"The Demon Slayer Corps is deeply grateful for the kindness of the three of you." Kagaya Ubuyashiki spoke first, his gentle voice carrying a heartfelt sincerity. "Since the three of you are willing to lend a hand, we will do everything in our power to cooperate with your actions. Now... how should we hunt down Muzan Kibutsuji?"

He stopped using probing words and instead adopted the lowest possible stance, handing over the initiative to Gu Chuan.

Gu Chuan picked up the tea that Shinobu Kocho had personally served him, took a sip, and calmly said, "Know yourself and know your enemy, and you will never be defeated. Before formulating a specific hunting plan, I need to understand all the information about demons, especially their weaknesses and Muzan Kibutsuji's abilities."

“Please let me explain this,” Shinobu Kocho immediately replied, taking out a scroll from her bosom. The scroll contained a diagram of the cellular structure of a demon, drawn with fine brushstrokes.

"Based on my years of research, the physical structure of ghosts is completely different from that of humans. Their cells possess extremely strong regenerative and mutability, which is why they are immortal."

And the root of all Blood Demon Arts. Its only weakness is sunlight and a specially crafted Nichirin Blade. Because Muzan Kibutsuji's blood is the source of all demons, his cells must possess an activity and power far beyond our imagination…

"The activity of cells is ultimately just a superficial phenomenon."

A cold, slightly arrogant voice abruptly interrupted Shinobu Kocho's explanation.

Everyone looked in the direction of the sound and saw Rin Tohsaka holding a teacup, a hint of intellectual superiority playing on her lips.

“Miss Shinobu, your analysis from a biological perspective is certainly correct, but it’s like only seeing the parts of a machine without understanding the energy core that drives it.”

Rin looked at Shinobu Kocho with her deep blue eyes, her tone like she was lecturing a thirst for knowledge-filled junior, "The essence of these creatures is closer to a cursed life form. Their cells are merely containers for that curse. What truly drives their regeneration is the magic power originating from the root of life, which is the polluted life energy contained in the blood of Muzan that you speak of. And the reason why the Nichirin Blade can kill them is not because of its special material, but because it absorbs the sun's light energy. Light energy contains the purest concept of exorcising magic, which can neutralize and purify that cursed power from its source."

She paused, then threw out a concept that left all the Pillars bewildered: "If you compare a demon's body to a poor-quality magic circuit, then Muzan Kibutsuji is the one and only Od. As long as you don't cut off this Od, no matter how many demons you kill, you're just trimming weeds, and they'll grow back in the spring."

These words were like a door to a new world, suddenly opened before all the people of Yiliuyijiuqijiuxia.

(II) Zhouqi Liuyi 8 Liuyue/Yi Magic Circuit? Root of Life? Concept of Breaking Magic?

These unfamiliar words, each seemingly containing profound truths about the world, made Shinobu Kocho's cell theory based on modern medicine instantly seem somewhat... superficial.

Shinobu's smile froze slightly. Looking at the blonde twin-tailed girl before her, she felt a utter sense of defeat for the first time in her most proficient field of "knowledge." Her proud research had been reduced to a shallow view of "only seeing parts" in the other girl's eyes.

[March 7th]: Wow! Rin-san is amazing! What you said was so profound. Although I didn't quite understand it, it made a lot of sense!

[Alicia]: Hehe, a magician's pride, huh? In her area of ​​expertise, she'll never admit defeat. Miss Shinobu's expression seems a little off?

[Butterfly Dance]: ...Miss Rin's insights have indeed provided me with entirely new perspectives. So...that's how it is.

"Hmph, what's the use of spouting these nonsensical theories?"

A more domineering and disdainful voice completely interrupted Rin's "knowledge showing off".

Esdeath set down her teacup with a soft thud. Her icy blue eyes swept aggressively over Rin and Shinobu, finally settling on Gu Chuan. In those eyes was an undisguised desire for and challenge of the strong.

“Discussing these weak theories is a complete waste of time.” She stood up, her white military uniform appearing even more upright under the light of the Japanese-style room. “Gu Chuan, instead of listening to their theoretical discussions here, how about we have a real combat training exercise?”

