Hogwarts: The Cat Wizard of the Moving Castle.

"Why are you here?" Harry looked at the big dog crossing the road in surprise.

Hedlund looked at the big black dog of unknown origin and the name Harry said before, thought about it, and decided to leave.

"Professor, since it's already dark now, let's not disturb you for now." He bowed slightly and said.

"Okay." Mu En nodded.

"Let's go." Hedlund looked at Draco, then at Neville.

"Mr. Longbottom, do you want to leave with us?"

Neville looked around and finally nodded: "Okay."

The three people in the group said goodbye to everyone at the end, then turned and left.

Draco waved his hand: "I will come again in a while, and then we will go watch movies and comics."

"it is good."

"By the way, I haven't experienced a Muggle wand yet! Anyway, let me talk about it later."

Harry nodded and watched Draco leave.

After they left, Aberforth and the two began to think of saying goodbye. He and Sirius were not strangers, but they had only crossed paths during the Wizarding War.

"Then let's go." Dumbledore said, then nodded slightly to the big black dog that Sirius transformed into.

"Whatever." Mu En said nonchalantly, and then handed Sindel's picture frame over: "Send her back."

"Huh?" Dumbledore tilted his head, as if his hearing was bad.

"She has nothing to do at school, so why don't you take her back to the castle yourself." Dumbledore said at last, then waved to a few children, and the group of people walked towards the alley.

With a muffled sound, an old newspaper floated out of the alley.

At the same time, Sirius finally spoke: "Where have you been? Why didn't you tell me when you came to London? Do you want to go to my house?"

His eyes were intense and made Harry feel a little embarrassed.

In terms of time, he does have time to go all the time.

"Don't waste time, it happens to be dinner time." Sirius shook his tail and led a few people towards the other end of the street.

Facing Harry's questioning look, Moon just shrugged casually, he didn't care at all.

"Go ahead, Harry," Hermione suggested, "Sirius has been inviting you."

"Yeah." Harry nodded and took the lead in following Sirius' footsteps.

The group of people followed Sirius for about ten minutes before arriving in a remote neighborhood and finally stopped in the middle of a small square.

Sirius was sitting next to a piece of messy and barren grass, waiting for the few people behind him to come over. When Harry took a closer look, he saw that the doors of the surrounding houses had gloomy faces, as if they were far away from anyone. The windows of some houses were already broken and shone dimly under the streetlights. The paint on many doors was peeling off, and the front steps of several houses were filled with garbage.

Like the African American community in the movie. Harry couldn't help but think of it.

However, that's not entirely true. As an old townhouse, there is no number 12 here.

Instead, there is a number thirteen? !

This is really weird. Generally speaking, due to the influence of religion and local customs, "six" and "thirteen" are the numbers that are omitted in applications.

But soon, the answer was answered.

"Remember No. 12 Grimmauld Place silently," Sirius said. "When my father lived here, he took every precaution known to the wizarding world about keeping it secret. The house cannot be plotted on a map, cannot be Simply see it.”

"Do I also want to read the name of this place?" Sindel asked Mu En quietly: "I didn't see anything either."

"I don't know either, but just say what you want to say." Mu En said softly.

After Mu En finished speaking, the little girl in the painting clasped her hands in front of her chest and began to recite Number 12 Grimmauld Place in a low voice.

At the same time, Mu En was also feeling it carefully while chanting.

A less magical explanation is that this voice is like a key. When it vibrates gently in the air, it seems to coincide with a certain vibration frequency that is spreading around.

Then, the right key opens the right lock.

A tattered door appeared between No. 11 and No. 13, and then the space in the middle began to stretch out like gooey cheese between pizza slices.

But in the blink of an eye, dirty walls and gloomy windows also appeared, and it looked like an extra house suddenly expanded, forcing things on both sides out of the way.

The eyes of the two young wizards widened, and they were obviously very surprised. The stereo of No. 11 was still ringing dullly, and it was obvious that the Muggles living inside didn't feel anything.

"Let's go." Sirius took the lead and walked towards the door.

The stone steps were somewhat tattered and the gaps were full of dust. The black paint on the door was peeling off and covered with scratches on the left and right. Harry also noticed that the silver door knocker was in the shape of a coiled snake.

There was no keyhole or mailbox on the door. When Sirius walked in, he stretched out his paw and knocked on the door in a regular rhythm.

After a while, the door opened and Lupine appeared. He was still the same as before, and his whole appearance looked a bit old.

But the mental outlook is obviously not a little better.

"Oh my god." Lu Ping looked very surprised: "Why are you here suddenly? Come in quickly."

With that said, he quickly greeted a few people into the house.

The house opened into a long and narrow corridor. A row of old-fashioned gas lamps on the wall lit up, casting a swaying and unreal light, illuminating the long and gloomy entrance hall.

Several people gradually walked towards it, and Mu En was sure that if Sirius and the others hadn't been back for a while, making the place more humane, otherwise it would have been directly defined as a haunted house.

Walking into the living room, peeling wallpaper and polished and frayed carpets come into view. A spiderweb-shaped chandelier above the head is flickering, and some portraits blackened by age are hung crookedly on the wall.

Harry took a look and saw that the chandelier and the candlestick on a rickety table nearby were both made into the shape of a large snake.

This design concept

Sirius had transformed back, wearing a long black and red woolen coat and some beard with long curly hair. He noticed Harry's gaze and then explained: "The entire Black family, except me, are all pure-bloods."

Harry nodded understandingly.

"The traitor to the family."

A sharp voice sounded quietly. The tips of Mu En's ears jumped, and then she looked following the sound.

It was behind a curtain. Mu En raised it slightly, and the curtain unfolded quietly like a smart curtain.

A short figure appeared in everyone's eyes. Sirius noticed Mu En's actions. He wanted to say something, but he didn't know what Mu En meant. There was only embarrassment in his eyes.
