I'm the king of the roll at Hogwarts

Chapter 2: Choosing a wand is like courting a girl
When he was about to retract the system panel, Louis happened to see through the translucent light screen that the silver-gray cat swooped down and gracefully jumped through the window onto his desk.

"You are so awesome." Louis pinched the cat's left front paw and made a handshake gesture: "You are the big shot."

When he got closer, he found that the cat's face had patterns like glasses. Louis just felt familiar, but he couldn't figure out why he was familiar.

He held the cat's head with his hands, and seemed to think that the cat's head was not round enough, so he kept rubbing it. The tabby cat was shocked, the pupils of her eyes were dilated to the extreme, her mouth was slightly open, and she looked confused. She never dreamed that the little gentleman in front of her would dare to rub a cat of unknown origin.

Keep spinning until a sound is heard, and the achievement frame appears before your eyes.

Ah meow, Ah meow, good boy! (Glorious deeds)
Achievement Description: Interact with Professor McGonagall in cat form
Achievement Reward: Transfiguration Talent +1
"Ah this..." Louis was confused. How could he catch the professor when he picked any cat?
He dared to swear to the lamp that he had never intended to attack Professor McGonagall, it was just because he loved cats too much.

Taking advantage of Louis's daze, Professor McGonagall came to her senses, escaped from Louis' clutches with a somersault, stood up in his dull gaze, and quickly turned into an old cat-faced...old cat girl.

Professor McGonagall was not wearing a hat, and her black hair was neatly tied up behind her head. She wore a pair of very old-fashioned square-framed glasses. After all, she was the head of the school, and her eyes were a little stern.

"Ma'am, I...uh..." Louis didn't quite know what to say.

"I understand your surprise, Mr. Mountbatten." Professor McGonagall tidied her appearance and pursed her thin lips and continued, "I hope you won't blame me for trespassing into your home. I am the deputy headmaster of Hogwarts and the professor of Transfiguration, Minerva McGonagall."

"Well, that won't happen." Louis held out his little hand: "I'm Louis Mountbatten, it's an honor to meet you, Professor McGonagall."

As a gentleman among gentlemen, Louis's etiquette is impeccable. Coupled with his cuteness, Professor McGonagall's initial displeasure instantly disappeared.

Who would get angry with a cute and handsome boy?
A gentleman, of noble birth, and handsome, Professor McGonagall simply couldn't think of a reason to dislike him.

It's much taller than the arrogant little dragon of the Malfoy family. Professor McGonagall doesn't mind chatting and laughing with the little guy.

"I think you have probably received our letter." Professor McGonagall pointed to the letter that had just been delivered: "Mr. Mountbatten, you are a natural wizard, did you know that?"

"I just found out about this too." Louis smiled politely and moved a stool for Professor McGonagall.

"Thank you." Professor McGonagall sat down and continued, "Hogwarts will send school staff to some Muggle families to guide them to buy items for school in Diagon Alley."

She paused and continued, "Since your current situation is rather special, I will guide you to come into contact with the magical world."

"Professor, what are Muggles?" Louis looked so cute and his acting skills were comparable to that of an Oscar winner.

"Poor child." Professor McGonagall stroked Louis' head lovingly and explained to him, "Muggle is our name for ordinary people who don't have magic."

"Then... Professor, can you tell me stories about the magical world?"

"I'm afraid that won't work, kid." Professor McGonagall touched his head. It turned out that his soft hair felt really good.

"We're a little late. If you agree to enter Hogwarts, I'll take you to Diagon Alley to buy some things."

"I have no objection, Professor." Louis said with a smile on his face: "If we are leaving soon, please allow me to ask the butler to prepare the car first."

"No need, child, please put your hand over here."

Louis stretched out his hand as he was told. After a dizzy spell, Louis found himself in a noisy and dirty bar.

The expected motion sickness and nausea did not appear. Louis was still wondering if there was something wrong with the record in the book when he heard Professor McGonagall's praise.

"You are in very good shape, Mr. Mountbatten. Generally speaking, a young wizard of your age would feel uncomfortable for a while after being transported by Apparition."

"Thank you, Professor." Louis looked up gracefully and nodded to Professor McGonagall.

This child... Professor McGonagall thought to herself, and involuntarily smoothed Louis's soft hair again.

After greeting the bar owner, Professor McGonagall led Louis to a wall. She took out her wand, pointed at the trash can as if it were a blackboard, and said, "Mr. Mountbatten, remember this trash can. Count three on top of it and two across it - like this."

She gestured, tapping three times gently on the brick where the wand rested: "Tap three times gently, and changes will occur."

As Professor McGonagall finished speaking, the bricks began to shake continuously and retreated one by one, forming a small hole. The hole became bigger and bigger, and soon, a bright passage was formed in front of them.

Sunlight streamed in through the open passage, illuminating the originally dim bar.

"Cool." Louis exclaimed sincerely.

Diagon Alley was very chaotic, a bit like the vegetable market in his previous life. The road for people to walk on was very narrow, and on both sides were various stalls set up by wizards. Some wizards walked and stopped, picked and chose from the stalls and asked questions. Louis' DNA moved all of a sudden.

"Moonlight grass, fresh moonlight grass, top-quality moonlight grass, three Galleons per plant!"

"Phoenix Tears! Top-grade Phoenix Tears! Plenty of magic power, the best choice for advanced potions, selling for 68 Galleons!"

"Lapis lazuli, cat's eye, magic potion, let you have more abundant and surging magic power, everything is for sale, please come and take a look!"

Louis' first goal was to exchange for some gold galleons.

But...the embarrassing thing was that he left in a hurry and didn't bring any money with him, only the checkbook in his pocket.

