Harry replied: "Because of the instability of magic?"

This is a phenomenon that is widely found among young wizards.

The most famous one is Seamus Finnigan from Gryffindor, a guy who is proficient in turning all kinds of spells into blasting spells. The magic power in his body is not stable enough. During the casting process, it will follow Seamus' most instinctive emotions. The slightest fluctuation will cause it to explode directly.

As Seamus grew older and his magic became more stable, these incidents became less frequent.

This is also one of the important reasons why the Ministry of Magic prohibits underage wizards from using magic without the accompaniment of adult wizards after leaving school.

Don't be afraid that the little wizard will be seen casting spells by others.

At worst, the memory cancellation team can work overtime.

The original intention of this rule was to worry that if a young wizard rashly cast a spell without the accompaniment of an adult wizard, it might cause serious and irreparable harm to itself.

Scamander nodded. "That's why."

"Has Miss Granger ever failed to cast a spell?"

"I mean, even if you have learned a certain magic, if you are not careful, it will change into something else."

Hermione asked hesitantly, "Like Seamus Finnigan?"

The first person she thought of was that person.

Scamander was confused.

Seamus was not included in Dumbledore's introduction.

"A classmate of Gryffindor." Harry explained simply, "Whatever magic he used before would easily turn into an explosion."

"Hermione is different."

"Maybe, sometimes I fail to learn some magic, but it has never been like that."

Scamander understood and nodded. "Then Miss Granger should be very suitable for learning Apparition. If her magic power is stable, there won't be any problems."

They sat down at the Hufflepuff table.

The badgers who remained in Hogwarts cast curious glances at the older, unfamiliar senior.

"Breakfast at Hogwarts tastes just as I remember." Scamander took a sip of soup and sighed.

Compared to the others, he spent a shorter time at Hogwarts, only six years.

Wait until after dinner.

"Do we really want to start now?" Scamander and Harry walked to the side door of the hall and opened it a crack.

Outside the auditorium, the wind and snow were blowing violently.

"The weather isn't very good now," he muttered, "Wait until noon, when it's warmer..."

Harry waved his wand.

The spell was cast, falling on Scamander: "Mr. Scamander, wizards don't worry about this kind of weather."

Scamander sighed, "It's a good thing I didn't agree to Dumbledore's request three years ago to come and be a professor at Hogwarts."

He followed Harry out.

No wonder last night, after Harry asked him to learn “Apparition”, Dumbledore and that cold Severus both looked at him with pity.

A student who is so studious that even professors have a headache.

Outside the courtyard.

The outlines of several snowmen were covered by the snow, and Crookshanks was patrolling the territory with a group of cats.

Scamander pulled out his wand. "Apparition is a simple spell."

"I heard from Dumbledore that you all learned the Patronus Charm. If you have learned such a difficult spell, the Disapparation Charm will be even easier."

"When using the Transfiguration Charm, you need to follow the 3D principle."

“The first step is to focus your awareness on your destination.”

As he spoke, Scamander pointed his wand and a circle appeared ten meters away.

"Now you can use that wooden ring as your target."

He exhaled a breath of hot air and continued, "Then, make up your mind to move the wooden ring a little bit, let the years you want to go fill your brain, and then spread to all parts of your body."

"Finally, don't be nervous. What you are going to do next is just a transformation in dimension and space."

Scamander paused for a moment and said, "3D, purpose, determination, and calmness."

"I think you all have all these."

"Mr. Potter, would you like to try it alone?"

Harry nodded, stared at the wooden ring, raised his wand, and chanted the spell: "Apparate."

With a snap.

He disappeared from where he was and reappeared in the wooden ring in the blink of an eye.

Scamander waved his wand, and a few strands of hair that had not yet fallen to the ground and a piece of clothing fell into his hands.

"Very good, Mr. Potter." Scamander was surprised, "You can do this on your first try."

Although……

This time the spell was not successful, there were still body tissues and belongings left. But this was only the first time, and I had just finished introducing it.

Harry walked back and waved his wand to restore the robes to their original state. "It doesn't seem to be very successful."

"It's been very successful." Scamander shook his head. "When I first practiced, I lost half of my body."

"Miss Granger, would you like to try?"

Hermione nodded, raised her wand a little nervously, and chanted the spell.

Apparition!

With a snap, she disappeared, but not completely.

The body below the knees remained where it was, and the rest of its body failed to appear in the wooden ring, but floated to the stone statue fountain in the courtyard.

Scamander quickly cast a spell to reverse the magic effect.

"This is such a terrible experience, I'm going to have a nightmare." Hermione rubbed her face.

The body passed, but the feet did not.

Scamander shook his head: "You are both excellent."

"Mr. Potter, your biggest problem is that you are not proficient enough. If you try a few more times, you should be able to succeed."

As he said that, he turned his head and looked at Hermione: "Ms. Granger, you are not calm enough, you are a little too nervous."

"Relax a little."

Harry and Hermione are both smart people, and Scamander is also a good teacher. Although he sometimes stutters, he is very patient and teaches until nine o'clock in the evening.

Scamander was called away by Tina, who finally couldn't bear it anymore.

She couldn't bear to use her husband like this.

Apparition is indeed not difficult.

In just two days, Harry had completely mastered the art and could come and go freely. Dumbledore personally served as the examiner and set a test for Harry, asking him to Apparate to three locations: Diagon Alley, the Potter mansion in Godric's Hollow, and Nurmengard.

Harry passed them all easily without leaving out any part of his body, not even an eyebrow.

Hermione's progress was a little slower.

After Harry learned the "Apparition" spell, an advanced version of the Disapparation spell that could allow people to Disapparate, she also learned it successfully and passed Professor Dumbledore's test.

Snape has not appeared during this period.

Until the last day of December.

Harry and Hermione are leaving.

Snape just appeared in Dumbledore's office.

"Here you go. This is the potion that Albus asked me to brew for you." Snape took out a pocket and put it on the table. "You've caused me a lot of trouble, Potter."

Dumbledore looked at him in silence.
