All-around teacher at the magic academy

"Okay, Harvey, you answer this."

"The fire elemental magic we usually release is not created out of thin air. The reason we can release fire elemental magic is because we construct a magic circle and use the magic circle to operate the magic power we release in a specific way, thereby generating fire element."

"Yes, please have a seat."

Harvey's answer was good; he hadn't followed his own ideas directly when he was teaching him. He initially explained the magical knowledge from the books to him, and only after he became familiar with it did he share some of his own views on magic.

"Harvey's answer isn't entirely correct, but it's not entirely wrong either. If you want to understand how fire elemental magic is released or generated, you need to understand the principles of fire generation."

The reason we can create flames out of thin air is primarily because there is a special gas in our environment that is a necessary condition for the generation of flames.

Consider why it's difficult to unleash fire elemental magic underwater; it's because the amount of this gas is so small that it's insufficient to ignite a flame.

The second point is the magic power we release, which we'll call magical elements for now. These magical elements can be ignited to create flames; they are extremely special. They can take different forms, and each person's magic power, or magical elements, is not exactly the same.

However, according to my research, magical elements can be manipulated at will. This is generally very difficult for most magicians to achieve.

Because few people think about this, most magicians practice directly according to the magic circle. This leads to this crucial factor being easily overlooked.

The third reason is that even with this magical element and the right environment, fire still cannot be generated. We are still missing a very important condition: temperature.

The temperature of a flame is very high. A flame is produced when the temperature reaches a certain level, at which point the magical elements released by ourselves can be ignited and transformed into flame.

So, how exactly can the temperature of magical elements be raised to the point where a flame is ignited? Does anyone know the answer to this?

Leon hoped that a classmate would answer, but unfortunately no one did.

"Alright then, to make the temperature of magical elements reach the limit where they can ignite, the principle is actually not difficult. The reason why everyone can't answer it is simply because they haven't thought about its principle when casting fire elemental magic."

"The general principle of fire magic circles is that we use magical elements to trace the trajectory of the magic circle, thereby making these magical elements active, that is, making them move. These magical elements generate heat through continuous movement, and the faster the movement, the more heat is generated."

As Leon spoke, he lit a flame in his palm. Everyone listened so attentively that they didn't notice that Leon wasn't using a magic circle.

Of course, most magicians are already very skilled at casting such simple spells, and constructing a magic circle is basically a matter of a moment, making it difficult for others to see the changes involved.

"So far, what do you all think is the principle behind the casting of fire elemental magic?"

"Teacher, I think I understand now. To successfully cast fire magic, you need to meet the three conditions you mentioned earlier: environment, magical elements, and temperature, which is the movement of magical elements." A student who was paying close attention quickly summarized the key points.

"Very good, it seems you are thinking about it seriously."

"However, I have a question, teacher. According to what you said, wouldn't it be possible to release fire elemental magic without constructing a magic circle? Then why can magic be released through a magic circle?" Leon thought it was a good question and felt that his classmates were quite knowledgeable.

“Very good, this student seems to have quite a bit of knowledge about magic. What’s your name?” Leon looked at the girl with beautiful blonde hair.

Emma Chloe.

“Very good, please sit down, Emma.”

Leon felt that the name seemed familiar, as if he had seen it somewhere before, but he couldn't remember where.

"To answer your first question, it is true that fire elemental magic can be cast without relying on a magic circle."

Leon's words sparked widespread discussion among the students and even overturned their worldview.

"Furthermore, not only fire elemental magic, but most magic can be cast without relying on a magic circle. In fact, I speculate that all magic can be cast without relying on a magic circle, although there are some that I am not yet aware of. But at least, elemental magic can be cast without relying on a magic circle."

"I know most of you probably won't believe me, so let me show you. It'll be a simple fireball."

As Leon spoke, a reddish-brown fireball appeared in his hand and burned fiercely.

"Teacher, this doesn't mean anything. Perhaps it's just your talent, an isolated case, and it doesn't mean it applies to other magicians," a student retorted.

