It took about twenty minutes for the diary to tell a story about a "young boy who encountered something unexpected".

When he was at school, he accidentally entered a room on the eighth floor of the castle. It was a huge storage room filled with the treasures of the young wizards of Hogwarts over the past thousands of years.

"I later inquired about it. According to rumors, they call this mysterious room the Flying Room or the Room of Requirement." The diary wrote, "I got that part of the information from here - it might have been hidden by a little wizard before me."

Felix raised the corner of his mouth and wrote in the diary: "So, you didn't find Slytherin's Chamber of Secrets, but another hidden room? You found Slytherin's research materials from the hidden room - the Room of Requirement?"

A few words quickly appeared in the diary, "That's it."

Felix tapped his fingers on the table and thought for a while. He wrote in the diary: "Those research materials are still in the Room of Requirement? You didn't take them away?"

"I think - this is the property of Hogwarts. Before I graduated, I put them behind a large cabinet with a bubbling surface, as if it had been splashed with strong acid. It was easy to find. I remember there was a five-legged monster in the cabinet that exuded a foul smell. There was also an ugly-looking wizard statue next to it." The diary wrote.

Felix pursed his lips and tried his best not to laugh out loud.

Interesting, really interesting.

The conversation between the two of them was like a complicated game, full of lies and misleading, all to see who was smarter.

Before this, Felix had never expected to get the hidden room of Slytherin's Chamber of Secrets from the diary. That was too unrealistic, and it was completely equivalent to revealing his identity as the "Heir of the Chamber of Secrets".

His purpose today was actually to try to find one or two hidden locations of research materials outside the school. This was also one of the possibilities he speculated, but the greater possibility was that Tom Riddle had destroyed all the materials - this was the result he least wanted to see.

Fortunately, the diary directly told him the room on the eighth floor.

It was worth his time and effort.

However, Felix also had a hunch that since the diary chose to tell him, it meant that it was not important information - at least not important to the Dark Lord.

But he still replied to the diary happily, "Thank you, Tom, I will verify it. If I misunderstood you, I will apologize to you."

"I hope so." The diary replied calmly.

Felix wrote with some regret, "People don't know what a brilliant era Slytherin's research results will create, so he has always been the evil image of a dark wizard. Tom, you did the right thing."

The diary did not reply, and the soul of Tom Riddle in it was about to explode.

And Felix added, "Slytherin and Gryffindor are simply two extremes. Godric Gryffindor himself is much more positive. He is fair, brave, and just..."

The diary poured out a line of text with a disdainful tone: "That's just an illusion." He asked a sharp question, "Felix Hep, guess, is it more killing caused by Slytherin, or more lives falling under the wands and swords of Gryffindor?"

Felix's expression was stunned.

The diary seemed to have anticipated his reaction. A line of deliberately bolded sentences appeared on the page. Just by reading the words above, one could see his mockery. "Yes, yes, history has always been distorted - Gryffindor is a butcher. More wizards died in his hands than the other three founders combined."

At the end of this conversation, the diary did not hide its malice towards Gryffindor. "With a sword in one hand and a wand in the other, he stepped on the corpses and became the best duelist of that era - this is Godric Gryffindor!"

...

Felix closed the diary, and his expression became unpredictable.

"Salazar Slytherin and Godric Gryffindor." He whispered the names of the two former close friends.

Felix certainly didn't think that the diary was telling the truth, but he didn't think that he would lie. Judging from his tone and wording, he was still somewhat credible.

"I need a guide, preferably someone who witnessed it at the time." Felix suddenly thought of a name.

Ms. Grey.

This beautiful but arrogant Ravenclaw ghost has another name - Helena Ravenclaw.

She is the daughter of Rowena Ravenclaw, one of the four founders of Hogwarts - this was originally a secret, and Felix learned about it by chance through the Bloody Baron. The

love-hate relationship between these two people can be written into a vulgar romance novel.

Felix pondered that although she was a generation younger, she was of the same era as the four giants of Hogwarts, and must know many secrets of the early days of Hogwarts.

On the other side, Harry tossed and turned in his bed in the dormitory.

Whether it was the news from Malfoy or Hermione's accidental intake of the Polyjuice Potion with cat hair, he couldn't fall asleep.

After midnight, Harry fell asleep in a daze, but he suddenly felt something stepping on his stomach, making him a little breathless.

He opened his eyes and saw a house elf with two big bat-like ears and a pair of protruding green eyes as big as tennis balls.

"Dobby!"

Harry screamed softly. He looked around and saw that the other roommates were still sleeping soundly.

...

The next day, Harry and Ron came to the school hospital early to visit Hermione.

Just last night, they took the Polyjuice Potion to get Malfoy to say something - they always suspected that Draco Malfoy was the one who opened the Chamber of Secrets.

But something went wrong halfway. Hermione's transformation object, Millicent, had a cat, and she mistakenly threw cat hair into the potion as Millicent's hair, resulting in serious consequences.

Her face was covered with black hair, her eyes turned yellow, and two long pointed ears stuck out from her hair.

When Harry and Ron walked into the ward, she was begging Madam Pomfrey to add a curtain around her bed.

"Did you get any clues last night?" She asked in a low voice so that Madam Pomfrey wouldn't hear.

"No." Harry said frustratedly.

"I'm pretty sure it was Malfoy," said Ron. "He wasn't telling the truth. He got mad at us when we asked him about the Chamber of Secrets, didn't he, Harry?"

"What's going on?" Hermione asked with great interest.

Ron explained, "We pretended to admire him - you know, it's difficult, Crabbe and Goyle are usually stupid. We asked him if he knew something? But he jumped up and warned us to shut up, otherwise he would show us something. I'm actually very curious about this."

Hermione sighed, and the long ears on her head drooped.

Harry glanced around and whispered, "I have some gains here. Last night, around the early hours of the morning, the house-elf named Dobby came to see me again..."

"Last night?" Ron asked.

"Yeah, you were asleep at the time." Harry shrugged.

"Harry," Ron frowned and said knowledgeably, "I have to remind you that house-elves are extremely loyal servants. Their obedience to their masters is almost engraved in their bones. I have never seen anything like what you said, this kind of -"

He couldn't think of an appropriate description.

Harry said, "He was eccentric, but I think he respected me, yes, respected me. He told me that danger still loomed over Hogwarts."

"And then?" Ron showed a hint of interest.

"And then he banged his head against the railings..." Harry said quite speechlessly.
