Alchemy Principles of Type-Moon World

"With this, the difference between Western magic and alchemy is clear." Xing Qingfeng smiled slightly, his expression gradually softening. "I hope you will pay more attention to this in your future studies and not apply traditional Western magic concepts to our course."

The classroom remained silent, with only the gentle sound of air flowing. This moment of silence was broken by a slightly dissatisfied rebuttal.

"But teacher, the purpose of studying the Way of Magic is to reach its root." A student sitting in the corner stood up, his brow furrowed, and his tone was filled with anxiety. "If it's not to pursue the ultimate truth and reach the mysterious end, then what is the point of practicing the Way of Magic?"

Xing Qingyu's expression froze for a moment, but he didn't respond immediately. Instead, he quietly looked at the student, his gaze deep and penetrating through the slightly wrinkled corners of his eyes. He stood up straight, as if preparing to give a more composed answer.

"To live better, to make others live better, and to change the world." Xing Qingyu's tone suddenly became extremely solemn. He did not avoid her gaze, but locked it directly into the student's eyes.

The atmosphere in the classroom suddenly fell silent, and the students' eyes turned to Xing Qingyu. There was an oppressive silence in the air, and even the occasional breeze outside seemed to have become quiet.

"This..." The student opened his mouth, as if wanting to continue to refute, but he had no words to say. His voice died in silence, and his eyes were a little confused.

Xing Qingyu smiled softly, relaxing a little of the seriousness on his face. "Don't mind it, it's just an elective course. I don't force you to accept my philosophy." He waved his hand slightly, dispelling the tense atmosphere. "It's just that as the first class, I need to tell you who I am and what I want to teach—"

"--If you really can't accept it, I won't say anything more if you don't come to the next class, and I will still give you credits." These words immediately eased the heaviness in the air.

Just then, the clear bell for the end of get out of class rang from outside the classroom door, loud and rhythmic. Xing Qingyu lowered his head slightly, sorted out his handouts, and then said softly:

"That's all for today's class, everyone. I hope to see you next time."

Students began to rise, the classroom filled with the cacophony of footsteps and the clatter of chairs scraping across the floor. Xing Qingqu remained poised at the podium, his expression unwavering as he watched each student leave. He didn't rush to leave; he simply stood there, adjusting his stance slightly, his right hand resting lightly on the edge of the desk, seemingly lost in thought, quietly waiting for the last student to exit.

When the chaotic noise in the classroom finally died down and the door gently closed, Xing Qingqi finally breathed a sigh of relief. His brow furrowed slightly, and the confident and casual expression on his face instantly collapsed. He couldn't help but sigh. "Oh, why are there only four of us?" he muttered to himself, his voice somewhat helpless. "When we had the open class, everyone was talking so enthusiastically. How come there are only these few?"

Xing Qingqiu leaned against the podium, his thoughts racing. "It's not a good idea to rush into instilling other ideas in them. Rushing might just provoke rebellion..." He shook his head slightly, his lips curled up slightly in a self-deprecating smile. "But with just four of us, I still need to teach them some practical applications ahead of time, and then see what the standards of the Clock Tower's degree system are—"

"But the most important thing is to find a way to retain these four students and turn this elective into their major." Xing Qingqiu continued to think, planning the next steps. "After leaving my mark on them, I'll find a way to get their degrees as high as possible and their reputations as high as possible, just like the students who get a certain score in the exam that are advertised in tutoring classes..."

Xing Qingyu stood up straight, straightened his sleeves, and began to put away the handouts and notebooks on the table.

"Well, let's just leave it that way for now," Xing Qingfeng murmured softly, his frown gradually relaxing as his plan slowly came into focus. He took one last look at the classroom and turned to leave.

However, when he stepped out of the door, his steps suddenly stopped. He turned around and looked at the empty classroom again.

"——One day, I will fill this place up."

Is this frequency of interaction with students appropriate? However, the subsequent classroom sessions will not be described too much, and if they appear again, they will only emphasize the collision of some background settings from another perspective and the collision of ideas with students.

Volume 7: Xing Qingfeng's Perfect Arithmetic Classroom: . End of Semester

"At this point, we can conclude that the role of mercury in the elixir is to make the magic power it carries express specific properties and to promote further transmutation of other substances in the elixir." Xing Qingqiu's voice was steady and deep. As he spoke, he skillfully wrote words on the blackboard with chalk.

