Blue Star collapses, and all of humanity is transported into an apocalyptic world of ocean survival. Qin Yuan, an overworked corporate drone, starts with nothing but a swan-shaped pedal boat and is mocked by his former boss and ex-girlfriend. After awakening the Daily Choice System, he discovers that ten refreshes guarantee all three top-tier supplies. Using seawater desalination and heavy weapons to monopolize resources, he continually upgrades his ship. Along the way, he teams up with Mu Qingxue, a top female player who possesses the Eye of True Sight. Together, they sweep aside mutated sea beasts and hostile player factions, gather the finest equipment to build an impregnable maritime fortress, slay the overlord of the seas, and ultimately crush an invasion from another world, becoming rulers of the entire ocean.
