The cold water of the lake poured into his features from all directions, and the surroundings were very quiet. Soon, he descended to a depth of twenty meters, the light disappeared, and there was darkness around him.

Under the pressure of the water, Hoffa's magic quickly began to transform into life to combat the massive pressure, but there was no other way for him to do it.

He held his breath as tiny bubbles spilled out of his mouth and nose, and the feeling of suffocation gradually took over his brain.

In the darkness, something touched his back and wrapped itself around his waist in an instant.

Then, a strong drag dragged him straight up.

Ten seconds later.

Hoffa, whose lungs were about to explode, burst out of the water.

Coughing violently.

The cold air made his hair freeze instantly, and he trembled and lay on the tail of Osivia's big snake, shaking his head vigorously in an attempt to shake off the cold.

The ice shatters quickly, and Ossivia is even faster in his half-snake state.

Finally, they were out of the dangerous crushing ice. Ossivia swam sideways onto the ice, then quickly dragged Hoffa to the unmelted ice.

Hofa shivered and climbed onto the ice, this was his first winter swim in his life, the temperature of more than 20 degrees below zero made his teeth tremble, and the difficulty was not enough for outsiders.

At this moment, in the center of the Black Lake, a large area of ice began to crumble and fall off. There is a faint mist rising from the surface of the lake, which looks similar to a hot spring.

"What, what the hell, this ...... This...... This ice surface ...... Collapse as you say. Hoffa's teeth chattered, he shivered from the cold, and no matter how strong his strength was, it seemed a little useless in the face of the natural cold.

Ossivia didn't answer, she quickly drew her wand and tapped it on Hoffa.

"Remove water and prevent moisture. ”

Soon, the water from Hoffa's body was sucked away by his wand, and his clothes and hair were drying again. He felt a lot better, but the energy lost by the drop in the core temperature of his body could not be compensated for in a moment.

Ossivia tapped herself again, and the frozen water on her body quickly evaporated.

She looked at the collapsed ice in the middle of the lake, her brow furrowed.

"How so?"

After a while, Hoffa eased up, he looked at the smoky water, turned over and inserted his hand into the lake, the temperature was about zero degrees, and the normal ice water temperature was supposed to not melt the ice that was half a meter thick.

"Are there geothermal springs in Scotland?" asked Hoffa.

"Not true. ”

Ossivia whispered, "Look at the edge of the ice. ”

Hoffa looked down and saw a fiery red line carved into the edge of the broken ice, which stretched all the way forward, but everywhere it stretched, the ice broke off.

"It's magic. Ossivia whispered.

"Who used it here?"

Hoffa was puzzled, looking at the scale of this ice break, one wizard could not complete it at all, at least dozens of wizards had to work together to do it.

"I don't know. ”

Ossivia drew her wand and lit the lake.

Cold air pooled from between her wands, and the lake quickly condensed into a long, transparent Xiaoice boat.

She held out her hand to Hoffa: "Let's go, whatever happens, let's go and find the library first." ”

After getting on the iceboat, Hoffa was still trembling for a while, and the core temperature of his body gradually rose. Fortunately, he ate something before he came, and he had some stock in his stomach.

Ossivia lit the iceboats, and they glided quickly and silently across the lake as the ice had fallen off.

Soon, Hoffa looked sideways, and the two of them were very far away from Hogwarts Castle at the moment, and when they looked back, there was only a vast mist behind them, and they couldn't see anything clearly.

Looking ahead, the island in the middle of the lake was also lost at this moment.

"Do you remember the directions?"

Hoffa asked Osvia, he knew that this senior sister did not have a strong sense of direction, and in such a dense fog, he was not sure if the other party could grasp the direction.

"I'm familiar with this piece. ”

After a pause, she added, "When I was at school, I would come to the Black Lagoon every night to swim. ”

Hoffa exhaled a puff of smoke, rubbed his hands, and didn't speak again.

Due to an inexplicable fall into the frozen lake, after boarding the boat, Hoffa's spiritual force field has been turned on.

After a while, he felt a group of creatures enter his perceptual range.

Looking down, there was something swimming in the black lake, and it was very hazy across the sparkling water.

One of the underwater creatures sensed Hoffa's mental force field, and it slowly swam out of the water.

Start with just a light white dot and gradually enlarge it. It became an S-shaped curve.

Approaching the surface, the creature silently flipped and turned into a backstroke. There was a sound of water, and a ** creature actually came out of the water.

She climbed onto the edge of the boat, slowly straightened up, revealing a charming girl's face, with water drops dripping from her face, lying on the edge of the boat and looking sideways at Hoffa, smiling.

Her brown hair was wet, her chest was hazy with tulle, her bare forearm joints had erected fins, and her collarbones were dotted with transparent scales.

In the darkness of the water, Hoffa could see a giant swinging fishtail.

It turned out to be a mermaid.

The scene is indescribably weird.

The mermaid climbed the iceboat and looked at herself without blinking.

Hoffa could see a hint of longing and temptation in the other's eyes, as if she was silently inviting herself to swim with her.

At this time, an inexplicable sense of familiarity came to his heart, and then Hoffa remembered, this seemed to be the little mermaid who wrapped his fingers around his fingers and sprayed water in his face when he entered the first grade.

How can it be so big?

"Are you ready?"

The mermaid asked in a low voice.

Hoffa barely heard as he rubbed his ears, "Ah, are you talking to me?"

