Shattered Innocence: Transmigrated Into a Novel as an Extra

Chapter 553: Father-in-law (3)

”Sorry for the wait.”

The air cracked with tension.

Then—

SWOOSH!

Lucavion vanished.

The space between them collapsed in an instant, his black estoc already driving forward—sharp, relentless, a needle of death aimed directly at Thaddeusʼ throat.

CLANG!

Thaddeus barely caught the thrust, his longsword angling just in time to divert the lethal strike. But Lucavion didnʼt stop. His wrist twisted, redirecting the estoc mid-motion—

SWISH!

A feint. A second thrust, sharper, aimed for the gap beneath Thaddeusʼ ribs.

THUNK!

Thaddeus dodged—just barely. But before he could step away—

Lucavion moved.

He twisted low, his foot sweeping out—

CRACK!

The Dukeʼs knee buckled slightly, his balance thrown off for the first time.

Lucavionʼs smirk widened. Thatʼs more like it.

His estoc flashed upward, carving toward Thaddeusʼ exposed side—

CLANG!

Thaddeus intercepted at the last second, but his guard had slipped—his grip slightly off, his weight uneven.

Lucavion felt it. Exploited it.

SWOOSH!

He lunged, his blade slipping through the smallest opening—aiming straight for Thaddeusʼ heart.

CLANK!

A desperate parry. Sparks flared as the Duke barely redirected the estoc, but—

Lucavion was already moving again.

He pivoted, his body fluid, his estoc a flickering blur of silver and shadow. Thrust after thrust, each strike honed, merciless, targeting nothing but vital points.

Thaddeus grit his teeth.

Faster. Heʼs faster than before.

SWISH! SWISH!

CLANK!

The Dukeʼs sword trembled under the assault. For the first time, he was only defending.

Lucavion stepped in—

A thrust toward the Dukeʼs wrist—

CLINK!

A twist—his estoc flicking toward his throat—

CLANG!

A feint—then the real attack—

SWOOSH!

Aimed for the soft spot beneath his jaw—

THUD!

Thaddeus wrenched himself back, the tip of Lucavionʼs estoc slicing past, grazing his collar.

Too close.

Lucavion grinned. ”Whatʼs wrong, Mister Duke?”

He didnʼt wait for an answer.

Instead, he pressed forward, a relentless flurry of strikes, his estoc a storm of controlled destruction.

Thaddeusʼ sword arm burned under the force. His grip tightened.

Then—

A shift.

His golden eyes sharpened.

Enough.

His stance changed.

Lucavionʼs estoc shot forward—

THUD!

Thaddeus slammed his palm against the flat of the blade, disrupting its path, pushing Lucavion slightly off-balance—

SWOOSH!

He twisted, his longsword carving downward—

CLANG!

Lucavion barely caught the strike, steel shrieking against steel.

A second swing—faster—aimed at Lucavionʼs shoulder—

SWISH!

Lucavion ducked, the wind of the blade slicing just over his head.

Their footwork blurred across the clearing, neither giving an inch. The fight had shifted—

From a battle of skill—

To a battle of instinct.

Lucavionʼs estoc flicked toward Thaddeusʼ ribs.

CLANK!

Thaddeus countered, his blade sliding against Lucavionʼs with controlled force.

Lucavion smirked.

Then—

He let go of his weapon.

Thaddeusʼ golden eyes widened—

But in that instant—

Lucavion twisted his body, stepping inside Thaddeusʼ guard, his palm striking forward—

THUD!

A direct hit.

His fist slammed into the Dukeʼs ribs, the impact forcing the older man back a step.

Lucavion caught his estoc mid-air, spinning it in his grip.

”Getting slow, Thaddeus?”

Thaddeus exhaled sharply.

He hadnʼt expected this.

Lucavion wasnʼt just fighting skillfully—

He was fighting to kill.

The younger swordsman tilted his head, his black eyes gleaming, his smirk widening ever so slightly.

”You wanted me to fight like I did on the battlefield, right?”

He lifted his estoc, the tip glinting under the morning sun.

”I hope youʼre not regretting it.”

Thaddeus exhaled. Then—

For the first time—

He smiled.

The amusement was slight, just a flicker in his sharp, golden eyes.

”Youʼre finally showing your fangs.”

Lucavionʼs grin widened.

Thaddeus lifted his longsword once more, shifting into a new stance.

The morning air trembled.

Lucavionʼs smirk remained, but there was something sharper beneath it now—something untamed, eager.

Thaddeus exhaled, rolling his shoulders. Then, almost casually, he lifted his longsword, his golden eyes steady. ”Enough of this.”

Lucavion tilted his head, curious.

Thaddeusʼ voice carried something different now—not just challenge, but something deeper. A weight of the past.

”…At that time,” the Duke murmured, ”against Gerald—I never got to finish our fight properly.”

Lucavionʼs smirk faltered for half a second.

Gerald.

His master.

The man who had shaped him, forged him, taught him how to wield a blade not just with skill—but with intent.

The thought settled, pressing against something deep inside him.

Then—he let out a quiet laugh, shaking his head.

”Mister Duke,” Lucavion said, tilting his estoc forward. His voice was smooth, unwavering. ”I am not Master.”

