Jiang Xiaohe was locked up in a cold storage by his biological mother and Fatty Po Lan, and was reborn before the apocalypse broke out. She used online loans to drain her family's credit, hoarded supplies and renovated cold storage, took revenge on Fat Po Lan in the extreme heat, and witnessed her parents and younger brothers killing each other in the extreme cold. She used high-voltage power grids, liquid nitrogen traps, and drones to harvest greedy people, and took in her benefactor Aunt Chen and the powerful black dog. When the extreme cold ended and the Great Blight came, she burned the old world, took her belongings and sailed into the mountains, becoming the sole ruler of the new world.
