The Mysterious Black Cat at Hogwarts

Alchemy workshop on the sixth floor of the main hall

"Macon, what are you doing?" Hermione looked curiously at Macon on the workbench, assembling seven pistons, with a metal pendulum in the middle, and as the metal pendulum began to rotate, the seven pistons moved in sequence. Doing reciprocating motion.

"This, planetary engine, I am going to use magic power as fuel and convert it into thrust, so as to hold up the floating city." Speaking of this Macon, he became energetic, he raised the model, his face was full of fanaticism, "only by alchemy It is still a little bit reluctant to achieve the purpose of floating, and I am going to use a little bit of technology."

"Engine? Are you going to make the floating city into a rocket?" Hermione stared at Macon with wide eyes. "Be rational, it's neither science nor magic!"

"What rocket? You want to go to outer space?" The frenzy on Macon's face gradually subsided, "It's not impossible, but it's temporarily impossible."

Hermione rolled her eyes, do you really have this plan?She turned and left the workshop, passed by the library, picked up some books, and ran to the top floor to read.

Macon scratched his head and plunged into the research. He now needs to create some devices that can collect magic power.

In his vision, the floating city should have a complete energy conversion system. When it lands, it minimizes energy consumption and collects and stores energy. When floating, it can achieve a balance between energy collection and consumption. Only when flying Only then did the real consumption of energy begin.

Sirius Black, who has been living in seclusion recently, will turn into a big black every night, and go to the castle to find clues. His targets are only two, Beauxbaton and Durmstrang, according to the information recently collected from the outside , he quickly aimed at the headmaster of Durmstrang---Igor Karkaroff.

This guy used to be a Death Eater. After he was sent to the Wizengamot Trial Court, he confessed a lot of Death Eaters, so he was released. Sirius knows that dogs can't change the truth of eating shit, bah bah Pooh!Nature is hard to change!It is the truth that nature is hard to change, so he is always trying to find a way to keep an eye on Karkaroff.

The other party lived in Slytherin's dormitory, so he didn't dare to go too deep. Fortunately, after a long period of exploration, he found that Snape seldom came out to wander around recently. After finishing work and returning to the potion office, he never went out again.

As a member of the robbers, Sirius Black naturally knew every corner of the castle like the back of his hand.Today he was still the same as before, sneaking past Snape's office to the door of Karkaroff's dormitory, lying on the old-fashioned door lock, watching him through the keyhole.

The other party is still the same as before, occasionally practicing black magic, and there is no other abnormality. This is the same as Sirius's thinking, and his nature is hard to change.

Sirius, who found no useful clues, was inevitably a little downcast. When he was about to return to the hut and passed Snape's office, a slight sound reached his ears, and the paw he was about to take froze in mid-air.

etc!What did he hear?Lily?It was Snape's voice!The black dog lay on the door lock of the office like lightning, and what he saw through the keyhole shocked him extremely!

"My God! Lily? No!"

What he found made him bark uncontrollably, escape!That's the only word in Sirius' mind!He was very fast, the black dog's four legs turned into afterimages, he ran desperately, but Snape was faster than him, a puff of black smoke chased after him and blocked in front of him.

"Black!?" Snape looked at the big black dog in front of him after showing his figure, "Are you spying on me?"

"Snape! What kind of magic is that?" Sirius disarmed the Animagus and asked Snape, "That's the black magic of Death Eaters!"

"Stunning!" The answer to Sirius was not Snape's explanation, but a Stunning Curse, the red one fast and hard.

When Sirius saw Snape raising his wand, he quickly turned into a black dog and wanted to escape, but the stun spell was too fast, and after being hit, the big black dog was kicked up and hit the wall, falling asleep past.

With a gloomy face, Snape stepped forward, grabbed the black dog's tail, and dragged him back to the office.

Sirius woke up leisurely, his Animagus had been released, his limbs were fixed by iron chains on the potion workbench, and a rag was still stuffed in his mouth!He was pretty sure that this rag was what Snape used to wipe the dissecting table!The stench mixed with the blood of various disgusting animals made him almost vomit.

