The cold white mist that hung over the central chamber of the Silent Under-basins drifted slowly, parting to reveal the frozen forms of Heishui's guards resting like pale stone statues beneath the black water.
In the center of the wet limestone chamber, Investigator Zhou Yan and Alliance Master Heishui stood back-to-back, their breath rising in rapid, white plumes. Before them, the young teenager in damp outer disciple robes stood in silence, his boots resting flat on a thin layer of blue ice that had crystallized over the dark water.
Heishui's scarred face twisted with a mixture of raw fury and creeping hesitation. He was a veteran of the rogue paths, a cultivator who had fought his way to the peak of the Core Formation Realm. Yet, looking at the calm, pale face of the youth, his instincts screamed of danger. The silence in the cavern chamber was absolute, save for the slow drip of water from the ceiling and the rapid pounding of Heishui's own heart.
"Who are you?" Heishui snarled, his voice echoing off the vaulted stone ceiling. "You faked the shell of a mortal copyist, yet you systematically executed my guards without drawing a single weapon. You are not a simple rogue. Speak your name!"
Fang Lin did not answer. He stood with his arms hanging loosely at his sides, his dark eyes quiet, reflecting the pale green light of Heishui's crescent blade. To Fang Lin, the enemy's questions were meaningless. In combat, speech was a waste of breath. The decision to fight had already been made, and the only logic that remained was the final result.
He took a single, slow step forward, the ice beneath his boots crackling softly.
"Arrogant rat!" Heishui roared, his patience breaking under the pressure.
Surging forward, Heishui swung his heavy black crescent blade in a massive, horizontal arc. A violent wave of corruptive green water Qi erupted from the glowing runes along the steel, carving a deep groove into the wet stone floor and throwing up a screen of freezing black water. The density of his peak Core Force was immense, a heavy, suffocating pressure that filled the cavern chamber and threatened to crush the breath of any ordinary cultivator.
Fang Lin did not retreat. He shifted his body, his boots gliding across the frozen surface of the water with the fluid speed of the Flowing Wind Steps. He bypassed the main force of the crescent blade by a fraction of an inch, the corruptive wind of Heishui's Qi snapping the hem of his dark robes.
Appearing directly to Heishui's left, Fang Lin struck.
His palm shot forward like a white flash in the darkness, his parallel meridians humming as he channeled a concentrated burst of Frost Qi. The palm strike hit Heishui's side with a solid, echoing crack, vibrating through the limestone floor.
However, Heishui's body was enveloped in a dense, defensive layer of dark-water Qi that acted like a thick sheet of swamp clay. The Frost Qi erupted, freezing the outer layer of Heishui's barrier, but the corruptive swamp force inside the barrier quickly corroded the ice, dissolving it into warm water vapor. The raw energy quantity of a peak Core Formation cultivator was vast, and without a medium to focus his Law comprehension, Fang Lin's unarmed strikes could not penetrate the defense.
Heishui laughed, a harsh, grating sound of relief. He felt the cold pressure, but realizing his barrier had held, his confidence returned.
"Your Frost Qi is pure, indeed!" Heishui mocked, swinging his crescent blade backward to force Fang Lin to leap away. "But your cultivation realm is too low! You are nothing but a Late Spirit Foundation rat! Without a weapon, you cannot even scratch my Core Force shield!"
Heishui did not waste time. He raised his crescent blade high, his scarred face twisting with greed. The green runes along the steel flared with blinding intensity, and he slammed the pommel of his heavy weapon onto the wet stone slab.
"Swamp Deluge!" Heishui shouted.
The stagnant black water on the chamber floor suddenly boiled. A thick, foul-smelling swamp water rose from the depths of the flooded basin, turning into three massive, swirling columns of dark water Qi that raced toward Fang Lin from three sides. The columns carried a corruptive, corrosive force that could melt the flesh and meridians of ordinary cultivators in seconds.
Fang Lin retreated to the edge of the chamber, his back resting near the cold limestone wall.
He looked at the three columns of swamp water closing in. The raw power of Heishui's peak Core Force was vast, and the narrow constraints of the cavern chamber left him little room to dodge. He realized that faking his mortal shell and fighting unarmed was no longer viable. To kill a peak Core Formation master swiftly and prevent any warning from escaping, he had to use his full strength.
Fang Lin reached his hand toward his storage pouch.
With a soft, metallic whisper that seemed to echo through the very bones of the cavern, he drew the Night Burial Sword.
The hiltless sword was thin, pitch-black, and had no sheath. The moment the steel emerged, the ambient green light from Heishui's crescent blade was instantly absorbed by the blade, leaving the chamber in a cold, absolute gloom. The air around the sword turned heavy with the quiet scent of decay and stillness, the water droplets on the limestone ceiling freezing mid-fall and shattering against the stones.
Investigator Zhou Yan, who had been watching the fight from the safety of the rear slab, locked his gaze onto the thin, pitch-black blade.
His heart, which had been racing, suddenly froze.
He stared at the sheathless, pitch-black steel. He looked at the calm, pale face of the youth, and then back at the sword. A memory, sharp and terrifying, flashed through his mind—an intelligence report he had read weeks ago regarding the battle at the canyon outside the ruins.
A teenager in dark robes... holding a thin, pitch-black, sheathless spirit sword... who had slaughtered Heng Wuchen of the Demon Suppression Temple... whose name was Shen Mo.
