I Awakened Copying On The Sky Island!

I, along with 1.4 billion people, was thrown into a world of sky islands. Everyone started with the same: a fishing rod, a piece of bread, a bottle of water, and a dilapidated instruction manual. I am number 9527, and I awakened a hidden ability: once a day, I can copy any item.

With my fishing rod, I catch clouds under the island—and one day, not supplies, but a living person gets caught on the hook. He calls me master and says he is Lu Bu. But monsters, air pirates, and island 414, which knows where I am, are already appearing on the island.

How long will my island last when the real storm comes?
