Alchemy Principles of Type-Moon World

Emiya Kiritsugu felt a little melancholy.

He stood at the window, gazing out at the silent forest on the outskirts of Fuyuki. Night fell, the stars sparse, and the chill of early winter swept silently across the wilderness surrounding the castle. There was no trace of snow in the air, but the chill had already penetrated every inch of his skin, making him shiver. His thoughts drifted with the cold wind, recalling the past few days.

He began to reminisce about the days he and Ellie had spent in his homeland after abandoning the Holy Grail War. A heart that had once thought itself hardened to stone suddenly felt a surge of warmth. Those peaceful days, Ellie's smile and her warm hands, always managed to temporarily dispel the gloom within him.

It would be nice if I could bring Illya over to live with me in Fuyuki.

When Ahad, the old patriarch of Einzbern, learned that Newton would go back with them, his tone on the phone did not sound fluctuating. He just said lightly that he understood.

But it wasn't until last night when the old patriarch called again that Kiritsugu Emiya realized something was wrong.

"Kiritsugu, I want to ask you, who did you commission to lay the telephone lines?" A slightly hurried and hoarse voice came from the microphone. Emiya Kiritsugu could almost imagine the old man stroking his long beard like a waterfall of pure ice, and staring at him with a strong gaze that showed no sign of aging from his deep eye sockets.

Even though Emiya Kiritsugu wasn't right in front of him, the almost paranoid pressure still emanated from the microphone, making him feel a little disgusted and uneasy. He looked out the window. In the darkness, the branches of a few dead trees swayed in the cold wind, as if whispering something.

"I laid it myself," Emiya Kiritsugu replied, his voice slightly strained. He didn't particularly enjoy communicating with the old patriarch. "Einzbern Castle isn't open to the public, so I had to do it."

"...Is that so." Ahad sighed barely audibly. "Did you also complete the electrical installation?"

"Yes, if we only have a generator, laying it out won't be difficult." Emiya Kiritsugu tried to keep his voice calm, but the ominous premonition in his heart grew stronger. He looked out the window again. The night wind rustled the fallen leaves, as if accompanying his uneasiness.

"If we want to complete the arrangement of these things in Einzbern Castle and make it able to accommodate them, will two days be enough?"

"This..." Kiritsugu Emiya was a little confused. When he wanted to install telephone lines and generators in Einzbern, he had a big quarrel with the old patriarch. This is how magic families with a long history are. They don't like this kind of modern equipment.

But why did such a tough traditional magician suddenly change his temperament?

"That probably won't be enough," Emiya Kiritsugu thought for a moment, "If we completely renovate Einzbern Castle, it will take at least half a month."

"..." The old man on the other side of the microphone was silent for a long time before he continued to ask, "If it's as you said before, how long will it take to set up that special line?"

A single telephone line alone couldn't meet Emiya Kiritsugu's needs. It couldn't even send a single email instantly, let alone send and receive data. Emiya Kiritsugu had wanted to get another dedicated line to connect to the Internet, but Ahad sternly refused.

"Has the old patriarch, who was furious because I brought a computer into the Einzbern household, changed his ways?" Emiya Kiritsugu was puzzled, but still replied, "It wouldn't take much effort to simply set up a dedicated line."

"Okay, you send someone over, and it'd be best if everything is arranged before tomorrow night." The old man made the decision immediately, regardless of Emiya Kiritsugu's opinion.

"Then I'll let Maiya go back and make arrangements first..." Emiya Kiritsugu was about to hang up the phone, but was stopped by Ahad.

"Also, teach me how to use this thing called... computer? Is that how it's pronounced? How do you use this thing?"

Emiya Kiritsugu froze, staring at the microphone in disbelief. He rubbed his brow helplessly, pondering how to handle this sudden task. Ahad was, after all, a stubborn old magus, and teaching him how to use modern technology was a bit of a torment.

He stared at the night view outside the window and sighed melancholy.

"Here." Xing Qingqi was holding a paper bag filled with freshly made crepes. "I prepared some food for breakfast."

