For wizards under the age of seventeen, especially students of Hogwarts, using magic in front of Muggles is illegal.
Exposing the magical world is a serious crime.
This was fully demonstrated in the Harry Potter movies; the cowardly Minister Fudge only cared about the results, regardless of the cause.
To avoid this problem, Rey had thought long and hard. Transforming into a Black Dragon was the safest method.
Without magic and preparation, vampires are extremely hard to kill. Transforming into a Black Dragon was equivalent to shedding his human identity, rendering the Ministry's monitoring devices useless.
If they were effective, then when he transformed into a Black Dragon at Hogwarts, the Ministry wouldn't have needed to send investigators; the Dragon Research and Control Bureau would have just arrested him directly.
Burning the vampire to ashes—that was the most effective method Rey could think of.
Black Dragons didn't just breathe fire; the blue flame was the highest temperature Rey could currently master.
The jacketed man rolled on the ground, struggling only briefly before stopping. His body burned like dry wood, crackling loudly. Within seconds, his six-foot frame had shrunk by more than half.
Rey, in his Black Dragon form, turned and walked toward Dr. Willy, who was on the verge of fainting. The ferocious appearance and the rotating dark golden dragon eyes felt cold and bloodthirsty.
"What a crazy world..."
Dr. Willy, who thought he was dead for sure, sighed weakly and fainted before Rey could fully approach.

A twelve-year-old child is usually around 1.45 meters tall, and Rey was a head taller than that.
Rey's height was comparable to a fifteen or sixteen-year-old. Combined with his immense strength, the weight of an adult man over 1.8 meters was nothing to him.
Reverting to his human form and picking up the gun from the ground, Rey walked to the unconscious doctor, hoisted him onto his shoulder, and quickly left the scene.
Gunshots had been fired, and sirens were already wailing a few streets away. The police would arrive soon. Aside from some signs of a struggle and a few deformed bullets, Rey believed no other traces would be left behind.
The vampire corpse of the jacketed man should burn to ash before the police arrived. Come daylight, the sun would destroy even the ash.
Rey carried Dr. Willy to the roof of a dilapidated building and poured a vial of potion from his spatial bag into the doctor's mouth.
He had bought the potion in Diagon Alley. Since he planned to rob criminals, getting injured was a possibility, so this was a precaution.
Don't let the small size fool you; it was incredibly expensive. Rey had painfully parted with three vials worth of galleons after selling some items he brought back from a thousand years ago.
They were both pitiful people, both fathers with daughters. Having been a father in his previous life, Rey naturally understood Dr. Willy's actions in shooting the drug dealers.
A vial of Wiggenweld Potion—as long as no bones were broken, other soft tissue injuries should heal quickly.
Sure enough, a major characteristic of magical potions compared to secular medicine was their immediate effect on ordinary injuries.
Not long after, the bald Dr. Willy slowly woke up.
He shook his heavy head as he came to, then looked at Rey in front of him and asked, "Where am I?"
"A rooftop three streets away. I didn't know where you lived, so I had to bring you here."
Rey wasn't old, and his voice sounded like a teenager's. As a doctor, Willy easily picked up on that.
However, recalling the incredible experiences before he passed out, he stared at Rey for a long while before asking suspiciously, "Are you that dragon?"
The question was sudden. Rey hadn't expected him to ask so bluntly.
The difference between a human and a dragon was significant. For someone who had never seen or understood magic, Rey couldn't fathom how he made that connection.
"Why do you say that?"
Rey paused, neither denying nor confirming, but asking back. He was curious how the other party associated him with the dragon.
Moving his still-aching body slightly, Dr. Willy smiled and said, "I don't think any other creature could have saved me from under that dragon's claws, so you must be that dragon."
The shock the Black Dragon gave him was immense. perhaps in his perception, that Black Dragon was the fiercest creature, bar none.
"Thanks for thinking so highly of me. Yes, I am that dragon."
Rey was very generous and admitted it naturally. This caught Dr. Willy, who was sitting against the parapet, off guard. After all, it was just a guess.

