From Hogwarts to Strixhaven.

Chapter 219 Full Moon Night
The weather in the British Isles is never very good, which is why the British always talk about the weather when they greet each other.

Even on an early spring night, the sky was filled with thick clouds, completely blocking the light of the full moon.

However, even without the moonlight, the madness brought by the full moon still permeated Lupin who was hiding in the Room of Requirement.

His body was shaking, like a man who had been running shirtless in the snow for a long time.

"Is the wolfsbane potion really effective?" Sirius couldn't help but ask. He looked at Lupin lying on the ground worriedly. "Could Snape have secretly tampered with it?"

Lupin twitched and gave an ugly smile: "If he really did something, it wouldn't happen at night..."

This is a new room that Ivy built in the Room of Requirement. The floor is made of a whole piece of smooth marble, and now there is a particularly complex magic circle carved on it with dragon blood.

That was the flesh and blood magic that Ivy had just learned from the Restricted Area not long ago, combined with DND spell theory. He broke down the wizard's spell into several complex runes to slow down the entire process of the flesh and blood magic taking effect.

He hoped to use this method to observe how the lycanthropy curse affected the wizard's flesh and blood, and why it was entangled with the wizard's own magic.

Because the effect of the magic circle is only to slow down Lupin's transformation process, it will not cause him too much harm. At most, the pain he feels during the transformation will be prolonged.

The reason for using dragon blood is that it is a magical material commonly used by wizards and has good magical conductivity. Although it cannot be reused, Ivy can still afford it once a month.

After finishing the last stroke of the magic circle, Ivy stood up, clapped his hands, and said, "That's enough, Professor Lupin, you don't have to suppress your urge to transform anymore."

As soon as Ivy finished speaking, Lupin groaned, curled up and fell to the ground.

"What's going on?" Sirius was very nervous. "When we were at Hogwarts before, we never saw him like this. He always transformed in an instant!"

As if in response to Sirius's words, Lupin began to howl in pain.

The first thing to change was his head. The human upper and lower jaw began to lengthen, the nasal bone extended forward and soon merged with the snout. His eyes turned an unpleasant yellow, and his ears gradually began to move upwards, changing from human round ears to canine pointed ears.

Ivy didn't blink, and didn't have time to answer Sirius's question. He focused on Lupin, who had a bald wolf head. Lupin looked particularly weird and scary at this time, because his wolf head was obviously not something a normal human should have, but his body still maintained its original appearance. The overall image fell perfectly into the category of the uncanny valley, which only made people feel creepy and terrified.

Fortunately, this situation did not last long. After the head was transformed, Lupin took a long breath, and then a lot of black and gray hair emerged from all over his body, covering his pale skin and looking more like a wolf. Ivy also noticed that his canine teeth protruded from his mouth, adding a more ferocious look to his overall appearance.

Then, it was the other bones in Lupin's body that changed. With a crackling sound, his shoulders swelled up, his fingers curled into claws, and his shiny black nails were like sharp steel knives...

As for the other parts, Ivy couldn't see them yet because they were covered by the clothes Lupin was wearing.

"Vanish without a trace!" Ivy took out her wand and thrust it forward. Lupin's robe suddenly disappeared, leaving only a pair of washed-out shorts.

Ivy noticed that Lupin's ribs were getting thicker and the curvature of his spine had changed dramatically. If the same changes happened to an ordinary human, it would at least be cervical spondylosis and lumbar disc herniation.

The impact of lycanthropy continued to spread downwards, and Lupin's bones were undergoing tremendous changes. Ivy watched him grow several inches taller. In addition to the black and gray hair, Lupin's leg bones were also stretched a bit, but the biggest change was in his feet. The human muscle tissue at the heel began to become closer to the bones, and it looked like it had become another joint opposite to the knee joint, while the part that originally belonged to the forefoot became much longer and wider, and the five toes were tightly shrunk together, and even grew fleshy pads.

Until this point, Lupin's changes under the influence of the full moon were completely complete.

As a werewolf with an inverted joint structure, if Lupin stood up, it would be like a human walking on tiptoe, not to mention that the previous drastic change made his skeleton grow several inches. This is why the werewolf looks particularly scary and terrifying after transformation. The oppressive feeling brought by the height and body size can easily arouse people's fear.

"Remus?" Sirius asked softly, "Are you okay?"

Lupin, who had completed his transformation into a werewolf, looked even weaker. He failed to stand up from the ground after several attempts. He couldn't even control his mouth flexibly and couldn't even answer Sirius' questions.

Ivy conjured up a huge sofa chair and placed it next to Lupin, then helped him sit on it. He then took two steps forward and asked, "Is your self-awareness still clear, Professor Lupin?"

The werewolf grunted a few times, but finally nodded in compromise.

"It seems that the wolfsbane potion is indeed effective." Ivy speculated, "It allows the beast in your body to return to your true self. Now the dominant part is still your rational part..."

"Very good, I can see it clearly now." Ivy nodded, "But in order to verify my guess, I still need your help to do some tests."

"Let Remus rest for a while..." Sirius suggested, "He is even weaker than I am."

"Okay." Ivy nodded in agreement with the suggestion, then snapped his fingers. Maomao, wearing a white chef hat and a clean white chef uniform, appeared beside him. "Come and help us grill the meat, Maomao."

"Yes, sir!" Chef Bobby stepped on his heels and saluted Ivy, then disappeared on the spot with a crackling sound.

Then Ivy began to arrange the venue. He pointed his wand downwards, and the ground suddenly bulged upwards to form an elongated, widened and thickened stone table. He then conjured up two chairs for himself and Sirius, and all the preparations for the barbecue venue were completed.

