Li Qiye transmigrates into an apocalyptic alien ocean, stranded on a rusty iron raft platform measuring just four square meters. Using a survival system to disguise the alien world as a holographic game, he summons players from Blue Star to descend into this world. Fishing fanatics catch priceless extraterrestrial fish, engineering experts expand the base, and the military trades weapons for imperial technology. Together, they rescue Ivana, salvage underwater ruins, activate cross-region teleporters, and exchange fresh water and white liquor for vast quantities of building materials, transforming a dilapidated raft platform into an offshore fortress. Just as the base is undergoing a comprehensive upgrade, an alien storm suddenly bears down on them.
