"Are you planning to leave the school tonight?"

Principal Dumbledore looked at Lin Yue in surprise, and Professors McGonagall and Flitwick also looked at her in disbelief.

It was the first time Lin Yue had actively requested to do something other than studying.

However, Professor Flitwick looked at Lin Yue with concern, "Miss Lin Yue, students are not allowed to leave Hogwarts during term time, especially at night. This poses certain safety risks for you."

Lin Yue nodded, her expression remarkably calm. "I understand Professor Flitwick's concerns for me, and I appreciate the professor's care. However, based on my calculations, there are not many people in the magical world who can pose a threat to me right now."

Her sharp mind quickly listed three names, "And those people are either unable to act against me or cannot come before me to do so."

"Miss Lin Yue, have you ever heard the saying from your Eastern culture, A spear in daylight is easy to dodge, an arrow in dark is difficult to defend against.?"

Professor Snape's voice was deep, and his dark, hollow eyes were fixed on Lin Yue.

"Under absolute strength, all conspiracies will come to nothing."

Several professors felt a bit choked, and Principal Dumbledore chuckled twice, looking at Lin Yue with a smile on his face.

"Then, Miss Lin Yue, could you tell us why you must go out tonight?"

"Of course, Principal Dumbledore."

Lin Yue nodded without any change in her expression and confidently stated what she was going to do.

"I am going to create a supply system tonight that can replace all current market supply chains in the magical world."

"Why do you want to do that?" Professor McGonagall frowned, looking at Lin Yue in confusion.

"To push pure-blood families out of the magical market."

Lin Yue was unreserved about her intentions, even with Professor Snape, the head of Slytherin House, sitting right next to her.

"It seems I really shouldn't be here listening to this."

Professor Snape's hollow gaze slowly faded, replaced by a heavy scrutiny and examination.

"When pure-blood families realize what they should do and completely abandon the ideology of blood purity, they can re-enter the market."

Lin Yue's voice did not change under Professor Snape's gaze; she remained calm and stern, like an unchanging glacier.

"If this does not happen, the magical world and the Muggle world will never have a chance to merge."

"According to projections, with the advancement of Muggle technology, if the magical world cannot integrate with it, war will be inevitable."

"The magical world has less than a forty percent chance of winning, and at the same time, war will accelerate resource depletion. Coupled with the lack of change in the world, there is a high probability that this world will repeat the mistakes of my original world."

After laying out her deductions, Lin Yue fixed her gaze on Professor Dumbledore.

"Can I go out tonight, Professor Dumbledore?"

Dumbledore raised his hand to rub his brow; at that moment, he was only thinking about how to deal with Voldemort, vaguely considering the possible clash between the magical world and the Muggle world in the future.

But he certainly did not think as far ahead as Lin Yue, nor did he consider as much.

According to Lin Yue's calculations, the transformation of the magical world was imminent, and even the transformation of the entire human world, including the Muggle world, needed to be put on the agenda.

"Miss Lin Yue, how can we believe that the future you envision will be better?"

Professor Snape pondered for a moment, elongating his tone as he slowly inquired.

"Because according to the data calculations, no matter how bad the future is, it cannot be worse than the outcome of my original world; that is an inevitable result."

After saying this, she paused for two seconds, glancing back at Hermione, who was sitting at the Ravenclaw long table, seemingly nervously staring at the faculty seats.

With a tone that was stiff yet somewhat resolute, she said, "And I will absolutely not let the future of this world head in the direction of my original world, nor will Hermione, nor will the Ravenclaws."

"A bold idea, Miss Lin Yue. We old folks are indeed getting old; the future of the world belongs to you."

Principal Dumbledore chuckled lightly a couple of times and nodded in agreement, "Go ahead, your strength is indeed enough to reassure us, but do remember to pay attention to safety."

"Of course, I won't let myself create any safety hazards that would cause me to miss classes," Lin Yue said matter-of-factly.

Hearing her mention study-related topics again, the professors present couldn't help but twitch their lips simultaneously.

Truly, Lin Yue is remarkable; just moments ago she spoke of things that could change the magical world and even the world itself, and now she can pivot the conversation back to studies.

