The Entrance to the Chamber of Secrets

Most Ghost are happy to discuss death, which is why Wizet asked that question.

"You're a good conversationalist..." Moaning Myrtle's distressed expression softened considerably, and her tone even revealed a hint of pleasure.

She lowered her head slightly, pointed to one of the private rooms, and said with her head held high, "I remember it so clearly... I was crying in this private room..."

Snape said in an icy voice, "He's asking you how you died!"

"Terrible! You look like Bloody Baron!" Moaning Myrtle flew back to her original spot, her voice trembling with tears. "I just heard a boy talking..."

"I was so angry, I was thinking of coming out and making him leave, but then I saw a pair of big, bright yellow eyes, and then I died. You all bullied me! You all hate me so much..."

When she said her last words, she dragged them out, then rushed towards one of the toilets, sobbing, and disappeared again.

Wizet walked into one of the private rooms. "This is the place she was talking about..."

He tried to follow his usual steps and walked out of the cubicle again, "Assuming the boy entered the washroom normally... and then Moaning Myrtle heard the sound..."

Wizet looked ahead and fixed her gaze on the washbasin not far away.

The center of the washbasin is a cylindrical column that connects to the ceiling, with washbasins surrounding it.

Snape had already started, waving his wand and chanting, then shook his head. "I didn't sense any magic."

"The description is very subtle... It can't be triggered by conventional methods... Could it be Parseltongue?" Wizet frowned slightly, raised her wand, and Wand-Lighting Charm, "Lumos Solem!"

He carefully examined the details of the sink, from the drainpipes and basin to the faucet, and finally made a discovery.

On the side of one of the faucets, there is a pattern that looks like a scratch, resembling a snake.

After searching around, Wizet found similar scratches on the sides of other faucets.

However, these scratches are probably just a trick, because upon closer inspection, they are not as deep as the snake pattern.

Dumbledore returned to the bathroom, but Hermione and Ron did not follow him; they must have been taken back to their dormitories.

Dumbledore stood beside Snape. "Any discoveries?"

Snape shook his head. "I couldn't find anything. Maybe I need Parseltongue."

"The same thing happened back then," Dumbledore nodded in agreement. "We searched the place thoroughly with the Ministry of Magic, but we found nothing."

"Let's start here!" Wizet took a deep breath and hissed. "Open it!"

Dumbledore and Snape both noticed that magical fluctuations were emanating from the sink.

Snape grabbed Wizet's shoulders, pulled him back forcefully, and pointed his wand toward the sink.

The washbasins surrounding the cylinder were all moving, spreading out rapidly in all directions without making a sound.

The cylinder has disappeared, replaced by a thick, protruding pipe.

Dumbledore raised his wand, and a silver Phoenix flew from the tip of the wand and plunged directly into the pipe.

"That's a bad example," Snape said casually. "Unless you can change the appearance of your Patronus, it's best not to reveal the Corporeal Patronus."

Dumbledore shook his head helplessly. "Severus was right, I was careless... but just this once."

"I will remember this!" Wizet took out his notebook and wrote down what Snape had said.

He looked at Dumbledore and asked, "Headmaster Dumbledore, can you use your Patronus to investigate the situation below?"

Dumbledore waved his hand. "It's not really reconnaissance... but if Dark Magic exists, I can sense something amiss... and be prepared for an attack."

After a long while, he finally spoke, "Let's go down and take a look... it's deeper than we thought..."

"Okay!" Wizet and raised his wand.

Snape raised an eyebrow. "You're going down too?"

"Severus ...this is the magical world," Dumbledore began. "Danger always accompanies wizards...this applies even in times of peace."

"Think about it... brewing Potions can be dangerous, Quidditch can be dangerous, and the Care of Magical Creatures class can be dangerous... it's very difficult to defend against..."

"Water Separation Charm!" Wizet held his wand horizontally in front of his chest and flicked it upwards with a swift motion, and a huge bubble completely enveloped him.

The bubble shrank rapidly, like a thin film, and adhered to his body.

This is a little trick he developed by combining the Bubblehead Charm with Transfiguration based on the "Magic Cube Theory".

The original Bubblehead Charm was expanded to cover the entire body.

"See that?" Dumbledore's tone was cheerful. "Severus, you should relax... Besides, you need Parseltongue for the entrance, who knows if you'll need it later?"

"Then let's go down!" Snape raised his wand, tapped it on himself, and then leaped into the pipe.

Dumbledore shook his head and smiled, "Since Severus is so enthusiastic... if he's willing to go first, then I'll bring up the rear!"

"Headmaster Dumbledore, I'll be going now." Wizet braced himself against the sink and nimbly entered the drainpipe.

Inside was an extremely slippery pipe, surrounded by sticky, wet filth.

Wizet could even imagine what kind of smells he would have encountered and how much filth he would have accumulated on his body without the barrier of the Bubblehead Charm.

This is an extremely winding pipe, with countless other pipes extending out from it, leading to various parts of Hogwarts Castle.

Nevertheless, Wizet does not enter unrelated places because of those branching pipes, and still maintains a relatively stable speed on the bottom lane.

After a while, the steep downward pipe leveled out, and a ball of Wand-Lighting Charm light appeared not far away.

Snape appeared in a cave tunnel, holding a glowing wand, and crouched down to pick up the crumbs on the ground.

"Lumos Solem!" Wizet lit his wand and saw the ground piled high with tiny bones.

These skeletons were incredibly diverse; you could see not only rat remains, but also frog and snake skeletons...

Everywhere you looked, there were pale, bone fragments.

These bone fragments are quite old; they would easily turn to powder if you stepped on them.

Wizet stood up, raised her wand, and looked around.

The cave tunnel gave him a familiar feeling, reminding him of the Pensieve room.

Wizet immediately used her Magic Eye and saw that the surroundings were filled with Ancient Magic Power.

He carefully explored the mountain tunnels, illuminating the map in his mind.

Dumbledore and Snape were also studying the cave tunnel. After Wizet finished collecting the Ancient Magic Power, Dumbledore waved for Wizet to follow them forward...
