A journey into an infinite dimension

"So we, Chaldea, sincerely invite you to join us and fight to save humanity."

Olga Marie bowed her head deeply to Jiaye and invited him sincerely.

"Thank you for your information, Director Animusphia. Please give me some time to think about it."

After looking at Olga Marie deeply, Jiaye's tone and expression did not change at all because of Olga Marie's words.

"What else do you need to consider? Humanity is in imminent danger! Spirit infiltration requires time to practice, and a plan to save humanity also requires time to formulate. We don't have much time left for you to consider————"

Olga Marie stood up suddenly, and before she could finish her excited words, a strand of silver thread that was invisible to the naked eye quietly wrapped around her body, just like a puppet without freedom in the hands of a puppeteer. In her horrified eyes, her body involuntarily took a posture with her hands pinching her neck.

"No, you can't yell at my Jiaye or anything like that."

Hong walked out from behind Olga Marie, gently reached out and cupped her cheeks, with a charming curve at the corner of her mouth.

"If you do this, I will want to kill you."

"Okay, Red, don't be rude to the guests. Director Animusphia was just a little excited for a moment. She means no harm."

Sighing, Jiaye walked behind Hong, gently lifted her collar and put her on the sofa, then spoke apologetically to Olga Marie who had a face full of shame.

"I'm sorry, Hong was just worried about my safety."

Hong hooked her finger at Olga Marie with a bored look on her face, and she immediately felt the restraints on her body disappear, and at the same time she regained control of her body.

"...How long do you need to think about this?"

Olga Marie looked at Hong who was playing with her hair with lingering fear and apprehension. She did not bring up the situation just now, but just asked with a complicated expression.

"Three days."

"Okay, I'll come visit again in three days. I'll take my leave now."

--------

"..."

After hearing Jiaye's answer, Ling was silent for a while, then looked at him half seriously and asked.

"Jia Ye, are you really willing to entrust our future to a group of strangers?"

"..."

Just as he was about to pick up the book, he paused, turned his back to Ling, and a bitter smile appeared on Jiaye's lips.

"Of course I'm worried. Putting your hopes on others is the most foolish thing to do."

Jia Ye took out "Faust" by Johann Wolfgang von Goethe from the bookshelf, but did not open it. Instead, he swapped its position with "Alice in Wonderland" and put it back on the bookshelf next to "The Hunchback of Notre Dame".

"But I just got home, so let me rest for a while."

"Even though he said that, Jiaye just doesn't want to leave the ugly duckling alone at home anymore."

Hong sneered and directly revealed Jia Ye's true thoughts.

"Long-winded."

With a twitch of his mouth, Jia Ye walked over, picked up the pastry on the table and stuffed it directly into Hong's mouth, blocking her mouth.

"Gaya is really too much. He actually stuffed such a big thing into my mouth with such force."

Chewing the pastry and swallowing it, Hong licked her lips seductively and teased.

"Gaya, go ahead, don't worry about me."

Ling and Jiaye tacitly ignored Hong. Ling looked at Jiaye for a long time and suddenly smiled softly.

"I've already waited five years, so I don't mind waiting for an indefinite period of time. Besides, I trust you more than anyone else, so I will wait for you to come back."

As inorganic mechanical sounds rang out continuously, the pure white ceiling covered by a layer of transparent glass in front of me was quietly replaced by a vast expanse of blue sea. Seagulls were circling in the sky, and fish could be seen jumping on the water from time to time.

The sky and the sea seem to be connected as one, with only a faint horizon separating the two at the very end.

Standing on the beach, stepping on the fine and warm sand, Jia Ye raised his hand and moved his wrist. He bent his five fingers and gently clenched his fist, then released it. After repeating this several times, he turned around and looked at Hong who was standing behind him.

"Do you feel unwell?"

Jiaye asked with concern.

“It’s not much different from when we were outside.”

Hong shook her head and raised her eyes to look at Jiaye's closed eyes.

"As expected, even in this imaginary world you still can't control your eyes?"

"After all, the object of the spirit particle transfer is not consciousness, so this is normal."

With a slight smile, Jia Ye was not too disappointed. After all, he had never had any expectations from the beginning that he could 'open his eyes in the virtual world', so in return, he naturally would not feel disappointed at all.

"It's okay. I'm used to it anyway. If I could open my eyes suddenly, I would feel uncomfortable."

[———Heroic Spirit Summoning System: Destiny, Activate———]

At this moment, a mechanical prompt sound suddenly sounded, interrupting the conversation between the two and making them turn their heads to look at an empty space on the side.

A gorgeous and complex light golden magic circle quietly bloomed and rotated on the beach before the two people's gaze, releasing enormous magical power.

A figure gradually emerged from the magic circle, and at the same time, the suggestion voice that had been heard earlier came again from an unknown direction.

【——Servant Summoning: Completed——】

[———Contract Servant: Assassin———]

【——Battle time: 30 minutes——】

[———Simulated Battle: Begin———]

A dark figure shrouded in black fog was half-kneeling and facing the two of them. Only the outline in the fog could tell that it was a human-like being.

As the prompt says, this is the sublimated existence of a hero whose great achievements in life have been passed down as legends after his death and who has become an object of faith. It is a "Heroic Spirit" - or rather, the shadow of a Heroic Spirit.

Heroic Spirits exist in the "seat" outside of this world and are beings beyond humanity. Their form of existence is already within the realm of "magic" and cannot be understood or transcended through magic.

