The second room was pitch black and nothing could be seen. But as soon as they stepped inside, the room was like a legendary tomb, and a line of fire lit up, and then the torches on the wall were lit one by one, and then the whole hall was illuminated, revealing a shocking scene.

They stood on the edge of a huge chessboard, with black pieces in front of them, all taller than them, as if carved from something like throwing black stone. At the other end of the room, facing them were white chess pieces, and those towering white chess pieces had no facial features on their faces.

"What now?" Harry whispered.

"It's not obvious?" Ron said, "We had to play chess to get to the other end of the room." ”

They saw a door behind the white pieces.

"How to play the law?" Hermione asked.

"In my opinion," Ron said, "we have to act as pawns." ”

He walked up to a black knight and reached out and touched his horse. Immediately, the stone came to life, the horse scraped the earth with its hooves, and the knight turned his helmeted head and looked at Ron. "Do we—um—have to come with you to get there?" the Black Knight nodded. Ron turned to the others and said, "We need to think about it," he said, "I'm afraid we'll have to replace the three black pieces here."

"Boom" Ron was talking happily when there was a loud bang in his ears. The others turned their heads and saw Zhang Feng carrying a mace in his hand, and a broken white chess piece next to him.

"I think this method can also pass!" Zhang Feng shrugged innocently, and the others opened their mouths.

Although Harry and the others froze, the white chess piece that was killed by Zhang Feng did not froze. They swarmed up and beckoned Zhang Feng with the weapons they had originally used to fight the sunspots. At the same time, the black chess pieces also rushed towards Zhang Feng, and it seemed that they should be punishing Zhang Feng, the rule-breaking person, together with the white chess pieces.

Harry and Ron were stunned by the scene in front of them, and when they saw the chess pieces rushing towards them, they subconsciously rolled towards the edge of the board. But Zhang Qiu and Hermione pulled their wands from their sleeves, rushed at Zhang Feng, and then stood in a triangle with him back to back.

Zhang Feng saw Zhang Qiu and Hermione coming, and then magically put away the mace in his hand, and then replaced it with a wand. After all, the three-person stance is definitely not suitable for a melee fighter in the middle.

At this time, the chess pieces of both sides had already rushed in front of them.

Zhang Feng and the three of them used the Splitting Spell to deal with the chess pieces that rushed over, but because the Splitting Spell was a relatively advanced spell, although the three of them could use it, the magic power consumption was very large.

By the time they used their magic to kill half of the pieces, the three of them had run out of magic.

At this time, Harry and Ron, who had just subconsciously hid on the sidelines, realized that they also belonged to this small team, and rushed up. Using the magic they knew, they attacked the pieces diligently, slowing them down. This gave Zhang Feng and the others time to be able to regain their magic.

After recovering a little of his magic power, Zhang Feng immediately replaced his wand with a mace, and took out two heavy weapons and handed them to Zhang Qiu and Hermione. He felt that it would be easier to use such heavy weapons against these pieces.

Sure enough, after changing weapons and fighting methods, soon those chess pieces were all killed. But Ron was also injured during the fight, and he couldn't move on. After giving Ron a town teleportation scroll, Zhang Feng teleported Ron back to the tower room in Gryffindor. Then they rushed through the door and down the next hallway.

"We've made it through Sprout's trap, the devil's web—it must have been Flitwick who enchanted those keys—Professor McGonagall had deformed the pieces, bringing them to life—and all that was left below was Quirrell's magic, and Snape's" Hermione still liked to share what she had analyzed with others.

They came to another doorway. "Okay?" Harry asked in a whisper. "Let's go inside. Harry pushed the door open. A disgusting stench hit their noses, and they had to lift their clothes to cover their noses. Tears were also in their eyes, and through the blurred tears they saw a troll, even larger than the one they had fought last time, lying motionless on the floor in front of them, unconscious, with a large bloody lump on its head.

"Great, we don't have to fight this troll anymore. Harry whispered. They cautiously straddled the troll's thick legs. "Let's go, I'm out of breath. ”

He opened the next door, and for a moment, the four of them couldn't look at what was waiting for them next—but there was nothing terrible here, just a table with seven bottles of different shapes lined up on it.

"Snape's potion," said Harry, "what should we do?"

No sooner had they crossed the threshold than a flame rose from behind them, sealing the doorway. The flame was unusual: it was purple. At the same time, black flames burst out from the doorway leading to the front. They were trapped in the middle.

"Look!" Hermione grabbed a roll of parchment that had been placed next to the bottle. Harry stood behind her, reading with her: danger in sight, safety 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 offer four clues to help you choose: first, no matter how cunning the poison is, they are actually on the left side of the nettle, second, the bottles on the left and right ends are not well contented, and they will not be useful to you if you want to move forward, and third, you will find that the bottles are not equal in size. There is no Grim Reaper hidden in the giants and gnomes, and the fourth, the second on the left and the second on the right, although they look different, have the same taste.

"Seven bottles: three for poison, two for wine, one to pass us safely through the black flames, and one to send us back through the purple flames. Zhang Qiu reacted immediately after hearing this.

"This smallest bottle will help us get through the black flames - the Philosopher's Stone. But there was only enough for one person to drink. Zhang Qiu added again.

"Harry, you drink potions. Autumn, Hermione, the two of you use the Flame Charm, and then control the fire to spread all over the surface of your body, and then you can go inside. Zhang Feng came in and looked at the small room and the trap, and finally gave his solution.

Harry took a deep breath and grabbed the smallest bottle. He turned to face the black flames.

"I'm coming. With that, he drank the liquid from the vial in one gulp.

It was indeed like ice, seeping through his whole body at once. He put down the bottle and walked forward. He plucked up his courage and saw the black flames licking his body, but he didn't feel anything—he couldn't see anything at that moment, only black flames in front of him—and he made his way to the other side, into the last room. Immediately afterwards, Zhang Feng, Zhang Qiu, and Hermione also used Zhang Feng's method to come in.

But they weren't the first to arrive, there was already one in there—not Snape, not even Voldemort.
