Chapter 8 On the All-Powerful Properties of Milk...

The Demon Slayer Corps headquarters, the Ubuyashiki residence.

The fragrance of wisteria blossoms swayed in the breeze, but the solemn and tranquil courtyard was suddenly shattered by a scream.

"Hey hey hey—?! Mr. Pei Qi, are you serious? That...that pink-haired monster who made you want to wet your pants just by standing there, you just 'whoosh' chopped him down like he was cutting vegetables?!"

It was Zenitsu Agatsuma who spoke.

He was sprawled on the wooden floor of the corridor, completely disregarding his image, his eyes wide open, his voice shrill with disbelief.

Tanjiro, standing to the side, maintained his polite demeanor, but his clenched fists betrayed his inner turmoil.

Inosuke, meanwhile, was panting heavily, seemingly regretting that he hadn't witnessed that earth-shattering attack.

Pei Qi leaned against a pillar not far away, his lower-realm alloy armor reflecting a cold, otherworldly purple light in the sunlight.

He waved his hand indifferently, even somewhat boredly:

"To be precise, it was a severely injured ghost whose regenerative abilities had been almost completely halted by Mr. Purgatory's 'Crimson Blade'."

"If it weren't for Mr. Purgatory's fatal blow in that game, I wouldn't have been able to finish off the opponent so smoothly. It was just a precise finishing blow in terms of tactics, nothing to brag about."

As the rock pillar, Himejima Gyomei turned the prayer beads in his hand, murky tears streaming down his cheeks: "Namo Amitabha Buddha, to survive such a brutal battle is truly a miracle..."

"A miracle? Maybe." Pei Qi glanced at Kyojuro.

"No need to be modest, Mr. Pei Qi!"

A loud, booming voice interrupted Pei Qi's self-deprecation.

Kyojuro Rengoku sat on the cushions in the guest seat. Although his face was still somewhat pale, his torch-like eyes were shining with an unprecedented brilliance.

"Without your guidance, I would never have been able to comprehend the secrets of the 'Crimson Blade' and the 'Spotted Mark,' and even touch the highest threshold of the legendary 'Transparent World' at the very last moment. More importantly..." Kyojuro looked solemnly at Pei Qi.

"Without that golden fruit you gave me, my body would probably be growing cold by now. The Purgatory Clan will never forget your life-saving grace!"

Everyone present fell silent. They knew very well that Kyojuro had indeed reached the point of exhaustion during that fierce battle.

The act of forcibly overdrawing one's life potential and transcending one's status to activate "stripes" is essentially a form of self-destruction, a one-way ticket.

Logically speaking, even if Rengoku Kyojuro didn't die on the spot, he would inevitably become a cripple due to severe organ failure and irreversible damage to his meridians.

But after consuming Pei Qi's magical "golden apple," a near-miraculous phenomenon occurred.

That warm current not only instantly replenished the deficit in health points, but also performed a precise and meticulous repair.

It forcibly suppressed the hidden injuries left by Kyojuro's years of battles, the wear and tear on his internal organs caused by long-term breathing techniques, and even the slight "life overdraft" caused by activating the mark.

The current Flame Pillar has not only returned from the brink of death, but his physical abilities are even stronger than at his peak.

This regenerative ability, which defies common sense, even left Shinobu Kocho, who was in charge of the diagnosis, with the most bewildered expression of her career during the initial examination.

"I merely offered some pointers," Pei Qi shook his head, his gaze drifting deeper into the mansion.

"More importantly, it's Mr. Purgatory's own comprehension and talent. That ability to comprehend the 'Transparent World' on his own in dire circumstances is truly astonishing..."

Pei Qi paused, his tone becoming serious.

"By the way, regarding your lord, I've heard that he suffers from an incurable disease that is passed down through his bloodline. I've traveled all over the world and witnessed all sorts of strange negative curses or systemic ailments."

I consider myself quite experienced in solving all sorts of "difficult problems." If you don't mind, perhaps I could try to offer my lord a little assistance?

The air seemed to freeze at that moment.

"You bastard! Do you even know what you're saying?"

The tattooed boy, Wind Pillar Sanemi Shinazugawa, who had been sitting in the corner in a wary posture, suddenly stood up, his eyes filled with ferocity.

"Although you saved Rengoku, that doesn't mean you're qualified to touch our Lord! A person of unknown origin, offering to cure the disease that has plagued the Ubuyashiki clan for a thousand years—do you find that amusing?"

"Sanemi, step back."

A soft, gentle voice, yet carrying an undeniable authority, came from behind the screen.

The nine Pillar-level swordsmen instantly stood at attention and bowed their heads in unison. Supported by two young girls, the current lord, Kagaya Ubuyashiki, slowly walked out.

His upper face was covered with decaying lines like purple vines, proof that the curse was eroding his flesh, but his blind eyes revealed a compassion that embraced all things.

"Since this Mr. Pei Qi came with good intentions, not only did he guide the activation of the Crimson Blade and the Mark, but he also single-handedly broke the stalemate that had not been seen for a century and killed the Upper Moon. This is enough to show Mr. Pei's sincerity." Yao Ya smiled slightly, although his subsequent light cough made him look unusually weak.

"My illness has a special origin, stemming from a karmic burden my family has carried for a thousand years. Over the years, I have sought out renowned doctors throughout the land, but to no avail. Since Mr. Pei is willing to try, my crippled body is naturally willing to cooperate."

"Your lord is wise."

Pei Qi stepped forward, his gaze fixed on the purple markings on Yao Zai's face.

He knew very well that the so-called hereditary disease was actually a divine curse brought about by the traitorous fellow clansman, Muzan Kibutsuji, the "progenitor of demons".

This negative state, which arises from an existential association, is essentially no different from a debuff with a "continuous application" logic.

Pei Qi pondered for a moment, and then, to everyone's astonishment, casually made a grabbing motion in the air.

A wooden bucket, shimmering with a silvery-white metallic luster and filled with a milky-white liquid, appeared out of thin air in his hand.

"Is this guy... a mage?" Obanai Iguro muttered under his breath.

Tanjiro and the others were used to it. They even started to silently patch up Pei Qi's secrets in their hearts: this was the "space storage" technique that Mr. Pei had learned while traveling around the world.

"I collected this in a peculiar land in the West," Pei Qi explained, while automatically filtering out descriptions of the "pixel texture" in the background from his mind.

"There lives a sacred cow with a bizarre appearance, an extremely square body, and black and white spots. According to a manuscript left by a legendary local pioneer named 'Steve,' this milk possesses a 'purifying' ability. It doesn't concern itself with medicine; simply drinking it instantly dispels all negative influences..."
