"He's been nowhere to be seen all day, but he seems to be quite prepared, huh?" Riel muttered quietly. He also felt that Ivan's answer was indeed very standard, almost exactly the same as the answer he had organized.

"Well, it seems that he has put a lot of effort into it. Alan nodded.

Ian, on the other hand, looked grim-faced, seemingly unconcerned about Professor Rochel's question, and didn't even raise his hand.

However, Ravan still missed a common feature, that is, the difficulty of space-time magic is generally very high. Professor Rochelle added, "There are clear levels of difficulty in general, elemental, and medical magic, and almost all of them are distributed from B to ED levels, but space-time magic is different, and the simplest space-time magic level is also D, and there are some levels that have reached ED that is difficult for ordinary people to master." As a result, another distinguishing feature of space-time magic is that it is extremely difficult - the most difficult of all magic classes overall. ”

Riel was a little unsettled at this moment, and hearing Professor Rochelle tell him this so seriously made him feel less confident for a moment.

"Can anyone explain to me why space-time magic is so difficult?" Professor Rochelle asked, looking around the classroom.

Now no one is vying to raise their hands, because the first two questions are clearly written in the textbook, but this question is not explicitly stated in the textbook, and you need to really remember and understand the content of the textbook before you can come up with an answer.

Due to the similarities to what Alan had explained to Rare earlier, he prepared a little faster than the others. However, in order to answer as perfectly as possible, Alan still mentally examined the answer a little more before raising his hand.

But to his surprise, just as he raised his hand in mid-air, Professor Rochel's voice rang out: "Good boy, Ivan Lavin!"

Alan was stunned for a moment, only to realize that in the tens of seconds he had just organized the answer, Ivan had already raised his hand.

Almost everyone's eyes converged on Ivan's side.

"There are three difficulties in space-time magic. Ivan looked confident: "First, compared to other types of magic, space-time magic requires the caster to have a fairly good memory and imagination. This is because other spells only need to make the correct gestures during the chanting of the spell to achieve their effects, but the use of space-time magic requires the caster to imagine in as much detail as possible at the same time, and construct a specific picture of the destination to be reached in the mind. ”

Professor Rochelle nodded with satisfaction, "Please continue." ”

"Second, although all magic requires a high level of mental concentration during the casting process, it is even more difficult for space-time magic. This is because the preparation and casting process of most magic spells is very short, while space-time magic is more special. In the case of space magic, the preparation time and the time it takes to cast a spell will increase depending on the distance to the destination. In this way, what would have been a short concentration has become a long period of high concentration, and the difficulty has been directly increased by several notches. ”

"Not bad. ”

"3. The most difficult part of space-time magic is the chanting of incantations. As we all know, the length of spells in magic generally increases with increasing difficulty, and the general difficulty level of space-time magic is high, which means that there are a large number of complex spells that need to be memorized, but this is not the most difficult part, the most difficult part is that the appropriate action instructions need to be performed during the chanting of the spell...... Magic is generally easier to learn because of the short spells and simple action commands, and it doesn't take a long time to practice repeatedly to become proficient in combining the speed of speech with the appropriate rate of movement. Not only does the length of the spell mean more action commands required, but the right fit between the two becomes a challenge. What's even more difficult is that you need to be proficient in both while maintaining a high level of mental concentration, and not disrupting the image you have built in your mind by thinking about the mantra you are about to chant and the movements that need to be executed. ”

"Very good! very detailed!" Professor Rochelle was also a little excited, and did not hesitate to praise himself, "I can see that you have prepared quite well before class, and this answer is worthy of my ten points!"

There was also a round of applause in the classroom.

"You may be seated. Professor Rochelle waved his hand to signal Ivan to sit down, and then continued with the question: "As Raven just said, the difficulty of space-time magic lies in these three points: whether there is enough talent, that is, imagination, whether the spirit can ensure a high level of concentration throughout the whole process, and the memory and chanting of the incantation. ”

Professor Rochelle wrote these three points on the blackboard, and everyone began to write them down.

