Harry Potter’s Book of Sin

In this world, summoning is undoubtedly a real existence.

In ancient times, early wizards were inspired by nature and created regular magic and summoning.

They struggled to survive the confrontation with various powerful ancient magic races, and studied bit by bit in depth, until they dominated the entire ancient world.

But what must be said is that the so-called "summoning technique" at the time was definitely not magic that transfers something from other places to oneself.

The true summoning technique must have a medium as the core-it can be a clear water, it can be a fire, or even a stone that can be seen everywhere.

Then, what the wizard has to do is to use the rule rune he knows and conform to the core to condense a stronger force and shape it into what he wants.

Finally, he branded his will into it, and the summoning technique was completed.

This was the most primitive summoning magic that was later called "spirit summoning" by wizards, and it was also the biggest reason why wizards in ancient times won more with less.

Of course, this is also one of the reasons why Maca always believes that the predecessor of the modern transfiguration discipline is mostly ancient summoning.

However, the "devil summoning technique" initiated by Haierbo by every means has nothing to do with the ancient summoning technique in essence.Not only did it not originate from primitive summoning techniques, but it was even considered taboo by most ancient wizards because it involved some very bad things.

The reason why it is also named "Summoning Art" is actually because some of its magic theories happen to coincide with Spirit Summoning Art, and they seem to be quite similar on the surface.

For example, it also has a "core" existence as a medium——

"...And the core is the witch that Martin was willing to sacrifice for, Muriel." Under the pit he pulled out, Maca said while stretching his hand to the twist in front of him.

Based on the sighting scenes Lupin narrated before, combined with the emotions Martin expressed in the past, this conclusion is actually not difficult to draw.Obviously, the faces of those gray fog condensed from Muriel's will undoubtedly.

But the point is, where did Helbo hide Muriel?

Before discovering this circular stone slab deep underground, Maca was naturally unable to be sure, but now he had guessed some possibilities.

Yes, the mirrored space of the City of London that he had strayed into was indeed an excellent place for Tibetans.If there is no such accidental "guide" by Delphi, even if he even thinks about it, it is obvious that he will not get in.

But after this speculation, Maca couldn't help but start to be confused again-what exactly is Delphi going there?

Regarding this question, Maca's heart is not without speculation.On the contrary, he was reluctant to draw conclusions easily because of too many guessed answers.

In the final analysis, Delphi concealed too much from him.

Accompanied by the illusion that the whole body was squeezed and twisted, Maca only felt that the scene in front of him suddenly turned over, and then the color in the entire field of vision disappeared immediately.

After the space stabilized, he looked up and saw that the disk-like sky above the pothole was gray.

However, the fog that had always permeated the city of London has suddenly disappeared without a trace, replaced by an unspeakable depressive atmosphere.

When Maca saw this, he nodded silently and said in his heart:

"It really is here."

...

In order to study clearly how to activate the slate as little as possible, Maca took a lot of effort.Therefore, he still came in quite a bit later than Delphi.

And about half an hour ago, just above the pit where Maca entered, Delphi's figure suddenly appeared.

In fact, from where she appeared, she didn't dig a hole like Maca when she came in, but a round slate opened directly in the previous alley.

At this point, it really seems a bit suspicious.

"Um...coming in."

After stepping into this black-and-white space again, I saw Delphi look around first, and then pouted and nodded as if confirming that he was not in the wrong place.

After that, she didn't stay any longer, and walked out of the alleyway following the mysterious aura that was pervasive in the city.

It can be seen that this black and white city still doesn't even have the slightest vitality.Only occasionally, there will be one or two gray shadows hurriedly passing by on the empty street, and there is usually another twisted black shadow chasing behind them.

Delphine knows very well that the gray shade being chased represents a wizard or a Muggle, the former is the one that flows in gray, and the latter is the one that is almost solidified.

As for the black shadows that chase them, they are naturally the congregants whose minds are controlled by Helbo.

