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

With Quirrell's arrival, Filch secretly breathed a sigh of relief, and the tense atmosphere eased slightly.

But Lin Yu kept staring intently at Filch, as if to say that this matter was not over yet.

Professor Quirrell approached the group, panting, and said, "They...are all freshmen, and...today is...the first day of school. It's understandable."

Perhaps due to his panting, Quirrell, who already had difficulty speaking, seemed to stutter even more.

Filch mumbled in agreement, "I guessed so, which is why I was planning to teach them a lesson and let them go."

He's just trying to save face for himself.

But Lin Yu coldly replied, "Don't make me say it too many times. You still owe me an apology. Otherwise, even if it means getting expelled, I'll ask Dumbledore for a duel with you."

Filch's face was grim, but Lin Yu's attitude made him hesitant to gamble that he wouldn't do it.

So, under Professor Quirrell's curious gaze, Filch still whispered, "I'm sorry, I shouldn't have called you Chinaman. I won't do it again."

Lin Yu then snorted coldly and said to Harry and Ron, "Let's go."

The three little ones walked past Quirrell and Filch and left the fourth floor.

As they went down, Ron was still exclaiming in amazement, "Lin Yu, you're amazing! That's Filch, even Fred and George have a lot of trouble dealing with him."

Lin Yu calmly replied, "Because we understand the rules. As long as we are in the right, we are invincible. And as I said before, I don't like hearing discriminatory and derogatory terms like 'Mudblood' or 'Muggle.' This guy dared to mock my entire nation and country, which is absolutely intolerable. If he really dares not to apologize, I will fight him to the death."

Although this is not Lin Yu's own world, he will never compromise or tolerate it.

Moreover, he also knew that people in the magical world were very snobbish.

If people know you're easy to bully, then just wait, there will be an endless stream of people trying to bully you.

Only by making yourself strong and letting people know that you are powerful and not to be trifled with will they not dare to mess with you.

Harry and Ron exchanged a glance, silently warning themselves that they must never provoke Lin Yu again, otherwise this guy could be really scary when he went crazy.

This was just a minor incident, and Harry then changed the subject: "What secrets are hidden in that room on the fourth floor?"

"I don't know either," Ron shrugged.

Only Lin Yu guessed what it was—without a doubt, it was the Philosopher's Stone that Hagrid had brought back for Dumbledore from Gringotts vault.

No wonder Quirrell happened to appear; perhaps he was wandering around nearby? (Actually, the Defense Against the Dark Arts classroom is on the fourth floor.)

I just don't know why Quirrell spoke up for them.

"Alright, let's not talk about that now. We should go to the restaurant now. After lunch, we need to prepare for our afternoon classes," Lin Yu reminded the two of them, while taking out Hermione's class schedule, which showed that they had a herbalism class from 2:00 to 2:45 pm.

Compared to regular schools, Hogwarts' curriculum is incredibly easy.

Of course, the courses for young wizards are much more difficult than those for ordinary people.

After all, they are going to learn magic.

So the three of them headed to the restaurant. On the way, Ron kept asking Lin Yu how he managed to turn a match into a needle.

Lin Yu casually replied, "Practice hard, Ron. If you don't have the talent, make up for it with hard work. Diligence can compensate for lack of talent."

Ron then turned to Harry and asked, "Was he calling me stupid?"

Harry glanced at Ron: "Looks like you're not so stupid after all."

Ron scratched his head, feeling that Harry was also subtly criticizing him.

Lin Yu's lips curled up. Although he was mentally an adult, he felt pretty good right now.

When the three arrived at the restaurant, they noticed that due to scheduling issues with some classes, many people were missing from the tables around the four colleges.

This also made the huge auditorium appear sparsely populated.

At the same time, they saw that the other new students in the same college were already in place, and only they were missing.

The three of them walked over, and naturally, Harry and Ron sat opposite Hermione, while Lin Yu sat down in the empty seat next to Hermione.

Neville was talking to Seamo.

Hermione, who was reading a book, looked up when Lin Yu approached and said, "How did you manage that? Did you read through the entire textbook beforehand? Otherwise, how could you turn a match into a needle so easily?"

Lin Yu glanced at Hermione, then at Ron across from him. "No wonder they're the original couple," he thought. "They have the same problem."

The latter was completely unaware, and was discussing with Harry what to have for lunch.

In fact, Hogwarts' three meals a day are fixed, and everyone gets the same combination. Before they could finish speaking, a plate appeared on the table in front of them, with bread, roasted potatoes, a sausage, and a pumpkin soup on it.

Lin Yu frowned, wondering if he should cook for himself to improve his eating habits.

Or he could open a small shop in the restaurant? Like selling grilled cold noodles or grilled gluten?

Maybe we can make a fortune.

But it's more likely that Filch will take the opportunity to retaliate, such as by reporting him to Dumbledore.

At the same time, Lin Yu answered Hermione's question, saying, "I did read those books beforehand, but the key isn't there, it's talent, Hermione. I don't know how to explain it clearly, but after listening to Professor McGonagall's lecture, I felt that I could do it."

Hermione looked at Lin Yu with a resentful expression and tentatively asked, "Are you trying to say I have no talent? Or are you trying to say you're smarter and more capable than me?"

Kids are bound to be a little competitive.

What's more, she's Hermione.

Lin Yu said helplessly, "Everyone has their strengths and weaknesses. Hermione, you are very smart, but you also have shortcomings. For example, me, I also have my shortcomings."

"For example?" Hermione stared at Lin Yu and continued to press, "What are you not good at?"

Lin Yu was just being polite, but he didn't expect Hermione to take it seriously. He could only helplessly say, "For example, if I were a boy, there would be things that girls know but I don't."

"Pah!" Hermione, realizing she'd been given the runaround, spat a small spit and turned away to eat her lunch.

Lin Yu breathed a sigh of relief, picked up the plate in front of him, grabbed a piece of bread, and took a big bite.

He was glad this wasn't the Middle Ages, so the bread was soft and fluffy, unlike the dark bread that often had pebbles mixed in.

Overall, lunch was fairly filling.

During this time, Harry's owl, a snowy owl he named Hedway, flew in. It first landed on Harry's shoulder, gently pecked at his ear, then landed on the table, snatched a sausage from Harry, and flew away.

Just as Lin Yu was feeling envious, his own dog, Hulu, crawled out from under the dining table to his feet, rubbed against his trouser leg, and then climbed up on its own, snoreling in his arms.

Hermione was incredibly envious of how affectionate Huru was with Lin Yu.

She thought that she would buy a cat next year.
