Became good friends with the Boy Who Lived

Sirius waved his wand a few times, and a ball of rope appeared, tying Peter Pettigrew tightly.

"If you dare to turn into a mouse again," Sirius said viciously, "I will kill you immediately without any hesitation..."

Harry helped Ron up, and Sirius returned Ron's wand to him, saying sheepishly, "I'm sorry, kid, I admit that it did hurt a little bit..."

Ron took the wand and said indignantly, "It hurts a little? You call it a little? You nearly ripped my leg off!"

"Actually, I quite like being a dog," Sirius changed the subject abruptly. "I can tolerate the hair all over my body, but those fleas are a nightmare."

Sirius walked to Professor Snape to check on him and found that he had just fainted. He snatched the wand from his hand roughly and ignored him.

"Sirius, we need to carry Severus outside..." Professor Lupin said suggestively, feeling a little reluctant.

"That's not necessary," said Sirius irritably, "Just let him sleep here for a while, he won't die."

"Come here, Crookshanks," Hermione called out. Crookshanks, who had been watching the show on the big bed, meowed, jumped into Hermione's arms, and purred in satisfaction.

Several people walked out slowly. Peter Pettigrew walked in front, sobbing all the time. Professor Lupin followed behind him, pointing his wand at Peter's back to prevent him from doing anything tricky. Aries and Harry held Ron on each side. Sirius walked silently beside Harry, seeming to be hesitant to say something. Hermione walked at the end, holding Crookshanks.

"Harry," Sirius said with difficulty, "I'm really sorry about your parents..."

"Stop it," Harry said uncomfortably, "I don't blame you. It's not your fault."

Sirius said hesitantly, "You... you know? James asked me to be your godfather, just in case something happens to him, that is... I actually have custody of you, if I... you know... regain my freedom, I want to fulfill my responsibilities and obligations..."

"Really?" Harry said in surprise, "I can live with you? Where is your house? Never mind, it doesn't matter. Even if I go wandering with you, it's better than staying at the Dursleys'."

"Oh! I see!" Sirius showed an ugly smile, "I thought you would be unwilling, after all, I am in such a terrible state now..."

"Don't be ridiculous," said Harry excitedly, "I'd do anything to get away from the Dursleys..."

Aris said quietly on the other side, "Harry, whether you like it or not, you must return to your aunt and uncle during the summer vacation and live with them for at least half a month. Only in this way can the protective magic your mother left on you take effect. You can't let your mother sacrifice herself in vain because of your willfulness."

"What's going on?" Sirius asked in confusion.

Aeris sighed and said, "We can only guess what happened. Before being killed by Voldemort, Harry's mother felt that she could not escape death, so she used her own blood and life as a medium to cast an extremely advanced protective magic to protect Harry from being harmed by Voldemort. Voldemort was eventually wounded and lost all his power. Harry's mother's protective magic can protect Harry until he reaches adulthood, but Harry must live with his blood relatives for at least half a month every year, otherwise this protective magic will lose its effect in the following year..."

The rest of the journey was somewhat silent, and for a moment no one was in the mood to talk.

When everyone climbed out of the tree hole, the Whomping Willow instinctively wanted to attack everyone. Sirius impatiently kicked a scar on the tree trunk, and the Whomping Willow seemed to be cast under a spell and stood still.

It was already getting late, a small cloud covered the moon, and the stars in the sky were shining brightly. Just when everyone was thinking about their own things, the cloud covering the moon slowly drifted away, revealing a big, round ~ full moon.

Professor Lupin, who was escorting Peter Pettigrew, showed a look of horror on his face, and then his expression became ferocious.

"Ah~" Professor Lupin screamed in pain. Sirius rushed forward regardless and hugged Professor Lupin who was transforming.

"Remus... Remus..." Sirius shouted, trying to awaken Professor Lupin's reason, "Don't lose to yourself... This you is not the real you... Don't let the beast's mind take over your body... Remus... Remus..."

