Alchemy Principles of Type-Moon World

Then, he turned around quickly, his body swung as fast as lightning, facing Flatt accurately, and the chalk in his hand shot out like a sharp arrow, hitting Flatt's right shoulder blade accurately.

That was the key point in the magic circuit Xing Qingjiu had calculated. Normally, this strike would be enough to disrupt Flat's magic, temporarily causing his magic to spiral out of control.

Xing Qingfeng's control of force was excellent, thanks to the selfless dedication of the West Coast necromancer and the old magician in South America. It was precisely because of their willingness to serve as cadaver teachers that Xing Qingfeng had accumulated so much experience, just like his driving skills had become so perfect that he could knock people unconscious without killing them.

——The range of the out-of-control magic will not harm Flat's body, but it will make him feel very painful.

"Ah ...

"Order... Order to punish me—" Flatt struggled, his voice trembling a little. He seemed to want to say something, but the magic power raging in his body interfered with his words and he couldn't even finish them.

"How many times has this happened?" the girl sitting in the back row asked, supporting her cheek with her hands.

"Flat exploded three times last class, and at the end of the get out of class, Teacher Xing dragged him out to run thirty laps," the girl next to him thought for a moment and responded, "But Flat looked so handsome with his clothes soaked with sweat..."

"Alas, there's no hope for such a face-obsessed person," the girl next to him retorted, "I think Mr. Xing's calm and mature attitude is even more appealing. Oh my god, interrupting the recitation with just a piece of chalk is so cool..."

"It looks too mature for my taste."

"Just reflect on your actions right there," Xing Qingfu said coldly, pulling out another piece of chalk from his chalk box. "Where were we just now? Oh, yes," he paused, then turned back to continue his explanation. "...From this we can draw several conclusions. Magic itself also releases some energy, or magic power. This magic power is redundant and not fully utilized. We can tentatively call it the magic power utilization rate..."

Just as he was talking about "magic utilization rate", Flatt suddenly roared:

“—My magic didn’t stop, and it got out of control, ahh ...

The shout rang out almost simultaneously with the formation of the fireball.

Almost instantly, a dazzling burst of light erupted from an open area behind the classroom. A massive fireball instantly condensed and formed, hovering in the air above the classroom. It emitted an intense heat wave and brilliant light, instantly distorting the air and causing the temperature in the classroom to rise dramatically.

The fireball formed incredibly quickly. Upon closer inspection, it didn't appear out of thin air. Instead, it first summoned water, then used magic to electrolyze it, releasing hydrogen and oxygen. These gases were then compressed under intense pressure, and finally ignited, rapidly forming a fireball powerful enough to threaten the entire classroom. Although Flat's magic was chaotic and he didn't fully understand the underlying principles, he relied on his intuition for chaos magic to complete this chain of events.

Xing Qing turned around and saw——

The fireball filled nearly half the classroom. The blazing flames roared like a storm, distorting the surrounding air. The turbulent currents rushed in like a gust of wind, burning with such intensity that it was almost impossible to breathe. The violent magic power within the fireball formed visible waves, with flickering arcs of electricity traversing them. The color of the flames gradually shifted from deep red to orange-yellow, finally turning nearly white. It was as if the entire space was ablaze, poised to erupt with unimaginable power at any moment.

However, Xing Qingjiu's expression didn't show any panic or alarm, but rather a hint of surprise. He was a little surprised that Flatt's magic far exceeded his expectations.

The magic circuit he had precisely calculated should have triggered a loss of control and interrupted the magic, yet Flatt still managed to complete such a relatively complex magic trick. Even after Xing Qingfeng broke through the key node, Flatt was still able to maintain the integrity of the magic...

"...It's really troublesome." Xing Qingwu sighed.

If the troublemaker in this class was a mediocre person, things might be much simpler.

But this exceptional talent was a problem for Xing Qingqiu. If he were dealing with a bored, ordinary student, he might have been able to handle it easily, but how to better guide a student like Flatt, who was full of potential and impulse, was Xing Qingqiu's biggest headache.

Xing Qingfeng narrowed his eyes. He slowly extended his hand, palm downward, and stared expressionlessly at the oncoming fireball. The temperature in the air continued to soar, even causing the walls of the classroom to tremble slightly, as if compressing the entire classroom into a giant furnace.

