Deep within the demonic cult's inner sanctum, inside a pitch-black training hall where even light dared not enter, the Demon Sword King stood alone. Silence hung like fog in the air, broken only by the subtle sway of his crimson robes. In his hand was a report—meticulously written by Heukyeom and Dokyeon—detailing the battle between Lee Do-Hyun and Heukyeom, ending in the latter's defeat.
A sharp, cold smile curved on the cult leader's lips.
"Lee Do-Hyun… and he only managed to defeat Heukyeom?"
He slowly rose, stretching his body in fluid, measured motions. His breath flowed like wind over still waters, and the movement of his fingertips carried a grace both mesmerizing and deadly. When his blade sliced through the air, it did so with an elegance that defied comprehension—a dance somewhere between divinity and death, not unlike the legendary Eastern Invincible.
"His level of martial prowess is still too low. Barely able to overcome Heukyeom... it was a close call at best."
He spoke softly, almost to himself. The Demon Sword King knew that if Heukyeom had unleashed his full power, Lee Do-Hyun would not have stood a chance. But in the cult, only results mattered. Strength was measured by victory, not effort. No matter how skilled Heukyeom was, the fact remained: he lost.
"In the end, only results define truth."
A chuckle escaped him, low and amused.
He stared again at the report. "Lee Do-Hyun… he is unlike me. Yet, he is shaking the foundations of the martial world—and in a way I never could."
The cult leader raised his blade high, gazing into the shimmering edge.
For years, the martial world had balanced uneasily between the orthodoxy, the unorthodox sects, and the demonic cult. But Lee Do-Hyun, with his ideals and his creation—the Heukwoon-gwan—was threatening to shatter that fragile structure. It was not power, not bloodshed, but unity with the weak that drew others to his cause.
"A method I could never embrace… but fascinating, nonetheless."
The Demon Sword King found himself gripped by an unfamiliar curiosity. He could not comprehend Do-Hyun's vision, yet he could not deny its influence. Perhaps, in some way, this was the very evolution he had sought for the cult all along—an unexpected path to shaking the world.
"If his ideals can truly reshape this world, what does that say about the strength I've spent a lifetime pursuing?"
He lowered the blade and murmured to himself.
The desire to test Lee Do-Hyun's vision himself—to see whether ideals could indeed be forged into power—began to stir within him.
With a wave of his hand, he summoned the elite members of the cult: the Black Veil Corps. Heukyeom and Dokyeon stood at attention as he swept his gaze over them.
"Watch them closely. Let no movement of Heukwoon-gwan escape our notice. When the time comes, I will face them myself."
He slashed his sword through the air. His energy rippled out in a violent wave, causing the very atmosphere around him to tremble. His strikes were beautiful and deadly—an art form that only one like him could perform.
"It's time I step into the light... and test the worth of their so-called unity."
His blade returned to its sheath with a soft hiss. There was no longer only conquest in his eyes, but a hunger—for challenge, for understanding, for something more than power.
"While the orthodox preach justice, and the unorthodox cry for freedom—I have always sought only strength. And yet, these people dare to shake the world with something else entirely. I want to know why."
He spoke once more before leaving the chamber.
"Justice, order, chaos—it all now lies between Lee Do-Hyun and me. Whether his ideals are true strength or mere illusions... I will find out soon enough."
And with that, the Demon Sword King vanished into the darkness, his steps silent yet certain. He was moving toward the center of the storm.
The martial world would never be the same again.

The Hidden Master, Cheong-Yeon
Heukwoon-gwan appeared peaceful, but beneath that calm lay a palpable tension. Sunlight glinted off drawn blades as trainees immersed themselves in rigorous practice, their movements sharp and deliberate. In the center of the training grounds stood Director Lee Do-Hyun, eyes alert. Ever since various factions had begun circling Heukwoon-gwan—tempting, probing, provoking—he had grown acutely aware that conflict could erupt at any moment.
That afternoon, a stranger appeared at the gates.
She was a woman with a simple appearance, carrying a black wooden training sword. She introduced herself as a wandering swordswoman—her name: Cheong-Yeon. Nothing about her outward appearance stood out, but in her gaze, there was a depth of composure and an inner force that belied her unassuming facade.
In truth, Cheong-Yeon was none other than the Demon Sword King—the leader of the demonic cult. Feared and revered across the martial world, she now stood in a different guise: transformed through a form of spiritual transmutation into the appearance of a young, ordinary woman. She had come to Heukwoon-gwan not to conquer, but to observe—to test its ideals, to measure its strength, and to meet the man who stood at its core.
The trainees guarding the gate eyed her warily. "May we help you?"
With a gentle smile, Cheong-Yeon replied, "I've heard of the Black Cloud Sword. They say your ideals bring a new wind to the martial world. I came to see if that wind is one I might walk with."
