The Chinese girl from Hufflepuff is both timid and brave

Sun Zhu hadn't seen Sirius since that unpleasant meeting in Hogsmeade. Although he did plan to visit him during this holiday, he was really caught off guard when he suddenly saw him here.

"Sirius!" Hermione waved, "Why are you here?"

"Harry went to Ron's house, and Mrs. Weasley is taking care of them. I was wondering if you wanted to go over and play with us?" Sirius looked at Sun Zhu, "I just happened to know that you and Zhu were together, and I have something to do with her, so I'm waiting here."

"How did you know Hermione and I would be here today?" Sun Zhu said in a sullen tone.

"Why don't we just ask the kid from Diggory's family?" Sirius waved his hand. "How about it, do you want to go?"

Sun Zhu glanced at the safe-like box in his hand, then looked at the busy Diagon Alley, and was speechless.

Such an important thing, but he was just carrying it in his hands? And he had to run around with two students?

Hermione hesitated for a moment, but shook her head: "Actually, my mother brought me to Diagon Alley. She must be waiting for me at Flourish and Blotts. Please say hello to them for me. See you after the holiday."

Sirius nodded, "Okay then, I'll take you to reunite with your mother."

Sun Zhu held Hermione in his arms as they walked, glaring at his box. He just laughed shamelessly.

When she saw Mrs. Granger, she was sitting in the corner of the bookstore, curiously looking at the book in her hand. After greeting her, she was surprised to recognize Sun Zhu: "I remember you, little girl. That time at the ski resort, you and your father... Yes, we met, and then..."

"Mom." Hermione hugged her arms, "We do have a good relationship with Senior Sister Sun. We met before entering school. She has always taken good care of me in school."

Unlike Hermione, as Muggle adults, the Grangers' memories of magic had naturally been erased. Apart from remembering Sun Zhu's face, they actually didn't remember that she and her father had saved them.

But the loss of memory did not diminish her enthusiasm, and after Hermione and Sirius explained, Mrs. Granger gave up the idea of ​​inviting them to her home and left Diagon Alley with Hermione.

This is probably one of the few places in the wizarding world that Muggles are allowed to enter, but only Muggle insiders who have wizards in their families are allowed to enter.

"Where are we going next? Grimmauld Place?" Sun Zhu put his hands in his coat pockets.

She and Hermione agreed to meet at noon, and it didn't take too long to get to St. Mungo's. The sky was only slightly darker at this time, and the sun had not completely set.

"Of course, it's safe and secluded enough there." He nodded, "Do you need me to tell your father how you were going to get back?"

Sun Zhu waved his hand: "Using what I gave you, it will only take a moment to destroy the soul fragment. I will still have time to go home after that."

"I heard that you were learning the Patronus Charm. How's your progress? If you have learned it, I will teach you how to use it to send a letter to your father." Sirius spoke on purpose.

Sun Zhu sat on the back seat of his motorcycle and said expressionlessly: "If everything goes well today, my progress in the Patronus Spell will be able to make a breakthrough. Do you understand what I mean?"

After all, the Horcruxes were gone, how could she not be happy? The Patronus had to show up for her.

But judging by its size, it's unlikely to be a bird of prey like a golden eagle. It's impossible that her patronus is an owl, right?

Sirius laughed. "Generally speaking, if you say that, there's a good chance something will go wrong. Don't you think so?"

"Pfft, pfft, crow's mouth! Your patronus isn't a crow, is it?"

"Of course not. Don't you know, many people's patron saints are the same as Animagus. I am no exception."

"Ahaha, no harm meant, but if that's the case, you really are a dog among dogs."

“That’s a nice compliment to me.”

When he followed him to the basement of the Black mansion, Kreacher was guarding the door. He looked at Sun Zhu with resentful eyes and kept saying, "There is no way... Old Kreacher tried, Master Regulus asked the useless Kreacher to destroy it, but Kreacher couldn't do it! Oh, Master! Old Kreacher really deserves to die..."

"Okay, just go and watch at the door." Sirius waved his hand, "When you have time, go and clean up the east room on the third floor. Moony will be back soon, and I'll let him live here."

Kreacher left cursing, and Sun Zhu sighed, staring at Sirius's seemingly careless movements.

She took the golden cup and locket out of the box before him, then patted him: "Didn't you tell me that the locket can affect people's mood and amplify the negative? Don't think about anything else. Destroying the things in this locket is also a way to avenge your brother."

Her necklace could protect her from the locket's influence, so she simply held out her hand to him: "If you can't do it, then I'll do it. But I think you are definitely planning to avenge him yourself, right?"

Sirius glanced at her and asked, "How much do you know about Leir?"

"...I don't know anything." Sun Zhu closed his mouth and squatted aside.

Instead, he smiled, sweeping away his gloom: "You know everything."

“…Get down to business!”

He slowly took out something like an injection from the box, and Sun Zhu recognized that the liquid inside was the basilisk venom she had given him before.

"You had your people do a lot of research on it? Was there any effect?"

"The specific results will depend on today's experiment." He looked very calm. "Dumbledore found me a professor who is very knowledgeable about potions and souls. He is the former head of Slytherin and has taught me and..."

"Professor Slughorn?" Sun Zhu blurted out.

Sirius had a look on his face that said "you know all this" and continued, "He said he made a mistake in this matter, although I don't think he should blame himself too much. Then he studied these, wanting to know what potion to combine with the basilisk venom to have the greatest effect. These two are his final results."

He tapped the two tubes of liquid that looked identical to Sun Zhu. "While dissolving the soul, it can resist the attack of black magic without causing any damage to the host soul."

Sun Zhu nodded, knowing that they actually wanted to rely on the effects of the golden cup and the locket to test how to safely remove the piece on Harry's body.

This is the real reason why they have not taken any action on the Horcruxes they have obtained.

"Unfortunately, these two are not living things. They are dead things without souls." Sun Zhu said: "The experimental results may not meet expectations, and the reference value is limited."

Sirius raised an eyebrow, "How will you know if you don't try?"
