I Spent One Night with the Terminally Ill Daughter of the World’s Greatest Warrior

---

Through the healing process with Mo Yongseol, I clearly realized the potential my body possessed.

The realization of miracles.

If one sincerely desires, my bodily fluids will manifest it.

The Sword Saint concluded this even before I could fully grasp the phenomenon.

Thanks to that, I was able to clearly identify the changes occurring in my body.

If the other party earnestly wishes for something, there exists a power that makes it come true.

First, Mo Yongseol entered my bedroom at night.

She wanted to be treated for Absolute Meridian Sickness.

Second, with her Absolute Meridian Sickness treated.

She wished that I wouldn’t leave once her sickness was healed and hoped it wouldn’t be completely cured.

Third, Yu Giyeon.

With the complete healing of her Absolute Meridian Sickness, she wished her body, which had suffered from it for four years, to revert to the state of when she was 20 years old.

Fourth, Sword Mistress Geum Jeomri.

She desired youth and became the sword-honored Geum Serin.

And here, there is a woman who helped prove that hypothesis by using her own body.

“It seems that you really have to earnestly desire something for it to come true, Physician.”

Fifth, Mo Yongseol.

She said that once her Absolute Meridian Sickness was fully healed, she would immediately grant me everything I wished for, and thus, she entered the healing process, which led to her complete recovery.

“I don’t think I can just suddenly want to fly in the sky or become the world’s top heroine.”

“Right?”

Now, it wouldn’t be strange to call this body a miracle body.

However, I realized that even miracles have their limits, so first and foremost, one must sincerely wish for that miracle to occur.

“I wish a million gold pieces would suddenly pour down in front of me or that I could become a peerless master like Sword Saint Mo Yongcheon.”

“Unless it’s just wishing for an incurable illness to be cured, receiving the Extreme Yang Reversal treatment won’t have any effect.”

A fervent wish.

While I can’t recklessly set a standard for how intense that earnestness is for every person, it was clear that there should at least be some degree of willpower involved.

In the case of Mo Yongseol, she came to find me on the third floor of the Medical Hall at night with a mindset of wanting to at least do something she wished for as a woman before she died.

In the case of Sword Mistress, she was ready to risk her life by launching a strong attack toward the front gate of the most powerful family in the world.

In Yu Giyeon’s case, she was so desperate that she was willing to personally test Mo Yongseol’s initial treatment method—“Sleeping heals you.”

And furthermore—

“If one is so earnest to the extent of wanting more, even after already being cured.”

Now, beneath this Medical Hall, it feels like the leader of the Purple Sword Gate and his daughter are digging a trap as if concocting some scheme.

“Is it true, Sword Mistress?”

“Of course. The girl distinctly heard it with these two ears.”

The Sword Mistress, Geum Serin, pointed to her ears and below.

“The leader of the Purple Sword Gate, Yu Gwain, is trying to take Physician Seok to the Purple Sword Gate, all for his daughter.”

“Does Yu Giyeon still think I am being one-sidedly taken by Mo Yongseol?”

“She dreams of being the hero who saves Physician Seok from the wicked Mo Yongseol while forcefully treating her under the strong oppression of the Five Great Families.”

“What a madwoman… cough cough.”

Mo Yongseol cursed impulsively but quickly swallowed her words because none of it was untrue.

“To say such a thing in person, is she not insane? If we send her back to the Purple Sword Gate like this, she will absolutely lose her mind.”

I can proclaim it without hesitation.

Yu Giyeon is a lunatic.

The issue is that despite possessing such madness, she is ‘earnest.’

“This is a realm of possibility, but it’s probably clear. If Yu Giyeon thinks, ‘I must get stronger to rescue Physician Seok from Mo Yong Family,’ then a much stronger heroine will surely be born.”

“…Just like her martial arts drastically rising with the Reversal of Aging.”

The Sword Mistress lightly tapped her foot on the floor.

