In the middle of the night, Ning An listened to the loud snoring of Crabbe and Goyle on the bed next to him, and felt that several people were almost asleep, so he silently recited a few incantations and slowly lifted the quilt.

He didn't take off his clothes, he was still wearing a black robe, Ning An waited for a while, the mark on his arm didn't react, so he tiptoed out of bed, gently put on his shoes, pushed open the bedroom door, and went up to the Slytherin lounge.

In the lounge, two figures also dressed in black robes, standing in front of the fireplace, were Daphne and Caridora.

"Ah, Ning'an, here we are......" Daphne said in a suppressed voice

Ning An made a clear gesture, and then motioned for the two of them to come closer to him, and the three of them gathered in a small corner of the lounge

"We need to be especially careful of Filch and his Lady Loris, as well as the pesky Peeves, so that the three of them don't find out, don't rummage through the books in the forbidden section, we only look for books about Dementorship spells."

Daphne and Calydora both nodded, and Ning An waited for a while, seeing that no one in the bedroom was following her, so the three of them lined up and walked out through the damp stone door.

Hogwarts looked a little scary late at night, the underground where the Slytherin lounge was located, perhaps because of its proximity to the Black Lagoon, was always wet, and although torches were lit on both sides of the corridor, the sound of "tick, tick" falling water at the top still made people feel cold and gloomy.

The three of them lined up, Ning An walked in the front, Daphne tugged at the corner of Ning An's clothes, and Caridora tugged at the corners of Daphne's clothes, walking slowly and cautiously.

Filch's office was also on the basement floor, which made the three of them have to be more careful, Ning An felt that Filch would most likely patrol the castle, but he didn't dare to be careless, he still slowed down his pace, passed the office with the utmost care, and several people finally came to the auditorium on the first floor.

"To be honest, it's a great feeling to sneak out at night!" Daphne exclaimed, whispering behind Ning An, she enjoyed such an adventurous action.

"Don't speak, Daphne." Calidora also controlled the tone of her voice, reminding Daphne with rare caution.

"Alright, girls, be quiet...... Ning An led the way, he found that the Slytherin common room was a bit remote, and they had to climb many flights of stairs to get to the library.

The stairs of Hogwarts did not rest even in the middle of the night, they moved all the time, but fortunately, Ning An had memorized the route of the month, and most of the portraits hanging on the walls that worried him were also asleep.

There is an oil painting of many women wearing skirts with liners, one of whom is not sleeping, and after seeing the three of Ning An, she has a "I understand" expression on her face, and jokes with them

"Yo yo, look, look, you little adventurers who act at night~ Heha, I've seen a lot."

Ning An didn't pay attention to her, and led the other two people all the way through quickly, but fortunately, they were lucky, they heard Filch's footsteps several times in advance, and they all bypassed in advance, and finally came to the library safe and sound.

At night, the library adds a bit of an eerie atmosphere, with rows of tall bookshelves towering, like man-eating monsters.

"Hurry up, Daphne, the forbidden book section is in the back." Ning An gently tugged the stunned Daphne, "We don't have much time. ”

The three of them came to the forbidden book area. The atmosphere here is even more eerie than before, with large thick books on the shelves, and the faded gilded bronzing text on the books seems to indicate their long origins.

Ning An took out his wand from his bosom and whispered, "Fluorescent flickering." Then, the wand head lit up with a white faint light, Daphne and Calidora also took out their wands and cast a light charm, and Ning An applied a levitation charm to the three wands, so they searched for it under the white light emitted by the three wands floating on their shoulders.

The forbidden area of the library was a strange place, and the three of Ning An seemed to be able to hear these books, discussing something in a low voice, and the sound of rustling came from the bookshelves, somewhere in the empty room, and behind them from time to time.

Daphne tugged at Ning An's clothes, and this girl, who was not afraid of heaven and earth, actually said with a trembling voice, "Ning...... Ning An, how do I feel something...... Watching us. ”

"It's really weird here." Ning An looked around and said, "So let's quickly find the book we are looking for and leave here." As he spoke, he looked at Calydora, who was following Daphne and did not speak, but her face was also unpleasant, and whispered

"Let's look for the three of us separately, remember to notify each other with a snake mark when we find it." He patted his arm as he spoke.

Daphne nodded stiffly, then hesitantly moved to the bookshelf to the left, and Caridora didn't say anything more, but gently touched the bookshelf to the right.

Ning An turned around and looked at the books on the shelves that were heavy and simple, some of them were covered with dust and even stained with blood, and slowly looked for them.

"Hmm...... 'The Curse of Barbots...... It's not this...... Neanderthal Witchcraft Chronicles isn't ......" Ning An quickly skimmed through the title, hoping to find a book that matched the spell he was looking for.

