Hollow Technique: Purple, the Annihilated Demon King
Deep within the Infinity Castle, the space was exceptionally vast, resembling a gigantic abdominal cavity. Surrounding it were writhing wooden walls, like biological tissue, inlaid with tumors emitting a dim yellow light, like countless peering eyes. The air was thick, filled with a nauseating stench of aged blood and decaying matter.
Muzan Kibutsuji stood in the center of this space.
He had regained his youthful appearance, his black hair meticulously combed, his skin as pale as paper, and he wore a well-fitting black tuxedo. His crimson pupils gleamed with a cold, cruel light in the dim light. However, beneath this deliberately maintained elegance lay an aura of rage that could not be completely concealed. The energy within him surged like boiling magma, yet it was bound by some invisible shackle, causing the space around him to distort slightly.
Moyu appeared silently at the entrance. He walked steadily toward Muzan, and the ground beneath his feet rippled with subtle Azure light, quietly dispelling the unpleasant stench emanating from the surrounding area.
"You've come." Muzan spoke, his voice low and condescending, yet a closer listen revealed a barely suppressed impatience. "In hundreds of years, you are the first human... to humiliate me so much."
Moyu stopped about ten meters away from Muzan, a distance that meant they were both within attack range. He tilted his head slightly, looking at Muzan with a calm and even tone. "Is that so? I thought that compared to when I was hacked to pieces by Yoriichi Tsugikuni, desperately begging for mercy and fleeing in Yoriichi Tsugikuni, this experience wouldn't be anything."
"Shut up!" Muzan's elegant mask shattered instantly, his crimson pupils contracted sharply, and a violent aura surged into the Yoriichi Tsugikuni was the deepest nightmare and shame in his thousand-year life. Moyu's casual remark precisely pierced his most sensitive and most unbearable scar.
Boom--!
Without any warning, Muzan's arms instantly mutated and deformed, his skin tearing apart into two dark red whips nearly ten meters long, covered with sharp bone spurs and sucker-like mouths! The whips tore through the air, emitting ear-piercing sonic booms, and like giant pythons emerging from their caves, they crossed and strangled Moyu at a speed beyond the reach of the naked eye!
Its speed is so great that it can easily tear apart steel.
However, just as the tip of the whip was half a foot away from Moyu's body, it seemed to have hit an invisible, intangible, yet indestructible wall.
Bang bang--!
Two muffled thuds followed, and a violent shockwave spread outwards, cracking the ground like a spiderweb. But Moyu stood still, not even the hem of his clothes fluttering. He perfectly shielded himself from this violent attack.
"Hmm? This strange defense again!!" A hint of surprise flashed in Muzan's eyes, but the attack did not stop. The countless suction cup-like mouths on the whip suddenly opened, generating a huge suction force, trying to disrupt the space around Moyu. At the same time, the whip twisted flexibly, launching a continuous series of lashes from various tricky angles! The whip shadows filled the sky, completely sealing off the space around Moyu.
Snap! Snap! Snap! Snap!
The dense sounds of impact were like a torrential downpour hitting banana leaves, continuous and relentless. Each strike of the whip contained the power to split mountains and shatter rocks, but no matter how Muzan changed the angle or increased the power, all the attacks stopped outside the invisible barrier around Moyu, unable to advance an inch. Moyu didn't even move his feet, but just quietly "watched" Muzan squander his power.
"Is all you can do is hide in your shell?!" Muzan's anger intensified as he Muzan to break through the defenses. His clothes tore open on his back, and nine thinner, dark purple whips, each about four meters long, suddenly shot out! These whips were faster than daggers, moving like venomous snakes emerging from their holes, silently stabbing towards Moyu. The tips of the whips were sharp, carrying his deadly blood, and once they struck, they would be enough to destroy all of the opponent's cells in an instant.
Nine purple shadows merged into the sky full of whip shadows, and the density and strangeness of the attacks soared once again.
Moyu finally moved. He didn't dodge, but instead raised his left hand.
"Spell sequence -- "Azure"."
Buzz!
A pale blue dot the size of a ping-pong ball appeared in front of his palm. The next moment, a terrifying gravitational force erupted! Not targeting Muzan's main body, but rather the incoming attacks.
