A day at Hogwarts.

Chapter 680 This business is good
Charles returned to the entrance to the Gryffindor common room and stood before the enormous portrait of the Fat Lady, who was feigning sleep in the painting.

Just as he was about to give the password for the day, an extremely bold and tech-savvy idea suddenly struck him like lightning.

Could you find a way to extract the source code of the Fat Lady's GIF oil painting and secretly set a backdoor password that only you know about?
From a technical standpoint, it doesn't seem that difficult, given his in-depth research into the magical system of Hogwarts Castle itself.

Moreover, and most importantly, Charles has already learned and mastered the unique magical communication protocol used to transmit messages between all the paintings in Hogwarts Castle through the Painting Society.

This means that he could even have Hatsune Miku in the large recipe model remotely connect to the fat lady's place via the network of the portrait room to visit and perform some operations.

Given this technological background, he could remotely modify the fat lady's source code without anyone noticing, and what he could do would be far more than just adding a back password.

The more I think about it, the more feasible it seems. Once it's done, I won't have to rack my brains to remember so many troublesome and frequently changing passwords anymore. It's a godsend for lazy people.

I don't know if this violates school rules. He's not very familiar with them. I'll ask Hermione another day.

You can see whoever you want.

Charles was lost in his fantasies about doing something indecent to the portraits of the Fat Lady, his eyes shining as he stared at the portrait of the Fat Lady. Just then, the door behind the portrait opened without warning.

Hermione happened to come out of the common room and looked up to see Charles standing outside the door. His eyes were shining with extreme excitement, like a ruby ​​that had discovered braised pork belly with taro. His gaze was fixed on her.

Startled by the sudden, intense gaze, she instinctively reached for her wand, nearly raising it to strike Charles.

Hermione is a beautiful young woman now, and she's been stared at like that by boys more than once or twice, so she's long since learned to handle it with a calm attitude.

However, now that Charles was looking at her, she immediately and instinctively raised her hand and quickly touched the top of her head.

Preparations are underway for the Halloween Eve dance. Tonight, Fred and George are catching people in the common room to test the transformation potion, and she's worried that she might unknowingly fall for it.

Thankfully, there were no cat ears on her head, which relieved her greatly and calmed her heartbeat a little.

But the next moment, her cheeks flushed bright red as she recalled the incident from years ago, and a surge of anger welled up inside her.

She angrily raised her foot, as if to kick Charles's shin.

Charles reacted quickly, nimbly leaping backward to dodge the powerful attack, then asked her with a bewildered look, "Hey! What did I do to you this time?"

Hermione pouted, her cheeks still flushed, and said angrily, "Who told you to look at me like that, like I'm some kind of magical creature!"

Charles rolled his eyes at her without any politeness and said in a matter-of-fact, slightly disdainful tone, "Who said I was looking at you? I've been looking at you for so many years, and you're still the same. Apart from being a little fatter than before, what earth-shattering changes could you have?"

He deliberately dragged out the intonation of certain keywords.

Hermione took a deep breath, her chest heaving, and realized she really should find an opportunity to learn the three Azkaban Invitation Charms as soon as possible.

Charles wanted to continue teasing, but when he saw Hermione close the door, his brows suddenly furrowed.

He raised his wrist to look at the watch face; the hands showed it was quite late. He then asked Hermione with a puzzled look, "Wait, where are you going all night by yourself?"

He remembered clearly that it wasn't Hermione's turn to patrol tonight, and if she really wanted to cause trouble, she would definitely bring Harry and Ron along, as was her habit.

So going out alone so late at night seemed quite suspicious. Hermione's cheeks flushed slightly again, and she awkwardly turned her head away, avoiding Charles's probing gaze, and mumbled, "It's none of your business. Where I go is my own business."

Charles keenly caught her blush and evasive gaze, and his brows furrowed even more tightly, almost forming a knot.

He asked tentatively, with a hint of disbelief, "Hey... Hermione, you didn't sneak out to go on a date, did you?"

It's not unusual for girls this age to be in love, and Miss Granger is well into her prime.

However, sneaking off on a date late at night is a serious problem. Violating school rules is a minor issue; safety is the real concern!

"None of your business!" Hermione snorted and walked away.

Charles immediately followed, relentlessly asking as they walked, "You're not really going on a date, are you?"

"Tell me the truth, who is it with? Which college? Do I know them? Are they reliable?"

Hermione mistook him for Peeves, snorted, quickened her pace, and said with a hint of defiance, "So what if he is? What's it to you!"

"When I wanted to ask you out, you had already disappeared to some faraway place, and I couldn't find you anywhere!"

Charles believed she was deliberately changing the subject, since everyone knew he was busy during holidays and often not in the UK.

But he still followed up the conversation, asking, "Oh? Where do you want to go with me? Tell me?"

He wanted to see what excuse she could come up with.

Hermione replied somewhat dejectedly, "It's a new amusement park that's only been open for a few years on the east side of Paris."

Charles nodded, understanding. It was the American Giant Rat Amusement Park, which opened in 1992.

Hermione wanted to go there, but the biggest obstacle for her wasn't money, but the Grangers' busy work schedules, making it difficult for them to take her on a trip abroad.

Among her peers at Hogwarts, Charles seemed to be the only person the Grangers could trust to accompany her on such an international trip.

It's simple, Charles understands foreign languages.

“It’s alright, it’s no big deal.” Charles suddenly stroked his chin, thinking as he spoke, “I’ll build one for you, right next to Hogsmeade Village. I’ll build a wizarding playground, I guarantee it’ll be even more fun than the Muggle one. You can just walk a few steps to play after class, how convenient!”

The more he thought about it, the more feasible the idea seemed.

In his opinion, the wizards' entertainment activities were still too scarce. Although the total wizard population was not large, the cost of building and maintaining a magical amusement park could be kept very low by magical means.

If it were opened to wizards worldwide and turned into a tourist attraction, it would seem like a promising business opportunity and could potentially make money.

Hermione was so shocked by his words that her eyes widened and her mouth opened slightly.
