Residence of the Spring Clan's Demonic Heir
Southeastern Quarter, within the walls of the Heavenly Demon Divine Cult
The Spring Clan estate bloomed even in stone.
Carved pillars shaped like unfurling blossoms lined the courtyard, lantern light flickering softly across polished jade tiles. Servants stood at a distance, silent as shadows.
Inside the main hall—
A porcelain cup shattered against the floor.
"I asked them to dispose of a piece of bothersome trash…"
Cheon Mukeum's voice was smooth, but something volatile coiled beneath it.
He stood before the assassin, long brown hair flowing freely down his back, robes of pale green silk embroidered with subtle floral patterns — the emblem of the Spring Clan stitched over his chest.
"…and all five of them are dead?"
The kneeling assassin kept his forehead pressed to the cold floor. Blood stained the edge of his sleeve — not his own.
"It would appear… a hidden master intervened, Young Master Mukeum."
The air shifted.
Mukeum turned slowly.
The movement was calm.
Too calm.
"How dare you call me by my given name?"
The assassin's body trembled violently.
"I—I beg forgiveness! Young Master Cheon!"
For several heartbeats, only the wind outside could be heard.
Then—
A soft chuckle.
Mukeum waved his sleeve dismissively. "Stand. You're shaking like a dog in winter."
The assassin rose, but did not dare lift his head.
Mukeum turned his back, walking toward the open veranda. His fingers tapped lightly against the wooden railing.
"I separated him from his guards," he muttered, more to himself than anyone else. "Chose the hour carefully. No witnesses. No interference."
His eyes narrowed slightly.
"And yet… five trained killers lie dead."
Silence stretched.
A hidden master?
Unlikely.
The boy had been nothing more than a powerless disgrace — a son born of a lowly woman.
Mukeum's thoughts sharpened.
'I ensured he was isolated.'
'Unless… someone else is watching him.'
His gaze lifted toward the distant central spire of the Cult — where the Lord of the Demonic Cult resided.
'Father?'
The idea unsettled him.
He raised his hand slowly, examining his fingers in the lantern light.
"I wished to avoid dirtying these hands," he said softly. "It would have been unsightly."
His lips curved into a thin smile — not warm, not amused.
Predatory.
"But it seems I have no choice."
He turned, eyes glinting.
The assassin stiffened.
Mukeum's voice dropped, smooth as silk over a blade's edge.
"Cheon Yeo Woon…"
A faint killing intent seeped into the room, chilling the air despite the spring motifs that adorned the estate.
"I will kill you myself."
"At the Demonic Academy."
...
Cheon Mukeum strode through the Spring Clan estate, his long brown hair trailing over the flowing silk of his robes. Already a First-Rate warrior, he carried himself with the calm confidence of someone who knew he was untouchable.
Yet… his eyes wandered.
The maids, scurrying quietly through the halls, moved like water. And Mukeum's gaze lingered—just a little longer than it should. He smirked. Over the past year, he had cultivated a subtle… indulgence. He had requested maids of a certain… generous build. Not for frivolity alone. No, he derived a sort of entertainment from watching them, from letting the quiet luxury of his power brush against his personal whims.
He entered his training chamber. The familiar air smelled faintly of incense and polished wood, the space empty and still. Without hesitation, he assumed the stance of the Spring Demon Fist, the signature martial art of the Spring Clan.
Hours passed in fluid motion. His fists struck, his body shifted, his internal energy pulsed. When he finally ceased, sweat dampening his brow, he gave a satisfied nod and left the room, heading to his private quarters.
Within the library of his chambers, he approached a hidden compartment and pushed it open. Inside lay a leather-bound manual: Poison of Destruction. His lips curved into a thin smile. This was the martial art of Cheon Jongsum, the Poison Clan's heir.
A memory flickered. A year ago, Mukeum had tricked Jongsum, stolen the manual, and kept it just long enough to copy it before leaving it where the Poison Clan could find it. Clever, subtle, invisible—the perfect Spring Clan heir move.
The Spring Demon Fist was formidable, yes—but if he wished to become the Demon Lord, greatness alone was not enough. For the past year, he had been preparing his body, gradually exposing himself to small amounts of poisons to condition his meridians, his organs, and his internal energy. Now, the time had come to begin proper training in the Poison Arts.
From another hidden compartment, he retrieved a potent, venomous herb. Sitting cross-legged, he ingested it. The toxin slithered through his body, biting at nerves, corroding tissue, yet restrained by the quiet discipline of his internal energy.
"Now…" he murmured internally, focusing on the manual's first instructions. "Circulate it throughout the meridians… refine it…"
Minute by minute, he forced the poison to flow, letting his internal energy wrap around it, turning the corrosive substance into something resembling pure energy. He could feel the transformation, could feel his body learning to resist the deadly bite of the toxin.
"And finally…" His eyes narrowed as he moved to the final basic step: storing the poison in the Lower Core. He concentrated, gathering the corrosive energy at the center of his dantian, forcing it to submit, to stabilize.
After a tense silence, the process completed. The poison was no longer a threat; it was contained, refined, and controlled, encased within layers of his Internal Energy.
Panting, exhausted from the strain, Cheon Mukeum leaned back slightly. A thin smile spread across his face. He raised a hand, and with a mere thought, a droplet of poison seeped from his fingertips.
