Chapter 582: Confusion

Sean walked past here and came to Hope Cottage.

Mr. Owl didn't speak today, which was rare, but instead opened the door for him quickly.

In Hope Cottage, the fireplace was burning happily, and the wooden bookcase was rearranging itself from time to time, classifying Sean's books.

Sean knocked on it, and soon, the wooden boards rearranged, and a Pensieve was spat out.

Some silvery-white threads were surging, and Sean leaned over the Pensieve.

His feet left the ground in an instant...

He fell into the darkness again, falling into many memories.

"Ravenclaw's..."

When he broke away from the memory and returned to Hope Cottage, he was dazed for a moment.

He actually couldn't remember what Ravenclaw had left behind.

Hufflepuff's cup, Gryffindor's sword, Slytherin's locket... but what did Ravenclaw leave behind?

He picked up a silver thread, and the Sorting Hat appeared in his ear:

"Of course, of course, the diadem of exceeding wisdom, the cup full of sincerity, the sword called by courage—"

Ravenclaw left the diadem... but, why couldn't he remember it?

When he found this word, some associated memories also surged up.

But it always felt like it was separated by a layer of gray, hazy stuff.

He locked his brows tightly, raised his head, and Mr. Owl's portrait had moved indoors at some point, looking at him eagerly.

After being discovered by him, Mr. Owl's portrait quickly slipped outside the house again.

"Mr. Owl?"

Sean called out.

"Clever little wizard—"

Mr. Owl turned his back to Sean, muttered a sentence, and then remained motionless.

Sean stared at Mr. Owl for a while... Mr. Owl was too strange today.

But Mr. Owl clearly wasn't prepared to say anything, so Sean could only continue to recall Ravenclaw's diadem; could it be that he just forgot it?

To know this, there was a way—that was Occlumency.

Whether he was affected by some inexplicable magic or had forgotten, Occlumency could help him find more details.

Senior students had already left Hogwarts Castle in groups, and young wizards could be seen everywhere in the corridors, looking out the windows with envy.

Sean was holding the plan map—at the location of the staff room, a red exclamation mark lit up.

Below it was written in a line of runes:

【Professor Fuliwei, Undetectable Extension Charm】

This weekend, Sean could learn the Undetectable Extension Charm from Professor Fuliwei to support his production of Undetectable Extension storage items.

The Undetectable Extension Charm could naturally be learned from Professor Fuliwei, but what about Occlumency?

Sean knew that a wizard who could skillfully master Occlumency was an Occlumens.

Known Occlumenses include: Albus Dumbledore, Gellert Grindelwald, Voldemort, Horace Slughorn, Severus Sineipu, Barty Crouch Jr....

So, could he learn from Professor Sineipu?

When he proposed to Professor Sineipu that he wanted to learn Occlumency, how should he explain the reason for wanting to learn it?

While thinking, he had already walked to the place agreed upon with Professor Fuliwei—the staff room.

This was a room specially provided for staff to rest, a long room.

At its entrance were two talking stone beasts, the walls around the room were inlaid with wooden boards, and it was filled with mismatched old black wooden chairs.

The elderly Professor Binsi was also resting here, waiting to stand up and go to class next week.

Hmm... it had been like this for hundreds of years.

"Professor Fuliwei."

Sean knocked on the door.

"Come in, child."

The one speaking was not Professor Fuliwei, but a voice Sean was familiar with.

"Professor Marcus Maige."

Sean's pace quickened a bit.

"Learning the Undetectable Extension Charm requires a lot of patience."

Professor Marcus Maige was holding a cup of black tea, the steam swirling in front of her square glasses.

"Yes, that's right. Come on, little Green."

Professor Fuliwei pulled Sean in enthusiastically,

"I'm not surprised at all that you want to learn this spell, but, child, tell me, what is the Undetectable Extension Charm?"

"The Undetectable Extension Charm can expand the internal volume of an object without changing its appearance, and reduce its weight.

When casting, it often requires the use of a closed container and cooperation with magical materials to maintain the effect.

The principle is to achieve geometric volume expansion by reconstructing spatial dimensions."

Sean paused for two seconds and replied.

"Brilliant!"

Professor Fuliwei nodded with satisfaction.

"Then you should also know that casting spells privately without authorization is a major illegal act, and violators face the risk of imprisonment in Azkaban."

Professor Fuliwei said again.

Sean naturally understood; the Undetectable Extension Charm could keep the original appearance and size of the cast object unchanged, eliminating traces of spatial anomalies to avoid magical detection.

This meant that if not strictly controlled, large-scale illegal concealment by people would be seen everywhere.

It was not a good thing for the stability of the entire wizarding world.

"However, the Ministry of Magic's approval is fast."

Professor Fuliwei smiled and handed Sean an approval form.

This was quite surprising to Sean; after all, he hadn't expressed his willingness to learn for long...

Professor Fuliwei had deep experience in the field of charms, and under his guidance, even with only blue talent, Sean learned very quickly.

Before long, he mastered the knack of it.

"Undetectable Extension!"

As his wand waved, the inside of the paper box seemed to undergo a drastic change. If you reached a finger in, you would find that the paper box, which wasn't even as long as a finger, could actually swallow an entire finger.

【You practiced the Undetectable Extension Charm once to the standard of an apprentice, proficiency +1】

【Undetectable Extension Charm: Unlocked (1/30)】

Sean held the paper box, the corners of his eyes slightly carrying a trace of a smile.

With the panel, the only difficulty Sean had to face was basically time.

However, although Sean successfully cast the Undetectable Extension Charm, the paper box quickly returned to its original state, which was because there was no material assistance.

And the most important material for making Undetectable Extension items was the skin of a Thunderbird.

In the staff room.

The plan map ran out by itself, the sky-blue quill rustled, and wrote down another plan.

Looking at the various locations and folded plans on it, Professor Fuliwei was more or less stunned.

Then he laughed dumbly:

"Is this your plan for half a semester? Little Green?" ===== CHAPTER 583 =====
