"So, Professor, shall I continue to explain the subsequent knowledge of potion materials?"
Elena's eyes flickered and she asked sweetly.
"Oh, oh, of course, Miss Caslana," Slughorn said cheerfully.
The old walrus, who still didn't know that he had been written on the list by the Sandaime Dark Lord, blinked and gave Elena an appreciative look, indicating that the girl would continue to help him popularize potion knowledge according to previous progress.
With several questions and answers in the classroom, the students' interest has been completely aroused.
After realizing Hermione's challenge, Elena also had a more thoughtful mind in her subsequent description, and did not choose to continue to delve deeper into the field of potions. Instead, the conversation shifted to biology, which she was more familiar with.
As the Third Dark Lord, Elena would not be careless in such a "one hundred times" bet.
Tomorrow morning, Gringotts will send Hermione the extracurricular books she bought during the summer vacation. After she finds time to study them carefully, she can then counterattack and design traps in a targeted manner. This will be an upright and fair contest.
"Ahem, next I will focus on the dangers of puffer fish and bats..."
Elena cleared her throat, took out her wand and tapped the blackboard.
"In addition to inflating itself when encountering danger to deter the enemy, the most dangerous thing about pufferfish is actually the toxin it may carry - tetrodotoxin (TTX), which is the most toxic substance found in the non-magical world.
It is one of the most toxic neurotoxins in nature, and was even considered by Muggles to be the most toxic active toxin in nature."
"Just 0.48 milligrams of tetrodotoxin can easily take away a person's life. If someone here curiously licks the eyes of these pufferfish, or fails to wear gloves as required in the operating procedures, as long as you are a little bit unlucky and accidentally ingest it,
With even a tiny bit of poison, someone here may leave us forever tomorrow..."
Elena's eyes slowly swept across the classroom and she spoke calmly.
Her voice was only slightly higher than a whisper, but everyone heard every word she said clearly, as if a trumpeted Professor Snape suddenly appeared in the classroom, and the underground classroom instantly became orderly.
It became orderly.
poisonous?!
If you touch it even a little bit, you will die?!
Most of the little wizards subconsciously moved back, wanting to be a little further away from the pufferfish eyes that exuded a "venomous" aura. Due to the "big herring battles" that occurred last semester, Hogwart
The students can already handle the dead fish calmly. If it weren't for Elena's words, there might be many children who would do it directly.
And the face of a reckless boy like Michael Kohner turned even paler.
Just to save trouble, they just grabbed the puffer fish eyes and threw them into the grinding dish. Now with Elena's cold explanation, Michael felt his hands were a little hot, as if they were covered in hot chili sauce.
.
It’s really disturbing...these naughty kids at Hogwarts...
Elena glanced at the few little wizards who were secretly putting on gloves, and shook her head helplessly in her heart.
Only those who have actually served as a Potions professor—well, even though they are teaching assistants—will understand the reason why Severus Snape was so stressed and irritable in every class before. Unlike other classes, the Charms class was trying to die.
There are so many ways to do it. If you are not careful, just a slight wound may directly send these little guys to see Merlin.
Tetrodotoxin (TTX) is a highly toxic marine biologically active substance.
Tetrodotoxin includes tetrodotoxin, tetrodotoxin, tetrodotoxin and puffer fish liver toxin. It is one of the most violent toxins in nature. Its toxicity is equivalent to 1250 times that of potassium cyanide. It can cause central nervous system anesthesia in a short time.
If people handle pufferfish improperly or eat it by mistake, poisoning or even death can occur.
And this is only the potion materials involved in the junior potions class. In the teaching of the upper grades of Hogwarts, as potion materials begin to appear more and more "magic materials", the dangers are doubled.
The ground rises.
As a young wizard with less than ten years of tenure, Snape had too much to worry about in Potions class.
Fortunately, at least in today's world, there will not be a second batch of super invincible kids like the "Iron Triangle" who will steal potion materials and throw them into other people's cauldrons in the potions class.
It took a lot of effort to pull out the fireworks.
If you think about it this way, she is really a great and kind little angel.
If it weren't for the fact that she couldn't claim credit, just by easing the relationship between Harry and Snape, Elena felt that she could ask Severus Snape to receive a large amount of college points, and even the Shenfeng Wuying etc.
How to release the curse.
"However, the chemical and thermal properties of tetrodotoxin are very stable. Although general cooking methods such as salting or sun-drying cannot destroy it, if it is heated in a high-temperature environment for more than 30 minutes, the toxin can usually be decomposed..."
The kind little angel paused for a few seconds, waited patiently for Hermione to finish taking notes, and then continued to speak.
