Hidden Route Discovered!

A grand swell of music rose as the ending credits began their slow climb up the screen.

White text scrolled over black — a roll call of every character I had conquered.

Yu Jin-hwa: 100%

Gyo Yeon-mae: 100%

Princess Jeongwan: 100%

Ung Seo-won: 100%

"Holy fucking shit...! I finally cleared it all."

My name is Jeong Ha-un.

I had just watched the ending of the notorious eroge Wurim Yeonga: Manhwagyeong.

And not just any ending — after dozens of playthroughs and guides, I had hunted down every last garbage-tier character and hit a full 100% completion rate.

Wurim Yeonga: Manhwagyeong was what people called a "shit-god game."

A vast, captivating world. Countless heroines tailored to every taste imaginable. Dozens of women, each with branching routes that shifted depending on your choices and playthrough. Hundreds of character-specific cutscenes alone.

You'd drop your pants, get sucked into the story and end up crying — then wipe ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠your tears just in time for some absurdly hot cutscene to make you bust all over again.

And yet the "shit" stuck to its name for a reason: the difficulty and the traps were completely unhinged.

The most infamous of them all was the early-game encounter with Oh Jeong-gwang the Lust Demon.

In an eroge, what does it mean to learn a Lust Demon's martial arts?

Normally you'd expect to pick up some lecherous technique and go around railing every female martial artist in the jianghu. Not in this game.

Early on, Oh Jeong-gwang approaches the protagonist and offers to teach him martial arts if he'll come along.

Choose Follow Oh Jeong-gwang, and it's over that same day.

You become a disciple of the Joyous Erotic Sect and learn its single-lineage art. The name is Joyous Erotic Demonic Art — but it's actually a virginity cultivation technique. Lose your virginity and you die. About a million years removed from becoming any kind of lust demon.

After that, every path leads to a pathetic death: you die fleeing, or you meet a woman, fail to resist temptation, and die. Stick to the training obediently and the game just shows you sitting in lotus position meditating all day.

A lonely death ending, basically.

The choice itself was one giant trap.

And Oh Jeong-gwang kept showing up whenever you'd almost forgotten him, trying to sweet-talk the protagonist into becoming his disciple. You could never follow him — not at any point. The correct move was to kill him the moment you got the chance.

Leave him alone and he'd find some other disciple, turn him into a monstrous Erotic Demon God, and NTR every single heroine you'd spent the whole game conquering.

Fuck, that one gave me some serious trauma.

The Erotic Demon God was not a boss you were meant to beat.

Every single stat was overwhelming. Martial skill, physical ability, stamina, looks... even dick size crushed the protagonist. All you could do was sit there and watch yourself get NTR'd, powerless.

Some gamers got so obsessed with those stats that they went hunting for a guide, wondering if following Oh Jeong-gwang might actually let you become the Erotic Demon God.

Like I hadn't already tried that myself.

For half a year I ran multi-clients every single day, meditating under Oh Jeong-gwang and ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠grinding internal energy. The result? A grand total of +0.5 internal energy.

This was not a route you were meant to clear.

See? Look at that.

100% completion ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠without ever touching the Erotic Demon God route.

At the very end of the credit scroll, golden, luminous letters bloomed across the screen.

100% Completion Achieved.

Hell yeah. This was what I'd spent three years after discharge grinding for...!

"Huh?"

But in that instant, the screen crackled with static — and the completion rate flipped to 99.9%.

Then a new choice appeared in blood-red text.

The Erotic Demon God route?!

No fucking way. Is this real?

I clicked it like a man possessed.

And there he was — that face I'd grown sick of seeing. Short, bald Oh Jeong-gwang the Lust Demon, delivering his usual line.

"I see in you a boundless talent for lust. Will you follow me and learn the secret arts of the Joyous Erotic Sect?"

<1. Follow Oh Jeong-gwang>

<2. Follow Oh Jeong-gwang>

<3. Follow Oh Jeong-gwang>

What the fuck. The only option is Follow Oh Jeong-gwang.

So this is what a hidden route looks like, huh?

The moment I hovered the cursor, all three choices lit up at once. Meaning it didn't matter which one I picked.

Heart pounding, I clicked.

With the spirit of a pioneer charting a route no one had ever reached.

Fwoooosh—!

And I was sucked straight into the screen.

"Son of a biiitch!"

The method for clearing the hidden Erotic Demon God route was to get isekai'd into the game and actually cultivate the erotic art for real.

And I had to spend a full thirty years doing nothing but accumulating internal energy while locked into a virginity technique.

"This is a fucking scam...!"

There was no way out.

Run before learning the art? You die to bandits or wild beasts on the road.

Run after learning it? You fail to resist temptation, have sex, and die.

Even masturbating drained your life force.

Every route that wasn't obedient martial training ended in a grotesque death. I'd tried them all. I knew better than anyone.

"Guhhh....! My thirty years...."

That was how I spent them. Even after being pulled into an eroge world, I never left the deep mountains. Thirty years of celibacy, martial training, and an ugly master.

