"〈Wyvern Summon〉!"
As Rozen's entire body surged with magic and he used the long-forgotten 〈Summoning Technique〉, instead of a magic circle appearing around him, there emerged a mist of blood.
The blood mist transformed above Rozen's head, quickly taking the shape of a two-legged wyvern.
"Roar!"
The wyvern flapped its wings and let out a furious roar.
Upon seeing this wyvern, everyone present showed expressions of astonishment.
"Senpai...!?"
Yukina exclaimed in disbelief.
"A beast vassal...!?"
Sayaka Kirasaka also became bewildered.
"He summoned a beast vassal...!?"
Even Vatler's expression changed unexpectedly, showing extreme surprise.
"Nichiyo..."
La Folia Rihavein seemed to be taken aback by the unexpected turn of events, holding her breath for a moment.
Even their own side was shocked, let alone the enemy.
"A human..."
"Summoned a beast vassal...?"
The vampire and beastman standing beside Kenese Kensei couldn't believe their eyes.
"You..."
Kenese Kensei himself was astonished by the situation unfolding before him.
It wasn't particularly difficult to summon a beast vassal.
Unlike summoning spirits, which requires special qualifications and conditions, summoning beast vassals isn't that difficult; anyone other than vampires can do it.
Even the apostle could artificially create beast vassals, indicating that obtaining the power of beast vassals isn't difficult.
The problem lies in the fact that although summoning beast vassals may not be difficult, controlling them freely is another matter altogether.
Not to mention, the price of the beast vassals' life force absorption is something that no one except vampires can bear.
So, while everyone wasn't surprised that Rozen could summon beast vassals, what surprised them was Rozen's audacity to summon and use them.
Therefore, everyone was shocked and couldn't believe their eyes.
But Rozen indeed summoned beast vassals.
However, they weren't summoned from another world; Rozen transformed his own familiar within his soul into a beast vassal.
If one were to observe carefully, they would notice that the wyvern no longer had its fierce appearance and solid form like before; it had become somewhat transparent, like it was condensed from jade green gemstones.
This was the beast vassal form of the wyvern.
Since Rozen embedded genuine beast vassals within his blood and even had the top nine strongest beast vassals residing in his blood, he successfully analyzed the magical structure, will form, and existence of the beast vassals using his Mind's Eye, and ultimately managed to semi-materialize his familiar into the form of a beast vassal.
Hence, Kinu and Hokuto could relinquish their duties as guardians not because Rozen dismissed their summoning, but because Rozen could transform them into beast vassal forms, allowing them to reside in his blood.
Therefore, Rozen didn't just have nine beast vassals within his blood; he had a total of eleven.
Among them, nine were beast vassals seized from the Fourth Primogenitor, and the other two were Kinu and Hokuto, which he kept in their summoned forms within his blood so he could summon them anytime.
As for the remaining familiars, they could also be summoned in the form of beast vassals.
When summoned in the form of beast vassals, they would gain immense destructive power and immunity to all physical attacks, but their endurance would greatly decrease. Once subjected to effective attacks, they would immediately disperse.
Now, Rozen summoned his wyvern in the form of a beast vassal.
Naturally, even in their beast vassal forms, they remained Rozen's familiars, absolute loyalists engraved in Rozen's soul, incapable of absorbing Rozen's life force.
The onlookers, unaware of this fact, turned pale, but it didn't affect Rozen in the slightest.
"〈Wyvern Summon〉!"
Rozen continued to summon relentlessly, causing numerous jade green wyverns to emerge from the blood mist.
"Roar!"
"Roar!"
Before long, countless wyverns, accompanied by much stronger magical fluctuations than before, filled the sky.
"You... Are you insane...!?"
Seeing the multitude of beast vassals summoned by Rozen, even Kensei Kanesue couldn't help but exclaim.
Others had similar reactions; no one dared to believe that Rozen would be so audacious as to summon beast vassals so recklessly.
Looking at the wyverns covering the entire sky, one could only wonder if there were not just hundreds but even thousands of them.
Hundreds of beast vassals?
The life force they consumed could almost kill Rozen instantly in the next moment.
But...
"It's not over yet!"
Rozen's new power was not limited to this extent.
