On a stormy night under a severe-rain warning, Lin Wan and her best friend Su Yao receive a mysterious warning that they will transmigrate. When a jade pendant turns into an entrance to a pocket dimension, the two spend every last coin they have stocking it to the brim with supplies, then plunge into a disaster-stricken year of endless wasteland.
Drought demons run rampant, corpses litter the roads, official grain is poisoned, and refugees struggle like ants on the brink of death. They avoid the surging crowds and find a hidden, uninhabited island.
The spring water in their pocket dimension irrigates the island's barren land, while modern knowledge lights their way out of despair. This time, with supplies filling their stores and their cleverness to rely on, they will build a secure home on the island for themselves and the few villagers who follow them. They won't get involved in the power struggles beyond their shores; instead, they'll live happily for the rest of their lives in the secluded paradise they have worked so hard to create.
