Invisibility and Teleportation in Another World: I'm Overpowered!

(An overwhelmingly powerful golden finger. If that's not your thing, don't read. There's some logic, but don't scrutinize it too closely.)

[Everyone's favorite + alternate world + feel-good power fantasy + secret identities + redemption]

If you can't beat them, join them.

But when she opened her eyes again, she had become a little beggar in another world, with a golden finger... a 10,000-mu watermelon farm and three mystery boxes.

Now watch as she grows from a little beggar into an imperial merchant.

P.S. The heroine has more secret identities than you could ever count.
