Ossivia stopped talking, and she stared at Hoffa without blinking.

Hoffa pointed to the black lake outside the floor-to-ceiling window and said, "I've always wondered why those lake demons cut the ice in the middle of winter, but now, I figured it out. The Black Lake is the key, the key to connecting the real and the unreal. ”

Ossivia turned her head, and she hurried back to her meditation position.

When Hoffa thought she was going to take the crown, she lifted the silver plate and shoved a sandwich into her mouth.

She had probably been hungry for a long time, and felt that eating like this was too inefficient. So he simply turned into a snake, opened his bloody mouth and swallowed all the food in one gulp.

Hofa looked at her and turned his head to support his forehead, almost unable to complain.

Then, she hooked the gold ring on the ground with her tail and swam to the small pool in her office, where she took on a human form.

"To the Black Lagoon?" she asked.

"That's right. ”

"Come with me. ”

Osylvia stepped directly into the pool and disappeared into it.

Hoffa cautiously walked to the pool in his office, looked at the lake outside the floor-to-ceiling window, and thought that this was probably a secret passage directly to the Black Lake.

He took a deep breath and stepped into the pool, and with a muffled rumble in his ears, he seemed to have entered an amusement park water skating. The body is hovering and bending, constantly falling.

After more than ten seconds, he tumbled into the black lake, like a weightless astronaut in space, surrounded by dark green water.

Fortunately, Osivia quickly swam over, grabbed his arm, swung his legs, and quickly swam upstream.

The lake was not much warmer in early spring than it had been at Christmas, and Hoffa pinched his nose with one hand and Ossivia's arm with the other. This was the year he swam the most, and the Slytherins were always inseparable from the water, which made it difficult for Hoffa, who was in the direction of the wind.

He is a Ravenclaw, loves the wind, and loves dry and cool places.

Ossivia emerged from the lake and stood with Hoffa on the slope of the Black Lake.

The wand drained the water from the body, under the bright white moon in early spring.

Hoffa pointed to the lake: "Look. ”

Ossivia looked at the lake, but found that the lake was so dark that even the reflection of the school did not exist. The entire surface of the lake, only the moon in the sky can be seen.

"School...... What about the shadow of the school?" Osylvia couldn't believe it.

"Herein lies the problem. ”

Huo Fa's tone was slightly excited: "There must be more than one place for the magic of ancient wizards, but if there is a mirror image anywhere, there is no place more suitable than here." ”

"But I don't know anything about how we're going to get there. ”

Hoffa pondered for a moment, and a long-ago encounter came to his mind, and he beckoned to Osivia.

"This way. ”

The two walked in the bright moonlight, and the dead branches that were exposed after the ice and snow melted were trampled by the two of them, making a crackling sound. In the moonlight of early spring, the shadows of the two pulled on the ground.

Eventually, they stood on a rocky floodplain far from the castle.

From here, you can see the station in the distance, and you can also see an old train waiting for the station to stop. It was a school bus, and the day after tomorrow all the students were going to leave the school.

Hoffa stood on the rocky floodplain, the moonlight was cold, and the stones on the ground seemed to be coated with a layer of white silver frost.

Looking at the dark surface of the lake, he whispered:

"I've been here before, and I came to this place on my first day on the train. I was here and saw the chassis of a speeding train, and my two friends said it was a dream, or maybe it was my hallucination.

Now that I think about it, it wasn't a hallucination, it wasn't a dream. ”

Osivia: "What the hell are you talking about?"

As soon as she finished speaking, there was a sudden sound of water on the lake in the distance, and a hazy figure emerged from the water and floated on the lake. Without blinking, he looked at Hoffa and beckoned to them.

Hoffa and Ossivia looked at each other, then slowly stepped on the rocky floodplain.

The cold water of the lake soon flooded Hoffa's feet, his knees, his waist, he stepped on the jagged pebbles, his palms flat on the lake, and stopped.

The figure in front of him was familiar to him, he had just seen it a month ago.

It is a lake demon with brown hair, a charming and soft face, a sparkling chest, and a huge fishtail underwater.

