Dumbledore looked at the three-headed and six-armed mermaid statue through his half-moon glasses, and he looked at it carefully for a long time, his blue eyes shining brightly.

"It's a statue of the merfolk sisters, Palselope, Siren, and Skulla." When Rove and Shirley discussed it privately, there was also such a speculation, but there was no evidence, so he asked in a low voice, "How do you see that?" ”

"Looks." Dumbledore waved his wand, and a large stone flew out of a wooden box and landed on his desk.

Rove noticed a brightly colored mural carved into the stone: a large hall with a two-tailed mermaid holding a scepter, and the lower part of the painting depicted a group of magical creatures of the sea, bowing to her.

Rove compared the mural of the two-tailed mermaid with the golden statue, and after a moment, pointed to one of the heads, and said, "She looks a lot like the mermaid in the mural." ”

"Yes, it's very similar, so I'm sure they're the same merfolk." Dumbledore said.

"Where did you get the mural?" Rove asked.

"The Golden Merfolk Tribe." Dumbledore held the teacup, twisted the rim of the cup with his fingers, smelled the refreshing aroma, as if the fragrance of tea could also make people intoxicated, and squinted, "It's the two-tailed mermaid I asked you to help treat last year, the family of the Messira." Rove was surprised, "So, she's Palmeroper?" ”

"That's right, the eldest of the three sisters, Palcellope." Dumbledore took a sip of tea and said, "She was in love with the ancient Greek wizard Odysseus, and left Avalon in order to chase him. ”

"The Golden Mermaid family is a descendant of Palmelope, so there are many murals of her, and this is one of them."

"So," Rove mused,

"The other two heads, Sirens and Skullah?"

"I think so, even though I haven't seen them." Dumbledore focused on the statue and looked down to see the mermaid's six hands: a cross, a chest, a sickle, and ...... Three torches.

The old man frowned slightly, "But I don't know what the meaning of the cross, the chest, the sickle, and the three torches are. ”

"Rove, I remember you said that Ravenclaw left you a secret room a thousand years ago, and since this statue was also left by her, maybe there is a Eucalyptus in it." Rove nodded, "I asked Helena, she knows the entrance to that secret room, and I'll take the time to go there." ”

"That's good." Dumbledore smiled.

"But when it comes to the meaning, I do know what the torch does." Rove said suddenly.

"Oh?" The old man made a deferential gesture.

"When Shirley and I found the statue, its torch was burning, and we reached out and touched the statue and it went into a fog." Rove said.

"Mist?" Dumbledore's eyes narrowed.

"There was a lot of fog, and in the fog you could still hear some people scolding, some people wailing and weeping." Rove recalled his experience in the Ravenclaw tomb and said slowly, "Shirley and I followed the sound and walked forward, and the fog quickly disappeared, and we actually appeared at Hogwarts, and met a wizard named Tertius. And he died not long ago. Dumbledore listened to the boy's words, and there was a deep amazement in his voice.

"Listening to your description, Rove, I think this statue has taken you and Shirley into the mystical realm of Tertius...... It's amazing that it still has this ability. Seeing the old man's shocked look, Rove wondered, "Haven't you ever entered the Blurry Illusion Realm before?" ”

"I've been there, but it's just my own fantasy, not someone else's." Dumbledore shook his head.

"How did you get in?" Rove asked curiously.

"Leaning on the Cloak of Invisibility."

"Cloak of invisibility?" Rove raised an eyebrow.

"Thirteen years ago, I found an invisibility cloak from James Potter." Dumbledore sat in his chair and gently answered the young man's inquiring gaze.

"The general invisibility cloak is a travel cloak woven from the hair of the illusion charm or the invisible beast, which can be invisible at first, but over time, it will gradually manifest itself."

"And Jaime's invisibility cloak is very old, and it is permanently valid, and it continues to be invisible." Knowing why, Rove whispered, "It's the Cloak of Invisibility in one of the Deathly Hallows?" ”

"That's right." Dumbledore nodded,

"I asked Jaime at the time, and he told me that the invisibility cloak had been passed down through generations in their family, starting with Iolans Peverell. Iolans was the only child of the Peverell family's generation, and she inherited the family's invisibility cloak without a brother. Eollans later married Hardwin Potter, and the Cloak of Invisibility was transferred from Peverell to the Potter family, where it was passed down from generation to generation. ”

And Eollans Peverell is the descendant of the third of the three brothers, Ingnotus Peverell. So I was sure that the cloak of invisibility was the Deathly Hallows! Dumbledore got up and paced slowly around the room.

"I don't really think much about the Cloak of Invisibility because I can be very invisible, and it won't work for me. But according to legend, a sorcerer who possesses three deathly artifacts at the same time is the true conqueror of death. So, I borrowed it and studied it for a while, and then I found that it ......" Rove looked at Dumbledore and muttered, "Can you enter the Blurry Illusion?" ”

"That's right, that invisibility cloak and this mermaid statue can enter the world of the dead." Dumbledore said with a serious expression: "But that invisibility cloak can only enter his own blurred illusion, far less than this statue, can shuttle to other people's blurred illusions, this ability is simply like ......" Dumbledore paused, exclaimed: "Death! Rove didn't speak, but pondered where Ravenclaw had gotten this treasure and why it was in his grave.

"Are you in Ravenclaw's tomb other than this statue?" Dumbledore asked.

"A golden apple tree, like Grindelwald's elderberry, from Avalon." Rove said softly: "There is also a wooden coffin with the symbol of the Deathly Hallows engraved on the lid. ”

"I've heard from my grandfather that he's seen a similar coffin in the Centaur tribe, have you seen it, Professor Dumbledore?"

"I haven't seen it, but I've heard of it." Dumbledore said calmly, "Actually, it is rumored that Hogwarts also has a wooden coffin like this. Rove looked up at the old man.

"It has been said by word of mouth that somewhere deep in Hogwarts Castle, there is a wooden coffin." Dumbledore said.

"This coffin is giving Hogwarts magic to keep it running on its own, so for thousands of years, the castle has never had an outside power." Rove was speechless in shock, if the legend was true...... Then this is already the fourth coffin.