"No, I've proven that others can do this too, but it does depend on some talent. Because you need to truly understand the so-called magical elements, be able to sense their existence, and be able to change or at least control their form and movement."

"However, I believe this theory applies to most people, after all, some students in this class have mastered it."

Upon hearing Leon's words, everyone looked on incredulously, glancing around as if trying to find this genius.

"Now, let's invite our classmate Harvey to demonstrate for everyone."

Harvey felt embarrassed when Leon called his name and called on him to demonstrate in front of everyone. He wasn't a show-off, but since it was Leon who asked him to do it, he was naturally willing to step forward.

"We cannot let Professor Leon down."

Harvey's magic was taught by Leon, so he naturally knew how to do simple fire elemental magic. Later, when Leon taught Harvey, he rarely showed him how to cast spells using magic circles, believing that constructing magic circles was completely unnecessary for some simple spells.

When Harvey was able to unleash fire magic without using a magic circle, everyone believed him. Seeing the students' shocked expressions, Leon felt he had probably given a pretty good lecture. He glanced at the time; get out of class was almost over. He had to admit, time had flown by.

"We don't have much time left, so I won't let you students demonstrate in class. Those who are interested can practice after class, and I will reward the student who can do it in the next class with a credit. That's all for now, see you next week, everyone."

After giving a brief introduction, Leon left the classroom without waiting for the students' reaction, knowing full well that students hated it when class went on for too long. Leon didn't want to ruin the positive image he had built in their minds.

"Professor Leon, I never expected you to be so amazing. I never even thought of such a thing. It feels incredible."

Teacher Lian caught up with Leon and praised him generously.

"I also conducted in-depth research on this subject out of curiosity, which led me to some conclusions."

"I think this is a groundbreaking advancement for magic. I just don't know if summoning magic can be cast without relying on a magic circle."

"I've thought about this problem and conducted many experiments, but unfortunately, they all failed. I think I must have overlooked some key point, which is why it didn't work. After all, there is a fundamental difference between summoning and elemental magic."

He had this idea before and even read many books on the subject, but unfortunately, he came up with nothing.

"Indeed, but even so it's already amazing. I believe that Teacher Leon will succeed one day."

"Thank you for your blessing. If Professor Lian is interested, we can discuss it together."

"Really? That's wonderful! Please look forward to bothering you again in the future."

"No, it's my honor."

.......

Leon left in a hurry, leaving his classmates with only his back view, which added a layer of mystery to his image in their eyes.

Two of the students who had initially chased after him wanted to ask him more questions, but they stopped when they saw him chatting and laughing with Teacher Lian.

"Why are you able to cast spells without using a magic circle? I think you must be quite familiar with Professor Leon, Harvey."

Emma saw Harvey, who had also come out to chase after her, and asked him seriously.

She absolutely refused to believe that Harvey could master the technique after only hearing it once, and the fact that Professor Leon could call Harvey by his name so familiarly revealed that their relationship was extraordinary.

"Yes, I've known Teacher Leon for a long time, and I learned my magic from him."

My teacher is truly a great person. He not only taught me magic, but also greatly helped me in my life. All the changes in me are due to Teacher Leon's careful guidance..."

Emma's curiosity about Leon deepened as she listened to Harvey's honest confession.

"What kind of person is he, really?"

............

And so, Leon's first lesson came to a successful end, unaware of the changes it would bring to his students.

Of course, all of that is for the future; at least right now, Leon has to think about his night watch.

"Ah, I'm a little tired. I taught a whole class today, so I can't relax at all."

"I'm really afraid the students will say I'm irresponsible. I can't possibly get expelled from the college."

"I hope there will be more students in the next class. If there are still so few, I guess the dean will have a talk with me."

"These days are quite fulfilling, much better than being idle all the time. At least I won't be thinking about unnecessary things lately."

Leon, on his way to the law enforcement division, was deep in thought. He had some expectations for his future, but he didn't know how long this kind of life could last.