Somewhere along the way, training together, I'd even grown attached to the old man.

"I said it was a scam, damn it."

"......"

But the master sitting before me — Oh Jeong-gwang — no longer answered.

His body had withered to a dry old tree. Only a faint smile remained on his lips.

Through the Transmission of Internal Energy, he had poured every last drop of the power he'd accumulated into me — and then slipped into eternal ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠rest.

Oh Jeong-gwang looked profoundly at peace.

"A Lust Demon, they called you. An erotic art, they called it — and every single sect leader across seventeen generations was a virgin. What kind of bullshit martial art even is this?"

I'd learned the truth while receiving the art directly from Oh Jeong-gwang inside the game. A secret of the Joyous Erotic Demonic Art that the game itself had never revealed.

Gather nine Gaps of pure virgin yang energy through the virginity technique, undergo rebirth, and you could achieve the Erotic Demon God.

But a lifetime of the art's basic breathing method only ever yielded half a Gap of internal energy.

So the sect leaders of the Joyous Erotic Sect had, across seventeen generations, carefully passed their energy down through Transmission of Internal Energy — stacking it up to 8.5 Gaps.

The internal energy of seventeen virgins.

Plus the half Gap I'd accumulated over thirty years.

Nine Gaps total. The Erotic Demon God, complete!

"It wasn't a scaaam!!!! You son of a biiitch!"

That's right.

The "fuck" I was screaming now wasn't a fuck of despair.

It was the fuck of triumph — of joy — after thirty years looping back to the final ending route!

"Accept my bow! Master! Ancestors! Every previous sect leader! I have gratefully received your virginity!"

Even if it was only the history of a game world — the internal energy my master had given me existed for real in my dantian.

"Master is dead. He's gone. But in my dantian, in my virginity, you all live on as one!"

If I was going to thrust, I'd thrust all the way to heaven!

Who did they think I was?

I am the Erotic Demon God!!

"Hup!"

I dropped straight into lotus position and began the rebirth.

With nine Gaps of internal energy, I circulated the Great Heavenly Cycle of the Joyous Erotic Demonic Art I had spent so long mastering.

Yang energy at its absolute peak began to tear through my body, and that power started reconstructing me from the inside out.

Crrrk— crack!

Bones shifted. Muscles swelled. Organs and joints found new places. The smell of burning flesh filled the air.

Gaaaaah!

Agony beyond description crashed over me.

But I had to endure it. I'd lasted thirty years — what was this compared to that?

I clenched my jaw and held on. Bit down so hard I could feel blood seeping from my gums.

Nnnngh! Hold on! Once I become the real Erotic Demon God...!

The Erotic Demon God's unmatched looks from the game. Monstrous stamina and infinite virility. If I could have all of that, it would be a straight-up cheat key.

And with that power in the hands of someone who already knew every heroine's conquest route...!

Just you wait, Sword Queen Yu Jin-hwa. Blood Plum Fairy Gyo Yeon-mae! Every last one of you, beneath my feet...!

Tssssss! Crrrk!

I endured and endured — and at last the pain receded, replaced by a rush of exhilaration.

Power flooded every inch of my body.

So this is the Erotic Demon God...!

I opened my eyes and stood. My line of sight sat a full handspan higher than before.

I looked down at myself.

A magnificent body of dense, sculpted muscle — exactly as I knew it. And nestled at my groin, a single dark-crimson dragon.

I did it. I finally did it! I've been reborn!

I was just starting to wonder where to put that dark-crimson dragon to work when a screen I'd completely forgotten appeared before my eyes.

Game text from Wurim Yeonga: Manhwagyeong — something I hadn't seen once in thirty years.

Ah? Aaaah?

Hey. You bastard.

What about the heroines I conquered?

Sword Queen Yu Jin-hwa? The Blood Plum Fairy!?

My beautiful eroge harem life...!

No — you son of a biiitch!!!

A familiar ceiling.

"Fuck."

I'd endured thirty years, completed the Erotic Demon God, and was finally ready to enjoy myself properly — and now, suddenly, the real world.

I woke up back in my shitty one-room apartment.

"Don't tell me… it was all a dream?"

What if the thirty years I'd survived and the agony of rebirth had all been a dream? What if I'd just fallen asleep grinding the game all night and hallucinated the whole thing...!?

Panicking, I checked my body first.

Fortunately, the mirror confirmed it — my face and body were still those of the Erotic Demon God.

Eyes deep and still enough to entrance anyone who met them. A high, proud bridge of a nose. A sharp yet masculine jawline. A hundred and ninety centimeters of height, broad shoulders, dense muscle, and that heavy dragon hanging between my legs.

The body of the Erotic Demon God, earned through pure ordeal, intact.

"Thank god……!"

At least it wasn't one of those "ah, it was all a dream" endings. Small mercies. Besides, what era is this? Pull a plot twist like that and the writer would be out of a job.

"Wait — then?"

Among the messages I'd seen right before crossing over was Erotic Demon Eye — Awakened.

Come to think of it, text was floating above my head in the mirror.

Fuck. My internal energy is zero?
