With the creak of the door opening, a low bark immediately rang in their ears. Seeing that it was Charon, Louwe began to purr and coquettishly.

Charon stepped forward, touched Lu Wei's head, and relied on the heart of many days of domestication, and even drew a picture to let Lu Wei understand what he meant. In bad news, Louwe said that the big man Hagrid had indeed just arrived.

The crowd panicked, and Charon unchained Luwei and ordered him to get into the Fantastic Beast's suitcase so that he could take it into the underground vault. Lu Wei is too big to get in.

With Charon's command, Lu Wei snorted a few times, and finally reluctantly stuffed the three big heads into the suitcase one by one, and finally twisted his buttocks, and his entire huge body also got into it. Charon closed the box, held it in his hand, and said confidently: "Okay, with Lu Wei's help, we have some chance of winning!" ”

Harry, they are also in a much more down-to-earth mood, and with the help of the three-headed dog of hell, Lou Wei, they are also at ease.

The four of them walked towards the trapdoor. Charon bent down and pulled the tab on the trapdoor, and the door suddenly opened. He looked down, and it was pitch black below, and there was no ladder to go down.

"Or you stay here, and I'll go down and have a look." With that, he jumped straight down. Of course, Charon applied a levitation spell to himself before the jump, so that he could slowly fall like a feather.

Looking down, it was pitch black, bottomless.

Just as Charon was slowly falling, there was a violent wind sound from above, and it seemed that someone was really stupid and jumped straight down.

Charon hurriedly cast a vine binding technique, grabbed the man as he was about to pass by, and pulled him to see that the guy with a red face and closed eyes was Hermione.

Charon was surprised and delighted, and said angrily: "Why did you jump off like this? Didn't you say that you should wait on it? ”

Before Hermione could open her eyes to answer, Charon heard another eager wind from above, and it seemed that someone had jumped down again, and it was Harry who had been captured. And then Ron jumped down as well.

In this way, Charon dragged everyone down slowly, until finally landed on a soft thing. He didn't complain, and looked around in the dim light, as if everyone was sitting on some kind of plant.

"What is this?" Charon asked Hermione.

"I don't know, it seems to be a plant. Probably laid here to mitigate collisions in the event of a fall. Then Hermione suddenly screamed, it turned out that they had unknowingly been wrapped in long vines around their legs. 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!" Hermione shouted at them, "I know what this is—it's the Devil's Web!"

"Devil's Net, Devil's Net...... What did Professor Sprout say? Say it likes shade and dampness—"

"Then set it on fire!" Charon waved his wand, and a large cloud of fire erupted from the tip of the wand.

In just a few seconds, the vines immediately flinched away from the light and warmth, loosening their grip on them. The plants twisted, twitched, and automatically loosened the tendrils that were wrapped around them, and everyone finally broke free.

"I'm glad you listened so carefully in the herb class, Hermione." Charon said as he wiped the sweat from his face.

"Now you know, you can't do it alone!" Hermione said with some smugness.

"Maybe you're right," said Charon, who could no longer refuse them to venture with him, "but remember to listen to me, and hide behind me." If the opponent is the black-robed man, I am the only one here who can compete with him. ”

The three of them had to nod, in fact, they all knew that Charon's true strength was no less than those adult wizards, and he only had some basic spells, and his magic power was far worse.

"Let's go." Charon pointed to a stone corridor and said, "This is the only way to go." The three followed in turn.

It was extremely quiet, except for the sound of their own footsteps, the sound of water droplets dripping slowly down the walls. This corridor went down the slope for more than ten minutes, and there seemed to be a soft rustling and clanging sound in front of it.

"What sound?" Harry asked in a whisper.

"Could it be a ghost?" Ron was a little scared.

"Don't talk nonsense, I think it's like the sound of wings flapping." Charon retorted, "Look, there's a light ahead—I see something moving." ”

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

The room was now completely different from the last time Charon came, and there were countless small birds that were as bright as jewels, flapping their wings and flying 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.