Xing Qingjiu's movements were not hurried. He moved his fingertips lightly, and a light blue light instantly wrapped around his palm. Then, the light wrapped around the fireball, and the hot fireball suddenly began to shrink. The flame was compressed into an extremely condensed sphere, and the energy inside was constantly compressed and squeezed.

As the magic flowed, the fireball's brightness grew increasingly blinding, like a sun about to explode, its light illuminating the entire classroom. A sharp sound, like burning metal, filled the air. The surface of the fireball was no longer soft, but instead resembled a fire bursting with energy, compressed to its limit.

In the end, this huge fireball that could have blown up half of the classroom was controlled by Xing Qingqiu's magic power and compressed into a sphere the size of an apple, which was suspended in Xing Qingqiu's hand.

"Flat," Xing Qingqi's voice was calm and indifferent, "Do you want to play catch with me?" He raised his eyebrows, his tone seemed to contain a hint of sarcasm, but he was not in a hurry to exert any pressure.

Flatt's figure moved under the table. He climbed up tremblingly, barely supporting his body which was violently fluctuating due to the backlash of magic power. Then he raised his head and looked at the blazing sphere in Xing Qingqi's hand.

"——Teacher, I feel like I can't catch this ball in my current condition." He immediately got up and shouted with his hands raised high.

Xing Qingyu did not respond to him, but smiled slightly, with a hint of amusement in his eyes.

"Go on!" he said, and with a flick of his wrist, he threw the energy-filled fireball towards Flat like a projectile.

The entire movement was fluid and swift, the air in the classroom seemingly energized by the toss, and the fireball pierced the air, rapidly flying towards Flat. The fireball's energy was almost condensed to the limit. Even though it was only a small fireball that looked "apple-sized," Flat was quite clear about what Xing Qingfeng had done.

——This thing can blow him away, along with the dust and the classroom.

However, just when the energy ball containing enough energy to blow up the entire classroom was about to hit Flat, it suddenly dissipated into the air like bubbles in the sun, disappearing completely without a sound.

"You can't even control this much," Xing Qingfeng looked at Flatt, who was standing there motionless, with a look of disappointment in his eyes. "Just sit down and listen to the class. Hiss, where was I just now...?"

"As expected of Order Xing!" Flatt shouted loudly, his eyes full of admiration, "How amazing!"

Xing Qingqiu ignored Flatt's praise and remained focused on his explanation. "Yes, that's right. The utilization rate of magic power is a very crucial concept in magic. The source of magic power is usually obtained primarily from the 'small source' within our bodies. The capacity of each magician's 'small source' varies." He wrote slowly on the blackboard. "The most common 'small source' capacity is that of ordinary magicians, and the difference is not too great. However, in some extreme cases, such as individuals with extremely high small source capacity, their capacity can reach dozens of times that of ordinary magicians, or even more. However, such people are very rare."

Flatt was clearly not content with just listening. He raised his hand and asked loudly, "Teacher, as long as I have enough magic power, I don't need to worry about these things!" His voice was high, his eyes full of anticipation. "For example, how about replenishing my magic power through other means?"

"If you could accurately measure the difference between the magic you just cast and the magic I responded with," Xing Qingfeng replied while writing on the blackboard, "you would find that the total amount of magic power in the two is almost the same. I just condensed your magic. But the magic you just cast could only blow up my blackboard at most—"

"—and the fire blast I fired back was enough to flatten the entire classroom." Xing Qingyu turned around, his eyes fixed on Flatt. "Do you understand?"

He casually drew two spheres on the blackboard, one large and one small. "Look at that magic trick you just sent me. What effect do you want to achieve?"

"Probably trying to cause a big explosion." Flat answered seriously without hesitation.

"Very good." Xing Qingqi nodded and continued, "Recall the feeling of that fireball. Other students can also recall it. Did you clearly feel the release of light and heat, the dissipation of magic power just now?"

As soon as he finished speaking, the students in the audience nodded and agreed.

