Hogwarts starts with stealing power.

Everyone went outdoors.

Hagrid introduced the first creature to everyone at the beginning of this semester: Grindelwald.

This creature appears in "The Book of Yokai". According to the book, it is an aggressive aquatic creature of unknown level. The book does not assign a level to any of the magical creatures.

Oh, except for those particularly useless ones, they will specifically describe them as "very gentle" and "non-aggressive".

Grindelwald is pale green all over, with sharp horns on its head and green teeth. Its limbs have long, thin, and powerful fingers, but these fingers are easily broken.

In terms of size, they resemble humanoid creatures, but are relatively small.

These creatures often live in lakes, swamps, or steep ponds, and are frequently domesticated by mermaids as pets or guards.

As Hagrid led the students toward the lake, he said, “The Greendylows feed on small fish, but they like to attack Muggle and wizard children who are near the water and drag them into the water.”

Once you fall into the water, that's their domain. If you encounter a creature like a Greendylo, I hope you can get away from the water immediately and don't even think about fighting them underwater.

Their weakness is also obvious: their slender fingers, while appearing strong, are very easy to break.

Suddenly, a young wizard raised his hand and said, "In the Defense Against the Dark Arts class last semester, the professor taught us how to defend against Grindylow."

Hagrid was somewhat taken aback. He didn't know the specifics of the Defense Against the Dark Arts course, and he hadn't expected that the young wizard had already met Grindylow.

This……

Hagrid, who had been speaking eloquently, appeared somewhat flustered and uneasy.

Lin Xia took the initiative to say, "Defense Against the Dark Arts teaches us how to defend against Grindelwald, but Magical Creatures teaches us to understand the habits of this creature. The two should not be confused."

Being able to resist doesn't equate to sufficient understanding; only through deep understanding can one quickly seize their weaknesses.

Hermione reacted quickly, replying, "Yes, if Professor Hagrid hadn't said that these creatures would be tamed by mermaids as pets, I wouldn't have known that mermaids had such strange tastes."

Although Grindylow doesn't look ugly, he's not good-looking either. In the little wizard's imagination, mermaids are extremely beautiful creatures.

But their domesticated pets are so ugly... perhaps even the mermaids we imagine aren't this beautiful.

With Lin Xia and Hermione helping each other, Hagrid relaxed a little and continued to explain the creature to everyone.

Although many young wizards were seeing this creature for the first time, their training in Defense Against the Dark Arts involved confining Grindylow in a narrow water tank, so the wizards were not afraid.

But this time they went to a lake, a deep lake, where many Greendylo were hidden.

Hagrid, concerned for the young wizard's safety, didn't have them all crowd around to check, but instead stood some distance away from the lake.

Hagrid instructed the young wizards to observe the deep green lake, saying mysteriously, "If you listen carefully, you will notice something unusual on the lake."

Do you see those tiny air bubbles?

Some of the bubbles are Grindelwalds breathing; they hide their breath within the bubbles blown by the fish. If you know enough about them, you can determine their location and the number of Grindelwalds by looking at the bubbles on the lake's surface.

When the young wizards heard Hagrid say that, they all stared wide-eyed at the lake.

Everyone acted like they knew everything.

But Lin Xia knew that these young wizards didn't understand anything, and when Hagrid couldn't see them, they were asking each other what others had discovered.

"Have you seen Grindelwald?"

"No, I didn't even see any bubbles."

"I didn't see any either. Isn't the lake very calm? Where did Professor Hagrid see the bubbles?"

Suddenly, a little wizard exclaimed excitedly, "I see a fish!"

However, no sooner had he finished speaking than a strange noise suddenly arose on the lake.

A Greendylo suddenly leaped out of the lake and jumped toward the little wizard who was speaking, stretching out its slender hand to try to catch him.

Fortunately, the little wizard was some distance from the lake, so Greendylow only jumped in mid-air before falling back into the lake.

But this scene terrified all the young wizards!

Did you see it just now?

"No, I only saw fish, I didn't find anything else!"

"It seemed to appear suddenly, it was so well hidden. If it had remained hidden in the water, I wouldn't have noticed anything."

