Alchemy Principles of Type-Moon World

"Of course, it's hard to make you understand just by talking," Xing Qingfeng said as he calmly removed his coat, revealing a white shirt. He rolled up his sleeves, revealing his slender arms and lean wrists. His movements were effortless and fluid, drawing the students' attention. "Next, I'll demonstrate a simple necromancy technique."

"To put it simply, all necromancy, no matter how complex or simple, must go through these steps—"

"—First, create an environment that can accommodate the existence of spirits," Xing Qingfeng explained. "Most necromancy techniques rely on existing environments, such as public cemeteries, and most of the time they must be transformed into spiritual places."

"If we were to artificially construct a temporary environment, it would require a great deal of effort. Otherwise, it would be much more difficult for the summoned spirit to interact with physical matter," Xing Qingqi continued. "Students in the Spirit Conjuration Department should have heard of your director's 'Mobile Spirit Tomb'. The greatest feature of this ritual is that it compresses the layout of the spirit environment into a very small portable space, and then accommodates as many spirits as possible within this space—"

"—As its name suggests, it's a portable spirit tomb environment. I won't go into the details of its special features, as everyone will understand."

"The different systems of necromancy, and the systems and rituals from different cultures, are almost a world apart." Xing Qingqi casually pinched a ball of magic power and rubbed it in his hands, changing its structure. "If we want to learn necromancy normally, we must go through these systems one by one and choose the one that suits us best. Of course, most magicians actually inherit the system from their family—"

"—But, isn't there a way for us to find a commonality among this vast sea of necromancy?"

As soon as he finished speaking, Xing Qingfeng loosened his grip, and the ball of magic in his hand suddenly exploded in the air. The magic in the air began to condense again, forming a standard spirit field. Unlike the oppressive and gloomy atmosphere of traditional necromancy, this spirit field was more like a pure flow of magic, transparent and full of flowing light.

All the students in the class were keenly aware of the change in the environment. Some students thought that this might be the environment that Xing Qingqi mentioned to accommodate spirits, but this environment did not have the eerie feeling that traditional spirit summoning gave people. On the contrary, it was quite pure, just a group of magical structures.

"This is the universal spirit environment I've constructed." Xing Qingqiu's voice remained steady. "It doesn't rely on the symbolism of a particular culture, but rather is based on the commonalities of all spirit summoning techniques. Is there anyone willing to come up and try to directly summon a spirit?"

After a few seconds of silence, many students tried to raise their hands, and Xing Qingwu picked three at random.

"Just treat this place as the environment of a spirit tomb, skip the steps of building the environment, and use the medium to summon directly," Xing Qingyu said to the first student.

After the three students used spirit summoning techniques from different cultural systems and successfully made the spirit exist stably and easily interfere with matter, Xing Qingjiu released the spirit field, and the summoned spirit became unstable and eventually dissipated into the air.

"So, this is what I will teach you." Xing Qingqiu continued, his voice clear and calm, as if the summoning scene just now was just a passing cloud. "This class is just showing you one direction. In the next seven open classes, I will show you the other directions and give you the simplest explanations-"

"——And for the next period of time, I hope everyone can take a simple pop test."

"The above content is essential knowledge for further study, so please don't try to cheat. This will allow me to understand your average level so I can adjust my subsequent teaching."

With a gentle wave of his hand, almost every student could see him pull a stack of test papers from thin air. The papers seemed to be plucked from some nonexistent dimension, accompanied by a subtle shift of light and shadow. Xing Qingfeng didn't move much, and the papers fluttered down from the air, each sheet drifting like a feather, making almost no sound as it landed precisely in the hands of each student. Even the familiars were not spared, and they all snatched the papers from the air.

——It was a stack of advanced mathematics test papers, but they only involved the simplest linear algebra.

Volume 2: Xing Qingfeng's Perfect Arithmetic Classroom: . Voluntary Overtime

"The math literacy of the students at Clock Tower isn't generally very high..." Xing Qingqiu muttered, frowning as he examined the assignments handed in. Inside the office, the desks were cluttered with test papers and notebooks. Sunlight streamed in through the old glass windows, casting dappled shadows on the walls.

"How can I learn magic if I'm so bad at math?" Xing Qingfu muttered to himself as he continued to flip through the test paper in his hand.

