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

In a dark alley in London, England, a boy sat in a corner, sighing helplessly.

"Several days have passed, it seems I really can't go back," Lin Yu sighed helplessly.

No one would believe that something so bizarre had happened to him.

He was originally a middle-aged man in his thirties, just an ordinary employee of a small company.

One night, he worked overtime until late at night, but on his way home, he was involved in a car accident and died on the spot.

But he did not die; instead, he opened his eyes and found himself in London.

To Lin Yu's surprise, he turned into a child who looked only ten years old.

He discovered that his body was still his own, only his physical age had changed to that of a child.

At first, Lin Yu thought he had been reborn and returned to the age of about ten years old.

But he did make a phone call. He went to a restaurant and borrowed a landline from a kind person to call back home. He still remembered his parents' old phone numbers.

(I've revised this part. I'm not sure if my description was wrong? The "telephone" refers to a landline, not a cell phone. Please don't try to explain it to me anymore. I said the protagonist borrowed a cell phone or a mobile phone. It was a landline.)

It turned out that the number he dialed was not in service.

Lin Yu then realized the seriousness of the problem; it seemed that all the people he used to know were now nowhere to be found.

At the same time, he had a premonition that he was not reborn at all, otherwise he would never have appeared on the streets of London, England, since he had never been abroad when he was a child.

Later, because Lin Yu had no identity information, he was basically an undocumented person in London, and could only hide and live by scavenging and begging.

There's nothing we can do about it. After all, at his age, even if he still remembers some simple English words, no one will hire him.

Even if I wanted to work illegally, no one would hire me.

Fortunately, he still had the memories of an adult, so he was able to barely get by.

"But when will this end?" Lin Yu looked up at the sky, feeling as if his life was about to end.

Just then, as if hearing his mournful cry, a bird flapped its wings and flew over.

Upon closer inspection, Lin Yu realized that it was no ordinary bird, but a pure white owl.

Actually, this is called a snowy owl, also known as a white owl, a type of owl with white feathers.

The owl, with an envelope in its beak, landed directly in front of Lin Yu.

Lin Yu ignored the envelope and stared intently at the snowy owl in front of him, his eyes practically glowing green.

"I wonder if owls are protected animals in London, and if it's illegal to eat them?" Lin Yu said, tears welling up in his eyes.

The snowy owl stared wide-eyed at Lin Yu warily, as if it were quite human.

The snowy owl opened its beak and dropped the envelope, then turned and flapped its wings and flew away before Lin Yu could do anything.

It just can't speak, otherwise it would definitely hurl very vulgar insults.

These young wizards are terrifying! I deliver a letter to you, and you want to eat me?

Lin Yu looked up with a regretful expression as the roast chicken (or bird) he had just gotten his hands on flew away.

A moment later, Lin Yu remembered something, looked down at the envelope on the ground, hesitated, and then reached out to pick it up.

When Lin Yu opened the envelope and took out a letter, he used the dim moonlight to barely make out the contents of the letter with the English vocabulary he had almost returned to the school, and read it aloud haltingly: "Hogwarts School of Witchcraft and Wizardry".

This is where the other party's identity is signed.

"Headmaster: Albus Dumbledore."

Then, below the headmaster's name, there is a parenthesis describing Dumbledore's honors and status.

For example: (Sir Merlin, First Class Order of the Order of the King, Chief Wizard of Wizengamo, President of the International Federation of Wizards).

Then comes the main text.

"Dear Mr. Yulin (foreigners generally put the first name first, then the last name), we are pleased to inform you that you have been admitted to Hogwarts School of Witchcraft and Wizardry. Enclosed is a list of required books and supplies. The term begins on September 1st. We await your reply by owl by July 31st. Yours truly, Vice-Headmistress Minerva McGonagall."

Then an attachment fell out, which was a list of the books and items mentioned in the letter.

Lin Yu was stunned after reading the contents of the letter.

"Hogwarts? Dumbledore? Professor McGonagall?" Lin Yu's eyes widened slowly. Although he wasn't a die-hard fan—he hadn't read the original novel—he had seen the movies.

After all, that's Harry Potter.

"I was wondering why I couldn't get through to the old phone number at home. So I didn't just get reborn, I time-traveled?" Lin Yu jumped up from the ground and then bent down to pick up the envelope.

The envelope was addressed to: "To Yulin, who is currently living in a back alley in London."

Goodness, they even know the exact location where he's now homeless?

As expected of a magical world.

"Interesting, interesting, so interesting!" Lin Yu's face was flushed with excitement.

He never expected that this place was actually the world of Harry Potter, and that magic was hidden beneath the surface of this world.

This is a genuine magical world.

Lin Yu couldn't help but excitedly mutter to himself, "Looks like I'm about to become a wizard? It seems today is July 31st (actually, it's the evening of July 23rd). As long as I wait until September 1st, Hogwarts will start, and I can go to school."

Just then, a voice suddenly rang in Lin Yu's mind: "Congratulations, host, you have met the requirements to join a sect. The auxiliary system has been activated."

"A system?" Lin Yu's eyes widened again, and he exclaimed in surprise, "This is truly an unexpected delight! I didn't expect that after being homeless for a few days, I'd be rising to power? After all, I'm a transmigrator; isn't it normal to have a system by my side?"

However, Lin Yu may have overlooked one thing: the system mentioned "sect" rather than "school".

After a moment of excitement, Lin Yu asked the system, "So, system, what functions do you have? Does it mean you can let me master magic ahead of time?"

"Magic?" The system's voice sounded somewhat confused. "What is that? Didn't you already join a sect? Why are the sect elders and other disciples nowhere to be seen? And where is your fiancée, Nalan Yanran, who was supposed to break off your engagement?"

Lin Yu finally sensed something was wrong and tentatively asked, "Nalan Yanran? A annulment? Dude, are you in the wrong world? Isn't this the plot of Battle Through the Heavens?"

Is he being mistaken for Xiao Yan?

I will not underestimate a young man's potential.

The system fell silent, as if it had sensed something.

After all, this is London, not a sect in a fantasy world.

Just when Lin Yu thought the system would no longer respond, it spoke again: "No, impossible, absolutely impossible. This is a fantasy world, and you are Xiao Yan."

Lin Yu couldn't take it anymore: "Damn it, a real man doesn't change his name or surname. Listen carefully, my name is Lin Yu. Who the hell is Xiao Yan? Either acknowledge me as Lin Yu, or break the bond. You're so spoiled."

Anyway, he's going to school to become a wizard, and he'll be studying magic.

This system seems to come from a fantasy world, so whether it exists or not doesn't seem to make much difference.

Unexpectedly, the system whispered, "Once the system is bound, it cannot be unbound unless you ascend to immortality; otherwise, you're stuck with it forever."