"Imagination is something you are born with, and you can think of it as you grow up. But no matter how you get it, the lack of imagination can be compensated for by some special training later. The real difficulty lies in the latter two. Professor Rochelle said, gesturing, "Unlike other types of magic, which fail to cast due to distraction, the consequences of failed spells in space-time magic are much more severe. For example, if the casting of elemental magic fails, at most, it will not be able to generate or channel a certain element smoothly, and it will not be able to obtain any effect, but once the temporal magic fails, it may bring about the caster's mysterious disappearance, injury, or even death...... In order to solve this problem, Krivari's security department also specially created special signs for memory and imagination, and marked the distance between each other clearly on them, so that the caster could estimate the amount of magic power that would need to be consumed. But despite this, dozens of similar disappearances are received every year, and the missing people are basically due to a lack of concentration during the spell casting process, so the images imagined at the moment when the incantation is chanted are different from the real destination, so they are sent to other inexplicable places. ”

There was silence in the classroom, after all, this was a matter of his own life in the future, and no one dared to be distracted.

"Imagine that after you have cast a lot of magic and chanted a spell, what will happen to your mind is not the destination you want to reach, but an ordinary grassland, or a tree?" Professor Rochelle said word for word, "You know, the meadows and woods that are suitable for your reach, and that match the magic you cast, can be found everywhere. If you're going to a place that's closer, you won't get lost, but if you're going to a remote place, for example, from here to Krivari City, where grasslands and woods abound, can you still guarantee that you'll be found alive?"

Everyone began to panic and exchanged heads, and some people even began to retreat in their hearts.

However, Professor Rochel suddenly smiled, and the tone of his words changed: "But don't worry, except for those who take this course, you can't use it, you only need to understand a few relevant theories, and all the students who major in this course, I will accompany you to practice alone one by one, until you develop the correct habit of casting spells, and it is difficult to make mistakes." ”

Professor Rochelle's words sounded quite reassuring, at least for a moment, and Riel felt less resistant to studying the subject.

"But only if you have to overcome one difficulty, which is the coordination between chanting, action commands, and picture construction. "Every year, there is no shortage of extremely talented people who can easily do it without practice. But don't be too frustrated even if you can't do it right away, I can tell you a little trick, and that's to practice, practice and practice like crazy, until the chanting of mantras and the execution of action commands become something that is done subconsciously...... In other words, the chanting of the incantation and the execution of the action instructions are done unconsciously, so that all the energy can be focused on the construction of the picture in the mind, so as to ensure that the casting process is foolproof. ”

"When practicing, you only need to choose two different locations, one far and one near, and then memorize the approximate magic power required to go to these two places, and through repeated practice between these three places, you can coordinate the chanting speed of the spell and the casting rate of the action command to the best state, and then when you want to go to other places, you only need to refer to the magic power required when you go to these two places. ”

As soon as I heard that there was a trick, the atmosphere in the class was relaxed again.

"However, compared to the riskier space magic, I think that some time magic is more useful to you at this stage, and it is easier for you to accept. Professor Rochelle turned around and wrote on the blackboard as he spoke, "I'm going to start by exposing you to one of the most useful time spells, the 'Tempting Spell'. ”

Riel was excited, sat upright, and finally talked about what interested him.

"So before I get started, I want to ask, how much do you know about the 'time' thing?" Professor Rochelle began with a small question.

Unsurprisingly, it was Ivan who raised his hand first.

"Time is a rather abstract concept that cannot be touched and controlled, yet it surrounds us all the time. Ivan said, "Human strength and energy are limited in the day, and by clarifying the concept of time, human beings divide the day into different periods, so as to develop different habits, do different things, and spend the day more efficiently." ”

"That's a good point, so here's the problem......" Professor Rochelle asked, pacing a few steps, "is it true that everyone experiences the same amount of time?"

"Yes, time is fair, and everyone is under the same 'big time' management. ”

Professor Rochelle smiled lightly when he heard this: "Then today, this 'Slow Time Charm' that I want to teach you is a magical magic that allows us to be in the same room, but we can experience different lengths of time!"
