As we enter November, it gets very cold at Hogwarts. The surrounding peaks were covered with a thick layer of snow, and even the surface of the lake was frozen thick and hard. The students all changed into winter clothes, put on gloves and scarves.

Restaurant, breakfast time

"How's the preparations? Harry," Ivey asked, eating the pie

Harry kept staring at the book in his hand, not even bothering to eat.

"It's okay," he looked up, revealing two large dark circles under his eyes

Although his face was slightly tired, his expression was very excited

"I was still a little nervous, thanks to Hermione!" He showed the book in his hand

"She found this for me – The Magic of Quidditch. This book is so much fun! He flipped through the pages

"Did you know that there are more than seven hundred fouls in Quidditch. Among them......"

"Alright, Harry, you don't have to give us science, you just know for yourself." Ivey waved his hand hurriedly, he had no interest in Quidditch.

Ron listened with relish

"Harry, it's going to be tomorrow, you'd better rest a little bit more today," Hermione suggested

"Don't worry about it, Hermione. If you really want to help Harry, lend us your homework to copy. Ron nodded at her

"Hehe-I can only help you correct your mistakes, don't even think about copying homework. You should learn from Ivey, you do your homework. Right? She confirmed

"Of course! I'm not like them, I've never copied Betty's homework! Only what you have learned by yourself can be called knowledge. Ivey said that he was determined to draw a line with the two of them

Betty didn't debunk him either

"It's almost-hiccup~" Ivey patted his stomach, "Are you full?" Betty nodded

"Then you eat slowly, Betty and I will go to the library," Ivy got up to leave

"Library? What are you going to do? Need my help? Hermione asked enthusiastically

"Well—it's hard to say, just see. I won't be polite if needed."

————

The two of them went to the library on the second floor of the castle, where there were hundreds of bookshelves. There are a lot of books on it, and most of the books can be read by students. But the forbidden area requires the approval of the professor to read it. Of course, you can also peek at it yourself.

The last time Ivey was here, it was to find cooking magic.

"Betty, you're out there to help me find it, I'll go around the forbidden book area"

"Be careful not to get caught by Mrs. Pince"

"Don't worry, they know I can't use spells, even if I find out."

The forbidden book area is in a separate room. Ivy didn't go through the main door, he ran to a glass window and pulled out his wand

"Alajo Cave Open"

On the inside of the glass window, the latch that locks opens.

Ivy was excited, it was the only spell he had mastered since he entered the school.

Turning over and entering, the restricted area is not as brightly lit as the public area, there are few candles here. Most of the books on the shelves are pitch black and green, and the book covers are smooth and delicate to the touch, just like human skin. At first glance, it is not a serious book.

Ivy flipped through one book after another: "The Dark Book", "Werewolves and Vampires", "Curse of Mass Killing", "Death Eaters Keep the Word", "The New Unforgivable Curse - Corrupting Curse", ......

Countless books whose names alone would have scared the scare of Neville have been flipped. But I still didn't find what I was looking for

A few more bookshelves. Just when Ivey had given up and was just a mechanical spot check, his gaze suddenly froze. A dark red cover caught his eye, and on the spine of the book were a few large gilded letters: On the Twelve Uses of Dragon's Blood.

"It seems like the twelve uses that Dumbledore discovered," Ivy became interested and began to flip through it.

"Anti-beauty potion, destruction potion, poisoning potion········ Bone quenching potion - yes! ”

Ivey's eyes lit up, and he continued to look

Bone Quenching Elixir: Discovered by Albus Dumbledore in 1956, the seventh use of dragon's blood. It can greatly increase the upper limit of human physical fitness, and even have the strength of a troll, which is a very great discovery. Unfortunately, the sorcerers revered wisdom, truth, and knowledge, and they boasted of their grace and despised rude fights and savage physical confrontations. Therefore, the bone quenching agent has not received widespread attention, and few people know the specific production method and use method of it.

When he came out, Betty was sitting at her desk rummaging through it, which was already stacked thickly. Wrap your arms around her from behind, chin resting on her shoulders

"How's it going, did you find anything?"

"I found a few spells that had a similar effect, but they didn't cure the symptoms, and the effect would disappear once the spell time passed." Betty leaned back and said lazily

"Thank you, mua-" kissed her

"Seeing how happy you are, you've found a way in the restricted area?" Betty looked back at him

"I can only say that I have found the goal, but there is no specific method." At the mention of this, Ivy was a little annoyed

"How?"

...... Ivy briefly introduced the bone quenching potion

"That's it~" Betty thought for a moment, "Why don't you ask your cousin?"

"Can she know?" Ivey wasn't convinced

"Cousin Erin is the chief pharmacist of St. Mungo's Hospital for Magical Injuries and Injuries, and belongs to one of the few potions masters in the wizarding world."

"She's so awesome?" Erin's unobtrusive appearance makes it hard to convince, "Then write a letter and let the round cake be brought to her?" ”

"No, when the Quidditch match is over, it's Christmas. We went back and asked directly."

"It's okay, let's wait for the Christmas holidays"

The two slowly walked out of the library

————

In the evening, in the auditorium

By the time Ivey and Betty arrived, the hall was already full.

"Ivey, Betty! Come on" sharp-eyed Ron, see them at once.

"What's wrong with you?" As soon as he sat down, he saw Harry with a serious face

"I found something terrible," said Harry, "remember what I told you earlier, that room guarded by the Three-Headed Hellhounds?" ”

"Well, remember"

"I suspect Snape is trying to steal what's inside"

It turns out that the plot has come to this, and there is a moment of silence for Snape in my heart

"How can there be such a conclusion? As you said, the contents of that room were the same things Hagrid had taken from Gringotts, and there was a dark wizard who broke in and tried to grab them. Then you mean, Snape is the dark wizard. But if he were a dark wizard, do you think Dumbledore would let him teach at Hogwarts? ”

"It doesn't have to be Gringotts himself, it's probably his accomplices," Harry still thought Snape was suspicious

"Harry, do you think Gringotts is a bank? Grab it if you want! It would take a very powerful dark wizard. After the fall of the Mysterio, most of the dark wizards entered Azkaban. Those who remained outside either changed their ways, or went into hiding. It is unlikely that such a strong accomplice will be found," Ivy tried to correct his thoughts

"But Gringotts is a bank~" Ron was puzzled

"Shut up!" Hermione glared at him

She agrees with Ivey: "That's right! I know Snape isn't friendly, but he would never steal something that Dumbledore kept in his keep. ”

"Hermione, you always think that all teachers are saints. I agree with Harry! Ron also had his opinion

"Of course I'm not going to jump to conclusions for nothing," Harry said, organising the language

"You probably didn't notice the time we fought the trolls on Halloween, but I noticed that Snape had scratches on his right leg. And when we rushed to save Hermione, Ron said the same and saw Snape flash around the corner. Right? ”

Several people looked at Ron

"I did see him," Ron affirmed

"That's right! I had just gone to the staff break room and saw Filch bandaging his wounds. Filch said viciously, 'How can you keep an eye on three heads at once?' but I was found out and ran out for a random reason. ”
