The establishment of the Time Travelers Alliance began in the first year of Conan

Chapter 344 Where did the historical inertia of the Fourth World War come from? (Seeking monthly votes)
Hisayu Maiya successfully completed her mission.

Whether it's delaying Lancer, or concealing things from Saber, Irisviel, or even from herself.

Although her actions were genuine and her reasons sounded reasonable.

However, there are some key matters that the alliance has concealed from them.

After all, it seems that the only person the Alliance can trust outside the base right now is Matou Kariya.

The existence of the "soul" issue, along with the unusual behavior of Hisayu Maiya at the Hyatt Hotel not long ago, has determined that she can only be an unofficial staff member for now.

“Spiritual intelligence, historical intelligence… every crucial aspect of this universe is related to the concept of ‘intelligence’.”

Conan wasn't worried at all about the magicians who stayed at the observatory base or occasionally went out on field missions.

Putting aside the fact that as "special task force members," their actions usually only require following pre-arranged plans—their authority is not sufficient to leak any important information.

Furthermore, considering that it doesn't even have a "persona," it's hard to believe that the enemy would try to gain anything from it.

As for researchers like Meastia who are knowledgeable about things like "historical inertia".

Compared to their past selves, they have transformed from "model airplanes" into "rockets".

Just as the gods had to relocate to the "Sea Within the Stars" after the decline of the Age of Gods.

They are no longer "adapted" to the external environment.

Unless the enemy can replenish their CYZ effect and easily provide a dozen or so ley lines for energy.

Having already obtained the [attribute panel], they have eliminated the possibility of leakage at its source.

But Hisayu Maiya is different.

The "covering" of its "soul" that happened not long ago obviously had the most subjective and direct impact.

"Even with the technology to cover it, extracting relevant information will not be difficult."

Considering Hisayu Maiya's role in the Fourth Shinobi World War, the League obviously cannot directly "convert her into a Heroic Spirit" right now.

Therefore, in addition to guiding the "historical inertia" in the right direction, this mission also aims to mislead the enemy by taking advantage of Hisayu Maiya's perception.

"If I'm not mistaken, the information she learned in front of the Hyatt Hotel will probably be exposed soon."

Facing Hasegawa Tsuki, Conan's tone made it sound like such an information leak was just a minor matter.

"Commander Kudo, did you do this on purpose?!"

"How could that be? I could never have predicted that the enemy would target Hisayu Maiya."

Conan said that Hasegawa Tsuki really thought too highly of him.

"It's just a case of playing along."

He paused for a moment, then explained his considerations.

"I did consider revising her memories again, or at least blurring them a bit. But that would just make it seem like I was trying too hard to cover it up."

“Moon, you should always be aware that the intelligence on both sides is very vague right now. In other words, such unintentional leaks are actually beneficial to the alliance.”

Conan doesn't believe Merlin's appearance is just a coincidence.

"If he deliberately came to us because of a leak of information, then everything makes sense."

A playful smile appeared on the detective's face.

"Moon, think about it, what is the most obvious difference between the core of this [universe] and [this universe]?"

Hasegawa Tsuki recalled Conan's recent mention of Merlin and the idea that "leaking information isn't necessarily a bad thing."

She hesitated for a moment, then responded in an uncertain tone.

"Hmm... Does the alliance have any allies we could try to win over?"

Conan nodded approvingly.

It seems that during this period, he secretly stuffed those theoretical books from the Narrative Studies Department into the database.

It was worth seeing the moon over Hasegawa.

"Yes, epic tales of heroes, epic tales of heroes, although I do not like some of them."

"But in any case, the side of 'justice' will always have a favorable impression of those who share the same ideals, and may even offer them help."

Looking at the critical expression on Conan's face, Hasegawa Tsuki really wanted to retort—

His superior seemed to have said something similar to what he had said.

Didn't he also help Matou Kariya and Matou Sakura?
Hasegawa Tsuki silently remarked to herself that Commander Kudo was all talk and no action.

Then, she keenly realized the potential implications of this inference.

"Are you saying that Merlin might be here to help us?"

"There's no mistake. His mere presence has provided a wealth of information, not to mention the hints he gave to Artoria."

"Although we don't know exactly how much he knows, it's clear that he's on our side right now."

It can only be said that wise people always cherish each other.

In Conan's eyes, Merlin's words were practically a direct message of "Save Saber" onto his face.

"but--"

Conan's words suddenly changed mid-sentence, causing Hasegawa Tsuki's heart to leap into her throat once more.

"His premise for doing this was that the alliance came from another universe, and that it was a benevolent force that was preparing to leave this universe."

This is also why Conan decided to give Hisayu Maiya some false information, or more accurately, to mislead the forces that could detect her abnormality, since leaks could not be completely prevented.

"It's like someone might kindly offer a room to a weary traveler for the night."