At this moment, the office door was gently pushed open, and Kenneth appeared at the door, leaning lazily against the door frame.

"Isn't that perfect?" Kenneth said casually as he walked into the office and closed the door. "Currently, most of the students attending your open class are from the Modern Magic Department. As for those from the Minerals Department and the Spirituality Department..."

"They're actually here to support you out of my respect," he continued, sitting on the sofa in his office. "When you formally explain the content in depth later, most of them won't choose your class."

Xing Qingyu paused his movements and looked up, his eyes slightly puzzled. "Oh? Why do you say that?"

Kenneth leaned back in his chair, legs crossed, his golden hair casually draped over his shoulders. He said casually, "You don't quite understand the power structure of the Clock Tower and the distribution of magician factions." He paused, as if considering how to explain it more concisely. "Simply put, in the Mineral and Spiritual Departments, there are almost no civilian magicians without family backgrounds."

"The practice of magic in the Mineral Division relies on a large number of rare gemstones and mineral materials," Kenneth's fingers tapped lightly on the coffee table in front of the sofa. "And the practice of the Spiritual Division must rely on corresponding spiritual sites. Neither of these is accessible to ordinary magicians without family backgrounds." He paused, as if to emphasize something. "This is not just a question of resources, but more importantly, the solidification of power structures. In the Clock Tower, a magician's family and background often determine the magic and resources you can access."

"Furthermore, even if a magus family boasts a wealth of experience, once their fortunes fall, their attainments in the ways of magic will rapidly decline," Kenneth continued. "Imagine a magus specializing in minerals having to work for over ten or twenty years just to afford a single consumable gemstone for daily practice. Without other opportunities, it would be difficult for this magus to continue their studies in the ways of magic." He paused, his lips curled slightly. "This is their current situation."

"Thus, the Mineral and Spiritual Summoning Departments are completely controlled by the aristocracy," Kenneth continued, tapping his fingers lightly on the table, making a crisp sound. "These subjects are almost exclusively in the hands of aristocratic magicians. Ordinary magicians, especially those without family backgrounds, simply cannot enter this closed circle. Resources, technology, and even their teachings are firmly controlled by the aristocracy."

"They won't easily change their magical foundation. Most of them won't choose your class next semester," Kenneth paused before continuing. "And ultimately, the ones who choose to take your class seriously are those ordinary magicians who don't have much of a future."

"In other words, those magicians without family backgrounds might actually be the ones I can rely on the most," Xing Qingfeng said after a moment's thought. "After all, only they have enough motivation to seek different paths."

"Those who have received traditional magician training since childhood naturally don't have much mathematical literacy," Xing Qingfeng continued, his tone slightly teasing. "On the contrary, civilian magicians who study modern magic often receive secular education and possess the most basic literacy."

"It'll also slow down the Clock Tower's reaction." Kayneth leaned back in his chair, his arms folded across his chest, his demeanor relaxed. "The pressure we're currently experiencing is just the discontent of some third-rate nobles. There's no need to even bother with them. Even the nobles themselves look down on them. We still have plenty of time, so there's no need to rush."

Xing Qingqiu sighed softly, a trace of fatigue flashing in his eyes. He ran his finger over the writing on the test paper and whispered, "There's no point in being impatient. If the average math literacy is too low, I won't be able to continue teaching." He continued grading the papers, saying, "I can only gradually change their perceptions of magic while providing basic math literacy training."

The atmosphere in the office was a bit dull. Kenneth suddenly broke the silence, his voice ringing out again: "By the way, I have another suggestion. If you want to establish your own faction, you can't just focus on people who understand your base."

"I understand that," Xing Qingfu said without looking up. "Those who share my ideals are ultimately a minority. I don't believe that just two simple sentences can make people follow my ideals—"

"——I believe that they will stand with me for the common interests."

"Any ideas?" Kenneth asked again.

Xing Qingqiu continued to flip through the papers, his fingers lightly sweeping across them, seemingly in no rush to respond. The office was so quiet that one could almost hear the ticking of a clock. The air was filled with the scent of ink and books. The cityscape outside the window was tranquil, interrupted only by the occasional car horn, but this didn't affect the atmosphere.

