"Boom...."
Above the vast ocean, waves rolled one after another, surging and churning everywhere, making the entire sea seem boiling, extremely restless.
Dazzling arcs of electricity still danced across the surface of the sea.
Scorching magma sank into the depths, causing the seawater to evaporate as if being steamed, releasing countless steam and hot air.
Amidst this scene of destruction, Rozen's figure flickered out of space and descended towards the sea, finally stepping directly onto the surface of the water, rising and falling with the waves.
This was the result of Rozen using jujutsu.
The moment Rozen fell into the sea, he chanted a spell that allowed him to walk on the water's surface, preventing himself from sinking.
The beast vassals summoned by Rozen had all returned to his blood, disappearing without a trace.
As Rozen bobbed along with the waves, he used Spirit Vision, Heaven's Eye, and Mind's Eye together to peer around.
After all...
"This level of power shouldn't be enough to kill you, Giada."
Rozen shouted towards the undulating sea.
At least, Rozen didn't believe that Giada, one of the three Primogenitors who had become a true ancestor from the moment they existed and had survived until now, would die from just that one blow.
Even if it was a strike that could pierce through space, it didn't matter.
And indeed...
"Quite impressive."
Giada's voice came directly from space.
Rozen, who had activated Spirit Vision, Heaven's Eye, and Mind's Eye simultaneously, naturally sensed that the surrounding space was filled with strange magic and fluctuations as Giada spoke.
It wasn't that space was being controlled, but that space itself was being replaced.
Rozen felt as if he had suddenly been drawn into a different space, enveloped by this space.
This was...
"The space beast vassal you've been using, right?"
Rozen addressed the owner of this space.
"Yes."
Giada's figure appeared silently in front of Rozen, smiling at him.
"This space itself is my beast vassal, just like Camaxtli and Xiuhtectli."
Most of Giada's summoned beast vassals seemed to be phenomena themselves.
Just like beast vassals with living weapon forms, the thunderclouds that manipulated lightning, the scorching volcanic flows, and this entire space were all beast vassals of Giada.
However...
"In terms of sheer power, my beast vassals alone might not be a match for the fourth Primogenitor's beast vassals."
Giada's voice was full of delight.
"Although you're just a human, you completely control the fourth Primogenitor's beast vassals, surpassing the original in both proficiency and power usage. Even in terms of dominance and manipulation, you far surpass the original. Even I find it admirable."
However...
"It's a pity that you only have ten beast vassals. If you don't retrieve the remaining two, you won't reach the complete state of the fourth Primogenitor."
Even at this point, Giada still pursued the strength of her opponents, which was truly admirable.
However...
"If I really had all twelve beast vassals, wouldn't there be no need to fight?"
Rozen smirked.
If Rozen truly reclaimed all twelve beast vassals and reached the same level as the fourth Primogenitor in his complete state, Giada wouldn't stand a chance.
Otherwise, how could the fourth Primogenitor be known as the strongest vampire in history?
Moreover...
"I'm not limited to just using beast vassals for combat."
With these words...
"————"
Rozen suddenly formed hand seals, chanting a spell that caused the surrounding sea to surge as if it had been completely brought under control, suddenly rising into towering waves.
It was the Water Heaven Art.
"————"
Rozen completed the chant for the Water Heaven Technique, causing the entire expanse of the sea to seem completely dominated, churning into endless tidal waves, rising high into the air.
In the past, in the waters of the third singularity, Rozen summoned a mythical tsunami in this manner, engulfing the enemy fleet and retrieving the Holy Grail.
In an environment where there is an endless supply of water, the power of Water Heaven Art will skyrocket to an astonishing level.
At present, a tsunami surged forth like a natural disaster, engulfing towards Giada's direction.
"So this is your own power!?"
Giada, not surprised but rather pleased, raised her hand and once again summoned a volcanic-like surge of scorching hot lava, dyeing the surrounding sea into magma, surging out tumultuously to meet the incoming tsunami.
"Boom!"
The tsunami collided with the fiery waves.
The confrontation between water and fire caused water vapor to erupt completely, covering the entire area.
Over the ocean, a large area was completely covered by hazy steam, making it impossible to see one's hand in front of one's face.
Of course, this had no effect whatsoever on Rozen and Giada.
Rozen could cover the surroundings with Heaven's Eye, fully aware of everything happening, and couldn't lose combat capability just because his vision was obscured.
Giada, on the other hand, controlled this space as her Beast Vassal, through which she could freely use spatial transfer and even move on the sea surface like Rozen.
"Now that you've shown this move, let me show you mine."
After saying this, Giada suddenly appeared in front of Rozen.
As her Beast Vassal, this space was completely manipulated by Giada, not only able to freely use spatial transfer but also able to move on the sea surface like Rozen.
"Then, here I come!"
Giada shouted, then suddenly dashed towards Rozen like an arrow leaving the bow.
Before that, Rozen's hand had already grasped a talisman, ready to face Giada's attack.