The light in the classroom was a little dim. A few rays of sunlight came in from the window and slanted down on Xing Qingyu's body. The wind outside the window gently blew the leaves of the trees. The classroom was quiet, with only Xing Qingyu's clear voice and the sound of chalk rubbing lightly on the blackboard.

"But," Xing Qingfeng paused, "is mercury itself really necessary? This deserves a question mark." He paused, drew a large question mark on the blackboard, then slowly turned around, his gaze sweeping over the students. "Many elixirs simply cannot further couple with magic power without mercury."

Suddenly, a student's voice broke the silence: "Teacher, is this an unverified theory?"

"Whether mercury itself plays a direct role in the elixir still needs experimental verification." Xing Qingfu turned his gaze from the students back to the blackboard. He paused, his brows slightly relaxed, his tone still gentle. "But I have verified that mercury changes the nature of magic power. The specific verification process is difficult for you to understand even if I write it out, so I will explain it in detail after next school year."

"No, I mean, uh..." The student paused, glanced at the other students, and whispered, "If you just leave your unfinished project out like this, it's easy for others to..."

His words paused in mid-sentence, as if the air itself had frozen. The other students in the classroom also stopped what they were doing and turned their gazes towards the speaker.

Xing Qingwu raised his eyebrows slightly and gently took over the sentence: "Being proven first and then patented?"

The student breathed a sigh of relief after hearing this and nodded with a hint of apology on his face. "Yes, yes, especially those poor fellows who have no money." He lowered his eyes unconsciously as he spoke. "They don't have the resources to further their magecraft research, and using other people's patents is simply unaffordable for them—"

"—Their abilities aren't enough to ignore these conditions and achieve breakthroughs," the student seemed increasingly confident. "So they resort to many despicable things. They deliberately inquire about other people's academic achievements, attempt to plagiarize them, and preemptively register them in order to profit from them."

"Teacher, the knowledge you've taught this semester is very useful," the student hesitated, then whispered, "but it involves too many of your personal research directions." His words were filled with concern and anxiety. "Many of them are even theories that can produce results very quickly. It only takes a little time to conduct specific verification before you can apply for a patent..."

"Ah, it's okay," Xing Qingqi smiled slightly. He waved his hand, indicating that the students didn't need to worry too much. "I don't care about these-"

"—I'm glad he can help me share some of the pressure," Xing Qingfeng narrowed his eyes slightly, glancing past the students into the distance, as if planning something. "If he really wants to steal my work without using my name, then I can just kill him directly."

The classroom fell silent for a moment, and the students seemed to hold their breath for a moment. The student, clearly not expecting Xing Qingqi's response, froze in silence, his mouth half-open, unsure how to respond.

Xing Qingyu smiled slightly. He stood behind the podium, his hands resting lightly on it. He shook his head slightly, raised a finger, and pointed at the ceiling:

"Please," Xing Qingfeng said confidently, "My teacher is Isaac Newton."

Xing Qingfeng continued lecturing. He pointed to the densely packed rows of formulas and symbols on the blackboard, urging the students to pay attention.

"Of course, if you have this idea," his tone suddenly became slightly teasing, with a light reminder, "you can try to design an experiment to verify this theory during the holidays. I have actually given you the specific ideas -"

He paused, his eyes slowly scanning the students sitting in the classroom, deep in thought.

"—Remember the emergency treatment method for mercury I demonstrated to everyone during the open class?" Xing Qingfeng continued, his eyes flickering slightly. "You can try injecting a small amount of mercury-containing elixir into a mouse and using magic to mark the path of the mercury in the elixir within the mouse's body."

At that moment, the bell suddenly rang, its crisp sound shattering the momentary silence. Xing Qingqiu was slightly startled, then glanced up at the clock hanging in the corner of the classroom, seeing that the time was exactly at the end. He gently tapped the notebook on the podium and looked around. "This is the end of the last class of this semester." His voice remained steady and confident. "I won't give you any summer homework. After all, I'm not sure if you will choose to come to this classroom next semester—"

"If you still choose to come to this classroom," Xing Qingqiu continued, "then this holiday, you can try to design an experiment on any topic." He glanced around the class, which of course consisted of only these four students. "Like that student just mentioned, I've raised many personal research directions in class, many of which are close to completion. You can choose any one and try to complete it."

