A Brand-New Idea!

The Flash Charm brought Sean quite a surprise, and Hermione and Daisy were also amazed.

Of course, with Sean's current Spell Proficiency, the Flash Charm is not powerful enough. But once his proficiency increases and Sean can Wandless Casting, the Flash Charm will be one of the most powerful spells in actual combat.

The success of his first attempt gave Sean a lot of motivation, and in order to remember the feeling, he tried again.

It was a success again.

This time, he tried to set the flash distance to be shorter and consciously sped up his movements.

As Sean predicted, the required casting time was shorter this time than the last.

Just as Sean was excitedly preparing to do it again, Hermione suddenly stood up.

She covered her mouth, looking at Sean in disbelief, her eyes filled with astonishment and incomprehension.

"What's wrong, Hermione?" Sean asked, puzzled.

"You teleported!" Hermione's voice was sharp and excited.

Sean didn't react for a moment. He spread his hands out in confusion and looked at himself. "Yeah, and right in front of you, it worked twice—does something look wrong with me?"

"No, not this!" Hermione stamped her feet in disbelief. "You teleported! You teleported at Hogwarts!"

"Yeah, I teleported..." Sean answered instinctively, then froze on the spot.

He too opened his mouth wide.

All teleportation magic is prohibited within the entire territory of Hogwarts! The only exception is the Phoenix's innate teleportation ability.

Apparition, Floo Powder, Portkey —all of these are prohibited! Only the Headmaster can grant access!

Sean clearly did not have Dumbledore's permission.

He raised his wand in surprise. Although the casting time was long and the distance was short, he had indeed teleported inside Hogwarts twice.

Logically speaking, this is impossible. As an extremely powerful Magical Item, and built within Magical Grounds, Sean's magic could not possibly withstand it.

Then there's only one possibility... Sean's eyes lit up.

Don't forget, the essence of the Flash Charm isn't teleportation, but summoning...

Just as you can use a summoning spell like Serpensortia at Hogwarts without being hindered, the Flash Charm, which is essentially Summoning Charm, will also not be hindered.

This means that Sean can freely enter and exit all parts of Hogwarts, and no wall will hinder him.

Alternatively, he could lure powerful enemies into Hogwarts, where he would have a natural advantage.

What about the Room of Requirement? Sean immediately thought of the space he was in.

In Sean's understanding, the Room of Requirement might exist in two ways.

One is Mirror Dimension, and the other is a variant of the Undetectable Extension Charm.

This magical space, which incorporates many profound magical techniques, is a place Sean has always wanted to explore thoroughly.

Sean had a sudden thought: if he were standing on the Seventh Floor corridor, could he use the Flash Charm to directly enter the Room of Requirement?

Because, regardless of the true nature of the Room of Requirement, Sean is certain of one thing.

The Room of Requirement must exist only at Hogwarts.

It may just be a bare room, and then it will Transfiguration into whatever shape the user needs, but in any case, the Room of Requirement is definitely a space.

As long as there is space, the basic conditions for Summoning Charm are met. According to this rule, Sean can teleport into the Room of Requirement from outside.

The only potential problem is that when the Room of Requirement is not summoned, it may be hidden in another space that is not intertwined with reality.

Because the ghosts that can walk through walls have never inexplicably entered a room without a door on the Seventh Floor.

But perhaps I can use some method to pinpoint the location accurately...

Sean became excited; this was probably his initial motivation for exploring the Magical World —the unknown and curiosity.

He was genuinely curious about what Room of Requirement, in its most basic form, would be like if it didn't understand the user's feelings.

Moreover, this is not a useless exploration; the Room of Requirement is filled with a huge pile of... well, junk from Hogwarts over the past thousand years.

Perhaps you can find ancient curses, strange and wonderful items, and so on.

Moreover, Sean never forgot one thing: the Hogwarts Authority that Salazar Slytherin had mentioned.

Is one-quarter of Ravenclaw's power related to the Room of Requirement?

Sean had been suspicious for a long time, but he just hadn't found a breakthrough.

