Jin Cheon-hee moved to another building within the Qing Song branch of the Baekrin Medical Hall.
"I saved the Sect Leader. This alone will change a lot of the future I know. Will it be alright?"
Jin Cheon-hee's greatest weapon was emotion.
Information about the future.
The Sect Leader survived, and his disciple, Seol Gyeon, ascended to the position of the next Sect Leader.
The butterfly effect was certain to change many things.
But no matter how many times he thought about it, the answer remained the same.
"Yes. In the end, I will save the life before me again."
He couldn't help but feel that being a doctor was a truly pitiful profession.
His body moved before he could even think about the calculations.
There was no time to consider anything other than saving the lives of the sick.
"Yes. That's why I was able to see such a wonderful scene that I never even imagined."
This time, he succeeded.
The Elder would continue to use his martial arts, and his disciple would not fall into demonic qi and would be able to move forward.
Thinking of the two bickering, his heart warmed.
It was the sight of people returning to their daily lives.
"Yes. Even if I go back to the past, I will save them again."
The answer didn't change.
Jin Cheon-hee moved his steps to the farthest corner beyond the courtyard.
Running a medical hall meant being entangled in countless grudges and favors within the martial world.
It wasn't uncommon for two martial artists, sworn enemies, to stab each other and be brought in at the same time.
Even though the medical hall was a place where weapons were forbidden, the hearts of people were unpredictable, and even without weapons, martial artists themselves were human weapons.
So, from the beginning, they made sure to place the wards as far apart as possible and separate the routes to avoid any encounters.
The structure was more complicated than it looked.
Even veteran doctors with years of experience sometimes got lost, and in doing so, they occasionally discovered hidden secret wards.
Especially since this wasn't just any medical hall, but the Baekrin Medical Hall.
The Zhuge family was renowned for their mechanisms and formations.
The main hall was one thing, but even the local branches were personally designed by Zhuge Lin.
Jin Cheon-hee circled around the backyard a few times before finally arriving at his destination.
A small annex.
The arrangement of the trees was so exquisite that the annex couldn't be seen from other angles.
It was a place for patients who required confidentiality.
As Jin Cheon-hee approached the door, a killing intent brushed past him.
Soon, the door opened.
"You're here?"
It was Wang Gak-yeon.
She had been standing guard and recognized Jin Cheon-hee, relaxing her vigilance.
"Yeah, I'm here. And thank you."
"You always just say thank you," Wang Gak-yeon said, making Jin Cheon-hee scratch his head.
"I don't have anything else to say."
"You still haven't paid for the Baekrin Divine Pill, you fool. If you had, you'd have made me work even harder."
The Baekrin Divine Pill.
He had threatened her, saying if she didn't take it, he'd give it to Hwang-gu.
At the time, it was only natural to give it to an injured friend, but it seemed to mean a lot to her.
"If the inflammation has subsided, that's good enough."
"Aside from the wounds healing, my internal energy has increased. What is this pill?"
Yes, penicillin.
On Earth, it was a common antibiotic, but in the martial world, it was called a Divine Pill.
Making it was a pain since they had to grind high-quality ingredients instead of using electric motors like on Earth, but its effectiveness was immediate.
Jin Cheon-hee said, "Still, thank you."
"You're too kind for your own good."
Instead of replying, Jin Cheon-hee gave Wang Gak-yeon a nod and went inside.
Inside the curtain was a bed.
On the bed, a young boy was asleep.
Little Heavenly Demon, Yeo Ha-ryun.
"Asking Gak-yeon for help was the right decision."
Jin Cheon-hee approached Yeo Ha-ryun, who was asleep due to the effects of the medicine.
While helping with the treatment, Wang Gak-yeon had searched Yeo Ha-ryun.
She found him unconscious in a cave, changed his clothes, and secretly moved him to the medical hall's branch.
Since Yeo Ha-ryun had just killed a bear before collapsing, it was easy to make up a story.
Yeo Ha-ryun was a reckless young martial artist who had bravely fought a bear, and due to his special relationship with Jin Cheon-hee, the branch leader, he was secretly given the annex.
After moving him, Wang Gak-yeon reported,
"That kid's crazy. He took down a bear in that state."
His sword was broken, so he had used his fists.
After moving Yeo Ha-ryun and completing the initial treatment, the former Sect Leader of the Open Fist Sect was also moved to the medical hall.
Jin Cheon-hee had been shuttling between the two, treating them both.
"My master is truly amazing. The Zhuge family's formations can even deceive the eyes of the Open Fist Sect."
Of course, the former Sect Leader was recuperating, and the new Sect Leader was busy taking care of him, so they had no time to worry about anything else.
Still, Jin Cheon-hee gave a mental thumbs-up to his master.
Jin Cheon-hee carefully grabbed Little Heavenly Demon's wrist and began to check his pulse.
Perhaps due to the medicine, the boy was sound asleep even as his wrist was held.
"Hmm, he's almost fully recovered. Whew, I'm amazing too. I saved the former Sect Leader and secretly treated this guy."
As he was praising himself, a voice echoed.
"So that's what happened, Hee-ya. You treated him in secret. Without telling your master..."
It was a familiar voice.
His heart sank, and a chill ran down his spine.
"Master...?"
