"Mr. Scamander, you may come in!" Dumbledore called out from the headmaster's room as Rolf watched somewhat idly as the professors and students were busy.

I saw that the two bigwigs at this time were already sitting on the sofa peacefully, and on the surface, it seemed that nothing had happened, as for what the truth was, it was not for Rolf to investigate.

"Mr. Scamander, what if your grandfather found out what you were doing, I wonder what he would think?" Professor Dumbledore said with a pointed look at Grindelwald, and then pretended not to care.

"Professor......" Rolf instinctively prepared to state the reason he had just thought of outside the door, but Professor Dumbledore interrupted him:

"It's all right, Mr. Scamander, I've learned about your special abilities, you don't need to explain anything to me......" Professor Dumbledore said gently.

"Hmph, don't tell me you don't want to go to other worlds, what if you can find a way to resurrect your sister?" said Grindelwald with some sneer on the surface.

Professor Dumbledore was stunned for a moment, and unconsciously muttered, "How to resurrect Arianna?" and the entire Headmaster's office fell silent.

"What did you just tell the Professor?" Rolfe didn't disturb Professor Dumbledore's musings, but quietly approached Grindelwald and asked cautiously.

"It's nothing, it means that you have the ability to explore other worlds, and you want to trade my freedom for your protection. Grindelwald sat in his chair with a cynical expression.

Rolf really thanked him, this time he was more exposed, okay?!He didn't want to tell Professor Dumbledore that he could travel the world, okay?

It was a mistake to take him with you yourself!

"Maybe you're right......" Just as Rolfe was at war with heaven and man, thinking about how to explain it for a moment, Professor Dumbledore came back from his contemplation and broke the peace in his office.

He raised his dark blue eyes and stared straight at Rolf, and then said with some hesitation: "Mr. Scamander, I don't know what I can exchange for the opportunity to follow you to explore the other world?"

Rolf was directly startled by Professor Dumbledore's words, he didn't know what to say, and then Grindelwald hurriedly bumped him with his elbow:

"What are you doing? Dumbledore said he wanted to protect you from exploring the Atlas!" he seemed to want to get Rolf to agree so they could fight together again.

Rolf recovered from the shock Dumbledore had given him, and then said with some hesitation:

"Professor, it's not that I don't trust you, but I think a contract is still necessary, after all...... This is a guarantee from the gods. ”

In the end, he still couldn't give up the temptation from the big guy, and chose to accept Lao Deng to travel through other worlds with him, after all, a big guy like him is still very sure of his personal safety.

Otherwise, just like the last time I was in the camp of the Dream Witch, if it weren't for Grindelwald, maybe I would have been successfully attacked by Merry.

"Of course, I'm willing to sign the contract you said!" Dumbledore's eyes revealed a certain firmness, a far cry from the hesitation he had just had.

Rolf nodded after hearing this, and then took out a pencil from the half-plane with some excitement in his heart.

After all, after signing the wooden deed, old Deng Ke is his own person, won't he be able to walk sideways in the magic world in the future?

I saw a green light rise from the pencil, and then shoot in the direction of Professor Dumbledore with Rolfe's guidance.

When Dumbledore saw the light, he instinctively wanted to dodge, because his intuition told him that the light was not a good thing for him, but in the end, his body's instinct was controlled by the temptation of his resurrected sister.

When the green light entered Dumbledore's body, he hurriedly felt if something had changed in his body.

If Rolf knew what he thought, he would definitely persuade him, DUCK doesn't have to, after all, this is a magic technique, even if there is any harm, how can it be discovered by you~

After thinking about it, Rolf took out his book of knowledge, then removed the page of meditation, and then used his magic to control the page and fly towards Dumbledore.

Dumbledore instinctively tried to catch the paper with his hand again, but when his fingertips touched it, the page had turned into a little starlight and melted into his body.

"Professor, you can first cultivate the meditation method I taught you, which I also collected from another world.

If I'm about to explore another world, I'll contact you on my magic watch. With that, Rolf shook the dial on his wrist.

Professor Dumbledore sorted out the information that suddenly came to his mind, nodded, and then said, "Just let Gellert stay with me first, after all, ......"

Professor Dumbledore didn't say what he said next, but Rolf could guess that after all, a generation of Meguro Lords was by his side, and no matter who he was, he was not very relieved.

But Grindelwald didn't think so, he snorted coldly, but he didn't refuse, maybe staying by Dumbledore's side was what he wanted more?

Rolf nodded, and then walked out of the headmaster's office, after all, it was a little inhumane to disturb the reunion between the two after many years.

However, as soon as Rolf walked out of the principal's office, Professor McGonagall approached, first responding to Rolf's greeting and then knocking on the stone door of the office.

"Mr. Dumbledore, I think we need to talk about ending this semester early. Before he could get any farther, Rolf keenly heard Professor McGonagall's serious voice.

This is the first time Rolf has heard of the possibility of ending the semester so much earlier, after all, according to the normal time, it is just the end of the Christmas holidays.

And there is still more than half a year before the start of school next year!

It seems that the damage to Hogwarts Castle must have been so severe that it would take half a day to rebuild it.

So that night, the young wizards received an urgent notice that the young wizards of the wizarding family would go home through the Floo network tonight, and the young wizards of the Muggle family could only wait for the Hogwarts Express tomorrow.

It's just that there is one thing that has caused quite a stir, because this year's Defense Against the Dark Arts professor, Mr. Lupin, is about to resign from his professorship, and all the young wizards are not in a very good mood after hearing the news.

Harry, in particular, hurried to Sirius's office, wanting him to help him persuade Professor Lupin.
