The Magical Principles of Natural Philosophy at Hogwarts

The next morning, Professor Stewart left home in a hurry after only taking a few bites of bread. He wanted to send the bottle of strange liquid to Frost Manor first.

Erwin himself couldn't go back to his original home for the time being. Dipper told him that all Muggle-born wizards are the focus of the Ministry of Magic, and even appoint a commissioner for this. This is not some kind of discrimination, but because of relative Muggle wizards are more likely to cause trouble than children from wizarding families.

But this kind of attention is only limited to the little wizard himself. The Ministry of Magic is not MI[-], and they have no interest in ordinary people.

Having said that, Erwin still has doubts about the administrative capabilities of the Ministry of Magic. After all, judging from what he deliberately provoked last time, the so-called Ministry of Magic is more like a fire brigade running around, and all kinds of emergencies are enough. They are busy, but after all, it is better to be more cautious.

Continuing to practice the spells in the book, he felt more and more that his previous feeling was correct. The fundamental elements of releasing magic are thinking, will and magic power.As for spells and gestures, they should have some effect, but more importantly, it may be to convince the wizard that the magic he releases can produce corresponding effects.

After all, "Standard Spells" is written in the preface, and casting spells without spells is the beginning, which means that wizards have complete control over a spell.

The basic lighting spell can release a dazzling light for a short time in Erwin's hands, and the performance of the cutting spell is even more miraculous. Under the strengthening of Erwin's magic power, this elementary spell can extend an invisible distance of five centimeters. There is a slight blue light around the edge, and the sharpness has also been raised from a paper cutter to a general kitchen knife.

Erwin used this to cut Mrs. Granger's steak at noon, which made her quite happy. "Magic is really convenient," she said.

Erwin couldn't agree more, and with the Ignition Charm, he now has the potential to be the best griller in the world.

However, he was unable to extend the invisible blade formed by the cutting curse by half a point, indicating that its length may depend on his magic power.Having said that, he searched through the basic textbooks he bought before, but he couldn't find a specific standard for accurately grading wizards' magic power or the total amount of magic power. It seems that the research on this aspect is still blank.

Except for the two wizard qualification exams in the fifth and seventh grades at Hogwarts, there is no formal assessment for all wizards in the British wizarding world.

Will it be up to me to define the intensity standard of magic power and determine the basic unit of magic power?Then use my last name to name this basic unit, like Newton, Watt, Joule...

A little wizard who has just set foot in the wizarding world has the ambition to reach the top of academics.

At about one o'clock in the afternoon, the phone rang, and it was Felwood.

"Good news, my dear nephew, we have made a great discovery."

Erwin perked up immediately, "About that liquid?"

"Yes, Mr. Dipper drank almost a milliliter..."

"Drink?" Erwin was dumbfounded.

This is too nonsense. You must know that there are substances that can kill people in a few micrograms in this world, and there are many types.

"Yes, he asked for it on his own initiative, saying that it feels similar to some high-level potion he drank before."

"So how is he now?" Erwin suppressed his anger.

"He said it was fine, he felt very full of magic. Dr. Coleman checked him out, and guess what? The guy's broken arms are almost healed."

Felwood was in high spirits, "The doctor's jaw almost dropped from shock, and he immediately fed a drop to his assistant."

"and then?"

"The unlucky boy has already been sent to the emergency room with acute sepsis."

Erwin was silent for a while, "You send me the rest right away."

"I knew it." Felwood on the other end of the phone smiled.

Half an hour later, a mail van slowly passed by the door, leaving behind a package. Felwood was very shrewd and used this most unobtrusive delivery method.

Erwin took the package into the house, opened the three-layered paper shell, and took out the glass bottle. There was less viscous liquid in it, only about three milliliters remained.

After thinking for a while, Erwin poured a large glass of water, then used a dropper to take a drop from the glass bottle, about a third of a milliliter, and added it to the water glass.

After stirring evenly, Erwin took a sip, then frowned slightly.

Seems like... a bit of a change?

With a heartbroken heart, he drank half of the glass in one gulp. After a few seconds, he really felt the fullness of the magic that Dipper mentioned. This feeling was like a hot liquid pouring out of his heart. To the limbs.

He had consumed a lot of mana before, and now he has indeed been replenished.

Subconsciously using the enhanced cutting technique again, Erwin found that the extended invisible blade had become two centimeters longer, which meant that not only his magic power reserve had been replenished, but the output power had also been enhanced.

He immediately gulped down the remaining water, and the invisible blade actually extended another two inches, until the feeling of fullness completely disappeared before returning to its original length.

Compared with the fireball released before, this invisible blade can more intuitively reflect the change of his magic power.

Erwin cast a few more Flash Charms, then ran around the house twice to make sure there were no negative side effects or aftereffects from drinking the drop of liquid.

He called Frost Manor again, "Let Dipper talk to me."

