Hogwarts: The Cat Wizard of the Moving Castle

No one knew when Nagini set out. One day after the farewell party, she disappeared without a trace.

Perhaps Aberforth knew what day it was.

Because that day, he saw a clean bar, new rags, a sheep pen that had just been cleaned, and clean sheets hanging in the backyard.

This means that she is gone.

Time gradually comes to October, and life seems to be back on track, nothing has changed.

Of course, that's not entirely true.

Neville loved to write letters to his grandma, sharing with her all the little troubles that happened in school. He also asked his uncle to come and hope that he would supervise his grandma and not be picky about food.

Mrs. Longbottom was furious about this. She had always been in charge of Neville, but now she was! Actually - this is simply the opposite of Tiangang! !

However, from the fact that Professor Marchban wrote to Neville, hoping that he would tell her grandmother to stop showing off her great grandson, we knew how Mrs. Longbottom felt about this matter.

Hermione joined the morning exercises. Hermione was not very willing to come before. After all, if she had such time, she would rather focus on studying.

But when Harry curiously asked why Hermione was willing to come to morning exercises, Hermione just said: "If I don't even grasp this time, I don't know how much time I will have to spend with you." together."

Harry felt very sorry about this.

He has really been pressed for time recently, which has resulted in him communicating a lot less with his friends.

Maybe I should find more time to talk to my friends? he thought to himself.

What he didn't know was that the little witch opposite him was thinking the same thing.

But - after the recent homework.

Now we have reached a critical period and we must not stop.

He's going to start experimenting with in vivo subjects.

After the first Duel Club meeting in October, he approached Fred George.

"Hey, good buddy, what brought you here?" Fred said.

"Aha, do you want some experience in doing bad things?" George smiled slyly.

"To be precise, it does matter, but no!" Harry smiled.

"I plan to find an empty classroom again, but there are not many classrooms left. You know, many of their trysts and love affairs will occupy a lot of empty classrooms." Harry said: "And because of some magical studies recently, I hope that I can find an empty classroom that no one will go to."

"Ah! You want to find an exclusive classroom by yourself!" Fred laughed.

George said: "You finally realized that you are going to do some shameful things, my dear heir of Slytherin!"

Harry smiled helplessly: "Normal! Normal magic research!"

"Understood! We all understand!" George said, hugging him and secretly giving him to Nat: "In short, when you become the boss of the magic world, don't forget to treat me as a minister."

"Better say goodbye." Harry could only shake his head: "Seriously, do you have the resources? The most important thing is that no one else will go in. It's best... like your exclusive room!"

Fred thought about it seriously, and after a moment, he shook his head helplessly.

"This... really doesn't exist."

"You know, a breakup is better than a wedding! Now those couples are so fed up that they have taken up all the classrooms. Well, you guys, Slytherin has two permanent classrooms. If you ask yourself, maybe they are willing to give you a favor. .”

"Ah this." Harry had already thought of that embarrassing scene.

Suddenly, George clapped his hands!

"There really is one!"

Fred looked at George and reacted, then nodded: "This is really no problem, yes, that's it!"

"Which one?"

"A place that only a few of the few know, come with me!" George waved his hand directly and led Harry up the stairs.

Along the way, they quickly passed the fork that turned toward Gryffindor Tower and continued walking upward.

"Ravenclaw's territory?" Harry was a little confused. The empty classroom above was indeed a classroom used by Ravenclaws a lot, and they respected each other for long-term use by others.

Because you don't know what weird research attempts those guys in Ravenclaw are doing.

"No, those guys never knew there was such a treasure land next to them!" George said.

"That's where we used to hide things, and it was safe. But later we felt it was too far away, so we moved everything to the classroom on the second floor." Fred explained.

"It's on the eighth floor."

The Gryffindor lounge is on the eighth floor, but that's the tower, and the gateway to the castle is on the third floor.

If you put it that way, it is indeed far enough.

"Let's take you to explore the road first." George said.

Soon, they arrived at the eighth floor.

The eighth floor was very quiet. There were no classrooms for classes here. Under the leadership of George Fred, the three of them quickly came to an empty corridor.

It was really empty, with nothing but the tapestries used as decoration.

There are very few magic paintings.

The tapestry shows a bunch of trolls in tutus, holding large sticks or bone sticks in their hands, surrounding a poor man, smiling ugly.

"Troll beats silly Barnabas!" Fred said: "I would like to call it the top three ugliest paintings in Hogwarts. I hope you are deeply impressed by it."

"It's hard not to be impressed by a bunch of trolls wearing pink tutus, blushing, smiling and armpit hair."

"That's good!" George laughed, then pointed to the white wall.

"Look there, the white wall. I went over there and chanted about the classroom you wanted, three times!"

Harry nodded, followed George's instructions and walked over, and then began to whisper.

"I want a classroom where I can do magic experiments."

"I want a classroom where I can do magic experiments."

"I want a classroom where I can do magic experiments."

Then, the white wall in front of him seemed to twist, and the next moment, a door appeared.

Harry looked back at Fred George in surprise, only to see the two of them nodding towards him.

"this…"

"A response to any request?"

Thinking about it, he pushed open the door and walked in.

The room is not big, with a magic training dummy, several tables, and a shelf.

On the shelves, there were many bottles and jars, as well as dried toad corpses. One jar contained an eyeball of an unknown object.

"Look at the dust. It seems that no one has been to this research classroom since we left." George walked in, lightly wiped his fingers on the table, and then pointed his dusty fingertips towards Harry.

"This is called the Room of Requirement. As long as you have your needs, you can stand in the corridor and recite silently three times, and then this invisible classroom will generate a room according to your requirements." Fred said.

"Generated on request?" Harry looked at the two of them in surprise.

