Hogwarts: Lacus doesn't want to be a witch who destroys nations.

"Moonstone powder, dragon's blood, exquisite! Absolutely exquisite! The proportions... my god! The ratio of styrax syrup as a lubricant for the flow of magic, the ratio of Motra rat tentacles and wormwood juice... and the timing of adding this avian snake egg..."

His voice grew increasingly agitated, and he almost spat saliva onto the parchment.

"The heat, the frequency of stirring—every single detail is perfectly executed, logically consistent. It's simply... simply..."

Slughorn abruptly raised his head, looking at Lux as if she were a walking Philosopher's Stone.

Shock, inquiry, disbelief, and a slight dizziness from being overwhelmed by a wealth of knowledge.

"This is simply... groundbreaking!" Slughorn's voice trembled with excitement, his round face flushed red. "A completely new potion system! Built on Dumbledore's research on dragon blood, it uses modern potion materials and theories to solve an ancient problem that has plagued us for centuries: the pain and loss of control during werewolf transformation."

Slughorn was panting heavily, his chest heaving as if he had just run a marathon.

"An ancient recipe?" Slughorn scoffed. "Miss Lux, are you kidding me? Or is this some kind of joke Dumbledore gave you to amuse me with? This recipe, the theories and techniques it references are newer than the cauldron I just bought! I wouldn't even dare say I've fully grasped Dumbledore's research on dragon blood, and now I have a finished recipe right in front of me."

Lux blinked, surprised by Slughorn's strong reaction: "Huh? Is it that new? I didn't know, Professor. I just thought the recipe was written in pretty detail."

"My Merlin, it's so detailed it's like it's holding my hand while I'm making it. There are currently no published papers on using dragon blood as a potion base. Just by making this formula public, it'll be enough to earn a second-class medal from the Order of Merlin."

Slughorn's eyes widened like searchlights. "Child, the only thing you need to tell me now is the origin of this recipe, not nonsense like 'ancient recipe.' This recipe uses a completely new system, which is completely different from ancient potions."

Now it was Lux who was in a dilemma. She couldn't very well say that it was invented by future wizards and then improved by Dumbledore, Snape, and others, so she had no choice but to say shamelessly, "Actually, I saw how difficult the werewolves' lives were during my vacation, so I started researching and made some progress. Maybe Merlin saw that I was beautiful and kind-hearted and helped me out, hahaha..."

During Lux's awkward laughter, Slughorn was the one who couldn't hold back the most.

What does it mean to have results as soon as you start research?

What does it mean that my students' inventions during the holidays have a high chance of being published in top journals?

What does it mean that a student who can't even distinguish the model of a crucible has mastered the forefront of academic research?

"Miss Lux, the most important thing right now is to see if you are a descendant of Merlin. He has been too kind to you." Slughorn was completely absorbed in the fantasy of discovering a potion-making genius, his mind filled with the unparalleled glory and academic status that would come with the successful verification of the potion.

"Listen, Lux, my child! After class, no! Now! Immediately! Come with me to my private potion workshop! We must verify its feasibility immediately! Not a moment can be wasted! If... if this formula is real..."

"This will be one of the greatest breakthroughs in potions this century since Dumbledore discovered the uses of dragon blood, and you, Lady Laksana Crownguard!"

He stared intently at Lux, his excitement causing him to grip her wrist. "Whether you discovered this recipe yourself or obtained it through some more mysterious means, you will leave an indelible mark on this glorious achievement. The Slug Club? Ha! That will be your starting point! The International Potions Association's Lifetime Achievement Award is beckoning you!"

"Professor, please, please let go..." Lux felt like her wrist was about to be broken. "The formula isn't lost! And do we even have the ingredients?"

"Right! Right! Materials!" Slughorn snapped out of his daze, loosened his grip, and slapped his shiny forehead in frustration.

"Look at me, I'm so excited I forgot! And the materials! Dragon blood extract, fresh dragon blood, moonstone powder! These aren't things you can just buy anywhere in Diagon Alley. I need to write to my old friend right now… No, no, I need a more reliable source, Merlin! This takes time! It requires preparation!"

He paced excitedly in his office like a wound-up top, muttering about various ingredients and the names of potion masters, completely abandoning his composed and elegant Slytherin headmaster persona.

Finally, he stopped abruptly in front of Lux, his chubby face showing an unprecedented seriousness and pleading.

"Lux, my dear child!" he said solemnly, "Please keep this recipe safe! Before you have prepared the ingredients, do not show it to anyone except me, not even Dumbledore! You know he's too busy; the concoction of such delicate potions requires absolute focus!"

He rubbed his hands together, his eyes so fervent they could almost set the parchment ablaze.

"Give me three days! No, two days! I will prepare the finest materials and the safest refining environment in my private workshop, which has the most complete equipment in Europe. I want to personally start this potion experiment that could change the history of magic."

He extended his hand in a solemn gesture of invitation, his chubby face etched with the words "academic fanaticism."

"Would you like to be a participant in this historic moment, Miss Lux?"

Lux looked at the Potions professor, who was as excited as a 200-pound child, and knew that things had gone well. A bright smile then spread across her face.

"Of course, Professor! It's my duty, Lux, to contribute to the field of Potions! However..."

Lux pointed to her wrist. "Next time you invite me, could you be a little gentler? I'm afraid my potion stirrer will break before the experiment even starts."

Slughorn paused, then burst into a slightly embarrassed laugh: "Hahaha! My bad, my bad! I got too excited! It's settled then! See you at my workshop in two days!"

He watched Lux's retreating figure as she left the classroom, then lowered his head again, gazing fervently at the recipe, muttering to himself, "A completely new potion-making theory based on dragon blood... Merlin, my name, Horace Slughorn, may truly be inscribed on the monument of potions..."

Lux, on the other hand, felt relieved. After all, as long as the potion could be made, she didn't really care about the authorship of the potion.

Vera is still living in St. Mungo's, and Lux ​​sincerely hopes that the child will suffer less.
