Feeling the power within his body threatening to burst his blood vessels, the newly awakened demon Tanjiro... floated away.
Looking at the crimson Heat Haze swirling around his fingertips, he grinned with a wild and tyrannical smile.
The feeling was like a whale who just registered for a game and immediately spent 100 million, thinking they could wipe out the entire server with a single strike.
"Is this... the power of the gods?"
Tanjiro's blood-red vertical pupils narrowed slightly, his eyes revealing an arrogant disdain for all living beings.
He even felt that Muzan Kibutsuji, who had previously only used him as a henchman, was simply a short-sighted and low-level reptile.
Overcome the sunlight, awaken the Heat Haze, and possess absolute power surpassing that of the Upper Rank!
Now, he is the sole ruler of this world!
"Hey, you human swordsman over there."
Tanjiro tilted his head slightly, looking contemptuously at Giyu Tomioka a hundred meters away, his expression full of mockery:
"Sun Breathing, Red Nichirin Blade, even that laughable sun in the sky—none of them work on me! What do you have to fight me with?!"
Faced with this delusional, overbearing rant.
A hint of disdain for someone mentally challenged appeared on Giyu Tomioka's perpetually icy face.
"Has this kid's brain been fried?"
Indeed, overcoming sunlight means he has become Perfect Lifeform, impervious to the scorching heat of the Red Nichirin Blade.
But--!
In this world, even if you are a god, you still have to abide by the most basic law of conservation of energy!
"The health bar may be infinitely long, but the mana bar will eventually run out, right?"
If one attempt doesn't kill it, then try ten!
If you can't kill it ten times, then kill it a hundred times, a thousand times, ten thousand times!
Once all the energy in your body is completely drained, even the Creator would have to obediently lie on the ground like a dead dog that can't move!
With that thought, Giyu raised the dark blue Nichirin Blade in his hand.
You talk too much nonsense.
A cold glint flashed in Giyu's deep blue eyes. "Since you consider yourself a god, I'll take responsibility for kicking you off your pedestal."
"Arrogant insect! Die!!"
Giyu's nonchalant attitude completely enraged Tanjiro, who swung his right hand violently!
"Blood Demon Art: Heat Haze - Bursting Red Ball!"
A blood-red fireball the size of a house, carrying intense heat that distorted the air, crashed down like a meteorite towards Giyu's face!
Where the fireball passed, even the frozen ground was burned into lava.
Faced with this devastating blow, Giyu Yong did not budge an inch.
He gently stroked the knife handle with his thumb, and his breathing became long and deep.
"Water Breathing - First Form-- "
The azure water suddenly converged at the blade, as tranquil as an autumn moon over a calm lake, yet containing an unstoppable force capable of stopping the flow.
"Water Surface Slash!!"
A horizontal blue blade of light cleanly and decisively sliced into the giant red fireball!
"Sizzle--!"
The seemingly indestructible Heat Haze was smoothly cleaved in two the moment it touched the azure blade!
The two fireballs grazed past Giyu's sides and exploded with a bang in the snow behind him.
"What?!"
Tanjiro's smug smile froze on his face.
His confidence, which had just reached its peak, was shattered by this single blow, leaving a huge question mark.
That's impossible!
That's the Heat Haze! It can even melt frozen ground!
How could it be sliced open by such a simple Water Breathing?!
"You bastard! Don't get too cocky!"
Enraged, Tanjiro slammed his legs into the ground, transforming into a red blur as he closed the distance.
"If I can't hit you from a distance, I'll smash you into mincemeat!"
Blood-red flames enveloped Tanjiro's arms.
His body, enhanced to the [Super Hashira] level by demon blood, was now like a raging humanoid pile driver!
"Boom! Boom! Boom!"
Tanjiro's fists, carrying explosive force, rained down on Giyu like a storm!
Every punch he threw carried the power to shatter a small hill!
However, this seemingly invincible close-combat suppression was full of flaws in the eyes of Giyu Tomioka.
"Only strength, no skill whatsoever."
Giyu opens up Transparent World!!
Tanjiro's every move looked like a movie scene slowed down ten times.
