Bao Ruanruan, an overworked corporate employee, is transported to a post-apocalyptic world where people are exiled across the sea. She awakens an island survival system, but starts with nothing more than a miniature island the size of her palm. Along the way, she befriends the sea spirit Aowu, swordsman Su Lin, and stranded senior general Gu Chen. Together, they fight against sea beasts, pirates, and the Inspectorate's forces while sheltering displaced exiles. Starting from nothing, they build New Hope City, an equal and prosperous city-state, challenge the rigid hierarchy of Shenfeng Harbor, and uncover the secrets of genetic experiments and psychic weapons from the old world.
