Harry and the others looked curiously inside the door, and then they were surprised.

I saw that inside was a huge chessboard, and in front of it were black chess pieces, which were all taller than them, as if carved out of black stone, and then I found that on the way through the room stood a row of white pieces, and the five little ones could not help but tremble slightly-it turned out that those standing white pieces were all faceless, as terrifying as faceless people.

"What do we do now?" Harry asked in a low voice.

"Obviously, isn't it?" Ron said. "We're going to play chess to get through this room." Because behind the white pieces, they already saw another door.

"How?" Hermione asked nervously.

"I thought," Ron said, "we're going to make our own pawns." He approached a black horse, and touched the horse with his hand, and the stone came to life, and the horse scratched at the ground with its front hooves, while the knight on the horse turned his helmeted head to look down at Ron.

"We ...... Well...... Do you want to join your side, and you have to win to pass? The Black Knight nodded.

"Okay, now it's either chess playing, or have Dorag come down and help flip the chessboard directly, which one do you choose?"

"No, I can't contact Dorag this far away." Sakura shook her head, "But we don't have to follow the rules, we can't get over the ground, why don't we fly over?" Didn't you have a broomstick in the room just now? ”

As soon as Sakura said this, Harry and Ron immediately felt stupid, and even Hermione was a little embarrassed, because she didn't think of this either.

"Okay, let's go back and get the broomsticks, but there are only three brooms, who will keep the remaining two?"

Depending on the situation, Ron will definitely not give up.

"Are you stupid? It's not a Quidditch match now, and who rules that broomsticks can only sit for one person? ”

Draco was-for-tat, but the advice was still useful, so he flew over the asylum...... I mean, after the chessboard, they went to another room.

"Hmm...... All I can say is that it's good that we don't have to duel this big guy. ”

Harry covered his nose, there was a giant monster in the room that was bigger than they had seen on Halloween before, but there was a bloody lump on its head that protruded and lay there motionless.

"Hurry up, I can't stand it."

Hermione urged, and the group of five entered the next room.

Neither of them dared to look at what was inside when Harry pushed open the other door, but to their surprise there was nothing scary inside, only seven bottles of different shapes neatly arranged on a table.

"It's Snape's trick," said Harry, "and what are we going to do?" ”

As soon as they walked past the threshold, a fire burned at the entrance behind them, and it was no ordinary fire, for it was purple. At the same time, a black fire burst into flames at the doorway leading to the front. They're stuck in the middle!

"Look!" Hermione pulled a piece of paper from the side of the bottle and beckoned Harry to look at it. The paper reads: There is danger in front of you, and there is safety in the back, and if you find it, two of us can help you, one of the seven will help you keep going, the other will send you back to where you are, and two bottles are just ordinary nettle wine, and three are deadly poisons/medicines.

If you don't want to stay here forever, go for it! To help you choose, we have four tips:

First of all, no matter how secret the poisoned liquor is, you can always find them on the left side of the nettle wine.

Secondly, it's always a different wine standing on the edge, but if you keep moving inward, there's no good wine.

Thirdly, as you can see, all bottles of different sizes, short or tall bottles, are not dangerous.

Finally, the second on the left and the second on the right are actually a pair, although they don't look similar.

After reading this, Hermione let out a heavy sigh, but when Harry looked at her, he was surprised to find her smiling.

"Wonderful," said Hermione, "it's not magic anymore, it's a test of logical reasoning, a riddle." There are many great wizards who are not good at guessing puzzles, so they have to be locked up here forever. ”

"We'll do the same, right?"

"Of course not," Hermione said confidently. "Everything was told to us on this piece of paper. There are seven bottles of wine: three are poisonous and two are normal, one will allow us to pass safely through the black flame and the other will bring us back to the place through the purple flame. ”

"But how do we know which bottle to drink?"

"Give me a minute." Hermione read the note a few more times, then walked back and forth around the row of bottles, pointing at them and muttering to herself, and finally, she clapped her hands.

"That's it!" She said, "The smallest bottle will lead us to find the Philosopher's Stone through the black flames!" ”

Harry looked at the vial. "There was only one person's serving, and it was barely enough to swallow a mouthful. So which bottle will make people go back through the purple flames? So Hermione pointed to the round bottle on the far right.

"Well, only one person will go in this time," said Harry, "I don't think anyone can fight with me, Voldemort killed my parents, I have to go in!" ”

"What can you do alone?"

"Uh...... Sakura, can you lend me the Genga? ”

"No," Sakura shook her head, "the Geng will only protect me when I'm in danger, and won't listen to other people's orders." ”

Harry was feeling a little regretful before Sakura continued, "But who told you we could only go in alone? ”

"What?" Harry was pleasantly surprised.

"Wait!" Hermione looked at Sakura, "This is the Calendar Fire, the legendary flame from hell, only a very dangerous dark wizard can summon and command it, you don't have the ability to extinguish it." ”

Sakura smiled faintly, "Since only dark wizards can use it, who placed it here?" ”

Hermione paused for a moment, she hadn't really thought about it.

Sakura walked straight to the flames and opened her hands, and a black magic force visible to the naked eye gradually condensed.

"I can't extinguish it, but it's okay to guide it and make a way for it."

Black flames moved to either side, revealing a path.

"Hurry up, I won't be able to last long!"

A few mermaids entered, and then Sakura followed, and then they saw an empty room with only a mirror, and in front of the mirror was a hooded figure with his back to the five people.

"You're finally here, I've been waiting for you for a long time."