"Yes, but not right now." Xing Qingyu finally raised his head and looked at Kenneth, who sat across from him. "I need to maintain this kind of teaching for about two to three years. Ultimately, there will only be two types of people who stay." He paused, as if pondering the most concise way to express his thoughts. "One type is those who have absolutely no way of their own, and who have no other choice but to resort to this seemingly foolish method—"

"——锍&捌诌武玐O⑷凌儛磷梦. The other type is something that even traditional magic cannot tolerate, an outlier among outliers."

Kenneth didn't rush to respond. He leaned back in his chair, folded his hands on his chest, and listened quietly.

"Traditional magic itself is derived from the extraordinary." Xing Qingqi continued, "And the more unusual the existence, the easier it is to achieve higher attainments in traditional magic—"

"—The more people change, the higher the probability of a genius appearing."

Xing Qingqiu gently placed the test paper in his hand, stroking his fingers lightly on the table as he continued, "Because the course I teach is not something that can be mastered quickly, any magician with a better path would not choose this classroom." He said softly, "Then it will eventually develop into the so-called last glimmer of hope that only those with no other options will choose."

"So you plan to start with the technical aspects?" Kenneth asked with interest. "If you start with the technical aspects, you should see results quickly, and more people will come, right?"

Xing Qingwu shook his head and looked out the window, watching the cars passing by.

"What's the rush?" He responded calmly, his tone somewhat relaxed. "I spent so much time screening and slowing down the results just to ensure that the first batch of students can maintain a high degree of interest bond with me—"

"—Students who cannot truly understand my foundation must follow me and firmly support me. Only then can they learn its practical application later. Otherwise, all the years of learning will be wasted, and they will also be suspected by other factions for studying with me."

"Students who understand my foundation will be rejected because this method itself is a violation of the Clock Tower's existing patent system and its obsession with mystery."

"It won't be too late to consider breaking up with the Clock Tower until we have enough people on our side." Xing Qingqiu's tone became even calmer. "Besides, the official cooperation with the Spiral Pavilion will have to wait for two years. If we're in such a hurry to clean up the Clock Tower, where will I find so many magicians?"

"Since you have your own plans, I won't say much." Kenneth chuckled, his tone calm and unhurried. "I have some other things to do for now, so I can't stay in the Clock Tower. If you have any questions about the distribution of factions and other matters related to the Clock Tower, just contact him directly."

"Isn't Weber still on vacation? Why is he back to work so soon?" Xing Qingyu asked with a hint of curiosity in his tone.

"He volunteered to work overtime," Kenneth said, stretching. "I had no choice but to let him continue working."

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

In the days that followed, Xing Qingfu methodically progressed through the remaining open classes. Starting with basic magic, séance magic, and mineral magic, he explained each subject in a concise and structured manner. Throughout the class, the blackboard continuously filled with symbols, formulas, and images, and Xing Qingfu paused periodically to meticulously explain every detail.

One day, Xing Qingqiu stood at the podium, waving his fingers with white chalk as he wrote down the key points on the blackboard. The scraping sound of the chalk tip echoed in the quiet classroom, occasionally interweaving with the students' murmurs.

"Is there any classmate who can tell me why we can't just use untreated mercury to make elixirs?" Xing Qingyu raised his head and looked at the students in the classroom.

A student sitting in the front row quickly raised his hand, his eyes flashing with confidence.

"Mercury is spiritual in nature. When magical power is used to force it to react with organic salts or sulfur, the resulting product, if ingested, will favor the place where your spirit resides," the student replied quickly. "However, mercury is also toxic. If left untreated, it will harm the user's spirit."

"Yeah, that's a very traditional explanation." Xing Qingyu nodded slightly, a satisfied look on his face. "But next time, remember to answer after I call on you."

Xing Qingyu smiled faintly, then changed the subject, his gaze growing penetrating. "But have you ever observed how mercury arrived at your spiritual abode?" He paused, glancing around, awaiting the students' response. The classroom was silent, all eyes fixed on Xing Qingyu, as if waiting for him to reveal the answer.

Xing Qingfeng looked at the students' bewildered expressions, gently stroked his chin, and then walked to the podium. A small, cloth-wrapped cube sat on the platform. As he approached, he said in a brisk voice, "Next, I'll show you how mercury arrived at the abode of the spirit of life."

He lifted the cloth to reveal the contents underneath: several little white mice were quietly squatting in the cage. Xing Qingqi lifted the cage and showed the mice inside to the students.

