Then they came to the edge of the Black Lake.

The winter of 1939 was really cold. The temperature was only about minus 20 degrees. It was so cold that Hoffa even missed the future greenhouse climate.

At the moment, the Black Lake has completely frozen, and the ice surface is as strong as hardened steel.

Standing on the edge of the frozen lake, Hoffa could see the bright white moon in the mountains in the distance. The whole world shows a kind of gloomy gray under the white moon.

When he read novels in his previous life, he didn't feel it. When he came to reality, Hoffa felt the vastness of the lake, which has an area of at least tens of kilometers.

"Where are those ancient people buried?" Hoffa asked.

"The island in the middle of the lake." "Do you know how to skate?" osivia asked, pointing to an almost invisible dot in the distance

"What?"

Hoffa was surprised.

"We can slide through."

"It's too slow," osivia said calmly

"Roller skating."

Hoffa said dryly.

Osivia stepped on the ice with her toes. Suddenly, a sharp ice skate appeared under her black leather boots. This makes her even taller.

See that ice skate, Hoffa help forehead.

"Well, I won't."

"I'll teach you that our speed will increase a lot if we learn."

Osivia squatted down involuntarily, and the wand touched Hoffa's feet.

The ice skate appeared at Hoffa's feet, and he immediately grew about one centimeter tall.

With another wave of osivia's magic wand, the snow on the surface of the lake scattered to both sides, leaking out the smooth ice.

She stepped on the ice and said to Hoffa.

"Come on."

Seeing how easy she was walking, Hoffa thought it would not be difficult, so he went up to the ice.

The next second, however, he fell to the ground, pushing his butt and face down to osivia's feet, as if he had stepped on soap when running in a bathhouse.

Osivia's lips twitched, and she said, "as a person of Oriental origin, your balance is too bad."

"I'm not Russian."

Hoffa sat on the ground and grabbed a snowball angrily.

"Russia?"

Osivia slid to the left and dodged the snowball very lightly. "What are you talking about. If strictly speaking, I am Ukrainian. "

"Is there a difference?" Hoffa got up. "It's all the Soviet Union."

He staggered and stepped on the ice skate to be careful.

This time, he swung again. He lost his balance. As soon as he stretched his legs, he was about to turn over. Osivia came quickly and grabbed Hoffa's arm.

"You don't seem to be good at anything but metamorphosis."

She weighed Hoffa with a scanning eye.

"Shut up."

Hoffa struggled to push aside osivia: "it's like you can learn to skate the first time..."

Dong!!

Hoffa, who took two steps, made a loud fall.

Ten minutes later, at the cost of more than ten consecutive falls, Hoffa, covered in snow, finally stood up and walked on the ice with no aesthetic feeling.

Osivia, on the other hand, pedals slowly beside him, leaving marks on the ice like a swan, her long black hair fluttering behind her head, and the white snow spreading under her feet.

She seems to be in a good mood today. Maybe it's because she found the clue. Maybe it's because it's interesting to watch Hoffa wrestling. Her words are a little more than usual.

"Can I help you?" She said, "I can hold you faster."

Hoffa: "you're helping me if you don't talk."

"I have a brother. You look like him."

Osivia said suddenly.

"Wow, it's a pleasure." Hoffa said.

"Stubborn, arrogant, but not bad in nature." Said osivia.

"He's in demstrand?" Hoffa asked, faltering.

"He's dead."

Hoffa almost fell to the ground.

"I'm sorry." Said Hoffa.

"It's OK. It's been a long time. I'm almost forgetting what he looks like."

Osivia's voice went down and returned to her usual coldness and seriousness.

The two skated further ahead, and Hoffa gradually became familiar with some ice skating skills and faster. He was finally able to straighten up a little.

"And your family?"

Seeing that osivia did not speak, Hoffa asked again, "except father and brother."

"And some distant uncles."

With these words, they are far away from the lake bank, and the outline of the Hogwarts tower is gradually blurred.

"What about your mother? Does she trust you to come to England?""When you die, when you give birth to my brother, don't ask irrelevant questions."

"Well."

Hoffa's unsophisticated ice skating skills became more and more proficient, and he was almost able to walk normally on the lake. But the light from the corner of his eye was always on osivia's face.

I noticed his eyes.

"Concentrate on your work." Osivia emphasized it.

At this time, behind a flash of light, a few seconds later, came a faint explosion.

Hoffa turned around and found that it was Hogwarts castle that began to set off Christmas Fireworks. Some colorful colors exploded in remote places, adding some colors to the white and gray world.

Hoffa thought for a moment, pointed behind him and said, "look, the snake shaped fireworks."

Osivia looked back and did not find the so-called snake shaped fireworks. These fireworks are ordinary spheres.

