Close to the island in the middle of the lake, Hoffa felt a kind of magic.

These magical smells are quite complicated and incomplete. This magic wave is very similar to the wave he felt in the library at that time. If he could, he really wanted to stop and study the old magic of the school.

But now is not the time.

Osivia quickly set foot on the rocky beach of the island in the middle of the lake from the ice lake. She put away her ice skate and quickly restored her hair to her bun.

Then he took Hoffa by the arm and let him stand on the dark floodplain.

Under the dim night sky, the island is full of towering dead trees hugged by several people, among which you can see some open spaces under the trees without snow.

Is there a white stone tomb here?

Hoffa couldn't help guessing.

"Fluorescent flashing."

Osivia sang softly, and the light of the wand illuminated the surroundings.

Hoffa looked at his feet. Even after the snow had been cleared, the ground was covered with thick withered branches and leaves. No one had been to this place for hundreds of years.

They walked silently through the dead woods, surrounded by nothing but the creak of snow and the occasional crackle of broken branches. Around the branches and some towering rocks in the snow under the reflection, forming a strange appearance.

After crossing a hillside, a fuzzy building appeared on the hillside 100 meters away. Looking at the appearance, it should be a dark old church.

Osivia put down her wand and whispered, "I checked the information. This is where the headmaster of Hogwarts, who died before the goblin rebellion in 1612, was buried."

"I think we're crazy," Hoffa said, after looking at the old, dark land silently for a while

Osivia: "why."

"You can't come any time, but you can come at this time."

"There's a world war going on outside, and there's no time to waste. If you find the forbidden library ahead of time and destroy it, you can save hundreds of thousands of people.

"Will that make you feel better?" osivia whispered

"You think too much of my consciousness." Said Hoffa.

"You're not like me."

Quiet finish saying, osivia raised his wand a little bit, "fluorescent dance."

All of a sudden, the fluorescence at the top of her wand flew out, split in the air, and became one flashing white light spot after another.

Some white dots fly quietly into the old Scottish church, while others surround Hoffa and osivia, illuminating the dark island in the snow.

In the light of these flying lights, Hoffa saw the tombstone community beside the old church. The tombstones are large and small, and there are also some sculptures covered with snow.

The whole scene seems to have a strange romance.

"Let's check the tombstone."

Said osivia.

Olivia walked in front of her. Hoffa looked at her back and asked, "why do you know Hogwarts so well, an exchange student from demstrand and a Slytherin who has only studied in England for three years?"

"I just spend other people's time in exploring the unknown," osivia said

An irrefutable answer.

Standing in front of the tombstone, the snow was so deep that Hoffa had to open the broken grip to clear the snow at his feet.

After removing the snow, the tombstones show their bodies.

Hoffa squatted down, wiped a tombstone, and was shining in the flying light. Hoffa saw a line of blurry little characters on the tombstone: "Sam Beazley, 1210-1219. The rest of the writing was blurred.

Hoffa turned and asked, "is that it?"

"Here's his grin, showing his teeth as sharp as a razor.

"Ghordaqvambahlahbogh'iv?"

Lake demon language: "pe'el hutlhchohwi'wling."

Hoffa narrowed his eyes and his heart beat a little fast. He has seen magical creatures. Last year, he saw a lot of them, and even horsemen with the same intelligence as human beings.

But these creatures and centaurs are totally different things. Centaurs are calm and mysterious.

Although he didn't understand what these creatures were saying, he could feel a trace of barbarism and madness hidden in each other.

Osivia looked Alert: "can't you speak English?"

As soon as she said that, all the lake demons showed a look of sarcasm one after another, one by one clenched their weapons and became restless. But then the agitation subsided.

Those strong Lake demons separated slowly, and from behind came out a thin, rickety, old lake demon like skin and bones.

It stooped, holding a wooden staff about as high as its own, and the scales on its tail almost lost more than half.Osivia took another step and stood in front of Hoffa.

Seeing the moment of the lake demon, Hoffa felt a great crisis. This seemingly windless Lake demon contains a huge magic wave, even more than any wizard he has ever seen.

"Are you the chief?"

Asked osivia.

"What do you see?"

Asked the old lake demon.

"Nothing." Osivia smiles.

"Well, who are you?"

Old lake demon tail swimming, bared his mouth and asked: "students?"

It has sparse teeth in its mouth, but its tongue is pure black. When it speaks, the syllables contain the power of trance.

As soon as Hoffa bit the tip of his tongue, the back of his head turned upside down, and the cold sweat came down.

How could a humanoid be so terrible.

"We're here for a date, just hang out and get ready to leave the place," osivia said, holding Hoffa's hand

"Date?"

The old lake demon lost his smile.

"Your age, his age? Or do you think I'm blind

Hoffa's mental field shrinks to the extreme, and he can see the stone shaking at his feet. There are small lines on the surface when shaking.

Osivia did not speak.

"Old lake demon said with a smile:" you kiss him, I will let you go

Hoffa was staring at each other's ice blue eyes, which were only joking, just like a cat playing with a mouse.

Osivia released her hand and held Hoffa's face.

Hoffa was surprised. Is this guy serious?

But osivia just stuck to his right ear, his lips wriggling: "I'll hold it, you go back to school, find dipert."

Then she looked up and said, "I kiss you."

"The old lake demon tilted his head," interesting, teachers do this kind of thing to students, should be shut up Azkaban, Miss Romanov. "

As osivia's disguise faded, she drew out her magic wand and said, "what are you doing? Since you know I'm a teacher, how dare you stop me?"

"Teacher."

The lake demon shook his head, regretfully said: "this is our territory, you shouldn't break into here."

"When did this become your territory?" Osivia said cautiously, "this is Hogwarts territory, belongs to Hogwarts, and has always been."

"All the time?" The old lake demon smiles sarcastically:

"our race has lived here for tens of thousands of years. How long have you witches been here. How dare you, a witch with less hair, tell me all the time? "

As soon as his voice fell, all the lake demons behind him raised their weapons.

Osivia stepped back warily:

"what do you want to do? Your ancestors signed an agreement with the school. According to the agreement, the human like magical animals inhabited in Hogwarts shall not harm students and teachers. I think you understand this agreement

"Yes."

"But the agreement has changed and the times will change. It's not a coincidence that you're here."

Old lake demon cold side head said: "kill them."
