On Halloween night, instead of going to the lobby for dinner, Bernard sat alone in his office, with a delicate teacup, his eyes glued to the table, on which was a piece of parchment, the map of the living spots.

This map was acquired by Bernard from Filch a long time ago, but it has not been used before, but now, this map will be of great use, and Bernard has been looking forward to it.

……

"Oh! Harry, Dumbledore has booked a skeleton dance troupe! I really shouldn't have promised to go with you to Nick's death party! Ron yelled at Harry in despair. This made Harry a little overwhelmed, in fact, to be honest, Harry was also innocent, but he happened to meet Nick on the road after Quidditch training, and Harry really didn't know how to refuse Nick's kind invitation. I had to nod my head and agree to such a thing that didn't seem so pretty. Later, he was dragged to the office by an angry Filch, if it weren't for Nick asking Peeves to mess with him, he wouldn't have been able to run away so easily, although Harry felt that he had escaped safely because of the letter, but anyway, he promised Nick that he would definitely go.

"Hermione, you're going!?" Harry, who had been blamed by his friend, turned his head to Hermione for advice, and there was pity in his tone that he didn't realize.

Seeing Harry's pitiful appearance, Hermione said generously: "Of course, Harry, I will accompany you, the mentor gave me a vacation today, and, after I told the mentor that you were going to attend Nick's death party, the mentor also gave me three necklaces for me to give to you and Ron, you have to take good care of it, this is to be repaid, the mentor has been very poor recently...... You know. ”

After saying that, Hermione took out three cross necklaces from her pocket, and in the middle of the silver cross was a small red gem, Ron had never worn such a precious jewelry, and he was suddenly surprised and didn't know what to say.

"Why did Professor Rochefort want you to give this to us?" Harry took the necklace and said suspiciously.

"Well, the mentor said that the ghosts can be formed because they are paranoid enough or the conditions for death are special enough, and Nick was a court earl before his death, he will definitely invite a lot of ghosts from the outside, and we can't treat the ghosts outside with the same attitude as the ghosts in Hogwarts, they are more likely to be maliciously infected and will harm us, so the mentor has prepared this talisman." By the time Hermione finished speaking, Harry and Ron were all fine. Ron wanted to scream again.

Finally reassuring their friends, Harry and the three of them walked towards the underground classroom, the corridor that they usually pass through seems to have become unfamiliar, many ghosts are shuttling here, the corridor is lit with blue candles, shining on their faces looks eerie, Ron's teeth have begun to chatter, I don't know if it is cold or frightened, today's underground classroom is particularly cold.

They heard a terrifying sound, like a fingernail running across the blackboard, and the three Harry were so frightened by the sound that their little hearts skipped a beat.

Turning the corner, the three little wizards saw Nick, who was almost headless, standing at the door, and he greeted him with a sad face, "Welcome, welcome, my dear friend, it's great that you can come." With that, he took off his feathered hat and invited them in.

The scene inside was unbelievable, with hundreds of pale and transparent ghosts squeezing around the room, swaying across the dance floor to the sounds of music that gave Harry and them the creeps. Standing in the doorway, Harry's exhaled breath turned to mist, and the underground classroom was extremely cold, at this time, the amulet that Bernard lent them was slightly hot, and the heat emitted made them not so uncomfortable, and the ghosts who had stood beside them immediately stood away from them as if they were disgusting stinking.

Shaking the necklace around his neck, Harry proposed, "Let's go around somewhere!" ”

"Be careful not to pass through them!" Ron reminded nervously. Three young wizards walk along the edge of the dance floor, and they see several familiar ghosts: Barrow the Bloody of Slytherin, the Fat Friar of Hufflepuff, and Lady Gray of Ravenclaw......

Suddenly, Hermione exclaimed, "Oh no, it's not! Come back, turn your head around, I don't want to talk to a crying myrtle......"

"Who?! Harry asked hurriedly as the three little wizards quickly turned around.

"Weeping myrtle! She was always scary in the women's bathroom on the third floor. ”

"In the women's bathroom?"

"Yes, she's always throwing tantrums there, and there's water everywhere, and girls don't go to the bathroom on the third floor if they could. It's terrible to hear her scream when you go to the bathroom......" said the three little wizards as they moved quietly.

But suddenly, a goblin wearing a bright yellow party hat appeared in front of them, "Hello, three little ones! Peeves' tone was ill-intentioned.

"Hello, Peeves." Harry, the three of them greeted him cautiously.

"I just heard you guys seem to be talking about crying myrtle?!" Although it was a questioning tone, Peeves had an affirmative expression on his face, and seeing the evil smile on his face, Harry hurriedly spoke, but it was too late.

"That's not polite to her! Isn't it, myrtle, crying myrtle! At first, Peeves was able to speak normally, but suddenly he screamed at the last sentence.

"We didn't speak ill of her, even if you called her...... Oh, myrtle! Hermione wanted to defend herself, but Peeves' voice was too loud, and the Lord had already arrived.

"Are you looking for me?" Myrtle spoke with a nervous feeling, tilted her head and looked around, her eyes went from Peeves to Harry, and then stopped at Harry, which made Harry very depressed, and it wasn't what I said about you, leaving Harry's little depression aside, Peeves didn't think it was a big deal to see the excitement, and immediately spoke: "Myrtle, I heard them say bad things about you again." Then Peeves floated backwards like an actor leaving the stage.

"Myrtle, listen to me, we didn't say anything bad about you, don't listen to Peeves." Hermione's face was not red and her heart was not beating and she was lying, and Harry turned her head in surprise to look at Hermione as if she was meeting her for the first time.

Perhaps it was Harry's actions that alerted Myrtle, who exclaimed excitedly, "No, no one likes Myrtle, you liars." Myrtle then seemed to try to get through Ron's body, but as she rushed towards Ron, a blinding white light erupted from Ron's chest, and Myrtle flew away screaming as if she had been violated.

Looking at the disgusted gazes of the other ghosts, Harry and Nick hurriedly said hello and ran away.
