Shirou quickly got the treasure tool that was officially finished in the blacksmith's workshop - Faraway Utopia Avalon (Avalon).
It's a golden mold almost exactly like the original, the sword sheath of King Arthur Artoria's Excalibur.
It is said to originate from the fairy realm where King Arthur rests, allowing the user to heal from any injury, even stopping the progress of aging. Also, by releasing its true name, the strongest protective barrier will unfold. Even magic from the Type-Moon world cannot interfere with the blessing of this treasure tool, and its existence itself is equivalent to magic.
In legend, the loss of this sheath brought misfortune to King Arthur's life, eventually leading to the collapse of the entire Britannia kingdom.
Until the Fourth Holy Grail War, Einzbern dug it out of the ruins and used it as a holy relic for Emiya Kiritsugu to participate in the Holy Grail War, and summoned the strongest Saber class Servant, King Arthur Artoria.
Later, Emiya Kiritsugu discovered the truth of the Holy Grail in the Holy Grail War, causing the Fuyuki fire. To ensure the safety of Emiya Shirou, who was rescued from the fire, he buried the sword sheath Avalon into Shirou's body, causing Shirou's body to be affected by the sword sheath for many years, and even his origin became a sword.
Later, this sword sheath also became the key for Emiya Shirou in the Fifth Holy Grail War, saving his life from crisis several times.
Of course, all of the above is the story of another Emiya Shirou, not the story of Shirou as Miyu's brother, but because he merged with Servant Emiya's soul, and Nanahoshi told him about it before, he basically understood everything.
Shirou now deeply understands the significance of the treasure tool Faraway Utopia to him, so once he has the opportunity, he will do everything possible to complete it.
With the help of Nanahoshi and the cooperation of the entire magic university's magicians, Faraway Utopia is now officially completed.
Although Nanahoshi made the design based on her own memory, this version is even closer to the original appearance than the initial version Shirou made in the Boreas family.
This shows how much effort Nanahoshi herself put into this matter.
After getting the sword sheath, a cool feeling suddenly came. It was the cool feeling emitted from the special material of the sword sheath itself. At the same time, the magic circle on the sword sheath was also operating spontaneously, invisibly healing the wounds of the person holding the sword sheath, and also stabilizing and recovering the holder's magic power.
Yes, the Faraway Utopia designed by Nanahoshi is indeed different from the original.
But this difference does not mean that some aspects are inferior to the original treasure tool.
On the contrary, the Faraway Utopia designed by Nanahoshi surpasses the original in all aspects.
First of all, the original Faraway Utopia (Avalon) could not show its power unless it was connected to Saber Artoria.
The treasure tool can only be activated when the sword sheath and the sword sheath's owner are together.
This overly exaggerated restriction meant that the sword sheath was almost completely useless when Saber Artoria was not a Servant, and was no different from scrap metal.
The Faraway Utopia designed by Nanahoshi naturally could not have such a huge restriction. Although restrictions still exist, she changed the restriction from establishing a connection with Saber Artoria to the sword sheath only being effective when it is bound to a Holy Sword, and even if the matching Holy Sword is not nearby, the sword sheath itself can still exert about half of its power.
The reason for this is that Nanahoshi's creation is based on her own magic circle theory.
A magic circle, simply put, is made by grinding magic power crystals into powder, mixing them with several fixed materials to make a paint, and then drawing it out. As long as it touches the paint, it will dissolve into the object and will not be easily eliminated. Once magic power is poured into the paint, it can amplify the power and exert the effect according to the shape of the magic circle.
But such a magic circle has a huge flaw, that is, the paint will evaporate after the magic circle is used once.
Also, depending on the magic, the materials used for the paint will also be determined.
Basically, when using large-scale magic above the king level, it seems that special paint is needed, and the actual preparation will require a huge amount equivalent to a national budget.
