The transformation spirals out of control, the Water Hashira rushes to the rescue!

"Pfft--!"

Muzan Kibutsuji's once long and elegant index finger had now transformed into an extremely sharp spike, which pierced deeply into the center of Tanjiro Kamado's forehead!

Being so terrified by a charcoal-selling brat that he exploded and split apart on the spot—this utter humiliation had completely driven this thousand-year-old progenitor of demons to utter madness!

"Gurgle..."

Accompanied by a nauseating sound of liquid flowing,

The Demon King's Blood, containing violent and Muzan power, flowed wildly from Muzan's fingertips into Tanjiro's body!

"Ahhh--!"

A heart-wrenching scream instantly erupted in front of the cabin!

Tanjiro felt as if an erupting volcano had been forcibly shoved into his brain!

That kind of pain is simply beyond the capacity of the human nervous system to endure.

He felt as if every inch of his blood vessels was being repeatedly flushed, and every cell was being forcibly torn apart and reorganized!

His skin began to turn an unnatural pale white, and in his once clear, wine-red eyes, blood vessels spread wildly like a spider web.

Scream! Scream to your heart's content!

Muzan's face was etched with a Muzan, maniacal laugh, and his crimson vertical pupils were filled with sadistic pleasure.

I'm going to crush your weak human body completely! I'll let you experience what true despair is!

The piercing screams pierced through the raging wind and snow, reaching directly into the tightly closed cabin at the back.

"Elder brother!!"

"Tanjiro!!"

Accompanied by several terrified screams, the wooden door was suddenly pushed open from the inside.

Kie Kamado rushed out with disheveled hair, not even having time to put on her coat.

Behind her, Takeo gripped a thick wooden stick he usually used for starting fires tightly, while Nezuko, Delia, and Shigeru followed behind, their faces streaked with tears.

When they rushed outside and saw what was happening in the snow, everyone's brains went blank for a moment.

Amidst the swirling snowflakes, a terrifying man in a tattered suit is poking Tanjiro's forehead with his fingers.

Their eldest son, who was always gentle and always protected his family, was now kneeling painfully in the snow, his body undergoing some terrible transformation!

"Let go of my brother! You monster!!"

The usually arrogant Takeo's eyes turned red at this moment.

Without the slightest hesitation, he raised the fire poker in his hand and charged towards Muzan like a mad calf!

"Don't hurt my child!"

Kie, also fiercely protective of her child, grabbed a broom from the doorway and fearlessly rushed forward.

"A bunch of noisy ants."

Muzan merely turned his head slightly, his crimson vertical pupils casting an extremely contemptuous glance at the Kamado Family rushing towards him.

Just one look!

A terrifying, suffocating pressure instantly slammed down on Kie and the others!

Thump! Thump!

The fire poker in Takeo's hand fell directly into the snow, his legs buckled uncontrollably, and he collapsed heavily to his knees.

Extreme fear directly froze their central nervous system.

Muzan looked at the mortals frozen in place, their eyes filled with despair, and a sinister smile curled at the corner of his mouth.

Of course, he could easily chop those eyesores into mincemeat right now with a flick of his finger.

But that would be too boring!

You should feel honored.

Muzan spoke in a condescending, condescending tone.

"Once I transform this arrogant brat into a demon, I will issue him his first command as a demon."

Muzan's voice was filled with a chilling malice:

"That is... to make him personally tear you, his most beloved family members, into pieces and swallow you whole!"

"Let him use this body that protects you to taste your flesh and blood!"

"Haha, just imagining that scene makes me feel like it's the greatest blessing I can give you!"

Upon hearing these devilish words, Kie's tears flowed uncontrollably, and Nezuko desperately tried to break free from the oppressive restraints, but the power of mortals was far too insignificant before the Demon King.

"No... absolutely... no!!"

Just then, Tanjiro, who was being forcibly injected with demon blood, managed to squeeze out a few words through his teeth amidst extreme pain!

A chillingly tenacious will erupted from his eyes, which were gradually transforming into beastly pupils!

"I absolutely refuse to become a monster who hurts my family!!"

Tanjiro roared madly in his heart.

He strained with all his might, trying to regain control of his body, even attempting to pull the finger stuck between his eyebrows with his own hands!

"You dare to resist? It's like an ant trying to shake a tree!"

Muzan snorted Muzan, deciding not to waste any more time, and directly increased the output of his demon blood!

