Yandere Monster Evolution: My Blind Wife Will Become a Demonic Queen

Chapter 121: High Noble; Crimson Lineage (2)

Cadvic stumbled backward in shock. Arcs of red lightning were also dancing across his whole form, hissing as they cauterized the flesh and turned his regal garments into blackened ash.

"You..." Cadvic choked out. "Carmilla... it can’t be. The Blood Fire leaves nothing behind. I watched the Grand Elder pour the embers himself!"

Carmilla didn’t answer right away. She stood perfectly still in the crater. Beneath my paper bag mask, my jaw was practically hitting the floor because of the absurdity of the situation.

Soon, Cadvic straightened his spine, and his pale face contorted into a mask of pure, venomous rage. Even with one arm gone, the mana density radiating from his body was suffocating.

"Do you think a single surprise strike changes the hierarchy of this kingdom, child?" Cadvic hissed, his voice echoing off the sharp gothic spires. "Your father was weak. Lord Val was a fool who believed our race could coexist with the lower beings. He wanted to ration the blood. He wanted to negotiate with the Elven courts and the Dwarven lords as if we were equals!"

Carmilla slowly raised her dark blade, the tip pointing straight at Cadvic’s throat. The red lightning buzzing along the edge grew louder, casting an eerie, crimson glow over the surroundings.

"My father trusted you," Carmilla said. "He called you a friend and a... brother."

"And that was his final mistake!" Cadvic barked, letting out a sharp, mocking laugh that sounded like dry bones grinding together. "He was a sentimental old fool. We was meant to rule, not to barter. It was remarkably easy, really. A few whispered words to the Grand Elder, a fabricated report about Val conspiring with the Dragon Kingdom to seal our gates... and the decree was signed. Your family was erased from the archives before the sun even set."

Behind us, Seok adjusted his grip on his blue spear, his cartoonish mask tilting slightly as his mind processed the information.

"Internal political sabotage," Seok murmured. "Brian, this entity isn’t just a combat unit. He’s the catalyst for the historical fall of this entire Gate."

"I know," I replied smoothly, though my brain was working overtime to connect the dots.

The pieces were finally starting to click into place. The novel had mentioned that the Vampire Kingdom fell because of a sudden, catastrophic resource depletion following a total war, but the text had skipped the dirty details of the palace coup that started it. Cadvic hadn’t just destroyed Carmilla’s family—he had systematically altered the trajectory of an entire world.

"You manipulated the Grand Elder," Carmilla whispered, her blade dropping half an inch. "You forced the kingdom into the Great War."

"Forced? No. I liberated us!" Cadvic roared, his left hand gesturing wildly toward the shattered ruins around us. "We were the peak of creation! Why should we hide in the shadows while the Elves tended their forests and the Dwarves hoarded their gold? I gave the kingdom a purpose. We marched across the old continents. We broke the Elven courts. We tore the wings off the Fairies, shattered the mountain fortresses of the Dwarves, and dragged the Dragon Lords down from the sky by their tethers!"

He stepped forward, his polished boot splashing into a puddle of crimson condensation, and his ruby eyes flared with a sick, nostalgic pride.

"We turned their kingdoms into our pastures," Cadvic sneered. "We drove the Demons into the abyss and made the Humans our literal livestock. For a hundred years, we drank from golden chalices filled with the purest essences of a dozen countries!"

I listened to his grand speech, and a smirk formed on my lips.

It was a classic tragedy of progression fantasy. A faction gets too strong, eliminates all competition, and realizes too late that the system they built requires an endless supply of fuel to maintain its baseline.

"And look where that grand conquest got you," I spoke up, my voice cutting through Cadvic’s dramatic monologue like a blunt razor.

Cadvic’s gaze snapped toward me, his fangs bared in a silent snarl. "Silence, masked insect! You know nothing of our glory!"

