So I changed the principle of the Patronus Charm a little.,But this should also be considered the accepted setting of the HP fandom.。

I suddenly found that the little Odang teacher is still very qualified. (But is it really okay to let her teach others?) I always felt that she would bring all the students badly...... ）

Having said that, in fact, Xiao Ao's talent guardian form is really easy to guess, and I have hinted so obviously......

==================================

Wand 3 (upright): Learn with help.

、

Hogwarts Library

、

"I said Opal, you can actually read these books in the common room, can't you?"

Trying to avoid being kicked out of the office by Mrs. Pince and only muttering in a whispered tone, Draco felt that he didn't understand why Opal was wasting his time in the library.

Obviously, during this year's Christmas holiday, Opal complained to him that she had read all the interesting books in the Hogwarts library except for the forbidden books.

[Draco ......]

Putting down the book in his hand with a slight cry, Opal glanced at the young man beside him, [If you get bored, just leave.] I remember your Quidditch looks like you've been training this week, right? ]

Why bother buzzing in her ears, if it goes on like this, the Slytherin captain Quidditch will cry to death to show her - because if you do it directly, you will definitely lose.

"Opal, you're driving me away!"

The deep Turkish blue eyes were full of accusations, and the grief on Draco's face at the moment really made Opal shake off goosebumps.

[I'm waiting for someone.] ]

Rubbing his temples in frustration, Opal began to reflect on whether he had made a mistake in not even calling Pansy and Blaise to avoid trouble - at least they could distract Draco a little.

"Who?"

[Someone you know, Draco, anyway.] ]

Pigeon's blood-red eyes turned abruptly, glancing closer to the aisle, Opal closed the book in his hand and the notes on the side, and then stood up, [Let's go. ]

"Huh? Aren't you ...... waiting for someone?

Stunned by Opal's sudden move, Draco glanced a little strangely in the direction Opal had just looked - of course, he didn't notice anything.

[Keep up.] ]

After dropping this sentence, Opal picked up the book path and walked out of the library, and then came to the location of the room on the eighth floor, and after three rounds, he opened the wooden door full of aristocratic atmosphere that suddenly opened on the wall, [Okay, come in.] ]

"It's good to say something on the road, why don't you come to a place like this?"

Although he complained quietly, Draco was very considerate when he realized that Opal had no intention of entering the door, and walked into the room without asking.

Then about 6 or 7 seconds later, Opal walked into the room and closed the door casually: [Alright.] Harry, Hermione, you two can come out. ]

"Huh?"

Draco froze for a moment, but then he was almost startled by the two suspended heads that suddenly appeared in the room - the bodies of those two people also appeared with fluctuations like water ripples, "Scarhead, why are you ......?"

He even brought a Muggle seed with him......

"Yo, good afternoon Draco."

Folding the cloak and tucking it into his pocket, Harry scratched his trademark tousled hair and turned to Opal, who was pursing his lips and smiling, "Seriously Opal, I've always wondered how you could spot me and Hermione. ”

[The cloak can isolate body temperature, breath, and body, but it can't isolate sound.] ]

Pointing to his ear, Opal shrugged, [You know, I've always had a keen sense. What's more, Hermione accidentally bumped into the bookshelf, and if you can't hear it, you're too underestimated. ]

“……”

Draco silently turned to face the wall - Opal you were born to hit him, and now he doesn't have any doubts about it.

"Listen to Harry...... Can you teach us the Patronus Charm? ”

It was Hermione who spoke, and although the contact between her and Opal was not usually infrequent or hostile due to Ron's relationship, it was the first time that such a peaceful close encounter made her feel a little overwhelmed - after all, she still remembered the scene when Opal beat her mercilessly in the second year.

"Patronus Charm?"

Draco turned to Opal with a frown, "Opal, you're going to teach Gryffindor this spell?" You ......"

[There's a reason for Draco.] ]

Tilting his head, Opal's expression at the moment looked extremely innocent, and there was a hint of caution, [In fact, the tutorial of this spell has entered this semester's academy tutorial - I don't think you can expect the so-called 'order' of the Ministry of Magic to really restrain those Dementors who act completely on instinct?] ]

If the Dementors were that easy to deal with, their faction wouldn't be "Chaos Evil". You know, this thing is the third most hated creature in the world for unicorns - the first is the dragon, and the second is the night.

I think when I first met Philnet and his entourage in Opal, the secret realm of the lake, I almost followed my instinct and attacked. Although Yeji are dark creatures that can be tamed, their strength attributes are more similar to those of natural predators for unicorns.