The blackboard on the podium still reflected a faint light. A breeze outside the window gently rustled the curtains, bringing with it a hint of summer heat and the rustling of leaves. Xing Qingqiu stood firmly in front of the podium. He continued, "Of course, this isn't mandatory homework. Just treat it as holiday practice—"

Before he finished speaking, the atmosphere in the classroom finally relaxed. Students slowly stood up to collect their notes, and whispers gradually rose. Xing Qingyu looked at them with a smile, as if waiting for something.

"——Everyone, have a happy summer vacation."

----------------------

London's summers are never oppressive, but rather a bit chilly. After all, the highest temperature rarely breaks 25 degrees Celsius, and the average temperature stays around 15 degrees Celsius.

As a result, the streets are bustling with pedestrians, most of whom are dressed casually, with the outlines of trench coats visible. Groups of young men and women gather around the stalls next to the bar, and the greasy smell of hot fish and chips wafts on the breeze, almost intertwining with the exhaust fumes from double-decker buses.

A gentleman in a trench coat strolled slowly down the street, his shoulders swaying slightly. The women beside him, wrapped in colorful silk scarves, walked lightly but not hurriedly, their shoulders slightly hunched. Children wandered idly through the streets, noisily discussing their little secrets. Laughter and arguments mingled, echoing from far behind them.

The noise caused by these bustling figures gradually disappeared under the shadow of a red brick viaduct, and after entering Druid Street and inadvertently turning into a fork in the road, it completely stopped.

It's not a deliberately artificial barrier, but rather a barrier formed naturally by the city's layout and other factors. If this line of thought is further developed and combined with so-called numerology, perhaps we can tiptoe and touch the heel of the spiral hall's feng shui numerology.

——However, it is a pity that due to the characteristics of Western magic, they prefer closure and concealment, so their development direction is completely different. Naturally, they will not further follow this idea, but only stay at the most basic application.

I've strayed off topic. Anyway, a couple of steps further, you'll see a reddish-brown building. It's El-Melloi's property, over a century old. While London has many old buildings, few are older than this one. While it looks poorly maintained, El-Melloi had actually renovated it when Waver moved in.

As for why it looks like a dilapidated building, with cracks all over the reddish-brown brick walls and chimneys, but no maintenance was done during the renovation...

...Doesn't this prove that this is the territory of the old Union Jack?

Yes, this is where Waver usually lives. And at this moment, he happens to be at home—

——Sitting in front of the TV and playing video games with Xing Qingqiu.

After some renovations, the house had been transformed from a dilapidated apartment into a relatively grand flat. Several walls had been demolished to open up the space, but despite this, Weber had still managed to make this place, which should have been clean, spacious and bright, even more unbearable than a cheap apartment.

During the renovations, El-Melloi allocated funds and meticulously orchestrated the work. Back then, the house looked like it had just been built: new floors, pristine walls, exquisite curtains—nearly every detail exuded a blend of ancient and modern. Furniture was neatly arranged, exquisite paintings hung on the walls, and sunlight streamed in through the large windows, gently illuminating every corner with its warm glow. Back then, the house felt comfortable and elegant, like the retreat of a high-ranking magician, perfect for quiet contemplation, work, and life.

However, as time passed, especially after Weber moved in, this once neatly and elegantly renovated home now exhibited a shocking state of disarray. While still spacious, the atmosphere within had become heavy and cluttered, as if its original elegance had been obscured by the grime of time. The bookshelves were filled with disorderly stacks of books, and several thick volumes, piled high, tilted by the weight of the clutter. The pile of old items on the desk also seemed particularly out of place, with yellowed papers and documents scattered about, and even moldy bread crumbs piled in the corner, as if they hadn't had time to clean up.

The floor was littered with laundry, dirty clothes and coats discarded carelessly, some piled up like mountains. In a corner of the living room, a half-eaten pizza lay uneaten, its edges dried out and the box still stained with mold. It looked like it was left over from two weeks ago. A tangled smell hung in the air, the aroma of food intertwined with the odor of days-old debris, making it seem like I didn't want to stay any longer.

But now, Weber and Xing Qingqi were still sitting on the large sofa, not caring about the mess around them.

Two PlayStation 2 game consoles were placed side by side in the corner of the TV cabinet, each connected to a different monitor. In front of the two TVs, they each sat, controlling the controller.