"Therefore, if you don't want to die tragically due to an accident, it is best to strictly follow the process recorded in the textbook, put the mixture of puffer fish eyes and nettles in the crucible, and boil it at high temperature for at least 45-60 minutes before proceeding -
And during this process, even if you feel a little thirsty, you must not pay attention to the hot soup in front of you."
Perhaps in the magical world, wizards' research in the microscopic field is not that profound, but this does not mean ignorance.
As supernatural beings who control magical powers, wizards have a much easier time trial and error than Muggles.
If boiling for one hour weakens the toxicity, then two hours. If two hours doesn't work, then six hours... Anyway, as long as you pay attention to detoxification at all times and take countermeasures in advance, even one person can do it by tasting.
Summary of magic potions.
If in the end nothing works no matter what you try, then add new materials or use magic to make adjustments.
Potions science progresses slowly, but that doesn't mean people can't use the stupid method of repeated experiments to generalize answers.
Even for the most basic potion like Swelling Potion, the control of time and temperature is undoubtedly the final preparation process that generations of potion masters have spent countless hours gradually exploring and determining.
.
“Not bad at all!”
Slughorn nodded, cleared his throat, raised his finger and added seriously.
"Time and temperature, please pay attention to these two points! Unless you think you are better than all potion masters, don't take any shortcuts in this regard. What's more important is the way you handle potions.
The former determines the quality of the potion you finally produce, while the latter is related to whether you can safely complete the entire potion brewing process."
"But, professor..."
At this moment, a Hufflepuff boy with curly hair suddenly raised his hand.
"I have eaten pufferfish with my mother many times before, well... in the non-magical world. If this pufferfish is really as dangerous as you and Sister Elena said, why are so many people eating it outside?
?”
"Huh? Have you ever eaten puffer fish? Sorry, sir, what is your name?"
Slughorn raised his eyebrows and glanced at the strange little wizard casually.
Although he does not discriminate against those Muggle wizards who come from the non-magical world, Slughorn still has some extremely subtle superiority and helplessness whenever he encounters such little guys who use Muggle knowledge to question magical knowledge.
.
"Justin, my name is Justin Finch-Fletchley, professor."
Justin replied quickly, looking at Slughorn openly and said, "I come from a non-magical world. Although my parents are not magicians, my family is living a pretty good life. Sometimes when they attend banquets or entertainment
, will also take me with him. In my impression, although puffer fish is not often eaten, we should have eaten it several times."
"It's not surprising. Muggles always covet the immediate enjoyment and fail to see the hidden dangers."
Slughorn frowned slightly and answered casually impatiently.
"Okay, Mr. Finch-Fletchley, if you know more about the potion material of pufferfish, you will understand that toxins may appear anywhere on its body. This is the experience summed up by countless potion masters after trying it.
…Don’t you think that Muggles know how to deal with these poisonous creatures better than wizards?”
"But we..."
"That only means you are lucky and have not encountered those toxins."
Horace Slughorn waved his hand impatiently, interrupting Justin Finch-Fletchley somewhat harshly.
"You are a wizard now, sir - if you are still going to argue with me on the basis of Muggle knowledge, I suggest you think carefully about why you chose to come to Hogwarts to study magic instead of continuing in the Muggle world.
go to school."
Strictly speaking, Slughorn does not discriminate against Muggle-born wizards.
In his eyes, students can be roughly divided into three types: gifted and talented rising stars; living elders in the family who are celebrities worth making friends with; and... other ordinary students.
There is no doubt that Elena is clearly the top two overlapping items among the first two.
Although Harry Potter has the aura of "The Boy Who Lived", due to the orphan factor, his score in the heart of the old walrus has been slightly reduced. However, judging from the current performance of little Harry, he has inherited her mother's
As for magical talent, it would rank high on Horace Slughorn's "little list".
Other than that, the little guy from the Malfoy family is pretty good.
Although old Malfoy, Draco's grandfather, Abraxas Malfoy, unfortunately died of dragon plague syphilis, which once made the entire Malfoy family somewhat disgraced among pure-blood wizarding families. But over the years, in
Under the guidance of Lucius Malfoy, he gradually regained some voice in the magical world.
I heard that just some time ago, Lucius Malfoy even successfully joined the Hogwarts school board.
As for Mr. Justin Finch-Fletchley...
Horace Slughorn glanced casually at the parchment under the lesson plan.
Those were the final exam results of the batch of freshmen at Hogwarts last year that he finally managed to get, and Justin Finch-Fletchley barely ranked in the mid-twenties, an area that was neither good nor bad.
Considering that this little wizard comes from the non-magical world, of course, he should be regarded as other ordinary students - and he is still ranked low among ordinary students. After all, this little guy just contradicted him stupidly.
.