“Right now, at the very least, she’s in peak form. I can assure you of that.”

“If it’s fortunate that she’s not at the absolute peak, then perhaps that’s a blessing.”

“Why not at absolute peak? If she’s going to get stronger anyway, she should just say, ‘Make it so I can even defeat the Sword Saint.’”

Just as Mo Yongseol said.

“That might actually be possible, so it would be best to be cautious with your words from now on.”

“A good thought. If you consider the leader of the Purple Sword Gate, if he believes he is stronger than the Sword Saint, he would have that desire to grant his daughter’s wish.”

At the Sword Mistress’s words, Mo Yongseol bit her lower lip.

“If Yu Gwain were to… um…”

“Although we’re making various assumptions right now, I would kindly ask you not to speak of such terrible conjectures, young lady.”

“I’m speaking of blood. What kind of thoughts do you have right now?”

At my question, Mo Yongseol glared at me seriously.

“I’m the only one who can touch that, Physician.”

“Oh, in that sense?”

“Of course. Did you ever think to allow anyone else?”

“Not at all. Already, my heart belongs to you. How could I commit such a contradiction as to allow my body to be given to someone else? Even if what is leaving my body has already departed, I will do my utmost to ensure they cannot recklessly invade my body.”

“Physician…”

Mo Yongseol’s eyes softened as she buried her face in my arms.

Momentarily, the poison of the treatment period surged within Mo Yongseol, but it quickly subsided.

“I must get stronger. Whoever in the world targets you, I need to be able to protect you.”

Correction.

That poison directed itself elsewhere.

“If I become as strong as my father, then no one but me could ever try to take you, Physician?”

Mo Yongseol grasped my face.

“I’ll experiment right away.”

“Young lady, now is—”

Zoop!

“…Ahem.”

While my face was being forcibly held, I turned my eyes to the Sword Mistress and wrote in the air with my hands.

– Check inner energy.

I would love to transmit my will through telepathy like those high-level practitioners, but if I can’t, I have no choice but to write in the air.

“Huff…”

The Sword Mistress sighed deeply and stood behind Mo Yongseol.

“I’ll verify if it really works. Young lady, don’t be surprised even if my hands touch you.”

Zoop!

Mo Yongseol sat atop me in my chair and reached her hands back to my neck in response, while the Sword Mistress sat behind her, pressing her hands against Mo Yongseol’s back.

“Hmm…”

With a serious expression, the Sword Mistress felt Mo Yongseol’s pulse.

Unlike me, as a physician checking the blood vessels, the Sword Mistress was now gauging Mo Yongseol’s inner energy.

“Intern, how strong do you want to be?”

“Puhah. Hmm, how about like the Sword Mistress…?”

Mo Yongseol stated her desired standard and lunged back at me.

The Sword Mistress behind Mo Yongseol slightly furrowed her brows but continued to check the status of her inner energy without saying anything further.

“…Huh, I don’t think we can go any further.”

Mo Yongseol buried her face in my shoulder, and I glanced at the Sword Mistress over Mo Yongseol’s shoulder.

“How is it?”

“…It’s impressive.”

The Sword Mistress swallowed nervously.

“The positive aspect is that there is indeed a meaningful improvement in her inner energy.”

“Really?!”

“Yes, sister. But….”

The Sword Mistress reached out her hand toward the back of the rejoicing Mo Yongseol.

“Her Absolute Meridian Sickness was cured, and her Lower Dantian has opened up, correct? She has reached peak form.”

“Ahaha… thanks to Physician Seok, I’ve attained that peak…?”

“…The negative aspect is that the Yang energy obtained from Physician Seok is currently residing in her Lower Dantian, and it’s not enough to defeat the Sword Mistress.”

“Wait, really?”

Mo Yongseol was taken aback.

“That’s strange. I wished so earnestly…”

“There may be limits in terms of inner energy. Or perhaps, although one might think they have wished for it, something is still missing or off.”

