Alchemy Principles of Type-Moon World

Flatt didn't have much math background; his actual math knowledge was only at the level of a junior high school student. Xing Qingfeng thought silently, although this fourth-order magic square wasn't difficult, it would still take someone at this level some time...

"...Order Xing, I've finished writing!" said Flatt.

"Hiss..." Xing Qingyu frowned slightly as he watched Flatt's movements. Flatt picked up the pen and, without hesitation, began filling in the numbers in the form, his movements swift and smooth. Xing Qingyu had expected Flatt to encounter some difficulty, but as he examined the results, he was stunned.

"Interesting..." Xing Qingqi muttered almost to himself. He reached out and picked up Flatt's answer from the table, examining it carefully. Four rows and four columns, two diagonals, the sum of all the numbers perfectly matched, and the filling order was flawless. It was a perfect solution, even exceeding Xing Qingqi's expectations.

"Tell me about your ideas?" Xing Qingyu put down the paper, his eyes filled with inquiry.

Flatt tilted his head and thought for a moment, his brow furrowed slightly. "I don't know, I can't really put it into words." He raised his eyes to look at Xing Qingjiu. "It's probably... the moment you told me how to do it, I saw the form and subconsciously knew how to fill it out—" He paused, as if recalling something.

"—The only uncomfortable thing is that I can't make too many changes."

Xing Qingqiu's brow furrowed slightly, and his fingers tapped lightly on the table. He was once again surprised by Flat's reaction and his intuition. It seemed that this intuition was indeed not limited to the magic path, but also manifested in other fields.

"Go on," Xing Qingfu handed him the next page of questions.

Flatt took the paper without hesitation, picked up his pen, and began filling in the numbers. Xing Qingqiu continued to watch him. Without a pause or delay, Flatt's pen danced across the paper like flowing water, barely a hint of hesitation. Xing Qingqiu noticed that Flatt didn't seem to be confused by the questions as before. In fact, his speed increased as he wrote, perhaps because he was familiar with the feeling.

Half a minute later, Flatt handed the paper to Xing Qingqi, his eyes gleaming with anticipation. He didn't say much, simply waiting quietly for Xing Qingqi's comments. Xing Qingqi lowered his head to check and found that the answer to this question was also perfect.

"Continue." Xing Qingfu said lightly, handing the next page of paper to Flat. This time, it was a sixth-order magic square.

As Flatt's movements quickened, his fingers darted across the paper, rapidly filling in the blank spaces with numbers. After finishing the sixth-order magic square, he didn't wait for Xing Qingqi to speak; he turned the page and began writing the next test.

Xing Qingyu watched Flatt fill in the blanks smoothly, from level six, level seven... until the ninth level was completed.

He finally stopped and hissed.

On the next page are five five-by-five magic squares.

"Order Xing, what does this mean?" Flatt suddenly stopped writing, a hint of confusion in his eyes. He pointed to three pictures on the next page and asked, "These three pictures are different from the previous ones."

Xing Qingqiu picked up a nearby Rubik's Cube, spun it around, and explained to Flatt, "These five pictures are five-by-five magic cubes, just like this Rubik's Cube." He gestured for Flatt to look at the three pictures and continued, "The five pictures in front of you are like the different layers of this Rubik's Cube. What you have to do this time is not just to satisfy the equality of the sums on a single page, but to combine them, imagine their relative positions, and then ensure that the sums on any straight line are equal."

Flatt's gaze finally paused. He looked down at the magic cube before him, his brow furrowed slightly, as if trying to process everything. But after a moment, he quickly put aside his hesitation and picked up his pen to continue filling in the blanks. His movements remained smooth, with almost no pause. Finally, he put down his pen, breathed a sigh of relief, and looked up at Xing Qingjiu, a smug smile on his face.

"It's done," Flatt stood up straight, stretched, and then looked at Xing Qing, the owner of Erling, and Lu Jiu. "The next page too?"