Whoosh!
The originally treacherous trajectories of the spiked whip and the tube whip were twisted and deviated by this sudden and powerful gravitational pull, involuntarily drawn towards that dark blue light! Even Muzan himself felt a forward pulling force and had to increase his strength to stabilize his lower body.
Several whip tips that couldn't dodge in time touched the gravitational core of "Azure" and were instantly crushed and destroyed by the power that distorted space! Although the whips could regenerate quickly, this brief setback caused Muzan's attack to pause for a moment.
"Muzan magic!" Muzan cursed, decisively retracting his damaged whip and thorn whip. Realizing that ranged attacks seemed ineffective, he decided to crush him in close combat! His leg muscles swelled, the ground beneath his feet exploded, and his figure transformed into a black lightning bolt, rushing straight at Moyu! At the same time, his legs mutated, and eight whips, each over seven meters long and moving at an even faster speed, shot out like scorpion tails, accompanied by sonic booms tearing through the air, arriving faster than he could and stabbing towards Moyu! These were the fastest attacking organs on his body!
Faced with this all-around, extreme attack in speed and power, Moyu decided to play along.
The moment the Azure Star was drawn from its sheath, the blade transformed into a blazing crimson— the Red Nichirin Blade! At the same time, a barely perceptible layer of Azure light enveloped the blade, an enhancement from Azure's gravitational pull.
"Azure Flow Breathing - Second Form - Mirror Dissection."
With each strike and parry, Cangxing precisely targeted the most vital points or structural weaknesses of the whip and thorns. The Azure Star flashed like a mirror, reflecting the trajectories of countless attacks and dissecting and dismantling them one by one.
Clang! Clang! Sizzle!
The sounds of metal clashing and energy Annihilation rang out in rapid succession. Moyu's figure moved within a small space, his Red Nichirin Blade transforming into streaks of red light, blocking, deflecting, and even severing all Muzan Muzan's storm-like attacks! Occasionally Muzan's blood would splatter onto the Limitless Technique, but it was isolated and slid off by the infinitely extending spatial distance, unable to touch Moyu in the slightest.
"How is this possible?! My attacks were completely..." Muzan grew increasingly alarmed as the fight progressed. He could sense that Moyu's strength and speed might not have completely overwhelmed him, but it seemed as if he could see through everything about him! Every attack was predicted, every change of move was countered. This sense of powerlessness, this feeling of being completely seen through, reminded him of that nightmarish red-haired swordsman!
"Damn it!" Muzan completely mad, holding nothing back. His body began to undergo even more terrifying changes. His human form gradually disappeared, and his limbs and lower body were covered in boiling blood and thick hair. Countless huge mouths with sharp teeth grew from his body, emitting ear-piercing howls. He had become the true progenitor of demons—a twisted monster that sought immortality!
"Blood Demon Art: Black Blood Brambles!"
Countless black thorns, hard as iron and formed from his congealed blood, erupted and lashed outwards from him! Each thorn was as hard as Nichirin Blade, covering an extremely wide area and attacking all space indiscriminately!
At the same time, all the spiked whips and tube whips on his body joined the attack with even greater ferocity! The entire battlefield was instantly engulfed by a storm of death!
Moyu remained composed, combining Azure Flow Breathing with the Limitless Technique. Sometimes he used "Mirror Dissection" to precisely dismantle key attacks, and sometimes he used the spiraling force of "Vortex Slash" to deflect area attacks. He was like a reef in a stormy sea, remaining unmoved no matter how fierce the attack.
The battle lasted for several minutes, Muzan's offensive showed no signs of abating; on the contrary, it became even more ferocious due to his rage. However, his inner anxiety grew stronger. He discovered that the potion he thought had been broken down seemed... to be working again? No, not the same as before; it had changed!
An unprecedented sense of weakness spread quietly like a tide. It wasn't physical pain, but... the loss of vitality? He felt his cell activity declining; although the regeneration rate was still fast, there was a faint sense of stagnation.
"What happened?!" Muzan retreated a distance, looking inward with shock and uncertainty. "Tamayo's medicine... wasn't it already broken down by me?!"
