Turning a corner, Gretel's head suddenly had a few more question marks.

A few steps away on her desk, Miss Otter was frowning, flipping through an ancient document that looked extremely obscure.

In front of him were stacked several ancient documents that were also full of traces of time.

The top one is Professor Tom Riddle's "The Dangers of Runaway Spells".

On closer inspection, as Gretel expected, all the books he didn't find were honestly lying in front of Hermione Granger.

Gretel silently walked up behind Hermione and found her watching Summary of the Investigation into the Camp County Anomalous Magical Riot.

Miss Otter looked really distressed, gnawing her fingers and pulling her hair, and the light in her eyes disappeared.

Gretel stood for several minutes, but finally decided to speak up.

After all, looking at Hermione's bitter and hateful face, it didn't look like she could get out of the tip of a bull's horn in a short time.

Although he didn't want to have anything to do with the Salvation Squad, he couldn't allow the special leave to be wasted.

"It's too early to read this, if you're willing to listen to it, I suggest you start with The Theory of Magic, An Overview of the Ancient Theory of Magic, and The History of Ancient Magic."

Hermione was startled by the sudden sound, and when she turned around, she saw Gretel's eyes staring at a table of documents.

His cheeks flushed, and he stood up suddenly, and said embarrassedly, "Well, I'm sorry, I asked Terry Bout about the content of your class."

I've heard that you guys have a history of magic at night, so I thought I'd read the book recommended by Professor Quirrell first.

I didn't mean to take these books away, you can take them right now if you need them. ”

Seeing Miss Otter's helpless look, Gretel finally pulled her eyes back from the literature.

"The books in the library are for public use, and although I do need them, you borrow them first.

If you don't mind, maybe we can watch it together. ”

Gretel shrugged, "You see, there are so many books here, but we only have two pairs of eyes combined. Of course, if you mind, I can come back and borrow it later. ”

"Of course, oh no, I mean I don't mind you reading it with me, no, I mean you can take the book with you if you need it, I don't understand what it's mentioned anyway."

Hermione looked a little frustrated, and for the first time she thought she might not be the best student at Hogwarts.

"It's not that you can't understand it, it's that you lack a basic knowledge structure, and the books recommended by Professor Quirrell are not meant to be read by people who don't have enough knowledge of magical configurations.

If you really want to learn, like I said, you can start by looking at the theory of magic, which is the basics.

After you have basically figured out the theory inside, you won't have a clue when you read this book. ”

In Gretel's sincere eyes, Hermione blushed and nodded, silently pushing the books on the table to the seat next to her.

"Then I'll give you back these books, and I'll go find the "Overview of Ancient Magical Theories."

Seeing the little girl leave happily, Glitter smiled and shook his head, not planning to take the book with him, so he sat down.

When Hermione returned with the book, she saw a high-spirited teenager writing a book.

Under the illumination of the light, the dark brown and black hair looks like a waterfall streamer, and the eyes that are close to the hair color shine like a pearl of the world.

In order not to disturb Gretel, Hermione quietly took her things and sat down at another desk where no one was around.

Coming into contact with the theory of magical configuration modification for the first time, Hermione had a lot of questions when she read it.

I wanted to go back and ask Gretel, but when I turned around, I saw that Gretel was meticulously taking notes, and it didn't look like he had time to deal with her.

I had to silently write down the questions in my own notes and ask for advice when Gretel was resting.

But the doubts don't go away, they only accumulate more and more, until the doubts accumulate enough to affect the reading, and Hermione looks up at Gretel again.

This time, Gretel didn't take notes, but raised his wand as if he had gained something.

"Don't," she tried to stop.

Mrs. Pince has a rule that all young wizards are forbidden to use spells in the library to prevent damage to the books, and those who violate the rules are arrested and handed over to their own headmaster.

But as soon as her voice came out, her mouth was silenced by the silence spell.

Looking back, it turned out to be Mrs. Pince.

Hermione gasped in surprise and silently mourned for Gretel.

Unexpectedly, she did not see Mrs. Pince go up to stop her, but instead crossed her arms with admiration in her eyes.

The only action was to enchant all the bookshelves around Gretel.

"Shhhhh

After casting the spell, Mrs. Pince did not put down her wand, it seemed that she was planning to rescue Gretel at any time.

Gretel sketched a modified magic configuration in her mind, the wand in her hand like a pampered child, and the joy filled almost the entire space.

The tip of the staff was light, and it looked extremely elegant, reminding Hermione of the grand pianist she had seen with her father.

That elegance comes from the self-confidence in the bones, and confident people have always had an indescribable, but the same calmness.

Gretel first projected a spell configuration that Hermione was familiar with.

It was the armor amulet, she recognized, she had studied it carefully before Gretel came.

But Gretel didn't stop, completely outlining the configuration, but he didn't stop his movements.

As if you don't have to think about it, you can push the node with magic.

Hermione covered her mouth nervously, for fear of disturbing Gretel, after all, the literature she had just read not long ago recorded many casualties caused by modifying the magic configuration.

She had forgotten that Mrs. Pince, afraid that she would disturb Gretel, had just cast a silence spell on her.

Unlike Voldemort's armor and body protection, Glitter did not choose to move the nodes outward, but pushed the nodes at the edges as much as possible inwards to make the configuration tighter.

After the node reached the predetermined position, Glitter used the armor again, and the operation was exactly the same.

With Gretel's actions, there were as many as eight armor guards that had transformed into carapace in the air.

As Mrs. Pince's breathing became rapid, Gretel leaned against the identical carapace-like armor.

No one needs to explain, Hermione also understands, Gretel wants to connect these armor talismans together through nodes to form an all-round protection without dead ends.

The stacking of nodes often means that they are out of control, so wizards are willing to choose to put a few more layers of spells and try not to leave dead spots for the enemy to attack.

Mrs. Pacings and Hermione looked nervous, and Gretel's movements were full of ease.

Because the panel had already given a hint when he conquered the configuration, the only thing needed now was to cast it step by step.

[Enchantment (unnamed): It forms an all-round protective barrier around the caster, and attacks on either side will be evenly distributed in the other seven directions, which is an extremely powerful talisman spell. 】

Compared to the original [Armor Protection: Build a wall around the caster that cannot be seen by the eye, resist and reflect simple spells], it lacks the ability to reflect simple spells, but greatly enhances the protection function.

According to Gretel's estimate, when he has a sufficient supply of mana, it will no longer be a dream to resist Arvada.