In the mirrored space here, the external creatures will only reflect their respective magical power contours. What kind of magical powers they have in their bodies will have corresponding manifestations in this space.

Delphi was thinking about it, and suddenly he noticed a gloomy but exceptionally strong wave of magic power suddenly coming from behind, making her look back subconsciously.

After that, she saw a distorted outline that was much larger than the black shadow she had seen before, and suddenly rushed out from the corner on the other side of the street, and ran to this side quickly.

Just as the majestic black shadow swayed like flames, the entire outline was far from the normal human posture, and it looked like a black, constantly twisting and swaying fireball.

Undoubtedly, that was the black pupil wizard she had fought before, the soul collector created by Helbo through the steps of the summoning ceremony.

Of course, at the moment Delphi is in the mirror space of London City, the other party is obviously not aware of her existence.Seeing that group of dark shadows rushed across the street silently, and suddenly went to the other end of the street.

Seeing the other party running far away, Delphi shook his head secretly, and then started walking along the street.

Not long after, she walked for a while in this black and white city, then turned a few more turns, and came to the gallery ruins where the entrance to the black market was hidden, as if naturally.

After all, this is the mirrored space of London, and the place that should be connected is obviously the same here.After entering the gallery and passing the secret passage of the fairies, Delphi finally came to the underground black market.

As soon as she entered here, she clearly felt that the depressive breath that seemed to be everywhere suddenly became stronger and stronger here.

That's right... it's here, that's right.

Delphi paused in the hall of the Dark Ling Pavilion, and went straight to the outside world.She knew that the core of the demon summoning technique...no, it should be said that the witch who was a "sacrifice" was hidden in a corner of this underground black market by Haierbo.

And to tell me where it is—at first she accompanied Pansy to the old house to find Martin and Muriel, didn’t she?

I remember that they could not find the two at the time, but now, at least it shouldn't be difficult to find Muriel.

Needless to say, Delphi's hesitations and thoughts after agreeing to accompany Pansy to the black market, it was obvious that he was already considering his current trip.

Thinking of her so resolutely returning to the present from the future, how could she be unprepared for anything?It can be said that in fact, many things are within her plan, and they are all part of her intention to achieve the ultimate goal.

It didn't take long for Pansy to turn left and right along the route he and Pansy had already walked. After more than ten minutes passed, he had already arrived near the old house.

And until this time, Maca outside had just figured out the mystery of the round slate, and was making some preparations for the idea of ​​entering this space!

"This is it."

Just standing at the doorway downstairs, Delphi could feel the strong oppressive force surrounding him, and the source of this oppressive breath was undoubtedly on the second floor of this old house.

It's just that she hadn't hesitated very much when she came along this road, but when she got here, she suddenly stopped involuntarily.

I don't know if it was the invisible oppression that made her a little uncomfortable, or some thoughts in her heart made her hesitate. Shouldn't she just go face her own life like this and become the most difficult question for Delphi.

She understood that before she reached this point, she had no retreat.The current hesitation is not only meaningless, but also a waste of time.

However, she still couldn't help feeling uneasy... well, maybe it's more than just "uneasy".

After closing her eyes for a few minutes in silence, Delphi suppressed the emotion that was lingering in her heart, and took a deep breath before opening her eyes suddenly.

Seeing her sapphire-like eyes, it was clear again.

The next moment, Delphi suddenly stretched out his hand to push the door open, and walked in with firm and decisive steps.

...

When Delphi had reached the "core" of the demon summoning technique, on the other side, Maca had just entered this obscure mirror space.

He stopped a little by the hole he dug out, looked back inside, and then jumped up and flew towards the sky above the black and white city.

It was different from Delphi, because Mondungus had already figured out the source of the fog through Muggle's memory. Maca, who knew this piece of information, didn't have to sense the breath to know where to go.

So after entering, he immediately decided to go to the entrance of the underground black market, and the speed was more than a little bit faster than the previous Delphi.

"Delph..." On the way to the gallery, Maca couldn't help but secretly said, "This time, I think you have to make it clear to me."
