Although William can't use the fire curse and can't control the devil's flame, since this is a level, Dumbledore must leave the key to clear the level.

Several people walked to the table, and Hermione grabbed a roll of parchment that was placed next to the bottle, and she read:

Danger is in sight, safety is in the rear. Two of us can help you. Drink them down, one will lead you forward, and the other will send you back to where you came.

Two of them are filled with nettle wine. Three are killers and are waiting in line. Choose, unless you want to be here forever.

We also provide four clues to help you choose: first, no matter how cunning the poisons are, they are actually on the left side of the nettle wine;

Second, the contents of the bottle are different at the left and right ends. None of them will work for you if you want to move forward; Thirdly, you will find that the bottles vary in size.

There is no hiding of death in giants and gnomes; Fourth, the second on the left and the second on the right, although the appearance is different, the taste is the same.

After listening to it, William smiled and said, "A simple logical reasoning question, I don't know who made it." ”

"These potions were all configured by Professor Snape, and he should have produced them." Cedric glanced down at a few bottles.

Hermione smiled as well, "Many of the greatest wizards don't have the slightest ability for logical reasoning, and they're stuck here forever, but it's not too difficult. ”

William nodded, to be honest, Muggles are much better than wizards in this regard, and their subject education guarantees them, many times they have a strong sense of logic.

"So let's see who deduces first?" Hermione suggested.

William conjured a piece of parchment with his wand, held a quill and smiled, "You guys reasoning, I'll leave a little gift for Professor Snape too." ”

William thought for a moment, and quickly wrote on the parchment:

Professor Snape and Professor Dumbledore each have a non-zero natural number in their hands, and the product of the two numbers is known to be either 8 or 16.

Snape: "I don't know Dumbledore's numbers. ”

Dumbledore: "I don't know Snape's numbers. ”

Snape: "I still don't know. ”

Dumbledore: "I still don't know"

Snape: "I see"

Dumbledore: "I know, too. ”

What are the numbers in the hands of the two of them?

Once William had written it, it was placed on the table, and Hermione had already guessed the answer to the question that Snape had left behind.

She clapped her hands happily. "Got it, this smallest bottle will help us get through the black flames."

William picked up the inconspicuous little bottle and sniffed it carefully, again a potion he had never seen before.

Professor Snape was so hidden, he could even invent a potion to resist the devil's flames, it was terrifying.

"Is such a small bottle enough for a few of us to drink?" Cedric asked.

William used Transfiguration to conjure six straws, "A few drops per person is still enough." ”

William sucked a few drops through a straw and put them in his mouth, and the taste was like ice, and it seeped all over his body at once.

Several people carefully inhaled a few drops, and finally there was a small sip left in the small bottle.

William left all potions except for the bottle of nettle wine.

"This is a potion that can suppress the devil's flames, I want to study it." William said seriously, "Try to find out the ingredients of the potion." ”

"Can this be studied?" He said with keen interest.

"Of course you can, you only need to use Scarpimpin's manifestation charm to analyze the composition of the potion, but this is also quite complicated, and it will take a long time to try." William explained.

"And these bottles of poison, since they were configured by Professor Snape, they must be very toxic.

I'll also try to see if I can make an antidote, according to Gobarott's third law...... The antidote to a mixed poison is greater than the sum of the antidotes for each individual ingredient.

Not only do we have to choose the antidote to each individual ingredient, but we also have to find additional ingredients that can transform the various disparate ingredients through an almost alchemical process......"

Everyone was listening to the Heavenly Book, because William was talking about the content of the advanced potions textbook, which was already in the sixth grade.

Hermione, though she didn't understand, looked interested, and seemed to sound interesting about this method.

After a while, William was the first to enter the devil's flame, and he saw the black flames licking his body, but he didn't feel it.

For a moment, he couldn't see anything, only black flames in front of him—and then he made his way to the other side, into the last room.

It's a spacious, beautiful circular room filled with all sorts of funny little sounds. On the table with slender legs, there were many strange silverwares, spinning and belching small puffs of smoke.

The walls are covered with portraits of the old headmasters, all of whom are snoring softly in their frames.

But it's all snickering.

Hey, this room is so familiar.

"Uh- isn't this the principal's office?!"

On a September day, William only felt cold in his hands and feet, and turned around to leave.

Dumbledore set up such complex levels just to know who would travel at night?

It's fishing enforcement!

It's boring!

He was about to turn around and go back when Cedric and the others swarmed in.

Fred looked at the silverware on the table and laughed, "Is this a reward for us after the level?" ”

Reward a fart!

William hurriedly told him to shut up, and at the same time lowered his voice, "Hurry up...... This is Dumbledore's office......"

Several people's faces stiffened, and they quickly turned around and wanted to leave.

"Since you're here, why don't you talk for a while? I would love to talk to the young wizards before bedtime to get to know the psychology of the students.

I wonder even more, why are they here when they don't lie in their beds at twelve o'clock in the morning? ”

The door to the office bedroom suddenly opened, and Dumbledore walked out in a fluffy purple dressing gown with a nightcap with a ball on his head.

In Dumbledore's arms, holding Bobo Tea, it was looking at William with an innocent face and meowing weakly.

I really came to the principal's bed late at night!

William stood at the front, smiling awkwardly, and Hermione hid behind him, trying to reduce her presence and not be noticed by the headmaster.

"I'll just say don't come!" If it weren't for Dumbledore being here, the girl would have been shouting.

"Sit down." Deng Buliduo said kindly.

Six chairs appear under everyone's buttocks.

"Have a drink?" Dumbledore muttered: "It's good milk, a glass of milk before going to bed, it's good for the stomach." ”

Dumbledore waved his wand, and six cups of steaming milk appeared on the table.

"Ah, Bobo Tea, you're here." William seemed to have just suddenly seen his cat.

He stubbornly said, "I thought you were missing, so I brought them to look for you late at night, but I didn't expect you to be here with the principal...... Ahaha......"

Cedric and the others all nodded hurriedly, and laughed seriously, as if they agreed with William's statement.

Dumbledore smiled and sat down in his chair.

"So, you have violated at least a dozen school rules, how many points should I deduct from you?"

Dumbledore said happily.