When Chef Bobby appeared again, he was followed by several other house-elves, holding tableware, ovens, charcoal basins, seasoning boxes and freshly processed meat.

Lupin's bright red tongue popped out of his mouth and he licked his fangs unconsciously.

Ivy happened to see this scene: "Even with the help of wolfsbane potion, some of the werewolf's physiological instincts are still manifested in you. This is something worth studying."

Lupin's wolf face showed a human-like helpless expression, and Sirius was completely relieved and went to watch the house-elves grilling. "Before the barbecue is officially served, let me ask you some questions." Ivy handed over a wand that Lupin had given him before he transformed. "Try this. I'm curious if lycanthropy affects your ability to cast spells as a wizard during a full moon."

Lupin took the wand and grunted again.

"Can't cast a spell?" Ivy understood what he meant. "Then try a silent spell, a simple silent levitation spell?"

The furry wolf head nodded and waved his wand at the plate of food that the house-elf had brought up.

But nothing happened.

Lupin was also surprised by this result. After all, he had no self-awareness when he turned into a werewolf before, so there was no question of casting spells. But after drinking the wolfsbane potion, he could maintain his sanity in the werewolf state, so casting spells should be a piece of cake for him.

But the actual situation is completely different from what we imagined.

"Did lycanthropy cause you to lose your ability to cast spells?" Ivy pondered for a moment and continued, "It's still too early to draw a conclusion. I should find a way to help you regain your ability to speak. How should I do it?"

Finally, Ivy decided to use Transfiguration. He pointed his silver lime wand at Lupin's throat and said, "Open your mouth, Professor Lupin. I will change your glottis into the shape of a human. As for the coordination of your mouth and tongue, you may need to explore it yourself."

The werewolf stared at him with its yellow eyes for a while, and finally opened its mouth cooperatively, revealing a mouthful of fangs and a scarlet tongue.

"Very good--" Ivy released another 0-ring trick, Light Dance. A grain-sized light dot floated into Lupin's throat, providing illumination for Ivy. "Hold on--"

"Transform quickly!"

The light from the wand hit Lupin's throat, and he sneezed violently, blowing the ball of light created by Ivy far away, and then he started coughing violently.

"It's bad, Jane..." the werewolf muttered. Ivy's magic did work. Although Lupin's canine teeth were a little leaky, at least he could speak, right?

"Very good, there will be no communication barrier now." Ivy sat back with satisfaction. "Let's try again, the levitation spell."

"Yuguatimureweiaosa!" Lupin grinned and tried to move his tongue.

"Wingardium's tears taste like that!" Lupin stuck out his tongue and stroked it with his paw.

"Wingardium Leviosa!" The standard spell was accompanied by a standard wand-waving gesture, but just like the previous silent spell, the plates on the table did not move at all.

"..." Lupin was silent for a moment, then stared at his wand for a long time before saying, "I can feel that my magic power has not disappeared... but has turned into a form that is more difficult to command... just like... water is frozen into ice."

"Another great discovery." Ivy nodded. "Can you describe how you felt as you gradually transformed into a werewolf?"

The werewolf sitting opposite Ivy shuddered, as if recalling an unbearable experience: "I have never felt such pain, like tearing your skin off, crushing your bones, and then gluing them together..."

"Besides these?" Ivy continued, "Besides these physical sensations, what do your magical senses feel?"

"Magical senses?" Lupin's wolf face showed obvious confusion. Some saliva dripped from the hair around his mouth onto the table. He himself seemed unaware. "I don't quite understand..."

"We all know that lycanthropy is a change that occurs under the influence of the full moon and magic," Ivy tried to describe. "So how do your senses, who are responsible for chanting spells and casting spells, feel about this process?"

Lupin seemed to understand: "Some things woke up... others fell asleep... It was a bit like a tug-of-war, and I was the rope in the middle... Both sides were pulling at me, trying to tear me apart..."

"Is the food ready, Master Doom?" Seeing Ivy lost in thought, Maomao came over with a tray. Ivy looked back and saw Sirius had already started eating.

Ivy then realized that the room was full of the aroma of barbecue. No wonder Lupin was drooling just now. Although he himself did not seem to react to it, his body was very honest.

"Of course, Maomao, serve the food!" As soon as Ivy finished speaking, the stone table was immediately filled with all kinds of grilled meat, including beef roasted over an open fire, lamb chops grilled on a rock slab, and a variety of tempting and delicious vegetables and mushrooms.

Lupin's stomach let out a loud scream, which scared him.

"Let's eat and talk at the same time." Ivy put a large piece of beef ribs on his plate. After cutting it with a knife, he could see not only the steaming juice but also the light pink muscle fibers.

Lupin tried the knife and fork clumsily with his claws, and finally decided to go for it. The sharp fangs only tore lightly and pulled off a large piece of meat from the huge beef rib. In just two or three bites, the whole piece of beef rib disappeared in his mouth. Lupin hesitated for a moment, but finally couldn't resist the instinct of his body and ate the smooth beef rib as if it were a chocolate bar.

"From your previous description, I have a rough guess." Ivy picked up a piece of hot beef and dipped it in Maomao's special sauce. "The lycanthropy curse does not force you to transform, but awakens another consciousness in your body that is dominated by animal instincts. This consciousness itself still comes from you. This is why the wolfsbane potion is effective. It puts the animal in your body to sleep."

"And this beastly power in you is manipulated by the changes in the phases of the moon. So I think as long as I reduce the impact of the moon's tides on you - in other words, or spread this impact from the full moon to other days of the month, you should be able to control the timing of your transformation into a werewolf."

"Wait!" Sirius put down the beef leg bone in his hand, "Aren't we discussing how to cure Remus?"

"No, we are discussing how to make lycanthropy a power of Professor Lupin himself."
