Across the heavens, I am the Avatar Sword Master

Emiya Kiritsugu took a deep breath and suppressed the anxiety rising in his throat.

Now is not the time. Acting rashly will only put Illya in danger.

If old man Yubusta Kuhaid decides to turn against him.

Maiya, who is still in the dark, is an advantage that he can take advantage of.

He bent down and gave Illya a smile as gentle as possible: "Illya, just follow your mother obediently, okay?"

Illya nodded timidly, her small hands tightly grasping Irisviel's fingers.

Irisviel gently held Illya in her arms, a hint of determination flashing in her ruby ​​eyes.

Sera led the way, and the three followed her, leaving Illya's room.

As he passed the door, Kiritsugu glanced around inconspicuously to confirm that there were no obvious ambushes.

In the corridor, the ancient tapestries cast shadows in the dim light, and the air was filled with the smell of fir and mold, which made people feel a little depressed.

Irisviel hugged Illya tightly, feeling the warmth coming from her daughter, trying to dispel the uneasiness in her heart.

At the end of the corridor, the door leading to the library was blocked by a giant black dragon.

The dragon's body was huge and majestic, and its scales gleamed with a cold light in the dim light.

Its eyes were like two burning coals, staring at Emiya Kiritsugu, Maiya, and Irisviel curiously and dangerously.

Sticky saliva dripped from the corners of the dragon's mouth, making a slight sound when it fell to the ground, as if reminding them of the danger of this giant beast.

Emiya Kiritsugu's heartbeat quickened, and his hand unconsciously tightened around the gun at his waist.

He knew that any firearms or other hot weapons would pale in comparison to this giant dragon.

Emiya Kiritsugu's eyes quickly scanned the surroundings, trying to find any possible escape routes or hidden ambush.

Irisviel hugged Illya tightly, feeling the warmth coming from her daughter, trying to dispel the fear in her heart.

There was a glimmer of determination in her ruby ​​eyes, and despite her insecurity, she knew she had to protect Illya.

The three of them didn't know what to do in front of the dragon.

Emiya Kiritsugu took a deep breath, trying to calm down and think of a countermeasure.

He knew that acting rashly would only put himself and others in greater danger.

Irisviel patted Illya's back gently and whispered soothing words to her, trying to reassure her not to be afraid.

There was a hint of curiosity in the dragon's eyes, as if waiting for their reaction.

Its tail swayed gently and it let out a low growl, as if warning them not to act rashly.

"Come in, Norbert doesn't bite."

"Nobel, move aside and let them in."

Chen Yu's voice came from behind the door.

Hearing Chen Yu's order, Norbert's huge body moved two steps to the side.

Irisviel and Emiya Kiritsugu finally felt relieved.

The three of them quickly walked through the heavy oak door, and a strong smell of books hit them in the face.

The Einzbern library was dimly lit, with towering bookshelves extending all the way to the dome, filled with all kinds of ancient books and scrolls.

This place records the Einzbern family's magical achievements over more than a thousand years. It is called a library, but in fact it is similar to a library.

Irisviel and Emiya Kiritsugu's eyes were not attracted by these things, but were instantly locked on the two people in the center of the room.

There, a black-haired young man was sitting leisurely on a quaint chair, flipping through a thick ancient book at a rapid pace.

What didn't fit in here was his attire.

Dressed in a silver-white steel battle suit, he looks like a future man who has traveled from a distant technological era to modern society.

Standing behind him was the patriarch of the Einzbern family, old man Eubusta Kuhaid.

The old man had lost his usual majesty and now stood respectfully behind the man, slightly bowing, like a loyal servant.

"Chen Yu...you, exactly..."

Irisviel uttered the boy's name in disbelief, her tone full of doubt.

But in just over ten minutes, the stubborn and obstinate old man, Yubusta Kuhayid, stood behind him like a loyal servant.

This scene caused a storm in Irisviel's heart.

