The Magical Principles of Natural Philosophy at Hogwarts

Five minutes later, Gilderoy Lockhart was sitting alone in his messy office, his face uncertain.

He was threatened by a student. Although the other student's request was very simple, just asking him to buy some illegal drugs on his behalf, Lockhart knew that this was just the beginning. Once the other student had a handle on him, he would only make more and more excessive demands.

, their appetite will never be satisfied.

If you don't want to let it dominate you, you must think of a countermeasure.

On the other side, Erwin and Melanie were on their way back to Gryffindor Tower.

"You are much more skilled than I thought." Melanie looked at Erwin, "Have you often done this kind of thing before?"

"I think your experience in deceiving men's feelings is amazing." Erwin smiled back.

"Using one's gender is a woman's privilege. I can only say that most men are too stupid." Melanie curled her lips.

"Huh." Erwin said hesitantly.

The fire in the common room is burning brightly, and this big fireplace has not been extinguished since October. Not far away, Harry, Ron and Hermione are talking about something, and there is a thick book spread out on the table in front of them.

.

Erwin's eyesight is very good now, so he can see the words and illustrations on the pages of the book clearly.

That seems...not a book that second graders can read.

Most of the books in the restricted area of ​​Hogwarts are subject to strong or weak magical restrictions, and the triggers are basically magic texts. In the first grade, Erwin was helpless with most of the restrictions, but now he has mastered them.

A lot.

He secretly pointed his wand at the book and said silently in his mind, "Ansiz - Karnaz - Belcano."

As if a restless soul was suddenly injected into it, the book suddenly floated up and shook violently. With quick eyesight and quick hands, Harry rushed over and pressed the book down on the table with all his strength.

Ron was quite confused, "What's going on?"

"I don't know," Harry said with difficulty; "Oh, my God, the words are disappearing."

On the page he was holding, the originally densely packed letters were quickly fading away, and would soon turn into pure paper. At the same time, the book itself was struggling more and more fiercely.

Ron was also panicked and immediately went up to help Harry. The first response to a problem was to use physical force to solve the problem. This is one of the signs of a wizard's immaturity. However, Ron still did the right thing, "Think of a way, Hermione."

!" he shouted.

Miss Nutria was staring at Erwin. It seemed that she had already noticed his presence and what he had done. "This joke is not funny, Erwin," she said coldly.

"Are you so sure it's me?" Erwin spread his hands to show his innocence, but he still stopped activating the restriction.

Harry and Ron breathed a sigh of relief when they saw the words on the book reappearing.

"You have to show off your magic level like this?" Hermione was still unhappy.

"I apologize." Erwin admitted his mistake very succinctly, and then changed the subject, "But compared to my little prank, your behavior of secretly stealing banned books... seems to be more serious, right?" He smiled half-heartedly.

.

Both Harry and Ron couldn't help showing guilty expressions.

Hermione could barely maintain her composure, "We are allowed."

"Who gave permission?" Erwin asked, "Which professor thinks that second-year students are qualified to read books of the level of "Powerful Potion"?"

"Professor Lockhart." Hermione's face looked a little unnatural.

"Aha, you found him to be a very useful person, right?" Erwin smiled meaningfully.

"Wait a minute," Hermione reacted at this time, "how do you know that is "Power Potion"?"

There was scrutiny in her brown eyes.

"That's because..." Erwin leaned into Hermione's ear, which caught the little girl off guard and made her face turn slightly red.

"Actually, I have read this book more than once." Erwin lowered his voice, but allowed Harry and Ron to hear clearly.

The two boys looked at him with a very strange look.

"What?" Erwin shrugged, "You also know that I often go out at night just like you. Do I always go to the kitchen to find food?"

"That's true of George and Fred." Honest Ron said.

Erwin took the initiative to reveal a secret, and he obviously felt that Harry was much closer to him.

"So, would you mind telling me which potion you are going to brew?" Erwin asked.

The two little boys looked at Hermione.

Miss Nutria hesitated for a moment, but finally decided that Erwin was trustworthy, "Polyjuice Potion." She said: "Draco Malfoy seems to know about the Chamber of Secrets, so we plan to pretend to be someone close to him,

Then get some information."

