Looking at the Slytherin statue that was constantly swallowing the magic but not flowing back at all, only intermittently surging a little curse power, Aini's brow furrowed more and more, and he felt that he had overlooked something.

Judging from the layout of the hall, most of the functions here have been semi-closed for thousands of years, and will only be turned on step by step when triggered.

For example, when the portal is opened, only the dim emergency lights are turned on, and the snake pupil magic lamps are all raised when Dumbledore gives the command.

The same is true for the defenses, which will only restore the power supply when they are touched, which is why Aini misjudged the danger level of the snake puppets before - the magic they contained at the time was very weak and there was no threat at all.

Thinking of this, Eni was amazed by Slytherin's methods, this genius design is still brilliant even today, thousands of years later, not only greatly saving mana, but also reducing the damage to magic patterns, and can extend the life of various structures.

Decades ago, Voldemort relied on his own bloodline to find a way to steal some of the Slytherin's permissions, and was able to turn the escaped magic into a curse.

After the complicated magic circle that had been running in the hall for nearly a thousand years was restored, the power of the curse generated was almost none, which showed that the entire magic pattern system was precise and smooth, and the use of magic power was extremely efficient.

But the vast amount of magic poured into the Slytherin statue was gone, and only a small amount of cursed power traced back to the veins, and it was clear that the magic was not senselessly dissipated, but was useful.

Aini stared back and forth at the statue, but a curtain of light that was hard to see prevented him from prying eyes, but knowing the plot, it was not difficult for him to guess where the magic was going.

Basilisk.

From the environment and traces here, it can be seen that there have been no traces of large-scale biological activity for decades, and if the basilisk can still go out to forage through other passages, it will never be invisible for thousands of years.

After all, the water has left traces, and the geese have left sounds, let alone such a very aggressive big guy.

It can also be seen from the content of the original trajectory basilisk voice that this big guy has been holding back in the secret room for a long time.

Therefore, the vanishing magic is most likely used to maintain the survival of the basilisk, and once it is released and cannot be sent back, it will be a lot of fun.

Without the consumption of the basilisk, the remaining mana will be transformed into a terrifying curse, and I am afraid that the appointment letter of the Hogwarts Defence Against the Dark Arts professor will basically be equivalent to a death notice.

Although in Aini's recent plan, the stronger the curse, the better, but there must be a limit.

Just like a herbicide, the right amount of use can save manpower, and it will not have much impact on the crops, if you throw half a ton of land......

If all the magic power swallowed by the statue turns into a curse, the entire castle's magic system will be disturbed, and many functions will be weakened or even invalidated.

Aini suddenly remembered the last battle in the movie, after the outer barrier was captured, the castle's performance during the internal battle was really spicy, and it was actually in tatters and almost demolished into ruins.

This is not a Muggle castle, it was founded by definition as a fortress of war, and it was also a fortress of magical warfare in the age of chaos.

Obviously, the Big Four had considered the problem of being invaded inside, such as the staircase moving around, which was a defense that annoyed many new wizards.

Maybe...... It's not that the Big Four's craftsmanship was too poor at the beginning, but that the function of the castle itself is missing, and the defense has declined.

"I probably know where the magic goes, so it's better not to touch this door for now."

Walking up to Dumbledore, Eni recounted his speculations about the basilisk.

"Anyway, the materials I got now are enough, so I really don't have to take any risks."

Dumbledore nodded in promise, and it wasn't too late to leave the secrets behind for later exploration. He trusted Aini's judgment of the basilisk, after all, the Scamanders were experts in this regard.

The two of them were busy underground for a long time, and later teleported together to the bathroom at the entrance and arranged it again.

Before leaving, Ernie splashed some water on the door, and later on, Dumbledore, hearing Filch's complaints, approved his request to close the door to the bathroom.

So in the afternoon, when Myrtle came back from the prefect's bathroom, she found that her territory was tightly sealed by wooden boards......

The main thing is that a few gadgets placed by Dumbledore are equivalent to surveillance, and if they are not sealed, if a little girl suddenly has a stomach trouble nearby, wouldn't he become a pervert who peeps at the girl's toilet?

Seeing that it was time for dinner again, the two walked towards the auditorium together.

But I didn't know that in a certain secret passage, two brothers were staring at the map in their hands in shock.

"That man was Dumbledore."

George swallowed dryly, and his eyes followed a small dot to the staircase, reconfirming the name displayed.

"I know."

Fred replied dryly, and even the movement of his eyes was exactly as large as that of his brother.

"That room should be the girls' bathroom."

For the terrain of Hogwarts, the two of them know it well, at least the commonly used areas will never be mistaken.

"I know that too, but ......."

Fred scratched his hair irritably, and then the two of them said in unison, "...... Why is Dumbledore in the women's bathroom?"

The twins only felt that everything was not going well today, first they encountered a secret passage that could not find an exit, and then they saw the headmaster constantly wandering around the girls' bathroom, and the irritability in their hearts kept increasing one, plus one, plus one.

If Snape or Lockhart were caught doing something like this, they would have laughed and spread the word all over Hogwarts, including a set of scripts if they had added money.

But when the subject became Dumbledore, the two of them were only distressed and incredulous.

Since the twins entered the school, the old principal has shown great tolerance and kindness to the two leather children, for which they have always been very grateful.

The two looked at each other, unwilling to believe that the perfect person in their minds would do such a thing.

"I see!"

Fred slapped his thigh hard in a flash of realization.

"Ahh

George screamed in pain and said angrily, "Can you shoot your own next time?"

"It doesn't matter, brother. Think about it, is this possible......

Fred moved the map closer and circled Myrtle's bathroom with his finger.

"Although it was true that Dumbledore had entered the girls' bathroom, it occurred to me that Angelina had said that there was a strange ghost that was resident there, and that it was now almost abandoned, and that no one usually went there."

George's eyes lit up, "You mean Dumbledore didn't go there to do anything strange, but because it was convenient to do something secret?"

"That's right, so we're ......."

The two laughed, and suddenly felt that today was their lucky day, not only found a challenging secret passage, but also discovered a new point of exploration.

Putting away the map, the twins hummed a little song and continued to look for the exit, deciding to sneak over at night to have a look.

When it comes to the secrets of the chief mage of the Wizengamot, I'm looking forward to it when I think about it~
