Alchemy Principles of Type-Moon World

“…” The young man remained silent and continued walking forward without looking back.

He didn't know where he was going, so he just wandered through the empty streets, his footsteps echoing in the empty streets, as if fighting against the approaching dusk. A gentle breeze blew, bringing a hint of coolness. The afterglow of the setting sun dyed the streets golden, and long shadows stretched and twisted on the ground, highlighting his loneliness and confusion.

Alex turned his head at an intersection and looked behind him. The devil still kept stretching out a hand towards him.

Alex finally stretched out his hand, revealing the scarlet Command Seal on the back of his hand, and shook the hand of the Air Flag Ghost.

"Very good, very good." A smile appeared on the devil's dark face, with a cunning glint in his eyes. "Then the contract is established, My Master."

"What's your name?" Alex asked suddenly.

"You can call me Bruce. This is the name my good friend gave me. I like it very much." Bruce said with a smile, "Of course, you can also call me Faust, or -"

"--Like that fellow Goethe, who called me Mephistopheles."

————————————————————

Ringo Mizuki and Patricia hurried through the airport hall, their suitcases dragging behind them making a soft scraping sound on the floor. Their pace blended in with the hurried crowd in the hall, yet their expressions were clearly much more nervous than most passengers.

A petite figure quietly stalked beside them. He wore sunglasses, a mask, and a dark cap, completely obscuring his face. Despite his efforts to maintain a low profile, the uneasiness and furtiveness of his steps were hard to miss.

At the boarding gate, as boarding time approached, the man suddenly leaned close to Patricia, lowered his voice, and asked hesitantly, "Um, do we really not need to tell the organizers about this...?" Her voice was cautious and uneasy, as if she still couldn't completely get rid of the doubts in her heart.

"But, isn't it too late?" Patricia glanced sideways at the man and smiled faintly, her voice revealing a hint of indifference. "The Holy Grail War has been over for two days. You suddenly open the door and say you're back. Even if you tell the organizers that you are the last Servant, it won't be of any use."

Patricia continued, "Rider's group has already returned the Servants and taken their prizes home." As she spoke, she gently touched the top of the head of the person following them through her cap. "And there can only be one Holy Grail War prize at a time." Patricia's voice was filled with pity and lightness. "Telling the organizers will be useless. On the contrary, it will make you return to the Throne of Heroes—"

"—Then why not stay and see the world with us?" Patricia smiled, and she gently patted the man's shoulder. "It's such a pity to die so young."

The man seemed to have finally let go of his doubts and nodded gently, his tone becoming more relaxed. "Is that so? It looks like I'll have to trouble you for a while, Master."

"It's okay, it's okay," Patricia said with a smile, waving her hand. "In fact, we might need your protection, Okita-san."

There was no mistake. The one following Patricia and Kanzuki Ringo at this moment was none other than Okita Souji, who should have disappeared long ago.

Her soul core had been shattered by Tokugawa Ieyasu's sword, and at that moment, her life was practically over. However, as she and Karna prepared to retrieve the Holy Grail, fate cruelly intervened once again. The fluctuations in the detection information directly destroyed her soul core. The fatal shock must have been like the final judgment, wiping both her and Karna from the war. Indeed, she was "dead," her spirit body dissolving into nothingness and dissipating across the battlefield.

However, the Spiritual Base for this Holy Grail War was crafted using the same method Newton used to create his own Spiritual Base. This involved centrifuging the information from the quantum recording tape and then infusing it into a prepared frame. Essentially, this was not much different from the Alterego method.

This is also the reason why Okita Souji's spiritual base can be transformed into an Alterego simply by returning to the world again. Rather than saying that the spiritual bases of this Holy Grail War are the regular seven professions, it is better to say that seven pure Alteregos without any other information were stuffed into the corresponding frames, strengthening the performance of their corresponding professions.

