The abandoned watchtower did not feel like a place meant for human habitation. Moisture clung to the stone walls, carrying the smell of rust and moss, and the ceiling dripped steadily where rainwater seeped through cracks no one had bothered to repair for years. Yet to Mu-Hyuk, it felt safer than any of the polished halls he had once trained in. This ruin had no witnesses.
While Yoo Seol-Ah slept fitfully against a pile of collapsed timber, Mu-Hyuk remained awake, seated cross-legged with his back to the wall. His breathing was slow, almost meditative, but nothing about the process resembled orthodox cultivation.

Every confrontation from the night replayed through his senses in abstract patterns. Where a normal cultivator would seek harmony of qi, Mu-Hyuk's system sought optimization. It trimmed excess motion, reinforced weak muscular chains, and fine-tuned neural reflex arcs until even unconscious movements aligned with lethal intent.
This was not training.
This was reprogramming.
At dawn, the Azure Sun Sect stirred back to life.
Bells rang faintly across the mountainside, calling disciples to morning drills. From their hidden vantage point, Mu-Hyuk watched the outer courtyards fill with figures moving in practiced formations. They laughed. They complained. They lived as though yesterday had been nothing more than another forgettable cleansing.

Mu-Hyuk turned to Yoo Seol-Ah as she woke, her eyes still clouded with exhaustion.
"You know where the injured go after purges," he said.
She nodded slowly. "The auxiliary infirmary. They don't bring outer disciples to the main halls unless an elder orders it."
"Good. That's where we start tonight."
Her brows knit together. "Start what?"
He didn't answer directly.
By evening, whispers had already begun spreading through the outer ranks. Three disciples missing. Patrol logs inconsistent. A fire extinguished in a courtyard where none had been scheduled.
None of it was enough to cause panic.
Not yet.
Mu-Hyuk walked openly through narrow alleys that only servants used, the system blurring his presence just enough that passersby would forget him moments after glancing his way.

The auxiliary infirmary stood at the edge of the outer district, a squat building reserved for those deemed too unimportant for proper care. Its doors were never locked.
Mu-Hyuk paused outside.
"This place holds people who won't be missed immediately," he said to Yoo Seol-Ah. "People who've already been written off."
She stiffened. "You're not planning to—"
"I'm planning to remove instability," he replied.
Inside, low moans drifted through the corridors. Disciples nursing broken limbs, shattered meridians, cultivation backlash — casualties of ambition and neglect. The same fate that had nearly claimed him.
Mu-Hyuk stepped forward.
The foundation of the Azure Sun Sect had begun to fracture.
And tonight, he would widen the fault lines.
