The long and winding stone corridor was silent and tortuous. In addition to the sound of their own footsteps, there was also the sound of water droplets slowly dripping along the walls.

The corridor went downhill, which reminded Harry of Gringott.

His heart beat violently, and he remembered the legendary giant dragons guarding the wizard bank vault.

If they encounter a dragon, a fully grown dragon, Norber will be difficult to deal with. "Can you hear anything?" Ron asked in a low voice.

Harry listened carefully.

There seemed to be a gentle rustling sound and a jingling sound in front of me.

This kind of environment that is unknown is really frightening, but there is another existence beside him, and the curse prince Sherlock also came with him, which made Harry feel very safe.

They came to the end of the corridor, and in front of them was a brightly lit room with high vaulted ceilings.

Countless little birds as dazzling as gems, flapping their wings and flying around the room.

There is a thick wooden door opposite the room.

"You said, if we walked through the room, would they attack us?" Ron asked.

Ashinsa and Hermione glared at him at the same time, believing that such unlucky words should not be said at this time. The birds are actually keys. Although they are flying leisurely, they cannot be underestimated if they attack suddenly, because the front of the keys is also very sharp.

"Obviously, to know the function of these little things, you have to pass through this open space." Sherlock glanced at the dense winged key creatures in the air.

Harry took a deep breath, blocked his face with his arms, and rushed to the other end of the room.

He thought he would have sharp mouths and claws to tear him up at any time, but he ended up being safe.

He came to the door without any damage and pulled the handle, which was locked.

Sherlock came over with the other three, and Harry then pulled and pushed, but the wooden door did not move at all. Hermione tried her Alahoi cave to open the curse, which was useless.

"What should I do?" Ron asked.

"Didn't you notice that these flying keys above your head are actually the key to opening this door? If you look closely, it's not difficult to find that these little things are keys with wings." Sherlock looked around every corner of the room, while Ron and Hermione stared at the large group of flying keys.

"But there are hundreds of keys on it." Ron carefully looked at the door.

"We are looking for a large antique key, which may be silver and shaped like a door handle." Harry Ron Hermione began to pick up the broom next to her and rushed into the dense key group, searching carefully for the keys of the door.

Sherlock and Ashinsha were watching quietly on the ground. This was a coolie. Instead of flying up to search blindly, it would be better to stand down carefully and observe and find the key you want.

Sherlock observed carefully. Prometheus flew around with the keys. These iron keys seemed to be afraid of the high temperature of Prometheus. They immediately vacated a large area. In a moment, they found a large silver key hidden among the keys, with its wings drooping, as if it had been caught and was roughly stuffed into the keyhole.

The golden magic wand pointed to the key with sky blue feathers, and a magic hand was cast in a direction. The slightly listless key was instantly grasped by an invisible big hand in the air. After struggling for a few times, it found useless, the key was pulled and handed to Sherlock. It was obvious that it had become accustomed to this rough way.

Suddenly, the key in the sky was as crazy as he was heading towards Harry, Ron and Hermione who were flying in the sky. Ashinsha was very worried about Hermione's safety, and the tip of Sherlock's golden magic wand released a large ball of white clouds.

Zeus's appearance was like a large ball of soft cotton candy, and it quickly rose into the air to replace the three little wizards. All the keys flew into Zeus' clouds and could not move, as if they entered a quagmire.

Harry and the other two got off the broomstick and gathered next to Sherlock.

This immediately added another height to their worship of Sherlock.

"It should be this one." Harry asked with some uncertainty.

"You'll know if you try it." Sherlock picked up the key, stuffed it into the keyhole, and twisted it hard, yes, it's it.

With a click, the door lock bounced open and the key flew away again.

It was caught twice in a row and looked haggard.

"Are you ready?" Sherlock asked them with his hands holding the door handle. Everyone nodded, so he pushed the door open.

The second room was pitch black and there was nothing to see.

But as soon as they stepped in, the room suddenly became brightly lit, illuminating a shocking scene.

They stood beside a huge chess board, with black chess pieces in front of them, all taller than them, and seemed to be carved from things like black stones. On the other end of the room, facing them were some white chess pieces.

Harry, Ron and Hermione were trembling with fear, and the tall white pieces had no facial features on their faces.

Sherlock protected his sister behind her and observed forward.

"What should I do now?" Harry whispered.

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

They saw a door behind the white chess piece.

"How to do it?" Hermione asked nervously.

"In my opinion..." Ron said "we must act as pawns."

Sherlock touched his chin, "But it's a pity that I'm average in wizard chess skills and gameplay. Are there any experts among you in this field?"

Ron volunteered to agree with this. Whether it was Hermione, Ashinsa, or Harry, he never won when playing wizard chess with Ron.

"Okay, but we can change another way. Since there are chess soldiers blocking the way, then we might as well just destroy these chess directly?..."

Harry and others were stunned. Looking at these tall chess pieces, they didn't know what method Sherlock said to destroy them.

"Zeus is handed over to you."

"Okay dad."

Zeus floated to the chessboard, and his white body slowly became larger and thicker, and also changed from white to black. Zeus's appearance seemed to be angry, and black cumulus clouds enveloped the entire chessboard.

"Big Thunder!"

Zeus shouted loudly, and countless thunders as thick as buckets bombarded the chessboard, both the white and the black chess pieces turned into exploded shattered pieces.

"Dong!" A cracked stone fell on Ron's head, knocking the other party unconscious, and there was a big red envelope on his forehead.

"Oh, I couldn't control it, it's a bit powerful." Zeus floated back apologetically, while Harry was quite worried about Ron's injury. The stone must be the size of an adult's fist.

"He fainted, what should I do?" Harry asked anxiously.

"I can only let him stay here for the time being. Harry, please stay and take care of him." Sherlock said.

"What? I! But..."

Sherlock patted the other person on the shoulder, "Don't worry, with me here, no one will take away the Philosopher's Stone."

Harry looked at the destroyed chessboard, almost ruined, and swallowed, while Sherlock also took Ashinsha and Hermione to leave, leaving only the regretful Harry to take care of Ron, and did not care whether Harry was willing or not.

"What do you think will be next?" Hermione quickly followed Sherlock.

She and Ashinsha didn't think there was anything wrong with leaving Harry there. In fact, someone stayed is the most correct choice, and someone had to take care of Ron.

"We have passed Sprout's mechanism, that devil net. It must be Frevi who impersonated the keys. Professor McGonagall transformed the pieces and made them alive. Below are the magic of Kilow and Snape's." Sherlock answered Hermione's questions as he walked.

They came to another door.

Push the door open.

A disgusting smell came to their noses, so they had to lift their clothes to cover their noses.

The eyes of the two girls were also stained with tears. Through their blurry tears, they saw a giant monster, larger than the one they had last time. They lay motionless on the floor in front of them, losing consciousness, and a big bloody lump on their heads.

"That's great, we don't need to fight this troll." Hermione whispered.

They carefully stepped over the troll's thick legs.

"Go away quickly, I can't breathe." Ashinsha complained.

Sherlock opened the next door, and for a moment, the two girls couldn't dare to see what was waiting for them next, but there was nothing scary here, only a table, with seven bottles of different shapes on it.
