I was expelled from Hogwarts?

Rove narrowed his eyes and carefully examined the weird skull.

It seemed to be made of crystal, and under the candlelight, it shone with a crystal luster.

It's just that skull, with a wide and flat mouth, a long skull, a flattened top, a wider back of the head, and a row of sharp tusks... Obviously not a human skull, more like some kind of magical creature.

The flames burned fiercely, casting long shadows on the stone wall. Rove looked around and quickly scanned the entire room with the help of the light.

The room was empty, and a square hole was cut out in the wall in front of him, like a closet, where the skull was placed.

Looks like it's the item that Dumbledore asked Rove to take!

Just as the boy was about to reach out to pick up the skull, it suddenly opened its mouth, making a creaking and vibrating sound, and then, two blood-red human eyes suddenly appeared in the empty eye sockets.

The two eyes rolled around, and then slowly stopped after a while, and looked at Rove. The boy's scalp was numb, and he subconsciously took two steps back.

The skull stared at Rove, and said in a hoarse, smoky voice, "Where's Grindelwald?"

"Grindelwald is in Nurmengard." Rove stared at his head cautiously, and said, "It's not convenient for him to come here. I'm here to help him take you away."

"What's your relationship with Grindelwald?" Skull asked again.

Rove got into trouble for a while, should he say that he is a student of Grindelwald's ex-boyfriend... or the grandson of his ex-boyfriend's best friend?

After thinking for a while, he still said softly, "I am Dumbledore's student."

"Dumbledore?" Skull sneered, and said in a blunt voice: "Grindelwald is messing with that guy again?"

Rove didn't know whether the skull was describing a relationship or a certain action. He didn't answer, but asked instead:

"and who are you?"

"I am the Son of Scylla, the Undead, the Avenger, the Ruler and Guardian of the Island, the Immortal Dragon King..."

The skull said a series of names comparable to "Dragon Mother", and Rove only remembered Scylla.

"Son of Scylla?"

He remembered that Myrcella had said that the three mermaid sisters guarding the Fountain of Luck were named Parcelope, Siren, and... Scylla.

Rove raised his eyebrows and asked, "Do you know Parse Loper?"

"That's my mother's sister, a traitor." Skull shouted in a piercing voice, "You know her?"

"I don't know, but I've heard of it." Rove laughed and said, "You're from the island in the Fountain of Fortune, right? Why did you appear here?"

"Grindelwald brought me out." Skull said hoarsely, his voice dry and hoarse, "but this liar...he said he would help me avenge...but he left me here for decades."

The skull cursed Grindelwald full of resentment, Rove heard a little impatiently, and interrupted:

"Your mother is Scylla, who is your father?"

The skull suddenly shut up.

Rove narrowed his eyes, it couldn't be Grindelwald, right?

...

...

In the silent corridor, Karin waited anxiously for Rove with a lantern in her hand.

He entered the cell, opened another hole, and got in, but it had been a long time, and he didn't come out again. I don't know if there was any problem.

At this moment, in the cage on the left, an old voice suddenly sounded.

"Little girl, how about we make a deal?"

Karin turned her head and looked, and found a thin old man standing at the door of the cell, holding the fence with both hands. His face was gray and haggard, his cheeks were thin, his eye sockets were sunken, and his hair was gray.

"What deal?" Karin asked casually.

"I have gold in Gringotts." The old man grinned, showing his yellow teeth, "There are countless gold...I can give it to you...I will tell you where the key to the vault is..."

"As a trade, how about you give me a firefly lantern in your hand?"

"Is it really a lot of gold?" Karin deliberately showed a greedy expression.

"Indeed, there are a lot of them, and I can give them to you." The old man pressed his cheek against the fence, and bewitched, "The gold you can never use up in your life...you can enjoy happiness that you can't imagine."

"Then I want one million Galleons." Karin looked at him with a smile, "As long as you give it to me, I'll give you the lantern."

The old man's smile froze immediately, and then he said with a gloomy face, "Why don't you want a golden mountain?"

"Then I want a mountain of gold." Karin said with a smile, "You said that."

The old man's face immediately became gloomy, and he shouted: "You want to die... Since you have rejected my deal, let's die here together!"

He stared wide-eyed, chanted a spell, and a ball of purple light passed through the fence and shot out at a very fast speed.

Karin didn't expect the old man to cast spells without a wand. She didn't have a wand, so she could only back away.

But the curse was not aimed at her, but aimed at the two lanterns in her hand.

The purple light hit the lantern, and the glass cover shattered, and the two fireflies broke free and flew towards the sky.

The old man laughed out loud.

Inside the deep pit, there was a sudden low-pitched roar, accompanied by a sharp sound of piercing through the air, a huge tail twisted out a huge arc, and stabbed Karin fiercely.

Karin dodged to one side in embarrassment, and the door of the cell was instantly smashed to pieces.

The spiked tail shifted its target and flew towards the prisoner who was stunned by Rove. The sharp thorns pierced straight into his chest.

The prisoner was awakened by the pain, he screamed heart-piercingly, stretched out his hand to press the wound, his arm was soaked bright red.

The next second, the tail dragged the prisoner's body towards the pit, and the sound of manticore eating the corpse was heard later.

The sound of tearing and chewing made Karin's hair stand on end, her face became paler, so she had to go through the broken cell door and ran towards the room.

After the girl saw the hole opened by Rove, she got in with a sliding shovel.

Rove was communicating with the head when he heard shouts behind him. He turned his head and saw Karin's figure.

"What happened?"

"Those two lanterns were broken by a prisoner." Karin explained anxiously, "He can cast spells without a staff."

Rove gave a soft oh, then picked up the head, and said, "That's troublesome."

As soon as he finished speaking, he saw four or five fist-sized bulges bulging from the originally flat ground, and the top was like a fountain bubbling with soil, and little manticores drilled out.

The scorpion swarm was like a tide, quickly trapping Rove and Karin in the middle.

Looking at the group of manticores, Rove suddenly asked, "Karin, can you dance?"

"Huh?" Karin stared blankly at the boy.

"Come on, let me teach you a dance."

"..."
