"Caster!"
Rozen's voice echoed loudly.
"Right here!"
Caster immediately leaped down from the rocky platform, slicing through the air like a bullet, and landed in front of Rozen.
"Boom!"
A burst of energy erupted around Caster. Unprecedented massive amounts of magical power surged within Caster, painting a ferocious smile on his face filled with fighting spirit.
The first to react was Archer.
"Though I don't know what you're planning, you won't succeed!" Archer raised his bow and released a large amount of magical power. While not as excessive as Caster at this moment, he pushed his limits as a singular servant.
Next, Archer created a sword.
Using Projection Magic as his means, Archer could create intricate fantasies that human magicians could never achieve, even projecting Noble Phantasms if he had an unlimited supply of magical power.
Even though the rank of the projected Noble Phantasm would decrease, as long as his magical power remained inexhaustible, Archer's arsenal would be limitless.
Therefore, all of Archer's arrows were Noble Phantasms.
He refined the created "swords" into "arrows" and shot them out, detonating the stored magical power and faith within the arrows, converting them into terrifying destructive power capable of devastating even buildings.
This was the reason why Archer's shooting power was astonishingly high, a fighting style that only Archer could employ, an extremely extravagant fighting style.
Naturally, under this fighting style, the higher the rank of the "sword" he projected, the greater its destructive power.
Now, Archer had crafted the highest-ranked Noble Phantasm, capable of unleashing an A-rank level of power with his shot.
Archer was about to unleash his shot when a sudden pain erupted within his body.
The ethereal owl transformed into a phantom once again and entered Archer's body, causing his face to turn pale.
"You stay put there!" Rozen reached his hand towards Archer.
With nearly infinite magical power supply, Rozen no longer needed to hold back. Even the magic-consuming phantasmal beasts could be extravagantly utilized without any hesitation, making their attacks swift and fierce, displaying a much greater interference effect than before.
Although they still couldn't separate the Servants' spiritual bodies from the present world, at least Archer was temporarily immobilized.
As for Saber, she seemed indifferent to whether Archer was assisting or not.
After all...
"No matter what you plan to do, it's futile in the face of the power of this holy sword."
Saber stirred up a terrifying flow of magical energy and raised the liberated holy sword high once more.
Next, all Saber had to do was swing the holy sword, and that most fearsome strike would evaporate everyone.
However...
"Let me seal your Noble Phantasm for now!"
Rozen turned the tremendous magical power into a miracle and activated the most extensive magic.
In the next instant, accompanied by explosions, countless magical ants seemed to hatch from their eggs, emerging from the underground of the large cavity.
How many magical ants emerged?
Dozens?
Hundreds?
No!
There were at least thousands!
Innumerable magical ants swarmed toward Saber like wild beasts.
Using her Instinct skill, Saber naturally sensed the magical ants appearing from underground, but this time, she couldn't dodge.
"Since you can detect the attack, then I'll make sure you have nowhere to hide!"
With Rozen's shout, countless magical ants filled the entire large cavity, leaving Saber with no space to evade.
"...!?"
In an unavoidable situation, Saber promptly jumped like a rocket, breaking through the ground, and leaped into the air, avoiding the swarming magical ants.
Even Saber didn't notice.
"Clang!"
On the surface, among the countless magical ants, eighteen of them suddenly lit up on their backs.
Astonishing magical fluctuations emanated from those eighteen magical ants, causing Saber to change her expression.
It was only at this moment that Saber saw it.
On the backs of those eighteen magical ants, runic inscriptions began to appear.
They were very simple yet extremely profound, seemingly simple strokes but incomprehensibly intricate eighteen characters.
"Could it be...!?"
Saber quickly turned her head and looked in Caster's direction.
"Found it? Too bad, it's too late!"
Caster, who had been continuously increasing his magical power, showed a sinister grin.
"Savor the power of the Primordial Rune I acquired from my master!"
-----〈Primordial Rune〉.
But that's not an ordinary runic script.
In modern times, there are magicians who use "Rune Magic," but the runes used in these magic are derived from the original runes and hold mysterious significance.
The Primordial Rune, on the other hand, consists of the eighteen most ancient and original characters that the Norse god Odin obtained in the primeval times, truly embodying the secrets of the divine era.
Caster's Noble Phantasm unleashes the power of all eighteen Primordial Runes simultaneously.
This grants it the ability to inflict massive damage to the enemy and nullify all their enhancement effects. It forcibly reduces their ability parameters by one level. In cases where the enemy activates a continuous-use Noble Phantasm, it can even halt the effects of that Noble Phantasm for a period.
That's the effect of Caster's Noble Phantasm, graded at the highest level, A.
Moreover, like Saber's holy sword, it is an Anti-Fortress Noble Phantasm.
"This is a powerful attack meant for fortresses, which should be challenging to use so casually. But with the extraordinary quality of this Master and such an outrageous amount of magical power to utilize, if I don't put up a bit more effort, I'll be letting down the little guys who fought so hard!" Caster exclaimed loudly.
"Come on! Unleash all your power!"
Caster released his Noble Phantasm.
"〈Ochd Deug Odin (Great God's Inscription)〉!"
The original runic characters engraved on the backs of the eighteen magical ants lit up with a dazzling radiance in the blink of an eye.
The brilliance filled the entire large cavity, revealing layers of mysterious magical patterns that formed what seemed like a magic circle, radiating wave after wave.
"In that case...!"
Saber raised the jet-black holy sword.
Facing the highest-level Anti-Fortress Noble Phantasm, the only option was to strike back with an even more potent Anti-Fortress Noble Phantasm.
By doing so, the holy sword, which could burst into a++ effect in an instant, would undoubtedly surpass Caster's Noble Phantasm and achieve victory from defeat.
Unfortunately, Saber couldn't succeed.
Didn't Rozen say it earlier?
"I told you I would seal your Noble Phantasm!"
The phantom of the owl approached silently.
Even though Saber noticed it while leaping into the air, this time there was no way to avoid it. She could only watch helplessly as the owl's phantom entered her body.
Thus, Saber's Noble Phantasm stopped being unleashed.
Only Caster's Noble Phantasm continued to radiate, covering the entire large cavity.
