The merfolk treasure vault was located in the deepest part of the cave, and it didn't take long for Canaan to find a bronze door in the twisting cavern under Dumbledore's detailed guidance.

The gate is engraved with golden magic patterns, and it seems that it is also a magic array system inherited from ancient times.

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

Dumbledore nodded, took out his curved bone-catching wand, and blasted the bronze gate to pieces with several powerful spells.

When the dust cleared with the water, Canaan and Dumbledore walked into the treasure vault.

The space inside was only the size of a basketball court, with silver armor and weapons neatly arranged on the left side, and rows of blue crystal stone pillars on the right side, on which many items were placed.

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

Dumbledore scanned the room and saw that there wasn't anything he was looking for, then sighed and said, "It looks like it's missing!"

"What is it?" asked Canaan, confused.

"The crown of the merfolk. ”

"Crown? and crown again?" muttered Canaan.

Dumbledore didn't hear Canaan's words and continued to explain, "That crown is the symbol of each generation of merfolk leaders, and it's also their weapon. With the power of the crown, they can easily control the flow of water. ”

"Is there any characteristic of the crown?"

"Uh... When I think about it, it looks like a thumb-sized blue gemstone is set on it. Dumbledore recalled.

Blue gemstones?

"Oh, well, since it's the merfolk baby, let's give the merfolk a headache. Canaan didn't think much more, and then he went to the area on the right, carefully examining the precious treasures on the crystal pillars.

Dumbledore stepped forward as well, and he was also interested in the treasures stored here.

The two looked at each other and smiled heartily.

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

There wasn't enough time left for him to look at them one by one.

"That emerald green leaf seems to have been left over from the elven era, and it contains a powerful breath of life. The water in that glass bottle was also very special, and it seemed to remove the curse of black magic. This crystal ball is supposed to be a merman gem that can isolate the waters..."Dumbledore seemed to have a treasure for every treasure here, and it looked like he had been peeking at this place for a long time.

"Very good, I want green leaves, glass bottles, and mermaid gems. Canaan looked arrogant.

“......”

Eventually, Canaan and Dumbledore were sure of what they had picked before they came out of the mirror space.

"Ready. "Canaan opened a spatial door in the stone wall above the treasure room, which could prevent the water from flowing out of the spatial door and alarming the defensive magic array inside.

Dumbledore received the instructions, his wand flew in his hand, and dozens of crystal stone pillars in front of him exploded instantly, and the treasures stored on them were also wrapped in transparent light masks and flew towards Dumbledore.

"Let's go!" As soon as the words fell, the figures of Canaan and Dumbledore had already disappeared from the treasure room, and the golden sparks had gradually disappeared.

All that was left was scattered crystal shards and a still swaying stream of water.

......

Hogwarts Castle Hall, dinner time.

Today, the view overhead is a vast blue sea, and you can faintly hear the sound of the waves rushing.

"Oh, Canaan, you really shouldn't have missed this afternoon's Charms lesson, where Professor Flitwick taught us the Levitation Charm. Alita was the first to float the feathers, so she earned us a 5-point award for the house, and if you're here, I think we'll get another 5. Roger said with a look of regret.

"I also regret it. Canaan ate his food and cooperated with Roger with a look of regret.

"You know what? The Gryffindor freshman named George didn't bring a crucible this afternoon, and Snape deducted 10 points. and his brother Fred was also caught by Filch when he was casting a spell in the hallway, and he was deducted ten points. There are these two freshmen in the Grand style, and I don't think this year's House Cup will be theirs. Roger said excitedly.

"I think you should compare it to Slytherin, they've been defending the House Cup for years in a row. Alita chimed in, she didn't like Roger talking behind his back.

"It's always good to have one less competitor. Roger argued that 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 the school today.

At this moment, Filch suddenly burst into the hall, his steps were flustered, and he shouted in panic: "Oh no, there is a large group of merfolk floating above the Black Lake, they are going to attack Hogwarts!

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

"Everyone eats quietly, and Professor McGonagall keeps order. With that, Dumbledore walked out alone.

"This guy is really timid, Dumbledore is here, who would dare to attack Hogwarts. Roger muttered beside Canaan, looking like he was convinced of Dumbledore.

Only Canaan smiled at this scene, thinking that the merfolk had just discovered that their treasure trove had been stolen, so they swam out of the water en masse.

I just don't know how Dumbledore will respond?

After a while, Dumbledore walked back with a blank face, and he sat down on the podium and tapped the silver cup lightly.

"Ding-ding-"

"The merfolk have lost a golden crown encrusted with gems, which is why they have been rioting for the past two days. ”

"Luckily, neither yesterday nor today did any of the little wizards get hurt as a result. But I hope that everyone will be able to stay away from the Black Lake during this time, so that there will be no unexpected conflicts. ”

"In the end, except for the deans of the four faculties, who stayed here to manage the order, all the other professors had to come to the president's office after dinner. ”

"Alright, let's continue eating. ”

Hearing Dumbledore's words, the young wizards in the audience immediately discussed.

"Who is so bold as to sneak into the merfolk to steal the treasure. Roger said in amazement, holding a chicken leg in his mouth.

"Maybe it's in the midst of us, but the merfolk surrounded us yesterday. Terry chimed in.

"I remember Will struck first, wasn't Will?" Roger looked at Will, who had been eating his food silently. He always felt that this guy was very problematic.

"Shut up, I don't want to answer your question. Will glared at Roger fiercely.

"I think you're suspicious, Hagrid has already said that they won't hurt us, how dare you do it to them first. You may be an accomplice to the dark wizard who stole the crown!" Enraged by Will's attitude, Roger shouted, as if to draw everyone's attention.

"Say one more word, and I'll rip your mouth to pieces!" Will blushed and roared.

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

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