Conan used a metaphor that was easy to understand.

"But that doesn't mean he'll just carve out a room in the house and give it to you."

"Moreover, just as the weak usually only ask the strong for help, you would never try to ask an ant for help when you can't lift something."

In Conan's view, the most important thing for the league now is to have a "tiger skin".

Imagine if one day, a spaceship suddenly landed right above Earth.

Any rational person would definitely consider the technology, logistics, possible homeworld, and more spaceships needed to achieve this.

Instead of thinking that there was only one spaceship, or even that the warp drive on it was just something they found by luck.

"Given that the alliance is now acting as a 'traveler,' Merlin obviously doesn't need to worry too much."

Conan reveals the fundamental reason why he believes this misleading narrative should continue indefinitely.

"No matter what, Merlin is definitely on the side of the [Universe]."

After all, Conan finds it hard to imagine that someone would directly turn against an "outsider" who didn't create him.

Umebayashi is not Matou Kariya.

According to the database, this nightmare did not encounter any setbacks or suffer from any unresolved pain.

—In the context of historical inertia, his fate and ending were not bad.

"Therefore, if he knew we were coming to occupy a piece of land, and knew that we currently only have less than 11-string CYZ effects, he couldn't do much to interfere..."

"They may not be hostile to us immediately, but they certainly won't be friendly either."

"The most crucial information that the alliance has revealed so far is that the inertia of history is hard to defy, and that some figures have established personas."

The leak of this information cannot be said to be harmless; its meaning is simply incomprehensible.

If you are not a member of the Alliance, you may not be familiar with terms such as "worldview system" and "shell".

From a literal perspective—

[Historical Inertia] Ah! I get it! It's fate, isn't it!
[Character Setting], right? Yeah, so according to history, Joan of Arc would definitely have been burned at the stake, so she's supposed to be a village girl, right?!

So, do you see, was this information really leaked?
It can only be described as a leak.

Perhaps the only one I know more about is [Matou Kariya], because of TDD.

But he has the least to worry about regarding leaks.

It is important to know that Hisayu Maiya was "attacked".

At the moment when what was about to cover her almost restored the entire universe.

—Matou Kariya is completely unaffected.

Conan even suspects that even if Kariya were to remove TDD now, he could withstand this "reset" with just the Timeline Mask, without using the CYZ effect.

Of course, one thing must never be revealed: the significance of the RSI value. This is why Hisayu Maiya was told that it was Artoria's acknowledgment that reduced the pressure she faced—the surrounding RSI environmental value.

The result is true, but the reasoning behind it is wrong.

Before anyone actually steps forward to tell him that the theory about the "core" needs to be revised, Conan is very clear about one thing—

The increase or decrease of the environmental RSI value is usually only affected by the core itself, or by the offset due to historical inertia.

Just like Detective Conan, whose RSI is as high as 333, he is still at a disadvantage in some cases when facing criminals.

A high or low RSI value does not directly indicate whether a character is strong or not.

It's like if you were to go to Universe 1 of this universe now and play Jack the Ripper in "The Phantom of Baker Street," which is already at the end of the third cycle.

You can easily defeat Conan, and even corner him—but only without considering the consequences you're about to face.

Therefore, the changes in Matou Kariya, Hisau Maiya, and Emiya Kiritsugu may indeed be related to the fluctuations in their RSI values.

But this does not mean that "they themselves caused the increase in the numbers".

While a breakthrough in one's "persona" can indeed cause fluctuations.

But as I said before, considering that such a "breakthrough" is a violation of historical inertia, it is difficult to distinguish between them.

Just like in this universe, the only two beings truly recognized by the Alliance as "RSI anomalies" are Conan Edogawa and Akako Koizumi.

As for other things, they can only be called "RSI anomaly derivatives"—such as the Throne of Heroes, Alaya, and so on.

And so did Hisayu Maiya and the others.

Seeing what had just happened, Conan projected the scene where the RSI index decreased.

"In short, if violating the historical inertia will cause the RSI to rise and fluctuate, then following it will indeed cause it to calm down again."

"According to the [historical inertia], Lancer should never have appeared at this moment when Assassin was about to be killed. If he had gone there, he would likely have directly confronted Archer at this time."

"And that is why Hisayu Maiya's CYZ effect consumption and the corrections she receives will be smaller than in the past."

Of course, Conan wasn't actually happy at all.

This proves that his previous conclusion, based on Ilya, that "historical inertia" was "dispersed" is completely wrong.

its not right? !

Looking at the environmental RSI index of nearly 102 on Hisayu Mami's panel.

Conan jumped up from his seat, a look of surprise and uncertainty in his eyes.

He remembered it clearly.

The RSI environmental index of this universe that the Alliance initially measured should have been 101.000...013 (see Chapter 7 for details).

But now, in a short period of time, it has risen to nearly 102.

