Wait, How Did My Digital Girlfriend Become a Sword Immortal?

"Huai'an, my brother, let me introduce you—this is your attending physician for the cancer treatment, aRecovery-Type Awakened, Xiang Xiaoyuan."

Inside a seemingly ordinary spice shop in the Panjiayuan Market lay a hidden chamber.

Sitting across from Chen Huai'an wasThe Bearded Guy, who now sported a flashymechanical arm—a recent upgrade from his mechanical ascension. Beside him stood a shy, soft-smiling girl.

Chen Huai'an glanced behind the folding screen and noticed another woman sitting quietly. She made no move to show herself, and he wasn't interested enough to pry. Instead, he greeted Xiang Xiaoyuan with a polite smile.

The girl wasn't a stunner, but her presence felt gentle and serene—like a scene of water flowing under a small stone bridge. She had pale, delicate skin and large, expressive eyes. The moment Chen Huai'an's smile landed on her, her cheeks flushed a deep pink, and she lowered her gaze to her toes.

The Bearded Guy beamed. "Huai'an, don't let her shy demeanor fool you! Xiaoyuan's aMaster-Rank Grade A Awakened! Took me a hell of an effort to get her here! She's savedhundredsof people with her ability!"

Hearing him pile on the praise, Xiang Xiaoyuan blushed even deeper—so much so that she looked like she wanted to bury her face in her ample chest.

"That impressive?" Chen Huai'an raised an eyebrow, genuinely intrigued.

"Impressive? More likemiraculous! Let Xiaoyuan take a look—come on, don't be shy, hahaha!"

The Bearded Guy's motives weren't entirely selfless. He had recently learned fromOld Lithat Chen Huai'an wasthat kid with the insane sword aura.

If he could get Chen Huai'an cured, maybe—justmaybe—the guy would take an interest in joining theDemon Slayer Bureau.

His eagerness doubled at the thought.

Chen Huai'an and Xiang Xiaoyuan sat facing each other.

"So, what should I do?" he asked.

Xiang Xiaoyuan's voice was soft, barely a whisper:

"J-Just… give me your hand…"

Her lashes quivered as she kept her gaze lowered, voice as delicate as her petite frame.

Chen Huai'an reached out—overshooting completely and extending his armover her head.

Xiang Xiaoyuan: "…?!"

"Umm… could you… bring it back a bit? I can't reach like this…"

He awkwardly reeled his arm back, now curled comically in front of his chest.

Xiang Xiaoyuan: "…"

Was thisreallythe legendary powerhouse The Bearded Guy raved about?

Why did he feel like a socially-awkward NPC?

With a small sigh, she composed herself.

"J-Just place your hand…in mine…" she repeated, cheeks puffing slightly in exasperation.

"Oh."

Chen Huai'an obediently laid his hand in hers.

Her palm was small, soft, and warm.

A milky-white glow flared from their contact, enveloping his wrist.

Xiang Xiaoyuan's usual bashfulness vanished. Her brows knit in deep concentration, her face solemn and tense.

A moment passed.

She released his hand, palm slightly damp with sweat.

Her wide eyes stared at him, brimming with disbelief—

Like she had just encountered somethingimpossible.

"You… this…How?"

The Bearded Guy immediately leaned in. "Xiaoyuan! What's going on? Talk to me!"

"Seventy percent."

Her voice was tight with shock.

"Seventy percent of his body is already overrun with cancer cells. They're devouring his body's nutrients every second—by all logic, he shouldn't be alive. Not forone minute."

She paused.

Because—by all logic—

Chen Huai'an should have alreadydropped deadduring her diagnosis.

But here he sat.

Not only alive—

Butflushed,bright-eyed, andfull of vitality.

It was impossible.

The law of conservation of energy applied even to cancer cells.

They couldn't proliferate endlessly without consuming his life force.

Yet—something elsewas feeding them.

Some otherenergy sourcehad been sustaining these cancer cells—keeping them too busygorgingto become malignant.

But The Bearded Guy only cared aboutone thing:

"Xiaoyuan, cut to the chase! Can you fix him or not?!"

