Hogwarts' "will" cannot comprehend new things that it has never encountered.

This is not difficult to understand.

For example, in the "Room of Requirement - Armory (Cold)", Elena can only see cold weapons and armor.

Even slightly outdated AK-47s, RPG-7s, M79s, C4s, M1938s… these modern individual weapons are nowhere to be seen.

However, things changed after she "created" a "Room of Requirement - Hot Weapons" room in the Room of Requirement.

Perhaps the Room of Requirement cannot provide weapons, but it can at least provide an empty room.

As Elena took out the toys she had obtained from the former Soviet Union from her chest, and placed them one by one in the newly appeared empty room, a new room option appeared in Hogwarts' Room of Requirement.

A place for storing wine can be called a wine cellar, and a place for storing books can be called a library…

The Room of Requirement not having hot weapons is not its problem, but the user's problem.

Of course, on the other hand, the Hyperion is not something unfamiliar to Hogwarts.

After all, the Hyperion arrived within the Hogwarts range last year.

Whether it's the waters, the air, or even the potato field, many places within the Hogwarts range have left traces of it.

"A Hyperion-class standard battle group consists of at least one to three 'Hyperion-class' nuclear magic hybrid space-air carriers, one to two cruisers, two to three destroyers, one frigate, and two supply ships… I want a large room where they can dock and refit."

Elena paced back and forth in front of the white wall in front of the Room of Requirement, unhurriedly.

She repeated her request softly.

This is not excessive, after all, the City of Incubus has similar huge spaces.

Since people call this place the "Room of Requirement," let her see where its limits are…

If it cannot even replicate another large room that exists in reality, then its "Requirement" is obviously mixed with a lot of water and conditions.

She narrowed her eyes, concentrated her thoughts, and hummed softly.

As for how to get the Hyperion in, it's too simple for a space-air carrier loaded with warp magic.

Dumbledore, as the Headmaster of Hogwarts, has the right to lift the school's "anti-space movement" restrictions.

This also means that, theoretically, the Room of Requirement could become their secret airport, of course, provided that…

It really has a way to conjure up such a large space.

"Elena."

When she turned around for the third time, Hermione suddenly said.

As with the previous dozen or so attempts, a very smooth door appeared on the wall.

Elena stopped, looked at it with interest, walked forward, grasped the brass handle, and opened the door.

A gust of cold wind rushed towards her face.

What appeared in front of her was not a room, nor a giant maintenance base.

They appeared on a semi-open terrace, with the vast and boundless sky and the sparkling Black Lake in front of them.

The Forbidden Forest in the distance was still covered with snow, presenting a pure white color, and in the far horizon, four or five birds leisurely crossed the sky.

"Eh?? Eh eh eh?! This is——"

"What were we just…"

"That's, the Astronomy Tower, right? I remember what it looks like!"

Surprised voices came from around the little wings as they curiously looked around.

After studying at Hogwarts for more than a year, apart from Elena, the remaining three little witches roughly recognized their current location at first glance:

Next to the Hogwarts Astronomy Tower, an unknown castle tower, facing the same direction as the Headmaster's office.

As expected—

Elena's eyes flickered, without much surprise.

Now, only the last small verification experiment remains.

Elena did not choose to explain anything first, but instead drew out her wand and pointed it at the flat, open forest clearing not far away.

Without any spells, all the magic power in her body gathered in an instant, transforming into an incomparably powerful magical force that rushed forward, directly hitting the open space, making a deafening roar, splitting the open land in front of the Forbidden Forest, and stirring up dust all over the sky.

Three, two…

Elena counted silently in her heart, before she could even count to one.

Suddenly, a series of messy, melodious sounds of windows opening rang out around her.

"Tsk, what a pity, so it's not a complete mirror world after all…"

Elena shrugged with a look of disinterest, put away her wand, and carefully listened to the voices around her.

Then, Elena turned around without hesitation, opened the "room door," and led the little wings back to the eighth-floor corridor.

Fortunately, she didn't cast a spell directly at the Headmaster's office just now—if she could find it—otherwise the first school-wide dinner after the Hogwarts Christmas might have turned into a memorial service.

As for now, she has an alibi by returning to the eighth-floor corridor.

Undoubtedly, the Room of Requirement has its own unique "clever" logic.

Under normal circumstances, it will open up some hidden space and make the decorations inside as consistent as possible with the user's ideas.

For example, in the original records, when Harry was looking for a meeting place for the DA, there appeared various books, magic practice props, and even the broken magical looking glass that had appeared in the Dark Arts Defense Professor's office during the Triwizard Tournament era; and when Dobby was looking for a place to put the drunken Winky, there also appeared a bed just right for the house-elf to sleep on and hangover potions…

And when the requirements faced by the Room of Requirement are too difficult, or the internal storage space cannot match the user's requirements.

