Chapter 615: 615. Another Transformation And Power Boost? Still Looked The Same To Me

Cassandra’s gaze dropped to the jagged wound in her chest, the crimson wellspring that had fueled her divine fury. Her breathing was ragged, her chest heaving with a mixture of exhaustion and a hatred so concentrated it felt like it could ignite the very air.

"I have been preparing for this fight for months," she hissed, her voice trembling with the sheer indignity of her situation. "I built the constructions... I perfected the Blood Oath coordination..."

"Every waking moment, every ounce of my soul was poured into crafting a cage that could hold a god. And you..." She looked up at him, her eyes flashing with a murderous, humiliated light. "You walked through my masterpieces with nothing but your bare skin..."

"You caught my blade with your hands as if it were a child’s toy. And then, you had the audacity to tell me when my fuel would run out..."

"You didn’t even look like you were fighting, Lustful Villain, but you looked like you were taking notes."

"Because I was," Rex replied, his voice a smooth, infuriating purr.

He didn’t offer a defense; he offered a confirmation, his smugness acting as a second layer of armor that no blade could pierce. He stood there, relaxed and utterly unbothered, a predator watching a beautiful, angry bird flap its wings in a cage of its own making.

Cassandra closed her eyes for a single, agonizing second.

When she opened them, the atmosphere in the observation chamber shifted violently. It wasn’t a change in her energy or the visible output of the Blood Oath; it was a change in the very essence of her presence.

The professional, tactical layer of her consciousness—the part of her that had been trying to solve the "problem" of Rex—had been stripped away, leaving behind something raw, ancient, and terrifyingly singular. The part of her that believed the encounter was a duel had died.

This was no longer a combat exchange. It was a reckoning.

"You asked me to come at you again," she said, her voice dropping to a low, lethal calm that was far more frightening than her previous screams.

"Yes," Rex said, his eyes narrowing, his predatory instinct finally sensing the change in the wind.

"So? What are you waiting for?" He didn’t lose his smirk, but it sharpened, becoming the grin of a man who had finally been offered a real challenge. "I’m still not bored yet because I want to see more!"

"I’m going to," she promised, a dark, manic energy beginning to swirl around her. "But not with the tricks you’ve already seen... and not with the geometry you’ve already solved."

Rex tilted his head, his gaze sweeping over her with clinical precision. "Hoh?"

"You have a reserve," he noted, his voice filled with a teasing, arrogant curiosity.

"I have something I’ve never used in front of anyone," she countered, her eyes burning like dying stars. "Something I’ve been carrying since before this city even had a name."

"Something that has nothing to do with ’systems’ or ’data.’"

With a movement that was slow, deliberate, and heavy with intent, she reached behind her and drew the greatsword from her back. She turned the blade once in her hand, the Blood Oath coating catching the bioluminescent light of the chamber, turning the steel into a shimmering, visceral crimson.

She looked at Rex with the terrifying clarity of a person who had stepped off a precipice and realized there was no turning back.

"I want you to understand something before I do this," she said, her voice steady and cold.

"Then tell me," Rex said, his stance widening slightly, his body coiling like a spring, ready for the impact.

"I’m not doing this because I think I’ll win," she said, a bitter, hollow laugh escaping her lips. "I’ve been a combatant long enough to know when the math has already decided the winner."

"The outcome is determined... even though you’ve already won, Rex, and I know that you’ve always won." She stepped forward, the red aura around her beginning to scream with a new, unhinged frequency. "But I’m doing this because I need to know what my full capacity looks like against what you are!"

"As long as I fight as the Demon Queen to stop a pretender god, I am destined to spend the rest of my existence as an obstacle in the path of your construction, so I need to know the actual distance between us!"

She leaned into his space, her hatred a physical weight. "Not the managed distance you’ve calculated, but... the real one!"

Rex didn’t flinch, and he also didn’t blink. He simply held her gaze, his eyes gleaming with a dark, triumphant hunger.

"Then show me," he commanded, his voice a challenge to the heavens themselves.

