Harry listened for a few more moments, making sure the monster's voice had disappeared into the myrtle bathroom. He turned to Malfoy and said, "We need to find out the identity of the monster quickly, it is now back in its lair to rest, and I don't know when it will come out again." ”

The three of them entered the library smoothly under the cover of the invisibility cloak, and at this time there was no one in the huge library, not even the emaciated tyrant Madame Pince, who was probably in the castle like the rest of the staff.

"What's the name of that book?" Harry asked, lowering his voice.

Malfoy hesitated for a moment, but finally said the title of the book: "The Glorious Secret, I guess you can't find it on ordinary bookshelves, it should be in the forbidden book section." ”

Harry and Ron looked at Malfoy with a look of disdain, but Malfoy didn't care at all, and said disdainfully: "This is the inheritance of the big family, Wes, how many more things can your family get their hands on?" ”

Ron ignored him, and after a sigh, he went straight into the forbidden book area to find the copy of "Secrets of Glory".

It didn't take long for the three of them to find the copy of Secrets of Glory on a locked shelf.

Harry carefully slipped around the chain, removed the book from the shelf, and handed it to Malfoy to show if it was right.

Malfoy pointed to the glowing black sun on the cover and said, "That's right, I'm very impressed with this sun." Then he looked back at the crest of the book, "Yes, it's this book, by Corvinus Gaunt." ”

Ron shuddered involuntarily when he heard the last name Gaunt.

"Ron, what's wrong?" Harry was keenly aware of Ron's awe.

"The Gaunts," Ron said, "my dad told me to stay away from the people of this family when I was a kid, they were a bunch of inbred madmen. ”

Harry looked at Malfoy, who reluctantly admitted the book: "They're also known for their violent personalities in our circle. ”

Harry thought for a moment and took out the two-way mirror that Professor Capet had given him, if the book of the madman family members tried to control him with dark magic, he could be sober in the first place.

The three of them opened the book together, and with Malfoy's guidance, Harry quickly found information about the Chamber of Secrets.

"I found the Ancestor's notes in my family's collection, ah, it was the great Salazar Slytherin, and through his guidance I learned one of Hogwarts' deepest secrets......"

Much of the descriptions were full of praise for Salazar Slytherin himself, which disgusted Harry to read, but he had to read it carefully, because the Corvinos Gaunt had a habit of sandwiching important information into the hype and missing it if he wasn't careful.

"I used my family's wealth to become a school manager. Upon returning to Hogwarts again, I managed to find the vault that the great Slytherin had left in the castle, and all of his extraordinary magical achievements. Salazar Slytherin's greatest achievement was his study of bloodlines, and I found a mythical creature in his legacy......"

Calvin was in his office, rummaging through mountains of parchment manuscripts.

Behind him, Dumbledore and Snape watched Calvin search for information. Snape tried to push him several times, but Dumbledore stopped him.

"Severus, I remember you used to be very patient, especially when you helped me with things......"

"Albus, I suspect he already knew, and now he is deliberately delaying time."

"Found it," Calvin pulled out a few yellowed pieces of parchment from the pile of paper, "Seriously, I should have made an alchemical work and stored all this information in it." ”

Ignoring Calvin's whims, Dumbledore and Snape walked up briskly and looked at the parchment that Calvin had found.

】

Dumbledore could probably see that this was a manuscript of the ancient Greek archmage Plato, which recorded various information about Medusa in detail, but in the margin of the parchment, there was another person's handwriting:

"Medusa is so aggressive that I have an idea to breed a variant of Medusa that will kill a creature as soon as it looks at it. I already have an idea, but unfortunately the space here is too small for me to write. ”

The commentary is not signed, but there is a complicated monogram that both Dumbledore and Snape understand about who the owner of this monogram is—the dastardly Helpo.

Calvin took out a second piece of parchment, on which there were only Helpo's notes:

"I succeeded, I created the creature I wanted - just incubate a male egg with a toad for a month, and from the male egg you can give birth to the Medusa Super Variant, its eyes are lethal, it can be dormant, it is a natural enemy of spiders, and it has powerful fangs. Although it also has the fatal heel of not being able to hear the rooster's crow, I am already satisfied. I'll name this creature the Snake King, or ...... it."

-----------------

"The basilisk—" Harry said, breathless, pointing to the word, and flipped back to find a more detailed description of the basilisk, "The basilisk has lethal eyes, and you can't be wrong." ”

"Then let's hurry up and find it," Malfoy was a little excited, as long as he could catch the basilisk, the trophy engraved with his name would remain at Hogwarts forever for future students to see.

"Okay." Harry grabbed the book and mirror, covered the three of them with his invisibility cloak, and prepared to leave the library.

-----------------

"The identity of the monster is known," Snap said gently, "but where is the Chamber of Secrets?" ”

Calvin was about to say something when Professor Sprout burst into his office and said in a panic, "A student is missing!" Malfoy, Potter, and Wesley's two youngest children. ”

"The basilisk attacked again?" Snape, who had always been calm, was also a little unsettled, after all, it was the child of the woman he loved the most.

Calvin quickly opened the drawer and took out a folded piece of parchment, "Don't panic, I'll take a look." He opened the map and found the names of the four men on it.

Dumbledore was not surprised that Calvin had this map, and stuck his head out to look for it. Soon the two of them found the names of Draco, Harry, and Ron in the library.

However, they searched the entire map and couldn't find Ginny Weiss's name. This caused both Dumbledore and Calvin to panic a little.

"Does this map have the function of time regression? See where she was last seen? Dumbledore asked.

Calvin shook his head.

Ginny's name is not on the map. There were only three cases, and she shielded herself from presence, but this was simply not possible for a first-year wizard; She left Hogwarts, which was impossible, and all the doors and secret passages were sealed.

Then there was only one last possibility: Ginny Weiss in the Chamber of Secrets.
