I Spent a Night with the Terminally ill Daughter of the World’s Greatest Master

An abandoned orphan.
An Evil Sect assassin.
More than these, my identity is closer to being a “physician.”
Partly because my master was “Evil Physician White Face,” but mainly because the skill I learned to survive was medicine.
-A physician must think logically and systematically, eliminating possibilities to derive the correct answer. You must diagnose symptoms and find treatment methods.
That was the mindset my master taught me as a physician.
Not just laying someone down and placing a wet towel on their head when they have a fever, but finding the one correct answer through a thought process based on my knowledge and experience—that was the foundation of my life.
In that sense, until just before the current situation occurred.
I could make various proposals to the father and daughter of the Mo Yong family.
As prescriptions are diverse, I could present numerous possibilities regarding the current situation.
Now it’s meaningless to mention those possibilities.
Physician Seok Mu Wol spent the night with the Mo Yong family’s precious daughter, the terminally ill daughter of the world’s greatest master, Mo Yong Seol, and her meridian blockage was cured.
Because this was announced in a large banquet hall attended by the Nine Schools and One Faction, the Five Great Families, and even people from the imperial palace.
About this situation, I naturally worried.
“The meridian blockage is cured?! Impossible! That’s an incurable disease! How many people have died from meridian blockage until now?!”
Denial. I worried about the reaction of those thrown into confusion when common sense was suddenly overturned.
I understand.
That was my first thought too.
“We can’t deny she’s cured, but cured after spending one night? Hah, that can’t be. Surely the Medical Dragon found some method. An incurable disease can’t be cured through the union of yin and yang.”
“He must have created an extraordinary medicine. More excellent than Shaolin’s Great Return Pill… a miracle drug that can cure any disease!”
Doubt. Though slightly different from denial, I worried about the reaction of those who couldn’t believe the Mo Yong family’s official announcement.
I understand.
I too wanted to believe it was my master’s medicinal pills that worked.
“The meridian blockage is cured…? Is the cause because Mo Yong young lady is the daughter of the world’s greatest master Sword Star, or is it because of Medical Dragon Physician Seok Mu Wol?”
Analysis. I worried about reactions that speculated on “how” the meridian blockage was cured, even amid the confusion.
I understand.
Mo Yong Seol isn’t the only meridian blockage patient, and there are many still suffering from it.
I thought people who would deny, cast doubt, and analyze would certainly appear.
But if there are those who worry me more than these people.
“Listen, Sword Star!!”
Those who sparkle with hope in their eyes.
“Tell us the truth! Please!!”
“Calm yourself, Tang Family Head.”
“How can I be calm now?! You’re saying meridian blockage is cured!!”
First among them, the head of the Sichuan Tang family who traveled across the Central Plains from Sichuan to Liaodong—[Poison King] Tang Si Hyuk and others like him.
“If your daughter is cured, then my daughter can be cured too!!”
Families of meridian blockage patients.
“Please tell me! What method did you use?! I believe that the Sword Star wouldn’t use his daughter to hide the cure for meridian blockage!”
“…Brother Tang. You know me. Am I the kind of person who would use such tricks?”
At the Sword Star’s words, several people nodded briefly.
“Does that make sense! Curing meridian blockage by sharing a blanket?! Ah, that’s it, right?! Huh?! Holding hands during the night to transfer innate true energy, or creating some special internal energy cultivation method?! That’s it, right?! Huh?!”
Desperation fills the Poison King’s eyes.
The normally cold and rational Poison King, called “Venomous Snake” because his temperament is like a snake, is now rambling incoherently.
He has conflicting feelings simultaneously, wanting to both affirm and deny.
If Mo Yong Seol was truly cured thanks to spending the night with me.
And if that method is not any other manipulation but truly due to the “union of yin and yang.”
“Could it be that my daughter would also be cured if she spent the night with the Medical Dragon…? Huh? Is that it…?!”
He has hope, but as a father, the method twists his judgment.
“…….”
The Sword Star remains silent.
Without denial, he simply nods silently.
“Hah, hahh….”
“Sword Star.”
Thud.
“May this Alliance Chief speak for a moment?”
Stepping forward, the Martial Arts Alliance Chief, Supreme Elder, came forward.
“Everyone is confused now, and it’s clear that without resolving this confusion, not only the Mo Yong family but the entire martial world will fall into chaos. So, let’s stop the banquet and—”
“Stop, the banquet?”
The Sword Star took one step forward.
Thud!
Several people staggered.
As if the earth’s pulling force had grown stronger, the air gained weight, pressing down from the head and making the body heavier.