If we make a rough definition, the jobs of these seven Servants are essentially all Alteregos that "have a good compatibility with the job and thus exhibit corresponding characteristics."

But if a Servant looks like a Saber, appears to be a Saber on the panel, and all its actions and appearance are the same as Saber, then it is a Saber.

Through the injection of additional information, Okita Souji's spiritual base changed. The additional information covered her original spiritual base, and the new spiritual base made her "unlike Saber", thus returning as an Alterego, allowing the Demon God (human) Souji to descend.

In other words, what does the fatal blow to Okita Alter's personality have to do with me, Okita Souji? Although Okita Souji's spiritual base is intertwined with Okita Alter, she still retained enough independence at that fatal moment to survive the chaotic spiritual base collapse.

She had indeed suffered a severe injury, staggering out of the ruins of Nijo Castle, her broken body almost dragging her consciousness into the abyss. Finally, she collapsed and passed out in a dark, deserted alley in Kyoto.

If this were some kind of Japanese light novel, perhaps there would be an Asahi Japanese boy who opened the door early in the morning and found a scarred beautiful girl unconscious in front of his door, thus starting a love comedy -

——Unfortunately, no, Ms. Okita was woken up by the cold and no one found her.

When she finally opened her eyes from the cold ground after a day of coma, the pain all over her body made her almost unable to move. She struggled to stand up, her legs and feet weak and her limbs stiff, but she still gritted her teeth and returned to Guanyue Ringo's home.

The words "I'm back" startled both of them.

"By the way," Patricia suddenly turned around and asked as she was about to enter the plane's cabin, "Are you sure your magic power isn't coming from the ley lines? If that's the case, you might not be able to leave Kyoto."

"No problem, no problem," Okita Souji patted his chest. "Thanks to that guy, I've inexplicably gained a skill in my spiritual base that allows me to act independently. I don't need to rely on external magic power to maintain my existence!"

"And, in Group 4 Chat n!①鸸凌彡二铃废是八且!" Okita Souji became more and more excited as he spoke, "It seems my weakness has been overcome. I haven't felt it triggered in two days!"

"Is that so? If that's the case..." (锍铃?/〨II》陾傘（?四）?" Patricia thought to herself, "With you as my bodyguard, it shouldn't be a problem to explore further..."

"Eh, what?" Okita Souji asked, "Are you going on an adventure somewhere?"

"Well... we'll see how things go then," Patricia said as she took Ringo Mitsuki off the wheelchair and placed her on the seat. "Anyway, let's go back to South America and take a look."

"Ms. Okita's new life is about to begin!" Okita Souji waved his arms, "A! A! O!"

Patricia wasn't Japanese, so she couldn't understand what Okita Souji was trying to say, and beside her, Ringo Mitsuki was in a coma.

——So naturally, no one answered.

To be honest, I don't really like the way Mephistopheles is portrayed in FGO. It's clearly a work about humanistic awakening, but he's portrayed as a rather thin pervert. In the original novel, when I saw Faust indulge in lust right from the start, I couldn't help but call him a vulgar lecher.

It's clearly a magical worldview, but Mephistopheles was interpreted as a dream spirit! 厁II０qi(IV) Alchemist and artificial life form, which was reversed and downgraded, but that's okay.

So I changed my approach, using Goethe's Mephistopheles as my subject. Furthermore, 27club founder Johnson was rumored to have contracted a Mephistopheles devil. Combining these legends, I constructed a character whose character isn't about trading souls for musical talent to achieve fame, but rather about being drawn to someone's music and tempting them to abandon their spiritual roots with the promise of material fulfillment.

Although we admire these souls, we tempt them to fall into material desires. We feel pain because of the pain they face in reality, and we feel happy because of their resistance in the pain.

The above is a new book by a new author. Please vote and give me feedback. Thank you!

Volume 49: The Kyoto Holy Grail War Without Nagging: . The Final Blue Truth

Xing Qingqiu was sitting on the plane at the moment. The blue sky and white clouds outside the window seemed to be very close, making him feel happy.