After a burst of noise, Dipper's voice came. His tone was brisk, and it was obvious that these few days were going well.

"Is this kind of substance that heals wounds and supplements and enhances magic power very common?"

"Common? How is it possible? A bottle of the most basic magic power replenishing potion costs fifteen Galleons, or it's just for replenishing magic power... Where did you get that bottle? The pharmacy in Diagon Alley is actually allowed to sell it. Something of this level?"

Erwin was silent for a while, "So you don't actually know this substance?"

"I can't remember it for a while, but it feels very familiar to me..."

"I negotiated the price for an old woman who bought dragon livers in Diagon Alley, and she thanked me with this glass bottle. I think she might have given the wrong thing." Erwin said without blinking. He lied, "By the way, don't forget to revise the memories of Dr. Kuhlman and his assistants about you after you recover from your injury."

He hung up the phone.

Interesting, it seems that most wizards probably don't know anything about the secrets hidden in the Galleons. This is not surprising. Normal people generally don't have whimsical ideas to use aqua regia to dissolve genuine gold coins, El Wen even suspects that few British wizards know that gold can be dissolved.

After a while, he dialed again, "Professor Stuart, I have to trouble you to come back." He said in a deep voice, "Prepare a bigger box, I want you to put a thousand... no, two thousand Galleons, put two Thousand gallons were taken to the laboratory for dissolution and extraction."

……

Time flies, and it is September [-]st in a blink of an eye.

Erwin packed his suitcase, taking up about a third of the suitcase with everything he could possibly need.

There were more than 600 galleons left in the cash box, and at his spending speed, he might be penniless in half a year, so he had to find a way to make money as soon as possible.

The bottom storage compartment was covered with four layers of velvet, and there was a small glass container filled with a bottle of viscous solution that shimmered. Due to its characteristics, Erwin temporarily Name it the Fountain of Power.

This bottle of Fountain of Power was the product of burning two thousand Galleons.

"Erwin!" Hermione called from downstairs.

It's time for them to go to King's Cross Station.

Erwin actually didn't quite understand why he had to take the train to a magic school, maybe it was for the convenience of collection management?

Go downstairs with the suitcase and pick up Saby the eagle owl's cage. This guy is so big that the cage that holds it is quite heavy, and Erwin can't even lift it.

"Would you like to have something to eat before going?" Mrs. Granger suggested.

"No mom, it's only nine o'clock." Hermione answered first.

Mr. Granger drove over from Manchester yesterday.He drove them to King's Cross Station, and the group of people walked through the crowded traffic to the place where the ticket was written, between platforms nine and ten.

"Platform nine and three-quarters," Erwin mused, looking at the wall between the two platforms, "why not one-nine-two?"

Arriving just in time to see a black-haired boy and a red-haired boy pushing a cart into a wall, well, Erwin and Hermione just need to do the same.

Hermione is saying goodbye to her parents. The parting is sentimental, because this should be the first time that Hermione has been away from her parents for a long time, and she will not be able to see her again until the Christmas holiday. Mrs. Granger's eyes were red and she gave her daughter a hug .

On the other side, Erwin was talking to Professor Stewart in a low voice, "We should still be able to keep in touch, but we can only rely on letters. The Ministry of Magic will not fail to consider the communication needs of Muggle-born students and parents, even Really not, Sabi should also remember where home is."

Horned owls responded with loud hoots in their cages.

The ticket clearly advised ordinary people not to enter platform [-] and three-quarters, so the Grangers and Professor Stewart could only stop there.Erwin saw that Hermione was a little disturbed, so he stepped forward and walked towards the wall. ?

He walked through the wall without bumping into anything, apparently it was just a simple illusion, and now in front of him was an old-fashioned train painted black and red, and the sign on the platform next to it said nine and three quarters.

It turns out that King's Cross Station has always hidden such a line.

Hermione appeared behind her, she looked around, strange environment, strange crowd, no one cared about their arrival, her parents were behind her, but it seemed a world apart.A strong sense of loneliness suddenly surged into Miss Nutria's heart, so that she subconsciously leaned towards Erwin.

Erwin didn't understand Hermione's emotions at all, he went straight to the locomotive purposefully, turned around twice, and even went into the cab to have a look.

"It turned out to be a steam train, and the fuel is still coal. It has a history of at least 150 years." Erwin found it quite interesting, "Let me guess, it should be the Ministry of Magic or Huo Gewarts managed to separate a train and a railway from King's Cross Station as a means of transportation for students, and then it has remained unchanged until now? Even if the station has been expanded several times and more advanced trains have appeared here, it has not caused any harm here. Any effect?"

From this point of view, the overall development of the wizarding society is really slow, and it seems to be a bit resistant to change.

"You guessed it." The train conductor shrugged, "But boy, if I were you, I would go back to the car to find a good seat now, and later you will have to squeeze in a small compartment with other people .”
