I Became the Final Boss’s Limited-time Teacher

The reason I started writing novels was because of my first love.

There was a girl sitting next to me whose dream was to become a ‘novelist,’ so I wrote to impress her.

But, alas, I was a talentless being. Not a single thing was done right—my writing, descriptions, settings…ugh.

In martial arts, the historical accuracy was a mess, medieval fantasy had guns appearing out of nowhere, and the game settings were so chaotic that readers blasted me with criticism.

‘…I didn’t expect it to come back to me like this.’

I sighed deeply while pinching my forehead. Over twenty years have passed since I started waking up every morning coughing up blood, but I still hadn’t adapted to it.

Right now, my body was that of a supporting character from my first martial arts web novel, [King of Diamond Fist].

‘To possess the body of Bing Yeon… in a world mixed with my own novels…’

I had fallen into such a bizarre world—a world like kimchi pizza and sweet and sour pork all combined together.

And on top of that, as a fool afflicted with the Severed Pulse Condition, Nine Pulse Meridians, living a ticking-time-bomb life.

If I had to point out the origin of this tragedy, a certain devoted reader was largely to blame.

– Author-nim, you can’t stop the serialization! I’ve read all three works; what will I have to read if they disappear too!

The one remaining reader who stopped me from announcing a serialization halt when my final web novel, [I Got Trapped in a Game], was stuck at 2 views. (The reason it had 2 views was that I was one of them.)

– If it comes to this, I have no choice but to show my ‘sincerity.’

Thus, I saw the reader’s comment, and in a flash of light from the monitor, I was dragged here.

Normally, the author would summon a reader into the story, but I was the one who got summoned.

When I opened my eyes, I found myself living as a low-ranking member of the Five Poison Sect in Yunnan Province.

In the novel, I was a randomly added supporting character just to explain the constitution of the Northern Sea Ice Palace.

Later, I was hastily killed with just a wave of the Heavenly Demon’s hand—a half-brother to the Northern Sea Ice Palace heroine.

Hence, my hair turned stark white, and my eye color was blue.

In martial arts novels, I would often appear as a breathtaking beauty, partly due to my noble bloodline and the fact I had a cool-dere (cool yet deredere) trait.

‘I probably shouldn’t have added the setting that emits more dark energy than that “Ice Emperor”. I should have made myself a normal person with a strong physique…’

The reason I was living in the Five Poison Sect instead of the Ice Palace was due to my superior constitution compared to the heroine I had set up.

Thanks to my looks, I could manage not to starve anywhere, but this damned dark energy constitution was reversing my blood flow.

Even though I chewed countless Elixirs claiming to cure my condition, my body wasn’t getting any better.

Even the divine healer from my novel said it would be a miracle if I lived until adulthood. It was like saying the sky is blue.

‘If you’re going to send me into another life, why not as a strong one like the Infinite Sword Emperor or Poison Dragon…?’

Despite being on my sickbed today, I struggled to catch my breath and barely managed to rise.

Clutching my heart, I had to cough up a bit of blood just to move, which felt utterly miserable. It’s true what they say; you don’t realize the worth of health and life until you lose it.

To cut the long story short, I survived into adulthood.

I didn’t give up on life despite my constitution and attempted to train my body to grow stronger.

Even though I coughed up blood several times a day, I never stopped my breath control exercises.

I sought out the strong figures from my novels, bowing my head and asking them to teach me.

Since three of my novels were mixed together, I went back and forth between the East and Western Region, trying to master swordsmanship, aura, mana, and martial arts.

At first, they often rejected me, saying, ‘Who the hell do you think you are, living a ticking time bomb life?’ But once they saw my effort and willpower, they eventually accepted me as their disciple.

I was that desperate. I wanted to survive that much.

If I learned anything to suppress the cold energy wrapping around my body, I could extend my life just a little bit.

Maybe due to my unceasing efforts, I survived the ambush from the Green Forest and didn’t die during the infamous Righteous and Evil War.

That wasn’t covered in the original. The name “Bing Yeon” was engraved into the history of all martial artists.

I gained the alias Ice Dragon, grew strong enough to establish a small sect, and was recognized by people.

Sure, everything was good except for the fact my body was close to kicking the bucket and that I couldn’t find the Final Bosses from my novel no matter what I did.

I aimed to find the Final Bosses in this strange world.

Originally, the Final Bosses I wrote possessed beliefs contrasting with the protagonist and led mostly wretched lives, becoming twisted beings.

If they were fictional, it wouldn’t matter, but this was reality. As the creator of this world, I had a reason to find them.

“Master, did you cough?”

“Uh, I just woke up.”

Then, I had saved a young girl from a crazy fanatic cult.

A fanatical religious group that tried to feed blood and human flesh to children through human sacrifice.

With the martial arts and mana I had learned until now, I obliterated the existence of that cult. No one should have to witness children suffering like that.

“Girl, I was worried since it seems Master can hardly get up…”

The girl with black hair looked at me with concerned eyes. Her eyes were slightly red and swollen, hinting that she had been crying.

From the reported sight of her washing the wet towel and blood-stained cloth, it seemed she had been taking care of me again today.

“Bi Wol, you really don’t have to go this far. Your little hands must be all swollen.”

“Don’t say such hurtful things. How could a disciple leave the side of their master?”

The girl sitting beside me was named Bi Wol.

