With "Professor Snape" gone, Matthew also divided five by two and finished breakfast.

Then he glanced at the class schedule, the first class of the morning was a herb class, Slytherin with the Hufflepuff students.

Matthew, Malfoy, Notte, Crabbe, and Goyle, the five of them, walked out of the castle together. They walked through the garden in the direction of the greenhouse.

As they approached the greenhouse, they saw many students waiting at the door of the greenhouse.

Just as they were about to join them, a familiar figure emerged from the greenhouse.

It was Professor Horace Slughorn, the Potions teacher and head of Slytherin House, who was holding a large handful of leaves in his arms.

"Oh, Matthew, and Draco......" Slughorn shouted eagerly as soon as he saw the students standing here.

At the same time, he automatically ignored Notte, Crabbe, and Goyle.

"Good morning, Professor Slughorn!" Matthew and Malfoy said in unison.

"yes, nice morning. Slughorn seemed to be in a good mood: "Such a fresh air, the day is in the morning, isn't it...... Maybe I'm going to test you, guess what?"

As he spoke, he waved the large handful of leaves in his hand.

Matthew leaned over and looked at it carefully for a moment, "It's Swift Grass, right?"

"That's right!" Slughorn nodded with satisfaction, "Most authorities agree that this medicine is best picked in the early morning, and I have to say that Pomona (referring to Professor Pomona Sprout, the herbalist teacher) made them grow to perfection...... I think the third graders will each get a few slices, and some of the remaining ones to prevent someone from overcooking them...... You'll be using it this time next year!"

"I'm looking forward to it, Professor. ”

"Okay, I'll have to deal with them in the office...... By the way, Matthew, Draco......" Professor Slughorn had already turned around, and then he suddenly remembered something, "By the way, this Sunday night, the Slug Club party will be back in action, don't you forget......"

“...... Be sure to be on time!" he walked farther and farther away, and his voice became quieter and quieter.

The Slug Club is a club founded by Professor Slughorn himself, which only houses the students he admires, and Matthew and Malfoy are members of it.

They have a small meeting every week, or every two weeks, usually on the weekend.

However, in October last year, two Slytherin members of the Slug Club were attacked on their way back to the Slytherin common room from Slughorn's office late at night due to a party...... Due to this accident, the Slug Club meeting was temporarily suspended.

By the end of the semester, even the culprits of the attack had fled, and Professor Slughorn had not recovered.

But now that the new semester has begun, the impact of the attacks more than half a year ago has been minimized.

So, the party started again.

......

Professor Slughorn's figure faded from their view.

"Come in, boys!" and then, Professor Sprout's voice came from inside the greenhouse.

The Slytherin and Hufflepuff students hurriedly walked in.

Professor Pomona Sprout is a dwarf witch with a patched hat in her gray-gray hair. She had a slightly scruffy appearance and a lot of mud on her clothes and nails, but everyone knew that she was a very kind teacher.

"Today we're going to the third greenhouse!" she said happily.

The students were very interested in the discussion, having only been to the first and second greenhouses before...... Thirdly, the plants in the greenhouse are more interesting and more dangerous.

Professor Sprout removed a large key from his waist and opened the door. Matthew took a step forward, and suddenly he smelled a smell of damp earth and fertilizer, mixed with some faint floral scents.

The aroma was slightly intoxicating, and Matthew couldn't help but feel a little dizzy...... His face changed, and he hurriedly took a few steps back and exited the greenhouse.

He was not the only one who had such a reaction, but the other students who stepped into the greenhouse were unsteady one by one...... There were even a few people who looked like they were drunk, and their faces were flushed.

"Back off, boys, all back off!" Professor Sprout shouted with some excitement as he waved at them, "I didn't let you in!"

Hearing Professor Sprout's words, they all hurriedly exited the third greenhouse.

After a few breaths of fresh air, Matthew felt like he was feeling much better.

......

Professor Sprout also walked out, holding a large pile of large and small masks in her hands.

"I didn't pollinate the Flor flowers today," she said. Now, can anyone tell me what are the properties of the Flor flower?"

Matthew had already guessed what the plants in the greenhouse were, but before he could raise his hand, the other small hand was already raised.

"Very well, Miss Lestrange!"

Agnes Lestrange stood up and said very naturally, "The Flor flower, also known as the tracking flower, the mature Flor flower, its top petal has a deep connection with the rhizome...... Even if it's been out of the body for a while, the rhizome will still point in the direction of the petals......"

“...... So you can put fresh Flor flower petals next to something important, and if they are stolen, you can use the rhizome of Flor flower to easily track them down!"

"Well said, girl," Professor Sprout nodded in satisfaction and motioned for her to sit down, "in the meantime, the Flor flower is a very dangerous herb, does anyone know why?"

Agnes seemed to hesitate for a moment, but Matthew had already raised his hand first.

"Tell me, Mr. Wakefield. ”

"Its pollen is highly toxic. Matthew replied succinctly, "Enough to kill people." ”

"That's right!" Professor Sprout nodded, her voice calm, "The pollen of the Flor flower is highly poisonous, and if you inhale too much of it, it can be fatal...... Of course, the Flor flowers we're going to touch today are very young, but if you suck their pollen into your nose, you'll be in a coma for at least a few hours. I don't think any of you want to miss the first day of school!"

She then handed out the masks to the students.

"Remember, everyone should wear at least four masks, don't be lazy, and don't leave anything to chance......" she commanded loudly.
