Ryder was discharged a week later. After he was discharged, he didn't talk to anyone about what happened on Halloween night.

There is a rumor that he beat up several good Gryffindor "little reporters" so hard that they were black and blue and couldn't walk.

Since then, no one has dared to ask him what happened on that night.

And Hoffa has nothing to do with Riedel, but these days, he has been studying the magic that can make people immune to magic, and he hopes to know what makes the half man King invincible.

But he checked for a long time and asked aglia, but he didn't get any information about the so-called magic immunity.

Time is gradually passing away in Hoffa's research and long study. Hoffa always wants to go back to Ravenclaw tower and get back his deformation script.

However, the school seems to be cruel, as long as one day does not catch the half king, one day will not open Ravenclaw tower.

This made Ravenclaw's students suffer a lot, because they have to wear clothes made for them by the school, and they have to use things made for them by the school.

The situation lasted until Christmas and didn't improve much.

At the dawn of Christmas, it was cold and snowy.

But at this time, the temporary rest room also shows some advantages, which is much warmer than the rest room on the tower. And because it's near the kitchen, it's easy to call a few house elves to add food for you.

Hoffa gets up very early every day. He drinks coffee from the house elf by the fireplace and reads "a hundred charms and a hundred Charms" borrowed from the library.

At eight o'clock in the morning, two of his friends came to Hoffa, yawning and carrying a carton.

Seeing that Hoffa was still reading, aglia threw the box in his hand to him: "God, you are still checking, Hoffa, I said more than a hundred times that no one can be immune to magic."

"Christmas present?"

Hoffa looked at the box in front of him.

"What do you say?"

"I'll take one of the 137 gifts I've received at random and give it to you. I hope it's not a box of slug fudge," said agraia

"I thought you would go home for the holiday." Said Hoffa.

"I don't want to go back, and I can't go back."

Agraia curled his mouth, "are you stupid to check the magic spell? The school issued a notice last week that Muggles have been playing hard outside. For safety reasons, all students will spend their holidays in Hogwarts this year."

"I see..."

Hoffa mumbled and opened the big box. Fortunately, it was not a slug candy, but a beautiful light blue men's scarf.

Miranda handed him a small box: "I don't expect you to give me any more presents."

"I'll make it up later." Hoffa whispered in a guilty voice.

He really didn't prepare gifts. He thought about the forbidden library and the Demi king every day. He didn't even pay much attention to the approaching Christmas.

"Mend a fart, you don't even know my birthday!" Said agraia fiercely.

"I don't even know my own birthday." Hoffa said with self mockery.

"It's pathetic."

Miranda laughs and pokes her wand into the fireplace. The fire is burning.

Hoffa opened Miranda's small box and found that Miranda had given him a hardcover book.

The shield mantra.

"Hum ~"

agraia's face suddenly turned clear, and she threw herself on the table in high spirits: "my birthday in July, or you two will come and play."

"It's too far away. Let's finish this year first."

Said Hoffa anxiously, turning over the book of shield mantras.

He still can't release the shield curse.

...

...

night, Christmas dinner.

The auditorium was magnificent. More than a dozen frosty Christmas trees were set up in the corridor, the top of which was covered with crisscross mistletoe and holly. There were also some golden owls that kept singing.

Although the outside world has been fighting hard, and although there are hidden dangers inside Hogwarts, it has not affected the progress of Christmas.

Hoffa came to the hall early, full of glittering plates and cups.

In the middle of the hall, there were several students pointing around the shining Hogwarts pearl. A few Gryffindors, a few days Ravenclaw.

Gryffindor probably did it out of curiosity. Ravenclaw probably did it to pray that he could return to the common room earlier.

But there is no doubt that for them, it is bound to be a day of disappointment.

There was no response from Baozhu.

Three people in a row sit down.

Before the party, Miranda suddenly poked Hoffa."Look."

She pointed to the entrance of the hall.

Following her fingers, Hoffa saw headmaster dipert.

Accompanied by the school doctor Lena, he went to the hall. He was much healthier than at the beginning of school. He sat on the classroom table and even had two glasses of fruit wine with Dumbledore.

This is something Hoffa has never seen before. In the impression of most students, the old headmaster seldom attended the banquet due to physical reasons. Basically, he only met at the school opening banquet.

After the banquet, President dipert made a few congratulatory remarks, and his voice was much louder than that at the beginning of school.

