Chapter 398 The Method to Return to [This Universe]
(This chapter contains many settings; you can skip it if you don't care.)
"Sakura, the academy needs me to go there."

Standing in the entrance hall, Yan Ye picked up his long sword, his expression somewhat sorrowful.

Is it that I don't want to understand, or that I'm unable to understand it?
Kariya Matou was puzzled as to why he couldn't understand Sakura's behavior.

Whether it was the meeting that took place at the Matou residence not long ago, or Sakura's choice for the future.

This man is completely unacceptable...unacceptable.

Sakura seems to be walking down a very dangerous path.

This is what Matou Kariya was able to perceive through his intuition.

Out of the corner of his eye, Yan Ye looked past the obstructions in the living room at the old man kneeling on the cushion.

Sakura's acceptance of some things brought Kariya a sense of relief, but also anger.

Even if the other party has the intention to atone for their sins, they will still be used up completely in the Sakura Project.

but……

"Don't you think Sakura looks like Sakura anymore, Uncle Kariya?"

The purple-haired girl grew up to be only slightly shorter than Matou Kariya.

Sakura Matou stepped forward and straightened her uncle's slightly disheveled haori.

“No, Sakura can be whatever she wants.” Kariya’s expression turned serious. “As long as it’s Sakura’s own choice, I will support her.”

"Is that so... Uncle Kariya is still the same as before."

Matou Kariya's words seemed to evoke similar feelings in Matou Sakura.

A warm illusion seemed to appear before her eyes, in which she became so small and thin again, while Uncle Yanye became tall and strong once more.

The air grew quiet, and although they stood very close, they were both lost in their own memories.

"In short, no matter what Sakura plans to do next, I may not be able to protect you for the time being."

However, the rambling that was originally intended to continue was stopped when Yan Ye recalled the moonlight on the first day.

Without a doubt, Sakura now possesses the power to protect herself.

And it was precisely on this basis that Kariya was able to leave—

He's becoming increasingly inclined towards [Matou Kariya].

Not only memories, but even the body will show scars as one's "soul" becomes disordered.

The memories of this child growing up are gradually fading away in this body.

If it weren't for that glint of light from the blade, and the unforgettable moonlight that constantly reminded Yan Ye of his origins, Yan Ye would have repeatedly teetered on the brink of "death."

Kariya didn't want to say it that way, but his "mental image" was trying to influence the world itself in return.

At this moment, Yan Ye undoubtedly possesses a true "destiny".

"If I weren't facing a grown-up Sakura, I might already be dead."

The life that belongs solely to [Matou Kariya] has been haunting this person like a ghost, and this has been even more so after Sakura took his Command Seals.

Regardless of their fate, they all yearn for Yan Ye's death.

He intends to use this to control the Matou Residence, causing its shadows to spread from the future's history into the past.

"Uncle Yanye, you won't die on the ship, will you?"

Sakura directly saw through Kariya's thoughts—

Compared to his own constant attempts to find opportunities, Uncle Kariya seemed to have abandoned any thought altogether.

This idea is not difficult to understand.

Zouken Matou is theoretically still alive, and Sakura Matou is also still alive.

[Fate] wants to use Kariya's death to bring about the end of the Fourth Shinobi World War or the beginning of the Fifth Shinobi World War.

If Kariya makes the most extreme and irreversible mistake—such as dying in a place he shouldn't have—then Sakura will definitely be able to break free from her fate.

What if it wasn't Saber who killed the Sea Demon, but myself?
What if it wasn't Kiritsugu who obtained the Holy Grail, but himself?
Regardless of whether he can truly achieve this, Kariya is confident that he can prevent this "historical inertia" from returning to its original course.

This is also why Sakura didn't want to talk to Kariya any longer; she had already received Lin Sheng's orders.

It is not feasible to completely deviate from the historical inertia of either World War IV or World War V.

This is because it involves whether we can directly assume that this universe is the very first universe.

