Lin Ran transmigrates into the beast world and becomes a useless female of the Black Wolf Tribe, despised by everyone. With the cold season approaching, her fiancé publicly abandons her in the wilderness to die. But relying on her modern knowledge of agriculture, forestry, and survival, she starts fires with her bare hands, builds shelters, constructs heated kang beds, finds staple foods, refines salt, and makes pottery. She forms an alliance with Yin Xiao, a seriously injured warrior, and builds a home from scratch amid the icy wasteland. The once-abandoned, worthless female will ultimately ignite the flame of civilization in the beast world.
