"Birdhouse, string, thread," Felix repeated.

He realized suddenly one of Ravenclaw's traits, she is very, very fond of inspiring people - whether the person wants to be inspired by her or not.

"Mother, can't you be blunter?" Helena said from the sidelines.

Ms. Ravenclaw gave her a look and helplessly revealed the riddle: "Don't crudely cram

Memories into anything, you need to shape them."

Felix seemed to have thought of something, but still separated by a layer of thin paper, shading in and out of view.

"Memory moulding, or rather, structuring a solid memory."

Ravenclaw held the rain swallow, which turned into a silvery mist and then reassembled into an eagle with its head held high, in the body of the eagle, there are dense dots all over..

The eagle landed on the ground and looked at the ground.

"These are?" Felix's breathing seemed to stop, he directly switched on the acceleration of thought, desperately remembering the structure of these dots.

Ravenclaw said flatly, "Soul nodes? Memory nodes? Whatever, I just found some structure for stable memories."

"So, you also ... constructed this way?

"Yes, I'm just a memory of Ravenclaw, not a real person, not a ghost, not even considered as life, but the only emotions are real without being fictional."

"As for transferring consciousness, you can refer to Pact Magic." She said quickly.

Felix could only memorize it as well, and he duly asked one last question: "Madam, I would like to know, how far did the four founders truly advance their magic?"

Ravenclaw gave him an approving look, "Talking too much will only disturb you, what I can tell you is that we count ourselves as magical beings."

She glanced at the diadem that was constantly being washed by the massive magic, the mass of black air being churned to pieces.

"It's almost time." Lady Ravenclaw said softly, her form slowly fading away, but she still looked at Helena tenderly.

The glow on Helena's body became brighter and brighter, more and more holy, and a heartfelt joy spread out.

The temporary body constructed by magic had disappeared, and she reverted to the form of a ghost.

"May I hug you again?" She asked.

Lady Ravenclaw opened her arms, and the two somewhat illusory figures pressed together for a long time before separating.

In a swirl of magic, a blurred face rushed out from the diadem, but immediately shattered silently.

The Lady Ravenclaw grabbed the diadem as soon as she could - it shone brightly, as if it had been scrubbed clean and as good as new.

"I will recreate the diadem as your reward." She said to Felix.

"Lady Ravenclaw, you don't have to ..." he said hesitantly.

"It is not as wise as you think it would be, not when it can be given." Lady Ravenclaw said, her figure growing fainter and fainter while the diadem grew brighter and brighter.

She glanced over at Helena with a parting glance.

"It is somewhat unfortunate that I cannot accompany you on your journey." Lady Ravenclaw said that she is just a memory, and today she finished the mission that belongs to her and is going to dissipate.

Helena smiled and said, "I've got the courage to walk the rest of the way."

Lady Ravenclaw stared at her, and after three, maybe five, or ten minutes, she finally disappeared.

"Clang!"

The diadem fell to the ground and rolled twice.

"Take it, it belongs to you," Helena said.

The light on Helena's body grew stronger and stronger, and the restrictions left on her by the Ravenclaw lady before had disappeared.

Felix didn't even look at the diadem, he gazed at Helena and said with some difficulty, "I'm going to lose another friend today."

She floated up to him and her palm tried to touch his cheek, but her fingers passed through.

"It seems you've had your share of grief."

Felix was silent for a moment, "Let's get out." He held out his palm and let the diadem fly over with the diary, which he tucked into the ring.

The two of them walked out of the Room of Requirement, the light from her body quickly spread out, a soft glow illuminating the entire seventh-floor corridor.

"It may be too late, I have something to say to someone," Helene said.

"Do you need help?" Felix asked, knowing who she was referring to as 'someone'.

"Sure." She smiled at him, "We're friends, aren't we?"

Felix's wand made a blast and the window in front of him abruptly disappeared as he leaped from the window on the seventh floor with Helena in his arms, before landing lightly in the yard.

The next moment, Felix's voice instantly resounded through the castle -

"Baron, come to the yard, Helena has something to say to you."

The young wizards in the castle looked up, startled by the loud voice.

What had happened?

"Come on, let's go check it out," Harry said to Ron and Hermione, and the trio ran simultaneously.

Doing the same, were other young wizards who, full of curiosity.

It is the weekend, everyone is very free.

They ran towards the yard at the same moment.

But the fastest is still Dumbledore, he appeared very abruptly in front of Felix and Helena, his expression a little puzzled, but when he saw the white light on Helena's body, his azure eyes widened at once.

He looked at Felix, who nodded gently.

Another ten seconds or so later, a silver shadow passed through a wall and appeared in the yard.

It is Bloody Baron.

He looked as frightening as ever, covered in silver blood and carrying a huge shackle on his back. But his expression at the moment is one of unprecedented tension and trepidation.

Bloody Baron looked at Helena bathed in light, his mouth opened and closed, and stammered, "Congratulations, Helena."

One by one, the little wizards and professors, and the ghosts came from afar, and they stopped far away when they saw this scene in the yard.

The little wizards were somewhat puzzled, but the professors and ghosts had seen a lot, and they clearly saw the state of Helena.

Nearly Headless Nick, covered his mouth very empathetically, "Oh, my God."

The other ghosts also stared nervously at the center of the yard.

"Sir Baron, I'm about to leave." Helena said, "I was told to learn to forgive myself ... I'll give that to you."

"And what about you?" Baron asked, his body shaking constantly, "Will you forgive me?"

"I've hated you, but I'll try to forgive you, just from this moment on." Helena Ravenclaw said.

The light from her body exploded into a white, long phantom of a ladder, appeared. Helena's gaze lingered around, finally pausing on Felix for a moment, and she firmly stepped onto the ladder.

Her figure disappeared.

Felix felt dispirited.

"Felix, thanks, I know the person she was talking about is you," Baron said, and a clean white glow spread from his body.

"I didn't do anything." Felix shook his head.

A clamour erupted from the distant ghosts; what a day. Two ghosts freed from their bindings one after another!

Only those who knew the thousand-year grudge of these two ghosts could not help but feel a lot of emotions.

Baron did not resist the white light stirring in his body, and in a solemn atmosphere, his figure disappeared.

The young wizards looked at this scene dumbly, they did not know what had happened but knew that the ghosts of Ravenclaw and Slytherin, two houses, had disappeared forever from this day.