Based on Muzan's thousand years of experience in "creating demons," it doesn't require much blood to transform an ordinary human into a demon.

Those drooling, man-eating monsters on the street can be easily transformed without even needing one ten-thousandth of his demon blood.

Even those Lower Rank that he assigned numbers to could only withstand a maximum of one percent of the blood.

One more drop, and those useless cells would collapse and dissolve on the spot because they couldn't withstand this domineering force!

Even the biggest nightmare the Demon Slayer Corps currently faces, his top-paid subordinate— Upper Rank One Kokushibo!

Muzan only granted him one-fifth of the demon blood, and that guy twitched and groaned on the ground for three days and three nights before he could barely complete the reconstruction of his body!

However, when Muzan continuously pumped demon blood into Tanjiro's body,

One minute has passed!!

Two minutes have passed!!

The Muzan sneer on Muzan's face gradually froze.

His brows furrowed slightly, and a hint of undisguised astonishment flashed in his eyes.

"This... how is this possible?!"

This charcoal-selling brat's body was like a bottomless black hole!

In less than two minutes, this kid had already sucked away a full one percent of his ghost blood like a water pump!

Moreover, instead of collapsing due to the power overload, the kid's cells were greedily devouring his blood!

One percent!

This is a massive amount of health that can instantly create a Lower Rank Demon!

This kid actually digested it completely in less than two minutes?!

Such terrifying absorption efficiency and cell compatibility are something that even Kokushibo, that old employee, could never achieve back then, let alone those useless Lower Rank!

Muzan looked at Tanjiro, who was kneeling in the snow and still resisting frantically, a thought suddenly flashed through his mind.

What does that mean?

This can only prove one thing!

This kid's potential after turning into a ghost is ridiculously high!

It even far surpasses Kokushibo!

Upon thinking of this, Muzan's anger at being scared into self-destructing by the half-baked Sun Breathing was instantly swept away by a surge of fervent excitement!

"We made a killing! This time we absolutely made a fortune!"

Muzan's seven hearts were so excited at that moment they practically wanted to tap dance!

Muzan had always felt that the fighting strength of his Twelve Kizuki was somewhat lacking.

Especially when faced with the suddenly appearing dead Giyu Tomioka, Muzan felt that all his henchmen were useless good-for-nothings!

But now, an SSR-level embryo that's even better than Kokushibo has actually delivered itself to our doorstep!

What's even more incredible is that this kid has a face almost exactly like Yoriichi Tsugikuni's, and wears the same sunflower earrings!

"Haha! This is truly heaven's help!"

Muzan help but burst into wild laughter, his eyes blazing with greed and ambition.

"If I can completely mold this brat into my strongest weapon... no! The title of Upper Rank One is no longer worthy of him! I will make him the unprecedented Upper Rank Zero!"

"Then, let him go and tear that bastard named Giyu Tomioka into strips of flesh!"

"... Let that damned expressionless man taste what it's like to be rubbed into the ground by the successor of the Sun Breathing!"

Thinking of that bright future, Muzan no longer hesitated to spend money.

"Go ahead and suck! Since you can suck, I'll let you suck to your heart's content!"

Muzan gritted his teeth and directly released the restrictions on his own blood!

The purest Demon King's Blood was poured into Tanjiro's body like water, without any regard for cost!

This is an unprecedented project to create a god!

Time flowed slowly through this icy, snowy landscape.

The wind and snow seemed to have subsided somewhat, but the oppressive feeling in the air grew heavier.

Tanjiro's screams gradually subsided.

Sharp fangs began to grow from his mouth.

The dark red scar on his forehead gradually transformed into sinister flame patterns.

His once clear eyes had now completely transformed into the vertical pupils of a wild beast, and the human reason within them was being stripped away and devoured bit by bit.

"No... no..."

Deep within his mind, Tanjiro clung to the last vestige of clarity, frantically pounding on the closing gate of darkness in his spiritual world.

Before we knew it, a faint tinge of dawn was beginning to appear on the horizon.

Dawn is approaching.

At this moment, Muzan Kibutsuji's forehead was covered in a fine layer of cold sweat.

His usually handsome but pale face was now as white as a sheet of paper, and even his breathing had become somewhat heavy.

"How much more is this kid going to take...?"

Muzan inwardly groaned.

He spared no expense tonight in creating this unprecedentedly powerful henchman!

The little devil actually drained nearly half of the ghost blood reserves in his body within a few hours!