“Since Mo Yong held the banquet, the decision to continue or stop it belongs to Mo Yong.”
The Sword Star extends his hand to the side.
The blue sword energy in his hand begins to emit light, and the Sword Star scans the audience with flashing blue eyes.
“Today’s banquet will be a celebration of my daughter’s cure and a pledge ceremony declaring the engagement of my daughter and Physician Seok Mu Wol. Already… they have exchanged vows directly with their lips.”
Again, I had many concerns.
The issue of my Evil Sect origin.
The cure for meridian blockage itself.
The world’s greatest beauty whom everyone desired, but who wasn’t considered for a “strategic marriage” because she was expected to die.
I thought many people would target Mo Yong Seol, or me, in the future.
And the biggest problem.
-Kill Mo Yong Seol.
The Demon King’s order.
-Kill Mo Yong Cheon’s daughter in the most miserable way, make the Sword Star shed tears of blood and feel pain as if he’s lost the world. That is your reason for living.
Hidden poisons who don’t follow orders are killed by evil people sent by the Demon King.
Just like my master died, assassinated by an assassin sent from the Evil Sect.
However.
What use are such worries?
“I only hope that my daughter will no longer shed tears from pain. Whether it’s physical or emotional.”
The Nine Schools and One Faction, the Five Great Families, the imperial palace, the Evil Sect, the Demon King.
“No one can oppress Mo Yong. Even if there are circumstances.”

There is a greater threat than all of those “death threats” combined.
“As long as this Mo Yong Cheon is alive with eyes open, anyone who mistreats or dishonors a member of the Mo Yong family will face my sword.”
Flash.
When a blue light flashed behind Mo Yong Cheon, several blue lights began to sparkle behind him.
“Seven Star Sword…!”
Seven swords made of sword energy.
They were sparkling behind Mo Yong Cheon—more precisely, protecting me and Mo Yong Seol like Dharma Protectors.
“Sword Control Technique…!”
Floating in the air.
“I will cut down anyone who disrupts the banquet with these swords.”
The world’s greatest master.
In some eras, the second greatest might hold their own against the greatest, but.
In the current martial world of this generation, Mo Yong Cheon is truly like “heaven.”
The “supreme” that no one can reach.
‘He’s strong enough to control seven energy swords individually with Sword Control Technique—who would dare challenge Mo Yong Cheon with force?’
My master said:
-The Demon King was the strongest among all the leaders of the Sun Moon Holy Cult. If not for the Sword Star, the Central Plains would have been ruled by the Sun Moon Holy Cult. …Because of the Sword Star, they had to bow their heads, calling themselves the Evil Sect rather than the Holy Cult.
From the beginning, everyone here could have been killed by the Demon King.
-Even if the entire Central Plains had joined forces, they couldn’t have defeated the Demon King at that time. The Sword Star Mo Yong Cheon defeated that Demon King alone without shedding a drop of blood. The world’s greatest master… no, perhaps the greatest of all time—meaning the strongest martial artist throughout martial arts history.
Such a person is not killing me but protecting me.
‘Let the Demon King or whoever come.’
The moment those outward-facing swords turn toward me will be just a single moment.
“Miss Mo Yong.”
I grabbed Mo Yong Seol’s waist.
“I will ensure tears never flow from your eyes.”
As long as I don’t make Mo Yong Seol cry, the Sword Star’s sword won’t target me.
“…What should I do?”
Mo Yong Seol’s eyes are already welling up with tears.
“I’ll cry tears of happiness every day.”
Ah.
Is this woman trying to assassinate me after all?
Or is she trying to assassinate her father?