"I know how to read a ledger, Cadvic," I countered, taking a slow step forward until I was standing right beside Carmilla. "You wiped out the Elves. You slaughtered the Dwarves. You bled the Humans until there wasn’t a single breeding stock left on the entire continent. You conquered everything, and then you realized something incredibly funny, didn’t you?"

I leaned forward slightly.

"Vampires don’t produce blood," I said. "You are parasites. And a parasite that eats its host completely doesn’t win. It just starves to death in an empty house."

Behind me, Hana let out a soft gasp, her fingers tightening around her glowing staff as my words hit home. Even Grog lowered his broadsword slightly, his heavy features settling into a look of profound realization.

"The war didn’t just destroy your enemies," I continued. "It broke the Vampire Kingdom itself. The civil war that followed wasn’t about glory or lineage; it was a desperate, feral scrap over the remaining scraps in the pantry. Your soldiers turned on each other. Your noble families tore themselves apart just to drain the last remaining drops from their servants’ veins. You didn’t outlive your prey because you were superior. You outlived them because you were the last ones left in the graveyard."

Cadvic’s pale face went through a remarkable transition—from rage, to shock, and finally to deep, trembling humiliation. Every single word I said was a direct hit to his fragile ego.

"You..." Cadvic whispered, his voice shaking violently. "How can a human know about the Stagnation Period? That information was sealed in the High Vaults!"

"Like I said, I have an excellent research department. Moreover, I possess something no one else possesses," I replied, casting a quick glance toward Vera, who was still standing behind me.

"It doesn’t matter what you know," Cadvic hissed, his left hand suddenly dropping to his side. "You will all die here. The Blood River and Blood Fire will consume your pulses!"

Before he could channel his remaining mana into the surroundings and attack us, Carmilla moved.

There was no sound. No announcement of a skill.

BZZZZZT!

A single, violent arc of blood-red lightning tore through the place. The spatial pressure around her completely collapsed, creating a localized vacuum that drew the sweet-smelling mist straight into her path.

Cadvic didn’t even have time to scream.

Carmilla appeared directly behind him, her dark blade already sheathed back in its leather scabbard with a sharp, metallic click.

For a fraction of a second, the high noble vampire stood perfectly still in the center, his silver hair fluttering lazily in the wind. Then, a thin, crimson line appeared across his pale throat.

SPLAT!

Thick, blackish-red noble blood erupted from the wound, and Cadvic’s head slid clean off his shoulders, hitting the cracked cobblestones with a dull, heavy thud before his body collapsed into a heap of tattered silk and ash.

[SYSTEM NOTIFICATION]

[An elite entity has been eliminated.]

[The local ’Mana’ density has decreased by 8%.]

The bright blue text flashed across my vision, confirming the kill. The surrounding vampire soldiers, who had been circling our perimeter like hungry wolves, let out a collective, terrified screech before instantly scattering into the dark alleys and high spires, vanishing from sight.

The avenue was suddenly completely silent.

Carmilla stood over the remains of her uncle, her head tilted down toward the ash. She didn’t look victorious. She didn’t look relieved. She just looked incredibly tired.

"Holy... hell," Grog muttered, his hands trembling so violently that the tip of his massive broadsword scraped against the stone with a loud clink. His wide eyes shifting from the headless Duke to the quiet girl who was just standing there casually. "She... she just one-shotted a boss without even breaking a sweat."

Jisu didn’t say a word. She was staring at her ring-covered fingers, her teeth chattering slightly from the residual chill of the red lightning. She had spent a decade in the hunter industry, surviving high-risk raids through careful coordination and defensive tactics. Seeing an ancient noble entity get dismantled in less than three seconds by a teenager hugging a sword was completely shattering her understanding of power scaling.

Beside them, Hana looked like she was about to drop her staff. "That... that wasn’t a standard skill. The mana intensity... it felt like..."

"A high-frequency bloodline inheritance," Seok finished her sentence.

He stepped forward, his cartoonish mask tilting slightly as he analyzed the crater. His posture remained disciplined, his blue spear held loosely but ready.

