By the time the three boys had cleaned up and descended the stairs, Hermione was already sitting there in a serious manner, looking like she was in a normal position - she had slipped away from the poison she had done to Brandi earlier, and her face was still steamed.

"So, we can act?" Seeing Hermione, Ron couldn't wait to speak.

"Of course, the polyjuice decoction is already bubbling, and the book says that's what it should be when it's done." Hermione said. "It's Christmas, and all the people in the castle will be present in the auditorium at dinner, so it's the best time to do it, and I suggest we do it tonight."

"Hmm, do we have an event at noon?" Brandi was holding a small box from nowhere, and from time to time he grabbed a strange-shaped piece from it and threw it into his mouth, making a terrible gurgling sound. "If not, I'll probably need to get out of the way a bit, Harry, I need your cloak of invisibility - I'm walking down the hallway alone now and feeling a chill behind me, it must be Filch watching in the dark."

"No problem, but you wait," Harry agreed, but he quickly came back to his senses. "It's still daylight, what are you going to do with the Cloak of Invisibility?"

"No way...... I needed to make a trip to Room 13, where the entrance on the sixth floor was so obvious that I could only enter through the staff lounge. Brandi folded his hands helplessly, "I don't know what kind of madness Professor Dumbledore has ...... I said that there was something for me, and I had to hide it mysteriously. ”

"What Dumbledore gave you, hidden in Room Thirteen?" Harry closed his mouth in surprise, "Is it a Christmas present?!" ”

"I can't say that...... Do Christmas gifts need to be kept so secret? Isn't he a little crazy, you say......"

"Maybe it's going to be a particularly powerful magic item, or a spell book!" Ron's face was full of envy, "But it's also possible that there are cockroaches and moldy rat pills." Bill said that he had received a fang from Dumbledore that he had given him, saying that it was a good match for him to make his necklace...... You're right, he's a little crazy. ”

Only Hermione glared at Brandy.

"Don't forget if you don't like Lockhart, you still speak ill of Dumbledore!"

"Huh? You don't call him Gilderoy now~" Brandi pretended to be surprised, his mouth still moving. "Speaking of Hermione, how the hell did you break the crust cake into such small pieces and break it apart? This seems to be a good way to grind your teeth. ”

Hermione's expression immediately became quite exciting, she blushed and snatched the small square box from the dazed Brandi, then stomped Brandi violently, and ran into the girls' dormitory.

"What's wrong with her?" Brandi hugged his feet, his face full of puzzlement.

"I guess it's because you think of the cookies she made yourself as rock crust cakes......" Harry and Ron looked at each other and smiled heartily.

……………………

A few hours later, at the Hogwarts dinner, most of the people ate with gusto, including those who were secretly worried about taking the Polyjuice Potion later. Dumbledore didn't know where he got the interest to lead them to sing some of his favorite Christmas carols, which made the Sorting Hat lose its honorable title of soul-cutting hand.

Compared to the dry Sorting Anthem, Dumbledore's singing voice is more unique in terms of mental killing—not to mention that he has his own drummer, and Hagrid has drunk a few glasses of eggnog, and his voice is as loud as a drum. This made Draco Malfoy even more irritable, and he had to raise his voice and taunt Harry's new sweater in a loud voice. What broke his heart even more was that Harry was happily eating his pudding, not hearing a word of those rude and vicious words.

The Gryffindor's long table was filled with a cheerful atmosphere, but there were exceptions, and for some reason Brandy had a large bulging bag beside him, lying on the table with a sad face, which made him look particularly abrupt. Professor McGonagall walked up to him and questioned him.

"Are you going to study in the library today? It's Christmas! She looked at Brandi with concern and said softly.

"Huh? Ah, yes, Professor...... I'll go in a moment. Brandi said in a trance, his eyes still roaming back and forth between Hermione and Dumbledore.

He had already taken Dumbledore's gift back from Room 13, and from the first time he saw it, he had already confirmed Dumbledore's trick of stealing beams and changing pillars - but what Brandi couldn't understand was why he didn't plan to tell himself directly, but instead used such a curve to save the country, is this also cultivating his own ability?

As for Hermione...... That's all his problem.

