The next day, Professor Sprout looked at a large number of students and told them that they would finish the book "A Thousand Magical Herbs and Mushrooms" by the end of the third grade, and hoped that they would listen carefully, otherwise they would have a hard time learning by the end of the fourth grade, and then took them to the third greenhouse.

McGoth had gone to Greenhouse 2 when he was in his first year, and he thought it was the place where he studied herbs in Grade 2, but he found out that it wasn't in herbal medicine class last year, and this year he jumped directly to Greenhouse 3, which seems to be a special place at Hogwarts.

On the way, a young wizard curiously asked Professor Sprout why he didn't go to Greenhouse 2, and she replied that a rare and addictive plant was cultivated there, so they knew that they would not be able to enter until the fifth grade.

Originally, everyone was very curious about Greenhouse Three, but after Professor Sprout's explanation, many young wizards were eager to turn their heads and go to Greenhouse Three.

Hearing that the second greenhouse had to wait until the fifth grade to enter made him subconsciously turn his head to look at Hermione behind him, only to find that Hermione was not behind him, and he didn't see her after looking left and right.

Before he could go to Harry, Greenhouse Three had arrived.

Professor Sprout stood on a raised mound of dirt and shouted at them to silence them.

"After everyone goes in, remember to put the mask belt at the door as soon as possible, and cast an armor shield on themselves, and decide how long they will stay inside according to the duration of their talisman charm, this is very important, do you hear it?"

For the first time, the little wizards heard that they had to add a layer of defense to themselves in class, and they couldn't help but look at each other. It wasn't until Professor Sprout asked aloud a second time that they reacted and said yes loudly.

"Very good, now the five of them will go in order."

McGoth wanted to find Harry, so he slowly dragged it to the end.

"Where's Hermione?" Without waiting for Magos to ask, Harry spoke first.

"She must have been in a long time ago, no one is more serious than her."

Magos shook his head,

"I was with her just now, but then I didn't know where she went, and she was definitely not at the front, so I specially looked for her."

"You guys, hurry up and get in." While they were talking, the little wizards in front of them had already entered the third greenhouse.

"Let's go in first." McGoth and the others had no choice but to stop talking, and at the urging of Professor Sprout, they entered the cloth door of greenhouse three.

Looking at the last five masks, he picked up one at random, and when he turned back to continue talking to Harry, Hermione picked up one from his left hand side and said how he was struggling.

McGoth looked at Hermione who suddenly appeared thoughtfully, and he seemed to have a little impression of why she had more homework than others and suddenly appeared in class.

"Where did you just go?" Ron asked strangely as he looked at Hermione, who had cast a talisman spell on him.

"I'm not around you all the time."

"But we didn't see you."

"Because I didn't see you either, well, if you don't get ready, I think Professor Sprout will be angry."

Sure enough, Professor Sprout looked at them with a little dissatisfaction, and hurriedly put on his mask and cast a talisman charm.

Sprout withdrew his gaze and let them enter the second wooden door. And again make them pay attention to the duration of the talisman charm.

"Is there danger in there? More dangerous than last year's mandrake? Ron's words sent Neville shudder.

After entering the wooden door, the light inside was a little dim, but the pots of herbs on the table emitted a faint fluorescence.

"It's beautiful." The little wizard at the front couldn't help but let out an exclamation.

They walked in and saw that it was very beautiful, and they saw that there was a fern with the length of their little arm growing on each pot, this plant was very peculiar, it seemed to be composed of several huge maple leaves with only three prongs, each leaf was composed of two green leaves and one leaf with a light blue glow, very beautiful.

Once each of the young wizards was standing in front of a potted plant, Professor Sprout stepped to the front.

"The plant that you get to know today is it, the three-leaf dream grass, also known as the dream leaf grass. It is a relatively dangerous plant, a small amount of contact at most makes us drowsy and want to sleep, once you encounter this kind of plant on a large scale, you must remember that you must stay away from them as soon as possible, because at that time, they can make you forever immersed in dreams and unable to wake up. ”

Hearing this, the little wizards who were gently touching it were frightened and quickly retracted their hands.

"The purpose of the amulet is to block its effects on you, and the mask is to block its scent."

"Of course, there are advantages to it, it is also a very important plant, in addition to being used to make coma potions and narcotics for wizards, it also has one of the most important uses, that is, it is also a very versatile catalytic plant, which can strengthen many kinds of potions, I won't say which potions can be strengthened, and your Professor Snape will teach you later."

As she spoke, she pulled the leaves of the three-leaf clover with her hand, and its three-petaled leaves shrank like mimosas, and then she used the same time to retract all the leaves in the pot.

"One of the things you can do is to show its health, and if it doesn't retract, it means it's sick. The second is to shrink it so that it will be much less dangerous, and they can be fertilized and a few leaves can be harvested. Remember, this doesn't mean they're not dangerous, but they're much smaller, especially if they're harvested as fast as possible, otherwise they'll release as much hypnotic gas as possible. Alright, now you guys try to change the soil for it. ”

Magos tried to pull at its leaves, but it couldn't move.

"Are you sick?" Harry tried his own, and the result was the same as him.

They looked at Ron and Hermione's operation with some confusion. The result is still the same as them.

They looked at the little wizards around them, and saw that no one could get its leaves to retract.

Sprout smiled at the helpless little wizards, and didn't tell them the reason now.

McGoth tried to tap the leaf with his wand, but not only did the leaf not retract, but it shook a few times, and he felt that it might have just released hypnotic gas.

Professor Sprout spun around and nodded unsuccessfully at all of them.

"I think you must be wondering why I did it and you can't."

As she spoke, she paused and took out the book "A Thousand Magical Herbs and Mushrooms".

"The answer is hidden in this, has anyone thought of it?"

Hermione looked at the book in her hand and thought for a moment, then showed a look of sudden realization and quickly raised her hand.
