"Please come in!"

There was a soft knock on the door outside the principal's office.

The door opened, and Professor McGonagall walked in, glancing at the mirror on her desk, handing a document to Dumbledore.

"The review of Mr. Albert Anderson and Miss Katrina McDoug's time turnaround applications has closed," she said. ”

The Ministry of Magic is very strict about the management of time turners, except for Hogwarts students, they are basically not loaned, and the final step of strict review requires Dumbledore's signature and approval.

Well, it's not about the Headmaster, it's Dumbledore managing this thing right now, and for that reason, it's easier for Hogwarts students to apply for a time turner to complete their coursework.

Dumbledore picked up the quill, signed his name on it, handed the application back to Professor McGonagall, and asked, "What else?"

"Are you really going to leave the Philosopher's Stone at Hogwarts?" Professor McGonagall asked, frowning.

A few days ago, Dumbledore had asked several professors at the school to help design a mechanism to protect the Philosopher's Stone to ensure that it was protected in the strictest possible way and that no one could steal it.

"Aside from Gringotts, I'm afraid only Hogwarts can be considered safe, although it's a bit of a boast to say so. Dumbledore pretended to be embarrassed.

"You don't need to be humble, everyone knows that the only thing the mystery man fears is you!" Professor McGonagall said helplessly.

Although Dumbledore didn't say who had set his sights on the Philosopher's Stone, Professor McGonagall was still keenly aware of something.

The mysterious man may still be alive and eyeing the Philosopher's Stone.

Although Professor McGonagall found the idea ridiculous, there was no doubt that the Philosopher's Stone was a very powerful Dark Wizard.

Few people could break into Hogwarts without warning, let alone steal something right under Dumbledore's nose, but Professor McGonagall didn't want to put the students of Hogwarts in unnecessary danger because of the Philosopher's Stone.

After all, if the other party can break into Gringotts and get rid of the pursuit of the goblins, it is definitely not an easy guy to deal with.

"I still don't think it's a good idea, and Harry Potter is going to be going to Hogwarts. Professor McGonagall whispered.

Originally, Dumbledore had given Harry over to Muggle relatives to raise in order to keep him out of danger.

"It's safe here. Dumbledore said calmly, "Believe me, if Hogwarts is not safe, I am afraid that the whole of Britain will never find a safe place again." ”

Just then, there was another knock on the door to the Headmaster's room, and Snape walked in, glancing at Professor McGonagall, and said to Dumbledore, "I've set up the mechanism, and while most wizards have average logical abilities, I doubt it will be able to stop the Philosopher's Stone from being spied on by the most skilled dark wizards." ”

"It doesn't matter, I don't expect those mechanisms to completely stop anyone else from prying into the Philosopher's Stone. "Snape was clearly not optimistic about Dumbledore's approach. "By the way," Quirrell was going to hire a troll security guard to guard the facility, you know......"

Snape's face twitched a few times, and he continued, "Those trolls have brains the size of walnuts, and they can easily cause other problems. ”

"I think Professor Quirrell will take care of this. Dumbledore said.

"Are you serious?" Professor McGonagall frowned after Snape left, "Are you really going to let trolls into Hogwarts Castle?"

This strikes Professor McGonagall as ridiculous.

Dumbledore didn't expect the Hogwarts professors to design mechanisms that would keep prying eyes outright, but if someone tried to crack them, it would take at least some time, and that would buy him enough time.

Hogwarts can't apparitions, the castle is the biggest trap for Dumbledore, as for how to ensure that the Philosopher's Stone is not easily taken away by the other party, Dumbledore has already thought of an excellent way, even a superb dark wizard can't successfully get the Philosopher's Stone in a short time, and he will be blocked by Dumbledore, this is not Gringotts, but there is no place for the other party to escape.

As for the fight, Dumbledore was not afraid of anyone.

"Tom, what are you going to do? Dumbledore crossed his hands and muttered to himself.

......

In the Defense Against the Dark Arts office, Quirrell had just sent Snape away, and Dumbledore had granted his request to hire troll bodyguards to guard the facility.

"What should I do?" Quirrell muttered softly, looking out the window.

The mechanism set up by the Hogwarts professors seemed ridiculous to Quirrell, and it was impossible to stop him, but it was difficult to steal the Philosopher's Stone through the mechanism without making any noise.

This meant that he had to follow the rules and crack the mechanisms left behind by the Hogwarts professors one by one, which would take a lot of time.

Brute force cracking is undoubtedly faster, but it will be very troublesome, not to mention Dumbledore, and will be wanted by the Ministry of Magic, and there will be a lot of follow-up trouble.

To make matters worse, Dumbledore told the professors not to tell anyone else how to crack the mechanism, was he suspicious of the professors in the school?

Are you suspicious of me?

This is not good news.

"Don't do anything superfluous, it's not the time yet, you need to look for a suitable opportunity. A hoarse voice came from the turban behind Quirrell's head.

"Dumbledore doesn't value the traps you arranged, he just made a rule that those who had the idea of playing the Philosopher's Stone had to abide by, and the traps that guarded the Philosopher's Stone were just a bait to lure others to the bait, and his strength was the final guarantee. ”

Voldemort easily saw through Dumbledore's tricks, this is Hogwarts, his Dumbledore's territory, and if he makes a move, he will be targeted immediately.

Even if he could really grab the Philosopher's Stone in the end, he would need to face Dumbledore head-on, and almost no one but him could get out of the way when he faced Dumbledore at Hogwarts, which was the old guy's real plan.

However, how could he be Dumbledore's opponent when he was weak!

Quirrell was silent, he had been horribly punished for his failure to steal the Philosopher's Stone, with Voldemort parasitizing him.

Until the moment he was parasitized, Quirrell regretted why he didn't run in the first place, why he didn't betray Voldemort directly.

However, it was already late, everything was already late.

Since being parasitized, his body has begun to become weak, if Quirrell doesn't want to die, he needs to get the Philosopher's Stone as soon as possible to prepare the elixir of immortality, if he can't get the Philosopher's Stone, at most, his life will come to an end.

Quirrell didn't want to die yet.

He muttered to himself, "I'll have to figure out what the other professors' organs are." ”
