It is different from the relaxed and curious atmosphere when the young wizards answered the questions.

As Elena began to speak, the underground classroom suddenly became silent, as if the professor was lecturing, and every bubbling and boiling sound of the surrounding potions seemed to be amplified tenfold.

Perhaps because of her more than a year as a teaching assistant in Potions classes, Elena unconsciously took on some of Snape's usual style when it came to Potions lectures—a slightly muffled voice, but enough for everyone to hear.

"Needless to say, the Elixir is an extremely peculiar potion because it can bring good luck. ”

With Slughorn's incredulous look in her eyes, Elena continued unhurriedly.

"It is said that until the efficacy of the elixir wears off, it will be easier to succeed in whatever you do. However, the brewing process of the elixir is very complicated, and once you get it wrong, the consequences are unimaginable. But if you boil it properly, you should end up with a color like molten gold, and at the same time, there will be large drops of golden liquid on the surface of the potion, beating like goldfish, but not spilling out...... Is that so? Professor Slughorn. ”

"Well, yes, exactly the right answer. ”

Horace Slughorn opened his mouth and said in some surprise.

"Perfect answer, even I don't have much to add......"

Compared to Elena's advanced knowledge, what shocked Slughorn even more was the girl's judgment.

Determining the final form from a pot of potion liquid that has not yet been boiled is an ability that only a handful of Potions masters at the top of the industry possess.

Even if it were Slughorn himself, there might not be a way to be as sure as Elena.

As for answering by mistake?

Potions is different from other Hogwarts disciplines, and the books don't tell you everything.

Perhaps the medicinal effects and forms can be gained by reading a lot of books, but the specific descriptions in the crucible do not appear in the books.

This meant that Elena had seen the potion brew at least once, and it had to be a success—and it was strange when it happened to a young witch who had just entered her second year.

Unless......

Slughorn frowned, looked at Elena carefully, and suddenly said with a twinkle in his eyes.

"Oh, that's right!' Hogwarts also had a student who was an assistant teacher in Potions and was involved in the development of a series of rules. Severus had said that the Potions assistant he was talking about couldn't be you, Miss Caslana. ”

"Yes, Professor. Elena nodded.

"But only in the afternoon Potions class, where I was just a normal student. ”

"I see, I see, I ...... so"

Slughorn glanced at Elena with some greed, and nodded knowingly.

He suddenly remembered another gossip that Dumbledore had accidentally revealed before, in addition to Nicol Lemay, there was also a student in the school who had a very close relationship with another owner of the Philosopher's Stone, if nothing else-

"Very good, very good, all three questions were answered very well. ”

Slughorn said with a smile on his face, glancing at Elena's clothes, "Gryffindor and Slytherin, ten points each, and fifteen points for Ravenclaw House." ”

Huh?

Ravenclaw?

Elena was slightly stunned, and subconsciously lowered her head to look at the clothes on her body - it's over, in the morning, in order to pursue the effect of the speech at Ravenclaw College, she didn't have time to change her clothes, and all her extra points today have to be fed to the eagle.

Before Elena could figure out how to explain that she was wearing the wrong clothes, Slughorn continued.

"Now," Slughorn said, "the test is over, and we should start class!"

After learning a little about the situation of this group of demons, he didn't plan to continue asking.

As a Potions professor, he couldn't wait to see how well these kids practiced, after all, in the past few decades of Potions teaching, it was not without a little wizard who was fluent in theory but made mistakes in practice.

Severus Snape, for example, who is now a professor of Potions, was less consistent when he was a student.

Severus, while good at least compared to Lily Evans, struggled to be as consistent, delicate and brilliant as the Gryffindor Muggle Witch, and he often made a few mistakes in many places.

In Potions, non-rigorous and non-standardized methods are often the most fatal shortcomings.

"Please turn to page 57 of Magic Potions and Potions, today we are going to learn about an extremely common primary potion: a swelling potion, which will make the body of living creatures swell significantly, so you need to be extra careful not to splash the potion on your bare skin during the boiling process. ”

Horace Slughorn cleared his throat, his voice becoming serious.

"We've got a little more than an hour, so you're going to use that time to make a good swelling potion. I know it's not complicated for all of you, but every potion can be perfected. The person who completes the potion the fastest and best will earn twenty points for his house and receive a small gift. ”

At this, Slughorn blinked mysteriously.

