People are in Hogwarts, and werewolves block the door at the beginning.

Harry and Ron didn't answer.

They, like the rest of the students, were staring at Lupin with rapt attention.

Looking forward to his response.

"Okay. Sirius happens to be away."

"There's a warm-up person next to me." Lupin said with a smile.

"That can't be true, sir!" said Ernie Hufflepuff cautiously.

"What do you think, little ghost?" Peeves blew out a wet raspberry in dissatisfaction.

"Of course it's true," Lupin shrugged. "If you spend any time with him, you'll definitely know that he's a great helper."

Peeves spun triumphantly in the air.

Hermione narrowed her eyes; she and Professor McGonagall agreed on the matter regarding Peeves.

Hearing Lupin say this, my already low impression of him became even lower.

"Let us keep going," said Lupin.

So they continued downstairs, through the foyer, the hall, and out the castle gates.

The sky, which had been gloomy, has now cleared up.

The sunlight passed through Peeves' body and formed a small dot on the ground.

Soon, Peeves, who always played pranks when eating and drinking, noticed this.

He bit his thumb, and his body expanded like a cartoon character, forming a convex lens as he floated.

The focused light soon appeared on Lupin's back.

However, until they reached the Black Lake, Lupin's back did not seem to be burning.

"What's going on?" Peeves narrowed his mischievous black eyes, gasping for breath and returning to his original state.

Lupin stopped abruptly and turned around. "The answer is simple. I cast an armor charm on myself in advance."

He looked at the student, "But I'm not saying this out of any knowledge of Peeves."

Swish!

A stone flew out of Peeves' hand.

Without looking back, Lupin grabbed it with his left hand.

"like this."

"Could it be!" Ron grabbed Harry excitedly, "You have eyes on your back."

Lupin nodded, "You could say that."

"Compared to some magical animals that have super speed, wizards' magic has a strong lag."

Everyone looked at Hermione and Basil.

Word of their performance in Herbology and Transfiguration had spread throughout the school.

Lupin smiled and said, "I think you have seen it too."

"They often attack you from unexpected angles or beyond your ability to react."

"But wizards can be the victors of the magical world, so there is naturally a way to solve this weakness."

"This is the spell I want to teach you in this class - the Extrasensory Charm."

Chapter 174 A Classroom Lost of Order

"It's an interesting spell."

"It's not something that is taught in the curriculum for students of your grade at Hogwarts."

"But I think it is necessary for you to learn." As he said this, Lupin easily dodged the angry cane attack from Peeves behind him.

Upon hearing the two key words "their grade" and "Hogwarts won't teach this", some careless students immediately perked up.

Harry raised his hands in agreement. "Why is it funny?"

Lupin winked at Harry. "The interesting thing about the ESP charm is that as you become more proficient with it, it reveals more abilities to you."

"Skills?" Ron also followed suit.

"It is more active than other spells, and is closely integrated with the wizard's mind and body. It is more of a way to exercise the senses than a spell."

"When you first start using it, you'll have a 360-degree view."

“That is, you can see everything up, down, left, right, front, and back.”

"Once you get used to it, you will find that everything in your field of vision seems to slow down, as if it is stagnant."

"At this stage, you can only deal with sudden sneak attacks and take the initiative in the duel."

"But for magical creatures with super speed, your body's reaction is still relatively lagging behind your vision."

"Then comes the final stage. When you become as proficient in using it as breathing, you will find that your nerve reflex speed will slowly increase, gradually surpassing the limits of the human body."

"Sir, what stage are you at?" Terry Boot of Ravenclaw was very excited, as if the thirty-year-old great wizard and his white moonlight had lost their virginity.

Lupin touched his nose, "Phase Two."

"So," he dodged Peeves' sneak attack again with a helpless look on his face, "could you please stop targeting me?"

"In my eyes, the peanuts you throw are as slow as a snail."

"Don't forget, you are the teaching assistant today."

"So," Peeves said with an evil smile on his broad face, "my target today is these little brats?"

"They used that damn clairvoyant spell you taught them to dodge?"

He spun in the air excitedly and rubbed his hands together again, "You better hurry up, I can't wait!"

As soon as he finished speaking, he started to take out "weapons" one after another from his tuxedo.