If it weren't for the fact that he was the progenitor of demons and his blood regeneration speed was astonishingly fast, he probably would have been sucked dry by this charcoal-selling brat tonight!

"However, it was all worth it."

Muzan sensed the terrifying power emanating from Tanjiro's body, a power that even made him feel a little uneasy, and once again, a satisfied smile, typical of capitalists, appeared on his lips.

"Almost done!!"

"As soon as dawn breaks, I will return to Infinity Castle with this most perfect work of art!!"

"The good days of that expressionless guy are coming to an end..."

Muzan was engrossed in his own wonderful fantasy.

However, at that very moment...

"Boom--!"

A terrifying sonic boom, like thunder from the heavens, exploded without warning from the mountainside of Mount Kumotori!

The sound was so loud that it caused the snow on the surrounding trees to fall in a rustling sound!

Muzan turned his head, and his crimson vertical pupils instantly shrank to the size of pinpoints!

On the distant snow-covered plains, an unbelievable scene unfolded!

Instead of seeing anyone running, I saw a deep blue gale!

This gale, moving at a terrifying speed that completely surpasses the speed of sound, glided low over the snow at an almost perfectly parallel angle to the ground!

The snow along the way was instantly pushed aside by this violent kinetic energy, forming two snow waves several meters high on either side of the gale!

"What the hell is that speed?!"

Muzan's brain didn't even have time to analyze the identity of the person.

The blue gale had already covered a distance of over a thousand meters in a fraction of a second, and had fiercely reached the front of the cabin!

The strong winds suddenly stopped!

A cold-looking young man wearing a distinctively colored haori landed steadily on the snow Muzan than thirty meters away from Muzan, as if a demon god had descended from the heavens!

The person who arrived was none other than Giyu Tomioka, the Water Hashira who had sped to the limit after receiving the message from the Kasugai Crow!

Giyu's feet had just touched the ground, and he hadn't even caught his breath.

His deep blue eyes instantly locked onto Muzan, who was sticking his finger between Tanjiro's eyebrows.

"Even after rushing so hard, am I still too late?!"

Without any hesitation.

Giyu forcefully pushed the hilt away with his thumb!

His right hand instantly gripped the hilt of the knife, and the muscles throughout his body contracted wildly at a frequency that exceeded human limits!

"Total Concentration-- "

Giyu's voice was deep and cold, as if it came from the deepest hell.

"Moon Breathing - First Form-- "

"Zheng--!"

The Nichirin Blade was drawn with a fierce roar!

"--Sei Evening Palace!!"

With the gesture of Giyu swinging his sword.

The entire night seemed to be paused for a moment.

A crescent-shaped sword aura, over ten meters long and displaying a dazzling silver-white color, tore through the air without warning!

The sword energy swept through the air, leaving behind countless tiny blades of wind in the space along its path!

"This... how is this possible?!"

Muzan's pupils instantly contracted to their limit, and a hysterical scream erupted from within!

Faced with the terrifying sword energy coming straight at him, Muzan felt the threat of death!

He wanted to pull out the finger stuck between Tanjiro's eyebrows to defend himself.

But it was too fast!

The speed of this sword energy has completely exceeded Muzan's current nerve reaction limit!

"Sizzle--!"

The silvery-white sword energy grazed Tanjiro's forehead with absolute precision!

Not a single hair on Tanjiro's head was harmed!

But Muzan's right arm, which was stuck between Tanjiro's eyebrows, was instantly severed at the root by this cold sword energy!

"Ahhh--!"

With his arm severed, Muzan let out a painful howl.

His noble Demon King's Blood, sprayed onto the snow.

Muzan, like a frightened wildcat, retreated frantically!

Ten meters!

Thirty meters!

Fifty meters!

Muzan slid for over a hundred meters on the snow, crashing into three thick pine trees before finally regaining his balance!

On the other side...

Giyu Tomioka's figure flashed like a ghost, directly blocking Tanjiro and the Kamado Family.

He casually swung his Nichirin Blade.

"Bang!"

The remaining sword energy carved a terrifying chasm tens of meters long into the snow!

The wind and snow raged over this ravine.

Giyu held a sword in one hand, his red and white haori fluttering in the gale.

He slowly raised his head, his deep, abyss-like blue eyes locking onto the disheveled Muzan Kibutsuji from a distance of over a hundred meters.

For once, Giyu's usually expressionless face showed a rare hint of a cold smile.

"We've finally met again!!"

"Kibutsuji · Muzan!!"
