Chapter 80: Trapping a King: The Lone Particle Catalyst

Slam!

The massive iron door crashed shut. The deafening, metallic echo vibrated violently through the damp stone foundations of the castle cell.

Clack. Clack. Thud.

Heavy brass keys ground harshly against rusted tumblers. A thick locking bar dropped into its external slot with a decisive, heavy strike.

Clink... clink... clink...

The rhythmic, heavy footsteps of the armored elite guards slowly drifted away down the long corridor, eventually melting into an absolute, suffocating silence.

Cassius was left alone in the pitch black.

He sat perfectly still on the freezing stone floor. Heavy chains bound his wrists tightly. Faint, glowing purple warding runes were deeply etched into the metal links... specifically forged to suppress volatile vampire magic.

But Cassius didn’t pull against them. He didn’t panic.

In the crushing dark, his heartbeat remained slow, mechanical, and perfectly controlled. To the guards, he was just a broken slave thrown into the deep dark to rot until the King woke up.

But internally, Cassius’s mind was moving at hyper-speed.

"Stupid, drunken aspergillus" Cassius mused coldly, a sharp grin cutting through the darkness.

"And that Governer idiot... genuinely thought he was breaking my pride by making me clean up his master’s mess."

His intellect instantly replayed the precise physical choreography of the steam-choked bathhouse. He remembered the exact moment he bypassed the clean sponges on the cart. He remembered deliberately grabbing the dirtied, wet cloth instead.

It hadn’t been an act of submissive obedience. It was a flawless tactical execution.

Deep within the damp fibers of that foul rag lay a microscopic, harvested speck of his own shape-shifting magic. When he had knelt directly in front of the heavily intoxicated monarch, systematically wiping down the dark puddles, he had used the ambient moisture of the volatile blood-wine to his absolute advantage.

"You left yourself completely exposed, Vilucious," he thought.

With a simple, calculated swipe of the dirty cloth across the rim, the invisible particle had transferred flawlessly into the overflowing puddles of wine.

As the unhinged, heavily stumbling King staggered forward, mumbling incoherently, his footing failed entirely. The chaotic stumble forced the monarch to swallow a mouthful of the splashing, miniature volatile mixture.

Right there, right in front of Cassius’s eyes, the King completely consumed the viscous magic... unknowingly eating the microscopic seed. It slipped down his throat and deep into his digestive system, entirely undetected. Unstoppable.

In the silent void of the cell, Cassius let out a quiet, dark exhale.

Haaaaah.

His thoughts drifted back to the genesis of this forbidden anomaly within his vampire system. The very first time it appeared was during his brutal clash against the Assistant General. When the high-tier magic had flared, his analytical vision had caught sight of a single, shimmering residual particle drifting in the air.

Just magical exhaust, Cassius had thought at the time, completely ignoring it. A useless byproduct of a system I barely understand.

But he was wrong. The true revelation struck during the bloody chaos of the Gala, right in the middle of his desperate fight against Lord Vilucious. As the raw magic receded that day, the exact same phenomenon occurred. One single, stubborn particle materialized, refusing to dissolve into the atmosphere.

Sitting on the floor amidst the wreckage, bleeding and exhausted, Cassius’s genius intellect had locked onto it.

Wait...

Cassius had mused internally, his eyes narrowing as the guards marched toward him.

Everything else burns out, but this single spark remains perfectly stable. It isn’t exhaust. It’s a concentrated core. If I leave it, they’ll study it. I need to pocket this.

Acting on pure, calculated instinct, he had shifted his weight, sitting directly over the microscopic particle. He drew it into his skin wisely, absorbing it without a single guard or noble in the grand hall noticing a thing before he was forcefully dragged away.

For days afterward, he was consumed by intense confusion. He didn’t know how to activate it, let alone why his system generated it.

Before his next calculated move, a high-stakes pickpocketing attempt; he had stared at the hidden energy signature resting within his own palm, his mind racing with theories.

’Why does it just sit there? Magic in this system requires my soul to rip itself apart,’ Cassius had reasoned, a dark frustration tightening his jaw.

’Every time I shape-shift, I have to plunge myself into absolute emotional distress. It drains my sanity. It drains my life force.’

Confusion and tactics were eating him that moment, then he thought:

’But what if this lone spark is a shortcut? What if I don’t need to rebuild the engine every time... what if I just need to swallow the spark?’

Driven by a dangerous scientific curiosity, he didn’t just hold it... he chose to consume it. He internalised it, letting the lone particle slide down his throat.

The result was an absolute masterpiece of biological engineering. Normally, his high-tier shape-shifting magic required a massive, soul-crushing wave of raw fury to ignite.

But the moment he ate the particle during the pickpocketing attempt, it acted as a flawless, highly efficient catalyst.

Without needing a massive emotional breakdown, the seed effortlessly unlocked his magic with perfect, deadly precision.

And right as the pickpocketing magic faded, the system’s rigid rule proved itself true once more:

Snap. One fresh, miniature particle arose from the ashes of the spell. Cassius caught it instantly, stowing it away for a final confirmation.

That confirmation came in the dark, secret base when he bit Lordess Florianthum. As the predatory magic receded from his veins post-bite, a single, glowing particle materialized exactly as predicted.

He harvested it: and that precise, lone particle from the secret base was the very weapon he had just fed to Lord Vilucious.

But sitting in the high-security cell now, Cassius knew the seed inside the King was a dead spark, far too distant to ignite on its own. He closed his eyes.

He forced his rigid, analytical walls to crack wide open, plunging his mind into the burning ash of the apocalypse, the theft of his freedom, and the absolute humiliation of his human existence.

Crack.

A tidal wave of genuine, unadulterated human fury erupted from his chest.

Thump-thump! Thump-thump!

Inside the pitch-black cell, Cassius’s eyes flashed a brilliant, terrifying predatory hue. The raw emotional breakdown supercharged his veins, broadcasting a dark, pulsing wave of energy through the cold stone floors straight into the palace above. A dangerous, mocking smirk spread across his lips in the dark.

"What did you truly think of me, Vilucious?"

Cassius whispered into the empty night, his voice dripping with absolute, lethal irony.

"You sit on your throne believing you are the ultimate kingdom maker...huh"

The rest was the words that he thought, cold and precise:

Yet, you don’t even realize that your own rigid military protocol is what gave me the perfect blueprint to poison your veins.

Enjoy the harvest, you miserable king.