"Mr. Finch-Fletchley, I suggest that you don't try to be clever like this in the future, and don't try to find shortcuts in the non-magical world."
Slughorn raised his finger, lowered his head and looked at the little boy, and said in a deep voice.
"As for the processing of fugu-related potion materials, the magic world has long had a complete process. Unfortunately, there is no corresponding material in the classroom, so I can't demonstrate it to you, but you can check the information in the library - I will question it later.
Before asking questions, it is best to learn from Miss Granger, at least from magic books, not Muggle knowledge."
"Sorry, Professor, I will pay attention to it later."
Justin Finch-Fletch's face turned a little red, he glanced helplessly at his silent companions around him, and sat back in disbelief.
Whether in the non-magical world or the magical world, students can always clearly feel the attitude of their professors.
After clearly sensing the impatience in Slughorn's tone, even the few wizards who had a relatively good relationship with Justin Finch-Fletchley in the past did not help to refute at this time, and there was a low voice in the classroom.
of laughter.
What a... extremely realistic social person, Professor Slughorn.
Elena raised her eyebrows and looked at the old wizard who was completely different from the other two with amusement.
Unlike those students who don't know Slughorn yet, she really understands Slughorn's character very well.
When the old wizard was in the original work, he was treated with such an unabashed distinction - although Horace Slughorn did not have any malicious intentions, neither in terms of student education nor in terms of right and wrong.
question.
But in Elena's opinion, this kind of overly snobbish division makes people feel a little bit unhappy after all.
Not to mention, if we just talk about family background, Justin Finch-Fletchley, who almost entered Eton Middle School, is one of the few "true nobles" in Hogwarts. This is why Elena remembers this little transparent person.
One of the reasons.
Although usually, power and status in the non-magical world do not have much significance in the magical world.
But when the accumulation of a family lasts for a long enough time, especially when the two worlds begin to show signs of merging with each other, the "aristocratic" class like Fenglili becomes particularly important - right now
During the summer vacation that just ended, some of the Fin-reli family's properties have gradually appeared on Gringotts' attention list.
When the time is right, they will serve as the first bridges to connect the two worlds.
In this process, the attitude and stance of little wizards like Justin Finch-Fletchley may not become the key point in leading world change, but it is not completely insignificant, and more importantly...
Elena glanced at Horace Slughorn thoughtfully, and raised the corners of her mouth slightly.
Times have changed, professor.
"Actually, I can help answer Justin's question, professor."
Just when Justin Finch-Fletchley lowered his head nonchalantly, looking at the textbook in front of him, awkwardly avoiding the sight and low laughter of the students around him, a few words that sounded like the voice of an angel suddenly floated from the desk in front of the classroom.
the sound of.
"The non-magical world's research on the toxicity of tetrodotoxin is not much behind the magical world. To be more precise, they are even slightly ahead of our current textbooks when it comes to classifying the dangers and toxicity distribution of tetrodotoxin."
Sister Elena?!
Justin Finch-Fletchley quickly raised his head and looked expectantly at the front of the classroom.
Elena took out her wand and waved it gently beside the blackboard.
The next moment, the pattern of a puffer fish appeared in front of everyone's eyes. Along with Elena's explanation, it was gradually decomposed on the blackboard and disassembled into parts. A series of text explanations were attached next to the decomposition diagram.
"According to the latest research in the non-magical world, the toxicity distribution of puffer fish is mainly characterized by the following five characteristics..."
"First of all, the toxin content in different parts of the fish body is different. Generally speaking, the ovary of the puffer fish contains the most, followed by the liver, and the blood, eyes, gills, and skin all contain a small amount. The muscles actually do not contain tetrodotoxin. However,
After the pufferfish dies, the toxins in the internal organs may seep into the muscles, resulting in occasional small amounts of toxins appearing in the muscles..."
"...(Four points left, click here to expand)"
Elena paused briefly and looked at Horace Slughorn with interest.
Unlike Justin's impatience when speaking before, the Potions professor did not interrupt her. Instead, he looked at her with approval, while carefully watching the girl use magic on the Potions blackboard with interest.
Drawn writing on the blackboard.
Tsk, tut, tut...
This is really an extreme level of discrimination!
As a vested interest in all evil, Elena curled her lips with a complicated expression.
But one thing is certain, compared to Severus Snape, Horace Slughorn is obviously more tolerant of gifted students, but does not have that much concern for the Potions class itself.
Obsession, in that case...
“In addition, puffer fish meat has a delicious flavor, is tender and thornless, and has a very high protein content.”
Elena made a decision in her heart, turned the wand in her hand, and continued speaking seriously.
"As a top-quality seafood with richer nutritional value than other fish, it can be said that mastering its toxic treatment methods and simple cooking precautions is quite meaningful for understanding and utilizing the value of puffer fish."
