On the 30th of July, Polo returned to his home with Carl.

Although he had only been out for a few days, Karl was quite satisfied with Polo's teachings.

Polo not only helped him erase the troubling things like traces, but also handed over the illusion and related improved magic to Karl.

It's a pity that Carl is still not very skilled, and he can't use it as easily as Polo.

There are also three unforgivable spells, which Polo taught Carl without any burden, but he did not explain in detail how they work on the soul to produce an effect.

After Carl asks the question, Polo insists that it's an extra part, and if Carl wants to know, he can do it - at an additional cost.

He was very appreciative of the three spells, especially the Drill Heart Charm.

"But you have to remember that excessive use can damage the soul, and broken souls will not sell for a good price."

Through some of Polo's words, Carl felt that Professor Carlo's research on these three spells might be in the right direction, which also made Carl completely let go of his burden and study these three spells carefully.

It's a pity that, because of his age, Carl's three spells are only usable, and they are fine against some ordinary animals, but they are not as powerful as "Except Your Weapon" against adult wizards.

Polo also deliberately gave Carl a rather unpopular spell.

Spiritualism.

According to Polo, this spell was acquired by him in Eastern Europe and was originally a séance spell that allowed the spell caster to gain the talent to summon souls, memories, and even some abilities.

Polo improved the spell a bit, retaining the original effect, and from then on, all the souls killed by Karl could be attached to the wand with a spiritualist charm.

If the original spiritualism spell was to call for personal help, then the current spiritualism spell is to trick a person into working long hours.

These souls can not only be used as a boost to Cal, but also slightly increase the effect of Cal's use of evil spells, reducing Karl's consumption.

According to Polo, an average wand can only hold one soul. And when his wand has this soul, Carl can cast a spell at this age that can kill the average adult wizard, and if it is a good soul, then no matter what spell, his power will become greater.

Polo suggested that Karl could well consider putting aside some unnecessary "prejudices" and giving it a try.

Killing a wizard can take his talent and memory, which means that if Carl wants to, he can use this magic to learn all kinds of magic easily, and no longer have to rack his brains to find someone to teach him.

Besides, he has a lot of good things here, and Carl can also consider selling the past souls to Polo when he replaces them with new ones in the future.

"All you need is you torture them a little bit before you kill them, and fill them with pain, it's very simple, a ruthless heart mantra will do, and you know, I'm not particularly picky."

Polo said it lightly, but Karl listened to it disgustingly.

In the end, he only killed a large serpent during Polo's "teaching", and incorporated the soul into his wand.

After that, he found it much easier to use black magic, but it really didn't increase in power.

This made Carl even more vigilant.

He knew that this was Polo tempting himself: if the soul of an ordinary animal was like this, what about a man? What about wizards? What about the famous wizards? And ······ What about Dumbledore, Grindelwald's?

After a simple lure failed to achieve his goal, Polo decided to sprinkle some bait on himself.

I've already eaten the bait, but I really won't take the bait?

Carl left his home with such confusion.

He received a notice from Hogwarts to purchase third-year textbooks, just as he was planning to check out Professor Carlo's legacy and the "gifts" from the Selwyns.

The Leaky Cauldron Bar is still the same: shabby.

Carl walked in and glanced at it, business in the store was not very good, only a few people were drinking in the corner.

It was his second time here, and last year he had gone straight to Diagon Alley through the Weasley's fireplace.

The owner of the bar took one look at him and smiled at him.

He seems to remember himself? Carl didn't know, but he smiled and nodded.

Soon, Carl walked to the small patio behind the bar, and as he took out his wand and prepared to cast a spell, a voice came from behind him.

"Is this a Hogwarts student too?"

Carl turned his head, and the barkeeper came over with a family of three, all dressed in Muggle clothes like him.

Walking in the middle was a little girl with thick brown hair who seemed very curious about everything.

"Yes." Tom smiled at Carl again, he seemed to remember Carl, "Long time no see." ”

"Long time no see, Tom." Carl asked, "You brought new Hogwarts students?" ”

He remembered what Dumbledore had said when he brought him in.

Tom was about to speak, when the adults on the side interrupted with a smile: "You too, uh, are they talking about Muggle-born wizards?" Studying at Hogwarts? ”

Karl nodded: "Wizards in England all study at Hogwarts, which is the only school recognized by the Ministry of Magic. ”

"Well, how's this school going?" The lady next to him couldn't help but speak, "That lady named McGonagall said a lot, but when I thought about going to school for seven years, it was still a boarding ······"

She couldn't help but grab her daughter's hand, her face full of worry and reluctance.

Carl wanted to say that it was a good school, but then he thought about some of the Hogwarts professors and what might happen in the future, and said vaguely: "If it is to study magic, I don't think there is a better place to do it than Hogwarts, our teachers are excellent." ”

Even Snape, Karl had to admit that after removing his bad attitude and despicable character, there was really nothing to say about his business level.

"But how do you get a job after graduating from magic school?" The lady was dazed, "Could it be that you are taking a crystal ball to tell someone's fortune?" ”

Carl was stunned, he really hadn't thought about what the wizard would do when he graduated.

It's too early for him to get a job!

"Those who study well will enter the Ministry of Magic." Karl racked his brains and thought for a while, and said, "The Ministry of Magic is the government of wizards, and the head is the Minister of Magic, and it must also be elected. ”

"Do wizards want elections too?" The man asked with great interest, "Do they also have any party and shout election slogans?" ”

Carl really didn't know. However, from what Carl has seen and heard, even if there is no party on the surface, they have a similar organization behind the scenes.

Wasn't Fudge "chosen" in this way?

As for the election slogans, Karl really knows two.

One is the Umno Party, led by Grindelwald, whose slogan is "For the greater good", which Carl had just shaken over a week ago.

The other is the Death Eaters led by Lord Voldemort, whose slogan is "Magic is might".

Well, looking at it this way, the partisans of the wizarding world are not a good thing.

Tom seemed to have the same opinion, and at the mention of the party, his face immediately changed, and he coughed, and took out his wand: "If you want to talk, you can go in and talk again, I have to go back to the store." ”

Karl playfully stepped out of the way.

Tom walked over to the wall and tapped his wand against it three times.

After the brick shook and began to move, eventually forming a hole, he smiled at the little girl and said:

"Welcome to Diagon Alley."
