Ancient wizards return to Hogwarts.

"Is it really that powerful?" Astoria, who was sitting on her knees, also read the contents of the letter clearly and couldn't help but feel a little doubtful. After saying the words, she suddenly became alert and quickly reminded her sister not to try to use the brooch in the dormitory.

"I'm not stupid!" Daphne glared at Astoria.

"Yes, yes, so don't trigger it, we are under the lake!"

Daphne glared at her sister again, and at the same time couldn't help but recall the "photo" that Les showed her when he first took her into the secret room. In the video, the founder of the academy, Salazar Slytherin, fought a battle with the world-devouring serpent.

The reason why he was able to firmly gain the upper hand and finally kill Jörmungandr was because of his "field". And the brooch given by Les could actually summon that kind of thing?

Daphne didn't believe it and wanted to seize the time to try it in the secret room.

Seeing that her sister had received such a wonderful Christmas gift, Astoria quickly opened her own small package, and then also received a brooch.

This brooch is exactly the same as my sister's, except that the crystal on it is yellow. Likewise, this crystal also exudes a dangerous aura.

Astoria breathed a sigh of relief when she saw that she had one too. Although my sister received one more necklace than me, it didn't matter because it was considered "compensation". If her bracelet had been broken in Egypt, Astoria believed that she could harvest a bracelet today.

Likewise, Rice's advice to Astoria was to try it in the secret room.

How could two little girls resist this temptation? There was no time to open the remaining gifts, so the two of them put on their robes and shoes and hurried towards the Slytherin Chamber of Secrets.

After arriving in the secret room, the two looked at each other, and then Daphne said to let her go first.

"Okay." Astoria didn't show any pretense and flew directly into the air.

Daphne stood on the ground and injected a bit of her own magic power into the crystal brooch according to the instructions in the letter. The next second, an extremely strong fluctuation of magic power occurred in the drop-shaped amethyst.

Snapped!

The amethyst shattered into powder, and the water droplets inside splashed out. While flying in the air, the water droplets grew rapidly, and when they landed on the ground, they were already a large pool of water stains.

After that, Daphne witnessed the rapid expansion of the water stain, swallowing up all the magic in the surrounding air.

In order to avoid getting water on her feet, Daphne quickly flew into the air like her sister.

Under the watchful eyes of the two men, the puddle, which was originally only a little over one meter in diameter, occupied more than a third of the secret room hall in just a few minutes, and spread outward at an alarming speed.

"Sister, where is your crystal?"

Daphne's face darkened: "It's broken."

Astoria:?

Isn't this thing disposable? But how is this possible? If it was a one-time use, how could Les not remind them both, and how could he let them come to the secret room to try to use it?

"Try the restoration spell?" Astoria remembered a simple spell that Professor Flitwick taught them in class, which could be used to repair gadgets that were accidentally damaged.

Daphne pursed her lips. The crystal was shattered into powder, how could it be restored with a restoration spell? The recovery spell also has its limits!

However, with the mentality of giving it a try, she still tried to use the recovery spell on the brooch, but it had no effect.

Both sisters were silent now, Daphne felt her breathing getting faster, and Astoria was secretly glad that her sister had tried first.

"Let's talk to Les when we get back to the lounge," Astoria suggested.

"Yeah." Daphne nodded helplessly, and that was all she could do.

But the thought of telling Les that the Christmas gift he gave her was ruined before she even warmed it made her feel extremely bad.

The two of them stared down at the expanding water in an awkward atmosphere. After watching for a while, Astoria suddenly frowned: she felt that the water below her seemed "alive".

It is "eating" as if it is alive, and what becomes its food is the magic in the surrounding air. By continuously devouring magic power, its size is gradually expanding.

A strange thought came to Astoria's mind: If she allowed it to be swallowed up, would this body of water eventually cover the entire world? Or is it that, just like humans, it has a limit to its size and will stop growing after it reaches a certain level?

She wanted to observe.

In order to verify her previous inference, Astoria pulled out her wand and used a "Thunderbolt Explosion" on the water on the floor. The explosion spell hit the water and caused a splash.

Astoria raised her eyebrows: this spell was much less powerful than she thought.

Daphne was startled by her sister's actions and when asked what she was doing, Astoria told her sister her suspicions and speculations.

Now Daphne also narrowed her eyes: listening to her sister's description, she also felt that the water under her feet was alive.

Eh? She suddenly remembered the scene in the first grade when the mysterious young man fought against Quirrell who was possessed by Voldemort. The swamp created by the young man at that time also seemed to have this characteristic. Could it be that this is what these weird gadgets have in common? By extension, if you can make something have such characteristics, can you also conjure such a thing?

In Daphne's mind, she was 90% sure that the young man back then was Les, so the swamp and the water below her now were all caused by Les.

Why would he give himself such a brooch? Do you want to inspire yourself to understand this magic?

While Daphne was thinking wildly, Astoria continued her experiments. She was already certain that the water beneath her was swallowing the magic contained in her spell. However, because the area growth rate did not change significantly, she was not sure whether her magic power helped the water area expand.

She thought it was a big deal.

Astoria activated her bracelet and fired an attack magic towards the ground. This time the spell penetrated the water and shattered several floor tiles.

"Be careful of Les getting too anxious with you," Daphne said in a teasing tone.

"I will compensate." Astoria responded to her sister absentmindedly. She noticed that after releasing the attack magic, the speed of the water's expansion suddenly accelerated.

"This body of water can swallow magic power," Astoria said with certainty, "Including the magic power in the curse, it is assimilating everything!"

"Then should we go find Les? Otherwise this thing will eventually get completely out of control." Daphne also became worried, she was afraid that the water area would expand indefinitely.
