As I said, this matter was over, Lucius did not cause trouble for me, and Malfoy did not mention it again.

October is coming, and a wet cold air fills the ground and penetrates the castle. A cold suddenly pops up between the staff and the students, causing the head nurse Mrs. Pomfrey to be in a hurry. Her refreshing potion has the effect of seeing the shadows, but those who drink this medicine will smoke in their ears for several hours. Ginny Weasley has been sick recently and is forced to drink some refreshing potion by Percy. As a result, steam comes out from her bright hair, and her whole head looks like it is on fire.

"Discovery Party?" Hermione said with great enthusiasm when he heard Harry's help and invitation about Sir Nicholas, "I bet that few living people can say that they have attended such parties--it must be wonderful!"

"Why do anyone celebrate their deaths?" Ron said with anger, doing his homework for potions class, "I think it's so dull..."

"Maybe, but ghosts are different from us after all, and their death anniversary is actually their birthday." I said lightly, "If you really want to go, I advise you to wear more cold-proof clothes, bring some cold-proof potions, and prepare some food. After all, ghost food and living environment are not very suitable for living people."

"You seem to be familiar with these things, Lina." Hermione's interest shifted and she asked excitedly at me.

"I often lived here when I was a child. The professors were very busy at that time, and only ghosts were taking care of me. I still remember how they tried to make me laugh..." As I said that, I smiled slightly, which was a sincere smile.

Halloween is coming, and although Harry and the others regretted a little recklessly agreed to attend the death anniversary party, for the sake of these kind ghosts, we decided to go and take a look. So at seven o'clock, we walked straight through the doorway, which led to the crowded auditorium, where lights were decorated, candlelight shining, and gold plates were placed on the table, which was very attractive, but we still chose to walk towards the underground classroom.

The aisle leading to Sir Nicholas' party was already lit with candles, but the effect was not pleasant at all: they were all black, and the tiny little candles were shining with blue light when they burned, and even when they shone on the four of our lively faces, they looked gloomy. Every step they took, the temperature was lowering. Harry and the others pulled their clothes tightly and poured a bottle of potion into their mouths—it was a warm-up. At this time, we heard a sound, as if the sound of a thousand nails scrambling over a huge blackboard.

"That's also music?" Ron whispered.

"Yes for the ghosts," I replied faintly.

"My dear friend," said Sir Nicholas, dressed in a well-dressed manner, and said to us with infinite sorrow, "Welcome, welcome... I am so happy that you can come..."

He took off his feather-stuck hat, bowed and invited us in, we returned the gift and walked into the classroom of the party.

The scene in front of me was really unpleasant. The underground classroom was filled with hundreds of milky white, translucent figures. Most of them floated around the crowded dance hall, dancing waltzing with the terrible and trembling sounds of thirty braised chariots. The band playing braised chariots were sitting on the stage covered with black cloth. A thousand candles were also lit in a chandelier above my head, emitting midnight blue light. The breathing of the four of us formed a cloud of mist in front of us, as if we were walking into the refrigerator.

"Let's take a look around?" Harry suggested.

"Be careful, don't pass through someone's body." Ron said nervously. We walked slowly around the edge of the dance field, passing by a group of depressed nuns, a ragged man wearing chains, and a fat monk - this is the ghost of Hufflepuff, who is lively and pleasant, and is chatting with a knight with an arrow stuck in his forehead. We also saw Barrow, the Bloodman, Barrow, the ghost of Slytherin, who is thin and straight, his eyes are straight, and his body is covered with silver blood. Other ghosts are making a big room for him.

"Look, what to eat!" Ron said, pointing to the long table not far away.

"Don't go over, you won't want to see it." As I said, I pulled the three of them away from the long table, but Hermione still looked back and saw a huge grey cake in the center of the table, with tar-shaped frosting on it:

Sir Nicholas de Mincey Popington

Died on October 31, 1492

"This...I want to say, why are these foods so strange?" Hermione asked me.

"The ghosts actually have no taste, and they don't need any food, so they have to make the living people eat more delicious." I replied, "But I can only say that. I still want to eat later."

Seeing that I didn't want to say anything more, Hermione didn't continue to ask again. After a while, we met Sir Nicholas again.

"Is it fun to have fun?" Sir Nicholas said happily.

