Felix was in a heavy mood. Although he had only met Nick Flamel once, he had communicated with him many times through magic photos. To him, Nick was closer to a teacher.

"Wait a minute, Headmaster Dumbledore, I'll bring something with me."

Paris, France.

Felix revisited the old place. Under the guidance of Dumbledore, he came to a secluded street. Two streets away, it was the place where the Muggle Conference of the Booth Reis Hotel was held during the summer vacation.

He saw a group of energetic young people here. Their young faces were still vivid in his mind, the student leader Uriah, Matt who was captured but did not utter a word, Byers who valued friendship and family affection, and the innocent Bethenny...

Dumbledore handed Felix a piece of paper with "7 Montmorency Street" written on it. When he read the address in his mind, a small white house suddenly appeared from the air in the middle of two lawns.

"Fidelius Charm." This thought flashed through Felix's mind.

He glanced at the magnificent clouds in the sky and followed Dumbledore into the house. Inside was a medieval-style living room, with all kinds of strange glass containers, candlesticks, and copper globes on the table. Several sofas were covered with white sheets, and the top of the fireplace in the corner was blackened by smoke.

On the other side of the spiral staircase in the corner was an exquisite bookshelf filled with books. On the table opposite the bookshelf was a large crystal ball, with light shining through the thick dust.

Under Dumbledore's guidance, he came to a bedroom on the second floor. On the brown door hung a small wooden sign that read: Nick and Perenelle.

When he opened the door, an old man lay quietly on the bed, his chest motionless, his face frighteningly pale. When he got closer, he heard a faint snoring.

"Nick," Dumbledore said softly, "Felix is ​​here."

After a long while, the old man opened his eyes. There was a layer of white film on his eyes. He said in a trembling voice: "Felix?"

"It's me, Nick. Long time no see." Felix said casually. The spyglass hidden in his pocket was held in his hand. This belated Christmas gift might not be given away.

"Felix, I have been looking forward to the day when I can really meet you," Nick tried to open his eyes, but his eyes were blurry. "But, something delayed me."

"Don't you have the Philosopher's Stone? How could it be..."

"It's destroyed, child. I have lived for nearly seven hundred years. Death... is not a bad thing."

Nick Flamel stretched out his hand from the quilt tremblingly. "Felix, ouch!" He cried out in pain.

Felix heard a crisp click. He was silent for a while. Although the timing was wrong, he still wanted to laugh. He remembered the scene when the two met for the first time, when Nick moved away in small steps. He shook his fingers lightly, causing the quilt to move down a little.

"Thank you."

Nick spread his palms, revealing a golden key.

"I know I'm going to die soon, but it doesn't matter. Perenelle and I don't have children. Before I die, I need to find someone to inherit my knowledge."

"Why me?" Felix asked. He focused on magic runes, not alchemy, and Nick Flamel would know it.

"I want this world to be better. You are the most suitable candidate. All aspects meet my requirements. This is the result of my careful consideration."

Felix's heart beat. What a huge amount of knowledge Nick Flamel has researched for hundreds of years. Moreover, the paths of the two can be said to be extremely compatible, and there is a natural connection.

"Have you thought it through?" He suppressed the joy in his heart and confirmed again. He subconsciously ignored the old man's opening words.

"Except, except for a little worry, I added a condition for this." Nick Flamel said, his cheek tilted to one side, facing the window, and he could vaguely hear the sound of cars passing by.

Felix's expression became cautious, and he knew it wouldn't be that simple. But he really didn't want to miss this rare opportunity. No matter how difficult the conditions proposed by Nick Flamel were, he would try his best to complete them. Besides, he didn't think that Nick would ask for something he couldn't do.

So he said gently: "What do you need me to do, Nick?"

The old man gasped hard, his chest was like a worn-out bellows. Dumbledore said softly: "Nick, you..." But the old man shook his head, "Don't stop me, Albus."

