After listening to Blake talk about the process of their "Marauders" group drawing the "Living Point Map", Darren really couldn't imagine that the man in front of him had actually worked with a few other partners to use a magic wand on a piece of parchment in the middle of the night to slowly sketch the "Living Point Map", which is not like the Black in his mind, it is almost the same as Lupin, but this is probably the reason why they got together and became lifelong friends.

But now Darren still has a question, "What about the magic that shows the location of people on the 'Living Point Map'? ”

"Do you mean the footprints and streamers on it?" After such a long conversation, Blake finally relaxed completely, and said with a smile, I can't believe that when the smile appeared on his face, when Darren first saw Blake, the gloom that was still surrounding him was gone, and only ease and happiness remained.

Darren felt that he was finally back for real, a normal Sirius Black, not the prisoner who had been imprisoned in Azkaban for twelve years, bent on revenge.

"No, of course it can't be, or we won't be able to finish it in three weeks, even in three months," Blake turned to look at Harry, "Then thank you father, Harry." ”

"My father?" Harry wondered, and the other two people in the office had the same expressions on their faces.

"Yes, it's because of your father," Blake paused at the mention of Harry's father, those memories must have been important to him, "and then Potter of course they knew how special this parchment was, so they asked me again and again, and in the end I could only tell the truth. ”

"They were a little angry at this, thinking that I shouldn't have used the magic items of my predecessors to make my own things, but I told them that this parchment only had some very initial magic on it, and that it was in our hands that it was a real map, so it should be our work. ”

"We were both very young at the time, and we were all happy when the map was done, so we thought it would be nice too, but Potter thought there should be more secrets on the parchment, because according to the notes, the final product of the parchment was a sign of the students' movements. ”

So, he also brought something from his own house, a bottle of potion. ”

"Potion?" Professor McGonagall suddenly interjected, "Merlin, you're not talking about ......"

"I'm afraid so," Blake smiled helplessly, "I said we were both young at the time, and we didn't know a lot of things. ”

"I think so, you were too young. Professor McGonagall's face was filled with regret, making Darren very curious about what they were talking about by "potion".

"What Potter brought from home was a potion that was arguably one of the most miraculous potions in history," Blake explained, "because the potion itself was liquefied magic." ”

"Liquefied magic!" Now, not only Darren, but even Harry was shocked, it was unbelievable that magic could be liquefied.

"When a large amount of magic comes together, there will be changes, such as the light you see when you cast a spell, which is itself a manifestation of the magic, and if you compress it further, a new change will occur. ”

"When magic is compressed, it turns into liquid?" Hearing Blake's words, Darren suddenly remembered, it seems that when Dumbledore and Voldemort were PK at the Ministry of Magic later, they did leave something on the scene, is that the magic of liquidation?

"To be exact, after extreme compression, the mana will take on different changes, one of which is to become like a liquid, showing fluidity and high concentration, but only a very few top wizards can reach this level. ”

"However, if the magic is released, it will disappear soon if there is no spell. ”

"Yes, normally, pure magic cannot be preserved, and must be solidified through some kind of transformation, but these transformed magic often have changed their nature and can only play a specific role. ”

"Is that a potion?"

"And that potion is different, it is still active magic, and it can still have a new effect with the spell, just like a living wizard who casts magic on a spell, or a top wizard, Dumbledore's level. ”

Even Potter guessed that maybe the bottle could be drunk directly to give the wizard a quick boost to his mana. ”

"Isn't that just like the blue medicine?!" Darren couldn't help but cried out.

"Blue medicine? what's that?" Blake wondered.

"Oh, some kind of Muggle envisionary, like myths and legends. Darren explained.

"Very interesting idea, but Potter didn't drink it, but used it to soak the 'Living Point Map', and as expected, when he soaked the map in the potion, those footprints appeared on it, perhaps because the spell was too advanced to manifest itself with the support of extremely strong magic, and Phineas couldn't provide that much magic, so he thought the experiment had failed and discarded the parchment. ”

"It's a good thing we have your father, Harry, otherwise this map wouldn't have shown the activities of the people in the castle," Blake said warmly, "and then the professors wouldn't have been able to spot Peter, and your father saved me again." ”

Darren thought for a moment and whispered to Professor McGonagall, "Looking at you just now, is the potion that Harry's father brought very precious?"

"Precious?" Professor McGonagall pouted, "that would probably be the last bottle of this potion in the world." ”

"The last bottle?"

"Yes, that potion was invented by a wizard hundreds of years ago, and he found a formula that could stabilize the magic power, but before he could find an apprentice to teach him how to make it, he himself died in a battle with the dark wizard who came to snatch the potion formula, so he didn't even have time to take a name, and because this potion was so magical, later wizards didn't feel qualified to name it, but as long as they used it, they knew that it meant 'that kind of potion'. ”

"After that wizard died, was there no more?"

"The people at the time didn't know exactly what happened, only that the battle was very fierce, the wizard's house was burned down, and all the information was destroyed, so people didn't know about this potion for a long time, and it wasn't until much later that the wizards were shocked by the miraculous effect of this potion, and there were only a few finished bottles, but no one knew if it was from him or ......" Professor McGonagall suddenly stopped and sighed. Anyway, legend has it that one of the recipes for the Philosopher's Stone is this potion, and it is also the most important one, so Nicol Lemay only made one Philosopher's Stone, because he didn't have this potion anymore......"
