The evening sun slowly sets towards the mountains of the Scottish Highlands, painting the clouds in the sky with layers of warmth.

On the edge of a majestic forest, on the shores of a deep lake, and on top of a steep cliff, a magnificent castle stands quietly.

The seemingly never-ending wind left the valley and swept the blue waves of the boundless forest, blowing the surface of the deep lake.

The wind howled under the stone bridge on the cliff by the lake, raising the black cloak and long blue scarf of the boy on the bridge.

Scott squinted in the wind, tugged at the collar of his cloak with one hand, and took a step forward.

Lady Gray floated beside him in a dignified manner, the wind passing through her transparent body, her hair and clothes moving in the wind.

"Let's go straight down."

Ms. Gray said to Scott.

"If you are here, you will be seen."

Scott stood inside the guardrail of the stone bridge, looking left and right.

"Everybody's still in class. And, what if you see it? ”

Miss Gray said unconcernedly, and slowly rose into the air.

"If you don't want to be seen, you should hurry, it's time to get out of class right away."

She floated over the guardrail of the stone bridge towards the bottom of the bridge.

"Okay."

Scott replied helplessly, looking up at the sky.

He put the thumb and forefinger of his left hand in his mouth and blew a loud whistle.

With the sound of "quack" from far and near, a black raven circled and flew in front of him.

"It's getting bigger."

Scott waved his wand in his right hand and pointed it at the raven, and the normal raven instantly became unusually large.

"I'm getting bigger! It's getting bigger! Scott! Rattle! ”

The raven flapped its wings excitedly and spat out human words.

"I've found some tricks to at least make you bigger."

Scott smiled wryly.

"Thank you, Professor Flitwick, for your teachings!"

He climbed the parapet of the stone bridge.

"Take me down, Rimbaud."

He said, then leaped to his feet and landed on the raven's broadened back.

"Gah!"

The raven let out an excited cry and took Scott into the air and flew towards the bottom of the bridge.

"Go to Ms. Gray."

Scott commanded.

At this moment, Lady Gray was floating on a boulder on the cliff face below the stone bridge, looking up at the huge ravens falling.

The raven soon landed on the boulder as well, and Scott climbed off its back.

"This isn't a real raven."

Ms. Gray looked at Scott with a complicated look in her eyes.

"It's your Transfiguration work."

"You read that right."

Scott nodded, waved his wand, and Rimbaud immediately changed to his original size.

It flew up and landed on Scott's shoulder.

"You've used a spell on Transfiguration!"

Ms. Gray said with some excitement.

"How is this possible, even if it's just a simple expansion spell, your Transfiguration Technique hasn't collapsed!"

"That's exactly what I'm looking at right now." Scott said, "I've learned a few things about combining spells with Professor Flitwick. ”

At the very least, you can use the Expansion Charm on Rimbaud, although it will only last for a dozen seconds at most.

Ms. Gray was still surprised, "Of course I know how difficult it can be!" Scott, you're more talented than I thought. ”

"Thank you for the compliment."

Scott smiled confidently.

"Now you should have more confidence in me."

Miss Gray nodded.

"Go ahead." She looked at the stone wall on the inside of the platform, "Open the entrance to that music room." ”

"Do you want to sing again......"

Scott frowned, reluctantly walked to the stone wall, and sang the school song of Hogwarts School of Witchcraft and Wizardry in a special tune.

The singing was quite beautiful, but Scott, who was halfway through the song, frowned.

Someone came to the stone bridge above him.

It's Fred.

That guy must have looked at the live spot map!

Scott thought helplessly, and continued to sing.

After singing the school song, a stone door appeared in the depression of the stone wall.

"Oh! Scott! ”

Scott heard Fred's exclamation.

He looked up at the red head poking out of the bridge.

"Hey!"

Fred held out his hand and waved.

"What are you up to? There's such a fun thing that doesn't tell us! ”

Scott shrugged his shoulders at Ms. Gray, "Looks like it was discovered before it even went in." ”

"Leave him alone, let's go inside." Ms. Gray said.

Skod's head.

He waved at Fred above and pushed open the stone door.

"Hey! Wait for us! Fred shouted, "George went get a broomstick!" ”

Scott didn't respond to him, waved his hand again, and walked straight inside the door.

The majestic organ music sounded, and the stone door shut.

In the darkness, the magic lamps on the walls on both sides of the corridor lit one after another.

Scott and Ms. Gray headed deeper into the hallway.

"Next...... If Fred and George hadn't kept it a secret, plus I skipped class in the afternoon......"

He said helplessly.

"The eyes of the whole school will be focused here."

Still unimpressed, Ms. Gray said, "I'll explain this to the professor for you, and you should focus on the upcoming challenge." ”

"Okay."

Scott felt that her words were correct, so he took a few deep breaths to calm down.

It wasn't long before he stepped into the empty hall again.

Beneath the towering stone walls of the organ, Medea, dressed in splendid costumes, sits in front of the bandstand with her back to them, her hands dancing on the multi-layered keyboard.

Scott stood quietly, neither he nor Mrs. Gray had any intention of disturbing Medea.

Scott even closed his eyes slowly.

Delightful musical magic......

Maybe you won't be able to experience it again.

Let him cherish what may be his last aid......

Soon, the distractions in his thoughts were slowly emptied in the sound of the music.

After a long time, when the music stopped, Scott slowly opened his eyes.

There was a gleam of joy in his eyes.

He gained a lot more this time than the previous two times.

Even the range of magical perception has expanded significantly.

It's just that...... I don't know why Medea suddenly became generous?

He had been worried just now that Medea had come to an abrupt end in the middle of the song.

It didn't feel good.

From the first two dealings, he didn't think Medea was a good talker.

However, although he couldn't figure it out, Scott was not prepared to delve into this issue.

In short, today he is just a tool man who has been commissioned by the Ravenclaw mother and daughter.

"Here you go again."

Medea took her hands off the keyboard and slowly got up.

She turned, her eyes looming in the dark veil to look at Ms. Gray.

"Helena."

She asked in an unwavering tone.

"What are you doing again?"

"Break the oath."

Ms. Gray floated forward for some distance.

"According to the contents of the oath, the oath is broken."
