Under the refraction of water light and the light of some fluorescent plants at the bottom of the lake, the whole mermaid village is surrounded by a green and faint light. Pen & Fun & Pavilion www.biquge.info

"Fluorescent flicker!" Evan waved his wand, emitting a brighter light.

The merfolk looked curiously at him and the glowing wand, but they didn't gather around, they were still singing and dancing.

Aven stepped closer and found that the crack was in the center of the mermaid statue's tail fin and waist......

It was covered with thick layers of aquatic weeds and moss, looming in the light of the wand.

Evan examined the gap closely, and it turned out to be formed after a piece of the scale on the statue had disappeared.

He plunged his wand deep into it, and his head followed suit.

Inside the gap is a narrow stone walkway, the size of which is only enough for one person to crawl through.

This road follows the topography and continues directly below the mermaid statue, which is a naturally formed crack.

There are no traces of man-made inside, and the rock walls on both sides look rough and rugged.

There seems to be something inside, but because of the angle, it can't really be seen from the outside.

Evan spat out a few bubbles, slung his wand across his chest, and stepped forward into the gap, slanting down.

With the glow of his wand, he took a closer look at the gray rocks on either side, and the texture was not as hard as he had imagined.

These rocks are easily damaged by external forces, and the cracks that naturally form inside are very narrow.

This means that without using the right magic to turn it on, it is almost impossible to rely on brute force to get in on the outside world.

The destructive power is slightly smaller, and it cannot open the outermost stone door of the statue.

If the damage is slightly greater, the cracks in the ground will collapse completely, annihilating the narrow corridor.

The scale is difficult to grasp, and the original designer must have made very careful calculations before building the mermaid statue on it.

In the gap, Evan swam diagonally down a dozen feet and landed on the ground with a slam.

The corridor formed by the gap disappeared, and the space in front of me suddenly opened up and became spacious.

The cold water and pressure around the lake quickly disappeared, and the air became dry again.

Evan turned around and stretched out his left palm to sense, and an invisible magical barrier crossed in front of him, isolating all the lake water.

Those merfolk outside can't use magic, how can this magic barrier appear here?!

Don't look at it as just an ordinary isolation of the lake, the magic barrier that suddenly appears is very powerful.

It must have been left by a powerful wizard, could it be Rowena Ravenclaw?!

In this kind of place, it seems that there is no one else but her!

No wonder the merfolk wouldn't come in, they must have known that they wouldn't swim far before they came out of the water.

Ai Wen quickly steamed the water droplets on his body and continued to move forward, feeling more and more curious in his heart.

He had only taken two steps before he stopped, and the mermaid song from above did not dissipate, but became clearer and clearer.

It sounds very ethereal and beautiful, like a heavenly sound.

The singing echoes in the corridor, making everything in front of you unreal, dreamlike.

"Something doesn't seem right with this sound...... Evan was stunned for a moment, his mind gradually lost in the mermaid's song.

The singing that rings in my ears has a seductive magic, and people can't help but immerse themselves in it and don't want to do anything.

In the beautiful music, Evan became more and more tired, less and less energetic, and just wanted to lie down and sleep......

"Shut your ears and listen!" he said to himself, his ears instantly filled with an unrecognizable buzz.

It's like the whole school in the auditorium talking noisily together, or whispering in class.

The mermaid's song returned, and the seductive power that had suddenly emerged from it disappeared.

Evan moved on, becoming more and more curious about the magic that remained here.

This magic relies on the activation of mermaids without any power, merging and influencing each other, and the design is very ingenious.

With Aiwen's current level, not to mention the involvement, there are many places that I still can't understand.

Along the passageway, he swirled down to a stone door with no handle or keyhole, only a shiny brown plank with an eagle-like bronze knocker on top, and a dark blue raven at the top.

Raven's eyes were eerily red, staring at Aven.

Evan pointed his wand at the raven above him and blinked his eyes before he realized that the ravens had two rubies in their eyes.

The glow of the wand shimmered in the light of the wand was uncomfortable to look at.

I don't know what material this guy is made of, it's very realistic.

In front of the door, Evan had the feeling of being watched, but uncharacteristically without any magical reaction.

He lowered his head, his gaze away from the raven, and onto the main body of the gate.

Looking at the familiar eagle-shaped knocker, Evan thought of the door to the common room at Ravenclaw School.

It is said that the current Ravenclaw Tower was once the laboratory of Rowena Ravenclaw.

That's why she left such a unique door there to test the wisdom of visitors and whether they are qualified to enter it.

Unlike the other three houses, which require passwords, only wizards who give the correct answers are allowed to enter Ravenclaw.

Even Ravenclaw students can only stay outside if they can't figure out the answer.

If it were another college, there would probably be many people sleeping in the hallways outside every day!

But the students at Ravenclaw College enjoyed it and thought it was a good test.

Since there is such a door here, there is no doubt that it must have been left by Ravenclaw.

Perhaps, her secret treasure key was inside, and Aven didn't expect it to be so simple.

Next, just unravel the questions raised by this door.

Except for the mermaid song with seductive power, he encountered no obstacles along the way.

Evan didn't let his guard down either, and since Gryffindor would leave a test to the table, there was no reason for Ravenclaw to do nothing.

He walked to the door with his wand in one hand and knocked lightly with the other.

In the silence, Evan felt that the sound was like the sound of a cannonball.

The hawk's beak opened at once, but instead of making a bird's call, he said in an indifferent, eerie voice, "Strange visitor, you will be judged here, and death will be your only destination." ”

As soon as it finished speaking, a powerful strange magic instantly filled the space around Aivan.

He instantly cast a prepared protective spell, but it didn't work.

The sudden appearance of the space around him was so powerful that Evan found himself under the influence of a petrification spell and lost control of his body.

At that moment, the ravens above the gate flew violently.

It chose above Aven's head, those blood-red eyes staring at him deadly.

This time, Evan could clearly feel death from the raven!
