Parvati has clearly reached a dead end. Ravenclaw's lounge was naturally not open to Gryffindors, not to mention that she still couldn't figure out the trick of the knocker, if she was as good-tempered as the fat woman, she might be able to sneak in until Filch left from the seventh floor. But if this is a knocker, there is no quirk......

For example, if you show off your high voice or like to recite school rules, Parvati will probably have to report to the principal's office tonight.

But if you run back at this point, there is only one road backwards, and it is very long! In case of a narrow encounter with the pursuing Filch along the way, even if Parvati is a brave man destined to defeat the Demon King, he probably won't be able to win.

For a while, even a tendon Parvati would be in a vague dilemma. Although the meow was clearly something that Mrs. Loris, and it was likely that Brandi and Hermione attacked her when they went upstairs, it was also possible that Peeves was just playing a prank. She wasn't sure if Filch was still persistently wandering around the seventh floor.

She didn't dare to go out...... So what to do now? Standing in the foyer and waiting? And then wait for that sleeping knocker to find out?

Oh, don't do that, that must be stupid...... Parvati, you're a smart girl~ Think of a way.

Parvati rubbed her forehead, thinking desperately in her head. But Parvati is Parvati after all~ The more desperately I think about it, the more blank my head becomes.

Woo, if only my sister was here! Padma is so smart, she must be able to... Shh Mom is so eccentric, why did she inherit all that little IQ to her! Didn't you just come out a few minutes later than me......

If I were as smart as a sister, I wouldn't be wasting my time here.

Huh? Younger sister! Parvati patted her smooth forehead lightly, and she had a flash of inspiration.

She reached out and fumbled in her robe, and somehow pulled out a small mirror, and she looked at herself in the mirror.

Same...... It's exactly the same! It's no wonder that even parents often call them wrong~ If Padma was standing opposite him, he would probably be considered the person in the mirror.

Such a me...... If you go to pretend to be a sister......

Hiss!

Rao was Parvati's nerves were thick and his ideas were simple, but he was still frightened by his slightly bold attention.

Although she claims to be her older sister, she does have to be born a few minutes early, but the sisters have always been the sister's decision...... And in terms of personality, my sister is much more serious (normal) than herself. That's when my sister knows......

The only bit of dignity I have left as a sister!

Parvati cried and fell to her knees on the cold floor in a frustrated forward position.

………… Ban Yu,

That's right~ Anyway, it doesn't seem to have any dignity at the beginning! It's better to pit Padma and let her know that her sister can't be bullied casually!

After a while, she suddenly got up, with a dazzling smile on her face, as if the depressed expression just now was faked.

Since the robe has the school's emblem on it, you will definitely be seen through it at a glance if you go in like this. However, this is not difficult for Parvati, although she often can't keep up with the rhythm in class, and occasionally wanders in a daze for no reason, but unlike the Transfiguration class, she showed her talent beyond everyone early. Now she and Hermione are the only ones in Gryffindor who can turn a tree branch into a hanger! Even Brandi could only get a hook to grow out of the branch.

She pulled her wand out of her trouser pocket and tapped it lightly against her clothes, the fiery red badge on her chest embroidered with the Gryffindor House insignia slowly turning into a Ravenclaw sky blue after a violent fluctuation. The eagle above is spreading its wings.

Eh...... The bird's beak seems a little crooked? Hey, it doesn't matter, anyway, it's so dark that the knocker probably won't be too clear, right......

Thinking so, she tried to puff up her chest, imitate the intellectual and gentle appearance of her fish-lipped sister, cleared her throat, and pretended to be like the wind and walked in the direction of the knocker.

When she reached the door, the eagle-shaped knocker that she was sleeping on suddenly opened her eyes. A sharp gaze swept over Parvati's body, and she was stunned, almost showing her timidity.

"Is this, Miss Petyer? Why haven't you gone back to sleep in the lounge so late......" The door knocker made a dull mezzo-soprano, with a hint of tiredness in his voice, I really can't tell that such an upright eagle could actually be a female?

"Hey......" She just wanted to reflexively stick out her tongue and sell cuteness, and then realized that she should now be a lifeless Padma like an old woman, instead of a lively and cute Parvati. So she quickly changed her words. "Ahem, some private matters, go out for a while......"

"Oh? Personal? "The knocker always felt like something was wrong, as if I had seen Padma today, but there were so many people in Ravenclaw, and they came in and out so often every day, I really didn't remember it. It didn't pay much attention to the details, "Well, as a wise Ravenclaw, it's understandable that he is full of curiosity and curiosity about the castle at night." However, if you can, Ben Ra Ring still hopes that you will be able to come back early next time...... After all, the relentless pursuit of knowledge also requires a healthy body, and moderate sleep can do just that. ”

"Thank you for your advice." Parvati bowed solemnly, as if it were the case, if not counting the slightly raised corners of her mouth. "So can you let me in and rest now...... Staying up late reading books really affects my thinking, and I probably won't do it in the future. ”

"Okay...... Then it's official, Miss Petyer, even late at night, tradition is still tradition after all. The steps that should be there can't be ignored~ I know you're also sleepy...... Hold on a little though. ”

Shrimp?

