-57- Standing on equal footing

"What...!?"

"This...!?"

Suddenly, a surge of magical energy storm surprised everyone present, and they all turned their heads to look at Rozen's direction.

"Ah..."

Feeling the massive influx of magical power through his body, Rozen transferred it into Mash's body.

"This magical power..."

Saber, holding the black aura sword, observed the tremendous magical power emanating from Rozen and Mash, sensing power that was no less than her own.

The immense and overwhelming magical power on Rozen and Mash made Saber's eyes shimmer with seriousness.

With just one sentence, Rozen responded:

"Go, Mash!"

That was the signal for an attack.

"Yes!"

Without hesitation, Mash followed Rozen's command, raised her shield, and charged towards Saber at an incredible speed, leaving a trail of destruction in her path.

"....!?"

Only then did Saber react, quickly raising her black aura sword again, ready to unleash her Noble Phantasm.

"Thud!"

A loud impact echoed 0.1 seconds later.

Mash's heavy shield struck Saber, who had managed to protect herself with the black aurora sword, but the powerful force still sent Saber flying.

Adjusting her position in mid-air, Saber skillfully neutralized the impact and landed on the ground, sliding a fair distance.

"It... it worked!"

The unexpected outcome surprised even Mash.

"Great!"

Caster cheered from the rocky platform.

"Did you gain more strength?"

Archer's expression turned serious as he looked towards Rozen.

Even Saber gazed at Rozen, lowering her voice, "What did you do?"

With a smirk, Rozen casually replied, "Don't be so surprised. This isn't my magical power; it's borrowed from somewhere else."

"Borrowed?" Saber first seemed puzzled, but then something seemed to dawn on her, widening her eyes.

Seeing her reaction, Rozen's smile grew even wider.

"It seems you've figured it out. Yes, this magical power comes from the city of Fuyuki, right beneath our feet."

That's the origin of Rozen's terrifying magical power.

When they set out earlier today, Caster had already mentioned it.

"Saber is in that mountain, and the ritual magic circle of the Holy Grail War is located in a huge cavity within that mountain."

Yes.

The ritual magic circle of the Holy Grail War, also known as the "Greater Grail."

It is the foundation of the Fuyuki City's Holy Grail War, establishing the conditions for the ritual to take place. It not only includes the system for summoning Heroic Spirits, granting Command Seals, and selecting Masters, but also absorbs and stores magical energy.

Thanks to it drawing the necessary magical power from the ley lines of Fuyuki City, the Holy Grail War can be held every sixty years, storing enough magical energy to summon Servants, form Command Seals, and fulfill wishes.

Originally, this magical power should have been provided to the seven Masters and their Servants in the Holy Grail War, allowing the former to gain Command Seals and the latter to be summoned.

However, with the interference of the foreign "Holy Grail," Saber has almost broken free from these constraints. All the magical power now comes from the "Holy Grail," not the "Greater Grail."

Even the defeated Servants like Lancer, Archer, Rider, Assassin, and Berserker, have completely severed their supply from the "Greater Grail." Currently, the only Servant remaining reliant on the "Greater Grail" is Caster.

So, after witnessing Saber's tricky situation and surviving Archer's attack, when Rozen saw an arrow fired by Archer that landed behind him, creating a pit in the ground, he thought, "Since the magical energy of the 'Greater Grail' is completely unused, why not make use of it myself?"

With a slightly pale face, Rozen smiled at Saber.

However, the content of Rozen's words did not elicit laughter.

In other words?

"You extracted the stored magical energy from the 'Greater Grail'?"

Saber's expression finally changed.

Not only Saber, but even Archer, Caster, and Olga Marie also had their expressions change.

Especially Olga Marie, she almost reflexively blurted out, "How is that even possible!?"

That is something anyone would think.

Because it's not something that can be easily done.

After all, the "Greater Grail" in Fuyuki City is the very foundation of the Holy Grail War, with its established magic circle. Trying to extract the stored magical energy from this magic circle is equivalent to manipulating it with one's own power

If one person could manipulate this magic circle, wouldn't it mean that they could use the power of the magic circle alone, even summoning Servants without relying on anyone else?

But that's simply impossible.

It is precisely because the magic of "Heroic Spirit Summoning" is so complex and extensive that it is beyond human capability. That's why Chaldea created the Heroic Spirit Summoning System, allowing the "Fate" system to handle the task. The same applies to the Holy Grail War in Fuyuki City, where the "Greater Grail" takes full responsibility.

Now, Rozen somehow interfered with the composition of the "Greater Grail" and extracted magical energy from it using his own abilities.

Such a astonishing act naturally alarmed everyone.

However, what these people didn't know was that Rozen was also taking a risk.

He touched the ring of "Miracle" worn under his glove and felt grateful for the knowledge it had bestowed upon him. It granted him all the knowledge of summoning rituals throughout history.

"If I hadn't known the structure of the 'Heroic Spirit Summoning,' I wouldn't have been able to do this."

In other words, Rozen managed to interfere with the "Greater Grail" system because he possessed the knowledge of "Heroic Spirit Summoning" rituals, including the construction of magic circles and ritual components.

Even though Rozen still couldn't achieve the miracle of "Heroic Spirit Summoning" entirely on his own, since the ready-made magic circle was right in front of him, he could at least manipulate it to some extent and extract the stored magical energy from it.

Therefore, even before Saber and Archer launched another attack, Rozen had already started preparing. He immersed his consciousness in the great cavity and ultimately discovered the presence of the "Greater Grail" beneath the rocky platform where Caster and Archer were fighting. He quietly infused magical energy into it, constructing a temporary route to extract the magical energy from within.

"Now, there's no need to worry about a lack of magical energy here. Finally, we are standing on an equal footing for the battle."

As he accelerated the extraction of magical energy, Rozen's lips curved slightly.

"So, it's time for you to experience the trump card we have prepared.".
