This is what Ravenclaw looks like.

"This is completely inappropriate..."

Returning to his own dormitory, Andrew spread himself out on the bed, feeling a headache.

His range of spellcasting was smooth, not to mention proficient, but it did not meet the professor's needs at all. He originally thought that he would be able to comprehend the vital changes of spring, summer, autumn and winter during the spellcasting, or something mysterious and mysterious, but today's spellcasting directly gave him He was confused.

Just kidding, how could this be right - using seeds to assimilate tree roots, then grow latently, and eventually grow quickly in the next year.

Andrew didn't believe that this thing had nothing to do with the professor's request, but it had nothing to do with what he had thought about before!

'I really can't understand...'

He waved his wand, skillfully turning the tree root he placed beside the bed into a ball of flame, and then held it in his hand.

The flame that was supposed to be burning suddenly lost its astonishing temperature and the ability to control its shape. He pulled it on his hand like playing with plasticine, bringing with it a bit of warmth, which was quite useful in winter.

'What exactly are you asking for...'

Andrew stretched the flame, and the uncertain flame gradually formed the shape of a scarf, and then he fixed it with a wand, and then floated in the air.

"The stability and strength of ordinary transformation spells have improved a lot...even the range of transformation spells has been extended to things that have no entity and don't even know whether they should be considered items..."

He stared at the flame scarf in the air, confused, "But what's the use? This thing can't even be worn out, because it will quickly lose its temperature and turn into a smoke-like existence. As for burning items, I even It can only be in a fixed state and cannot be transformed..."

After waving the wand to eliminate the scarf, Andrew put his hands behind his head and sighed, "It's difficult. This kind of thing doesn't even have any hints?"

"No, the professor is giving hints, but they are careful every time - could it be that the more hints, the harder it is to understand?

"Hell, it's not the Department of Mysteries. Why do we have so many Riddlers?" Andrew got up and said, "I won't think about it anymore. Today I will review what I learned earlier and see if I can learn something new and get some inspiration..."

"Is this the depths of the Forbidden Forest?"

Harry's face was full of disbelief - this was his first time entering here, and if Sirius hadn't brought him along, he didn't know when he would be able to come.

"Of course, this is it," Hagrid let out a hearty laugh, "Where else could it be? Be careful of those tree roots, Harry, this is far from the campus hospital."

Not only tree roots, but also tree vines and unknown tough grass - Harry bet that it was definitely something from a part of herbology that he had not touched.

"It's such a nostalgic place, Hagrid. We were captured by you many times from here."

Sirius said nostalgically - in those days, the Forbidden Forest was simply their home field.

"But you don't do that anymore in senior year, do you?"

Hagrid smiled while lowering his head to cheer Fang up - the poor ordinary hound, which was not even level x, broke into a place with an average challenge level of

'There was the Marauder's Map then, and you couldn't catch Hagrid...'

But Sirius didn't intend to say anything about it, "After all, I'm a little older, but I really miss it..."

"It's been a long, long time," Hagrid sighed, but quickly cheered up, "But it's good to go shopping now. Come on, let's go to the unicorn territory."

He was really happy - he even dug out Sirius' flying motorcycle and started renovating it, and it was even less stressful to take the two of them to visit the Forbidden Forest.

"Mr. Taylor."

With a banging sound, Andrew, who was happily transforming into an animal model, was awakened. A house elf he was unfamiliar with appeared.

"ah?"

"The wood has been stored, please go and check it for acceptance."

Is there still this link?

But after all, it was an extension of the office tasks. Andrew got up from the bed, put on his clothes, and followed the elf's guidance to the so-called firewood room.

To be honest - he had never seen a place like this, a place where the entire school's winter firewood could be piled up - it was definitely not a small room.

Soon, he was taken underground and came to an ordinary empty classroom.

The elves knocked on the wall close to the ground, and then the entire wall was lifted open, revealing a door about one person wide.

"This way, Mr. Taylor."

He followed the elf and walked in casually, and then his eyes widened.

Piles of firewood were piled up like small mountains, and on average they were as tall as two people - but what surprised Andrew was not this, but the size of the room, which was so empty that it seemed as if the castle had been hollowed out...

‘How many times is this invisible expansion? ’

He couldn't calculate it, but he could feel the power of the powerful spell - the room was so big that it couldn't even light up, giving him the shock of being in a civil air defense project by mistake as a child.

"How long has this been here?"

Andrew couldn't help but ask.

"It has been used since the school was founded."

"It's amazing, it's amazing, such an existence..." Andrew shook his head. He doubted that he would be able to use such a spell in his life.

This oppressive feeling, this spell that feels insurmountable - wait!

Andrew suddenly wakes up...

No, why can he feel such a spell?

This was the first time that he felt the power of a spell so clearly, as if someone had used this spell to reverse... No, not reverse, but change!

Yes, it’s not a twist, it’s not a seamless expansion, it’s a change, it’s a deformation!

Yes, a permanent transformation spell was cast on this place, and what that spell changed was - yes, that, that!

His eyes widened, not wanting to miss a single detail. Yes, that's right, no problem, the professor was not talking about that, but this!

It's this, yes, because of practicing and pondering over and over again, he can feel this.

rule…

Yes, the rules…

This powerful transformation technique changed the spatial rules and range rules of this place.

That's it, that's the answer.

Just like the rules set on the chessboard, the rules here are communicated and changed...

If it weren't for this transformation technique, he would probably have to think about it for a long, long time...

Rules - Yeah, McGonagall is good at that.

Last year, she created a deformed chessboard formation that was circulated throughout the school, and there, the rule was that the chess pieces must be replaced to win.

Not only that, even Voldemort can create a lake that can only be passed by his own limited tools... That is a strong application of rules.