Um?
Uh-huh?
Horace Slughorn blinked in confusion.
Why did he feel that something was not quite right in what the little witch said just now?
However, before he could realize what was wrong, Elena went on to introduce it with excitement.
"Generally speaking, fish are the freshest within 4-5 hours after death. After that, the meat will become stiff and affect the taste."
"The puffer fish is different. Its meat is originally firm, but it will soften 24-36 hours after death. It is best to eat at this time and has the smoothest texture. Now you can feel it first..."
Well?
Feel it?
What does it mean...to feel it?
Before Professor Slughorn could ask, the next moment, mist suddenly rose in the Potions classroom.
Along with a series of weak magic fluctuations, two large golden dinner plates appeared almost simultaneously on every desk in the underground classroom. In the center of the golden dinner plate was a cup of snow exuding an alluring aroma.
White soup.
Similarly, an identical set of golden dinner plates appeared on Slughorn's desk.
What's this……
Slughorn raised his eyebrows, picked up the delicate little bowl and looked at it carefully.
In the milky white soup, there are a few pieces of crystal clear fish floating in it. The rich fish soup has a faint aroma of milk and beef. Shake the small bowl a little, and the soup is as viscous as gelatin.
I couldn't help but swallow my saliva.
"It's just a very simple white puffer fish soup. The Hogwarts kitchen has been cooking it since morning."
Elena waved her hand quite casually and smelled the soup bowl in her hand with satisfaction.
Sure enough, she spent all the effort to purchase a batch of puffer fish, and asked Gilderoy Lockhart to lead a group of non-magical chefs to help with their treatment. The aroma of this fragrant and mellow fish soup was really the best thing in the morning.
Delicious soup.
Of course, the reason for purchasing this batch was not to eat puffer fish.
As the headmaster of Hogwarts, Elena was originally responsible for the purchase of teaching materials for Hogwarts.
In the Potions class, many potions are used on various parts of the puffer fish. Considering the cost accounting issue, it is obviously quite reasonable to purchase a batch of whole puffer fish directly from a professional breeding farm in the non-magical world.
"In order to enhance the umami taste, I asked the kitchen elf to add a small amount of butter and milk. Other than that, except for a little white pepper and salt, there are no additional additions. The most authentic pufferfish soup.
.”
The magic wand in Elena's hand waved slightly, and the writing on the blackboard in the classroom changed again.
The main body of the pufferfish originally located in the corner quickly grew in size and was cut into pieces, and then a series of auxiliary materials, as well as cutting, manipulation, and cooking techniques appeared around it, echoing the process of brewing the swelling potion on the other side of the blackboard.
"Wait, this, I mean, this soup - the Hogwarts kitchen?"
Slughorn held the steaming bowl of puffer fish soup in his hand and felt a little confused for a moment.
"Oh, I forgot to introduce you. I am the chef of the Hogwarts kitchen, Professor."
Elena blinked in realization, blew the hot soup in her hand, and explained in a brisk tone.
"Don't worry, this is a new tradition of Hogwarts Potions. Whenever new potions materials are involved in teaching, the Hogwarts kitchen will introduce corresponding or similar materials under the guidance of the Potions professor.
Style dishes.”
"This is mainly to enhance everyone's understanding of potion materials...Professor Dumbledore also agreed."
As Elena spoke, she raised the soup bowl in her hand and took a sip.
"Professor, please drink it while it's hot. This is a specialty of Hogwarts - there are still nearly twenty minutes until the second reaction time of the swelling potion. After you finish drinking the fish soup, you can take everyone with you.
Let’s deal with the puffer fish together.”
"Deal with... pufferfish?"
The smile on Slughorn's face froze slightly and he repeated politely.
"Yes, didn't you just say that wizards know how to handle blowfish better than Muggles, but there is a lack of objects to demonstrate and learn from in the classroom, so we can only let everyone read the books after class to understand?"
Elena winked mischievously at Justin Finch-Fletchley, who was not far away, and then raised her head to look at the old wizard.
"It just so happens that there happens to be a batch of unprocessed puffer fish in the Hogwarts kitchen..."
As the girl's voice fell, a large box suddenly appeared in the open space at the front of the classroom.
Inside the box was filled with pufferfish that had been euthanized by magic. Dozens of dull fish eyes stared blankly at Slughorn. The dull fish eyes reflected the expression of the old walrus with the same dull expression.

Woohoo, the network is stuck, I almost didn’t send out the message, Fat Gugu was panicking~
I originally wanted to divide it into two chapters and leave some updated manuscripts for tomorrow, but I didn’t have time to divide it into sections... I had to post it in one go...
