MARVEL-THE MULTIVERSE TRADER

Chapter 51: HEALING SERUM



Nova gestured toward one of the nearby couches.

"Alright — get your old man lying down over there. No sense talking while he's half-conscious."

Harry carefully helped Mr. Granger over to the couch, supporting the man's weight as Mrs. Granger hovered anxiously beside them, wringing her hands. The poor man groaned faintly, his face pale, a nasty bruise darkening along his temple.

"Careful," Mrs. Granger whispered, her voice tight with worry. "Please — careful."

Hermione knelt down at her father's side, brushing his hair back from his face, her brow furrowed deeply. She looked up at Harry, her face pale but determined.

"He's stable, I think," she murmured. "But he needs help now."

Nova strolled toward a modest-looking cupboard on the far wall. His hand reached inside — though in truth, he pulled the item from his system inventory, a smooth sleight of hand masked by the motion. From within, he withdrew a small, clear vial filled with a pale, crystalline-blue liquid that shimmered faintly in the dim lighting.

Hermione's sharp eyes immediately caught the glint of metal and the vial. She straightened up, the strain in her face tightening as suspicion and curiosity warred in her expression.

"What's that?" she asked, her voice tense, gaze flicking between the sleek, pen-like injector and Nova's calm face.

Harry edged closer, glancing between them uncertainly.

Nova held it up between two fingers, the pale glow of the lamp catching the polished surface.

"A healing serum," Nova said with effortless nonchalance, holding up the shimmering pale-blue liquid. "It'll heal and regenerate everything — internal injuries, shattered bones, cracked ribs, ruptured organs… even missing limbs."

The liquid inside glimmered like bottled starlight.

"Bloody hell," Harry muttered under his breath, eyes wide.

Nova continued smoothly, "It doesn't just mend like your Skele-Gro or basic healing charms. It triggers rapid cellular regeneration at the molecular level, forcing the body to rebuild what's broken. Fast, clean, no scarring, no lingering pain, no side effects and no reduced lifespan. In under a minute, it'll be as if the injury never existed."

That landed in the room like a dropped boulder.

Mrs. Granger sucked in a sharp breath, clutching her hands to her chest.

Harry blinked. "I've… I've never heard of a potion like that. Not even in the Restricted Section."

"Neither have I," Hermione said quietly, stepping forward, her brow furrowed in deep concentration.

Nova gave a low, humorless chuckle and shook his head. "Not a potion, kid."

"Then what is it?" Hermione asked, her voice edged with equal parts wariness and desperate hope.

"A serum," Nova replied, kneeling beside Mr. Granger. "Pure science. No spells, no charms, no runes, no potioneering. Just biology, chemistry, and physics working together the way nature designed them to — but pushed to an engineered extreme."

Hermione hesitated, visibly struggling with the statement. Her brow knit, lips parted, then closed again. She looked back at her mother, who nodded mutely, eyes glassy.

"But… how?" Hermione managed, shaking her head. "Aren't magic and science completely different things? Magic can do things science insists are impossible. Spells, charms, transfiguration — they defy the very laws of nature. They aren't governed by physics or biology, not the way we understand them."

She bit her lip, frustration flickering in her gaze. "You can't replicate what magic does with chemicals and machines. Can you?"

Nova grinned, sharp-edged, enjoying the challenge. He held the serum up again, letting its crystalline shimmer dance in the lamplight.

"That's where you're wrong, Granger," he said quietly, though confidence underpinned his calm tone. "Magic isn't some untouchable miracle. At its core, it's energy — like heat, light, or gravity. It's just a higher level of energy. You wave a wand, will something to happen, and what you're really doing is manipulating energy to alter matter. Science does the same thing — just without the Latin incantations."

He tilted his head, watching her carefully.

Harry frowned, stepping beside Hermione. "Wait… so magic's just… energy manipulation?"

"Exactly," Nova said, a gleam in his eye. "Transfiguration? You turn a pebble into a chair. By scientific law, that should be impossible unless you're adding energy or drawing mass from somewhere else. That's exactly what magic does. It isn't breaking the rules. It's working with a set you haven't charted yet."

Hermione was silent for a beat, visibly wrestling with the notion.

"Magic and science aren't two different fields," Nova went on, voice smooth. "It's just your current research level of science is very low, compared to magic."

