"Tom, the person you confide in has changed, I'm not like Ginny Weis, if I don't get anything useful, I'll just ruin you."

Karn picked up the quill and wrote this sentence in his journal, and it wasn't long before a line appeared in the journal, but a hint of grievance could be felt in this reply.

I will help you, it is my duty, and I have been given a mission when I was created to help everyone who gets me. ’

"What is the principle of memory magic? What are the cursed black arts? What is the spell that makes a wizard fly...."

Karn didn't go around the bush, and wrote down in his journal a lot of magic he didn't currently understand, many of which were anti-dark magic, but the flying magic that the Death Eaters used to do the most was the one he loved.

Dumbledore and the Order of the Phoenix seemed to do the same, but Lupin didn't teach him, so Karn had to focus on Tom.

The Death Eaters used their flying magic to catch up with the Firebolts, reaching speeds of up to 240 kilometers per hour, and so convenient that they didn't seem to have seen any drawbacks.

After Karn had written down a bunch of questions, replies slowly appeared in his journal, and then he quickly jotted them down.

"Tom, you sinister fellow, how dare you lie to me!"

Tom, the sinister fellow, might have something to do with it, so after Karn had finished memorizing Tom's answer, he used a small burst of fire directly on his fingertips, still burning under the diary.

'No, I'm not lying to you, these answers are true, please stop!' Don't burn me anymore! ’

"Stop? You're clearly lying to me, I have to let you know the cost of cheating me, I'll let you lie again..."

Having written these words in his journal, Karn condensed a second cluster of fire, making the burning more powerful; Tom really panicked at this time, this diary was not an artifact at all, the fire was enough to cause him damage, if it wasn't for the protective spell he put on the diary, it would have turned to ashes now.

I never lied to you, and trust me, I'm a servant-like being. ’

"I'll trust you for the time being, I'll go to a dark wizard tomorrow and ask, if there's a lie... You're ready to live in a ball of dung eggs that light a fire. ”

Karn saw that it was almost burning, so he put it away, waited for him to find time to try his flying magic, and then came back and burned him again.

Tom's ability to tempt others means that he retains a lot of power, and when he recovers, he will be intermittent, and Karn will be considering sparing him for a few days, provided that Tom still has his unknown magical knowledge at that time.

After putting away Tom's diary, Karn headed for the forbidden section.

He has no class tomorrow morning, and can spend another night studying magic tonight; After making this decision, Karn himself was a little surprised, his last thing in his previous life was studying, and he didn't expect that one day he would be able to work so hard to study.

"When facing the dark wizard, what you have to do is to shoot faster than the other party, because the dark wizard has no bottom line, is not bound by the Ministry of Magic, if you can't do this, then you can only be knocked off by the other party's wand, or tortured with the Drill Heart Curse!"

Karn's philosophy and mindset towards the enemy that he had been transmitting while teaching the senior wizards had left half of the time for them to practice spells against various dark magic creatures; Of course, many were asked by Lupin, and Karn used his mastery of magic to tell them how to cast spells better.

However, since Karn's method of casting spells was almost innate, he couldn't go into such detail, and he was not as good as other experienced professors in this regard.

If it were Snape or Lupin, the teaching would be better than him, but Kahn's teaching was relatively new, and he should have been the first professor to proded his students to take the initiative.

In class, after Karn had finished speaking, a fifth-year female student raised her hand and asked, "Professor, why do we have to be so wary of dark wizards?" Don't those dangerous creatures need to be understood? ”

Karn nodded, "That's a good question, which department do you think has the largest number of people in the Ministry of Magic?" ”

"Department of Magical Law Enforcement!"

A student raised his hand and replied, this is a very simple question, the Ministry of Magic exists to protect the British wizarding community, either to deal with dark wizards or dangerous magical beasts, but the latter is obviously not as dangerous as the former, and the number of people is also checked.

There are a small number of wizards who like to travel and contact magical creatures in person, otherwise Lockhart's books would not sell so well, because most wizards have no experience of traveling everywhere, and can only find a sense of substitution from Lockhart's books.

"Wizards and magical creatures have had several large-scale battles, all of which have been victorious for wizards, and since then wizards have not only tamed these more dangerous magical creatures, but also mastered their weaknesses and written books.

But the Dark Wizard does not, and each Dark Wizard has different methods..... Franco, your shot is still too obvious, and it would be more stealthy if you could hide behind Katie's back. ”

Karn then flicked a petrification spell away, a gesture that surprised the students below, as few people had noticed Franco's move, and Franco was one of the few wizards in the senior class who had learned the art of silent spellcasting.