“…Maybe, this is just the girl’s thought.”

The Sword Mistress pointed at me.

“It seems one can only rise to the next level when they achieve peak form, which means it’s likely tied to the Lower Dantian’s realm.”

“Lower Dantian… up to peak, you mean?”

“Yes. There are already two cases, aren’t there?”

Mo Yongseol and Yu Giyeon.

“The daughter of the number one person in the world and the daughter of the Purple Sword Gate leader, who is considered ordinary in the Martial World, have both reached their peaks. Perhaps even an ordinary woman without any connection to the Martial World might become a peak practitioner.”

“If she wishes to become a strong martial artist.”

“Yes. In other words…”

The Sword Mistress replied with a serious expression.

“As long as Physician Seok is present, he could elevate all members of the Haedong Sword Sect to peak female practitioners.”

“…….”

“And one more thing.”

The Sword Mistress grabbed Mo Yongseol’s shoulder.

“From there on, the growth rate will vary depending on how much Yang energy she receives from Physician Seok.”

“Excuse me?”

“I’m not saying this thoughtlessly, but….”

The Sword Mistress trembled as she spoke.

“…Do you know the saying ‘采阳补阴’ (Collecting Yang to Supplement Yin)?”

* * *

Late at night.

Having just returned from sending off the boss, Mo Yongsan had to meet a new guest immediately.

“Is this Yu Gwain, the leader of the Purple Sword Gate? What brings you here?”

“Lord.”

Yu Gwain clasped his hands and bowed to Mo Yongsan.

“I sincerely thank you for treating my daughter but, shamelessly, I would like to make one request.”

“A request, you say?”

Mo Yongsan slowly seated himself.

“What is it that you request of me, as a mere side branch of the Mo Yong Family, that brings you here so closely?”

Feeling the familiar and sharp sensation from outside, Mo Yongsan instead felt relieved and addressed Yu Gwain leisurely.

“The Purple Sword Gate formally seeks protection from the Mo Yong Family.”

“Formally…?”

“Yes. It could be becoming one of my retainers or my family’s servant.”

“…Why?”

Mo Yongsan held his throbbing head.

“What on earth?”

“…It truly embarrasses me to say this from the Mo Yong Family, but as soon as my daughter steps outside the Mo Yong Family, she will be targeted by various ‘color demons’ in the Central Plains.”

“Color demons?”

“Yes. …They will probably try to kidnap or abduct my daughter as soon as she returns to the Purple Sword Gate.”

Yu Gwain said, swallowing hard.

“While her Absolute Meridian Sickness was treated, the method was the prescription for Extreme Yang Reversal. The excess Yin energy was countered by Physician Seok’s tonic, creating a harmony with the Yang energy, allowing her Absolute Meridian Sickness to be resolved, right?”

“Indeed.”

Mo Yongsan nodded, having understood part of the truth but only concerning the outward appearance.

“In other words, the Yin energy residing in my daughter’s body has not completely vanished. So….”

“…Don’t tell me.”

Something flickered in Mo Yongsan’s mind.

“They will try to ‘Collect Yin to Supplement Yang’ using Yu Giyeon…?”

“Yes. So, I want to leave my daughter here. And….”

Yu Gwain exhaled heavily and lowered his head.

“I will select a few women to take care of my daughter and assist with the family business. This is the least I can do as this abducted father.”

Yu Gwain shed a tear.

* * *

“Surely this must be a lie. This is some nonsense aimed at inducing sympathy with false tears.”

The Sword Mistress stated without hesitation.

“They’ll attach the women from their sect or their maids to Yu Giyeon to help her reach peak form. Whatever it takes to secure the Extreme Yang Reversal. For that, they would probably resort to employing beauties.”

“…So, you mean.”

Mo Yongseol lifted one side of her mouth.

“They plan to use enchantresses from the Mo Yong Family to charm our Physician to obtain Extreme Yang Reversal, leading her to peak form?”