Either way.
She was so beautiful, smiling brightly at me with tears in her eyes, that for a long time I couldn’t see or hear anything around me.
All my senses were focused solely on Mo Yong Seol.

The banquet ended.
-You may all withdraw for today. I will not tolerate any disturbance. If my daughter’s meridian blockage relapses because of any commotion, my sword will not forgive it.
Though Mo Yong Cheon had told the Martial Arts Alliance Chief he would continue the banquet, that was only to pressure them into letting the Mo Yong family control the situation.
Thud, thud.
Mo Yong Seol and I quietly followed Mo Yong Cheon.
“F-Family Head…! Eek…!”
Everyone we encountered on our path moved aside.
Not only the family retainers we met while passing through the estate but also the servants.
“B-Brother!”
If anyone dared to be brave, it was Mo Yong Cheon’s younger brother and Mo Yong Seol’s uncle—
“San. We’ll talk later. Withdraw for now.”

Mo Yong San.
But Mo Yong Cheon immediately ordered him to leave.
“B-Brother! No, Family Head! What on earth is…!”
Even family members didn’t know.
About Mo Yong Seol’s cure.
“I rushed here because I heard you collapsed, but what is all this confusion…!”
“In half an hour, the Martial Arts Alliance Chief, the Divine Monk, and the Divine Fairy of Emei will return to the main gate as representatives. Guide them to the reception room.”
“……Yes.”
Mo Yong San bowed his head at Mo Yong Cheon’s instruction.
“But, is it really true? That she was cured in one night?”
“…….”
“Ah, I understand. Y-your brother will follow your instructions.”
After dismissing Mo Yong San, we walked deep into the Mo Yong family estate for quite some time before the surroundings became quiet.
“Mo Yong Seol, and Physician Seok Mu Wol.”
The Sword Star stopped abruptly in place.
“The world will seek out both of you. Especially you, Physician Seok, you probably already have some idea.”
“Yes, Family Head.”
“The fact that you behaved as you did means you are prepared.”
“That is correct.”
The water is already spilled.
From the moment I confirmed that when yin and yang united, Mo Yong Seol’s blood vessels were unblocked and the symptoms of meridian blockage disappeared, I made up my mind.
“Stay in the safest place in the family compound for the time being. In the innermost estate.”
“F-Father. That place is…?”
“The separate pavilion where your mother and I lived together.”
“Ah… w-well then. Um.”
Mo Yong Seol cautiously approaches the Sword Star and grabs his collar.
“Well, you said the meridian blockage is cured because of ‘that’.”
“…Yes.”
“T-then… in that house, in that room, you know.”
It seems.
“…Can I continue the meridian blockage treatment with the physician?”
“What?”
Is she trying to assassinate her father too?
“W-well. Maybe because some time has passed…. I feel a slight chill, you could say… Eek?!”
Mo Yong Cheon instantly grabbed Mo Yong Seol’s wrist.
After staying still for quite some time, with a face that had received a great shock—
“Physician Seok.”
“Yes, Family Head.”
“Check her pulse.”
He extended Mo Yong Seol’s wrist to me.
“……!”
The moment I placed my hand, I sensed it.

“This is no joking matter.”
It wasn’t a complete “cure.” Confirmed.
“Um, physician?”
“Physician Seok.”
“Yes, Family Head.”
Mo Yong Cheon gives me a hand signal, hidden from Mo Yong Seol’s view.

“From now on, you are to go with my daughter and….”
Grind.