Unexpectedly, this was blocked by Professor Pente, and he didn't look in Franco's direction at all.

After class, Karn walked out of the Defence Against the Dark Arts classroom first, and then went straight to practice magic in the Forbidden Forest; If he walked a little slower, there was a high probability that those female students would stay behind and delay time.

It's a pity that the magical creatures in the Forbidden Forest are very honest and have no tendency to cause trouble, so Karn can only practice the Flying Spell and the Fierce Fire first, and as for the Dementor Mind, which has no spell casting target, it is not easy to practice.

The topmost floor of the Astronomy Tower.

Dumbledore stood here and saw in the distance that in the direction of the Forbidden Forest, there seemed to be a red firework flying in the clouds in the sky.

"Flying Charm, there shouldn't be this book in the Forbidden Book Zone, it seems that our Professor Pent learned this magic from someone else... Severus, do you think that looks like Fox? ”

Dumbledore pointed in that direction and asked Snape, who had just walked up.

"This magic is only for the Death Eaters and the Phoenix Society, and if you don't know, that's what the Death Eaters taught him..... And Mr. Steward is living in the forbidden area lately, Dumbledore, don't you have any ideas? ”

Snape's tone was flat, but he was still a little reluctant to let a stranger take over the role of the Defence Against the Dark Arts professor.

"It seems that Professor Pent is not only gifted in ordinary magic, but also in black magic."

Dumbledore laughed twice, he had been to the Forbidden Forest and knew that Karn was practicing fire; Thinking of the other party's ability that might have originated from the phoenix, he didn't have any other thoughts except for some surprise.

"And the Animagus, though very secretive, the smell of mandrakes is very difficult to hide."

"yes, it's like it was... Sorry, Severus, I just heard about his Transfiguration in general, but I didn't expect to learn Animagus directly. ”

Snape pursed his lips slightly, listening to Dumbledore's lame explanation, didn't he know what he had just said.

"Since you know everything, then I don't need to say more!"

Snape left the tower straight after saying this, Quirrell was possessed by Voldemort in the previous school year, and this school year there was another Defence Against the Dark Arts professor who could fly to the sky.

It was natural for Snape to be worried, but Dumbledore trusted Scamander more, and he had been in contact with Karn, who was only interested in magic and had no idea of being a pure-blood.

Even the goddaughter was a Muggle-born wizard, such a person was born to be inherently incompatible with the Death Eaters, and it was because of this that he didn't care about Karn's stay in the forbidden book area night after night, but it really scared him at first, and Dumbledore didn't expect Karn to practice fire in the book ban area, but fortunately, he was very skilled in controlling the fire.

Snape had thought a little too much about it, and Dumbledore wished he could figure it out for himself.

"Godfather, this is what the senior sister asked me to pass on to you."

Hermione arrived at Karn's office with some gift boxes, placed them on Karn's desk, and asked, "Ron, please let me ask you, is Ginny okay?" Do you need to check it out? ”

"It's okay already, she's not in a good mental state lately because she's thinking too much, you can suggest her go and see the joke collection... Who gave this gift? Why is it all garlic and onions? ”

Karn opened the gift box and choked on the smell of raw garlic, and the onion was still cut, was this a gift or was it a trick on him?

"I... I don't know, there were a lot of senior sisters who gave gifts at that time..."

Hermione's big brown eyes rolled around, but luckily Karn was frowning at the garlic and onions, otherwise he could have seen the look of guilt on Hermione's face.

"By the way, Hermione, I may be out of Hogwarts for a while in the future when class is less, and if you come to my office, don't let anyone know about it; At the other end is Diagon Alley's home, where only you and I can use it. ”

Karn pointed to the vanishing cabinet behind the curtain in the corner, and continued to Hermione, "You can't skip class, though. ”

When the greenhouse is expanded, Professor Sprout's herbal medicine class will be replenished; At that time, he had very few classes, and he could go back to Diagon Alley through the Vanishing Cabinet to negotiate a few business.

Most Keitel was given a talent by Karn, and recently signed a hefty purchase contract with many herb producing areas, which made Karn's magical material store's monopoly journey smoother.

As a result, many European families have sent letters to Keitel, hoping to sign a supply contract with Karn's magical material shop; For example, the Delacour family and the Demiller family rely on fire dragons and other magical materials for their business.

"I see, Godfather, I'll be sure to talk to you before I use it."

Hermione's eyes lit up and she replied quickly, she didn't expect there to be a handy prop.

"Godfather, if the senior sister wants to give you a gift...."

Karn said decisively to Hermione, "Tell them to prohibit this behavior, students should study hard in school!" ”
