Hogwarts: Oops, I'm Voldemort

Sirius was leaning on the back of the seat, with his feet crossed on the desk, looking very comfortable.

It was a rare and interesting thing for him to teach his good friend a Defense Against the Dark Arts class for one week every month. Not only could he get along with his godson up close, but the other students in the castle also made him feel very friendly.

Sirius especially liked the Weasley twins. He felt that these two people had the same style as himself and James Potter.

It's a pity that such a happy time only lasts one week per month. Sirius was thinking about whether he should also apply to Dumbledore to be a Defense Against the Dark Arts teacher when the school year is over.

Sirius had also heard the rumor that this course was cursed, but he didn't pay much attention to it. According to Dumbledore, as long as he resigned and left before the end of the school year, there would be no problems.

The more he thought about it, the more feasible it seemed to him. A Defense Against the Dark Arts office was better than his messy home.

"Speaking of home, I forgot to tell Lupine that he should go cleaning with me..."

While Sirius was talking to himself, Lupine opened the door and walked in.

"Why do you want me to clean up with you?" Lu Ping asked gently. There was a faint scar on his face, but it did not make him look ferocious. He always looked relaxed and peaceful. smile.

"Clean my house." Sirius didn't look like he was bothering anyone else at all. He jumped off the chair unceremoniously and hooked his arm around Lupine's shoulders. "You also know the situation at my house. That shabby room has been clean for a long time. There have been people living there, God knows how dirty it is inside?”

"Who's better than the Shrieking Shack?" Lupine asked with a smile.

"Of course it's the Shrieking Shack!" Sirius said matter-of-factly, "That's a famous attraction! How about you going there this time and not being discovered by anyone who comes there because of its reputation?"

Lupine's eyes flickered for a moment, and then he smiled and said: "You also know how long it has been abandoned there. People have long ignored it, not to mention that I won't howl now."

"That's right." Sirius seemed to be sighing, and then said, "Then this weekend, we will clean up the foxy people in the house and clean it completely, so that Harry can come over and talk to him during the summer vacation. We live together.”

"Nice idea."

Sirius patted Lupine on the shoulder:

"On weekends, don't forget, the address is 12 Grimmauld Place. I haven't been back for a long time, I have to go and make some preparations first."

Then he walked briskly out of the office under Lupine's soft gaze.

After Sirius left, "Lupin's" expression became gloomy.

"Let me help you clean up, I really belong to you, Sirius!" Little Barty, disguised as Lupin, sneered, but it was really hard for him to refuse this, otherwise Sirius might become suspicious.

It is said to be the weekend, but in fact it will be three or two days later.

Little Barty received a letter from Sirius on Thursday, and as soon as classes ended on Friday, he came to Grimmauld Place.

"12 Grimmauld Place."

Thinking of this address in my mind, a shabby door appeared out of nowhere between numbers 11 and 13, and then dirty walls and spooky windows appeared, making it look like an extra house suddenly expanded. Get up and squeeze everything on both sides away.

"You actually cast the Loyalty Charm?" Barty thought this was a good gain. It broke the enemy's secret house. Once the war started, Sirius and the others would have one less place to hide.

Little Barty walked up the broken stone steps and stared at the newly conjured door with wide eyes. The black paint on the door was peeling off, and it was covered with scratches left and right. The silver door knocker is in the shape of a coiled snake. There was no keyhole in the door and no mailbox.

Little Barty was still trying to figure out how to get in, when he suddenly heard many loud sounds of metal hitting, and a rattling sound like a chain.

Then, the door creaked open.

Sirius' head was covered with dust, and his handsome hair was covered with white cobwebs.

"You're finally here!" He breathed a sigh of relief as if he had seen a savior. "I've been busy all day, but I still haven't been able to clean a small kitchen!" Then he shook his head and walked away first. Got in.

"Come in, but don't touch anything, I can't promise—"

Before Sirius finished speaking, little Barty accidentally knocked off a piece of cloth on the wall, revealing a huge portrait.

"Beasts! Bitch! Dirty and sinful scoundrels! Bastards, freaks, ugly monsters, get out of here! How dare you desecrate the home of my ancestors -" An old lady wearing a black hat was screaming desperately in the portrait. The screams were loud and tight, as if they were being tortured and beaten.

"That's what I want to say." Sirius shrugged at Lupine helplessly, and then shot back in a very rough voice.

"Shut up, you horrible old witch, shut up!"

The old lady suddenly turned pale.

"You - you are a prodigal, a disgrace to the family, the scoundrel that I gave birth to! How dare you bring such a lowly friend to the glorious and great Black family?!"

"I told you - shut up!" Sirius punched the portrait hard, and then put the knocked down curtain back up to block out the sound. After doing all this, he felt as exhausted as if he had run for several kilometers.

"I probably haven't formally introduced you to you yet, my mother, she just wants me to die."

"It's understandable." Little Barty felt the same, but he was referring to his father.

Sirius rested against the wall for a while, as if he had regained his energy. He clapped his hands and commanded: "Okay, let's start over. I will continue to work on the kitchen. Please go and clean up an empty room so that Harry can come over." There's a place to stay. If you hear something talking in the room, just ignore it. It's a crazy house elf, and sooner or later I'll have his head hanging on the wall!"

It was true that Sirius had ordered Kreacher to come and help with the cleaning, but that guy was obedient and agreed, but in front of Sirius, he put a pile of mud on the kitchen wall. If he hadn't caused the trouble, , Sirius packed things faster.

"It's Kreacher, right?" Little Barty responded and walked upstairs in silence.

The wooden stairs seemed to have been hollowed out by insects. When he stepped on them, they immediately bent and made a worrying "squeak" sound. Fortunately, he went upstairs smoothly and pushed open a room to get the stairs. Raised the wand.

"Whirlwind sweeps away!"

"Clean up!"

"..."

Several cleaning spells were cast together, but the room was still a mess.

The dirt in many places is not caused by ordinary things, but by the footprints left by some magical creatures. This kind of dirt is even more difficult to deal with.

Barty Jr. was busy all night, during which he met Kreacher three or two times. Each time, the other person said unpleasant things, but as soon as Barty Jr. wanted to go over and talk to him, Kreacher would disappear immediately.
