At two o'clock in the afternoon, Harry Potter and Ron arrived in the Potions classroom in the basement before class.

In the hallway in front of the classroom, Harry saw Zhang Xu chatting with several students from Eagle Academy.

Harry was about to go up and talk to him when the classroom door opened, and Slughorn came out and welcomed the students into the classroom. It's just that Harry doesn't like Slughorn's overzealous appearance towards him, and always feels that he has something to do with him.

When the students walked into the classroom, they found that it was filled with a strange smell of water vapor, and everyone looked curiously at the row of steaming cauldrons in the classroom.

Harry felt that it was the first time he had smelled such an alluring scent, and his mind was conjured up with his favorite self-heating hot pot, his favorite broomstick, and the time he had snuck out of the Burrow with Ginny on a summer night.

The next moment, Harry's tiger body shook, and the whole person immediately came back to his senses. He had sensed that the smell was not simple, and if the Dementors could bring to mind the sights he feared most, the strange smell in the classroom now was the opposite, reminding him of his favorite things.

(*❦ω❦) (❁´ω`❁) (๑╯︶╰๑)

Harry looked around and saw that the students in the classroom all had satisfied expressions on their faces.

Harry was relieved when he noticed that the smell was coming from one of the cauldrons in the classroom, and since Professor Slughorn had refined it and placed it in the classroom, it meant that it was harmless.

At this moment, Slughorn asked everyone to focus on him, and then asked everyone to take out the textbooks and balance classroom utensils.

It was then that Harry remembered that neither he nor Ron had textbooks or other utensils.

After raising the issue with Slughorn, Harry and Ron were given the old textbook and the old scale.

Then the course officially began.

Slughorn spoke to the students with his bulging belly, "I asked Professor Snape about your course. I have to say that the development of the potions class in the past few years has been too fast, and the new equipment and new methods have greatly improved the refining power of potions. ”

"It's just that it takes too long to make potions that we're about to learn, so I think that the preparation steps such as the determination of the active ingredients of the materials can be done well in advance of the class. This step will be given to the younger students to complete in their spare time, so that they will have more opportunities to get in touch with this wonderful world. ”

"So, let's follow the old method in the book for today's potion refining first, and the next class will begin, let's get ready, and then we will explore the new world together."

Slughorn's words didn't cause much reaction from the students, after all, each professor has his own style, and if they change their style rashly, they may cause the old driver to overturn.

With that done, Slughorn walked over to the row of cauldrons and said, "I've prepared several potions for you to open your eyes to. Can anyone tell me the names of these potions? ”

Zhang Xu, who was addicted to the taro button meat, sweet and sour tenderloin, braised lion head and Buddha jumping over the wall brought by the aphrodisiac, slowed down and let Hermione, who was sitting at the table next to him, win the first kill of the class.

Then came Hermione's showtime, and she perfectly answered the names and characteristics of the elixir, polyjuice potion, and aphrodisiac.

What followed was a wave of business blows between Slughorn and Hermione, and Hermione ended up earning twenty points.

Next, Slughorn looked at Zhang Xu, who had been a little slower just now, and said to him, "Can you tell me what you think of them, Mr. Zhang?" ”

Zhang Xu was slightly surprised, he didn't expect Slughorn to give himself points on this issue.

Zhang Xu stood up and sorted out his thoughts for a moment before saying, "I think the effects of the Truth Elixir and the Aphrodisiac are the same as those of the Imperi Curse. ”

As soon as Zhang Xu's words fell, the students in the classroom were in an uproar, they didn't expect that these two potions could be related to the Unforgivable Curse.

Slughorn only nodded slightly, waiting for Zhang Xu to continue.

Zhang Xu continued: "The Imperius Curse can make people's minds go blank, make people indulge in false happiness and joy, and then there is a voice in people to accomplish something. ”

"And the effect of the elixir and the aphrodisiac is similar."

"Truth-spitting will imply that people are telling the truth."

"Aphrodisiacs suggest that people themselves will fall in love with certain people."

"That's the right answer." "You can't appreciate it until you've experienced them." ”

Zhang Xu didn't take this stubble, but continued: "The compound decoction is related to human transfiguration, and its effect is like human transfiguration that applies a specific effect to people. If used incorrectly, it can also transform a person into a person with the characteristics of other animals, such as a cat person. ”

In the next second, Zhang Xu was attacked by someone's sight.

After talking about these three potions, Zhang Xu followed Slughorn's routine and said, "If I'm not mistaken, the golden potion in that little black cauldron should be a blessing elixir, right?" ”

"Ho-ho," Slughorn laughed twice with his characteristic laugh, and then said to Zhang Xu, "That's right, Mr. Zhang. You should know what it does. ”

"It's a lucky medicine that brings good luck." Zhang Xu replied, but there was some disapproval in his tone.

Zhang Xu, who had obtained a little elixir from other sources, tried its effect.

The most intuitive effect of the elixir is to improve the human body's various senses, improve the ability to think and calculate, dig deep into memory and improve intuition.

After drinking it, the overclocking and high-speed brain can make the right choice.

But for ten consecutive draws, two-color balls and the like, Zhang's personal test conclusion is useless.

And Zhang Xu really wanted to study the elixir and see if he could make a "Murphy Elixir" with diametrically opposite effects.

Slughorn was satisfied with Zhang Xu's answer, and after letting Zhang Xu sit down, he explained the advantages of the elixir, the scope of its prohibited use, and the consequences of its abuse.

After adding thirty points to Zhang Xu, Slughorn continued to lecture.

Next, Slughorn announced that he would be taking out a vial of Elixir as a prize for today's lesson.

For a while, the students in the classroom suddenly became excited, and they were eager to try it, intending to win this bottle of elixir.

But Zhang Xu is not interested in this.

There is still a pot of elixir on the other side of the classroom, if Zhang Xu wants it, he can take the gold coin to Professor Slughorn, "Professor, how much is the elixir a pound?" Bring me two pounds! ”
