After class, Harry, Ron and Hermione walked out of the classroom, discussing the information they had just obtained from Professor Binns.

"I've known for a long time that Salazar Slytherin is a perverted old lunatic." Ron said with disgust.

Hermione was still sorting out the current information: "Professor Binns mentioned the monster in the Chamber of Secrets. No one knows what it is, but Harry, we already have a direction."

She looked at Harry deeply.

Harry magically understood what he said. He quickly looked around and whispered, "You mean, my Parseltongue..."

Ron also looked at the two with horror.

"That's right!"

The three squeezed through the crowded corridor and soon came to the corridor where the attack took place.

The scene in front of them had changed a lot from that night. The accumulated water had been emptied, the petrified cat was no longer hanging on the torch holder, and the words "The Chamber of Secrets has been opened" were also cleaned up.

However, there was an empty chair against the wall.

"Filch has been standing guard here," Ron whispered. "He's been very irritable lately, and often finds all kinds of reasons to deduct points, such as talking too loudly or smiling frivolously."

"But this has nothing to do with us. We just need to check the scene to see if there are any clues we missed," said Hermione.

Several people acted quickly. Harry lay on the ground with his glasses almost sticking to the ground. He soon found the burn marks, and Hermione also found the spectacular sight of spiders lining up to escape the castle.

"What does this mean?" Harry was a little puzzled.

Ron stayed away from the spider, with a look of horror on his face: "This can explain a lot of problems - for example, spiders are afraid of that monster

." Hermione sorted out the clues as usual: "So, the one who launched the attack was a snake, and its characteristic is that its attack can cause petrification, and it is the natural enemy of spiders. This clue is already very close to the truth!"

The little witch said excitedly: "Give me a week, at most two weeks, I can find out its information. Ron, honestly, why are you shaking there all the time?"

Then Ron told the story of when he was a child holding a teddy bear, and the twins used poor magic to make the little bear have many legs, which made her giggle .

Ron said angrily: "If you have such an experience, you won't find it funny. Imagine that you are holding a teddy bear and calling its name, and then it suddenly sprouts many legs..."

"The water on the ground is gone." Harry said suddenly.

"Maybe someone cleaned the floor, such as Filch, that's his job." Ron said without thinking.

"But where did the water come from?" Harry intuitively thought that this might be a clue.

"Ah! I thought of it." Hermione screamed.

"What's wrong?"

"I thought of one thing, a possible witness, she lives next door to us, and may have witnessed the entire attack."

Following her gaze, the two boys looked at the sign for the girls' bathroom and swallowed their saliva together.

...

After dinner, they walked out of the castle and walked along the path to Hagrid's hut.

Along the way, they were still arguing about what happened during the day.

"In my opinion, we shouldn't go to the girls' bathroom. That Myrtle, and that place... It's a nightmare! And we were discovered by Percy." Ron kept chattering along the way.

"But we also know that she died fifty years ago. Before she died, she saw a pair of big scary yellow eyes. What does this mean? Those are the eyes of a snake."

Hermione ignored Ron's muttered "maybe not necessarily" and continued, "Your information is also very useful. We also know the name of Tom Riddle. He won the school's special contribution award fifty years ago. Maybe this is not a coincidence!"

Harry's eyes widened, "You mean, that Tom ended the previous successor of the Chamber of Secrets."

"That's right."

The three knocked on Hagrid's door, and he warmly welcomed the three little wizards in.

Ron was surprised, "Hagrid, your room has become clean."

Indeed, the three looked at Hagrid's room, and it was not a little cleaner. At least it was visible to the naked eye that the black floor had turned into a dark brown floor.

"Oh, you're talking about this," Hagrid said casually, "The last time Professor Happ came to visit me, he helped me clean up before leaving. It was very simple for him, just waving his wand."

"Professor Happ?" Hermione asked in surprise.