"I've prepared these mice for today's experiment," he said, gently shaking the cage. "Next, I'm going to inject mercury into them and use magic to map the movement of mercury through the mice's bodies."

Xing Qingfeng held the syringe steady in his hand. His gaze focused as his fingertips gently twisted the syringe, the metallic sheen reflecting off his palm as a thin ray of light. With a slight hiss, a small amount of diluted liquid mercury slowly flowed into the mouse's body. Instantly, the skin around the injection point bulged slightly, and traces of the liquid rapidly spread throughout the mouse's body.

At the same time, magic flowed through his fingertips, lightly and precisely guiding the mercury's trajectory through the mouse's body. The light in the air was slightly distorted and gradually began to flow across the mouse's body.

"Initially, the mercury was injected into the mouse's vascular system. As the blood flowed, it was quickly carried to the heart," Xing Qingqi explained while holding the mouse. "Then it quickly spread throughout the blood system, from the arteries to the veins, and then through the tiny capillaries."

In the mouse's lungs, mercury exchanges with oxygen. Through the expansion and contraction of the alveoli, tiny liquid particles are carried further into the bloodstream along with the air. However, the mercury doesn't remain there for long. It continues to flow through the blood, passing through the arteries and entering the mouse's various organs. As it gradually spreads, Xing Qingjiu's magic slowly weaves its path like fine threads, creating spiderweb-like trails in the air.

"You can see that the spread of mercury isn't just a physical flow; it's beginning to affect the mouse's nervous system," Xing Qingqi said softly. The mercury's flow didn't stop; it eventually entered the mouse's brain through the bloodstream. The blood-brain barrier doesn't easily admit anything, but mercury, thanks to its tiny molecular structure and magical guidance, seems to have successfully breached it. As the mercury gradually diffused within the mouse's brain, it began to flow along the nervous system's pathways, silently traversing the connections between neurons.

"The mice's minds began to be affected." Xing Qingqi's voice deepened. "Mercury gradually accumulated in the brain and began to intertwine with nerve conduction."

Over time, the mercury began to interfere with the mice's normal physiological functions. The mice became increasingly sluggish, their reactions became less sharp, their limbs weakened, their movements became uncoordinated, and they lost their sense of balance.

"Eventually, the mercury almost completely accumulated in the mouse's brain, particularly at the junction of the cerebral cortex and the hippocampus," Xing Qingfeng slowly withdrew his fingers, ceasing the guidance of the magic. The glow in the air gradually dissipated, and the mercury's flow path disappeared. The mouse had collapsed in the cage, its limbs twitching slightly, its eyes dull, clearly in a coma-like state.

"This is how mercury spreads in the body through the blood and nervous system, and eventually accumulates in the core areas of mental activity." Xing Qingqi put down the mouse in his hand and said lightly.

He suddenly turned, picked up a new syringe from the desk, and gently raised it to his eyes, as if examining its contents. His fingers were steady as a rock, his movements smooth and natural. Then he unbuttoned his shirt, revealing a hint of his upper body. The delicate lines of his muscles were accentuated by the dim light, and the contours beneath his vest revealed a sturdy, well-trained physique.

Without hesitation, Xing Qingfeng gently lifted the hem of his vest, exposing the skin on his shoulder. Then, he aimed the needle at his muscle and calmly inserted it into his skin.

"In daily alchemical activities, mercury, as a commonly used reagent, often leads to many accidental poisonings." Xing Qingfeng said quietly, "Mercury poisoning occurs very frequently, especially among those engaged in alchemy and magic research. Frequent exposure makes poisoning almost a normal occurrence—"

"—Next, I will show you how mercury flows through the human body and teach you how to treat mercury poisoning using the simplest magic."

————————————————————

It's exam week, so I'll just write this much for now, I really don't have the energy (

Although it is a complete challenge and destruction to the patent system of the Clock Tower, everything has a gradual process. At the beginning, the protagonist is only considered to be similar to the image of the second generation in the original work, that is, the so-called "plundering prince".

Only after the protagonist has gathered all the talents that can be used in the Clock Tower over and over again, and gradually mastered the modern magic department and completed the cooperation with the Spiral Pavilion, will he consider turning the table over. After all, he is not just here to kill people like the Bull Lord back then (

Volume 3: Xing Qingfeng's Perfect Arithmetic Classroom: . Are you from Atlas Academy? I think I am!

