Everyone has an island, I can copy it infinitely!

Billions of people around the world traveled together!
Each person has an empty floating island and a fishing rod.
The only way to get supplies on the floating island is to use the fishing rod to fish in the clouds and get survival supplies.
But Jiang Tian unexpectedly obtained the [Copy System]!

"Copy the fishing rod!"

"Copy the supplies!"

"Copy..."
"..."
Just when everyone was still struggling to survive, Jiang Tian had already started a new way to play the sky island!
