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

In front of Hagrid's hut, in the open space, Lin Yu and Hermione stood together, facing Professor McGonagall's furious criticism.

God knows how terrified Professor McGonagall was when she heard the news.

Even now, Professor McGonagall's eyes are still a little red.

It's hard to imagine that this professor, who has always given people a stern impression, would have such emotional moments.

It's clear that she really liked those two students.

But they went too far.

"That's the Black Lake! And how dare you provoke mermaids? No one but Dumbledore can trespass into mermaid territory!" Professor McGonagall shouted, rarely yelling at her students with such agitation.

After all, she wasn't Snape. Professor McGonagall was the one who truly treated every student equally, never caring what house they came from or what bloodline they were.

She would punish anyone who dared to make a mistake, even if they were a Gryffindor student.

Even if a child is a Slytherin, she is equally generous with praise and bonuses if they behave well.

Therefore, Professor McGonagall is the good teacher who is respected by all the students.

But now, Professor McGonagall was absolutely furious: "By Merlin, I'm going to punish you severely! I'm going to deduct 100 points from Gryffindor, 50 points from each of you, otherwise you'll never remember how serious this is."

Professor McGonagall herself is the Head of Gryffindor House.

But she still didn't hesitate to teach Lin Yu and Hermione a lesson.

She knew that once those 100 points were deducted, there would be no chance for her to compete with Gryffindor in this year's House Cup.

But she didn't care; she preferred to teach these two unruly problem children a lesson.

If they can restrain themselves in the future, behave themselves, and stop courting disaster, she'll feel it was all worth it.

At least she no longer has to live in fear with them.

Even now, Professor McGonagall's voice was trembling, and her heart was still pounding.

Standing nearby, Dumbledore, unusually, dared not interrupt when his old colleague was getting angry.

Hagrid kept his head down, as if he were the child who had made a mistake.

After all, it was Hagrid who gave Lin Yu and the others the fishing rods, and as the game field keeper, his task was to guard the Forbidden Forest and Black Lake.

Right under his nose, Lin Yu and Hermione almost got into trouble.

Hagrid also felt guilty; he shouldn't have let them go fishing. See? As expected, something bad happened.

"Professor McGonagall," Hermione looked up, wanting to explain, but seeing Professor McGonagall's worried expression, especially her reddened eyes, she couldn't say a word.

Lin Yu frowned. He knew she was worried about them, but after thinking it over, even if not for himself, he couldn't let them lose a hundred points for Hermione's sake.

Lin Yu himself may not care about the so-called Academy Cup, but he knows that the Academy Cup is very important to the four major academies.

Students from every college want to win the College Cup for their college, as it represents a collective honor.

And if they caused Gryffindor to lose a full 100 points because of them, it's easy to imagine that they will be targeted when they go back.

Lin Yu then looked up and suddenly said, "Professor McGonagall, I know you're worried about us and concerned for our safety. But what if I said we have absolute confidence in our own abilities?"

"What kind of strength?" Professor McGonagall shouted even louder when Lin Yu dared to talk back, "You've only been enrolled for a week, tell me what kind of strength you have?"

Even knowing she meant well, Lin Yu was still unhappy.

"Lin Yu," Hermione said, reaching for Lin Yu's hand, her eyes pleading.

But Lin Yu stood in front of Hermione and said, "I can't let you deduct our points; that would make us the sinners. I don't care, but Hermione can't. She was dragged along by me; she can't take the blame. In that case, let me show you my true strength."

As he spoke, Lin Yu took out his wand. Of course, he wouldn't attack his professor, after all, she was the head of Gryffindor, and she was only doing it out of concern for them.

Lin Yu turned around, raised his hand and pointed his wand towards the distant Black Lake. Facing the open space ahead, he chanted, "Laser Beam."

He used the magic he had developed, and with a "whoosh," a laser shot out from the tip of the wand, arriving above the Black Lake almost instantly.

As Lin Yu used his magic wand as a guide, the laser beams were sent into the Black Lake.

Strangely, the Black Lake appeared calm and still, as if nothing had happened.

But Dumbledore gasped and murmured, "What terrifying power."

Professor McGonagall's eyes widened as well.

Only Hagrid and Hermione were at a loss.

Only two old wizards seemed to realize that the laser beam, which didn't seem to cause much of a stir, actually had such concentrated power that it pierced right through the Black Lake.

That's a laser; its power isn't explosive, but penetrating.

What if it were a person? That blow would be enough to pierce the other person's body, leaving a horrible, bloody hole.

"Is this magic you invented?" Dumbledore finally spoke, asking Lin Yu.

Because Lin Yu shouted the spell in Chinese, it was clearly not a spell that existed in Hogwarts or even in the entire British wizarding world.

Otherwise it would be in English.

Lin Yu withdrew his magic and looked at Dumbledore: "Of course. Besides, I've already mastered all the spells and magic of my first year. And I'm also researching how to more easily control elemental magic. For example, wind."

Lin Yu simply uttered the word "wind," and a small wisp of wind immediately formed at the tip of his wand, without spreading outwards, just like a small tornado condensing at the tip of the wand.

Dumbledore and Professor McGonagall looked at each other, both able to see the shock and surprise in each other's eyes.

In fact, Dumbledore had already vaguely sensed Lin Yu's secrets and extraordinary abilities, but the talent Lin Yu was displaying at this moment still shocked him.

A first-year student, and only a week into the semester, has not only mastered all the spells for first-year students, but can even develop new spells on his own?

Are you Merlin reincarnated?

But only Lin Yu himself knew what was going on. He had already realized some of the truths of this world, namely the power of idealism.

The so-called idealism, once it reaches its peak, is so powerful that one's words become law.

I said, “Let there be light,” and there was light.

My thought is the law.

Lin Yu, being a Chaos Dao Body, was naturally blessed and favored by the Heavenly Dao.

This is yet another idealistic magical world.

So it was incredibly easy for him to develop new magic.

Of course, the premise is that he also needs to give the world a conceptual meaning.

For example, with the spell "laser beam," he needs to let the world know his thoughts and what he wants to do; he can't just let his imagination run wild.

In that respect, Lin Yu is simply a genius.

Even so, or rather, precisely because of this, Dumbledore pondered and said, "In that case, you are even less likely to act recklessly. I agree with Minerva's idea, and I'm going to deduct one hundred points from each of you."

Lin Yu: I'm fucking eating a melon.