"Only in the struggle between life and death can one truly understand their opponent. And the only bond that holds us strong together is always—strength!"

Her words, like a drawn blade, were filled with cold iron-blooded madness and madness, making the temperature in the Japanese-style room seem to drop a few degrees. Rin was speechless, her face full of indignation at being called a "barbarian."

After her initial surprise, Shinobu Kocho regained her impeccable, gentle, and warm smile.

She didn't get involved in their argument, but instead stood up naturally, walked to Gu Chuan's side, and refilled his slightly cooled teacup with piping hot tea.

"Gu Chuan-kun, please have some tea." Her voice was so gentle it seemed to drip with water, and her movements were elegant and skillful, every gesture proclaiming her status as the "mistress." "Miss Esdeath and Miss Rin have come from afar, and must be tired. We can discuss the details of the hunting plan slowly. I will arrange accommodations for everyone, so please be sure to rest well at the Butterfly Mansion."

She smiled, using the gentlest words to skillfully maneuver between the three, defusing the tense atmosphere. But the occasional glances she cast at Rin and Esdeath's retreating figures carried a hint of unfathomable, cunning scrutiny.

One is a knowledgeable and arrogant magician. The other is a battle maniac who believes in absolute power and is filled with a desire for conquest.

What an interesting combination.

However, it won't be so easy for you to take the light away from me.

That night, Butterfly House prepared a private courtyard of the highest standard for the three distinguished guests.

However, this tranquility was destined to be shattered.

At midnight, Esdeath's icy blue eyes suddenly opened in the darkness. She sensed the powerful aura emanating from the neighboring courtyard—a aura as deep as a black hole, both terrifying and captivating. Every cell in her body yearned to collide with that power.

The instinctive desire to conquer the strong has long since overwhelmed everything else.

She silently rolled out of bed, her figure disappearing into the night like a ghost. To her, the Butterfly Mansion's defenses were utterly useless. She easily bypassed all the patrolling Demon Slayer Corps members and sneaked into the courtyard where Gu Chuan was.

There were no lights in the room, only moonlight streaming through the window, casting a cool glow.

Gu Chuan was sitting cross-legged on the tatami mat, meditating with his eyes closed.

Esdeath licked her lips, a hunter's excited yet cruel smile spreading across her face. She made no sound, taking one step at a time, as she approached Gu Chuan.

She wanted to use the most direct and primal method to confirm the man's strength, and then... completely "conquer" him!

However, just as her hand was about to touch Gu Chuan's shoulder—

"—Stop right there! You shameless woman! What do you think you're doing to Gu Chuan?!"

A suppressed, angry shout came from the doorway!

Rin Tohsaka had appeared there at some point. Her large nightgown couldn't conceal the sharp, aura she exuded, like a cat with its fur standing on end.

"Who do we have here? It's you, you little sparrow who only knows how to play with jewels." Esdeath slowly turned around, her smile turning cold and dangerous. "So late, here to check the barrier? Or... you couldn't resist coming for a night raid?"

"What nonsense are you spouting!" Rin's face flushed crimson instantly. She had indeed sensed Esdeath's undisguised, conquering aura, and her internal alarm bells had been ringing. That's why she had rushed over using the excuse that "the protective barrier had been activated." She never expected to actually witness this scene!

"I'm warning you! Stay away from Gu Chuan! He's not someone you can lay a finger on!" Rin held a ruby ​​between her fingers, and magic began to surge.

"Touch?" Esdeath seemed to have heard the biggest joke in the world. "Only the weak are touched. Between the strong, there is only conquest and being conquered! And you don't even have the right to be conquered by me. Get out of my way and don't disturb my communication with my kind."

"You... incurable violent maniac! Combat idiot!"

"A little girl who only knows how to talk."

The air between the two seemed to freeze, thick with tension. A major battle was about to erupt.

At this critical moment.

"Oh, ladies, aren't you resting so late? Are you discussing tomorrow's tactics?"

A voice as gentle as moonlight came from the other end of the corridor.

Shinobu Kocho walked gracefully towards us, carrying a tray with three steaming cups of calming tea and some delicate wagashi (Japanese sweets). Her face wore that ever-present, flawless smile.

