"Don't worry," Professor Lupine said calmly, because several students were frightened and took a few steps back. "There is a changeling over there." Most of the students were indeed worried that something would happen. Neville looked at Lupine in horror. Professor Ping glanced at him, and Seamus looked worriedly at the door that was still rattling. "Changelings like dark spaces," said Professor Lupin, "in wardrobes, in the spaces under the bed, in the kitchen cabinets under the sink - I've seen them in my grandfather's clock, which I only got yesterday. , I asked the principal if I could use it to give practical lessons to third-year students. "So, we first have to ask ourselves, what is a changeling?" Hermione raised her hand, "It can transform." Said, "It must become what it thinks will scare us the most." "Let me explain it more carefully," Professor Lupin said, and Hermione's eyes widened, "So, the changeling does not What specific shape? He still doesn't know what shape can scare the people on the other side of the door. No one knows what shape the changeling looks like when he is alone, but once he is released, he can immediately become "The shape that scares us the most." "That means," Professor Lupine said, deliberately ignoring Neville's panic, "we had a big advantage over the changelings before we started. Did you see that, Harry?" ?" Harry was about to answer this question with Hermione beside him, but Hermione was batting the ball at her feet, looking confused, but Harry wanted to give it a try. "Well - because there are too many of us, it doesn't know what shape is the scariest?" "Exactly," Professor Lupin said, and Hermione put down her hands, looking a little disappointed, "When you have to deal with a fantasy When looking for a monster, it's best to find a companion. He will get confused. What shape should he use? A headless corpse or a man-eating slug. I once saw a changeling make a big mistake. ¡ª¡ªHe wanted to scare two people into half slugs at the same time, but it was not scary at all. " "There is a very simple way to defeat the changeling monster, but it requires willpower. You know, the changeling monster is most afraid of. Just laugh, you have to try to think of some shapes that you think are funny. "Let's try it with the wand first, please follow me Redcross!" "Redcross!" Say it together. "Okay," said Professor Lupin, "Very well, but that is only an easy step. You all know that this sentence is not enough. And you are needed here, Neville." The wardrobe shook again, Although not as shaken as Neville, he was moving forward like hell. "By the way, Neville," Professor Lupine said, "First of all, please tell me what you are most afraid of." Neville's lips moved, but no sound came out. "Neville, I'm sorry, didn't you hear?" Professor Lupine said cheerfully. Neville looked around in fear, as if he was asking for help, and then said, almost as if he was talking to himself, "Professor Snape." Almost everyone laughed, even Neville smiled sheepishly. , However, Professor Lu Ping looked meaningful. "Professor Snape, hi Neville, I take it you live with your grandmother?" "Um - yes," Neville said nervously, "but I don't want Bugs to turn into her either "No, no, you misunderstood," Professor Lupine said with a smile, "I was wondering, could you tell everyone what kind of clothes your grandmother usually wears?" Neville looked very frightened. But he said, "Oh it's always the hat, a tall hat with a quill on it, and a long coat, usually cyan and sometimes fox fur. Scarf." "And a handbag?" Professor Luping reminded. "A red handbag," Neville said. "That's right," said Professor Lupin. "Can you think of the clothes? Neville, can you see the clothes in your mind?" "Yes," Neville said uncertainly, before Think about what will happen next. "When the changeling pops out of the wardrobe and sees you, Neville, it will turn into Professor Snape," said Lupine. "You just raise your wand - like this - and shout , 'Red Cross'. - And try to think of your grandmother's clothes, and if done right, Professor Snape would be forced into the quill-topped hat, the teal suit, the red handbag. ¡± A burst of laughter came, and the wardrobe swayed violently. "If Neville succeeds, the changelings are likely to turn their attention to us," Professor Lupine said. "I want you all to think about what is most likely to scare you, and then think about how to"To make it look funny" The room became quiet. "Is everything okay?" "Professor Lupine asked. Everyone nodded, and then rolled up their sleeves. Obviously, Lupine succeeded in raising everyone's expectations. He is a good teacher. At least, he is more suitable to be a teacher than Snape. "Neville , we are about to start," Professor Luping said, "get out of the way, okay? I'll ask the next person to follow. You guys should step back first. Okay, let Neville have space to prepare. "They all backed away and stood against the wall, leaving Neville alone facing the wardrobe. He was pale and frightened, but he had rolled up his sleeves and raised his wand. "Neville, I want to count to three," Lou said. Professor Ping pointed his wand at the handle of the closet, "One-two-three-come out!" Professor Lupin's wand end made a banging sound, and the wardrobe cracked open. Professor Snape with a crooked nose came out, his eyes scanning Neville. Neville took a step back , he raised his wand, opened his mouth and was speechless, Professor Snape approached him, reaching for his clothes "Ray-Ray-Redcross!" Neville shouted. There was a sound of whips being whipped, and Professor Snape stumbled. He was now wearing a long, strappy dress and a tall hat with a moth-eating stick on it. He had eagle feathers and a big red handbag hanging from his hand. "Hahahaha" Everyone laughed crazily. Neville paused in confusion, and Professor Lupine shouted, "Next, Parvati." Axi, who was behind, high-fived Patil, encouraging her. Then Parvati happily took a few steps forward, her face froze, Professor Snape turned towards her, and there was another bang. He turned into a mummy dripping with blood and wrapped in bandages. His vague butt turned to Parvati, and then approached her step by step, its hand raised, - "Redcross!" "Paviti said. A bandage caught the mummy's foot. It stumbled, faced forward, and rolled its head out. "Okay, very good! Next person! "Professor Lu Ping said.