"Felix, remember what I said when we first met? Old people like to embed themselves into a position in the world to pursue a sense of security."

His eyes suddenly widened, his face was pale, and he looked a bit like a ghost.

Felix's heart sank. He knew what Nick was going to say! Sure enough, the old man panted for a while and said: "All this time, I have been getting to know you. The more I know, the more I worry that you will go astray. So hey, cough cough! As long as you sign a contract, everything I have will be yours."

"Unbreakable oath?" Felix hid his face in the shadows, and his words lost their warmth.

The Unbreakable Vow is a magic oath between wizards. It is very powerful. Those who break the oath will only die. Felix had signed magic contracts with others before, but compared with the Unbreakable Vow, the difference in the degree of restraint is simply a world of difference.

He could still find ways to get rid of and transfer the magic effect of the former, but he had no way to deal with the latter.

Nick panted and said nothing, completely acquiescing to Felix's guess. He just tried hard to raise the key in his hand, but he was a little powerless.

"It's hard for you to come up with such a solution after careful consideration." Felix said sarcastically.

"I, cough cough!" Nick coughed violently.

"I'm sorry."

"Don't rush to refuse! Felix, my conditions are not harsh, you can listen to them first."

"I'm not interested at all."

Felix looked at Dumbledore, his eyes full of inquiry: "So, you are here to be a witness?"

"No, Felix." Dumbledore said sadly: "I don't know what Nick thinks," he looked at the old man, and said in a deep voice: "Nick, we all know that this is not a good idea."

Nick did not refute, "I, I know, if I have time I will observe him for decades, but, Felix, I am dying."

"This is your business," Felix's light blue eyes stared at Nick Flamel, and he kept trying to raise the golden key in his hand, "I'll give you a suggestion, before you die, you can find another person who is willing to sign the contract."

Nick seemed to be more energetic, and his words became fluent: "If, if you agree, you will inherit all my property, not just the ones you see. I have twelve safe houses and seven libraries around the world, which contain my nearly seven hundred years of accumulation: alchemy, ancient magic runes, magic notes, ancient magic... I am also the director of Beauxbatons. As long as you agree, everything will be yours..."

"Believe me, the conditions are not harsh." His eyes were full of hope.

Felix said coldly: "I am not stupid. I have nothing to say except rejection."

Nick fell into silence, the light in his eyes faded, he suddenly struggled to sit up, leaning against the wall, this action made his body tremble constantly, "Albus, please please leave for a while," he said panting.

Dumbledore glanced at him and Felix, sighed and said: "Nick, you..." He turned and left.

There were only two people left in the bedroom.

Felix sat on the only chair, with his right leg raised and the black magic wand twirling in his hand. He said easily, "What do you want to do? Let me watch you die? You can't do anything now."

Nick smiled and said, "This happens to be my advantage. I'm going to die. This is my advantage." He emphasized this point deliberately.

Felix looked at him in surprise.

The old man said softly, "Your answer has not changed. You hate external constraints. So, I have a backup plan." He stretched out his hand, and magic symbols appeared in his palm one after another. These magic symbols condensed into a golden eye.

"Do you know ancient magic?"

"The advantage of living a long time is that you can learn by analogy. In fact, I have never practiced..."

Felix asked cautiously: "What do you want?"

"From you? No, no, I just want to visit your house..."

"You're dreaming!"

"I'm dying, Felix," the old man stretched out his hand and looked at him with pleading eyes, "No one will tell your secret!" "

..."

In the silence, Felix seemed to see the old man's life slipping away bit by bit, and every breath was accompanied by a snake-like hissing sound. He gritted his teeth and said: "Old thing, I will watch you die, and you can't avoid death!"

Nick Flamel laughed heartily, his tone was filled with satisfaction and relief: "You won't be disappointed."

Felix stood up, strode to the bed, carefully looked at the skinny and pale hand, and grabbed it when it was about to fall.