It was a cold morning at Fuyuki Airport. The wind was frost-laden, the chill air tinged with a hint of moisture. The airport lobby hadn't yet fully awakened, and a sparse stream of passengers, dragging their luggage, hurried across the tiled floor, which reflected the incandescent light. Xing Qingfeng wore a heavy, dark blue coat, his scarf wrapped high around his neck, obscuring most of his face. The only eyes that were visible were a hint of weariness.

He didn't bring much luggage with him. He originally planned to take all the used textbooks back with him, but after thinking about it, he decided to leave them all to Shinji Matou, and told him that he only needed to understand one book before coming to him to learn magic.

Shinji Matou's eyes lit up at the sight of a box full of books, and he couldn't wait to jump in and experience the beauty of "magic." He really hoped he would be this happy when he saw these books when he grew up.

"Japanese crepe?" Kenneth pulled one out of the bag and carefully examined the layers of crepe wrapped in fresh cream and matcha sauce, as if studying its structure. "The Japanese always like to make some strange improvements."

Xing Qingqi yawned, as if he hadn't gotten enough sleep. His hair was a little messy, with a few strands hanging down in front of his forehead, reflecting the hazy morning light. "This was made by your students. Weber is selling crepes to earn money for his plane ticket."

"Has he decided on the travel route?" Kenneth asked with a hint of curiosity in his eyes.

"Yes, first go to China, then to India, and then reverse the route of Alexander the Great's eastern expedition, and finally arrive in Macedonia." Xing Qingfu said, his voice a little low, as if he was not fully awake yet. "Originally, China was not in his plan. He said it was difficult for Western magicians to come to our country. But then he inexplicably said that he wanted to go and see it first."

Soft music mingled with the occasional boarding reminder from the public address system in the terminal. A coffee shop in the distance opened for business, and the aroma of coffee wafted through the warm air. Xing Qingqi picked up a crepe and took a bite. The sweet, creamy flavor melted in his mouth, forming a stark contrast to the chilly air.

"Then I told him to save up enough money first," Xing Qingwu smiled, his eyes slightly raised, with a hint of joking, "I said that with his cooking skills, no one would eat his food in China. If he wants to continue saving for the trip, he may have to work as a screwdriver."

"Not bad, after all, that kid in the Clock Tower looks like a hothouse flower that's never seen the world," Kayneth muttered contentedly as he took a bite of his crepe. "If he doesn't suffer a little, it'll be hard to order him around when he returns to the Clock Tower."

"I think you two are about the same." Xing Qing shook his head and changed the subject. "Come to think of it, didn't you say you were going to take Ying away? Why haven't I seen her?"

"That child... the only one she can trust right now is Matou Kariya," Kenneth said, his tone tinged with helplessness and a hint of worry. "Rather than being taken to the world of magicians by me, it's better for her to live a mediocre life."

"So I put a little restriction on her to prevent her from being targeted by some unscrupulous magician."

The sky outside the airport gradually brightened, the faint light of morning sun filtering through the glass windows onto the ground, and the entire hall gradually woke up from its slumber. The hustle and bustle of early morning began to fill every corner.

"Really? I hope the child can get better." Xing Qingyu looked at the sky outside the window, a hint of tenderness in his eyes. "It's really hard for him to go through such a thing at such a young age."

The airport's broadcast system sounded again, reminding passengers that it was time to board their flight. Xing Qingqi glanced at his watch and frowned slightly.

"Teacher and the others are probably already waiting at the boarding gate. Let's go over there first." Xing Qingyu said to Kenneth. The two of them quickly packed up their things and walked towards the boarding gate.

————————————————————

The early morning at Fuyuki Airport was still shrouded in a thin layer of mist, the chill air making people shiver. The lights in the hall shone through the mist, casting a warm glow that seemed a bit hazy. The footsteps of Xing Qingqi and Kenneth echoed in the empty hall, remarkably clear.

In the frigid north of the German Alps, an ancient castle stands tall amidst the mountains. Its stone walls are aged and sturdy, seemingly bearing the brunt of centuries of wind and frost. In winter, the mountain winds are biting and snowflakes drift down the castle's towers and spires, blanketing them in a blanket of silver, creating a fairytale-like experience.

