In History of Magic class, most of the students were groggy and awake were whispering to each other.

"What the professor said was true, I found the medal in the medal room for the 1943 Special Contribution to the School, and the name on it was Tom Riddle. Quite a common name, there are a whole bunch of wizards named Tom in England. ”

Ron said to Harry, "I'm afraid it's hard to find out from this clue. ”

"I think we have to find the Chamber of Secrets first."

Harry said to Ron.

"It's hard, Harry, no one has ever found the Chamber of Secrets, not even Dumbledore."

Ron spread his hands.

Professor Luo Cheng said that if you want to get more information, you might as well ask the ghosts in Hogwarts...... Ron! Come with me after class to the scene where the cat was attacked, and I think I kind of guess I need to go there to confirm it. ”

When Professor Binns announced the end of class, the whole classroom came alive at once, and the students who had just dozed off woke up and continued to exchange ideas about the most popular topic of "secret rooms" in the school.

"Maybe you'll have to use vicious black magic to open that secret room."

"I've heard that some mechanisms have to be opened at a specific time and by special means."

"Also, I heard that the Bincy family once had a secret room, and if you want to open it, you have to smear the blood of most of the heirs of the lineage on the mechanism."

Harry and Ron rushed out of the classroom, and they trotted all the way to the top of the hallway where the attack had occurred. The scene before me was the same as that night, except that the petrified cat was no longer hanging from the torch stand, and on the wall where the words "The Chamber of Secrets was opened" were leaning against an empty chair - it was Filch's chair.

Harry noticed the top piece of glass on the wall, where about twenty spiders were crawling in a panic, seemingly eager to get out of a small crack in the glass. A long silver wire hung down like a rope, and it seemed that it was through this wire that they hurried up and fled out of the window.

"Harry, what are you looking at? Oh – it's the damn spiders. ”

Ron's face turned pale when he saw the spider.

"The spider is on the run." Ron muttered, "They're scared too?" ”

"Do you remember the water on the ground? Where did it come from? Someone mopped the floor. Harry said.

"Probably right here," Harry said, walking a few steps past Filch's chair and pointing to Ron, "parallel to this door." He reached for the brass spherical handle, but suddenly retracted his hand as if it had been burned by fire.

"What's wrong?" Ron asked.

"Because it's a girls' bathroom."

A voice came from behind them, it was Luo Cheng.

"Looks like you've finally figured out to investigate the first scene?"

"Uh, yes......"

Harry and Ron were a little nervous, for fear that Accounting Luo Cheng would track down the secret room before them.

"But in any case, you shouldn't go into the girls' bathroom at your age."

Luo Cheng said, "You are still young, I'm afraid you won't be able to grasp it." Although it is abandoned, there is a female ghost that is more troublesome than most living women, the weeping myrtle. ”

Then Luo Cheng ignored the big sign with the word "malfunction" written on it, pushed open the door of the girls' bathroom, and walked in with Harry and Ron.

This is the very dark, dreary place. Beneath a large, stained, cracked mirror is a row of stone pools with peeling surfaces. The floor was wet, and a few candle heads burned low on the brackets, emitting a dim light that made the floor gloomy. The wooden doors of the single rooms are peeling off in paint and covered with scratches; One of the doors had its hinges off and hung there wakily.

"Harry, go to the innermost private room and knock on the door."