Just then, Moyu's calm voice rang out, answering his doubts. "It seems that Tamayo's potion is more potent than you thought. Once the Demon Transformation Medicine is forcibly broken down, it will transform into a powerful Aging potion. Muzan, your efforts to break down the potion have actually accelerated its effects."
"What?!" Muzan was struck Muzan, his crimson pupils revealing unbelievable fear for the first time! "Aging?! No! This is impossible! I am the most perfect being!!"
He could clearly feel his life force draining away at Aging alarming rate of fifty years per minute! Although this wouldn't be immediately fatal for someone with his long lifespan, this clear awareness of his weakening was a more agonizing torment than any physical injury, given his extreme fear of death!
"Tamayo!! You bitch!!" Muzan roared Muzan, his voice hoarse and distorted due to the change in his form. He was completely panicked, and his millennia-old caution and fear of death took over.
"Nakime! Quick! Teleport me away!" He urgently commanded the controller of the Infinity Castle through their bloodline connection. He had to leave this place first and find a safe place to resolve the abnormality within his body!
However, the spatial teleportation he was waiting for did not arrive; instead, he was met with Moyu raising his right index finger.
"Trying to escape now? Too late."
Moyu's six eyes had already locked onto the female ghost holding the biwa, hidden deep within the complex structure of the Infinity Castle. The moment Nakime contacted Muzan, Moyu made his move.
"Spell Reversal - 'Her'."
A dark red beam of energy, like a meteor tearing through the night sky, burst forth from Moyu's fingertips! It wasn't aimed at Muzan, but rather pierced through the layers of the Infinity Castle structure, heading straight for a specific coordinate in the distance!
"No~!" Muzan sensed the target of the attack and let out a roar of shock and anger.
But it was too late.
In the distance, a brief, abruptly cut-off note came from a pipa string, followed by a faint hissing sound as something was Annihilation.
The shared vision through the Blood Demon Art was instantly severed. Muzan sensed that the bloodline connection between him and Nakime... was broken!
Nakime, the controller of the Infinity Castle, was precisely Annihilation by Moyu from a distance of over a thousand meters! The entire area where she was located was also reduced to nothingness.
"Damn it! Damn it!!" Muzan was filled Muzan shock and rage, almost going mad. With Nakime dead, the Infinity Castle lost its control core and began to shake violently. The surrounding walls and ceiling groaned under the strain, and the massive wooden structure began to crack and collapse!
He had to escape this collapsing cage immediately! Muzan made his most instinctive decision in an instant: split and escape! This was his ultimate trump card to save his life when he was severely Yoriichi Tsugikuni!
"Splitter!" He frantically channeled his power, attempting to split his body into 1,800 pieces!
However, the next moment, the expression on his face froze, turning into extreme terror!
The attempt to split... failed!
A powerful force of resistance emanated from the deepest part of his body, firmly locking away his instinct to split apart! It was another ingredient in Tamayo's potion, Division Inhibition drug! At the same time as the Aging drug took effect, the effects of this drug also became fully apparent, cutting off his last path to survival!
"How could this be... No! I can't die! How can I die! I am the most perfect being!!" Muzan screamed in despair and madness. The Infinity Castle was collapsing, and their escape route was cut off.
"Hold on. As long as I can drag this out until the Infinity Castle collapses and traps this human underneath, I'll still have a chance to escape." The Aging and fragmentation blockage within his body continued to take effect... The fear of a thousand years completely overwhelmed him at this moment, but Muzan still held onto hope!
The instinct for survival overwhelmed everything! His body underwent another dramatic transformation, his flesh and blood proliferating and twisting wildly, ultimately forming a gigantic image of a stillborn infant curled up in its mother's womb! This was the final defensive form he instinctively sought in his desperate situation— the Dead Infant Form! He attempted to rely on the infinite proliferation of his flesh to withstand the devastating attack and fight for a sliver of hope!
At the same time, he mobilized all his remaining strength, preparing to unleash his final Blood Demon Art, unleashing a devastating shockwave centered on himself to disrupt his opponent and make a last-ditch effort!
But Moyu gave him no more chances.
