Re:Birth: A Slow Burn LitRPG Mage Regressor-Chapter 21. Professor Kim

"Meow."

"I thought you didn't want to have cats."

"I don't."

"Then why is there a cat drinking milk in our dorm?"

"It's a long story."

Adom sat on his bed, watching the small black cat lap delicately at the bowl of milk he'd scrounged earlier. It was surreal seeing such a dainty creature and knowing that just hours ago, it had been a massive midnight puma. The transformation still boggled his mind.

The cat - he wasn't even sure if he should still call it a puma - paused its drinking to look up at him with those startling blue eyes. In the warm light of the dorm room, they seemed to shimmer with an intelligence that made him distinctly uncomfortable.

Sam sat down on his bed too, nursing his scratched hand. He'd learned the hard way that their new guest had strong opinions about being petted without permission. "At least it's cute. I like cats. Let's keep it."

"Yeah," Adom said, watching the black cat meticulously clean its whiskers. "At least for now."

"So..." Sam looked at his roommate. "What are we naming it?"

"Haven't really thought about it."

"How about Asteroid Destroyer?"

"No."

"Apocalypse Bringer?"

"Absolutely not."

"Death's Shadow?"

The cat actually hissed.

"Maybe we should call it-"

"Please stop," Adom begged. "You're terrible with names."

"Hey. I named my father's familiar!"

"Sam."

"What's wrong with that?"

"Mighty Fox is not a proper name for a fox familiar."

"I liked it."

"That says more about you than anyone else."

Sam flopped back onto his bed with an exaggerated huff. "You and your cat have no sense of grandeur." He lay there for a few seconds before rolling onto his side. "So... are you going to make it your familiar?"

Adom looked at the black cat, which was now watching their exchange with what he could swear was amusement in those too-intelligent blue eyes. "No."

After much consideration, Adom had decided to bring the creature - puma, cat, or whatever it truly was - back to the dorm. The decision wasn't entirely logical, but it hadn't tried to maul him in the alley, which seemed like a point in its favor.

At first, he'd thought it might be a spirit, but those had a different feel to them - more ethereal, less... solid.

A shapeshifter, perhaps? But natural shapeshifters usually couldn't maintain forms this perfectly, and they tended to avoid cities.

A familiar without a mage? Possible, but unlikely - familiars didn't typically show this level of independence.

The more he observed its seamless transformations and those unnaturally intelligent blue eyes, the more one explanation kept rising to the top of his list: a curse.

Curses were tricky things in the magical world - not quite spells, not quite bindings, but something in between. They worked by imposing a twisted pattern onto someone or something's natural mana flow.

While normal spells were temporary transformations of mana, curses were more like permanent distortions, forcing someone's mana to flow in unnatural ways that created lasting effects.

The strength of a curse depended on how deeply it was woven into the target's mana.

Surface curses were relatively simple - things like bad luck or minor transformations. These sat on top of someone's natural mana flow, like a parasitic pattern. Deeper curses actually altered the fundamental structure of someone's mana, making them far more difficult to break.

What made this particular case interesting was the transformation aspect. Most cursed transformations were crude - turning someone into a toad or a rat. But this was different. The creature moved between forms with an unsettling grace, and those eyes... they held far too much awareness for a simple transformation curse.

This had to be old magic, the kind that went bone-deep and rewrote the very essence of someone's being. The kind that was very rare to study. And as a mage that stumbled upon a very rare case...

Adom knew that breaking it would require more than just dispelling the surface pattern - he'd need to understand the entire structure of the curse, layer by layer, and carefully unwind it without damaging the original mana pattern underneath.

If he even could. Some curses became so integrated with their target that removing them was like trying to separate two colors of paint after they'd been mixed.

But it made for a good challenge.

Adom looked at the cat, then at Sam, who was already burrowing under his covers. He probably should tell his friend that this tiny, milk-drinking ball of fur had been a massive, shadowy puma just hours ago.

"Sam..."

"Goodnight guys," Sam mumbled into his pillow, then rolled over with a sleepy yawn.

Adom watched the steady rise and fall of his roommate's breathing. "Hmm. Maybe another time."

The cat caught his eye and let out what sounded suspiciously like a snort of agreement.

"Come on," Adom said to the cat, patting a spot on his bed.

The cat looked at him, blinked once, very slowly, then deliberately curled up right where it was - perfectly centered on Sam's rug. Within seconds, it was making small sleeping noises, whiskers twitching.

Adom chuckled despite himself. Right. That's why he didn't want pet cats - their absolute refusal to acknowledge any authority but their own. Even a cursed one, potentially dangerous and definitely magical, still had that insufferable feline tendency to do exactly the opposite of what was asked of it.

"Suit yourself then," Adom said, finally getting to bed.

