Muzan stared wide-eyed at the Demon Slayer was relentlessly attacking him.
Even now, he still can't quite understand why he encountered Demon Slayer.
Encountering Demon Slayer is Demon Slayer, but why did it have to be the one I least wanted to encounter right now?
No, I have to go first!!
The thought flashed through his mind, Muzan roared in his head.
" Nakime!!!"
"Zheng..."
A clear, melodious pipa tune echoed across the platform, and an ancient wooden door appeared behind Muzan.
Muzan retreated rapidly while manipulating the blood whip behind him to lash forward, attempting to block the opponent's path.
Seeing this, Teiichi narrowed his eyes slightly and took a deep breath.
" Wind Breathing - Modified - Fifth Form - Gale..."
"A fleeting glimpse!"
Whoosh--!
A blue light suddenly shone on the platform, then, like a nimble dragon, it drew an extremely beautiful trajectory in the air, heading straight for Muzan with Muzan momentum.
The blood whips encountered along the way were all struck open like fragile withered branches by this sharp blue light, scattering in all directions.
As he gazed at the azure light hurtling towards him, Muzan's pupils dilated slightly.
By comparing their speeds, he clearly realized that he couldn't possibly enter the Infinity Castle before Kato Teiichi arrived.
So, should I brave his attacks and run into the Infinity Castle?
But what if he follows them in?
Thanks to the special nature of the Infinity Castle, he was absolutely certain that Nakime could teleport him out of the Infinity Castle and escape from Kato Teiichi!
Can...
The image of the Infinity Castle teetering on the brink of collapse from months ago flashed before Muzan's eyes once more.
Muzan's heart sank.
We absolutely cannot let him go in!
It seems the Demon Slayer Corps has figured out a way to find me. If it weren't for the Infinity Castle, I wouldn't be able to escape if I encountered Kato Teiichi next time!!!
In the blink of an eye, Muzan swiftly swung his claws to meet the blue light.
Clang!
The two colors, blue and red, suddenly collided on the platform.
At the moment of collision, the two figures were abruptly frozen on the platform.
The next moment, an invisible shockwave poured outwards.
The platform floor trembled slightly, sending small pebbles flying into the air before being tossed far away by the force.
After a brief moment of stillness, the two figures began to move wildly again.
Clang! Clang! Clang! Clang!...
A series of crisp, deafening metallic clangs resounded densely on the platform like a torrential downpour, while blue and red lights intertwined wildly on the platform.
Muzan's face was slightly distorted by anger and exertion as he frantically swung his claws to meet the attack.
However, despite his best efforts, the red light was still firmly suppressed by the green light.
If it weren't for the blood whip behind him constantly disrupting Teiichi's attack rhythm, the Nichirin Blade would have already struck him.
Although Teiichi had been intentionally controlling the battlefield throughout the battle, the battlefield continued to expand on the platform like a spreading fire under the intense fighting.
The blood whip, deflected by the Nichirin Blade, carried its remaining force like an out-of-control cannonball, slamming into every corner of the platform.
It could be on the platform floor, on top of the carriages, or on the stone pillars supporting the top of the platform.
Boom! Boom! Boom! Boom!...
The roaring sound echoed continuously on the platform.
At a certain moment, accompanied by an exceptionally loud "boom," another stone pillar supporting the top of the platform was mercilessly smashed in half by the flying blood whip.
The moment the stone pillar broke, the entire platform seemed to shake.
Then, amidst chilling creaking sounds, spiderweb-like cracks rapidly spread across the top of the platform.
After a brief standoff, the lights on the platform ceiling went out like shooting stars, plunging the entire platform into darkness.
Immediately following was the rooftop collapsing with a deafening crash, as huge stones rained down amidst the dust.
Clang!
After the Nichirin Blade clashed with Muzan's claws once more, Teiichi paused his attack slightly.
Glancing at Muzan, who was Muzan rushing backward, Teiichi slightly raised his eyes to look at the huge boulder falling from above.
He raised his sword and swung it.
Swish!
As the Wind Blade swept past, the area around Teiichi's head was instantly cleared, with rocks being Wind Blade in two and sliding to the sides.
However, the remaining stones gradually fell to the ground, and a huge rumbling sound rang out as the stones landed one after another.
Along with the roar, a cloud of dust rose up.
Smoke and dust enveloped the entire platform, obscuring the specific situation on site.
A gentle breeze was blowing across the battlefield...
Teiichi slightly raised his eyes, his gaze quietly fixed ahead, sensing the figure running rapidly away and the door about to open again.
Teiichi quickly ran his hand across the blade.
" Sixth Form: Vibrating Blade!"
The Nichirin Blade vibrated at an extremely high frequency, and the blade turned red at a speed visible to the naked eye.
He held the Nichirin Blade slightly to one side with Teiichi hands, and then...
suck--!
" Wind Breathing - Modified!"
A cold voice came from Muzan, Muzan his body to stiffen slightly.
He stopped abruptly, turned around, raised his hand towards the carriage still next to him, and shouted loudly:
" Kato Teiichi! If you dare come any closer, I'll kill everyone in this carriage!!"
However, the only response he received was a faint, indifferent three-word voice that slowly drifted from the depths of the smoke and dust:
" First Form!"
Muzan's face twisted instantly, his eyes widened, and he roared madly:
"Since you don't care whether they live or die, then let them all die!!!"
Before he Muzan finish speaking, Muzan's right arm, which was pointing towards the carriage, began to swell rapidly at a visible speed, turning into a nauseating mass of flesh and blood in the blink of an eye.
The flesh and blood seemed to possess a life of their own, spreading towards the carriage like a surging tide, slamming against the carriage with an overwhelming force.
Boom!
The giant arm, made of flesh and blood, collided violently with the carriage, and the immense force instantly caused the train to tilt slightly.
Steel and flesh pressed against each other, producing a chilling creaking sound. After a brief standstill, the train finally crashed to the ground with a loud thud.
However, Muzan was not satisfied with this, because there were fewer people at night, and he was closer to the carriage, so he didn't have time to let his arm expand too much before he blasted it, which resulted in his attack only killing two people!
Muzan raised his hand and swung his arm at the train again.
Just then, a streak of azure light flew straight over, completely Muzan Muzan's arm that was hurtling towards the train.
Muzan stared at the approaching blue light in his field of vision, his pupils dilating slightly.
Is this guy even human?
Does he really have no intention of caring about the lives of other people?
Does he even have any morals anymore?
