The Strongest Wizard in the Collecting World! [Mainly Harry Potter Crossover]

[Written for Afdian, but I ran out of power, so I abandoned it. Thanks for understanding.]

Dora has forgotten almost everything about the HP world. After transmigrating into it, she has one clear goal:

Transmigrate back!

And the magic circle that can send her back really does exist.

But the things needed to inscribe the magic circle...

The Elder Wand? The blood of a loved one?

Dora: ... I-I'll work hard to become the greatest collector in Eurasia!

Male lead undecided. Feel free to pick your favorite.

Theme: Perseverance brings results in the end