"It's possible." Charon stared at the birds, "They look a little weird, so come on, follow me slowly." ”

Everyone was on guard and slowly moved over there, but there was no movement, and everyone easily came to the door, pulled the handle, and the door was locked.

Hermione came to her senses, took out her wand, and came directly to a lock-picking spell - the Alaho Cave Spell. Who knew that after the spell was cast, it had no effect.

What's going on? Charon also tried, and the situation was still the same. He turned his head to look at everyone, "It seems that this door lock is not an ordinary product, and the lock picking spell is ineffective, what should I do?"

"Why don't you just blow it up!" Ron had a bad idea.

"This ......" Charon hesitated, subconsciously he didn't think it was a good idea.

"Wait, these birds...... They can't just be used for decoration. Hermione suddenly figured out something.

"yes, these birds can't be meaningless!" Charon looked up intently at the birds flying overhead, shining—shining? It doesn't seem like it's a bird at all!

"Keys!" Several people shouted almost at the same time, "They are the keys!" Winged keys! ”

Charon immediately reached out for his broomstick, and so did Harry, and the two of them jumped to fly.

"Wait," Hermione stopped, "there are hundreds of keys up there, do you know which one?" ”

Charon and Harry looked at each other and shook their heads.

That was Ron's specialty, and he looked closely at the lock on the door.

"We're looking for a big, antique key — probably silver, shaped like a doorknob."

With a goal, it was easy to do, Harry soared into the sky, rushed into the dense group of key arrays, cast spells and fished a handful, grabbed them in his hand and checked them one by one. As the youngest Quidditch Seeker in a century, it's not for nothing. He also has a knack for searching for flying targets.

After a minute of weaving through the swirls of small, colorful wings, he noticed a large silver key dangling its wings, as if it had once been grabbed and crudely stuffed into the keyhole.

Harry drove with all his might, passing the key like a meteor, and by the time he opened his hand, it was already in his hand.

Ron and Hermione's cheers echoed through the high room. Harry landed, slipped the key into the keyhole, and twisted it hard. With a click, the lock popped open, and the key flew away again. It was caught twice in a row, and looked emaciated.

"Alright, get ready, let's go inside!" Charon grabbed the doorknob with his hand and pushed it open with all his might.

The second room was pitch black and nothing could be seen. But as soon as they stepped inside, the room suddenly became brightly lit, illuminating a shocking scene.

They stood on the edge of a huge chessboard, with black pieces in front of them, all taller than them, seemingly carved out of black stone or something. At the other end of the room, facing them, were white chess pieces.

Harry, Ron, and Hermione were startled—the towering white chess pieces had no facial features on their faces, and they looked a little scary.

"What now?" Charon asked.

"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?" Charon 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 have to come with you to get there?" The Black Knight nodded.

Ron turned back to everyone and said, "Need to think about it......"

"I'm afraid we'll have to replace the three black pieces here," he said......

Ron thought for a moment, and finally opened his mouth and said, "That's right, don't be angry, blame me for being rude, but to be honest, the three of you don't play chess very well-"

"We're not angry," said Charon, "and you're telling the truth, so let's do it, the three of us play pawns, and you command." ”

"All right, Harry, you take the place of the Bishop; Hermione, you stand next to him, in the place of that castle. Charon, you're going to be a knight. Ron said.

The chess pieces seemed to be listening to them, and as soon as he finished speaking, a knight, a bishop, and a castle turned around, turned their backs to the white pieces, and stepped out of the chessboard, leaving three empty seats for Charon, Harry, and Hermione.

"The rule of chess is that white moves first." Ron said, looking across the board, "yes...... You see......"

A white pawn moved forward two squares.

Ron began to command the black chess. The three of them silently obeyed his command.

It was only when another of their knights was eaten that they began to really feel the fear. The White Queen violently knocked the knight to the floor and dragged him off the board. He lay face down, motionless.