"COME ON, ADOM!" Hugo's voice boomed across the training hall. "YOU'RE ALMOST THERE!"

"He's actually doing it!" Diana shouted, jumping up and down at the track's edge.

"GO GO GO!" Phil and Kaius were practically vibrating with excitement.

"THIRTY SECONDS LEFT!" Vale called out, watching the timer.

"DON'T YOU DARE STOP!" Even Sam, who usually treated physical exercise like a personal insult, was screaming himself hoarse. "DON'T YOU DARE!"

Adom couldn't really hear them anymore. His world had narrowed down to the burning in his lungs and the steady thud of his feet against the track. Every breath felt like swallowing fire. His legs had stopped being legs about six minutes ago - they were just pain-filled appendages that somehow kept moving.

Adom barely registered being lifted off his feet. The entire club had rushed the track, hoisting him onto their shoulders like he'd just won some grand championship instead of just... not dying during cardio.

The author's tale has been misappropriated; report any instances of this story on Amazon.

"HE DID IT!" Hugo screamed.

"Up! Up! Up!" The club chanted, tossing him in the air. Through his exhaustion-addled brain, Adom noticed Sam grinning like an idiot, clapping harder than anyone.

"Now that," Sam shouted over the celebration, "was actually kind of awesome!"

Adom would have replied with something appropriately sarcastic, but he was too busy trying not to throw up on his celebrating clubmates.

Also, he couldn't feel his legs. Or most of his body, really.

[Iron Lungs skill integration beginning...]

[Estimated recovery time: 47 minutes]

[Recommendation: Water. Lots of water.]

"It was just a ten-minute run..." Damus's dry voice cut through the celebration from somewhere in the back of the room, where he was casually leaning against the wall.

The entire club turned to glare at him in perfect synchronization - even Sam, who normally avoided confrontation.

Hugo just grinned wider, still holding the almost unconscious Adom. "Everything's 'just' something until you actually try to do it."

Damus raised an eyebrow, but wisely chose not to comment further.

*****

Adom sat against the wall, legs stretched out, watching the blurry shapes of people training. His vision had gotten worse since losing his glasses - now he could barely make out anything beyond 157 inches. Just vague shapes moving around, their edges bleeding into each other. The cat sat next to him, back straight, looking thoroughly unimpressed with the whole affair.

A water bottle appeared in front of his face, blocking what little vision he had left.

Adom squinted, which only made Hugo laugh.

"You know," Hugo said, settling down next to him, "you actually look pretty good without the glasses. Very scholarly-warrior chic."

"Everyone's telling me that. But I look like I'm constantly judging everyone," Adom muttered, accepting the water bottle. The cat gave it a disdainful glance.

"Aren't you, though?"

"That's... fair."

Hugo's laugh boomed across the training hall, making several students miss their steps. "You should really get new ones though. Can't have you missing all the important form corrections I'm about to show Sam."

As if summoned by his name, Sam's yelp of surprise echoed from somewhere in the blur of motion that was the training area. The cat's ear twitched - the closest thing to interest it had shown all morning.

"I can see just fine," Adom lied, taking a sip of water.

"You've been staring at the storage closet for five minutes."

"...that was the sparring area."

"No, that's over there," Hugo pointed somewhere to the left. "You were literally having a staring contest with a door."

"Ah."

Note to get new glasses. Very soon.

The cat chose this moment to yawn deliberately, showing off an impressive array of teeth that seemed just a bit too sharp for comfort. Hugo glanced at it, his expression shifting ever so slightly.

"Your new friend doesn't seem very impressed with our training methods."

"The cat," Adom said, "has very high standards."

"Have you considered making it your familiar?" Hugo asked, watching the cat with curious eyes.

"I tried. It... declined the offer."

Hugo's laugh echoed through the hall again. "Very cat-like indeed."

Adom hesitated for a moment, then turned toward Hugo. "By the way..."

Over the past two weeks, Adom had been carefully planting seeds. A question here about advanced magical theory during water breaks. A casual mention there about helping younger students with their assignments. He'd even started organizing the equipment after training sessions without being asked.

The club was just a club - a place for training. But it was also where Hugo spent a good portion of his time when he wasn't assisting Professor Kim in his research. And that's what Adom needed - those moments between exercises, those casual conversations where he could show he was more than meets the eyes.

Never anything obvious. He couldn't afford to seem eager. Just a second-year student showing unexpected maturity and academic insight. The kind of thing that might come up naturally in conversation between a teaching assistant and his professor.

It was a delicate balance.

Too much interest in Professor Kim's work would mark him as just another fan. Too little would defeat the purpose entirely. So instead, Adom focused on becoming the type of student Professor Kim would want to meet. The type Hugo would mention in passing during their assistant meetings.

The worst part was the waiting. Every time Hugo praised his progress or nodded thoughtfully at one of his theoretical questions, Adom had to resist the urge to press further.