The Infinity Castle was on the verge of collapse, and its massive structure began to crash down from above. Moyu could sense that if the Infinity Castle completely collapsed, although it wouldn't harm him, being buried alive would still be a troublesome matter, and it might also scatter Muzan's remains, creating further complications.
"It's time to end this, Muzan."
Moyu raised both hands, forming a unique hand gesture in front of her chest. The index and middle fingers of her right hand were joined together, while her left hand loosely grasped her right wrist.
"Virtual style-""."
As his deep voice rang out, the energy in the world instantly surged!
First, in front of his joined fingertips, a deep blue energy sphere, as profound as the cosmic starry sky and representing "negative infinity"—"Azure"—was compressed and condensed to the extreme. Space around it contracted and collapsed violently inward, as if even light was about to be swallowed up.
Immediately afterwards, a layer of molten lava-like, crimson energy spheres—representing "positive infinity"—emerged from the outer edge of this "Azure" sphere, instantly enveloping it! A powerful repulsive force began to surge, violently clashing with the internal gravity.
Red and blue, attraction and repulsion, convergence and divergence—two absolutely contradictory energy spheres, representing infinite vectors, are forcibly overlapped at zero distance!
The imagined energy cancellation did not occur. Instead, in this extreme conflict and paradox, a kind of "hypothetical" quality that transcends common sense was born!
Visually, the red and blue energies reacted violently, fused, and twisted, ultimately transforming into an extremely eerie and unstable dark purple. This dark purple energy body was not a stable sphere, but rather an entity that constantly emitted irregular, lightning-like energy pulses, its form wildly twisting and changing between spheres, prisms, and vortices! The light it emitted was filled with an aura of destruction and annihilation, and the surrounding space groaned under its strain, trembling and distorting violently, as if it were about to shatter completely at any moment!
Moyu pointed his fingertip at the infant-like monster in the distance that was frantically proliferating its flesh and blood.
The next moment, he unleashed this hypothetical mass, a fusion of contradiction and destruction, as a massive dark purple beam of light!
The speed of "Zi" is not very fast, but wherever it passes, all matter, energy, and even space itself dissolve and dissipate silently, like a piece of salt thrown into water, instantly turning into nothingness! There is no explosion, no shock wave, only the most thorough... Annihilation!
The beam shot straight at the core of Muzan's final form.
The infant, Muzan of Muzan, seemed to sense the ultimate threat, letting out a sharp, piercing, inhuman howl as it desperately proliferated its flesh and blood in an attempt to block it. But before "Zi," all resistance was futile. The proliferating flesh and blood vanished the instant it came into contact with the dark purple beam of light, just like pencil marks erased by an eraser.
The beam of light pierced through the infant's enormous body without hindrance, continuing forward and Annihilation everything in its path, including large sections of the Infinity Castle behind it! Leaving behind a massive chasm over ten meters wide, bottomless, and with mirror-like smooth edges!
Muzan, who was directly hit by "Zi,"... disappeared.
It wasn't shattered, nor vaporized, but utterly disintegrated and Annihilation at the atomic level. Along with his five brains, seven hearts, and all possible divisions, they were reduced to the most basic particles and vanished into nothingness under this ultimate blow.
The thousand-year-old Demon King, Muzan Kibutsuji, has fallen completely here.
Almost simultaneously with Muzan, the Infinity Castle, having lost the support of Nakime's power, began to collapse at an accelerated pace! The massive wooden structure collapsed like a landslide!
Moyu withdrew his hand, slightly panting. The "Zi" technique was extremely taxing, even for him. He looked up at the darkness pressing down from above.
Without hesitation, he raised his hand again, pointing upwards.
"Virtual style-""."
Another dark purple beam of destruction shot into the sky, Annihilation the layers of the Infinity Castle structure above and creating a massive passage leading to an unknown direction.
Moyu's feet moved slightly, and Azure energy flowed around his body.
"Azure."
The next moment, his figure transformed into a streak of light, rushing upwards at a speed exceeding the speed of sound along the passage opened up by "Zi," leaving the completely collapsed ruins of the Infinity Castle far behind in the endless darkness.
