A Magic Awakened Player Transmigrates into the Original Harry Potter Story

You are a launch-day player of NetEase's new IP mobile game, Harry Potter: Magic Awakened, when you suddenly transmigrate into the original Harry Potter books for an extraordinary adventure.

Including, but not limited to, the following:

Avada Kedavra

Using Bella's Echo to duel Death Eaters

Saving people from tragic fates

There's a slight hint of a System? It's not the kind that gives you missions and talks to you. If I had to describe it, I guess it's the will of NetEase (solemnly).

Some people say the female lead has big-sister vibes, so let's go with that. She's an adult who treats Harry like a child.

Warnings:

The protagonist is over 20, older than Harry and his classmates, but younger than Harry's parents' generation.

The protagonist has no house or name. The whole story is written in the second person for easier self-insertion.

The protagonist is an ordinary Chinese person, not a British pure-blood or part of an ancient family.

The protagonist is very good at fighting.

The original story's events are treated seriously and aren't made overly dramatic.

Theme: A lighthearted, witty power fantasy with a realistic touch.
