Two hours later, Newmengard Castle.

"I've never seen a stupid guy like you!"

Grindelwald waved his hand irritably, took a deep breath, and tried to contain his emotions.

He retracted his previous evaluation of this girl, and he felt that even teaching a pig who could do magic might be easier than the stupid little girl in front of him.

For two full hours, according to Grindelwald's original plan, he had already taught Elena at least three or four simple and effective little magic, and could start some follow-up lessons, not like now......

"I'll say the last, the last time! Empty your brain, Elena Kaslana! When casting a spell, all you need to do is send a wish to [open] your spell! Got it?! You can't even do a little magic flow with a single lockpicking spell, and you'll be able to drop out of Hogwarts in five days!"

Yes, two hours have passed, and Grindelwald and Elena are still stuck in the initial teaching session, how to successfully release a complete lock-picking charm.

"But it doesn't make sense, Mr. Gellert. ”

In fact, Elena had already understood the problem when the second attempt at the spell failed, not in the gestures and pronunciation, but in her mental inability to accept it.

If we subdivide the logic of magic in this world, we can actually divide it into two large sections, the result-oriented chaos black box, and the logical self-consistent order derivation.

As Grindelwald said before, the key to successful spellcasting is that wizards need to know what they are going to do.

Elena's problem wasn't that she didn't understand what she wanted to do, as a time-traveler from the afterlife, rational thinking was an imprint ingrained in her soul - she knew too well what she wanted.

The lockpicking spell first appeared in Africa, and the spell comes from the West African Hikadi symbol, but it is unclear who originally invented it.

However, when the spell was brought to England by Elton Essric in the 17th century, it quickly became the most popular lockpicking spell in the wizarding world, and was a very basic spell in the first year of Hogwarts School of Witchcraft and Wizardry.

"You told me before that this spell works by opening doors and windows that are locked and not protected by magic. But we all know that the principle of locking doors and windows mainly comes from the physical barrier of the lock cylinder. ”

Elena glanced at the iron-faced Grindelwald and said quickly, "But in fact, there are many reasons for door locks, door locks, chains, deadbolts, composite locks...... Even with all kinds of strange closures, how can the spell accurately express my wishes without understanding the inner workings of the door lock?"

"That's the power of magic, you just have to ......" Grindelwald took a deep breath and tried to squeeze out a smile.

"I know magic is powerful, but you still haven't answered me, since there is a spell, it must follow some kind of rules that can be understood. ”

"As a primary spell, the lock picking spell can't have active thinking, so why can it be judged that it should use push, pull, lift and pressure to close to achieve the effect, and even, on what basis does it judge the definition of [open] and [off]-"

Elena swallowed, plucking up the courage to repeat her confusion once more.

"On" and "off" are not an accurate definition of natural existence, they are things that are judged by the subjective factors of the human brain in a specific context and situation.

For example, concealment can be seen as either closed or open, with the exception of old-fashioned locks, composite locks are opened in batches, and even if some of the necessary conditions for [opening] are [closed], then there will be a logical conflict.

According to the logic of the traditional lock-picking spell, it seems to point directly to the result - the door lock is opened, and then the whole step is completed by autonomously pushing backwards.

This kind of idealistic situation of inverted cause and effect obviously cannot be fooled by the power of magic.

At least Elena can't get around this hurdle from the depths of her heart, after all, the spell derived from it is not just as simple as unlocking, Cú Chulainn's piercing deaththorn spear can be derived in batches according to this logic.

"Enough!"

Grindelwald slammed the table, and finally stood up flawlessly.

"Regarding this issue, we will discuss it next time, it is just a basic lock-picking spell, you must reverse the creation principle and magic knowledge of the entire spell before you can successfully cast it?!"

After a long communication, Grindelwald also clearly understood the reason for the girl's failure to cast spells, Elena is different from most modern wizards, in fact, this half-breed little girl is closer to those magic explorers in ancient times - the solidity of their own beliefs, or the degree of stubbornness, can even affect the mature spell system in turn.

Undoubtedly, even Albus Dumbledore didn't realize that the little witch named Elena Kaslana needed more than just the way the spells were cast in the textbooks, she needed a theory system for the entire wizarding world to form the causes of all these spells.

In fact, Grindelwald was very familiar with Elena's mindset, because these are the confusions faced by a wizard who is beginning to try to create new spells.

As a top wizard who created and improved dozens of complete spells, Grindelwald was no stranger to it—such quarrels and discussions reminded him of the days when he first spent time with Dumbledore in Godric's Hollow, England.

It's just that this kind of thinking is too advanced for a child who has just stepped into the wizarding world. ”

Grindelwald panted as he looked at the girl in front of him who was frightened by his roar, slightly distracted.

Realizing this, Grindelwald could even predict that the difficulty of his magic teaching in the next few days would rise by at least a big notch.

Maybe he should sort out by himself first, what spells he can accurately say the complete magic theory, and the corresponding magic knowledge must be reprepared.

"Well, let's change the spell first. Before the invention of the lockpicking charm, most wizards preferred to use the Explosion Charm, which used their magic to create a small explosion......"

"It's not as subtle, but it's easy to use. However, this spell with some lethality is much more difficult than the lockpicking charm, and if I'm not mistaken, you won't learn it until at least your third year. ”

Grindelwald shook his head, his wrist slowly arcing through the air, and continued, "The spell isn't complicated, Bombarda, but I guess you'll probably need to imagine what an explosion is......"

The old man's tone was a little interested, obviously not holding out much hope.

"Well, anyway, I'll try it first, Bombarda......"

Elena shrugged her shoulders and didn't dwell on it any longer, obediently imitating Grindelwald's gestures and pronunciations, pointing her wand at a corner of the room.

A dazzling pillar of red light lit up from the tip of the girl's wand.

Rumble!