After telling the two girls her thoughts, Hermione immediately fell into deep thought.

"The Flash Charm is essentially Summoning Charm, so it makes sense that the restrictions at Hogwarts don't work on you, and your assessment of the Room of Requirement also has some merit..."

Daisy chimed in, "But there's a problem. The Room of Requirement could be hidden anywhere in Hogwarts, and the stone wall on the Seventh Floor is just a doorbell. If that's the case, your Flash Charm will be much less effective."

"That's right," Hermione nodded. "And there's another crucial point: how do you pinpoint the location? The essence of the Flash Charm is manipulating magic to outline the magical contours of the desired location. Magic can pass through walls, but it obviously can't automatically find its way—you might not be able to pinpoint the exact location. In that case, using the Flash Charm rashly is a very dangerous act. You might end up like those failed Summoning Charm, with the summoned creature getting stuck during the summoning process. Of course, this charm will cause you to be the one who gets stuck, and you might end up in a dark space that no one knows about."

Sean licked his lips. "You're right, but I really think my idea has some merit—of course, I won't try it rashly until I find a safe method and master the Flash Charm."

Hermione gave him a serious look. "I hope you don't do something stupid."

"Don't worry, I still value my life..."

Actually, if Sean were to unfortunately find himself trapped in an unknown, dark space, he would have a way to escape; he even possessed a tool that would guarantee his escape. Of course, Sean would feel it was a complete waste to use it in a situation like this.

Therefore, all actions should only be implemented after we find a better solution.

Since the beginning of October, the weather in the Scottish Highlands has become increasingly cold, and time at Hogwarts has been steadily progressing in this damp and biting chill.

The students were delighted that the Ministry of Magic did not send another Senior Undersecretary after Umbridge was dismissed.

Of course, the rules are much stricter than before.

In mid-October, another serious incident occurred outside. The details of the incident were concealed, and even Lupin could not find out more information. However, the level of danger exposed in the Wizarding World increased once again.

Now, let alone Hogsmeade Village, it's extremely difficult for students to even leave the castle, Dementor have begun to roam the covered bridges of Hogwarts.

Just a few days ago, an attack occurred in Hogsmeade, reportedly carried out by an Azkaban fugitive. Fortunately, the situation was resolved before it escalated.

The man wanted to use the Imperius Curse to control the owner of Honeydukes, then poison all the candies and give them to the students as gifts. The plan wasn't very clever— the Imperius Curse worked well, but the poisoning didn't.

Snape happened to be in Hogsmeade that day, and even walked into Honeydukes...

While it was strange that the perpetually expressionless, gloomy professor would walk into Honeydukes, Sean could understand— Daisy had pitifully told Sean in the hallway that she had run out of sweets because of restrictions, and when Sean took out his remaining pile of candy, he happened to see Professor Snape just turning away around the corner...

Anyway, it's just such a coincidence...

Snape smelled something was wrong as soon as he entered Honeydukes. He pretended not to notice and then used a gas Potions to indiscriminately poison everyone in the room except himself.

The prisoner who was hiding in the storeroom, foaming at the mouth, was arrested on the spot by Snape.

However, the candies contaminated with the gas Potions naturally had to be destroyed—it was said that when the Auror took the prisoner away, he seemed to have suffered quite a terrible torment.

After this incident, Hogwarts became more strictly controlled, and the patrols by Auror and Dementor were intensified.

However, without a new Senior Undersecretary, the students were not too depressed, and their studies and lives were still relatively normal—especially since Professor McGonagall even sent someone to help contact the parents of the students from the Muggle Family.

This made Sean feel that he could at least thrive in a healthy environment.

Inside the Room of Requirement, a colossal silver Fire Dragon, obscuring everyone's view, was soaring through the air. Daisy was displaying an astonishing talent for the Patronus Charm —she was now contemplating how to freely shrink and enlarge her Patronus.

Hermione also did well; she was able to summon silver otters to play around her.

Only Sean ran into trouble.

"Did I succeed...?" Sean held up his wand uncertainly.

