"You...what kind of magic is this?" Helena's expression was wonderful.

"It's an application of memory magic." Felix explained, a thin layer of sweat on his forehead, "Can I stay for a while? To be honest, I'm not very good at this magic yet."

She paused.

Felix's head was a little dizzy. He had just constructed a large amount of memory in an instant, and then used it all up at once, making his head dizzy.

Helena looked at him with concern.

Felix took a few deep breaths and felt much better. He said to Helena: "We are friends, right?"

"Of course."

"Forgive my presumption, ma'am. From your story, it's better to say that you hate yourself rather than others."

Her expression suddenly became silent, and she turned her body slightly, hiding half of her face in the shadow.

Felix tried to slow down his tone as much as possible: "Why did you become a ghost? Are you afraid of death? From my contact with you, I don't think so. What really bothers you is that you can't let go of your guilt towards your mother."

He said with a very serious expression: "The Bloody Baron has been shackled for a thousand years, and so have you? I hope you can try to forgive yourself..."

The night enveloped the castle. After a long silence,

"The person who can forgive me has disappeared forever, on the third day after I became a ghost." Helena said coldly, turned around and floated away.

This time, Felix did not stop her.

...

The birth of ghosts comes from obsession, and the thoughts before death are the most brilliant and intense. Therefore, most ghosts' obsessions are out of fear of death and escape psychology.

There are very few cases like Helena, Barrow and Professor Binns.

For Helena, her obsession was guilt and regret. She regretted that her ignorance had led to a big mistake, regretted that she did not believe Barrow's words, and felt guilty that she did not see her mother for the last time and did not apologize to her in person...

That night, he appeared in front of the white wall of the Room of Requirement.

Through the conversation with Helena Ravenclaw, he suddenly thought of an angle he had never considered.

He muttered in his heart, "I want to find the room that Rowena Ravenclaw left for her daughter Helena Ravenclaw... I want to find the room that Rowena Ravenclaw left for her daughter Helena Ravenclaw... I want to find the room that Rowena Ravenclaw left for her daughter Helena Ravenclaw..."

Felix slowly opened his eyes, and an ordinary blue door appeared in reality with lines drawn on the white wall.

On the door, a silver-white handle protruded.

Felix's hand was on the door handle, but at this moment, he suddenly hesitated.

After a long while, he pushed the door open firmly.

Inside the door was a very simple room. It was not big, with a few simple tables and chairs, flowers, and books. It was spotless and gave people a sense of tranquility and warmth.

"Is anyone there?" he asked.

After a long time, he did not get any response. He tapped his forehead with his fingers and changed his perspective.

The colors faded quickly, and ripples spread out with him as the center.

Felix saw the magic that seemed to be real and the silk-like stretching things entrenched in the deepest part. A dozen magic channels penetrated into the air like chains.

'This is the real core of the Room of Requirement.'

...

In the next few days, Felix was wavering and could not make up his mind.

He had realized that the core of the Room of Requirement was that room.

And he also had a guess that the silk-like thing deep in the magic might be the memory left by Ms. Rowena Ravenclaw.

He didn't know why he could go in. Maybe it was because he mentioned the name Helena Ravenclaw? The memory left by Ms. Ravenclaw was still dormant, which made him discover it.

According to common sense, he should tell Helena Ravenclaw about this immediately. This would benefit both parties. Helena might reconcile with her mother, and he could take the opportunity to ask about some magical secrets. If he was lucky, he could even obtain the inheritance of Ravenclaw.

But he found that he didn't have much expectation for this matter.

For the ghost, continuing to "go on" means liberation, but for those who have established friendship with the ghost in reality, what does this mean?

Felix felt confused. Past experience could not help him. He chose to ask a wiser person.

"Principal Dumbledore, what do you think of "death"? "

"Um... Felix, why do you suddenly ask this question?" Dumbledore looked at him puzzled.

"Because of something that made me feel emotional."

Realizing that Felix didn't want to explain, Dumbledore didn't ask more questions considerately. He thought about it, smacked his lips and said, "Everyone has different views on death, fear, avoidance, disgust... But for some people, like me, they welcome it."

"Welcome?" Felix wondered if he had heard it wrong.

"Felix, for an old man, nothing in the world can make him feel afraid. Death is just an unknown, fresh and interesting thing to him, like a ticket to a great adventure."

Felix shook his head. This was different from his concept. He might not be afraid of death, but he would not look forward to its arrival.

He asked the question that he cared about most: "Then what do you think the existence of ghosts means?"

"Ghosts? They are stuck in reality because of strong obsession..."

"No, no, Dumbledore," he interrupted Dumbledore, "Please forgive me, maybe I didn't describe it clearly..."

Dumbledore looked at him with understanding, giving Felix time to reorganize his words. This time he asked carefully: "Ghosts exist because of obsession, and they will be freed when the obsession disappears. Right?"

"That's right." Dumbledore blinked and said in agreement.

"Then what is this kind of relief? Another death? Especially for her living friends in reality, I mean... that is a permanent separation, which is no different from death."

"Her?" Dumbledore asked.

Felix was silent and did not answer.

Dumbledore thought carefully for a while before saying, "Different people may have different understandings. I can only tell you my thoughts for your reference."

"This is exactly why I came here. I want to use your wisdom to help me see some things clearly." Felix said.

"For ghosts, 'keep going' is undoubtedly a relief. Staying in reality does not make them happy. In fact, although they can continue to talk and move around, they cannot enjoy anything and are always bound by obsession. Few people choose to continue their existence in this most impoverished way."

"What about the living? What about the ghost's friends?"

"Only blessings." Dumbledore said calmly, "Maybe I have experienced too much, so I always look at things soberly. To some extent..." He said softly, "It's even a little inhumane."
