Hogwarts starts with stealing power.

Hagrid really thought that the magnetic wand was a great help to him.

When he had no wand to use and could only use a broken one, it was the magnetic wand that helped him out of the predicament.

Things are not always smooth sailing in the Forbidden Forest, there are always many unexpected events.

With the magnetic wand, Hagrid saved himself several times. Although he felt that he could save himself without the magnetic wand, the difficulty was different.

He has a deep affection for the magnetic wand.

Lin Xia said: "Hagrid, I am not asking you to throw away the magnetic wand. This wand is a universal wand that can be used by all wizards.

But its limitations are too great. The magic wand unleashed through it can only obtain 30% of its original power.

Even if I give you a fine magic wand that can exert greater power, it is still not enough for you.

Now that you are a professor at Hogwarts, you should change your wand, if for no other reason than to be responsible to your students.

If you are short of money, I am willing to lend it to you..."

As Lin Xia spoke, Hagrid's head lowered lower and his expression changed.

What Lin Xia said before did not convince him, but the words "in order to be responsible for the students" at the end touched him deeply.

He wanted to be an excellent teacher, and if anything happened to his students in the future, he hoped that he would be able to stand up and give him protection.

This is his obsession.

If there were other professors besides Dumbledore who were willing to stand up and believe in him, perhaps he would not have been expelled.

Hagrid was silent for a moment, his tall figure seemed to be hunched over, and said:
"You're right, Lin Xia. To be responsible to my students, I should replace my wand with a good one. You don't have to lend me money. I can still handle this little thing."

Lin Xia didn't know what she was thinking of, and smiled: "Hagrid, you don't have to throw away the magnetic wand, but wear it around your waist as a decoration."

She took a few steps back, looked at the magnetic wand carefully, and said affirmatively: "At least the appearance of this wand is still very beautiful."

This magnetic wand is silver-white with some intricate patterns on it. The overall texture is very good and high-end.

Of course, this wand is also taller than ordinary wands, and is far beyond the reach of ordinary wizards.

At that time, it was made specifically for Hagrid's body shape, so it could be considered a custom-made one.

Hagrid's eyes lit up at her suggestion.

Lin Xia walked out the door and started her patrol tonight.

Tonight's patrol was still calm and there was nothing noteworthy. She looked up and out the window from time to time, and a few white shadows would flash over and quickly leave the window.

That's a Dementor.

Whenever she saw these Dementors, she felt a chill in her heart, as if she was being stared at by some cold and evil creature.

Dementors are indeed evil, and just seeing them will affect your mood.

However, with the Dementors around, they are also protecting the students' safety in disguise.

Lin Xia suddenly thought of this and stopped, frowning slightly.

Wait, with the protection of Dementors, can Hogwarts really become safer?

Why did she feel that this was more like a cage, and that the Dementors were lurking outside?
Just as this thought came to her mind, the compass of destiny in her mind suddenly turned to the "nursery rhymes" column.

[You subconsciously sense that something is wrong with Hogwarts, but no one notices the crisis, so you decide to save yourself]

[You invented a nursery rhyme. Under the subtle influence of the nursery rhyme, the defense of Hogwarts will be improved, and it will also seriously weaken the impact of the Dementors residing here.]

[Note: Even if you use nursery rhymes to change some regional characteristics, some things are inevitable]

A nursery rhyme popped up in Lin Xia's mind. This nursery rhyme was very simple and was praising the four founders of the academy.

"There are four people in Hogwarts
A Gryffindor whose bravery was called recklessness

A Slytherin whose ambitions were called mediocre

A Ravenclaw whose wisdom was called stupidity

A Hufflepuff whose ordinariness is called greatness

And they all have one thing in common, that is, they like Hogwarts~
Hogwarts, Hogwarts, their favorite home~"

The nursery rhyme flashed through Lin Xia's mind and was memorized. She recited it repeatedly and could feel that the nursery rhyme seemed to resonate faintly with Hogwarts.

With the spread of nursery rhymes, Hogwarts seems to be really protected by the four major colleges.

It's incredible.

After all, the four deans are historical figures. Could it be that even though they are dead, their spiritual wills have been protecting Hogwarts?
Lin Xia came back after patrolling and stood at the designated location to think deeply. This statement was not impossible.