……

Unlike other entities that may be affected by historical inertia.

Whether it's the original Sakura or the now-grown Sakura, they shouldn't theoretically exist, so there's absolutely no possibility of them leaking information.

Given that the complete plan does indeed require Sakura Matou's cooperation, they know more information than others.

Not long ago, Lin Sheng's voice rang in Matou Sakura's ears, telling her about this somewhat cruel reality.

"Given that there are many 'strong' beings in this universe who have deviated from the historical inertia, we do indeed have a need to make use of the historical inertia."

"In the words of the Type-Moon universe, this is a grand magic trick that swaps our universe with all other universes."

On this point, Lin Sheng and Conan are in complete agreement, except for their different levels of emotional acceptance.

Because there are just too many "powerful beings" in this "universe".

No one knows what the situation is like outside the [Realistic Marble].

Even if Merlin guarantees that Jewelcrafter won't reveal the situation here, what about the others?

The world today is an "information black hole" that only takes in and never comes out.

The Alliance not only lacks any means of observing the outside world, but also, given the growing evidence that the Alliance has been under the watchful eyes of certain individuals from the very beginning.

"We need to eliminate these unexpected factors." Lin Sheng's words sent a chill down Matou Sakura's spine.

For the Alliance, the power to break limits is the path to chaos.

Without these "strong" individuals who randomly entered the fray, the Alliance's work on this universe should have proceeded much more smoothly.

One of the differences, or rather the most important difference, between [historical inertia] and [compilation matters] lies here.

Which one is the true "main branch," and which one is the maintenance matter that can be recognized by the "mechanism," is undoubtedly determined by "historical inertia."

"As long as our universe is recognized enough by the inertia of history, and even actively amplified."

Things that do not conform to the "historical inertia" will disappear.

In other words, if successful, the Alliance will do something far more extreme than Chaldea.

Anyone who hears this statement for the first time, which is no different from "erasing the multiverse system," will think it is fanciful or feel a chill down their spine.

"Of course, we can't succeed." Lin Sheng's next sentence finally made Matou Sakura breathe a sigh of relief.

Based on Lin Sheng's description, this seems highly feasible.

Perhaps the Alliance doesn't know how to use effects to change or enhance historical inertia.

But didn't Chaldea already do that once with the help of the Holy Grail?
“Because you won’t agree, Sakura.” Lin Sheng smiled. “Conan also said that my method is a bit too extreme.”

But the next moment, Lin Sheng's expression turned serious.

"However, we need to make others feel that we are serious."

The most important reason why nuclear deterrence can be successful is that it makes the enemy confident that if they do something, the other side will definitely press the launch button.

"This plan must be at least 99% complete, or even 100% complete before those people come forward."

Sakura Matou had only one question: "What if those people still refuse to compromise?"

Unlike conventional nuclear deterrence, historical inertia is undoubtedly constantly evolving.

In other words, this is actually a nuclear bomb that can only be launched once.

"Then you must truly complete it." Lin Sheng's reply left no room for negotiation.

To be honest, Lin Sheng was genuinely disappointed with this [Type-Moon Universe-001].

The situation they face is countless times better than what this universe has ever faced before.

Considering the vast "degree of freedom" of this universe.

Fujimaru Ritsuka's plan may not have been entirely successful, but the ending was by no means a bad one.

"I think that's one of the reasons why she felt at ease leaving."

Lin Sheng could come up with countless ways to turn this "universe" into a happy place like the "Fantasy Carnival".

"The Holy Grail doesn't restrict how you obtain it; it will appear as long as the ritual is successfully completed."

"In other words, theoretically all the 'strongest' can truly share countless wishes."

"The Throne of Heroes will always exist; what needs to be sacrificed is the immense magical power of the heroic spirits that are sent down."

"They could have easily resurrected all the victims at the end, or even retrieved them directly from the [Inner Sea of ​​Stars] or the [Outer World]."