She said, "there's No... well."

As soon as he turned his head, Hoffa suddenly grabbed the ice and covered his face with snow. He said with a smile, "Merry Christmas, sister."

The snowflake faced osivia was stunned in the same place and became a big face. Even the whole bun was rubbed away by Hoffa for several times and scattered from her forehead.

Her expression twitched a few times, and then the dancing snow gathered into a ball in her hand. She hit Hoffa's face with a snowball and said calmly, "call me professor."

Hoffa touched the snow residue on his face and took a deep breath. The mental field controlled the snow around him and became a snowball, floating around him.

"No, only brilliant people can be honored as professors."

With that, he snapped his fingers, and dozens of snowballs flew toward osivia like lightning.

Osivia stepped on the ice and moved more than 20 meters to avoid the snowball.

However, Hoffa's mental field still manipulated the snowball and chased it like a missile.

Osivia smiles and shakes her head. "It's too weak."

With that, all the snowballs burst open in mid air and turned into snowflakes.

Hoffa's mental field was blocked by her, and then the dancing snowflake quickly turned into a huge snowball under her control.

"Er..."

Hoffa looked at the shaped snowball in the air, stumbled back several steps, and entered a state of meditation.

The snow around him trembled and spread, and gathered in front of him, forming a thick wall of snow in the blink of an eye.

Boom!!

A super large snowball with a diameter of nearly two meters hit the snow wall, forming an avalanche like super large snowdrift.

Hoffa laughs. The snowdrift seems to be alive. It turns into a fat snowman with a height of six meters and rushes to osivia.

Osivia narrowed her eyes, the legs of the fat Snowman suddenly broke off, tumbled to the ground and began to fall apart. She once again blocked Hoffa's metamorphosis.

Hoffa's hands closed, and the scattered snowmen soon became dozens of little snowmen the size of household elves.

One by one, they rolled up snowballs and smashed them at osivia.

However, the snowballs hit osivia's body and passed through without hindrance.

It's just an illusion.

"Ah, oh."

Hoffa, who found that he had hit the illusion, ran away, while the real osivia rushed over from the other side.

Hoffa made a sharp turn and began his escape on the ice. At the beginning, Hoffa's speed was barely able to keep a distance from osivia, but soon, he was caught up by osivia, who was not good at skating.

In high-speed taxiing, she firmly clasped Hoffa's shoulder. Standing on one leg, Hoffa was kicked in the calf with the other leg. Hoffa fell to the ground one by one, and osivia raised his eyebrows and released his hand.

But Hoffa quickly buckled her forearm.

Osivia's face changed.

Hoffa laughs, falls and drags her to the ground at the same time. They roll on the frozen lake several times before they can stop.

Hoffa was crushed on the snow.

Osivia sprang up, covered in snow, panting and puffing in the white fog, and pressing Hoffa's shoulder, she said, "you have to call me professor."

"That's not good, sister." Hoffa said with a smile, "you just won the skating, not the deformation."

At the moment, osivia's black hair was falling in a mess on Hoffa's face. She shook her head and said, "I didn't try my best."

"Neither do I. besides, I'm six years younger than you."

Hoffa tilted his head. "Were you better than me when you were twelve?"

Osivia was stunned, and then slowly shook his head: "I'm Animagus, who learned at the age of 13."

"Ha, that's all."

Hoffa sneezed. "By the way, your hair is in my nostrils."

"But so..."

osivia lifted her hair and stared at Hoffa, the pear vortex on her face gradually disappeared."Merry Christmas, Hoffa Bach."

"Well said, you always look depressed."

After a moment's silence, osivia got up straight, knelt down on the snow, looked into the distance and asked, "do you believe in ghosts?"

"Ghosts, do you mean ghosts? There are a lot of...

"in the last year." Osivia interrupted Hoffa,

"when I think of my family again. I sometimes even think that they are free from a lot of things. War, conspiracy, killing, sometimes I'm glad. When they left, there was no pain... "

" cough. " Hoffa had no idea what to do. He coughed twice.

"Er... I think... I'd better concentrate on my work"

click.

There was a strange click in my ear.

Let Hoffa side head a look, the ice side of the face somehow split a small grain.

AI...

Huo FA was stunned.

Then, one of the lines became two, two became four, four became eight, and the crackles spread like cobwebs, very fast.

After the mental field was swept, Hoffa lay on the ice and looked back at osivia: "sister, can you swim?"

"What?"

"This ice is only five centimeters thick," said Hoffa, pale

As soon as the words fell, the ice behind him suddenly broke completely.

Hoffa suddenly fell into the dark lake below.

The surging waves immediately engulfed his body. He couldn't swim and fell straight to the lake. It's more terrifying than ever.