He glanced toward me, his eyes narrowing behind the cutouts. ’Brian didn’t just hire muscle,’ Seok thought to himself, his mind frantically adjusting his assessment of my network. ’He explicitly found a direct biological counter to the regional boss. He knew the history, he knew the lineage, and he knew the exact psychological triggers to make the entity expose its flank. The calculation is flawless.’

At the very rear, Black remained entirely unmoved. He had watched the entire execution without shifting his hands from his pockets.

"An interesting family reunion," Black murmured, his deep voice carrying a sharp, dangerous undertone that cut through the hunters’ murmurs. "You have some very peculiar friends, Brian. I’m starting to think that you have more than you show."

I can’t blame him or anyone else present.

Cadvic was ’A-’ Rank, but this girl just killed him before he could even do anything.

Monsters ranks are completely different from the Gate or Hunter system. While, there are only five sections for hunters, the monsters have more than ten. They go from D- to S+ Rank, with each having a ’-’ and ’+’.

I don’t know if she knew his blind spot or if he underestimated us and had his guard down. Still, wasn’t that just too easy?

Urrrg. My mind is gonna explode from all this. I must ask Viora how she knows her and how she got into our world when she was supposed to be here.

"It is done," Carmilla whispered softly while I was thinking.

"Nicely handled," I said, stepping toward her while keeping my movements casual. "Though, I suppose family reunions in Gate worlds are always a bit messy."

Carmilla turned her face toward me, her dark hair parting to reveal her dull crimson eyes. She didn’t ask how I knew about the history of the Stagnation. She simply gave a short, polite nod before walking back toward the rear of our circle, taking her place behind Hana without saying another word.

I watched her go, then I slowly turned around to face Vera.

She was standing right where I had left her. The casual, playful atmosphere we had shared on the wooden pier two days ago felt incredibly distant right now.

"Vera," I called her. "A sword user who happens to be the last surviving heir of the, I think, Crimson Lineage... maybe? Looking at her lightning... that’s not a ’regular contact’ from your old days."

"I never said she was regular, Woo Jin," Viora murmured sweetly, her breath feeling warm through the paper layers as she leaned closer to my shoulder. "And you also didn’t tell me that it was a Vampire Gate."

She reached out, her fingers lightly brushing against my wrist, her grip tightening just enough to let me feel the rapid, steady thudding of her pulse.

"Are you angry with me?" she whispered with a tone that carried a dangerous, possessive edge, which made the hairs on my arms stand up. "Do you think I’m keeping secrets from you? Because if you want to know everything, Woo Jin... I can tell you. I can tell you every single thing I’ve done since the day I was born. But you have to promise me one thing first."

I narrowed my blue eyes. "What’s that?"

"Don’t ever look at me the way you looked at the others," she murmured. "Like I’m just a historical variable on your board. If you ever look at me like that... I might actually lose my mind, and you might also end up losing your head."

Hearing her words, the tension in my chest suddenly dissolved, replaced by a small, helpless chuckle.

"You really are terrifying, Vera," I whispered back, my fingers turning over to lock tightly with hers. "Don’t worry. You aren’t a variable. I already told you what you are to me."

"Absolute resolve," she repeated softly, her posture relaxing instantly as she leaned her weight against my shoulder once again. "Good. Don’t forget it."

I looked up toward the tall, dark castle sitting on the hill in the distance. The bloated red moon was still hanging overhead, but the crimson river seemed to be moving slightly faster now, as if the death of the Duke had unlocked a vital node in the dungeon’s structure.

"The doorman is gone," I called out to the remaining Hunters, my voice recovering its smug, confident ring. "Now, let’s go see what the King of this graveyard has waiting for us in his castle."

Black let out a low grunt from the rear, his hands still buried in his pockets as he stepped over Cadvic’s ashes. "Lead the way, Brian. Let’s see how much further that research department of yours can take us before the floor falls out."

"Don’t worry, Adrian," I muttered, adjusting the edges of my paper bag mask as we started walking toward the spires. "The fun is just getting started."