"Even if we let the original historical momentum continue, the outcome won't be too bad."

At least, it's not as bad as Kiritsugu saw in his dream.

"So, if none of them step forward to stop this, and instead they all think that someone else will do it, or that the Alliance would never do such a thing."

“Matou Sakura, the [Alliance]’s order is for you to activate it.”

"What will happen as a result?" Matou Sakura asked.

“Apart from the historical inertia of World War IV and V, all of it will disappear,” Lin Sheng stated his assessment.

Sakura Matou is not a person who is overly compassionate.

But my older sister, who is also known as [Great Matou Sakura], once mentioned a few things in a casual conversation—

For example, the fact that she once gave a happy ending to her parallel universe counterpart.

“What about those universes that had a happy ending?” she continued.

“I don’t know.” Lin Sheng wasn’t just giving Matou Sakura a perfunctory answer. “Actually, according to the Alliance’s speculation, doing this would directly trigger the mechanism, and the shell would eliminate everything that doesn’t conform to its content.”

"In theory, even the [Alliance] is within the scope, but we will temporarily separate from the [Shell] and exist in the imaginary space as a 'possibility'."

"Those ones--"

“Those ‘strong ones’ couldn’t do it,” Lin Sheng explained, “because the Alliance didn’t escape to the imaginary space, but rather used the imaginary space to conceal its ‘separation’.”

"It's complicated to explain in detail, but if they did that, they would really disappear—because in the context of historical inertia, they have never done it before."

"Furthermore, since this event is also a result of the power of historical inertia, it will be similar to a prophetic machine—I mean, it will become an undeniable benchmark."

"And if you press the button, then [Alaya] will become something like [Compilation Matters] or [Human Reason], and it will not deny this matter."

For a moment, Matou Sakura really wanted to do it according to this plan.

She had initially felt regretful about those universes with "happy endings," but now she finds this outcome acceptable.

Unlike Matou Kariya, who only cared about herself, Matou Sakura was more committed to upholding justice.

Even though that would undoubtedly result in some sacrifices.

While this is related to the fact that most people in the Type-Moon universe tend to go to extremes, it's more likely that Matou Sakura does indeed have a similar feeling.

This feeling of the "strong" arbitrarily manipulating the weak, and shaping the universe based on personal preferences and will, is indeed tiresome. The difference lies largely in the distinction between dealing with individual evil and the evil of nature.

This is undoubtedly a "quick win" strategy: smash an old world and then rebuild a new one.

In fact, if the Alliance were to actually propose doing this, it might receive even more support than it currently seeks to have the best of both worlds.

After all—who wants to have it both ways with someone they perceive as their enemy?
“Therefore, you also need to pay attention to the people who actively promote this—at least [Alaya] will definitely not oppose this plan,” Lin Sheng reminded him.

Moreover, he immediately followed up by saying that he would definitely make Matou Sakura give up on actively implementing this plan.

That's the sacrifice that needs to be made for this.

“You, your other self, Kariya Matou… If you actually carried this out, apart from the members of the Alliance itself, none of you could possibly survive.”

"Because Alaya cannot allow people from before the 'reboot' to exist, which means that at that point, you will have no choice but to leave this universe."

Before Matou Sakura could even subconsciously show her joy, Lin Sheng added:
"If your origin is not properly programmed in this universe and the beacon is not completed, you will randomly fall into another shell universe."

Lin Sheng insisted that everyone who carried out this plan must have given it careful consideration, and even make sacrifices when forced to.

Although I feel the urge to do this out of disgust, it's like the saying, "Your head isn't a leek; once you cut it, it won't grow back."

"If this matter is truly accomplished, there will be no room for regret."

……

In fact, aside from not informing Matou Sakura:

The universe that fell randomly may not be random, nor is it the [Type-Moon universe];
She was not the only one responsible for obtaining the Holy Grail and making a wish;
The Alliance has reached a preliminary cooperation agreement with Alaya or the reinforcements (without prior communication).

