"What was that move called?"

"What?"

"The Magecraft that completely destroyed the forest outside the Einzbern castle, along with the bounded field, and even severely damaged the castle itself."

After getting off the plane and arriving in Fuyuki, the site of the Holy Grail War, Illya finally asked the question that had been bothering her for a while, though it had only been the time it took to pack up at the Einzbern castle, leave, and fly to Fuyuki.

Because the power Ethan displayed was too astonishing, the Einzbern family believed his strength could completely crush all enemies in this Holy Grail War. Power at that level no longer required fine-tuning, and from the powerful attack spells Ethan could cast, they concluded that his cooperation with Illya was very tacit. Although they did not understand how Illya could withstand the magical energy consumption of such powerful magic, they still decided to let her depart early.

Only Illya knew that Ethan did not use her magical energy at all when casting spells. She had no idea how this was possible. The knowledge she had learned from the Einzbern family told her this was abnormal, but she chose to keep this secret.

However, that powerful magic... she wondered if she should still call Ethan a magus. Given the terrifying power he had shown, calling him a magus felt a bit insulting.

"You're asking about that move?"

Meteor shower? Flying fire meteor? Falling meteor? Obstacle Quaking Star?

"Actually, it doesn't have a name. It's just summoning a large rock at random, then accelerating it, accelerating it, accelerating it, and after accelerating it to a certain extent, transferring it above the forest and dropping it. That's all."

"That's all...?"

If Illya had not been a powerful magus who understood how incredibly difficult such a seemingly simple thing was, she might have believed Ethan's nonsense.

"Magecraft of that level is just a snap of your fingers for you?"

"Roughly."

Ethan was not exaggerating. Since his spellcasting relied mainly on manipulating mental power and magical energy, any physical movement was irrelevant. Whether snapping his fingers, standing still, or even jumping around doing a Swan Lake dance, it was all fine as long as it did not affect his control over mental power and magical energy.

"Then, if you were to go all out, how powerful a spell could you cast?"

"Well..."

Sitting in the luxury car prepared by the Einzbern family, Ethan looked at the distant, peaceful city while thinking about how to answer.

"Since I rarely cast spells at full power, I am not sure either."

Illya suddenly understood why this person had not left behind any stories, legends, or magic books to become a Heroic Spirit. Becoming a Heroic Spirit at this level of strength was not surprising at all.

The only strange thing was why this person had not left behind any legends or stories. Was it because he was too powerful, so his experiences were deliberately erased by certain people?

She could not have imagined that the reason Ethan had not left legends was because he was not from this world at all.

The car only circled the edge of the city, not driving directly into Fuyuki. It followed the city's edge into a suburban forest.

"This is Einzbern property, including the surrounding forest, which is protected by a bounded field. Of course, a bounded field of this level probably does not concern you."

"Mm."

These spells seemed crude and fragile in Ethan's eyes. He did not even need to actually cast. A thought was enough to destroy all these bounded fields.

"You should be very clear about the Holy Grail War, right?"

Knowledge of the Holy Grail War existed in the minds of every summoned Servant. However, Illya was not sure about this Servant named Ethan, so she asked again after arriving in Fuyuki.

"The Einzbern family decided to summon a Berserker precisely because they could ignore the Heroic Spirit's will and focus on obtaining the Holy Grail and winning this war."

But now Ethan was not mad. Although he held the Berserker Class, the Einzbern family had no ability to add Mad Enhancement to him. If they really tried to do that, the Einzbern family could say goodbye to this world. A larger pit would appear next to the huge pit at their doorstep.

"So, I want to know what wish you want to achieve."

It was best for Master and Servant to reach a consensus. Otherwise, if they both hid their intentions, their otherwise powerful combat strength could not be fully utilized, and the mission would end in failure.

"Wish?"

Ethan shook his head.

"You don't need to tell me the things used to fool outsiders. I know the true nature of the so-called Holy Grail War."