Lin Xia and Hermione stood to the side watching, their expressions somewhat serious.

Hermione turned to Lin Xia: "Have you noticed anything wrong?"

Lin Xia nodded: "Grindylo is classified as level xx, which means it is harmless and tame, but it is aggressive."

Once they fall into its territory, wizards are easily harmed. The magical creatures Hagrid taught in class are somewhat too difficult for the young wizards now.

Hermione said seriously, "Yes, Magical Creatures class is different from Defense Against the Dark Arts class. The former is about understanding, while the latter is about resistance."

The former requires close contact with magical creatures, while Defense Against the Dark Arts only requires training on specific weaknesses. In that atmosphere where everyone is fighting, my courage also increases.

But if I'm just asked to observe, I'll become complacent and might very well be dragged into the water by Greendylow.

Lin Xia, as if thinking of something, asked, "Hermione, do you know the book 'The Monster Book of Monsters'?"

Hermione: "I know, isn't this the textbook we use for our Magical Creatures class?"

Lin Xia raised an eyebrow: "It seems you haven't really delved into this book, 'The Monster Book of Monsters,' which mainly focuses on the research and classification of dangerous creatures.

These creatures are still too dangerous for young wizards. I felt it wasn't a good idea from the beginning, but Hagrid didn't bring out any particularly dangerous magical creatures last semester, so I didn't say anything.

But starting this semester, the young wizard met Grindelwald in the very first class, and from then on, he only encountered increasingly dangerous magical creatures.

I think it's necessary to remind Hagrid to adjust the magical creatures based on the young wizard's abilities. What do you think?

Hermione frowned at first, then relaxed and nodded, saying, "That's what I think too."

Hermione was thinking, "So this monster book is so dangerous. No wonder I couldn't find it in the school library before."

Perhaps it is precisely because books are dangerous and not easily discovered that the library did not put these books on the shelves.

In the first lesson of the new semester, Hagrid simply had the young wizard stand outside the lake and observe Grindelwald, without instructing him to do anything else.

After class, Hagrid assigned a paper, requiring the young wizard to write about his impressions of seeing Grindelwald, in at least 500 words.

The young wizards let out a chorus of groans. Whatever the subject, writing papers was their least favorite thing.

After the young wizards dispersed, Lin Xia and Hermione approached Hagrid and expressed their concerns.

Hagrid, however, felt that none of this was a problem.

“Grindylo is safe. As long as you don’t get dragged into the water, you can easily be knocked down on land. Even if you are dragged into the water, there are other ways to break free.”

This semester, I want to teach the young wizards how to fight Grindelwald in the water. After they understand Grindelwald, I plan to have them learn about mermaids.

Lin Xia and Hermione exchanged a glance, both feeling that Hagrid was taking it too lightly.

Indeed, in Hagrid's eyes, even a ferocious dragon like the Norwegian Spinosaurus was a cute little thing.

Lin Xia said, "Hagrid, you overestimated the students' ability to cope."

Since last semester, our "Fantastic Creatures Conservation" class has involved safety risks, which is why we insist that you learn to wear armor for protection, whether for yourself or for your classmates, to ensure everyone's safety.

Hermione said, "But Hagrid, what you're teaching is getting more and more dangerous. If you're going to teach according to the creatures in the monster book, you'll have to have a safety officer in the classroom."

Hagrid was taken aback: "Safety officer? No, safety officers are only assigned during flight lessons. There's no danger at all in magical creatures class, so why would we need a safety officer?"

Lin Xia sighed helplessly: "Hagrid, you have to understand, you are different from us."

You like magical creatures, and you can even raise a grumpy dragon like your son, but you can't do that with a young wizard. You even want to teach him how to observe mermaids. Mermaids are such temperamental creatures; once you anger them, they won't care if you're a Hogwarts student.

Lin Xia was worried that Hagrid's decision to have his students observe mermaids would anger the race.

Other students may not know, but doesn't she know?

Mermaids are not beautiful at all; on the contrary, they are ugly, have bad tempers, and their aesthetic sense is different from that of ordinary people.

