"So, let's head to Diagon Alley. Mr. Sean Lim needs to buy some essential supplies for school there. Professor Snape (who seemed to grit his teeth) said.

Diagon Alley!

The famous Diagon Alley!

Sean Lin, no, Lin Xiaoan's eyes lit up: "Professor Snape, please wait!" ”

After saying that, Lin Xiaoan hurriedly dragged Mr. Housekeeper's hand and ran upstairs, and after a little more than a minute, the two of them each carried two (a total of four) super large suitcases, and hurriedly ran back - of course, it was Lin Xiaoan who hurriedly ran back, and Mr. Housekeeper followed behind and walked downstairs slowly.

……

"Bang!"

There was a dull sound when the suitcase was placed on the ground, and it was clearly full of things.

"No, no, no! I know school hasn't started yet! It's not luggage! Lin Xiaoan frowned when he saw Professor Snape, and explained in a loud voice.

"Huh"......

Lin Xiaoan unzipped one of the suitcases, and under the illumination of the bright crystal chandelier, the objects in the suitcase reflected a dazzling golden light, unscrupulously spreading out-

Gold bar!

A whole box of gold bars!!

The other three boxes are also gold bars!!

"I think wizards probably don't accept pounds and cheques, and they shouldn't be able to swipe cards (1991 A.D. when the world of Harry Potter began, scan the code or something...... So prepare a little bit of the world's common currency......" Lin Xiaoan's smile was sincere and innocent.

……

Professor Snape had apparently never been so flaunted to his face, and was momentarily speechless: "......."

Over there, Dad Lin began to praise Lin Xiaoan: "Well done!" Baba actually forgot what to do if the human money (wizards: "......") is not collected over there! It's still Xiao An's brain, and he deserves to be my Sir Lin's son! ”

Yes, Lin Xiaoan's father, surnamed Lin, is named Sizzle, and what is even more coincidental is that he was really awarded the title of Sir and is worthy of his name.

……

Professor Snape came to his senses and said word for word, "Gringotts in Diagon Alley, the Wizarding Bank, can be exchanged for Muggles—that is, ordinary people who can't do magic—currency. ”

Lin Xiaoan blinked his eyes and pretended to be an ignorant child: "However, for a large number of cash transactions, the bank has to deduct a lot of handling fees~ Gold is a specialty of our own land, how much or how much we want, and it is the most affordable to spend it-ah!" Professor Snape! Isn't the wizarding world the gold standard?! ”

Professor Snape (really!) Gritting his teeth, he said, "No, the wizarding world is also on the gold standard!" ”

"Thick - then I'm relieved!" Lin Xiaoan breathed a sigh of relief, and deliberately patted his chest with his little hand, indicating that a false alarm scared him.

Mother Lin was so moved that she began to wipe her tears: "Oh~ My child's paper~ How can you be so smart and so wise~ And so powerful~ It's just both civil and military~ Ma Ma is really proud~"

……

Professor Snape bluntly said, "Because Muggles can't use Floo powder, now, we're going to take the subway to ......"

"What? Subway?! Mother Lin exclaimed.

Mr. Butler stood up at the right time, so calm that he didn't speak: "The car is ready." ”

Professor Snape...... Professor Snape finally couldn't help but draw his wand!

…… Then he applied the [Shrink] and [Levitation] charms to the four suitcases, and whispered, "Go!" ”
