"Help?" Regulus thought for a moment.

Cynthia pulled him over to an empty frame, "Phineas! ”

"What's wrong, Thea? Why do you think of me today? "It wasn't long before an old man appeared in the frame.

"Phineas, I want to see Professor Dumbledore." Cynthia looked at the old man in the frame and said with a serious face.

Phineas looked at his juniors and nodded. "I'll help you ask."

"Thea, will Professor Dumbledore help us?" After Phineas left, Regulus asked with some hesitation.

"Whether he wants to help us or not, we're always going to try." Cynthia looked at the Horcrux in her palm with a solemn expression.

"Albus has connected the fireplace here to the headmaster's room, you can go there." Phineas returned with good news.

"Thank you, Phineas." Cynthia looked at the old man gratefully.

She and Regulus walked over to the fireplace, grabbed a handful of Floo powder, and walked inside. "Headmaster Hogwarts!" Green flames rose and took the figures of the two men with them.

"Good evening, Cynthia and Regulus! What is the matter with you looking for me? As soon as the two stepped out of the fireplace, Dumbledore's voice rang out.

"Good evening, Professor Dumbledore! Sorry to bother you at this late hour. It's just that we really have something important to look for you. Cynthia looked excitedly at the wise old man in front of her.

"What the hell is going on?" Dumbledore pushed his frame up.

"Professor Dumbledore, don't you know if your previous promises count?"

"Of course!"

"Professor, I, I regret it! I need your help! Please help us! Cynthia said these words with a hint of tears.

"Professor, you must have recognized me the last time you asked me like that, I want to say that you are right, I am a member of the Dark Lord's command, and I drew the formation that time."

Dumbledore listened to the girl and nodded.

"I was very supportive of him, I joined voluntarily, and I admired and respected him. I helped the Dark Lord draw an augmentation array on his wand that was amplified by more than half, and I also drew a bloodkill array for him to resist the death curse. ”

"As I drew the Blood Killing Array for him, I felt the instability of his soul from him. Later, Regulus approached me and wanted to talk to me, and he said that the Dark Lord had inadvertently said that he could live forever. ”

"The two of us were very puzzled by this, even though he was powerful, no one could achieve eternal life! We think it's some kind of black magic at work. ”

"We eventually found a dark magic in ancient texts that fits these conditions - Horcruxes."

"Horcruxes?" Dumbledore stood up in surprise. "You mean, he made Horcruxes?!"

"Yes, Professor. And one thing happened that confirmed our suspicions. ”

"At Christmas, the Dark Lord summoned us to ask for a house-elf. So I brought Kreacher with me. ”

"After the Dark Lord took it, he let us go back, and that's the day we found a record of Horcruxes in the book."

"Later, Kreacher came back, and he told us that the Dark Lord had taken him to a cave and had him finish a potion and put a locket in it."

"Rael and I realized that the locket was one of his Horcruxes."

"One? Is there more than one? Dumbledore's eyebrows jumped.

"We think there's more than one, because the Dark Lord once gave Bellatrix and Lucius the same thing for them to keep. Those two things should be Horcruxes. ”

"Today, Regulus took advantage of my absence to drop the Horcrux in the cave." Cynthia said as she handed the locket to Dumbledore.

"But why did you choose to betray him? The stronger he is, the happier you are. Dumbledore scrutinized the locket in his hand.

"Because of my parents. Professor, he said my father and mother were...... Idiot. Moreover, after he split his soul, he became more and more insane, and ...... Horcruxes are the most evil form of dark magic...... Although we do not reject black magic, ......"

"I see, kid. I promised you that you can come to me at any time if you regret it. It's not too bad, I'll help you. Dumbledore looked at the two men with remorse in their eyes and patted them on the shoulder.

"Professor, there's ...... About the Death Eaters. Cynthia rolled up her left sleeve, revealing the hideous mark.

"Every Death Eater has this mark on his left arm, and he usually summons us through this, and in the same way, we can summon him with this."

"As for the other two Horcruxes...... Bella there, very difficult, can be said impossible. She is very obsessed with the Dark Lord. And Lucius there, I'm sure! ”

"I can be your undercover agent, and I will tell you the truth about the actions I know in the future, just ......"

"Just what?"

"Only, I hope you can save my mother."

"Cynthia, Mrs. Black, there's nothing I can do at the moment, and that would expose you. I can promise you that when Voldemort is defeated, I will help you. ”

"Thank you, Professor!" Cynthia looked gratefully at the smiling old man in front of her.

"If I could, I'd like to see that ancient book." Dumbledore made a small request.

"I can bring it to you now, Professor!" Cynthia turned and stepped into the fireplace.

"Thank you, Professor, for your willingness to help us." Regulus sincerely thanked him.

"As your principal, I have an obligation to help you, my children. As long as it's still too late. Dumbledore winked mischievously.

After a while, Cynthia returned with the ancient book. "Professor, this is the book that details how to make Horcruxes and how to destroy them."

"Very good, it's not early, you go back and rest!" Dumbledore hurriedly took the heavy ancient book.

"Good night, Professor!" After saying goodnight, the siblings did not go back to Black's old house, but returned to the dormitory.

"Rael, don't show up in front of the Dark Lord in the future." Cynthia looked at her brother.

"Why?" Regulus looked puzzled.

"I'm sure he'll be able to detect the purification array on your body and discover the theft of the Horcruxes. I can't let you risk it, I'll tell him you're missing. ”

"Thea ......"

"You go back now, stay at home, and try not to go out." Cynthia interrupted him.

"I'll talk to Al over there, and I'll help you take good care of her, don't worry. You must stay at home until Professor Dumbledore defeats him! ”

In this way, Regulus was forcibly sent home by Cynthia, and Cynthia's spy life began.
