Ever since Grindelwald came to Hogwarts to live in seclusion, Professor McGonagall's skull has been sore from time to time. She was worried that Grindelwald would run to the castle with his wand and "biu~biu~biu~" to the students, and then she was worried that a student would accidentally kill him and then evaporate from the world......

And she can't just drive people away, and she can't kill people with a knife. Because the European side wished that Grindelwald had just stayed in England and not returned to the European continent, and the British Ministry of Magic didn't want to create another powerful enemy before Voldemort could be disposed of.

So after thinking about it, she gave Zhang Xu a task, and she asked Zhang Xu to visit the lonely old man every one or two weeks to determine if the other party would pose a threat to Hogwarts.

When Professor McGonagall assigned Zhang Xu a task, she gave a good reason. First of all, Zhang Xu has an old relationship with the other party, and he can talk to the other party. Secondly, Professor McGonagall believes that Zhang Xu's ideas are similar to those of the other party, and he will not fight at the slightest disagreement. Third, even if the two fight, Zhang Zhouxuan can also deal with the other party for a while.

Zhang Xu was also worried that this bigwig, who was isolated from half the world, would magnify his moves one day if he couldn't think of it, so he took on this task.

Although Grindelwald is innumerable in European records, it is a demon that has brought great disasters to the European wizarding world. But after several contacts, Zhang found that this old man, who seemed to have become a bit talkative because few people had spoken to him for half a century, was really a genius. As for the disasters he single-handedly caused, how to deal with the fact that he is a European, Zhang is an outsider and it is difficult to say anything.

Since he opened the conversation box to Zhang, every Sunday has become a day when Zhang Xulei can't stop listening to the big guy's bragging.

And when the big guy is excited, he often demonstrates the spells he uses in the story on the spot, and then asks Zhang Xu if he wants to learn it.

Zhang Xu also learned a lot of spells because of this, and every time he went back, he sorted out what he had learned in the day, and relied on these spells to brush up his papers. Now he has a plan, which is to start writing a book called "Introduction to the Dark Arts in Europe".

What interests Zhang Xu the most is the history that Grindelwald tells in his mouth.

Although those historical stories have been put on parchment by an unknown number of people for half the world, and Grindelwald said that he does not know how many so-called writers he has supported to feed by studying him, no one has ever seen and written that period of history from his point of view.

At this time, Grindelwald was drinking snake soup while bragging to Zhang Xu about his escape from the U.S. Ministry of Magic.

"When 'I' was taken out of that cell, my name rang out in every corner of the prison." Grindelwald then said disdainfully, "The books say that the prison inmates were all cowering in the corners and shivering. ”

Zhang Xu, who was in a wheelchair, had in mind the image of Redi singing "The Internationale" when she was taken out of her cell in "Air Force One", which was just released a few months ago.

At this moment, the sound of someone collapsing on the snow as he walked was heard not far away. Grindelwald turned his head and glanced at it and ignored it, while Zhang Xu also looked in the direction where the voice came from and found that it was Fleur who came over with a basket.

"Why are you here?" Zhang Xu used Transfiguration to conjure a chair beside him, and then pulled Furong to sit down.

Then Zhang Xu introduced: "This is my fiancée, Fleur Delacul. ”

Fleur stood nervously beside Zhang Xu, and then bowed slightly to Grindelwald, "Hello, Your Excellency." I brought you lunch. ”

Grindelwald glanced at Fleur, who was tightly grasping Zhang Xu's arm, and said noncommittally, "Are you worried that he will stay with me, the notorious Dark Lord." ”

Fleur, who was told to break her mind, didn't know whether to nod her head or not.

After Zhang Xu disposed of the empty pots and bowls on the table in front of them, she placed a large plate of hot chicken sandwiches, beef patties, and a large pot of pumpkin juice on the table in front of her.

Then Grindelwald said thoughtfully: "I once heard that in France there was a girl who married a wizard. ”

"That's my grandmother." Fleur, who had just sat down, hurriedly stood up and said.

Grindelwald waved his hand, then pointed to Zhang Xu in the wheelchair and said, "You sit down, you see that he never stands up when he talks to me." ”

Zhang Xu pulled Furong to sit down, then took one of her hands and gently patted the back of her hand.

"France, I've been there many times." Grindelwald continued, "I've heard of the surname Delacour. ”

At this time, Zhang Xu found that Furong suddenly grabbed his hand hard, and he couldn't stop trembling with this power, and at the same time, he could also feel Furong's heartbeat accelerating.

Early this morning, Zhang Xu did not agree with Fleur coming to him, because he was worried that Grindelwald had the blood of Fleur's relatives on his hands. He could not care about the past, but he had to consider Fleur's feelings.

But he still didn't expect Fleur to follow because she was worried about herself.

As if not aware of the expression on Fleur's face, Grindelwald began to tell the story of how he had gathered his followers to speak at the Père Lachaise cemetery decades earlier.

Zhang Xu visited the Père Lachaise cemetery, where the musician Chopin, Eugène Bautier, the author of the lyrics of the Internationale, and other celebrities were buried, and the most famous is the wall of 147 soldiers of the Paris Commune who bravely resigned themselves chanting the slogan "Long live the Commune".

At the end of the story, Zhang Xu heard a name that surprised him.

"Who is Aurelius Dumbledore?" Zhang Xu asked in surprise, "Is he Dumbledore's relative?" ”

Grindelwald obviously didn't want to answer the question, and just waved his hand to signal Zhang Xu that they could leave.

More than ten minutes later, Zhang Xu and Furong returned to the dormitory of the castle.

After slamming herself into the soft couch, Fleur finally breathed a sigh of relief. When she looked at Zhang Xu next to her and wanted to say something to him, she found that he was concentrating on thinking about something.

"What are you thinking?" Fleur asked.

"I'm wondering about the identity of Aurelius Dumbledore." Zhang Xu replied, "I've never heard Dumbledore and Aberforth mention this person, and I thought there were only two of them left in the Dumbledore family. ”

At this time, Zhang, who had turned into a hula hoop above his neck, suddenly thought of a possibility.

Could that man be Dumbledore's mistake when he was younger?

Combined with the age of the person mentioned by Grindelwald, when he was born, Lao Deng's parents had already died and were in prison, but it happened to be not long after Lao Deng's sister died.

Could it be that Lao Deng borrowed alcohol to drown his sorrows when his sister died, Ah Deng broke up with Lao Deng and crooked the bridge of his nose, and Grindelwald escaped, and as a result, he got drunk and was plotted by his crush and then had an accident?

Afterwards, Lao Deng naturally would not accept the other party, and the woman was not accepted by the family after giving birth to a child out of wedlock, so she could only go to the United States.

Considering the location of Dumbledore's house, I can't figure out that the child's surname is Potter.

Zhang Xu was taken aback by his guess.

But after so many years, there are not a few people left who have died, and it is difficult for him to explore the truth behind it.

Furong saw that Zhang Xu was deep in thought again, so she said to him: "I was so nervous that the clothes behind my back were soaked with sweat just now, I'll go take a shower first." ”

Hearing Furong say this, Zhang Xu also remembered that he was also sweating profusely when he was learning the spell just now, and his clothes were already soaked.

But that's something that can be solved with a spell.

So Zhang Xu took out his wand and summoned the crutches with the flying spell, and then followed him into the bathroom of the dormitory with the crutches.