Aside from a few other "details," Lin Sheng didn't hide much.

The reason he and Conan dared to make such a radical and daring plan was that the [Alliance] had finally made a breakthrough in their plan to bring Hasegawa Tsuki back.

The Alliance in this universe is currently preparing the beacon to bring Hasegawa Tsuki back.

In the third cycle of this universe, at the end of the sixth pointer case.

With the Möbius strip cycling once again.

The moment [Conan Edogawa] puts on the six-pointed [Cosmic Narrative Engine].

Under everyone's watchful eyes, Ms. Miyano briefly disappeared and then reappeared within the [Cocoon System].

The next moment, the entire Third Central Research Platform was shaken by a huge wave of cheers.

"It's a success!!!"

Based on the differences in different [element axes], the plan to travel between different [conan worldview universe shell universes] was finally successful.

"As expected, Conan's watch, when truly 'fully equipped,' can utilize the [mechanism] to rescue people." Bai Zichen stared at the instrument used to monitor the RSI index.

Considering the "old man's" experience and understanding, he was also transferred to the Narrative Studies Department to help out during this period.

This experiment began after Conan and Rinno were convinced that Hasegawa Tsuki's deviation was related to the "core".

According to the research of the Narrative Studies Department, regardless of which element of the Type-Moon universe Hasegawa Moon was retrieved from—

Some of them, who are somewhat obsessed with the narrative layer, genuinely believe it has something to do with the word "moon" in the name.

However, regardless of the circumstances, the number of elements that overlap between Hasegawa Moon and the Type-Moon universe will certainly not exceed the number of elements that overlap with the current universe.

Since the CYZ effect can be anchored based on different directions of the [feature axis] and used as coordinates for direct transfer.

Bringing Hasegawa Moon back would also be feasible.

This is indeed a very amazing phenomenon—

His discoverer directly won the Alliance's highest effect research award for the Third Cycle, as well as a prize of 33 strings for the CYZ effect.

The theory that there is no gap between the two shells, but only a distinction, has been verified.

"The CYZ effect does not transfer between shells. After all, if there is no such thing as 'distance,' then the so-called 'transfer consumption' is nonsense."

The researchers who validated the theory stated the following in their research report.

“We can imagine a worldview cluster—whether they are the same or not, they all belong to the same element, and the worldview cluster is itself a broader element.”

“It sounds a lot like the Grand Unification Theory,” a scholar in the audience whispered to his assistant.

“It’s a very ambitious theory, and we could certainly try to use that to scam some funding.” A researcher at a certain institute who was struggling to raise funds also pondered this.

"Effect values ​​can be transferred arbitrarily and without loss within the same element axis in the same universe."

"So, what exactly is the 'force' that the effect exerts on what causes the different losses between [Detective Conan Universe-002] and [Type-Moon Universe-001]?"

The speaker paused.

"After all, we all know that the effect value will not decrease without external obstruction."

"There is no distance between the shells, and nothing exists that consumes it in the process. Therefore, the real command is actually imposed on the 'effect' itself."

"Just as people from different time dimensions can overlap on the same spatial coordinate, the effect value is equivalent to commanding oneself to change a perspective, like turning around to see the scenery behind.

"It shifts its own [element], and this shift allows it to immediately appear in the same [universe] as the shifted [element]."

The experiment Ms. Miyano conducted not long ago was a verification of this theory.

She takes advantage of her own characteristics as a "semi-CYZ effect organism".

In the Conan universe-002, after providing the corresponding element axis according to the local conditions, she briefly appeared in the Conan universe-002 as her own element deviated.

Therefore, the method to bring Hasegawa Tsuki home is somewhat similar.

All I need is for Conan to bring her back.

Yes, Conan must bring Hasegawa Tsuki back.

This undoubtedly surprised many researchers.

They originally thought that after this theory was initially verified, the next step would be the completion of the "bridge project" to connect the shells.

But this is not the case.

