After exiting the class, I made myself through complex pathways of Hogwarts with intent on finding the Room of Requirement. After reaching the seventh floor, I looked for the tapestry of Barnabus the Barmy.

I remembered that across from tapestry was the entrance. I found Barnabus in the third corridor I tried, and across from it, was an empty stone wall.

Walking back and forth three times, furiously thinking, I need a safe place where no one can disturb me, to progress in magic. A small wooden door appeared, opening the door, leading me to a circular room, divided into different areas. A round table beside a fireplace with row of empty shelves.

Next to the table is a comfortable sofa type reading chair. As I sit on it, I feel my whole body relaxed. The chair is charming for sure.

Wanting to test the room's magic, I thought I really could use some information on Animagus magic. Right as the thought entered my head, I saw the Shelves filling up with rows of books. I summoned the first one from the stack. The age of the book could be felt as I ran my fingers across the cracks in the leather spine. Saw that the book was titled History of the Animagus, "Oh, this room is such a broken piece of magic" I thought to myself.

Though I can't practice it now, I don't mind adding the books to database.

I continued my experiments and tested the limits of the room.

[The room of requirement: It's the one thing that made me realize there might be more to the monsters than few descriptions in Books.

The room is an alchemical miracle that can cast magic on it's own. That's right. It can do the same magic that I believed requires a soul. Though it is still true. The room taps into the wards and schemes of Hogwarts through which it uses the Leyline under it. It basically powers itself from world's magic and It has Artificial intelligence, Rowena Ravenclaw managed to make an AI back in Medieval ages based on mind magic.]

"Avis"

The summoned birds attacked the dummy as I jumped to the side avoiding the colored rays of needle prick.

I soon started picking on the mannequins, I like to call them dummies. I run around the slowly moving dummies who are in a circular formation showing no gap. As they are dealing with the conjured bird like constructs, I attacked them with onslaught of spells but found that most missed except a single "Flipendo."

"Damn , I really have shitty aim."

So, I removed the aim from the process. As the first dummy bounced back , I moved on the gap formed and casted on slowing charm-Impedimenta with a wand on dummy 2 and a wandlessly on dummy 3.

I slowly walked out of the ring with a Incendio from my wand over the shoulder and turned back.

As expected, the damaged dummies disappeared, and new dummies stood up. This time they are moving a bit faster.

AI, what's the result of the test?

[The room has increased the speed of Dummy's spell activation by 2% and it's material is more fire resistant by 5%.

The Impedimenta mastery – 32/100

Incendio- 89/100]

This room has AI. This confirms it. The room has been preparing a gradual increased difficulty helping in my training.

The room seems to have been made of alchemical magical alloys and enchanted on top of it construct anything needed by the user. A temporary material like the Dummies and fake wands in it. Though the spells are enchanted on the Dummies up on their creation by the room. From the Access to Hogwarts wards it can get books' copy from the library, as they are integrated into Hogwarts ward scheme. It's no wonder, no one tries to steal them.

[Current reserves : 5 units]

I decided not to risk Magical exhaustion and went to the study table, bypassing the potions lab filled with ingredients.

That's right the room provided ingredients. I soon released they are under stasis spell. From the information provided in room I found that the spell literally puts the entire existence of the target from being effect from time. Though requires consuming different amounts of units based on the target. A piece of wood – 1 unit. A pizza-5 units. All these are consumed once a day from the caster of spell. But for living things, the consumption increases exponentially.

Saint mungo's is famous because it exists on a minor Leyline and dedicated it to making ward stones to anchor the stasis spell. So as long the person is alive when he reaches the saint mungo's then he is guaranteed to stay alive, at least here is hope for treatment.

But the exorbitant prices for stasis can only be paid by only a few.

My desire for more knowledge is interrupted by my desire for food. The room can't make food but can contact the one who makes it. Afterall both the room and them are symbiotic parts of Hogwarts. That's right, I am talking about House elves.

[Ting. Ting.

House elf: Symbiotic beings to witches and wizards or places of magic like Hogwarts , who seem to have talent in spades but can't produce their own magic.

Hypothesis no 42: House elves us the Host's magic to perform their magic. As told, they are symbiotic beings, they get magic from the host but their benefit to host is the one in question. The enslaved work is nothing but humans being humans.

The benefit I believe is living hosts like wizards they help in intent training by consuming their reserves to do magic. Afterall even if it's the house elves that's doing magic, it is still the Host's magic reserves. That's why they are commodities of purebloods. Overtime while majority lost the information by sands of time, or someone erased it.]

It is because someone erased it. Now the reason I am sure is because a book on House elves appeared in front me written by Helga Hufflepuff.

Normally, one would expect one to find books that entered all of Hogwarts to be found in the room. But it is far from the truth. It can only record the information which is not enchanted. Yes, enchanting against piracy is a thing.

I opened the book and started reading it with interest, after all this is the book written by one of the founders. Most importantly, the one of the greatest healers in history.

I turned the pages , again and again. I sighed at the Old English it is written in.

Here comes my cheat. AI translates. I am thankful for uploading the syntax of every language I could find.

[Translating…

Translation done.]

Well English understanding helped in faster processing of old English. I really should learn more.

[It was while travelling through Greece I meet a wounded wizard and House elf pair. It was curious that I found healing the wizard, helped the House elf by freeing up more of the wizard's magic for the House elf's use. I received even better response from the elf to my healing spell than the wizard. It got me curious enough to dig deeper into the issue…]

WTF, where is the rest.

[Translation completed.]

Huh. I saw a message forming on the book cover. Ok, AI, I choose you.

[Translation done]

[For one who realized the truth on House elves magic, I already given the requirements to be met to unlock the next pages]

Barmy witches. Does everyone powerful has a screw loose?

I immediately got up and vented my frustration on the Dummies, "Incendio."

Damn childish body, grow up fast. I want my control back.

After my tantrum, I made myself back to the seat. Re-read it again.

"Hmm, better response to her healing magic than the wizard even though possessing the same magic."

Got it, I need a House elf to bond. I know how to obtain one privately.

Room, send a message to a House elf ready to bond to come here. Also. Tell it bring some food.

POP

"Jakrey is here sir."

I soon saw a young house elf, one like dobby but with none of his wrinkles.

"Let's get to the point. Jakrey, do you want to be my House elf?"

Jakrey's eyes widened, and I can literally see his joy all over.

''Y Yes, Jakrey wants to."

I felt a bit of my reserves consumed by the bond similar to wand but not the same way. It is an odd feeling.

[A partial soul resonance is found between the house elf and Host.]

That explains the control of my magic.

[Elf's current reserves are being converted to hosts magic ; Host's reserves are full.]

[Bond was established by consuming 3 units. A part of host's magic is being is sent to the Elf.

Current reserves: 40 units

Elf reserves: 5 units]

Ok, that is a daily consumption of 5 units, not to mention the additional units upon usage. No wonder none the pureblood kids have House elves.

I summoned the book and gave it to excited Jakrey.

AI make sure to record.

"Open it."

He does and nothing changes.

"Try to inject magic into it."

"Inject magic, Yess sir."

No, change. Obviously, it won't that easy.

[recorded Jakrey's magic]

My eyebrows rose at that, AI show me the process of Jakrey's magic.

{ initializing.

I felt my magic move with each word uttered "INJECT MAGIC, Y Yes SIR."

Completed}

Fucking hell except the small stretched out part , every word he uttered is mobilizing magic.

I saw Jakrey looking up at me while tilting his head, I rubbed his head and said, "It seems you need to learn to not cast magic."
