The song was deep and ethereal, as if seeping out of the paintings on the rock wall, reaching into the depths of the soul.

But William knew that the singing was real, not his auditory hallucinations.

Soon, the toad crossed the rock wall, and in all directions appeared a number of rough stone dwellings, which were stained with algae.

As more and more dwellings are made, the singing is becoming clearer and clearer, and it is as grand as heaven.

William and Hermione sat on the couch, looking out at the deep black lake, and a very strange scene appeared in front of them.

The place seemed to be the square of the merfolk village, surrounded by houses, and in front of the square was a large school of merfolk.

They are singing in unison, their tails striking the stones as accompaniment.

It's hard to imagine that such an ugly-looking mermaid can make such a beautiful singing voice.

In the middle of the many mermaids, stands a statue: a beautiful mermaid carved out of a boulder.

The statue looked exactly like the mermaid on the rock wall.

Under the leadership of the merfolk patriarch, all the merfolk bowed to the statue.

It turned out that they were not singing, but praying.

More precisely, these merfolk were carrying out sacrifices.

The mermaid patriarch raised the trident in his hand high, and the silver trident was as bright as a bright moon.

Thousands of mermaids are scattered from the inside to the outside, and their tails are slightly floating in turn, shining with golden light under the light of the trident, as if they are in a myth.

William looked up suddenly, and he didn't know when a huge whirlpool had formed above the Black Lake.

A head poked out of the center of the whirlpool, and his gaze fell straight on the trident, his eyes cold.

William only felt ridiculous at this moment, although he could see the other party, he felt that the woman and him were not in the same latitude, let alone in the same time and space.

This feeling is getting stronger and stronger.

Moreover, that woman is definitely not a mermaid on the rock wall, she is a witch!

Because she slowly floated from the whirlpool, and she actually held a wand in her hand.

Like a ghost, she floated around the square, and as far as her body went, the light of the mermaid's tail became more dazzling, and the gold gradually turned to white, white as day.

William was dumbfounded, he wanted Mercury to leave quickly, it was not safe to look here.

At this moment, the Ravenclaw bronze ring hanging on his chest suddenly became extremely hot.

The next scene caught William off guard, the witch stood in front of the statue, hooked her hand slightly, and the ring floated from him, slowly floating in the air.

The witch smiled slightly, and said something in her mouth, but the two sides were not in the same time and space, and she said that William couldn't hear anything, and the witch couldn't get the ring.

The witch sighed slightly, waved her hand in annoyance, and the ring returned to William's hand.

William held the bronze ring, and his thumb subconsciously rubbed the pattern on the ring.

The witch frowned and turned her back to him, as if out of sight and out of mind.

William looked at the other party's back, and then looked down at the ring, and seemed to understand a little, dare to be annoyed that he rubbed the ring?

It's another Robert, and this ring is not anyone's wife...... Ravenclaw can touch it, but he Stark can't touch it?

"And, the ring is mine now! Do you have what it takes to hit me? ”

William relied on the other party's inability to hear, and began to live a mouthful of addiction.

Hermione looked at William in confusion, not knowing what he was thinking.

She looked at the ring in William's hand, and also frowned and pondered. Today's scene was beyond her expectations, even more shocking than when she first learned about the wizarding world.

After all, after being at Hogwarts for so long, she thought she knew the wizarding world well, but now there was another layer of fog.

The witch ignored the ring and waved her wand in her hand.

The light on everyone's fish's tail was all pulled away, and in an instant it left the ground, flew up, and hovered over the witch's chest.

In the light, the witch shines brightly!

Her wand flicked, and two-thirds of the light melted into her, and a third rushed into the sky, exploding near the whirlpool, meteors.

The witch swept up in the air, her robe floating, took a deep look at William, and disappeared into the whirlpool again.

With the witch gone, the coercion in the sky gradually disappeared. Only then did all the merfolk dare to open their eyes, and the dim light on their tails was completely extinguished.

The merfolk were all very sluggish, only the light of the trident became stronger and stronger, but the light flowed for a moment, and gradually disappeared into the halberd.

The mermaid patriarch stood up and saw William and the others on the periphery of the square at a glance.

At this moment, the toad was transparent, and the mermaid patriarch could clearly see William.

The old mermaid seemed to recognize him as yesterday's foursome, and it pulled up its trident and motioned for the people to close the door and let the dog catch him!

The so-called dog is Grindillo, a magical creature that has mostly been domesticated as a pet by mermaids.

Needless to say, Mercury directly urged the toad to continue swimming quickly towards the depths of the Black Lake.

In front of it was a field of turquoise aquatic grass, several feet deep, much like a very dense forest.

As long as they hide in it, the other party will not be able to catch them.

At this moment, without the slightest defense, the toad was grabbed by something.

Countless Grindy Lowe, leaning out of the aquatic weeds, their long nails gripping the toad tightly, their long sharp fangs sticking out of their mouths, trying to bite it.

Mercury manipulated the toad to open its mouth, not knowing how Lemay used alchemy to transform it, the toad actually spit out a stun spell, and countless red rays of light scattered and shot out, smashing on Grindillo.

The toad leaped high again, about to move away from the mermaid village.

Seeing that William was about to escape, the vengeful merfolk patriarch swung his trident again.

Within the Black Lake, the Trident was already very powerful, and because of tonight's sacrifice, this weapon was even more powerful.

The invisible magic power swung away, and the toad was obviously floating in the water, but it seemed to be in mid-air, and fell directly.

No matter how much Mercury tried to control it, the fall momentum was still unstoppable, and after falling nearly ten meters, it slammed into the bottom of the lake, stirring up the surrounding mud.

At this time, in the Slytherin common room, Professor Snape was wearing a mask and directing the group of young wizards who were about to leave the school to clean up.

The Hogwarts train departs at eleven o'clock, and it's only ten o'clock, so it's still early, just in time to clean the Slytherin Lounge.

"Hurry up, clean this fireplace, and you're good to go." Snape said impatiently.

Snape, who had a serious cleanliness fetish, always felt that the young wizards were not very clean.

At this moment, a deafening clatter suddenly sounded from the skylight of the dome.

The sound was as if a boulder had smashed into the black lake and fell to the bottom!

The whole lounge was shaking!

At this moment, the young wizards, including the dean, Professor Snape, all raised their heads, like fish swarmed at the bottom of the lake, looking up at the rippling black lake.

Could it be that a meteorite fell to the bottom of the lake?

Wait a minute...... That glass...... It won't break, right?