"No, you're fucking good, fucking good," Xing Qingfeng shouted while rubbing the controller. "Fuck, my brother's health is already like this and you're still good! Jiaoda, damn, you're so bad at playing White Mage, why don't you play Scholar?"

"Is it my fault that your health is in danger? Don't you see how much damage you've taken for nothing? Is this how you play the tank position?" Webber shouted from the side, his mouth full of words like "fxxk" and "sxxt". "You weren't cowardly when you should have been, but when you should have stepped up and taunted, you were as cowardly as a french fry that's been sitting out all night. Now you're so anxious?"

"Aminos!"

Yes, these two people are currently playing a new online game that was released in May 2002——

——Final Fantasy XI, or rather, FF11.

The two of them are exploring new areas, but unfortunately, their progress in the group dungeon doesn't seem to be going smoothly.

"Fuck it, let's take a break and come back." Xing Qingqi frowned, throwing the PS2 controller he was holding tightly in his hand with a sharp thud. He then turned around, picked up a slice of pizza, and stuffed it into his mouth without hesitation. The pizza's crust was slightly crispy around the edges, and the texture was a bit hard, but that didn't seem to affect his enjoyment of the taste. He took a gentle bite, his mouth opening and closing to make a few satisfying chewing sounds.

"Let's check the guide later. I'm confused..." Weber lazily took a sip from the Coke bottle beside him. After a moment's silence, he continued, "Let's stop here for today. I'm tired."

"That's all?" Xing Qingfan replied with a slightly dissatisfied tone, raising an eyebrow while chewing his pizza. "Then we'll have a wild party later."

"Ah...right," Weber suddenly seemed to think of something. He paused for a moment and turned to Xing Qingjiu with a slightly serious expression on his face. "I'm planning to go to Wales soon. Mr. Xing, if you're free, could you come with me?"

Xing Qingwu paused, his eyes wandering across the screen, then he looked up at Weber, "Ah? What are you going to do?"

"Won't the Fuyuki Holy Grail War begin in two years?" Waver sighed with a hint of emotion. "My personal abilities are truly limited, so I need a helper to assist me..."

Xing Qingyu's eyes lit up slightly, and the corners of his mouth curled up in a thoughtful arc. Then he yawned and leaned lazily on the sofa.

"Then you won't be done with me," he said, waving his hand casually, "it's just right that I'm going to go back and take a look."

Waver was silent for a moment, lowering his head and rubbing his temples. "Other Holy Grail Wars are fine, but the Holy Grail War fought by the most primitive Greater Holy Grail in Fuyuki is unique." He paused, took a deep breath, and looked up at Xing Qingqi. "I will participate in it on my own no matter what—"

"—Whether I'm borrowing El-Melloi's or yours, I'm ultimately relying on my former adversary." Waver lowered his head slightly, as if struggling with something. "He won't approve of this."

Xing Qingyu's expression turned more serious. He nodded, "Is that so..." He pondered for a moment, "So you're planning to develop your own power."

Weber looked at Xing Qingjiu, his eyes filled with a hint of helplessness and determination. "Yes, but after all, the place we're going to is a bit unfamiliar, and you happen to have time, so just to be on the safe side..."

But I refuse!" Xing Qingyu rejected Weber's request without hesitation.

"Huh...?" Weber was stunned. He obviously didn't expect that his carefully prepared request would be rejected so bluntly.

Xing Qingyu didn't give him a chance to say anything more. While biting his pizza, he continued, "Bro, we've known each other for almost ten years." He made a slight chewing sound in his mouth, his face expressionless, but his eyes were slightly narrowed.

"Even though I often send you all sorts of messed-up missions with Kenneth, and you insist on calling me by some honorific, but when it comes down to it, don't hide your little secrets from me—"

Weber's face flushed slightly, and he felt a little flustered. His clever plan seemed to be starting to unravel. He rubbed the back of his head awkwardly, trying to regain some composure, but he clearly felt that he had little room to hide in front of Xing Qingjiu.

"—Wales is still in the UK. Given your personality, you've probably already negotiated with the destination, so there's basically no danger." Xing Qingfeng waved his hand, his tone relaxed. He continued, "And from what I understand, Lanis has been working overtime recently to complete the necessary preparations and work ahead of time. It seems she's learned something at the last minute."

Weber was stunned for a moment, feeling completely seen through. He bit his lip, gave a dry laugh, and tried to change the subject, but it was clear that he could no longer conceal his feelings.

