My Horny Stepmom Turns Me into Her Vampire Slave

Chapter 193: Isabelle’s true power (1)

A fierce slash from Isabelle comes from one side.

A devastating hammer strike from Constantine crashes in from the other.

Yet Zayn stops both attacks at the same time with embarrassing ease. He blocks Isabelle’s blade with his own black-blood saber, then catches Constantine’s hammer with his bare hand.

Finally, a thunderous burst of energy erupts from his body, forcing them both back.

Isabelle and Constantine barely avoid the overwhelming shockwave by leaping backward at the last second — she lands to Zayn’s right, while he lands to his left.

They raise their weapons again, standing ready to launch another attack.

"Constantine Serev. Platinum Death. So, what do you think of my new power? Cat got your tongues? I can see the fear and worry in your eyes. Not so cocky anymore now that even the two of you together can’t keep up with me?"

"Your new power? Don’t make me laugh," Constantine hisses. "I don’t know where that dark power came from, but it sure as hell isn’t yours. What evil entity did you make a deal with? And what did it cost you?"

"None of your fucking business, you stupid old man!"

Then Zayn turns to Isabelle with a smug grin.

"And what about you? Nothing to say? Did my overwhelming power leave you speechless? Funny... you were the one who kept saying there was no way to surpass your limits. Looks like you couldn’t have been more wrong. If I’d listened to you, I’d still be the weak, limited vampire I used to be. But now... now I’m about to kill the woman who’s known as the strongest vampire in the multiverse! Get ready to say goodbye to that title forever — because before long, it’ll be mine!"

Isabelle slowly shakes her head, a faint, pitying smile on her face.

"You really think that mediocre power is enough to surpass me? You’re sadly mistaken. The strongest vampire in the multiverse? Please. If that’s the best you can do, you wouldn’t even make the top five."

"Q-Quit talking bullshit!" Zayn roars through gritted teeth, his face twisted with frustration. "You’re acting like you’re still the strongest, but it’s obvious you’re bluffing! You’re already fighting at full power, and even then you’re barely keeping up with me despite the two of you teaming up against me!"

"Oh... you really think this is my full power? How naïve. I’m not even close."

"I watched you fight countless powerful enemies back when I was just a regular soldier in the Scarlet Army! I know exactly how far you can push yourself, and I’m absolutely certain this is your limit!"

"If you’d been there the night those damned Dulcars overthrew the throne, you wouldn’t be saying that."

A look of sheer terror suddenly spreads across Constantine’s face, as if Isabelle’s words had awakened memories he’d desperately wanted to forget.

I-Isabelle... is she really about to unleash that power again...?

The memories come flooding back.

The day he was forced to join forces with two Scarlet Army Generals just to try to contain Isabelle’s unstoppable rampage at the height of her power.

Levreeshka Dulcar had spent months meticulously planning the assault on the throne.

To make it possible, she’d lured Isabelle away from the royal castle under false pretenses.

But devastation on that scale could never go unnoticed.

That’s why Constantine and the two generals had been tasked with keeping Isabelle away from the battlefield for as long as possible once she realized she’d been deceived and tried to make her way back to the castle.

Although they managed to slow her down, the brutal battle left all three of them utterly broken.

Constantine knows all too well that if Isabelle had been fighting to kill them instead of simply carving a path toward the castle as quickly as possible, they almost certainly would’ve died.

But back then, she couldn’t afford to waste even a single second on them.

Now it’s different. She’s no longer racing against time.

Her enemies are standing right in front of her. And for the first time in a very long while, Constantine genuinely fears for his life.

All of a sudden, the ground begins to tremble.

Long, deep cracks split open beneath their feet, and the air around them suddenly grows heavy.

The pressure is so overwhelming that even Zayn and Constantine have to struggle just to keep themselves from dropping to their knees.

"T-This can’t be... What the fuck is happening...?!" Zayn stammers.

"She’s drawing on the Sanguis of both her hearts at the same time..." Constantine replies, more tense than ever.

"Her two hearts...? What the fuck kind of nonsense is that?!"

"I’m not surprised you’ve never heard of it — only those closest to her know the truth. The secret behind Isabelle’s seemingly endless stamina is that she was born with two hearts. Normally, she draws power from one while the other recovers, then switches between them, allowing her to fight at full strength indefinitely. But when she chooses to draw on the power of both hearts at the same time, her already overwhelming strength doubles. At that point... I don’t believe there’s a single being in the entire multiverse capable of stopping her," Constantine concludes, his face twisted with fear and anxiety.

"She can become a hundred times stronger for all I care — it doesn’t matter! My new power has no limits! There’s no way that—"

Zayn suddenly cuts himself off the moment his gaze shifts away from Constantine and back to Isabelle.

"W-What the fuck is this supposed to mean...?!"

Her appearance hasn’t changed at all. Not even the size of her aura has increased.

Yet it’s unimaginably denser. Far more oppressive than before.

But what unsettles Zayn the most is that Isabelle herself now seems distorted.

The crimson vortex swirling around her has grown so dense and concentrated that it’s warping space itself.

When Isabelle takes a single step toward Zayn, her foot crushes the ground beneath it, as though she weighs a thousand times more — yet her movements remain as effortless as ever.

"You’re a fool, Zayn Thzraneel," Constantine says, his voice trembling. "Did you really think that little trick would be enough to make you the strongest vampire? Keep your eyes wide open for whatever little time you have left to live — you’re about to witness the true might of the strongest vampire in the multiverse."