The reason why Ms. Miyano had to return after only a brief visit was—

She almost really became [Akami Miyano].

This brought attention to Dr. Liangliang's theory of "RSI=100 dead line".

"Ah! That's very simple. It's just an analogy to the difference in chirality."

Dr. Liangliang gave a very simple example of the difference.

"The left and right sides are reversed in the mirror, so if the reflection in the mirror is conscious, they can quickly realize the same thing."

He placed his two hands on top of each other, leaving some space in between.

"Let's assume that the center of these two hands is the plane where the RSI value is 100."

Then, he made a rotating motion, aligning the fingers of both hands with each other.

"If this is how the effect works, making them look the same when they face each other, then how do you cross the space in between?"

"After all, the use of effect values ​​means a decrease in RSI values, and the more they are used, the easier it is to approach zero."

Meanwhile, in the other universe, without interference, its RSI value is theoretically always approximately or higher than 100.

"Furthermore, the RSI value is based on 100, so it is actually a relative value and will change based on the degree of the other [feature axis]."

This explains to some extent why the Alliance's explorations have so far rarely encountered duplicate Shell Universes.

The element axis can be subdivided infinitely.

Just as you can be precise to an infinite number of decimal places, you can be precise to the exact same degree as the universe itself.

This leads to a paradox.

If the [feature axis] of the destination is accurate enough, it means you are already at the destination.

However, if you want to move to another location, because you are already inside a "shell," you cannot be completely precise.

The Alliance cannot use thousands or even tens of thousands of effect values ​​to "custom-make" an identical "universe" for one person to transfer to.

Even doing so is impossible in itself.

Taking the "this universe" as an example, Conan may not have any objections, but the "shell" and the "mechanism" probably won't be ignored.

"Therefore, the help of the [core] is necessary."

"Because the elements of character design and the elements of historical inertia are different, they cannot be equated."

Just like Conan Edogawa can still demonstrate his "conology power" to a certain extent in the Type-Moon universe.

Bai Zichen explained, "Elements that rely on the shell are prone to problems due to changes, but those that rely on the character design are not."

"At least, at the moment when Detective Conan appeared, these differences were negligible in the face of his unmeasurably high RSI value."

In this situation, Conan, as the "core," is essentially never to have left the "universe" under certain conditions.

And so, it's not just Hasegawa Tsuki that's affected.

If they are able to use the full power of this universe, Lin Sheng and Conan will work together.

All members of the Alliance recruited in this Type-Moon universe will be transferred at once to the simulated universe on the other side of the Möbius strip, which contains certain Type-Moon elements.

This is why, if the plan is completed, [Type-Moon Universe-001] will definitely "return to its original state".

According to Lin Sheng's estimation, even if Conan merged with his counterpart in this universe at that moment, the "shell mechanism" of the Type-Moon universe would still take it very seriously.

At that point, it wouldn't matter how many effect values ​​Chaldea had.

In fact, if you don't want the mechanism to be fully activated, the less resistance the better.

After Lin Sheng and all the official members of the [Alliance] evacuated, only Lin Sheng remained.

Lin Sheng will act based on the strategy of "observation results" and "saving as much as possible"—

Of course, this undoubtedly means that the Alliance will truly abandon this universe.

In fact, Conan originally wanted to make some more efforts.

But in Lin Sheng's rebuttal that "they have been given enough opportunities," he ultimately acquiesced.

because--

In this plan, the Alliance has absolutely done its utmost.

Just like God's true judgment, the final arrival of the "fire of Sodom" could not be concealed in any way.

As long as there is even one righteous person among the countless "strong" beings in this [Type-Moon Universe].

Even if there isn't a single good person among them.

As long as they aren't hopelessly stupid, the Alliance will give them as much time as they want to figure this out.

Lin Sheng never breaks his promises.

but--

These people need to prove to themselves that they are worthy.

Especially these "strong ones".

They have theoretically broken through the barriers of ignorance.