"Silent Mountain Sword..." Zhou shrieked, his voice rising into a high-pitched, trembling shriek of absolute terror. "Shen Mo! You are the Silent Mountain Sword!"
Heishui's hands froze on his crescent blade, his small eyes widening. "What? Zhou Yan, what nonsense are you shouting? The Silent Mountain Sword is a reclusive expert who vanished after the canyon clash! Why would he be here faking a mortal copyist in a small county?"
"Look at the sword!" Zhou screamed, his face completely pale, his boots slipping on the wet stone as he backed away. "The thin, pitch-black steel that absorbs the light... the absolute stillness... it is him! He slaughtered the Temple's legacy disciple and senior elites! We have cornered a monster!"
Zhou Yan did not wait for Heishui's response. He was a veteran of the rogue paths, a survivor who had lived for over a century by knowing exactly when to run. He knew that if the youth before them was truly "Shen Mo," then Heishui's peak Core Force was nothing but a joke. They were already dead if they stayed.
Reaching into his inner robe, Zhou Yan grabbed a dark-red, ancient parchment talisman—a rare, blood-burning Spatial Escape Talisman that he had purchased for an exorbitant price decades ago.
He bit his tongue, spitting a mouthful of hot blood Qi directly onto the runes of the talisman.
"Master Heishui, save yourself!" Zhou shrieked.
"Zhou Yan! You coward!" Heishui roared, realizing what his ally was doing.
The talisman flared with a violent, blood-red spatial light that wrapped around Zhou Yan's body, his figure beginning to dissolve into the coordinates.
Fang Lin's eyes narrowed. He took a step forward, the Night Burial Sword swinging in a swift arc, a thin blade of black frost Qi cutting through the mist toward Zhou's neck.
But the spatial talisman was already active. The coordinates locked, and with a sharp, echoing crack that shattered nearby stalactites, Zhou Yan's figure vanished in a flash of blood-red light, teleporting directly out of the Silent Under-basins and escaping the cavern arrays.
The blood-red light died down, leaving the central chamber silent once more.
The black water on the floor slowly settled, the mist rolling back over the frozen bodies of the guards.
Alliance Master Heishui stood alone on the central limestone slab, his scarred face pale under his dark hair. The green runes along his black crescent blade hummed, but the sound felt weak and hollow in the vast silence of the cavern. All five of his elite guards were gone, systematically executed without a single clash of weapons.
He looked at the teenager standing ten meters away.
Fang Lin held the Night Burial Sword low, its cold tip tracing a thin line of black ice across the water. His dark eyes were fixed on Heishui, carrying no anger, no greed, and no hesitation.
"Zhou Yan has run," Fang Lin said, his voice flat and quiet, echoing through the dark cavern. "Now, it is just you."
Heishui gripped the leather-wrapped hilt of his crescent blade, his teeth bared in a desperate, vicious snarl as the cold mist began to freeze the surface of his heavy weapon, the final battle about to begin in the freezing silence of the deep earth.
---
The freezing wind inside the limestone chamber did not blow; it hovered, a heavy, silent presence that turned the rising mist into falling needles of frost. Fang Lin's dark disciple robes, though damp from the swamp water, clung to his body like a second skin, showing no movement. In his spiritual sea, the grey seed remained quiet, its surface pulsing with a soft, steady light that anchored his Parallel Meridians.
Across from him, Heishui felt the atmospheric change. The peak Core Force he had spent decades refining—a dense, corruptive swamp Qi that had drowned dozens of rivals in the northern marshes—felt sluggish. It was not because his energy was lacking, but because the cold in the chamber was no longer a simple temperature drop. It was a law of freezing stillness, a force that demanded everything in the cavern stop moving, stop breathing, and stop circulating.
"Shen Mo..." Heishui whispered, the name tasting like dry ash. He looked at the thin, pitch-black blade. The sword had no decorations, no glowing runes, and no flowing light, yet Heishui's crescent blade was trembling. The corruptive green water Qi, which usually hummed with the screams of swamp beasts, was being absorbed by the pitch-black metal, drawn into a silent void that left no trace.
"Zhou Yan is a coward," Heishui said, his voice dropping to a low growl as he stepped off the limestone slab, his heavy boots sinking into the black water. "He fled because he fears the name of a genius. But a genius who has not reached the Core Formation Realm is still nothing but a Spirit Foundation cultivator. Your meridians may be wide, and your sword may be sharp, but my dantian holds a peak Core. If I must die in this cavern, I will drag your legacy down with me!"
Heishui did not wait. He bared his teeth, his scarred face turning red as he ignited a portion of his Core essence. The green water Qi around his crescent blade erupted in a massive, corruptive wave that was twice as large as before. The black water on the floor rose in a violent, swirling vortex, turning the entire chamber into a churning basin of swamp mud and dark water.
Fang Lin watched the deluge approach. His hand on the hilt of the Night Burial Sword was steady, his mind completely quiet. The Will of Stillness inside his soul resonated with the pitch-black steel, and as he raised the sword, the white frost on the cavern walls began to crawl toward Heishui, the final clash of their paths moments away in the dark depths of the Silent Under-basins.
The cavern shook, the limestone columns cracking under the pressure of the rising water, the silence of the cavern swallowed by the roar of the swamp deluge as Heishui charged forward, his crescent blade cutting a path through the mist, while Fang Lin stood waiting, his dark eyes reflecting the green light of the blade.