The Holy Grail War's claim of being able to grant any wish was originally just a gimmick to attract outsiders and deceive Heroic Spirits.

Its essence was a magical ritual to create a hole between the Root and the present world, aiming to achieve the Third Magic, materialization of the soul, also known as Heaven's Feel, a magic that allows humans to gain immortality.

As for fulfilling any wish, for magi, after breaking through the wall between the Root and the present world, they gain nearly infinite magical energy. For magi, this is indeed a universal wish-granting machine that can fulfill any wish.

But this is different from truly being able to achieve any wish. Wishes that cannot be achieved through sorcery or even magic absolutely cannot be realized.

Furthermore, the Holy Grail is currently polluted. The magical energy flowing out through the hole created by it is also polluted. This is the famous black mud, and if one attempts to use this polluted magical energy to make a wish, all wishes will be distorted.

"You know the truth about the Holy Grail War?"

"A special ritual performed to complete a certain magic, using beings like Heroic Spirits to create special bombs to blow a hole in the wall."

Illya was truly shocked this time. She never expected Ethan to know the true nature of the Holy Grail War.

"Since you know, why did you still respond to this summoning?"

The so-called bombs were these Heroic Spirits. Any Heroic Spirit who knew the truth would be unwilling to be manipulated by human magi in this way.

"I have some other things I need to do."

Ethan casually took some whiskey from the small refrigerator in the car. He wanted a drink, but it was all alcohol.

"So young, yet you brought so much alcohol."

"My actual age is not young anymore."

The topic shifted, and Illya did not press further. It was enough to confirm that Ethan did not want to achieve any wish through the Holy Grail.

"Then you should eat properly and drink less of this stuff that is bad for your health. Do you want to look like an elementary school student forever?"

Illya suddenly felt a throbbing in her forehead. She knew she would not grow any further and did not have much life left, so she should not care. But the way this person spoke still made her very angry.

As a result, her frustration had not completely subsided by the time they reached their destination, a castle in Fuyuki's suburbs. She could only tell Sella and Leysritt to move their things in and thoroughly clean the castle.

She was not planning to go inside until it was clean.

"You want to go out for a walk?"

Ethan also had no interest in going inside to eat dust. He stood at the main gate, looking at the nearby forest. The road ahead led directly to Fuyuki, but it was far. Walking into the city without a car would take a long time.

"After all, we will be fighting here. It is normal to get familiar with the battlefield in advance, right?"

In fact, she wanted to visit someone, but she was not planning to tell Ethan. She did not know how to explain it either.

"Actually, it doesn't matter whether we look or not. It makes no difference to me fighting anywhere."

If it was an open area, he would cast spells freely. If it was in the city, to avoid harming civilians, he would usually open a Mirror Dimension and pull his opponent in.

Either way, his fighting style would not change.

Of course, he could also choose not to fight, since his purpose here was to find that intruder. But he thought an excellent Transmigrator would definitely find ways to get involved in the plot.

When that person discovered Ethan, this inexplicable intruder, they would definitely make contact proactively, or try every means to eliminate this potential competitor.

In other words, as long as Ethan showed up and participated in this game, his target would come to him. He would not need to search, which was why he had been taking his time and chatting with Illya since arriving in this world.

"If you want to clear your head, just say so. I actually want to take a look too."

"..."

Illya felt the throbbing in her forehead start up again just as it had calmed down. She decided to ignore Ethan and walked to the garage alone, chose a car, and prepared to get in.

She had just pulled the door open and had not gotten in when a force from behind pulled her aside.

"What are you doing driving a car, kid? Sit over there."

Then Illya watched Ethan sit in the driver's seat, skillfully find the key in the sun visor, insert it, and start the car.

"What? Don't you want to go out for a drive anymore?"

Although she seriously doubted Ethan's driving skills, Illya still got into the passenger seat. However, two seconds later, she regretted it.