The androids knew too well the extent of Yubusta Kuhaid's paranoia, which was simply beyond her understanding.

Kiritsugu fixed his sharp eyes on Chen Yu, and alarm bells rang deep in his heart.

Chen Yu raised his eyes from the heavy ancient magic book and handed the book to Yubusta Kuhaid who was waiting beside him, with a faint smile on his face:

"Don't be so nervous, Emiya Kiritsugu, Irisviel, and the lovely Illya."

His tone was gentle, yet it carried unquestionable authority.

"Do you know Illya?"

Illya huddled in Irisviel's arms and looked at Chen Yu cautiously.

"Of course, who doesn't know the lovely Illya?"

Looking at Illya's somewhat nervous face, Chen Yu smiled kindly.

"Sera, Lijelite, please go down first. There is nothing for you to do here for now."

Sera and Lijelite bowed respectfully and quietly left the library. The heavy oak door slowly closed behind them, isolating them from the outside noise.

Chen Yu briefly recounted the battle with the Einzbern family's androids.

His nonchalant tone shocked Irisviel and Emiya Kiritsugu greatly.

Their eyes involuntarily fell on Chen Yu's silver-white steel armor and the majestic dragon Norbert outside the door.

With such a powerful force, it is no wonder that Yubusta Kuhaid chose to surrender.

The doubts and vigilance that were surging in Emiya Kiritsugu's heart gradually subsided in the face of absolute strength.

The light in the library was dim, and the air was filled with the unique scent of ancient books and parchment scrolls, which made people feel a little dull.

"By the way, Irisviel," Chen Yu's eyes moved away from the ancient book in his hand and fell on Irisviel, his tone casual but with an unquestionable meaning, "Are you interested in becoming the head of the Einzbern family?"

This sudden question stunned Alice. She subconsciously looked at Yubusta Kuhaid, but found that the old man was just standing quietly behind Chen Yu without any expression.

She opened her mouth, but didn't know how to answer.

Before Irisviel could say anything, Chen Yu continued, "Although Eubusta Kuhaid led the Einzbern family to submit to me, what I am interested in in Einzbern is these collections of magic books and android technology. I am not interested in managing and leading the entire Einzbern family."

He paused, tapping his fingers lightly on the ancient book in his hand, making a dull sound, and his eyes swept across the towering bookshelves around him, as if evaluating the value of this knowledge.

Chen Yu then turned his gaze to Yubusta Kuhaid, with an imperceptible curve at the corner of his mouth.

He was not worried that the other party would become angry because of what he said.

He knew that in the face of absolute strength, so-called dignity and face seemed pale and powerless.

In other words, it would be strange if old man Yubusta Kuhaid had no ulterior motives. Chen Yu knew this very well, but was too lazy to point it out.

"After all, I'm going to be away for ten years,"

Chen Yu handed the magic book in his hand to Ubusta Kuhaid who was waiting beside him, "I don't have the energy to manage the Einzbern family."

"ten years?"

Irisviel finally found her voice and repeated the number with a tone full of surprise and confusion.

Ten years is a long time for humans, but for a magician who is looking for the root, it is just a blink of an eye.

"Yes." Chen Yu stood up, his silver-white battle suit reflecting a cold light in the dim light. "Just think of me as going somewhere else to gain experience. I will come back again in ten years and take Avalon away."

His eyes fell on Irisviel, with a hint of inquiry, "Maybe I'll take a few androids with me to work in my 'Dust Song Pot'."

His tone was flat, as if he was talking about a trivial matter.

"Of course, to prevent any accidents, I will have old man Eubusta Kuhaid and you sign a self-compulsory certificate. That should be no problem, right?"

Chen Yu's gaze shifted from Aliceviel to Yubusta Kuhaid.

That look was not a question, but more like a statement of an established fact that could not be questioned.

"Yes……"

Old man Yubusta Kuhaid lowered his head and agreed to Chen Yu's arrangement.