Xing Qingfeng took a leisurely look around and then asked, "So, is this light and heat useful?" He paused, his eyes shifting as if on a whim. "Is there anyone who can tell me the formula for the surface area of a sphere?"

There was a momentary silence in the audience.

Xing Qingfeng narrowed his eyes slightly in displeasure, scanning the silent students. "...? That's simple, right? The formula for the surface area of a sphere."

Finally, a student cautiously raised his hand, his voice uncertain: "Πr squared...?"

"..."

Xing Qingyu couldn't control himself and broke the chalk in his hand.

"That's... a very good answer. Actually, it's pretty close. But, classmate, that's the formula for the surface area of a circle. The formula for the surface area of a sphere is four times Πr squared," Xing Qingfeng forced himself to hold it together and wrote the surface area of the sphere on the blackboard. "It's easy to understand: the larger the surface area of a sphere, the more light and heat it emits, right?"

He paused. To help the students better understand, Xing Qingjiu recreated the magic trick Flatt had just performed. Suddenly, a powerful heat wave washed over them, as if the fireball had returned to the classroom, and the intense heat quickly filled the entire space.

"You should all be able to sense this," Xing Qingqi continued. "The longer the diameter of the ball, the larger it is, and the more magic power is wasted." He gently waved his hand, slowly compressing the magic power he had released. The fireball's volume gradually decreased, and its brightness grew dimmer. As the ball compressed, the heat release seemed to become less intense, and the surrounding temperature gradually returned to normal.

"Look," Xing Qingqi continued, "all that dissipated light and heat you're feeling is waste energy." He casually picked up a ball of energy compressed into a spiral shape by his own magic power and held it in front of the students. "That fireball just now utilized less than half of its magic power. With its size, the shockwave after the explosion wasn't concentrated, and practically all of its energy was dissipated. You can see that its energy was too dispersed to be focused on its target."

"Order Xing, I learned it!" Flatt shouted, "Isn't it?!"

Xing Qingyu turned around indifferently and saw Flatt excitedly expanding and contracting the fireball in his hand.

"..."

Xing Qingyu took a deep breath, raised his hand and patted the blackboard, making a crisp sound. The students instantly quieted down and all their eyes were focused on him.

"Anyway," Xing Qingyu turned around and glanced at every student. His tone was calm but with a hint of seriousness, "Just now, you students should have discovered a problem -"

He paused briefly, lowered his head to adjust the test paper in his hands, his eyes unconsciously scanning the students who were eagerly awaiting further instructions. He tapped the blackboard again, the sound emanating from the place where his palms collided. "To learn my course well, you must have a solid foundation in mathematics."

Xing Qingfeng continued without pausing, "—It's time for us to move on to the next stage of learning. We'll be adding two math classes per week." He scanned the classroom, as if assessing each student's response. "As for where to start..." He raised an eyebrow, the corners of his mouth curling up slightly, as if in a challenge. "It depends on how well you performed on this test."

As he spoke, he picked out a few test papers from the pile on the table and automatically distributed them to each student.

"...But," Xing Qingqi paused, his tone suddenly becoming more serious, "Flat." He turned around and glanced sharply at the blond boy who was still playing magic in his hands, "You'd better satisfy me in this exam-"

"——Otherwise, you will definitely not have a good life here with me from now on."

Flatt suddenly raised his head, his eyes flashing, the smile on the corner of his mouth did not disappear, but he looked even more excited.

"No problem, Order Xing!" He answered readily and confidently.

OK, it's about time to speed up the process and change the approach. I'm almost tired of simple lectures, so it's time to change the method. I will find ways to create more interesting stories from other aspects.

Volume 47: Xing Qingfeng's Perfect Arithmetic Classroom: . The Fallen Genius

Xing Qingqiu sat at his desk in the Clock Tower office, the dim light of the desk lamp illuminating the test paper in his hands. The air around him seemed filled with a tranquil atmosphere. The clock on the wall ticked, its hands moving silently in the dark room. The desk was cluttered with scattered, graded papers and a nearly used red pen.

Xing Qingqiu's gaze paused on the test paper, his brow furrowed, a look of melancholy written across his face. "Someone can still solve a linear equation. Good thing..." he muttered to himself, his eyes slightly weary. He slowly flipped open the paper, his fingers gently stroking the handwriting as his gaze wandered over it.

