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

To Lin Yu's surprise, because he had triggered the storyline of the magic stone ahead of time, the system also issued a corresponding task.

Although the system's description was hesitant and inconsistent, sometimes referring to it as a magic stone and other times as a blue lotus core fire.

However, the reward for the mission is very clear: as long as Lin Yu obtains the magic stone before others, he will receive the genuine 'True Azure Lotus Earth Core Flame'.

Furthermore, Lin Yu had a question he had wanted to ask for a long time: "System, isn't this actually the power system of Battle Through the Heavens? Whether it's the Chaos Dao Body or the Innate Sacred Body Dao Embryo, isn't this Chen Dong's worldview? And which novel's combat system do the cultivation techniques come from?"

Lin Yu had actually felt a sense of unease for a long time.

Battle Through the Heavens is a world of Dou Qi (fighting spirit), and the idea of ​​Dou Qi turning into a horse is a famous meme.

Also, the realms in Battle Through the Heavens are Dou Shi, Da Dou Shi, and so on, with the highest being Dou Di.

But what about Lin Yu? He and Hermione are at the conventional cultivation level, with their ultimate goal being to ascend to immortality.

It must have been in complete chaos long ago, right?

System: "Whose fault is it?"

Lin Yu: "Are you going to blame me? Didn't you get the world wrong? You're the one who attached yourself to the wrong target, aren't you?"

System: "Heh. My host is you; you've transmigrated to the wrong world."

I definitely can't take the blame for this, and the system really couldn't possibly have made a mistake with the target. Just kidding, he was sent down from that terrifying supreme power.

Even a magic school like Hogwarts wouldn't mistake a young wizard, let alone them.

As for Lin Yu's notification letter, one more is better than one less, right?

Lin Yu's conversation with the system was inaudible to others, but Hermione, standing nearby, wore a thoughtful expression.

Time travel? World travel? What do these all mean?

Also, does Lin Yu's mission require obtaining a magic stone?

"We can't go to Dumbledore," Hermione suddenly said. "After all, this is all just speculation. What if we're wrong? Slander a professor? Are you all crazy?"

Harry and Ron looked at Hermione in confusion. "You weren't like this just now."

"In short," Hermione said to Harry and Ron with a serious expression, "this is a secret only we know. No one can tell anyone until we have sufficient evidence, and we certainly can't let Professor Snape know we're investigating him. I don't want all four of us to be expelled from school; that would be a serious matter."

Harry shuddered. He certainly didn't want to be expelled, and he certainly didn't want to go back to the Dursleys.

Ron seemed to have realized something as well, and a look of hesitation appeared on his face.

His mother was very cruel; she was a real tigress.

"And then what? What should we do now?"

"Go back and go to sleep."

So the four people, who had been so excited before, returned to the Gryffindor common room with sullen expressions.

Before entering, Lin Yu and Hermione exchanged a glance and said at the same time, "We have something to do, you should go back first."

Ron complained to Harry, "They've gone out to play by themselves again."

Harry, however, said calmly, "Shouldn't we be used to it by now?"

That's how the young couple has been living all this time.

After Harry and Ron climbed into the common room, Lin Yu and Hermione turned around and went back to the Room of Requirement.

They had originally decided to rest today and not rush into cultivation.

Therefore, they did not practice spiritual cultivation.

Hermione said, "Are you going to steal the Philosopher's Stone?"

Lin Yu wasn't surprised and said, "You heard that."

Hermione nodded and began to calculate: "What's in that room? There can't be just one Cerberus guarding the Philosopher's Stone. Otherwise, it would be too easy."

You actually said it was simple?

However, if Snape is the suspect, then Hermione is right; a mere three-headed dog cannot stop a Hogwarts professor.

Not to mention, Snape was also very skilled in dark magic and potions.

He has countless ways to take down a dog, even a three-headed one.

"Perhaps we can try to investigate tonight. Even if we don't get the Philosopher's Stone immediately, we can find out what secrets or traps are inside," Hermione suggested.

Lin Yu looked at her with amusement.

Hermione asked curiously, "What's wrong? Why are you looking at me like that?"

Lin Yu shook his head, reached out and pulled his girlfriend into his arms, saying, "You really like adventure now?"

It seems that the first time we went fishing at Black Lake, she was the one who asked to fly into Black Lake.

How could he not know that Hermione has such a lively personality?

Hermione nestled comfortably in Lin Yu's arms and said in a low voice, "Isn't this all for you? Of course, I also really enjoy going on adventures with you; it's a lot of fun."

The premise is that he's with me.

If it were just Hermione by herself, she preferred to go to the library and sit there all day without getting bored.

Reading is her pastime.

But with Lin Yu around, she felt that life was colorful and everything seemed interesting, and she wanted to try everything.

"What time are we going on our adventure?" Lin Yu asked with a smile.

Hermione thought for a moment and said, "We'll have to wait until after curfew, right? Also, we need to avoid the warden, Filch, and avoid running into other teachers."

The two of them agreed to that.

However, they did not leave the House of Requirement. Instead, they stayed there to enjoy their time together, so that they wouldn't feel uncomfortable being too intimate in the common area with other people around when they returned home.

It's different here; you can hug someone if you want, and kiss them if you want.

As long as they don't eat forbidden fruit, they can do whatever they want.

And so it went until after 10 p.m., when Lin Yu and Hermione quietly came out of the Room of Requirement.

Feeling guilty, they listened for a while until they were sure there was no noise outside before finally coming out.

"Don't take the stairs," Lin Yu whispered.

The two men exchanged a glance, and each of them drew a long sword.

Lin Yu also secured a Qiankun Ring for Hermione, and gave her the Yunlan Sword he had previously owned, while he himself exchanged it for a Tiangang Sword.

The two stepped onto the sword at the same time, and then floated up into the air.

They flew down from the eighth floor on their swords and arrived directly on the fourth floor.

Then they turned into the fourth-floor corridor, passed through the long armored passage, and came to the door again.

Lin Yu turned to look at both sides of the corridor, while Hermione took out her wand and chanted the door-opening spell at the door lock: "Alohomora open."

With a "click," the door lock was opened.

The two jumped off their swords, each grabbed a sword, and went into the room.

Then the two saw a huge, three-headed dog slowly rise from the ground.

It was a large, jet-black dog with three heads that opened their gaping maws, seemingly about to attack or let out a loud bark.

Lin Yu raised his hand, ready to thrust out his sword.

"Don't kill it," Hermione whispered, "or we'll be discovered. Watch me."

Hermione said, raising her wand and flicking it: "Faint."

This three-headed dog is clearly a magical creature, and generally has some resistance to magic.

But Hermione was no ordinary person. With a single spell, the three-headed dog felt incredibly tired and collapsed to the ground with a thud, falling into a deep sleep.

If the professors saw this, they would probably be shocked.

It's worth noting that even Snape and Quirrell couldn't use magic to subdue the three-headed dog, which is why Snape was injured, and Quirrell in the original story had to find another way to cleverly bypass the dog's protection.

It can be seen.