Harry scratched the back of his head. "Er… so you mean… if science knew enough, it could do what magic does?"

"And more," Nova said simply. Afterall someone was able to control time and timeline using technology back in Marvel world.

He uncorked the vial, the liquid inside shifting like bottled starlight.

"Magic's just a form of higher tier natural energy," Nova continued. "The laws of physics still apply — magic just bends them."

Hermione crossed her arms tightly, but her eyes never left the vial. "Alright," she said softly, stubborn. "Then explain it. How does that—" she nodded toward the serum "—work without magic?"

Nova grinned. "Glad you asked."

He lifted the vial slightly. "This came from regenerative biology. Certain reptiles can regrow limbs, organs, even parts of their brain. We isolated the gene sequences and proteins responsible — particularly fibroblast growth factors, neural stem cell activators, and enhanced telomerase sequences — then stabilized them for human physiology. Using synthetic RNA scaffolding and self-limiting viral vectors, we built a compound to force human cells to activate those dormant pathways."

Hermione's face flickered with astonishment, like a doorway to a whole new world had cracked open before her, while Harry had three big comical question marks on his head. What RNA? Stem cell?..???

Harry's eyebrows knitted. "Er… I don't get half of that, but it sounds mental."

Mrs. Granger let out a soft gasp, pressing her hand to her mouth.

Nova continued, unruffled. "Took regenerative genome patterns from lizards and built a formula that triggers rapid, controlled tissue regrowth in humans. Accelerated mitotic rates, protein synthesis, axon reconnection for nerves — the whole package. A proprietary enzyme cocktail controls the cell cycle checkpoints to prevent oncogenic mutations, and the serum's nanostructure includes programmed shutdown triggers once baseline morphology is restored."

Mrs. Granger swallowed hard, finally finding her voice. "And… it's safe?"

Nova didn't hesitate. "As safe as anything gets," he replied evenly, holding her gaze. "No cancer risk, no uncontrolled cell growth. It uses targeted telomere extension without risking genomic instability, and every regenerative cycle is capped by programmed apoptosis markers to clean up excess or damaged cells once the injury's healed. No scarring. No side effects. No shortened lifespan. It fixes what's broken — and then it turns itself off."

The room fell silent again — thick, heavy, uncertain — the weight of impossible things made suddenly real.

Harry let out a low whistle. "Bloody hell."

"That's… incredible," Hermione said at last, voice hoarse, a mixture of awe and the smallest flicker of fear in her tone.

Nova gave them a small, crooked smile. "Yeah. Now… let's fix your dad, shall we?"

Nova knelt beside Mr. Granger, adjusting the injector with deft fingers. The pen-like device clicked once — a quiet, precise sound — and the tip of the vial slid neatly into a concealed chamber at the base.

"This will sting a little," he murmured — mostly for the room's benefit, since the man was still unconscious.

Hermione crouched beside him again, eyes wide and darting between Nova's hands and her father's bruised face. "Wait, you're injecting it now?"

Nova nodded once, calm as ever. "No time like the present."

With practiced ease, he pressed the injector against Mr. Granger's neck, just beneath the jawline. A soft hiss followed as the serum was delivered. The blue liquid shimmered faintly through the transparent chamber as it drained.

Then… silence.

Harry leaned forward unconsciously, holding his breath. Mrs. Granger's hands hovered just inches above her husband's chest, trembling.

For a moment, nothing happened.

Then the bruising on Mr. Granger's temple began to recede — slowly at first, like a reverse tide pulling color away. The dark blotch lightened, the swelling shrinking visibly under their gaze. The purpling faded into a pale yellow… then into healthy skin tone. The cut above his brow sealed shut in seconds, pink and whole without even a faint mark.

Hermione gasped audibly. "Oh my—"

And it wasn't just the surface. They could feel it — an energy pulsing beneath the skin, subtle and powerful. Mr. Granger's breathing grew deeper, smoother. The tension in his limbs eased. His pallor shifted from sickly to healthy in real-time.

Harry blinked. "You've gotta be joking…"

He stared as Mr. Granger's chest rose and fell evenly, and then — almost impossibly — the man stirred.

His eyelids fluttered.

"John?" Mrs. Granger's voice cracked, tears already forming in her eyes.

Mr. Granger blinked slowly, eyes unfocused. "Wh… what happened?"