But Nanahoshi's creative talent allows her to make magic circles that can be reused and are no longer restricted by materials. As long as magic power is poured into them, they can be used. Moreover, she has also minimized the difficulty of using magic circles, so that people who lack magical talent can easily use magic circles and will not be limited by the difficulty of drawing magic circles.
Based on the above principles, Nanahoshi created such a Faraway Utopia that is extremely easy to use and can be used by anyone.
Binding it to the Holy Sword is more of a deliberate safety mechanism to prevent the sword sheath from being abused after falling into the hands of evil people.
After simply experiencing it himself, Shirou was very impressed with Nanahoshi's clever creation.
If he were to make it himself, it would be absolutely impossible to restore Faraway Utopia to this extent, and it could even be said to surpass the original.
Of course, this treasure tool still has problems, and whether it can surpass the original is questionable.
That is its strength as a defensive barrier.
The original Faraway Utopia's defensive ability can be said to be exaggeratedly high. Even Gilgamesh's Ea sword cannot destroy it, and can even bounce off attacks.
It is really doubtful whether the version created by Nanahoshi can reach that level of defense.
To prove this, Shirou specifically asked Rudeus to test it for him.
He himself opened Faraway Utopia to defend, and then asked Rudeus to release holy-level magic to bombard it.
The result was that the barrier was unharmed and could not be destroyed by holy-level magic at all.
He then increased the difficulty and asked Principal Jinas to release king-level magic to attack. As a result, the barrier was slightly affected, and the magic power consumed increased, but it was still able to withstand the damage.
Shirou judged from this that this version of Faraway Utopia should be able to withstand emperor-level magic, as for god-level magic above that, unless someone can help him test it, it is likely that he will not be able to test a specific result.
In addition to this, Shirou also tested the recovery ability of Faraway Utopia.
He resolutely put himself in a seriously injured state and integrated Faraway Utopia into his body to see how the recovery ability was.
The result was that it had a recovery magic almost equivalent to the king level. In just a few minutes, the seriously injured areas recovered to be no different from the original.
With these test data, Shirou could almost be sure that this version of Faraway Utopia had enough practical value, and it might even be useful against opponents of the level of the Dragon God.
So he gave all the money he had earned as an adventurer to Nanahoshi and the many magicians who helped him as a reward.
Among them, Nanahoshi took the money and left without any emotion. She also needed to spend money on her own research, so she would not avoid any opportunities to make money.
The magicians who assisted Shirou had different attitudes.
Principal Jinas and Fitz and other magicians wanted to refuse, but under Shirou's coercion, they still took the money.
Rudeus refused to take the money, so Shirou didn't give it to him. After all, they were family, so there was no need to be too picky about money.
Although Juliet didn't want to take the money either, Shirou still gave her some pocket money as wages.
After all, Shirou couldn't bear to freeload because of the little girl's age.
As for guys like Linia and Pursena, because they were not useful in the process and their personalities were annoying, Shirou had no intention of giving them money at all. He directly became a capitalist and sent them away without paying a penny.
After Shirou's forging was completed, what he needed to do was to conduct research for Nanahoshi.
Nanahoshi's goal is to research summoning magic. She wants to find magic that can summon humans from another world, because as long as she can find a way to summon other people over, she can reverse engineer a way to return to her original world.
But this is undoubtedly an extremely difficult thing. Nanahoshi has spent several years, but still has not made any obvious gains.
Nanahoshi herself has obviously adapted to this situation, so she is not discouraged by her failure at all, and is still creating magic circles according to stable steps.
Shirou's task is to inject magic power into the magic circles designed by Nanahoshi each time.
At first, Shirou thought this would be a very easy task, but after a few times, he realized the difficulty of this task.
Simply put, the amount of magic power required by the magic circles made by Nanahoshi is too high.
Although Shirou doesn't think his total magic power is low, he still almost can't fully meet Nanahoshi's requirements.
For this reason, he originally wanted to recommend his younger brother Rudeus to Nanahoshi. He felt that with Rudeus's total magic power, he might be able to meet Nanahoshi's conditions.
