The Magical Principles of Natural Philosophy at Hogwarts

……

There wasn't much in the book that particularly surprised Erwin. The black magic recorded in it was similar in type and power to what Riddle taught him.

But Erwin soon discovered the key.

"There is actually a way to reduce evil thoughts?" Riddle was also quite surprised, so much so that he forgot about his discomfort just now.

That's right, this magic book does not contain any advanced magic skills from the Dark Lord. Instead, it records a skill that serious dark wizards will definitely sneer at.

Reduces the evil thoughts required to use black magic.

As we all know, the essence of magic is a kind of "wish comes true". To use killing and murderous black magic, you must have enough hatred and murderous intention, otherwise Avada Kedavra will also use it as a nosebleed spell.

This is why in the eyes of most people, using black magic is equivalent to being anti-human and anti-social.

But Durmstrang is teaching a very wonderful technique. Although the power of the black magic released by this method will be affected to a certain extent, it does not require the caster to have enough evil thoughts.

In this way, the problem of excessive evil thoughts caused by frequent use of black magic that distorts one's character will be greatly alleviated.

"It seems that this is the fundamental reason why Karkaroff, who was once a Death Eater, was able to receive amnesty and be allowed to teach dark magic in a regular magic school." Erwin said softly.

"Weak technique." Riddle was quite dismissive.

Erwin made no comment and closed the black-covered magic book and put it away.Although he did not gain any profound knowledge of black magic, these two blood stones were worth their weight in gold.

Karkaroff has been the principal for more than ten years. It can be speculated that this method of suppressing evil thoughts should have been promoted to a certain extent. That is to say, at least in some cases, the black magic released by suppressing evil thoughts can be used to suppress evil thoughts. is legal.

interesting.

Although the bloodstone is of no use to Erwin, it can be exchanged with others for knowledge and information.

Erwin still has two and a half tubes of blood energy in his hand, but obviously he cannot take them all out at once for the Stone Frogmen to extract and refine. That would obviously be too abnormal and would attract more attention.

It will be at least another month before the next tube can be extracted, and there seems to be no need to stay here until then.

Although I was convinced that Angela was abnormal, it was obviously a very stupid choice to pretend that I didn't know anything and take the initiative to test her.

October 31, evening.

Erwin carried a suitcase with seamless stretching and walked through the streets of Hogsmeade at a normal walking speed.

The suitcase contained the goods to be delivered to Hogwarts today, including three hundred anti-dementor torches and matching fuel. Each torch was engraved with the three letters "YLH" with flame patterns.

This is the abbreviation for Hogwarts Youth League.

On the day before Halloween, Hogwarts will allow third-year students and above to come to Hogsmeade for consumption and enjoyment, so there are many people in Hogsmeade during the day, and by this time the students have returned to school. De Village instantly became deserted.

The state of martial law has also been lifted, and there are no Dementors or Ministry of Magic Aurors to be seen.

....

The fugitive Sirius Black had been missing for three months, and the Ministry of Magic's search efforts were becoming increasingly perfunctory.

After walking for about 10 minutes, the Shrieking Shack was right in front of us. It was a remote cabin that no one seemed to care about. It had a lot of forbidden magic to prevent outsiders from entering, but most of them had expired over the years. Some of the remaining Marauder's Maps The corresponding cracking method is also recorded.

Pushing open the creaking wooden door, Erwin saw a dusty interior that might not have been occupied by anyone for half a century.

After a while, he found the trapdoor entrance of the secret passage. Erwin was about to activate the innate ability given by kinetic energy and exert an upward force on it... Then the board was suddenly pushed open, and a black piece of wood was revealed. It looks like a dog head on a bicycle seat.

Their eyes met. There was no doubt that this was a coincidence, and the air suddenly became a little solid.

Then the black dog suddenly jumped out of the tunnel and rushed towards me like a round fifteenth-century cannonball.

Erwin's reaction speed was not inferior. He immediately applied the prepared energy to the black dog, trying to make it levitate off the ground.

But nothing happened except a "ding"... it was resisted.

Erwin's face twisted slightly. This was one of the reasons why he wanted to convert his natural ability into a magic weapon.

Unable to hinder the Black Dog's actions, the Ring of Repulsion was triggered, forming a force field shield around Erwin.

Then he was knocked out and the black dog's power was incredible.

This kind of direct physical collision was still within the jurisdiction of Sir Newton. The repulsion shield was centered on Erwin himself, so he rolled out more than ten meters like a hamster in a transparent ball and collided with it. A wooden wall collapsed.

Erwin, who was a little dizzy, stood up and felt quite depressed. Actual combat was indeed the only test. He looked back and found a way to add knockback resistance to the repulsion ring. Otherwise, he might be fooled when facing high-strength enemies. The ball is kicked.

"That's an Animagus!" Riddle reminded.

"Of course I can see that!" Erwin responded angrily.

The black dog was running away in the other direction. It was obvious that it didn't want to fight. It would definitely be too late to take out the magic weapon at this time. Erwin would immediately use Disapparation to catch up.

But he hesitated immediately.

This is not an uninhabited wilderness, but in Hogsmeade. A running dog may not attract much attention, but a wizard who constantly uses Apparition to move forward is really too eye-catching.

And it's easy to connect it with the round-up that happened in Hogsmeade before.

Then...change the magic.

With a finger of the wand, a semi-virtual special mark symbol appeared on the black dog's body, and this time he was not resisted.

The Mephisto brand, which I had just learned from Riddle not long ago, has no harmful effect. Its only function is to establish a weak but easily irreversible spiritual link with the caster.

"Quite a wise choice." Riddle gave a rare compliment.

The black dog's body trembled, but his speed did not slow down, and he disappeared from Erwin's sight in a few seconds.

The direction of the escape was Hogsmeade.

It seems that as a dog, it is easier to hide in crowded places?

Erwin's expression moved slightly. He had a teleportation point in Hogsmeade, a small barn that was remote and no one noticed.

So five seconds later, he was standing on the main road of Hogsmeade again.

The perceived Mephisto brand was approaching rapidly, Erwin stood still with an expression on his face.

A few seconds later, the two sides met again.

The moment Black Dog saw Erwin, it was as if he had seen a ghost. It was hard to imagine that such a human expression could appear on a dog's face.

"You can continue to run away, or let's find a place to talk?" Erwin asked in a calm tone.
