He wants to shrink you again, hopping through black holes until you get to Earth The magical size bracelet chapter 35 by SatireMarker

"What if I shrink you again?" Josh asked slowly. "Maybe you'll just come back here."

You scoffed. "Josh, you know how big space is? I have no idea how many black holes I went through. I could end up anywhere."

"Better to do it than not do it. Isn't it."

You supposed you couldn't argue with that. "Alright then."

"Good. Doing it now."

And you felt yourself shrinking again. It was a much more rapid loss of size this time, as you returned to the smallest height you'd reached earlier almost instantly. It was dizzying. Once again your were surrounded on all sides by the blue quantum foam, and you felt yourself pulled into one black hole after another. After five minutes of this, Leon returned you to three inches tall.

Where are you now?