Moldy peanuts, bread, slingshots, catapults, bows and arrows, boomerangs.

They were all suspended in the air, and Peeves's sturdy little hands were stroking them one by one, as if he was playing a piano.

All the students looked at Lupin, looking at him with anxious eyes.

In Britain, where Quidditch is popular, they all instantly thought of the use of this spell.

Besides, they don't want to have rotten and smelly food on their faces.

However, Bagir was just yawning in boredom behind him.

There's a reason why the ESP, a spell that sounds so useful just by hearing its description, has never been added to the curriculum and no Quidditch player has ever specifically learned it.

The three stages mentioned by Lupin should actually be described in a more accurate way:

Stage 1: Casting a spell still requires the chanting of a spell and the waving of a wand.

Phase 2: Casting requires only the spell.

Stage Three: Casting spells to get rid of spells and wands.

In fact, no matter which stage, it will enhance nerve reflexes.

However, ESP is easy to learn but difficult to master, and most wizards can only linger in the first stage.

Therefore, it is of no use in Quidditch, where magic is not allowed.

Moreover, in the first stage, the spell lasts for a very short time, and it takes a long time for the human brain to get used to this full range of vision.

Unless it is cast beforehand and you are used to it, it is not very practical in a magic duel.

Only suitable for hand-to-hand combat with cold and hot weapons.

Most importantly, it's not very useful to Baqir, who has keen senses.

The 360-degree field of vision is a function that his 'Golden Eyes' inherently possess.

The method of training the senses using the supersensory spell was not suitable for him.

But it always felt like Lupin was spreading this spell directed at himself.

The clairvoyance spell is commonly used by the Werewolf Capture Team under the Department for the Regulation and Control of Magical Creatures.

It is a spell developed specifically for fighting against agile and dangerous magical creatures like werewolves.

A first-stage ESP spell is enough to make a wizard's nerve reflexes surpass a werewolf's.

While Basil was distracted, Lupin had already taught the spell and the corresponding way to wield the wand.

Hold the wand with your hand parallel to your eyes and chant the spell [Visible and Subtle].

Then pull it outwards to the limit, and twist your wrist so that the tip of the stick touches your forehead.

"Practice on your own first," Lupin said after demonstrating. "If you succeed, raise your hand and walk to my right, with your back to Peeves."

"Peeves, you can just attack the students on my right hand side at will."

On the grass beside the Black Lake, there was a sudden sound of [Observing the subtle in the deep cave].

Wand waving.

Ron was standing too close to Harry, and he instantly gave Harry a sharp elbow.

Draco lost interest in the wizard's magic, but this time he was serious and used too much force and almost poked his own eye.

However, it is clear that wizards with shorter wands have an advantage when casting ESP spells.

They just need to gently turn their wrists and the tip of the staff will just touch the center of their eyebrows.

For wands that are long, in addition to twisting the wrist, the elbow also needs to be pulled outward.

But Bagir's focus is not on this.

He suddenly remembered a book he had read in Ollivander's.

Most wands are between 9 and 14 inches in length.

Very short (less than 8 inches) and very long (more than 15 inches) wands also exist.

Owners of short wands often have character flaws.

Owners of long wands are often short in stature.

Bagel thought it was Ollivander making a dirty joke.

But after observing it now, he found it to be true.

For example, Harry is relatively short, and his wand is relatively long - 11 inches.

However, in Ron's case, this theory does not seem to be entirely true.

Willow, 14 inches, unicorn hair.

These are the data for Ron's new wand.

He does have character flaws, so it's no surprise that his wand is long.

But on the other hand, Ron was tall - relative to his peers.

Could it be that his character flaws are so great that they outweigh his height advantage?

Baqir did not think further.

Because Anthony Goldstein of Ravenclaw has raised his hand to indicate that he has succeeded.

This Ravenclaw supervisor and member of Dumbledore's Army in the original world line walked out of the crowd with a proud stride.

Shit! Are you trying to show off in front of me?

Naturally, Bagir could only raise his hand.

Next came Hermione.

This dealt a heavy blow to the arrogance that had just been aroused among the Ravenclaws.

Especially in the following dodges, Hermione and Bagel's movements were extremely small, and they always dodged just right.
