A monstrous flood engulfs the world. Chen Fan awakens in the ruins and survives with a shipbuilding upgrade system and a broken raft. He hunts mutated beasts and gathers materials to upgrade his warship, befriends a water-controlling willow maiden and a hacker to build an exchange platform for 100,000 survivors, stands against underground forces and the disaster of the Water God, and builds an indestructible doomsday ark.
