Green didn't know the pace of teaching in Yode Village, but the entry requirement for the Lisbon Junior School of Magic was to master any of the spells before the age of thirteen. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

According to Green's idea, no matter how "salted" the children of Yode Village are, the gap should not be too big. However, the results were very bad.

Not to mention solid geometry, not even plane geometry and algebra!

The best grades are only able to add, subtract, multiply and divide in two digits, which is unexpected, but it makes sense - after all, it is only a group of elementary school students in their early teens, and even the oldest of them is the equivalent of a junior high school student on the planet.

But in this way, Green was a little blind: "If you don't know spatial geometry, how do you draw a spell model?" Green couldn't help but look at the old mage at the end, "Old Tom, don't you need to draw a magic model in your head when you cast a spell?" ”

Old Tom came back to his senses from his contemplation: "Of course you need to, if you don't even have a model, you won't be able to gather magic at all." ”

Greene: "But these kids have never learned spatial geometry, so how do they build models in their minds?" ”

Old Tom said with an embarrassed expression, "Spell model...... As long as the shape is about the same, as long as the casting gestures and spells are correct, the model just needs to look about the same. ”

Hearing Old Tom's words, Green raised his eyebrows: "Almost?" ”

"Hmm." Old Tom nodded, "That's pretty much it." ”

Green looked back at the model on the blackboard, looked down and thought about it, then took the phosphomoss out of his pocket and began to cast the spell.

Gesture...... Perfect.

Model...... Sketch. Just have a rough shape.

Incantations...... Perfect.

"Illumination!"

The mana was consumed, but there was no reaction at all.

"Sure enough, is the error of the spell model too big?"

Green looked down and thought about it, and began to recast the spell again.

This time, Green slightly improved the accuracy of some of the models.

"Illumination!"

A small ball of light appeared in Grimm's hand.

"Is it really almost enough?" Grimm's previous model sketches were all sketched with a ruler and a pen, with extremely high accuracy, but now he uses a pen to draw quickly, and the accuracy error is much higher, and it is possible that the spell casting fails, but the casting speed has also increased.

Obviously, a ruler would take much more time to sketch than this kind of sketching, and it would save Green a lot of time.

Suddenly, a flash of inspiration flashed in Green's mind!

Wait a minute! Could it be that [Spell Instant] is also like this?

Green pulled a piece of cooked skin out of his pocket and prepared to cast his best spell, Mage Armor.

Gesture...... Perfect!

Model...... Sketch...... I rub!? I haven't painted it yet, so why is the model built!?

Green's mind was in turmoil, and the spell failed instantly.

Calm, calm down.

Green began casting spells again.

Gesture...... Perfect!

Model...... Replication is done in an instant.

Incantations...... Streamline.

"Mage Armor!"

As soon as Green's voice fell, a transparent armor appeared on Green's body.

Green carefully reflected on the previous spell casting process: "I see. Spell Burst is a 'copy and paste' style of quick modeling, rather than a slow manual drawing. I just started and the model was pasted. I hadn't even noticed that before. ”

"The principle of the instantaneous spell is clear. Let's try spell fixing. ”

Removing the mage armor from his body, Green began to cast spells again.

Gesture...... Omit.

Model...... Perfect.

Incantations...... Perfect.

"Mage Armor!"

Nothing happened......

"Strange, can't gestures be omitted? What's the problem? ”

Just when Green wanted to continue experimenting, Old Tom finally couldn't help but open his mouth to wake up Green.

Old Tom: "That...... Mr. Green. ”

"Huh?" Green looked up.

"I'm still in class......

Green rubbed his head, "Ah, I'm sorry. Because I thought of something, I forgot about it for a while. ”

"It's fine. Mr. Green, could you please explain to us the ...... you just said," the old mage looked at the blackboard, "the three-dimensional coordinate system?" ”

"Well......" Green glanced back at the blackboard, "this is over-the-top." These kids are supposed to be learning algebra and plane geometry now, right? ”

"No, the ......," the old mage squirmed, "I would like you to explain a little bit so that I can learn a little bit as well." ”

Green was shocked: "You can't and won't have three-dimensional geometry, right?" ”

"Haha." The old mage smiled awkwardly, "My spells are wild paths, and I learned them all by myself, so ...... That, I don't really understand some of the high-end theories of your academic school. ”

Green looked at the old mage with a subtle expression: "I see. ”

The average architect first learns to draw and then begins to build a house. And the old mage in front of him is the kind of "old craftsman" who can't read architectural drawings at all, but can still build a house with experience.

When it comes to building some simple houses, the "old craftsman" can make do with it, but once the house structure is too complicated, the "old craftsman" is a bit blind.

The same applies to the mage. Due to the lack of sufficient theoretical support, the early stage is fine, and it can be dealt with by experience, but it is a bit blind in the later stage. And the old mage seemed to be aware of this, so he took the initiative to ask Green for advice.

And Green didn't hide his secrets, and took the initiative to explain the relevant rules.

The children in the classroom were confused, but Old Tom's eyes were getting brighter and brighter!

Tom Sr.: "I see, with this three-dimensional coordinate system, it's much easier to understand the spell model!" However, although this spell model can accurately outline the zero ring and the first ring spell, it ...... What about the two-ring spells? ”

"Just add one more variable to the 3D coordinate system and make it a 4D coordinate system."

"Four-dimensional coordinate system?" Old Tom looked at his fingers and frowned, "Three-dimensional? Variable? Four-dimensional? Is there a fourth dimension to space? ”

"The two-ring spell does involve a four-dimensional space, and if you can't understand it, even if you advance to a transcendent mage, you may not be able to learn the two-ring spell." Green paused, "Come on." ”

"Transcendent mage...... the old mage suddenly shook his head with a wry smile, "I'm afraid I won't have a chance in this life." ”

"Huh? Could it be that you have failed to advance in the past? ”

"Yes." The old mage smiled wryly, "Not only did the advancement fail, but my demon also died. ”

"Condolences." Failure to advance will lose attributes and mana, and if the demon dies, some mana will be lost, and the success rate of the advance will become ugly.

The old mage looked at Mona, who was following Green, "Is your demon a man-made demon?" It looks quite special, not only does it have a certain amount of intelligence, but it also seems to be able to classify and proliferate. ”

The corners of Green's mouth twitched slightly, without explanation.

Demons? Green didn't know where his demon was, the only thing he knew for sure was that it was still alive, and its location was changing every day, and there was no way to locate it.