To save humanity, human power alone is not enough, because human power alone is not enough to cause a devastating crisis for humanity. Similarly, facing an existence of this level, unless it is those elusive magicians, even the highest-level magicians among humans - 'Grand' are only qualified to serve as cannon fodder.

Only those heroes who have left a clear mark on humanity can Chaldea rely on to save humanity.

And people like Jiaye, who are suited to their nature and selected from among humans, only play the role of servants and commanders.

The Heroic Spirit Summoning System—"Destiny"—is the reason why the task of saving humanity is entrusted to Chaldea, rather than other mage organizations.

Through this system, humans can sign contracts with Heroic Spirits and gain the right to command them. Such people are called "Masters."

Those who are demoted from Heroic Spirits and transformed into familiars used by Masters are called Servants.

However, although Chaldea has a system for summoning Heroic Spirits, as a historical legend on the "throne", it is not so easy to summon Heroic Spirits as familiars and servants and command them.

According to the records of Chaldea, there have only been three successful instances of servants being summoned using the Heroic Spirit Summoning System. Those three successfully summoned servants are said to be currently living in Chaldea, but no one knows where they are active, and no one has ever seen them.

Therefore, what stood before the two of them at this moment was, at best, the "shadow" of one of the Heroic Spirits atop the "Throne," a degraded, mindless wreckage or clone, possessing only a tiny fraction of their power.

As for the so-called 'Assassin'——

Heroic Spirits are beings separated from the timeline and are summoned to all eras, whether in the past or the future.

In addition to their powerful strength, Heroic Spirits can serve as warriors to restore humanity and are regarded as an important means of combat by Chaldea.

However, summoning the true form of the Heroic Spirit recorded on the "Throne" is an extremely difficult task, and there is almost no possibility of it being accomplished by human means.

Therefore, humans can only summon Servants who are their clones.

The power of the Heroic Spirit summoned in this way will be fixed in one direction.

For example, a Heroic Spirit who could wield both a sword and a spear at full power during his lifetime, when he manifests as a Servant, will only be able to use one of the two, and only that one.

This power determines the Servant's direction, i.e., class.

Therefore, when a Heroic Spirit appears in the world, it will first obtain the "Spirit Core" which is its heart. Then, with the "Spirit Core" as the center, the Servant will form a body constructed by magic power, and through this, it will obtain a container called a "rank" and thus materialize.

This class and container is what is called the "Spiritual Base".

It determines how much power a Servant will have in life, and at which class they can manifest.

In view of this, the larger and broader the spiritual base, the stronger the power of the servant.

Generally speaking, servants are divided into seven classes:

————"Saber (Swordsman)"

————"Archer"

————"Lancer"

————"Rider"

————"Caster (Magician)"

————"Assassin"

————"Berserker"

The Assassin who was in front of Jiaye and Hong at this moment was a class that was good at hiding its presence and lurking close to the target, then waving its sleeves and leaving without a trace after killing the target with one blow.

"Assassin? This is a good opportunity to test the effectiveness of the Kisaragi family's secret techniques on a Servant."

Looking at the Assassin in front of him, as if thinking of something interesting, Jiaye's mouth corners quietly raised a hint of evil smile.

"Ah, is Jiaye thinking about something interesting again?"

Seeing the smile on Jiaye's face, Hong couldn't help but cover her mouth and smile.

A closer look revealed that her delicate face also had a curve similar to Jiaye's. At this moment, it was as if a mirror existed between the two of them, and it was unclear who was the person in the mirror. However, this double malice still made the people of Chaldea, who were observing everything outside the virtual world, feel a chill.

"Captain, this 'Grandmaster' seems to be in some danger."

He seemed to be a weak character, but there was a softness between his eyebrows. The orange-haired man in a white coat seemed a little surprised and said to Olga Marie who was standing next to him.

"..."

Olga Marie did not reply, but just stared at the several projection screens in front of her in silence.

There is a different picture on each screen, there are nine of them in total, including the imaginary space where Jia Ye and Hong are located.

"After all, she's the youngest 'Champion' in the world. If you're too naive, you won't be able to reach that position as a minor."

Just when Romani Aqiman was feeling a little embarrassed because he was ignored, an intellectual man in a green coat took over his conversation, making him give the man a look that said 'I'm saved'.

"After all, even our proud director suffered a setback at the hands of this gentleman."

Smiling at Roman, Leif Lenore turned his head and said teasingly to Olga Marie.

"Leff, you've talked too much."

Olga Marie glanced at Leif lightly, but she was not angry. She just continued to stare at the picture on the screen where nine adaptable people were leading their respective shadow servants to be active in the virtual world, but her eyes were more focused on the picture of Jia Ye.

"Speaking of which, how well does his automaton adapt to spirit particle transfer?"

"It's absolutely perfect, like a puppet made for this purpose."

Leif shook his head. When he mentioned this matter, a look of surprise and curiosity appeared on his face, which had always been smiling.

"Can I only say that it is worthy of being the crystallization of the magician's highest technology?"

"I advise you not to take advantage of that puppet."

Olga Marie turned to Leif and gave him a serious warning.

"Everyone in the Clock Tower knows that the doll is Kisaragi's bottom line. There have been those who coveted her in the past, but they all died in the most desperate ways before they could make a move, whether they were noble magicians or lecturers and directors of the Clock Tower."
