CLASS F’S MONSTER SON-IN-LAW

Chapter 1

The marble floor of the Silverpeak Battle Academy’s Grand Dining Hall reflected the mid-morning light with unforgiving clarity, highlighting every speck of dust. Alex Vex was on his knees, scrubbing the floor with a threadbare, gray rag that should have been discarded weeks ago.

His uniform was cheap, ill-fitting denim—the non-sanctioned attire for the lowest-paid, unranked maintenance staff. He was nineteen years old, and he was scrubbing away the muddy footprint of a twelve-year-old student who had just purchased his first elemental focus wand.

A soft, almost musical laugh drifted over from the high-backed velvet booths reserved for the Academy’s elite.

“Look at him. Did you know the Lin family actually pays him a stipend? It’s not much, but enough for rice and water, apparently,” whispered one voice, laced with disdain.

“He is Lin Mei’s husband, after all,” replied another, harsher voice. “The shame-shield. Who else would marry a man with a zero-mana core? They keep him around so the other powerful houses don’t constantly propose to Mei-jie. It’s disgusting. She deserves a Fire-rank prodigy.”

Alex felt the vibrations of their voices through the stone, but his expression was utterly neutral. His eyes, the color of gunmetal, focused only on the molecular structure of the dirt clinging to the polymer threads of his rag. Inefficient. He could clean this entire quadrant in 0.05 seconds if he could apply 700 newtons of pressure through the micro-pores of his right hand. But that would crack the marble. And cracking the marble would draw attention.

He was Subject 001. Efficiency was paramount.

His current directive: Maintain low-priority, anonymous maintenance protocol.

The current obstacle: Contemptuous human social structure.

He ignored the chatter, his spine remaining perfectly straight in the posture of passive submission the Lin family had trained him into. The family was a declining powerhouse among the city’s cultivation sects, and they had arranged his marriage to Lin Mei—their beautiful, cold, and immensely talented daughter—for two purposes: to house his "unusually sturdy body" and to serve as a public disgrace, lowering Mei's social value just enough to keep powerful rivals from demanding her hand.

Suddenly, a shadow fell over him, blocking the light.

“Vex.”

The voice was Eric’s. Eric, the arrogant vice-president of the Student Council, a twenty-year-old who specialized in mid-tier Fire Magic and flaunted his rank like a peacock. Alex knew Eric enjoyed finding him in these positions of servitude. It was a cheap thrill, like kicking a stray dog.

Alex slowly rose, meeting Eric’s gaze. Eric was flanked by two lackeys, both smirking.

“You missed a spot, janitor,” Eric sneered, pointing down at a minuscule, invisible smudge. “It’s a disgrace to the Academy’s cleanliness standards.”

Alex looked at the spot. He saw the slight discoloration from a recently spilled citrus drink—a highly acidic stain that required a specific alkaline compound to neutralize, not manual scrubbing.

Eric didn’t wait for a response. He wanted a demonstration. He raised his hand, gathering a small, harmless sphere of flickering orange flame—an Ignition Orb spell, the most basic form of offensive magic.

"Let me show you how a real student cleans," Eric mocked, his eyes shining with sadistic pleasure. "Magic is superior to muscle, Vex. You should learn your place."

He launched the Orb. It hit Alex squarely on the chest.

The small, contained burst of heat was designed to be painful and startling, enough to make Alex jump back, drop his rag, and maybe cry out, thus splattering the dirty mop water all over his face. It was meant to be pure humiliation.

Analysis of Impact: The Orb delivered approximately 1,500 degrees Celsius for 0.1 seconds.

Alex didn't move. He didn't gasp. He didn't even blink.

The Ignition Orb flared and died, leaving a scorch mark the size of a coin on the denim of his uniform—a uniform that wasn't designed to withstand anything more than mild detergent.

Eric's smile froze. The two lackeys behind him looked confused. The crowd in the dining hall, who had been watching for the expected spectacle, murmured softly. Alex simply stood there, immobile, a tiny wreath of smoke rising from his chest.