But Philnet is a special case. Because he is a hybrid of Nightmare and Nightmare, and his bloodline is closer to Nightmare, and he always restricts his own Nightmare aura, Opal is closer to him - but Opal's subordinates are still able to control themselves, but they don't have a good face, after all, this is the nature of magical creatures.

In fact, the relationship between magical creatures is definitely not as black and white as outsiders think, and it is the upper and lower levels of the food chain or the nature of each other, and the magical creatures are natural enemies when they meet, but as long as they are rational, then it is usually difficult to really fight - speaking of which, this is also thanks to the Gaia contract set by the original son of Gaia for magical creatures, this self-contained contract is directly witnessed by the planetary consciousness, and as long as the planetary consciousness still exists, then all magical creatures will not violate.

"No wonder."

Draco thought of it himself when Opal reminded him of this, but he still felt a little depressed - Opal was a Slytherin student! It really feels a bit ...... that the person who came to teach Gryffindor is Harry Potter with the aura of "Savior"

[Ravenclaw has Cho Chang, Hufflepuff has Cedric, and Slytherin has our Chiefs.] But you can't expect Gryffindor to think of this on their own, can you? ]

Seriously, if it weren't for the fact that the magical creatures in the Forbidden Forest all continued their contract with Hogwarts, and that taking care of Harry was a pact she had with Dumbledore when she was in school, she would have been too lazy to meddle with things.

"Yes...... But I had to teach Gryffindor. Opal has worked so hard for you. ”

Although he muttered to himself that Opal's politeness and detachment from others would lead to the name of a Hufflepuff student, Draco also knew that this was not the time to care about such things—after all, Opal would bring him with him to the Requirement Room, which meant that he was also the one who wanted to learn the Patronus Charm.

“……”X2

Hey, did you two despise Gryffindor so much to your face when the two of them didn't exist?

The corners of Harry and Hermione's mouths, who had been in the background for a long time, kept twitching, especially Hermione, who was almost about to have a seizure on the spot. However, after getting along with Harry for most of the summer, he barely understood a little bit of Slytherin's behavior pattern, so although the forehead corner was also ungentlemanly, he still suppressed Hermione first.

However, it is necessary to use the sound of coughing to remind oneself of one's existence, which is still necessary.

[Harry, you and Hermione take a look at these two books first, just read the above spells and the principles of the Patronus Charm, and then memorize the spells, and I'll give you half an hour.] ]

After pulling out two identical copies of the book he was holding and throwing them to Harry and Hermione, Opal turned to look at Draco, who was about to speak, [I know Draco, you already know that spell, so you read the book first, and then you will be with Harry and Hermione later.] ]

Therefore, the inheritance of the noble wizarding family is far better than that of those Muggle and civilian wizards, at least the entire Slytherin can even the first-year students say the Patronus Charm in its entirety, unlike the students of other houses who have to memorize it alone.

Speaking of which, the school age at Hogwarts was eleven years old, and the previous preschool education seemed to be a blank, and she hadn't heard Riddle mention it. Fortunately, the aristocratic families had special tutors, and Muggle wizards had Muggle schools to attend before the Magical Riot if they had families, but those civilian wizards also had Muggle wizards in orphanages......

After suddenly thinking of a possibility, Opal's head instantly drew a black line of first-class school - she really sympathized with the Hogwarts professors, the senior students might be fine, but the junior students' papers ......

"Okay, I got it."

Draco nodded, took Opal's hand, and sat down next to him to flip through it.

Anyway, he didn't have to worry that Opal would give him some useless books, after all, he knew very well that although Opal was usually lazy and could push things when he encountered them, it was also because she had more important things to do. It really involves responsibility, and Opal is definitely the one who is more responsible than anyone else.

Not to mention, he had heard the roar that morning, and it was clear that Opal was using the teaching of the Patronus Charm to defend against Dementors - the position of head of the academy was not so easy to sit in, but if that person was Opal, Draco felt that he could still easily accept it.

If you replace it with someone else...... Hum!

Half an hour was fleeting, and compared to Harry, who had barely finished reading it before the time limit, Hermione had already finished it early and had already started practicing there.

"Expecto.Patronum!"

With the wave of Hermione's wand, the tip of her wand did not react at all, and a very light layer of silvery-white mist could already be seen spewing out from the back.

[Alright Hermione, let's stop and rest for a moment.] ]

Opal glanced at it, knowing the level of talent of the Gryffindor Jack-of-all-trades lady, and waved her hand to stop her further common sense.

"Why not?"

