Godson and godfather!

Felix stood quietly aside, his brain working at high speed.

Dumbledore's words were clearly directed at Harry Potter and Sirius Black.

He never expected that there was such a relationship between the two.

And Sirius was accused of being Voldemort's minion and betraying his best friend, Harry's father.

Felix thought of an organization active in the war years - the Order of the Phoenix. This was a secret organization founded by Dumbledore to resist Voldemort, and assisted the Ministry of Magic in fighting Voldemort and the Death Eaters during the war.

The Order of the Phoenix was not well-known, and it was disbanded after Voldemort disappeared and the war was won in 1981.

Felix knew this name because he knew Professor Tofty of the Wizard Examination Bureau - he was also an expert in ancient runes, and Felix had visited him.

Professor Tofty mentioned this organization in a casual chat and praised the bravery of the members of the Order of the Phoenix, but he did not say the specific name.

But Felix speculated that at least Harry's parents, Sirius, and Peter should all be members of the Order of the Phoenix.

No wonder... no wonder Dumbledore was so angry.

They were best friends at school, close comrades after graduation, and the family bond formed because of Harry's birth. This should have been an unbreakable friendship.

But Sirius Black chose to betray.

What role did Snape play? According to the information Felix found when he was in school, after the war, Snape was accused of being a Death Eater, but Dumbledore bailed him out as an undercover agent and did not let him stand trial at the Wizengamot.

Otherwise, Hogwarts would not have such a sharp-tongued professor.

'So, Severus should also be a member of the Order of the Phoenix.'

Felix didn't know much about his dean's experience at school, but he at least knew that the relationship between Snape and the Potters was complicated: he was an old acquaintance of Harry's mother - perhaps even had some admiration, but was a mortal enemy of Harry's father.

Wouldn't they fight when they had a meeting together?

...

"Felix," Dumbledore turned his head, his blue eyes fell on him through the lenses: "You are a professor of the school, I don't want to see you make the wrong choice."

Felix blinked, "Principal, you don't need to tell me that I will also put the safety of students first. Besides, Mr. Potter and I have a good relationship. I don't want to see him get into any accidents. I even trained him during the summer vacation." "

Ah, I heard about this from Filius," Dumbledore said, "He said that you have done a lot of research on the magical riots of little wizards..."

"It can't be considered research, I just experienced it."

Dumbledore's expression became gentler, not as sharp and aggressive as at the beginning.

He said in a tone of discussing magic: "Can you tell me about it, Felix? Please forgive the curiosity of an old man."

"It all started two weeks ago... I ran into Potter by chance in Diagon Alley and found that he had active magic. I judged that he had recently experienced a magic riot. After asking, it turned out to be true."

"Your sensitivity to magic is amazing, Felix."

"Thank you, Dumbledore. After that, I..."

"I think so..."

The tense atmosphere in the office gradually eased.

Dumbledore turned into a gentle old man again, discussing the impact of the magic riot with Felix with great interest, and gave his own opinions without hesitation.

"Principal Dumbledore, I am thinking about a question. Can we artificially intervene in the activity of our own magic? The benefits of this are obvious."

"This idea is very interesting, but you must be cautious, Felix. Any research on magic itself can easily cause serious magic accidents."

When Felix walked out of the principal's office, he held two books in his hands.

This was handed over by Nick Lemay to Dumbledore. This is also one of the disadvantages of communicating between the two through photos. Nick Lemay lives in a safe house all year round and rarely goes out. Owls can't find him at all.

And with the current friendship between Felix and him, it is obviously not as good as the past visits.

He was not surprised at this. Feelings are accumulated little by little. He is not a gold galleon. He will not win the trust and love of everyone at once.

He stuffed the two books into the ring and returned to his office. When he sat on the sofa, he was still thinking about what the portrait of Headmaster Phineas Black said.

No. 12 Grimmauld Place, this is the location of the Black family's old house.

Although there is only such a name and no additional information, it is enough for Felix.

This is obviously the way ordinary people name places, and he can start from this aspect.

After circling a rough range, the rest is to explore a little bit. As long as he is given time, he can dig out this secret residence.

This is not difficult. The portrait of Phineas Black said that he can do it, and Felix thought so too.

The difficulty is how to break the magic above.

For these pure-blood families, the old house must have imposed various complex and even incredible protective measures. The whole process can often last for dozens or hundreds of years and take the joint efforts of several generations to complete.

Moreover, if the old house is imposed with the Fidelius Charm, then he really has no way to deal with it.

However, according to Phineas Black, he also has a portrait in the Black old house, which shows that he knows the old house well enough. In order to let Felix rescue the last blood of the Black family, he will not let Felix do useless work.

Besides, this is not a safe house, and it is too troublesome to use the Fidelius Charm.

Another key clue provided by Principal Phineas Black is that it is necessary to use "something unique to the noble Black family". What would it be?

He already has some guesses.

Thinking hut.

Felix sat on the sofa and stretched out his hand to call over a thick book. It was the "Pure Blood List" written by Cantankerus Nott, which recorded the relevant information of the so-called "Sacred Twenty-Eight Families".

He turned to the part of the Black family and quickly skipped a series of lists of family members and their deeds.

His eyes fell on the coat of arms of the Black family, which was a French phrase - 'Forever Pure'.

He laughed.

For the noble and ever pure Black family, what could be called unique?

Only blood.

As long as he got Sirius Black's blood, he could enter the old house of the Black family and take a peek at the collection of books inside...

Felix came out of the thinking hut, looking at the night of Hogwarts, his eyes blending into the darkness.

Sirius, where are you?
