The Magical Principles of Natural Philosophy at Hogwarts

"That car? It belongs to the Weasleys. It's a long story." In the gamekeeper's hut, Hagrid took out some baked black cakes from the fireplace, and said this to the door-to-door visit Erwin said.

"It's a good time to try the freshly baked rock cakes. Harry and the others like this kind of snack."

Erwin took a piece and put it in his mouth, feeling the tooth challenge.

It's hard to imagine that Harry Potter and the others like this kind of thing.

"If Norberta is still there, it should like it very much." Erwin expressed his evaluation very tactfully.

Hagrid didn't hear his subtext at all, and his broad face showed nostalgia, "I don't know how the little guy is doing."

Erwin used the cutting spell to divide the rock cake into small pieces, which made it feel much better to eat. In essence, this is just a small cake with a hard skin. If you ignore the texture, the taste is actually acceptable.

The mamma's sentimentality only lasted for a short while. Hagrid grabbed a few rock cakes and put them in his big mouth, chewing them deliciously.

"What did you just say? Oh yes, that car, no doubt bewitched, is no longer an ordinary Muggle car. In early September, two little guys, Harry and Ron, drove this car to Going to school, and then unfortunately crashed into the Whomping Willow, the two little guys were fine, but the car itself stopped listening to them, and has been wandering around in the Forbidden Forest since then, Mr. Weasley seems to impose on him Some kind of amazing magic, it has a habit similar to that of a beast..."

Weasley again?Erwin's expression moved slightly, "Why do Harry and Ron take this car to school?"

"According to what they said, they couldn't get into Station Nine and Three-quarters, although they didn't find anything wrong with the station itself after the final investigation. But the main responsibility lies with the Weasleys, who failed to take good care of the two A child, and the flying car was seen by quite a few Muggles - it was all published in the Daily Prophet, and they got a decent fine."

Although he didn't know much about the situation of the Weasley family, Erwin could tell from Ron's school supplies that the financial situation of this wizard family was very tight.He had met Arthur Weasley a year ago, and it was an image of a middle-aged man about to be crushed by life and work.

"So that means the car has been wandering in the Forbidden Forest for nearly two months? Didn't the Weasleys do anything to get their property back?"

"I wish they did." Hagrid scratched the base of Hound Fang's ear. "That car is more trouble than a horned llama, and the centaurs are also very upset about it."

"Maybe we can get this under control." Erwin leaned back in his chair.

"It's hard, the horsemen are a little bit helpless..."

"I don't think it's a problem for me," Erwin said, very confidently.

Hagrid smiled, "You're only in the second grade, it's impossible..."

He stopped suddenly, because he suddenly realized that he was not a teenager who should be viewed from a conventional perspective. He was able to make rune items and help him formulate a careful dragon raising plan when he was in the first grade.

It was another young man with outstanding talents as dazzling as the sun, which brought back some bad memories of Hagrid.

But the boy in front of him is different from that person in the past after all, without that hypocritical smirk and mean arrogance.

Erwin didn't know what the half-giant in front of him was thinking. "Professor Dumbledore asked me to receive special training this summer. With my current magical strength, it shouldn't be a problem to deal with a car." He added.

As long as the headmaster is mentioned, Hagrid generally has no objection.

The gamekeeper hesitated for a while, and finally nodded, "It is not appropriate to have such an extra thing in the Forbidden Forest. I am very happy that you are willing to help, but this will not be a simple battle, but a difficult one." hunting, you have to find the car first."

"Then we need to make a plan, the kind of plan for hunting large animals." Erwin thought for a while, "If the centaur is willing to provide some help, such as driving the car into a specific area, that would be great But that's all."

"I can try to negotiate with them, but it will take time," Hager said.

After preliminarily finalizing some details of the hunting plan with the gamekeeper, Erwin left.

He returned to the open space and unfolded the Flamel Cabin. As an advanced alchemy creation, the Flamel Cabin has its own hidden function, so there is basically no need to worry about being noticed by other creatures in the Forbidden Forest.

"The potion you need has been refined." Esmeralda reported.

A row of test tubes filled with crimson liquid appeared in front of Erwin. He uncorked one of the bottles and sniffed it.

Familiar smell.

Erwin brought back a pack of dragon blood extracts from a dragon farm in Romania, which was worth nearly [-] Galleons, but selling the raw materials directly was only the most basic profit. Naturally, we can find ways to increase its added value.

