International students at Hogwarts

Chapter 10 The Nature of Spells

After coming out of the Potions classroom, Lu Ren went to the auditorium to have a simple but delicious lunch, and then he went straight back to the lounge, not to rest, but to make up lessons for himself.

There's no way, and he doesn't want to, but he can still handle it now. After a few days, he will need to use various spells, so what can he do if he doesn't know anything?Professor Snape's favorability must have plummeted, which is not good.

Back in the dormitory, Lu Ren picked up a tattered copy of "Standard Spells, Elementary" from the small desk. Although the Room of Requirement has some old books in better condition, Lu Ren deliberately picked out a copy with graffiti on it. Yes - Harry can get Snape's old textbooks and get a lot of cheats, there's no reason I can't.

The result is really not good...

This book is just a tattered old book, and the graffiti on it are also meaningless words. It seems that the old owner of the book has deserted in class.

However, after Lu Ren flipped through the "Standard Spells, Elementary", he was embarrassed to find that there were no cleansing spells and restoration spells in it!

This is very embarrassing!
"Standard Spells, Elementary" only teaches the nine basic spells of softening spell, cutting spell, unlocking spell, levitating spell, locking spell, repairing spell, repelling spell, illuminating spell and lighting spell.

Although there are only nine spells, they are all very practical little spells, and even if you learn one spell a week, it will take two months to finish it.Therefore, the arrangement of teaching materials in the magic world is still very reasonable.

Lu Ren thought about it for a while, and decided to follow the steps in the book to learn step by step. The first spell is you - the famous floating spell!
'The floating spell can make objects float in mid-air or slowly fly over.Gestures: Waving and bouncing.Spell: Wingardim Leviosa'

???

When I put a question mark, it's not me who has a problem but you who have a problem.

What the hell teaching is this!I don't understand it at all, it's confusing.This short sentence is the description of the method of casting the floating spell in the textbook.

incredible!How does this cast a spell!

"Calm down, Lu Ren, you have to calm down!" Lu Ren comforted himself, there is always no harm in trying, he took out his wand 'Floating Life', "Wingardim Leviosa!" At the same time His own arm also waved and shook with the spell, waved and shook.

However, it was of no use.The parchment in front of him was still lying quietly on the table.

"It seems to be the problem of the accent of the spell and the punctuation of the sentence." Lu Ren recalled for a while, remembering Hermione's teaching to Harry and Ron in the original book, "It seems to be Yuga-Dim Levi-O-Sa, to Can you make it a little longer?"

While muttering, he tried again according to his memory, but unexpectedly, the parchment really floated up from the table, hanging four feet above his head.

"Success!" Lu Ren was extremely excited. After all, this was the first time he cast a spell, a living spell, not a trick like blindfolding.

After the excitement, Lu Ren fell into confusion.Knowing what is happening and not knowing what is why is Lu Ren's current state.Lu Ren didn't understand why this piece of parchment could overcome gravity and float in mid-air.

The common sense of physics given to him by compulsory education told him that to make an object float in the air, it needs to give it a force that is opposite to gravity, but where does this force come from?Why can he just be equal to the gravity of the parchment?

And in the process of casting the spell, what role does the spell play? Why does the same word, replaced by a different sentence, make the spell effective?

A series of questions filled Lu Ren's head.

And these questions also lead to some questions, such as why spells must be pronounced in English, do French people need to learn English first to learn spells?Thanks to Dumbledore, I am able to speak, speak, read and write English fluently under the spell of comprehension cast by the greatest wizard at present. Other wizards in the magic world should not have such benefits. Then how do those French perform magic?Their accents are to die for!If the spell begins with h, the French can't pronounce it at all!

Confused, very confused.

Lu Ren cast the floating spell a few more times, and now he discovered something.

When he came to Hogwarts on the first day, he had sensed some special particles in the air, and these particles had caused the magic in his body to get out of control.Now he is used to the existence of these particles, and he can feel these particles at any time.

And when he cast the Levitation Charm, some particles escaped from his arm, and these particles flowed along the arm into the palm, and finally into the wand, and when they flowed out from the top of the wand, the vibration frequency increased significantly.This stream of particles eventually hovers under the parchment, providing an upward force that keeps the parchment suspended in the air.

"It's really amazing. Although some particles are lost in my body, I can feel that my body is spontaneously and slowly attracting particles from the outside world! Eventually, the particles in the body and the outside world will reach a balance, and this spontaneous behavior will stop. .” Lu Ren was very excited, he could now understand the principle of the spell.

Magic is nothing more than the use of a special energy in nature, and wizards are rare human beings who can feel the existence of magic particles.The wizard's use of magic is essentially the same as the photodiode's use of solar power to generate electricity.

The casting of the spell should be divided into three parts.

First, mobilize the magic of physical strength, funnel them into the palm of your hand, and transfer them to your wand.

Subsequently, the wand acts as an amplifier, amplifying the tiny magic power to a volume that can interfere with the existence of the outside world. The principle of the wand may be to allow particles to obtain higher energy.

Finally, output magic power to complete the goal.For example, apply a force to the parchment until the two forces balance.That's why the parchment first floats off the table and then floats in the air.Because the initial force is greater than its own weight, the parchment has an upward acceleration, but the force gradually decreases, and the acceleration also decreases, and finally the acceleration is zero.

Generally speaking, casting a spell requires a wizard to manually complete these three parts, but these three parts look simple, but in fact they are quite complicated. In actual combat, novice wizards may not be able to do such complicated operations, so the magic spell was born. .

The essence of the magic spell is similar to the functions already written in the program. Wizards can directly use the ready-made things as long as they call out the magic spell correctly and match the appropriate conditions.Similar to code.Of course you can write functions on the spot, but it’s troublesome, how fragrant is it to use the ready-made ones directly?
After understanding the principle of the spell, Lu Ren immediately became enlightened. The spell in "Standard Spells, Beginner" has lost the difficulty for him!
"Sure enough, you have to see the essence through the appearance!" Lu Ren was very proud, "I am a genius!"
