The global continent suddenly shattered, and humanity was collectively teleported to the boundless ocean. At the start, everyone has only a small island of a few square meters and a worn-out fishing net. Food, fresh water, and resources must all be obtained by oneself, while the seawater continuously devours the islands, and a moment of carelessness will lead to burial at the bottom of the sea. In a desperate situation, Lin Mo awakens the Daily Roulette Draw System. While others are still struggling desperately for a mouthful of fresh water, he pulls an SS-grade fully automatic fishing machine. Starting from fishing, trading, and expanding the island, he step by step builds his own marine base. As tidal disasters, resource competition, sea beast lords, mysterious ruins, and various factions appear one after another, Lin Mo's island continuously upgrades and expands.
