"Potter!" their professor said suddenly, "what do I get if I add hyacinth bulb powder to the saliva of a Madeira snail?"

Harry glanced at Ron, and the two of them were visibly stunned. Pen, fun, and www.biquge.info

Vio was also at a loss, what was added to the saliva? These small things must have appeared in the book, but she didn't remember.

Taking a step back, even if she remembered the answer to this question, Rowling did not write specific exam questions and answers in the book, and she couldn't avoid the exam in the first year of junior high school.

She sighed in her heart, it seemed that if she wanted to stay well, she really had to be like Harry and the others, and take the class seriously and complete her homework.

In the entire class, only Hermione raised her arms in the air, and Draco Malfoy's mouth curled slightly, scanning the class with a mocking look, and although he didn't raise his hand, he seemed to know the answer.

"I don't know, sir. Harry replied honestly.

Professor Snape pursed his lips contemptuously.

"One more chance, Potter. If I asked you to find me a plant of Aconite, where would you find it, tell me about your steps. ”

Hermione raised her hand higher when she heard Snape ask another question, and Vio stared nervously at Harry, who she instinctively knew would still get him wrong. Harry looked at Professor Snape and whispered, "I don't know, sir, but if you really need it, I think I'll go to the herbalist and get it for you, sir." ”

Hermione looked at him in surprise.

The whole class laughed, but they all tried desperately not to laugh, especially after Snape's indifferent glance around, almost no one grinned anymore.

But the other boy winked at Harry, motioning for him to say no more. Vio glanced at the nameplate in front of his robe, Seamus Finigan, of Gryffindor House.

"Good, good, rich Potter!" Snape scolded, visibly upset, "I suppose you haven't opened a book before school starts, have you, Potter?"

"Draco, you tell him what the correct answer is. Snape deliberately ignored Hermione's arm, which had not been lowered, and walked over to Draco.

"Yes, Professor. Draco nodded and stood up, throwing an inexplicable smile at Harry.

"The addition of hyacinth bulb powder to the saliva of Madeira snails can be formulated into a very potent analgesic, which is a serving of Ping An water. There are many kinds of aconitum, which one do you need, Professor?"

"One strain each of Aconitum scapulata, one Aconitum lupus venomicide, and one Aconitum lucidum. Snape looked at him, noncommittal.

"Professor, if you are not in a hurry to use them, I will go to the dense forest swamp of Elti and bring them back, and if you are in a hurry, I will ask Professor Sprout for two scaphoid aconitum or two lupus venom aconitum and one sweet green aconitum - because scaphoid aconitum is lupus venom aconitum and they are plants of the same genus and species, collectively called aconitum manificiae. Draco replied with a smile, looking at Professor Snape confidently.

Sure enough, the professor seemed pleased with the answer he had given, and nodded at him, "Sit down, Slytheringa." Then he turned and said, "Do you all understand, why don't you write it all down?"

No one spoke, only the rustle of quill and parchment.

For the rest of the Potions lesson, Snape divided them into pairs and instructed them to mix a simple potion for scabies.

The Gryffindor students were grouped, Hermione was grouped with Neville, the kid who had lost the toad on the train, Harry and Ron, and Vio was standing beside his cauldron a little bewildered.

Snape glared at her—