"You're afraid of being alone with Lanis, so you've got to drag me along, right?" Xing Qingfeng shook his head slightly, his gaze like a sharp blade, dissecting Weber's thoughts inch by inch. "I won't be a light bulb."

"I hope you can save me, sir!" Seeing his plan exposed, Waver's usual calm and composed demeanor completely collapsed. His expression instantly became extremely anxious, even a little out of control. He stood up frantically, his face tense. "She, she, she, she..."

"She's still a minor, remember to control yourself." Xing Qingyu didn't seem to be moved. After he finished speaking, he lowered his head nonchalantly, picked up a piece of pizza, and continued to eat nonchalantly, "It's time to go, buddy."

"If I go with her alone, I'm afraid my stomach will ache like hell!" A trace of despair flashed in Weber's eyes. He even rushed over without caring about his image, grabbed Xing Qingqi's ankle and hugged her tightly. "Please, for the sake of my stomach and my hard-earned vacation, you have to come with me! If you're here, she can restrain herself a little. Without you, she's practically putting a pet collar around my neck!"

Xing Qingfeng glanced back at Weber, a helpless smile playing on his lips. "It's pretty good, isn't it?" He dragged Weber's body with ease and said casually, "As for the fun of it, those who understand will understand."

"Please, I'll do anything!" Weber's voice was full of anxiety, almost pleading. He grabbed Xing Qingqi's trouser legs tightly, his eyes full of despair, as if this last ray of hope was about to disappear.

Xing Qingyu suddenly stopped, turned around, and looked fixedly at Weber who was lying on the ground.

"You just said... you can do anything, right?"

"No...any request that's not too excessive is fine..." Weber swallowed, looking a little guilty. He knew that he might have fallen into a bottomless pit, but at this moment, he had no choice but to try his luck.

Xing Qingyu sighed softly, his eyes still showing a hint of leisure, "First of all, I have something to do these two days and can't play the game..." He said slowly, staring at Weber, as if enjoying his embarrassment and helplessness at the moment.

"I'll take care of your daily weekly group missions from now on!" Weber responded almost subconsciously.

"Then, the lesson plan for next semester is a bit of a headache..." Xing Qingyu continued slowly.

"I'll write it for you!" Weber answered without hesitation, his eyes almost flashing with the desire to survive.

"Also...if there are more students by then, not all of them may be suitable for me..." Xing Qingyu continued to put forward his request, his tone was lazy, but he seemed calm.

"I'll teach you!" Weber answered directly as if it were a conditioned reflex.

"Okay!" Xing Qingyu suddenly grabbed Weber and pulled him up from the ground, his smile deepening.

"I've been waiting for your words!"

At this moment, Weber still didn't understand what a horrible thing he had agreed to.

--------

I was looking up what games were popular in 2002. After much thought, and considering that Weber prefers Japanese games, I chose FF11. As I was writing, I couldn't hold back any longer.

That’s about it. Simple teaching and the like is rather boring, so I will follow the original work a little and open some small side quests.

Volume 8: Xing Qingfeng's Perfect Arithmetic Classroom: . Arriving at Wilson

Finally putting the last document down, Lanis rubbed her slightly sore wrist and sighed softly. She looked up at the French window beside her desk. The sky outside had darkened, and the lights of the clock tower dotted the deep blue sky, faintly outlining the unique contours of this magician's gathering place. A crystal chandelier in the study emitted a soft glow, casting light on the documents scattered across the desk, highlighting the girl's slender fingertips and delicate features.

While most day-to-day tasks could be delegated to El-Melloi's subordinates, as the actual head of the family's operations, she still needed to personally handle some core matters. As for today's workload, it was actually more than usual, as she was preparing for the upcoming week's schedule.

But—” She raised her chin, a subtle smile playing at the corner of her mouth, “it doesn’t matter.”

She had noticed a "special arrangement" in Weber's schedule a few days ago: a whole week of vacancy, with the reason stated as "handling personal business."

This discovery ignited a little excitement in her heart. After all, as the deputy trusted by her brother, Weber has always been more serious and responsible than Lanis had imagined. In addition, Lanis herself has been constantly throwing difficult problems to Weber, which has resulted in him always being in a state of severe stomachache. This kind of thing rarely happens.

This kind of private time specially set aside is really too interesting.
