"Let's go to the castle and get some rest, Saber."
Shirou patted the girl lightly on the shoulder and said.
"Yes, I understand."
Although the battle just now didn't consume much magical energy, the girl, who was still mentally exhausted, nodded.
Although her body was not tired, her heart was a little weary.
It is better to be alone for a while at this time.
Shirou didn't disturb her thoughts but turned to look at Irisviel.
"Irisviel, there is something I would like to talk to you about alone."
Hearing Shirou's words, Hisau Maiya glanced at him with some wary eyes, but after thinking about it carefully, she felt that Shirou couldn't do anything to them.
Because now Saber's control is in the hands of this man. Not to mention that his strength has just been deeply recognized by Hisau Maiya in the duel with Archer, so if there is any attempt, it is impossible for them to resist in any posture.
"Good."
Irisviel didn't think as much as Maiya did, and knowing Shirou's true identity, she immediately agreed.
Then, suddenly, she spoke again.
"Shirou, you have consumed so much magical energy, do you need me to replenish you?"
"W-What!?"
At Irisviel's sudden words, even Shirou couldn't help but gasp.
Replenish? Tantric rituals?
As soon as he thought of this term, Shirou quickly shook his head.
Irisviel naturally couldn't have meant that, and what she said about replenishing magical energy was probably some other way.
Seeing Shirou's strange reaction, Irisviel was stunned for a moment, and then as a magus, she naturally thought of something and couldn't help laughing.
In her opinion, Shirou is still only a 7 or 8-year-old child, although he uses magecraft to make his body look the same as when he was a teenager.
What's more, Irisviel herself is just a homunculus, one of the homunculi refined based on the prototype of Justeaze Lizrich von Einzbern. If the other party really needs it, in fact, as long as he goes to the Einzberns, he can get a homunculus exactly like her.
Of course, this is only possible if the Einzberns feel that this magus can lead the future of the family.
Shirou naturally also discovered the meaning of Irisviel's smile and immediately sighed in his heart that he was born at the wrong time.
Then, he didn't think much about it but spoke directly.
"Irisviel, Saber's scabbard, Avalon, is inside you, right?"
"How do you know that————?!"
Hearing Shirou's words, Irisviel's pupils suddenly dilated, and her ruby eyes were full of disbelief.
She really didn't understand why Shirou knew about this; after all, such an important matter was basically only known to herself and Kiritsugu, and it was impossible for other magi to know.
Immediately after, she hurriedly looked back at Saber, who was helping Hisau Maiya back to the castle. After seeing that the other party was not aware of the situation here, she turned her face and asked Shirou.
"Avalon is indeed with me, but Shirou, where did you learn about it...?"
After a brief shock, Irisviel finally regained her composure and spoke with some trepidation.
"Truth be told, because I am the vessel of the Holy Grail, I receive a soul every time a Servant dies, and so far, three souls have been received. With my weak body, I can now move around as a normal person thanks to the healing power of Saber's scabbard. If I take out the scabbard, my current body will immediately become extremely weak..."
In other words, as long as the scabbard is removed, it will become difficult for Irisviel to even move.
Shirou smiled as expected and continued.
"Madam, when I made a contract with Saber before, I agreed to your request to take the Holy Grail for her."
"Well, that's right..."
Irisviel nodded.
"In that case, I will tell you the truth. With the combined strength of Saber and me, we may not be able to defeat Gilgamesh. If we want to defeat him, we must need Saber's scabbard, Avalon."
Hearing this, Irisviel's pupils suddenly shrank, and then even her breathing became a little short.
"Really... Can you really beat that Archer?"
In front of her eyes, the golden wall that obscured the sky seemed to emerge again, and the group of Noble Phantasms poking out from the thousands of ripples rippling in the golden wall.
Shirou nodded affirmatively.
"Of course."
Hearing this affirmative answer, Irisviel finally stopped hesitating and said to Shirou.
"That... All right."
In fact, the last thing Shirou wanted to think about was how to insert such a large scabbard.
However, when he saw Irisviel pursing her lips and taking out the blue and gold scabbard with a slightly painful expression, Shirou's pupils also reflected the light at this moment.
"This is... Avalon!"
The Ever-Distant Utopia in the legend of King Arthur. The scabbard named after the fairy land is also the hometown of the fae in Western myths and legends.
"Avalon," also known as the "Ever-Distant Utopia," not only has the power to heal the bearer's wounds and halt aging, but it even breaks down into hundreds of pieces after the release of the True Name, protecting the owner from any interference.
Of course, Avalon is powerful, but it also needs Saber by its side to be effective.
In a way, Saber is the power bank of Avalon.
"Now, I will give you Avalon, Shirou."
The moment she took out the scabbard, Irisviel's body immediately became shaky, as if she was about to fall to the ground in the next moment.
The light turned into a silhouette, an object that shone with a metallic texture, blue lines, and golden light.
Shirou hurriedly took it, and the moment he touched it, the scabbard turned into a ray of light and disappeared into Shirou's arm.
"I... I am so tired..."
Seeing Irisviel, who almost fell, Shirou hurriedly stepped forward to help her.
Irisviel didn't seem to be able to open her eyelids very much; her body was limp and she had no strength at all.
"How are you, Irisviel?"
"I... I am fine, I just need a break..."
Irisviel, who was in a weakened state, didn't even think about the fact that she was lying in a man's arms, only that she could have a place to sleep.
"I will help you back."
Shirou picked up the silver-haired woman horizontally and walked toward the castle.