The heroic spirit is immortal and the will is immortal.

There are examples in the wizarding world where spirits are projected into the material world and eventually transformed into strange creatures, such as the one that suddenly appeared in front of Lin Xia at this moment -

"The sanctimonious Lin Xia, the stupid Lin Xia, the vulgar Lin Xia, the good-for-nothing Lin Xia!"

Pipigui suddenly came up and started talking to Lin Xia, making all kinds of funny movements in an attempt to irritate her.

The angrier Lin Xia gets, hey, the happier they are!

Even Lin Xia herself couldn't figure out how she had offended Peeves.

But when Lin Xia thought that Peeves' insults to Harry were more unpleasant than those to himself, she felt a little relieved.

Lin Xia said, "Peeves, do you like to recite nursery rhymes?"

Peeves looked at each other, "What is that?"

Lin Xia: "Singing, do you like singing?"

Peeves circled around Lin Xia a few times with a sly smile on his face: "Of course we can sing~ Lin Xia is a big fool, a big fool~ Lin Xia is a big bad guy, a big bad guy~ Lin Xia is stupid, stupid~"

Lin Xia said calmly: "I heard that you are looking for some toys that can scare little wizards recently?"

Peeves suddenly choked up and stared at Lin Xia eagerly. Three Peeves came up and asked curiously:

“Can you find the toys?”

"What toys do you have?"

"Can you really scare a little wizard?"

"Are you kidding us? Why would you help us deal with the little wizard?"

Lin Xia raised the corner of her mouth imperceptibly. Peeves are not all fools, but compared with humans, these creatures are still too simple after all.

She said: "I am just sharing some toys with you. I am not asking you to deal with little wizards. If you are not interested, forget it."

It would have been better if she didn't say anything. Once she said it, it would be even more impossible for Peeves to let her leave.

"I want toys!"

"I'm going to scare the little wizards so hard that they'll pee their asses off!"

"The more afraid they are, the happier we are, ha ha ha!"

Lin Xia looked at them with deep eyes and said, "I can provide you with a batch of specially made toys, but there is a prerequisite before that. That is, you have to help me spread a song."

……

The next day, Harry came to the Great Hall for breakfast with two big dark circles under his eyes.

Others were a little worried when they saw Harry's condition, but Harry was very calm and didn't want to expose his weakness.

After dinner, he walked with Ron, but suddenly stopped, moved to Draco's side, and called him to a place.

Lin Xia, Ron and Hermione looked at Harry and Draco who were talking not far away. Hermione guessed:

"Harry accepted reality much quicker than I thought. I thought it would take him at least a week to come to us for help."

Ron touched his nose and said, "I felt that I couldn't let Harry be depressed in the dormitory, so I dragged him to the common room yesterday. We had a good chat, and finally Harry decided to go and find out the news."

Lin Xia said, "Let's go, let's go to the Defense Against the Dark Arts class first, so as not to be late for class."

Hermione was about to leave when she suddenly stopped, as if she remembered something. She immediately handed her schoolbag to Ron and hastily took out a book from it.

"I'm going to the bathroom first. Please help me carry my school bag to the classroom."

Ron took her schoolbag and felt it was heavy in his hands, as if he had taken a dozen bricks.

The straps of this backpack are a bit overwhelmed and are in a state of being half rotten and half not rotten.

He looked down and said exaggeratedly: "Arithmetic Divination, History of Magic, General Knowledge of Muggles, Advanced History of Spells...

Why does she bring so many books? Do we have so many classes in one day? I remember there is only one Defense Against the Dark Arts class today?"

Lin Xia looked at Hermione's back as she disappeared after a while, a thoughtful look flashed across her eyes.

She said, "Hermione seems to be very busy recently. Yesterday, she left the lab halfway through her work and didn't come back until half a day later."

Ron complained: "I don't know what she is busy with day after day!"

On the other side, here are Harry and Draco.

Harry stammered out his meaning, and Draco had already guessed it, so he agreed immediately: "Okay, I'll help you check it out."

Harry said unsurely, "Will your parents help?"