Xing Qingqi glanced at Flatt's answer, confirming it was correct. He then looked up at Flatt. A hint of impatience was already visible in Flatt's eyes, and his hands were unconsciously making small movements in the air: he tapped the table with his fingers and tapped his toes on the floor, clearly eager to finish this tedious task.

"Yes, but I don't think it's necessary." Xing Qingfu replied in a flat tone, "You can rest now, I'll change you into another set." After that, he stood up, walked to the drawer next to the bookshelf, and took out another set of materials.

"Order Xing is the best!" Flatt suddenly beamed like a child, dropping his pen and pacing excitedly around the office. His movements were a bit exaggerated, his arms flailing so wildly that he even accidentally bumped into the back of a nearby chair. Xing Qingwu watched him, shaking his head slightly, but a smile unconsciously curled up at the corner of his mouth.

"Is this wine?" Flatt's eyes suddenly fell on the wine cabinet. He was obviously interested in the bottles of wine in the wine cabinet. "Order Xing, is this what you occasionally drink during class?"

Xing Qingwu looked at the wine cabinet, where several bottles of wine and whiskey were quietly placed. He raised his eyebrows and replied, "No, it's usually Scotch whiskey." The tone of his voice rose slightly. "You want some?"

"Yes!" Flatt answered almost without hesitation, with a childish excitement flashing in his eyes. He took two steps towards the wine cabinet, as if thinking about whether he should open the bottle and taste it directly.

"Let's talk about it when you come of age," Xing Qingfeng shook his head, his tone filled with helplessness, "You little brat."

Flatt smiled disapprovingly, as if it didn't bother him at all. He turned and walked away, saying, "I've tried it before. It's a botanical brew, and it's really delicious."

"No one stopped us?" Xing Qingwu asked.

"The older sister from the Botany Department offered to give it to me!" Flatt replied, "but she seemed to have passed out first..."

"Tsk," Xing Qingqi raised his eyebrows slightly, his eyes sharpening slightly. "It won't work here anyway," he said with a slight reproach in his tone, "You're still a child, why are you drinking? Alcohol isn't something you should be consuming."

"Well, since Order Xing said so..." Flatt tilted his head, his tone seemed to be a little regretful and mischievous, "I originally wanted to try the plant family's craft brew with Order Xing again."

Xing Qingfeng glanced at him sideways, his face expressionless, his tone tinged with intimidation: "Do you think I'm someone who can be easily bribed? I'm just being nice to you and you're already thinking of tearing me apart—"

"——Come and continue testing, stop playing."

Flatt blinked, and suddenly seemed to realize something, revealing a playful smile.

"Oh, okay. I was wrong. How could Order Xing be easily seduced by such a trick?" Flatt smiled grudgingly, but his eyes were filled with mischief and helplessness. He saluted, his hands exaggeratedly swishing in the air. "Yes! Guaranteed FULL CLEAR!"

Xing Qingqi glanced at him calmly, his expression unchanged, as if he was accustomed to Flatt's teasing. He didn't respond, but simply flipped open the stack of papers on the table, pointed to the pattern on the previous page, and began to explain the next question concisely and clearly.

At this moment, the atmosphere in the office grew quiet. Sunlight streamed in through the blinds, casting a dappled light on Xing Qingjiu's desk. The air was filled with the faint scent of books and paper. The occasional sound of footsteps in the distant corridor and the rustling of branches outside the window added to the atmosphere of tranquility and concentration.

Xing Qingqi pointed to the picture of the church's rose window, his gaze fixed, and spoke succinctly, "Second question: This church rose window is made up of 128 rhombuses. How many colors are needed to ensure that adjacent rhombuses are different colors?" He paused briefly, as if observing Flatt's reaction, and continued, "You are not allowed to paint with a pen in advance. You are limited to..."

Flatt didn't wait for Xing Qingqi to finish explaining the problem. His eyes lit up with excitement, and he almost immediately realized it. "Four," he blurted out, his tone filled with a hint of ease and confidence, as if the problem was no problem at all.

