After everyone's persuasion, Sirius finally agreed to change his wand.

He sighed and walked into the wand shop after Mr. Ollivander, rubbing his messy hair feebly, like a young wizard just coming of age.

"He used to be like this, he seemed very stubborn, but as long as it was a reasonable suggestion, he would take it at most"

Looking at Sirius's back, Lupin told Aven, Harry, and Hermione some things about Sirius's school days, which made everyone laugh.

Amid laughter, they arrive at 36 Diagon Lane, a shop belonging to the Black family.

It was a three-storey street-facing shop, located at the other end of the street, across the street from the Ollivanders Wand, next to a potions shop, and across a dark alley to the north of it was the Babbling Owl Shop.

Harry's pet, Hedwig, was given to him by Hagrid after he bought it there.

In addition to the pet shop, even this potion shop is very famous in Diagon Alley, because of the cheap price, Evan mail-ordered a lot of potion materials at their house.

The exterior walls of the potion are brown and black bricks, with only a small window. Inside, there were rows of barrels of goo on the floor, and near the wall, all sorts of jars of powder, herbs, bundles of feathers, fangs, and claws hung from the ceiling.

The merchandise inside looks fascinating, but because of the potion material, the store has an unpleasant smell from the outside, like a mixture of rotten eggs and rotten vegetables.

Even worse than that is 36 Diagon Alley next to it.

The old bricks are in ruins, and they look extremely desolate and dilapidated. The two semi-circular windows were covered with a thick layer of dust, and the inside could not be seen from the outside. Between the windows was a scarred black wooden door, covered in insect eyes and marks of sharp objects, releasing the smell of decay.

Evan wiped the dust from the window and stood on tiptoe to look inside.

Through a tent full of fox dogs, he saw the remains of furniture scattered on the floor, garbage everywhere, and a brown spider the size of a saucer hidden in the crack in the top corner of the window, and the whole house looked like a haunted house.

"I have the impression that this shop has been idle for more than ten years and has not been used. Lupin explained, "A lot of people have speculated about whether there is something wrong here, so it has been idle, but I didn't expect it to be the property of the Black family!"

He drew his wand and knocked on the wooden door of the shop, and with a pop the door opened.

Almost as soon as the door opened, a large amount of dust was splashed.

Everyone hurriedly covered their noses and took several steps back.

Seeing an unexpected intruder, a frightened rat scurries past the house and squeaks in the shop.

They walked in, leaving clear footprints on the creaking floor.

The shop's décor is in keeping with the Black family's usual luxury, with shabby furnishings made entirely of precious mahogany and teak.

Perhaps because of this, it is also a place where thieves frequent.

Everything of even the slightest value in the shop has disappeared or been destroyed, and the remains of all kinds of ornate decorations and furniture are scattered on the ground.

The back windows were also broken, and a cold wind blew in, and it was not surprising that the thieves climbed in from there.

From the outside, it's bad enough, but up close on the inside, it's terrible.

If you want to use it and open it to the public, you have to buy new ones for almost everything.

"It's going to take a lot of work to clean up this place!" Hermione wrinkled her nose and pulled out her wand and whispered to a rug, "Clean it up!"

Pink soap bubbles immediately appeared on the carpet, but it didn't work, there was too much dust, and the bright soap bubbles instantly turned into black goo.

Hermione waved her wand reluctantly and recited the incantation a few more times.

"Don't waste your efforts, Hermione, throw that rug away. Evan covered his forehead and said, "You can buy new furniture and office supplies, but you're right, this place does need a big cleaning, and it's a lot of work!"

"This house has been empty for many years, and there are many things growing in it, so you must be careful when cleaning it. Lupin leaned down in front of a cabinet, peeked through the keyhole and said, "It seems to be a Boggart in there, and it is better to let him out before cleaning this cabinet." ”

"It's crazy to clean out a house that has been abandoned for more than 10 years, and I don't want to spend the rest of my Christmas holidays here. Harry stepped down from the upper floor, gasping for air, "This shop is much more spacious than it looks from the outside, there's a lot of space up there, and there's a lot more rubbish and stuff than here." ”

"Don't worry, Harry, I reckon three days should be enough time for us to get Dobby and Kreacher to help, house-elves are very good at this. Evan also went upstairs and looked around, nodding in satisfaction, "When you visit Ron later, you can also ask the Weasleys to help clean up." I had the idea that the second and third floors would be enough for the newspaper headquarters, and the first floor could be used for something else, such as selling Fred and George's joke products."

"The two of them will be happy that since last semester, they've been doing owl mail order service on campus!" said Harry, "and the products they've developed are very interesting and popular." ”

"It's also very dangerous, and disgusting!" Hermione said disapprehantly, "Look what they did last semester to make a big egg that can be controlled remotely, and it stinks all over the hallway, and the big is hard to clean." ”

"That's something Filch needs to worry about, and they haven't used anything like that anywhere else in the school except outside the Slytherin basement. Evan said humbly.

He didn't dare tell Hermione that the birth of the remote-controlled poop egg was actually his suggestion. The theory used, how to activate the big dung eggs and obey the user's command, was inspired by Hermione's newspaper article on Transfiguration.

"There's a lot of space for a lot of counters, and in addition to Fred and George's joke products, you can also sell other things that the little wizards have researched. Seeing that Hermione still wanted to continue talking about the joke product, Evan hurriedly said, "For example, the potions made in our Potions class, except for a little to take out and use Snape to score, all the rest are thrown away, it is too wasteful, it can be put here for sale, and the price is much lower than the normal market price." ”

"That's a good idea, if Snape agrees with us. Harry interjected.

He would agree, those potions were made by the students themselves, and he had no reason to refuse. Evan walked down and took a closer look at the first floor of the shop, thinking about future planning and design, "In addition to potions, everything that the little wizards make themselves can be put up for sale here, the more the merrier." This matter can be publicized through the Hogwarts Ministry of Magic, which should attract a lot of attention. (To be continued.) )
