The Magical Principles of Natural Philosophy at Hogwarts

"This way, this way!" Melanie raised her little hand at the door of the library to greet her.

Malfoy coughed lightly, maintaining his reserve, he suddenly felt that it was really wonderful to have such a perfect girlfriend.

She deserved to be named Malfoy.

They found a seat and sat down. Melanie took a lot of books and looked like she was looking for information, which made Brother Yan even less suspicious.

But the problem was that she seemed to be too excited and spoke a little louder, so that the two of them were directly driven out of the library by the stern Mrs. Pince.

"Take the book and go somewhere else to read!"

"Sorry." Melanie was very embarrassed.

Brother Yan is very personable, or he just thinks he is very personable, "That's fine, we shouldn't be in the same room with those mediocre people, should we?"

At Melanie's suggestion, they found an unoccupied classroom nearby. It was Saturday morning and not many people would bother them here.

Melanie spread out her notebook with a look of eagerness to listen, while Brother Yan began to tell the glorious deeds of his ancestors in a rather proud tone.

After all, it is a wizarding family with a long history. Before the bloodline is diluted, there are still many outstanding figures.

During the narration, Brother Yan spared no effort to describe how stupid and incompetent Muggles are.

Melanie asked about the current situation of the Malfoy family, so Brother Yan began to talk about his father. In the son's heart, his father was always great.

"I don't seem to understand, so let's just summarize it directly. Does your father, Mr. Lucius, have any outstanding research results in magic, potions, and runes?" Melanie asked.

"Uh, it seems not." Brother Yan was a little embarrassed.

"Then did he make any outstanding contributions to the British wizarding world?"

"..." Brother Yan's face became stiff.

"So, does he have any outstanding records? Like defeating a powerful wizard or a magical animal?"

Brother Yan was silent. He really wanted to refute, but he couldn't find an excuse for a while, "My father is very famous, he is friends with the Minister of Magic..."

That was all he could say, but the words seemed feeble and ridiculous.

At this time, a sneer came.

It wasn't from Melanie. Brother Yan was taken aback for a moment and turned around.

Then I saw an unexpected scene, on the empty chair, an illusory figure gradually emerged and condensed into a solid body.

Who else is it not Erwin?He had been by their side all the time, just invisible!

"It's you!" Brother Yan was frightened and angry, he turned his head suddenly, and found that the charming smile on Melanie's face had disappeared, and there was mockery in her eyes.

Brother Yan immediately understood that he had been fooled, "You guys are in collusion?!"

I thought about shaming Erwin once, and ended up becoming a clown myself!

Malfoy's face contorted.

"Don't get too excited, I just want to surprise you." Erwin said in a teasing tone, "Go on!"

A sealed test tube flew towards Malfoy, and Melanie retreated to the wall like a shadow, but Brother Yan couldn't dodge in time. The test tube was very fragile, and it burst suddenly before it touched him. A lot of silver gray dust.

Brother Yan made a strange cry with unknown meaning. After the dust touched his skin, he felt extremely itchy and accompanied by a tingling sensation. Even a person with a strong will like steel could not bear it.

To make matters worse, a lot of dust seeped in through the gaps in the clothes.

Brother Yan was bouncing around like a monkey. Obviously, he could no longer care about the decency and glory of pure blood at this time. He quickly took off his coat and shirt, wiped off the dust on his hands, and then Throwing the clothes away vigorously.

Erwin stretched out two fingers and tapped lightly, and the clothes stopped in mid-air. It was too easy to apply the force to make them hover.

With a snap, three short house-elves, apparently Apparated, appeared right under the clothes, the cookie and pancake pan, and the one they grabbed by the arm, stuck in the middle Dobby.

Dobby is still in chains, preventing him from using magic.

Brother Yan's coat fell slowly, and it just covered Dobby's head.

The silver dust that made Brother Yan extremely itchy turned out to be ineffective against the house-elves. The cookie and pancake pan loosened their grip on Dobby, and Dobby took off his coat with trembling hands.

"The young master... gave Dobby... clothes..."

"Dobby?!! Why are you here?!" The classmate Yan Ge, who was cleaning his body in a very inconspicuous way, looked at his elf in disbelief, "What nonsense are you talking about, how can this be my fault? Your clothes??"

However, Dobby's big eyes were already filled with tears, and he held up Malfoy's coat, "Dobby is free!"

"Shut up! You idiot!" Malfoy felt like he was going crazy, and if Dad knew he lost the family elf... the consequences would be unimaginable.

Dobby had a disgusted expression on his wrinkled face, "You are the one who should shut up! You are no longer Dobby's master, you can't talk to Dobby like this again!"

Brother Yan was dumbfounded.

Erwin was also paying attention to Dobby at this time, and to his surprise, when Dobby got the clothes, he didn't feel the fluctuation of magic power.

It's not like some kind of curse has been removed, or some kind of contract has been lifted.

The freedom Dobby gained was more like... a kind of self-knowledge?

Dobby's level of magical power is among the best among his kind. Maybe he can get rid of the shackles of the house-elves long ago. After all, he could take advantage of the loopholes in the rules and report to Harry privately. It is very likely that this is what he lacks. The perception of identity, the perception of freedom.

In any case, he did not need to serve the Malfoys anymore.

The plan was successful.

Brother Yan gave up. He looked at Erwin and Melanie with a cold look in his eyes, "This is your purpose? You are finished. From now on, you will be the enemies of the Malfoy family. I will remember Stay with you, my father will not let you have a good time..."

"It's really a terrible threat." Erwin shrugged, and suddenly aimed his wand at Malfoy's head.

Brother Yan's face turned pale with fright, but he couldn't hold his breath after all, and panicked, "What are you going to do?"

He wanted to find his wand, but suddenly found that it had been thrown out with his clothes attached.

"Since I'm already an enemy of the Malfoy family, can I go too far?" Erwin deliberately teased him.

Yan Ge's classmate suddenly became extremely pale. He realized his mistake and shouldn't threaten the other party in this situation.

Erwin felt a little bored, this kid was a little smart, but he was really tender.

"Forget nothing!" he uttered the incantation.
