"What kind of thing is this?" Ron, who came down the second, saw Zhang Feng coming down, and asked. It seems that everyone knows who the most knowledgeable person here is.

"Honestly, I'm glad to have this bunch of plants here. ”

"Thankfully!" Hermione screamed, "See what they're doing?"

She jumped to her feet, struggling to move towards a damp wall. She struggled because the plant had just stretched out its snake-like tendrils, wrapped around her ankles, and wanted to climb upwards.

Hermione and Zhang Qiu finally broke free before the vines could hold them firmly. The two boys, Harry and Ron, tried desperately to tear the vines apart, but the more they broke free, the faster and tighter the vines became entangled.

"Don't move!" Zhang Feng shouted at them, "This is the devil's net!"

"Oh, I'm so glad we finally know what it's called, and that helps us a lot. Ron huffed, dodging backwards to keep the vines from wrapping around his neck.

"Devil's Net, what did Professor Sprout say about Devil's Net, saying that it likes darkness and dampness—" Zhang Qiu shouted.

"Then set it on fire!" Harry was almost suffocating.

"yes—of course you can—but there's no firewood here!" Hermione said aloud, wringing her hands anxiously.

"Are you crazy?," Ron yelled, "are you a witch or not?"

"Oh, yes!" Hermione said, drawing her wand and waving it, muttering words as it spoke, and a blue bellflower-like flame shot out of its head. In just a few seconds, the two boys felt the vines flinching away from the light and warmth, loosening the grip on them. The plants twisted and twitched, automatically releasing the tendrils that were wrapping around them, and Harry and Ron finally broke free.

Zhang Feng had already relaxed himself before they had this conversation, and then broke free from the devil's net.

"This way. Harry said, pointing to a stone hallway. This is the only way to go.

They heard, in addition to their own footsteps, the sound of droplets of water dripping slowly down the walls.

"Can you hear anything?" Ron asked in a whisper.

Harry listened. There seemed to be a soft rustle and clanging sound ahead.

"Could it be a ghost?" Harry's imagination was strong.

"I don't know, it's like the sound of wings flapping. Hermione said.

"There's a light ahead—I see something moving. "Zhang Qiu's eyes are still very good.

They came to the end of the hallway, and in front of them was a brightly lit room with a high vaulted ceiling. Countless small birds that were as brilliant as jewels flapped their wings and flew around the room. There is a heavy wooden door opposite the room.

"Do you think they're going to attack us if we go through the room?" Ron asked.

"Possibly. "They don't seem to be vicious, but if they all rush at once, I'm afraid I don't care about it, and there's no other way for me to run over anyway." ”

He took a deep breath, shielded his face with his arm, and sped to the other end of the room. He thought that at any moment there would be a sharp mouth and claws to tear him apart, but he was safe. Unscathed, he came to the door and pulled the handle, which was locked.

Others followed. They pulled and pushed together, but the door didn't move, and Hermione tried her Alaho Cave Spell to no avail. Of course, this also has something to do with her lack of magic.

"What should I do?" Ron asked.

"These birds can't just be used for decoration. Hermione said. They watched as the birds flew overhead.

"They're not birds at all!" Zhang Qiu suddenly said, "They're keys! Winged keys—take a closer look." ”

Harry realized the same and looked around the room.

"Yes, you see! Broomsticks! We must go up and get the key to that door! But there are hundreds of keys on there!"

Ron looked closely at the lock on the door, "We're looking for a big, antique key—probably silver, shaped like a doorknob. ”

Harry, as the youngest Quidditch Seeker in a century, wasn't in vain. He picked up a broomstick and searched, and after a minute of swirling through the swirls of colorful wings, he noticed that the wings of a large silver key were hanging down, as if it had been grabbed and crudely stuffed into the keyhole. Despite his slow broomstick, Harry was able to grab the key after a minute.

Harry landed quickly, and Harry ran towards the door, the key still struggling in his hand. He shoved it into the keyhole and twisted it hard – yes, it was. With a click, the door lock flicked open, and the key flew away again. It was caught twice in a row, and looked emaciated.

Harry pushed the door open.
