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

Although there was a slight unpleasantness because of Snape, overall, the hot pot meal was quite enjoyable.

Moreover, Lin Yu didn't hide anything good; instead, he used a 100,000-year-old medicinal herb as the base of the pot.

After the two professors finished eating the hot pot, they felt warm all over, as if they had eaten from a stove.

No matter how cold it was outside, they didn't feel cold at all. Their hands and feet were warm, and their blood flowed faster, as if their bodies had become ten years younger.

A medicine aged for 100,000 years is comparable to a divine medicine.

It is no exaggeration to say that even if a little bit of medicine powder cannot bring the dead back to life or heal bones, it still has unimaginable benefits.

If Lin Yu could use this powerful medicine to prolong the lives of Dumbledore and Professor McGonagall over a long period of time, they might even be able to rejuvenate and live a second life.

It means they can go back to the age of seventeen, live their lives again, and retain all the experience and strength they have accumulated throughout their lives.

It can be seen.

After lunch, Hermione, ever the domestic goddess, began packing.

Lin Yu was in charge of cooking, and she was in charge of cleaning up; they were a perfect example of a wife taking the lead and a husband following suit.

Dumbledore and Professor McGonagall sat to the side, watching with smiles on their faces, admiring the young couple.

After everything was packed, Hermione came to Lin Yu's side, and the two of them said goodbye to the two old professors: "Then we'll head back now."

The two elderly people nodded with smiles.

How wonderful! It's so good to be young and still be able to experience the taste of love.

This is youth.

After leaving the principal's office, Lin Yu and Hermione walked down the corridor on the eighth floor, discussing what to do that afternoon.

"Would you like to come to the library with me? Or perhaps we could go to the Room of Requirement to cultivate? You've just successfully established your foundation, so why don't you rest for a few days?" Hermione suggested.

She felt that since she had just established her foundation, there was no need to rush to improve her cultivation level, lest her realm become unstable.

Lin Yu thought for a moment and said, "Tomorrow is Saturday, and it's the first Quidditch match. Let's get some rest today."

They have indeed been very diligent and busy lately.

During the day, they have to attend classes, and at night they have to practice meditation. Even on Saturdays and Sundays, they are mostly busy completing tasks to earn rewards before returning to their practice.

If it weren't for the lack of resources, they would have already established their foundations.

With the Quidditch match just around the corner, Lin Yu wanted to take a break.

And so, the two of them walked hand in hand to the library located on the second floor of the castle.

There are thousands of bookshelves here, containing at least tens of thousands of books, with hundreds of narrow aisles between them.

The librarian was Mrs. Irma Pines.

Mrs. Pince was a thin, elderly woman who looked like a malnourished vulture.

Although it's not nice to describe a witch like that, she was strict and rule-abiding. She almost always stayed in the library, guarding the books she cherished and keeping an eye on the students who used them.

Moreover, some people were whispering that Mrs. Pince and the caretaker Filch had an unusual relationship.

Because many students dislike Filch, they inevitably talk badly about him behind his back.

But if Mrs. Pince heard anyone speaking ill of Filch in front of her, without exception, they would be kicked out by Mrs. Pince.

This inevitably leads people to overthink things.

Hermione really loves reading, and she hasn't had time to come here for leisure lately. This time, she picked up several books and finished reading them very quickly.

Hermione discovered that her memory was now excellent; she could read almost ten lines at a glance and had a photographic memory.

"Lin Yu, is this also a benefit of cultivation?" Hermione asked Lin Yu in a low voice.

Lin Yu nodded: "Not only that, there are many other benefits as well."

As their cultivation level and spiritual awareness improved, they naturally began to transcend the ordinary and enter sainthood.

After the initial surprise, Hermione suddenly became somewhat bored.

She simply enjoys the process of reading, rather than the result of rote memorization.

So Hermione stopped skimming and started reading a book word by word.

Lin Yu shook his head with amusement and sat down to keep him company silently.

Suddenly, Lin Yu thought of something, leaned close to Hermione's ear, and whispered, "Do you think I could make a fortune if I wrote a novel?"

For example, could we simply copy those fantasy novels from our past lives and make them a huge hit in the magical world?

There are genres like the annulment of an engagement, the return of the Dragon King, and the son-in-law/son-in-law relationship.

Fortune changes every thirty years; never underestimate a young person's potential.

At that time, wouldn't he be able to lead a new generation of trends?

It sparked a new trend.

By then, young wizards will probably all consider flying on swords as fashionable, right?

And of course, there's also the ability to transform fighting spirit into a horse?

Hermione gave him a playful glare and said, "You should be thinking about how to sell the Marrow Cleansing Pill. Selling just one will make you a fortune."

Lin Yu scratched his head. The price of a thousand Galleons was probably too expensive. Apart from Draco, who was a sucker, no one else had asked about it.

How about we lower the price a bit? For example, 999 Galleons for one Marrow Cleansing Pill?

It's probably no different from not lowering the price at all. People who can come up with 999 Galleons, would they care about just one Galleon?

Before they knew it, Lin Yu and Hermione had been sitting in the library until evening.

Because it was in the library, and Mrs. Pince was watching very closely.

Lin Yu and Hermione behaved themselves without making any sudden movements.

But when the time came, Mrs. Pince still kicked the two of them out.

"I need to eat too," Mrs. Pince said irritably.

She has a really bad temper.

As Lin Yu and Hermione were leaving, Lin Yu couldn't help but say, "If I ever become the principal, I will definitely address the problem of these incompetent teachers."

Hermione shook her head with amusement, reminding her, "Didn't you still want to be Minister for Magic?"

"You can be the minister, and I'll be the principal. Or I can be the minister, and you can be the principal?" Lin Yu naturally took Hermione's small hand, and the two intertwined their fingers, gazing at each other with deep affection.

However, the content of their conversation was quite audacious, as if they could become either Minister of Magic or Headmaster of Hogwarts if they wanted to.

In reality, only they themselves know that even without reaching adulthood, their current cultivation level is already powerful enough.

No one in this world knows what a cultivator represents, let alone how powerful a Foundation Establishment stage cultivation is.

However, sooner or later, they will bring a small shock to the wizards of the magical world.

When Hermione and Lin Yu arrived at the restaurant hand in hand, Harry and Ron sat opposite them, frantically giving them meaningful glances.

Lin Yu looked puzzled: "Why can't we say this later? Why do you have to give me these winks now? The thing is, I don't understand them either."

They can't possibly assume they truly understand, can they?

Harry cautiously looked around and, seeing that there were too many people nearby, had no choice but to endure it.

After finishing dinner, the four of them walked out of the restaurant together in tacit agreement, and waited until they reached a corner.

Harry couldn't hold back any longer and said urgently, "I've discovered Snape's secret."
