Demon summoning is not a "summoning" technique—a question that Maca has known for a long time. And the so-called "demon" is actually just a code name created by a powerful wizard who specializes in soul rules in ancient times a long, long time ago, nothing more.

That's right, that was "a long, long time" ago...... Even earlier than the end of the ancient Greek era, when the goddess of death Kern and the vile Helpo were born.

"I may have been the first wizard to study those evil items, but ...... I'm just digging deeper into them by their nature. If you've studied it, you know what the source of sin is—you don't have to start with those few things to study the rules of the soul. ”

“…… And it is clear that the predecessor who created the demon summoning technique was the first to embark on this path. ”

A calm, gentle ...... And with a slightly cold female voice, it was echoing in the halls of the Great Hall of Hogwarts, speaking the words in some ancient language without any emotion.

Truth be told, although most people don't understand these words, the sound alone can even make people feel extraordinarily charming. Just listening to it makes me feel like I can draw the outline of a slender and graceful young woman in my mind.

However, it is this voice that can't help but fascinate and even sink into it, but it faintly carries a kind of cold that rejects people thousands of miles away. Listening too much often makes people involuntarily fight a cold war.

Warm and cold, two diametrically opposed temperaments, seem to be one at this moment, and people don't seem to notice any contradiction between the two.

The sense of disobedience born from this strange harmony is truly impressive.

But it wasn't long before another voice suddenly came out of the auditorium. There seemed to be a little tiredness in the tone, but it was also neither humble nor arrogant, mellow and peaceful.

"The source of evil...... Well, in fact, this question has been bothering me for a long time, and it is only recently that I have somewhat understood. Lady Kern, I'm not as gifted as you are—I'm just a little luckier than the average person. It's just that...... If I'm not mistaken, 'sin' is only half of the soul rule, right? If there are 'demons', there should be—"

"Nope."

Before the young man could finish speaking, he was interrupted by a female voice.

"I've been looking for it, it's taken a lot of time, and I can't come back. Behind that 'door', all I could see was a flawless mass of pure energy, and something like this...... Endless 'sin'. ”

When he said "like this", a large number of indescribable "black lights" suddenly cast out from the windows of the auditorium, so deep that it was like a crack in space. And in that "gap", there was a silent cry and wail, which made even the soul involuntarily begin to tremble.

"Sin can manifest, but its counterpart to another energy cannot. So the former can be used by us shamans, while the latter ...... But I can't even touch it. At the end of the day, it is impossible to fully grasp the rules of the soul. ”

"Therefore, if we cannot master the soul, we cannot become the masters of death—the three-level rule is only an unattainable existence for us who are small."

Fortunately, those dark glows were only fleeting and did not stay long. Before the words fell, the endless black light suddenly disappeared, and everything returned to its original appearance.

"Whew-"

I only heard the male voice take a long breath, which showed what kind of huge pressure the situation just now brought him.

And at this moment, I heard the female voice at first suddenly turn to say:

"Hmm...... When I came back, I seemed to see a person...... Do you know that person? It was an old man wearing a silver robe, with a pair of transparent half-moon-shaped quartz pieces on the bridge of his nose, and a white beard and white hair. ”

"Whew...... ...... male voice was still gasping softly, and she could hear her ask, and then said, "The old man with a white beard and white hair? If you say an old man, it's not strange that you have gray hair, right? I don't know. ”

"Then forget it." The female voice paused slightly, and then said lightly, "Okay, I've said enough, so what about you?" Mclean...... Are you going to give me the Seven Evil Manifestation Items, or do you want me to pick them up myself? ”

With that, the Hogwarts Great Hall fell silent again, and both sides seemed to be very patient, and neither was in a hurry for this moment.

And in the meantime, in the hideout inside Camp Weymouth, Delphi's narrative is coming to an end.

……

“…… In that misty pure white space, there is the origin of all the 'spirits' in this world. And at the end of that space, there stood a huge 'door'. ”

"I'm sorry, I can't explain it more clearly, because I've only scratched the surface myself. I just want to say that there is a certain energy that exists on the other side of that 'door' that is the essence of all the 'demons' that have come to this land today - sin. ”

At this point, Delphi finally paused slightly, giving everyone present a little room to digest the complex information.

After a few moments, she finally said:

"Sin can be broadly divided into seven branches, arrogance, jealousy, anger, laziness, greed, gluttony, and lust, which correspond to seven magical items that have existed since ancient times. In the same way, there should be a total of seven so-called 'demons' that have descended so far. ”

"Miss Granger, judging by what you described earlier, what you've encountered ...... It should be 'gluttony'. ”

It's not easy to explain these things, and Delphi can be considered to rack his brains to describe them simply, and there are inevitably a lot of confusion and mistakes in it.

After all, even she herself can't remember the "memories" in her head.

And when she finished speaking, Harry on the side couldn't help but say:

"That'...... My Gryffindor sword must be 'Anger', right? What about other than this? What ancient magic props do the other six branches correspond to? ”

"I'm sorry, Mr. Potter, but I can't tell you exactly that. Because...... There are a few items that I don't know about, and I don't even know if they've ever been found. ”

Almost all of the people who know the full answer to Harry's question have been focused on Hogwarts, as this is perhaps one of the most crucial pieces of information in the whole affair.

This is a key to unlocking "sin".
