"Now, you understand the origin of his title of invincible Andros!"

In the classroom of the history of magic, looking at the Ravenclaw eagles with their mouths wide open and their faces full of disbelief, Terry said with some smugness.

"But is there really such a powerful guardian spirit in this world?" The unnamed Kitty asked with some suspicion.

"Not even Professor Dumbledore's Patronus is so powerful! Moreover, he also used a wandless spell. ”

"Merlin knows if it's true or not." Terry spread his hands, signaling that he didn't know about it.

"That's all I learned."

"Well, weakly ask, can anyone tell me what the Patronus Charm is?" Ike asked timidly, next to him a similarly confused Earl.

For the two of them from Muggle families, the Patronus Charm was a high-sounding but unfamiliar spell.

The second-year course doesn't mention this kind of spell, and there is no trace of it in the library collection, which is a kind of soul magic after all, and naturally Dumbledore has put it in the forbidden area.

William had tried to look for it before, but he couldn't find any of it.

"It's a very clever spell that requires an extremely strong infusion of positive emotions to be successfully released, and a successful Patronus spell can summon a concrete positive force, and that is your Patronus." Seeing that everyone was watching him, William immediately explained.

He had been practicing the spell for a long time, and naturally he didn't need to think too much about some of the most basic conceptual questions.

"It usually appears in the form of an animal, but unless you actually summon it, you never really know what your Patronus looks like.

Embodied Patronus often symbolizes your own character and outstanding soul qualities, and as far as I know, Professor Dumbledore's Patronus is a phoenix. ”

"Yes, not only that, but the Patronus Charm has a very long history, even dating back to ancient times, which is inferred from the remains unearthed in the jungles of Albania last holiday, with some frescoes and terracotta tablets." Terry also added from the side.

"And what is the main function of this spell, I mean?" Earl, who is not very talkative, also asks William his own question.

"Good question, Earl. The embodiment of a Patronus summoned by a successful Patronus Charm is the predator of many dark creatures, and is very resistant to the likes of Dementors or Voldemort, as well as some powerful Patronus that can even defend against evil dark magic. ”

"You know so much, William. I've heard that Dumbledore's Patronus can even withstand the Diamond Heart Charm! Terry continued to add what William hadn't said.

"If, this wizard, Andros, is really powerful enough to summon a giant-like patronus, I don't think there is much black magic that can help him, even if it is a death curse, it may not be impossible to be blocked." William boldly guessed how powerful a giant-sized Patronus would be.

"Do you believe this is true, William? Is there really such a powerful wizard ever existed? The eaglet asked William.

"Of course, because the greatest beauty of magic is that it is full of unknowns and uncertainties, and that means anything is possible.

In the long course of history, it is not impossible for such a powerful wizard to appear. ”

With that, William turned his head to look out of the classroom, where Draco and Pansy were already waiting, sensing William's gaze and waving their arms at William with some excitement.

"Okay, let's talk first, I still have something to do, let's go first."

"Or go find Malfoy?"

"Well, it looks like Draco and they should have taken care of the company's land." William nodded, then strode towards the door.

Terry on the side looked at William's back, and he was about to say something, but was interrupted by a few timid voices on the other side.

"Weakly ask, what is the Drill Heart Curse?" "Terry, what is the Death Curse?" ”

Earl and Ike, at this moment, they realized that they knew too little about the wizarding world.

"Just by the name, this is definitely not a decent spell like the Patronus Charm, they are all very evil dark magic .................."

................................................

"What are you talking about?" As soon as William walked out of the History of Magic classroom, Pansy asked William with some curiosity, as did Draco next to him.

They hadn't heard those words from Terry and William, so they couldn't help but be a little curious now.

"Nothing, something about the Chamber of Secrets and the Patronus Charm. Let's talk as we go? William replied succinctly.

The group then walked towards the kitchen on the first floor, and Draco and Pansy recounted the anecdotes of the past few days as William described to them what had just happened.

"Is there so much use for the Patronus Charm? William, you know so much! Pansy said abruptly.

"Do you think my Patronus will be a dragon?" On the other side, Draco also asked with some excitement, looking at his excited appearance, eager to release a successful Patronus Charm right now.

Dragon? Just because your name is Draco and like fire dragons?

It's not impossible, after all, there is no mention of Draco's Patronus in the original books, William thought to himself.

He felt that the little dragon in the original book was disqualified from using the Patronus Charm because he had taken the wrong path, so he did not summon the Avatar Patronus.

"In general, the image of the patron saint is those ordinary animals." William explained to Draco.

And when he heard this, Xiaolong's face immediately drooped.

"However, there are exceptions to everything, as far as I know, Dumbledore's Patronus is a magical creature, a phoenix, in addition to this, in the history of wizards, there is also the existence of this giant Patronus, have you heard of the invincible Andros?"

After both of them shook their heads, William was not ashamed to come in a wave of learning and selling, and scared the two little snakes of Slytherin for a moment.

"Cool! William, if you're going to teach me how to use the Patronus Charm, I can't wait to conjure up a concrete Patronus. ”