Ossivia frowned at the mermaid and said coldly, "This is not the place you should be. ”

The mermaid's expression was a little frightened, and she looked at Hoffa and whispered, "Be careful." ”

With that, she turned her head and plunged underwater. The tail shook a few times and disappeared into Hoffa's mental force field.

Osivia: "The Scottish Lake Demon, a 4x-level magical creature." The lifespan is only 10 years, and when I was in school, I used to swim with them. Their saliva is the material of an aphrodisiac, and if you kiss it, you will be bewitched by it and dragged into the water. ”

"How do you know you've kissed?" asked Hoffa, muttering.

"No, only a wizard with a low spirit would be seduced by a mermaid. Moreover, they are not interested in female creatures. ”

Osivia paused and said with doubts: "Something is wrong, the lake demon will not haunt in winter, what happened?"

At this time, the lake narrows, and the shed ice gradually narrows into a waterway.

Hoffa, who had been nervous, saw some activity on the ice in the hazy mist.

He immediately tried to warn Ossivia, but the other man covered his mouth and motioned for him to keep quiet.

Hoffa covered his mouth and nose and could only stare at her.

Ossivia took out her wand and tapped her arm: "Disler Falcon." ”

Suddenly, she and Hoffa disappeared into thin air.

As the fog thinned, Ossivia stopped the iceboat.

They saw the shadows that were moving in the mist.

The creatures were half-human, half-fish, tall and burly.

It's the Lake Demon.

But it's very different from the girl lake demon I just saw.

Although these lake demons have the same body and fish tail, they are extremely ugly and hideous, but they are full of spikes all over their bodies. He also clutched some rusted but sharp anchors in his hands.

Some of them have curved and protruding spines, and they hold sticks with barnacles and algae in their hands, which they glide across the ice. Everywhere they crossed the ice, there were red lines carved into them.

The ice that fell off just now was actually the work of these creatures.

Unaware of the two intruders, Hoffa and Osivia, who carved red lines while communicating with each other in a completely unintelligible Lake Demon language.

Looking around, after the fog faded, the surrounding ice was actually full of male lake demons. There are at least several hundred.

Hoffa swallowed his saliva, feeling his lips a little dry.

He had almost never heard of it, and combined with the lake demon's warning to himself, he thought on his toes that these guys must be planning some unknown and dangerous plan.

The situation took a turn for the worse, and in the Black Lake, his combat power was at least ninety percent reduced, and he didn't have any transformation techniques that he could perform in the water.

Seeing that the fog was getting lighter and lighter, the lake demons would soon spot the two people on the iceboat.

Hoffa looked at Osivia, who shook her head, pointed to the ice in the distance, and then to the lake, and made a swimming pose.

Hoffa's eyes widened, he understood what Ossivia meant, she wanted to swim over.

Hoffa pointed to the boat.

Ossivia shook her head and pointed to her ear. Wave your hand.

What she meant was that the sound of the boat would attract the attention of those merfolk.

Hoffa gritted his teeth and nodded.

Ossivia didn't hesitate at all, and folded her hands under Hoffa's ribs.

Immediately, the iceboat under his feet turned into liquid.

The two of them fell silently into the Black Lake, and the endless cold swept through Hoffa's body again.

A meter below the water, Ossivia swung his snake's tail and dived with Hoffa, and the two of them rubbed the ice that kept falling off and entered the thick ice.

There was no sound in my ears, only the rumbling and dull sound of water.

The biting heat made Hoffa's brain almost ossify.

He felt that he would definitely have a psychological shadow on swimming in the future.

The madness of life is always beyond his expectations, one hour he was eating Christmas turkey in the school hall, and the next hour he was crossed and swam under the half-meter-thick ice of the Black Lagoon. Overhead is an indestructible block of ice, and beneath your feet, there is an unknown abyss with no light.

As long as Ossivia is careless, even if her body cramps, she and she will definitely die without a place to be buried.

Fortunately, the teacher of the Transfiguration class did not make any mistakes, and after about a minute, when Hoffa was holding her breath until she was about to choke on water, she covered Hoffa's mouth with one hand, and took out her wand with the other hand, drawing a circle on the ice above her head.

The ice circle is falling off.

Ossivia pushed Hoffa, and like a seal, he jumped out of the water and collapsed on the ice.

At this moment, Hoffa's face was pale and he was so cold that he couldn't speak. His teeth and bones rattled rattle.

He struggled to his feet, pressed against the ice, and began to do push-ups like crazy. While doing push-ups, he turned on the activated state. It constantly repairs the frozen cells in the body.

Ossivia crawled out of the ice cave, her condition not much better, her lips purple from the cold, her fingers trembling as she pinched her wand, and tapped it on herself, and then on Hoffa. Suck up the terrible ice water.

Then, she hugged her shoulder with one arm, and the fingers of her right hand drew a green magic circle in the air, and the magic circle was engraved with a large amount of information.

When she was done, she pressed it with one hand, and the magic circle spun and disappeared into the air.

Then, she stared intently at the thick moisture in the distance.

Half an hour later, Hoffa's brain regained consciousness, and the first thing he did was ask Osvia:

"What's going on, what are those lake demons doing?"

Ossivia shook her head: "I don't know, this situation is very strange, I notified the Aurors of the school, and told them to be fully vigilant, if something happens, someone will come to our aid immediately." ”

"Are the Aurors guarding the huntgrounds your men?" asked Hoffa, frowning.

"Some of my father's colleagues at Wizengamot, to be exact. ”

Ossivia stood up, "Without further ado, hurry up." ”

Osiva took Hoffa's arm, and the two of them stepped on the skate blades and quickly rushed towards the island in the middle of the lake.
