Hogwarts: The Cat Wizard of the Moving Castle

"I have indeed heard of this." Moon nodded: "But because of Professor Binns's physical condition, I have not studied it in depth."

"In fact, there is no need for any research." Ms. Gray shook her head: "But you really don't have such a long life to observe the existence of ghosts."

As she said, she slowly sat down on the sofa, her posture was calm and her tone was gentle.

"Ghosts are indeed a kind of magical creatures. Muggles without magic power can never become ghosts.

In addition, the formation of ghosts must be due to physical death. There are many ghosts in Hogwarts, but no one has ever died because of the Killing Curse."

Moon agreed with this statement and thought: "The essence of the Killing Curse is to banish the soul from the world. This is why Riddle can still keep his soul intact and return to the world to resurrect after being rebounded by the Killing Curse."

"That's right." Ms. Gray nodded.

"There is another kind that cannot become a ghost."

As she said, a trace of disgust flashed in the depths of her eyes.

"That means people who commit suicide cannot become ghosts. Except..."

"Except Sir Barrow?"

"Yes." Ms. Grey couldn't help but hold her forehead, expressing her deep distress because of Barrow's existence.

"The existence of ghosts must be due to the unacceptable death and strong desire for death.

My mother said that both [ghosts] and [obscure] are products of magic under extreme emotions.

So ghosts are essentially a person who is physically dead, but his will and mind are unwilling to die, so they will be intertwined and merged with magic, and then such a [ghost body] will appear.

This is also why ghosts cannot cast magic, but can rely on their own magic bodies to perform tricks such as passing through walls, passing through the body, and absorbing the vitality of food.

As for Barrow, he is a suicidal person, but he can form a ghost.

In general, ghosts are a peculiar product of human beings from life to death. In the process of our life to death, because of the meshing of magic and extreme emotions, we stay in the real world with another body.

But this is not absolute. After all, in history, there are too many wizards who have been persecuted, but not every wizard can become a ghost."

As she said, she sighed helplessly.

"I think you understand the reason."

Moon nodded and didn't take up the topic.

Barrow was indeed a bit extreme.

After thinking about it, Moon still felt that he should bring the topic back.

"So you just said you were going to leave?"

"Yes." Ms. Grey nodded: "My obsession with this world is gone. The crown has been found, and the knot with my mother has dissipated."

As she said, she stood up and looked at Harry.

"And this crown has also been handed over to a trustworthy young wizard. If there is anything to be regretted, it is that it is a pity that Sir Potter is not a student of Ravenclaw."

"Ms. Grey, thank you for your trust." Harry hurriedly bowed in fear and trepidation to thank him.

"Call me Helena." She smiled gently.

"I have nothing worth reminiscing about. In fact, if a person really gets a life that is too long and does not have the insensitivity to the passage of time like a goblin, it is undoubtedly a tormenting thing.

Especially. Forever ordinary, never able to interfere with this world."

"Regarding ghosts, your theories and insights, I think they are enough to be considered a very important discovery for the magic world." Mu En said: "I will sort them out soon, if you are willing."

Hearing this, Helena looked at Mu En in disbelief.

"What did you say, Professor Jones?"

Facing the trembling pupils, Mu En repeated his words again.

She took a deep breath, shifted her sight, and looked around aimlessly in the entire laboratory in a panic.

The only thing visible was her chest that kept rising and falling because of the shaking of her heart.

After a while, she turned her back to the two of them.

"Thank you. Thank you very much."

As she said, she turned her head.

"I have always been in the shadow of my mother. I have always wanted to surpass her wisdom and achievements, so I did those stupid things later.

I am sorry for your loss of composure. What the professor said just now means a lot to me. Thank you."

As she said that, she turned around, lifted her skirt with both hands, took a small step back with her left foot, and bowed deeply to Mu En.

"No need to do that." Mu En said: "The achievements and insights of every scholar should not be buried. I am lucky to be able to talk to you and gain these profound and secret knowledge."

"Thank you." Helena thanked again.

"It's a small matter." Mu En nodded.

"Then I won't bother you, professor. I roughly estimate that my body will gradually disintegrate in two or three days. During this time, you can come to communicate with me if you have any questions." Helena said.

Obviously, she attaches great importance to her [knowledge] that is about to be recorded.

