Powerful aphrodisiac, the world's most effective love potion.

When it is introduced, it is usually noted that this potion is extremely dangerous!

Powerful aphrodisiacs can make people fall in love, but that is not real love, but mental deception.

It's like the Imperius Curse, which can control a person, make people fall in love with each other inexorably, can't control their emotions and bodies, and is willing to do anything for them, including giving their lives.

In a sense, it's even scarier than the Imperius Curse.

Voldemort's mother once used an aphrodisiac to make the elder Riddle fall in love with him, and finally gave birth to Voldemort.

There have been many more such things in history, and there have been dark wizards who have used this method to make Muggle kings fall in love with a woman or themselves, and thus indirectly control the entire country, taking advantage of the opportunity to complete their evil intentions.

Evan had no idea of using an aphrodisiac, but he didn't deny that the smell was still pleasant.

You can prepare a bottle to take on your body, and take it out and smell it in the dead of night and when you are lonely and lonely, the effect is very good......

Don't get me wrong, because another property of aphrodisiacs is that different people will smell differently.

According to the most liked, needed, and beautiful things in everyone's heart, that is, the taste of love.

Aven had just smelled the peculiar scent of Hermione's body inside, well, maybe it was the smell of shampoo, anyway, it was very reassuring, and the smell of his favorite floral scent made his body react strangely.

"Alright, alright, alright!" Slughorn said, walking over to the podium.

Looking through the many hot vapors, his large figure seemed fluttering.

"Students, please take out the scales, medicine bags, and, don't forget to take out your "Advanced Potions Making" textbook, let's start this semester's potions class......"

"Sir?" said Harry, holding up his hand.

"What's wrong, Harry?" Slughorn asked gently.

"I don't have books, I don't have scales, I don't have anything, and neither does Ron. Because, we didn't expect to be able to go to the advanced class, so we ......"

"Ah, by the way, Professor McGonagall mentioned this, don't worry, kid, don't worry at all. You can use the ingredients in the locker today, and the scales can be lent to you, and there are some old textbooks here, which you can use first, and then you can write to the Blotts......"

After making sure they weren't in Potions class, Harry and Ron didn't pack the things into their salutes.

Aven had spare scales, crucibles, and materials, but he didn't bring them out.

He thought it was an opportunity to see if Harry could find the old Snape textbook.

He remembered a textbook that contained improvements to Snape's potion recipes and brewing processes described in Advanced Potions Making, as well as some of Snape's own magic.

To be honest, Evan was very interested in the textbook and the content on it.

At the very least, it will help a lot with potions.

When he visited Snape's locker before, Evan also made a point to look for it, but found nothing.

Snape didn't seem to take the textbook out, but put it somewhere.

This semester, he gave up the classroom to Slughorn, and he may have left it behind when he was packing up, or Slughorn found the textbook elsewhere while tidying up the classroom.

Anything could have been, in short, it takes luck to want this textbook, and Evan doesn't have that luck.

So, he was going to let Harry try it......

Slughorn strode over to a storage cabinet in the corner, fumbled around for a moment, and then pulled out two tattered copies of Liberasius Polage's Advanced Potions Making, along with two sets of faded scales, and handed them to Harry and Ron.

Is that the one? Aven stared at Advanced Potions Making in Harry's hand.

"Show me, Harry. He whispered, taking the tattered textbook.

The pages were moldy, scribbled all over them, and the margins of each page were as black as the places where the potions were printed.

I guess that's it, right? There's no way to confirm that.

He flipped the page of the book to a potion, carefully identifying the recipe on it.

"Alright!" said Slughorn as he returned to the front of the classroom, his already bulging chest pushed forward again, and the buttons on his vest looked like they were about to burst, "I've got a couple of potions to open your eyes, just out of interest, of course. By the time you've completed the Advanced Class, you'll be able to make something like this. You haven't done it yourself, but you've certainly heard of it, and who can tell me what this one is?"

He pointed to the crucible closest to the Slytherin table, where only the water was tumbling.

This obviously won't be clear water, then it can only be ......

Hermione's well-trained hand was raised first, and Slughorn pointed at her.

"It's the truth elixir, a colorless, tasteless elixir that forces the person who drinks it to tell the truth. Hermione said.

"Very good, very good! It's the Truth Elixir, it's really remarkable to be recognizable, now ......," Slughorn said happily, pointing to the crucible closest to the Ravenclaw table, "It's more famous, and it's been highlighted in a few pamphlets that have been distributed in the ministry lately, who can?"

Before he could finish speaking, Hermione's hand was raised again.

"It's a polyjuice decoction, sir. She said.

The second crucible was a slowly bubbling muddy thing that they had made when they infiltrated the Slytherin common room, and it was all the more familiar to Hermione, who had helped Evan make it many times since then!

"Great, great! And this ...... here. What do you say, dear?" said Slughorn.

He looked a little surprised to see Hermione's hand raised again.

"It's a powerful aphrodisiac!"

"Not bad at all, no need to ask. Slughorn showed genuine admiration at this point, and said, "I think you must know what it's for?"

"It's the most potent love potion in the world!" Hermione said.

"Exactly! I think you recognize it by its peculiar mother-of-pearl sheen, right?"

"And its characteristic spiraling pink vapor, which is unique among all potions. Hermione said with interest, "And it smells different from person to person, depending on what they like best." I could smell freshly mowed grass, brand new parchment, and ......"

She blushed suddenly, and said no more, just sneakily glanced at Evan beside her.

Unfortunately, Evan didn't hear this, and he was concentrating on the dirty textbook.

Otherwise, he should have guessed that Hermione might be trying to say what his saliva tasted like......

Or rather, it's the feeling of being obsessed with kissing.
