Since Zhang Xu began to devote himself to the construction of the maze with other professors, Furong did not spend the night in the castle in order to avoid suspicion.

Fortunately, Gabrielle came to wake him up every morning, otherwise Zhang Xu would feel that life had lost its color.

Although there is a dark tide outside the school, Hogwarts is calm and clear, everyone should go to class, prank to prank, and prepare for exams.

After Dumbledore led a raid on Voldemort last time, Voldemort in "swaddling" disappeared as if he had evaporated from the world, and no one knew where he and the Death Eaters had gone.

Zhang Xu suggested that Dumbledore go to Gaunt's Mansion and Riddle's Mansion, but Dumbledore did not find any traces of Voldemort's and Death Eaters' activities there.

In addition, Zhang Xu also paid for Dobby to go back to Malfoy's house for a run, but he didn't find anything.

Now Dobby has overdone it, as long as someone hires and pays him to do anything other than hurt Harry Potter.

One evening in early June, Zhang Xu had just returned from the labyrinth, and was about to go back to the common room of the Eagle Courtyard to review with everyone and prepare for the exams at the end of the month, when Dumbledore found him again.

Zhang Xu hadn't seen Dumbledore in the cafeteria for the past few days, and he didn't know where he had gone.

When Zhang Xu came to the door of the principal's office, he met Harry Potter, who was also called by Dumbledore.

After meeting Dumbledore in the office, Zhang Xu noticed that his mood was a little low.

"I've been seeing Gellert these days."

Dumbledore's first words silenced Zhang Xu, and Harry was stunned.

Zhang Xu now figured out why Dumbledore's mood was low, and the relationship between the two naturally understood, but it seemed that the meeting between the two was not pleasant.

Think about it, you haven't seen you for decades, but the other party came to you to ask about the other two young people, just like classmates and friends who haven't seen you for many years suddenly contacted you just to ask you to help give a thumbs up, and it is estimated that the other party did not give Lao Deng a good face.

So at this time, Zhang Xu was still silent.

"Gellert Grindelwald was the first Dark Lord and was known as 'one of the most dangerous Dark Wizards of all time.'" Zhang Xu explained in a low voice to Harry next to him, "Gellert Grindelwald and the Professor were friends when they were young, and then he went on the path of a dark wizard, and was finally defeated by the Professor fifty years ago. ”

After Zhang Xu's explanation, Harry remembered who Gellert Grindelwald was.

It's just that Harry has doubts in his mind about what Dumbledore is looking for Gellert Grindelwald.

Dumbledore waited for the two young men to finish muttering before continuing his speech.

"I asked Gellert about the dark magic that could restore Voldemort's body, and I think I've made a big gain."

Speaking of which, Zhang Xu and Harry both waited intently for Dumbledore to continue.

"A father's bones, unintentionally donated, can give your son a new life. The flesh of the servant, the donation of resources, can make your master reborn. The blood of your enemies, forced to give, can resurrect your enemies. ”

With every word Dumbledore spoke, Harry shuddered.

It's bone, flesh, and blood, and it's one thing to hear it in the kitchen, and it's another thing to hear it in the headmaster's office.

Gellert said that this was the best form of black magic to restore the flesh, and that all other magic had more or less flaws. I think that with Voldemort's character, he would have chosen this magic. Dumbledore continued.

Then, Dumbledore magically brought the Meditation Basin to the table.

"Before we get to this magical issue, I think we can watch a movie." Dumbledore said to Zhang Xu and Harry.

Next, Dumbledore took Zhang Xu and Harry to meet Voldemort's parents, uncle, and grandfather.

After getting to know the Voldemort family, Harry went into a state of stunned beauty.

Harry turned his head to look at Zhang Xu, who had a calm face, and asked curiously, "Zhang, aren't you surprised at all?" ”

Zhang Xu can't say that he watched the movie once in his last life, so he can only say: "A friend of mine who has forgotten his old age once said more than a hundred years ago, 'There is calm in every big event', and those who do great things must make Hogwarts Castle collapse before and the color remains the same, and Professor Snape washes his hair on the left without an instant eye." ”

Harry listened, and his expression was unbelievable.

Harry quickly came to his senses, and after figuring out a question, he said to Dumbledore: "Voldemort's restoration of the dark magic needs 'father's bones', and since we know who his father is, let's hide his father's bones first, so that Voldemort can't be resurrected?" ”

Zhang Xu and Dumbledore looked at Harry and nodded with "teachable" expressions.

Just when Zhang Xu thought that Dumbledore would say that he had hidden Voldemort's father's bones in advance, Old Deng said: "Unfortunately, when I arrived at the Riddle family cemetery this afternoon, I found that the bones of Old Riddle had been exhumed not long ago. ”

Zhang Xu was speechless, he knew that he would take the time to go to the grave over there to bury a thunder first.

"Then it's the 'blood of the enemy.'" Zhang Xu stared at Harry and said.

Seeing Zhang Xu staring at him, Harry immediately realized that Voldemort was now short of his own blood.

For the next few minutes, the three people in the office were thinking about their own problems, and the office fell into silence for a while.

Zhang Xu was thinking that it seemed to be a better option to plot against Voldemort through Harry's blood than to prevent Voldemort from taking Harry away, such as letting Harry's blood carry something strange first.

Don't think about viruses like the human immunodeficiency virus or hepatitis B virus, which are sensitive to heat and become inactive after boiling at 56°C for a while, and the latter after boiling water for two minutes.

Zhang Xu remembered that this magic was the magic of boiling, putting bones, flesh, blood, and Voldemort into a boiling potion to cook together, and these viruses were finished before the two-hole socket man came out of the pot.

And in this way, Harry is also finished, it is better to wipe his neck and then take it to cremation now.

Zhang Xu looked at Harry and couldn't help but think that if Harry was Harry, there wouldn't be so many things.

First of all, Hallie's aunt will think of her sister when she looks at her, and she will definitely raise her well.

Secondly, she will not be targeted by Snape everywhere.

The most important thing is that Voldemort doesn't have to deliberately plan to catch her to draw blood, Barty Crouch Jr. only needs to ask the house-elf to help, and he will not be able to get the blood she was forced to donate in the first month of school.