“Immediately investigate whether there is a correlation between the union of yin and yang and the improvement of meridian blockage. Immediately.”
“Ah, Dad?! T-that’s not what I meant, I didn’t want to do this and that with the physician in your and Mom’s nest…!”
“Seol.”
Mo Yong Cheon placed his hand on the flustered Mo Yong Seol’s shoulder.
“If you don’t clearly establish that correlation, other women will try to ‘verify the theory.'”
“!!”
A lie to deceive Mo Yong Seol, but also a plausible justification.
“They will try to receive treatment from Physician Seok.”
Mo Yong Seol’s body stiffened completely.
Without even realizing that the chill she mentioned was real.
“Didn’t you see Poison King Tang Si Hyuk? If it wasn’t me, Physician Seok might have been kidnapped by the Poison King and dragged to Sichuan by now.”
“…I see.”
“So you must find out somehow.”
The thesis.
Is the union of yin and yang truly the cure for meridian blockage?
If it truly cures through the union of yin and yang, is it because the meridian blockage patient is the daughter of the world’s greatest master?
Or is it a miracle that ‘only’ Physician Seok Mu Wol can perform?
I don’t know about myself, but for Mo Yong Cheon, who wants to present himself as “a father who disapproves of the physician who has a relationship with his daughter,” the most ideal inference is one.

“That the improvement of meridian blockage was merely a coincidence and miracle. That it has no connection whatsoever to the union of yin and yang.”
The collapse of a fundamental theory that makes it meaningless to consider additional theories derived from the thesis.
That the union of yin and yang is unrelated to the treatment of meridian blockage.
“Understand?”
“…Yes!!”
Mo Yong Seol responded with an energetic voice.
“I’ll go to the bedroom with the physician right now! Let’s go, physician!!”
Mo Yong Seol grabbed my wrist and ran, and I was dragged along with her.
“…Physician.”
As I was being dragged away, the Sword Star called out to me.
“Yes, Family Head.”
“Honestly, I’d prefer if there was no connection, as if we deceived Seol.”
To be honest, I’d prefer if there was no connection too.
‘He’s not in his right mind.’
Reason and emotion, martial artist’s common sense and the world’s greatest master’s intuition about the phenomenon are fighting fiercely.
Honestly, as he said to me, he would like to judge it as merely coincidence and miracle, that the meridian blockage would have been cured even without me.
“What do you think? As a physician, as a man, tell me. …Is there no connection?”
“As a physician, as a man, and to not shame my deceased master, I will tell you only the truth.”
But I know.
“There is a connection.”
“Is that so.”
The Sword Star closes his eyes.
“Indeed, so it is….”
‘I’m sorry, Father.’
Having directly treated her, I know well.
At “what time” the blood vessels become unblocked.
What the decisive trigger was for the improvement of symptoms after the blood vessels were unblocked.
And why, albeit very temporarily, yin energy began to gather around the blood vessels.
We had sex. She was cured.
I said it clearly from the beginning.
And didn’t he himself clearly answer my diagnosis?
-Thanks to you taking my daughter’s virginity, her blood vessels have normalized?
“Then.”
Mo Yong Cheon pointed ahead.
“I entrust my daughter’s continued treatment to you.”
The separate pavilion filled with memories of himself and Mo Yong Seol’s mother, the woman he loved.
“…Wait.”
As I was about to approach Mo Yong Seol, who was waving her hand in front of the pavilion, Mo Yong Cheon grabbed me.
“There’s one theoretical blind spot that just occurred to me.”
“Yes, Family Head.”
“…Must it be done inside? If it’s about infusing yang energy, wouldn’t raising the body’s heat be sufficient?”
As expected of the world’s greatest master.
“Isn’t acupuncture about inserting needles… to resolve issues? Right? Hm?”
Despite not being directly involved, despite not witnessing it firsthand, he’s noticed the core of the meridian blockage treatment process just from circumstantial evidence.
“I’ll try that approach.”
“…What?”
“Well.”
I answered the Sword Star with clasped hands.
“I’ve never tried it outside before.”