"Water Breathing - Third Form - Flowing Dance!"
Giyu's figure transformed into afterimages as light and graceful as water.
The Nichirin Blade in his hand created a soft blue splash as it precisely met Tanjiro's powerful punch!
Water can extinguish fire, and it can also deflect force!
Whenever Tanjiro's fist was about to strike Giyu, the light blue blade would cling tightly to his arm, diverting the devastating force along the blade and finally sliding into empty space.
"Damn it! You slippery eel! Why don't you fight me head-on!"
Tanjiro was furious. He felt like a bull thrashing about in the water, every punch landing on cotton. The frustration was driving him crazy.
"Since you enjoy direct confrontation so much, I'll grant your wish."
Giyu's eyes were sharp as knives.
"Water Breathing - Fourth Form - Striking Tide!"
The continuous flashes of sword light erupted like a tsunami!
"Pfft--!"
Tanjiro's right arm, still blazing with intense Heat Haze, was severed cleanly at the root by the deep blue blade!
Dark red demon blood sprayed out!
"Ouch! My hand!"
Tanjiro cried out in pain, relying on his abnormal regenerative abilities, he gritted his teeth and urged his demon blood to flow.
"It'll grow back in the blink of an eye! No matter how many times you cut it off, it won't help!"
"Pfft!"
Just as the granulation tissue began to wriggle and take shape at the cut, and a brand-new right arm was only halfway out, a second, azure blade of light mercilessly slashed down again!
The newly formed thigh leg is broken!
My newly grown left hand is severed!
The body that attempted a sneak attack was severed in half!
In just two minutes.
The entire Mount Kumotori has become a scene of one-sided and inhumane bullying!
Giyu Tomioka transformed into an emotionless machine, his movements fluid and precise, each strike landing precisely on Tanjiro's newly regenerated limbs.
For Tanjiro, who had just gained consciousness and believed himself to be the master of the world, this battle was an unreasonable nightmare!
"Pfft!"
His right leg was cut off for the 130th time.
"What kind of monster is this?!"
Tanjiro's heart collapsed and roared.
Why didn't his sword-swinging speed slow down at all?
Why didn't he break a sweat?
"... How much energy does he actually have left?!"
Tanjiro was panting heavily, his forehead covered in a fine layer of cold sweat.
His once-proud super-fast regeneration was now showing obvious signs of slowing down!
The granulation tissue moved at a slower and slower pace, and the temperature of the Heat Haze) began to drop sharply.
Tanjiro is undoubtedly an unreasonable "overpowered" character!!
But today he encountered Giyu Tomioka!
When a newbie who spends a lot of money encounters a max-level, hardcore player, there's only one outcome: they'll be comboed until they question their existence!
"Huff... huff..."
Tanjiro retreated several hundred meters in a disheveled manner, creating distance between them.
With his hands on his knees, a rare glimpse of fear flashed in his blood-red vertical pupils.
"What's wrong, Tanjiro?!"
Giyu held his Nichirin Blade, which remained spotless and untouched by blood, with one hand, his demeanor unchanged.
"Your stamina seems to be almost depleted; your regeneration rate is a full 0.5 seconds slower than before."
"Is this your limit? It seems you're not all that great after all."
"Shut up!!"
This condescending disdain completely shattered Tanjiro's last remaining pride!
He is an ultimate being, surpassing Muzan! How could he be so humiliated by a human here!
I'm going to burn you to ashes! Not even a trace will remain!
Tanjiro's eyes were almost bleeding from extreme rage.
"Boom--!"
An unprecedented heatwave erupted from Tanjiro's body!
The power was so immense that even the hard rock beneath his feet melted into boiling magma!
Crimson flames shot into the sky, reaching straight into the clouds and dyeing the entire Mount Kumotori apocalyptic crimson.
"This is all my power! Take this and die!!"
Tanjiro raised his hands, and the towering sea of blood-red flames began to spin and compress wildly, eventually condensing in mid-air into a giant dragon a hundred meters long, its entire body burning with raging Heat Haze!
Each scale of the dragon was made of extreme flames, and the surrounding air emitted a shrill scream under this heat wave!
