"Don't worry, we've already handed the letter to the Grangers." Professor McGonagall whispered to Hermione from the platform in Hogmound,

"Oh, thank you, Professor McGonagall." Hemin said excitedly,

"It's nothing, Miss Granger," Professor McGonagall said, and then she admonished, "it's getting colder, and when you get to London, don't take you away, Lawrence will take you to Grimmauld Place with your apparition."

"Okay." Hermione agreed and dragged her luggage on the train, and after a while, the horn sounded, the train moved slowly in the wind and snow, Hermione pulled her luggage into a small box for four people in the shaking carriage, and then closed the door,

Luna put down the "Singing Against the Tune" that she was holding backwards, and helped Hermione pat off the snowflakes on her body, Lawrence sat in the corner of the box, her hands on her backpack, and she was already asleep with her eyes closed.

The train began to accelerate after passing the corner, and then moved towards London at a steady pace, Luna continued to indulge in the "Singing Contrarian" in her hand, and Hermione took out the "Magic Talisman Book" and began to read, the book about ancient magic scripts, which was one of her favorite extracurricular readings in her free time,

The box was quiet, it should be a good place to read, but after reading a few chapters, Hermione felt more and more uneasy, she glanced at Lawrence, who was asleep, and then at Luna, she moved a little uneasily, and then continued to try to turn her attention to the book,

And when she looked away from the book and drifted to Luna again, she saw that Luna put down "Singing and Singing" almost at the same time as her, and their eyes were straight up, which made Hermione startled and quickly moved her gaze back to the book in her hand,

"What's wrong?" Luna asked,

"Uh......" Hermione put down her book a little embarrassed, "No...... Nothing."

"Oh?" Luna didn't ask much and continued to bury her head in reading her magazine, Hermione closed the book, intending to eliminate distractions and take a good rest before arriving in London, but Lawrence's hand on the backpack didn't know when it loosened, and the corner of a red book cover was revealed from the mouth of the backpack, which caught Hermione's attention,

Hermione hesitated for a while, curiosity finally prevailed, she quietly reached out her hand, little by little pulled out the book, she recognized the old book cover written on the runi script - "Extreme Transfiguration", just as she was about to open the book, a strong hand pressed the cover, and then pulled the whole book away, Hermione was so frightened that she didn't dare to move,

"Where are you now?" Lawrence asked in a hoarse voice,

"I...... I guess......" Hermione stammered, glancing at Lawrence with some weakness, only to find that Lawrence didn't pay any attention to her.

"We're about halfway there." Luna's voice came from behind "Singing Against the Tune" at the right time, which made Hermione breathe a sigh of relief,

"Half......" Lawrence muttered to himself, then he tucked the book back into his backpack, didn't say anything more, closed his eyes and went back to sleep,

Hermione also tried to put herself to sleep, but she couldn't succeed, after the train slowly entered the station, she could only open her eyes and get off the train with the crowd,

After saying goodbye to Luna and her father, Hermione followed Lawrence through the checkpoint that limited the number of people who could pass, and after they left the station quickly, they turned a corner and came to a small alley, where they stood facing each other.

"The first transfiguration is usually uncomfortable." Lawrence said to Hermione, who nodded to indicate that he understood, and Lawrence thought for a moment before adding, "Actually, even if you get used to it, you still don't feel comfortable."

"So...... Got your luggage packed? Listen to me count to three," Lawrence carried his luggage in his left hand and placed his right hand on Hermione's shoulder, "one, two, three."

Because the weather was very cold, every pedestrian on the road tried to shrink their bodies and faces into their coats and scarves, and no one paid attention to the small alley, and after a sudden sound, the two figures pulling their luggage disappeared without a trace. (Note 1)

Lawrence returned to the room where he had spent the whole summer, on the fourth floor, and he lay down on the cold mattress, and did not light the fire in the room, but fell into a deep sleep.

The next day, he was woken up by an excited Fred and George, who were clamoring to go to Diagon Alley after breakfast, and Mrs. Weasley was too busy setting up Christmas decorations to take care of the two of them, so after breakfast, the three of them arrived at Diagon Alley with a phantom shapeshift.

"So where do we go first?" Fred and George looked out at the street with great interest,

"There, I remember there were a couple of shops over there that were being rented or sold." George pointed in one direction,

"Hmm...... I can't go with you, I'm going to ask some questions." Lawrence told the twins that Fred and George, although a little confused, parted ways at the street entrance.

