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

To prove that he could indeed help Harry, Hagrid led the two children to the backyard of the Leaky Cauldron, introducing him to the people they had just met.

"You don't need to remember the others, but Professor Quirrell, who was just now, will be your Defense Against the Dark Arts professor this year," Hagrid said, describing Professor Quirrell's appearance.

Well, there was indeed a wizard with a purple turban wrapped around his head and who spoke haltingly among the crowd surrounding Harry.

Looking back now, Lin Yu realized that it was indeed Quirrell from the original story, a pitiful and self-destructive man.

It seems that Quirrell is already possessed by Voldemort.

On the back of his head.

Thinking of this, Lin Yu couldn't help but shudder.

So, does that mean I've been targeted by Voldemort?

But then he thought about how he was just a nobody, and Voldemort might not even look down on him.

Lin Yu felt relieved again; otherwise, he would still be a little scared living alone in the room at the Broken Cauldron Bar at night.

Wouldn't it be unfair if we were attacked by Death Eaters?

He really wants to see this magical world for himself and become a qualified wizard.

After Hagrid opened the entrance to Diagon Alley, Harry was astonished as they arrived at the tip of the iceberg of this magical world.

But don't underestimate Diagon Alley, because it is the only commercial hub in all of Britain where magic and wizards gather.

In fact, perhaps surprisingly to many, it is the magical world that has always been trying to avoid being discovered by Muggles.

It's as if the wizarding world is afraid of Muggles, whom they look down upon.

After all, burning witches was a common practice in the Middle Ages.

Eventually, the wizarding world enacted a secrecy law.

Lin Yu has been reading those textbooks during this time, such as the history of magic and magic theory, and he is also memorizing some magic spells.

Because he couldn't test the effects of those spells, he didn't know if he had mastered them.

"Let's go to Gringotts first," Hagrid said, striding ahead while keeping a close eye on the two children's pace to avoid accidentally leaving them behind or stepping on them.

After all, he was too tall.

Harry said somewhat embarrassedly, "But Hagrid, I don't have any money."

Since he was brought here to buy school supplies, he would have to pay for his own things, but Harry, due to his own circumstances, probably didn't even have a penny on him.

Even Lin Yu was able to beg for a few dozen pence before.

Harry also subconsciously glanced at Lin Yu beside him.

As one of the few peers who showed him kindness, Harry felt inferior even though he hadn't become friends with Lin Yu yet.

Lin Yu misunderstood Harry's meaning and said without thinking, "I can lend you some money, it's okay if you don't pay it back."

After all, this is the protagonist. Even without the system mission, Lin Yu wanted to get along well with this boy who had survived such a close call.

Putting everything else aside, this investment requires only a small amount of money, making it a sure-fire way to make a profit.

Let me buy a friend slot first.

Unfortunately, just as Harry's face turned bright red, unsure whether to thank her or politely decline,

Hagrid spoke, his voice loud and seemingly filled with astonishment: "Harry, what are you saying? You actually think your parents didn't leave you an inheritance?"

To Harry's surprise, Hagrid knew better than Harry himself that his parents had left him something, and it was a considerable inheritance.

So the group went to Gringotts.

Lin Yu had been here once before, but even if he came again, he still felt that Gringotts was simply full of the stench of money, vulgarity, and utterly vulgarity. The magnificent and resplendent scenery was as if the interior was made of gold.

Lin Yu cursed inwardly, "I want the smell of money too, you bastard."

If only it were his.

Hagrid led Harry to the counter and explained his purpose: "Harry Potter wants to open the vault and take some money."

A goblin peeked out and looked at Harry, who was standing next to Hagrid, and asked, "Did you bring your keys?"

Gringotts only recognizes keys, not people. If you have someone you trust enough, or even a pet, they can use the key to take money out of your vault.

For example, Sirius Black once had Crookshanks (Hermione's cat) take the vault key to retrieve his money and bought Harry a broom, and an expensive Firebolt at that.

The reason for this is that wizards can concoct magical potions called Polyjuice Potion, which allows them to completely transform into other people's appearances with almost no chance of being detected.

That's why the goblins of Gringotts made a rule that they only recognize keys, not people.

They certainly won't trust wizards anyway.

Lin Yu deliberately stood behind Harry and Hagrid, as if remembering something, and said, "I'll wait for you outside."

He recalled the original plot and knew that Hagrid would have to help Dumbledore retrieve the Philosopher's Stone, since the plot of the first book revolved around the Philosopher's Stone.

The Philosopher's Stone was created by the famous medieval alchemist Nicolas Flamel. Whether in Lin Yu's previous life in the real world or in this magical world, Nicolas Flamel and his Philosopher's Stone exist.

It is said that the magic stone can turn stone into gold and transform the rotten into the magical.

Even in this magical world, the Philosopher's Stone is not only a real magical item, but people also believe that it can grant immortality.

For example, Nicolas Flamel in this world used a magic stone to grant himself and his wife a lifespan of over six hundred years.

Even now, Nicolas Flamel still lives somewhere.

In fact, Nicolas Flamel died because he decided to destroy the Philosopher's Stone after this incident.

Lin Yu was beginning to lay the groundwork for his future, such as getting to know the protagonist of this world and building a good relationship with him.

But he didn't want to get involved in those events that sounded really serious without even realizing it.

For example, Voldemort.

Lin Yu doesn't want to confront that big devil, at least not right now.

Just kidding, he's not the main character. The Demon King is left to the hero to deal with.

For example, Harry? For example, Neville?

So Lin Yu stayed outside, while Hagrid took Harry and followed the goblins to the vault to retrieve their belongings.

During this process, Lin Yu contacted the system in his mind: "Now that we've arrived at the 'Monster Mountain Range,' shouldn't my rewards be distributed?"

The system responded: "Task completed, reward: Supreme Daoist Devouring Heaven Divine Skill."

Immediately afterwards, a memory was implanted into Lin Yu's mind out of thin air; it was all about the Devouring Heaven Divine Art.

Because the memories were directly implanted into Lin Yu's hippocampus and became his memories, it was as if Lin Yu had seen them countless times. He wouldn't say he could recite them by heart, but he certainly remembered them vividly.

As long as he doesn't forget this memory, he won't forget a single word.

This also gave Lin Yu a profound understanding of the Devouring Heaven Divine Art.

"As expected, the magic of this world cannot be absorbed. There's no hope for it after all."
