The wizard in Hogwarts is unscientific

In the woods near Privet Drive, a dirty big black dog stood on the edge of the woods, looking far away in the direction of No. 4, Privet Drive, with a pair of human eyes. He seemed to be expecting something.

Are you expecting Harry to show up?

A fat orange cat squatted in the shadow of the corner, staring coldly at the big black dog.

Dirty, cruel, cruel, crazy...

Andy felt a lot of negative emotions from the big black dog. How should I put it? Should I say that he is truly the most brutal Death Eater?

Andy felt that Sirius deserved this title.

He escaped from Azkaban and came here alone, just to get rid of his master's biggest enemy-Harry Potter!

But Andy still had two questions in his mind.

The first question: If Animagus can ignore the perception of Dementors, then why didn't Sirius escape from Azkaban until now?

He could have escaped earlier.

Is it because I don't know this, or because I'm not skilled enough in animagus transformation to accomplish it without a wand?

If it's the latter, then Andy can only say that Sirius is really terrible.

Even though he was imprisoned in a hell-like place like Azkaban, he still did not give up or despair. Instead, he silently practiced Animagus alone in the cell, just to one day be able to escape from that place.

The second question: Sirius has been to Privet Drive for some time, why has he not taken action?

Is it because the house has magical protection?

Andy thought to himself: "Since Dumbledore can safely let Harry live in his uncle's house, there must be some reason. And it is impossible for Dumbledore to protect that house without magic."

Is this why Sirius didn't attack Harry?

Is he waiting for Harry to take the initiative?

Andy hesitated.

If Sirius was a vicious Death Eater, then Andy could do any cruel thing to him without any psychological burden.

But if he has something else to hide...

Then Andy will neither mind his business, nor really do anything to him, nor will he send him to the Ministry of Magic in exchange for a bounty.

Andy will just pretend that he never knew about it.

"Well... no matter what, let's arrest him first. If he really has something hidden, we will find out after interrogation."

Thinking of this, Andy no longer hesitated.

The orange cat walked out of the shadows with gentle steps. The sun shone on its body, and the orange cat shook the fat and hair on its body like a physiological reaction.

Cool--

Fuck (a plant)!

Andy cursed secretly and walked towards the big black dog calmly.

Sirius was alert!

He's an animagus shapeshifter himself, so he doesn't look down on any animal.

What's more, since escaping from Azkaban, in order to obtain information from the outside world as quickly as possible, he has read many newspapers, and naturally also read the most authoritative "Daily Prophet" in the magic world.

He recognized Andy.

The "Daily Prophet" reported on this Animagus shapeshifter - Andy Collins, a talented little wizard who should be in the third grade when school starts.

Has it been discovered?

He is really a smart little wizard, much better than those useless Aurors in the Ministry of Magic. At least he knows how to stay near No. 4 Privet Drive.

Sirius didn't want to hurt the child. He felt that it was time for him to leave. Even if his Animagus form was exposed, he could hide himself in another way.

If he wanted to, those Aurors would never be able to catch him!

The big black dog bared his teeth and let out a few low growls. He tried to intimidate Andy and get him to leave.

Andy looked calm on the surface and slowly approached Sirius with cat steps.

If nothing else, Andy felt that in this form he was much more advanced than Sirius. After all, there was a saying in the past life: cat master, dog slave...cough!

damn it!

Sirius cursed secretly, gritted his teeth, turned around and ran away.

Andy also speeded up and followed.

The big black dog ran wildly, moving at an alarming speed, going further and further down the alley. Andy followed behind. Even though he was a little fat, he was not slow in running, and the gap between him and Sirius was never widened.

"Wangwu——"

Sirius growled, and he immediately realized that this was not going to work. The fat cat was no slower than him, and he could not distance himself.

Moreover, he hadn't had a full stomach for a long time, and his physical strength had dropped so much that he couldn't hold on for long.

He must be defeated!

Sirius thought to himself, "A cat can never beat a dog! As long as the little wizard is not allowed to use his wand... Yes! As long as he is not allowed to use his wand, he has no chance of winning!"

"I could hurt his legs!"

Thinking of this, Sirius turned around suddenly, let out a dull growl, and jumped towards Andy.

boom!

The fat cat Patronus flew out from behind, hit Sirius hard on the waist, and also used a stun spell at the same time.

Another cat?

As his consciousness gradually sank, Sirius was unable to resist the power of magic. Before he completely lost consciousness, there was only one thought in his mind - I hate cats!

boom!

There was another muffled sound, and Sirius' body hit the wall hard, then fell to the ground and passed out.

The orange cat's body quickly elongated and turned into a human form.

"Well done, big cat!" Andy praised.

The fat cat patronus flew to Andy's side and swung his tail happily.

Andy waved his wand, turning the weeds on the roadside into ropes and tying them to Sirius, and then dispersed the Patronus Charm.

Snapped!

After apparating Sirius to a laboratory near Godric's Hollow, Andy threw Sirius into prison, replaced him with iron cuffs connected to chains, and locked all his limbs.

"You have to be more careful!"

Andy muttered to himself, then turned around and left the prison. He closed the iron door of the prison with a bang and pointed at Sirius with his wand across the prison bars.

The big black dog regained his human form.

"Well……"

Drowsily, Sirius regained consciousness.

here it is…?

Sirius was still a little dazed. He tried to stand up, but he only heard a "clatter, clatter, clatter" sound.

He turned around and took a look and found that his hands and feet were all tightly locked with iron cuffs. The iron cuffs were also connected to chains, and the other end of the chains was fixed to the wall.

This is a cell!

Sirius calmed down quickly.

He was chained, and although it wasn't too uncomfortable, his range of movement was limited. There are iron railings in front of me. The gaps between the railings are so narrow that even children of a few years old cannot get out of the gaps between the railings.

What's more, he was still chained and couldn't reach the railing at all.

Outside the prison, there was a young wizard who was only a teenager.