It just so happened that there was such a formula in the library, the Red Dragon's Blood Potion.

This potion has a similar effect to the same dose of dragon's blood extract. It can supplement the user's magic power that can immediately participate in magic release, recover injuries to a certain extent, and can improve the user's magic talent in a very small amount.

One serving of dragon's blood extract can make ten servings of Red Dragon's Blood potion, and even if the cost of other materials is included, the profit of selling it to the pharmacy in Diagon Alley is at least [-]%.

At this time, Erwin realized how reckless it was to drink the dragon's blood extract directly before.

Of course, such a high profit rate can only be maintained within a certain amount, and exceeding market demand will inevitably lead to a sharp drop in prices.

Erwin inherited Flamel's hut, which basically means that his financial situation can be maintained in a state of abundance without much effort. How could the alchemist be short of money?

The refining process of the blood of the red dragon is quite cumbersome, but for Erwin, he only needs to complete the distribution of the magic power of the raw materials. Except for the operation that must be done by the wizard, other processes can be handed over to the magician in the potion room. The automation tool can do it by itself, and the efficiency is astonishing.

The reason why the red dragon's blood potion is called this name is not because it must use the blood of the red fire dragon, but because the scarlet grass in the raw material makes the liquid appear red.

Packing and sending this batch of red dragon's blood medicine to Diagon Alley Pharmacy, this will be Erwin's first income in the wizarding world. Gwartz's Muggle students raised funds.

In the evening, in the Gryffindor common room, Harry and Ron were worrying about their Potions paper, and Erwin sat directly next to them.

Facing the surprised gazes of the two children, Erwin looked normal, "I heard that you didn't come by train when school started. Can you tell me the details? You know, I wasn't at school at the time."

Harry didn't look like he wanted to talk about it, but Ron was intrigued, his eyes sparkling, and for the next half hour he was talking to Erwin with gusto about how he was driving his house that car, and described in great detail how it was done.

Because there were several girls beside him, especially Melanie, who was extremely handsome, Ron spoke loudly on purpose, which belonged to immature little boy's unique show off mentality.

But it wasn't just those girls who heard him speak.

"Almost, Ron." Percy couldn't help but said, "It's not a heroic story worth talking about. Have you forgotten that howling letter your mother sent you?"

Ron's face flushed slightly.

"That car has been wandering in the Forbidden Forest, and it has caused a lot of trouble to the gamekeeper Hagrid's work. It belongs to your family's property, and I think you should have an obligation to deal with it." Erwin said: "Even if you Parents can't get away, at least they should ask someone to do it for them."

"Mum would never pay for help." Percy shook her head. "In fact, she wished the car never existed."

I can understand Mrs. Weasley's mood. If Irwin remembers correctly, Mr. Arthur Weasley works in the Department of Misuse of Muggle Substances, and his main duty is to deal with accidents caused by wizards applying magic to Muggle items. , and there is such a magical car in his family, which is a typical example of knowing the law and breaking the law.

"In this case, I have a good proposal." Erwin pondered for a while, "Since your mother doesn't plan to take that car anymore, why not sell it to me, as for the price... How about two hundred Galleons? "

Percy froze, and Ron opened his mouth in surprise.

"Not enough?" Erwin seemed to have misunderstood their reaction, "Then three hundred? Four hundred? Five hundred? Only five hundred Galleons, no more!" He tried his best to show the posture of being taken advantage of.

Ron was already out of breath.

The older Percy was much calmer, "Why did you buy that car? And where did you get so much money?"

"Just out of curiosity; the five hundred Galleons all came from the exchange at Gringotts with Muggle coins; if you have doubts about the validity of the transaction, I can ask Professor Dumbledore as a guarantee; I need you to deliver it, and I will ask Hagrid to capture that car after I get the ownership." Erwin spoke quickly.

Percy was speechless for a moment, as if he really had nothing to ask.

He looked at Ron, and found that his young brother looked very excited. Looking at his wand, it was almost completely broken and wrapped with tape.

It was Percy's old wand, which Ron had been using since breaking it early in term.

Although it is a bit shameful, their family's financial situation is indeed quite embarrassing.Although [-] Galleons was not a lot, it could help my mother solve many problems, especially since my father had just been fined by the Ministry of Magic.

For a split second, Percy was about to say yes.

His expression changed a few times, "I'm going to ask my mother's opinion." He finally said.

"Understandable, my conditions remain the same." Erwin nodded.
