Harry looked at Snape, expressionless, neither denying nor admitting to Snape's question.
Snape looked at Harry and became certain of his guess: it must be that damned Sirius Black!
He glanced down at the book on the table, then at Harry, his gaze lingering on her face. "Are you sure he was injured by Fantastic Beasts?"
Harry didn't answer directly, "I have similar symptoms."
Snape was silent for a moment, then stood up, walked to the cabinet in the corner, opened the drawer, took out a roll of parchment, placed it on the table, dipped a quill in ink, and began to write.
He wrote very slowly, as if he was adjusting the proportions as he wrote.
After finishing writing, he placed the parchment on the table without pushing it towards her, simply leaving it there. "This should be the recipe, but I'm not sure how effective it will be. However, I don't think your wizard friend will mind."
Since it was Black was going to use it, Snape didn't care about the effect. He just needed to restore the Potions recipe in the notebook. As for the Potions to treat the injuries of Fantastic Beasts, Snape had a better recipe himself. It was fine for Harry to use, but Black? Hmph, he was lucky he hadn't poisoned him.
When Harry reached out and took the parchment, she glanced at the paper. The handwriting was thin and smooth, and the list of materials and steps were neatly arranged.
Just as she was about to turn and leave, Snape spoke up again, perhaps fearing that something might go wrong with the Potions and that Harry would hold a grudge against him. He added, "If your friend was really injured by Fantastic Beasts, he'd better come to Hogwarts himself, if he dares to come."
Harry didn't understand what he meant, but she still casually replied, "It's not convenient for him to come."
Snape didn't press further, but simply sat down again. "Then carefully read the steps on the recipe, and don't make any mistakes."
Harry put the parchment roll into her pocket, then paused at the door. "Professor, that book..."
Snape glanced at her, reached out and closed the dark red-covered book, picked it up and placed it on the corner of the table, his tone flat and emotionless. "Forbidden books are not suitable for students to keep. I will deal with them."
After saying that, he didn't look at her again, but lowered his head and turned a page of the book in front of him, as if the matter was over.
Harry stood silently in the doorway for a moment, her gaze lingering on the book on the corner of his desk, before she opened the door and went out.
After she walked out of the corner of the corridor, she unfolded the parchment and looked at it again. Next to the list of ingredients, there were several lines of small notes, such as "grind evenly, do not put it in the pot at too high a temperature," as if Snape had added them after he finished copying them.
Harry carefully put away the parchment and walked back down the corridor at a leisurely pace. When she returned to the common room, Herman and Draco were still not back. She sat down in the armchair by the fireplace, opened another book she had brought back from the Restricted Section, tucked the parchment roll into her clothes, and waited for them to return.
Herman looked at the writing on the parchment scroll, then looked up at Harry: "So this recipe actually came from the Restricted Section?"
Harry didn't answer directly, but simply snatched the parchment back from his hand, unfolded it, and glanced at its contents. "The notebook I had was from the Restricted Section; the recipe was added by Snape based on that."
Herman pressed further, "Reliable?"
Harry didn't say anything, but simply reached out and pressed on the wound on his shoulder.
Herman gasped in pain, his shoulder jerked, and he swayed half an inch to the side, wincing in agony and unable to speak.
Harry withdrew her hand and said calmly, "Do you have a choice?"
Herman stretched his shoulder; the dull ache was still there. He gritted his teeth. "Fine, I'll give it a try."
He paused for a moment before speaking again, "But I still want to ask, aren't there any treatments for this kind of injury in the official textbooks?"
Harry leaned back in her chair. " Potions have always been a monopoly. The best recipes are all in the hands of Potions Master. Even Dumbledore, the professors can only teach you the basics of the common recipes. These powerful healing potions are the secret treasures of each household, and they're not easily passed on to outsiders."
She paused for a moment, "I was lucky to find a notebook in the Restricted Section that happened to contain relevant information."
Herman listened for a moment in silence, then said, "Okay, thank you."
Harry turned a page of her book. "You're welcome. Just don't blame me if anything goes wrong during the refining process."
Herman paused, then asked, "What do you mean?" Harry glanced at him. "It means this recipe is quite difficult to make. It requires many ingredients, detailed steps, and precise control of heat. Any deviation in any step can lead to failure or a reduced effect. Don't expect me to succeed on the first try, or for the medicine to be very effective."
Herman looked at her "I'm telling the truth, not being modest" expression and thought to himself, although Harry is indeed talented, even the most gifted person can't go straight to competing for the Nobel Prize in Mathematics after just learning that one plus one equals two.
He turned to Draco: "Any news from your family? About the Potions?"
Draco put down her notebook, her expression somewhat hesitant to speak, "My father is looking, but this kind of wound can actually be treated at St Mungo's Hospital for Magical Maladies and Injuries, so very few Potions Master are willing to specifically craft this kind of potion. The materials are expensive, the success rate is low, and there's not much profit to be made."
Herman was silent for a moment after hearing this, then said, "I'll go find Madam Pomfrey." Herman decided that confessing would be better than amputation or drug trials.
Draco quickly added, "I've inquired. Madam Pomfrey probably can't handle this kind of injury; you'd need a professional healing wizard. Hogwarts doesn't require the school nurse to be able to treat Fantastic Beasts bites during the hiring process."
Herman opened his mouth, as if to say something, but then closed it again. Finally, he turned to Harry and said, "Come on, let's see what materials we need."
Harry nodded in satisfaction, unfolded the parchment and laid it on the table, pointing to the contents with her finger. "A few basic materials, Moonstone Powder, Unicorn Hair fragments, are available in the student storage room. Just grab some extra when you're in class."
These kinds of powders—snake fang powder and dragon bone powder—aren't cheap, but they're not uncommon either. Snape should have them in his private vault.
Her finger moved to the end of the list, "But these last few might be a bit troublesome: Ashwinder Egg, Ashwinder Scales, and Mandrake Root. They're not the most expensive, just rarer, and not always available on the market; you'll need to go out of your way to find them."
Herman looked at where her finger had stopped. "Let's get the materials now, I'm afraid I won't be able to wait until Potions Class."
Draco immediately stood up. "I'll write to my father and ask him to buy it."
Herman shook his head. "Let's not trouble Uncle any further. Let him continue searching for Potions. I'll figure out the materials."
Harry turned to look at him. "You know someone who sells materials?"
Herman thought for a moment, "I don't know anyone who sells materials, but I do know a little Goblin who's obsessed with money. She'll dig up anything for you as long as you have money."