When he finished, Dumbledore, the vice principal, took the crowd to sing a Christmas Carol for a while.

Just from the beginning of the banquet to the end of the dessert, Hoffa saw that the position of the deformation teacher was always empty.

Osivia didn't come to the Christmas party.

Hoffa was not the only one who noticed it.

"Your boss didn't come." Agleia chewed the pudding and whispered, "are the people in the Soviet Union just Christmas?"

Miranda: "I heard socialism doesn't have Christmas."

"What boss." Hoffa was upset. "She's a teacher, I'm a TA."

"Cut..." aglia shrugged.

"I feel more like a partner." Miranda quipped, "Mr. John Watson."

Hoffa: "aha?"

"I don't see you being so interested in other subjects." Agraia curled her lips.

"What's in your head?" Hoffa knocked on each other's hairy silver head. "Do you think I really want to be a TA?"

Miranda restrained her smile and said seriously, "but Hoffa, I really think osivia's purpose is too strong. You can't be safe with her."

Hoffa said with a smile, "just like you did last year?"

Miranda got closer: "listen, a person with a strong purpose will not allow others to hinder him if... I mean, in case you have a conflict with her goal..."

"I know." Hoffa put down his knife and fork and interrupted Miranda. "I know this deformation teacher better than anyone else."

Miranda sighed, cut off a steak and put it in her mouth without saying any more.

Agraia was puzzled: "what are you talking about?"

As soon as her voice fell, a senior girl hurried up to Hoffa, bent down and handed him a note.

Miranda: yo

Agraia immediately poked his head over.

"It's strange."

Hoffa pushed away her hairy head and opened the note.

There was only one sentence on the note.

(to the hunting ground, I found the white stone tomb.)

It was osivia's letter. Hoffa immediately stood up and startled aglia: "what for?"

Hoffa: "take your time. I'll tell you when I get back."

With that, he put the note in his pocket and quickly walked out of the hall.

Miranda looked at Hoffa's back and said to agraia, "it seems that the letter from Holmes has arrived."

"What Sherlock Holmes?" Agraia frowned. "I seem to have heard it somewhere."

"Haven't you seen it?"

"What have you seen?"

...

...

Hoffa quickly left the laughing Christmas hall and walked out of the castle.

If osivia finds the white stone tomb, it means they are only one step away from the library of endless knowledge.

Just as he was about to walk out of the castle, Hoffa saw headmaster dipert, accompanied by school doctor Lena, walking slowly out of the hall from the corridor on the second floor.

He didn't ask Dr. Reiner to help him, but he seemed to walk unsteadily with no alcohol left.

Hoffa stopped, shook his head and watched for a moment, until the headmaster and the school doctor disappeared around the corner, he slowly walked out of the castle.

Through the mistletoe covered corridor, across the corridor of the Roman column, Hoffa saw the snow on the hunting ground reflecting the moonlight.

Osivia did not wear a wizard's robe. She was dressed in a black cape and hunting suit, standing on the white snow outside the castle.

She felt Hoffa's gaze and turned to look at him.

So Hoffa jumped over the marble fence and stepped on the ankle deep snow.

"Did you find it?"

"Well, let's go."

Osivia nodded to him and said briefly.

Deformation teacher walked in front, Hoffa followed her, and their boots creaked in the snow.

"What is the white stone tomb, at Hogwarts?" Hoffa asked with some urgency.

"Well, it should be."

"Well, how do I feel that you're not sure?""Absolutely not."

"But since the message is at the bottom of the first principal's stone statue, I think the white stone tomb should be the first principal's tomb," osivia said

"Did you find it or not?"

Osivia shook his head. "No, I didn't find any information about his grave."

Hoffa: Well... How do you say you found it

"I haven't found a specific location, but I've been looking up the information about the headmaster's burial site recently. Later, I found that all the headmasters of Hogwarts were buried on the island in the Black Lake after they died.

No matter who the first generation headmasters are, as one of the headmasters of Hogwarts, he must follow the tradition of Hogwarts, die at work and be buried at Hogwarts. "

"Is there such a rule?" Hoffa was surprised.

"Well."

"Where we're going tonight..." Hoffa asked in surprise. "The graves of Hogwarts' presidents?"

"That's right."

Osivia seemed quite calm.

Looking at her calm face, Hoffa felt as if he was crazy.

Instead of attending a party at school on Christmas night, I went to visit the tomb of the ancient headmaster.