"Not bad," I replied lightly, "but Jazz, please allow us to leave early, after all, ghost parties are not suitable for living people."

"Oh, yes, you're right." The Jazz nodded and said apologetically, "Actually, I'm very happy that you can come. I'm so sorry, you'd better go to the banquet quickly, maybe you can catch up with the pudding."

After saluting to the jazz, we moved towards the door, while nodding and smiling at each ghost looking at us. After a minute, we hurriedly walked in the aisle with black candles.

"I really hope the pudding hasn't been finished yet." Ron said with anticipation while moving his hands and feet, leading the way to the foyer.

At this time, Harry staggered and stopped, grabbed the stone wall, listened with all his attention, looking around, squinted his eyes and searching up and down the dimly lit aisle.

"Harry, why are you-?"

"That voice came out again - don't talk for now-" Harry said urgently, Hermione and Ron were stunned, staring at Harry with strange eyes.

"Go here," he shouted, running up the stairs and into the hallway, where the laughter and joy of the Halloween banquet in the auditorium were echoing, and it was unlikely that other movements would be heard. Harry ran up the marble stairs at full speed and came to the second floor, and we followed behind.

"Harry, what are we doing-"

"Shh!"

Ron wanted to ask Harry what was wrong, but was quickly interrupted by Harry.

"It's going to kill!" Harry shouted, and climbed the third floor stairs regardless of the confusion on the other people's faces.

"Don't act rashly! Harry!" Just as Harry was about to walk out of the stairs, I grabbed him from behind.

"Let me go! He's going to kill someone!" Harry struggled, but I pressed it directly to the wall next to me.

"Then what can you do? Run over and let him kill another life?" I stared at Harry's eyes and said seriously. Then I took out my wand, silently said, stretched the wand out of the corner of the wall, then pulled it back, and then pointed it in the air. A picture suddenly appeared in the air in front of us. This was an image of the corridor on the third floor behind the corner.

"Impossible, why is there nothing? I clearly heard..." Harry said in surprise as he looked at the image in front of him.

"What are you saying? What do you hear or not? We hear nothing?" Ron asked strangely.

Harry looked at Ron and Hermione in surprise and asked, "You can't hear it?"

"It may be only you who hear it. Sometimes, some wizards will hear voices that others cannot hear." I answered Harry casually, but my attention was always focused on the picture in front of me. As my wand continued to move, the picture was slowly changing. Finally, the picture was frozen on a wall with some red words on it:

The secret room was opened.

Be alert if you are enemies of the heirs.

"What is this?" Hermione asked.

"The words written on the wall in the corridor." I replied, waving my wand to let the picture go away. I said to several people: "I don't know if there is any danger in the corridor ahead, so I have to go to the professors and the others first, but there must be no one to monitor here. You can wait here, don't act rashly - don't forget the incident of the monsters last year!"

After saying that, I quickly left here, came to the auditorium, found Professor McGonagall, and told her about this. The professor frowned, confirmed the place I mentioned, and then quietly told Dumbledore about the matter. Dumbledore did not announce the party to stop, but took several professors to follow me and left quietly.

"Where is Harry and the others?" When he came to the stairs on the third floor, Harry and the others were not here.

"They must have not listened to me, so they went out first." As I said that, I immediately ran out of the corner, and the other professors also ran out with me. We found three people discussing in the women's bathroom on the third floor.

I didn't care about the three people who were being scolded, but came to the row of red characters, first collected some "red pigments", and then cast a magic on the red characters. The first and last letters of the red characters suddenly flew out two round patterns, and the patterns were all together. I took out a piece of paper from my handbag and printed the pattern on the paper.

"Professor, it seems that the party will have to be held for a while." I said to Dumbledore.

"What? Have you found anything?" Dumbledore asked me.

"Because there is water on the floor, footprints can be left clearly. Although the footprints are a little messy now, I have already recorded the original footprints." As I said, I waved my wand and the image of the third floor that once appeared appeared again. I continued: "In addition, the words on the wall are handwritten, and I have printed his fingerprints - this is the Muggle technique, but I think this is very useful. The rest is to check, because everyone's fingerprints are different, and the footprints can tell us whether the person is a man or a woman, and what is the approximate body shape."
