"Fawkes is so cute, of course it's different."

As a Scamander, this kind of question is answered so reasonably.

Dumbledore was choked, but he was helpless, even if he had explored some of the mysteries of this castle in his fifth year, and looked at the contracts that appeared from his body, he was tired and almost chose to stay away from this castle.

Contract magic is the most stable and longest-lasting magic known in the wizarding world.

If this magic node with the highest energy level in the Scottish Highlands is the cornerstone of Hogwarts, then the contract network that extends from the nodes after decades of refinement has built the framework of the castle.

And the main vein of all contracts is derived from an ancient ritual.

However, with Aini's ability, the content of this core contract cannot be parsed yet, but some peripheral contracts can be seen clearly.

It can be said that when the pen of acceptance writes your name into the book of access, you have already begun to establish a connection with this ancient institution, and this connection will become inseparable in the rest of your study and life.

Contracts will leave their mark on every Hogwarts student - and most of this is done without the students knowing.

However, in fact, these contracts will not harm the young wizards, but will benefit them, otherwise such contracts without strict confirmation by myself will inevitably cause the subject of the contract, that is, Hogwarts, to be counterattacked.

For example, when you receive an offer and reply, a contract is formed, which does not force the young wizards to do anything, but allows them to receive a seven-year education for free, all at Hogwarts' expense.

In addition, we all know that the first wand of the little wizards only costs 7 Galleons, and the unicorn hair alone costs 10 Galleons, and the phoenix tail feathers are even more valuable, not to mention the labor cost of a master wandmaker. Most of these costs are covered by Hogwarts.

There are also materials such as potions classes and divination classes that require materials that students do not need to spend a penny, and if the course needs it, it is good to get it directly from the professor.

These are all preconditions for the contract, and Hogwarts is not without gains, but it does not ask for a return in reality, and everything acts on the mysterious world.

Aini didn't know much about this, but even that was enough to impress Dumbledore, how old is this kid now, fifteen years old? Or sixteen?

"Aini, amazing talent, it looks like you've found your way to greatness." There was a hint of joy in Dumbledore's voice, like someone walking alone in solitude.

Although there is still a huge gap between Ani and him in terms of strength, even the professors of the first echelon of Hogwarts, such as McGonagall, Flitwick, and Sinista, can now defeat him relatively easily.

But there was no doubt that the youngest professor at Hogwarts had been able to see what he had never seen at Hogwarts before. After 92 years, he once again welcomed a fellow traveler.

Dumbledore sighed in his heart, and said with a half-truthful smile, "You can be the headmaster of this school, so you are the first authority of the contract." ”

Scratching the top of Fawkes's head, Aini couldn't help but roll his eyes, Cut, this bad old man is very bad, when I can't see the black magic veins in the castle.

"Fifth." Eni was very sure that if Headmaster Dumbledore really had the first authority to this castle, he would have cleared out the xenomorph magic in Hogwarts long ago.

Before, Aini only vaguely felt that something was wrong with this castle, but after the magic perception was promoted, he easily discovered the problems in it, and some doubts in his previous life were also answered.

"No, second." Seeing Ani's doubts, Dumbledore explained: "After the establishment of Hogwarts, the Big Four all have the highest authority in the castle, but in the Hogwarts contract system, there can be no tie of permissions, and the order must be divided. ”

"The most easy-going Helga Hufflepuff took the initiative to pick up the fourth pick, and Rowena Ravenclaw got the third."

"Let me guess." Dumbledore's answer clearly raised Aini's interest, "At that time, the Big Four had not yet been divided, and Gryffindor certainly could not have preempted first authority.

After all, the castle originally belonged to Slytherin, and it had the highest authority and the most mana quota, which would make him feel that he had usurped his partner's family property, even though the castle was provided by Slytherin on his own initiative and was rebuilt by the four of them. ”

Seeing Dumbledore's affirmative bow, Aini unconsciously sped up his speech, and the feeling of clearing the fog of history with his own hands made him excited.

"It is clear that successive Headmasters of Hogwarts have inherited Gryffindor's authority. The yellow veins that were used for the Great Hall, the kitchen, the infirmary, the conservatory, and the Hufflepuff House common room clearly belonged to Hufflepuff. ”

"Ravenclaw's blue magic quota provides for some of the facilities such as the classrooms, the Ravenclaw College lounge, and the staircase in the castle."

"The defense system, the security system, the Gryffindor common room, these red veins naturally belong to Gryffindor, that is, the second authority inherited by the previous headmasters."

