HP: After binding to the strongest wizard development system

"Haha..." Till laughed dryly. She really forgot to tell Grindelwald about this.

Before she went to Nurmengard last time, she had planned to tell Grindelwald about this in person, but the library tower in Nurmengard was too tempting. Till lived and ate in the library tower, and her mind was filled with all the things she wanted to see. He couldn't finish the book, and of course he couldn't remember to tell Grindelwald the good news.

"Forget it, at least I'm not the last one to know." The night was getting darker, and Grindelwald was also a little tired. As he spoke, he covered his mouth and yawned, then waved to Till, "I was just passing by Hogg. Watts, come here to see you and leave now."

Tier's face was full of disbelief: "Really?"

Does Grindelwald seem like such a laid-back person?

"Of course it's true." Grindelwald said without blushing, "You should leave quickly."

Till looked at Grindelwald suspiciously, but she couldn't see Grindelwald's expression clearly in the dark. In addition, there was still a night training mission to be carried out. Till didn't tell Grindelwald more and quickly raised his hand. The wand is back on patrol.

But just as Teal suspected, Grindelwald certainly did not come to this castle that had begun to sleep just for the simple reason of "passing by".

Grindelwald walked for a long time as if wandering around the castle, but when he was about to reach the principal's office, he suddenly turned around and disappeared into the empty corridor.

Almost as soon as Grindelwald disappeared, the stone beast in the principal's office moved out of the way, and Professor Dumbledore, with a solemn expression, walked out vigilantly, holding up his wand.

"Who is it?" Professor Dumbledore said coldly. His cold voice echoed in the corridor. No one responded at all, but Professor Dumbledore still did not take it lightly.

He believed in his feeling that the rich black magic aura that had just flashed away must be real!

When he received no response, Professor Dumbledore's expression became even colder: "Come out now, immediately!"

"Tick-tock...tick-tock..." A slight dripping sound sounded. Professor Dumbledore immediately looked in the direction of the sound, and smelled a strong smell of blood coming over there, and there was another person who looked slightly older than him. The taller man hid in the darkness and looked at himself quietly.

Professor Dumbledore's feeling was correct, but when that person actually appeared, he was speechless. He held the wand tightly for a long time before asking three words: "Who are you?"

"Who am I, you say?" Grindelwald chuckled, his old voice still carrying the shadow of his youth, and his tone was still as arrogant and wild as before, but Professor Dumbledore subconsciously trembled his hands after hearing this.

He heard it, how could he not hear it?

"Grindelwald——" Professor Dumbledore almost lost his voice. However, decades later, Grindelwald, who once again heard this surname from Professor Dumbledore's mouth, shook his body and then walked out. .

As he got closer, the smell of blood that Professor Dumbledore smelled became stronger. Only then did he realize that Grindelwald had cut his palm at some point, and drop after drop of blood fell on the ground. Under the dim light, The bottom is actually dark black.

Professor Dumbledore couldn't help but take a few steps back. The impact of Grindelwald's scratched palm was too great, as if he was taken back to the barn decades ago.

"Why, you didn't expect me to show up?" Grindelwald smiled, but his palms were bleeding and his blue eyes were red, which was really scary.

At least it won't make people think that his smile is because of happiness.

Professor Dumbledore did not answer Grindelwald's words, but took a deep breath and pointed his wand at him: "You should not leave Nurmengard."

"I left when I wanted to, just like I stayed when I wanted to stay." Grindelwald tilted his head, not looking at Professor Dumbledore's wand pointed at him, but boldly stepped forward.

With every step he took, Professor Dumbledore took a step back. Only when there was no way back, did Professor Dumbledore speak again: "Were those dirty things that entered Hogwarts previously done by you?"

The dirty things in Professor Dumbledore's mouth were the dark forces that held back many professors when the werewolves invaded Hogwarts.

Professor Dumbledore was still thinking about who was responsible for such a dark and terrifying existence, but now that he saw Grindelwald, he had some understanding.

Voldemort has lost power, and even if he is dormant, he will not have the energy to send so many dark forces into Hogwarts, but if it is Grindelwald who seems to be doing well in front of him...

Professor Dumbledore didn't want to doubt Grindelwald, but Grindelwald's expression was too meaningful, especially the raised eyebrow when he heard his question, which made Professor Dumbledore feel pain in his heart.

Sure enough, it was really sent by Grindelwald!

"Do you know you almost caused a big trouble!" Professor Dumbledore became furious when he thought about the children who were bitten by a werewolf because they were held back that day.

If Till had not improved the new wolfsbane potion early and provided a batch to the school, those students would have been left with a lifelong physical and mental shadow!

Grindelwald listened to Professor Dumbledore's question and shrugged nonchalantly: "What a disaster? What does that have to do with me? It's not me."

Grindelwald considers himself to have always been a cold-blooded person, especially compared to Professor Dumbledore, who always talks about "love" and "righteousness" in front of him, his cold-bloodedness is even more obvious.

But Grindelwald didn't care either. If he had, he wouldn't have stayed in Nurmengard for so many years. Now that he has regained his composure, he is just interested in the predicted future.

A future that Thiel and himself created together, consistent with the vision he envisioned when he was young.

As for Dumbledore...

Grindelwald chuckled, distanced himself from Professor Dumbledore, and looked at his former lover who was no longer an enemy or an enemy. He finally said a few words: "I was passing by and thought about how I had always been. I’ve never seen this castle, so I came in to take a look.”

"See you next time, Albus." Grindelwald deliberately lowered his voice when he said Professor Dumbledore's Christian name. Seeing the old headmaster in front of him glare at him, he smiled with satisfaction. , turned around and disappeared in place.

Grindelwald was gone, but there were still traces of his blood on the ground. The sad and provocative look in his eyes made Professor Dumbledore clench his fists.

After a long time, a deep sigh seemed to come from the silent night, echoing and dissipating in the long corridor.

How many years has it been, how many years have we not seen each other face to face? He thought there would be a day when we see each other again, but he didn't expect it to be like this tonight.

Grindelwald was far calmer than him.