After all his efforts over this period, his silver mist has finally evolved.

It grew from a small ball into a very large one, almost blocking Sean's view...

Daisy, the little genius of the Patronus Charm, recalled her silver Fire Dragon. She tilted her head and examined it for a while, saying uncertainly, "It seems much stronger than the previous mist, but it hasn't taken shape yet—I don't know, I don't know much about the Patronus Charm."

"You don't understand, so you summoned Fire Dragon on your first try, right...?" Sean's eyebrows twitched. This little girl's Invisible Versailles was quite infuriating.

Hermione put away her wand and came to the side, saying, "Perhaps you've already mastered it, but the emotion is still lacking?"

Sean shrugged after a moment's thought, "Maybe, but this fog seems pretty good, hasn't dissipated after all this time."

Daisy encouraged him, "With a little more practice, you should be fine. You'll definitely be okay."

Sean smiled and said, "That's what I think too."

At least there has been progress, and the progress is steady.

After practicing the Patronus Charm, Sean started fiddling with his Flash Charm.

Sean's progress with the Flash Charm was much faster. He had previously taken a Wit-Sharpening Potion, and with a lot of practice, his proficiency with the Flash Charm increased rapidly.

Now, although he can't Silent Casting yet, Sean can already teleport extremely quickly, and the distance has been greatly increased, now only a few feet away from the maximum distance of the Flash Charm.

"Point Apparition!" The voice had barely fallen when Sean appeared at the other end of the room.

The speed and accuracy are both good... Sean nodded with satisfaction.

Beside her, Daisy was pondering the technique of the Flash Charm, glancing up at Sean practicing every now and then, and occasionally biting her pen.

After Sean blinked again, Daisy muttered to herself, "Why can't he move long distances..."

Hermione heard what she said and explained, "Because your magic can't extend that far, inaccurate positioning will cause Blink to fail."

Sean also said, "The key to Blink is the precise landing point. If you extend it too far, not only will you be unable to outline the accurate magic outline, you won't even be able to find your own magic marker point."

Daisy nodded as if she understood, then asked in confusion, "But other Summoning Charm can summon creatures from far away."

"The Flash Charm is a variant of the Summoning Charm, and it's quite different from the regular Summoning Charm," Sean said.

"I see... So, is your modified Wingardium Leviofa a variant? I can make that too, and it's a bit different from the regular Summoning Charm." Daisy said, aiming at a dummy in the distance. As the spell finished, a calf appeared out of thin air and slammed into the dummy.

Sean scratched his head. "Strictly speaking, mine is a variant, because ordinary Summoning Charm don't have a location function..."

As he spoke, Sean suddenly froze on the spot.

Yes, location tracking. My modified spell has location tracking...

Long-distance positioning!

Seeing Sean deep in thought, Hermione and Daisy exchanged a glance: What has this guy thought of now?

At this moment, Sean's brain was working at lightning speed, not only utilizing his Spell Talent but also taking full advantage of the Spell Improvement Bonus from the Ravenclaw Set.

My Wingardium Leviofa was a success, which shows that Summoning Charm and long-range targeting can be perfectly combined.

What if I changed the spell rules for summoning the bison to the Flash Charm, and then combined them with the lock spell framework?

Do I summon myself to crash into the target?

No, that means the casting range would just be my own line of sight...

Sean's brain was working frantically. In his mind, the magical structure of the two spells was gradually revealed, and he began a frantic comparison.

"This isn't right... this isn't right either... there's a conflict here... the magic transmission here will be blocked..."

"Should we change the root word and then add the first step of the Flash Charm... No, it seems more accurate to replace it..."

"Replace the structure pointing to the bison with the summoning method of the Flash Charm, but don't replace the target grabbing of the Summoning Charm... Hmm? What if I reverse the incantation of the Wingardium Leviofa... Here, replacing the structure of the Flash Charm with a stable spell combination, that's something I'm very good at..."

After a long silence, Sean's tightly pursed lips finally relaxed a little, and a look of joy appeared on his slightly flushed face.
