A large hole was broken into the wall of the prison chamber in Newmont Gaardburg at this moment.

The moonlight shines in, but it is far less bright than the dark blue light inside the house.

Grindelwald stared at the flamingo outside the castle.

This is a very strange bird. Its body is silver-white, as bright as the moonlight, and looks like a patron saint. But its delicate head, slender neck feathers, back and wings are covered with deep blue flames, and the flames keep jumping. Its eyes are exactly the same as Grindelwald.

"Go and bring my wand back, and we have a lot to do after that." He said calmly.

The firebirds passed through the dark night and flew into the distance. Grindelwald took a few steps outside and the air blew in. He approached the black wall and stood on the edge of the tower in Newmont Gaardburg.

At the very far away where the sky meets the ground, it transitions from pure black to dark blue.

Grindelwald lowered his head and stared at his left hand.

The talismans in his body are extremely stubborn and cannot be solved in a short time, otherwise he would not have been trapped here for decades. Previously, he burned most of the talismans in his body with blue flames, but there were still a small part of them that were difficult to eradicate. Grindelwald could clearly sense that they were everywhere in his body, devouring the magic that he had finally recovered and controlled. If he didn't do anything, they would grow stronger again soon.

The sky gradually became brighter. He had to make a decision as soon as possible.

Grindelwald looked back at the corner of the prison room, there was nothing to hesitate, and now was the best opportunity. Dumbledore - or someone else, should have appeared to stop him as soon as he tried to break free from the imprisonment, but nothing was there.

Oh, he just broke the wall by the way. The magic on the wall has nothing to do with Dumbledore, but maybe the International Federation of Wizards can get news.

The magic power in his body gathered on his left hand, and his body became empty, and then the tiny spells seemed to be attracted, pouring into his left hand, gathering together along the way, becoming complete, but Grindelwald let all this happen.

Finally, the remaining spell fragments were pinched together, and they were flexibly and greedily chasing the magic power that devoured his left hand, and these spells shone brightly, and every minute and every second became more complete. At this moment, Grindelwald seemed to feel something - through the spell - he vaguely saw a vague shadow.

The man seemed to notice it, raised his head, his face was blurred, but his light blue eyes were impressive.

Grindelwald's heart sank, and the last bit of hope was lost, and he brought up a cruel smile.

"Peng!"

The violent black fire burned violently, crackling, burning his flesh and blood while completely destroying the last spell. After doing all this, he was already sweating and trembling all over.

But it was all worth it—a new power emerged, a new magic without spell pollution was born from the depths of his soul, and perfectly merged with his body that was almost exhausted at this moment.

He was reborn.

...

Hogwarts.

Felix glanced out the window and blinked in confusion. He seemed to have seen the old man Grindelwald just now. Is it an illusion? Or the new ability brought by the talisman? But he was obviously a little short of controlling the talisman... His heart sank, there would be nothing wrong, right?

Half an hour later, Felix appeared in Newmont Gaardburg.

This was the first time he came here, not very adapted to the smell of humid air and rotten straw, and there was a burnt smell mixed in the air. He carefully checked the big hole in the wall, and there was an extra line of black handwriting: It was all for greater good.

He had a headache. After a while, more than a dozen figures fell from the sky outside the castle. Felix retreated and hid in the dark. He did not want to meet these law enforcement officers for the time being. After coming out of Newmongaardburg, he went around several nearby towns, and the spell on his arm had no reaction at all.

Felix was dazed at his arm. Isn't this thing useless?

He just got it.

When Felix returned to school, it was already bright, and the school was no different from usual, with some early-awaited students eating at the dining table. He found Professor McGonagall, who knew that she was even more excited when she saw her, and pulled him to the staff lounge without saying a word.

"Ajinbad received a letter from an owl this morning, and then his face changed drastically. He hurriedly left without even having breakfast." She said first.

Felix asked thoughtfully, “Did he say why?”

"No. But his expression seemed very panicked, it must be a very important thing." Professor McGonagall guessed.

"Oh, Grindelwald ran away last night."

Professor McGonagall stared wide and she seemed very excited.

"Felix... are you talking about Gellert Grindelwald?" Her voice trembled. Felix suddenly realized that she had experienced Grindelwald's most active era and had a clear influence on him. Felix told the general story, including the information that Grindelwald had disguised his identity and taught in school.

