"You mean, the location of the vault is just below the castle? How do you know? Myrtle asked, a little incredulous at William's words.

"It's just a possible speculation, as far as I know, there have been many searches for the Chamber of Secrets in Hogwarts' long history, and the Headmaster would have hired knowledgeable historians to search for the Slytherin Vaults within Hogwarts.

But they found nothing, so I speculate that the Chamber of Secrets was probably hidden underground by Slytherin, which is the most overlooked place.

Everyone thought that the Chamber of Secrets would be a secret room inside the castle, but they would not have thought that the Chamber of Secrets was not inside the castle but underneath it. ”

"That's why you told me last time you wanted me to explore along the Hogwarts pipeline?" Hearing William's analysis, Myrtle's expression finally changed.

"Well, Slytherin's chambers can't have been built underground out of thin air, and if that's what I thought, there must be a passage between the castle and the chambers, and Hogwarts' intricate plumbing structure is the only place I can think of. They are also very old. ”

William explained his analysis to Myrtle, even though he knew that the entrance to the secret room was in the girls' bathroom where Myrtle lived.

But there was no way he could discover the Chamber of Secrets for no reason, in that case, what would Dumbledore think, wouldn't he wonder how William had discovered a Chamber of Secrets that no one had discovered for centuries?

Then how should he explain to Lao Deng.

Therefore, he had to lay out a process of discovery for himself that could stand up to scrutiny.

Moreover, in William's plan, he was actually not going to enter the secret room according to the entrance of this original book, after all, he didn't know snake language, and naturally there was no way to open the secret room alone.

"Have you ever asked the resident ghosts of the four academies? If that's what you say, then the ghosts who have lived at Hogwarts for centuries know better than I do, and they must have visited every corner of the castle. Myrtle asked with some confusion, and she immediately asked the most critical place.

From this point of view, the ghosts are more simple-minded and emotional, but they are not stupid at all, and if they are deceived as undisguised as fools, then they will definitely detect it unless they are already a little delirious like Professor Binns.

Tom Riddle also deceived Ms. Gray through rhetoric.

"I asked Nick, who was almost headless from Gryffindor, you know, we have a good relationship, Nick does seem to know something, but for some reason, he doesn't want to tell me the whole thing.

He simply encouraged me to search the castle for information about the Chamber of Secrets on my own, as if he was expecting me to discover them myself. It was Nick's vague words that made William realize that the world might be more complicated than in the books, and that the Slytherin Chamber of Secrets probably had more than the Basilisk in it.

"That's why I wanted your help to search along the pipes inside the walls, after all, it's easier for you to explore after becoming a ghost."

"I'll explore along other routes, and this is the first time anyone wants me to help him."

"I'll go back first if there's nothing to do, and I'll be here at this time next week, and you can tell me about the progress of Harry and the others and your exploration under the castle."

With that, William stood up, waved goodbye to Myrtle, and walked towards the outside of the classroom.

It seems that Myrtle will probably take a while to discover the secret room beneath the castle, but that's okay, there is still a long time before the end of this semester, and he has plenty of time, so he just needs to be patient for now.

On the Savior's side, they seem to have borrowed the book in the forbidden section through Lockhart's approval, and Lockhart is such a fool!

They too, they swaggered to take the copy of "Powerful Potion" from the forbidden book section, and now Dumbledore must know what the tricks they are doing.

Do you have any chance to gain any benefits?

If they pretended to stumble upon their secret little secrets, would they agree to borrow this "Powerful Potion" for the sake of secrecy?

In the hallway, William was silently thinking in his mind as he walked in the direction of the Ravenclaw common room.

For the resources in the forbidden book area, William has been greedy for a long time, and William has not seen this book in the family collection of "Powerful Potion", probably because he does not pay much attention to potions books.

Write a letter and ask your father if he knows what the book is about, and if necessary, copy it, and then ask Jupiter to mail it back.

It's hard work.

"Looks like I'm going to have to go to Hagrid somewhere in the next few days." William muttered under his breath that he was walking down the same corridor he had encountered with Harry's trio the previous two days, and that he needed to pass through to find the stairs that were constantly shifting, and in fact he only had to turn the corner to see the stairs leading to the upper and lower floors.

As he passed the familiar corner, a petite figure slammed out of the corner, startling William.

Through the dim torches, William finally saw the face of the student opposite, and after seeing the fiery red hair, William was even more frightened.

Damn it! That's Ginny Weasley!

Ginny didn't seem to expect a student to pop up around the corner of the hallway, and she staggered back several steps, her face full of face

Gan! Who the hell is the two of us scaring whom!

Seeing this scene, William complained wildly in his heart.

Keep a diary, you play it for me!

At this point in time, Ginny Weasley is definitely synonymous with danger, and the diary has completely controlled the girl's mind, and you can't tell when Ginny's own will is and when the diary is controlling her body.

William looked at Ginny on the other side very vigilantly, his right hand reached into the left hand side of the cloak, his wand was there, if Ginny moved slightly, then William could definitely pull out his wand and fight back as soon as possible, his heart quickly went through those spells commonly used in duels.

And with this action, the atmosphere in the corridor also became tense all of a sudden.