Xing Qingyu raised his eyebrows slightly, his eyes flashing with a meaningful light, but he didn't say anything more, just nodded gently. "Okay," he said, then reached into the drawer and took out four brightly colored markers and placed them in front of Flatt. "Now color it, but there is one more request-"

Flatt looked up at Xing Qingjiu, his eyes full of anticipation, waiting for a new challenge.

"—After you finish coloring a square, the next square you color must not be adjacent to the previous one. There must be a gap between the two colored squares," Xing Qingfeng's voice remained calm and orderly. "And once you start coloring, you cannot stop."

"Got it!" Flatt said without hesitation, almost instantly understanding the idea as he took the four colorful pens. He grabbed a green pen and quickly began to color the first diamond. His movements were swift and precise, as if the entire diagram had already been drawn in his mind. With the first green stroke, he gradually filled in each subsequent square with color.

Xing Qingfeng sat behind the desk, watching Flatt's movements intently. Various lesson plans and test papers were still piled on his desk, but he didn't seem to be in a hurry to sort them out. Instead, he focused on observing Flatt's movements.

Xing Qingqiu's desk was piled with various documents, including his meticulously compiled teaching materials and the assignments and tests submitted by his students. He didn't rush to sort through them, not rushing to deal with daily affairs. At this moment, his attention was completely focused on Flat, but a question quietly emerged in his mind.

He suddenly felt a little worried that he might not be able to teach the child for too long.

Xing Qingqiu's gaze swept steadily over Flat's focused profile. Flat's talent was undoubtedly top-notch. Whether in his magical perception or mathematical reasoning, he displayed a talent far superior to that of ordinary people. It could even be said that Flat's talent surpassed Xing Qingqiu's own. Xing Qingqiu couldn't help but wonder if he should have realized this sooner.

Flatt's hand moved steadily back and forth across the paper, alternating between the red, blue, yellow, and green nibs, filling each diamond-shaped space. Flatt's face showed no sign of nervousness, but rather an expression of near excitement. His movements became faster and faster, and he didn't even need to pause to complete the next square.

Xing Qingyu would definitely not let go of such talents, because this classroom was established for this purpose, and Xing Qingyu was also quite confident that he would provide these followers with a better future.

——But what if Flat’s development speed exceeds Xing Qingjiu?

This worry left Xing Qingfeng somewhat bewildered. He wasn't afraid of his teaching methods being surpassed; instead, he worried that Flatt would miss out on valuable opportunities due to his rapid growth.

Although Xing Qingfeng was confident in the future, and he still believed that the future he brought would be far better than the present, it was ultimately just a "future." If Flatt broke through the existing framework early on, what Xing Qingfeng could offer him would probably be far from enough to support his lofty ideals.

He is just a child and there is no need for him to make concessions for Xing Qingjiu's future. This is a question that adults should think about.

Xing Qingqi raised his hand, touched his forehead, and slowly pondered the complex emotions in his heart. At this moment, Flatt's voice broke his meditation.

"Order Xing, I'm done!" Flatt's voice was filled with excitement and a hint of anticipation. He stood up from his seat and walked quickly towards Xing Qingjiu, his eyes sparkling, as if he was waiting for some kind of reward.

"Ah." Xing Qingqiu came back to his senses, momentarily taken aback, then lowered his head to carefully examine Flat's answer. His eyes swept across the paper, examining every detail, and finally he nodded. Flat's completion was almost flawless. The color combinations were not repetitive, and every requirement was met in an orderly manner.

"Are there other levels?" Flatt asked impatiently, his eyes almost shining.

Xing Qingyu sighed softly, feeling a mixture of relief and fatigue. "No more," he said. "As expected, you're quite talented."

"Oh! I knew it!" Flatt's excitement was beyond words, waving his hands in the air, "So I've passed the level!"

