilian life is over and that he must accelerate his growth to survive the approaching storm. He stands at the precipice of a global conflict, armed with his unique Skillmaster system and a burning determination to uncover the truth behind his parents' tragic deaths. With the final evaluation just days away and the city's top guilds preparing for full mobilization, Jimin must leverage every resource at his disposal, refining his stealth and perception skills to navigate a battlefield where allies and enemies are indistinguishable. The stage is set for a massive clash of powers, and Jimin's journey from a weak E-1 orphan to a key player in a national conspiracy is about to reach its thrilling climax.