He lowered his head and concentrated on organizing the manuscript in his hand, his fingertips wandering over the paper, feeling the warmth of the ink.

The basic composition of spirits had been clarified, albeit still within the realm of mystery. Without understanding the true nature of magic, Xing Qingjiu could hardly claim to have broken the barrier between mystery and science.

However, the progress is still very encouraging. Originally, Xing Qingyu thought he would have to do research for a few more years.

After all, what he observed in the Holy Grail War was too deliberate. The emergence of macroscopic quantum superposition allowed him to observe every detail from a macroscopic perspective while also observing its structure as a whole. If this kind of thing happened in a laboratory environment, Xing Qingjiu would have to stay for at least a few years before getting any results.

This is already considered rapid progress. What was seen and gained in this Holy Grail War is simply a miracle that cannot be replicated. Xing Qingjiu did not let this miracle down. The remaining work is just to do more empirical research to verify its universality.

Xing Qingqiu put away the manuscript in his hand and placed it carefully in the bag beside him. Then he took out a stack of letter paper from his pocket and read it again. From the marks on the letter paper, it can be seen that it has been read over and over again many times.

That was what Xing Qingfu got from the nurse when he came to the hospital. According to the nurse, the letter was placed in the bandage on Kiritsugu Emiya's chest, and the envelope specifically stated the name and asked him to open it personally.

"To my Master," Xing Qingqi read the words above, "I'm sorry for doing so many things without telling you. No, it shouldn't be considered a secret. After all, I told you that I would give you a surprise."

That was indeed a surprise. Xing Qingyu couldn't help but think so every time he read this passage. The job Schrödinger gave him perfectly made Xing Qingyu feel surprised and happy.

"When you read this letter, if nothing unexpected happens, I should be spending the night with Heizi, so you don't have to come to me. I will find you myself in the morning and explain everything to you."

"Of course, if something unexpected happens, I shouldn't die immediately. But if I have to give these precious last moments to a man like you? Oh, forget it. It's more suitable for me to die in a woman's bed."

"That's why I wrote this letter. If I can't go back, this letter will also explain what I feel I should tell you."

Schrödinger did not come back, and he even maxed out his credit card before he died. Xing Qingyu really couldn't imagine how much this old man spent in the nightclub.

"First of all, congratulations on independently understanding the concept of spirits. While you're still a bit behind geniuses like us, you can be proud of it. In fact, even without my help, judging by your lab notes, your research direction is on the right track, and you'll be able to complete the understanding of spirits sooner or later—"

"—But I don't have the time to let you take your time. It doesn't matter if I'm a dead guy, but I don't think you can wait another hundred years."

"This may be a little difficult to understand. Let me explain it this way. In addition to the observer interpretation, quantum mechanics also has a multi-historical interpretation. Let's temporarily acknowledge the existence of this interpretation. From this point of view, I need to explain two concepts to you:"

"First, accepting a multi-historical interpretation means we must acknowledge the fact that history is also uncertain. History is uncertain, the future is uncertain, and the only thing that is certain is the present."

"So, after accepting this fact, we can draw a corollary: since our actions can change the uncertain future that has not yet arrived, why can't we change the equally uncertain past?"

"Because history can be selected, a mechanism has emerged to counteract historical selection. This is the first concept, 'humanistic foundation,' which prevents historical selection by fixing historical nodes that are easily changed by observation."

"If there are no special historical nodes, then each fixation is usually done once every hundred years, that is, at the turn of the century."

"Humanity doesn't care what choices you make, nor does it care what the consequences of your choices will be. Humanity simply conducts a screening at each time point, and only IFs that can still last a hundred years into the future are allowed to continue."

"If the possible outcome of a choice stretches out for less than a hundred years, it is judged as a world line without a future and is cut off, signifying the possibility that human history no longer exists. This is the second concept, 'cutting off events.'"

