From Hogwarts to Strixhaven

October came in the blink of an eye, and the damp cold penetrated every corner of the castle. The teachers and students of Hogwarts quietly added more clothes for themselves.

But even so, it could not stop the sudden cold. Mrs. Pomfrey, the head nurse of the school hospital, was overwhelmed and had to ask for the help of Snape, the professor of potions, hoping that he could provide a batch of refreshing potions as a special medicine for colds.

And Professor Snape has always been the busiest person in the college. He has to clean up the mess made by clumsy students in class, and often faces conflicts and riots between the two colleges after class (even if they are not named, everyone knows which two colleges they are), and from time to time he has to put Harry Potter in confinement, not to mention his own research.

Recently, Snape has a paper to submit to the Extraordinary Apothecary Association, which is about the improvement of wolfsbane potion. Not long ago, Damocles Belby published a paper on wolfsbane potion in the journal "Extraordinary Potions" under the Extraordinary Apothecary Association. As a potion master, Snape could see at a glance that there was still room for improvement. The raw materials of wolfsbane potion were too expensive, and the poor werewolves could not afford it.

If this problem could be solved, I believe the Ministry of Magic would not be stingy with a Merlin Medal, and as a Slytherin who pursues honor, Snape has every reason to pursue it.

"You really made me look for you, Mr. Doom." When Ivy, who was sitting in the crup kennel and using the wizard's hand to clean the hairy crabs on the puppies, saw his own dean, he was stunned.

This semester, Ivy had clearly obtained Dumbledore's permission to not attend any courses and decide on his own study plan. Except for the career guidance for the next semester, he should not have any intersection with Snape.

"What can I do for you, Professor Snape?" Ivy closed the book and asked politely, but did not get up from the chair, and even the wizard's hand that was fiddling with the crup puppies in the air did not stop moving.

"In short, I need your 'hand'." Snape glanced at the wizard's hand that was catching the hairy crab on the crup and said expressionlessly.

"Oh, so that's it, they are all there, please help yourself." Ivy spread his hands, indicating that Snape could take them by himself.

"Since last Christmas, Lucius has been writing to me, praising you generously, Mr. Doom. 'Can lead Slytherin to another glory', is that what he said?" Even though he was praising Ivy, Snape's face was still expressionless, "If you remember, I am the dean of Slytherin..."

"I have to deal with O.W.L.s, professor." Ivy interrupted Snape's flattery and raised the book in his hand, which was "The Most Toxic Magic" borrowed from the restricted area. "I'm busy with schoolwork!"

Ivy was surprised to see Snape's mouth curled up: "Busy studying black magic? I can teach you a few tricks, Mr. Doom."

He took out his wand, pointed at the dogtail flower on the open space, and said in a voice that was almost whispered: "God's Edge Without Shadow."

Without any sound and light effects, the dogtail flower was abruptly broken into two sections.

Ivy narrowed his eyes. He knew that this was Snape's specialty. It was a silent black magic cutting spell that could only be cured with a specific counter-spell. It was an excellent black magic. Snape, who invented it, was still studying at Hogwarts.

"Make a refreshing potion for Madam Pomfrey, the head nurse. The raw materials are in the potion classroom. I allow you to use it after dinner." Snape looked at the expression on Ivy's face with an inquiring look. "When everything is over, I will tell you its counter-spell."

After saying this, Snape left in a hurry without waiting for Ivy's consent.

He crossed the corridor of the castle like a bat with its wings spread, said this year's password "Noble Rot Wine" in front of the gargoyles, and then broke into the principal's office on the eighth floor.

"Severus?" Dumbledore had just poured a bottle of memory like mist into the Pensieve when he saw Snape with a solemn face. "Whatever you want to say, please sit down."

Snape moved away from the chair that he had run to under his buttocks: "I think you must know that Ivy Doom is studying the dark arts. And this is not the first time I have discovered this. I don't know who gave him the restricted books section note."

Dumbledore slowly left the Pensieve and picked up the half-moon glasses he had placed on the desk: "I gave it to him. I believe Ivy has his own sense of propriety."

"Oh? Believe in a Hogwarts transfer student who claims to be from more than a hundred years ago but has never been found?" Snape asked back, "Did he infuse you with Love potion?"

"Of course not, Severus." Dumbledore smiled, "Ivy is the most talented wizard I have ever seen..."

"I must remind you, Dumbledore." Snape interrupted him, "The last person you commented on was Voldemort."

"Ivy is different from Voldemort," Dumbledore took out a bottle of golden noble rot wine. He and Ivy received a lot of it when they left Nicolas Flamel last time. "He knows what he is doing."

"..."Snape was silent for a while, and continued, "It seems that something happened between you that I don't know. Perhaps you should know that Lucius Malfoy has some too close contacts with him."

"You mean the breeding and reproduction base for magical animals?" Dumbledore raised his eyebrows, "When did you find out that Ivy kept dragons in the castle?"

No mistake!

"He still keeps dragons in the castle?" Snape raised his voice, almost roaring, which was not common in the potion professor who always spoke in an aria.

"Oh - so you haven't discovered this yet... I allowed you to raise dragons, and perhaps the Ministry of Magic's permission will be delivered by owl soon." Dumbledore said briskly, "Then you can use fresh dragon blood."

"Ivy is a talented wizard, perhaps too talented." Dumbledore sighed, "In some ways, he is stronger than me and Voldemort. But don't worry, we are united in destroying Voldemort."

...

Snape was not happy with the conversation with Dumbledore, and when he saw Harry walking into the castle with muddy clothes, he did not do anything extreme, but simply deducted five points from him and asked him to go to Filch to collect the reward.
