HP: After binding to the strongest wizard development system

Till's partner suddenly appeared at Hogwarts, and the three Harrys exchanged a few glances, and they all saw each other's faint anticipation and excitement.

Hope that’s what they think!

Grindelwald naturally noticed the little guy there who had been paying attention to him, but he had no time to pay attention to them. He walked directly into the castle and went to the principal's office to find Professor Dumbledore.

After having an in-depth reconciliation with Dumbledore, he felt much more comfortable coming to Hogwarts. He used to avoid people, but now he faced the curious eyes of many students without changing his expression.

Grindelwald had always been hiding from Dumbledore. Now he no longer needed to hide from Dumbledore. He didn't care what the students thought of him.

Professor Dumbledore was not surprised at all by Grindelwald's arrival. A pot of black tea, which Grindelwald liked to drink, had already been prepared in the principal's office: "Sit down, Till hasn't come out yet."

"How have you been recently?" Grindelwald did not look at Professor Dumbledore, but simply chose the softest and most comfortable sofa to sit on.

Grindelwald knew about Till's pickiness. He had observed that Till liked to sit on this sofa every time he came over, and it was indeed the most comfortable to sit on.

"It's okay." Professor Dumbledore didn't look at him either. Professor Dumbledore was looking down at Moody's letter. The substitute professor expressed his impatience for substitute teaching life - "I will definitely not be like Gilderoy." ·Like Lockhart, it’s a big joke! It’s the first time in decades that Azkaban has such a criminal!”

Grindelwald felt that the atmosphere was a bit silent, so he casually said: "I have been living in Hogsmeade Village for the past few days. Till came out to inform me."

Professor Dumbledore nodded silently, rubbed his shoulders tiredly, sat down and began to write a reply to Moody.

Grindelwald was a little frustrated. Although Professor Dumbledore reconciled with him, the original broken blood alliance was like a sharp blade stabbing between them, completely piercing their relationship. In any case, they could never regain the closeness they had when they were young.

What he wants is not reconciliation. They are no longer whimsical young people, but such a peaceful but distant way of getting along is not what Grindelwald wants.

What he wanted...actually he couldn't tell himself.

Grindelwald stood up quickly and placed the tea he had not drank on the small table: "I'm leaving first, you have a good rest."

Professor Dumbledore nodded but still did not speak. It was not until Grindelwald's footsteps moved away a little bit and the sound of the beating of the stone beast under the stairs was heard that he sighed and sat upright, looking at the ajar door of the office with vacant eyes.

He did not have direct eye contact with Grindelwald, so Grindelwald did not notice anything strange about him.

Professor Dumbledore was very aware of his physical condition and could still pretend to be in front of his students, but those who knew him well could tell at a glance that he was on the verge of physical collapse.

He didn't want Grindelwald to see his embarrassment. Whether it was his pride or the shame he had hidden in his heart for many years, he hoped that he would be calm and composed in front of Grindelwald, instead of dying with a withered skeleton.

As for what Grindelwald was thinking, Professor Dumbledore could probably guess. But in his heart, there was a difficulty that he had not overcome for decades. He could not forget the image of his sister Ariana Dumbledore dying in front of him, and he had never forgotten it.

What completely pierced their relationship was the rupture of the blood alliance, which was their spiritual schism, but before that, Ariana's death meant that they would never act together.

He hated Grindelwald, but he hated himself even more. What happened to Ariana was mainly because of his negligence and incompetence. If he could have paid more attention to Ariana at that time, if he could have been calmer, soberer, and realized earlier that the most important thing was never the ambition to unify the world, but his own family.

Will...everything will be different?

His little sister——

"No need to forgive me, I have never forgiven myself." Professor Dumbledore lived very calmly these days, because he thought of his little sister, his beloved sister who was killed by him.

If there is her in the other world after death, then death is not a pain, but a relief.

However, Professor Dumbledore was going to be disappointed. Late that night, Till left the potion room with two large bottles of antidote potion.

Different from the black magic potion used on Mr. Elcott, the color of these two bottles of antidote was dark blue, and they were obviously one pot, but they were brewed into two large bottles.

Till even doubted whether he made a mistake in brewing it, but after systematic testing, the properties of the two bottles of antidote were perfect, and Till's brewing process was also perfect.

It is worth mentioning that Thiel's character panel has been crowned with the title of "The Strongest Potion Master". The moment the two bottles of potion were put into the potion bottle, the progress value jumped from 99% to 100%.

This was the first and most powerful title that Till had received. Till was so happy that he didn't even have time to have a good night's rest and went straight to knock on Professor Dumbledore's office door with the potion.

Her patronus didn't stop either, and Snape and Professor McGonagall were quickly called to the principal's office by her patronus.

When Grindelwald received the news and rushed over, Tyr was already leaning against Snape drowsily.

Even in the potion room with a flow rate of five times the time, Till did not dare to rest more. He only maintained the minimum rest time, worked hard to squeeze out his potential, and brewed the antidote potion in the shortest time.

It does not mean that Professor Dumbledore can recover as before after drinking the antidote. The functions in his body have been eroded by the curse, and the haggardness and sickness on his face are truly affecting his body.

Till was quick enough, but she still felt sour when she saw Professor Dumbledore. How could she not see that Professor Dumbledore's current situation was very pessimistic and he was barely surviving. If Tier stays up for a few more days, Professor Dumbledore's situation will be revealed to the students.

Seeing Professor Dumbledore staring at the potion in a daze, Professor McGonagall couldn't help but urge: "Drink the potion quickly, we can't delay it any longer."

"Drink both bottles, it's safer." Although the system has determined the nature of the medicine, Till still feels that it is more reassuring to take both bottles of the potion together.

Generally speaking, a crucible contains the same amount of potion as a large potion bottle, but this time it was filled with two potion bottles - it was useless for her to keep the antidote potion anyway, Professor Dumbledore drank all of it. So that her efforts over the past few months would not be in vain.

Professor Dumbledore nodded solemnly, picked up the potion bottle and drank it. There was no taste in his mouth, he just felt like he drank a lot of water. However, after he drank both bottles of antidote, his stomach began to heat up. The heat spread from his stomach, not just to his right hand, but to his whole body.

The long-lost feeling of strength gradually revived in his body.