It will present another form, or rather its true core form—

"This is a door to anywhere."

Elena closed the writing board in her hand and said with certainty.

"It's not just conjuring up a location, but as much as possible letting us go to the places we want to go. Perhaps it has some magic, such as providing empty rooms to cater to some new scene requirements. But the core principle is actually a special magic door."

"And if my conjecture is correct, then there is a very simple way to verify it…"

She glanced at the somewhat dazed little wings, who seemed to want to run to the window and look out, and raised her finger meaningfully.

"Are you ready? We're going to walk right into the trap——"

"Eh? What does this mean…"

Hannah looked at Elena with a puzzled expression, trying hard to get her head to turn.

On the other side, Hermione and Luna obviously thought of something, and looked at the white-haired dumpling with hesitation.

This white-haired dumpling wouldn't be…

As if to answer their doubts, Elena turned back and walked back in the corridor.

"I want to go to a place filled with portraits of past Hogwarts headmasters…"

She said softly and clearly, "It's best if it's a place filled with portraits of past headmasters, and also a place where you can conveniently raise a phoenix…"

After three round trips.

That smooth door appeared in their sight on time.

"Well, if I guessed right, then maybe we've developed an amazing function of the Room of Requirement."

Elena stared at the doorknob and gave a smile to the little witches behind her.

Then, she grasped the brass handle and pulled it open violently.

What came into view was a beautiful, square room with strange sounds.

And on the walls around the room, there hung a dozen or so portraits of wizards and witches who were dozing.

Along with the appearance of that soft, familiar light, she suddenly raised her voice and shouted triumphantly towards the front.

"Surprise! Hey! Are you two looking for me?!"

In front of her.

By the window of the Headmaster's office.

Two old wizards were frantically squeezing at the window, looking outside.

Hearing the greeting from the "little angel" behind them, the two turned their heads abruptly.

They saw that the oak door that was originally at the entrance of the Headmaster's office had suddenly turned into a smooth birch door at some point.

Elena, and three other little witches who stayed at Hogwarts for Christmas, filed in and appeared in the office nonchalantly.

And through the door behind them, one could barely see a magical tapestry of a giant beetle-infested troll beating up a small wizard.

"From now on, the Headmaster's office is a secret room——"

After Luna walked into the room, Elena closed the door behind her, and then opened it again and looked outside.

Just like all the rooms they had previously entered and exited, what now appeared outside the door was not the spiral staircase outside the Headmaster's office, but the deserted corridor on the eighth floor.

In other words——from now on, the Headmaster's office and the Room of Requirement overlap.

As for whether this phenomenon will lead to irreversible locking, that is not her concern.

With the initial survey of the Room of Requirement completed, the next thing should have been for Dumbledore and the others to participate in and jointly promote the follow-up.

Besides, Elena came to the Headmaster's office for another thing.

"By the way, Professor Dumbledore…"

About a quarter of an hour later, she finally finished introducing the records about the "Room of Requirement".

Elena cleared her throat, took the warm water handed over by Hannah, and drank it all in one gulp to moisten her dry throat.

During her introduction, the two old wizards were unexpectedly serious, and they listened to their explanation very attentively.

Apart from the occasional supplementary explanations from Hannah, Luna, Hermione, and others, it was as if these two old wizards did not exist in the room.

In fact, even if Dumbledore vaguely knew some information about the Room of Requirement.

But most of it was limited to "knowing", and the detailed records and surveys shown by Elena and the others were the first time.

If these were all the content of Elena's sudden attack today, Dumbledore felt that it would be okay.

Anyway, the little witch's magic spell eventually exploded outside the castle, and taking the time to cast a recovery spell before dinner would be enough to return everything to its original state.

However, Elena would not forget her other purpose for this trip.

"You must remember that I just said," her gaze turned to Dumbledore, "Last night I went to the Room of Requirement alone, and I also looked in the mirror—you should know, it's the legendary Mirror of Erised, the very interesting one."

The Headmaster smiled faintly, and the firelight flashed quickly across his half-moon-shaped eyes.

"Of course," Dumbledore said gently, "So you plan to temporarily 'borrow' it, or have you already borrowed it?"

"Not borrowing, I found a more suitable place for it, and the reason I brought this up is mainly——"

Elena shook her head seriously, raised her finger to correct, and said sweetly.

"If you want to look in the mirror later, then you may have to submit an application… My current plan is to store it as a new 'SCP object', so I hope… 'Pope' can persuade the Headmaster of Hogwarts to donate it."

Dumbledore raised his eyebrows——meaningfully, thoughtfully, and curiously looked at Elena.

"Well, of course, that's not impossible."

The old wizard said softly and gently, his eyes slowly swept across Elena's chest.

"But before that, I only have one question, what does a more suitable location mean?"

"City of Incubus."