He glanced at the other side weakly, and found that Hermione was still rolling his eyes, so he quickly lowered his head and ate the mashed potatoes in repentance.

He had just finished his third serving of mashed potatoes—he didn't dare to take anything other than the mashed potatoes in front of him. He felt someone tugging at his arm, and when he looked up, he saw that Hermione was gone, and Harry Ron was giving him a look.

So the three of them stood up and went to implement their plan.

"We also need something about the person we want to become." Hermione said lightly, as if she was sending them to the supermarket to buy laundry detergent. "But there's two of you — and a."

She glanced fiercely at Brandi's shoes. "You'd better think about who you're getting and what, and we're going to make sure we don't let them break into the Slytherin common room while we're talking."

The three of them glanced at each other, and Brandi said first.

"I'm probably going to need to go separate from you...... No, no, no, I'm not quitting, I still need Polyjuice Decoction. He looked at Hermione's gloomy face and waved his hand repeatedly, "But the plan needs to be changed, I've been to Room Thirteen in the afternoon, and it looks like Dumbledore wants me to help him with something else - it happened to be in conflict with our actions." ”

"Errands?" Hermione was stunned, and for a moment she almost forgot that she was going to have an awkward affair with Brandy. "What does Dumbledore want you to do? Will it be dangerous? ”

Brandi sighed and pulled the bag open a slit. The contents were revealed......

"The danger is probably not that dangerous, but it is a test of acting skills."

………………

"Can this thing really be drunk......

The four heads came together, nervously observing the pot, and the potion looked like a black, sticky slurry, like boiling a pot of asphalt.

"I'm sure I'll be fine with every part of the arrangement." Hermione flipped through Potions of Strength for the third time. "It's definitely a finished pot, and after we drink it, we take about an hour to look like another person. I've stolen Slytherin's clothes from the laundry room, and my hair is ready? ”

Harry and Ron lifted the thick, short hairs in their hands, which they had just cleverly exchanged for two sleeping pill-laced cakes from Crabbe and Goyle.

"But what do you do, Hermione." Brandi spoke, "Whose are you going to pull it out?" ”

Hermione pulled a small bottle out of her pocket and showed them a bright yellow hair inside. "Remember the Dueling Club? I lifted the fireball and accidentally pulled it off her shoulder as I struggled to pick her up. She seems to have gone home for Christmas—but I can say I've decided to come back again. ”

She picked up a long-handled spoon, scooped up the thick potion from the pot, and poured it into five glass bottles - although Parvati was probably just joking, but considering the amount of boiled up this time, Hermione chose to leave her a bottle, of course, if she was sure that the thing would suffer if she drank it.

Then, with trembling hands, she was the first to toss Millicent's hair into a glass jar that made a hissing sound like boiling water and bubbling with unsightly foam. After a second, it turns an unsightly yellow.

"Oh - I have a bold idea......" Ron's eyes sparkled with ill intentions.

"Shut up Ron, Hermione won't be able to drink it for a while!"

Brandi hurriedly covered his mouth, and Hermione's face next to him was blue, and it seemed that she could vomit at any moment.

Harry and Ron also threw their hair into the bottles, which turned earthy yellow and dark brown, respectively.

"What do you do? There are only three private rooms left for use...... Harry said hesitantly.

"Don't worry, I'll be out there...... I'll get dressed and call you later, and then you can open the door." Brandi added the contents of his hand to the bottle, and after a burst of bubbles, the potion turned a swirling silver-gray color.

"Oh, you should be looking good for this?"

"Pull it down, Ron......"

The three of Harry glanced at Brandi, then grabbed their clothes and slipped into the private room.

"Are you ready? Three, two, one—"

With a burst of glass shattering and a muffled grunt of pain, the lavatory returned to its former tranquility.

……………………

"Longbottom, clean up, someone saw you coming." Pomfrey's voice came from outside.

"Is it Seamus? Or Brandi? Neville sat up in panic, his face pale and about to close the curtain. Don't let them come! ”

However, a withered palm grasped the doorway, and a figure in a bright purple robe appeared in the small cubicle. Neville was confused for a moment, then he stared in surprise and stammered.

"Deng, Professor Dumbledore? Why are you here......"