"I will help you contact a few other potion masters. What kind of payment can you offer them?" Professor Snape interlocked his fingers and rested his chin on them, meeting Lin Yue's cold gaze.

Enjoying this book? Seek out the original to ensure the author gets credit.

"On your own, you won't be able to persuade them in a short time."

"One million Galleons per person per year. I need each potion master to be able to mass-produce all potions except for advanced ones."

"In other words," Lin Yue's voice still carried a hint of mechanical tone, "I need them to teach other staff members how to make those potions and ensure the quality meets the standards."

Professor Snape felt his eyebrows twitch violently. If anyone else had said this to him, he would have immediately cast a Sectumsempra at the person.

What level of expertise does a Master Potion Maker have? You want them to teach others how to brew potions, and besides advanced potions, do you expect the staff to be able to make all other potions to a quality standard?!

Does the person who said this not realize how scarce potions are in the magical world right now? Sure, anyone can brew simple potions; schools teach that.

But slightly more complex potions can fetch a high price. Otherwise, St. Mungo's Hospital for Magical Maladies and Injuries wouldn't have such high revenue.

Not to mention that some people are as clueless as trolls, practically with their heads filled with weeds—can they really be taught?

However if we consider Lin Yue's premise, Professor Snape thought, this might not be impossible. A group of the most capable potion makers in the current situation should have no problem teaching others how to brew potions.

After all, he is already teaching a bunch of little trolls how to brew potions; if he can teach them, they should be able to learn too.

Moreover... Professor Snape slowly shifted his gaze to Principal Dumbledore, and it seemed that his salary for the entire year was not even as high as that.

Principal Dumbledore turned to look at Professor Snape after noticing his gaze, blinking his "innocent" blue eyes.

It was no use looking at him; the funding for Hogwarts came from the school board, and he couldn't be as generous as Lin Yue. Unless Hogwarts planned to operate for just this year and then stop.

"Hmph."

With a cold snort, Professor Snape turned back to Lin Yue and nodded, "Deal, Miss Lin Yue."

"Thank you for your help, Professor Snape."

Lin Yue nodded calmly and turned to walk down from the teacher's podium.

Would a potions master lose money giving one million Galleons a year?

That question was certainly valid in the early stages, and a line graph quickly appeared in Lin Yue's mind.

In the beginning, the curve for potions indeed showed a deficit, but with the rise of another variable—the degree of integration between the magical world and the Muggle world—this would drive the second variable, the demand for potions, to increase.

With both variables growing positively, the income in the field of potions would also rise rapidly, reaching an unprecedented height.

At that time, the profits generated could even be enough for the investor Lin Yue to become one of the world's wealthiest individuals.

Although she was already considered one.

But who would complain about having too much money? Although Lin Yue still had no extra feelings about money at the moment.

But after all, there was Hermione. Lin Yue walked back to Hermione and looked at her intently.

She needed to earn more money; she firmly thought about this in her mind, so she could provide Hermione with a better life.

Even if she didn't know why she thought this way, she would go ahead and do it without hesitation.

"Are you going to be busy?"

Hermione stood up and helped Lin Yue tidy her hair by her ear.

"Yes."

Lin Yue nodded with a detached expression, but upon closer inspection, one could still see a hint of redness at her ears.

"Be careful with everything, remember to come back tomorrow, don’t make me worry."

Hermione gently wrapped her arms around Lin Yue's waist, burying her face in her chest, listening to her strong heartbeat.

Lin Yue raised her arms to hug Hermione back and replied earnestly,

"Don’t worry, I will definitely be back tomorrow morning. I won’t let these things delay my classes."

"Pfft," Hermione let go of Lin Yue, looking at her with a mix of amusement and exasperation, and reached out to poke her little nose, "You really can’t stop talking about studying, can you? You never forget about studying."

"Studying is a student's duty."

Lin Yue instinctively blurted out, and after pausing for a few seconds, she added,

"But it’s not the only thing for a student."

This was a lesson she had learned at Hogwarts from Hermione, the professors, and her classmates.

"Well said," Hermione stood on her tiptoes and gently kissed Lin Yue's rosy cheek, "Go on."

