Once upon a time, there was a powerful spell circulating in Hogwarts.

It is said that this spell has an unparalleled effect, as long as you encounter a difficult situation that you cannot solve, this spell can carry you out of trouble.

Many years ago, student A, who did not want to be named, said: One night, I was tied up by a few vines in the Forbidden Forest, and if I hadn't used that spell at the last moment, I would have become fertilizer in the field.

Student B said: My broomstick was hidden by Peeves that day, and I searched all over the castle but couldn't find it. In desperation, I used the spell, and my broom returned.

……

There are many similar legends on campus, but the last time this spell was used was ten years ago.

It was the day of the final battle, when Hogsmeade's defeated soldiers and refugees gathered to take refuge in Hogwarts. At that time, an atmosphere of defeat enveloped the entire castle.

At this moment, a wizard who had just graduated from Hogwarts collapsed under pressure and raised his wand to cast the most powerful spell Hogwarts had ever seen.

"Dumbledore Flies In"

The next moment, Aberforth Dumbledore, who was not far away, flew up.

After listening to the story, Arthas and Gianna were told that they could use the "Headmaster's Flying Charm" if they were in danger in the castle. If things are not urgent, then go a little more and go to the principal's office to find the principal. If the principal is not there, they will find the vice president, and for the sake of Zhang's face, Professor Flitwick will help them. If neither the president nor vice-chancellor is there, then go to Professor Rodney, followed by Professor Lupin or Professor Longbottom, and if not, go to my uncle. As for the current president of the Snake Academy, Zhang and Ma agreed that this product was not very reliable.

Now that her brother is missing and an unknown object in the castle seems to tempt her, Gianna, sensing that something is wrong, runs to the door of the principal's office.

≡(｀)(`)

Gianna ran to the door of the principal's office and saw two stone beasts standing guard in front of the office gate.

"Can you let me in and find the principal, please?" Gianna knew that the two stone beasts had a certain amount of intelligence.

"The principal is not in the office." The stone beast on the left said.

"My brother is missing in the castle!" Gianna said anxiously.

"It's an emergency!" The stone beast on the right shouted, and then got out of the way to the gate.

"You go in first and wait." The stone beast on the left also jumped to the side.

In ten years, little has changed in the Headmaster's Office, and the only thing that is different from before is that the Sorting Hat is gone.

Ever since getting a body two years ago, the Sorting Hat has asked Professor McGonagall for a room near the Principal's office to be his living room, so that she can lubricate her joints.

But tonight the Sorting Hat happened to be here to chat with the portraits of the headmasters.

"What's the matter, little girl?" The Sorting Hat knew Gianna, having met the Black siblings when she left Hogwarts to collect her new body and post-testing.

"My brother is missing." Gianna said to the Sorting Hat.

"Oh!" The Sorting Hat covered its mouth with its silicone-skinned hands.

By the way, the Sorting Hat has no head on its body, and there is a ball on its neck for the hat, which usually hides the ball that represents the highest level of magic at the beginning of the 21st century when the hat hangs down. It can also be said that the Sorting Hat in this state has a tall, pointed, triangular head.

However, the Sorting Hat quickly patted Gianna on the shoulder and said, "Don't worry, maybe something good will happen to him." ”

At this moment, Professor McGonagall, who was full of after-bath breath, appeared in the principal's office.

Gianna reports to Professor McGonagall what happened tonight when Arthas went to the library to borrow books and what was wrong in the room at the end of the hallway on the fourth floor.

Professor McGonagall took out the Spot's Map, placed it on the table, and began to look for traces of Arthas.

Unlike the original Living Point Map, the Principal's Edition has a lot of expanded features after years of development.

Professor McGonagall tapped her wand on the map and said, "Show Alsace Black's location." ”

As a result, there is a blank space on the map of the active spots, and only one line is displayed on it: According to relevant laws, regulations and policies, the results of your search are not displayed.

Professor McGonagall's face darkened when she saw this for the first time.

She then proceeded with her wand on the map of the living spot and said, "Show the trajectory of Alsace Black tonight." ”

Now there was movement on the map of the living point, and the canteen on the first floor appeared on the map, and the name of Alsace was bold and bright in one of the names.

Then Arthas's name left the cafeteria and walked to the library, where he lingered for a while, and his name suddenly disappeared as he walked to the library door.

Seeing this, Professor McGonagall's frown loosened slightly, and Gianna was so frightened that she was about to contact her eldest cousin immediately.

"He should be fine." Professor McGonagall was aware of the existence of the copy of the lower hundreds, "I guess you can go to the E-13 room on the fifth floor and wait for him." ”

"Really?" Gianna looked at Professor McGonagall suspiciously, it was a little strange for her.

"Yes." Professor McGonagall nodded, and Gianna immediately ran out of the office.

"I'll check it out too." The Sorting Hat departed, but it couldn't run yet, so it walked away at a brisk pace.

"Looks like there's another lucky guy!"

"I don't know how long he can last in there!"

"The person surnamed Black will definitely make it to the end!"

There were some things that the students didn't know, but the headmaster's portraits knew very well, so they chatted right there.

Gianna soon found herself in room E-13, where Dumbledore used to answer questions about students' homework on Friday nights. However, when Professor McGonagall became Rector, she moved to her former office on the second floor.

Gianna slammed open the door to the classroom, it was pitch black and the air was filled with the smell of dust, so she drew her wand and lit up the classroom.

_(3∠)_Σ(д)

As soon as she entered, Gianna saw her brother lying lifeless on the ground, surrounded by a large patch of bright red blood.

(д): "No! ”

Gianna was so frightened by the sight that she covered her eyes, she didn't dare to look at Arthas's cold body on the ground.

＿|￣|○/｀w\__θ_(3∠)_

At this point, the Sorting Hat appeared, and it passed over Gianna, who had collapsed to the ground in fright, and then kicked the guy on the ground.

After a punch and kick from the Sorting Hat, the corpse on the ground, along with the blood, suddenly turned into a cloud of black smoke with a "bang", and then rushed out of the classroom.

It was then that the Sorting Hat lifted the bloodless Gianna to sit aside, and said to Gianna, "Don't be sad, it's just that the Boggart that Lupin used for class has escaped again, and it is likely that Peeves has released it again." ”

Gianna only recovered at this time, wiping the tears from her face and giving a soft "um".

"What about my brother?"

As soon as Gianna's words fell, there was a "bang" in the middle of the classroom, and a heavy object fell from the air.

"It's finally out!" Lying on the ground, Arthas breathed a deep sigh of relief, "Ouch! ”

This time it was Gianna's turn to go up and kick her a few times.

"What are you doing here?" Arthas, who had no strength, shrunk himself into a ball, and he found that his sister was angry, "Hurry up and help me up, I have something good for you to see!" ”

Gianna helped the exhausted Arthas to a dusty chair and sat down, then took what her brother had handed her.

"Isn't it just a pair of glasses?" Gianna said disgustedly, "It's a good thing, you're not short-sighted." ”

"How could the glasses I had worked so hard to get such a simple thing!" Arthas protested, "Looks like I'm destined to be the protagonist, hahahaha...... Yes! ”

Gianna withdrew the hand that pinched her brother, and said: "You have seen too much on the Internet, don't tell me what adventures you encountered when you disappeared, and then pick up things like when you are a treasure old man, such an article is about to be written rotten." ”

Then Arthas stopped talking.