In these test papers, most students were able to solve the most basic four arithmetic operations smoothly. However, every time he saw these fragmented answers, he couldn't help feeling sad.

"It's a good thing someone can solve it..." He muttered to himself again, his mouth twitching slightly, as if trying to find some comfort. "But, are the questions I asked really that difficult?" He felt puzzled.

He sighed, pulled his hand back, and rubbed his temple. Every time he saw the students' answers, he felt a sense of powerlessness. These simple math problems, once taken for granted as fundamental knowledge, seemed like they were simply beyond the reach of these young people in the Clock Tower.

"I don't think the questions I gave are that difficult..." Xing Qingqiu muttered to himself again, his gaze fixed on a simple addition problem on the test paper. It was a basic exercise he'd assigned to his students, and one student had actually made an error. He drew a large red cross on it and wrote next to it, "Addition error, pay attention to details." While the error seemed insignificant, Xing Qingqiu knew that this fundamental mistake reflected a student's fuzzy understanding of the relationships between numbers.

However, the students on this test paper generally performed well. Xing Qingqi withdrew his gaze and turned to the next test paper.

This time, his frown deepened. This was a clearly poorly written test, riddled with calculation errors, including several errors in arithmetic operations. The student had even added the wrong number to a fraction, resulting in an answer far exceeding the actual result.

"You mean to say that this old lady who can't do magic usually walks at a speed of 200 meters per second while buying groceries?" Xing Qingfeng wrote something beside the groceries.

"Hiss, that's not right. It should be the difference in atmosphere. Is it my problem..." Xing Qingyu muttered in a low voice, "Education abroad doesn't seem to focus on mental arithmetic..." He tried to find a suitable explanation and pondered for a moment, but quickly rejected his idea.

The students' mistakes were not due to differences in the education system, but because their understanding of numbers was too weak.

"They're magicians, so there's always a need for practical application," Xing Qingfeng shook his head helplessly. "In this case, they really should be given more basic practice." He paused and continued his analysis. "It's not that they're not smart, they're just used to relying on the intuition of magic itself."

Another test paper was opened. Xing Qingqi scanned it and sighed softly, "That's not bad. If this is the case, they just neglected to practice the relationship between numbers." He put down his pen, closed his eyes, and took a deep breath to ease the melancholy that had been lingering in his heart. However, a new problem emerged -

——There were actually such huge differences in students’ mathematical foundations that he had to re-examine his teaching methods.

"It seems like students from aristocratic families have a better foundation..." He thought to himself, his eyes unconsciously scanning several test papers, noticing that the calculation steps on one of them were clear and almost error-free. Xing Qingqi's fingertips unconsciously tapped the table lightly, and he pondered for a moment, "Is it because of my family background—"

"-No, it seems that he did study on his own during the summer vacation. Very good." Xing Qingqiu glanced at the name on the test paper and nodded with satisfaction.

But then he flipped to another test paper, and what he saw made him frown again. This was another student from an aristocratic family, and his paper was riddled with errors, even simple addition and subtraction gone awry. Xing Qingqiu gathered all the aristocratic papers he had graded and pondered silently, "This is a bit like a diode," he sighed helplessly, "Being a student from an aristocratic family doesn't necessarily mean they have a better math foundation."

"In comparison, the level of the new generation of magicians from the Democratic faction isn't much different." Xing Qingqiu was silent for a moment, then gently put down the test paper in his hand. "The data sample is still too small, making it difficult to derive useful information. Sigh."

"This one... seriously, they haven't even mastered the basics, yet their attitude is excellent. You can tell they want to write something." Xing Qingqiu sighed again, his gaze lingering on the test paper of a seemingly lazy student. The handwriting on the paper was irregular, even a little sloppy. "You can tell they're really willing to learn, which is a good thing."

Xing Qingqiu opened the test papers again, analyzing the students' differences as he graded them. He gently put down his red pen and took a deep breath, his tired eyes becoming more and more obvious. He carefully graded each test paper, writing a brief note for each error, trying to help the students find room for improvement based on their mistakes.