Collecting Yang to Supplement Yin.

The women suffering from Absolute Meridian Sickness aim to either supplement their Yin energy with the Yang energy from Extreme Yang Reversal or convert the Yang energy from the Extreme Yang Reversal into Yin energy to increase their inner strength.

“And this is just a hypothesis, but the women who increase their Yin energy through Collecting Yang to Supplement Yin will certainly undress for someone. For someone’s…’Collecting Yin to Supplement Yang.’”

“Ha…!”

“How ridiculous.”

I was so struck dumb that I couldn’t help but feel annoyed.

“Whoever came up with this idea, it really is a foolish plan.”

“…….”

“Why do you look at me like that? No, why do you look like that, Sword Mistress?”

For a moment, unable to believe my eyes, I almost slipped into using honorifics with the 17-year-old Sword Mistress.

“No, um.”

The Sword Mistress looked at me with a rancid expression.

“…From what I know, I can’t help but concern myself with the ‘background’ of Physician Seok.”

“……!!”

Mo Yongseol was suddenly shocked and grabbed me tightly.

“Our Physician has nothing to do with those fools!”

“…Young lady, calm down for a moment.”

I patted Mo Yongseol’s back and exchanged glances with the Sword Mistress.

“So, are ‘they’ backing up the Purple Sword Gate?”

“That’s correct. To be precise—”

[I’ll explain it.]

Wheeing.

Along with a vibrating sound, the blue sword entered the room.

[Are you planning to remain so close before I provide an explanation?]

“……Uh, well.”

[…Ha, enough already.]

The Sword Saint sighed.

He doesn’t even think about how the powerful sword communicates.

The Sword Saint is the greatest in the world and, judging from the Sword Mistress’s reaction, it seems to be a technique that only the Sword Saint can perform.

[To put it simply, just get to the conclusion.]

The Sword Saint’s sword pointed to the ground.

[Yu Giyeon has a fiancé, and he is here to treat her. Do you remember?]

“Yes, I’m aware.”

[That man is a pawn sent by the Heavenly Demon. Not a mere underling.]

“…….”

Could it be a ploy from the Demon Cult?

“Ah, father. That…”

Mo Yongseol looked flustered.

“The Demon Cult isn’t a group of fools, so would they resort to such crude schemes?”

[Indeed.]

The Sword Saint confirmed.

[It’s because they’re a bunch of fools who think such tactics will work that they’re finished.]

“…….”

[And it’s because those idiots, who can only think up such schemes, lead the group that the Demon Cult is bound to fail.]

Such a blunt criticism, yet.

“I can’t deny it.”

Having been captured as an orphan and witnessing the reality of the Demon Cult for years, I couldn’t help but fully agree with the Sword Saint’s words.

“So what should we do?”

[I have a plan.]

“…Are we going to kill them all?”

[Unless we want unnecessary bloodshed, we won’t kill them all.]

The sword and the Sword Saint looked at me.

Perhaps it’s because if someone were to die, it would shake my heart, or perhaps they’re worried about Mo Yongseol’s emotions.

[Seol Ah.]

“Yes, Father.”

[Let’s solve this with the methods of the Mo Yong Family.]

Upon the Sword Saint’s words, Mo Yongseol smiled slyly.

“I’ll get stronger and crush them all. They’ll never look at my man again.”

[Exactly. …That.]

The Sword Saint hesitated for a moment.

[Just like your mother did, and as I have done too.]

At first in an embarrassing manner, but soon with a proud voice he continued.

[Sword Mistress. I ask of you.]

“…….”

[Sword Mistress?]

“…….”

[Ha.]

More deeply than when talking about the Demon Cult, he sighed.

[I kindly ask this of you, Sword Mistress Geum Serin.]

“Leave it to me, Lord.”

…Perhaps dealing with the various martial factions and their influences in the Central Plains is even more challenging than facing the Demon Cult.
