The heavens above the Moon-Pale Cave curdled into a violent whirlpool of ink. In a heartbeat, the humid night air turned frigid, heavy with the suffocating scent of rain and ancient earth. The very atmosphere seemed to groan under the weight of an impending divine wrath.
BOOM.
A pillar of jagged, white-hot lightning descended from the firmament, striking the Great Serpent directly upon its calcified crown. The impact was not a killing blow, but a catalyst. The beast recoiled, its massive body thrashing with a primitive, celestial fury that sent tremors through the limestone bedrock.
The glowing chains of the Five-Element Seal, once so certain and absolute, began to splinter like fragile glass under the pressure of the serpent's surging Saiki.
"Hssss... CRRRR!"
The sound was a grating chorus of stone grinding against bone. With a final, bone-shaking heave that made the mountain seem to bow, the Great Serpent shattered the array.
Shards of blue spiritual light were cast into the weeping darkness like dying stars, dissolving into the mist before they could touch the mossy ground.
"Ha…" Yorimitsu spat a mouthful of metallic-tasting crimson, his small, dirt-caked fingers white-knuckled upon the hilt of his blade. "I knew it was far too simple a snare for a king of the deep woods. A Moulting King is still a King, after all."
The snake's jaw unhinged with a wet, sickening crack, stretching wider than any natural creature should permit. Its gullet began to glow with an incandescent, sickly hue, a violet heat that made the air shimmer and warp. It exhaled. This was no longer the Ghost-Fog of illusions; this was a concentrated stream of Miasmic Purple Flame.
The toxic breath hissed through the air with the sound of a thousand boiling kettles. Wherever the purple fire touched, the world simply ceased to be. Ancient cedars vanished into grey ash; the stone floor of the clearing liquefied into bubbling, obsidian slag.
"Tch... that is dangerous," Yorimitsu hissed.
He sought to blur into the shadows, his mind already calculating the trajectory of his escape, but the beast's instinct was swifter than his unrefined body. Its massive tail, a mountain of undulating muscle and translucent scales, whipped through the air with the speed of a falling star.
CRACK.
The blow caught him mid-air. Yorimitsu felt the world invert. He was cast into the suffocating darkness, his small frame smashing through the trunks of two thick pines. The wood snapped like dry kindling before he slammed into a moss-covered boulder. The world turned to a grey haze. His vision swam with embers of fire, and for a terrifying second, he forgot how to breathe.
He groaned, his body arching in a rictus of agony as he forced himself to rise. Every nerve ending screamed in protest. His ribs sang with a sharp, piercing pain that suggested at least two had cracked, and for a heartbeat, his spirit faltered. Yet, beneath his torn hemp robe, a searing heat bloomed against his chest.
A Stone Talisman, which he had painstakingly inscribed upon his skin, flickered one last time with a golden, protective light before burning into black ash.
If I had not the foresight to anchor this seal to my flesh, he mused, his internal voice as cold and steady as a winter stream, I would be nought but a bag of shattered bone and wasted potential.
He looked at his trembling hands. "I guess no matter how much Reiryoku you train, this small, fragile frame is still just that, a child's vessel."
He stood tall, the blue spiral on his brow pulsing in a slow, rhythmic harmony with his ragged breath.
He reached down and retrieved the rusted blade; the Thunder-Clap Sutra bound to the hilt now hummed, feeding off the residual electricity still crackling in the humid air.
He settled into a low, lethal stance, the tip of his steel pointed at the twin pools of toxic gold that were the serpent's eyes.
"It is time, all must come to an end, even a great beast such as yourself," he whispered, the wind of his Reiryoku beginning to howl around his feet, whipping his hair into a frenzy.
"Fall!" he murmured.
From the churning charcoal heavens, hundreds of arrows suddenly came raining down, their tips burning a red-hot flame.
Yorimitsu raised his left hand, his fingers dancing in the air like a puppeteer's. As his fingers twitched and curled, the flaming arrows responded in mid-air. They did not fall in a straight line; they curved, spiralling and darting like a school of carnivorous fish.
The Great Serpent hissed, its golden eyes darting frantically. It began to move with its characteristic disjointed grace, flickering its massive body to the side, twisting and coiling to avoid the crimson rain.
Thwack! Thwack! Thwack! Several arrows struck the ground where it had been a millisecond before, exploding into blossoms of red fire.
The beast grew arrogant. It sensed the hollow nature of the projectiles. With a contemptuous flick of its tail and a series of rapid, blurring movements, it dodged the main cluster of the volley. Many of the arrows passed right through its translucent scales without drawing blood, dissipating into harmless mist upon contact.
As the snake lunged forward to swallow the boy whole, its mouth agape and dripping with venom, it saw Yorimitsu's face.
He was smiling. A sharp, predatory smirk that made the serpent's instincts scream in sudden alarm.
"How can you fall for your own speciality?" Yorimitsu mocked, his voice cutting through the roar of the wind.
In a blur of movement that defied the limits of his small body, he vanished then.
SHING.
The rusted blade, now glowing with a blinding, incandescent blue edge, carved through the air. There was no resistance. The steel passed through the thick, armoured scales and the dense muscle of the neck as if it were cutting through morning mist.
The Great Serpent's head continued forward for a moment, its golden eyes still wide with shock, before it slid cleanly from its body. A fountain of pressurised, dark blood sprayed into the air, drenching the white-lichened rocks.
The massive body collapsed with a final, earth-shaking thud, coiling one last time in a mindless reflex before going still. Yorimitsu stood amidst the carnage, the rusted blade dripping with the ichor, his breath finally evening out as the storm above began to break.