"Yes, Professor Happ. Dumbledore recommended him. He needs some advice on magical creatures. I'm an expert in this area, but he's not bad either. He's very insightful in some obscure areas. Yes, very insightful." Hagrid brought

a plate of crackers, a pot of pumpkin juice and three cups. He said proudly, "Professor Happ is an excellent wizard. I didn't have much contact with him when he was in school, but--" He pointed to a book on the chair, "Look, that's a gift he gave me!"

The three of them couldn't wait to open the book. Hermione found that this book was somewhat similar to the comic books of Muggles. Most of them were photos, and there was a short introduction at the bottom of each page.

"Are these magical creatures?" Ron asked curiously. This was completely different from what he had seen when he was a child.

"No, these are creatures from the Muggle world." Harry said excitedly, "Look, this is a lion, this is a giraffe - it has a very long neck, I've seen it in the zoo, this is a badger, it's a bit similar to the Hufflepuff logo, but they are definitely not the same."

Hermione was familiar with these animals. She had read the complete set of the Encyclopedia Britannica, which had chapters on animals. But the pictures in Muggle books don't move.

So Hermione asked, "Is this the book made by Professor Happ himself?"

Hagrid took a big sip of butter beer and burped crisply: "Yes, very attentive, right? I think I owe him a favor..."

After a long time, the three of them remembered their purpose.

"Chamber of Secrets? Heir? Monster?" Hagrid's face turned pale.

"Yes, we found some clues, fifty years ago..." Harry was about to introduce their findings, but was quickly interrupted by Hagrid.

"Listen, there is no secret chamber and no monster, it was just an accident!" Hagrid was a little excited and waved his thick hands, then his voice became smaller and he muttered: "It was really an accident, no one thought that something like that would happen, no one..."

Then the three were driven out of the hut.

"He's definitely hiding something!" Ron said indignantly.

"We can all see that."

The three returned to the warm common room, had to face reality, and began to rush their homework.

After a while, Hermione suddenly closed the book, scaring the two of them.

"Who do you think the heir will be?" Hermione asked them in a low voice, and seemed to be talking to herself.

"It must be a Slytherin. I guess it's Malfoy." Ron said quickly. Harry

immediately accepted this point of view, "Maybe it's really him. Think about it, his family has been pure blood for generations, he has reason to do this, and the most important point is that he has suffered a big blow recently-because of insulting Hermione, he was put in detention by Professor Happ!"

Hermione's breathing suddenly stopped.

Ron seemed to have found a theoretical basis, "Harry, you are right, it must be him, maybe the Malfoy family is one of the descendants of Slytherin, and they have kept this secret for generations... right, Hermione?"

At this time, the twins came over from a distance, "I seem to hear you talking about Professor Happ, has he done anything interesting?"

The twins sat on the left and right of Harry and Ron.

"Nothing." Ron said quickly.

Fred next to him hugged his shoulders with one hand and winked at the three of them, "Don't be like this, we can exchange information. We also admire Professor Happ."

George next to Harry smiled and said, "Yes, we admire him very much. We can't wait to take him apart and study his head carefully."

Fred sighed, "George, your tone makes it seem like we have some ill will towards Professor Happ."

"Really?"

"Of course not."

"At most, we-"

"Try to imitate his magic puppet." The two of them said one after another, and finally said in unison.

Harry thought for a moment, "Well, we went to Hagrid's hut in the evening and saw a magic book given by Professor Hep."

"What is it about?"

"Muggle animals, you know, Hagrid is fascinated by them."

"Cool!" The twins looked at each other and said in unison.

Ron said, "It's your turn. We agreed to exchange information."

Fred blinked, "Our little Ron has learned a lot--" "

--It's not easy to fool." George followed.

"But--who made you our brother." Fred made a joke as usual, and whispered, "We can provide information. You know, we are fans of Professor Hep. If any of you want to know his whereabouts, such as launching an encounter or something..."

Ron said in surprise, "You followed the professor?"

"Don't say that, we just got a little help, for example, Professor Hep has been going to the Forbidden Forest frequently recently." Fred shrugged and casually said a bombshell.

"Forbidden Forest?" Hermione said in surprise.

The three looked at each other.
