Struggling to survive at Hogwarts

"We consulted almost all the records in the library related to the secret room, which mentioned..."

"In addition, we also discovered..."

As Hermione spoke, she took out the shrunken notebooks from her bag and passed them around for everyone to read.

Draco looked at the densely filled notes, and although he was surprised by the other person's dedication, he still maintained his arrogant demeanor.

After Hermione finished speaking, Daphne, at Thea's prompting, asked her own question: "Miss Granger, besides the information you found in books, do you have any guesses about what the creatures or mechanisms in the Chamber of Secrets might be?"

Hermione remained calm and composed, saying, "Our guess is more inclined to be that of a special magical creature. The fact that it has survived to this day indicates its long lifespan, and the fact that it was able to escape unscathed after the attack suggests that it is good at hiding and agile."

After hearing Hermione's guess, everyone whispered among themselves, discussing the possibility of what Hermione had said.

Seeing that no one raised any objections, everyone lowered their heads and wrote down Hermione's guess on a piece of white paper.

"Then how should we defend against the next attack? After all, not everyone knows the Ironclad Charm," Zabini also raised his question.

Upon hearing this, everyone discussed among themselves, suggesting, "Why don't we gather all the young wizards together and have them move around together, whether it's during get out of class or not?" Theodore offered his idea.

“…This might be a bit difficult,” Harry said hesitantly, speaking for the first time, but still firmly stated his thoughts: “Although there have been three attacks so far, many young wizards do not think they will be the next target. Even if we urge everyone to be careful, no one will take it to heart.”

“Indeed, without the professors and others intervening, no matter what we do, not many junior wizards will listen to us,” Hermione said calmly.

Seeing that this idea was ruled out, the discussion reached a stalemate.

Suddenly, Draco looked down and saw his bracelet.

In a flash, an idea formed.

"Or, use self-defense tools?" Draco muttered to himself.

“This…” Daphne hesitated. “This method is good, but it’s too difficult. Are we going to prepare a self-defense tool for every young wizard in the school? That would be too costly!”

“No, no, no, my idea is that we make them ourselves! As long as we store a few Ironclad Charms in the bracelet, we can at least hold out for a while in case of danger!” Draco continued, his face full of confidence.

“Draco’s idea is feasible,” Thea suggested. “Although the method is somewhat cumbersome, it’s still a good approach!”

At this moment, everyone's eyes turned to Thea. Thea didn't hesitate and continued, "Perhaps we can also add an alarm to the bracelet. Once the Ironclad Charm is released, a signal will be sent out the next second, and the professors will be able to sense it immediately!"

"Great!" Hermione was quite excited, clearly indicating that she approved of this method.

Thea looked around. "Shall we raise our hands and vote on the idea of ​​the defense bracelet?"

The next moment, everyone in the room raised their hands in unison.

“Okay, then the defense bracelet can be added to our action team.” Thea wrote it down on the white paper.

"During the discussion just now, something suddenly came to mind," Thea put down her pen and slowly shared her thoughts.

"In all these years, has there never been a precedent for a locked room being opened?"

“I don’t think so,” Thea said, turning her gaze to Harry. “Potter, do you remember? On the night Colin was petrified, in the hospital wing, Dumbledore said something…”

The original quote was: "The secret room was opened once again."

Harry had a headache; it had been several months since Colin was petrified!

Seeing Thea's confident demeanor, Harry seemed to recall the words, "It seems... Dumbledore did say that."

Upon receiving Harry's confirmation, the people present were all quite agitated!

"It's been opened again? That means the secret room has been opened before!" Ron exclaimed.

"The Chamber of Secrets would say that if Dumbledore had said that, it's very likely that the last time it was opened was when Dumbledore was still at the school!" Theodore analyzed the last time the Chamber of Secrets was opened.

“But… if the secret room was opened, why didn’t we find any relevant records?” Pansy pointed out the suspicious point in one sentence.

"I swear, there is absolutely no record of the secret room being opened in the library!" Hermione said anxiously.

“Don’t worry, Granger,” Thea reassured Hermione, a glint of insight flashing in her eyes. “Perhaps we’re investigating in the wrong direction.”

"Think about it, it's known that the locked room was opened by someone! Maybe they already found the culprit who opened the locked room!"

"And at Hogwarts, where can one find a list of students who have been punished or a list of professors in office?"

No sooner had Thea finished speaking than Harry exclaimed excitedly, "Filch! George and Fred mentioned to me before that he has a huge list of students who have been punished!"

Thea gave Harry a satisfied look, indicating that he was a promising student, and everyone else immediately realized what was going on.

“It really is Gryffindor…” Zabini exclaimed.

"Yes, Potter is right!"

"But besides the list of students who have been punished, perhaps the trophies in the prize display room can also provide us with clues."

Seeing the puzzled looks on everyone's faces, Thea didn't keep them in suspense and simply said, "Since there's a murderer, there must be a hero who can uncover the truth! Such a noble act will definitely be rewarded by the school!"

"As long as we follow the timeline and investigate from the nearest to the furthest..."

Thea said no more, because everyone knew what Thea meant.

"really!"

"We never thought of that before!"

"Thea is amazing, she came up with such a great idea."

Seeing that everyone agreed, Thea raised her hand, signaling everyone to quiet down.

"Now, I'll assign the tasks:"

Potter, Weasley, you are in the first group, responsible for searching Filch's list of punished students, preferably making a copy, from 1892 to 1990.

Daphne, Pansy, you are in the second group. You are responsible for collecting the awards in the prize display room, removing those with specific reasons or unrelated to the secret room, and compiling the remaining list, which covers the period from 1892 to 1990.

Theodore, Zabini, Granger, you are in Group Three. You are good at analyzing information, so you will be responsible for filtering the suspects from the list and assisting them in obtaining the initial list.

As for Draco and me, we were in the fourth group, responsible for making protective items. Draco had a background in alchemy, so he worked with me to make them.

As for the distribution of protective items... it will start with the lower-grade members of the study group, ostensibly as... a reward for knowledge sharing!

What do you think of this arrangement?

Everyone shook their heads, indicating that they had no objections.

"Great! Then I wish us a pleasant cooperation!"

"A pleasure doing business with you!" x8