He couldn't rush this. After all, he was supposed to be focused on training, on improving himself. The fact that he happened to be exactly the kind of student Professor Kim might want as a future assistant? That had to seem coincidental.

Hugo, for his part, seemed genuinely intrigued by Adom's questions. He'd pause before answering, sometimes cocking his head slightly as he considered the depth behind what seemed like simple curiosity. It wasn't the polite attention he gave to most students - there was a sharpness to his focus when Adom touched on more complex theories.

A few times, he'd even stayed after training to continue their discussions, absently fixing stances and correcting forms while diving deeper into magical theory. It was during these moments that Adom caught glimpses of the assistant researcher beneath the jovial club president - someone who clearly spent hours in the lab, who understood magic at a level far beyond basic spellwork.

But Hugo never quite took the bait. He'd engage enthusiastically with Adom's ideas, challenge his assumptions, even praise his insights - but he kept the conversations firmly in the theoretical realm. If he suspected Adom's ulterior motives, he gave no sign of it. And if he ever mentioned these conversations to Professor Kim, Adom had no way of knowing.

Then again, maybe that was the point. Hugo hadn't gotten to be a sixth-year research assistant by being oblivious to people's intentions.

"By the way," Hugo said, adjusting the straps of his bag as they finished cleaning up.

Adom's hands stilled on the training mat he was folding. He kept his voice casual. "Hm?"

"You know I'm Professor Kim's assistant, right?"

"Yeah. Why?"

Hugo shouldered his bag. "I mentioned our conversation about micro magic to him the other day." He paused. "The professor said he'd like to meet you, if you're interested."

Adom carefully kept folding the mat, fighting to keep his expression neutral even as something warm unfurled in his chest. There we go.

"Oh?" he managed.

"Don't play too cool now," Hugo said, his usual grin returning. "I saw that almost-smile."

"What does he want to discuss?" Adom asked, placing the folded mat on the pile, carefully not meeting Hugo's eyes.

"Your theory about resonance patterns in enchantment arrays." Hugo was watching him now, that familiar sharp focus back in his gaze. "It's similar to something he's been working on in the lab. Actually..." He paused, and Adom could feel him choosing his next words. "It's not just similar. You approached it from a completely different angle, but you ended up at the same theoretical framework he's been developing."

Adom allowed himself a small smile. Weeks of careful suggestions had paid off - dropping bits of advanced theory disguised as innocent questions, presenting alternative approaches as if they were just interesting thought experiments. He'd known exactly which problems Professor Kim was tackling in some of his research, and had carefully guided Hugo toward those specific topics, making the connections seem natural, coincidental.

A second-year student wouldn't know the solutions, of course. But asking the right questions? Suggesting unconventional approaches? That was just showing promise. And now it had worked - he had his opening.

"When did you want me to meet him?"

"Right now, actually, if you're free. He's usually in the lab around this time," Hugo said, adjusting his glasses.

Adom made a show of considering it, as if he might have more pressing matters than meeting one of the academy's leading researchers. "Yeah, that works for me. We could head over together?"

"Great, let's go then," Hugo said, already heading for the door.

*****

The cat padded silently between them as they made their way through the academy's winding corridors, its tail held high like some sort of furry navigation system. It had rejected every name Sam had suggested over the past week - "Lord Whiskers" had earned a particularly withering glare.

As they approached the research wing, Hugo slowed his pace. "I should probably warn you," he said, rubbing the back of his neck. "The professor is... special."

"I know," Adom nodded. "His work on magical resonance theory is brilliant. The implications for enchantment stability alone—"

"No, that's not—" Hugo cut himself off, looking oddly uncomfortable. "I mean, yes, he's brilliant, but that's not what I'm talking about." He sighed, glancing down at the cat, which had stopped to clean its paw with deliberate disinterest. "You'll see for yourself. Just... look beyond the apparent. You might be surprised."

Adom felt a twinge of unease.

In his past life, Professor Kim had been a reclusive figure, known only through his groundbreaking papers and occasional presentations. The man himself had remained a mystery, always declining public appearances in favor of his research. Now, watching Hugo's strange hesitation, Adom wondered what exactly he'd gotten himself into.

The cat finished its grooming and looked up at them both, its expression somehow managing to convey that it found their conversation tedious. It flicked its tail once and continued down the hall, clearly expecting them to follow.

"Right," Hugo muttered. "This way." He paused. "And try not to stare. He really hates that."

Stare at what? Adom wanted to ask, but Hugo was already moving again, following the cat around a corner toward a heavy wooden door marked "Advanced Theoretical Research - Authorized Personnel Only."

Hugo approached the door and knocked - one-two, one-two-three, one-two - a rhythmic pattern that made Adom and the cat exchange glances. Before Adom could comment on the peculiar entry code, the door swung open on its own with a soft creak.