But Nanahoshi herself seemed to have little interest in cooperating with people other than herself.
She told Shirou that it didn't matter if the progress was a little slow, she could wait patiently.
Seeing that Nanahoshi was so repulsed by social interaction with other people in this world, Shirou could neither reveal that Rudeus was suspected of being a Reincarnated Person, nor could he force her, so he could only give up.
…
Days passed by like this.
Shirou travels between the magic university's library and the blacksmith's workshop every day, studying and improving his magic power, and researching magic for Nanahoshi.
Shirou's magic skills have not changed dramatically, and he has not thought of a way to defeat Servant Emiya and regain control of Unlimited Blade Works.
Nanahoshi's research on summoning magic has also made little progress.
Everything seems to have come to a standstill.
Shirou even occasionally has the idea of leaving the magic university to find Paul and search for Zenith's whereabouts with him.
But this idea only lasted for a moment.
The world is so big, if the investigation team organized by Paul can't find anyone, it doesn't make much sense to have one more person. It's better to study magic more, maybe he can find a way to control his clairvoyance, so that he can directly determine Zenith's location.
So Shirou is no longer anxious.
Basically, he is still mainly thinking about his own affairs now, and occasionally helps out at Ariel's student council.
After all, Shirou knows Ariel's current situation very well. Although he can't directly support her in ascending the throne because of his family's disappearance, he is willing to provide some support and do what he can.
He heard that Ariel seems to want to gain the support of some high-ranking nobles in the Ranoa Kingdom recently.
For this reason, she specifically asked Shirou, hoping to borrow Shirou's reputation.
Although Shirou himself doesn't think he has any reputation, he still agreed. As a result, when Ariel said Shirou's name, the other party immediately treated her warmly.
This made Shirou very confused, wondering why his name had such a big influence on the high-ranking officials of this country.
In fact, Shirou now has a very high reputation in the three magic kingdoms.
Not only because he himself is an S-class adventurer, but also because he has gained the approval of the principal of the magic university, and even defeated the demon king alone and won over the amazing Silent...
All of the above have given him a huge influence in the three magic kingdoms where strength is respected, and the nobles of the three magic kingdoms respect him very much.
So Ariel can get support immediately just by saying Shirou's name.
Although Shirou doesn't realize this, he is also very happy that he can help Ariel.
If Ariel can ascend the throne of Asura in the future, it will not only be helping Ariel, but also helping Eris and solving the problem of the Boreas family.
Shirou is naturally happy to see all this happen.
In addition to this, Shirou also received a letter from Paul.
After Shirou found Rudeus before, he wrote a letter of peace to him.
Now this is considered to be a reply.
Paul's letter said that Paul has obtained information through the investigation team during this period, and it is said that the other party has narrowed down the area of Zenith's location to the Begaritt continent. If there is further clues, he will send someone to notify him.
Paul also said that because the Begaritt continent is too dangerous, he chose to send Aisha and Norn to Shirou and Rudeus's side, hoping that they can take care of the two younger sisters.
Shirou will naturally comply with Paul's request.
He has even begun to think about where to let his younger sisters live when they arrive.
He can't let the two younger sisters live with him in the blacksmith's workshop.
After thinking about it, he ran to Rudeus to discuss it and decided to buy a house near the magic university and rebuild a Greyrat house.
Rudeus was naturally very happy about this and immediately decided to do it.
Fitz seemed to be very concerned after hearing about this, and even asked Ariel for leave to help with the house purchase.
Everything is developing extremely smoothly, even a little too smoothly.
Just when Shirou thought that the days would continue to develop like this day by day, the problem came inadvertently and suddenly.
One day, Ariel called him to the student council room and deliberately had a private conversation.
As soon as they met, the second princess of the Asura Kingdom opened her mouth with a serious expression: "Shirou, I want to ask you a question. Are you really the blacksmith Muramasa?"