Lin Yue lowered her gaze, nodded slightly with her head down, and quickly turned to walk out of the hall.

Once outside, Lin Yue raised her hand to touch the spot on her cheek where Hermione had kissed her, and a smile unconsciously appeared at the corner of her mouth.

She strode towards the outside of Hogwarts Castle and paused in an open area outside the castle.

Meanwhile, Professor McGonagall in the hall seemed to remember something and turned to look at Professor Dumbledore.

"Did we forget to ask how Lin Yue plans to get to the place she wants to go from Hogwarts?"

Dumbledore's hand, which was stroking his beard, paused slightly before resuming its motion as if it had never stopped.

"That's alright, Miss Lin Yue will surely have her own way."

"Alright." Professor McGonagall nodded reluctantly, not wanting to dwell on it any longer.

At the same time, in the open area outside the castle, Lin Yue gently waved her wand, casting a silent levitation charm.

Her whole body slowly lifted off the ground and rose into the air. In the next moment, she swiftly floated away into the distance, with all the howling winds directed at her being firmly blocked by the Shield Charm.

That night, Lin Yue went to Diagon Alley, visited Gringotts, and even went to the Muggle world government department.

Although it was nighttime, money can make things happen, and with Lin Yue's strength, the goblins at Gringotts didn't dare to say much.

Without further ado, they sold her the idle land that belonged to her, ensuring that Lin Yue's land transactions had no involvement with the Ministry of Magic.

Next, she targeted the businesses in Diagon Alley, effectively hollowing out the downstream of the supply chain.

After all, these businesses had not signed long-term contracts with pure-blood families, and they had previously witnessed Lin Yue dealing with the Malfoy father and son, as well as her polite compensation to the businesses affected by that incident.

They chose to cooperate with her without hesitation, as compared to pure-blood families, this young girl’s character was certainly more trustworthy.

Not to mention, this young girl even took the initiative to offer them benefits, allowing them to earn more.

As for the Muggle world government department, although Lin Yue was a minor, with that card of hers, buying land and shops was not impossible.

Money can always open many doors.

After purchasing those idle lands, Lin Yue went directly to Chinatown in London, where she received a warm welcome from many people.

This enthusiasm immediately increased when they heard about the dozens of major projects Lin Yue brought with her.

"Twenty factories, fifty shops, to be built and decorated within a month, with guaranteed quality and quantity, is that doable?"

Lin Yue looked at the dozen or so qualified Chinese construction teams in front of her and calmly stated her needs.

"No problem! Leave it to us!"

The heads of the construction teams, smiling broadly, patted their chests in assurance. After collecting Lin Yue's payment, they immediately set off for the site to prepare for work overnight.

Such a large order was not something that came by often, so they had to get started right away!

After everything was settled, it was already 1 AM. Lin Yue waved her wand and took to the air, returning to Hogwarts as quickly as possible.

If her estimation was correct, Hermione was likely...

Gently opening the door to the Ravenclaw common room, Lin Yue was not surprised to see Hermione sitting on the sofa, sound asleep with a book in her hands.

Walking over quietly, Lin Yue carefully picked Hermione up, who was indeed waiting for her return.

Looking down at Hermione's peaceful sleeping face, a hint of warmth appeared in Lin Yue's otherwise indifferent eyes.

Steadily carrying Hermione back to the dormitory, Lin Yue gently placed her on the bed.

She knelt down to help her take off her shoes, socks, and wizarding robe, then carefully tucked her into the blanket.

After making sure Hermione was snug under the covers, Lin Yue took a deep look at her before pulling down the bed curtain to block out the light from outside.

After washing up in the bathroom as quickly as possible for two and a half minutes, Lin Yue came out, used a spell to dry her hair, and lay down on the bed.

Closing her eyes, she fell into a deep sleep the next second.

Ensuring six hours of sleep... she needed to sleep until 7:30 AM tomorrow... this was the last thought in Lin Yue's mind before she drifted off.

On another bed, Hermione seemed to sense something, murmuring as she snuggled into the soft bedding beneath her, her face adorned with a radiant smile.
