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

To Lin Yu's surprise, Huru returned just as he was about to have lunch on the first floor of the Broken Cauldron Bar.

Lin Yu was shocked: "How long has it been? You delivered the letter to Hogwarts? Or did you lose it?"

If the reply is lost and Hogwarts doesn't receive it, can he still go to school?

Therefore, Lin Yu was very worried.

Then Tom laughed and said, "Your cat is very clever. It probably took the letter to the post office for you. They can use an owl to deliver it."

Lin Yu then suddenly realized what was going on.

At the same time, he wasn't sure if it was just his imagination, but he felt like he could see a hint of disdain in Hulu's eyes. Surely it wasn't contempt?

Huru shook its head, as if it was very worried about the future of its silly master, but it still rubbed against Lin Yu's trouser leg and then jumped onto Lin Yu's lap and sat down cross-legged.

Lin Yu patted Huru's head and looked at Tom.

Tom brought him a flatbread and a serving of raw liver.

Lin Yu sighed silently.

Even though he had accepted the fact that he had traveled to the Harry Potter world, and only today did he realize that today was not July 31st, but July 24th.

Looking back now, he must have transmigrated on July 10th and struggled to survive in this world for fourteen days.

But he still couldn't get used to the food here.

Those who know, know. British food, whether it's good or bad is another matter, it's mostly just passable.

For the British, food may be defined as simply filling their stomachs, so they don't care whether it tastes good or not.

Lin Yu tried to bring the raw liver to Hu Lu.

Huru turned its head and jumped off Lin Yu's lap, refusing to eat.

Lin Yu reluctantly took a big bite of the hard-baked flatbread. The thought of having to eat this kind of food for almost forty days made him feel very depressed.

After a quick lunch, Lin Yu rubbed his stomach and went back to his room upstairs.

He didn't need to worry about Huru's whereabouts; his cat seemed to be even smarter than him.

Hopefully, Hulu will bring back more when he goes hunting?

"Or maybe we should go back to the pet store this afternoon and ask Huru what his favorite food is?" Lin Yu muttered.

I was so focused on buying cats and other things that I forgot to prepare more food for Huru.

I wonder if they still have cat food or cat treats?

Fortunately, Lin Yu bought a cat instead of an owl.

Owls are birds of prey, and their diet consists mainly of meat.

Maybe cats are easier to care for?

Upon reaching his room upstairs, Lin Yu lay down on the bed, staring at the ceiling and thinking to himself, "I never imagined I would transmigrate into the world of Harry Potter, and even have the honor of attending Hogwarts."

He once fantasized that when he was eleven years old, he would receive a notice delivered by an owl.

Unfortunately, the real world is not a magical world.

His wish could only remain unfulfilled.

But now things are different; he's really going to become a wizard.

I'm so excited just thinking about it.

But just then, the system's voice rang in Lin Yu's mind again: "Host, have you forgotten something? Do you still want the Chaos Dao Body?"

The system was very frustrated. Most of its permissions were blocked, leaving it with almost nothing. It even had to be reduced to being a backpack for its host.

Moreover, it was noticed that Lin Yu was so focused on going to Hogwarts that he had even forgotten about the Chaos Dao Body, the supreme Dao Body.

It's such a waste.

If this were in a fantasy world, the emergence of the Chaos Dao Body would be earth-shattering, almost causing a cataclysmic change in the world.

At that time, countless sects will search high and low for the Chaos Dao Body, paying countless prices to recruit it into their sects.

But Lin Yu didn't seem to care at all?

Lin Yu was actually quite clear-headed; he had already sensed something was wrong with the system. This was a world of magic, and you want me to cultivate immortality? Could I even do that? I couldn't cultivate at all.

There isn't even a trace of spiritual energy, how can I cultivate?

The system still wants him to do tasks? The problem is, they're completely worthless.

So when Lin Yu heard the system's voice, he asked in his mind with little interest, "Chaotic Dao Body? What are the benefits?"

The system gritted its teeth and said, "That's the Chaos Dao Body. Legend has it that chaos existed before heaven, so the Chaos Dao Body is uniquely blessed and favored by the Heavenly Dao. Moreover, once the Chaos Dao Body is fully mastered, not only will one's Dao techniques be naturally perfected, but one will also be impervious to all laws. One can even master all laws. You can think of it this way: the magic you've learned is just one of the three thousand Great Daos. Once you fuse with the Chaos Dao Body, learning anything will be twice as effective."

Upon hearing this, Lin Yu immediately sat up and said without hesitation, "Then what are we waiting for? Isn't this my reward? Why hasn't it been fused with me yet?"

Helpless, the system suppressed the urge to swear and asked again, "Does the host wish to fuse with the Chaos Dao Body?"

Lin Yu nodded in agreement: "Integration? Since there are benefits, why didn't you say so earlier? We must integrate."

The next instant, Lin Yu felt a surge of heat suddenly well up inside his body, which quickly spread to every corner of his body and to every cell.

At this very moment, a tremendous change is taking place within Lin Yu's body. Every cell, every inch of his flesh and blood, and even every bone, is undergoing a transformation.

Moreover, the process was quite lengthy, and Lin Yu unknowingly fell back onto the bed, closed his eyes, and drifted off to sleep.

Meanwhile, at Hogwarts.

Although the new school term hasn't started yet, the vast Hogwarts Castle seems incredibly deserted. Apart from a few ghosts wandering around the castle and house-elves in some unknown corner, there are almost no strangers.

However, there are exceptions. For example, Dumbledore, the headmaster, always lived at the school and didn't like to leave even during holidays.

Dumbledore had originally intended to prepare a cup of black tea and leisurely spend the afternoon undisturbed by a group of young wizards.

There was a knock on the office door, and his vice principal, Minerva McGonagall, walked in.

"Albus, you really should see this," Professor McGonagall rushed up to Dumbledore, holding a letter in her hand.

Dumbledore took the letter with surprise. He hadn't read its contents yet, but he was astonished by Professor McGonagall's strong reaction.

It wasn't until Dumbledore finished reading the letter that he seemed to understand why Professor McGonagall was so surprised.

Even he was surprised.

"A child who wasn't recorded at birth? Or rather, a child who shouldn't have existed, or shouldn't have come into being? What's going on?" Dumbledore muttered to himself.

Professor McGonagall sighed. "That's what I wanted to ask too. Hogwarts keeps a record of every wizard born in England and sends them an invitation to study at Hogwarts when they turn eleven. This includes not only children from wizarding families but also young wizards born into Muggle families. But this child... he doesn't belong to us."

The letter belonged to Lin Yu.
