"It's a truth spit, colorless, smelly, tasteless, and the person who drinks it will tell the truth irrepressibly. The main material for the preparation of this agent is the sap of the rhizome of the windward stone eggplant, which is acidified and ......"

"Oh, Miss Granger, that's the recipe and the preparation process." Slughorn hurriedly stopped Hermione from saying, "Very well, that's the right answer...... So, the next crucible ......"

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

"Well, please say-"

"There's a polyjuice potion in this cauldron," Hermione said immediately, "it's complicated to make, and it takes ...... Oh, sorry, Professor! I mean, it allows the drinker to change their appearance, including physiognomy, body shape, skin features, etc., turning the drinker into a different person - the recipe is characterized by a little bit of tissue on the subject's body, and the whole preparation process often takes a month. ”

"Well, yes yes, excellent answer!" Slughorn couldn't help but applaud, "Miss Granger, I even have reason to believe that you might be able to make it yourself......"

Of course, the old man didn't know, in fact, Hermione had already made a pot of her own, and it was only when she was in her second year.

“…… That being the case, Miss Granger. Slughorn shrugged his shoulders and said, "And this pot?" ”

"Uh...... Well. ”

As the old man pointed to the third cauldron, Hermione hesitated unusually. Inside the silver crucible was a colorful and looming liquid that seemed to be a calm liquid at first glance, but it was as if it could be seen directly at the bottom of the crucible.

Of course, she didn't know this potion anymore, on the contrary, among the four crucibles, only this one was the one she was very familiar with.

“…… This is the Immortal Elixir, an invisible potion created by Professor McLean, that allows the drinker to hide himself completely from others from noticing his presence. Its main material is the wings of fairies. ”

At this point, Hermione paused for a moment before continuing in confusion.

"In addition," she said, "the potion was certified by the Potions Administration of the International Confederation of Wizards in early 1992, and its name was published in the international academic journal Practical Potions Master, and it received the annual Silver Award that year." But ......"

"Aha! Miss Granger, I know you have any questions," Slughorn said with a smile, "That's right, according to the Wizards' Federation, the recipe for the Immortal Elixir must not be released until after Professor McLean has passed away!" But—"

As he spoke, he suddenly raised an index finger and said excitedly, "If it is the transmission ordered by Professor McLean himself, it is not within its limits. Yes, that is, now only those in our classroom in the whole world can learn how to prepare this potion! ”

The broom may be able to get more and longer-term benefits, but as far as today's maca is concerned, it's just that the immortal hidden elixir is not so precious. In fact, he already has a lot of original or improved potion recipes in his hands, although none of those potions have been sent to the Wizards' Federation for verification, but they have long been sold in the black market.

Snape had mentioned in his first Potions class that potions could "accumulate wealth, increase prestige, brew glory, and prevent death." The first step of Maca can be said to be preliminarily achieved, so it is naturally the second and third steps that he will proceed to.

And this also happens to complement his current state, so why wouldn't he do it?

At the moment, Maca is undoubtedly the hot topic in the whole of Hogwarts, and when Slughorn said this, the students who heard that they could learn the Immortal Elixir applauded excitedly. Almost all the students in the Potions class are very interested in Potions, and how lucky they are to learn a potion that no one else knows.

"Alright, alright!" Slughorn waved his hand and motioned for everyone to calm down, "Miss Granger, your answer to this Immortal Elixir is just as accurate, it's really good!" That...... What about this last one? ”

As he spoke, the old man stretched out his hand and pointed to the remaining gold cauldron. The pupils, attracted by the aroma coming from the cauldron, looked at it again and their throats stirred.

"This ...... Well, it's an aphrodisiac. Hermione couldn't help but swallow her saliva, her mouth a little dry, "Its potion has a unique mother-of-pearl color, and the steam rises in a double spiral when it boils...... It can cause an extremely strong sense of obsession or obsession in the drinker. Similar to a polyjuice decoction, it also requires tissue from the human body to be truly effective. ”

"That's right!" Slughorn nodded, a sincere admiration on his face, "Of course, a little ...... Well, Miss Granger, is there anything else you'd like to add? ”

He seemed to be about to say something, but after a moment's hesitation, he asked Hermione first.