The castle tower soared into the clouds, overlooking the vast forest and frozen lake below. The surrounding trees were covered in a thick layer of snow, as if wearing a white wedding dress. The cold wind howled past, bringing bursts of chill, making people shiver.

The distant mountains, covered in snow, rose and fell, framing the castle's grandeur. As the sun set, the sky stained a deep crimson, its afterglow shimmering across the snow, creating a dazzling radiance. As night fell, the castle was shrouded in silence, its only light flickering in the windows, a faint candlelight guarding this frozen land.

"Why does it look like there's no electricity?" Xing Qingyu sat in the car and looked at the castle in the distance. "Why does it look more like candlelight than lamplight?"

"It's normal that there's no power," Newton said from the co-pilot seat. "From what Irisviel can tell, these androids are probably still isolated in the mountains."

"Ah... I wonder what the master would think if he heard it." Irisviel said with a smile while sitting in the back seat of the car.

As the car slowly approached, the heavy iron gate creaked, as if centuries of history flowed through it with every opening and closing. The car stopped in the square in front of the castle. The cold stone pavement was covered with a thin layer of snow, and the wheels made a creaking sound when they passed over it.

The car door opened, and everyone got out. The cold air immediately hit them, making them tighten their coats. The castle gate slowly opened, and an old man in a robe, with long white hair and a long beard, walked out slowly and took the initiative to open the car door for Newton.

"Long time no see, Ahad." Newton was quite indifferent. "After all these years, are you still the head of the family?"

Although Newton often talked about the Einzbern family's artificial humans, he said something that left Ahad speechless as soon as they met.

Newton ignored Ahad's response and walked straight into the castle, followed by the others. Ahad followed silently, as if he was used to Newton's attitude.

The castle's interior was adorned with a simple yet ornate ambiance. Ancient paintings covered the walls, each depicting the long history of the Einzbern family. The floor was covered with thick carpets, soft and comfortable to the touch. Candles lit in candlesticks lining the corridors, emitting a gentle glow. The flames flickered gently in the breeze, bringing a warm atmosphere that temporarily dispelled the cold outside.

"After all these years, you've managed to keep the decor almost exactly the same as it was hundreds of years ago." Newton sneered. "It seems the Holy Grail War is one of the few changes you've made?"

Ahad smiled noncommittally, feeling a bit embarrassed, but he said nothing. It was the first time that Emiya Kiritsugu saw the old patriarch's attitude like this, and he felt like laughing.

“Hahaha,” Irisviel couldn’t help but laugh out loud, “This is the first time I’ve seen this side of the Master.”

Newton led the others straight into the reception room. The room was spacious and bright, with a mural on the wall depicting the Einzbern "Winter Saint," accompanied by two magi, each with their hands extended toward a cup in the sky. The composition and design balance clearly indicated the Einzbern family's disdain for the Machiri and Tōsaka families.

In the center of the room stood a long oak table, decorated with fine silver and china, and a roaring fire burned in the fireplace, casting its light on everyone's face.

Newton sat down at one end of the long table, picked up a cup of hot tea, and took a sip. "Ha, even the taste of the tea is almost the same as it was hundreds of years ago."

However, if we talk about the few changes——

In the corner of the room, a laptop sat casually on a heavy oak desk, the two looking as awkward as a sewing machine on an operating table. The computer's silver casing stood out against the rustic oak desk, and the modern interface on the display shone with a cold light, creating a stark contrast to the warm atmosphere of the surroundings.

The long network cable behind the computer stretched unsecured, extending directly outward along the floor. Its color stood out against the room's overall hue. It snaked across the thick carpet like an incongruous snake, stretching from one corner of the room to the window. The old window, once tightly closed, now had been forced slightly open by the network cable. A cold breeze seeped in, bringing a chill.

"Ah, actually, we're not rejecting the changing times." Ahad noticed Newton's attention focused on the computer—in fact, there's good reason to suspect the computer's protruding presence is intended to attract attention—and quickly leaned over and said, "We'll remember your advice, Sir, and keep up with the times."

"For example, I usually use the computer for work," Ahad said, sitting in front of the computer, operating it stiffly. Newton stood quietly behind him, looking like an elder supervising his child's studies.

