The Extraordinary Apothecary at Hogwarts

Eugenie did not dare to covet her warm hibernation nest at all, and her toes hurriedly found her shoes on the ground.

Snape lowered his gaze and caught a glimpse of her stepping on her heels, turning her leather shoes into slippers, but he was too embarrassed to put them on again now. He pretended not to notice and turned around to walk forward, holding down the wand with his right hand under the black robe, " According to Professor Dumbledore, the basilisk was seriously injured and escaped, and he wanted to let Potter face it alone."

Eugenie followed and took a few steps, then found that the heel of her shoe had returned to its original position.

"My personal concern is that it is doubtful that Dumbledore will choose to teach Potter Occlumency in person in the future, and it is even slimmer to expect that Potter will learn it, so if you say anything in front of him, there will be some risk of exposure."

"I understand, Professor." Eugenie looked at the eagle-shaped ring on her left hand, "I will not mention the relevant information to Harry. He has his mission, and I have mine."

"Yeah." Snape's eyes also paused on the ring for a short time, as if he was thinking about something. Then he walked to the table and sat down as usual, taking out a book with an interesting reading cover and placing it next to him.

Bright sunlight poured into the room, and the fonts on the cover shone golden.

However, the content has nothing to do with the cover. The pages have long been replaced with a transcribed version of Gringotts' ancient potion.

"Turn to page 84," Snape said.

So there was only the sound of flipping books in the room, and soon the sound stopped.

It is the medicine that will be used this time to imitate human organs.

The required ingredients are simply listed in italic runes immediately below the title:

Leech powder

unicorn horn

Sapweed

immortal jellyfish

Hagfish slime

salamander blood,

and a living, small part of the human body's organs.

That's all, and it doesn't look complicated at first glance.

However, the cultivation and selection of raw materials and pretreatment methods are filled with more than ten pages.

Eugenie held the book and read it carefully. Next to her, Snape placed the eleven harvested sapweeds in order - only the full moon of December was left to collect the last one.

Snape waited for her to finish reading the pre-processing chapter, and took the book away before she could read the production process. "What do you think? Combined with what you have learned before, talk about your current understanding."

"Bleedingweed and leeches are two ingredients also used in Polyjuice Potion."

"Yes, you already know the magical properties of these two materials."

Polyjuice was selected as the final exam content for the last semester, and then she was asked to learn the Patronus Charm on her own during the summer vacation. Every step was paving the way, a spiral of knowledge growth.

"The sap grass provides variability, and the leeches provide a diversion effect. The functions are similar here, but why are they-"

"Yes, similar." Snape saw that she wanted to ask a question, but made a don't say it yet gesture. "I see you left a question here, but let's put it down first and let's look at it first. Looking at several other materials, unicorn horn and salamander blood are also old friends and are widely used in many common magic potions.”

Eugenia nodded, "Salamander blood provides rejuvenating life energy, but Professor, I failed to understand the role of unicorn horn. Usually we use its therapeutic properties to purify and detoxify, and a few are used to resist paralysis effects—— But neither is needed here.”

"That's right, another of its magical properties is used here - no wonder you can't think of it. There are no examples of this property mentioned in modern potions. You need to analyze it as a whole to discover its beauty."

Eugenie pursed her lips unwillingly and thought for a while, analyzing the whole and making connections with other materials. What was missing or added in them?A unicorn horn is needed to balance or complete it.

Questions about sapweed and leeches were still lingering in her mind, and a new question arose.

If the unicorn horn was added to complement other necessary ingredients, then she should continue analyzing the remaining materials first.

Snape probably thought so too. He said, "Let's take a look at the remaining two first. Immortal jellyfish and hagfish mucus are the new medicinal materials you have come into contact with for the first time. The requirements for collecting them are mentioned in the part you have read. You can make a reasonable guess based on those requirements, what is their role?”

"Well - the first is the immortal jellyfish. Use the Illusion Charm to approach quietly to ensure that the jellyfish group is not disturbed, and then move quickly to stun them - this is to prevent them from being frightened and retracting into their sacs and turning into polyps - this The immortal jellyfish in this form has powerful replication and repair capabilities, and has the property of reversing aging."

Snape nodded slightly, "Continue."

"Use cod to trap hagfish, and take the mucus it releases after leaving the sea water. After adding this ingredient to the soup, it must produce a strong cohesion force, entangle all the liquids and form a gel - I think It must be in the last step, after putting in a part of fresh human tissue, and then use its polymerization ability to finally generate human organs."

Snape finally returned the book to her, "Logical speculation has led you to the correct conclusion. The preparation process is indeed the same. So, think about it again, what is the biggest difference between it and Polyjuice Potion?"

After analyzing the raw materials forward, we must then reason backward from the results.

"Polyjuice Potion allows one person to become another person, and imitation organs allow the potion to grow parts of the body that are exactly like one's own."

One is exactly the same as the other——

Eugenie felt that something blocked in her head was suddenly clear, and the answer was already on her lips.

understood!I understood it all at once!The unknown magical properties of unicorn horns!

She always looked like this when she suddenly realized something. Her eyes were bright, she looked up at the professor, and her nose moved forward involuntarily.

Snape stretched out his index finger to touch the tip of her nose, and she would suddenly fall off the chair again.

He knew that she already understood, but once he got the answer, his mind would immediately turn to other mysteries that needed to be solved urgently with this new gain.

However, these newly gained insights in the mind still need to be slowed down and smoothed out in an orderly and thorough manner before they can truly be absorbed into useful experiences.

So Snape slowly guided, "Yes, you see, the polyjuice potion uses a variety of magical materials to achieve this purpose: lacewings, amphora, bicorn horns, African tree snake skin, why? Choose these materials?”

She spoke eight times faster than before, "Lacewings, two-eared grass, two-horned horns - establish a bond between one person and another, allowing the magic effect to create duality."

Right, duality!

"What about the African tree snake skin?" Snape asked again.

"Get a new life!" Eugenie was already excited. The experience of peeling off the cocoon and then gaining enlightenment is always so exciting. She is also one step closer to the truth about other problems!

"Are these needed when making human organs? It comes from the person who provided the human tissue, and the thing made should be consistent with its original body."

"No, I don't want any materials like bicorn horns. Unification, it needs something that can strengthen unity! Unicorn horn! I really should have thought that it could have such a use."

After analysis, the principle sounds so simple, but when the vision is limited to the fixed perspectives of "unicorn horn must be added to the medicine required to prepare human organs" and "all books only mention that the function of unicorn horn is to purify and detoxify" At that time, I just couldn't uncover that layer of truth.