His body was gradually recovering, and the potion was taking effect. As a doctor, Willy felt this clearly.
It was magical and surprising. He raised his hands, touching his injured and painful areas. Then, he looked up at Rey excitedly, his eyes filled with hope.
"I know what you're thinking, but this medicine won't have much effect on your daughter's severe injuries," Rey said regretfully. He could naturally see the doctor's thoughts, especially with that hopeful look.
Dr. Willy was disappointed, but not in despair. Rey only said this medicine wouldn't work, not that his daughter was hopeless.
Having calmed down, he decided to clarify the situation first, so he pondered for a moment and asked again, "Why did you save me?"
"I am a wizard."
Instead of answering the question directly, Rey suddenly stated his identity.
Dr. Willy paused for a beat, then asked, "Like the witches in movies?" For Muggles, legends of witches had appeared throughout history, as famous as the Black Death. That was why Dr. Willy asked.
"A wizard who can use magic, but not a woman. You should be able to tell I'm a man."
Rey replied with a wry smile. The expression in Dr. Willy's eyes naturally couldn't escape him. Clearly, regarding the word "man," Dr. Willy at most considered him a boy.
"You still haven't answered why you saved me?" Dr. Willy pressed again. Since the other party was someone capable of magic and spent so much effort saving him, there must be something he wanted.
The "want" here wasn't a plea, but something to be gained. Only after clarifying this could he further ask Rey to save his daughter.
"If I told you I had a daughter in my previous life too, would you believe me?"
Without any intention of joking, Rey said simply.
When a person is serious, every movement and word conveys it fully to the listener.
Regardless of whether the person in front of him looked like a boy or a man, it didn't affect the result. Dr. Willy nodded; he believed it.
"I am Willy Bruce, a surgeon at St. Mary's Hospital." After the initial trust was established, Dr. Willy introduced himself formally and extended his right hand.
"I am Rey MacFusty, a magic apprentice who can transform into a Black Dragon. I hope you can keep tonight's events a secret." Shaking hands was basic etiquette; Rey extended his right hand and said.
"Okay. Thank you for saving me."
"You're welcome! Here, you can take this first. If you trust its effect, you can use it on your daughter."
Rey took out a small vial of potion and placed it in front of Dr. Willy.
"This... didn't you say it wouldn't have much effect?" Surprised that Rey would give him the potion again, Dr. Willy asked doubtfully while feeling happy.
"It won't cure her, but it can stabilize her condition. Afterward, I will think of other ways to heal her," Rey explained.
But he immediately added, "I don't have much of this potion, so don't waste it by analyzing its components."
Doctors are confident and rigorous scientists. Encountering a potion with immediate effects, it was very likely he would take it for research, so Rey gave the instruction.
"I believe you."
Dr. Willy said gratefully. He had seen many things tonight—vampires, Black Dragons—so there was no reason not to believe in this magic potion.
"How can I thank you?" Dr. Willy asked after accepting the potion. Although the person in front of him was a child, his speech and demeanor showed no trace of childishness. He felt completely like a mature adult; this was his most intuitive feeling.
If Rey saved him and was now preparing to save his daughter out of empathy as a fellow father, then there was no need for Rey to reveal his true identity. Since he did, Willy hoped to know Rey's purpose.
"You have a choice!"
Knowing what Dr. Willy meant, Rey took a deep breath, seemingly making a decision, and said.
"A choice?"
"Yes. I will save your daughter; you can rest assured about that. It has nothing to do with what you can do for me.
"You can choose to forget everything about tonight. At some point, your daughter will recover, and you will resume your previous life. Of course, you can also choose to accept everything you saw tonight and step into the dangerous world of magic."
Rey didn't demand repayment for his kindness. He wanted the other party to choose willingly. If Willy chose to forget, Rey would find a way to erase his memory of tonight and then secretly cure his daughter.
No coercion—that was Rey's bottom line.
After all, a sudden change in life isn't something every ordinary person can accept with joy.