Professor Lupin's tattered robe was torn apart, and with a roar like a wild beast, Sirius was freed by Professor Lupin and fell into the grass.

Professor Lupin's human features disappeared, and a creature with black hair, a wolf head, nearly ten feet tall, and able to walk upright appeared in front of everyone.

The creature seemed to still have some rationality. He curled up there. Hermione was terrified. She hugged Crookshanks tightly in her arms.

Peter Pettigrew turned around and smiled mysteriously at Aeris and Harry. Harry raised his wand and pointed it at Peter Pettigrew, but it was too late. Peter Pettigrew turned into a big rat and disappeared into the bushes.

Professor Snape stumbled out of the tree hole. He seemed a little confused. He saw Harry and said through gritted teeth: "Potter! So you are here..."

"Awoo~" A long wolf howl was heard. Professor Snape turned back subconsciously and was shocked to see Professor Lupin transformed into a werewolf. He quickly protected his four students behind him.

"Go back to the tree hole, quickly!" said Professor Snape without allowing any refusal.

The werewolf approached Professor Snape and the others step by step. A big hound rushed out and fought with the werewolf. Sirius turned into a big black hound, while fighting with the werewolf, he led the werewolf away from Harry and the others.

"Sirius!" Harry yelled anxiously and rushed out regardless of anything. Professor Snape shouted anxiously: "Potter! Come back here..."

While Professor Snape wasn't paying attention, Aris rushed out after Harry, with Professor Snape roaring behind him.

Aris and Harry ran as fast as they could towards the direction where the hound and the werewolf were fighting. They saw from afar that the werewolf was gaining the upper hand and the hound was about to give up.

"Eris...Eris..." Harry's eyes turned red with tears, "You must have a way...save him...save Sirius..."

Aeris gritted his teeth. After accepting Rowena's inheritance, he also digested part of Helga and Salazar's inheritance. He had a feeling that as long as he wanted, he could turn into any animal. However, he had never experimented with it, so he didn't know if there would be any bad consequences.

"I can't care about so many things..." Aeris's teeth were clenched, and he became ruthless and activated the transformation magic that he had never tried before.

Aeris' whole body was emitting a black light, and he transformed into a black cheetah about ten feet long. The black panther rushed towards the werewolf like a black lightning.

Just when the werewolf was about to give the hound a final blow, the black panther arrived and pushed the werewolf aside. The black panther rolled on the ground and quickly took a defensive stance.

The big black hound turned back into Sirius, who lay on the ground gasping for breath. Before they knew it, they had arrived at the edge of the Black Lake. Harry also arrived breathlessly and stood by Sirius to check on him.

The roars of beasts continued to come out from the mouths of the werewolf and the black panther. The black panther (Eris) knew that if he showed the slightest bit of cowardice, the werewolf would attack him violently.

The black panther confronted the werewolf for a while, and the werewolf became timid first. After a wolf howl, the werewolf turned around and ran towards the forbidden forest.

Aris was a little confused. How could he be so intimidating after turning into a black panther? He soon found out that he was wrong, and very wrong.

The vast surface of the Black Lake was freezing rapidly, and thousands of Dementors in the sky were overwhelming and heading towards them.

Aes wanted to undo his transformation and restore his human body, but he turned into a tiger, a lion, a honey badger, and a python, but he could not change back to his original self.

"I really don't know which will come first, tomorrow or the accident!" Aeris thought helplessly.

Harry called out his two patronuses, the stag and the doe, who struggled to resist countless Dementors. Harry's eyes were full of despair, and Sirius lay motionless at Harry's feet, as if he had lost his soul.

Finally, Aeris turned into a lion and used telepathic magic. He roared in his heart: "Friends, help us..." The lion that Aeris turned into roared with all his might towards the direction of Hogwarts Castle.

At the same time, several people in different locations in Hogwarts Castle: Ginny and Neville in the common room, Luna wandering around the castle, Cedric and Zhang Qiu on a secret date, Draco tinkering with potions in the basement... they all looked in the same direction at the same time.