Draco shook his head. "There's no need to use them. I'll just ask my house-elf to check it out. Since all the Slytherin students know about it, it means that this information should be public."

Harry breathed a sigh of relief.

He had no good feelings towards Draco's parents.

In comparison, Draco was the most polite noble he had ever met, although their first meeting was not pleasant.

As for Lin Xia, he didn't sense any aristocratic airs around her, but only felt the aura of a top student who surpassed everything else.

The school bell rang, and the two people hurriedly took the magic elevator and headed to the Defense Against the Dark Arts class.

When the bell stopped ringing, they just walked into the classroom.

Professor Lupin of the Defense Against the Dark Arts class was already there, and what was more surprising was that Snape was also there.

He was wearing a black robe and had a gloomy face.

He glanced at the two people who were almost late, then looked at Neville, and finally met Professor Lupin's eyes.

"New Defense Against the Dark Arts professor, I have to give you a piece of advice, you have to be careful of a little wizard.

His name is Neville and he causes accidents in almost every class, which is worrying."

Professor Lupin said calmly, "Who is Neville?"

Neville Longbottom raised his hand tremblingly: "It's me, Professor."

He closed his eyes nervously, having accepted his fate of being driven out by the teacher.

However, Lupin said, "Okay, you will be the first one to go on stage in this class."

When these words were spoken, everyone was surprised.

Lupin looked at Snape: "Thank you for the reminder, Professor Snape, but I am confident that I can teach Neville well. Perhaps you can stay and see how I teach?"

Snape's expression grew even darker.

Lupin continued, "By the way, may I ask how Neville performs in your class? You said he causes accidents in every class, so he may not be very talented in Potions, right?"

Professor Snape walked out of the Defense Against the Dark Arts classroom with a gloomy face.

The other little wizards gathered together and whispered.

Even Hermione said: "This professor seems to have a really tough temper. He is defending his students. This is the first time I have seen a professor dare to speak to Snape like this. I like his style!"

Hermione's voice suddenly came out, startling Ron.

"Hermione, where did you come from?"

Hermione said as a matter of course: "I've always been by your side!"

Ron turned to look at Lin Xia, "Did you see it?"

Lin Xia smiled but said nothing.

"Okay, little wizard, let's get to the point. You can put your books back. This time we are going to have a practical class."

Professor Lupin put his tattered box on the podium. He looked much better than when the school started. Many young wizards already knew that he had an amazing appetite.

It is said that this professor used to be in Gryffindor College, which made the Gryffindor students secretly mutter that with the professor's appetite, he should be assigned to Hufflepuff!

The young wizard put away his textbooks and exchanged strange looks with each other.

They had had virtually no practical lessons in Defence Against the Dark Arts, and when they had, it was bound to be a disaster.

Last year, for example, Lockhart, the sanctimonious former teacher, brought a cage of pokemons to class and let them out, but even the professor couldn't deal with them.

Seeing everyone took out their wands, Lupin asked the little wizard to follow over.

They walked through an empty corridor and around a corner, finally arriving at a large classroom that looked empty.

On the ceiling in front of the classroom, there were several Peeves hanging upside down in the air, stuffing chewing gum into the keyhole.

They wiggled their toes and suddenly began to sing: "Lupin, lunatic, idiot! Lupin, lunatic, idiot..."

Suddenly, one of the peepers saw Lin Xia and pulled the other peepers.

The Peeves turned over one after another, facing the wizard, and sang another song:

"There are four people in Hogwarts
A Gryffindor whose bravery was called recklessness

A Slytherin whose ambitions were called mediocre

A Ravenclaw whose wisdom was called stupidity

A Hufflepuff whose ordinariness is called greatness

And they all have one thing in common, that is, they like Hogwarts~
Hogwarts, Hogwarts, their favorite home~"

The little wizards were all very surprised. It was rare to hear such nice nursery rhymes from Peeves' mouth.

Although some sentences are quite ironic, considering the whole, this is still a song praising the presidents of the four major colleges.

Because the melody is simple and easy, some little wizards learned to hum it after listening to Peeves singing it several times.

"There are four people in Hogwarts
One is called Gryffindor, and his bravery is called reckless..."

Lupin frowned, thinking about the nursery rhyme. (End of this chapter)