Lawrence walked up to Flolin. The small round tables in the open air outside the Fosco ice cream parlor were not taken out, and the windows selling ice cream to the outside were also closed.

Lawrence opened the door, and although it was warm, it was clear that no one would buy ice cream in this weather, not even the owner, Flolin. Mr. Fosco sat behind the counter and snooze,

"Mr. Fosco?" Lawrence screamed tentatively, and after a few more shouts, Mr. Fosco finally woke up,

"Ah, Mr. Rovande," greeted Mr. Fosco in a friendly manner, "what do you need?"

"I'm sorry, sir, I'm not here to buy ice cream." Lawrence said apologetically,

"Ah, yes, not much is going to buy ice cream at this time, is it?" Mr. Focos sighed, "I'm really looking forward to summer, it's always full of people inside and outside the store at that time."

"So, what are you here for, Mr. Rovande?" Mr. Focos asked with a kind smile,

"I've heard you're well aware of the message of ancient magic." Lawrence explained that Mr. Foucers was not surprised at all, but showed a look of surprise,

"Of course, people come to me at this time of year, usually to ask for items or information about ancient magic." Mr. Focos smiled self-deprecatingly,

"And what do you want to ask?" Mr. Focos glanced at Lawrence's backpack and seemed expecting something from Lawrence to take out of it,

"It's this thing." Lawrence took out from his pocket the gold pocket watch he had received from the Ravander family on his birthday,

"Aha," Mr. Focos smiled as he reached out and picked up the pocket watch, looking at the old tree and rabbit carved into the case.

"I remember correctly, you're from a Muggle family, right?" Monsieur Foucaus affirmed that he did not open the case, but touched the old golden tree engraved on the case, and there was a notch on the trunk near the root.

"Have you heard the story of 'Babbitty the Rabbit and His Croaking Stump'?" Mr. Foucaus asked,

"The story in 'The Tales of the Poet Bean', right?" Lawrence replied, and Mr. Focos nodded, and he looked at Lawrence for a moment, then smiled,

"How did you get this pocket watch?" Mr. Foucaus asked,

「…… My Muggle father, on my eighteenth birthday." Lawrence replied,

"The gift of adulthood is a watch, a tradition of some magical families." Mr. Focos said,

"But I'll be an adult at seventeen." Lawrence said,

"Muggles are eighteen years old." Mr. Focos said softly,

"Babbitty the Rabbit is widely believed to be named after a French witch Lisette. Morality. The story of Lapan as the archetype," Mr. Focos continued, "I have reservations about it, but there is no doubt that this pocket watch is a magical creation close to that era."

Mr. Foucus followed the bracelet and picked up the spring at the end of the bracelet, it was an axe-shaped clockwork, he pressed the axe into the notch on the trunk of the old tree, the picture on the case changed, the golden old tree fell, the rabbit no longer hid, but took out a wand and lit the fallen old tree, and a statue was erected from the stump of the old tree, and when Mr. Focos picked up the axe-shaped spring from the notch, the picture of the case changed back to the original,

"Many Muggle-born wizards are surprised to find that their ancestors had wizards when they go back to their family's ancestral tree, and that's nothing new," Mr. Focos said, and he asked with a smile, "But are you still not going to tell me what you are here for?"

Lawrence didn't speak,

"You certainly didn't come to me for this pocket watch," Mr. Foucers laughed and pointed at Lawrence, "you've already discovered the secret of this watch."

"You're like those who aren't quite sure of my abilities, and you'll come to me with some special gadgets first, hoping you're satisfied with my answer," said Mr. Focos, rubbing his hands, "Now, are you going to tell me your true purpose?"

Lawrence nodded slowly, and then he took out a crudely wrapped crown from his backpack that looked like a semi-curved crown from the outside.

Lawrence opened the wrapper, it was a crown of gemstones that had faded a little because of rust, the whole crown was in the shape of an eagle, its body was a beautiful gem, and its wings were bent into a graceful arc to form this crown,

"Merlin...... It's ......" Mr. Focos gasped, carefully caressing the crown along the curve of the eagle's wings, and looked closely at the Ravenclaw aphorism engraved on the base of the crown—that infinite wisdom is the greatest treasure of mankind.

"I want to ask you, is this the Ravenclaw crown that has been rumored to have been lost for centuries?" Lawrence asked,

Under the light of the fire in the store, the jewels of the crown reflect the beautiful brilliance, and the rusty and faded crown seems to have become as shiny as new.
