Eredin said nothing, just looked quietly at the pale man in front of him.

He was pondering the meaning of the man's words.

Hungry for knowledge and power?

"I can grant you the knowledge of magic." After a long while, he spoke slowly, "but white frost is just a natural phenomenon."

Crouch's eyes flashed with a shrewd look as he grasped those words: "Natural phenomenon?"

"I'll give it to you along with the magic book." Eredin waved his hand, "Now lead us to find Ciri's friends and children."

Crouch shook his head: "Not yet..."

Eredin's expression did not change.

The Wild Hunt drew their weapons.

The deformed black hound crawled in front of them, whimpering and growling, waiting for its masters' orders, and then it would pounce on the man in front of it without hesitation and tear him to pieces.

"Don't get so excited." Crouch waved his wand.

The white frost was strange, and as his wrist moved, it twisted slightly. It was so faint, so faint that it mixed with the wind and snow and was almost impossible to catch with the naked eye.

But everyone here saw it.

There was surprise in the eyes of the Wild Hunts.

Crouch tilted his head, looked at the man in the light curtain, and said softly: "You can't do anything about the white frost, but it seems we can try to use it."

He had this guess early on.

This group of creatures with pointy ears and suspected to be sub-humans do not seem to be able to master that mysterious magical power very well.

This is because of human prejudice against subhuman races.

Some of them are based on my own analysis.

The white frost was chased out from the portal, not by their own power. One could even see from their armor that it had magic and function to resist the white frost.

So he made a request to test the attitude of this group of people.

The result was exactly the same as what I had guessed.

They can only use it, not master it.

Eredin's expression didn't change much.

He looked at Crouch. "Magic?"

"Yes, our magic." Crouch waved his wand again, and the white frost was slightly affected again, and twisted a little. This was the best he could do now.

This level is insignificant.

There are also sorcerers in the Ain El clan who can do this, but...

That was the result of their clan's long years of research, and the young man in front of him had just come into contact with it.

Eredin met his gaze.

He tapped the table lightly, making crisp sounds. After a while, he slowly said, "You have convinced me, but at the same time, I hope you can prepare some magic information from your world for me."

"Of course," Crouch agreed.

Eredin waved his hand, and a team of Wild Hunt knights set off, carrying a large number of books, one after another, piling them up in this piece of ice and snow. The weight of magical knowledge was very heavy, whether it was knowledge itself or in its appearance as a book.

It is far too heavy for one person or even a few people to move.

Communication magic has no contact.

Eredin sat in a chair and looked at him quietly.

The Wild Hunt placed their hands on the hilts of their swords, ready at any moment.

Crouch raised his wand and uttered the spell in a clear voice: "Shrink quickly."

With a whoosh, the hundreds of books on the ground shrank immediately and became almost the size of green beans in the blink of an eye.

He opened a pocket.

He flicked his wand lightly and uttered the spell clearly: "Wingardium Leviosa."

One by one, the books flew into his pocket in an orderly manner.

Crouch hung it lightly around his waist, raised his head, and met Eredin's eyes: "How can I contact you? I don't have as much convenience as you in preparing books."

Eredin waved his hand.

A Wild Hunter handed over a small crystal ball, which was filled with dark grey mist.

"Speak a spell to him." Eredin said, teaching Crouch an ancient language.

The syllables are complex and difficult to understand.

Eredin didn't tell Crouch what that meant.

Crouch was also very cautious. He transformed into a parrot and waited for it to learn the sentence and not be affected before he started to learn it. After a few times, it could say it fluently.

"I hope we can have a pleasant cooperation." Eredin looked at him and spoke softly.

Crouch responded: "I also look forward to having a pleasant cooperation."

The Wild Hunt began to pack up their equipment, stepped into the portal, and then disappeared.

Crouch continued to collect the remaining hoarfrost until he felt that he could collect no more.

He also left quietly.

In Hogwarts, when winter comes, all the students prefer to stay in their warm dormitories. Of course, the little lions prefer to go out, especially on weekends. They are happy to go out and have a hearty snowball fight, but this year the fun is not that great.

The Slytherins were very well behaved.

They often have conflicts among themselves, but most of the time, they are resolved in the public lounge. The other three colleges can only see the little snakes with bruised faces and noses.

Although there were disagreements within the house, this year was their best performance in the past few years. From the beginning of the school year until Christmas was approaching and the end of the first half of the semester, the Slytherins had always been at the top of the house points, with Gryffindor and Ravenclaw lagging behind them by five points and fifteen points respectively.

This made Ron furious.

When did Gryffindor get suppressed by Slytherin?

Saturday is the day that little wizards look forward to most in winter.

Hogsmeade was waiting for them.

There was no potion research to be done and no tedious things to do in the castle, so Harry and the others naturally came out of the castle and sat in the Three Broomsticks pub.

"I think we should go to the Hog's Head together," Hermione said softly, taking a sip as Mrs. Rose brought over the butterbeer.

Ron frowned, "Hermione, I remember you were always very clean."

The Hog's Head Pub...

Ron had always been inclined to think that it should be renamed, and that the "Pigsty Pub" might be a better choice.

"No, don't forget the agreement between Harry and Professor Dumbledore." Hermione shook her head.

Harry had not told them about Dumbledore's past.

However, the discord between brothers cannot be concealed.

Including Harry's help in resolving the conflict between their brothers.

"Shall we go now?" Ron asked tentatively, drinking half a glass of butterbeer.

Hermione hesitated, looking at the floor which was so clean that it could reflect a person's face. "I think we should wait."

Harry chuckled and shook his head: "Professor Dumbledore's matter is not urgent. I'm contacting a key person recently. If I can convince him..."

He was referring to Grindelwald.

But the words are not finished yet.

The simple ring on the finger vibrated slightly.

"Someone has broken into the Forbidden Forest." Harry looked down and said softly.