The tension eased slightly. The trainees escorted her inward.
Lee Do-Hyun greeted her personally, his expression neutral, his senses sharp. At first glance, there was nothing particularly remarkable about her. But there was something in her eyes—calm, yet cold—that made him hesitate.
"What brings you to Heukwoon-gwan, Lady Cheong-Yeon?" he asked plainly.
She bowed with humility. "I was moved by your ideals. I came to see if I might learn something here... or perhaps offer something in return."
Do-Hyun detected no malice in her voice, but recent events had left him cautious. He allowed her to remain within the grounds, though he made a mental note to observe her carefully.
The next morning, Cheong-Yeon demonstrated her basics before the trainees. Her movements were precise, efficient—more control than flair. Each strike, each step, was a testament to mastery beyond force. Her footwork flowed like water, and her measured strikes captivated the watching disciples.
Han So-Yeon, one of the most skilled among them, approached.
"Here at Heukwoon-gwan," she said, "we often speak through our blades. Would you spar with me?"
Cheong-Yeon smiled and raised her wooden sword. "It would be an honor, Lady Han."
The duel began. So-Yeon unleashed the Clearflow Sword Technique—a graceful, flowing style that sought to read and redirect the opponent. She struck with elegant precision, each move a study in balance and beauty.
Yet Cheong-Yeon deflected every strike with ease, never once revealing a hint of her inner power. Her footwork was effortless, her movements deceptively minimal.
"A beautiful technique," she murmured. "But when the water flows too gently, it becomes predictable."
With one fluid motion, she knocked So-Yeon's blade aside and brought the wooden tip to her neck.
So-Yeon gasped and lowered her weapon. The defeat stung, but she refused to let pride blind her. She had seen something in Cheong-Yeon's style—something she yearned to learn.
Next to step forward was Cheong Un-Jin. With his usual casual tone, he said, "If So-Yeon lost, I suppose it's my turn. Can't let Heukwoon-gwan's pride be dented too deeply."
Un-Jin's swordsmanship was direct and powerful, focused on relentless offense. He surged forward, pressing Cheong-Yeon with heavy strikes backed by solid internal energy.
But she evaded them all, as if she already knew where each blow would land. Her footing never wavered. His momentum slowly unraveled under her quiet control.
"Your strength is impressive," she said softly, "but relying too much on flow can make one's rhythm predictable."
With a few counters, she disrupted his stance and left him open. He stepped back, lowering his blade.
For a moment, he felt conflicted—not sure if he had been lacking, or if the woman before him was simply too strong. Awe and a quiet unease lingered in his gaze.
Watching closely, Baek Wol-Hee stepped forward. She had already gauged Cheong-Yeon's strength and planned to use her Moonlit Illusion Style to confuse and mislead her opponent.
Her technique relied on phantoms and misdirection, exploiting the opponent's hesitation to create openings.
But Cheong-Yeon saw through it all. She pierced through the illusions, her movements unfazed, her gaze fixed.
"An elegant art," she said. "But illusions, no matter how beautiful, cannot replace truth."
She countered Wol-Hee's final strike and struck the one true target.
Wol-Hee lowered her blade. "You are no ordinary master, Lady Cheong-Yeon. Your strength is truly... extraordinary."
Her voice held not just caution, but sincere admiration.
Then, finally, Cheong-Yeon turned to Lee Do-Hyun.
"I would like to see," she said, lifting her wooden sword, "if your ideals and your strength truly walk the same path."
Do-Hyun unsheathed the Ego Blade.
From the start, their duel was intense. His swordplay was precise, a union of force and finesse. He wove inner energy and mana into every strike. He fought with everything he had.
But Cheong-Yeon remained a step ahead. She never once released her inner power, yet she blocked every attack. Her movements were almost ethereal—at times resembling a dance, at others, a storm.
With a sharp smile, she whispered, "True strength lies not in skill alone, but in conviction—proven through results."
She began pushing him harder, testing his limits. She studied his blade.
"This sword... it's alive. It doesn't belong to this world, does it?"
Do-Hyun faltered, surprised. "Who... who are you really?"
She only smiled. She sheathed her weapon and stepped back.
Looking to the others, she spoke once more.
"Your path will be difficult. But I hope you'll find something that shines at the end of it."
And with that, she quietly left Heukwoon-gwan.
Her presence lingered long after. The trainees were left in awe, humbled by her strength—and reminded how far they had yet to go. So-Yeon, Un-Jin, and Wol-Hee each reflected on their defeats, knowing they had much to learn.
Lee Do-Hyun stood in silence, her final words echoing in his mind. He looked down at the Ego Blade and murmured,
"This sword… and I. What can we truly achieve in the martial world?"
Cheong-Yeon's presence would not fade so easily. In her wake, she left not fear—but a quiet question that stirred the hearts of all who had faced her.
