Under the combined spell of everyone, the black and white chess pieces finally stopped moving, but they still couldn't pass because the black and white chess pieces stood in place and attacked without gaps.

They were trapped in the middle of the chessboard.

"Now how are we going to get there?" said Harry, gasping for air as he propped his legs on his hands.

The others weren't much better, and in order to stop Professor McGonagall's spell, they had used up more than half of their magic.

Dudley sighed and looked at the already broken chess pieces next to the chessboard, no wonder Voldemort would honestly play chess to pass this level, "Miscalculated!"

In order to pass this level violently, a lot of mana must be consumed, and Voldemort would definitely not choose to do so.

"Hey!" Dudley sat on the floor in prostration, wiping the sweat from his forehead, his magic drained the most of all the people, and it wasn't for Professor McGonagall, if it weren't for Harry, Ron, and Hermione, he wouldn't have been able to stop the spell that Professor McGonagall had set for him.

Ron looked at the scene in front of him, now struggling to walk, and said in frustration, "We're stuck here. ”

"It's not like being trapped. Dudley said, pulling out four vials of potion from his wizard's robe and handing them to the group, "Drink it." ”

He took the lead in drinking the potion, but fortunately he prepared a hand in advance, otherwise let alone guarding the Philosopher's Stone, he was afraid that it would be cold here.

The taste of the potion is bitter, and after drinking it, the stomach is cold.

"What is this?" asked Hermione, looking at the silvery white viscous potion in the glass bottle.

"Potion of return. ”

This potion sounds like a lofty potion that restores magical powers, but few people in the wizarding world would make it.

It works a bit of a trick, and although it can restore mana, it's slow and one of the potions is expensive, and no one usually drinks it in battle.

It's like in a dark wizard duel, either you die or I die, the magic consumption is too great, and it's completely useless to drink this, and you still have to lose.

Thankfully, Dudley made this potion to be on the safe side.

After all, if you want to be careful, you have to prepare a few more hands.

It took half an hour for them to regain their magic that could basically cope with the rest of the situation.

"It's time to go. Dudley said.

"What are we going to do?" Harry didn't understand how to get through the pieces, which attacked without gaps, and there was no way for them to get through.

"Reduction," Dudley waved his wand at the front piece, only to see that the piece turned into a huge stone, "This level is designed by Professor McGonagall, and the counterspell of Transfiguration is reduction. ”

"I see. Ron also tried, but the reduction technique he used only turned the lower half of the chess piece into stone, and he looked at the crowd and smiled awkwardly, "I'm really bad." ”

"It's okay, it's just that your wand doesn't match yours. ”

"Dudley, don't comfort me. Ron was reluctant to clench his wand, and both Harry and Hermione were able to reduce the pieces to stone perfectly.

He bit his lip hard, he was really unwilling, he had trained hard, but no matter how he trained and cast spells, his level still had not improved significantly.

"Ron, I'm not consoling, your magic can actually restore this piece, you can ask Ollivander to buy a wand of your own. Dudley patted Ron on the shoulder, remembering that the wand Ron was using was not his own, and there was no way around it.

A wand that can't match itself can't fully exert its owner's abilities.

This was something he had only discovered after passing through the strange wooden door, and the spells he cast were more powerful and faster without the magic factor, simply because he had progressed to the point where death was more compatible with his wand.

After all, his wand is made of purple shirt wood and Thestrals, which represent death and reincarnation.

"Okay~" Ron's mood was much better, but he couldn't be happy at the thought of buying a new wand, and their family didn't have the extra money to buy a new wand.

The group finally passed the disgusting chess array.

Dudley pushed the door open.

A disgusting stench hit their noses, and they had to lift their clothes to cover their noses.

The eyes of the four of them were also smoked with tears, and through the blurred teary eyes, they saw a troll. The troll was even bigger than the one they had fought last time, lying motionless on the floor in front of it, 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. "Dudley, let's go, I'm out of breath. ”

"Wait," Dudley took a closer look at the troll's wound as he brushed his hand over the troll's wound, "this ......"

"What are you looking at?"

Dudley shook his head, "Let's go." ”

The smell was so sour, Harry couldn't wait to open the next door, and for a while, several of them rushed in, Ron and Hermione blushed and breathed heavily, the two of them had been holding their breath for a long time.

Dudley was the last to cross the threshold.

Then.

A flame rose from behind the crowd and sealed the doorway. The flame was unusual, purple. At the same time, black flames burst out from the doorway leading to the front. They were trapped in the middle.

There was only one table in the room, on which were lined up with seven bottles of different shapes.

Harry looked at the two flames and said suspiciously, "What should we do?"

Dudley touched the corner of his chin and hung up on WeChat, Professor Snape's fire magic was really amazing, he was able to use the most powerful black flame.

The slightest touch of this flame will turn into a pile of slag.

"Look!" Hermione picked up a roll of parchment that had been placed next to the bottle and read.

"Danger is in sight, safety is in the rear, and 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 were nettle wine, three were killers, and they were waiting in line. Choose, unless you want to stay here forever. ”

"I'll give you 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 contents of the bottles on the left and right are different, and they won't be useful to you if you want to move forward, third, you will find that the bottles are of different sizes, and there is no Grim Reaper hidden in the giants and gnomes, and fourth, the second on the left and the second on the right, although they look different, they taste the same. ”

Hermione let out a long sigh, a confident smile on her face.

"You're still laughing," Ron couldn't laugh anyway, what first and second, he didn't understand at all.