She looked exactly like the name and description of the Heavenly Demon from my story.

‘Originally, the cult’s name was Heavenly Demon Divine Sect…’

Like a curse that puts countless insects in a jar, leaving only one alive.

They would use a little girl while making her drink blood and flesh, ensuring she couldn’t cure her hunger without spilling blood.

This was a hidden backstory of Bi Wol, the Heavenly Demon, which I couldn’t include in the original and only jotted down somewhere in my notebook.

‘It’s all my karma. It’s my responsibility to clean up this mess.’

The Heavenly Demon in my novels didn’t know how to satisfy her hunger without killing someone.

Blood and human flesh were the only ways to quench her thirst and alleviate her hunger.

The Heavenly Demon in my novels didn’t know how to sleep without killing someone.

The cult, Heavenly Demon Divine, tortured her, ensuring that she couldn’t sleep until someone died.

The Heavenly Demon in my novels didn’t know the warmth of a loving parent.

The most they did was sell her for a handful of rice—they were her parents.

Desperate people who would die if they couldn’t sell their child, struggling to lessen their burdens.

“I like being by Master’s side. How could a girl forget the warm embrace that saved her life?”

I saved Bi Wol with a sense of atonement, even knowing that I needed to become the Heavenly Demon for the plot to progress.

What reason is needed when it comes to an adult saving a child?

Even if it twists the story’s flow, it did not matter to me. I was the original creator after all.

“Master, you taught me everything I need to live. How to breathe and how to make my heart beat again.”

“If you say it that way, others might misunderstand…”

Since the moment I saved her from the Heavenly Demon Divine, Bi Wol became my disciple.

I taught her how to buy food, how to work, and provided her a proper place to stay.

I also took in all the children who had been under the Heavenly Demon Divine as disciples. With this, Bi Wol should not have to worry about being killed later.

“What’s wrong with misunderstandings? Among Master’s disciples, I’ll be the one most deserving of being called Master’s beloved disciple.”

“That’s not what I meant.”

Bi Wol, smiling cheekily while cleaning the blood from around my mouth. She often showed excessive affection toward me.

Their relationship as Master and disciple was more than what suited the eye, making even the surrounding people and disciples astonished.

She stayed by my side until I fell asleep and was always the first thing I saw upon waking.

One day, when I was secretly drinking at an inn, she dragged me away saying that sick people shouldn’t drink alcohol.

‘Is this due to the Heavenly Demon Star’s influence?’

I could not comprehend how she operated.

Crossing boundaries of normalcy as if she were not even human, I gave up thinking.

“Master, breakfast and bathwater are ready.”

“I told you, you don’t have to.”

“But the hostess isn’t here; someone has to do this role, right?”

Thump! Spitting out a mouthful of blood also seemed of no concern to Bi Wol as she cuddled up to me.

Even if I was treated this nicely, my condition didn’t show any sign of improvement, and I was bound to die soon.

‘I’m worried about what happens after I die… Will I revert to the Heavenly Demon? I smashed the Heavenly Demon Divine Sect to bits.’

I reflected on the things I had done.

I saved a little girl who was about to lead a miserable life, and I took in beggars and children as disciples, helping many unfortunate people.

The protagonists from the original [King of Diamond Fist] would not kill Bi Wol either, so it was time to prepare for what’s next.

“Master? The food is getting cold.”

“Oh, Bi Wol.”

I spoke to Bi Wol, whose eyes were wide open while looking at me.

“I plan to take in your sisters soon.”

I needed to save the Final Boss, Verdandi, from my second web novel, and the Final Boss, Azazel, from my last web novel as well.

I thought that was the reason I had fallen into this world.

“Your sister? Based on your gender specification and titles, I can’t help but think you’re not trying to take little girls or amputees as your disciples…?”

At that moment, Bi Wol’s red eyes narrowed. Her gaze was sharp, reminiscent of a snake, and made a calculating judgment.

“Girl, may I ask why you dare want to take a woman into the sect?”

“…Bi Wol, you and her might end up suffering a fate worse than before. Please show a good example as a senior disciple.”

“I refuse.”

Bi Wol articulated her words, each one heavy with emotion as she broke her eating spoon.

Clang! The head of the spoon clattered down to the ground.

“If Master intends to abandon me for a new girl, then please take me with you.”

Bi Wol’s hand trembled, her voice slightly damp. It was clear she was scared of being abandoned again.

To be honest, I worried about how Bi Wol, who was so dependent on me, would loathe the world once I died.

If I died, she’d claim she didn’t need this world and become the Heavenly Demon Star, I feared.

“Surely you haven’t forgotten our sect’s rules, Bi Wol.”

“…I remember deeply the rule of the Ice Dragon Blossom Heart. Never kill for no reason.”

“If you keep that promise, you may accompany me on this journey.”

I had actually planned to take her along from the start.

After all, the other final bosses were just as dangerous as Bi Wol.

A hero with overflowing justice who kills indiscriminately if they feel someone’s values don’t align, even if they are righteous.

A saint who lost the love she craved due to an unfortunate past, who made a contract with the demonic to regain it.

Even if I were to face them now, I might not be able to subdue them properly.

“Girl, will you promise me? To protect Master from those wicked wolves.”

She nodded vigorously, pleading with eyes as if asking for a head pat like a puppy.
