I and Brother Bald Dominate the Sea

A tsunami floods the land, making fresh water the most precious resource in this maritime apocalypse. Chen Mo, whose water purifier was stolen by Zhao Wu and who was kicked into the sea, accidentally activates a construction system. Starting from a broken raft, he saves Lu Xiaohao and reunites with his lost brother, Ah Qiang. By trading purified water for materials and gathering survivors through established rules, they fight the狂鲨 faction through salvage operations, construction, and naval battles. Ultimately, they upgrade their refuge into the mobile city-state 'Chen Shen', capable of housing 1,200 people, and set sail towards the unknown Arctic.