Professor McGonagall sucked the whole time, grabbed the clothes on his chest tightly, and his body was shaking.

"I didn't expect it! He turned out to be Professor Basharat, Ming-" She paused, her eyes flashed with memories, as if she had found evidence from her past interactions with Grindelwald, such as his superb magical knowledge and hostile attitude towards Muggles.

Professor McGonagall tried to calm down, "Albus—why did this?"

"I think it's because of a prophecy." Felix said softly, reaching out to show her the image of the anti-wizard parade. "A year ago, Grindelwald escaped from Newmont Gaardburg and came to England. He obtained his exclusive wand at Future World Company in Diagon Alley - the qualification review was not as strict as it is now - and then, perhaps he saw the recruitment information in the newspaper, so he used the picture you see now as a condition to teach in school for one year."

"...The current president of the International Wizards Federation, Aba Jinde, also knew about this. They sent someone to check Grindelwald's physical condition last summer vacation and confirmed that he was still bound by magic, and his magic was polluted and his strength was not as strong as before. Finally, they agreed to this approach."

The actual situation is of course more complicated.

Felix still doesn't know whether Dumbledore's promise of this condition was the superiority or whether emotion gained the upper hand, but in short, there was a new professor of Black Magic Defense in the school.

According to Felix's judgment, Dumbledore may have been under a lot of pressure - I believe that the people from the International Wizards' Federation would not mind coaxing Grindelwald, and then kick him back to the cold, damp and dark prison. Grindelwald certainly knew this, so he found Dumbledore as a guarantee.

"The transfer process happened last night?" Professor McGonagall asked keenly.

"Yes, Dumbledore has a way to monitor Grindelwald's status, probably similar to a double-sided mirror..." Felix briefly explained the principle that both imprisonment magic and surveillance keys are the same. "I guess he might not have thought of transferring the spell to others when he improved this magic, so there was a loophole. Of course, this point is hard to say clearly. If Dumbledore had not mastered this key, Grindelwald might have escaped from prison in his first few years..."

The process of transferring the secret key of the talisman only cuts off the connection with Grindelwald, but does not invalidate the imprisonment magic, so Felix's words are very credible.

"Okay, I roughly understand." Professor McGonagall slowly accepted this reality. She had been glad that the school was safe this year. Unexpectedly, it was turbulent in secret. She worked with the dark wizard Grindelwald for a year without any notice. She even made a lot of reports to Dumbledore...

“So no one knows where Grindelwald is now?”

"I didn't find him in Newmont Gaardburg, but," Felix hesitated for a moment, remembering the handwriting he saw on the wall, and shook his head, "He wouldn't be content to hide. I'm concerned about another problem-"

"What's the problem?" Professor McGonagall asked painfully, rubbing his forehead.

Felix smashed two boxes of letters on her desk, "We should place these letters in categories. To be honest, there are a lot of them, and there are only two of us, so we can't find help."

"Why find a helper?" Professor McGonagall glanced at him, put on his framed glasses, as if he was ready to complete the work assigned by the former principal conscientiously before officially becoming the principal.

Felix felt a little uneasy.

He was not sure if the letters would come in handy, because Grindelwald probably guessed Dumbledore's death. The question was, would he expose the illusion that Dumbledore was still alive? This question hovered in his mind when he came out of Newmont Gaardburg, and he did something for this - nearly one-fifth of the letters in the box were written to Grindelwald, and Felix left the letters.

They were busy with this matter until noon.

Grindelwald can't find anyone now, I don't know where he is hiding it. Maybe he is to take care of his body. Felix has seen how weak Dumbledore's body is after transferring the talisman. Of course, Grindelwald cannot be intact. Even if he has a few more strength left at this moment, he has to say hello.

If it were him, Felix would definitely find a picturesque place to cultivate his body secretly. After a few years, he believed that his strength would be more mature and time would be on his side.

"Oh, by the way, Voldemort died last night. He had to survive with some evil black magic before, and could only imprison him in secret. But all this came to an end last night, and he had died completely and forever."

During the break of work, Felix announced a major news calmly.

...

In the school hospital, Felix said almost the same thing to Harry.

After learning that Dumbledore's body was properly placed, Harry still felt very nervous. When he thought of Principal Dumbledore lying alone in the coffin, even death itself became a secret and was not known to outsiders, his heart was twisted.

