A day at Hogwarts

Percy: "The Slytherin monster showed up again last night."

Tom: "???"

(Tom: Last night, I met a group of girls running wild on the way. I couldn’t take you to the secret room?)

Percy: "I didn't expect that Slytherin's pet was not a snake. I'm afraid history will be rewritten."

Tom: "What?!"

Percy: "Now the students of Slytherin House are very upset. According to the Slytherin pet that was seen yesterday, their school's emblem will no longer have a snake."

Tom: "Are you kidding me? What could that be?"

Percy: "Really, many people in the girls' shared bathroom saw it yesterday. Slytherin's pet turned out to be a huge jellyfish!"

Tom: "..."

Percy: "What I saw that day was actually not a snake, but the tentacles of the jellyfish!"

Tom: "..."

Percy: "So everyone thinks that the emblem of Slytherin House should be changed to look like a jellyfish."

Tom: "How is that possible!"

Percy: "Now everyone is discussing whether the 'descendant of the jellyfish' is male or female. If it is a man, it would be too despicable!"

Tom: "I'm so angry!"

…

No more words were displayed on the notebook. Percy thought for a while, closed the notebook, wrote a record of today's conversation on the parchment on the side, and handed it to Dumbledore when he went to have breakfast.

Percy was a little scared. He had mentioned to Tom that there was an Apparition class on Saturday night, so he seized the opportunity and controlled himself to go to the secret room.

But no one expected that when they reached the fourth floor, a large group of disheveled girls rushed out of the girls' collective bathroom, seriously disrupting Tom's plan.

In the cafeteria, the Slytherin students were ashen-faced. This incident had dealt a huge blow to them.

The emblem of the college is also the face of the students. Snakes are good, but now someone suddenly tells them that it should not be a snake, but the tentacles of a jellyfish. You should call it jellyfish academy. Who can resist it?

The twins who wish to remain anonymous got excited. Early this morning, from the Slytherin common room to the foyer on the first floor, all the candlesticks originally hanging on the wall turned into jellyfish-shaped chandeliers, with tentacles shaking there. .

Today's "Daily Prophet" was even more lively. A large number of former Slytherin House students posted testimonials overnight, and the newspaper was thicker than usual.

Charles is now in a low-key mode, and he didn't expect that the vent led to the girls' collective bathroom last night.

He could swear that he didn't look at the girls at that time. After all, they were all jellyfish, which meant they had no eyes.

Fortunately, no one took a wand to take a bath at the time, which gave him the opportunity to escape from the sewer to the lake, otherwise he would not know how this matter would have ended.

While eating breakfast, he was completely silent, which was in sharp contrast to the students who were discussing enthusiastically around him. He occasionally chimed in with a few words.

No one cared, just assumed he couldn't stop eating.

After breakfast, Charles was about to go to the Room of Requirement to practice those spells from yesterday when Harry pulled him back to the common room.

God knows where the kid had gotten a map of the castle. The places where the attacks had taken place were circled in red ink.

"I have a guess about the location of the entrance to the Chamber of Secrets," Harry said. "It should be in the bathroom or washroom."

Charles raked the rake and asked in a very affirmative tone: "Were you the jellyfish yesterday?"

"No!" Harry jumped up, "How could it be me!"

Charles nodded and said, "That's right. If you were going to the girls' bathroom, you would wear an invisibility cloak."

A friendly boxing match ensued between the two.

Everyone around them was surprised. The two guys didn't stop until Hermione came over with a stack of books that almost covered her eyes.

Hermione placed the book on the long table. The sound was quite heavy. She turned around and put her hands on her hips and said to Harry and Charles: "If you have the strength, why don't you help me find what kind of jellyfish can turn people to stone!"

The next moment, the two idiots entered the mode of back pain and leg cramps, rubbing their waists and legs while returning to their previous seats.

Harry pointed to the map on the second floor and said the new results of his research: "I marked all the places where monsters appear, and found that this place is a little special."

He was pointing to the bathroom where Myrtle usually resides, and continued: "From a time perspective, this is the place where monsters first appeared. The place where Mrs. Norris was petrified last year was in this corridor."

"There are stairs right here in the corridor. Last year, many people saw Mrs. Norris and us when they went upstairs. It is very convenient to go to the first floor foyer where Percy and the others were attacked from here."

Then he looked out where the others had been attacked, especially where Seamus and Cedric had been attacked, on their way back to the bathroom from where Justin and the Fat Friar had been attacked.

Harry finally said: "The monster appeared in the bathroom last night. I speculate that the vents in the bathroom on the second floor and the bathroom on the fourth floor must be connected to the secret room. If you follow the vents, you can definitely find the secret room."

Charles nodded, this reasoning made sense.

Hermione squeezed next to Charles and stretched her head to look at the map. After Harry finished speaking, she asked: "So how does the heir of Slytherin need to enter the Chamber of Secrets? It's impossible for that person to get through the vent, right?"

Harry thought for a while and replied: "Maybe it's like going from the Leaky Cauldron to Diagon Alley."

Hermione thought it made sense. Maybe the entrance to the secret room looked ordinary, but when needed, it could be opened by tapping a wand on a certain brick.

She rubbed Charles next to her with her elbow and said, "Aren't you very good at opening secret rooms? Why don't you give it a try? Maybe you can find it."

Charles was confused and understood that she was talking about the secret room with lightning and thunder that he accidentally opened last year.

"I don't think it's that simple." Charles shook his head. "Since it is the secret room of the Slytherin family, the method to open it cannot be too simple or too complicated. If it is too simple, others will accidentally open it. If it is too complicated, it will be passed down. If something goes wrong, no one will open it.”

"I think this method must only be related to blood, just like the Weasley family's secret room only recognizes hair color."

Ron came over when Harry was mid-sentence. At this time, he raised his head in surprise and asked Charles: "How do you know?"

Charles blinked and said calmly: "Guess."

Harry asked Ron curiously: "Does your home also have a secret room?"

Charles gave him a kick and whispered: "Is this what you should ask?"

Harry realized that he was being abrupt and shrank his neck and stopped talking.

Ron just said something like "My family is so poor" and it was considered vague.

Charles didn't care about this matter. When the old man was at Hogwarts, the vice-principal was named Weasley. It's impossible for their family to have some background.

The Potter family, on the other hand, didn't know if the property certificate of Harry's parents' house was still there.

Harry said to his friends: "I want to search all the bathrooms and bathrooms in the castle. Maybe I can find useful clues."

Charles nodded, patted his shoulder and said, "Very good, come on, young man."

Harry turned to him and asked, "Aren't you going to help?"

Charles looked regretful, shrugged and said, "I don't have time. Now that the weather is getting warmer, I have to deliver things to the centaurs again."

When he said that, Harry was at a loss.

Charles immediately slipped away and came to Professor McGonagall's office, preparing to write a note to the restricted book area to find books on making door keys.