They had a vague feeling in their hearts that Aeris needed help, and they all used the Patronus Charm at the same time.

As the sound of "Expecto Guardian" rang out, all kinds of silver animals flew in the same direction.

Just when Harry couldn't hold on any longer, a silver peacock flew over, and Draco's arrogant voice came out of the peacock's mouth: "You're in a mess, Potter! It seems that without me, you just can't do it..."

A silver honey badger flew over and Cedric's voice rang out, "Harry, we're here to help you."

A silver swan made a sound like Zhang Qiu: "Come on! Harry, don't give up!"

A silver rabbit, an otter, a hound, a horse, and two magpies joined the battle at the same time. The last to arrive was a silver lion, the Gryffindor Lion.

Neville's simple and honest voice came out from the lion's mouth: "Sorry, I'm late..."

Thousands of Dementors were as fragile as paper tigers in front of these dozen Patronuses. The dozen Patronuses drove away all the Dementors with ease.

After all the Dementors were driven away, the Patronuses gradually disappeared, and Harry slumped down next to Sirius, gasping for breath.

Eris was also trying hard to change back into a human body. After trying countless times, Eris finally changed back.

Aesus let out a long sigh and murmured to himself, "Finally I've transformed back. I thought I would have to live as an animal from now on..."

"Harry, are you okay?" Aris walked up to Harry and said. Harry forced a smile and said nothing.

Archer pulled a chocolate frog out of his pocket, tore open the wrapper, and stuffed it into Harry's mouth. Harry chewed subconsciously. Archer stuffed a few more chocolate frogs into Harry's hands, then went to check on Sirius.

He had cast a clever invisible stretching spell on the pockets on Aris's clothes, so they could hold a lot of things without feeling heavy.

Aeris pulled a bottle of potion from his pocket and poured it into Sirius' mouth. After a while, heat seemed to come out of every pore of Sirius.

Sirius suddenly opened his eyes and gasped violently. After coming to his senses, he muttered to himself: "What is so bitter?"

Without waiting for Sirius to say anything, Aeris broke off a piece of the chocolate cauldron in his hand and stuffed it into Sirius' mouth. Sirius chewed it twice, a light appeared in his eyes, he sat up suddenly, snatched the chocolate cauldron from Aeris' hand, and swallowed it in three or two mouthfuls.

"Anything else?" Sirius asked hoarsely.

Aeris took out two more chocolate crucibles and handed them to Sirius, who took them and chewed them in big mouthfuls.

"Peter Pettigrew has run away," said Aeris in a heavy voice, "You must continue to run, Sirius."

Sirius paused while chewing the chocolate. Harry asked in confusion, "Why? Sirius is innocent. We can testify for him..."

"Don't be naive, buddy," said Aris, "Professor Snape will not stand on our side. If you were the Minister of Magic, would you believe the words of a professor? Or would you believe the words of four underage wizards?"

Harry fell silent. Sirius swallowed the last of the chocolate and said, "Arius is right. I can't go back to Azkaban. I want to watch my godson grow up." Sirius looked at Harry reluctantly.

Harry choked up and couldn't utter a word. Sirius held Harry in his arms, patted his back gently, and murmured to himself: "Harry, don't be sad. Those who truly love us and those we love will never leave. They are always in our hearts..."

Sirius let go of Harry and said to Eris, "Thank you for everything you have done, Eris. Thank you to Ariana for me too. I will visit you in the form of a dog when I have time."

Aes nodded and said, "Wait for me here for a while."

Aeris transformed himself into a black panther again and ran towards the Forbidden Forest. After a while, an adult Thestral flew over, and Aeris, who had regained his human body, rode on the Thestral.

The Thestral stopped in front of Sirius, and Aeris said, "It will take you to a safe place. Just make sure you are safe. The Thestral will fly back on its own."

Sirius climbed onto the Thestral's back with great effort, and after bidding Harry a reluctant farewell again, he was carried by the Thestral into the dark distant sky.
