Friday night.

Carl walked into the Defence Against the Dark Arts office with anticipation.

Professor Carlo had been waiting for him there, and to his strange surprise, Professor Quirrell wasn't there.

"Carl, then."

In the Defense Against the Dark Arts office, Professor Carlo sat behind his office and said solemnly, "You've learned a lot about the Dark Magic. ”

"Although I promise to continue to teach you about it, I will not teach you the three unforgivable spells until you become an adult." Professor Carlo insisted that "you should know what the three unforgivable spells are and what it means to use them. ”

Diamond Heart Curse, Avada Soul Curse, Imperius Curse.

Carl had naturally heard of these three unforgivable spells, and they were not the most difficult, complex, and magical of the dark arts.

But these are the three most evil spells in the wizarding world, and the use of these three spells is the most common criterion for distinguishing dark wizards from ordinary wizards.

Carl nodded in understanding.

Even if Professor Carlo really wanted to teach him these three spells, he wouldn't want to learn them.

Dark Arts is a broad concept, mostly tied to damage. But Karl wasn't interested in that.

He didn't learn the dark arts for the sake of power, and he had little interest in torturing people - otherwise Polo would have been willing to provide "better" magic.

"Good." Carl's settling down in this regard relieved Professor Carlo slightly. "Today's lesson is simple and difficult, and I will hand you a unique spell."

"This spell is very special, it is both the earliest and the greatest achievement of a wizard's study of death." Professor Carlo said solemnly, "This spell is ancient and mysterious, the gesture is very simple, but it has extremely high requirements for mana. ”

"All in all, it is an ancient magic that has gradually become a symbol of the sorcerers who fight for sublime power as people gradually forget its original meaning."

Carl felt as if he had heard of the magic, at least in some library material.

"Later, with the improvement of modern magic, the wizarding world gradually prospered, and the dark creatures died, this advanced ancient magic gradually became unpopular, and eventually became a means of distinguishing the dark wizards who really fell into darkness from ordinary wizards."

Professor Carlo's expression became more serious as he said this.

"Even if there is no basis for it, I know that many people with negative traits can use this magic, but the idea is still accepted and supported by facts."

"If it's any day, be sure to remember! Karl, if one day you feel the slightest danger when you use this magic, stop it! ”

"Stop your research, stop everything you do!! Go reflect! Go modify! Whatever you do, you have to change something! Until you can cast the spell safely! ”

"It is a projection of the soul's self, a part of your deepest true self, and it knows better than you yourself whether you have really fallen into darkness completely."

Carl already knew what this spell was.

He had seen in the history of magic, related descriptions, the invincible Andros signature magic, one of the criteria for the evaluation of high-ranking officials in the ancient Wizengamot and the Ministry of Magic.

"Now remember the spell: Expecto Patronum!"

Professor Caro's wand made a delicate circle in the air, and a large cloud of silver gas flew out of the tip of the wand.

A bulldog with thick bones and a fierce expression leaped out. It walked through the air with cheerful steps, patrolling its territory, and when it saw Professor Caro, it even ran up to him and touched Professor Caro's face affectionately.

It's as simple as that, the key is to concentrate your mind and do your best to remember a happy event. The Patronus Charm is the condensation of positive emotions in the wizard's soul, and the more pleasant the memory, the more powerful it will be. ”

Professor Carlo also seemed to be infected by the Patronus in front of him, and his already tense face softened a lot, and he stroked his Patronus charm as if it were a real pet.

Carl pulled out his wand and searched his stomach to think about his happiest memories.

He had a lot of happy times, but he didn't know if that happiness would live up to the Patronus Charm.

He raised his wand, spun it in a slight circle, and said, "Calling the gods to protect you!" ”

The wand didn't react at all.

Such a performance did not discourage Carl in the slightest, and he changed his memory again.

"Divine Guard!"

"Divine Guard!"

"Divine Guard!"

“······”

Over and over.

After nearly half an hour of trying, Carl looked at Professor Carlo with a frown.

"Why doesn't it work?"

The spell was really hard, but Carl didn't feel that for half an hour, his wand would not respond at all.

Professor Carlo raised his head, put down the notebook in his hand, thought for a moment and said, "There are two possibilities. ”

Karl listened quietly to Professor Caro's analysis.

"Most likely, you're not choosing the material well enough." "You don't want it to be simple modern magic, well, according to my research, Carl, it's a ritual." ”

"You choose the best sacrifice and sacrifice to the 'god' within you, and when that god is satisfied, it will respond to your request and come to the present world."

"The theory here is complicated, and when you learn it, we'll start with it and let you know why this spell is what I call 'the earliest and greatest study of death.'"

"All in all, you have to choose the most enjoyable memory for you."

The most pleasant memory for him?

Carl really didn't know.

Not because there are too few such memories, on the contrary, there are too many such memories.

He spends every day happily with his parents, and every day with his friends is just as happy.

"I tried." "But the wand still didn't respond. ”

"No, no, no, Carl. Your pleasure may be real, but your inner spirit is not satisfied with such pleasure, and you need deeper, more intense remembrance of pleasure. ”

Professor Carlo hesitated for a moment, then said, "I can talk about my experience, but it doesn't necessarily apply to you. When I first learned this spell, I used memories from the first time I used it successfully. ”

"At that time, my life was very smooth, I had just graduated with excellent grades, and I had a lot of career development, I should say that I also had an unforgettable time at Hogwarts, but those memories were not enough to become a 'sacrifice', and in the end, it was the initial 'joy' that helped me."

"Later, it was the birth of my nephews and nieces, the Caro family had a descendant, and our family tree could be written for another generation, and this pride and joy filled my chest, and I also used a more powerful Patronus Charm."

The first "joy" and family?

Karl fell into deep thought.