Under Rozen's manipulation, the hundreds of wyverns began to circle each other and eventually merged together like water.
Before long, a giant dragon, emitting a ferocious magical aura, with a size of over ten meters, appeared in the sky.
"Roar————!"
The dragon roared to the sky, its roar turning into shockwaves, expanding and overturning the atmosphere, causing it to tremble continuously.
Watching this scene...
"Fusion beast vassal...!?"
Vatler's breath caught, followed by an expression of ecstatic joy.
The others were stunned, completely dumbfounded.
So far, only Vatler could use fusion beast vassals, and yet Rozen had achieved it?
How... How was this possible...?
But even if everyone present couldn't believe what they saw and heard, the scene before them was a fact.
Rozen not only realized the transformation of his familiars into beast vassals but also achieved the technique of fusion beast vassals, becoming the second person after Vatler to be able to use fusion beast vassals.
Initially envisioned, Rozen has now fully realized it.
This is the new power that Rozen has obtained.
Now, Rozen has used this new power to merge hundreds of wyverns into one.
And because the wyvern is just sub-dragon, the dragon formed by merging hundreds of wyverns is now a true dragon.
Its strength is only at the pinnacle of tactical level.
However, in terms of destructive power alone, it is definitely at the strategic level.
Because it is a beast vassal, sacrificing endurance for destructive power naturally surpasses the tactical level.
"Go!"
Rozen pointed in the direction of Kanase Kanon, and the giant dragon roared suddenly, flapping its wings, like an arrow leaving the bow, bursting out violently.
"Kyriiiiiiiiiiiii————!"
Kanon Kanase, who was just stabilized after being blasted to Rozen's side, saw the raging giant dragon rushing towards her, immediately emitting a sharp call.
Rozen had already infused divine energy into the dragon and used space manipulation magic to connect higher dimensions with lower ones, allowing the dragon's attack to harm Kanase Kanon.
Kanon Kanase instinctively sensed this point, so instead of ignoring the enemy's attack as before, she also spread her wings and flew into the air, attempting to dodge.
"Roar————!"
The dragon, fused with hundreds of wyverns, roared angrily, spewing out scorching dragon breath towards Kanon Kanase, who was flying into the air.
The next moment, the huge flaming mass, as hot and massive as the sun, turned into a projectile and shot up into the sky.
On the wings behind Kanon Kanase, six eyes immediately reacted, emitting flashes that converged into a huge beam of light, descending from the sky to meet it.
"Boom————!"
Just like the collision between Vatler's beast vassal and Kanon Kanase's light earlier, a blast wave erupted, the sky changed color, the sea waves surged continuously, and the atmosphere kept trembling.
However, the result was different.
Vatler's beast vassal's attack was scattered because Kanon Kanase used dispelling divine energy.
But Rozen was different.
Rozen had already infused divine energy into his own beast vassal, enabling its attack to carry divine power.
So, when divine energy clashed with divine energy, the dragon's fiery breath pierced through the blast, directly blasting towards Kanon Kanase.
"Boom————!"
Amidst the booming sound, Kanon Kanase was directly hit by the incoming fiery breath, taking a direct hit.
A grand explosion appeared in the sky, causing the entire world to tremble.
"Kyriiiiiiiiiiiii————!"
At the center of the explosion, Kanon Kanase let out a painful scream.
Her body was subjected to the unstoppable burning of attacks from higher dimensions, causing her skin to start turning black and her body to become covered in wounds.
At this point, Kanon Kanase, who had transformed into a faux angel, finally began to be injured.
"Kanon!"
Seeing this, Kanon Kanase's father, Kensei Kanase, exclaimed in extreme horror.
But Kanon Kanase's fate was already sealed.
The reason why angels are terrifying is twofold: first, they can use dispelling divine energy to attack; second, they are invincible in higher dimensions, making them even threats to beings like the Primogenitors.
Conversely, as long as these two problems are solved, defeating angels is not difficult.
Now, Kanon Kanase's divine energy is being offset by the divine energy of Kinu and Gyokuto that Rozen continuously infused, making it impossible for Kanon Kanase to break free.
The outcome is decided at this moment.
Rozen has defeated the angel and successfully thwarted Kensei Kanase's plan.
