On the night of the shipwreck, Lin Chen is kicked into the sea by his boss, Zheng Han, while his younger sister is dragged away. All he has left is a red hair tie. He washes ashore on a deserted island and binds himself to a Wilderness Creation and Cooking System, which allows him to turn salt, spices, and seeds into the resources he needs to survive. But the island's true danger is the gray fog. The lack of food is far from the deadliest threat. Contamination factors gradually erode people's minds, eventually driving ordinary people insane. Across the entire archipelago, Lin Chen is the only exception: hot meals prepared according to the system's standard procedures can suppress the effects for half an hour, while medicinal cuisine can hold them off for a whole day. Salt thus becomes hard currency. Black Wolf seizes what he wants with a blade, while Lin Chen buys what he needs with salt. His missing sister is somewhere to the east. And so is the Fog Core.