"Blood Demon Art: Heat Haze-- "
Tanjiro let out a hysterical roar from his throat.
"Burning Crimson Dragon!!"
A hundred-meter-long crimson fire dragon let out a deafening roar, swooping down from the heavens with an aura of annihilation, its target Giyu Tomioka!
It seemed as if the fire dragon had sucked all the oxygen from the mountaintop.
Faced with this world-destroying attack, a serious glint finally appeared on Giyu Tomioka's perpetually icy face.
"It is indeed very large, and the temperature is also very high."
Giyu took a deep breath of the scorching air, his lungs roaring like war drums.
"However, a chaotic accumulation of energy is ultimately just an empty shell!"
Giyu gripped the hilt of the sword with both hands, his body muscles tensed to a degree beyond human limits!
The Transparent World, combined with Heaven-Defying Comprehension, is operating at its peak at this moment!
"Water Breathing - Tenth Form-- "
Giyu's body began to spin rapidly in place!
With each rotation, a layer of azure water-wave light is superimposed in the air!
One floor... ten floors... a hundred floors!
As Giyu's spinning speed skyrocketed, the water sword energy around him also transformed into a giant water dragon soaring into the sky!
"Constant Flux!"
This water dragon, formed from deep blue sword light, was no less large than the blood-red fire dragon, and even surpassed it in terms of imposing aura!
The azure water dragon let out a clear, resounding roar that pierced the clouds, and charged fiercely towards the raging crimson dragon descending from the sky!
Red and blue!
Fire and water!
Two colossal dragons, each a hundred meters long, representing the pinnacle of human and demonic power, collided with a deafening roar above the Mount Kumotori!
"Boom--!"
A violent shockwave swept across the entire mountaintop like a Category 12 hurricane!
Snow and molten lava swirled wildly in the sky, creating a spectacular red and blue storm!
Right at the heart of this devastating storm,
"Roar--!"
With its infinitely stacked kinetic energy from [Constant Flux], the Deep Blue Water Dragon displays an absolute domineering posture!
Its dragon claw, formed from thousands of sword energies, pressed down on the fire dragon's head!
Then the water dragon opened its enormous, abyssal maw and bit down hard, crushing the blood-red fire dragon's neck!
"Sizzle--!"
The blazing Heat Haze was extinguished and shattered by this unparalleled deep blue torrent, as if facing annihilation, and finally turned into countless red specks of light scattered across the sky!
"No... this can't be..."
Watching his most powerful attack, which he had poured all his strength into, being bitten to pieces, Tanjiro let out a desperate murmur.
The storm gradually subsided.
The Mount Kumotori returned to tranquility, but the once flat mountaintop had been completely sheared away by the collision.
Dust settled in the air.
Giyu Tomioka stood tall amidst the ruins, holding Nichirin Blade in one hand.
The unusual-colored feather robe she wore fluttered gently in the lingering wind.
What's truly astonishing is that, despite such a collision, this pinnacle of human combat prowess remained completely untouched by blood or dust!
... Still so calm and composed!!
Meanwhile, in a deep pit dozens of meters away, Tanjiro collapsed to the ground.
The demon's body was now incomplete, its energy completely drained, leaving it without even the strength to repair a minor wound.
Those once arrogant and domineering blood-red vertical pupils now lost all focus, and the whites of their eyes rolled upwards.
"With such meager physical strength, you dare to try and become a god?"
Giyu looked down at Tanjiro had completely lost consciousness!
"Click--!"
With a crisp sound, the Nichirin Blade returned steadily to its sheath.
P. S.: For the sake of visual effect, I have raised the overall combat power of almost all the Demon Slayer characters by a level!
Muzan has received a buff and will be given multiple Blood Demon Arts!
He's the Demon King after all, he needs to have some dignity! The original story was terrible, he was still low on health in the final battle!
Finally, let's briefly discuss the issue of combat power!
Combat strength:
Heavenly King tier – Giyu Tomioka, Yoriichi Tsugikuni!
T0 tier - Kibutsuji Muzan!
Quasi-T0 tier – Tanjiro the Demon!
