For Sirius Black's solemn salute, Kewen could not accept it with peace of mind.

The reason why he supports the other party so much is because Dumbledore entrusted the other party to him, and secondly, it is actually an exchange that does not know whether to wait or not.

These materials may not be equivalent in exchange for those magic spells passed down by the other party.

But together with the help in times of despair, and the plagiarism plan, all of them may be almost equivalent.

Therefore, Kewen hurriedly stepped forward and raised his hand to help Sirius up.

Sirius, who got up, said some words of thanks to Kewen very excitedly. Kewen finally calmed him down and made him calm down.

Afterwards, the two headed towards 'Hogsmeade Village'.

On the way, Sirius drank the 'compound decoction' and became Kewen's usual face when he went out.

Next, the two went to the 'Screaming Shack' on the edge of the village together, and briefly arranged the room together.

Speaking of which, the reason why this house is called the "Screaming Shack" is actually related to Professor Lupin.

When Lupin was in school, he would come here every full moon night through the secret passage under the 'Battling Willow'.

After turning into a werewolf, in order to control himself, Lupin often bit his arm, suppressing his animal nature with pain.

The pain caused Lupin to scream often, and over time, the people in the 'Hogsmeade Village' noticed it. Therefore, those people called the house the 'Screaming Shed'.

anyway.

After arranging the residence for Sirius, the two went to the center of 'Hogsmeade Village' and arranged a suit for Sirius in the shop.

Of course, Sirius couldn't wear this outfit when he usually played here, so he needed a new outfit.

Only at the end of the plan will he return to his current state of embarrassment so that the plan can be successfully implemented.

These little things were discussed in the principal's office before.

After that, the two had dinner at the 'Pig's Head Bar' in the village. After all, from the afternoon until now, they only had some simple snacks at Dumbledore's.

While eating and chatting, the two returned to the 'Screaming Shack' until midnight.

Sirius will always live here, and Kewen bids him farewell and returns to the academy through the secret passage.

After today's rush, there is no need for Kewen to ask about the next thing, and there is no need for him to participate in any plot.

Therefore, Kewen got enough time for him to continue to master the 'animal transformation'.

In quiet days, Kewen pointed his wand at his heart every day, morning and night, and then recited a series of incantations.

Every day, I can feel the second heartbeat in my body, and I feel that it is beating more and more powerfully.

After more than a month, the thunderstorm weather that Cowen had been waiting for finally arrived.

It's the weekend and it's the day of the House Quidditch Cup.

Everyone ignored the cold and heavy rain and went to the Quidditch pitch, but Cowan did the opposite and hurried to the 'House of Requirement'.

At the same time, Kewen, who was on the way, also sent a message of "patron saint" to the kitchen.

Soon came to the Room of Requirement and began to wait in the corridor.

Not long after, the elf Lili suddenly teleported over, and asked with a look of anticipation: "What is the master's order, Lili?"

Kewen raised his hand and stroked Lili's hair: "I need you to help me master a magic spell."

"Yes! Lili will definitely protect her master!"

"No, it has nothing to do with protection." Kewen explained with a smile: "Just in case, if something happens to me, I need you to take me to the principal."

"Yes! Lili understands! But master..."

A tangled emotion appeared on Lili's face. On the one hand, she couldn't stop Kewen as the master's thoughts, and on the other hand, she was very worried about Kewen's safety.

Seeing this, Kewen said softly, "Just say what you want to say."

"Yes." Lili replied, and then continued: "Master, can you not practice any dangerous spells? Or, when the principal and the professors come back, master, you can practice again."

"There's no need for that." Kewen stared at the wall where the 'House of Requirement' was, shook his head slightly, and reassured: "I have confidence in myself, and I asked you to come here just to add the last insurance."

"Owner……"

Li Li wanted to say something else, but the rainy sky outside the castle was suddenly turned pale for a moment by lightning.

Seeing this, Kewen immediately raised his hand to stop Lili's next words.

He started walking back and forth, saying to himself 'I need a quiet and dark place'.

Soon, the door emerged from the wall.

Amid the belated thunder, Kewen quickly pushed open the door and squatted down at the door after entering the room.

Reaching out his hand in the dark environment, he directly held the crystal bottle in his hand.

Turning around and exiting the room, Kewen was in the light and immediately looked at the crystal bottle in his hand.

The original crystal bottle was filled with his saliva, as well as chrysalis, hair, and a small leaf of the 'Mandela grass'.