"If all goes well, you'll be able to experience a wonderful, perfect day. ”

The chubby old wizard pointed to the small black cauldron that was tumbling beside him, and the meaning of it was self-evident.

"But...... Professor, why is it just a day?"

Terry Bout asked eagerly, staring fiery at the golden potion in the cauldron.

"I mean, why can't you drink it every day?"

"Because, if taken in excess, it can lead to vertigo, recklessness, and dangerous hubris. ”

Slughorn said, shrugging his shoulders a little helplessly.

"You know, more good things are also harmful...... In Potions, it is the most ridiculous situation to talk about the effect regardless of the dose. Any potion dose that is too large is very toxic. However, if you take it cautiously and sparingly once in a while, ......"

"So, have you taken it, sir?" asked Draco Malfoy with interest.

"I've taken it twice in my life," Slughorn said, "once at twenty-four and once at fifty-seven." I took two scoops at breakfast, and those two days were perfect. ”

As he spoke, he stared into the distance in a trance.

Draco felt that whether Slughorn was acting or not, it was tempting.

"Well, all in all......" Slughorn said as if returning to reality.

"When this elixir is successfully brewed, I will prepare a 'twelve-hour' dose of the elixir for the winners of today's course. For twelve hours, from dawn to dark, whatever you do, the stars will shine brightly. ”

"I must remind you, however, that elixirs are forbidden in organized competitions...... Such as sports competitions, exams or campaigns. Therefore, those who get the prize can only use it on ordinary days...... Then wait and see how unusual that normal day will be! Don't leave it to chance, many professors will be able to tell if you've taken a magic potion. ”

With such a naked temptation, the whole class involuntarily straightened their backs, raised their heads and looked at Horace Slughorn intently, even if he added it with great seriousness, it did not affect this temptation.

Perhaps in terms of exam scores and class answers, the little wizards led by Elena have always been in a dominant position.

However, in the practice of Potions class, the Moonlight Seven and Elena are not completely invincible, at least in the past year, there have been more than one time when other young wizards have reached a tie with them at the end of the class.

Of course, this is not because Elena and the others have become weaker, or careless.

This is mainly due to the fact that the upper limit of the Potions for beginners is not very high.

Under the strict and scientific rules and regulations of potions, most serious wizards were able to perfectly fulfill Professor Snape's requirements - foolish step-by-step instructions, uncumbersome processes, and basic potion handling...... Strictly speaking, Potions in the lower grades wasn't much different from Muggles' middle school chemistry classes.

So, when Slughorn came up with a way to win, the students' morale was almost ignited.

Apart from...... A white-haired dumpling that was a little distracted.

As the lucky one standing on the shoulders of giants, she had been paying attention to this legendary potion for a long time, and in the eyes of the fairy queen of Gringotts, the expensive and rare elixir in the wizarding world was not much different from ice cola ice in her eyes.

Compared to Slughorn, she may have a deeper understanding of the usefulness and limitations of this potion.

After all, at the end of the day, Horace Slughorn is just a good Potions Master.

With a precious potion like the Elixir with a long cool-down period, Slughorn had very little first-hand information, most of which was based on feedback from his own exchanges with a handful of friends.

In fact, the creation of any potion is actually the same logic as the birth of a new medicine in the non-magical world.

Without enough samples and time to test a potion, its results are often only superficial - which is why progress in potions has been slow for so many years.

Thankfully, since Nicol Lemay and Gellert Grindelwald joined her camp, these are no longer a problem.

The former has seen the erosion of time, while the latter holds the largest samples.

As Dumbledore sometimes unconsciously lamented, the wizarding world has nurtured thousands of years of civilization and accumulation, as if it had been specially prepared for Elena—with countless lines of fate intersecting at Hogwarts, the pace of the new era has never been so clear, and Elena is the luckiest of the era's doormen.

"If you're prepared to deal with a danger beyond your control, the Elixir may be of some use......

Nicol Lemay once commented on the Elixir, "But on the other hand, in addition to the seemingly common potion toxicity, it actually has a very hidden but particularly harmful price - the Elixir will overdraw your future 'inspiration' to a certain extent, or the creativity in your soul." ”

"Detailed ingredients and cooking notes—" Slughorn waved his wand, "—on the blackboard—"

(A detailed copy of the contents immediately appears on the blackboard behind the old wizard.)

"-Everything you need-", he waved his wand again, speaking more confidently and steadily, as if he was finding some familiar rhythm, "-in the locker-"

(The locker was also opened at once)

"So, let's get started. ”