Xing Qingfeng pondered for a moment, his eyes still calm, "Hmm... maybe there will be a hidden boss."

Flatt was stunned, a flicker of surprise in his eyes, and then his smile became a little awkward, as if he suddenly felt a little embarrassed. "Well," he paused, his tone slightly hesitant, "since I've cleared the level, then..."

"...Can I have a reward, Order Xing?"

Xing Qingfeng raised his eyebrows slightly, put down the test paper in his hand, and smiled helplessly. "Ha, so that's what you were thinking." He shook his head and sighed softly, "What do you want?"

"I want to buy a GameCube (Nintendo's game console released in 2001)," Flatt's eyes lit up instantly, and he answered without hesitation, "but I don't have much money..."

"Ah, no problem," Xing Qingqiu scratched his head. Logically speaking, students who could study abroad in the Clock Tower should not worry about a mere game console. Even a new generation of magicians with no background could easily have wealth far exceeding that of ordinary people.

A huge grin instantly broke out on Flatland's face. "Great! Order Xing is the best!" He jumped up excitedly, dancing and cheering. "So when are we going to buy it?"

"Ah, there are some things to do later," Xing Qingfeng subconsciously glanced at the schedule, "You... should pack your luggage."

Flatt was stunned for a moment, seeming a little surprised.

"luggage?"

"Yes, hurry up and get ready." Xing Qingfeng's tone remained calm. "You have passed today's test. Next... let's go fight the hidden boss."

"Okay!" Flatt agreed without hesitation.

----------

Xing Qingyu's concern here is actually the reason why Flatt was kicked around like a ball in the original book. Of course, most teachers did not consider Flatt's future. They just had nothing to teach and Flatt's talents could easily offend them.

Xing Qingyu's thinking here also reflects this point. This little plot is also an opportunity for his teaching philosophy to gradually change.

Volume 52: Xing Qingjiu's Perfect Arithmetic Classroom: . Gin

The afternoon sun streamed into Xing Qingjiu's office through the high windows, the light gradually softening, and the air inside took on a hint of evening coolness. A single desk lamp remained unlit, and the books neatly arranged on the shelves exuded a woody fragrance in the warm light. The quiet in the air seemed oppressive, yet also comforting. Test papers, textbooks, and notebooks piled on the desk. Unsent emails flickered on the screen, and the occasional soft tapping echoed from the keyboard. In a corner of the office, an old-fashioned wine cabinet held several bottles of aged whiskey and wine of indeterminate age, leaving the air thick with the faint aroma of alcohol.

Xing Qingqiu sat at his desk, silent for a moment. His fingers gently touched the receiver of his phone, his eyes gazing into the distance through the light from the window. It was approaching dusk, and the streets outside were becoming less crowded. The occasional sound of car horns added a touch of movement to the quiet space. Xing Qingqiu sighed softly and answered the phone.

"Hello, senior? Yes, it's me, so can you help me contact him?" Xing Qingyu asked quickly after picking up the phone.

"Well, if you can contact someone in this area, that would be great..." Xing Qingqiu paused, frowning slightly, obviously thinking about how to express himself. "Ah? Can you contact that student? You guys are working together? Oh my God...Okay, okay, I'll leave it to you."

He listened to the voice on the other end of the line and nodded gently. Following his senior's reply, he expertly manipulated his computer keyboard, bringing up an email window on the screen. Xing Qingqiu continued typing, "Okay, I'll send you the test questions and answers for this kid today." He paused briefly, his eyes lowered as the words on the screen rapidly jumped out.

"This kid is truly incredibly talented," Xing Qingqiu said with unconcealed admiration, his fingers tapping away at the keyboard. "I've never seen such a gifted kid. He even managed to think for less than half a minute when faced with a fifth-order three-dimensional magic cube."

Xing Qingqi's eyes did not leave the screen. He quickly edited the content of the email, writing down Flatt's performance in as much detail as possible - but he restrained himself a little, fearing that excessive exaggeration would arouse the senior's suspicion.