A wave of smells hit them: the sharp tang of magical reagents, the bitter undertone of spent tonic potions, the metallic note of enchanted equipment running hot. It wasn't unpleasant, exactly, but it had the distinct aroma of too many hours spent indoors with too little ventilation. The kind of smell that spoke of sleepless nights and forgotten meals.

The laboratory itself was dim, lit only by the soft blue glow of various magical instruments and the occasional spark from whatever experiment was running in the corner. Shadows played across walls lined with shelves of equipment and books, their shapes shifting as different devices pulsed with energy.

"Let's go in," Hugo said, stepping through the doorway. "Professor Kim, how are you doing today?"

The figure at the workbench didn't turn around or pause in whatever they were doing. Their hands moved in precise motions over what looked like a complex array of crystals and metal, either completely absorbed in the work or deliberately ignoring them.

Hugo sighed. "And there he goes again." He glanced at Adom with an apologetic shrug. "Sometimes he gets like this when he's working. Could be hours before he—"

The explosion wasn't particularly large, but it was bright enough to make them all flinch. Blue sparks scattered across the workbench as the professor cursed under his breath, frantically scribbling in a notebook.

"Fascinating reaction to the microscopic resonance, must account for the crystalline matrix's tendency to—"

"Professor," Adom said carefully, "I think your mustache is on fire."

"Professor Kim! Fire!" Hugo called out.

The professor spun around, eyes wide behind protective goggles. "Oh! Hugo! And a random boy! And a random cat! Fire?" His hands patted his coat. "Where? Oh, my mustache!"

He looked left, then right, then left again, before lunging toward a large aquarium filled with what appeared to be glowing fish. Without hesitation, he dunked his entire head into the water.

"What the f—" Adom started, but the professor was already pulling his head out, water and a few confused fish dropping from his now-extinguished mustache.

"Welcome to my laboratory!" Professor Kim beamed at them, pushing his goggles up onto his forehead. "I was just conducting a minor experiment. Completely routine explosion. Now, who might you be?"

"Professor," Hugo began, "this is Adom Sylla, the second year I—"

"Adom Sylla?!" Professor Kim's face lit up like one of his experimental arrays. He practically bounded across the laboratory, narrowly avoiding three different precarious-looking setups, water still dripping from his mustache. "The one who proposed the alternative approach to resonance patterns!"

He grabbed Adom's hand and shook it with enthusiasm that bordered on concerning. "How are you? Wonderful to finally meet you! Hugo's told me all about your theoretical framework. Brilliant perspective, absolutely brilliant. Have you considered the implications for multi-layered arrays? Of course you have, you must have, that's why you suggested the parallel configuration, isn't it?"

Adom stood there, his hand still being vigorously shaken, trying to process how he'd gone from watching a man dunk his head in an aquarium to being praised for theoretical magic in the span of thirty seconds. He managed a "Thank you, Professor" while attempting to subtly regain control of his arm.

"Oh! But you must see what I'm working on! Well, what just exploded, but the principle is sound!" Professor Kim finally released Adom's hand only to grab his sleeve instead, pulling him toward the workbench. "Hugo, bring that notebook, the blue one."

"This one?"

"No, the other blue one. The blue-blue one!"

As Professor Kim excitedly pulled him toward the still-smoking workbench, Adom's eyes darted between the scattered crystals, the charred metal components, and what appeared to be a small flame that was now burning upside down.

This... was not what he'd expected. All his careful planning, all those subtle conversations with Hugo, and now he was being dragged toward an active explosion site by a man whose mustache was leaving a trail of confused, glowing fish on the floor.

"See, the resonance matrix should have stabilized here," Professor Kim pointed at a blackened crystal, "but instead it created this fascinating chain reaction—" Another small pop made them both jump. "Oh, don't worry about that, completely normal. Probably."

He suddenly spotted one of the glowing fish flopping near his feet, just as the cat was crouching into pouncing position. "Oops, sorry Gege!" He scooped up the fish and dropped it back in the aquarium, barely breaking stride in his explanation. "Now, where was I? Ah yes, the chain reaction..."

Adom found himself torn between genuine academic fascination and basic self-preservation instincts. The theoretical framework was brilliant, he could see that even in its half-destroyed state, but he was also fairly certain that smoke wasn't supposed to be that color.

Behind them, he heard Hugo muttering something that sounded suspiciously like "At least nothing's on fire this time." This time?

Professor Kim was still talking about resonance patterns when Adom's eyes adjusted enough to the dim light to make out something in the corner. Behind stacks of books and equipment, partially covered by a heavy cloth, sat an unfinished framework. A prototype. Even in its crude state, the theoretical arrays were unmistakable.

So this was where it started, Adom thought. Dragon's Breath.
