Being at Hogwarts, something's not right with this system.

Because Hermione's experience with the Cleansing Pill was so remarkable, the entire Gryffindor student body was in an uproar, surrounding Hermione in the common lounge area and asking her how she felt.

"I feel amazing right now. Not only has my skin improved, but more importantly, I feel so light and airy. It's like I can even cast some spells that I didn't know before, including the flying broom. I feel like I can fly into the sky now," Hermione said without any hesitation, expressing her true feelings.

This was her true feeling; she felt absolutely wonderful right now.

Wood squeezed through the crowd to Lin Yu and made a request: "Lin Yu, I would like to ask you to prioritize using the Marrow Cleansing Pill on our team members, or even sell it to us."

He definitely wants to sell, but Lin Yu hasn't decided on a price yet.

After all, things are valued for their scarcity. Now, the Marrow Cleansing Pill is something that belongs exclusively to him, which can be described as a monopoly.

How much should I ask for?

Furthermore, Lin Yu had a new idea. He suddenly wondered, since the Marrow Cleansing Pill could grant ordinary people the aptitude for cultivation, could it, in this world, allow ordinary people to become wizards? And could it turn Squibs into people with wizarding qualities?

If his idea comes true, he might create a major news story that could shake the entire wizarding world.

Just as Lin Yu was thinking this, there was a knock on the door of the Gryffindor common room.

Percy, as the prefect, went over and opened the door with a puzzled look on his face.

To everyone's surprise, Professor McGonagall was standing outside with a serious expression.

"Where's Lin Yu? Call him out quickly, Headmaster Dumbledore is waiting for him," Professor McGonagall stated her purpose directly.

The public rest area became quiet.

Lin Yu had no choice but to crawl out through the entrance hole, watched by everyone.

"You've gotten into trouble again?" Professor McGonagall looked at Lin Yu with a gloomy expression.

Lin Yu wanted to ask, why use "again"?

Now is not the time to try to get me into the team? Nor is it the time to praise me in the transformation class?

Lin Yu only dared to complain in his heart, but dared not say it out loud.

Professor McGonagall turned around and said, “Come with me. And don’t put on that innocent act. The feat you performed this afternoon has already spread throughout the entire castle. Now everyone knows that you embarrassed your professor in Snape’s class. Don’t forget you’re still a student. You must respect your professors. Don’t let outsiders think that we Gryffindor children are all ill-mannered. Understand, Mr. Lin Yu?”

It seems Professor McGonagall is genuinely a little angry.

Lin Yu muttered, "Who's so rude?"

Fortunately, he was speaking Chinese, which Professor McGonagall couldn't understand, so she could only roll her eyes.

Dumbledore was right; none of the Gryffindor children were immune to trouble.

She had thought Lin Yu was an exception these past few days.

But how could she forget what happened at the freshman banquet?

Since the principal's office was also on the eighth floor, Professor McGonagall quickly led Lin Yu to the office door.

It was a spiral staircase, at the top of which was a gleaming oak door with a brass door knocker in the shape of a griffin.

Professor McGonagall came to the door via the stairs, and the door opened automatically before she could knock.

Professor McGonagall turned to look at Lin Yu, gesturing for him to follow.

But actually, Lin Yu was a little nervous. It was impossible not to feel nervous, after all, he was about to face the greatest white wizard of modern times.

The main problem was that Lin Yu didn't know what had happened.

During this time, he also frequently saw Dumbledore at the teachers' table in the restaurant.

But this was our first time meeting in private.

Lin Yu didn't understand why Dumbledore would look for him instead of Harry.

What Lin Yu didn't know was that Snape came to see Dumbledore after dinner.

Let's rewind to a few tens of minutes ago.

Snape knocked on Dumbledore's office door and barged in.

"Snape? What brings you here?" Dumbledore wasn't ready to rest yet, but he had already changed into his pajamas.

Without the slightest hesitation, Snape asked directly, "I want to know, what's the deal with that student named Lin Yu?"

Dumbledore thought for a moment, then couldn't help but laugh. "I've heard, Severus. That naughty boy has really gotten you into a bad mood."

Under normal circumstances, Dumbledore would not call Snape "Severus". In the presence of outsiders, he would usually call him Professor Snape. Even when there were only two people, he would usually call him by his surname, which is Snape.

It seems Dumbledore was being sarcastic.

Snape's face darkened. "Do you know what he said that made me so furious? Damn it, who let him know about that incident? He not only seems to know who I am, my identity, but also why I had to submit to you. Dumbledore, I demand an explanation."

Snape, a former Death Eater, was a loyal follower of Voldemort.

His beloved Lily was killed by him.

Before Lily died, Snape was a Death Eater, always had been.

It was only after Lily's death that Snape decided to side with Dumbledore, and apart from Dumbledore, very few people know his true allegiance and identity to this day.

Including Harry, when Dumbledore learned that Harry was coming to school, he instructed Snape to protect Harry secretly, rather than openly taking care of him.

In other words, Snape never intended to take care of "Potter" while protecting Harry's life.

Because Snape hated Harry, yes, he hated Potter.

How could he not hate it?

But he also deeply loved Lily, Harry's mother.

Snape's emotions were complex. He pursued and yearned for the true meaning of dark magic, but lost himself along the way and became a Death Eater. He also got separated from his beloved Lily along the way.

Even though he had come to his senses, he had still lost his beloved forever.

This regret was a lifelong pain for him.

But a student, right in front of him, tore open his wound and sprinkled a bag of salt on it.

How could Snape not be furious?

Dumbledore had just learned of this as well, and he had to put away his joking tone and say seriously, "Snape, I don't know what happened. Even I know nothing about that child."

"Do you think I would believe you?" Snape simply stared coldly into Dumbledore's eyes.

Dumbledore explained earnestly, "I checked the register, and I found that this child wasn't initially listed in Hogwarts' records of births. Snape, he's a child who shouldn't have been born. But he still received the notification, and do you know what that means?"

Dumbledore paused here, took a deep breath, and continued, "This is the choice made by Hogwarts, this castle. We all know that Harry Potter bears an important mission. If Voldemort returns, we will have to rely on a child who is not yet an adult to shoulder this heavy responsibility. But I have a feeling, Snape, that child who shouldn't have been here is perhaps more important than Harry, the savior."

"He may be the only wizard to date who has the potential to catch up with, or even surpass, the four great founders of Hogwarts."