"He deserves a grand funeral, not a corner of burial in silence," Harry said, staring at the white sheets on the hospital bed, a stain there. He thought of Regulus Black, who now knew that Regulus had fought against the darkness alone, but how long would it take for anyone to know the sacrifice Dumbledore made?

"What happened now is what Dumbledore wanted to see." Felix said lowering his eyes.

After a while, they talked about other issues.

"Professor Hepp-You mean Ba, Grindelwald recovered his consciousness during the transfer? How did he do it?" Harry asked in surprise.

"I will remember to ask this question next time I see him." Felix dragged his chin and said in confusion, staring at Valen and putting a bunch of candy into a smiling face. Harry stared at the pattern listlessly and was stunned. He had a flash of inspiration and thought of Neville's glass.

Although he and Hermione couldn't find any problems, maybe the professor could find doubts in it?

He told the professor about his guess, but the professor's reaction was mediocre.

"The mirror is bad. There is no doubt that there are only a few of the dozen magic script circuits that are correct, but the problem is that as long as an error occurs, the mirror as a whole will not work, and it cannot even be alerted..." Felix said, his voice slowing down.

"Professor? Did you think of anything?" Harry asked with his breath.

"If this is the case, then this thought would be too clever." Felix murmured, his eyes brightening, and he thought of a possibility - in fact, there are better ways, but not as open as this - taking advantage of people's psychological blind spots.

The spectacle in Neville's hand may have played a role.

It is not to remind Neville that the hair belonging to Grindelwald, which belongs to Grindelwald, together with the incomplete magic circles, forms the positioning part of another mirror.

Felix himself introduced seven different types of viewing glasses in class. One of them is that when the viewing glass is close to the owner of the hair, it will issue an early warning. This kind of viewing glass is generally only used as a toy for pranks, but it can also come in handy at some point.

For example, when Sirius was still a fugitive, in order to prevent him from approaching the castle, Felix made three seekers with his hair hidden.

Perhaps Grindelwald's approach was the opposite. When the two spectators were far away and exceeded a certain distance, one of them would give an early warning. Felix quickly simulated it in his mind, feeling that he could do it completely.

Think deeper, early warnings are not necessarily sounds, they may be vibrations, or some kind of strong stimulation. Therefore, when Grindelwald is forced to leave Neville (in fact, it is also far from Hogwarts Castle) exceeds a certain distance, the mirror will automatically start to operate.

The above is just Felix's momentary conjecture. He is not sure how far Grindelwald's understanding of ancient magical texts has reached. Grindelwald has never shown his attainments in the field of ancient magical texts, but he has read ancient magical text magazines and occasionally takes the opportunity to talk to Felix about the above content, but none of them involve magical skills.

If Grindelwald had had this idea since then, then his mind would be quite terrible.

Of course, Grindelwald could also use another student's hair to make a lookout lens, which might be more concealed, but Dumbledore or Felix were not allowed to think of this and conduct targeted inspections.

With limited information, Grindelwald chose the most conservative solution, which he believes is the most secure.

As it turned out, he succeeded. Felix checked his office, and the items he carried with him might have magic attached to his skin, but ignored the possibility that he could swallow a spectator. The truth that Felix didn't know was: his coma spell was indeed powerful enough. It was still an unknown whether the spectator could awaken Grindelwald in a coma, at least it must be later than he expected to wake up, but the stinging spells of the International Wizards Federation Law Enforcement Team weakened the effectiveness of the coma spell...

With the combined effect of these reasons, Grindelwald almost woke up as soon as he got on the carriage. But he was still bound by the spells of the law enforcement team members and could not move all over. Except for the spectator in his stomach that would jump every once in a while, he felt it all when Dumbledore and Felix transferred the secret key of the talisman.

"Professor? Professor Happ?"

"Oh, I think of one thing, I can't confirm for the time being - is there any problem?" Felix asked in his senses.

"Well-I also want to ask: Why didn't Professor Dumbledore transfer the spell earlier or delay the troubles on me?" Harry asked, "this way Grindelwald might not run away."

"He didn't tell me directly, so he could only guess." Felix whispered: "I guess Dumbledore had already had a hard time using magic in the last period of his life, and the transfer of the talisman had a great impact on him - do you know that magic can flow between the body and soul of a wizard?"
To be continued...