But now, there are only less than one third of the red medicinal liquid in the crystal bottle, and everything else has completely disappeared.

Seeing this, Kewen's face showed a look of joy, and he couldn't help but whisper: "It's done!"

Seemingly impatient, Kewen immediately recited in his heart again.

Soon, a fixed practice room appeared. Kewen greeted Lili and pushed in the door.

Walking to the center of the practice room, Kewen took a deep breath after taking out his wand.

Breathing out the turbid air, he turned his head and told Lili, "Remember Lili, you have to take care of me after I transform, and don't let me bump into anything."

Li Li quickly and solemnly responded: "Yes! Master! Lili remembers it!"

"Also." Kewen continued: "If I don't change back after half an hour, you will send me to the principal."

"Yes!"

"Okay, that's it."

After speaking, Kewen brewed for a while, then raised his wand against his heart.

At the same time, he began to recite the mantra he had been chanting every morning and evening for more than a month: "Amado, Animo, Anima, Animagus!"

After chanting the mantra, Kewen immediately opened the crystal bottle in his hand, raised his head and drank the red potion in one gulp.

An icy feeling fell straight down from the esophagus, and after entering the stomach, the icy feeling suddenly turned into a heat flow, and quickly spread to the whole body.

The next moment, a sharp pain suddenly appeared all over the body.

It was as if heard the 'crunch' sound of the bones, as if heard the sound of the muscles tearing all over the body.

Kewen's eyes couldn't help but split.

"Uh-"

He raised his head and screamed out, and in the next moment, Kewen's figure suddenly began to shrink.

The bones of the whole body bulge outward from time to time, and the muscles twist like a twist, shrinking inward.

In Cowen's unbearable scream, his stature became smaller and smaller, until after about five breaths, this terrifying transformation finally stopped.

At this time, Kewen's figure had disappeared, and only a bird with a bright black head, neck, back, and tail, and a white belly remained.

That's a magpie...

The elf Lili has worked in Hogwarts for a long time, so she has seen Professor McGonagall's transformation. After seeing Kewen's state at this time, she immediately understood what magic her master was practicing.

At this time, seeing the magpie that the master turned into was paralyzed on the ground, she couldn't help but ask with great concern: "Master! Are you okay!?"

Kewen felt very weak at this time. After all, the collapsed state of his body was an unprecedented pain.

However, after hearing Lili's question, he wanted to respond with a sound to appease the other party, but unexpectedly what came out of his mouth was: 喳——

Ke Wen was stunned for a moment, and then he suddenly came over. He had already transformed himself, and was no longer in human form.

At this moment, he suddenly noticed that the weakness in his body was rapidly receding, and his strength returned to his body.

As a result, he tentatively wanted to stand up, but unexpectedly couldn't grasp the sense of balance, and just got up, he plunged his head to the ground.

clap clap clap!

Subconsciously reaching out, it turned into flapping wings.

The violent flapping action caused several feathers to fall from his half-black and half-white wings.

After realizing his own situation, Kewen quickly calmed down, first kept the posture of lying on the ground, and then slowly stood up again.

This time, Kewen felt the balance of his body all the time, and under his constant adjustment, he finally managed to stand on the ground.

Afterwards, Kewen opened his wings and turned his head to take a look at them.

Feeling very new to his current state, he tried to flap his wings twice, but his body swayed unbalanced again.

He quickly supported his body with his wings, and after thinking for a while, Kewen closed his Occlumency.

The next moment, a sense of consciousness entered his mind instantly.

Under the collision of consciousness, Kewen was in a trance for a moment, and he couldn't tell whether he was a human or a magpie.

However, Kewen's will was very strong, and he quickly suppressed this feeling of split personality, and the human mind successfully dominated the body again.

But through this collision of consciousness, Kewen instantly grasped all the common sense of the 'magpie posture', as if it was his own instinct.

He tried to flap his wings again, this time there was no sense of imbalance, and he felt the resistance of the air under his wings. With the flapping of his wings, he felt a little fluttering about to fly.

Unable to bear the urge in his heart, Kewen bent his legs, and then jumped up vigorously, flapping his wings continuously at the same time.

In a sound of 'flashing', the magpie that Kewen transformed into flew up smoothly, and after flying out a certain distance, it successfully turned in mid-air.

In the end, Kewen sometimes laughed and cheered loudly, circling the entire practice room.

And Lili's point of view.

She didn't understand if the magpie that the master had turned into was saying something, and the 'chachachacha' that filled the room made her tilt her head in a daze...