She seemed completely oblivious to the tense atmosphere in the room, and said in a concerned tone, "I guessed that Gu Chuanjun might have trouble sleeping because he was thinking about tactics, so I specially prepared some late-night snacks. Would you two ladies like some too?"

She stood at the door with a smile, using the gentlest method to block Esdeath's "attack" and Rin's "interception" from entering.

“Gu Chuan must be tired too,” she said, glancing at Gu Chuan, who hadn’t opened his eyes the entire time. Her voice grew softer. “If there’s anything important, let’s wait until tomorrow and get some rest. After all, we’ll still need the strength of the three of you for the battles to come.”

What a clever tactic of feigning retreat to advance!

Esdeath narrowed her icy blue eyes slightly. She could sense that the woman in front of her, who always seemed to be smiling, possessed a resilience and cunning far beyond what appeared to be on the surface.

Rin was also furious, knowing that she had already lost the upper hand in her actions tonight. Continuing to argue would only make her seem unreasonable.

Finally, Esdeath snorted coldly, withdrawing her terrifying aura, and turned to brush past Rin. As she passed Shinobu, she said coldly in a voice only the two of them could hear, "Don't think you can get anything with such petty tricks. The strong are only attracted to those who are even stronger."

Shinobu's smile remained unchanged, but after Esdeath left, she softly replied, "Is that so? But sometimes, the strongest fortress is precisely the one that is crumbled from within by the gentlest water."

A fierce battleground, filled with the smoke of war, has temporarily come to an end thanks to Shinobu Kocho's skillful intervention.

Inside the room, Gu Chuan finally opened his eyes slowly. Looking at the three girls at the door, each with their own thoughts and unwilling to give in, and feeling the lingering, intense tension in the air, he couldn't help but rub his temples, feeling a bit of a headache.

It seems that before hunting Muzan Kibutsuji, I need to figure out how to deal with... this fire in my backyard.

73. What do you take life for?!

Last night's war without gunfire has temporarily ended in a delicate balance.

The next morning, as the first rays of sunlight pierced through the clouds and bathed the courtyard of the Butterfly House, all the ambiguity and confrontation in the air vanished, replaced by an unprecedented, united, and indomitable fighting spirit.

All nine Pillars of the Demon Slayer Corps have assembled. They hadn't slept all night, but none of them showed any signs of fatigue. On the contrary, they were full of energy and high spirits because of the hope brought by the "sun in the courtyard".

"Gentlemen!" Kyojuro Rengoku's voice boomed like a bell. He surveyed his comrades, his eyes burning with a flame more intense than ever before. "The long-cherished wish of a thousand years is fulfilled today! With the help of the Observer, we will surely sever Muzan Kibutsuji's head and usher in the true dawn!"

"Oh oh oh oh oh!" Shinazugawa Sanemi and the others responded in unison, their momentum unstoppable.

Just as the atmosphere reached its peak, a vibrant yet slightly shy voice made a move that surprised everyone.

"Um... Mr. Gu Chuan!"

Love Pillar Kanroji Mitsuri suddenly ran out of the crowd with her face flushed. To everyone's astonishment, she rushed straight to Gu Chuan and then, with a "thud," knelt down on the ground in a standard dogeza posture!

"Huh?!" Everyone was shocked.

"Please, please marry me!" Kanroji Mitsuri shouted these words with all her might, her eyes closed.

The air froze instantly.

All the pillars stared in disbelief at the scene, even Kagaya Ubuyashiki's smile froze.

[March 7th]: Pfft—! Married?! Miss Koihashi is so direct!

[Alicia]: Oh wow~ This is truly... the boldest and most direct confession ever! I love it!

[Butterfly Dance]: ...Miss Kanroji, you really are 953...as energetic as ever. (laughs)

The atmosphere around Gu Chuan instantly went from frozen to icy.

"You... shameless woman!" Rin Tohsaka was the first to explode, pointing at Kanroji, trembling with anger. "We... we just met and you want to get married?! What... what are you thinking?!"

