Thunder, Storm, Lightning!

The rain grew heavier, and the wind intensified.

Dark clouds pressed down on the horizon, and the underground forest swayed precariously. Even the giant redwoods struggled to withstand the gale, shaking constantly.

No one had expected the rain to be this heavy.

Even though they weren't far apart, they couldn't see the person standing on the cliff anymore. They could only catch a glimpse of them through breaks in the rain.

Mu En stood on the cliff, his hands on his chest, feeling his two heartbeats.

Those who practiced the Animagus transformation had to recite a spell at their chest every sunrise and sunset, causing a second heartbeat to appear.

Now, everything was ready. All he had to do was wait.

Wait for a lightning strike!

As he thought this, his gaze fell upon the roots of a giant redwood tree next to the castle. For days, whenever he had free time, he would check the integrity of the formation, ensuring there were no problems with the potion placed within.

Before the lightning strike, the potion could not be seen by anyone.

Just as he was thinking this, the sky brightened, and within the depths of the clouds, lightning flashed.

Mu En reacted with incredible speed. He immediately beckoned towards the redwood, his five fingers forming a bow, his wrist twisting.

From a great distance, the redwood was forcefully dug out, creating a pit.

Mu En pulled his hand back, and the large chunk of wood, along with the medicine bottle previously stored within, flew through the rain and directly into his hand.

Only then did the deafening thunder finally arrive.

Rumble—

He took out the medicine bottle. His pupils narrowed into vertical slits, and he could see that the liquid inside had turned a vibrant blood-red.

Then, he raised his wand, pointed it at his chest, and began to chant the spell.

"Amato Animo Animato Animagus!!"

Thump—thump—

The second heart in his chest suddenly beat violently, and at the same time, his limbs and bones experienced intense stabbing pain.

It was starting!

Silver-white fur began to sprout rapidly on Mu En's arms and fingers. His fingers quickly shortened and became plump. The ring he wore began to be enveloped by the growing flesh, disappearing from sight.

Not just the ring, but even the clothes on Mu En's body began to recede into his flesh, while the growing fur concealed them.

His fingernails became thick and sharp, digging into his skin. His spine began to curve, and his entire body endured immense pain, his body constantly hunching over.

However, this was still not enough!!

Unlike conventional wizards, his body was the ultimate creation of human alchemy. What he sought was not merely to transform into some small animal.

Magic Power began to flow through the alchemical formation on his body. Mu En's body started to emit streaks of silver light, and violent Magic Power radiated outwards from him as the center.

The transformation of the Animagus and the alchemical body, initially in conflict, began to achieve balance under Mu En's conscious guidance, and then gradually transformed into mutual integration.

Mu En's body, in the rain, gradually became slender and smaller.

Rumble—

Another flash of lightning split the sky. A person, a flame, and a broomstick standing at the entrance of Moonlight Castle all saw the figure standing by the cliff.

Even in the sky above, the thick clouds seemed to have condensed into Mu En's face, vast and majestic.

Harry rubbed his eyes, looking in disbelief.

"Hehehe."

Suddenly, the laughter beside him startled Harry. He turned to look, and Lucifer was chuckling, the flame on his body rising and falling, looking extremely happy.

"Mr. Lucifer, what are you laughing about?" Harry asked curiously.

Lucifer extended a small hand and pointed towards the cliff. "If it's still a cat, I'll say the Animagus transformation is useless, hehe."

Harry looked towards the cliff, but it was pitch black. He couldn't see anything.

Just as he was thinking this, a figure suddenly appeared.

A silver-white body, thick mane, and sharply pointed ears standing tall – it was clearly the appearance of a large cat.

"Lucifer, why are you laughing so happily?" Mu En spoke, feeling inexplicably annoyed by Lucifer's cheerful laughter.

"I'm not laughing about anything, hehehehe." Lucifer covered his mouth, his eyes narrowed into slits.

Harry quickly stood up. "Uncle Mu En, you succeeded?!"

Mu En nodded and was the first to jump into the house. Then, a warm whirlwind swept up his body, quickly drying the fur.

It even made it very fluffy.

"Magic?!" Harry was stunned. He quickly recalled his memories. "Uncle Mu En, I remember that Animagus transformations are not allowed to cast spells after transforming into animals! Did I remember incorrectly?"

Mu En landed on the table. "You didn't remember incorrectly, but obviously, there are many mysteries of magic that are not written in books."

Harry nodded quickly. In the first lesson Uncle Mu En gave him, he was told to have dialectical thinking and not to study rigidly.

However, he could also see how powerful Uncle Mu En was, even able to casually break the drawbacks of powerful magic mentioned in books.

This was somewhat beyond his comprehension.

All he knew was… it was strong!

Far beyond what a normal person could achieve.

Mu En rolled over and took a couple more leaps, getting a preliminary feel for his current body. Then, he jumped off the table. The air was quickly disturbed as Mu En returned to his human form.

Though he still had a cat's face on his head.

Even with this advanced Transfiguration spell coursing through his entire body, he hadn't sensed any issue with his head during the transformation.

It was as if he was meant to be a cat-headed human from the start.

"Now you'll listen to me," Lucifer said triumphantly, returning to the fireplace.

After successfully becoming an Animagus, Harry read for a while longer, then cleaned up the water traces Mu En had left when he entered. After that, he bid Mu En farewell and returned to the Dursley Residence.

Mu En sat dejectedly on the sofa, propping his cheek with one hand on the armrest.

He couldn't quite understand why this curse was so tenacious.

His last world trip had been to Porco Rosso, and after that, he'd been cursed and turned into a cat-headed creature.

"Of course, in Porco Rosso's world, this is a curse of the fundamental level," Lucifer said lazily.

Mu En pushed himself up, moving closer to the fireplace. "But Porco Rosso's world had no magic, no history of wizards."

"How should I know?" Lucifer casually picked up a piece of firewood and placed it beneath himself.

"Porco Rosso, or the flying squirrel boss at the airplane repair factory. It's said that in that world, those who go against their true hearts are punished by being turned into animals."

As he spoke, a flicker of memory crossed Lucifer's eyes. "Think about how Porco turned from a pig back into a human."

Mu En also recalled, then said, "He turned back into a human after Fio kissed him, right?

That guy… it's just like a fairy tale, except the story was about a beautiful young girl and an old pig."

"No, no, no!" Lucifer wagged a finger. "You missed the main point!"

"What's the main point?"

"The main point is, Miss Gina was right there.

If you ask me, Porco was turned into a pig because he kept avoiding his feelings for Miss Gina. So, when Fio expressed her love for him, he was finally forced to confront his feelings for Miss Gina. That's when he turned back into a human."

Hearing Lucifer's words, Mu En fell silent for a long time, then said faintly, "So, what you're saying is… I went against my true heart, and that's why I was cursed in that world?"

Lucifer nodded. "That's my guess."

Mu En was somewhat unwilling to believe it; it seemed too ridiculous. When he was in the Caribbean Sea, he could kill whoever he wanted and never mistreated himself.

He had even gone so far as to say, "There can only be one Jones on this sea!" and then killed Davy Jones.

He was so decisive.

"A person in the desert will never realize they are lost," Lucifer said lazily. "You know, the hardest lie to expose is the one you tell yourself.

If you ask me, you should slow down now.

Anyway, this curse won't make you wish you were dead. At worst, you'll have a cat's face. What's the big deal?"

Mu En leaned back on the sofa powerlessly, waving his hand. "Alright, I'll listen to you."
