The Cauldron on the Toilet, Hermione and Ron's Night Roaming

Inside the private room was a crucible, a crucible placed on top of the toilet, with crackling sounds coming from underneath it.

The crucible contained clear water, with only a few small bubbles rising to the bottom, indicating that it had just been heated and was still being heated.

"Heh!" Snape seemed relieved, letting out a cold laugh. "A brilliant idea, using a toilet to prop up the cauldron..."

"It seems the user has some peculiar preferences. Wizet, take a look at what materials are used in the water tank."

Dumbledore and Snape made way for Wizet, who entered the private room, drew her wand, and cast Wand-Lighting Charm, "Lumos Solem!"

He picked up the transparent jars on the water tank. "Lacewing Flies, live leeches, Fluxweed, and Knotgrass ... it's almost certain that these materials are intended to be used to make Polyjuice Potion."

Snape seemed to be waiting for something, and asked somewhat casually, "Tell me why you came to this conclusion."

Although his expression was somewhat languid, he gripped his wand tightly in his hand and his body was in a vigilant posture.

Dumbledore, on the other hand, paced around, as if observing something.

With two incredibly powerful wizards present, Wizet felt less burdened and followed Snape's questions, explaining her thought process.

"Leech has the property of 'shrinking,' so it has a wide range of applications, but it is usually crushed into juice or a portion is extracted for use..."

"It's like Shrinking Potion; without leech juice that has been left to stand for more than a week, it can't achieve the effect of 'making the drinker smaller.'"

"But it requires the use of living organisms, which means utilizing the property of 'absorption,' which aligns well with the principles of Polyjuice Potion..."

"If we compare a person taking the Polyjuice Potion to a leech, he can transform into the appearance of the other person by 'absorbing' their hair."

"To make good use of the properties of 'absorption' and 'change'..." Wizet pointed to two transparent jars, "the Polyjuice Potion needs to be supplemented with Fluxweed and Knotgrass to be stable enough."

"Heh... brewing Polyjuice Potion..." Snape narrowed Snape eyes, a dangerous glint in them. "What secrets are you trying to uncover? Or... infiltrate somewhere?"

"Perhaps the corridor attack was too inefficient, so they planned to sneak into a Common Room to take out many people at once... This method was all too common more than a decade ago!"

Dumbledore was about to speak, a faint sound suddenly came from outside the abandoned washroom.

The three of them moved in unison, closing their mouths and gripping their wands tightly at almost the same time.

"There's no Powdered Bicorn Horn, and no African Tree Snake Skin Fragment..."

"I secretly asked Percy ... Polyjuice Potion isn't an ordinary Potions; these ingredients are controlled... So what should we do?"

"This is really troublesome... Let me think... Snape's private storeroom... That's the only place I can think of. He would definitely have both of these materials there!"

Hermione and Ron were talking outside the door, their voices getting closer and closer to the abandoned bathroom.

"Snape's private storeroom..." Ron's voice became hesitant, "You mean the legend of the Chamber of Secrets ... could it just be a hoax?"

"Think about it... it's been almost a month since the Halloween Feast, and there haven't been any attacks. Shouldn't we just..."

Hermione's voice was firm, as if she had made up her mind to do it, "But it's also possible that it's true!"

"If there really is Chamber of Secrets, and the monster Chamber of Secrets really does attack, what should we do? There are quite a few students from Muggle-born!"

The two entered the abandoned washroom, and Ron's voice became firmer, "I almost forgot! You're too good, I completely forgot about this. Let's steal it! We have the Invisibility Cloak anyway!"

"Stop saying that!" Hermione's voice softened, becoming somewhat hesitant. "Starting today, Christmas will be ready!"

"Touching..." Snape blurted out abruptly.

"Ah!" Hermione and Ron screamed, and the Invisibility Cloak they were holding fell into the water.

Snape wore a broad smile, a smile like a fisherman who had caught a fish. "Would you like some gingerbread? To dip in the Polyjuice Potion from the washroom?"

"By the way... I do have Powdered Bicorn Horn in my storage room... as well as African Tree Snake Skin Fragment. What do you think of sending them over as Christmas gifts?"

Hermione and Ron's cheeks turned the same shade, like the bright red of the rising sun.

"S... I... don't... don't... Vi?"

They could barely utter a complete sentence, only gesturing back and forth anxiously, sweat beading on their foreheads, and Hermione's eyes welled up with tears.

"Violating curfew and attempting to steal a professor's property, Gryffindor loses one hundred points!" Snape's expression suddenly turned cold, like a block of ice. "As a...reward."

Dumbledore stepped forward and said in a gentler tone, "Miss Granger, Mr. Weasley, why don't you explain why you're here? And why you're brewing Polyjuice Potion?"

Hearing Dumbledore's calmer tone, Hermione and Ron calmed down a bit.

Hermione struggled to catch her breath and finally managed to say a complete sentence, "Headmaster Dumbledore ... that's why we're brewing Polyjuice Potion because we want to investigate the truth Chamber of Secrets of Secrets."

"Tell the truth, Gryffindor will receive ten points." Dumbledore nodded and asked encouragingly, "Who is your target?"

Hermione glanced at Snape's cold Snape, then exchanged a look with Ron, and began to stammer again.

Dumbledore stroked his beard, murmured, and said, "Severus, I'll go out and talk to them."

"Whatever." Snape pouted somewhat displeased. "Besides... no need to thank me. I was just following School Rules and deducting points correctly."

"Of course I understand..." Dumbledore chuckled and led Hermione and Ron away from the abandoned bathroom.

The three had barely left the abandoned washroom when a plaintive voice echoed behind them, "Why do you always bother me? Why..."

Wizet and Snape immediately turned around, and in mid-air was a female Ghost in a school uniform, whose expression looked extremely gloomy.

It is the Moaning Myrtle, the Ghost that the Grey Lady and Wizet mentioned.

Snape raised an eyebrow, Moaning Myrtle stepped back, her face showing obvious fear.

As expected of Professor Snape!

Wizet sighed inwardly and asked, "Excuse me, are you Miss Myrtle Warren?"

The Moaning Myrtle was still somewhat afraid of Snape, and took a few steps back before nodding and saying, "It's me! It's been a long time since anyone called me that. You're much more polite than them..."

Snape frowned, crossed his arms, and stood to the side, raising his chin at Wizet as if to say, "You deal with this."

Wizet took a step forward. "Miss Warren, I heard before... that you... died... in this very restroom?"
