"What kind of magic you ... are doing?" Helene's expression is brilliant.

" A kind of application of memory magic." Felix explained, a fine layer of sweat dipping out of his forehead, "Can you stay for a while? To be honest, I'm not very good at this magic yet."

She paused. .

Felix's head got a little dizzy, having constructed a huge amount of memories in just one moment and using them all at once, making his mind foggy.

Helena looked at him with concern.

Felix took a few deep breaths and felt much better. He said to Helena, "We're friends, aren't we?"

"Of course."

"Forgive me for taking the liberty, ma'am. From your story, instead of hating the other guys, I'd say - you're hating yourself."

Her expression fell silent for a moment, and she turned her body slightly sideways, keeping half of her face in the shadows.

Felix eased his tone as much as possible: "Why did you become a ghost, is it because you fear death? From my contact with you, I don't think so. What really bothers you is your inability to let go of the guilt you feel for your mother."

He said with an extremely serious expression, "Bloody Baron has been carrying the shackles for a thousand years, how could it be otherwise for you? I hope you will try to forgive yourself ..."

The night enveloped the castle and after a long silence -

"The one person who could forgive me has disappeared forever, on the third day, when I became a ghost," Helena said icily, turned and floated away.

This time, Felix didn't bother to stop.

...

Ghosts are born from obsessions, and the thoughts before death are the most radiant and intense. So most ghosts' obsessions are born out of a fear of death and an escape mentality.

Those like Helena, Baron, and Professor Binns are few and far between.

For Helena, her obsession is one of guilt and regret - regret that her ignorance led to a big mistake, regret that she did not believe Baron's words, and guilt that she did not see her mother one last time and apologize to her in person ...

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

Through his conversation with Helena Ravenclaw, he suddenly came up with an angle he had never considered before.

He thought to himself, "I want to find the room that Rowena Ravenclaw left for her daughter, Helene Ravenclaw ... I want to find the room that Rowena Ravenclaw left for her daughter, Helene Ravenclaw ... I want to find the room that Rowena -Ravenclaw's room left to his daughter, Helena Laenklau ..."

Will it work? It's reasonable to assume that there shouldn't be such a loophole ...

Felix slowly opened his eyes, a plain blue door, drawn from white walls, appeared in reality.

On the door, a silver-white handle emerged.

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

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

Inside the door is a very simple room, the room is not large, with a few simple tables, chairs, flowers, books, the place is spotless, giving people a sense of tranquillity and warmth.

"Is anyone here?" He asked.

After a long time, he did not get any response. He tapped his forehead with his finger and switched his own perspective.

The colour faded fast, and a ripple spread out, centring on him.

Felix saw the magic that seemed like substance and coiled in the deepest part like silk spread out, a dozen magic channels like chains that went deep inside through the air.

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

...

For the next few days, Felix kept wavering, having trouble making up his mind.

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

And what lay deep within the magic, much like silk, he had a suspicion that it might be a memory left behind by Lady Rowena Ravenclaw.

He didn't know why he was allowed in, maybe he mentioned the name Helena Ravenclaw? And the memories left behind by Lady Ravenclaw were still dormant before he made the discovery.

According to common sense, he should have told Helena Ravenclaw about it right away, it would be good for both parties - Helena might reconcile with her mother, and he could use the opportunity to ask about some mysteries of magic, or if he is lucky, he could even get the Ravenclaw legacy.

But he found himself not looking forward to this event much.

For the ghost, moving 'on' would mean relief, but what would it signify for the people who had, in reality, developed a friendship with the ghost?

Felix felt confused, his experiences did not help him, so he chose to ask someone with more wisdom.

"Headmaster Dumbledore, how do you feel about 'death'?"

"Well ... Felix, why do you suddenly ask this question?" Dumbledore looked at him with some confusion.

"Because of some matter of feeling."

Realizing that Felix did not want to explain, Dumbledore thoughtfully did not ask more questions, he pondered, smacked his lips, and said, "Everyone has a different view of death, fear, avoidance, disgust ... but for some people, such as me, have a welcome attitude."

"Welcoming?" Felix wondered if he had misheard.

"Felix, for an old man like me, nothing in the world would make him flinch; death to me is just an unknown, new, and interesting thing, like an entrance slip to a great adventure."

Felix shook his head, this is different from his concept, he may not fear death, but he will not look forward to it either.

He asked what he was most concerned about, "So what do you think the existence of ghosts means?"

"Ghosts? They are stranded in reality due to strong obsessions ..."

"No no, Headmaster Dumbledore," he interrupted Dumbledore, "please forgive me, perhaps I did not describe it very well ..."

Dumbledore looked at him understandingly, giving Felix time to reorganize his words, and this time Felix asked, with caution, "Ghosts exist because of their obsessions, and they are liberated when their obsessions disappear. Is that correct?"

"That's right." Dumbledore blinked and said approvingly.

"And what does this liberation count as? Another death? Especially for her living friend, in reality, I mean ... that's forever separation, no different from death."

"She?" Dumbledore asked.

Felix remained silent and did not answer.

Dumbledore thought carefully for a moment before saying, "Different people may have different interpretations, I can only say what I think about it for your reference."

"This is exactly what I came for, to rely on your wisdom to help me see a few things clearly," Felix said.

"For ghosts, there is no doubt that 'keep moving on' is a relief. Being stuck in reality does not make them happy; in fact, while they can continue to speak and walk, they are unable to enjoy anything and are always bound by their obsessions - few choose to carry on their existence in this most deprived way."

"What about the living ones? What about the friends of the ghosts?"

"Only a blessing." Dumbledore said calmly: "It may be that I have experienced so much that I always see things soberly, somehow ..." he said softly, "and even somewhat inhumanly."
