I've already become a Hogwarts professor, and the system only just appeared.

This water is no ordinary water; it was all collected by Snape a few days ago, little by little, using this silver teaspoon when the dew rose at night. In China, it would be called rootless water.

The rootless water entered the bottle, and Snape began to stir the potion in a certain rhythm with a teaspoon. There was no stirring step in the Transfiguration books, but Su Yu believed in Snape's professional skills as a potion master, as well as his character.

Chapter 98 Animagus Metamorphosis

As Snape stirred, the potion in the crystal bottle slowly became crystal clear, just like a bottle of grape-flavored jelly.

Finally, Snape took out the hawkmoth pupa and threw it into the potion. The addition of the hawkmoth pupa was like pouring hot oil into a calm pond; the potion in the bottle instantly boiled and began to bubble.

Snape's face was serious as he continued to stir with a silver teaspoon, but this time the direction and trajectory of his stirring were slightly different from before.

With Snape stirring, the scorpion pupa quickly dissolved in the potion, which changed from a light purple to a deep purple.

Mission accomplished, Snape put the potion in a wooden box and said, "Alright, from now on, until the next storm, this potion must not be exposed to sunlight. As for what to do after that, I think you know better than I do."

"Thanks, but actually you don't need to wait that long. There's a storm in eastern France tomorrow, and I'm planning to head straight there," Su Yu said gratefully.

Upon hearing Su Yu's words, Snape was taken aback. He had never practiced Animagus transformation, but he was clear about the general process. He really hadn't expected that it was possible to cheat like this.

However, Snape was still somewhat worried and said, "You'd better ask Professor McGonagall to see if this method is feasible."

"But if you ask me, you really don't need to learn Animagus magic, which is a thankless and difficult skill. It's too dangerous; if you're not careful, you won't be able to turn back into a human."

"Even if you succeed, it won't have much of an impact on your magical abilities. Dumbledore can't transform into Animagus, but that doesn't change the fact that he is still the greatest white wizard of our time."

To be fair, Snape made a lot of sense. Animagus transformations can only turn wizards into ordinary animals, and they cannot use magic after transformation, so they are not very useful in combat.

But Animagus is so cool! Professor McGonagall's feat of turning a cat into a human at the start of the semester attracted countless young wizards, and Su Yu had long yearned for it.

Moreover, the true role of the Animagus is actually to conceal and assist. For example, Rita Skeeter's beetle, Sirius Black's black dog, and Peter Pettigrew's rat all greatly helped them to hide.

Therefore, Su Yu was very much looking forward to his Animagus transformation. The next day was the weekend, and Su Yu arrived at Professor McGonagall's office early in the morning:

“Professor, do you have time today? I want to begin my Animagus transformation.”

A glint of surprise appeared in Professor McGonagall's eyes. Su Yu had been her student for over a year, and she had witnessed his progress.

Professor McGonagall provided meticulous guidance to Su Yu's Animagus transformation, so she was equally looking forward to it.

However, Professor McGonagall quickly realized something was wrong. She looked up at the window and said, "But there's no thunderstorm today."

Su Yu blinked: "Just because there are no thunderstorms in Britain doesn't mean there aren't in other places. There's currently a storm in the sea area bordering eastern France and Germany. If you have time, we can go there."

Unlike Snape, Professor McGonagall truly understood Transfiguration. She knew that the reason for choosing a thunderstorm was that during a thunderstorm, the lightning in nature would activate the natural energy in the air that was originally stagnant.

Some of this natural energy is transformed into magic, which floats in the air. This magic, derived from natural energy, is the key to performing Animagus transformations.

Therefore, although Su Yu's method seemed like cheating, it didn't actually matter. So she nodded and said, "In that case, let's go!"

So the two of them arrived outside Hogwarts Castle, got into Su Yu's magical Bentley, and soared into the sky, speeding off in the southeast direction.

Looking at the luxurious interior of the car, Professor McGonagall couldn't help but sigh, "It's really impressive. You young people these days always come up with something new and interesting. We old folks just can't understand it anymore."

"Haha, how could that be? Professor McGonagall, you're quite skilled at using the magic phone! I often check your Moments!" Su Yu joked with a smile.

Professor McGonagall was clearly in a good mood, saying, "Magic is meant to make life more convenient. I'm not like some old fogies who cling to outdated ideas and refuse to move forward."

"Professor, you're not talking about Headmaster Dumbledore, are you? Be careful, or I'll snitch!" Su Yu said with a grin.

Professor McGonagall shook her head: "Professor Dumbledore can be quite old-fashioned at times, but he is open to new things. The real obstacles to the development of magic are the pure-bloods who hold enormous profits, and the bigwigs of the Ministry of Magic."

