Global Shipwreck: My Shelter Ship Can Upgrade Without Limit

Luffy was caught by the System and sent to a parallel world once again during a storm.

In this parallel world, rising carbon dioxide emissions and humanity's massive destruction of the environment caused the polar ice caps to melt and sea levels to rise, leaving less than thirty percent of the planet's surface as land!

Almost everything people ate and drank came from the sea, and they depended on ships to survive.

The System brought Luffy to a raft on the ocean in this parallel world. He had to survive the natural disasters that were on their way while continuously upgrading his shelter.

No crops? I'll grow my own on the boat!

No water? I've got so much bottled water, I'll never finish it all!

In the apocalypse, he turns his survival ship into a paradise that everyone envies!