The environmental RSI value of the [universe] should theoretically only change due to changes in the [core], right?

As the [Timeline] trait flashes through the base.

Conan glanced at all the records of the increase in the environmental RSI index from the past to the present—

Although the previous data had slight fluctuations, it always quickly returned to its original value.

This time, the environmental RSI index did indeed increase after Lancer was stopped.

More importantly, there is no sign of this number dropping so far.

"Nothing changed when Illya was taken away, nothing changed when the historical inertia of Matou Kariya and others was changed, but after Lancer was stopped, there was an increase that did not fall back."

Without specific comparisons, it is difficult to determine the specific objects affected by the fluctuations in the RSI values ​​of [persona] and [historical inertia].

In my mind, the summaries and theories made by the Department of Narrative Studies suddenly echoed.

Conan muttered to himself.

If the alliance is the dominant factor driving the "Fourth Holy Grail War" due to historical inertia...

"Is there really such a thing as the historical inertia of World War IV?!"

At this moment, Conan finally discovered the reason why so many contradictions had arisen since he arrived in the Type-Moon universe.

If there is more than one historical inertia in a universe, then who decides the mechanism for determining this "shell"?

……

In fact, Conan's deduction is already exceptionally close to the truth.

Even, just like the "universe" where the Alliance currently resides, it only exhibits a Volatile level threat—

The historical inertia known as the "Fourth Holy Grail War" has undoubtedly reached the point where it is about to be "abandoned".

To give a more vivid example.

That was the [reality timeline] of [this universe], which incredibly overpowered the [story timeline] and successfully gained dominance.

Of course, considering the complexity of the historical inertia within the Type-Moon universe itself, this doesn't seem surprising.

But without a doubt, just like in the past [reality timeline of this universe], they knew how to use [alliances] to gain certain advantages.

At this very moment, the ongoing "Fourth Holy Grail War" has, for the first time ever, "entrusted" this hope to the [Alliance].

In a sense, perhaps only the real-world timeline before the emergence of the Alliance could be worse off.

Unlike the universe in which everything is a manifestation of "time".

This "historical inertia," symbolizing the "Fourth Holy Grail War," can be said to have nothing to do with anything.

In a sense, the reason it can still "exist" at this moment is actually because it relies on its own enemy and on the "pan-human history" that does not exist in this "historical inertia".

In fact, unlike the timeline itself, it does not have the "instinct" to continue.

At this moment, its ability to save itself is also dependent on the enemy's "inertia" in order to have the "awareness" of such action.

That gust of air that moved automatically without wind from inside Ryunosuke Uryu's warehouse, that gentle breeze that blew the magic book, and even the page with the "summoning circle" on it, right next to Ryunosuke.

In a sense, this is actually the first attempt by this "historical inertia" to regain some control.

Because, if we only rely on the character design of [Ryunosuke Uryu]...

Without knowing any information about the Alliance, after Fuyuki City became harmonious and stable.

Logically speaking, Ryunosuke doesn't have many more chances to summon Bluebeard.

Even the subsequent attack on [Matou Kariya] by [Chaldea], where that message appeared before Leonardo da Vinci, was undoubtedly its "masterpiece".

In fact, this also shows the strength and weakness of "historical inertia".

It can even rely on subtle rises to use various "reasonable" means to obstruct the "cutting of the world"—but it is difficult to make deeper interventions on those "destroyers" to some extent.

Even [Kuyu Maiya] can easily violate its "reset" under the extremely small amount of CYZ effect compared to that in [this universe].

But in any case, it is indeed a kind of historical inertia.

Furthermore, judging from Kiritsugu Emiya's RSI value, which clearly rises faster than others—

Having learned from its defeat in the Branch Wars, it is now trying to defy some of its own "inertia" and give Emiya Kiritsugu a core position.

However, if it weren't for the fact that [Kuyu Maiya] carried the [Grimoire], becoming an exceptionally accurate "detection device,"...

Because its "existence" is so insignificant now, even Conan wouldn't notice this subtle difference.

After all, Conan initially thought that the historical inertia of the "Four World Wars" was less than or even non-existent in terms of character settings!
Moreover, this near-disappearance of "existence" brings a certain degree of concealment.

It is precisely because of this——

At present, its chances of "winning" seem extremely slim.

……

As for Conan...

Verifying the validity of the conclusion that "the historical inertia of the Fourth Holy Grail War exists" is also very simple.

At this very moment, the alliance member responsible for providing support among the [Heavenly Executioner].

This guy, who had been lucky enough to escape with his life because Lancer was stopped, dragged a somewhat complicated device out of the van following the instructions of the puppet-shaped communicator in his ear.

To prevent errors...

Conan decided to examine it carefully and make a record of it—

The change in the environmental RSI value at the moment Assassin is "killed" by Gilgamesh.