The needle pierced the muscle with pinpoint precision, almost without hesitation. The mercury flowed through the needle and rapidly entered his bloodstream. At that moment, Xing Qing's fingers twitched slightly, and the magical power at his fingertips began to flow quietly, like weaving an invisible web.

As the magic was constructed, a transparent light emanated from Xing Qingjiu's fingers, gradually covering his entire body. The light wasn't blinding, but rather like the gentle morning light, gently illuminating every inch of his flesh. His fingers gently wavered in the air, and magic rapidly flowed through his bloodstream, beginning to chart the path of the mercury.

"First, the mercury entered my bloodstream through my veins, flowing to the muscles of my right upper arm and elbow." Xing Qingqi's gaze followed the guidance of his fingers, quietly observing the changes in his blood vessels. At this moment, the magical light in the air gradually gathered in his upper arm, flowing along the veins. The light extended along the blood vessels, indicating the path of the mercury.

"These pathways, like blood vessels, carry mercury to various locations through blood flow."

As time passed, the mercury liquid continued to flow in the blood and began to flow downstream into the chest cavity. Xing Qingqi gently turned his fingers, and the magic light began to become more condensed, with a faint purple halo on the surface, like a warning to the flow of mercury in the blood vessels.

"At this point, the mercury has already begun flowing through my liver. The liver is an important filtering organ. While its primary function is to remove harmful substances from the blood, it lacks sufficient detoxification capacity for metallic toxins like mercury," Xing Qingqi continued, his voice gentle and calm. "As mercury flows through the liver, since it's carried in the blood, it will remain there for a period of time. Some of the mercury will be absorbed by the liver's cells, but it won't be completely detoxified."

"The flow of mercury won't stop. It will eventually continue to flow to the next important node, my nervous system," Xing Qingqi continued to explain. "But at this stage, if we can temporarily block the blood flow to the liver through magic, the mercury will not continue to flow to other parts. Especially in emergency situations, blocking the blood vessels near the liver can effectively slow the spread of mercury."

Xing Qingjiu gently wavered his fingers once more, and the light in the air grew even more concentrated and dazzling, accompanied by a faint purple mist, marking the trajectory of the mercury even more clearly. At this point, a faint glow appeared at the location of his liver, indicating that the mercury had passed this stop and continued its flow upstream.

"Next, the mercury flowed into my lungs," Xing Qingqi explained. "Although the lungs aren't a major blood-filtering organ, they have a vast network of blood vessels. After gas exchange, the blood is sent back to the heart and then re-enters the general circulation. At this point, the mercury diffuses through the blood vessels in the lungs throughout the body, beginning to flow to other vital organs, particularly the brain and nervous system."

"If we can block the blood flow to the lungs at this point, the spread of mercury can be effectively prevented," Xing Qingqi continued, his tone remaining steady. "If the blood vessels in the lungs are blocked, the mercury won't be able to enter the general circulation, which at least buys time for subsequent treatment."

He paused for a moment, then waved his fingers again, and the trail of magic extended to his head.

"You can see that this magic power is beginning to approach my brain. If the lungs and liver aren't sealed in time, the mercury will continue to flow through the general circulation and eventually reach the head." Xing Qingyu's gaze gradually shifted upward, pointing to his own brain. "At this point, the mercury will cross the blood-brain barrier and enter the brain. If mercury accumulates in the cerebral cortex and hippocampus, it will directly affect memory, cognitive function, and mental state, causing fatal damage."

With a slight movement of his fingers, a glow slowly gathered around his head, like a thin film of light, revealing the path of the mercury. The light grew fainter in the air, as if symbolizing the increasing speed at which the mercury was entering his brain. Xing Qingqi's expression remained unchanged as he continued, "This area is the most critical node. If we can promptly seal off the blood flow and prevent the mercury from entering the brain, we might be able to avert serious consequences."

"At this stage," Xing Qingqiu's voice, deep and clear, echoed throughout the classroom, "mercury begins to cross the blood-brain barrier and accumulate at the junction of the cerebral cortex and hippocampus." The magic trail above the podium continued to shimmer like a stream of light, converging on Xing Qingqiu's head. "This is the core area of memory and mental activity. Once mercury accumulates here, it directly affects brain function, leading to cognitive impairment, mental confusion, and even hallucinations."