It's a maiden lake demon. As she had done last time, she had heard some kind of summoning and had come to Hoffa's side.

"Are you ready?"

She asked the same question this time.

But this time Hoffa understood what she meant, it was a vehicle similar to the Void Dolphin, and he asked, "Can you take me there?"

"Yes, but I need to be paid. ”

The lake demon floated on the surface of the lake and said in an ethereal voice.

"What's the pay?"

Osivia asked. "Do you want us to compliment you?"

The lake demon shook his head and looked at Hoffa quietly.

Hoffa: "Key, right?"

He took out the bracelet and coin.

"Wealth, fame, and one more thing. ”

The female lake demon said in an ethereal voice.

Ossivia took out the crown.

"Rights ......"

She stared at the crown for a moment without blinking, and her slender white arms were lifted from the water, placed them in front of Hoffa, and bowed her head as if she were waiting to be crowned queen.

Hoffa looked at the crown in Osivia's hand, took it, held it in both hands, and put it on the head of the lake demon.

Then, he grabbed her slender palm, placed Aglaia's bracelet on hers, and finally, placed the coin in her palm.

Under the dark moonlight, a silent ritual ended quietly.

The lake demon looked at the three things on her body and nodded in satisfaction, and then, she grabbed Hoffa with one hand and Ossivia with the other.

"Take a deep breath. She said.

"Wait a minute. Hoffa said.

"What's wrong?" the lake demon asked.

Hoffa looked at Ossivia solemnly.

"You were like a kamikaze last time, are you still that crazy this time?"

Ossivia was stunned for a moment, then pursed her lips, as if she was tasting something unusually bitter.

She didn't speak for a long time, so much so that the crowned lake demon frowned impatiently.

Hoffa: "Ossivia......?"

"Hoffa, I'm sorry for most of the year. I'm not a qualified friend, I have a terrible personality. And, I've hurt you more than once. ”

Ossivia raised his head and said seriously:

"But if I could, I wanted to be able to make amends. ”

Hoffa bent down and covered his mouth.

"Wow, you can say such sensational words, I'm going to vomit. He straightened up and stuck out his tongue at the lake demon.

"Take us away, I think maybe I need cold water to sober up. ”

The lake demon smiled and leaned back.

Immediately, both of them were pulled into the lake by her at the same time.

In the icy lake water, the huge tail of the lake demon swayed, and in the blink of an eye, it fell to a depth of dozens of meters, and the surrounding darkness and water pressure were so quiet and secretive.

With tiny bubbles on his lips, Hoffa looked at the dark abyss beneath him, but he uncharacteristically didn't feel much pressure.

He looked behind him and saw the lake demon's huge fishtail swinging in the water, above him.

Wait, is that from above?

Maybe not.

Hoffa's whole thing upside down, or rather, the world upside down.

At this moment, he was no longer diving, he was ascending, quickly and decisively.

There was a bright glimmer of light shining in front of him, a light in the darkness.

The light is constantly amplified.

Crash!

With a sound of water, the lake demon led the two of them out of the water and let go of his hand.

Hoffa looked around, stunned at what he saw.

The water here is not black, but a hazy white, and they can see the bright stars overhead. but they could not see the moon.

All around, there was a hazy water vapor, and the visibility was less than twenty meters.

Hoffa knew that he had arrived on another level of Hogwarts, the mirror world of the school.

"Be careful, he's back. After saying it softly, the lake demon turned around and made a huge splash with the tail of the fish, and disappeared into the crystal white lake at his feet.

Hoffa and Ossivia looked at each other, and the two slowly paddled forward, although Hoffa could not swim, but there was a strange magical force on the surface of the water that kept him from sinking.

After a while, his fingertips touched something hard, and when he looked at it, Hoffa found himself touching something hard, black, long, thick.

A straight railroad track.

It just crossed the water, coming from an unknown place and leading to an unknown distance, which was the railroad track that it saw in that inexplicable fantasy when it started school.

He touched the rails and glanced at Osivia.

