Harry Potter, Ron, Hermione, and Asinsha arrive at their ancestral home at 12 Grimmauld Place, London, England.

This was originally Sirius Black's home, or the Blake family's ancestral home.

The Black family has a tapestry hanging in a room in this ancestral home, on which the family tree of the Black family is drawn.

This genealogy shows the family situation from the Middle Ages to the present day.

By the end of the 20th century, the Black family's paternal line had all died out due to the deaths of Sirius and Regulus Black, leaving no descendants.

But what is even more ironic is that the women of the Black family are still alive, with Narcissa Black marrying into the Malfoy family, and Andomeda marrying the Muggle-born wizard Ted Tonks, which was absolutely not allowed in the Black, where pure-blood values were previously entrenched, so she was removed from the family tree.

It is worth mentioning that the relationship between the Potters and the Black family is not entirely clear.

But Sirius, who has died, is only Harry's godfather, and there is no direct connection between the blood relationship, but the relationship between the two people is indeed family in the true sense.

Harry had been to this ancestral mansion before, and it was actually this time of the last year, according to Sherlock's explanation. B is Sirius's younger brother Regulus, and Harry returns this time and looks back at the Black family's family tree, but naturally remembers a conversation with Sirius, and the other party did mention that he has such a brother.

At that time, at this time last year, in this room, Sirius held out a finger and pointed to the name at the bottom of the family tree: Regulus Black.

The date of birth is followed by a date of death, which is marked about fifteen years ago.

"He's younger than me." Sirius at the time said, "I'm constantly reminded that his son is much better than me." ”

"But he's dead." Harry said.

"yes." Sirius said, "Stupid idiot, he joined the ranks of the Death Eaters. ”

"You're kidding!"

"Listen to me, Harry, don't you understand what kind of wizards my family is when you look at this house?" Sirius said impatiently.

"Your ...... Were your parents Death Eaters too?"

"No, it's not, but believe me, they think Voldemort's claims are correct, they are all in favor of maintaining the purity of the wizarding bloodline, getting rid of Muggle-born people, and letting pure-bloods take power, they are not unique, before Voldemort showed his true face, many people thought that his claims about some things were correct, however, when they found out that he would do anything to gain power, they were all timid and retreated, but I think my parents must have thought that Regulus was on board in the first place, Count as a brave little hero. ”

"Was he killed by the Aurors?" Harry asked uncertainly.

"Oh, no." Sirius said, "No, he was killed by Voldemort, or, more likely, at Voldemort's behest, I suspect that Regulus is not that important, and it is up to Voldemort to get rid of him personally, and from what I know after his death, he is already in a deep position, and then he is terrified of what others want him to do, and he wants to quit, alas, you can't hand Voldemort a resignation report and finish it, either die for life." ”

Harry recalls a conversation with Sirius, hoping to find a little bit of Sirius's prominent description of his brother from memory, such as whether Regulus likes to go somewhere, or some hidden place where he likes to hide things, maybe the Horcrux will be there.

But unfortunately, Sirius seemed to be very reluctant to talk too much about Regulus to Harry at the time, and it seemed that Sirius didn't know much about his brother, just like Sirius didn't know that Regulus had done great things until he died.

"Harry! Look who we found! Ron and Hermione ran up in a hurry, and Asin was careful even when going up the stairs, after all, this ancestral house was also very historic, and when the Black family died, it would become an antique building.

As the oldest and largest pure-blood family in the wizarding world, the Mephisto people are very sad every time a pure-blood family in the wizarding world dies.

"You must tap your voice here!" Harry blamed Ron for not liking the trouble people making in the Black family's ancestral home, which seemed disrespectful to the dead.

But when Harry saw Ron holding the house-elf Kreacher in his hand, Harry was overjoyed, maybe Harry didn't know where Regulus would put the Horcrux, but Kreacher, who had served the Black family all his life, must know some clues.

At first, Harry's kind words persuaded him, and then he directly threatened Kreacher to tell the truth, and the house-elf never said a word, but when Harry said the name Regulus, Kreacher began to cry.

"Listen to Kreacher, if you want to disobey the Mephisto people, don't forget that you're just a house-elf who has lost your people!" Asinsha walked up the stairs and said just one thing to Kreacher.

And Kreacher didn't dare to behave too presumptuously in front of Asinsha, "Kreacher don't dare, honorable Miss Mephisto, the little master of Regulus has warned me not to say it to the public......"

Kreacher cried frustrated and cried bitterly, and then blamed himself for not completing the final task that Regulus had assigned.

And Harry and the others also learned about the past from Kreacher's mouth.

During the time when Regulus became a Death Eater.

Voldemort had asked him for a house-elf to experiment with, and he recommended Kreacher, but told Kreacher to do what Voldemort told him to do and go home.

Regulus found a clue in Kreacher, who was frightened when he returned home, and became suspicious of Voldemort.

In order to protect the Black family, he took Kreacher to the cave where Voldemort kept the Horcruxes some time later, drank the poison, and exchanged them for the Horcruxes...... Slytherin's locket.

He gave the Horcruxes to Kreacher and ordered them to destroy them without telling anyone else about it, and he was dragged into the water by the corpse to drink water, and his mother was "maddened with grief" for it.

He left only a suicide note from a replica of the Slytherin locket, .B.

In fact, even Voldemort was negligent, and he set a very strong ban in the cave where the Slytherin locket was hidden, which made it difficult for some wizards to escape directly from the cave, at least the apparition would never work.

