"Powerful Elixir?"

Mrs. Pince, the librarian, read it with suspicion.

"Yes, it was Professor Luo Cheng who asked us to come to the library to borrow this book, and he said that this book would help us."

Harry said nervously, the skinny female librarian was notoriously short-tempered, and Harry was very afraid of her after seeing her lecture a fat student who was "panting a little loudly" in the library.

"I warn you that forging the signatures of professors is a serious violation of the rules of the university, and you should not need this book for your age."

Mrs. Pince took the note directly from Harry's hand, then held it up and shone it into the light, as if to check whether it was a forgery, but in the end she didn't see the flaw, because it was really Professor Luo Cheng's handwriting.

"We don't know, but Professor Luo Cheng really told us that, maybe you can ask Professor Luo Cheng?"

"Hmph, it's none of my business, you wait for me for a while."

She strode past the tall bookshelves and returned a few minutes later. In his hand, he held a large, thick book that seemed to be moldy.

"Don't damage the book, this book belongs to the forbidden book zone, and it is very precious."

Mrs. Pince admonished.

Of course, Harry and Ron could only nod yes, and the two of them returned to the Gryffindor common room with their books, which was still bustling with activity, with everyone bragging about the Chamber of Secrets.

Harry opened the Potion of Power, and Ron leaned in and looked at the watermarked pages. They could see at a glance why the book belonged to the forbidden section. Some of the potions were so horrific that they were unimaginable, and there were some uncomfortable illustrations in the book: a man who seemed to have been turned inside out, and a witch with many arms sticking out of her head.

"Hell, why did Professor Luo Cheng say we need this book? The book is full of horrific and complex potions...... I don't think we can get help from this. ”

Harry said with a frown.

"He told us to ask Malfoy directly, and he told us to borrow the book after we said it was impossible, and I thought maybe there was a potion in it that would allow us to get the truth?"

Ron said, grabbing his red hair.

"So maybe it's this truth teller? The effect is extremely powerful, and just three drops can make you reveal the secrets of your heart...... Oh no, the ingredient list has been altered. ”

Harry flipped through the pages, and then saw the page labeled Polyjuice Potion, on which several people were changing into other people, but their expressions were extremely pained.

"Hey, what are you looking at!"

"Polyjuice decoction! Haha, I know this, it can make you a completely different person! Honestly, I'd love to turn into Percy and pee openly in the common room and make him a good shame! ”

The Weasley brothers didn't know when they came behind Harry and Ron, and their presence startled Harry and Ron.

"When did you get here?"

Ron was frightened by his twin brothers.

"Little Ronnie~ We've been behind you for a long time, it's just that you looked too seriously and didn't notice it."

George Weasley said, "Where did you get this book?" ”

He grabbed the book and looked at the cover, "Wow, it's really this one, "Powerful Potion", we can't borrow this forbidden book!" ”

Harry and Ron looked at each other, and had to tell the twin brothers what was going on. It's about the secret room, and the brothers with hippie smiles also know what is serious, after all, this time it also involves their only sister.

"I probably know what Professor Luo Cheng means, you can become a Slytherin student and ask Malfoy, he is probably bragging in the Slytherin common room right now, but unfortunately we can't hear it."

Fred said.

"Even if he doesn't tell the other Slytherins, then he certainly won't hide it from his two henchmen."

George added.

"Then let's make a polyjuice decoction! Go ask Malfoy directly. ”

The two said in unison.

"But, can we make such a complicated potion?"

Harry was confused.

"Don't worry, I'm Fred/George, a once-in-a-century potions genius!"
