The Magical Principles of Natural Philosophy at Hogwarts

Percy responded to Erwin two days later.

"Mom said you can't ask for your money. That car has nothing to do with our family. You don't need to ask for our advice if you want to do anything with it."

Mrs. Weasley's original words in the letter were: let that car go to hell.

"That's your property, are you sure you'll just abandon it like this? You don't need to ask Mr. Weasley's opinion?" Erwin confirmed repeatedly.

"Don't worry about Dad's opinion." Ron was a little downcast. His new wand seemed hopeless. "He can't resist Mommy's will. Mom has hated that car for a long time, and she just wants to find a reason to throw it away."

Erwin has a certain understanding of the distribution of power within the Weasley family.

"I can understand Mom." Percy said to Erwin: "You are only in the second grade after all, this deal will be like the Weasley family cheating you of money, and speaking out will affect our family's reputation..."

Erwin could understand that money-related matters could easily touch a sensitive line of dignity for a hard-pressed family.

He originally wanted to use a little money to establish a preliminary courtesy relationship with this magical family that seemed to have a long heritage, but it seems that this plan cannot be realized for the time being.

After all, Ron was a teenager at heart, and soon he stopped thinking about the five hundred Galleons. "Are you really so interested in my car?" He was very interested.

"That is, I have had a fantasy car since I was a child." Erwin said casually.

"Can you really just take out five hundred Galleons?" Percy's doubts were elsewhere. "Your family allows you to use such a large sum of money?"

"Actually...it's not a lot of money." Erwin shrugged. "It's [-] pounds, which can buy about... a third of a Muggle car?"

Ron looked rather strange, and began to wonder if his family's overall property was enough to buy a Muggle car.

Percy shook his head helplessly, "Even if you ask Hagrid to help you capture my father's magic car, you must abide by the law of secrecy, and it's best not to use it in front of Muggles."

"Of course I will pay attention to it."

Erwin thought for a while, and suddenly his expression changed, "I think Mr. Weasley must have paid a lot of money to build such a car, and I will definitely pay the five hundred Galleons, since your parents don't seem to be very willing, Then the money can be paid directly to you.”

"For us?" Ron opened his mouth in disbelief.

"No," Percy refused without hesitation, "we can't take your money." There was something strange in his eyes.

"Don't worry, listen to me." Erwin didn't rush, "These five hundred Galleons are obtained from selling your father's wisdom crystallization, which is a regular income, and it is also a kind of respect for your father's labor achievements. As members of the Weasley family, you also have the right to keep such a property. Just imagine, when your family is in serious financial difficulties one day in the future, you took out the five hundred Galleons... you Will be the hero of the family."

Just as Ron was about to say something, Percy preempted him, "Although what you said is indeed reasonable, it is impossible for us to accept this money behind our mother's back. Stop talking, Erwin."

Ron could only shut his mouth resentfully.

Erwin looked indifferent, "If you change your mind, you can come to me to withdraw money at any time."

For the next few days, until Halloween, Erwin's words kept echoing in Ron's ears like demon whispers, making him turn and turn even at night, making it difficult to sleep.

He never thought about what would happen if he had a lot of money, and Erwin planted a thought in his heart.

This is not a fortune that can be ignored. Most of the income of the Weasley family comes from the salary of his father, Arthur Weasley, and five hundred Galleons require him to work for half a year.

Since my mother is not going to want that car again, she can't ignore its value. Naturally, the purpose of selling things is to get money.Erwin was right, as his father's son, he could keep the money and take it out when the family needed it urgently.

Of course, when the money is in his hands, he can use part of it for legitimate and necessary consumption, such as changing a wand, buying a new robe, and giving Harry a decent gift at Christmas. Gifts, these are all very necessary expenses, and he promises not to use another Nat for the rest of the money...

Ron's outlook on money has been profoundly improved within a few days. During class, he would often suddenly become sluggish because he thought about the money, which made Snape find an opportunity to deduct a lot from Gryffindor. Less points.

Finally, on the morning of Halloween, he couldn't hold back and found Erwin in a sneaky way.Offer to "keep" that money.

However, Erwin's expression was very strange, "You came a step late."

"C-Are you late?" Ron was dumbfounded.

"That's right, Percy already asked for the money the day before yesterday."

The young Weasley kid's complexion changed several times, and the faint sense of guilt disappeared in an instant. A kind of anger of being deceived and betrayed was brewing in his chest, and he immediately rushed to find Perry. Master Xixing went to inquire about the crime.

Looking at Ron's back, Erwin's mouth curved slightly.

"Is this Mr. Erwin Frost?" A weak voice came suddenly.

There was no one around, Erwin looked around and determined the source of the sound, which was the portrait in the corner.

The portrait is a timid little woman, "Mr. Frost, Principal Dumbledore wants you to go to the principal's office now."

