Chinese students at Hogwarts.

Sirius spread his hands, pulled up a relatively sturdy wooden chair, and looked at the Black family crest engraved on it with disgust.

He sat down on it:

"Okay, okay, I'll just wait here, clean up the hall, and figure out how to get my mother's portrait off the wall."

Kreacher did not dare to directly insult Black, so he walked out of the room sobbing softly, cursing Sirius in a low voice using words he had never heard before.

The four little ones have jumped to the top floor, and they are ready to start cleaning up from here.

The Black family's old mansion was so big that it seemed to have cast a traceless stretching spell, making the five-story building look like a maze castle.

It didn't take long for the four little ones to run down, and Ron said with a very experienced look:

"All the velvet curtains have a lot of foxworms hiding in them and we need a lot of foxworm killer."

This does not take into account that the effect of magic on living creatures is much worse than that on dead creatures.

Malfoy crossed his arms and praised uncharacteristically: "Weasley, it seems that you are quite talented at doing housework. Unlike me, I can't do anything."

"Really? No, it's just that I often see my mother doing housework, so I'm influenced by it." Ron said rather embarrassedly.

Harry and Hermione next to them were already covering their faces and couldn't bear to look at them. They were not complimenting you, Ron!

After arguing for a while, Zhang Xiao finally found out through Black's suggestion that there was actually a store specifically for elves to buy things. They didn't need to bring money, but they kept accounts.

Whatever the master needs, the elf will buy it. The account will be recorded in the master's family and settled every month.

The next time they had to write a long list and gave it to the elves.

Fortunately, the elves are very fast. In almost a blink of an eye, they come back with large and small bags of things.

Each of the little wizards held a large bottle of Humeizi pesticide filled with black liquid.

Malfoy also packed a considerable amount of Mrs. Skoll's All-Purpose Miracle Stain Remover into his small satchel.

The crowd dispersed again, and Zhang Xiao took Kreacher to the foyer on the second floor. He still remembered that in the original book, Slytherin's locket seemed to be found here.

It's just that in the original book, this old house has been initially cleaned by members of the Order of the Phoenix, but at this moment, it looks like it has been deserted for decades. There is thick dust everywhere, and the originally beautifully patterned carpet has turned black. It's rotten stuff that can't be seen clearly.

It's hard to imagine how Kreacher survived here, or what he had been doing in the ten years since Mrs. Black's death.

"Light!"

Zhang Xiao snapped his fingers again, pinched his waist and looked at the extremely dirty living room that was illuminated. He murmured softly:

"I love magic!"

He pulled out his wand and waved it wildly:

"The whirlwind sweeps away! The whirlwind sweeps away! The whirlwind sweeps away! The whirlwind sweeps away!"

The strong wind seemed to have a special attraction and stirred up large clouds of smoke and dust around it. Soon, a huge gray wind ball condensed in the center of the room, and the thick dust almost formed a solid body inside.

Zhang Xiao thrust out the magic wand forward, as if thrusting out a sharp sword:

"Clean up!"

I saw cracks of light shining on the dust-gathered smoke ball. The smoke ball twisted and shrank rapidly, and finally disappeared.

Zhang Xiao put down his wand and took a slight breath.

Only Kreacher stood behind him and glanced at Zhang Xiao in awe, muttering in a low voice: "The powerful and noble young master."

This set of actions may seem simple, but it is actually supported by powerful strength. The lower limit and upper limit of the "Cleaning Up" spell are very high.

Hermione was able to use this spell in her first year, and in her second year she was even able to use Restoration.

But the most she could do with her cleaning was to remove the words on the parchment and some minor stains.

Even some housewives who are relatively proficient in household magic can never let Zhang Xiao clear this big ball of smoke and dust like this.

After cleaning up the dust, the entire large living room looked much more pleasing to the eye. The paint on the furniture had long since peeled off, revealing the underlying color of the wood, although it looked dilapidated.

But we can still see the glory and wealth of the Black family.

Zhang Xiao tried to restore the things here to their original state, but the effect can only be said to be limited. The effect of the repair spell is quite powerful, but the longer it is used, the worse the effect.

It's like using it on a cultural relic and it's hard to turn it into a freshly baked product.

After trying several times and being able to barely repair it, Zhang Xiao simply gave up on this thankless job.

There’s no shortage of money, so why bother.

He walked over to the glass-fronted cabinets on either side of the mantelpiece.

It was crammed with all sorts of oddities: a collection of rusty daggers, animal paws, a coiled snakeskin, and a host of dull, black silver boxes.

It was engraved with characters that Zhang Xiao couldn't understand, which looked like goblin script or runes.

The most uncomfortable thing was a decorative crystal bottle with a large opal embedded in the stopper. The bottle was filled with something that looked like blood.

Zhang Xiao waved his magic wand, and the cabinet opened automatically. The contents flew up and landed in front of the big box that had been prepared.

Kreacher suddenly asked in his low and hoarse voice:

"Dear young master, what do you plan to do with the Black family's property?"

Zhang Xiao answered easily while waving his magic wand to guide these things to fly into the cardboard box:

"Kreacher, don't worry, Sirius only lent me the right to use it temporarily, but this house still belongs to the Black family.

I plan to find a room large enough to store these things upstairs without throwing them away or selling them.

If you are worried, I can leave the maintenance of these things to you, you only need to be responsible for taking care of them. "

Kreacher widened his gray eyes, looked at Zhang Xiao in disbelief, and asked eagerly:

"Dear little master, are you telling the truth?

Won't these things be cleared? Could I be responsible for guarding the Black family property? "

Zhang Xiao nodded, used the floating technique to lift up the almost full large box, and walked downstairs.

"Kreacher, if we were together longer, you would know that I never joke."

Kreacher bent down deeply, his big nose almost touching the floor, and almost cried with joy:

"Thank you, kind, great, noble young master!"

"Malfoy, Hermione, come here, see what we found!"

In one room, Harry shouted loudly and quickly covered half of his face with a tea towel. The little witch covered in gray and the equally gray-faced Brother Drag ran over from another room.

"Potter, do you know that you have to concentrate when you work, otherwise we won't be able to finish it in a few days if we follow this method!"