In one fluid, violent motion, Cassandra drove the sword through her own chest.

"This again...? What’s with you stabbing your own chest?" Rex laughed. "But... let’s see the difference here."

The stab was not the precise, surgical strike she had used to activate her form. This was a brutal, primal act of self-immolation.

The steel tore through her sternum, a fatal, central strike that would have ended any other being instantly. The sound of the blade piercing bone and muscle echoed through the silent chamber like a crack of thunder.

A choked, horrified sound escaped Mordecai from somewhere behind Rex, a gasp of pure shock at the sheer madness of the act.

Rex did not move, and he also did not recoil. He stood his ground as the crimson explosion of her soul began to erupt from the wound, his eyes wide and burning, watching with a terrifying, beautiful intensity as she prepared to bridge the gap between them with her very life.

The blood that erupted from the self-inflicted wound was not the controlled, rhythmic essence that had fueled her earlier transformation. This was something far more ancient and far more violent.

It did not flow; it exploded. It was darker, a viscous, obsidian crimson that moved with a predatory, sentient velocity.

It did not spread across her skin with the practiced grace of a martial artist; it surged, a tidal wave of visceral power that coated her entire body in the singular, terrifying moment it took Rex to draw a single breath. The transition was not a gradual evolution; it was a violent, instantaneous reconfiguration of her very existence.

The frame expansion did not merely continue; it transcended. While it lacked the sheer, world-shaking volume of Gorvasha’s primal madness, the architecture of her power had shifted from augmentation to fundamental restructuring.

The Blood Oath was no longer just wrapping around her; it was reorganizing her at a foundational, molecular level, increasing her density until she felt less like a woman and more like a living monolith of compressed matter.

As the crimson shroud settled, her eyes underwent a terrifying metamorphosis. The deep, vibrant red of her previous form vanished, replaced by a color that defied the standard spectrum: a heavy, mineral crimson that possessed the light-absorbing quality of ancient geological strata.

It was the red of deep earth iron deposits, the red of blood that had been pressurized for eons beneath the weight of a mountain.

With a sickening, wet sound, she wrenched the sword from her own chest.

But it was no longer the same weapon. The steel had been entirely consumed, the metal itself having been transmuted by the sheer intensity of the Blood Oath.

The blade was now a jagged, pulsing shard of solidified essence, vibrating with a heat that was not thermal but metaphysical. To Rex’s heightened geological perception, the sword was screaming a frequency that sat on the razor’s edge of the primordial register, a frequency that was not quite the voice of the world but a terrifyingly close echo of it.

Rex’s eyes widened, a dark, manic glee dancing in his gaze. He didn’t feel fear; he felt the intoxicating rush of a man who had finally been given a real toy to break.

His gauntlets hummed in response, the earthen authority within them vibrating in sympathetic resonance with the weapon she held.

’Adjacent,’ his mind whispered. ’It’s adjacent to the source... And my gauntlets can work with adjacent...’

When she spoke, the sound was not merely a voice; it was a seismic event. The resonance of her previous form remained, but it was now layered with a subterranean bass that the very stones of the observation chamber caught and amplified, turning the room into a sounding board for her divinity.

"I am the Demon Queen of Blood Oath," she declared.

It wasn’t a boast or an announcement; it was a declaration of a universal constant, as undeniable and immutable as the existence of gravity or the turning of the tides. Her eyes locked onto his, burning with a hatred that had been refined in the fires of her own self-immolation.

"The form you’ve been playing with, the one you’ve been so smugly ’calibrating’..." she spat, the words vibrating through the floorboards, "was the contained version..."

"It’s also the polite version... and the version meant for operational contexts where precision is required."

She stepped forward, the ground cracking beneath her feet not from weight but from the sheer, crushing density of her presence. A predatory, jagged grin split her face, mirroring the violence of her transformation.

"Tonight... you... the Lustful Villain pretending to be god... don’t get precision..."

"But tonight, you get the truth..."
