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

Because they witnessed Peeves' fate and confirmed that Peeves had not died.

So the ghosts and spirits all ran away.

As long as Lin Yu still has the Ten Thousand Souls Banner, they probably won't dare to provoke him again.

After all, they didn't want to end up like Pipi Ghost, who, despite their own unwillingness, was forced to pledge allegiance to Lin Yu.

That's absolutely terrifying.

Even that mischievous devil has turned into this, how dare they provoke him?

Lin Yu waved the Myriad Soul Banner and put the mischievous ghost back into it, then with a thought, he made the system put it away.

The system commented, "You're getting more and more adept at using me."

It's very sarcastic and unsettling.

Lin Yu shrugged and retorted in his mind, "Because you reduced a lot of my privileges and functions, otherwise I would probably be at the Foundation Establishment stage by now."

The system scoffed. Foundation Establishment? It's not that simple.

Five hundred, one thousand, two thousand, four thousand, eight thousand.

With each advancement in cultivation level, the required spiritual energy increases.

The system was already starting to worry: how could it help Lin Yu ascend to immortality as soon as possible so that he could also find liberation?

At this moment, seeing that Lin Yu had chased away the ghosts, Ron boldly approached again, poking Lin Yu's arm and asking, "What kind of flag is that? Is that really Taoist magic?"

Harry joined in, but he had never heard of any magic or Taoist practices.

Lin Yu glanced at Ron.

The latter said smugly, "I've heard people mention that your Eastern countries also have wizards, but you don't call them wizards there, I think you call them Taoist priests? And you don't have magic schools there, but rather sects?"

In fact, within the Harry Potter universe, China does have its own magical world.

Furthermore, according to the official setting (possibly added by Rowling herself outside the books), in the future year of 2010, the Chinese Quidditch team will make it into the Quidditch World Cup, and may even eventually win the runner-up title.

This is much better than the real Chinese men's football team.

Moreover, for example, Dumbledore's pet phoenix may actually have originated from China.

There are also some magical materials, such as redwood, which can be used as a wand material and is produced not only in the United States but also in China.

Lin Yu's magic wand is made of century-old peach wood from China.

Etc., etc.

It's just that different countries have different cultural styles.

So even Ron showed curiosity.

But Lin Yu doesn't understand any of that. He probably knows less about this world and his own country than Ron does.

So Lin Yuqian smiled and changed the subject, looking around before suddenly asking, "Where is this?"

Okay, the three children finally came to their senses; they seemed to be lost.

"Damn it, I knew you guys wouldn't listen to me."

A string of curses rang out, followed by a figure staggering over, with a cat beside him.

It was the administrator, Filch.

He rushed up to the three children, shouting smugly, "You've finally been caught red-handed! Especially you, I remember your name is Lin Yu, a Chinese guy. You could argue before, but let's see what you can say this time."

What Filch didn't notice was that Lin Yu had narrowed his eyes and his face had darkened.

Are they Chinese?

This is even worse than "Muggle" and "Mudblood," a derogatory term rife with discrimination.

Filch knows how to specifically target people's sore spots.

Lin Yu swiftly drew his wand, looked at Filch with a serious expression, and said, "Apologize, or die. Either apologize to me, or I challenge you to a duel to the death."

Filch was taken aback, then burst into a tirade: "You guys fouled first! This is the fourth floor! Dumbledore warned you before that you weren't allowed to come near here this year. You fouled yourselves!"

"That's irrelevant now," Lin Yu interrupted Filch angrily. "You'll pay for your stupidity. Even if you're stupid, you can't just spout nonsense. It's not like I didn't call you a Squib or a piece of trash who can't use magic. Damn it, you have to apologize to me, or I'd rather be expelled than let you pay. Don't think I'm joking; I'm the kind of person who pointed my finger at Snape and the entire Slytherin class and cursed them during the Sorting Ceremony."

That's right, that's why Lin Yu was willing to go to such lengths at any cost.

If people think he's easy to bully, he'll find it difficult to get anywhere in the future.

He was an orphan in this world, with no one to rely on.

Now she's studying abroad, at a magic school.

If he doesn't act a little crazy, who will respect him?

A good horse is ridden, a kind person is bullied.

He can only rely on himself.

He wanted everyone to understand one thing: he was not someone to be bullied, and anyone who dared to bully him should be prepared to have a piece of their flesh torn off.

He will never compromise or back down even a single step, never, because once he compromises, he will only be able to compromise again and again.

So Lin Yu pointed his wand at Filch's nose and demanded, "Do you want to apologize obediently, or do you want to duel with me? Make a choice. You filthy, insidious, jealous Squib."

Filch's already ugly face now showed a contorted and twisted expression.

He clearly cared a lot about being called a "dud" by Lin Yu, because it was true.

Lies don't hurt, but the truth is the sharpest knife.

Because he was a Squib, he became even more jealous of the students at the school.

Therefore, despite being a school administrator, Filch targeted students everywhere and even physically punished them.

For example, right now, he wants to seize this opportunity to lock these three children in the dungeon.

But when Lin Yu showed no sign of backing down, Filch became timid.

The reason is simple: since he's a Squib, how could he dare to duel a wizard? He doesn't even know a single spell.

"This is utterly absurd. I'll tell Dumbledore," Filch said, turning to leave. He realized he didn't want to provoke that madman.

"Stop!" Lin Yu roared. "Do you think I wouldn't dare kill you? I told you you have to apologize. I am Chinese, a true descendant of the Yellow Emperor. No one can humiliate me and then leave unscathed. Or do you think my wand is ineffective? What if I used a sword instead?"

With a whoosh, Lin Yu placed the magic wand in his left hand and pulled out the spirit sword given as a gift from the newbie gift pack from his system space with his right hand.

If he remembered correctly, the sword was named Yunlan, and it was a spirit sword of considerable quality.

Because he had already refined it with spiritual energy, it was already his magic weapon. Lin Yu could not only fly on the sword, but also kill enemies with it.

Lin Yu stared intently at Filch, a real glint of murderous intent flashing in his eyes.

At the critical moment, a figure quickly approached, his voice preceding his arrival, stammering, "No, no, no... do it!"

Lin Yu frowned, thought for a moment, and then quietly put the sword away.

He recognized the visitor as Professor Quirrell, the new Defense Against the Dark Arts teacher this year.

What Lin Yu truly feared was not Quirrell himself, but Voldemort, who might already be lurking in the back of his head.
