"Briefly introduce yourself...... Yudula, a four-star elemental wizard, fire is one of the elements I major in. In the stereoscopic projection scene, the red-haired wizard habitually brushes the ends of her hair, which is quite sultry, but her voice sounds a little hoarse, which does not match her appearance.

Roger's attention wasn't focused on her appearance at all.

"A four-star wizard, is he actually a mid-level wizard....... ”

Looking at the red-haired woman in the projection, Roger listened carefully to every word she said, and did not dare to underestimate it at all, although the red-haired wizard was slightly weaker than his notorious mentor in the projection, but who knows when this photo was recorded.

If it was taken a long time ago, who would dare to assert that this witch named Eudullah has not reached a higher level now? For a median wizard, even if he is only the weakest four-star wizard among the median wizards, the lifespan has already exceeded a thousand years, and for some median wizards with special paths, it is not uncommon to live for thousands of years, everything is possible!

These distractions only flashed for a moment, and Roger's attention was once again on the photo.

"Considering that the Little Fireball Technique is one of the basic spells of fire-based spells, the person who can see this photo, even if it is not the first time to contact spells, should be in the beginner wizard apprentice stage...... So, here I'm going to start by explaining what exactly a spell is......"

With that, the red-haired wizard stretched out her right hand, and a ball-sized fireball suddenly appeared above her palm, hovering there, motionless.

"This is what the Little Fireball Spell looks like, for me now, there is no need to chant or prepare to release this level 1 spell, in common terms, this is called silent spell, and it is usually something that a wizard can only do when he releases a spell that is far below his own level. The red-haired wizard swung her right hand slightly, and the small fireball circled around her hand.

When the small fireball circled back above her palm again, she suddenly raised her hand and pinched it towards the small fireball, and in an instant the fireball disappeared in her palm, and her voice resumed: "But why do wizards need to prepare or chant when casting spells that are not lower than their own level? and why can they be silent when they release low-level spells? If you don't know why, it means that you don't know what a spell is." ”

The red-haired wizard paused for a moment when she said this, probably to give the viewer some time to think.

And Roger was indeed stunned for a moment, and his mind began to think quickly.

"yes, why is that?" Roger frowned.

Before that, he felt that he already knew a lot about wizards, and even before joining the Academy, he had been in contact with more than one official wizard as a Grand Knight.

In the case of Oliver's two-star wizard's mentor, Roger had met him several times, not to mention that he had made up a lot of common sense about wizards in the nearly year since he joined the Academy.

However, even in this case, when the red-haired wizard said the seemingly simple question of 'what is a spell', Roger suddenly realized that he really didn't know!

All along, he habitually ignored this problem, just like breathing, who would have nothing to pay attention to how others breathed, why did they need to breathe? The spells he saw were chanting and casting, it was like a fixed process, and it should be normal like this.

"But why don't high-level wizards need to chant when they cast low-level spells?" Rubbing his forehead, Roger only felt that his train of thought had reached a dead end.

At this moment, the red-haired witch's hoarse voice sounded again, "...... As I said before, to understand this, you first need to know what a spell is. ”

"I'm an elemental wizard, so I'll use elemental spells as an example...... When you start learning elemental spells, you will find that a spell, whether it is a low-level spell or a high-level spell, has one thing in common - it has a unique 'rune array'!"

"Spellcasting, from the root point, is actually just using your own spiritual power to outline each important node of different 'rune arrays' in the spiritual sea, and your sensitivity to the elements is the basic condition that you can gather a certain element and use that element to connect the nodes that have been outlined with spiritual power...... In other words, if you want to practice a certain spell, you must meet three conditions at the same time - rune formation, spiritual power, and elemental induction, all three of which are indispensable!"

"Generally speaking, the more high-level spells, the more complex the rune array, and for low-level wizards, it is impossible to even remember some high-level spells with complex rune arrays. ”

The red-haired wizard said lightly.

"I see!"

Hearing the red-haired wizard's explanation undoubtedly opened the door to a new world for Roger, and the original confusion was instantly solved and became enlightened.

"The several level 0 spells I have originally practiced basically only have two or three spiritual power nodes, so I don't need to bother to sketch any rune formations, plus I have never learned the casting method of spells above level 0, so naturally there is no way to compare. ”

"But hearing her say this, everything does seem much more reasonable, no wonder low-level wizards can't learn high-level spells...... Take myself as an example, as far as my current spiritual power is concerned, at most, I am afraid that I can only create less than ten spiritual nodes in the spiritual sea, and if I have more, I will be powerless, in this case, of course, it is impossible to outline a very complex rune array. ”

"However, since the casting of spells only needs to be done in the spiritual sea, why chant?" Roger was a little confused when he thought of this.

As if hearing Roger's question, the red-haired wizard continued, "Hearing this, you may have a question, since spell casting can be done in the spirit sea in principle, why do many wizards, especially those low-level wizards, chant before casting spells?"

"It's just as simple...... Chanting has never been a requirement for casting spells! The reason why many wizards chant before casting spells is simply to concentrate!"

"For any wizard, for whatever reason, he will face countless battles in his life. The red-haired wizard's tone was calm, but Roger noticed that her gaze looked full of vicissitudes, "It's very difficult for a low-level wizard to calm down during battle, and it happens that all that is needed to cast a spell is to be preoccupied......

In other words, even if you are proficient in the entire process of casting a spell, you will not be able to release that spell if you can't calm down...... Chanting is just a means created by our predecessors to help you concentrate, and when you chant, your mind will naturally focus on casting spells, which seems to be a kind of conditioned reflex. ”

"And the reason why high-level wizards don't need to chant at all when they release low-level spells is also very simple, because with their huge spiritual power, if they want to outline the rune array of low-level spells, they don't need to concentrate at all, they just need to pay a little attention. ”

The red-haired wizard paused when she said this, "Okay, I've basically explained all the questions that need to be explained, and when you hear this, you must have understood what a spell is fundamentally." ”

"Without further ado, next, I'm going to show you what the rune formation of the Little Fireball Technique looks like, and teach you how to practice it. ”

Roger was still immersed in the red-haired wizard's explanation, and when he heard this, he had to stop thinking and concentrate on starting to learn.

After all, that's why he paid for his contributions.
