After a maritime accident, several ordinary city dwellers find themselves stranded on a deserted island. The male lead unexpectedly unlocks a daily sign-in ability that provides survival supplies and enhances his physical strength. At first, disagreements drive the survivors apart, but as reality sets in, they put their differences aside and work together to face the island's many challenges. They learn to gather resources, build shelters, and practice hunting and defense. They also gradually communicate and coexist with the island's native inhabitants, resolving misunderstandings and helping one another. United in purpose, they work together to fell trees and gather materials, spending several months building a large wooden ship with their own hands. After enduring countless hardships, everyone finally sails away from the island, returns to modern urban life, and begins a new chapter of ordinary living.
