-1198- Not necessary

"Boom..."

The atmosphere rumbled.

The sky rumbled.

The ground rumbled.

The ocean rumbled.

Standing on the rocky island where the prison barrier was located, the third primogenitor named Giada unleashed her strongest level of magic, creating a column of energy that soared into the clouds.

This wasn't the first time Rozen had seen such a sight.

The spectacle of being able to squander such terrifying magic power was witnessed by Rozen from the original during the "Blazing Banquet" half a year ago.

From this perspective, Giada was indeed worthy of being a primogenitor. Although her magic power might not match that of the fourth primogenitor, who was hailed as the strongest vampire in history, she was still on par with the Ley Lines at.

Facing this level of power, Rozen could remain calm, but others might not be able to.

"What a terrifying magic power...!"

"Is this a primogenitor...!?"

Yukina and Sayaka were struggling to maintain their balance as the storm of magic power lifted them, gritting their teeth to endure.

"Third primogenitor...!"

"Monster...!"

Broodt and Kiliga also had changing expressions as they struggled to maintain their balance in the storm of magic power.

La Folia and Jiriora showed different reactions.

"So this is indeed a battle worth watching."

La Folia's body was filled with huge spiritual power, seemingly protected by the spirits, maintaining her intact form, her gaze firmly fixed ahead.

"Is that Lady Giada's power...!?"

Jiriora only felt her blood boiling.

As a pure-blooded vampire who inherited the blood of the third primogenitor, for Jiriora, Giada, as the third primogenitor, was not only the king she should pledge allegiance to, but also an ancestor-like existence.

Now that the other party was freely wielding power in front of her, as a vampire connected by blood, Jiriora's blood couldn't help but boil.

While enduring this feeling, Jiriora stared at Giada, bathed in the terrifying storm of magic power, with a mixture of joy, envy, and jealousy that others couldn't easily detect.

As for Kojou and Avrora, they were taken away by Natsuki.

"You two! Don't leave my side!"

Natsuki released the "Lawbinding Shackles", wrapping them around Kojou and Avrora's bodies, and reluctantly used space manipulation magic to guide the incoming storm of magic power to another space, resisting the onslaught.

"What... What kind of power is this...!?"

"Nichiyo...!"

Kojou and Avrora shouted, one in astonishment at the current situation, and the other looking at Rozen with a worried expression.

"Don't worry, Nichiyo will be fine."

It was actually Natsuki who said this, although her gaze never left Rozen, she said so confidently.

"Since that boy dared to challenge the third primogenitor directly, it proves that he has the ability to deal with her. He's not a reckless person. We just need to take care of ourselves."

This statement from Natsuki sounded like it was for others to hear, but also like it was for herself.

"Now is not the time to worry about what will happen to the prison barrier."

Looking at the prisoners lying all over the ground, almost indistinguishable as to whether they were corpses or living beings, Natsuki sighed silently.

For Natsuki, the breaking of the prison barrier was a tremendous event.

But now, compared to the inevitably world-class battle in front of her, the matter of the prison barrier was trivial.

After all, no matter how vicious the prisoners in the prison barrier were, they were not as vicious as the primogenitors who had lived for endless years, even building empires.

And even the primogenitors had to exert all their strength in battle. The future course of events was unpredictable even for Natsuki.

Natsuki could only strive to recover as quickly as possible and shake off her weakness.

Only by regaining her strength could Natsuki have the confidence to deal with any situation.

Everyone was bathed in the storm of magic power stirred up by Giada, unable to focus on themselves.

And in this situation, although Rozen also released his magic power, compared to Giada's released magic power, it was pitifully small.

However, only Rozen could stand steady under Giada's magic power, even though his clothes and hair rustled in the storm of magic power, he still just stared at Giada.

Giada smiled suddenly, and the magic power surging up from her body stirred the dark clouds in the sky, making the sky seem to lower down, earth-shattering.

No, it's not like.

In the sky, those dark and oppressive clouds did indeed descend.

Moreover, it wasn't just ordinary clouds, but extremely dark ones, flashing with lightning and thunder throughout.

That is...

"Beast Vassal..."

That's right.

Those densely packed dark clouds are Giada's Beast Vassal.

"Come, let me see your Fusion Beast Vassal."

Giada summoned her own Beast Vassal while urging Rozen eagerly.

Obviously, in Giada's eyes, if Rozen wanted to confront her, he had to use a Fusion Beast Vassal at least.

Because Rozen did not have primogenitor-level magic power, and didn't even have the magic power of an ordinary old-generation vampire.

In this situation, where his Beast Vassal's power would be greatly reduced, and could only be enhanced by fusing with it, it was no longer a secret.

For this reason, Giada hoped that Rozen could become stronger as much as possible, which is why she intervened in this event with No. 6 and sent a new Beast Vassal to Rozen.

However, Giada didn't know at all that the gift she sent was far greater than she imagined.

Fusing Beast Vassal is the only way to contend with her?

"Not necessary."

Rozen declared so in front of Giada.

"At this level, you're not qualified to let me use Fusion Beast Vassal."

As soon as these words were spoken, Giada was stunned.

But...

"Cone forth."

Blood mist sprayed from Rozen's body.

"The Fifth Beast Vassal——Regulus Aurum."

At Rozen's call, a new Beast Vassal appeared from the blood mist.

That was a suit of armor formed by dazzling lightning, enveloped in thunder, and presenting a giant lion with a golden hue all over.

The thunder lion had a size of a dozen meters, and the magical and powerful fluctuations emanating from its body were completely beyond those summoned by Giada's beast vassal, even surpassing them.

"What?"

This situation caught Giada extremely off guard.

But...

"Now is not the time to be stunned, Your Highness."

Rozen spoke with a smirk.

"This is the power you wanted to see. Open your eyes and look at it."

With that, the thunderous lion behind Rozen roared loudly.

"Roar!"

In the earth-shaking roar, the thunderous lion transformed into lightning and shot towards the direction where Giada was.

Wherever it passed, the atmosphere was evaporated by the ultra-high current, causing the dazzling electric arcs to scatter everywhere, shattering the surrounding earth.

The power of this attack was indeed a genuine disaster-level, a power only the Primogenitors could possess.

Giada felt a fatal threat from this attack, but she was both shocked and delighted.

"Go—〈Camaxtli〉!"

At Giada's command, a tremendously thick thunderbolt descended from the thunderclouds above her head, sweeping towards the thunderous lion of lightning.

"Boom!"

Two incredibly shocking lightning bolts collided heavily in the sky above the prison barrier, causing countless lightning bolts to fly around, and shockwaves swept everything within tens of kilometers, shaking the surroundings.
