Altar of the Heavens of Harry Potter

The treasure house of the mermaid family is located in the deepest part of the cave. Under Dumbledore's detailed guidance, Canaan found a bronze door in the tortuous cave within a short time.

The gate is engraved with golden magic lines, which seems to be inherited from the ancient magic circle system.

"Just open the door, the mirror space will not affect reality, and we don't have much time!" Canaan urged.

Dumbledore nodded, took out his curved bone wand, and cast several sharp spells one after another, blowing the bronze door to pieces.

Canaan and Dumbledore walked into the treasure house slowly after the dust cleared away with the water flow.

The space inside is only the size of a basketball court. Silver armor and weapons are neatly placed on the left side, and rows of blue crystal stone pillars are placed on the right side, with many items placed on them.

However, judging from the large number of magic lines carved on the crystal stone pillar, the items stored on the right are far more valuable than those on the left.

Dumbledore scanned the entire room and found that there was nothing he was looking for, then sighed and said: "It seems that the thing is lost!"

"What?" Canaan asked suspiciously.

"The crown of the mermaid tribe."

"Crown? Another crown?" Canaan muttered.

Dumbledore did not hear Canaan's words, and continued to explain: "The crown is the symbol of every generation of mermaid leaders, and it is also their weapon. With the power of the crown, they can easily control the water flow."

"Is there any characteristic of that crown?"

"Uh...I think, it seems to be inlaid with a blue gem the size of a thumb." Dumbledore recalled.

Sapphire?

"Oh, well, since it is the treasure of the mermaid tribe, let the mermaid tribe have a headache." Canaan stopped thinking about it, and then he came to the area on the right and carefully inspected the precious treasure on the crystal stone pillar.

Dumbledore also leaned forward, and he was also very interested in the treasures stored here.

The two looked at each other, showing a heart-to-heart smile.

"Do you have any recommendations? Which one is better." But feeling the little magic power left in his body, Canaan looked at the more than twenty crystal stone pillars in front of him again, and said helplessly.

There is not enough time left for him to check one by one.

"The emerald-colored green leaf seems to have been left over from the age of elves, and it contains a powerful breath of life. The water in the glass bottle is also very special, and it seems to be able to remove the curse of black magic. This crystal ball should be a shark. Human gems, which can isolate the waters..." Dumbledore seemed to know every treasure here, and it seemed that he had been peeping here for a long time.

"Very good, I want all the green leaves, glass bottles, and merman gems." Canaan looked proud.

"..."

Finally, Canaan and Dumbledore came out of the mirror space after confirming the items they picked.

"Ready." Canaan opened a space door on the stone wall above the treasure room, which can prevent water from flowing out of the space door and alarm the defensive magic circle inside.

Dumbledore received the instruction and flew his wand in his hand. Dozens of crystal stone pillars in front of him burst instantly, and the treasures stored on them were also wrapped in a transparent mask and flew towards Dumbledore.

"Go!" As soon as the voice fell, the figures of Canaan and Dumbledore had disappeared from the treasure room, and the golden sparks gradually disappeared.

There were only scattered crystal shards and some swaying water left on the spot.

 …

Hogwarts Castle Great Hall, dinner time.

The view overhead today is a vast blue sea,

The sound of rushing waves can be vaguely heard.

"Oh, Canaan, you really shouldn't miss the Charms class this afternoon. Professor Flitwick taught us the Levitation Charm. Alita was the first to levitate a feather, so she won 5 points for our college If you are here, I think we will get another 5 points." Roger said regretfully.

"I'm also very sorry." Canaan ate the food while cooperating with Roger, showing regret.

"Did you know that the freshman named George in Gryffindor didn't bring the cauldron this afternoon, and was deducted 10 points by Snape. Also, his brother Fred was caught by Filch while performing magic in the corridor." , another ten points deducted. There are these two freshmen in Gran style, I don’t think this year’s Academy Cup will be theirs.” Roger said excitedly.

"I think you should compare with Slytherin. They have defended the Academy Cup for several years." Alita interjected, she didn't like Roger talking about others behind his back.

"It's always good to have one less competitor." Roger argued, he always felt that Alita would target him.

Then he ignored Alita, turned his head to look at Canaan, and happily told all the interesting things that happened in school today.

At this time, Filch suddenly broke into the hall, his footsteps flustered, and he shouted in panic: "No, a large group of mermaids floated on the Black Lake, and they are going to attack Hogwarts! They are going to attack Hogwarts!" Here it is!" The sharp tone was like the voice of a male duck, very harsh and unpleasant.

"Shut up! Filch, don't make a fuss." Dumbledore frowned and stopped him in time.

"Everyone eat quietly, Professor McGonagall maintains order." After speaking, Dumbledore walked out alone.

"This guy is really timid, Dumbledore is here, who dares to attack Hogwarts." Roger muttered beside Canaan, it seemed that he was very convinced of Dumbledore.

Only Canaan looked at this scene and smiled, thinking that the mermaids had just discovered that their treasure house had been stolen, so they swam out of the water collectively.

Just don't know how Dumbledore will respond?

After a while, Dumbledore came back with a blank face. He sat on the rostrum and tapped the silver cup lightly.

"Ding ding——"

"The mermaid lost a golden crown inlaid with gems, so they rioted in the past two days."

"Fortunately, no little wizard was injured either yesterday or today. But I hope everyone can stay away from the Black Lake during this period to avoid unexpected conflicts."

"Finally, except for the deans of the four colleges who stay here to manage order, all other professors must come to the principal's office after dinner."

"Okay, let's continue eating."

Hearing Dumbledore's words, the young wizards in the audience immediately talked about it.

"Who is so bold that he dared to sneak into the mermaid tribe to steal the treasure." Roger said in surprise with a chicken leg in his mouth.

"Maybe it's hiding among us. The mermaids surrounded us yesterday." Terry interjected.

"I remember Will shot first, isn't it Will?" Roger looked at Will who had been eating food in silence. He always felt that this guy was very problematic.

"Shut up, I don't want to answer your question." Will gave Roger a hard look.

"I think you are suspicious. Hagrid has already said that they will not harm us. How dare you attack them first. You may be the accomplice of the dark wizard who stole the crown!" Will's attitude angered , Roger shouted, as if to attract everyone's attention.

"Say one more word, and I'll tear your mouth apart!" Will blushed and roared angrily.

"Damn it, come on..." Roger rolled up his sleeves.

"Quiet!" Canaan stopped in time, "Dumbledore will find out about this matter, you don't have to worry about it."