Erwin nodded slightly, "Understood, thank you."

The little woman bowed slightly to him.

Using these portraits with a certain amount of intelligence can allow specific messages to be quickly transmitted within the school. Erwin is not very surprised.

After more than half a month, Professor Dumbledore finally returned to Hogwarts.

Without being asked to say any password, Erwin stepped onto the spiral staircase behind the huge gargoyle statue, and he entered the principal's office ten seconds later.

Nothing in the office has changed, the portraits of past principals are still noisy, and there is a beautiful scarlet bird on the bird stand in the corner, it is a phoenix.

Dumbledore's phoenix partner, Fox, Erwin naturally knew about it, and had a chance with it when he came to the principal's office last time.

Unlike the legendary divine bird that can control flames, real phoenixes are not very aggressive. They have strong magic power, and their tail feathers can be used as the conductive material for the core of the wand, but their abilities seem to be limited to healing and regeneration.

Dumbledore appeared, and he followed Erwin's gaze, "That's Fox." He introduced.

"In the future, if I have a chance, I will raise a little fox and call it Phoenix." Erwin chuckled.

"Not a bad joke," Dumbledore said solemnly, but without airs.

"Has the matter behind Master Flamel been dealt with?" Erwin asked.

Dumbledore nodded slowly, "Things are going well, just enough to allow me to come back to the Halloween dinner. Erwin, I hope you can understand that I have concealed your existence from the outside world. Wait until you can be alone. It would be more appropriate to announce that you have accepted the inheritance."

Of course Erwin would not have any objections, it is a very simple truth to make a fortune silently.

It is rare to meet the strongest wizard in Britain. Of course, Erwin will not waste this opportunity. He uttered all the questions he has accumulated during this period of time, including spells, spells, potions, and everything else. have.

Dumbledore answered one by one.

Time passed unknowingly, and when Erwin solved all his doubts, he had a feeling of enlightenment. Although he was used to self-study, having expert guidance would definitely improve his learning efficiency significantly.

At the same time, he also realized the gap between himself and a truly powerful wizard.

He still has a long way to go, magic power is only the cornerstone, and all structures on it must be supported by knowledge and will.

"Time really flies by." Dumbledore looked at the wall clock that was pointing to twelve o'clock.

But Erwin didn't look like he was going to say goodbye.

Dumbledore smiled, "It seems that you still have doubts."

Erwin nodded dully, "I don't quite understand... your treatment of Melanie."

"Do you think it's an unreasonable arrangement for me to put such a dangerous existence among the students?"

"A little bit." Erwin was very refreshing.

Dumbledore was not angry either, "It's really my fault, I didn't make it clear to you in advance. You should still remember how this Miss Dracula was injured?"

Erwin nodded.

"The second layer of subspace in the Wyrmrest Sanctuary essentially provides an astonishingly powerful permanent deformation effect, which allows your dragon form to be forcibly transformed into a primitive dragon, and for non-dragon creatures, the effect is Extremely deadly."

"Fatal? Could it be that Melanie was already dying when she left Wyrmrest Sanctuary?" Erwin frowned.

"Yes, every cell in her body has suffered irreversible trauma. You should already know the source of vampire magic. Such an injury means that her strength has fallen off a cliff, and it is almost permanent. What's worse is , her body still has a tendency to collapse."

"So she can only turn to you." Erwin understood.

The current Melanie is just a toothless tiger.

"We finally reached a deal. I will provide her with shelter, so that she will not become the prey of other vampires because of her great strength. Cannibalism is really commonplace for this race." Dumbledore paused For a moment, "As for the mane shackles on her body, although it greatly limits her strength, it is essentially protecting her, because it also prevents her body from collapsing."

"So that means that you even saved her, and her life can be said to be completely in your hands." Erwin understood why the female vampire was always trying to please him these days, " But since she relies entirely on you and Hogwarts, how can she make a deal? As the other party to the deal, what can she offer?"

"This requires you to discover it." Dumbledore's tone was very meaningful.

"Me?" Erwin was surprised.

"The blood magic of vampires is unique to some extent. You have already grafted blood. She should be able to help you use your blood more effectively."

"That's it." Erwin pondered, "Is the core command of the rune shackles on Melanie's body 'Natxize of Destiny'?"

"You have already found it?" Dumbledore was amazed, "Although I said this is the 'trigger' I left on purpose, I thought it would take you two or three years to find out. It seems that your research and study on runes The progress has far exceeded my expectations.”

He was relieved.

This made Erwin rarely feel that his vanity was satisfied, which was affirmed by the principal after all. "Since I found the trigger, which set of rune shackles can be controlled by me?"

"Of course, I originally planned to let you take responsibility for her. I suggest that you add an extra layer of identity authentication to that rune program, just use...your own blood, this should be the safest."
