Chapter 70 The person who once opened the secret room
"I mean, this diary contains some terrible past events. Some past events that were covered up, some past events that happened at Hogwarts School of Witchcraft and Wizardry."

Seeing the jargon appearing in the diary, Harry's body began to tremble slightly. He took a deep breath and quickly wrote in the diary.

"I'm right here at Hogwarts, and terrible things are happening in this castle right now, do you know about the Chamber of Secrets?"

Harry's heart was beating very fast, and he felt that he would soon learn the truth about the Chamber of Secrets from this 50-year-old diary.

In the diary, Riddle's notes became very scribbled, as if he couldn't wait to tell Harry everything he knew.

He told Harry about his experience in fifth grade. At that time, the Chamber of Secrets was opened once, and even a poor student died because of it.

In the end he caught the murderer, but in order to protect the school's reputation, the then headmaster of Hogwarts did not allow him to tell the truth.

The murderer was expelled, Riddle was asked to keep it a secret, and the school gave him a medal, and the matter was left alone.

After listening to him finish the story, Harry almost knocked over the ink beside him with excitement. He asked Riddle to tell him who was the one who opened the Chamber of Secrets last time.

But Riddle readily agreed, and invited Harry to take a look at his memory for himself.

Harry hesitated for a moment before agreeing.

Then Riddle took Harry to watch from his own perspective, the event that the Chamber of Secrets was opened 50 years ago.

Let him personally participate in the whole process of how he reported on Hagrid, how Hagrid let his "monster" friend escape, and was finally caught.

Harry returned to reality from Riddle's memory, he stared blankly at the front, breathing heavily.

The three of them guessed that anyone might be the descendant of Slytherin who opened the Chamber of Secrets, but they never thought that the person who opened the Chamber of Secrets was actually Hagrid!
When Harry was in a daze, the door of the dormitory was suddenly pushed open from the outside, scaring Harry nervously to close Riddle's diary.

Ron was wearing pajamas, with wet hair, looking at Harry strangely.

"what happened to you?"

Of course Harry wouldn't hide these things from Ron.

He couldn't wait to get up from his chair, and told Ron all about the conversation he had with Riddle, and what he saw through his memory that Hagrid was fired 50 years ago.

Ron's mouth opened wider and wider, and when he heard that Hagrid was expelled, he was already in a state of stunned.

"Wait! I've heard the name Tom Riddle before. Riddle was awarded a special contribution to the school 50 years ago."

He repeated a passage, and Harry looked at him in surprise.

"Where did you see it?"

Ron looked pained.

"It was because of this trophy. Filch took me away because I didn't wipe the trophy clean, and punished me by cleaning the trophy display room again."

From his words, Harry further confirmed that Riddle was telling the truth.

"It was because of exposing Hagrid that the school awarded Riddle the Special Contribution Award, so what Riddle said is true!"

Just when Harry and Ron wanted to continue chatting, the door of the dormitory was suddenly pushed open again from the outside.

Neville and Seamus, who were punished at Snape for handling potion materials, returned.

Both Harry and Ron shut their mouths in a tacit understanding, and then secretly hid Riddle's diary in their drawer.

Neville and Seamus looked tired, and neither of them noticed Harry's abnormality.

"Dean hasn't come back yet?" Seamus asked feebly what was going on with their other roommate.

Ron shrugged and said, "I just saw him next door. He seems to be showing off his new sketching quill."

Harry blinked his eyes, and expressed concern to Neville who was lying on the bed as if he had lost his soul as soon as he entered the door.

"What did Snape tell you to do?"

"Frog brains," Neville said with blank eyes, "the professor asked us to dig out a whole three buckets of frog brains. We have been busy since six o'clock, and our hands are covered with frog blood. Those dead frogs Reminds me of Lefe."

Harry and the others looked at each other, they knew that Leif was Neville's pet, Ron comforted.

"Don't think of Neville that way, Ryfe, it's a toad, not a frog."

But Neville didn't seem to hear him, because at this moment he was already snoring lightly on the bed, apparently falling asleep from exhaustion.

Harry and the others could only look at each other helplessly.

Early the next morning, during breakfast in the auditorium, Harry, Ron, and Hermione got together.

Harry told Hermione everything he had learned from Riddle last night.

Hermione and Ron, over and over again made Harry like a wheel, constantly narrating everything he saw in Riddle's memory.

Harry was a little tired of talking about it, and he even regretted knowing these things from the diary.

"Riddle may have found the wrong person," Hermione said weakly on behalf of Hagrid, "maybe another monster hurt someone"

"There are so many monsters in Hogwarts." Ron obviously didn't think Hermione's explanation was very reliable.

"We already knew that Hagrid was expelled, and he always liked to raise some big guys, like Lu Wei and Norbert."

Harry also wanted to find a reason for Hagrid, but he was distressed to find that he couldn't find it at all.

"And after Hagrid was fired, the attack stopped, otherwise Riddle would not have won the award."

Hermione said tentatively.

"How about we go to Hagrid and ask him about what happened back then?"

"How do you think we should talk?" Ron said, spreading his hands. "Oh, hello, Hagrid, have you released your furry, savage and terrifying friend recently?"

"Then what do you think Hagrid should answer us?"

Both Hermione and Harry fell silent.

In the end they decided not to go to Hagrid, nor to tell anyone about it, as if they didn't know about it.

At the same time, Harry and the others also stopped their investigation of the heirs of Slytherin. What happened to Hagrid made them subconsciously not want to face these things.

And under the care of Professor Sprout, the mandrakes in the greenhouse are gradually maturing. When they are fully grown, those who have been petrified will be saved.

The calm in the castle lasted until the next week, until Harry and the others were in Defense Against the Dark Arts class, and another accident happened.