"Hehe..." Shinobu Kocho was still smiling, but behind her it seemed as if a field of black lilies bloomed. She said in a gentle yet chilling voice, "Miss Kanroji, Mr. Gu Chuan is an important guest of ours. We can't bother him in this way."

Esdeath merely glanced coldly at Kanroji kneeling on the ground, her gaze as if she were looking at a chattering, oblivious pink-feathered sparrow, a contemptuous smirk playing on her lips: "The weak are only fit to have such unrealistic fantasies."

Faced with this sudden marriage proposal and the almost tangible murderous aura of the three girls beside him, Gu Chuan calmly looked at Ganlu Temple kneeling on the ground, a hint of amusement flashing in his eyes.

He reached out and helped Kanroji up, half-jokingly saying, "Let's put the marriage aside for now. But, Miss Kanroji, your temperament is quite suitable for being a shrine maiden serving the gods."

"Eh? A shrine maiden?" Kanroji Mitsuri blinked blankly.

“That’s right.” Gu Chuan’s lips curled into a mysterious smile. He glanced around at everyone present, as well as the three jealous girls beside him, and said in an unquestionable tone, brimming with powerful confidence:

"However, there is one prerequisite for both marriage and becoming a shrine maiden."

"That is—to completely crush that rat named Muzan from this world."

"All beautiful things should be enjoyed slowly after the trash has been swept away."

His words, spoken casually, revealed an absolute confidence that regarded the Ghost King as an ant, instantly transforming the romantic and ambiguous atmosphere of the scene back into a solemn and serious one.

"So, everyone, are you ready?"

Gu Chuan opened his arms as if to embrace the whole world.

"Finally q?=" (II) The hunt of the umbrella-cage-wearing lady begins.

The moment he finished speaking, without giving anyone time to react, he snapped his fingers.

"—[Concept Editing Space Transcription]"

hum-

An indescribable, higher-dimensional power instantly enveloped everyone present!

The Demon Slayer Corps members felt a blur before their eyes, and the solid ground beneath their feet instantly lost its feel. Then, they found themselves in an incomprehensible, bizarre, chaotic void!

There is no sky, no earth, only countless fragments of space, floating around like mirrors, reflecting distorted, unreal scenes. Beneath your feet is a transparent ground, seemingly made of starlight, through which you can look down upon an incredibly vast, otherworldly fortress whose architectural style completely defies the logic of physics.

"This...where is this...?" Uzui Tengen stared at the surreal scene before him, so shocked that he forgot to utter his usual slang.

“Infinite Castle…” Himejima Gyomei cried, his voice trembling, “We…we actually arrived directly above Infinite Castle!”

However, what horrified them even more was that they could not only clearly see the ever-changing rooms in the Infinite City, which were like a maze, but they could also "see" and "hear" the movements of all the ghosts in the city!

At this moment, in the center of the Infinity Castle, Muzan Kibutsuji is hysterically roaring because of Akaza's death. One by one, the Upper Moons of the Twelve Demon Moons are being forcibly teleported here by Nakime's Blood Demon Art.

They could see Doma's frivolous smile, the indifference in Kokushibo's six eyes, Hantengu's cowardice, Gyokko's narcissism... everything was as clear as watching a play right before their eyes.

but……

"Why... do they seem to be completely unable to see us?" Muichiro Tokito asked blankly.

His question echoed the sentiments of everyone.

They hovered above the Infinite City, looking down at the Ghost King and his strongest subordinates, while the Ghost King was completely unaware of this!

[March 7th]: Oh my god! What kind of divine ability is this?! A God's-eye view?! Are we watching a live stream right now?!

[Gem Magician]: This...this isn't just simple invisibility or spatial isolation! He...he directly created an observation phase independent of the prime material world! This...this is the authority of a god!

[Ice Queen]: Hmph, that's more like it. Hiding in the shadows and watching the prey struggle in their final moments before the apocalypse is a pretty good pastime.

"There's no need for panic."

Gu Chuan's calm voice soothed everyone's shock and unease.

"This is a safe observation space that I have created using my powers. It is on the same coordinates as the Infinite City, but in a different dimension. Here, we are absolutely safe observers, while they are the unsuspecting actors on the stage. Their every move will be exposed to our view."
