The Magical Principles of Natural Philosophy at Hogwarts

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

Erwin himself cannot return 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 will even appoint commissioners for this purpose. This is not some kind of discrimination, but because of relative

Muggle wizards are more likely to cause trouble than children from wizarding families.

However, this kind of attention is limited to the little wizards themselves. The Ministry of Magic is not MI6, and they have no interest in ordinary people.

Having said that, Erwin is still quite suspicious of the administrative capabilities of the Ministry of Magic. After all, judging from what he deliberately caused last time, the so-called Ministry of Magic is more like a fire brigade running around, and various emergencies are enough.

They are busy, but after all, it is better for them to be 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 the spells and gestures, they should have a certain effect, but the more important thing may be to make the wizard believe

The magic he releases can produce corresponding effects.

After all, it is written in the preface of "Standard Spells" that casting a spell without a spell is the beginning, which means that the wizard has complete control over a spell.

The basic lighting spell can release a brief dazzling bright light in Erwin's hand, and the cutting spell is even more magical. With Erwin's magic power, this elementary spell can actually extend an invisible area of ​​five centimeters.

The blade has a faint blue light on the edge, and its sharpness has been upgraded from a paper knife to that of an ordinary kitchen knife.

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

Erwin completely agrees with this. Counting the fire spell, he now has the potential to become the best barbecue chef in the world.

However, he was unable to extend the invisible blade formed by the cutting spell by another half, indicating that its length may depend on his magic power. Having said that, he had rummaged through the basic textbooks he bought before, but could not find an answer to the wizard's magic power or strength.

It is a specific standard for accurately rating the total amount of magic power. It seems that the research on this aspect is still blank.

Except for the two wizard qualification examinations in the fifth and seventh years of Hogwarts, there are no formal assessments for all wizards in the British wizarding world.

Will I eventually define the strength standard of magic power and determine the basic unit of magic power? Then use my last name to name this basic unit, just like Newton, Watt, Joule...

The little wizard who has just set foot in the magical world has the ambition to reach the top of academic circles.

Around one o'clock in the afternoon, the phone rang. It was Felwood.

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

Erwin immediately became energetic, "About that liquid?"

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

"Drink?" Erwin was stunned.

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

"Yes, he asked for it. He said it felt very similar to some high-end potion he drank before."

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

"He said it was very good and he could feel very full of magic power. Dr. Coleman checked him out, and guess what? The fractures in this guy's arms are almost healed."

Felwood was very interested, "The doctor's jaw almost dropped, and he immediately gave his assistant a drop."

"Then what?"

"The unfortunate young man has already been sent to the emergency room due to acute sepsis."

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

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

Half an hour later, a mail truck slowly passed the door and left a package. Felwood was smart and used this least noticeable method of delivery.

Erwin took the package into the house, opened the three-layered paper shell, and took out the glass bottle. The viscous liquid inside was less, with only about three milliliters left.

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

Stir it well, Erwin takes a sip, and then frowns slightly.

It seems...a little change?

His heart suddenly crossed, and he drank half the cup in one go. A few seconds later, he could really feel the full feeling of magic that Dipu had mentioned. This feeling was like boiling liquid gushing from his heart.

To the limbs and bones.

He has consumed a lot of magic power before, and now it has indeed been replenished.

Subconsciously using the Enhanced Cutting Technique again, Erwin discovered that the extended invisible blade had actually grown two centimeters longer, which meant that not only his magic power had been replenished, but even the output power had been enhanced.

He immediately drank the remaining water, and the invisible blade actually lengthened by another two inches. It did not return to its original length until the feeling of fullness completely disappeared.

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

Erwin cast a few more flash spells, and then ran around the house twice to make sure that there were no negative effects or sequelae after drinking the drop of liquid.

He dialed the Frost Manor phone number again, "Let Dipper talk to me."

After a period of noise, Dipper's voice came. His tone was brisk. It was obvious that he had been living a good life these past few days.

"Isn't it common for this kind of substance to heal wounds and replenish and enhance magic power at the same time?"

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

Something of this level?”

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

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

"I negotiated the price for an old woman who bought dragon liver in Diagon Alley, and then she gave me this glass bottle as a thank you. I thought she might have given me the wrong thing." Erwin said without blinking.

He lied, "By the way, don't forget to modify the memory of Dr. Kuhlman and his assistants about you after you recover from your injury."

He hung up the phone.

Interestingly, it seems that most wizards know nothing about the secrets hidden in gold galleons. This is not surprising. Normal people generally do not have the imagination to use aqua regia to dissolve real gold coins. El

Wen even suspected that few British wizards knew that gold could be dissolved.

After a while, he dialed again, "Professor Stewart, I have to ask you to come back." He said in a deep voice: "Prepare a larger box. I want you to put one thousand... no, two thousand galleons, two thousand galleons."

Take it to the laboratory for dissolution and extraction."

…

Time flies, and in a blink of an eye it is already September 1st.

Erwin packed his suitcase and brought everything he could possibly need, occupying about one-third of the suitcase's capacity.

There are more than six hundred galleons left in the cash box. At the rate he is spending money, he may be penniless in half a year. He must find a way to make money as soon as possible.

The storage compartment at the bottom was padded with four layers of flannel and contained a small glass vessel filled with a bottle of glimmering viscous solution. 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 shouted from downstairs.

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

Erwin actually didn't understand why he had to take a train to go to a magic school. Maybe it was to facilitate the gathering management?

Carrying the suitcase downstairs, I picked up the cage of Sabi the Eagle Owl. This guy was so big that the cage containing it was quite heavy, and Erwin couldn't even lift it.

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

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

Mr. Granger came over from Manchester yesterday. He drove them to King's Cross Station. The group passed through the crowded crowd and came to the place where the ticket was written, between platform nine and platform ten.

"Platform nine and three-quarters," Erwin mused, looking at the wall between the two platforms, "Why not nine-and-a-half?"

When I arrived, I happened to see a black-haired boy and a red-haired boy pushing a cart into the wall. Very good, Erwin and Hermione just had to do the same.

Hermione was saying goodbye to her parents. The parting was sentimental, because this was probably the first time Hermione had been away from her parents for a long time, and she would not be able to see her parents again until the Christmas holidays. Mrs. Granger's eyes were red and she gave her daughter a hug.

.

On the other side, Erwin was chatting in a low voice with Professor Stewart, "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 their parents, even if

Really not, Sabi should also remember where home is."

The eagle owl responded with a loud call in its cage.

The ticket clearly advised ordinary people not to enter platform nine and three-quarters, so the Grangers and Professor Stewart had no choice but to stop here. Erwin saw that Hermione was a little uneasy, so he stepped forward and walked towards the platform.

Go to the wall.

He passed through the wall without touching anything. It was obviously just a simple illusion. Now in front of him was an old-fashioned train painted in black and red. The platform sign 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, and she looked around. She saw a strange environment and strange people. No one paid attention to their arrival. Her parents were behind her, but they seemed to be a world away. A strong sense of loneliness suddenly surged.

Miss Shanghai was so worried that she subconsciously leaned towards Erwin.

Erwin didn't understand Hermione's emotions at all. He walked straight to the locomotive with purpose, circled it twice, and even entered the cab to take a look.

"It turned out to be a real steam train, and the fuel was still coal. It must have a history of at least 150 years." Erwin found it quite interesting, "Let me guess, it should be more than a hundred years ago.

Did the Ministry of Magic or Hogwarts manage 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

Didn’t it have any impact here?”

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

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