"Hmm......" Hermione blinked, "and when it comes to smelling of it, everyone smells differently, depending on who they like...... For example, I smell something like a scroll, ink, the rhizome of a certain plant, and ......"

After listing several scents, she suddenly pursed her lips and said no more.

"Good, good—" Slughorn digressed rather empathetically, "it's part of the aphrodisiac, though...... I'd like to add one more thing! The effects of aphrodisiacs don't just apply to humans – not even living things. Be aware that according to the latest research, even if you end up throwing a stinky sock into the solution, it will still complete the process and make the user obsessed with the ridiculously stinky sock! ”

"So, how do you say that?" The old man shook his head and said, "As Miss Granger just mentioned, the effect of aphrodisiacs is obsession or infatuation, not true love!" This obsession is terrible, it is very dangerous, please don't underestimate it......"

“…… Alright, now," Slughorn swept all four cauldrons away with a wave of his wand, "The easiest potion of the lesson begins—that's too early for you!" Oh, except for the Immortal Hidden Elixir......"

"Why?" A Ravenclaw student suddenly asked.

"Because most of the steps are not complicated," Hermione said casually, "except for the first step of the second phase, which involved a very novel theory, which was developed by both Professors McLean and Snape. ”

……

As Hermione had said to Harry at the beginning, the course was indeed much harder than what had been done in the past. Not to mention the four potions that Slughorn showed everyone at the beginning, even what the old man called "the simplest kind of potion" made the students feel great resistance to learning.

So in the potions class the next day, the bald old man came up with a good idea to greatly increase everyone's desire to learn.

“…… I'm sure you've all seen it," Slughorn pointed to the smallest black cauldron on the lectern, "maybe Miss Granger can explain the name and effect of this potion as well?" ”

As he spoke, the liquid in the small cauldron pulsed lightly, looking like flowing gold. Although the amount of it is very small, anyone who looks at it will feel extremely satisfied.

"That's the Elixir!" Hermione didn't even look closer, she just stood on the side of the small round table on her side and replied, "Some people call it the 'Luck Potion', and the effect is to bring good luck to the drinker throughout the day!" ”

"Couldn't be more right!" Slughorn smiled with satisfaction, "Yes, it was only necessary to say this to introduce it - 'good luck all day'!" Just take it and you'll find that whatever you do will go very smoothly – sometimes it's like a miracle! ”

As he spoke, he paused, but then solemnly admonished, "However, the preparation process is quite complicated, and the slightest mistake can have terrible consequences. And, please note that it is toxic and should not be taken in excess; Moreover, its good fortune seems to come from 'overdraft', and when the effect of the medicine wears off, bad luck will follow......"

"Bad luck?"

Harry was clearly intrigued by the thing, and when he heard Slughorn mention the side effects, he immediately pressed after it.

"That's right, bad luck!" Slughorn repeated, "In fact, we still haven't reached an accurate conclusion on this subject. Sometimes it starts to appear after the effect has passed, and sometimes it occurs at intervals of an indefinite period of time...... It may even affect the people around the user, maybe it's a child! This side effect was actually raised by your Professor McLean when I discussed it......"

"Have you taken it?" Harry asked, "I mean, have you ever experienced that so-called 'bad luck'?" ”

"Oh yes...... I've tried it twice," Slughorn said, "and of course, luck can't be measured, can it?" I remember the second time when I was fifty-seven years old, and on the third day after taking it, I fell and broke my head...... I don't know if that counts? ”

"All in all," he said, waving his hand, "the most important thing you need to remember is 'no overdose,' and you can't be wrong about that!" As for the occasional moderate dose, that's fine...... So far, at least, I haven't heard of anyone having problems taking the Elixir! ”

"So what!" Finally, Slughorn touched the cauldron and said with a smile, "A magic potion will be the prize for the first person to brew the 'Living Hell Potion'!" ”