Su Yu didn't know if Professor McGonagall's sudden remark to him had any deeper meaning, but since she brought it up, Su Yu went along with it:

"You don't need to worry about that. I've joined forces with Arthur Weasley, and we're working on ways to promote the modernization of magical items. I believe it won't be long before products like magical cars are available for sale in the British magical community."

Hearing Su Yu's words, Professor McGonagall didn't seem surprised at all. She rolled down the car window, let the wind blow on her, and chatted with Su Yu casually.

Before long, the clouds in the sky began to thicken, and lightning gradually streaked across the distant clouds, making a low rumble.

Su Yu immediately descended, rushed into the storm, and finally landed on a small island, where he took out the potion that Snape had prepared for him.

The two stood in the downpour. The rain stopped less than half a meter away from them and then slid down around them. From a distance, it looked as if they were surrounded by an invisible eggshell.

"Are you ready?" Professor McGonagall asked, her voice still clearly audible amidst the cacophony of the downpour.

"Ready!" Su Yu nodded.

“Very good. Drink the potion, point your wand at your heart, and chant the spell ‘Amador, Animus, Animador, Animagus.’” Professor McGonagall continued earnestly and solemnly:

"Remember, the first transformation might hurt a little, but you must have full confidence in yourself and firmly believe that you can succeed. You cannot have a single doubt!"

"Besides that, guard your inner self and don't let your wild instincts influence you. Okay, let's begin!"

Professor McGonagall had said this before, but Su Yu listened attentively and kept it in mind. Magic is essentially about making your wishes come true; it's the power of belief. As long as you believe, you can succeed.

Taking a deep breath, Su Yu gulped down the bottle of medicine. It tasted similar to jelly, slightly astringent, and with a faint sweetness. It was hard to imagine that this stuff was made from saliva.

Chapter 99 An Unsettled Weekend (Part 1)

As soon as the medicine entered his mouth, Su Yu felt a surge of heat rise from his abdomen, rushing upwards towards his heart. Immediately afterward, his heart convulsed violently, causing him great pain.

Outwardly, Su Yu stumbled, almost losing his balance, and the egg-shaped rain curtain around him became disordered.

Su Yu knelt on one knee, pointed his wand at his heart, raised his head, and shouted loudly, "Amado, Animo, Animado, Animagus!"

After the incantation was finished, the tip of the wand emitted a large amount of silver-blue light, which passed through Su Yu's heart and then formed a cocoon around his body.

"Ah!" Su Yu roared like a wild beast. He felt that the heat seemed to have melted his heart, and then it surged through his body with his blood, melting his bones, flesh and skin.

Gradually, Su Yu's sense of touch failed. Relying on his mental power, he felt as if his body had turned into a ball of flesh. Suddenly, the center of the ball of flesh throbbed—it was a new heart.

Then his body began to reshape itself, and it looked like the shape of a bird. So, was his Animagus form a bird?

After an unknown amount of time, the blue cocoon of light surrounding Su Yu finally shattered, and a jet-black raven flew out from within. At that moment, Su Yu experienced the joy of flying on his own.

He flapped his wings and weaved through the thunderstorm, sometimes rapidly ascending and sometimes plunging at high speed, performing all sorts of fancy maneuvers in the air, seemingly enjoying himself immensely.

No, no, this isn't right! While flying, Su Yu suddenly snapped out of his daze, remembering Professor McGonagall's words of advice before the transformation:

"In addition, guard your inner self and don't let the wildness of animals influence you!"

Su Yu suppressed his instinctive desires, forcibly controlling his body to descend until he landed on Professor McGonagall's shoulder, before beginning to examine his soul.

At this moment, he discovered that there was a newborn soul inside his body. It was very weak and did not have much intelligence, but it was genuinely influencing Su Yu's thoughts.

"It's you!" Su Yu's eyes lit up. Controlling his soul, he devoured the newly born soul in one bite. How to put it? It was crunchy and tasted delicious.

This is a kind of pleasure and enhancement from the soul level. In terms of the character panel, it is like having an extra buff: Soul Enhancement: Your soul is exceptionally powerful, and your mental strength increases by 10%.

Su Yu hadn't expected that the Animagus transformation would bring him such a boost. Although the enhancement of mental power couldn't directly increase the maximum value of magic power, it could improve the wizard's endurance.

Perhaps this is the greatest enhancement that Animagus transformation brings to wizards. Su Yu jumped off Professor McGonagall's shoulder and transformed back into human form.