"I only heard from the Guardian of Inhibition why Human Principle chose screening. It was for so-called energy conservation. I don't know any further reasons. And I can't prove to you that this phenomenon exists. Everything about Human Principle is just my assumption.

"Speaking of the guardians of restraint, although human reason doesn't care about your choices, there is a mechanism called restraint. For the survival of this world line, they will review and prevent choices that may cause this world line to be cut off—"

"—but they also don't know which actions will lead to shearing. They don't have the ability to observe the future, so the future is also unknown to them."

"Therefore, they will use the simplest and crudest method, selecting a world line as the so-called standard world line. Then, any behavior that would cause a huge difference from this world line will be prevented, either by subtle interference or by directly sending so-called guardians to stop it."

"The only problem is that, according to the guardian, premature resolution of the mystery could also lead to severance. It's said that excessive development could lead to prosperity far beyond its means, so it also needs to be prevented."

"I don't make any comments on this behavior, but the good news is that the inhibitory force, or rather the brains of its agents, are not enough to understand our research. Euclidean geometry can be extended to non-Euclidean geometry after a certain axiom is modified.

"—and quantum mechanics is similar, but it can be expanded to describe mysteries."

"That's pretty much all I have to say. Well, I'll leave the worries to you young people."

"I have no obligation to be responsible to you. Just consider these words as your payment for covering my bills these days. Well, that's enough."

"Erwin Schrödinger, December 1999, 12."

Xing Qingqiu put down the letter. Even though he had read it many times, there was still a lot of information that he needed to digest slowly. First of all, the information in the entire letter was based entirely on assumptions, and there was no actual evidence to support his argument.

—But the author is Erwin Schrödinger. The same Schrödinger who, based on completely unfounded assumptions, deduced the cornerstone of modern quantum mechanics.

Based solely on the talent represented by this name, Xing Qingfeng was willing to take a gamble and bet that his hypothesis was true. But as long as he believed in this hypothesis, he would find that there were too many problems.

Schrödinger summarized the events he witnessed and gave a message in a bottle, and Xing Qingfeng needed to infer the truth in the cat box based on the content of the bottle.

First, why cut off the extra possibilities? Is there any need to do so?

Second, how does human nature cut off unnecessary possibilities? What is the principle?

Third, if there is such a standard world line, and its content and history are not far from the current world line——

So why haven't production relations been influenced by the mystical until now? Why haven't several industrial revolutions incorporated the mystical into production relations? Xing Qingfeng has great faith in those capitalists, and mystical phenomena are not difficult to observe. So why is the mystery still this small-scale workshop-style production relationship?

This world of mystery, of magic, had actually developed in the same way as the world of my previous life, which had no mystery at all? It had developed in the same way as the world without mystery that my teacher had longed for...

...No, why didn't his own teacher, Newton, question the current world? As the face of science's formal counterattack against the mystical occupation of the secular world, he clearly witnessed the First Industrial Revolution. But why, considering science as the foundation, didn't he raise any objections to the barrier between mysticism and science? When he saw modern quantum mechanics, all he could say was sigh—

- If the explanation is that he understood what Schrödinger said, that so-called quantum mechanics can also explain the mystery, then why did he never tell me this from the beginning to the end, but instead supported my independent research on related content?

If we summarize the above questions, then the third question is actually:

Why has the normal development of the standard Wusi Liuba Qi⒎ world line not been mysteriously affected so far?

Xing Qingyu couldn't help but gaze out the porthole at the scenery, using the vast expanse of the sky to soothe his anxiety. He only had so much information at hand. If he didn't limit the number of questions, compressing the information into a limited number of questions, he might not even be able to find a starting point for thinking.

Xing Qingyu wrote down the three questions in his mind on paper, but suddenly he couldn't help laughing as if he had thought of something -

——"Isn't this... what they call 'Why, How, Who'?"

