The Magical Principles of Natural Philosophy at Hogwarts

This time Dumbledore designed the teleportation area with Erwin as the center, so the boy returned to Hogwarts alone.

As for the principal himself, he has to deal with the funeral affairs of Mr. and Mrs. Flamel.

Erwin felt that as Master Flamel's last apprentice, he should have some responsibility, but Dumbledore had no intention of taking him to France.

Also, the dual identities of the original wizard and the apprentice that Flamel suddenly recruited before his death have reached the point where they must be kept secret.

So now Erwin is on top of the tallest tower of the castle, overlooking the panoramic view of the campus.

He looked at the floor tiles under his feet and suddenly realized that he had overlooked an issue. This issue he had not noticed when he returned to the castle with Dumbledore last time because he was focused on other aspects, that is, Hogwarts does not ban phantoms.

Disapparation and Apparition?

When Professor McGonagall sent him home, he had to walk to Hogsmeade before he could disapparate.

Dumbledore has teleported Erwin directly to the top of Hogwarts twice.

This shows that there are at least two possibilities. Dumbledore may have used teleportation magic that is more advanced than Apparition and is more difficult to counter, or that as the principal, he has special rights in this school.

And this special right is obviously not just because of the principal's status.

In any case, the long-lost campus life is about to begin again. After nearly three months of hard study day and night, Hogwarts, which is only equivalent to the progress of middle school education, is no different from a resort in Erwin's eyes.

As the only magic school in the UK, Hogwarts is open to young wizards of all different classes, skin colors, talents, and intelligence levels. It naturally provides more basic education.

Erwin walked towards the stairs, and the suitcase equipped with the following function automatically followed him.

After getting off the tower, Erwin saw two red-haired guys muttering something to Peeves in the corner. Birds of a feather flock together, and needless to say, they were also twin brothers from the Weasley family.

"Hey!" Erwin shouted.

George and Fred were startled, turned their heads warily, and then looked a little more relaxed, "Is it Erwin? Are you back? Long time no see."

"Long time no see." Erwin nodded.

"It's little Frost!" Peeves chuckled strangely, "Did you drink the enlargement potion? You've grown so fast."

Due to the growth and development of puberty and drinking the potion provided by Flamel for a month, Erwin was a full fifteen centimeters taller than before.

"Um..." Brother Weasley's words flickered, "We were just chatting with Peeves about some prank techniques, and we definitely didn't say we were going to do any bad things together..."

"I didn't hear anything." Erwin understood immediately, "I just wanted to say hello to you. What's the password for the rest room?"

"Whip cream," George said.

Erwin first returned to Gryffindor Tower and put his suitcase back in the dormitory. There was no one in the dormitory, and Neville and the others were still in class.

There were some new faces in the lounge, freshmen who were admitted this year. They didn't know Erwin, and Erwin didn't pay much attention to these little kids.

In the corner of the lounge, a red-haired girl seemed to be in a daze. In her hand was a black-covered diary.

Erwin hurriedly walked towards the Forbidden Forest. As he walked, the effects of the Four Stealth Spells covered his whole body, making him seem to be invisible.

The bad boy's secret base is still there, and you can see the traces left by the newly brewed potion. It seems that Neville still comes here from time to time.

Erwin kept walking and finally came to the depths of the Forbidden Forest, the camp where Norberta was previously raised.

This place has been abandoned, the tents must have been taken away by Hagrid, and weeds have covered the ground.

Erwin took a look and found that the area of ​​the open space was still not big enough, and some more surrounding trees had to be cleared. He was now quite full of magic power. He held the wand in one hand and released an invisible blade to cut down the trees, while the other hand guided the kinetic energy to impart

The ability to avoid cutting off trees from falling down on themselves while stacking them together.

The work efficiency is very high, and it's almost done in less than half an hour.

Erwin had a small cube in his hand. Half a day ago, he saw with his own eyes that a small house collapsed into such a small thing. Now he wanted to reverse the process.

Making sure the cube was locked in his mind, Erwin threw it out and waved his wand...

"Expand!"

The cube expanded rapidly, gradually occupying a large area of ​​space. After a few dozen seconds, Flamel's cabin appeared in front of Erwin again.

This is simply a miraculous alchemical creation.

Thinking of Master Flamel, Erwin couldn't help but feel a little sad. How long would it take him to study alchemy before he could make such a product?

Putting his emotions aside, he opened the door and walked into the cabin.

"Welcome back, Master."

"You don't have to call me master, Esmeralda." Erwin felt helpless.

"The order has been received, Lord Frost."

"...You should just call me Erwin."