Thaddeus chuckled under his breath, shaking his head slightly. ”I know that.”

His grip on his sword tightened. Mana rippled through the air around him, crackling with restrained force.

”But let this old man have his fill.”

Lucavion exhaled, closing his eyes briefly—then they snapped open, pitch-black and gleaming.

”Any fight with a strong is welcomed.”

Without hesitation, he pushed his sword forward.

The air around his blade rippled.

A cold, consuming darkness expanded from the estocʼs tip—

Then—

Black starlight surged forward, streaking through the air like falling meteors.

「Void Starfall Blade: Starlight Needle」

A dozen spears of void energy launched from his blade, cutting through space itself, their edges glistening like fractured stars.

The ground beneath them cracked under the sheer force of it.

Thaddeusʼ golden eyes gleamed.

Mana howled around him—

Lightning surged.

⚡ [Storm Sovereignʼs Dominion: Thundering Aegis] ⚡

A barrier of storm and lightning erupted around the Duke, arcs of electricity intertwining, forming an unbreakable defense. The very air hummed with power, crackling with raw elemental force.

BOOOOM!

Lucavionʼs starlight needles crashed into the barrier, detonating on impact. Black and gold energy collided in a brilliant explosion, sending shockwaves through the clearing. The ground trembled, the sky above momentarily darkened by the sheer clash of power.

Dust and debris swirled.

Then—

A flash.

Lucavion moved.

Straight through the lingering explosion, his estoc already carving through the air—

And Thaddeus was waiting.

Their blades met.

The clash of steel and mana surged through the battlefield.

Lucavionʼs breath came steady, but his body knew the truth—his strength as a 5-star had yet to stabilize. Each exchange with Thaddeus forced him to adjust, to sharpen himself.

And the Duke?

He was relentless.

CLANG!

Lucavion barely dodged a sweeping arc of the longsword, his estoc flashing to parry. But the moment their weapons met, he felt it—

A pulse of mana, controlled, refined, bending the force of the clash in Thaddeusʼ favor.

Damn, heʼs folding the impact into his next strike…

Before Lucavion could react—

SWOOSH!

Lightning surged through the Dukeʼs longsword, twisting through the air in spirals of crackling gold.

THWACK!

The flat of the blade struck Lucavionʼs side, sending him skidding back across the ground, his ribs flaring with sharp pain.

He clicked his tongue, rolling his shoulder as he forced himself upright.

That hurt.

But his eyes gleamed.

”…Not bad, Mister Duke,” Lucavion muttered, rotating his wrist. His grip on his estoc adjusted, the blade humming with dark starlight.

Thaddeus exhaled, shifting his stance. ”Youʼre adjusting well.”

Lucavionʼs smirk widened slightly. ”Oh? A compliment?”

His mana surged.

The estoc glowed—darkness and starlight intertwining.

Then—

「Void Starfall Blade: Eclipse Star Trail」

A streak of void energy burst from Lucavionʼs blade, a cascading trail of blackened starlight searing through the air, splitting the battlefield in two. The very fabric of space bent, the attack curving unpredictably, seeking openings from all angles.

Thaddeusʼ eyes narrowed.

His blade shifted.

Golden lightning swirled.

Then—

⚡ 「Storm Sovereignʼs Dominion: Thunderous Horizon」 ⚡

A field of electric currents expanded around him, warping the flow of space itself.

Lucavionʼs Eclipse Star Trail bent mid-flight, its trajectory disrupted, forced away by the stormʼs dominion.

Lucavionʼs brows twitched. Tch… mana manipulation on that level?

But he was already moving.

His estoc flickered, starlight gathering at its edge—

「Void Starfall Blade: Starsurge」

A piercing thrust—this time, condensed. A single streak of absolute force, refined into one perfect strike.

Thaddeus exhaled.

「Storm Sovereignʼs Dominion: Arcwall Bastion」

⚡ BOOM! ⚡

A shimmering arc of storm energy manifested, intercepting Lucavionʼs Starsurge. The two forces met—

And for a moment, there was no sound.

Then—

CRACK!

The barrier fractured.

Lucavion grinned. Not perfect, huh?

Without hesitation, he pressed forward—

「Void Starfall Blade: Cosmic Steps」

His footwork blurred, warping the distance between them in an instant.

Thaddeusʼ golden eyes flickered.

Lucavion was already behind him.

The estoc struck forward.

For the first time—

The Duke turned his head slightly, eyes sharp.

And smiled.

⚡ 「Storm Sovereignʼs Dominion: Rulerʼs Gale」 ⚡

A burst of wind exploded from his body, knocking Lucavion off his feet.

THUD!

Lucavionʼs body twisted mid-air, but—

SHNK!

A sharp pain flared across his arm.

Blood dripped.

Lucavion landed, his breathing steady but his expression momentarily blank. He looked down. A cut—clean, precise. The Dukeʼs blade had grazed him in that exchange.

”…Heh.”

Lucavion exhaled, his lips curving upward.

This is good.

His body was adjusting, his control sharpening—

And Thaddeus?

He wasnʼt holding back.

Lucavion exhaled sharply, rolling his injured shoulder. Then, raising his estoc once more, his eyes gleamed with untamed excitement.

”This is getting fun.”