Xiang Xiaoyuan's gaze flicked to Chen Huai'an.

Then, she gave a soft, firm nod.

"Before learningBreath Cultivation Techniques, my ability had time limits… But now—"

"With breath cultivation supporting me, I can maintain myUniversal Healing Factorlong enough to wipe out every last cancer cell inside him."

Her ability—Universal Healing Factor—was legendary.

It could heal wounds, obliterate disease, and even regenerate lost limbs.

The Bearded Guy, despite having known her power, had opted formechanical ascensionover limb regeneration—simply because hewantedhis flashy mechanical arm.

But cancer?She could cure that.

"Seriously?!" The Bearded Guy slammed his knee in excitement.

Xiang Xiaoyuan blushed again. "I… I'm the only one in the world who can."

"Good—GOOD!" The Bearded Guy all but jumped for joy.

A talent like Chen Huai'an—surviving this broken world—was a victory in itself, bureau recruit or not.

Chen Huai'an's heart pounded with exhilaration.

Before today, he had misunderstood everything.

He had thought his bizarre symptoms camefromthe cancer—

Hell, he even jokingly called himselfTumor Man.

Back then, he'd haveregrettedlosing his cancer—

What if his powersvanishedwith it?

But now—

He knew.

His abilities hadnothingto do with the cancer.

The cancer was just…there.

So—Why hesitate?

"Xiaoyuan," he said with a grin, "Let's get rid of this crap."

"Xiaoyuan, need anything?" The Bearded Guy was practically bouncing.

"No. Just give us… a quiet room."

The Demon Slayer Bureau'sTianfu District Outpostwas a labyrinth far beyond Chen Huai'an's expectations.

He had thought thehidden roombehind the spice shop was already the final secret—

But it led toanothersecret door.

Behindthat—anelevator.

The elevator opened into a sprawling subterranean complex—

A task hall, mission boards, and dozens of private rooms.

Since the outpost was newly constructed, most rooms were still awaiting assignments.

Xiang Xiaoyuan chose one.

Inside—

"Chen… Chen Huai'an, just lie on the bed."

Her voice trembled slightly.

The warmth on her cheeks hadn't faded since they entered the room—

Alone. Together.

But the moment her hands touched his leg—

Every trace of nervousness vanished.

Her face—resolute.

"We're starting—now!"

Soft white light burst from her eyes—

Delicate veins of glowing patterns spread down her arms and calves, tracing likeleafy vinesover her skin.

Thoseveins—were herconduits.

The pipelines for herUniversal Healing Factor.

The invisiblesoldiersshe deployed—

They flooded Chen Huai'an's body—

And thebattlebegan.

Within his body—

Thecancer cellscrumbled.

Cut down by an onslaught that was swift, relentless—absolute.

To her healing factor—

The cancer was nothing more thaninsects under a boot.

The tide was one-sided.

Victory seemed imminent—

Until.

When her power reached hischest—

The battlefieldshifted.

The cancer cells…

Suddenly.

Fought back.

Amutinyerupted within his body.

Cancer cells near hisinternal organs—

Expanded.Swelled.Multiplied.

Faster than humanly possible.

Not only that—

They began tostrategize.

They hid behind normal cancer cells—

Using them asmeat shields.

And when her healing factor arrived—

Thegiant mutant cellssprang from cover—

Anddevoured her soldiers whole.

Xiang Xiaoyuan's pupils shrank.

Her brow drenched in sweat.

This… This wasn't cancer.

This was somethingelse.

Her entire focus was within his body—

So shedidn't see it.

Above his heart—

Chen Huai'an's chest—

Suddenly.

Bulged.

His flesh—

Twisted.

Contorted.

Swelled.

With a sickeningrip, his T-shirt shredded.

From his chest—

Somethingemerged.

A grotesquelimbof writhing flesh—

Warped into the shape of ahuman arm.

At the limb's center—

A malformedpalm.

And within that palm—

A single, bloodshoteye.

It snapped open—

And—

Stared.

Stared directly—

At.

Her.