Erwin still lacked sufficient understanding of the legacy left to him by Master Nicol Flamel. After all, Erwin was not allowed to enter many places in the cabin when Flamel was there.

The reserves in the material room are very complete. Except for some medicinal materials that are particularly precious or have strict requirements on the storage environment, there are basically a certain amount of reserves. The alchemy room and the dispensing room each have a set of various magic tools.

A fully automatic system that can carve magic words and configure magic potions by itself.

Erwin finally understood where the potions he drank before came from. Flamel's physical condition obviously did not allow him to do these tedious tasks himself.

This is not very surprising, after all, even the sweeping brooms in this hut have certain intelligence, and all that is needed to write a certain magic code or brew a specific potion is to write a

It's just a more complex behavioral program.

Of course, whether it is carving magic codes or preparing magic potions, there is an essential step of injecting magic power from the wizard, which cannot be replaced by magic tools, which means that it is basically impossible to achieve large-scale assembly line production.

In the magical world, wizards are the fundamental productive force.

Erwin felt that if he wanted to improve his magic potion level, he should try to use the two automatic production systems as little as possible, not to mention that his magic level was far from reaching the standard. God knows how many years it would take before he could be able to maintain it.

Those magic writing tools engraved with delicate codes.

Finally, Erwin stood in front of a statue of a girl.

The statue is almost identical to the golden virtual image condensed into Esmeralda, but it has exquisite facial features and does not have a blank face like the virtual image.

This is the identity of the artificial intelligence girl.

Does the lack of facial features mean that she still has not formed an independent personality? Erwin thought while stroking the thin beard unique to young boys on his chin.

Under Esmeralda's guidance, Erwin took off the pendant from the statue's neck, which was a small rune stone.

"Through the rune stone, you can give me orders directly even if you are not in the cabin."

Erwin played with this little thing and found it quite interesting. The arrangement of the magic text codes on it didn't seem to be very complicated.

He walked out of the hut and let it collapse into a palm-sized cube again. He couldn't trust such a precious thing to be left in the Forbidden Forest, so he naturally had to take it with him.

He suddenly thought, "Esmeralda, give me some Galleons."

The cube in his hand grew slightly larger, a hole appeared in it, and several gold coins flew out and landed in Erwin's hand.

These were the change that Flamel kept in the cabin for emergencies.

It's amazing, Erwin sighed inwardly. It can also be used as a portable storage space with its own retrieval function. Can I return the suitcase that I have used for a year?

I just don’t know what the impact resistance will be like after it collapses into a cube, but Erwin is not willing to do this test now.

Feeling hungry, Erwin rushed to the castle eager to return home. In the past few months he spent with Master Flamel, he ate various packaged foods in the first half, and simply drank them directly in the second half.

Meal replacement potion, now it can be said that I really miss the pies and fried fish at Hogwarts.

When he was about to leave the Forbidden Forest, he met a tall figure head-on.

"Erwin!?" Hagrid's surprised voice came from the other side, "Did Professor Dumbledore change you back?"

"Yes." Erwin replied calmly.

It seems that the "facts" that the Hogwarts staff know are this: Erwin studied the Animagus to the extreme and turned himself into a dragon, and then it took Professor Dumbledore several months to finally

All effects of deformation are rescued and eliminated.

"You really need to learn a lesson." Hagrid shook his head helplessly, "Magic is very dangerous. Fortunately, you are lucky enough to have Professor Dumbledore to wipe your ass..."

"Professor Dumbledore is a very great wizard." Erwin said sincerely.

"I think so too." Hagrid agreed.

Erwin asked about Norbeta's situation again, and learned that it had not escaped its fate after all, and was sent to a fire dragon breeding base in Romania.

After all, it is impossible to raise dragons in the Forbidden Forest.

"I can only hope that it can grow up healthily and happily there." Hagrid was a little sad.

This request may be a bit difficult, Erwin thought to himself.

Back in the auditorium, just as dinner started, the Gryffindor students, led by the Weasley twins, gave a fairly warm welcome to Erwin's return. They were told that Erwin had undergone extra training.

activities, many people are very interested in his experience.

Erwin shrugged and said he could only keep it a secret.

Untimely people will always appear. As an enemy, Gryffindor's joy is Slytherin's pain. "Isn't this the one with zero points in all subjects?" Brother Malfoy let out a sneer from his nose, and his voice

So loud that he could hear clearly from two tables away, "Why, you haven't been expelled yet, Muggle Frost?"

Erwin started to get the food as if he didn't hear him. Even if he lost the battle with this guy, the best response was to ignore it. He stuffed a handful of chips into his mouth and glanced at the Gryffindor freshman sitting opposite...

…

Then his eyes shone with surprise, and he even forgot to chew.
