Lu Xiaozhu, an outstanding graduate student of the National Academy of Agricultural Sciences, traveled back in time to the ancient tribal era due to overwork, and possessed the body of a year-old girl, Lu, and later changed her name to Lu Xiaozhu. At this time, the tribe had just experienced a tragic conflict, and there were only more than fifty old, weak, sick and disabled people left. The tribesmen were full of doubts about her as a young leader. On the way to find a new place to live, Lu Xiaozhu rescued Awu and his grandparents, and also obtained the mysterious system [Spiritual Book].
In the process of leading the tribe to build their home, Lu Xiaozhu faced many great prospects. Other tribes were jealous of its development and continued to plunder. The harsh natural environment and primitive social form required her to lead her tribe to establish a strong civilization in a short period of time. Differences in development concepts led to misunderstandings between her and some tribesmen, and she was questioned as having impure motives. Every time they overcome difficulties, they are accompanied by casualties among their clan members.
But Lu Xiaozhu did not back down. She used the [Spirit Book] to exchange skills and led her tribe to build houses, build roads, farm land, open various places, and implement new systems. Awu and his eldest brother Shan became the pillars of force, and their families each had their own strengths to help the tribe develop. Awu also fell in love with Lu Xiaozhu while getting along, and became a general, opening up territory for her. In the end, with the efforts of everyone, the tribe developed and grew, blooming with the light of ancient civilization.
