A few days later, Harry, Ron, and Ginny lined up by the kitchen fire to return to Hogwarts.

The staff of the Ministry of Magic's Department of Transportation arranged this one-time Floo network connection to Hogwarts in the kitchen of the Burrow, so that students could return to school quickly and safely.

Harry stepped into the turquoise fire and shouted, "Hogwarts!"

Then, in the high-speed rotation, he vaguely saw some of the wizards' rooms, all of which flashed by before they could see clearly. Then he slowed down, and he found himself stopped in Professor McGonagall's fireplace in a very indecent motion.

When he climbed out of the fireplace, the vice-principal who was working barely raised his head:

"Good evening, Potter, don't get too much dust on the carpet. ”

"I swear I didn't, Professor. Harry hurriedly straightened his glasses and smoothed his hair.

Just as he was about to walk out of Professor McGonagall's office, he stopped in a mysterious way, "Excuse me...... Professor...... Professor Slughorn's injury, I don't know if he has recovered. ”

Professor Minerva-McGonagall put down her quill pen, put on her glasses, and glanced Harry up and down...... After a few moments, she replied slowly, "No...... Horace is still recuperating at St. Mungo, is there any problem?"

"No...... No, no, no...... I mean, which teacher should be in charge of Professor Slughorn's Potions class...... Could it be Professor Snape......" Harry stammered.

"I don't think I know, Potter...... Professor Dumbledore just told me he had the right personnel!" Professor McGonagall replied calmly, "but considering Professor Snape's familiarity with the course, it's highly likely. ”

"Okay...... Thank you, Professor!"

In the fireplace, Ron and Ginny also appeared in a spin...... Harry quickly dusted himself off before walking out of Professor McGonagall's office.

......

The three of them walked together towards the Gryffindor Tower. Harry looked out of the hallway window, the sun had sunk above the horizon, and the snow on the field was deeper than in the Burrow Garden...... In the distance, Hagrid can be seen in front of his hut, feeding several Thestrals.

"What did you just ask Professor McGonagall?" Ron asked quietly.

"Ask who is going to substitute for Potions...... Professor McGonagall told me she didn't know, but it was highly likely that Snape would substitute for ......," Harry replied honestly.

"Okay...... But I think we'll know tomorrow afternoon...... Tomorrow afternoon is the first Potions class of the semester!" Ron replied with a sigh.

Harry couldn't help but feel his heart tighten......

If it's Snape...... If it's Snape......

He must have known that he didn't make those potions out of his own skills...... He might even discover the secrets of the half-blood prince!

After much thought, and as he approached the portrait of the fat lady, Harry Potter decided to turn around and run.

"Harry, where are you going?" Ron and Ginny asked aloud behind them.

"I'm going to the Room of Need, and I'll be right back. ”

Harry had already made up his mind that Snape could not be allowed to discover the prince's secrets no matter what...... Therefore, he would rather hide the "Advanced Potions Making" that belonged to the prince in advance.

......

Run along the corridor on the eighth floor.

On the way, he even knocked down a junior girl who was dressed strangely, and he didn't have time to apologize to her.

A few minutes later, he suddenly stopped in front of the tapestry where the trolls danced, closed his eyes and began pacing back and forth.

I need a place for me to hide my things...... I need a place for me to hide my things...... I need a place for me to hide my things......

He walked back and forth three times in front of the empty wall, and when he opened his eyes, he finally saw the door of the Room of Requirement...... Harry pulled it open and rushed inside, slamming the door shut.

Harry was somewhat surprised to find that he was now standing in a room the size of a cathedral.

There were thousands of books, undoubtedly forbidden, scribbled, or stolen, winged slingshots and wolf-tooth flying saucers, several of which were still limp hovering over mountains of forbidden objects, some broken bottles containing solidified potions, hats, jewels, cloaks, and what looked like dragon eggshells, a few gagged bottles still glowing with evil light, and even a few rusty swords and a bloodstained axe......

Harry hurried into an "alley" in the middle of the treasure pile, turned to the right, passed a troll specimen, ran a short distance, turned left next to the cracked vanishing cabinet (the same one Christopher Patrick had disappeared in last year), and finally stopped in front of a large cabinet with a blistering surface that looked like it had been splashed with strong acid.

Opening the cupboard, Harry took out the copy of Advanced Potions Making, which belonged to the half-blood prince, stuffed it in, and then closed the cabinet again.

Just as Harry was about to clap his hands and leave, he noticed another thing fall to the ground.

It's a book with a yellowed cover—

"Wait, how did I put it in my bag......" Harry was stunned for a moment, and his thoughts went back to a few days ago.

That day in the basement of the Burrow, when he opened the gift to Mr. Gideon-Prewit...... He was a little surprised to find that it was actually a book—

A copy of The Magic of Quidditch Ball, published in 1978.

As a Quidditch enthusiast, coupled with the monotony of life in the basement of the Burrow, Harry flipped the book several times while lying in bed.

Unexpectedly, just like the prince's "Advanced Potions Making", the pages of this "Magical Quidditch Ball" are also densely packed with notes...... It was evident that the owner of the book was once a very good Seeker, and some of his Quidditch ideas even Harry felt very beneficial after reading them.

Originally, Harry thought he had left the book in the Burrow, but he didn't expect to put it in his bag.

"Do you want to ...... Leave it here too?" Harry whispered to himself.

He opened the large, blistering cabinet and placed the Magical Quidditch Ball on top of the previous Advanced Potions Making.

At that moment, Harry suddenly felt a little hot with the book in his hand.

So, Harry quickly self-denied his previous decision.

He put the Amazing Quidditch Ball back in his bag.

"I'll be able to take a look when I'm fine!" Harry thought to himself.

......

Out of this "alley".

As I passed by the broken vanishing cabinet, a pale face suddenly appeared in front of me, and I didn't know what to do there—

Harry Potter was almost startled.

The other party also seemed to be taken aback.

"Potter?"

"Malfoy?"

Almost intuitively, both men drew their wands.
