Hogwarts School of the Dark Arts

Faced with everyone's confusion, Harry only said that if Snape and Voldemort were together, then only him among the four would be likely to survive, because he had escaped.

"Ron, drink another bottle of potion and go back and write a letter to Principal Dumbledore first, and then tell Professor McGonagall that we are here to stop Snape."

"Xavier, Hermione, you two are here to guard. If I fail, you find a way to prevent Snape from leaving."

"I'll go in first. I don't know how long this potion will be effective. You guys should hurry up."

After quickly making arrangements, Harry took a deep breath and rushed toward the black flames.

The remaining three looked at each other, Ron took a deep breath, picked up the remaining bottle of potion and drank it in one gulp.

"I'll be back soon."

After saying that, Ron dove into the purple flames and went back to fetch reinforcements.

Looking at the black flames in front of him and the purple flames behind him, Xavier suddenly sighed.

"Don't worry, they'll be fine."

Hermione walked to Xavier and comforted him.

"I'm not worried about them, I just feel... a little bored." Xavier said as he picked up the parchment and tried to find the nettle wine from the remaining potions on the table.

"Bored? Why?" Hermione was stunned.

"Do you have a safe at home?"

Although she didn't understand why Xavier asked this question, Hermione still nodded after thinking about it.

"Yes," Hermione said.

"So where are the keys to the safe?"

Hermione: "My dad always had the key."

"Behind this door is the place where the Magic Stone is stored, so this black flame door can be regarded as a safe. Do you understand this?"

Hermione thought for a moment and nodded.

"So what do you think this potion that can help others pass through the black flames is equivalent to?"

"Key?" Hermione replied tentatively.

"Do you think it's reasonable to put the key outside or next to the safe? Especially since the safe is not empty and contains precious magic stones."

Hermione frowned suddenly, her brain running wildly.

At this time, Xavier had found two bottles of nettle wine, opened one of them and drank.

"Hermione, why don't you let me test you? So far we have encountered a total of six levels. Which professor set them up?" Xavier asked.

"The first level is Hagrid; the second level must be Professor Sprout of Herbology; the third level...the third level should be Professor Flitwick, who casts the magic on those keys so that they can fly; the fourth level must be It was set by Professor McGonagall, who is good at transfiguration; the fifth level is about trolls, and I remember Professor Quirrell is good at dealing with trolls, so it should be him; the sixth level is about potions, so it must be Snape."

Hermione analyzed and gave answers at the same time. The answers were very clear and she was really good at logical reasoning.

"So have you found that one of these six levels is incompatible with the other levels?" Xavier continued to ask.

"Is there any?" Hermione asked doubtfully.

"Each of the four deans have served at Hogwarts School of Witchcraft and Wizardry for many years, and Hagrid is deeply trusted by Principal Dumbledore. But what about Professor Quirrell? A person who has just returned to teach after many years of graduation, his own level is also very high. Not particularly high, why would he be involved in the protection of the Philosopher’s Stone?”

"And haven't you noticed that the levels set up by the four deans are more designed to test intruders than to protect the Sorcerer's Stone? Just like the current level, do you think that such a question can better protect the Sorcerer's Stone? , or is there no such question and only these two flames can better protect the magic stone?"

Hermione fell silent.

If there was no such question, then the intruder would be trapped here unable to advance or retreat, and the protective effect of the magic stone would be fully activated in an instant.

The same goes for wizard chess. If instead of playing chess, all the chess pieces are used to protect the door, the protective effect will also be greatly increased.

"So this is actually a game, a game used to expose Quirrell's true face, and by the way, to test the adventurous students." Xavier concluded.

"You mean Professor Quirrell is the one who wants to steal the Philosopher's Stone? But how is this possible?" Hermione said in disbelief.

"How is it impossible?" Xavier took a sip of nettle wine: "Or let me change the question, why do you think Snape wants to steal the Sorcerer's Stone? What was the starting point for this speculation in the first place?"

Hermione shook her head: "I don't know. Harry and Ron told me that they found Snape behaving strangely, probably because he wanted to steal the Philosopher's Stone. I don't know why they initially suspected Snape, but it seemed that it was because of Snape. Nap has been targeting Harry... He has indeed been targeting Harry, you should know this, right?"

"Snape's reason for targeting Harry is simple. He and Harry's father are in the same grade, and their relationship was very bad during school. If you are interested, you can ask Professor Flitwick in detail. When I asked him He only told me that their relationship was very bad, but he didn’t say how bad it was.”

Xavier said as he picked up another bottle of nettle wine, which tasted surprisingly good.

"But……"

"Would you like to make a bet? I bet that the person who wants to steal the Philosopher's Stone is not Snape but Quirrell. If you want to make a bet... how about I bet on the homework for the next school year? If I win, you will do all the homework for next year. Write, if you win, I’ll cover all next year’s homework.”

"Isn't this bet too big? Mr. Owen."

Hermione, who was about to speak, was startled. She quickly looked in the direction of the black flames and saw Principal Dumbledore walking through the flames, holding Harry in his arms!

Xavier, who was half sitting on the table drinking, turned his head.

"Sure enough, this clumsy trick to lure the tiger away from the mountain did not deceive you. Everything is under your control." Xavier said.

Principal Dumbledore smiled slightly and said: "Actually, I just suddenly thought that I forgot to bring something, so I came back."

"Is Harry okay? Is he..." Hermione asked nervously.

"I came back in time, and he was not seriously injured... I will send him to the hospital for treatment later... You guys should go back too."

"But the door quilt when you go back... eh?"

Hermione was about to say that the door was sealed by purple flames, but when she turned around to see where there was any flame, not only was there no flame, but the door was open.

"So, Principal Dumbledore, can you tell us whether it is Professor Quirrell who wants to steal the Philosopher's Stone?" Xavier asked.

Hermione immediately looked at Principal Dumbledore and saw him nodding.

Xavier nodded with satisfaction and left the table: "Then I'll go back first. I suddenly felt that the nettle wine tastes very good. I want to go back and think about whether I can change the taste to make it more suitable as a drink to be consumed with hot pot. ...Hermione, I’ll leave it to you to do next year’s homework.”

"As far as I know...Miss Granger did not agree to bet with you just now."

After saying that, Principal Dumbledore winked at Hermione.

Hermione understood and nodded immediately: "That's right, I didn't agree to the bet just now!"