“W-what?” Eric stammered, confusion overriding his arrogance. He hadn't used a powerful spell, but it should have burned the man's skin, at least caused a visible spasm of pain.

Alex's analytical brain, the relic of a fallen, hyper-advanced civilization, was already processing the interaction.

Conclusion: Threat neutralized. Attacker lacks conviction and power. Lethal response is unnecessary and violates the current directive.

Eric, realizing the demonstration had failed, tried to save face. He cleared his throat loudly. “Pathetic. Your skin is too thick to even react, is it? Fine. Clean up your mess and don’t look at me again.” He spun around sharply and stomped away, his entourage scrambling to catch up.

As Eric turned his back, Alex’s right hand—which held the scrubbing rag—gave an almost imperceptible twitch.

In that millisecond, Alex's internal chronometer ran a simulation: [Target: Eric. Weakness: Carotid Artery (Right side). Action: Kinetic strike. Result: Immediate loss of consciousness. Follow-up: Systemic shock. Time to lethal: 1.2 seconds.]

The movement stopped before it completed 0.01% of the total action. The predatory urge—the highly efficient, muscle-memory response learned over a thousand combat cycles in a life Alex couldn't remember but his body still knew—retreated. Objective is anonymity. Killing a target for low-level provocation is inefficient data.

Only the reader, aware of Alex’s terrifying self-control, would know that Eric had just walked away from certain death, mistaking a predator for a pet.

Lin Mei finally emerged from the booth. She was breathtaking, dressed in the luminous silk robes of the Academy’s Elite Third Rank, but her beauty was eclipsed by her rigid, glacial expression.

She didn't look at Alex's face. She looked at the scorch mark on his chest.

“You’re lucky you didn’t burn the marble, Vex,” she said, her voice a low, perfect pitch that carried no warmth whatsoever. “You start classes tomorrow. Class F. The lowest enrollment f*e. If you cause trouble, Father will revoke your janitor privileges. You belong in the basement.”

She pulled a cheap, stamped piece of plastic from her robe—a Student ID. Instead of handing it to him, she let it fall from her perfectly manicured fingers. It clattered loudly on the floor he had just cleaned.

“Pick it up,” she ordered, then turned and walked away without waiting for him to move.

Alex looked down at the ID card. The contempt of the world condensed into one small, plastic rectangle.

But what he saw wasn’t a card. His ancient, military-grade internal scanner overlaid the visual: [Object ID: Student Identification Card. Security Protocol: Level 1 (Weak). Tracking Module: Present. Location: Dormitory 7, Basement Level.]

He reached down and picked it up. He felt the residual energy signature of Lin Mei’s touch. A strange flicker, almost undetectable, pulsed in his blood—a sensation he recognized as a dormant energy seal.

They haven't just married me for my body, he thought, the first spark of raw, conscious thought breaking through his efficiency protocol. They intend to harvest me.

He turned his gaze toward the exit, a look of chilling, calculating contempt washing over his face.

The only way to break the seal was to force the Lin family to attack him with stronger, more complex energy—something that might overload his dormant processing unit. And the best place to draw that kind of power was at the school they held so dear.

He had been content to wait. Now, he had a mission. He would not be harvesting the energy of the Academy. He would be harvesting the energy of the Lin family.

Alex Vex walked toward the Annex Building, wearing a janitor’s uniform, carrying a mop, and carrying a student ID that listed him as Level 0. He knew that by the end of the week, the entire Silverpeak Academy would be screaming his name, but not for the reason they expected. Because the moment he stepped through the Annex gates, the ancient, dormant military AI in his core finally decided to run a background diagnostic on the world's supposed "magic," and the result was far worse than he anticipated:

[Diagnostic Complete. Assessment: Current Civilisation Technology is Malfunctioning and Self-Destructive. Conclusion: Protocol 77—System Reset—Recommended. Warning: Activation will trigger Hostile Response from Global AI Gatekeepers.]
