A cruise ship wrecked, and nineteen survivors were trapped on a dangerous barren island. Lin Feng was voted and driven out by the crowd due to safety concerns, having to step into the jungle alone, unexpectedly awakening the barren island survival system. He learned wilderness survival skills, hunting, salt making, and pottery crafting, slowly building a solid survival stronghold. The remaining survivors retreated to the rock wall recess, food gradually depleted, camp conflicts occurred frequently, and resource allocation disputes continued. When they saw the cooking smoke rising from Lin Feng's camp, human hearts began to waver. In the desperate situation, survival resources and human morality violently tug-of-wared, opening a grand drama of barren island survival full of choices and game theory.
