Hogwarts: I am the White Demon King

On the Hogwarts Express.

Harry, Ron, and Hermione, who hadn't seen each other for a vacation, gathered in a compartment, sharing their summer experiences.

Ron glanced in the direction of the front of the train and said to Hermione and Harry, "Did you notice that another carriage has been added in front of the prefects' carriage? It should be the professors' carriage."

"I arrived a little earlier and saw Remus Lupin go into that carriage. When he arrived, he caused a sensation on the platform. Many students and parents were asking him for autographs."

"You should call him Professor Lupin, Ron," Hermione said. "Now it seems certain that he's the new Defense Against the Dark Arts professor."

"What I mean is," Ron said with a mysterious look, "Professor Lupin was doing so well as a TV star, why would he want to become a professor?"

"And... he's a werewolf. What was Headmaster Dumbledore thinking, letting him become a professor? Isn't he afraid of the students' parents making a fuss?"

"Ron," Hermione rolled her eyes at Ron and said impatiently, "If you read the news more often, you'd know that the Wolfsbane Potion has been invented for a whole year now."

"As long as they take the Wolfsbane Potion on time, werewolves can work normally. I think the headmaster considered this when he let him teach Defense Against the Dark Arts."

"Besides, we met Professor Lupin last year on Harry's birthday. He seems like a very gentle person."

"Of course I know Professor Lupin is gentle," Ron scratched his head. "I just think that the wizarding world has a lot of prejudice against werewolves, and many students' parents will complain about him teaching at Hogwarts."

"He finally built up a good reputation through TV dramas. If students' parents make trouble, his reputation will be ruined."

"No matter how you look at it, coming to Hogwarts to teach is not a very good choice for him."

Harry shook his head gently: "On my birthday this year, Professor Lupin told me that he had agreed to Headmaster Dumbledore's request last year, so he specifically turned down all filming plans."

"He actually sacrificed a lot, after all, filming TV shows makes more money than being a professor."

"By the way, Harry," Hermione said with a curious face, "Did you have a happy birthday this year? What kind of special training did you do during the summer vacation?"

"My birthday was pretty good, thank you for the gifts. As for the special training, Professor Snape was teaching me how to brew the Wit-Sharpening Potion at the beginning of the vacation."

Before he finished speaking, Hermione screamed: "Wit-Sharpening Potion?!"

"I saw in a book that it's a very advanced potion that can improve a person's memory, but the brewing process is very difficult."

"It is said that only potion masters can brew this potion."

"You've actually started learning the Wit-Sharpening Potion, oh my gosh, I'm so far behind you in potions."

"I haven't succeeded perfectly yet," Harry waved his hands repeatedly, looking modest, "However, my potion-making skills have improved a lot."

"I can teach you the skills I've learned."

"The Wit-Sharpening Potion brewed by Professor Snape is very perfect. After I drank a portion of the potion, my memory did improve a lot."

"Improve memory?" Ron's curiosity exploded. He looked at Harry, his face full of jealousy.

"Seriously, Harry, I've always suspected that you and Professor Snape have some special relationship, otherwise why would he be so good to you?"

That's a potion that can improve memory!

If possible, he would also like to have a portion.

"Tell me quickly, what does it feel like after your memory is improved?"

"It feels like I can remember things much faster. I can completely memorize those complex potion recipes after reading them twice."

"Of course, this potion also has some side effects." Harry's face gradually darkened.

The rain outside the window suddenly became heavier, and the train window was covered with rain, becoming gray, just like Harry's mood.

"Those things I don't want to remember will also appear in my mind from time to time."

"For example, Sirius Black's wanted poster."

"Sirius?" Hermione said with a worried face, "Harry, you said in the letter that Sirius is coming for you, what exactly is going on? Can you tell me in detail?"

"He betrayed my parents, defected to the Dark Lord, and now he's out to kill me to win favor with his master."

Hermione's face instantly became serious, her brows furrowed: "Harry, this is no small matter. You must be very careful. If you ask me, before he's caught, you'd better not even go to Hogsmeade."

"I'm not afraid of him, I wish he would come to me," Harry said hatefully, "Professor Snape taught me a particularly powerful spell, and I've been practicing it desperately this summer to catch him."

Ron showed a confident smile and patted Harry on the shoulder: "I support you, I believe you can definitely defeat him."

Hermione quickly interrupted Ron's optimism, her voice filled with sternness: "Ron, don't be silly! Sirius Black is not an enemy that we underage wizards can deal with."

"Even the Muggle world is reporting his jailbreak, which is enough to show how dangerous he is."

"It's definitely not letting Harry fight alone," Ron said confidently, "The two of us will help him. If we encounter Sirius Black, the three of us will go together, and maybe we can directly knock Sirius Black down."

"You know, Harry has been receiving special training from Professor Swann. His strength is not comparable to ordinary students. Plus the two of us assisting from the side, Sirius Black will definitely not get any advantage."

"When the time comes, we'll catch him and exchange him for a reward from the Ministry of Magic, wouldn't that be perfect?"

Hermione glared at Ron dissatisfiedly, as if glaring at an idiot.

Ron didn't seem to notice Hermione's gaze, and raised Harry's arm to Hermione and said, "Harry is fully equipped, look at his sleeves, even the buttons on them are protective gear."

"In addition, Harry also has many different alchemical protective gears, such as a vest made of basilisk skin that can resist most spells."

"I dare say, with this protective gear alone, even if he stood there and let Sirius Black hit him, he would have to hit him for a long time."

"There's an old saying in the wizarding world, Galleons are combat power."

Just as they were arguing, the train began to slow down, the sound of the wheels gradually disappeared, and the wind and rain hit the windows, making a disturbing noise.

Suddenly, the train stopped abruptly, and the sound of luggage falling from the racks came from a distance.

Immediately afterwards, all the lights went out, and the carriage was plunged into complete darkness.

Accompanied by a black shadow flying past the window, the rain on the window began to freeze into ice, and the temperature in the carriage dropped sharply.

"There's a problem, everyone be careful!" Harry felt a palpitation, he vigilantly pulled out his wand and dispelled the darkness in the carriage with the Lumos charm.

"Take out your wands, I'll go out and see what happened."

At this moment, the sliding door of the carriage slowly opened, and a figure completely shrouded in a black cloak stood outside the door.

Seeing Harry standing there, the figure began to inhale towards him.

In an instant, a bone-chilling chill struck, the chill seemed to penetrate his skin and freeze his heart.

Enemy!

Must fight back!

Long-term training made Harry subconsciously raise his wand.

He did not hesitate to use the most powerful spell he had learned so far.

"Sectumsempra!"
