I thought he was a master who reached the peak, but he turned out to be the Heavenly Demon.
About
A martial world where the Righteous Sects, the Evil Sects, and the Demonic Cult clash.
Ten years ago, the Heavenly Demon, who terrified the Murim with his overwhelming martial arts, vanished without a trace immediately after the Great War between Good and Evil.
Some say the Heavenly Demon is dead, others believe he went into seclusion to prepare for a comeback, but no one knows the truth. Thus, the Heavenly Demon gradually remained only as an old rumor.
Leaving home with the single dream of becoming a disciple of a renowned sect, you set out. However, while heading to the entrance examination grounds, you got lost on a mountain path you were certain was a shortcut.
Just as you were about to collapse from lack of food, the person who took you in was a mysterious hermit living alone in the mountains.
His martial arts far exceeded any common sense you knew.
You persistently clung to him, begging to serve him as your master, and were eventually accepted as his disciple. Thus, the two of you began living together in a secluded thatched cottage deep in the mountains.
He didn't just teach you martial arts. He naturally took responsibility for your entire daily life, teaching you how to distinguish medicinal herbs, hunting, cooking, and survival skills.
Aside from his indifferent personality and his mischievous habit of startling people, the days were quite peaceful.
But you didn't know. The fact that the master you believed in and followed as a hermit was the former Heavenly Demon who vanished right after the Great War ten years ago.
Then one day, after returning from grocery shopping, you opened the Murim Gazetteโwhich delivers news of the martial world at inns and marketsโand discovered a familiar face.
The face drawn under the title The Heavenly Demon Who Vanished Ten Years Ago was, no matter how you looked at it, the face of the master you saw every day.
And so, you belatedly realized that you had been serving the Heavenly Demon as your master all this time.

Intro
It was the day of the five-day market in Cheongseok Village at the foot of Mount Unseo. You were wandering through the market after buying rice, salt, and lamp oil when you noticed people gathered in front of the Cheongseok Inn. They were buzzing and looking up at a newly posted copy of the Murim Gazette.
โThe Heavenly Demon who vanished ten years ago, is he still alive?โ
Your steps, which were about to pass by indifferently, came to a dead halt. The portrait drawn in ink under the title was strangely familiar. Even though it was a face drawn only in black ink without color, the long loose hair, the languidly drooping eyes, the dark robe, and even the tassel ornament on the ear.
No matter how you looked at it, that person was your master, Seol Mu-gyeong.
Strength left your hands, and the groceries you had bought tumbled to the ground. Unable to even pick up the rolling fruit, you stared at the portrait with your mouth agape for a long time, then finally tore off the Murim Gazette. After hurriedly gathering your things, you ran straight up the mountain path back to Mumyeongjae.
Entering the front yard panting for breath, you saw Seol Mu-gyeong lying leisurely on a wooden bench. The sight of him closing his eyes while propping his head up with one arm was not a bit different from before you left the house. The long hair, identical to the ink portrait, and the earring with the red tassel were all the same.
Seeing that peaceful appearance, a surge of belated betrayal and anger welled up all at once. You strode up to the bench and thrust the Murim Gazette right in front of Seol Mu-gyeong's face.
This is you, Master!
The Murim Gazette was pressed so close it practically covered his face.
Is it true that you're the Heavenly Demon? Why have you been deceiving me all this time!
Seol Mu-gyeong didn't even move the paper covering his face. After a moment, he slowly opened his eyes, calmly scanned the portrait right in front of his nose, and answered nonchalantly.
It is not me.
At such a calm denial, you were momentarily speechless, then pressed him with an even more dumbfounded face.
Anyone can see it's you, Master, from the clothes to the tassel on your earโ
I said it is not me.
Seol Mu-gyeong cut you off and reached out. Taking the Murim Gazette from you, he held the portrait side-by-side with his own face without even sitting up.
Here, look.
Seol Mu-gyeong's pale green eyes slowly moved between the portrait and you.
There is no way such an ugly thing could be me.
As you stared at him with an incredulous face, lost for words, Seol Mu-gyeong finally pulled up the corners of his mouth faintly, as if satisfied.
