Dumbledore's tone was extremely sincere.

Harry was suspicious: "Really? ”

"Of course, the professors don't have that much energy, rummaging around every corner of Hogwarts." Dumbledore nodded, smiling slightly, "And this bathroom has been abandoned for fifty years, and very few people use it. ”

"We're not perverts who broke into girls' bathrooms right now."

Harry walked over to the faucet and expertly said in snake language, "Turn on." ”

A dazzling white light flashed.

The faucet twisted, like a snake, crawling to the left, and the root canal tugged at the pool, buzzing and vibrating with it, spinning and twisting open, revealing a circular door with a hole, of course, it was more like a pipe entrance.

"It's really here." Harry rubbed his face with a strange expression, "What did my Tom-senpai do to discover the entrance to the secret room?" ”

Dead.

When the Ravenclaws began to wander towards the forbidden book zone.

Hufflepuffs haunt the kitchen.

The Gryffindors pondered what to do.

Tom rummaged through one girl's bathroom after another.

"Alright, Professor McGonagall will take Mr. Potter back." Snape flicked his sleeves, "This is not the ...... he should have left behind"

"No, we still need Harry." Dumbledore interrupted.

Snape took out his wand and looked at him coldly, "You know what's down there!" ”

"But we might need a parseltongue as well." Dumbledore pulled out a thumb-sized crystal bottle from his robes, containing a shallow layer of crystal clear liquid, "Don't worry, I'm carrying Fawkes' tears." ”

Harry's eyes lit up.

Tears of the Phoenix.

A rare ingredient with strong healing properties, not on the prohibited list, but not even Diagon Alley for sale.

"Harry, do you want some?" Dumbledore noticed Harry's gaze.

Harry nodded, "Sure, as a reward for being forced to participate in this, how?" ”

The Witcher has always been "a thief who does not go empty".

"Then it's decided." Dumbledore waved his wand, and the effect of the spell fell on Harry and Snape, who turned his head to look at McGonagall, "Minerva, please keep watch here." ”

McGonagall nodded.

The three of them burrowed into the pipe, and the effect of the spell sent them slowly forward.

"Harry." Dumbledore spoke for more information, "I asked Lady Myrtle, the student who died fifty years ago, and she said that she had only seen a pair of yellow, lantern-like things, and then she died. ”

"Can you guess what?"

Couple?

That's the eye.

Yellow, look at each other and die......

Harry quickly found the corresponding name in the list of dark magic creatures: "It's... Basilisk? ”

Dumbledore nodded, "That's right. ”

"So be careful when you go down and close your eyes." Snape spoke, sneering, "Don't stare at your eyes like a brainless troll. ”

"You don't need to do anything."

"Dumbledore and I can figure it out."

"Can you leave me the skin, teeth, and backbone of the basilisk?" Harry requested.

"As long as you're honest." Snape immediately agreed for Dumbledore, "Don't trouble us, you can take those useless things back and do your kind of armor game." ”

"Thank you for your great kindness." Harry looked expressionless and complimented.

Snape snorted, tilted his head, and ignored him.

They landed quickly.

At the end of the water pipe is a natural grotto, damp, dark, and eeriely silent, without any breath of biological life, only ticking, ticking, and falling water droplets from time to time.

Snape waved his wand and lit up the light, illuminating the surroundings.

The ground was densely packed with bones, mostly small rodents, with occasional fish bones.

"Looks like our basilisk isn't eating well." Harry commented simply, "I've lived for thousands of years, and I can only feed my hunger with these things, tsk." ”

With a wave of his wand, Dumbledore rolled up the bones, threw them into the shadows, and led the way forward.

They soon passed by a flat field.

Harry stopped.

"What's wrong?" Dumbledore's expression was serious, and the magic began to coalesce in his hands.

Harry gestured, "There used to be something here, it was big, at least twenty feet long, and it had a faint magical aura. ”

"The basilisk rests here?" Dumbledore frowned, staring at the flat ground that he saw as almost indistinguishable from the rest of the world.

"No, it's supposed to be a snake." Harry shook his head, crouched down, and reached out to wipe the ground, "Just taken, the traces are very new, less than a day." ”

He looked up at Dumbledore.

"Or rather, at the beginning of a Quidditch match."

"He guessed that we would find the secret room, and he prepared in advance."

"We're going to get nothing this time."

Dumbledore frowned, "That's not good news. ”

They kept going.

They were almost out of the castle before they came to the end, a sturdy wall carved with two living stone serpents, their eyes made of shining emeralds, and the craftsmanship was so delicate that they were alive.

"Open." Harry uttered the word again in snake language.

The eyes of the two snakes flashed with a green glow, and they spiraled to the side, moving the stone wall away to reveal a wide passageway.

Inside was a hall, dim, cold, and tinged with a thick sinister aura.

Is it the smell of a basilisk?

Harry frowned, it was uncomfortable.

Dumbledore waved his wand, cast a spell on them, and gave them a layer of protection, and walked in alone, and after a long moment, he called out to Harry, "Come in, it's safe here." ”

The hall is bigger than it looks from the outside.

Thirteen pillars support such a huge structure, and on each pillar, a snake is carved, circling, entangled, and opening its mouth to hunt for food, each with a different demeanor.

and, at the end of the hall, the huge figure carved into the wall.

An old man with the appearance of a monkey, a sparse beard, and a robe that was so long that it looked a little ill-fitting.

"This is Slytherin?" Harry walked over to Dumbledore.

Dumbledore nodded.

"I thought he would look like Voldemort." Harry commented casually and took another step forward, "I'm going to try talking to him again." ”

"Maybe call the basilisk out."

Dumbledore raised his wand.

"Open!" Harry closed his eyes and read the snake language aloud.

There was a violent trembling movement in his ears, but nothing happened, only a faint aura of magic gushing out, and there was no other breath.

Dumbledore patted him on the shoulder, "There's no basilisk here. ”

Harry opened his eyes and looked.

Slytherin's mouth was wide open, with dark holes that took up nearly half of his face.

"Let's go in and have a look." Dumbledore waved his wand, and the three of them flew up and down Slytherin's mouth into the statue.

It is a room no smaller than the common room.

Dry and clean.

But it was empty, there was not a single collection of books on the shelves, and the cabinets where rare materials were stored were also swept away.

"Senior Tom has a really clean shave." Harry glanced at it, stunned to find nothing else of value, "I'm ashamed of myself. ”