The first question is, why was it done? What is the motivation for humans to cut out unnecessary possibilities?

The second question is, how is it done? What is the method of human judgment for cutting?

The third question is, who did it? What is the identity of the murderer? The answer has been found: it is human reason. But the question remains: why does the mystery seem to have no impact on the standard world line? What exactly is the standard world line?

Humanity killed those world lines that were judged to have no future. The murderers and victims have all been identified.

——No, there is no way to prove that the victim and the murderer actually existed.

In the case that everything is hypothetical, there is no point in discussing How. Without more evidence to break the cat box, Xing Qingfeng can come up with countless hypotheses to make How's logic self-consistent.

——Logical consistency does not mean truth. The information given in Schrödinger’s letter cannot provide any support for the method. The second question is meaningless for the time being.

Only "Why" and "Who" remained. Xing Qingfeng pondered for a moment and decided to start with the simplest question, "Who," which had the most doubts but the most known information. There was a simplest explanation for this question:

——Because everyone in the standard world line is a fool and turns a blind eye to the mystery before them, the mystery does not interfere with human development.

Although this explanation is full of arrogance, it is still valuable because both the information provided by Schrödinger and the content pointed to by this explanation are actually consistent.

——Mystery has not interfered with human development, at least until the year 2000 AD. The historical development of a world with mystery and a world without mystery is not much different.

Anyone with a sound mind would find this absurd. Even in modern times, when mysticism has receded, magic would still have a profound impact on productivity, yet the ultimate manifestation bore a striking resemblance to the history of one's past life. Thinking of this, Xing Qing couldn't help but laugh.

This only proves that, for the standard world line, the existence of mystery is the same as its non-existence. Yes, Xing Qingfeng has no way to disprove the possibility that mystery also exists in his original world.

This is the Probatio Diabolica. If Xing Qingfeng wants to prove that there are mysteries in this world, he only needs to perform a magic trick.

But if Xing Qingfu wants to prove that the mystery did not exist in the world before he traveled through time, he must search the entire world and find no trace of the mystery in order to prove that the mystery does not exist. This is as difficult as proving that an invisible fire-breathing dragon in a garage does not exist.

The existence of conspiracy theories and religions depends on this. If it is impossible to disprove the non-existence of the so-called "Illuminati" or "God", then even if it is impossible to provide evidence of their existence, it is impossible to completely disprove them.

The mystery hides in the gap between existence and non-existence, which cannot be proved or disproven.

Is the reasoning going to come to a deadlock here?

"Use Occam's razor..." Xing Qingfeng muttered to himself, his thoughts swirling in his mind. "No, we need a razor sharper than Occam's razor—"

"—Let's use Newton's flaming laser sword, hahaha." Xing Qingfeng couldn't help laughing when he thought of the name. The sound echoed in the cabin, attracting the attention of several passengers. "Any problem that can't be solved through experimentation or observation is not worth arguing about."

"If you use the teacher's flaming laser sword to destroy the mystery of your past life, you will gain this truth."

"There are no mysteries in the standard worldline," he muttered, tapping his fingers lightly on the table. "I always feel like the blue word 'real' would be better here, hehe."

Based on this answer, we can smoothly deduce the answer to the extended question, that is, the mechanism for judging whether there is a deviation from the standard, that is, the influence of mystery must not shake the key historical nodes, so that the historical development with mystery is consistent with the historical development without mystery.

Then, the identity of human reason can be explained: human reason is the human reason of the standard world line. Any choice that relies on mysterious deviation from the standard world line will be regarded as a rebellion against human reason. The higher the degree of rebellion, the higher the probability of triggering the so-called shear.

"What the hell..." Xing Qingfeng found it increasingly unbearable the more he thought about it, and the smile on his face gradually turned bitter. "Is this a joke? Is this what they call, even though miracles and magic have appeared, the development of history is still constrained by rigid reality...?"
