Hermione had gotten the Potion the next morning, and Evan mailed out the list of materials needed at noon.

That night, they gathered in the girls' bathroom on the third floor. Quietly, in the bathroom where there was no crying myrtle, Aven looked around and saw a small snake on the side of a copper faucet facing the cubicle.

"That faucet is broken, and it never comes out. ”

Hermione flipped the thick "Powerful Elixir" to the page of the compound potion, and checked the herbs that had just arrived against the recipe.

"It's the most complicated potion I've ever seen. She muttered, pointing her finger at the list of ingredients, "Lacewings, leeches, sapoo and ampus, as well as the horn of a powdered bicornus and the snakeskin fragments of an African tree snake." ”

"Oh my God, Aven, how much did it cost you to get these things, these materials aren't cheap!"

"Three hundred gold galleons, that's all the money the newspaper has made lately. Evan shrugged, "I originally planned to use the money to buy a Christmas gift for each staff member of the newspaper, and I thought of everything, but now I have replaced it all with these medicinal herbs." ”

"You say these things are worth three hundred gold galleons?!" Ron swallowed.

"That's right. Evan was also a little distressed.

"Well, we already have all the ingredients to make a polyjuice potion. In addition to these, there is also a little bit of something in the person who wants to change. ”

"I'm sorry. Ron said sharply, "What do you mean, what is a little bit of stuff in the man we want to be, if there's Crabbe's toenail in it, I'm not going to drink it!"

Hermione didn't seem to hear him, and continued, "We don't have to worry about that now, that little thing will be put in at last." ”

Ron turned to Harry speechlessly, and Harry's face was also not good.

"Now the question is, how long will it take to boil these potions?" asked Aven.

"Well, it takes twenty days at the earliest, which is the shortest boiling time for lacewings. ”

"Twenty days?!" Ron said, "it was Christmas, and I dare say Malfoy would hurry up and take down half of the Muggles in the school." ”

"And what do you have a good idea?" Hermione snapped her book and squinted at Ron.

"I think the house-elf who had been bothering Harry had a good idea, looking for a chance to get Malfoy up and let him go home and lie down until the end of the term. Seeing Hermione look at her angrily, Ron's voice grew quieter.

"No, we're not sure it was Malfoy who did it. Evan shook his head, "Besides, the materials have been bought, and we have no way back now." ”

"You're right, Aven!"

Seeing that Hermione was about to get angry, Ron hurriedly agreed, "It's shameful to waste gold gallons, but don't use your toenails, okay?"

Several people discussed it again, and after making sure that there was nothing missing, they began to prepare the materials separately according to the recipe.

Time passed, but the atmosphere in the school was still solemn.

After a Dark Defence class, Evan was left behind by Lockhart.

He has just been asked by Lockhart to play a Himalayan snowman who has a nose cold, and Lockhart has recently embarked on a new teaching activity in which he asks students to act out some dramatic scenes from his book.

"Aven, your performance just now is very good, that Himalayan snowman was scared away by me at that time, and I saved an entire village. ”

"Glad to be able to help you, Professor. ”

Evan asked uncertainly, "Is there anything else you need, the next class is Professor McGonagall's Transfiguration class, I'd better not be late." ”

"That's right. Lockhart gave his trademark smile, "Given the current tensions at the school, I'd like to start a dueling club." ”

"Dueling Club?!"

"Yes, you know that I have more experience in dealing with evil things than any other professor in the school. "It's not that I'm boasting, but I don't mind passing on these experiences to everyone to help you improve your combat effectiveness." ”

"Very good idea, what do you need me to do?"

"I'll put this on the bulletin board, you just have to help me spread the word in the newspaper, it's as simple as that. ”

Lockhart wanted to put the news on the front page, but not by name, saying it was to keep the mystery alive and surprise everyone when the time came. Evan smiled bitterly, he was really surprised.

What can Lockhart teach everyone, how to make bones nothing?!

However, after thinking that there was really nothing worth promoting recently, he readily agreed to the other party's request. Perhaps this is an opportunity to use the influence of the Dueling Club to salvage the newspaper's declining sales.

Not surprisingly, the news that the school will be hosting a dueling club has piqued the interest of the young wizards.

In the latest issue of the newspaper, Evan placed a big question mark, and listed the candidates who could be the teachers of the dueling club one by one, their strength evaluation, and their past records. After a lot of publicity beforehand, sales in this issue of Hogwarts Wizardry and Wizardry returned to their peak levels before the second attack.

Under Aven's deliberate guidance, most people thought that the teacher of the Dueling Club would be Professor Dumbledore.

It's simply shocking, considering that Professor Dumbledore hasn't used magic in public for many years since Voldemort's fall.

Needless to say, the excited young wizards, the many adult wizards who have subscribed to Hogwarts Wizards and wizards, and the parents of the students, want to be able to come to the school and have the opportunity to learn a trick and a half from the greatest white wizard of our time.

After learning of this news, Gu Fei Xinsheng, the editor-in-chief of the "Prophet Daily", also immediately wrote a letter, expressing his willingness to send someone to cover the opening of the dueling club.

However, it was rejected by the school, which made all the students more curious, and most of them thought that Professor Dumbledore's action was very likely.

Due to Aiwen's propaganda and guidance, the dueling club, which was originally planned to be held in a small area in the underground classroom, had to be located in the auditorium due to the large number of applicants.

At eight o'clock on Wednesday evening, the students hurried back to the auditorium after a short break in the common room after dinner. The long dining table vanished, and along one wall appeared a gilded stage, illuminated by hundreds of candles floating above.

Once again, the ceiling was dark like velvet, and the whole school came.

Knowing the truth of the matter, Evan was dragged from the library by Colin and Ginny, and in their words, it was hoped that Evan would guide them in defensive spells, and all first-year students knew that Evan was the best in his class.

Everyone was huddled together, each with their own wands in their hands, their faces full of excitement.

"When is the headmaster coming, and what do you think he will teach us?"

"Don't be stupid, Ron!"

Because of the chatter of the crowd around her, Hermione had to raise her voice and say loudly, "It can't be Professor Dumbledore, he hasn't done it in years." Besides, if it were him, there would be no need to be so mysterious, he himself would be the biggest gimmick. ”

"If it's not Dumbledore, who could it be?"

"I was told that Flitwick was a dueling champion when he was younger, and maybe he was the one who taught us. Hermione said uncertainly.

"Evan must know that he wrote that article?"

Harry and Ron hurriedly turned their heads to look at Aven, and nearby Colin, Ginny, and Neville looked at him expectantly.

"Don't look at me like that, I thought you would have understood it when you saw this kind of propaganda!"

"Wait a minute, what you said should be"

Harry's words turned into a moan, and Gilderoy Lockhart walked onto the stage, dressed in a fuchsia robe, shining brightly.

"That's right, it's him!" Evan covered his forehead weakly, "and Professor Lockhart seems to have brought a special guest tonight. ”

The lively atmosphere in the auditorium suddenly froze, and the original chatter disappeared completely, and everyone saw that it was no one else who appeared next to Lockhart.

It was Snape, who had a gloomy face, still wearing his usual black clothes.
