The students under the podium began to whisper, wondering why they suddenly needed to learn this spell.
Pansy's face was filled with deep nostalgia. She still remembered the novel experience when Malfoy took her to see the dementors.
Ron in the seat just wanted to say something, but shut up wisely. These days, he was trained very painfully by Moody.
"Haven't all the dementors disappeared?" A student asked Ron's thoughts.
"Yes, this is a reason not to practice." Moody replied patiently with a hoarse voice.
"But I also have reasons to practice."
"For example, we don't have definite evidence that the dementors are extinct, just in case." Moody tapped the wooden table in front of him a few times with his wand.
"Practicing this spell will also help you learn to control your emotions."
Whether it was an illusion or not, Harry felt Moody glaring at him with one of his penetrating magic eyes.
"And..." the teacher lengthened his end.
"You all know that today's wizarding world is not peaceful." Moody said in a hoarse voice.
"The Dark Lord may rise again at any time, and the power of the Death Eaters will spread and spread. At that time, our communication will be greatly disturbed, and the way owls transmit information will be very dangerous."
"Once it is intercepted, it will fall into a very passive situation." Moody's expression became more serious, and the magic eyes turned more frequently.
"And after learning the Patronus Charm, we can use them to communicate. After encountering an enemy, we can control it to disappear."
"Of course, that must be after mastering a more advanced technology. I can't reach it now, but I can give you an example." After Moody finished speaking, he immediately raised his magic wand , pointing to the high ceiling.
"Call God to protect you!"
Silvery gas rose from the tip of Mad-Eye Moody's wand, then condensed into shape.
It was a silver cheetah with a ferocious face, stepping in the air, staring at all the students with sharp eyes, as if it wanted to penetrate people's hearts.
It is in line with his character of being keen on arresting black wizards and helping justice.
Strong and flexible.
It is worth mentioning that the left eye of the cheetah has a deep scar running from top to bottom, which is so eye-catching on the silver-white body.
The form of the patron saint will change with the change of the owner.
But not all.
The patron saint's four legs are very flexible, and there is no sign of injury, unlike the owner who is lame.
Both Gryffindor and Slytherin students looked at Moody's Patronus enviously.
Because very handsome.
And at this moment Moody's nose, missing a large piece of flesh, trembled and he spoke.
"In order to complete today's demonstration, I specially asked an old acquaintance of mine, his skills can be achieved, enough to support long-distance control."
"Shacklebolt?" he called out the door.
As soon as Moody finished speaking, a silver-white lynx soared into the air from the door of the classroom, jumped in, and rushed into the classroom.
Attracted everyone's attention.
Then, with an elegant posture and sparkling lights, it landed lightly on the entire desk, and looked at the students around it with its sly eyes.
It caused the students to scream in surprise.
It is also a feline animal, somewhat similar to Moody's Patronus, with the same sharp eyes.
Perhaps this is some kind of commonality among fellow Aurors
"Hello, Alastor." Lynx raised its paw, opened its mouth wide, and greeted Moody with a loud, thick and slow voice.
"Hello, Kingsley." Moody also said, manipulating his patron saint.
"Please allow me to introduce myself first." Lynx turned around and faced the students in the class.
It waved its furry silver paws at the students again in an extremely humane manner.
"My name is Kingsley Shacklebolt. I used to be Mr. Moody's subordinate, and now I am an Auror at the Ministry of Magic."
Lynx introduced herself to everyone.
"I still have work and time is limited. Let me make a long story short. The Patronus Charm is a difficult but very practical spell, not just limited to the purpose of resisting dementors."
"Everyone here has also seen that I am not here. The most common way for wizards to communicate is to rely on owls to deliver letters, or stick their heads into the fireplace and project images."
"The former is not safe enough and takes a long time, while the latter is quite troublesome."
"Well, it's a bit dirty. I don't think any girls would be willing to talk to others and make their faces dirty, right?" Kingsley added.
The girls in the audience were all amused by his joke.
"Okay, everyone, goodbye, I hope you have a good study, I still have tasks." Kingsley's words were quite brief, after all, he was just a person invited to demonstrate.
"Everyone can start practicing. Before that, we can also look at the use of the master."
"As far as I know, there is a student who has mastered it well." Moody's eyes cast on a female student.
"Miss Parkinson?"
Pansy heard him call her name, stood up from her seat, and walked onto the podium without haste.
"Call God to protect you!"
Pansy raised his wand.
With a coquettish cry, a silver kitten gradually condensed into shape from the silver-white smoke. With its head raised, it paced back and forth in the classroom proudly and gracefully.
Then Pansy retracted his wand, and the cat turned into silver smoke and gradually disappeared.
"Pretty skilled Patronus Charm, twenty points for Slytheringa." Moody began to applaud.
The Slytherin students also applauded spontaneously, but the Gryffindor's applause seemed a little weak.
Especially Ron, his hands didn't move at all.
"It's just hilarious," he said.
"As far as I know, the Patronus Charm can reflect a person's character to a certain extent."
"So the shape is different."
"It may be a magical creature, such as a phoenix, such as your headmaster, Mr. Dumbledore. Of course, it may also be an ordinary animal that can be seen everywhere."
"What we can know is that the ability of the patron saint is different from the form, but the ability displayed has nothing to do with the form."
"According to records, the most powerful Patronus is a rat, and the wizard named Ilyus stopped an army of hundreds of dementors."
The students below exclaimed again.
"So you don't have to be upset that your Patronus isn't beautiful or handsome enough."
"You can go to the library to borrow "The Curse of Defense and Deterrence", which contains more profound answers." Moody tapped the table with his cane, reminding the students.
