Sirius rode a broom, carrying the Mandrake soaked in morning dew and the Hawk Moth, through the clouds and into the moonlight. The magic of the silver moonlight began to have some effect on the materials in the small glass bottle.

It was very cold in the sky above Azkaban, and the icy wind cut through his thin body.

He needed to perform some delicate operations under the moonlight in the sky - he had to put the mandrake into the glass bottle under the moonlight, and then add dew, Cyrus' hair and the chrysalis of the ghost moth.

The order of this process must not be disrupted, otherwise there is a high possibility of magical accidents, so he must be extremely focused at this moment.

After a while, Sirius came back with a glass bottle of potion in his mouth and dropped the broom on the ground.

"Okay, now you just need to put it in a dark corner where the sun doesn't shine. Luckily, there are places like that everywhere."

"Yes." Cyrus waved his hand, and the small bottle disappeared immediately.

"Then you need to wait for the first thunder before the storm comes--" Sirius had only said half of his words when thunder sounded outside the window. Even the lightning could not penetrate the dark clouds. His expression was very helpless.

"This is the worst part. In Azkaban, it's hard to tell which thunder is the precursor of a storm. Don't try to summon a storm with a spell, or it might have a bad effect."

"Don't worry, even if I want to, my spell can't break through this cage for the time being." Cyrus said.

Of course it was possible to break through by force, but Cyrus didn't want to alarm Dumbledore.

"That would be best. Also, don't forget to point your wand at your heart and chant a spell at every sunrise and sunset while you're waiting for the storm." Sirius reminded him, "I don't think you've forgotten the time in the outside world, have you?"

"How could that be? There has always been a clock telling time in my memory. And Malfoy told me the approximate location of Azkaban last time. It is not difficult to calculate the time of sunrise and sunset." Cyrus said, "It is still a few hours before dawn. I'd better tell you about Regulus first."

Cyrus spent about half an hour telling Sirius about Regulus's experience. Of course, he concealed the existence of the Horcrux and the fact that the Horcrux was Slytherin's pendant. He just said that it was something very important to Voldemort.

"You mean, he gave the chance to survive to Kreacher and died in that huge lake?" Sirius' face was full of disbelief.

The Black family actually had such a kind-hearted child. If those ancestors who were proud of their "pure blood" and liked to chop off the heads of house-elves as ornaments knew that Regulus gave the chance to live to a lowly house-elf and was willing to die, they would surely be so angry that even the coffin lid could not hold it down, right? "He is a good boy, but he took the wrong path." Cyrus said softly, "But later he saw the nature of the Death Eaters and immediately turned to the light."

"Where is the cave? Where is the object that is so important to the Dark Lord?"

"Who knows? Maybe Regulus has found a way to destroy it, or maybe not?" Cyrus pretended to be indifferent. In fact, he was very interested in the pendant. Among the treasures left by the four giants, only the power of the pendant was unknown. "If you have a chance, you can talk to Dumbledore about this."

"Dumbledore, huh..." Sirius laughed at himself, "I think if he sees me, he will probably catch me and hand me over to the Soul Eater right away. I'm not afraid of death, but at least I have to kill that despicable traitor first!"

Sirius left in a hurry again. Cyrus wanted to give him the broom, but the guy ran so fast that Cyrus didn't have time to say anything.

It can be seen that he actually cares about the affairs of his "brother", but the most important and urgent thing now is to kill Peter Pettigrew first.

This was not easy. The Ministry of Magic was hunting him down very closely, and even the Muggle world was looking for him. Once he set foot on British soil, he would not even have the chance to transform back into a human. If he was not an unregistered Animagus, he would have been caught several times.

Cyrus felt the humidity in the air and the trajectory of the flow of clouds and rain. Soon, the clock in his memory turned to three o'clock in the morning, and it was almost time for sunrise.

Azkaban is located in the North Sea. Considering the climate here, it should be located relatively far to the north, and the nights in summer may only last five or six hours.

Cyrus was facing northeast, and the clouds on that side seemed a little darker and brighter.

However, in order to avoid mistakes, Cyrus chose to take a small drop of Felix Felicis. Suddenly, a strange feeling immediately lingered in his heart. He felt as if he was very light, and his confidence spread like a devil's snare.

He suddenly felt that perhaps he should change his approach.

The Animagus spell is: Amado, Animado, Animagus, Animagus.

You should use different incantations for different spells. It's impossible for you to have fluorescent lights in your mouth while your wand is shooting the Killing Curse.

"But what if I switch spells?"

This voice kept echoing in Cyrus's mind. It was very tempting, but reason made Cyrus hesitate. The elixir is not a lucky potion, nor is it a panacea. It cannot change the inherent factors of the outside world. All it can do is make you feel that everything is going well.

But the strong premonition in his heart gradually convinced Cyrus.

He raised his wand and pointed it at his heart. A new but vague spell suddenly popped up in his mind, as if a distant voice whispered in his ear:

"—Imagmagus."

In the black world, a big golden bird spread its wide wings! "Boom!"

“Boom!”

A powerful second heartbeat suddenly began to beat in Cyrus' chest, like the sound of a violent drum.

Normally, wizards couldn't feel a second heartbeat immediately when practicing Animagus, but at this moment, the two beating hearts in Cyrus' chest seemed to overlap -

The entire Azkaban was caught in a huge vortex of magic, and the black rock-like clouds began to flow, forming a huge wind wall. It was as if a hole appeared in the sky, sweeping everything in.

A huge eye of the storm appeared over Azkaban. The rising morning light and the moonlight about to fall into the sea slanted down together, covering Cyrus like a light veil.

He suddenly felt the air become more humid than before.

This is a sign of the coming storm.

"boom--"

The first flash of lightning split the night sky.

Cyrus immediately took out the glass bottle. After only a few hours, the mandrake and the hawk moth pupa in the bottle disappeared, and were replaced by a crystal clear, blood-red potion.

Cyrus followed the premonition in his heart and drank the blood-red potion in one breath.

He immediately felt a sharp pain in his body, and the second heartbeat was even stronger than before. He felt as if his body was being replaced by another.

It was a huge bird with golden wings! His handsome face began to twist, his mouth bulged forward and turned into a sharp beak; his ears turned into beautiful feathers on both sides; his hands turned into wings and two pairs of slightly smaller wings grew behind his back; his legs also turned into huge claws...

The huge body filled the entire cell in an instant.