Louis turned to look at Professor McGonagall and said dryly, "Professor, it seems that we were in a hurry when we went out. I only brought a checkbook with me."

"Oh, it doesn't matter. Gringotts has a wide range of business, and Muggles' checks can also be cashed in gold Galleons."

Professor McGonagall said, taking his hand and walking towards Gringotts.

According to Louis's visual observation, Gringotts should be the neatest building in this alley. Passing through the bronze door, Louis couldn't help but focus his eyes on the dwarfs with long arms and legs - he had never seen such intelligent creatures before, at least never with his own eyes.

"It's a goblin, a staff member of Gringotts." Professor McGonagall explained to Louis in a low voice.

She was very satisfied. Louis's look was only slightly surprised and then he withdrew. He did not stare at her rudely like other Muggle children.

The gatekeeper fairy bowed to the two of them, and then a second door appeared in front of them. Unlike the previous one, it was silver and had some words engraved on it.

Louis didn't bother to take a closer look and just followed Professor McGonagall inside.

Two goblins - probably lobby managers - bowed to them and led them into a marble hall.

The goblins were doing all kinds of things, weighing gems and gold, taking people in and out, and signing. Professor McGonagall found an empty window and went over to ask, "Hello, we need to put some things into Albus Dumbledore's vault."

"Have you got his key, ma'am?"

"Yes, I brought it." Professor McGonagall took out a bronze key from somewhere and handed something wrapped in a black bag to the goblin.

The fairy took it, took a quick look, nodded and said, "No problem, just leave it to us."

"Sir, what is the exchange rate between pounds and galleons?"

Louis asked the goblin.

"1:5, but the annual quota for each student from the Muggle world is only one thousand, dear sir."

"Do you accept the check?"

"OK."

Louis quickly took out his checkbook and wrote a check for one thousand pounds, tore it off and held it between his fingers, and said with a smile: "I want to change it for two hundred Galleons."

After exchanging Galleons, the first thing to do is to buy a wand.

As the saying goes, the wand is a wizard's second life. Just for this proverb, you should be the first one to buy a wand, right?

Professor McGonagall was already familiar with the roads in Diagon Alley. She took Louis through many paths and finally found the wand shop that looked extremely corroded by time.

A solitary wand sat on a faded purple cushion in the window, and the peeling gold lettering on the door read: "Olivanders, Makers of Fine Wands since 382 B.C."

The shop was very small, with nothing but a bench, and thousands of narrow boxes containing wands were almost stacked to the ceiling. Louis finally got in and saw Ollivander dozing on the counter.

"Hello, hello?" Louis greeted politely.

"Hmm?" Ollivander pulled his head out of his arms, the red marks on his face clearly visible. He shook his head "dumbly" to try to wake up, tried to focus his eyes, and finally saw the appearance of the person coming clearly.

"Professor McGonagall? Oh, hello. I'm sure you're here to bring the Muggle new students to buy wands?"

"Yes." Professor McGonagall patted Louis's head, which was in his good hands, and motioned him to go forward.

"Can you tell me your name, kid?" Ollivander went on to explain, "I'm sorry, wizards who buy wands from me need to be registered with the Ministry of Magic."

"My name is Louis Mountbatten, sir." Louis introduced himself politely.

"Ah...Mr. Mountbatten." Ollivander's eyes flashed with reminiscence: "Excuse me, is David Mountbatten your..."

"My father, sir," Louis replied politely.

"Oh, yes." Ollivander chuckled, "You look more like your mother - ah, Eastern names are really difficult to pronounce, I still prefer to call her Emma... I remember her, she was a very kind Eastern Qigong practitioner."

"I'm sorry, I'm old and I like to talk about the past." Ollivander looked at Louis who was a little depressed and said suddenly, "Mr. Mountbatten, which arm do you usually use?"

"Left hand, sir." Louis held his arm up for Ollivander to measure.

Ollivander took out a measuring tape and threw it into the air, then slowly brought it in front of Louis. He first measured the size, from arm to forearm, from height to head circumference, which made people wonder whether his shop sold wands or clothes.

"Please be patient, Mr. Mountbatten. The wands I sell here are all unique, so the procedures will naturally be more complicated."

Ollivander saw the confusion in Louis' eyes and explained to him carefully: "Only with accurate physical data can we choose the wand that best suits you...Okay, you can come over now."

The measuring tape slowly returned to Ollivander's hand, and Louis followed the measuring tape to the counter. Ollivander had already pulled out a wand from behind: "In order to match your physical data, I already have some backup options, I hope they can meet your expectations... Here, try this one, beech, nine and three-quarters inches, unicorn hair wand core."

Louis took the wand, and the tip of the wand instantly flashed with brilliant light, and the entire wand shook rapidly. I don't know if it's an illusion, but Louis feels that this wand... is a little pleasant?
"Ha, this is the first time I've seen a little wizard who is so perfectly matched with his first wand." Ollivander seemed to have discovered a new world: "Mr. Louis, it seems that this wand is very suitable for you. Let me tell you, the complicated measurement method is a bit laborious, but it is just to help you quickly find a wand that suits you... Just like pursuing a girl, you don't think that all girls will fall in love with you, right? Now, try injecting a little magic power into the wand, just a little bit."

Louis followed his instructions and input a little magic power into the wand.

Who knew that it would be fine if I didn't input it. As soon as I input the magic wand, a hemispherical glow composed of golden magic power quickly expanded and swept across the entire store.

"Clatter..." The boxes containing the wands were opened one after another, and the wands crowded around Louis, one after another, trying to get as close to him as possible, as if wanting him to try themselves.

"Is this what you call complicated?" Louis looked through the gaps between the wands at Ollivander, who looked stunned and surprised. "I see everyone likes me?"
