Hogwarts: Who taught you to transform like this?

July, 1991.

There was drizzle in the sky above the foggy city, and the air was filled with dense fog.

On the eighth floor of Hogwarts, in the principal's office, Minerva McGonagall's eyelids twitched wildly as she assisted in signing the admission letter.

She put down her feather pen and looked over the mountain of letters at the silver-haired old man behind the table.

"Dumbledore, is there something going to happen to this year's freshmen? I suddenly have a bad feeling."

Dumbledore pushed his half-moon glasses.

"Minerva, eyelid twitching is normal. You are not Trelawney, and no one here will die. Don't be so nervous."

"I think you must be tired from working too much overtime recently. How about some cockroach piles to replenish sugar?"

Then he pushed a wide-mouthed jar over.

"Thank you, Dumbledore, forget it."

McGonagall pursed her lips and shook her head, rejecting this dessert that looked too weird.

"In fact, Albus, if possible, I suggest you change to some other desserts, at least they are more appetizing, such as..."

"Lemon Sherbet?"

Dumbledore took out a handful of candies with beautiful candy wrappers. "This kind of candy made by Muggles tastes really good."

"Oh, right!"

"Speaking of Muggles, Minerva, we have a little wizard from the Muggle world this year who needs your personal guidance."

Professor McGonagall was excited and clenched his quill.

"Professor, you mean Harry..."

"No, Minerva, I have arranged for Hagrid to pick up Harry, and I believe he will do a good job of this, just like he brought Harry back that year."

"Who else?"

"Merlin Hantel."

Dumbledore spoke slowly.

McGonagall showed a surprised expression.

"What's so special about this child?"

"In fact, you just wrote him an admission letter."

Dumbledore pointed to the table.

"His name suddenly appeared in the admission book two days ago."

"Usually, the admission book will sense the little wizard with magical fluctuations in advance and record it and tell me."

"But it is the first time that a name suddenly appears just before the start of school."

"And he happens to be from the same orphanage as Tom Riddle back then."

"Although we should not look at the problem with inherent thinking, it is better to confirm that he is different from Voldemort."

Hearing this, McGonagall's expression also became serious, and he understood what Dumbledore meant.

"Okay, professor, then I will go over and give him the admission letter in person now."

"Let me see, where is he now... huh?"

Dumbledore's expression was particularly strange.

"Minerva, you may have to go to the Leaky Cauldron to find this little wizard."

McGonagall: ? ? ?

"Albus, did you see it wrong? How could a little wizard from the Muggle world stay in the Leaky Cauldron?"

"Although I don't believe it, it's written in the admission book."

"Okay, I'll go over and take a look now."

McGonagall grabbed the admission letter he had just written and walked out of the office.

...

The Leaky Cauldron.

The boss Tom stood at the counter, wiping the cups while staring at the handsome little wizard in front of him with a secret vigilance.

"Merlin Hantel, what are you thinking about again?"

"I will never listen to you to transform anything today, and I will never let you drink butter beer again!"

Hearing Tom's words, Merlin Handel turned his eyes away from the butterbeer on the bar, with an incredible look on his face.

"Tom, I'm really hurt. You actually said that the methods I thought of for you were all crooked!"

"Think about it, if I hadn't suggested putting up a notice at the door of the bar that Muggle wizards could enter for consultation, how many wizards would you have missed?"

"But..."

"But what, and the bar's ordering mode, it's the magic age, you are still recording it verbally, it's really weak! Is the magic mark I recommended not useful?"

"Then..."

"Then what? Just tell me, has the bar's business become better since I came?"

"It has improved."

"That's good, you make so much money, what's wrong with treating me to a glass of butterbeer?"

Tom was silent.

Three days ago, when the little wizard named Merlin Handel came to the bar to find him and said that listening to his advice would make the Leaky Cauldron better, he didn't believe it at all.

But after renovating the bar according to his method, the income did increase a lot.

But he always felt that he seemed to be tricked.

Just as he was about to say something, Merlin interrupted him.

"In addition, I think you can try selling set meals, combining staple food, vegetables, steak, drinks, and desserts, and then selling them at a discount. Sales will definitely be better!"

"I'll try it tonight!"

Old Tom's eyes lit up, and he also thought this was a good idea, and hurriedly lowered his head to record it.

Merlin calmly took the butter beer that had just been poured from the bar and checked the system prompt in front of him.

[Detected that the host has transformed the Leaky Cauldron]

[Transformation range: small, rewards are being issued. ]

[Congratulations to the host for obtaining the item: one pound of mithril - an extraordinary metal refined by dwarven craftsmanship, with the characteristics of lightness, hardness, and strong affinity for magic. ]

"Why is it mithril?"

Merlin was a little surprised.

He traveled to the world of Harry Potter three days ago, and now his identity is a child adopted by the Wu Orphanage.

And the system that is indispensable for a traveler has also been bound.

World transformation system.

As long as you transform the magic world, you can get rewards. The greater the transformation, the better the reward.

Considering that he doesn't know magic yet and has no money.

The ability to transform the magic world was not enough, so he could only choose the simplest way to start. That was to transform the Leaky Cauldron. Because he was not familiar with the traffic routes. He changed several buses before he found this bar that connected the wizarding world and the Muggle world. It took a while for Old Tom to agree to his transformation. He transformed the Leaky Cauldron and got a lot of benefits three times. The first transformation gave him the Encyclopedia of the Magic World, which recorded common magic materials and magical creatures, as well as some local customs. The second transformation gave him the talent of magic affinity. The third time was now, and he gave him a pound of mithril. Although it was a good thing, Merlin was still very curious. There was no such metal in the original book, so why would the system give this reward? "Squeak." Before he could think about it, the door of the bar suddenly opened. A female wizard wearing a green cloak, a wizard hat on her head, and a dignified face walked in. She stood in front of the door, her eyes fixed on Merlin. After a long while, she slowly spoke. "Mr. Merlin, I'm Minerva McGonagall, the deputy headmaster of Hogwarts School of Witchcraft and Wizardry, and I'm here to give you your admission letter."

"But before that, I still have a question, why are you in the Leaky Cauldron?"