Hermione, who was sweating on her forehead because of the excessive consumption of magic in her body, finally stopped the wand in her hand and looked at Opal instead, "I've been working hard to think about those happy things." ”

It would be absolutely deceitful to say that she was not depressed, after all, she was also very conceited of her qualifications, but at the moment, even the mist could only summon so little, which was really not at all comparable to Opal, who could directly summon the Guardian God of the flesh.

[As we all know, a Patronus is a collection of positive forces that advocate for what the Dementors covet most - hope, happiness, and the hope of life.] And because it's just a collection of power, it's not as desperate as a human, and there's no way for Dementors to use this to devour damage. ]

After briefly explaining the principle of the spell, Opal looked at Hermione, [But Hermione, who told you that summoning the Patronus Charm must be a happy memory?] ]

"Huh? Isn't it? ”

Hermione raised the book in her hand in some astonishment, "But the book is ......"

[The book also states that dark wizards cannot use the Patronus Charm.] ]

Opal rolled his eyes, [though I know that many of the dark wizards I know can use the Patronus Charm.] Not...... It also included several Death Eaters. ]

"How is that possible!" X2

Harry and Hermione shouted out immediately, unusually in tune.

[What's impossible?] The so-called black magic or white magic is just a different manifestation of the power attribute. ]

For the fuss of these two people, Opal shook his head helplessly, [Whether it is black magic or white magic, the premise of use is the user's emotions. Generally speaking, white magic emotions are more positive, while black magic emotions are more negative. However, this division is also very general, because many feelings actually have something in common. ]

“…… It's the first time I've heard of this theory. ”

Over there, Hermione had found a notebook out of nowhere, "But Opal, according to you, doesn't it take a happy memory to cast the Patronus Charm?" ”

[Of course not, the casting of the Patronus Charm is to put it bluntly, it just requires strong positive emotions.] It's just that for ordinary wizards, the feelings represented by happy memories are easier to manipulate. ]

Holding his chin in one hand, Opal shrugged his shoulders as if he had thought of something, [in fact, as long as the positive emotion is strong enough, then even if you don't have happy memories, you can summon the Patronus.] And the definition of the so-called 'positive feelings' is very broad, such as self-confidence, enlightenment, etc...... Both are available. ]

"In other words, if you have enough confidence in yourself, you can also summon a Patronus, right?"

At this time, Harry suddenly spoke, it was obvious that he did not doubt Opal's words, and even breathed a sigh of relief, "It's easy to understand it this way......

[Not really.] ]

Opal appropriately poured cold water on Harry, [If you summon the physical Patronus for the first time, because the form of the Patronus varies from person to person, it is usually easier to determine the form of the Patronus if it is a happy reminiscence. And the form of the Patronus is not static, it will change due to strong feelings. ]

"But it doesn't usually change, does it?"

At this point, Draco suddenly interjected.

[I don't know about the others, but my Patronus is changing.] Usually the first appearance of the Patronus should be a person's natural Patronus form, and then if the feelings are strong enough, the Patronus will change accordingly. ]

Opal shrugged his shoulders, [My Patronus was very vague when it was first summoned, but it could be seen to be a horse-like creature, but the second time it was summoned, it became ...... Such. ]

With that, Opal waved his wand, and suddenly the silver mist gathered into a silver-white python coiled around her body, and its blue eyes were watching the other three people in the room.

Although he doesn't particularly like snakes due to the Basilisk problem, after seeing Opal's Patronus, neither Harry nor Hermione can feel any "disgust" or "hate" related to it.

The ice is cold and gentle, and when you are gazed at by those blue eyes, you can even feel a restrained tenderness.

"It's beautiful......"

Harry reached out in fascination as if to touch it, but the silver snake swung its head away from Harry's hand and swam to another corner of the room.

Hermione and Draco had already begun to wave their wands and start practicing.

[Actually, whether you can successfully cast the Patronus Charm is very simple.] ]

After smiling and disbanding his Patronus, Opal looked at Harry's blood-red eyes with a faint warmth, [The point is on your realization. Because the Patronus represents your positive emotions, the stronger this emotion is, the more solid the Patronus will be. By the way, the most important positive emotion for me is...... Guard. ]

"Is that ......?"

After listening to Opal's words, Harry fell into deep thought—he always felt as if he vaguely grasped what Opal was trying to say, "I know Opal, I'll try." ”

[Alright, go practice, Harry.] ]

Opal winked at Harry, [Now I'm going to get back reading, Harry, you can practice with Hermione and Draco.] Hopefully, before dinner tonight, I'll be able to see your patronus. ]

Your statement that you don't have back pain when you stand and talk is really ...... Yali Mountain is big!

The three people present complained in their hearts.