Erwin smiled, "So you still hate that guy."

To have this kind of thought shows that these three people have developed obvious hostility towards Malfoy.

"Don't you remember what he called us then?" Hermione's body trembled slightly with anger, "Mudblood..."

"Of course I remember." Erwin said softly: "But since you think a certain person is an ignorant fool, there is no need to be affected by him emotionally, right? The angrier you are, the more proud he will be,"

Hermione was stunned, "Then how should I react?" She was a little confused.

After all, she is just a twelve-year-old girl, living alone in this huge school away from her parents.

"Ignore him, treat him as a barking dog, and then determine whether the dog has fangs. In short, don't let your emotions affect your reason."

At this moment, Erwin suddenly realized that he had neglected Hermione's physical and mental growth to a certain extent before, which was considered a dereliction of duty. After all, he was her "elder".

"So, you want us to return the book?" Harry asked hesitantly.

"Go back? Of course not," Erwin shook his head, "You seem to have made a mistake. In fact, I support you."

He is not a professor at Hogwarts, so he does not need to consider whether students should study step by step. As long as they take precautions, there is no danger in brewing polyjuice potion. Since they want to do it, let them

If they do it, it will be a good experience process. Even if they don't succeed, their potion level will definitely improve.

Raw materials are not a problem at all. There is no need to take risks and steal the school's inventory. Now Gold Galleons is no longer a problem for Erwin, and through Lockhart's name, most of the medicinal materials can be obtained.

Can be purchased.

His confident expression and calm demeanor were so contagious that Hermione nodded involuntarily.

Back in the dormitory, Erwin listened to Neville tell a lot about the mandrakes planted by Professor Sprout.

"They will be fully mature in a few months. Professor Sprout is really amazing. Every plant has survived. You must know that juvenile mandrakes have a mortality rate of nearly 50%..."

Erwin was mainly listening, but he didn't show any impatience. Neville soon became sleepy, said good night and fell asleep.

This child has a simple mind and sleeps very well.

It was late at night, and the moon was almost invisible tonight, so it was extremely dark. Erwin suddenly felt a hot feeling coming from his pocket. It was a rune stone sensor. He had fiddled with a lot of small things like this before, two by two and one by one.

Yes, they can sense each other and can be used to transmit a simple message.

The other corresponding rune stone is on Melanie's side and was activated by her, which means that Ginny Weasley is taking action again.

Ron was suspicious of Malfoy and never thought that the problem would arise with his sister.

Erwin got out of bed quietly, put on his cloak, and saw Melanie at the door of the Gryffindor lounge. The two looked at each other and nodded slightly.

Erwin used the Disappearance Charm, and although Melanie had little strength left, she still had a simple and effective way to hide her whereabouts. When they left the lounge, the Fat Lady shouted in horror: "Who is it?"

?Why can’t I see you?”

Her screams were erased by the silent spell Erwin had prepared in advance.

Erwin and Melanie followed Ginny, and just like last time, she was unaware of their presence.

She still held the black-covered diary tightly in her hand.

But this time she did not go to the bathroom on the second floor. Instead, she continued down the stairs to the first floor and pulled a secret wrench behind a witch statue.

With a low rumble, a dark secret passage appeared, and Ginny walked in without hesitation.

She stopped halfway, faced a wall, and hissed like a snake.

A new passage opens, which is a downward staircase.

The stairs were very long, and Erwin, who was following Ginny, estimated that they had reached at least fifty meters underground. Ginny stopped at this time and opened a door in Parseltongue again.

This time, they came to a wide underground space.

Two rows of snake-shaped statues stand on both sides. There is a luminous stone for lighting in the snake's mouth, and at the end is a wall with a huge human face carved on the wall. It is the face of an old wizard, and the eyes have no pupils.

Ginny walked straight up to the face, paused, and continued hissing, but this time the wall didn't turn into a portal.

A hollow appeared at the mouth of the face, a rustling sound came from inside, and something was sliding inside.

For no apparent reason, an aura of fear enveloped this underground space.

Ginny turned her head, her delicate facial features showing a distorted state.

"Come on, there's no need to hide!" She said, her voice filled with resentment and hatred, "Aren't you coveting my secret? I'll show it to you now, you humble bastard!"
