Sitting on the edge of the old cot in the chilly twilight of the attic, Mina stared into space with a burning glint in her eyes.
Her balance-sheet-trained mind had just connected all the dots.
The local equivalent of Viagra in this world went by the evocative name of Vigor Elixir.
From what she could dredge up from the fragmented memories of the body's previous owner, brewing it required merely a competent Apprentice-rank mage who had mastered the fundamentals of alchemy.
Yet Mina furrowed her brow as the core reason surfaced in her mind - the reason the Inquisition and the empires had slapped the concoction with a ruthless, blanket ban.
It all came down to the Toadfolk.
They were foul, humanoid amphibians dwelling in damp subterranean caverns and stagnant caves.
They possessed an unbelievable, almost catastrophic reproductive rate and secreted dense, biologically active fluids that had fascinated the most desperate researchers for centuries.
And in local alchemy, an ancient, unyielding adage held sway:
“You are what you consume.”
Some two hundred and fifty years ago, an eccentric female alchemist on a research expedition had been captured by an entire horde of the creatures and dragged into the depths of their subterranean dens.
After four long months of rigorous field research, relentless observation, and... deeply personal hands-on experience, the woman miraculously made her way back to civilization.
She returned not only with a revolutionary pharmaceutical breakthrough, but with extraordinarily complicated feelings toward the Toadfolk.
Hatred?
Most likely. At least, that was her official testimony.
One way or another, she formulated the legendary Vigor Elixir, whose key active ingredient was derived directly from those cave-dwelling brutes.
Her invention became such an explosive market sensation that within barely a century, the Toadfolk population across the entire Empire had been poached nearly to extinction by hordes of trappers and greedy herbalists.
That was when the authorities stepped in.
The prevailing belief that a consumer absorbed the traits of the ingested reagents sparked a moral panic - there was widespread dread that the nobility and burghers would begin mutating en masse into croaking, wart-covered amphibians.
Consequently, the elixir was strictly outlawed.
Naturally, the prohibition had the exact opposite effect.
The potion instantly went underground, and on the black market its price skyrocketed year after year due to the catastrophic scarcity of wild Toadfolk.
“This might just be my shot...”
Mina whispered, a predatory glint flashing in her eyes.
She looked at the translucent azure panel hovering before her and smirked.
“After all, you’re tailor-made for this sort of improper filth, aren't you?”
Focusing her thoughts, she delved deep into the recipe catalog.
After a few seconds of browsing through the tabs, she found what she was looking for:
[Recipe: Classic Vigor Elixir.]
The price brought a wide grin to her face - a measly twenty copper coins.
She didn’t even need to head down to the alms box in the sacristy; the morning collection from the plate and donations after the Liturgy of the First Dawn more than covered it.
Without hesitation, Mina clicked purchase.
The coins vanished from her purse, and a detailed list of ingredients unfurled in mid-air:
[Recipe: Classic Vigor Elixir]
50 grams of Mist Mushrooms
50 grams of Blood Pepper
15 grams of Blue Root
150 grams of Mountain Basilisk Meat slices
350 milliliters of Pink Slime Nectar
2 liters of fresh water
300 milliliters of Toadfolk Semen
“Mist mushrooms... I have a whole drawer. Blood pepper is here, blue root as well. The basilisk strips are sitting in a brine crock, the slime nectar is on the shelf, water from the well... I have literally everything! Except...”
Her eyes traveled down to the final line, and her expression hardened by the second into a mask of boundless fury.
“You goddamn system!” she bellowed into the room, rattling the windowpanes.
“Those fucking Toadfolk are the exact reason this brew is illegal and worth a fortune! Where am I supposed to pull three hundred milliliters of cave-dwelling frogman spunk from in the middle of the night?! Am I supposed to march out to the wetlands with a bucket and ask them for a hand-job?!”
As if answering her rage, the interface flickered.
The lines of text shifted, and a new, golden-pink prompt materialized on the screen:
[Critical biological reagent deficit detected in the local environment.]
[Alternative alchemical pathway proposed: Vigor Elixir (Milky Version)]
50 grams of Blood Pepper
15 grams of Blue Root
150 grams of Mountain Basilisk Meat slices
350 milliliters of Pink Slime Nectar
2 liters of fresh water
300 milliliters of Mina’s Milk
Mina blinked, her jaw dropping nearly to the floorboards.
“Mina’s... Milk?” she choked out in utter stupefaction.
“What the fresh hell kind of ingredient is that?! Where on earth am I supposed to get milk named after myself?!”
The system didn’t make her wait.