"As for the green veins that belong to Slytherin, most of them are located underground, and although the Slytherin House common room has to spend some extra mana to waterproof it so that no one of the bear children will break the glass, but it obviously doesn't consume that much."

"Although I haven't gone outside to check it yet, from the perspective of magic power, it is obviously related to the Forbidden Forest and the Black Lake."

Holding the phoenix in one hand, Ani tapped his breast pocket, and a bottle of Coke flew out of it and floated towards Dumbledore, "This is a specialty of the Muggle world, and it tastes very special." ”

As he spoke, the second bottle of Coke floated out, and then the cap twisted into a long straw, and Ani took a sip, finally making up for the saliva she had just consumed.

"I'm sorry Ani, I forgot to prepare pumpkin juice for you. But I have to say, what a wonderful presentation, and I can't wait to hear the follow-up. Dumbledore conjured a straw and shook the bottle to Aini.

Aini nodded and continued, "Whether it is the second authority or the third or fourth authority belonging to the principal, their respective magic veins are operating in an orderly manner, and the magic network they form is intricate but smooth and effective. ”

"In comparison, the magic network belonging to the first authority seems to be disorganized, it seems to be unmanaged all year round, and those leaked disorderly magic seem to have been transformed into a black cursed power, which is incompatible with the original magic system but is connected with each other, which reminds me of a legend I once heard."

Ani, who has read the original book, has long been sure that this is the so-called curse of the Dark Lord, and many sailors in his previous life wondered why Dumbledore's wisdom did not cancel the cursed Defense Against the Dark Arts class and teach the relevant course under a different name.

Now it seems that it is not that I don't want to, but that I can't. Without a targeted target, the accumulation of these cursed powers, God knows what the consequences will be, I am afraid it will be a disaster.

That is, since 1965, the Defence Against the Dark Arts professor at Hogwarts has become a consumable -

However, the lethality rate is not high, and most wizards who quit before completing a year in office are not worried about their lives.

After all, Discord's magic power is very small, and as I said before, contract magic is long-lasting, sophisticated, and stable, and despite thousands of years, it still operates according to the set pattern, although it is a little messy but there is no major damage.

After sorting out his thoughts, Aini selectively stated his speculations, and the inferences derived from what he "shouldn't" knew were not. With that, Aini looked at Dumbledore, waiting for his answer.

"Well, very good, I hope you always remember that a wizard's most powerful weapon is not his wand, but his mind."

"Gryffindor and Slytherin did have a huge disagreement after Hogwarts was founded, Hiccup, this drink is really strong." With a hiccup, Dumbledore took another long sip of Coke and sat down behind the table, as if to tell a long story.

Seeing this, Eni sat up and let Fawkes bounce around him, staring at Dumbledore intently.

٩(๑^o^๑)۶

If you come to reveal the secret, I won't want to kidnap your phoenix first.

"Because of recruiting students?"

"No, because of the Dark Wizard." Dumbledore denied Aini's answer.

"During the Dark Ages, both wizards and Muggles were in turmoil, with many forces competing against each other in the land, and even after the establishment of Hogwarts, there were still students killed by dark wizards."

Gryffindor advocated trying to teach them to change their ways, while Slytherin's view was uncompromising and decided to fight violence with violence. After all, Slytherin was the one who invested the most in the establishment of Hogwarts, and it can also be known from the tradition of Slytherin House that he is the most protective of the Big Four. ”

"After Gryffindor spared the two dark wizards who had hurt the students, the conflict between the two broke out completely, and the enraged Slytherin left Hogwarts in a rage, choosing to protect the campus he had built in his own way."

"Sadly, Slytherin hasn't been back since, and there are clues that seem to suggest that he died honorably against some unknown being, and that he didn't even have time to hand over his authority."

"Gryffindor regretted this, relinquished his authority and made a new contract, and every qualified headmaster would automatically inherit this authority and protect the campus."

"After taking over from Principal Dippert, I tried to adjust the mana structure of the school, as a second-level authority, I can be backward compatible with the mana quota of third- and fourth-level permissions, I sorted out the security system inside the castle, and replanned the greenhouse, but I can't make any changes to the share of first-level permissions."

"Just when I gave up trying, thinking that it would still be the same as it had been for nearly a thousand years, one of the best students returned to Hogwarts and applied for a second time to become a Defence Against the Dark Arts professor."

Aini looked down at the phoenix, hiding a hint of playfulness in her eyes, her slightly thin lips opening and closing slightly, and spit out the name from memory.

"Tom Riddle!"
