"H-Hey! Xia Feng-senior! What just happened?!"
Zenitsu panicked.
The entire forest had suddenly gone silent.
He still had no idea what had happened.
Why had Xia Feng suddenly fallen through a door in the ground?
Zenitsu gulped nervously.
"No… I have to report this to headquarters immediately!"
Without wasting another second, he sprinted out of the forest.
Meanwhile…
Inside the Infinity Castle.
Japanese-style buildings stretched endlessly in every direction.
Up, down, left, right—
The entire space was completely chaotic.
Xia Feng looked upward and noticed that even above his head there were rooms.
Inside one of those rooms, someone sat calmly.
Xia Feng smiled faintly.
"So it's you… Kokushibo."
"Last time you managed to escape."
"Didn't expect you'd come looking for me again."
Kokushibo simply stared down at him silently.
Xia Feng lifted his Nichirin Blade.
"Not talking?"
"Fine. I'll come to you."
He kicked off the ground like an arrow and shot upward toward Kokushibo.
Dong!
At that exact moment—
A biwa string echoed.
Xia Feng suddenly passed through a door and landed right back where he started.
Xia Feng chuckled.
His gaze shifted toward the one controlling the castle.
Nakime.
The one-eyed demon holding the biwa.
She was extremely troublesome.
"Looks like I'll have to kill Nakime before I deal with Kokushibo."
Xia Feng narrowed his eyes.
His blade turned.
This time he rushed directly toward Nakime.
But Nakime plucked her biwa again.
The space shifted.
Xia Feng's direction instantly changed—
And he was sent flying toward Kokushibo instead.
Kokushibo gripped his sword with both hands.
Moon Breathing — Second Form: Pearl Flower Moonlight!
Moon-shaped slashes descended.
Fast.
Wide.
Far beyond what ordinary breathing techniques could achieve.
Moon Breathing, the original derivative of the Sun Breathing lineage, truly possessed terrifying power.
Even today, few breathing styles could rival it.
Xia Feng raised his Nichirin Blade.
But if it came down to speed—
Thunder Breathing would not lose.
Thunder Breathing — First Form: Thunderclap and Flash!
Bullet Time!
Xia Feng's perception increased dramatically.
Kokushibo's movements slowed within his vision.
Against such slowed attacks—
Dodging was simple.
He ducked beneath the slash.
Of course, Bullet Time alone wasn't enough.
His perception had accelerated, but his physical speed remained the same.
That's why Thunderclap and Flash was necessary.
He dodged low—
Then thrust his blade forward.
Slash!
Just then—
A voice rang out.
"I knew the Demon Slayer Corps' Special Advisor was powerful!"
"Not killing you last time was my regret!"
"But this time it's different!"
"I'm excited… so excited!!"
The door beside Kokushibo burst open.
Akaza rushed out and threw a powerful punch at Xia Feng.
Xia Feng frowned.
Intangibility.
Akaza's fist passed straight through his body.
Akaza's eyes gleamed with excitement.
"Yes! That technique!"
"That mysterious power like a Blood Demon Art!"
"I can't deal with it at all!"
Kokushibo calmly swung his blade through Xia Feng's body.
But it passed through harmlessly.
Kokushibo spoke quietly.
"A technique like this must have a flaw."
"If we cannot discover it quickly… we extend the battle."
Even though their attacks currently couldn't harm Xia Feng—
He remained completely calm.
Akaza grinned.
"What if I keep my fist inside your body?"
"Wouldn't that force you to stay intangible forever?"
Kokushibo moved behind Xia Feng and slashed again.
"While intangible, he cannot attack us either."
Xia Feng had to admit—
Kokushibo's observation ability was incredible.
This was indeed the biggest weakness of his intangibility.
Kokushibo continued.
"We only need to strike the moment he becomes tangible."
He raised his sword—
But did not attack.
Instead he waited.
Xia Feng waved his hand lazily.
"Actually, I'm waiting for Muzan."
"This should be his base, right?"
"Infinity Castle."
"So where is Muzan hiding?"
"Don't tell me he's scared I'll kill him."
Kokushibo and Akaza stood on both sides of Xia Feng, waiting for the moment he materialized.
Akaza frowned.
"So you're planning to stay like that forever?"
Kokushibo remained silent.
But he kept his blade ready.
Xia Feng shrugged and sat down casually, resting his chin on his hand.
"Isn't that easy?"
"As long as I stay intangible, you can't touch me."
Akaza shouted in frustration.
"That's boring!"
"I was planning to kill you today!"
"Don't ruin the fun!"
"Being killed by me should be an honor!"
"The weak should die, shouldn't they?!"
Xia Feng ignored him and continued observing the surroundings.
All the Upper Ranks should be here now.
Which meant—
Muzan was probably watching somewhere.
After all, Muzan would want to personally witness the death of a threat like Xia Feng.
And Xia Feng had intentionally created the impression that he couldn't defeat multiple Upper Ranks at once.
Surely Muzan would appear.
Kokushibo suddenly spoke.
"Actually, this situation benefits us."
"The battlefield… is not here."
Xia Feng paused.
That sentence contained too much information.
For a moment, he couldn't figure out what Kokushibo meant.
Then—
A voice appeared behind Nakime.
"It seems you've run out of options, Xia Feng."
A figure stepped into view.
A woman in a kimono.
Her slightly curled hair was neatly pinned up.
Her features were delicate.
Her red, catlike eyes made her appearance strangely alluring.
But when she spoke—
The voice was unmistakably male.
Xia Feng narrowed his eyes.
Muzan Kibutsuji.
The coward had finally appeared.
But…
Why was he dressed like that?
Xia Feng grinned.
"So you're one of those legendary cross-dressing bosses too."
Excitement flashed in his eyes.