"Professor, I did it!" Su Yu said excitedly.

Professor McGonagall smiled and nodded, "Very good, I knew you'd be fine. By the way, according to British wizarding law, after completing Animagus, you need to register with the Ministry of Magic."

"Professor, as far as I know, many Animagus don't report this!" Su Yu naturally didn't want to report it; he was still thinking of using it to trick people.

Professor McGonagall smiled and shook her head, saying, "I'm not saying this to ask you to report it to me. I just want to tell you that if you don't want to report it to me, then try not to use it in front of people you don't trust."

"Hehe, I understand!" Su Yu gave Professor McGonagall an OK sign. He really did understand, because he had a weakness of the Animagus that he held in his hand.

After completing their transformation, the two returned to Hogwarts by car. The school was still sunny and warm at the time. Although the weather was a bit chilly at the end of October, it was still quite comfortable.

Snape had been somewhat distracted all day. He'd already made several mistakes while experimenting with potions in his underground office. Looking out the skylight, he muttered to himself:

"I wonder if Su Yu's Animagus transformation was successful. I hope he doesn't really turn into an animal and not be able to recover. If that's the case, I'll keep him as a pet."

Then Snape chuckled to himself, wondering how he could have such a thought. With Professor McGonagall watching over him, Su Yu couldn't possibly get into trouble, absolutely not.

"Caw caw!" Just then, a raven landed on the railing of the office skylight and cawed loudly.

Snape was annoyed by the sound, so he picked up a scrap of paper and threw it at the raven. He added some magic to the throw, making it very fast, but he controlled the force well enough not to kill the raven.

To Snape's surprise, the raven deftly dodged his attack with a sideways leap, and once again let out its unpleasant cawing: "Caw! Caw!"

Snape immediately became suspicious and curiously examined the raven, which was none other than Su Yu. He was still disguising himself, preening his feathers with his beak like an ordinary raven.

In fact, Su Yu had always had some questions about Animagus transformation, such as why the clothes would change along with the transformation.

For example, after the transformation, are the exposed anus and penis really one's real anus and penis?

Having learned how to transform into an Animagus, Su Yu tested it himself and could only say that the transformed body was no longer his original body.

His original body must have been stored in a space within the animal form; the transformation was merely a change of form.

"Raven, come here!" Just as Su Yu was distracted, Snape suddenly raised his wand and cast a Summoning Charm.

Then Su Yu felt his body being bound by some kind of force, followed by a pulling force that dragged him through the crack in the skylight into Snape's office.

Damn it, he'd been discovered. After entering the office, Su Yu immediately reverted to human form and broke free from Snape's control.

"It really was you! I can't believe you actually got lucky and succeeded. But you'd better not transform in front of me again, or I'll lock you in a cage and make you test my potions!"

Snape's voice sounded somewhat pleased, though it was unclear whether he was happy because Su Yu had successfully transformed or because he was thinking about Su Yu helping him test the medicine.

Su Yu wasn't angry. He said with a grin, "Hehe, I arrived just now when you were talking to yourself. I heard everything you said. Don't deny it, you still care about me."

"No, you misheard!" Snape's expression changed instantly, and he emphasized again, "Remember, don't use your Animagus form to attract the attention of wizards. It's a very dangerous thing."

Chapter 100 An Unsettled Weekend (Part 2)

Rewind a bit. When Su Yu and Professor McGonagall left Hogwarts, Cho Chang also woke up exceptionally early today. As a third-year wizard, she was now eligible to travel to Hogsmeade Village on weekends.

Upon arriving at Hogsmeade Village, Zhang Qiu separated from the main group, wandered around the village for a long time, put on a large cloak, and then returned to the entrance of Feiyu Mobile Phone Shop.

Zhang Qiu glanced at the mobile phone store with a complicated expression, but she wasn't there to buy a phone. Her real target was the Three Brooms Bar across the street.

Without greeting the front desk, Zhang Qiu went straight to room 210 on the second floor. She knocked on the door rhythmically, and after a short while, the door opened.

Zhang Qiu stood at the door, hesitated for a while, and finally gritted her teeth and went inside.

The room was quite large, with a double bed and a sofa. At that moment, a middle-aged man sat elegantly on the sofa, holding a cup of tea. He had a terrifying scar on one eye; he was none other than Count Dracula, the vampire.

Upon seeing Dracula, Zhang Qiu trembled slightly and stopped three meters away from him, bowing his head and remaining silent.

"Has the secret room been opened?" Dracula put down his teacup and asked softly.

“I…I opened it once…” Zhang Qiu said tremblingly.

"What's inside?" Dracula continued to ask.
