Due to its proximity to Hogwarts, no wizard would go into the nearby waters to collect magical materials, which was not allowed. Pen % fun % Pavilion www.biquge.info

The merfolk themselves are not well-versed in magic and potions, so they are even less likely to be interested in these things.

After thousands of years of accumulation, the amount of various materials and herbs in the nearby waters has accumulated to a terrifying number.

Two months ago, when Evan gave the merfolk his first gift, they were overjoyed and had planned to trade the graffiti, pebbles, shells, and all sorts of messy things for the decorations.

In the end, Ewen could only reluctantly accept the magic materials and herbs that a few merfolk had taken out.

The merfolk were worried, worried that they wouldn't be able to find the right thing to exchange with Aven,

Compared to human wizards, their village is too barren by any means......

Seeing that Evan was willing to accept these things, they felt that they had finally found the right direction.

The merfolk began to gather these magical materials and trade them with Aven.

Over time, the news spread more and more.

The number of mermaids who knew the news grew more and more, and it evolved into the scene it is today.

You know, although the merfolk look extremely scary on the outside, they are not actually evil dark creatures.

They are also not as arrogant as the centaurs, do not communicate with humans, and only live in small circles of their own clan.

On the contrary, the mermaid is very open-minded and friendly.

They are in awe and yearning for magic, willing to make friends with human wizards, and even more fond of human-made objects.

It's a pity that there are few wizards who can speak the language of merfolk and are willing to come into contact with them, and wizards who can communicate with them will not do the same as Aven.

Aside from him, no wizard would exchange items for magic materials to meet the needs of the merfolk.

At this moment, a strange picture appeared under the lake.

A large group of merfolk surrounded Aivan, and precious magical materials were delivered as if they were not worth money.

Since today it is a mermaid tribe and a sacrificial event, the number of mermaids who flock to the festival is much larger than usual.

They floated around Aven, their eyes wide yellow and their mutilated teeth in their mouths yellow.

Each of the merfolk looked at Aven, trying to show a terrible smile on their faces that they thought they had good intentions, but that looked ill-intentioned.

Of all the items that Evan had brought, the mirror was their favorite, and they were robbed like crazy!

Anyway, this result is a bit unexpected!

Evan wasn't sure if the merfolk would be scared to tears when they saw their ugly faces in the mirror.

After a few words of greeting, he irresponsibly threw down the items all over the ground and left them to the merfolk to choose.

Anyway, they are very trustworthy, and will consciously leave the magic materials used for exchange in place and wait for Evan to come and collect them.

Evan walked to the middle of the plaza and found the strong merfolk he had seen for the first time in a magical stun.

After a few contacts, he knew that the other party had a high status in the merfolk tribe, and was a very powerful warrior and respected.

Ai Wen handed over the gift he had selected for the other party, and the mermaid whispered a few words, probably to express his gratitude to Ai Wen, and asked Ai Wen to go to his house to get the corresponding magic materials after the sacrifice was over.

"What's this ritual you're doing?!" Evan asked directly, spitting out a large pile of bubbles.

"Just the traditional celebrations......" the mermaid said in a hoarse, deep voice.

He also spat out a bunch of bubbles in his mouth, and the mermaid spoke quickly, and there were many things that Evan still didn't understand.

But the general meaning is clear, this kind of sacrifice is left by the mermaid ancestors, and it is carried out once a month.

Much to Aven's intrigument, he was told that there were rumors that the sacrifice was originally an agreement between the mermaid ancestors and the castle builders.

Over time, the sacrifice evolved into the event of remembering ancestors and large gatherings in the tribe today.

In other words, it's likely to have something to do with the treasure key that Ravenclaw left behind.

Evan was immediately interested, and after chatting with the other party for a few words, he waited for the event to begin.

After more than an hour, more and more mermaids emerged from all directions, and the number reached more than five hundred.

Many of them do not live in this lake, but in other waters near Hogwarts.

Even in the central lake of the centaur tribe, there are traces of mermaid activity.

They came from all directions, and many of the merfolk looked at Evan curiously.

They pointed at him and whispered with their hands over their mouths.

The things that Evan brought with him were sold out more than forty minutes ago.

A variety of magical materials and herbs filled his body with two cloth sacs that had been extended by the Traceless Stretching Charm.

There were a large number of mermaids floating in the square of the mermaid village, and when the festival began, a very strange scene appeared in front of Aiwen's eyes.

The merfolk swam slowly in a circle, and some of the merfolk began to sing in unison.

The voice sounds strange, but it is very pleasant to the ear, completely different from the usual voice of the mermaid.

Even the language seemed to be different, and Ewen couldn't understand it, but this beautiful singing voice was the voice he remembered the mermaid singing.

They danced and sang around the square, and despite the icy depths of the lake, the atmosphere grew louder and hotter.

The so-called ancient festival now looks like a grand celebration.

The merfolk let Evan join them, and they slowly danced forward in a special trajectory.

Directly in front of the square, stands a crude statue: a mermaid carved out of a boulder.

When the ritual reached its peak, Evan noticed that a strange wave of magic began to appear throughout the space.

There is no magic in the merfolk themselves or their singing, and Evan has confirmed it!

But the singers seem to be able to resonate with the giant mermaid statue and cast a strange magic, one that only a mermaid can use.

Although not very powerful, the rumbling sound resounded incessantly inside the statue.

Evan stopped, looking warily at the massive statue.

"Don't worry!" said a mermaid next to him with a smile as he continued the dance.

After a while, a deep gap appeared in the position of the tail under the mermaid statue, as if the door had been opened, and the lake water quickly poured in.

The merfolk didn't enter, still dancing to welcome them, but signaled for Evan to enter.

Evan hesitated, swam near the gap, and looked inside through the light outside......
