After the sinking of the Old World, the deserted sea became the last place for human survival. Retired marine researcher Lu Chenzhou guards a dilapidated fishing house and barely survives by fishing, repairing and recording tides.
On the eve of a storm, he caught an abnormal fish that should not appear in the shallow sea and saved his first companion. From now on, fish harvests are no longer just food, but may also be materials, energy, clues, and even monsters that pollute the base.
Lu Chenzhou led structural engineers, ship maintenance personnel, doctors and other survivors to build a temporary shelter into a floating city on the deserted sea step by step, starting from old boats, floating platforms, fish rafts and workshops. The truth about the catastrophe concealed by the old organization, the sea-fit people who choose to integrate into the ocean, and the expanding alien ecology in the deep sea are also approaching them.
In this landless apocalypse, should humans control the ocean, adapt to it, or make a new covenant with the ocean?
