After getting the Marauder's Map, Cyrus couldn't help but study it.

The results of the research by a few students were unexpectedly powerful, which made Cyrus sigh that students in the war years were different.

Look at what the students at Hogwarts are busy doing now? The prefects, who are role models, are actually in love!

And they were kissing in the ladies' room!

I'm talking about you, Percy! Cyrus stood at the door of the bathroom on the third floor. He had originally just wanted to see how the compound potion was being prepared, but now he narrowed his eyes as he looked at the man and woman who appeared in the women's bathroom.

"Gin-Ginny?" Percy's face flushed, and his hands bounced off Penelope's arms as if they were electrocuted. "You, why are you here?"

"Going to the bathroom - you?" Cyrus took a step back, turned his head to look at the sign outside the bathroom, and after confirming once again that this was the women's bathroom, he looked at the two lovers who had no future together as if nothing had happened.

"Dating in the girls' room? I really don't understand you. It's not like Hogwarts doesn't allow dating. Why are you doing this in secret?" As she said this, she looked at Penelope again.

"Penelope Clearwater. I'm from Ravenclaw - hello, Ginny -" Penelope was no better than Percy, her face was as red as if it had been dyed, and her lips trembled when she spoke.

"Hello, Miss Clearwater." Cyrus also greeted her. He just wanted the two lovers to stay away from the bathroom on the third floor to avoid any accidents at the critical moment.

"Listen, Ginny..." Percy seemed to have recovered from his nervousness and spoke immediately, "Can you please..."

"Keep it a secret?" Cyrus asked back.

The couple nodded immediately.

"You know what would happen if George and Fred knew about this..." Percy felt horrified just thinking about the scene.

They would definitely write letters to their mothers, and then hang countless banners in every corner of the school, saying: Congratulations to model student Percy for finding a girlfriend!

Or worse.

"Of course you can, but I suggest you go somewhere else," Cyrus said. "You are really the worst of you to hide in the girls' room. Don't you know that Ron often comes here? If he knew, then almost everyone in the school would know."

Hearing this, Percy's expression darkened even more.

"Thank you, Ginny. We'll, we'll go first then."

The two men ran away as if they were fleeing. Cyrus also heard Percy complaining to Penelope.

"I said it was not a safe choice to choose this place. I was discovered the first time I came here."

"Then find one yourself!" Penelope's voice sounded a little annoyed. —— "I just came over and saw Percy and the Ravenclaw prefect. Did you get caught?" Ron rushed into the bathroom and immediately looked at Cyrus nervously.

"I was discovered, but what's so strange about me being in the women's room?" Cyrus asked back.

"As long as the compound potion is fine." Hermione pushed open the last cubicle in the toilet. The potion in the crucible was almost formed. "Now we just need to add a little bit of Slytherin students' hair. It's best to add Goyle and Crabbe's hair."

She turned to look at Harry and Ron.

"That's true, but what about you?" Harry asked.

"I've got mine!" said Hermione happily, pulling a vial from her pocket and showing them a strand of hair inside. "Remember when Millicent and I wrestled in Duelling Club? She left this on my dress as she tried to get me by the throat! She's going home for Christmas - I just have to tell the Slytherins that I've decided to come back."

"Okay." Ron and Harry had no choice but to get Goyle and Crabbe's hair.

"By the way, Ginny, I'm going to the laundry room to steal some clothes. You continue stirring." Hermione said and rushed out. Cyrus had to continue stirring the crucible. Now black smoke began to come out of the crucible, and the whole compartment was obscured by the smoke.

"Luckily it wasn't smoking when Percy came over, otherwise it would have been discovered."

A moment later, Hermione returned with some cups and four sets of clothes, followed by Harry and Ron.

Hermione poured the bubbling potion from the cauldron into the cup, then added "Millicent's Hair". The potion began to boil like a kettle of water and foamed vigorously. A second later, it turned an ugly yellow color.

"Oh - the essence of Millicent Bulstrode," said Ron, eyeing it with disgust. "I bet it tastes terrible."

"All right, add yours," said Hermione.

Harry dropped Goyle's hair into the middle cup, and Ron put Crabbe's hair into the last. Both cups fizzed and bubbled: Goyle's turned a tank-like khaki, Crabbe's a dark, dark brown.

Cyrus also put the small bunch of white hair in his hand into the potion. In an instant, the potion turned into a color between black and white, but not gray.

"It looks awkward like this." Cyrus almost wanted to give up drinking the compound potion.

He should have taken a risk and used Transfiguration.

"Wait," said Harry, "we'd better not all drink here. Once we become Crabbe and Goyle, there won't be enough room here. And Millicent is not a petite person."

"That makes sense," said Ron, opening the door. "Let's each take a single room."

Cyrus chose a compartment that was a little off the beaten track. He originally wanted to simply pour out the potion, but in order to perform a perfect human transformation, he must have a considerable understanding of the details of the object being transformed.

The other person's height and weight, body proportions, details of facial features...

But he wasn't that impressed with Malfoy.

That's right, Cyrus planned to turn into Malfoy. He had decided this before. On the Thursday when he stole the potion, he pulled a handful of Malfoy's hair.

So he raised his head and drank the compound potion.

Surprisingly, it was not unpalatable, but it had a very weird taste, like sweet, but also bitter, a little sour, and seemed a little spicy, but no matter what, he had already drunk the potion.

The compound medicine began to work.

He felt as if something alive had entered his skin, surging constantly. It was like a snake was moving under his skin, tearing open the place where his skin and flesh were connected, eating his flesh! But this pain was fleeting.

The next moment, he saw his platinum bangs through his eyes.