The two climbed the railroad tracks and slowly climbed up. At this moment, Hoffa seemed to have returned to the moment when school started.

He stood on a huge mirrored surface, and in the ripples under his feet, there was a thick railroad track.

At this moment, neither of them spoke, and they slowly walked forward with solemn expressions.

Along the tracks, they soon saw a dark train car standing silently above the water.

Under the carriage, there was a shimmering white stone, which looked like milky crystals, white but heavy, and they formed a platform-like place one by one.

"Merlin's beard. ”

Ossivia sighed softly, "This thing was definitely not built by ancient wizards. ”

Hoffa didn't answer, he crossed his feet and looked into the carriage, which was empty and empty.

"Whew. ”

He breathed a sigh of relief and wiped his palms against the wizard's robes, his palms covered with sweat, and he pulled out his wand and withdrew his head.

Stepping out of the carriage, Osylvia patted him on the shoulder and pointed his finger into the distance.

"Hofa, look. ”

Following her fingers, Hoffa saw a row of black pressed lines in the misty vapor.

When they got closer, the two of them gasped, and he realized that it was not a line at all, but a dense group of people.

Black people.

These people were unclothed, unmoved and breathing.

With their heads bowed, they were a mass of structures with pure black metal on their bodies.

They fell on one knee on the white water, facing one direction as if on pilgrimage.

"Sure enough, hiding here, no wonder no one can find it at all. Hoffa muttered under his breath.

Ossivia grabbed Hoffa and stood in front of him: "Be careful. ”

The two of them remained vigilant for a long time, but the structures were as motionless as dead objects.

Hoffa looked in the direction of the pilgrimage to the structures, which was in the middle of the white lake.

A towering white island.

The two of them walked up the railroad tracks onto the gleaming white island, droplets of water falling from them automatically.

The island is not large, only about 30 square meters, and it is filled with milky white crystals, and there are four ten-meter-high statues around these crystals.

Hoffa recognized the statues at a glance.

Gryffindor with a sword in hand

Slytherin holding an orb

Hufflepuff with a staff

and, Ravenclaw, holding the scales

The four statues looked solemnly at the center of the island.

There, Hoffa saw a tall white platform, and underneath it were densely packed with scrolls of books.

Hoffa and Ossivia looked at each other, and she looked at Hoffa with a pale face.

With shocked looks, the two slowly approached.

Hoffa picked up a copy casually and looked at the name "Eternal Life: Bloodline Transformation".

When I opened the pages, I was greeted by a variety of arcane sharp red magic circles, and the whole book was written in russet Old English, the color was like dried blood. Hoffa touched the pages of the book, and the touch of his hands made him extremely uncomfortable.

Hoffa put down this one and picked up another book, Taboo and Demon Transformation.

As soon as he opened it, he saw a hideous man's face, he was all **, and the page described in detail the process of transforming the human body into a demon, and the content made Hofa's scalp tingle.

He put the book down and picked up another one.

Put it down again, pick it up again

Put it down, pick it up.

"Eternal Life: Split Soul", "Taboo: Shadow of Nightmares", "Taboo: Demon Summoning", "Reincarnation: Scourge of the Dead", "Reincarnation: Fog of Corruption", "Taboo: Spiritual Wandering", "Shadow: Funeral of the Living Witch", "Shadow: Shadows", .......

As he watched, he climbed up.

The entire hillside is densely packed with such secret techniques.

The more he looked, the paler Hofa became.

Eventually, he put down his book and stood on the top of the stone platform with Osivia, looking at the hundreds of forbidden spells beneath him, surrounded by a silence like stagnant water.

No doubt.

Forbidden Art Library.

Yes, there is.

This place is simply a paradise for dark wizards, and any book in it is enough to cause a violent shock in the modern wizarding world. How much ancient dark knowledge is sealed here?

"What about the Centaur King?" asked Ossivia in a weak voice.

At this moment, a gentle and hoarse voice came from behind them:

"The four founders want to destroy all these forbidden arts. They thought that this would put an end to the conflict between people. Naive idea, in fact, that conflict is the eternal melody of humanity. ”