"This is one of the most typical pathways for mercury to move through the body. If we don't intervene promptly, the consequences could be very serious." Xing Qingqiu's gaze swept across the students. "First and foremost, I want to emphasize one thing for you all—"

"—What I'm currently teaching is emergency self-rescue methods, ways to buy yourself more time," Xing Qingqu emphasized. "I hope everyone remembers one thing: if you can handle mercury poisoning on your own, then you won't make such a simple mistake during the alchemy process. So if you encounter a problem, remember to seek help from others immediately."

"Of course, if your level can reach my level..." He paused slightly, stretched out his fingers, and instantly gathered a small amount of compressed magic power at his fingertips. "Then there is actually no need for any first aid measures-"

Before he finished speaking, Xing Qingqiu flicked his finger, and magical power gushed out. In that instant, the air seemed to be suddenly ripped apart, and then several screams and shocked whispers rang out from the classroom. Xing Qingqiu's head was instantly torn apart, and hairline cracks quickly spread throughout his head, almost without any warning.

But the expected scene of blood, flesh, and brains flying everywhere did not occur before the students' eyes. Xing Qingqi's head instantly shattered like glass, cracks spreading along his skull. His entire face instantly vanished, replaced by an emerald green crystal. The crystal shimmered faintly, its crystalline clarity like a gem fallen from another world. The fragments scattered in the wind, like drifting dust, gradually vanishing into the air.

The screams and chaotic commotion in the classroom suddenly stopped, as if an invisible hand had tightly gripped their necks, and all sounds suddenly stopped. The initial screams and the subsequent whispers were instantly cut off, as if the current had been cut off, and there was silence.

Emerald green crystals began to grow from Xing Qingfu's neck. They rapidly spread upward from the base of his shattered neck, like some strange life form, and then seeped into his body. As these crystals grew, his head slowly returned to its original shape, his flesh and blood recondensed, and his face gradually became clearer, eventually returning to its original appearance.

Most of the students were silent because most of them were still studying basic subjects, so they were naturally amazed when they suddenly saw this scene.

But there were also some students, and even some lecturers, who were there simply to show their support or join in the fun. Some had heard about what Xing Qingjiu had taught in the previous two classes and came to see the joke.

In the previous few open classes, Xing Qingjiu's teaching had already been categorized as modern magic. The classroom of Kenneth, a prominent representative of the aristocracy, was now being used to teach modern magic, which the aristocracy considered the most vulgar. Many magicians who already disliked Kenneth came specifically to attend Xing Qingjiu's classes, hoping to see him make a fool of himself if his teaching went awry.

The reason these people remained silent was because they knew very well that the person in front of them was not a magic puppet, or they simply could not see anything strange about Xing Qingjiu in front of them.

At least until Xing Qingqiu voluntarily blew his own head off, none of them noticed anything unusual about him. This meant that his attainments in the magic arts were likely far superior to their own.

The other party was not a fledgling gilded household at all, but a magician who was on the same level as himself or even superior to him in the way of magic.

"Humans are rare computing devices with motor functions. We are intelligent life forms that have evolved to collect and analyze intelligence, and to directly address the many inherent problems through labor," Xing Qingqi emphasized. "And if you can't treat your brain as freely as I do, you must pay attention. It's not just mercury. After ingesting any toxic substance, what you need to do is to set up restrictions and filters before the blood-brain barrier—"

"—Other organs are easy to deal with, but your brain is seriously damaged and there's no way to recover."

"Let me summarize," Xing Qingqi spread his hands and looked at the silent students. "The first step is to quickly identify the key points of mercury flow and temporarily block the blood flow to these areas through magic. The liver, lungs, and brain are the three key points of mercury flow in the body. If we can effectively block these areas, we can effectively slow the spread of mercury and maximize the effectiveness of first aid."

"But this only happens when injected," Xing Qingqi turned and picked up two small bottles from the desk. One bottle contained liquid mercury, and the other contained mercury vapor that had turned into gas. "The two most common ways of poisoning are taking unprocessed mercury and accidentally inhaling mercury vapor during alchemy—"

"—Next, I will show you the emergency self-rescue methods for these two situations one by one."