"Okay, I'll send it to you right away."

Xing Qingqiu gently clicked the "Send" button. As the email flew off, he couldn't help but pause. His fingers lightly slid across the keyboard, confirming the content to ensure that no important details were missed.

The last line of text on the screen was exceptionally concise and clear, and Flatt's test results were clearly listed—almost flawless. His lips curled up slightly, revealing a faint smile, as if expressing emotion, yet also a hint of helplessness.

"That's it, I'll hang up first." He said in a low voice, looking away from the screen, gently pressed the hang-up button on the phone, then put the phone on the table, and his fingers easily released the receiver.

The other end of the line had fallen silent, yet Xing Qingqiu didn't rush to sort through the scattered documents. His gaze returned to the computer screen, a flickering presence. Flat's performance on the test replayed in his mind again. That almost effortless confidence and agility made Xing Qingqiu feel as if he were in another world. Flat's speed in completing each difficult problem was almost even faster than when he first encountered segmented thinking.

——He didn't even master the corresponding skills. His math level was only at the junior high school level, and he wasn't even an adult yet. You should know that when Xing Qingqiu was just getting started with segmented thinking, combined with high-speed thinking, his speed in processing these aspects was already at a level that ordinary people couldn't match.

And the senior he had met when he was studying at Trinity College was even able to surpass Xing Qingjiu at the time, or in other words, Xing Qingjiu Lily, in terms of talent alone.

Xing Qingqiu sighed. He stood up and turned to look out the window at the dusk. The scenery outside the window was gradually swallowed by the dusk. The gentle sunset shone into the room through the curtains, shining on the documents on the table, dyeing it with a layer of warm orange. Xing Qingqiu was no longer in a hurry to do anything. His eyes fell on the street in the distance. The street lights came on one after another. The evening breeze brought a little coolness, ruffling the curtains. London is always rainy. At this moment, the air is filled with the lingering warmth of summer, which complements the moist smell after a light rain, making people feel almost like they are in a dream.

The room was silent, the only sound being the gentle ticking of the wall clock. The teapot on the coffee table had long since cooled, the black tea no longer emitting its familiar aroma. The steam had long since dissipated, leaving only a thin layer of vapor on the surface of the liquid.

Xing Qingfeng glanced sideways. The wine he had specially poured earlier had also lost its original aroma, becoming almost bland and tasteless. The aroma of the wine in the air had long since disappeared after being exposed to the air for a long time.

He stood there quietly, as if waiting for something. Time seemed to freeze at this moment. Night gradually fell, and the light in the room gradually dimmed. Xing Qingqi lowered his head and sighed softly again. Finally, he withdrew his gaze and turned back to sit at his desk.

The desk was piled high with messy documents, test papers, and heavy books. Xing Qingqiu's desk was always overflowing with all sorts of information, piled up like a mountain, with even a small space difficult to find. Despite this, he didn't seem to be in a hurry to sort through the information, instead his eyes lingered on a special stack of test papers.

——Those were Flatt’s past class tests and exercises.

Xing Qingqiu's fingers gently pressed against the stack of papers, applying a slight pressure with the tips of his fingers. Flat's performance left Xing Qingqiu somewhat baffled. He gently flipped to the first page and reviewed the papers again in chronological order. His eyes followed the answers on the paper, and a slight frown crept into his brow.

"Strange." Xing Qingfeng muttered to himself, the doubt between his brows deepening. Although Flatt's accuracy gradually improved with time and practice, it was still obvious that this kid was more inclined to guess the answer casually.

——Or maybe it was the intuitive answer, but the problem was that his guesses were all wrong.

Xing Qingyu couldn't understand why Flatt could suddenly become a genius who could answer questions with just a blink of an eye, but he was sure Flatt didn't cheat.

——If Flatt wasn’t suddenly possessed by something, how could the manifestation of being possessed by a ghost be a sudden increase in his mathematical level?

