Two Worlds: I studied at Hogwarts

Leaving Professor Snape's office, Moon went directly to the library on the second floor.

After he handed the borrowing slip to Madam Pince, the librarian gave him a suspicious look.

"This is a borrowing slip from Professor Snape?"

After reading the contents of the parchment, Madam Pince raised her head and curiously sized up Moon.

As a senior staff member of the school, she was very aware of the irreconcilable conflict between Gryffindor and Slytherin.

And the fact that the little wizard in front of her could get Snape's signature was a rare thing at Hogwarts.

"Yes, Madam, do you need to verify it?"

Moon stood beside her, looking at her with a warm smile.

"Verify? Absolutely not."

Madam Pince placed the borrowing slip on her desk and then walked towards the restricted section.

She was worried that the little wizards would impersonate the professors' handwriting to borrow restricted books.

But even the dumbest little lion wouldn't choose to imitate Snape's handwriting to borrow a book.

"Although I don't know why Snape would agree to lend you this book, you must remember to find a wide place when reading it."

As she spoke, Madam Pince handed Moon a very small, black leather magic book with a copper clasp.

On the title page of this book were two lines of small, gold-stamped letters.

《The Magic of Hidden Spaces: A Guide to the Undetectable Extension Charm》

"Reading this book requires finding a special place?"

Looking at the magic book, which was not even half the size of his palm, Moon's eyes showed a look of doubt.

He took the book and was about to open the copper clasp when Madam Pince immediately reached out to stop him.

"No, never open it here. Find a classroom or go out to the lawn, the weather is nice today anyway."

"Okay, fine."

Although he didn't know why Madam Pince would say that, Moon still planned to do as she said.

He knew that in the magical world, anything could happen.

Watching Moon walk out of the library with the book, Madam Pince heaved a sigh of relief, patting her chest.

"Luckily, I stopped him."

Moon didn't plan to read outside. The temperature had dropped sharply in the past two days, and studying outside was simply torture.

Fortunately, his spell practice classroom was also on the second floor of the castle, just straight ahead and a left turn out the door.

After having Bouncy find Mrs. Norris to borrow the key, Moon couldn't wait to open the book.

"Chirp ~" (So big ~)

The magic book, which was originally smaller than Moon's palm, instantly covered most of the classroom after the copper clasp was opened and the title page was turned.

Bouncy was originally playing with Mrs. Norris.

Noticing the sudden appearance of a large book in the classroom, both magical creatures curiously ran over.

It was also the first time Moon had seen such a big book.

He tried hard to close the heavy title page, and the magic book instantly returned to the size of his palm.

"As expected of a magic book recording the Undetectable Extension Charm."

Moon said curiously, then took off his shoes and reopened the magic book in front of him.

Because the area of the paper inside the book was particularly large, Moon had to stand on the book to study in order to avoid soiling it.

Fortunately, the text recording the spell content was not very large, otherwise Moon would have to spend a lot of effort just to read and turn the pages.

The author of this book was named Elinor, a space magic master more than 100 years ago, and also a wizard who loved to travel.

In addition to introducing the theoretical knowledge of the Undetectable Extension Charm, the book also introduced many ways to use the spell during travel.

Among them was how to use the Undetectable Extension Charm to make a suitcase.

This just happened to fit Moon's current needs.

After memorizing the spell and wand movement, Moon first closed the big book.

According to the contents recorded in the book, if you want to make a suitcase that can expand space, you must be proficient in this spell.

So what Moon could do now was practice the spell and become familiar with it as soon as possible.

But before that, he decided to first look at Professor Snape's original spell, and practice them together later.

Spell: Sectumsempra

Wand movement: Stand sideways, hold the wand tightly in your right hand, let your arm hang down naturally, then extend it forward at an extremely fast speed, while stabbing the wand towards the target as swiftly as a sword.

Precautions: Pay attention to speed and power, the movement must be clean and neat.

Counter-curse: Vulnera Sanentur

Wand movement: Hold the wand, get close to the injured area, use your wrist as an axis, gently touch the edge of the wound with the tip of the wand, then slowly and gently draw circles around the wound, from the outside to the inside, with gentle movements.

Remember: Do not use this spell lightly unless necessary.

Professor Snape's description was very detailed, and he repeatedly urged that this spell must be used with caution.

"A cutting-type magic, how could it be considered a dark magic?"

Looking at the content on the parchment, Moon felt that this spell, called Sectumsempra, was just an enhanced version of the Severing Charm.

After reading through the content once, Moon held the parchment in his left hand and waved his wand in his right hand to start practicing.

"Sectumsempra!"

When the movement became skilled, as Moon chanted the spell, the wand suddenly stabbed forward, pointing at the clay figure.

Clang!

Without seeing any magic effect, he only heard the sound of a sharp blade being unsheathed.

Then a deep crack appeared on the chest of the clay figure.

At the same time, the clay figure, which should have shown a crying expression, this time turned into anger.

Its eyes were wide open, as if accusing Moon of using bad magic.

"As expected of dark magic, it's much more powerful than the Severing Charm."

This was the first time Moon had caused damage to the clay figure with a spell.

In the past, spells cast on Snape would only make its face turn pale, or even cry.

But Sectumsempra this time caused substantial damage to it, and it couldn't be restored.

"It seems that I really need to use this spell less in the future."

After Moon finished speaking, he immediately cast a Healing Spell on the clay figure.

When the wound was smoothed over, the clay figure's expression returned to normal, but a very obvious scar remained on its chest.

"The damage of this spell is too great, I definitely need to use it less at Hogwarts, but it's very suitable in another world."

Moon had already provoked the Faithless organization on the Vena Islands, and he was worried that he would be discovered by their wizards before.

But as long as he could master this spell, Moon's ability to deal with group battles would be greatly improved.

After all, Professor Snape said when introducing this spell: The damage caused by Sectumsempra is related to the number of times the wand is waved.

It just so happened that Moon had mastered a set of wand-waving techniques of his own when practicing other spells.

In addition, the wand movement of Sectumsempra was not very troublesome, which gave him the ability to cast this spell quickly.

Especially since Moon was very talented in cutting-type magic.

Mastering Sectumsempra might really be able to play a role at a critical moment.

"I can find the giant squid to practice with, after all, its magic resistance attribute is high enough."

Although Moon decided not to use this spell on people at Hogwarts, the necessary practice couldn't be less.

And now the only object that could be used for practice was that big guy, Snape couldn't withstand the damage of this spell either.

After learning how to cast the Undetectable Extension Charm again, Moon prepared to leave the small classroom.

But as soon as he turned around, he found that Bouncy had already sent out a Christmas gift in advance.