However, Voldemort neglected the unique magic of the house-elves, and the peculiarities of their species' magic, and the loophole in Voldemort's prohibition allowed Kreacher to escape from the cave.

That's what happened next.

Regulus hoped that Kreacher would be able to destroy Voldemort's Horcruxes.

Regulus, unlike the other Death Eaters and Dark Lords, saw house-elf and Muggle life as mustard. When he realizes that the Dark Lord is trying to kill Kreacher, he turns around and realizes Voldemort's cruelty.

He arrives in the Black Lagoon caverns to destroy the Horcruxes, preferring to drink the poison himself rather than the elves.

He was one of the first to discover Horcruxes.

The Slytherin locket was one of the first Horcruxes to be discovered.

But how could the Dark Lord's Horcruxes be destroyed by a house-elf, no matter how Kreacher tried all the tricks he could think of, without success.

This caused Kreacher to be disheartened by the inability to complete Regulus's will, and had to hide the locket in the house.

When Harry heard Kreacher say that the Horcruxes were hidden in this house, Harry's heart was pounding again, and it was undoubtedly exciting to finally be able to find a Voldemort Horcrux in such a short period of time.

"Bring it to me!" Harry ordered that after Sirius' death, he could inherit Kreacher directly from his godfather.

"But it's not here anymore."

"What do you mean?"

"Montongues. Fletch stole it, and in fact the burglar stole a lot of things from the house! Klee counted some of the things that Montungus had stolen, including a first-class Merlin badge.

"Isn't that ......what he said about Mondongues," Ron couldn't help but interject, in fact, they had been in contact with Montungus two days ago, and Harry should also thank the other party for being willing to come over and help him move from the privet road at that dangerous time.

But after listening to Kreacher's words, Harry felt a tired anger at Mondongues, how cheap a person must be to steal something from someone else's ancestral home.

"So that box is also in Mundungus's hands, are you sure?" Harry asked Kreacher one last time.

Kreacher nodded affirmatively.

"I'll have to get in touch with Moody, Moody will definitely know where Mondongus is, they're all connected, when Dumbledore was still alive, Mondongus gave information to the Order of the Phoenix, all about the Death Eaters and Voldemort." Harry said.

Ron said, "It sounds like this Mundungus is also quite powerful, and it is not unusual to be able to find out the information of the Death Eaters and Voldemort. ”

Asin Sha didn't have a good impression of the name Montungus: "A mercenary villain, of course, he can also be seen as a businessman who dares to do anything, as long as he gives enough benefits." ”

"Kreacher, I tell you to do something, find Moody, and tell him to go find Mondongues, we are still waiting for him at Black's ancestral home, and if there is any doubt about something, you can come and have an interview." Harry said to Kreacher, and the older house-elf disappeared into thin air.

At this time, the Order of the Phoenix had not lost its troops, although the soul figure had passed away.

Harry and the others stayed in Black's ancestral house for another day, and waited until the early hours of the next morning, when Kreacher and Moody didn't show up.

Harry could only pray secretly that Moody would not have any other accidents outside.

Hermione, on the other hand, managed to get her hands on the Daily Prophet newspaper from the outside.

"You went out and bought a newspaper." Ron and Harry couldn't believe it.

Hermione dressed herself as an old lady, and there was a vending office for the Daily Prophet just around the corner from the street.

However, as the ancestral home of Black, this place is likely to be targeted by the Death Eaters.

Hermione would be scary to go out like this.

"Look at this news, it's definitely sensational."

Hermione was unhappy with Ron and Harry's accusations and threw the newspaper in their faces.

Hermione returned to her and Asinsha's room, then climbed into bed and slept in Asinsha's bed, which had not yet woken up.

"Sherlock Mephisto has been appointed Professor of Defence Against the Dark Arts at Hogwarts! Hogwarts School of Witchcraft and Wizardry is back in the safest place in the wizarding world. ”

Ron read out the eye-catching headline of the news.

When the wizards in the wizarding world learned that Sherlock had become the Defence Against the Dark Arts professor at Hogwarts, they couldn't wait to say that all the children who stayed at home were sent to Hogwarts.

After all, there is no place in the wizarding world that is safer than Hogwarts.

Even after reading the newspaper, Ron even planned to go back to Hogwarts to go back to class, after all, he should still be in seventh year, even if it was reasonable to go back to school now.

Harry patted Ron on the shoulder, "At least Ginny will be safe inside the school, the Death Eaters will never dare to break in, and Mr. Sherlock will be much tougher on the Death Eaters." ”

Ron said in a strange tone, "I'm not worried about anyone else, I'm thinking about whether or not I'm going back to Hogwarts tomorrow." ”

Harry "......"

A loud bang interrupted Harry and Ron's communication.

By the time the two of them descended the stairs, they saw Moody and Lupin in Montungus in uniform appearing directly in the hall.

"I was just wondering when you guys would come, but I didn't expect you to come too, Lupin." Harry said ecstatically.

"When Kreacher found me, I was staying with Lupin at Tonks' parents' house." Moody's said.

Lupin had other news to tell Harry, "I have a baby with Tonks, and it will be born soon, around Christmas." ”

Harry didn't have time to bless him, and Mundungus was there yelling, and Kreacher came out from behind and slammed the pan on the knee.

"What am I doing wrong? You're all going to treat me like this, and I've even helped you Harry...... You're so ungrateful......"

Mundungus exclaimed.

Harry's face flushed, and it was true that Mundungus had helped Harry get out of the privet road.

In the original books, it was the cowardly Mundungus who killed Moody, but now that Sherlock intervened, Harry did not have such a deep opinion of Mundungus.