At the same time, Yeo Ha-ryun, who should have been asleep due to the medicine, opened his eyes.
"Hey, uh...!"
Before Jin Cheon-hee could say anything, Yeo Ha-ryun threw whatever was in his hand.
Clang!
It was a wooden mandarin duck carving.
No one could understand why throwing wood made a metallic sound.
And his master didn't even blink, blocking Yeo Ha-ryun's attack.
"Ahhh! What kind of mess is this?!"
It was chaos.
Behind his master, Wang Gak-yeon flapped her hands with an apologetic expression.
"I see you've met before."
"Ah, Master, wait a moment!"
This couldn't go on.
He had to do something, anything.
As Jin Cheon-hee tried to shield Yeo Ha-ryun, the boy instead grabbed Jin Cheon-hee's arm and hid behind him.
"Why is this kid so strong?"
It was the kind of brute strength befitting a protagonist.
And with the demonic arts he had learned, his strength was even greater.
His arm hurt, but Yeo Ha-ryun didn't seem to be exerting any effort, which was strange.
Not liking this scene, a wrinkle formed on Baekrin's forehead.
"The aura of the Heavenly Slaughter Star. I didn't realize it when he was young, but now it's clear. Hee-ya, did you really go through all that trouble to treat 'that thing'?"
His master had changed his reference from 'child' to 'that thing.' Jin Cheon-hee knew what that meant.
"He doesn't see him as human anymore?"
If so, there was only one answer.
Jin Cheon-hee was startled and shouted,
"M-Master! Even though he has the Heavenly Slaughter Star, he's a good kid!"
"Hahaha, saying a wolf eats grass is less absurd than this."
His master added,
"Hee-ya, do you know why the Heavenly Slaughter Star becomes the enemy of the martial world? The Heavenly Slaughter Star finds the sensation of life, meaning, and purpose through killing. That's why those born under the Heavenly Slaughter Star, even if they're children, have always been hunted."
His master's long silver hair flared up for a moment.
But Jin Cheon-hee thought the reason he wasn't attacking was because of his presence.
Sure enough, his master said,
"Hee-ya. Can you tell 'that thing' something for me? Tell him to let go of my disciple with those filthy hands."
It seemed that having the Heavenly Slaughter Star holding his disciple was driving him mad.
This situation needed to be calmed down.
In the tense atmosphere, Jin Cheon-hee calmly spoke,
"Let go, Ha-ryun."
Yeo Ha-ryun, baffled, replied,
"Why are you just repeating what he says?"
It seemed Yeo Ha-ryun didn't like that.
He said,
"I knew your master was Baekrin, but this won't do. Brother, come with me to the Demon Sect. I've built a good foundation, so it'll be fine. You don't even need to take the Blood Test to join."
What on earth was this kid doing in the Demon Sect?
It seemed he wasn't following the official promotion path described in the novel.
"Why all of a sudden?"
"In the past, I didn't know, but now I understand. Why do the martial world's doctors have colder eyes than the old demons of the Demon Sect?"
Jin Cheon-hee suddenly remembered what Gong-gwi had said in the past.
At the time, Gong-gwi had picked up a stone from the ground and said,
"With my long experience as an assassin, it seems the doctor smiles the same way at this stone and at people. That's why I got impatient."
That's why he had taken Jin Cheon-hee hostage.
To Zhuge Lin, Jin Cheon-hee was the only one who wasn't a stone.
He hadn't expected a similar story to come from Yeo Ha-ryun's mouth.
"You're mistaken."
"Am I? From what I see, you've got more blood on your hands than most mad demons."
"..."
Could he really sense that just from the atmosphere?
He knew his master had avenged the Zhuge family's enemies.
Blood must be repaid with blood.
The novel didn't detail what exactly Baekrin had done, but it mentioned that the elders of the martial world still feared him.
"But this was all just to avenge the massacre of his family."
Jin Cheon-hee felt a tightness in his chest.
This was a terrible situation.
The Heavenly Demon and his master were both talking past each other, with Jin Cheon-hee caught in the middle.
Of course, they were speaking to each other, but it couldn't be called a real conversation.
The stress was making his stomach ache.
With a mind chanting prayers, Jin Cheon-hee said,
"First, Master, Ha-ryun isn't a bad kid. Even though he has the Heavenly Slaughter Star, he's been living abstinently, and he didn't kill the Sect Leader of the Open Fist Sect—no, the former Sect Leader."
"Hee-ya."
"I've already sent the medical report to the main hall, so you must have seen it on your way here. Otherwise, you wouldn't have come to this branch."
Then it was Yeo Ha-ryun's turn.
"Ha-ryun, this is my master. I don't know what you're thinking, but if you dare say such things to my master, I won't stand for it."
"Brother?"
"I was only able to treat you because of the medical skills I learned from my master."
Since reading martial arts novels, he had always thought,
"Why don't you guys just talk to each other?!"
It was frustrating to see even minor conflicts escalate into lifelong enmity just because they wouldn't talk.
So, Jin Cheon-hee tried to initiate a conversation.
Communication was precious.
Especially when his master and the Heavenly Demon were exuding killing intent, nothing was more important than this.
It seemed Jin Cheon-hee's attempt worked, as Yeo Ha-ryun relaxed his killing intent and let out a sigh.