Although Ahad looks much older than Newton now.

"Then why did you keep making excuses when I asked you to try a video call a few days ago, or when I asked you to email some photos?" Newton asked calmly. "I also want to see the product of the artificial man and the human being."

"Ah... this is because..."

"Due to the terrain of the Einzbern family, the dedicated line froze and broke down a few days ago." Emiya Kiritsugu came to Ahad's rescue at the right time. "The old master called me overnight and asked me to appoint the right person to repair it."

"Yes, because the weather is bad, hahaha..." Ahad was indeed sweating profusely. The Newton in his memory was a serious old man. Due to his indifference to emotions and desires, it was quite difficult to communicate with him.

He never expected that he could relive the feeling of that year hundreds of years later, which made Ahad groan in his heart.

"So, what about the child named Illyasviel?" Newton's fingers kept tapping on the back of the chair where Ahad was sitting, and the tapping sound seemed to knock on Ahad's heart.

"I'll bring her over right away," Ahad replied quickly, quickly getting up and leaving the meeting room.

“Hahahahaha…” Irisviel clutched her stomach and collapsed on the conference table. “This is the first time I’ve seen the Master act so timid…”

Not long after, Ahad returned to the conference room with a little girl.

"Dad, you're back!" When Illya saw Emiya Kiritsugu, she trotted straight into his arms, an innocent smile on her face. "I missed you so much. The weather was finally sunny outside a few days ago, but no one took Illya out to play. It was so boring."

"Then daddy will take you out to play next time, and we will continue to look for walnut sprouts, okay?" A rare warm smile appeared on Kiritsugu Emiya's stiff face. He gently stroked Illya's hair and communicated with her softly.

"Is that Illya?" Newton couldn't help but smile. "She wasn't born according to the normal android production process, but rather, after ten months of gestation, she's the Einzbern family's child."

"That's the highest-level android we, the Einzberns, have amassed with all our technology." Ahad straightened his back slightly, a hint of pride in his tone. "She can be said to be our greatest masterpiece."

"Really? But I think she's just a child who misses her parents." Newton shook his head, stood up and walked to Illya, his eyes gentle and complicated. "Can grandpa hug you, Illya?"

"Eh--? But you don't look older than dad. It would be weird to call you grandpa, right?" Illya blinked. Although she was a little confused, she still stretched out her arms to Newton without any defense.

Newton carefully lifted Illya. Although he understood her condition the moment he saw her, he was still shocked by her incredibly light weight. She was only eight years old, yet she weighed less than fifteen kilograms. Had the Einzberns' supposedly state-of-the-art technology not improved at all?

He gently rocked Illya, his gaze softening unconsciously. "What do you plan to do with this child?" Newton turned and asked Ahad.

Ahad was silent. He could tell that Newton was quite fond of this child, but the child's function had been determined before he was born.

——She was destined to be a homunculus as a vessel of the Holy Grail. The magic circuits throughout her body were transformed to form the Holy Grail, and her heart in particular was transformed into the core of the Holy Grail.

"We...are planning to...um..." Ahad hesitated for a long time before finally speaking, "We plan to make her the person in charge of future Holy Grail War matters."

There is nothing wrong with what he said, Ahad is quite good at speaking.

A complicated look flashed in Newton's eyes. He gently stroked Illya's back and felt her weak heartbeat.

"Really?" Newton sighed. "But this child is different from you."

"She's not the same as us. She can't experience happiness from this almost ascetic pursuit." Newton turned around and asked Illya in his arms, "Illya, tell me, what do you want to do in the future?"

"I want to be with Mom and Dad. I want to go out and play every day. It's so boring in the castle..."

"If you still intend to pursue your wish through the Holy Grail War, you won't have to rely on Fuyuki's Greater Grail anymore," Newton said. "Stop imposing your wishes on young people."

Newton gestured for Emiya Kiritsugu to open his carry-on suitcase. The lock clicked gently, and the suitcase swung open, revealing an enormous emerald green crystal. The crystal glowed faintly in the candlelight, and its transparent emerald interior seemed to be filled with tiny bubbles and flowing liquid.