"Forget it, I'll continue tomorrow," Xing Qingqiu muttered to himself. He stood up and walked to the window, gazing at the gradually darkening sky outside. The afterglow of the setting sun shone through the gaps in the curtains onto his shoulders, its warm glow relaxing him slightly. His eyes grew hazy, as if he were lost in thought again.

"Tomorrow... maybe it will be better." He murmured, turning back to sort out the test papers on the table. However, just as he was about to put his things away, a familiar test paper suddenly appeared in the pile of test papers in front of him.

That was Flatt's test paper.

"..." Xing Qingqiu was silent for a moment, then couldn't help stretching. He then sat back down at the table and picked up the test paper. His eyes grew cold, and an inexplicable anger rose in his heart.

"Flat..." Xing Qingqi's mouth corners slightly raised, and he silently recited the student's name, "You wait..." He looked at the handwriting on the test paper with gritted teeth, and a flash of anger appeared in his eyes.

There are absolutely no steps to solve the problem above, but Flatt is not like a so-called math genius who can give the answer intuitively without any process. Well, he is not that genius. In fact, his answers are always different from the correct answers.

In other words, it was all guesswork, and all the guesses were wrong.

However, what drove him crazy the most was the blank part of the test paper, which was filled with cartoons and a lot of praise for Xing Qingjiu.

Xing Qingyu took a deep breath and clenched the red pen in his hand tightly, almost breaking the pen.

"If I don't beat you to death, I won't be named Xing..."

————————————————————————

As class was about to begin, the clock's hands quietly approached the hour. The classroom was so quiet that one could almost hear each other's faint breathing. Sunlight slanted in through the window lattice, casting a few mottled shadows on the table and books.

Most of the students looked uneasy with flickering eyes.

A few people sitting by the window were even whispering about the test, occasionally frowning or looking down to calculate. Uncertainty and uneasiness had seeped into their bones, and an atmosphere of unease was quietly spreading. After all, no matter how much Xing Qingfeng emphasized that it was just a small test to assess students' basic skills, it still couldn't dispel the students' instinctive fear of the test and their grades.

——Especially when most of them know that they didn’t do well in the exam at all.

Yet, among this group of nervous students, Flatt stood out. He half-slumped back in his chair, one hand lazily resting on the back of his head, a confident smile playing on his lips. His smug expression made him seem like the best student in the class, completely unconcerned with anything going on.

"Of course the answer to this question is this," Flatt said loudly to the student next to him without hesitation, his voice particularly harsh in the quiet classroom. "Trust my intuition, intuition."

A student sitting next to him hesitated for a moment, then looked down at the scrap paper in front of him, which had the previous calculation process recorded on it. He tried hard to recall the problem and began to recalculate carefully. His face was full of hesitation.

"Did I calculate wrong?" He couldn't help but wonder. The other students also felt Flatt's confidence to some extent, and their inner uneasiness began to spread. It seemed that some of them began to doubt whether their previous answers were correct.

——Because no one in the whole classroom could match the answer that Flatt shouted out, and his genius performance impressed everyone in these classes.

Flatt didn't notice the change in the students' expressions, and continued to laugh triumphantly. "See, my intuition has never been wrong! Believe me, Order Xing will definitely give me a high score!"

"Flat Escaldes," Weber, who had just finished teaching, said from the classroom door. He was holding a heavy lesson plan and half of his body was leaning into the doorway. "Teacher Xing is calling you."

"Yes!" Flatt suddenly stood up from his seat, his voice high and filled with confidence and excitement. He turned around and raised his eyebrows at the students sitting around him, winking playfully. "You see, I must have done the best on the test, so Order Xing specifically called me over!"

He patted the shoulder of a classmate next to him vigorously, with an undisguised complacency on his face.

"I think it might be the other extreme..." a classmate next to him muttered.

"Haha, wait for my good news." Flatt didn't mind these words at all. As if he didn't hear them, he strode out of the classroom with confidence on his face, his footsteps light and rhythmic.

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

Flatt had just pushed open the office door when a chill came over his heart. His steps paused for a moment, and the sudden intuition made him almost want to step back immediately.

Even though he didn't have a keen sense of smell or the ability to directly sense danger, he could still keenly feel—