"Huh? This is ......" After a while, he accidentally found such a book, the dark blue cover, compared to the other books stored, it was not very conspicuous, but Ning An was attracted by the title of the book - "The Aurors Commonly Used Magic Manual". He remembered that there was a spell that could make people invisible, the "Illusion Charm", which was the Auror's special magic.

Without saying a word, he pulled out the book and hid it in his arms, and continued to search, but the next moment, he felt a tingling in his arm, and it seemed that Daphne and the others had gained something.

Without further hesitation, Ning An moved closer to the faint white light on his left, and Calidora, who was on his right, also walked towards him.

"Hey, hey, Ning'an." Daphne happily whispered to Ning An, "Look what I found?" ”

"Be quiet, Daphne, you don't want to lure Lady Loris here." Ning An reminded, and at the same time leaned over, and through the white light shed by his wand, he saw a thick book with a black cover in Daphne's hand, which read "Control the Enemy - Precision Control Magic".

"There's a show!" Ning An shouted excitedly, and it happened that Calidora also came behind him, and seeing that the two seemed to have found the book they were looking for, they also whispered

"It's time to go, we've been doing it for a long time."

"Oh, not yet, we'll have to wait." Ning An said as he took out two rolls of parchment paper from his bosom, and three quills, which he had prepared a long time ago.

"What is this for......? You don't want us to copy books, do you? Daphne showed a surprised expression, and when she saw Ning An nodding at him, she shouted a little impatiently, "It's too late, we won't be able to finish a book until dawn!" ”

"Don't worry, we don't have to copy the whole book, we just need two spells." He spread out the two rolls of parchment on the floor, then handed them the quills and said:

"Irma? Pence checks the number of books in the forbidden section every day, we can't take these books out, come on, Daphne, Carly, look for the "Dementor" spell in this book, I think there's a good chance it'll be here. ”

After speaking, he didn't look at the two of them, time was pressing, Ning An lay on the ground and pressed the parchment with his elbows, while quickly opening the big book with a blue cover.

"Phantom Body Spell, Phantom Body Spell ......" Ning An kept muttering in his mouth, because the voice was too small, it sounded like the sound of a mouse eating something.

"There it is!" He let out a low shout.

"Please, be quiet." Calidora turned around and complained, her nerves strained now.

Ning An hurriedly raised his hand and made a "understand" gesture, then looked impatiently at the book, only to see that it was written

"Phantom Spell, Auror Spell, Practicality☆☆☆☆, Difficulty☆☆☆☆."

He hurriedly rummaged down for the method of casting the spell, but he had no time to look closely, so he could only copy lines of text on the parchment as fast as he could.

In the empty and dark library, there was a rustling sound of writing, as if there were still students here in the middle of the night desperately rushing to catch up with their homework, Ning An felt that his hands and neck were about to break, but he didn't dare to stop, he always felt that the few of them had taken too long.

Sure enough, the next moment, while he still had the last bit left to copy, there was a sound of footsteps in the library, and Filch's low, frightened cry "Who's there!" ”

"Shhh Daphne suddenly raised her head and looked at Ning An, as if to say, we haven't finished copying yet, what should we do next, and Calidora didn't raise her head, she was already at full speed, writing quickly.

Ning An listened to the footsteps getting closer and closer, and no longer hesitated, gently handed the blue book to Daphne, motioned him to continue copying, and at the same time gently grabbed the wand, extinguished the light on the front of his wand, quietly lurked next to the bookshelf, and poked his head out.

Not far away, I saw a hazy figure in a coat, carrying a lantern that emitted a dim yellow light, step by step, cautiously walking towards Ning An'an.

Ning An only felt that the palms of his wand were soaked with sweat, and since Daphne and Caridora were still using fluorescent flickers, there was no doubt that Filch would find the light here if he walked further.

Sure enough, Filch seemed to see a faint light shining through the bookshelf at this time, and he could see that his body suddenly tightened, and he lifted the lantern, as if he wanted to illuminate a few meters ahead, and his voice shouted with a little trembling, "Who is it!" …… Who's there! ”

Ning An finally saw Filch's figure clearly, and he took advantage of the moment when Filch hadn't noticed him yet, stretched out his wand a little, and whispered in his mouth:

"Fainted"

Then, a flash of white light flew out and hit Filch with a "pop", and with a "bang", the lantern fell to the marble floor of the library, and Filch fainted to the ground.

"Okay, Ning An, we've copied it!" Daphne also happened to finish copying the spell at this time.

"Quick, hurry, put the book back and let's go." The trio hurriedly put the book back in place, straddled Filch's body to the ground, and ran towards the Slytherin common room at three times the speed they had come.
