Harry Potter: I Have A mastery System

The bank card was the royalties from the works Carlos had written before, and he did not want to be financially restricted by his family.
After walking out of Gringotts, Carlos came to Madam Malkin's Robe Store, a robe store that appears frequently in the Harry Potter world.
"Ding-a-ling, ding-a-ling." The bell on the door rang loudly.
"Good afternoon, Mrs. Malkin, I am a first-year student at Hogwarts School of Witchcraft and Wizardry," Carlos said softly.
"Oh, hello, young sir, I'm very happy that you chose here. Is this the best wizard robe store in the country?" Mrs. Malkin said with a smile.
"I need a set of new first-grade books [uniforms] and some decent wizard robes," Carlos said with a smile.
"My name is Carlos Lucifer!" Carlos said cautiously.
"You are the legendary Saint Lucifer Carlos who came to study at Hogwarts. I will prepare a well-fitting wizard-specific robe for you."
Carlos nodded lightly, and then followed Mrs. Malkin into the store to measure the appropriate clothing size.
"My dear, do you want a looser fit or a fitted one?" Madam Malkin asked while measuring.
"Well, I want it to be a little looser and a little longer, what do you think?" Carlos said with a chuckle.
"Of course, dear, pick up your robe in three hours." Mrs. Malkin said after the measurement.
"Okay, thank you Madam Malkin, please excuse me."
"It is our honor to serve you. You and Saint Lucifer will eventually become holy."
"Okay." Carlos replied softly, turned around and walked out of Madam Malkin's robe shop.
Carlos first paid attention to Madam Malkin's robe store, which was said to be the best. After making short and fat Madam Malkin, she helped measure the body shape and suggested that he buy other supplies first.
He decided to buy a wand first. Ollivanders was the store with the best reputation in Diagon Alley, but the wand shop was small and shabby. The gold sign on the door had peeled off, and it read: Ollivanders: Since 300 BC A well-made wand made in eighty-two years. In the dusty window, a solitary wand sat on a faded purple cushion.
"Well, this is an old-looking store." Carlos said in his mind.
After Carlos entered the store, there was a jingling bell on the door.
"Good morning." A soft voice said in vain behind Carlos.
Carlos said softly: "Good morning Mr. Ollivander, I need a wand!"
"Well," said Mr. Ollivander, giving him a sharp look.
"Okay, Mr. Carlos Lucifer, come on. Let me take a look." Ollivander took out a long tape measure with silver scales from his pocket.
"Which arm do you use your wand with?"
"I'm right-handed," Carlos said.
"Put your arms up, okay!" He measured Carlos, starting from his shoulders to his fingertips. Ollivander measured it and said, "Every Ollivander wand contains super powerful magical substances, which is its essence, Mr. Carlos. We use unicorn hair and phoenix tail feathers." …"
Carlos wanted to interrupt the old man's soliloquy, but finally gave up. Ollivander must have said the same thing to everyone who entered the store.
After a while, Ollivander finished measuring the data, then walked to the shelves and began to pick up the long boxes on the shelves one by one.
"Okay, let's try this one. It's made of peach wood and dragon. It's nine inches long. It's nice and tough." He handed the wand to Carlos' hand.
"What are you waiting for? Just wave and see." Looking at Carlos who was in a daze, Ollivander prompted.
Immediately, Carlos waved his magic wand, and with a 'bang' sound, the vase facing Carlos exploded, scattering fragments all over the floor.
"No, no, this one definitely won't work." As he said that, Ollivander took the wand from Carlos' hand.
"Here, try again||Try this one, Sakuragi, the god||script of the Oris Demon Snake, nine and a half inches, very suitable for silent casting."
Carlos caught the wand in his hand ||, and as soon as he waved it, Ollivander took the wand out of his hand ||.
"No, this one will definitely not work." He said and went back to the shelf to pick out the wand.
Carlos felt that he was confused. He watched Ollivander stuff wands into his hands one after another, and then took them away again, saying over and over again, this one won't work, and this one won't work either.
Time passed quickly, two hours passed quickly. Julian tried one wand after another, and the wands he tried were piled on the counter, forming a hill.
And Carlos raised his right hand, ready to try a new wand handed to him by Ollivander. It was said to be the horn of a unicorn. The phoenix was reborn from the ashes and left ashes. The heart of the red dragon || was black. Made of unknown crystal, ten inches long.
As soon as he took it, Julian felt a hint of warmth and coolness, and it was comfortable. It was the kind of comfortable warmth and coolness, just like holding a stick made of warm jade in his hand.
The wand in his hand emits a burst of black and white light, and the black and white light gradually forms a pure golden mist.
Just like the original and most authentic divine light.
As if he knew what to do, Carlos waved the wand in || and raised it above his head.