"Don't think about it, there are some things... we have tried it." George smiled.

"I originally said that it would give me a classroom full of gold galleons, but it ended up giving me a study room."

"I guess it wants to tell you that there is gold in the book?" George smiled.

"In short, it can only give you a certain type of room and classroom, but it can't give you a room with anything!"

"What you put forward must be needs, not conditions. This is the core rule we have explored."

Harry looked around the classroom quietly, feeling as if he had found a treasure.

"Thank you," he said. "This classroom is perfect!"

"As long as it's useful." Fred nodded, and then smiled: "In addition, we also have a favor for you to do."

"You can just say it." Harry nodded seriously.

"You...can you go and lie to us, no—just give Percy some advice." Fred said, "We want to apply for a venue to show movies."

"Have you finished the projector?" Harry's face showed surprise. Although he knew that this was not the first time that they had passed Hogwarts' anti-technology curse, in such a short time...

Simply appalling!

"Yes, yes." George nodded: "But Percy seems to be stubborn. We need his status as student council president to help us apply for permission...otherwise...he will never be able to get on the stage."

"We also plan to teach those magical Muggles a lesson. We secretly watched several movies, and it was so exciting!!" Fred said.

"This..." Harry thought for a moment.

"Why are you looking for Percy?" He smiled.

"If not Percy, who should we look for? Directly to Professor McGonagall? We will definitely be taught a lesson by her..." George said helplessly.

"Actually, this is a bit against the Muggle property management regulations." Fred also said.

"Who cares, Colin still holds a camera every day - no, cameras and trains are all creations of ordinary people." Harry waved his hands indifferently, and then said: "Why don't you go find Professor Jones? Why don't you go find Professor Jones?" Professor Boubaji, who has Muggle studies, should have corresponding methods to circumvent the regulations of the Ministry of Magic."

"Professor Jones?!" Fred George looked at each other.

After a moment, they seemed to have thought of something.

"Harry, you are such a genius!!" Fred laughed.

"The professor shouldn't have left yet! He just finished his dueling class!"

"Let's stop him! Quick, quick, quick!"

With that said, the two of them disappeared without a trace without even saying goodbye.

"ah"

Harry was stunned for a moment, then walked to the door and closed it.

Then started cleaning.

After a while, a flat glass plate was spread out on the clean tabletop.

After disinfecting it with alcohol, he placed a red-colored white mouse on the glass plate and gently brushed his fingers over the pitted skin.

The next moment, the petrification spell acted on this little guy.

It’s unfamiliar to prepare skin, unfamiliar to draw rune marks, unfamiliar to drink alchemy magic potion for mice.

Then, he took out a bag of blood.

This is dragon's blood, sold in Diagon Alley.

Connect the infusion tube and perform blood conversion.

Prepare the carving knife to anchor the rune.

Although this was an impatient attempt, he didn't panic at all when he actually started taking action.

In the words of Uncle Mu En, fear and confusion are always the biggest obstacles for novices.

Knowledge and experience are secondary.

Along with the transformation of blood, a kind of fluctuation similar to magic power gradually appeared from the body of the white mouse.

It even broke free from the petrification spell Harry set on it to a certain extent.

Its limbs were trembling, as if it was suffering great pain.

"S-001, weighing 108g, was fed 5g of medicine, and the recipient developed convulsions and tremors when the blood donation conversion progressed to 2/1."

Accompanying his whisper, a shorthand quill flew rapidly on the notebook beside him.

"The receptor has experienced magic power fluctuations. Immediately register A, the conversion rate of the remaining blood will be reduced, and the receptor will be enchanted simultaneously to guide the magic power!" As he spoke, he summoned the hand of the mage, grabbed the knife, and pointed it at the mouse On the side of the body, magic pattern carving begins.

The rat's convulsions became more violent.

At this time, he did not dare to cast the petrification spell on the other party rashly, so as not to change the blood flow rate in the other party's body.

On the glass plate, a few extra filaments appeared inexplicably, grabbing the white mouse tightly.

Time passed slowly until late at night.

This experiment ended in failure.

Harry wiped the sweat from his forehead and kept the mage's hands performing such delicate operations, which was extremely taxing on his mind.

However, the information collected this time is indeed enough.

"I shouldn't have used dragon blood." He sat at the table and analyzed his failures bit by bit.

"Although the guinea pig is known as the universal experimental target, perhaps in terms of magic, the gap between the two is still a bit big."

For the next experiment, maybe we can change to some more common, weaker and ordinary magical creatures.

"A swallow-tailed dog?" He couldn't help but think, and then shook his head: "Apart from having a swallow tail, a swallow-tailed dog is no different from a dog in other aspects."

"Civet? Salamander?" He couldn't help but think.

"No, it's best if they have some similarities in terms of population."

Writing, uninterrupted writing, even if they are just his own thoughts, he has already developed the habit of recording, even if they are just some tentative ideas.

"Mortla?!" This answer suddenly popped into Harry's head.

This is a magical creature that looks like a mouse. It has a sea anemone-like parasite on its back, and the rest of its body looks like a hairless pink mouse. It is often found in coastal areas.

The UK has it! , it is not difficult to get it.

Moreover, although this little guy doesn't look powerful, he doesn't have any powerful or special abilities.

However, no one would want to mess with this little guy.

Because people bitten by it may suffer from symptoms of retching in mild cases.

But this is a milder condition!

If the situation is more severe, the patient's anus will emit sparks, which can last up to forty-eight hours!

Horrible.

"That's it!" Harry quickly finalized the general process and ideas for the second experiment.

After doing all this, he stood up and stretched.

On the other side, a moment before Harry began his experiment.

Mu En looked curiously at the two panting children in front of her.

"What's the matter? Mr. Weasley."