The smile on Parvati's lips froze instantly......

What is the question part? How could Ravenclaw still have such a quirky setting?

She would have liked to ask what that meant, but apparently as a 'Ravenclaw', she shouldn't have that question. So she could only hold her little head, pretend that I was actually very strong, and listen to the question that the knocker gave her.

"What can extraordinary wisdom bring you?"

………………

Ah, how strange is that? Why can't I understand this link......

Parvati blinked, staring at the brass ring, as if trying to see the answer in the eagle's head.

"A simple question, isn't it, it's obvious ~ I've drained as much water as I can for a sleepy Ravenclaw! Just say one~ As long as it is a little logical and Ravenclaw temperament, you can count it as you. Of course, it's still the same~ If the answer is satisfactory to me, you'll be additionally favored by Ravenclaw. ”

………… No, I probably don't need that very much. Ravenclaw probably wouldn't favor a fool either.

Parvati looked at Hawkeye's expectant eyes in distress, what can extraordinary wisdom bring? Riches and glory? The answer that the knocker wants is certainly not this ...... For the first time, she thought that brains were a good thing, but she didn't seem to have them.

"Huh? Still thinking? Want to surprise me? Haha~ I don't hate hard-working children, Miss Petill ......" The door knocker turned sharply, "However, I think you may not have enough time, and your journey back must not be very peaceful." The shelter in the lounge is crucial for you. ”

Without the reminder of the knocker, Parvati himself could faintly hear the footsteps coming from the corridor in the distance. Filch, this guy......

She was starting to panic a little, and Filch's hideous old face was constantly circulating in her mind. She had already begun to make up for the indescribable horror of being taken to Filch's office full of torture instruments. Oh my God...... It's horrible.

She thought so, and muttered softly.

Parvati ...... You're in big trouble this time......"

She spoke softly, but she was still heard by the sharp knocker, and somehow the knocker suddenly cheered loudly, startling Parvati.

"Oh! Troublesome? Superior wisdom can lead to trouble...... Oh, my God! Very nice idea! That's great! Miss Petyer...... Oh, yes! It is not uncommon for people to be jealous of the geniuses who have won the crown jewel of the goddess of wisdom! Yes, we may be in big trouble...... But Miss Petyer, remember, as Ravenclaw, we are not afraid of all this! ”

Its tone sounded delightful...... The door squeaked open, revealing a fire-lit hole inside.

Parvati hadn't reacted to what was happening, but she reflexively slipped in, and the contented sound of the knocker came from behind her.

Quite an innovative answer...... Miss Petyer, as I am saying, you have won the favor of Ravenclaw! Congratulations, Ravenclaw's private collection will be open for you~ Pick a copy, and then take it back and study it well, it will be your life's treasure! Of course, you can only read it alone, and Ravenclaw knowledge will only be prepared for the most creative students. After this semester, you don't have to take it with you, it will disappear on its own, don't worry. ”

Yes? Parvati stared blankly ahead, blankly thinking about what had just happened. It wasn't until a long time later that it dawned on her that she seemed to have answered the question correctly. It seems that he is a fool and has a foolish fortune? What other rewards did you get?

In the Ravenclaw lounge, a transparent pale blue film of light hung down like a waterfall from the center of the star-studded dome, and gradually formed an illusion in front of Parvati, where there was a huge bookshelf, from the ceiling to the ground, densely packed with countless books, they loomed, swaying slightly with blue ripples.

Is this to allow yourself to take it from within?

Parvati hesitantly put her hand into the light film, which felt like it had reached into a pool of icy water, but there was no resistance. She couldn't read the words in those books clearly, maybe no one could read them clearly, which itself was probably a random process.

Anyway, I don't think much of this thing, so I just take it casually!

So Parvati picked out a big, rustic-looking book and pulled it out with all his might. The moment the book was held in his arms, the film of light shattered suddenly, bursting into a starlight in the sky, slowly fluttering in the Ravenclaw lounge, and then slowly disappearing after a long time............

Oh~That's pretty cool~

Parvati excitedly found a seat and sat down, she obviously couldn't run into the Ravenclaw girls' dormitory, in fact, she didn't know which one was the girl's, if she created the wrong room, according to her mother's words, she would have a needle's eye. But she naturally didn't plan to stay here for long, and it was a big deal to sneak out with the crowd when someone went out later. She just wanted to see what she had gotten now.

So she put the book on the table, and by the light of the fire, she could barely read the font on the cover.

For some reason, the author's column had turned into a pitch-black ink stain, as if someone had deliberately covered it. The title of the book is embroidered with gold thread with several flowered characters. The grammar and vocabulary seemed to be very different from what they are now, and Parvati read it awkwardly for a long time with that little knowledge of Old English, and finally reluctantly translated the title of the book.

"Natural Frequencies – Superposition of Magical Power ......?"