Xing Qingqiu shook his head, putting aside these chaotic questions for the moment. He took a deep breath and refocused his attention on the task at hand. He sorted Flatt's test papers into a pile, then gently pressed the materials on the table to prevent them from scattering. After a moment, he turned and walked to the filing cabinet in the corner of the office. He gently opened the drawer and put the test papers one by one into the file bag.

He turned back to his desk and slowly sat down. His eyes swept across it, quickly sorting through the clutter of documents. There were not only unfinished lesson plans, but also drafts of his research project. To keep these questions from overwhelming him, he began to silently compartmentalize his thoughts. His mind silently divided them into separate parts, creating enough threads to start running independently.

While pondering his teaching schedule for the coming semesters, Xing Qingfeng had already quietly devoted part of his attention to his current research projects: optimizing deconstructive magic, studying pure spirits, and the relationship between the magic circuits of humans and even Warcraft.

——Oh, this is actually in the field of biology, or animal science. Thinking about this is purely because Xing Qing is addicted to cooking.

Each of these topics requires extremely high concentration, but for Xing Qingyu, his segmented thinking is mature enough to advance them in his mind simultaneously.

When different threads quarreled, Xing Qingqiu felt speechless.

He picked up the wine glass beside him. The aroma of the wine had long since dissipated, and the liquid was almost tasteless in the glass, but Xing Qingfeng still drank it down without hesitation. The wine slid down his throat, with a slight astringency, and instantly made his mind clearer.

The night deepened outside, starlight spilling onto the open space outside the window, and the light within the room gradually dimmed. Time slipped quietly, the hands of the clock on the wall moving silently, while Xing Qingqi's fingers continued to wander among the pile of teaching plans and projects. His thoughts, unmoved by the passage of time, deepened even more.

The scene outside the window gradually changed in the darkness. As time passed, the stillness of the night gradually retreated, ushering in the first rays of dawn. The rising light streamed in through the window, filtering through the gaps in the heavy curtains. The light, still somewhat soft, was enough to dispel the lingering gloom in the room.

Before he knew it, the light in the office grew brighter and fresher. Gradually, the clock's hands ticked towards the next morning, already ten o'clock. Xing Qingqiu's mind still wandered to his work, constantly calculating the projects and magic experiments for the coming weeks. Even so, as time passed, he paused for a moment, noticing the new email notification that suddenly popped up on his computer screen.

A gentle notification chime broke the silence in the room. Xing Qingqi quickly put down his pen and leaned closer to the computer screen. His eyes instantly locked onto the subject line and sender's address, a flicker of anticipation and excitement in his eyes.

That email was exactly the response he had been expecting last night. As he expected, the content of the email confirmed all the details and arrangements he had mentioned on the phone yesterday.

"Such high efficiency! I didn't expect you to be so reliable..." Xing Qingfeng sighed as he browsed the email with shining eyes. "Hmm... preferably in the next two days... then let's go now."

He stood up, stretched, and turned his gaze to the scene outside his office window. The light blue of the sky had been replaced by white clouds and golden sunlight. The morning light softly shone on the desk. His fingers began to sort through the documents almost without thinking. He casually lifted the suitcase he had prepared from the corner and took Flatt's test papers from the filing cabinet, placing these important materials into his bag.

——By the way, he placed the prepared overtime plan for Weber on the table and called Mo Fajia, asking her to hand over the plan to Weber when she came to the office to play.

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

The airport hall at noon was spacious and bright, with lights shining through the large glass windows onto the floor, casting long rays of light.

Xing Qingjiu and Flatt stood out in the crowd. Xing Qingjiu wore a long gray coat and carried a brown leather suitcase. Flatt, on the other hand, looked energetic, carrying a black suitcase in both hands. His hair was slightly tousled, its golden strands gleaming in the sunlight. He followed Xing Qingjiu and excitedly asked, "Order Xing, where are we going?"
