Green was not sure about the teaching progress of Yode Village, but the admission requirement for Lisbon Junior Magic Academy is to master any spell before the age of thirteen.

According to Green's idea, no matter how "salted fish" the children in Yoder Village are, the gap should not be too big. However, the result is very bad.

Not to mention three-dimensional geometry, even plane geometry and algebra can’t be!

Children with the best grades can only add, subtract, multiply and divide by double digits. This result is beyond expectations, but it is reasonable - after all, it is just a group of elementary school students in their early teens, and even the oldest ones are equivalent to junior high school students on Earth.

But in this way, Green was a little confused: "If you don't know how to draw a spell model?" Green couldn't help looking at the last old mage, "Old Tom, don't you need to draw a magic model in your head when you cast spells?"

Old Tom came back from his meditation: "Of course, if you don't even have a model, your magic will not be gathered at all."

Green: "But these children have never learned spatial geometry at all. How can they build models in their minds?"

Old Tom said with an awkward look: "For the spell model... it is enough as long as the shape is similar. As long as the casting gestures and spells are correct, the model is enough as long as the model looks similar."

Hearing Old Tom's words, Green raised his eyebrows: "It's almost enough?"

"Yeah." Old Tom nodded, "It's almost done."

Green looked back at the model on the blackboard, lowered his head and thought, took out the phosphorus moss from his pocket and started casting the spell.

Gestures…perfect.

Model...sketch. Just have a rough shape.

The spell…perfect.

"Lighting Technique!"

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

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

Green lowered his head and thought about it, and started casting the spell again.

This time, Green slightly improved the accuracy of the model.

"Lighting Technique!"

A small ball of light appeared in Green's hands.

"It's really almost the same?" Green's model outline was outlined with a ruler and a pen before, with extremely high accuracy. Now he uses a pen to draw quickly, with a much higher accuracy error. It may fail to cast, but the casting speed has also been improved a little.

Obviously, the time spent carefully outlining with a ruler is far more than this sketch drawing, and using this method can save Green a lot of time.

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

Wait! Could it be that [Spell Instant] is the same?

Green took out a piece of cooked skin from his pocket and prepared to cast his spell, the mage armor, which he was best at.

Gestures…perfect!

Model...sketch...I'm sorry!? I haven't drawn it yet, why did the model be built!?

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

Calm, calm.

Green started casting again.

Gestures…perfect!

The model...copy in an instant.

Spell…simplified.

"Master Armor!"

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

Green carefully recalled the previous casting process: "So that's it. The spell instant is a quick modeling of 'copy-paste', rather than a manual drawing. I just started and the model was pasted. I didn't notice this before."

"The principle of spell instant is to figure it out. Next, try the spell fixed-on."

After canceling the mage armor on his body, Green began casting spells again.

Gestures... omitted.

The model...perfect.

The spell…perfect.

"Master Armor!"

No reaction...

"Strange, can't the gesture be omitted? Where exactly is the problem?"

Just when Green wanted to continue the experiment, Old Tom finally couldn't help but wake up Green.

Old Tom: "That...Mr. Green."

"Hmm?" Green looked up.

“It’s still in class…”

Green rubbed his head: "Ah, sorry. I thought of something, so I forgot about it for a moment."

"It's okay. Mr. Green, please explain to us what you just said..." The old mage looked at the blackboard, "Is the three-dimensional coordinate system?"

"This..." Green looked back at the blackboard, "This is beyond the standard. What these children should learn now is algebra and plane geometry, right?"

"No, that..." the old mage was a little embarrassed, "I hope you can explain it a little so that I can learn it as well."

Green was shocked: "You can't and can't do three-dimensional geometry, are you?"

"Haha." The old mage smiled awkwardly, "My spells are wild ways, and I learned them randomly, so... that, I don't quite understand some of the high-end theories of your academy."

Green looked at the old mage with a subtle face: "So that's it."

Ordinary architects first learn to draw, and then start to learn to build houses. The old wizard in front of him is the kind of "old craftsman" who cannot understand architectural drawings at all but can still build houses based on experience.

When building some simple houses, the "old craftsmen" can make do with it, but once the house structure is too complicated, the "old craftsmen" will be a little confused.

This principle applies to the mage. Due to the lack of sufficient theoretical support, it was fine in the early stage and could be dealt with by experience. In the later stage, I was a little confused. The old mage seemed to have noticed this, so he took the initiative to ask Green for advice.

Green did not hide his own personal information and took the initiative to explain the relevant rules.

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

Old Tom: "So that's it. With this three-dimensional coordinate system, it's much easier to understand the spell model! But although this spell model that can accurately outline the zero ring and the first ring spell, what about... the second ring spell?"

"Just add another variable to the three-dimensional coordinate system and make it become a four-dimensional coordinate system."

"Four-dimensional coordinate system?" Old Tom looked at his fingers and frowned, "Is there a fourth dimension in three-dimensional? variable? four-dimensional? space?"

"The second-ring spell does involve four-dimensional space. If you cannot understand it, even if you advance to the extraordinary mage, you may not be able to learn the second-ring spell." Greenton paused, "Come on."

"Extraordinary wizard..." The old wizard suddenly smiled bitterly and shook his head, "I probably won't have a chance in my life."

"Hmm? Could it be that you have failed to advance?"

"Yes." The old mage smiled bitterly, "not only failed to advance, but my devil has also died."

"Jie Ai." Failure to advance will cause attributes and magic power to cause the devil to die, and some magic power to lose. The success rate of advancement will become ugly.

The old mage looked at Mona who was following Green: "Is your demon an artificial demon? It looks very special. Not only does it have a certain wisdom, it also seems to be able to proliferate in a classified manner."

Green's mouth twitched slightly, without explanation.

Demon Green didn't know where his demon is. The only thing he could be sure of is that it is still alive and its location changes every day, and there is no way to position it.