"Okay." Mu En nodded, and then Helena said goodbye to the two of them and turned to leave the laboratory.

After confirming that Helena had disappeared, Harry could not wait to come to Muen.

"Uncle Muen, is everything you said true?"

"It's not true." Muen shook his head.

"Those rubbish [insights] that have no depth and can only come out of their mouths are not worth recording. They are just polite words."

Harry nodded, then hesitated for a moment and said, "That's not what I want to ask."

"What is that?" Muen looked at him.

"Well, it's the knowledge that Miss Helena said. Is it true?"

"From my experience, it is highly credible, but these may still need to be observed and verified. After confirming these, I will indeed compile them into a volume and leave the name of Helena Ravenclaw."

Harry nodded, then felt a little confused.

"Is this kind of thing. A very important thing?"

"It is for many people, especially researchers. For Helena, perhaps because of the influence of her family environment since childhood, this matter means more to her."

"So that's it."

"Right." Muen turned his head.

"There will be an event about Merlin's Order in May this year. Scrimgeour told me that he has submitted your name, Hermione's and Miss Lovegood's name. And Neville, he deserves an honor for his work on child trafficking last year."

"Neville really deserves it." Harry smiled, and he didn't have too many psychological fluctuations about his so-called honor.

"Of course, you just need to know about this matter. After all, Draco Malfoy is a man who can't keep secrets."

"Okay."

Late at night, in Hogwarts.

Harry returned to the lounge tiredly, went into the dormitory, and then took out the box from under the bed and went into it.

Because of the Ravenclaw laboratory, his box and the laboratory can only be separated now, so he had to move the box back to the dormitory again.

The potion is being brewed, the color is deep red, and it is bubbling with extremely thick liquid.

It is in line with the potion formula given to him by Professor Snape.

Harry once thought of using the same ideas and methods as the Half-Blood Prince to modify the formula given by Professor Snape.

But it is completely impossible to do it.

Professor Snape's attainments in potions were so high that Harry could hardly compare to him now.

Then, he finished the homework assigned by other courses, and only slowly climbed out of the box until it was almost two o'clock.

He fell on the bed tiredly.

Pah-Pah-Pah--

When he opened his eyes again, he saw Draco's face that deserved to be slapped.

"It's rare that I actually have a day to wake you up." Draco raised the corner of his mouth and showed a disdainful smile: "Tell me, what did you do with Granger yesterday?"

"???"

"Did Professor Snape take your brain to make pig brain potion? Otherwise, how could you say such a thing."

As he said, he reluctantly moved his body and went to the bathroom.

"Okay, then tell me why you fell asleep here? Instead of on the eighth floor."

"Some other research." Harry yawned loudly.

After washing up, Harry and his friends went upstairs.

When he arrived at the hall, he was not sleepy at all.

Helena was looking at Sindel.

And Muen was holding a steaming coffee cup, and he didn't seem to be sleepy at all.

"Then Helena, do you think her current situation is similar to that of a ghost? From the composition of the soul."

The other little wizards also looked at Helena.

That was Neville, Hermione, Ron and others.

Although they didn't understand much, it didn't stop them from listening here.

At least the feeling of knowledge passing through the head and not being able to stay at all was quite fascinating to them.

A little witch like Hermione was thinking that even if she didn't understand, she had to write it down first.

Helena thought for a moment, and then said the answer.

"Maybe. This is a process from death to life. However, if you want to get rid of the shackles of the portrait..."

After a moment, she shook her head.

"Maybe there is only magic."

"Magic." Muen murmured, and began to check in his mind. This answer was not the answer he wanted.

After all, magic comes in many forms, such as earth, water, wind, fire, etc., or in the form of potions, alchemy, and curses.

"The magic of the heart." Helena said.

"Leave it to the heart, leave it to emotions and thoughts, in the words of some wizards, it is love. Love is the greatest magic."

"Well, I think I still need some thinking." Mu En nodded slightly: "After all, I may not be very good at meshing emotions and magic together. Especially when it comes to such advanced theories, I will be more inclined to..."

"Logical, conceptual knowledge, or the so-called truth?" Helena said.

"That's right." Mu En smiled frankly.

"My mother was once the same as you." Helena smiled and said no more.
