The three of them performed their own duties and started to act. With the busy work of the two players Ahi and Harry, they soon grabbed the key of the light blue wings in their hands!

Putting back on the broom, Yaxi walked towards the wooden door, and the key was still struggling in his hand. He inserted it into the lock and turned it - the lock was opened! As soon as the lock was opened, the key immediately flapped its wings and flew away. After being caught twice, it looked very haggard.

"Are you ready?" Yaxi asked the other two people with his hand on the door handle. Seeing that they nodded, he pulled the door open.

The house was very dark at first, and they couldn't see anything inside, but as soon as they stepped in, the room was filled with light, so they saw a shocking scene.

They were standing on the edge of a giant chess board, with black pieces in front of them. These pieces were taller than them, like carved from black stones. Then they found that there were rows of white pieces standing on the way through the room. Harry and Ron couldn't help but shivered gently - it turned out that all the white pieces standing were faceless.

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

"Obviously, isn't it?" Ron said. "We're going to play chess and go through this room."

"Yes, this should be Professor McGonagall's masterpiece!" Yaxi said while looking at him in amazement.

Behind the white chess piece, they had already seen another door.

"How to get it?" Harry asked nervously.

"I think," Ron said, "we have to make our own pieces."

He approached a black horse and reached out to touch the horse. The stone horse came alive, the horse grabbed the ground with its front hooves, while the horse's knight turned his helmet-wearing head to look down at Ron.

"We—well—are we going to join you and win to pass?"

The Black Knight nodded, so Ross returned to his two companions. "It's a bit troublesome," he murmured, "I think we're going to replace the three black spies..."

"Good Ron!" said Yaxi, "You are absolutely right. But I think if we treat it as chess pieces, we will definitely get hurt! We need a better way!"

"Ashi, do you have an idea?" Harry said.

"That's right!" After Yaxi said that, she stretched out her wand, recited a spell at the chess piece, and kept shooting onto the chess piece.

In the surprised eyes of Harry and Ron, the pieces turned into large stones - they were just stones.

"It's time to finish the work!" Yaxi smiled and put down her arm, taking the lead in walking towards the exit.

After easily cracking several mechanisms in succession, Harry and Ron seemed confident to complete the next thing.

"Guess what level there are?" Harry said, "Look, we have seen Sprout's 'devil's net', and those flying keys must be Professor Naflivie's masterpiece. Professor McGonagall made any moves on those chess pieces so that they could survive-then only Quirrell's spells and Snape..."

As they were talking, they came to the front of another door.

"Get in."

Yaxi pushed the door open. A moldy smell immediately penetrated their nostrils, forcing them to cover their noses with clothes. Tears were smoldering their eyes, and they saw clearly that on the floor in front, a cave giant was much larger than the one they had caught. But a bloody lump struck out on the head and lay motionless.

"It's really good, we don't have to fight it," Harry whispered as they carefully stepped over its huge legs. "Hurry up, I can't breathe anymore!"

As Ahi pushed open the other door, Harry and Ron hardly dared to look at what was inside-but unexpectedly there was nothing scary inside, only seven bottles of different shapes lined up neatly on a table.

"It's Snape's trick," said Harry. "What are we going to do?"

As soon as they walked past the threshold, a ball of fire burned at the population behind them—it was not an ordinary fire, because it was purple. At the same time, a ball of black fire lit up at the door leading to the front. They were trapped in the middle!

"Look!" Ron pulled out a piece of paper from the bottle and showed it to Axi and Harry. The paper was written like this:

There is danger in front of you, and the back is safe. If you find it, two of us can help you, one of the seven will help you continue to move forward, the other will send you back to where you are, and two are just ordinary Zunma wine, and three are deadly poisonous wine.

If you don’t want to stay here forever, choose now!

To help you choose, we have four tips: First, no matter how secretly the poisoned wine is, you can always find them on the left side of nettle wine; second, the wines that stand on the edge are always different, but if you continue to move inward, there is no good wine; third, as you see, all bottles of varying sizes, and short or tall bottles are not dangerous; fourth, the second on the left and the second on the right are actually a pair, although they don't look like each other.

After reading it, Ron sighed heavily, "How should we choose this?"

Harry looked at Yaxi, "You will definitely have a solution. Yaxi, your magic potion is very good!" "This is no longer witchcraft, this is a logic test - a mystery. Snape is so tired of it." Yaxi curled his lips, as if he was disdainful of Snape's tricks.

"Yaxi, you already know the answer?" Ronqi said.

"Of course! Everything tells us on this piece of paper. There are seven bottles of wine in total: three are poisonous; two are regular wine; one will let us pass the black flame safely and the other will let us return to our place through the purple flame." Yaxi said, "But what I'm thinking about is how we can pass this level together!"

Yaxi said, looking at the bottles, and by the time he finished speaking, he was already holding one of the smallest bottles in his hand.

Harry looked at the bottle. "Is this the antidote? But there is only one person's portion inside, which is almost not enough to swallow a bite. So which bottle will make people go back through the purple flame?"

So Ashi pointed to the round bottle lined up to the far right.
Chapter completed!
