-52- Training? To my Limits?

The Grand Hollow.

That was a huge cave located deep within a mountain named Circle Mountain.

As the name suggested, it was an immensely spacious hollow.

After a long journey following Archer's retreat, Rozen and his group arrived at the entrance of the tunnel leading to the Grand Hollow.

"Finally here..."

Seeing the vast cave, Rozen collapsed on the ground, seemingly drained of all energy, looking utterly despondent.

"Hey hey, it's just a twenty-minute walk. How can you be so exhausted? Your stamina seems to be quite lacking compared to other magicians."

Caster was a bit dumbfounded, unable to comprehend Rozen's condition.

"What do you mean 'just a twenty-minute walk'? It's not easy to keep up with the pace of you Servants!" Rozen retorted vigorously.

It should be noted that the Grand Hollow was located within the depths of Circle Mountain, and finding the passage leading to it required traversing quite a long mountain path. Although for others, it might not be that difficult, but for Rozen, it was a considerable distance and effort.

Caster scratched his head, a little puzzled. "This is the price of talent, isn't it? You have exceptional intelligence and magical aptitude but lack physical strength. If my master saw this, she would probably be disheartened."

Rozen's reaction to this remark was overshadowed by Mash's curiosity. "Is Mister Cú Chulainn's master the Queen of Witches, Skadi, who resides in the Shadow Border and can even slay gods?"

Caster didn't seem enthusiastic about being referred to by titles or using honorifics. "Let's skip the formalities. I'm not used to them. Just call me Caster; that will do."

Caster first snorted and then smiled.

"That's right, compared to me, my master is truly terrifying. There are very few in the world who can match her."

She is the one who trained Cu Chulainn, the strongest warrior of Ulster, so she is no ordinary person.

She resides in the Celtic realm known as the Land of Shadows, considered to be the queen of the underworld, accepting the dead and lost souls.

She is incredibly talented, nurturing numerous warriors and magicians, becoming the teacher of many renowned heroes throughout history.

She possesses combat skills that can rival gods and wields magical techniques that even many gods can't comprehend. Though she has a human form, she transcended into the realm of gods as a mortal, killing countless undead, humans, and even deities.

Due to this, the great witch is bound by a curse that entangles her entire life, making her unable to die, forever living in the Land of Shadows. Only if the world is destroyed or consumed by chaos will she find peace.

This legendary figure is none other than Scáthach, the eternal queen and ruler of the Land of shadow."

"A person who can train and teach someone like Caster..." asked Mash with curiosity. "What kind of person is she?"

"Well," Caster scratched his head, looking somewhat troubled. After a while, he continued, "She is a terrifyingly powerful sage who can perceive the causes and consequences of everything in the world with her keen eyes. However, she rarely speaks about herself. Compared to us disciples, her abilities are at the highest level, allowing her to easily see through the essence, temperament, and abilities of others. She values talent greatly."

Due to Skadi's exceptional abilities, many legendary heroes and warriors were her disciples, trained to become great figures in history.

"Her greatest wish is to train someone capable enough to kill her and free her from the curse of eternal life. Unfortunately, so far, no one has succeeded. Therefore, she is still living in the Land of Shadow. If you ever have a chance to go there, you might see her, but I doubt anyone would be foolish enough to go there."

Rozen's interest was piqued, but Olga Marie was quick to respond, "In modern times, the connection to the Land of Shadow has ceased. There are no means to reach there. Even if it were possible, no one would be stupid enough to go there. The Land of Shadow is the realm of the dead, and the chance of survival for a living person is almost zero. It would be like seeking death."

However...

"Surviving there would only be the beginning. Otherwise, you won't be qualified to be guided by my master."

Caster's nonchalant remark left Mash and Olga Marie speechless.

"Perhaps the Master could do it. If you have the time, you should give it a try. Seeing such a talented person like you in such a state, my master would definitely not give you a moment to rest and train you to your limits."

Upon hearing this, Rozen couldn't help but shudder. If it were about practicing magic, it might be acceptable, but physical training was something he absolutely would not be interested in!

But why do I have a feeling that this might actually happen in the future? It must be an illusion!

"Let's send a familiar into the large hollow to check the situation first!" Rozen promptly changed the subject and prepared to summon a familiar.

However, Caster stopped Rozen this time. "Don't waste your magical energy. This approach might work against Archer, but it won't be effective against Saber."

Caster had previously fought Saber once and even survived a strike from Saber's Noble Phantasm, barely escaping with his life. "After taking that strike from the Noble Phantasm, anyone should be able to recognize Saber's true identity," Caster explained.

Thus, Rozen and the others already knew Saber's true name from Caster and were astonished and shocked for quite some time.

Since sending a familiar into the hollow would be futile, Caster proposed a direct and aggressive approach. "Let's attack directly," Caster suggested.

Rozen, after brushing off the dirt from his body, stood up and replied, "Then let's charge in!"

Under Rozen's guidance, the group charged into the large hollow, where the most formidable presence had already been waiting for them.

Upon seeing Saber's true form, Mash and Olga Marie both groaned in disbelief.

Caster gripped his staff tightly, preparing for a fierce battle.

Taking a deep breath, Rozen suppressed the emerging cold sweat. All of this was due to the overwhelming and astounding magical power released by their adversary.

"So you're here."

As a light and cold voice echoed, the most formidable enemy in this singularity stepped forward, each step exuding power and strength, appearing before them.