"Black! How dare you break into Hogwarts at night!" Snape's face was full of murderous intent, wishing he could kill him immediately, "And, you also discovered my secret!"

"Woooooo!" Sirius was gagged, and he could only whine.

"Do you want to quibble? Or do you want to say your last words? I'd like to hear that!" Snape took off the rag while speaking, and stuffed it back when he finished speaking!

"Woooooo!"

"It seems that you don't want to live anymore, so I'll send you on your way!" Snape repeated the operation just now.

"Whooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!

Sirius had already scolded Snape in his heart, that rag was so smelly, every time it was taken off, he just wanted to breathe fresh air, and every time Snape finished asking , just blocked his mouth, and didn't want to listen to him at all!

Grief and disgust, mental and physical torture made Sirius struggle violently.

"Oh, you are still very energetic. It seems that Potter's godfather, under the torment of the dementors, has exercised a good body. For the sake of wanting to live so much, I will show you mercy and let you stay. Will."

Snape waved his wand, and the rag from Sirius' mouth flew into the trash can.

"Hoo!~Hoo!~Snape! Who is she? Who is she?" Sirius looked at the well-behaved girl doll standing beside Snape, "Tell me! Snape, who is she?" ?”

"Black, can't you see it?" Snape looked at the doll obsessively, "This is Lily, the Lily who was killed by you!"

"No! This isn't Lily! This can't be Lily!" Sirius stared blankly at the doll, and soon he realized something was wrong. She was too quiet, a kind of quietness that didn't seem like a living person , if he was not often tortured by dementors, which made him extremely sensitive to emotions, it would be difficult for him to find out, "She is not alive!"

"Wait! She's an alchemy puppet? Snape! You! You..." Sirius discovered the truth, but the truth made him speechless. The deaths of the Potters had something to do with him, although Harry forgave But he still couldn't forgive himself.

"How did you become a Death Eater?" Sirius remembered the spell that Snape cast just now, the spell that turned into black smoke and flew, "That is the black magic created by Voldemort! Only the core of the Death Eater Membership magic!"

"How did I become a Death Eater? Yes! How did I become a Death Eater?" Snape's voice was very low, and he raised his left hand, exposing his forearm, which was engraved with the Dark Mark. The wand flicked lightly, and a piece of bloody skin with the Dark Mark was peeled off.

"Severus, you're injured again," the puppet next to him walked quickly to the potion rack and took out the white essence, "I'll help you treat the wound."

Sirius silently looked at Snape's forearm, which was restored to its original state after being healed by Bai Xian, together with the Dark Mark.

"You can ask Dumbledore for the answer." Snape lowered his left arm, "I don't want anyone outside to know what happened today. If you can't, I will kill you immediately! Now, or forever Stay here, or leave my office immediately!"

With a flick of his wand, Shenfeng Wuying severed the chains on Sirius.

"I'm investigating Harry's selection for the Triwizard Tournament..."

"Shut up! Blake! Of course I know why you appeared in the castle!" Snape was extremely irritable!This stupid dog!Are you stupid after being locked up for more than ten years? "If it wasn't for... I would have killed you long ago!"

"Snape, I suspect that person is Karkaroff," Sirius knew who Snape was talking about, and he decided to tell Snape what he found, "I recently discovered that he often uses black magic, He's a Death Eater too!"

"Karkaroff? Why do you think he was arranged to live in Slytherin? Do you think Dumbledore is a fool?" Snape pointed his wand at Sirius, "Get out of my office immediately! I don't want to see it for a moment To you idiot!"

Sirius sighed and walked out of the potion office. The moment his feet stepped out of the office, there was a bang.

The huge force with which the office door was closed knocked him into a stagger. Tonight was not fruitless for him. At least he knew that his investigation was in the wrong direction. Karkaroff did not throw Harry's name into the Goblet of Fire. people.