Directly below, a promotional shop notification popped up:
[SPECIAL RESCUE PACKAGE FOR THE PRIESTESS]
Unlock Skill Bundle: [Milk Alchemy]
Cost: 5 Gold Coins + 300 Faith Points
Bundle Contents:
[Mina’s Milk]
[Dairy Cow Mina]
[Milk Alchemy]
[Vigor Elixir (Milky Version)]
Mina narrowed her eyes at the text with deep suspicion.
“Dairy Cow Mina?... Wait. Can you actually conjure a magical dairy cow for me?”
She scratched her temple, feeling a prick of revulsion.
“You really are bizarre... I just hope there isn’t some perverted catch lurking in the fine print. Then again... this is the only version of the Vigor Elixir I can actually brew with the herbs on hand.”
She sighed heavily, tabulating her resources.
She had three hundred Faith points in the bank - accumulated over the day from conducting liturgy, the repressed lusts of confessing parishioners, and potion sales.
But gold coins?
Officially, she had nothing but coppers in her purse.
Frowning, she frantically sifted through her predecessor’s memories.
Suddenly, a vivid image flashed in her mind: a musty corner of the attic, dust bunnies beneath the bed, and a loosened floor nail.
Mina dropped to her knees, crawling under the wooden bedframe.
Feeling along the floorboards, she found one with a slight give. Prying it up with her fingernails, she slid the board aside.
Resting in a hollow carved into the joist was a small, lead-reinforced casket.
With trembling fingers, she popped the latch.
Retrieving the gold, she sat back on the floorboards.
“Whatever. It’s a high-risk investment... but the return might just save my life,” she muttered grimly.
Gritting her teeth, she tapped the pulsing [Purchase Bundle] button in the air.
A soft, crystalline chime rang through the room.
[Deducted: 5 Gold Coins and 300 Faith Points.]
The five gold discs resting in her palm flared with a pale glow.
The metal turned translucent, dissolving into shimmering gold dust that vanished into thin air without a trace.
Immediately, a cascade of notifications showered down:
[Congratulations! Bundle Unlocked: Milk Alchemy]

The breath trapped in Mina’s lungs the moment she finished the final line.
Clutching her head with both hands, she buried her fingers into her hair:
“Jesus Christ... This system is completely depraved and broken! Instead of delivering a cow to the stables... it turned me into the fucking cow!”
Before she could even stand, a surging wave of dense, scalding heat erupted from deep within her chest.
Right before her eyes, her previously firm, shapely bust - a generous C-cup - began swelling, stretching taut, and ballooning at a dizzying, downright impossible pace.
The thin linen of her chemise stretched tight like a storm-blown sail.
Seams strained and groaned in protest, and two pearlescent buttons popped with a loud crack, pinging off the far wall.
“Wait... stop! Stop it!” Mina squeaked in panic, clutching at her breasts.
Her bust showed no intention of stopping, however.
They expanded with every passing second, engorging with incredible density and heft until they settled into a full, monumental, jaw-dropping E-cup.
Her center of gravity shifted so violently that Mina lost her balance entirely.
With a dull gasp, she toppled backward straight onto the mattress.
From the force of the fall, her newly acquired, colossal breasts bounced high, undulating like two massive, supple globes, knocking the wind clean out of her.
Splayed on her back, she stared down at the monumental spectacle in absolute, paralyzing shock.
“Fuck... I always wanted bigger tits... But never in my life did I think my wish would come true in such a twisted, fucked-up way!”
In sheer disbelief, she reached out with a trembling hand and lightly tapped the top of her left breast with the back of her fingers.
The flesh immediately jiggled, plush and resilient like a perfectly set milk pudding, shooting a searing jolt straight into her nerves.
And then the skill's secondary effect hit.
They hadn't just grown enormous - the nerve endings across her chest detonated with an unnatural, hypersensitive charge.
Under the fierce pressure of lactation, her nipples hardened into tight, rigid peaks in a fraction of a second, chafing against the frayed edges of the torn linen.
A jolt so electrifying shot through Mina’s sternum that she arched off the bed, a strangled, humiliating moan tearing from her lips:
“Fuck... why are they so damn sensitive?!”
Suddenly, she felt the fabric across her chest turn alarmingly warm and wet.
Mina yanked at the shredded remnants of her chemise, peeling them off entirely to bare herself from the waist up.
In the cool moonlight, the sight was breathtaking.
At the crests of her engorged, heavy breasts, shimmering, pearlescent droplets of thick, magical milk began welling steadily from her taut, rosy nipples.
Narrow rivulets traced down the lush swells, dripping straight across her stomach and onto the gleaming demonic brand below her navel.
Mina lay there, naked from the waist up, her left eye twitching erratically as she took in the scene.
“Well, isn’t that just lovely...” she grated through clenched teeth, her voice dripping with bottomless sarcasm.
“Just bloody fantastic. Guess I’m not a Daughter of Light anymore... From now on, I’m the Daughter of Plenty.”
