Hogwarts: I am the White Demon King

Sebastian frowned, his body beginning to tremble involuntarily. His heart pounded, as if trying to leap out of his chest.

Then, a sharp pain struck, spreading from the soles of his feet to the top of his head.

Sebastian could clearly feel his bones rapidly lengthening, his muscles expanding wildly within his body, as if every part of him was being reshaped.

His fingertips became thick, his nails turning into sharp claws, and his legs began to lengthen and thicken, supporting a massive frame.

At the same time, his skin became increasingly taut, then cracked, hardening into thick scales.

Each scale's formation was accompanied by a sharp, stinging sensation, but as the scales covered his entire body, the pain was gradually replaced by a sense of powerful strength.

Next, the vertebrae in his back began to deform violently, and wings gradually took shape. The powerful dragon wings, like a giant curtain suddenly torn open, covered the entire clearing.

The massive wings were extremely powerful. Sebastian felt as if he could take flight with just a single flap.

Finally, his head began to transform, his nose and mouth stretching into a huge dragon's maw, teeth emerging like sharp daggers.

His eyes turned into the vertical pupils of a dragon, and his vision began to change. Everything in the distance became incredibly clear, as if he could see every subtle movement within the Forbidden Forest through the rain.

Accompanied by a deep dragon's roar, bright flames, like a sharp sword, tore through the rain curtain overhead, scattering many of the clouds in the sky.

Fortunately, this was deep within the Forbidden Forest, and the teachers and students of Hogwarts would not notice the changes here. Otherwise, Hagrid, familiar with dragons, would definitely brave the rain and head into the Forbidden Forest, searching for any dragons that might be present.

Success!

Sebastian roared inwardly.

The dragon was indeed the right choice.

This massive size, thick scales, and explosive power provided an overwhelming sense of security.

Sebastian couldn't help but want to roar at the sky.

He had completed what Slytherin had not, using Animagus to transform into a true magical creature—a dragon.

Not enough!!

As if influenced by the greedy nature of dragons, Sebastian's ambition began to grow wildly like weeds. He wanted to take advantage of this opportunity to become even stronger.

He thought of a paper he had written last semester, "Speculations on Secondary Animagus Transformations."

【Under normal circumstances, an Animagus can only transform into ordinary animals. This transformation offers limited practical help to wizards.

Therefore, this paper proposes the following hypothesis: After completing an Animagus transformation, is it possible to further apply human transfiguration to transform the form into a beast-man form?

This way, through a secondary transformation, the characteristics of the animal can be added to the wizard's body.

For example, after becoming a dog through Animagus, and then transforming into a beast-man through human transfiguration, the wizard's agility and strength could be significantly increased.

......

】

However, in the existing Animagus transformation process, the animal that the wizard transforms into is no different from an ordinary animal in nature, lacking any magic and unable to use human transfiguration.

The only magic-related characteristic is the ability to undo the transformation and revert to the wizard's original form.

In this context, the hypothesis of secondary transformation remains theoretical, lacking the possibility of substantial verification.

However, things were different now. The dragon he transformed into was a magical creature!

Feeling the magic surging throughout his body, Sebastian felt that this was the best opportunity to verify his theory.

Although the dragon form granted him incredibly powerful strength and magical resistance, his overly large body would make him less agile in many situations.

He needed to find a balance between strength and agility. Therefore, he decided to try to compress the dragon's power into a smaller form, creating a brand new form—the dragon-human form.

Thinking of this, Sebastian cleared his mind, focused his spirit, and calmly recalled the structure and composition of the human body.

Then, using all he had learned, he guided the magic with human transfiguration, beginning to adjust the dragon's body.

It's working!

Sebastian felt the magic surging within him, slowly transforming the dragon's body in a delicate and precise manner.

His dragon claws began to change. The originally large claws gradually shrunk, becoming more agile, but still retaining the dragon's sharp claw tips.

Then, his forelimbs began to stretch, transforming into the shape of human arms. The firm muscles on them gave a sense of explosive power.

As the transformation progressed, the originally broad back of the dragon gradually straightened. His body turned into the size of a human, but his entire body was still covered in hard scales, giving a sense of wildness and power.

His dragon tail disappeared, and his dragon wings gradually shrunk, becoming more compact, like a cloak behind a warrior, which could be unfolded when necessary to help him fly.

Next, his dragon head began to change. The huge dragon's maw gradually shortened, and his mouth became closer to the shape of a human, but still retaining sharp teeth and a powerful bite.

Dragon horns extended upwards from both sides of his forehead, like a crown on his head, exuding majesty.

When the transformation was complete, Sebastian had become a three-meter-tall dragon-human giant.

He lowered his head and calmly observed his new form with those vertical pupils.

Perfect!

Although this body was no longer as large as a dragon, the sense of power was not diminished at all, but instead became more agile and deadly.

He raised his hand and clenched his dragon-claw-like fist. The feeling of power and agility combined made him feel extremely comfortable.

Moreover, what was even more surprising was...

After transforming into the dragon-human form, Sebastian could feel his spell stacks reappearing, surrounding him.

What did this mean?!

This meant that he could cast spells in dragon-human form!

The corners of his mouth gradually widened. This form was the perfect melee wizard form.

From now on, he could learn from Gryffindor, wielding a wand in his left hand and a weapon in his right, sweeping away all obstacles in front of him!

Mia stood aside, gripping her wand, staring dumbfounded at everything before her.

Turning into a dragon at first was pretty normal. The dragon's roar and the flames that shot into the sky made her excited.

However, before she could ask Sebastian how it felt to transform into a dragon, she saw Sebastian's dragon body change again.

This change made Mia's heart shrink tightly into a ball.

What's going on?

Has it failed?

Why hasn't Sebastian sent out a distress signal? Has he lost his mind?

Just as she was worried and preparing to grip her wand and go to his rescue, Sebastian's transformation completely stabilized.

The brand new dragon-human form appeared before her eyes.

This transformation filled Mia's mind with question marks.

What is this form? I've never seen it before?!

Is this how Animagus is used?

If she had to compare it, searching the magical world, perhaps only werewolves had a slight similarity to this form.

Looking at Sebastian clenching his fist, Mia opened her mouth, just about to say something, when she saw Sebastian staring straight at her.

At the same time, a deep voice sounded.

"Mia, raise your wand and cast a spell on me with all your might!"
