Filch seemed to have left the fourth floor, and the sound insulation of the door seemed to be quite good, and there was no such big movement inside that attracted people.

Of course, there is also the possibility that Filch feels that he can't do it alone, so he informs the others.

Smoothly back to the Gryffindor common room, the fat lady guarding the gate looked at the trio's drooping robes and sweaty red faces, and asked, "Where have you all been?"

"Don't ask! Pig nose, pig nose!"

Harry gasped and spoke, and the portrait spun forward. Harry and Ron stumbled into the common room, shivering and slumping into their armchairs, Neville walking last, undisguised worry written all over his face.

There was still a glimmer of embers in the fireplace, and the armchairs seemed to turn into black shadows, and Hermione sat on one of them, looking at Harry and Ron with frosty faces.

"You're back. Hermione snorted, "Look at the way you guys looked, won the duel tonight?" she accentuated the word duel, causing Harry and Ron to think of something bad, and their faces became more and more ugly.

"Malfoy lied to us!"

Harry's eyes were beating with flames, and he didn't know if the embers in the fireplace were reflected in his eyes, and he clenched his fist and slammed the armrest of his chair hard, "This vile, shameless, filthy coward!"

Hermione was slightly stunned, she didn't know that Malfoy had cheated Harry and them, but that didn't prevent her from lecturing Harry and them.

"I said it a long time ago, you ......"

"Shut up!" Ron interrupted Hermione angrily, "We're not sitting here to listen to you!" There was still a hint of fear on his face, and Ron felt his legs go limp just thinking of the three-headed dog.

Hermione's face turned blue with anger, and she pointed her finger at herself, and said, "Blame me? Did I let you go to that duel that was clearly a trap? Didn't I remind you with kind words before?"

"Good intentions?" Ron pursed his lips and said disdainfully, "You're just afraid that we'll be caught going out at night and deduct the extra points you get for answering questions in class...... Besides, when did you say that duel was a trap?"

Listening to Hermione and Ron's argument, Harry felt like his head was going to explode, there were so many things that happened that night, and there were countless changes and accidents. I wanted to sit here and be quiet for a while, rest for a while and go to sleep, but Ron and Hermione quarreled again, and Harry only felt tired.

"You're all quiet for a while. ”

Harry said helplessly, and he made a shut-up gesture to Ron, who snorted and turned his head away from Hermione. Harry looked at Hermione, then at Neville, who was sitting in the corner in a daze, gathered his thoughts, and said:

"We just accidentally entered the restricted area on the fourth floor. ”

"Forbidden area on the fourth floor?" Hermione said in a lost voice, "Have you all forgotten what Dumbledore said when school started?"

Harry rolled his eyes and said, "We didn't mean to, Filch was chasing us, and he ran into Peeves on the way, and there was no way to escape." ”

"Harry's is true. Neville suddenly spoke, "We really didn't go there on purpose. ”

Neville's words made Hermione, who listened to Harry's words and was skeptical, completely convinced, although she still wanted to take this opportunity to educate Harry and the others in their minds, but Hermione couldn't help but ask another completely unrelated question.

"What's in the restricted area?"

"A three-headed dog. Harry said, glancing at Neville and rejoicing, "If it weren't for Neville, we probably wouldn't be back." ”

Harry told Hermione everything that had happened in the box, including how Neville had knocked out the three-headed dog with two punches to get them out of the room safely.

To be reasonable, most of the things Harry said sounded decent, but when it came to Neville, the style of painting suddenly changed, and it suddenly jumped from non-fiction to fantasy novels.

Although, in Harry's opinion, it wasn't a fantasy novel.

Hermione half believed it, and then she looked at Neville, trying to get to know from him if the other half was real.

"Well, what Harry said is true, but ......" Neville scratched his head, a little embarrassed, "I'm not as handsome as he says." ”

Neville wasn't going to lie, so what Harry said was true, and Neville really punched the three-headed dog with two punches.

Hermione suddenly didn't know what to say, just stared at Neville's honest face in a daze, and the common room finally fell silent.

After a while, Ron couldn't help but ask, "What the hell are they trying to do? Lock up such a thing in school!"

"Who knows, maybe it's Professor Kettleburn's new pet?"

Kettle Burn, a professor of magical creature conservation, looks like a rag doll that has been ravaged by a brown bear, with only one arm and half a leg left on all four limbs, and many scars on her body. It was a respectable old man, brave and fearless, passionate about his work, and perhaps his only flaw was reckless impulsiveness. The more dangerous and aggressive creatures are, the more Professor Kettleburn likes them, and it would be not unusual to say that the three-headed dog was his own.

This should be the end of the matter, as the secrets of the exclusion zone seem to have been revealed.

"Well, there's a trapdoor under the dog's feet. "When I threw my second punch and landed on the ground, there was a trapdoor at my feet, which had been pressed down by the feet of the three-headed dog. ”

"What do you mean?"

"Meaning, the three-headed dog is actually guarding something!" Hermione said, frowning, obviously interested in the matter as well, but she was still stubborn, "But, that has nothing to do with us, does it?"

Neville nodded, Ron disdained to speak to Hermione again, and Harry hung his head thoughtfully.

Hermione stood up and said to the three, "If you don't object, I'm going to sleep." ”

"Oh, good night, Hermione. ”

Neville waved at Hermione, and when Hermione was gone, he couldn't help but yawn and said to Harry and Ron, "I'll go back to sleep first, I'm so sleepy =_= ah." ”

"Wait for me, I'll go back too. ”

When they were almost rested, Harry and Ron followed Neville, and the three of them went back to their cots. Neville and Ron soon fell asleep, but Harry didn't feel sleepy, as Hermione's words had left him deep in thought.

What is that dog watching......

What did Hagrid say?

If you're looking for something to hide, Gringotts is the safest place in the world - except for Hogwarts, presumably.

Harry felt as if he knew exactly what was inside vault 731, but, as Hermione had said, it wasn't about them, and those people would have taken care of it, wouldn't they?

But Harry was still a little worried, because the three-headed dog didn't seem to be as powerful as he thought, and if Neville could take it down, then so could others, especially for someone who could even hack and steal from Gringotts.

However, instead of these things, find an opportunity to teach Malfoy a good lesson, which is what should be done.
