Chapter 664 The So-called Ancient Magic
Dumbledore talked a lot, and it was obvious that these secrets had been hidden in his mind for a long time.

"The Apocalypse War lasted for a very long time, but in the end, the wizards and the church joined forces to control the four most powerful Apocalypses and killed most of the Dementors, but the sacrifice was huge."

"After the Apocalypse, the church, which was at its peak and dominated the entire Muggle world, not only lost its main combat power, but also lost control over Muggles. They were unable to continue to lead the trial of wizards, nor were they able to guide the polluted emotions to arm themselves."

"Many wizard bloodlines were cut off, and Hogwarts even suspended classes for a time. Most importantly, the Muggles' hostility towards wizards became more and more serious."

Dumbledore spread his hands. "Under such circumstances, the Church and the International Confederation of Wizards at the time, of course, did not have many members at the time, but the whole of Europe was included. Anyway, everyone chose to compromise when they could no longer fight, and the Statute of Wizarding Secrecy and the new decree of the Church came into being."

"So, to put it simply, it was the negative emotions and resentment that gave rise to the so-called Apocalypse and Dementors, and they wreaked havoc for three hundred years, killing a large number of wizards and church personnel. After a huge sacrifice, Apocalypse was killed, and the wizards and the church chose to isolate themselves?"

After listening to Dumbledore's story, Andrew made a brief summary.

The Church gave up on guiding the Muggle Inquisition wizards to gather weapons for special attacks against wizards, and chose to hide its power and stand in the open. The wizards gave up their public identities and honors, hid in the dark, and continued to retain their power to cast spells.

The so-called Statute of Secrecy is to prevent the reappearance of wizards on a large scale again, which would cause them to be hated by a large number of Muggles and lead to an apocalypse judgment like the Black Death.

"I thought the fat monk didn't look that weak. So that's why. Emotional magic is not only effective on wizards, but also on Muggles!"

After Dumbledore revealed the answer, Andrew instantly understood the importance of the Statute of Secrecy - no wonder it had to be kept secret, he had no way to verify the wizard's sacrifice, but the church that could make emperors of various countries kneel down and apologize at that time was real, and its situation was only slightly better than that of the royal family now.

"So the Department of Mysteries is used to seal that memory?"

Andrew looked at the jar of brains, but ultimately he decided not to read the memories about death and plague - he already knew the answer.

"Yes and no. Wizards are also exploring other aspects, but the most important thing is to block the painful past. Having power that ordinary Muggles cannot have will probably naturally be envied and hated. Can you imagine, Taylor, when a wizard appears in a Muggle family, what will the other children think?"

"Even brothers would feel lost, because there are too many families quarreling because of uneven distribution." Andrew shook his head. "There is no way. The Statute of Secrecy is indeed very suitable. As long as the existence of wizards is known, the resentment will always exist."

"I'm glad you think so," Dumbledore nodded, "but unfortunately, my friend can't see through it. He can't read the history of magic, so naturally he can't come here."

Is that friend of yours Grindelwald, Headmaster?

Andrew was very curious, but the brain block reminded him not to commit suicide.

"Read History of Magic?"

"Yes, you must have read the history of magic thoroughly. This is the most basic condition for hearing those stories here. In order to seal those powers and memories, the wizards used the most magnificent spell in the history of the entire wizarding world and mobilized the determination and emotions of the entire wizarding world. If you can't see through the power of the curse and can't understand the distorted history of magic, then you won't be able to understand it anyway."

Not even Grindelwald?
"But, Professor, your previous arrangement was for me to come after I finished the exam..."

"At that time I just wanted to try, maybe you have great ideas and can break the curse, but I didn't expect that your talent in the history of magic is so high that you can see through those disguises."

Dumbledore shook his head. "Do you want to take a look at the ancient magic and those sealed rituals? Although most of them can neither be used nor studied, perhaps you can pick up something that has not been affected."

Who has time to do archaeology? I am a progressive, professor. Andrew thought, but his hands tapped the glass jar honestly, following Dumbledore's description to attract the memories that sealed the ancient magic.

"Also, I'm curious," Dumbledore said with a serious expression, "If the theory is correct, then after we leave the Earth and enter the starry sky, we may be able to get rid of that restriction and truly revive ancient magic - after all, there is no curse suppressing us there, and there are no restrictions of the Statute of Secrecy."

"If so, maybe we can quickly set up a few survival circles?"

Andrew pointed his wand at the identified brain and began to read the thoughts.

Noisy, sharp, and fuzzy - a large number of fragments of thoughts and noise mixed together to form this not-so-pleasant memory.

Fortunately, Dumbledore did not make a mistake. Although most of the things in his memory were obscured by the fog, Andrew still managed to identify a magic that he had just learned not long ago.

Patronus Charm.

"The Patronus Charm is also an emotion spell? Yes, that's right, an emotion spell, but it was just too positive, so it was not blocked successfully?"

Andrew looked around in confusion, but found nothing. The sacred law of secrecy deceived wizards all over the world, but also protected wizards all over the world.

"In 1340, the Black Death broke out... At that time..."

Andrew wanted to explore more, but was bounced out. A strong emotional impact caused him to interrupt his exploration and use brain occlusion to protect himself.

"Don't have any random thoughts. There are too many wizards guarding the Statute of Secrecy."

"Yes, I understand, Professor."

Andrew took a deep breath. "That's it, Professor. I understand now. Even after graduation, I will not rashly propose the idea of ​​loosening the confidentiality law. A disaster like the Apocalypse will not happen again in my hands."

He now completely understood Dumbledore's ideas - although they were a bit exaggerated and boastful, for at least the next ten years, he would be able to represent the most advanced technological research direction in the British wizarding world, and would also be able to have the greatest influence on the graduates of the next ten years.

In this situation, Dumbledore's best option was to let him try it and see the consequences.

"But what does it have to do with me? The confidentiality law can still control things in the sky. Wait until I go to the moon and build a base!"

Andrew took a final look at the secret-sealed brain over there and said, "I think I've made up my mind, Principal. Let's go."

"Let's go then."

Dumbledore nodded.
