Traveling through the world of Harry Potter, Merlin Hantle activates the world transformation system, and you can get rewards as long as you transform the wizarding world.

As a result, the old-fashioned magical world began to become a little different.

Ollivander: "Mr. Merlin's suggestion of metallizing the wand can really improve the magic conductivity!"

Nicolas Flamel: "Merlin is a better alchemist than me. Mithril is the cornerstone of changing the magic world!"

McGonagall: "Magic can actually be divided into six systems? What on earth has the Wizengamot been researching for so many years?"

Flitwick: "Although I don't understand the reason for the bayonet on the wand, close combat wizards are really ridiculously strong!"

Voldemort: "I, the second generation Dark Lord, will never be sealed from my magic. Break it for me!"

The Daily Prophet: "The wizarding world can't live without Merlin any more than it can live without Butterbeer!"

Dumbledore: "Who would believe that I have to pay school rent to Merlin Handel?"
