Chapter 218 Answer
“This doesn’t make sense at all…”

Returning to the dormitory where he was alone, Andrew stretched out on the bed and felt a headache.

His range spellcasting was smooth, if not perfect, but it did not meet the professor's requirements at all. He originally thought that he would have to comprehend some mysterious changes in the vitality of spring, summer, autumn and winter while casting spells, but today's spellcasting had completely confused him.

Are you kidding? How can this possibly make sense - using seeds to assimilate tree roots, then growing latently, and eventually growing rapidly in the next year.

Andrew didn't believe that this thing had nothing to do with the professor's requirements, but it was completely irrelevant to what he had thought before!
"I really can't figure it out..."

He waved his wand and skillfully made the tree roots placed at the head of the bed turn into a ball of fire, which he then took in his hand.

The flame that was supposed to be burning fiercely suddenly lost its amazing temperature and the property of being unable to control its shape. He pulled it in his hands like playing with plasticine, which brought a bit of warmth and was quite useful in winter.

"What exactly are you asking for..."

Andrew stretched the flame, and the flickering flame gradually formed the shape of a scarf, which was then fixed by his magic wand and floated in the air.

"The stability and strength of ordinary Transfiguration have been greatly improved... Even the scope of Transfiguration has been expanded to include things that have no entity and we don't even know whether they should be considered items..."

He stared at the flaming scarf in the air, confused. "But what's the use? I can't even wear this thing outside, because it will quickly lose temperature and turn into a cloud of smoke. As for the burning objects, I can only keep them in a fixed state and can't transform them..."

Andrew waved his wand to eliminate the scarf, put his hands behind his head and sighed, "It's difficult. Isn't there even any hint for this kind of thing?"

"No, the professors are giving hints, but they are very cautious every time - could it be that the more hints we get, the harder it is to understand?
"Damn it, this isn't the Department of Mysteries, why are there so many Riddlers?" Andrew stood up. "Forget it. I'll review what I learned before today and see if I can come up with some inspiration..."

"Is this the depths of the forbidden forest?"

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

"Of course, this is it," Hagrid laughed heartily. "Where else could it be if not here? Watch out for those tree roots, Harry. This is a long way from the hospital wing."

Not only were there tree roots, but there were also vines and some unknown, extremely tough grass - Harry bet it was something from the part of Herbology that he had never come across.

"It's a really nostalgic place, Hagrid. You caught us from here many times before."

Sirius spoke with some nostalgia - in those days the Forbidden Forest was simply their home ground.

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

Hagrid smiled and lowered his head to cheer up Fang - the poor ordinary hound that was not even level x had broken into a place with an average challenge level of xxxx, and was almost done for.

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

But Sirius didn't plan to say this, "After all, I'm a little older now, but I really miss it..."

"It's been a long, long time," Hagrid sighed, but quickly cheered up, "But it's nice to take a walk now. Let's go and take a look at the unicorn territory."

He was really happy - he even dug out Sirius's flying motorcycle and started to refurbish it, and there was no pressure at all to take the two of them to visit the Forbidden Forest.

"Mr. Taylor."

With a bang, Andrew, who was happily transforming into an animal model, was awakened. A house-elf he was not familiar with appeared.

"what?"

"The wood has been stored. Please go and inspect it."

Is there still this link?
But after all, it was an extension of the office task. Andrew got up from the bed, put on his clothes, and followed the guidance of the elf to the so-called firewood room. To be honest, he had never seen such a place, a place that could be filled with firewood for the entire school in winter. It was definitely not a small room.

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

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

"This way, Mr. Taylor."

He casually stepped in behind the elf, and his eyes widened.

There were piles of firewood piled up like small mountains, and on average they were two people tall - but what surprised Andrew was not this, but the emptiness of the room, which seemed to be hollowed out of a castle...

'How many times is this a traceless expansion?'

He couldn't calculate it, but he could feel the power of the powerful spell - the room was so big that he couldn't even turn on the lights, giving him the same shock as when he accidentally entered a civil defense project in his childhood.

"How long has this place been here?"

Andrew couldn't help but ask.

“It has been used since the school was founded.”

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

This oppressive feeling, this spell that feels insurmountable—wait!
Andrew suddenly realized...

That’s not right. Why can he feel such a spell?

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

Yes, it’s not twisting, it’s not seamless expansion, it’s changing, it’s deforming!

That's right, a permanent transformation spell was cast on this place, and the spell changed - yes, that's it, that's it!

He opened his eyes wide, unwilling to miss any detail. Yes, that's right, no problem, the professor was not talking about that, but this!

This is it, that's right. Only after repeated practice and thinking can he feel this.

rule…

Yes, the rules...

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

That's it, that's the answer.

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

If it weren't for this Transfiguration, he would have to think for a long time...

Rules - yeah, Professor McGonagall was good at that.

Last year, she created a modified chessboard formation that was circulated throughout the school. In that formation, the rule was that one had to replace the chess pieces in order to win.

Not only that, even Voldemort can create a lake that can only be passed through with the tools he specifies...that is an even stronger application of the rules.
