Hogwarts: Bourne Returns from Warhammer

One word can help you solve the problem.

Bourne and Newt were both smart men, and they immediately understood why the old wizard was sad.

On the one hand, it is a solid proof of the overall weakening of the wizarding community.

On the one hand, there are some wizards in the UK who have fallen so far that they have to rely on "hyping" history together with Muggles to make a living.

Moreover, this kind of thing has been going on for at least a hundred years, and during this period, countless magical items have been circulated and countless Statutes of Secrecy have been violated.

For this old man who has carried the burden of the wizarding world on his shoulders all his life, no matter what the outcome, Dumbledore would actually feel frustrated.

Fortunately, Dumbledore was not a person who was consumed by internal friction. After solving the mystery, he quickly focused his attention on some urgent and necessary matters.

The old professor waved his hand, and his desk returned to its original tidiness, leaving only the "golden apple" that was identified as harmless.

"Horace and Severus have already told me that you have been successfully selected as a contestant for this year's Hogwarts Potions Championship. This was determined based on the final examination of the Summer Potions Special Training Class. It is fair and just. I would like to congratulate you first."

"Thank you, Headmaster," Bourne replied. He had actually expected this, so it wasn't really a surprise.

Dumbledore went on to say, "I also heard from Hagrid that you reached an agreement with Aragog, the king of the eight-eyed giant spiders in the Forbidden Forest, to move the basilisk out of the Forbidden Forest. Since you went to London to find Newt, I guess you also wanted to learn from him the application of the 'Untraceable Extension Charm' and the construction of a micro-ecosystem suitable for magical animals, right?"

Bourne was stunned.

Because what Dumbledore said before was indeed what he thought, but he had not actually thought about the issue of "constructing a micro-ecosystem".

There was nothing to hide about this matter, so he said directly: "Yes, Headmaster. But I didn't think of 'micro-ecosystem construction'. Does this kind of space transformation need to consider these things? Is it true that using the 'Traceless Extension Spell' alone to create a large enough space to meet the necessary elements such as air, water, and food is not enough for a basilisk to survive?"

Dumbledore shook his head.

"Sure enough, you also ignored this problem." The old wizard smiled and said, "In fact, I also studied the 'Untraceable Extension Charm' a little bit when I was in school. At that time, I was just like you. I lacked knowledge in this area because there was no introduction to this aspect in the existing books in the Hogwarts library-"

Then, the old wizard talked about why he wanted to study the "Untraceable Extension Spell" at that time.

At first, he wanted to provide a better and more spacious living environment for his pet Phoenix Fox.

Later, he discovered that Fox didn't care where he lived at all.

Because if this magical animal, which can Apparate at will in Hogwarts Castle, feels uncomfortable living there, it can travel to any place in the world at any time.

In this respect, the Fire Phoenix Fox has some similarities with Ryan, who was raised by Bourne and has the bloodline of the mythical beast Zouwu.

(Perhaps because there is a part of cat-kneazle blood in his body, recently, in addition to wandering around, Ryan has also taken to resting in cardboard boxes - he actually found some new cardboard boxes for himself from somewhere and piled them under the bed in Bourne's dormitory...)

Later, the reason why Dumbledore studied the issue of "micro-ecosystem" when studying the "Untraceable Extension Charm" was because he had considered a problem when he was in school.

That is, can the magic items created by casting the "Untraceable Extension Charm" be used to raise magical animals in large numbers and for a long time?

He was very curious whether such a space could accommodate some extremely dangerous dark magic creatures, such as the Pentapods, the Haunters, and the Dementors - these were not born naturally, but were the result of magical experimental accidents, or were evil dark magic creatures deliberately created by dark wizards.

“——For this purpose, I have made many attempts and obtained some results, but the results are not very satisfactory.

I discovered a rule: in a space with the 'Untraceable Extension Charm' applied, some magical items without life characteristics can indeed be placed without restriction, but creatures with magical powers are not suitable for long-term survival in that environment. "

Upon hearing this, Bourne and Newt both felt a little strange because they could both give counterexamples.

Bourne asked first, "But, Headmaster Dumbledore, you should also know that there is a store in Diagon Alley that sells tents cast with the 'Stretching Charm'? Moreover, many wizards' homes have used the 'Stretching Charm' in the past. It seems that there have been no reports of wizards becoming unwell due to living in such a space?"

Newt's question was more direct: "Yes, Professor, the magic suitcase you gave me, although many magical animals have come in and out over the years, some have lived in it for a long time. For example, there is a kappa in this box right now that loves to eat cucumbers every day. It has never gone out even once since it came in. It doesn't want to go out even if you ask it to. It has been in the box for decades."

In response to the two students' questions, Dumbledore waved his hand calmly, and a yellowed notebook appeared on his desk.

"First of all, whether it is a tent with a traceless extension charm, or the extra space created by a traceless extension charm in wizarding families when the law allowed it in the past, wizards will not stay in it 24 hours a day. That is just living, not living in it for a long time."

Dumbledore first answered Bourne's doubts, and then answered the questions of another student, Newt: "Newt, your suitcase is actually modified by me using the 'bag'.

However, it was not made when I was a student at Hogwarts.

It was only later, when I became the Transfiguration Professor at Hogwarts and gained some authority over this great school of magic, that I was able to build a 'micro-ecosystem' for that suitcase.

The most critical part was that I used the professor's authority to reduce a large part of the freely allocated living space. Then, I put the missing space into the suitcase opened up by the Traceless Extension Spell -"

As he was about to say this, Dumbledore tapped the yellowed notebook on the table with the Elder Wand, and the notebook turned into a huge sketch that covered the entire desk.

This sketch shows in detail all the steps how Dumbledore transformed a "bag" (Note: a bag specially used to catch magical creatures, which can suck in magical creatures that do not resist strongly) into the briefcase that Newt Scamander carries with him today.

"——Wizards, like magical animals, are creatures born with magic. Every breath we take and every movement we make is actually related to magic. If we are trapped in a folded space transformed by the 'Untraceable Extension Charm' for a long time, both wizards and magical animals will be unable to adapt. Over time, we may gradually become weak, and there may be a lot of irreversible damage to our bodies."

Dumbledore said calmly.