"Fuyuki's Holy Grail has been contaminated, and you didn't react at all. Are you trying to make me laugh by using such an unstable thing to conduct experiments?" Newton said sarcastically.

Ahad's gaze was drawn to the crystal, and he seemed a little confused. "What is this...?"

"You really didn't notice the dirt inside the Greater Holy Grail, did you?" Newton explained coldly. "Although it's filthy, it's not bad for material." He put Illya down from her arms and gestured for her and Irisviel to leave the meeting room together. Illya glanced at her father reluctantly, then followed Irisviel out.

Newton continued, "I took it out and used it as material to make these philosopher's stones."

This Philosopher's Stone was about the size of a suitcase. Its emerald green crystal surface was as smooth as a mirror, reflecting the surrounding light and emitting a captivating glow. Upon closer inspection, intricate runes and formations could be seen within, as if the entire crystal were a vast and sophisticated magical circuit.

"I told you before, I'll give you something, and that's this," Newton explained. "It can be divided into several parts, each of which is enough to support a Holy Grail War."

He gently stroked the surface of the crystal, his voice tinged with pride and contempt. "A single Philosopher's Stone needs a year of recharge to store enough magical power to sustain a single Holy Grail War. It doesn't require spiritual veins; simply set aside, it will generate magical power on its own." Newton scoffed. "How dare you call the so-called Holy Grail the Crystal of the Third Law—"

"—This is the product of the third law, do you understand?"

"But I acknowledge your path," Newton said, "and that is my gift to you."

I'm sorry, I'm quite busy lately because I'm preparing for the postgraduate entrance exam, so I can't update more. I don't like to post too much nonsense, so I can only try to write more every day.

This chapter has concluded the story of the Fuyuki Holy Grail War. It is expected that this volume will end after Newton explains some things in the next chapter.

The above, please give me your feedback and suggestions. If there is anything wrong, I will try my best to correct it...

I'm recommending this book. It looks like it's a Mygo harem fanfiction, with the male lead? It's doing much better than me, with 7,000 readers before it even hits the shelves.

Comet Dragon, Breaking into the Gravity Field!

Volume 65: Alchemy Apprentice from the Fourth War: 2024. The Promise to

Deep within the Einzbern Castle, Xing Qingfeng sat alone in a spacious, ancient library. The harsh winter chill made the castle exceptionally silent, with only the occasional crackling of wood in the fireplace to accompany his thoughts. The library's walls were dominated by towering bookshelves, filled with dusty tomes that bore witness to the long history of the Einzbern family.

The outside world was covered in thick snow, a pure white, a stark contrast to the dim candlelight inside the castle. There were no electric lights in the library, only candles for lighting. Although the atmosphere was quite good, it was like some magical library in fantasy.

But this made Xing Qingyu quite uncomfortable, as he was not used to reading by candlelight. In the past, when there was a power outage at university, his roommate would light a candle and sit in the dark while he fell asleep.

Xing Qingqi didn't close the window completely, but left it a crack to let the cold air in, to clear his mind. Snowflakes drifted in through the narrow window, landing on Xing Qingqi's shoulders, then quickly melted into water droplets in the warmth of the room, disappearing silently on the intricately patterned carpet.

"Damn, being human is so hard." Xing Qingyu rubbed his dry eyes from reading for so long in the dim candlelight. He had mentioned wanting to reduce his sensitivity or eliminate these minor life problems, but Newton flatly refused.

"If you are asked to live a completely inhuman life, it will probably be a constraint for you." Newton said this, but Xing Qingfu simply thought that he was just talking without any consideration.

Xing Qingfeng's gaze returned to the Philosopher's Stone before him. In the dim candlelight, the small emerald green cube faintly shimmered with light. He carefully stroked the surface of the Philosopher's Stone, but could not sense any strong magical fluctuations.

Newton had once taught Xing Qingjiu that if an alchemical product constantly emitted its magical fluctuations, it could only indicate a design failure, demonstrating the inferiority of its internal and external isolation and packaging technology. Large amounts of magic power escaping meant extremely low magic power utilization, with a significant portion of the magic power not being effectively utilized and instead being converted into waste energy.