Hagrid stammered, "I'll think about it. I've learned how to wear armor, so if we encounter any danger, I can save the students."

Lin Xia: "You can save one, but you can't save two or three."

Hermione suggested bluntly, "Hagrid, why don't you change the textbook for the Magical Creatures Protection class? 'The Monster Book of Monsters' is too dangerous for students. You can choose something gentler."

After entering the third grade, students will be introduced to the class on the protection of magical creatures.

Haiger succeeded the previous professor who had retired and resigned. He had left behind a lot of teaching experience and achievements, including the textbooks he used in class.

Hagrid just felt that the knowledge in these textbooks was too outdated and not interesting to learn.

He also thought "The Book of Monsters" was very promising and interesting, which is why he decided to choose it as the textbook for the Magical Creatures Conservation class.

Hagrid made the request at several faculty meetings in order to have the book used as a teaching material, but it was rejected many times.

The school had finally gotten his approval, and now they wanted him to switch back to the normal textbooks, which Hagrid was extremely unwilling to do.

He immediately shook his head and said, "No, we must use this textbook. It will allow the young wizard to learn more."

At the same time, he patted his chest forcefully and said confidently:
"Don't worry, I'm quite skilled at using armor now, I can definitely protect the little wizard!"

Seeing this, Lin Xia and Hermione remained silent for the time being.

At lunchtime in the Great Hall, Draco asked them why they went to see Hagrid, and the two expressed their concerns.

Draco had been exposed to many magical creatures since childhood, but he felt nothing about them.

Whether it was a difficult situation or something that required observation of the mermaids, he always found a way to deal with it.

However, young wizards like Neville, Ron, and Harry, who don't often see magical creatures, were somewhat bewildered.

They had no idea how dangerous mermaids were.

Besides the mermaids, they also had no recollection of the creatures they would later learn about, which were even more powerful than mermaids.

Mikel listened quietly from the side, but did say a fair word in Hagrid's defense.

"In fact, the previous professor's course on the protection of magical creatures also included many magical creatures with high levels of danger in the textbook."

However, Hagrid is different from his previous professor, who only had his students memorize the habits of those dangerous magical creatures without putting them into practice.

Hagrid was quite insightful; he not only wanted us to read the book, but also to understand what this magical creature was like in real life and to observe it thoroughly.

I think Hagrid is a practical person. If he chose more realistic magical creatures and his arms weren't so aggressive, I would really enjoy his classes.

Ron also said, "The Magical Creatures Protection class is quite interesting. Although I don't know how it was taught before, I find it very interesting to be taught by Hagrid. I can learn about many unique creatures."

Neville also raised his hand: "Yes, that's how I feel too!"

Since learning that the Magical Creatures Protection class would allow students to see many amazing creatures, almost no students have skipped the class, and everyone listens very attentively.

Lin Xia thought for a moment and said, "Then let's try our best to persuade Hagrid to hire a security officer. In case something really happens, he'll have someone to help him."

After lunch, there were no classes in the afternoon.

Lin Xia, Hermione, and Draco continued to spend time in the lab.

They need to start preparing for the project they're going to do.

The Weasley twins also arrived at the laboratory, where they used the public laboratory equipment to develop further ideas about the potion of inspiration.

The twins believed that if they were given another week, they could finish the potion!

Thinking about it this way, the two of them became very excited.

This was the first time they had ever done an experiment so smoothly!

They had inexhaustible materials, excellent experimental conditions, and no one to interfere with their ideas.

If it weren't for the fact that they had to attend classes every day, the twins would love to spend all their time in the lab.

Watching the results gradually come to life in their hands, they felt it was an amazing feeling!
And the other side.

Ron and the others returned to their dormitory, and under Harry's supervision, Ron continued setting up the tracking rune array with a bitter face.

Ron gripped his mithril pen tighter, glanced at Harry, and whispered, "Harry, how about I draw it again tomorrow? I still feel a little unskilled."

Harry said with a serious face, "Ron, you'd better start drawing today, otherwise you'll be punished again if Lin Xia asks about it tonight." (End of this chapter)
