Modern girl Hanzhi travels through time to an ancient clan tribe. Here, supplies are extremely scarce, and clan members barely manage to survive on grass roots and prey, lacking clothing and medicine, struggling to survive amidst hunger and cold. Relying on modern knowledge and the weaving skills she learned from her grandfather since childhood, Hanzhi starts from weaving the first grass clothing and the first pair of grass shoes, catches fish in the river, improves tools, searches for food seeds, and bit by bit solves the difficult problems of eating and keeping warm. Facing famine and a harsh environment, she leads a group of dependent orphan partners to improve their lives with wisdom and their hands, determined to make the clan members on the verge of desperation well-fed and warmly dressed, and to build a new home on the wild earth.
