Hogwarts: This Wizard Wants to Progress Too Much

Transported into the Harry Potter world, on the day he received his Hogwarts letter, Ethan awakened a system of achievements. As long as he accomplished corresponding events, he would receive rewards.

With three million Galleons, he achieved the accomplishment, "Wealthy Beyond Compare."

Gaining the bloodline of a magical creature, he achieved the accomplishment, "I'm No Longer Human."

Using the Killing Curse to kill one hundred wizards, he achieved the accomplishment, "Lover of Big Melons."

...

On graduation day, as Ethan seamlessly took up the position of Minister for Magic, a reporter from the Daily Prophet asked him,

"Mr. Adrian, as the youngest and most outstanding Minister for Magic in history, I heard that you became famous throughout Hogwarts in your first year, obtained the Order of Merlin, First Class in your second year, and directly defeated a professor in your third year... What is the reason for your remarkable achievements?"

Ethan Adrian spread his hands: "I really wanted to make progress!"
