Hogwarts: I'm Harry's older cousin

Chapter 342, Section 336: I have about twenty here.

What's the deal with this Fiery Curse?

Fiendfyre is a formidable spell even in the realm of dark magic. Durmstrang, who is generally quite tolerant of dark magic, lists this spell as forbidden, let alone teaching it to his students.

Moreover, he had found it very strange from the beginning. Apart from the little girl named Granger and Longbottom, why did the other three fourth-year wizards at Hogwarts start with dark magic?

He told me to use the strongest spell, but he didn't say to use dark magic. I originally thought it would be something like petrification or pulverization, or at most a raging fire.

The result was a series of unexpected and innovative black magic spells, including thunderous explosions and the like (Divine Edge Without Shadow). Now, they've even created Fiery Blade.

Only the three unforgivable curses remain unreleased.

This made Grindelwald wonder if Hogwarts had changed its rules and introduced a course on Dark Arts?

If he knew that every member of the disciplinary group knew at least some of the three Unforgivable Curses, he would definitely be certain that Hogwarts offered a course on Dark Arts.

"Kid, your dark magic is quite impressive."

With a wave of his hand, Grindelwald snatched control of the 'Fiendfire Dumplings' from Harry. Looking at the infinitely compressed Fiendfire inside, he sincerely praised Harry. When Harry was his age, he had only barely reached the level of controlling Fiendfire, far from being as free and unrestrained as Harry.

He truly blossomed when he was about to graduate from seventh grade.

What he didn't know was that Harry's Defense Against the Dark Arts and his Dark Arts were equally impressive. It's just that most defensive spells are only so-so in terms of offensive effectiveness. You can't expect the Patronus Charm to summon a Patronus to fight for you, can you?

Well, Harry's Patronus (the silver gorilla) might actually be a good one now.

Or do you use a protective spell to deal damage?

For example, casting a buff on yourself and then crashing into someone... Hmm? With Harry's current physique, that's not impossible.

Harry's attempts to regain control of the Fiendish Twister all ended in failure.

Grindelwald's seemingly simple operation is actually quite complex. The situation is complicated, and Grindelwald is able to do it because Fiendfire is one of his most proficient spells. Anyone else would not be able to do it.

With a wave of his hand, he dispelled the fierce flames, and with the elegance of a gentleman, Grindelwald seemed to be in a much better mood.

Now only you are left.

His gaze lingered on the last man, Dudley: "If you can achieve the results that satisfy me, then I will teach you for a holiday. If not, then you can go back to where you came from."

Dalit Grindelwald flashed what he thought was a hearty smile: "Professor Grindelwald, shall I begin now? Aren't you going to set up some magic or something first?"

"This castle contains magic that I set up before. Although it's not as powerful as your school, Hogwarts, it's not so easy to destroy."

Grindelwald was unconcerned about Dudley's linguistic advantage; he only wanted to know how Dudley intended to demolish his castle and how he couldn't withstand the onslaught.

"Since you're sure, that's good. Hermione, Harry, you all should get ready."

Unlike Grindelwald, the others believed Dudley's words wholeheartedly and immediately began casting protective spells on themselves.

"Protect them all"

"As solid as a rock"

"Enhanced Ironclad Curse"

Those high-level protective spells were thrown at them as if they were free, and in no time, everyone had countless layers of buffs stacked on them.

Grindelwald watched their actions expressionlessly, while his evaluation of their dark magic defense rose even higher.

Then Dudley slowly pulled two black box-like objects out of his pocket.

Something looks familiar; I feel like I've seen it somewhere before!

"This is.??!!!"

Grindelwald's pupils contracted slightly, as if he had remembered.

"Professor, this is my most powerful spell."

Dali picked one up and tossed it up and down.

"TNT explosives!"

With a solemn expression, Grindelwald named the black box.

TNT is a powerful explosive. Theoretically, 1 kg of TNT explosion can produce 4.2 million joules of energy, enough to move a 100 kg object 420 km.

As a wizard who has a deep understanding of Muggles and even knows about round bullets, how could he not know the power of these things?

But he was immediately refuted by Daddy as soon as he finished speaking.

"Professor, this is not TNT; its name is CL-20."

Dudley patted the black box, making Grindelwald's eyelids twitch.

"Has that group of Muggles changed again?"

Grindelwald immediately understood that the TNT he remembered was a thing of the past, and if it were a new type of explosive, its power would definitely be stronger than TNT.

"Yes, this is currently the most powerful explosive besides nuclear bombs, with a yield two to three times that of TNT."

Dudley picked up another one, opened the black box in his hand towards Grindelwald, and casually made up a story: "This is also my strongest magic."

What remains cannot indeed be called magic, but strictly speaking, it isn't either.

If I had to put it that way, was it technology or magic?

Nadali also possessed physical skills and magic.

"Do you think their destructive power can be compared to any kind of magic?"

Undoubtedly, some exist, but very few; at least most wizards cannot do it.

He had witnessed the power of TNT before; even among spells, few could rival it. Most importantly, it didn't consume magic. If the black box the opponent possessed was two to three times more powerful than TNT, then spells comparable in power would be even rarer.

Back when I first saw the round bullet, I was amazed. Muggles, who were always looked down upon by wizards, had actually developed to this extent. Faced with such a weapon, perhaps a wizard with profound magical power could escape by apparition, but most wizards did not have the ability to apparition, and even those who did could only achieve cross-border travel.

"Do you think my magic can move this castle?"

This situation is like the Fourth Holy Grail War, where the master set up numerous traps in the hotel, turning it into a magical fortress, waiting for his opponent to come and challenge him. But unexpectedly, Kiritsugu Emiya, that guy, showed no martial ethics and directly planted explosives in the parking lot, completely undermining his opponent's defenses.

Weapons manufactured by modern industry, once seen, must be acknowledged by even the most disdainful wizards.

Ordinary protective magic is unlikely to withstand the explosion of explosives.

"There are only two. It shouldn't be a big problem."

"Three, four, five. I have about twenty here."

Dali then pulled out a whole bunch of black boxes from his pocket.

Grindelwald: "."

Why do you, a wizard, carry so much explosives around all the time?
