Original Maternal Lineage: I Was Engaged in Infrastructure Construction in Ancient Times

[Primitive tribe + no CP + infrastructure + system + overhead + knowledge changes destiny] Sanya, who was too tired to work hard, came to the primitive tribe and became a primitive man. At the beginning, there is a small tribe of old, weak, sick and disabled people who do not have enough to eat or wear warm clothes, and their lives are in danger at any time. There is also a system that cannot be contacted at any time and anywhere. I am hungry and want to cry without tears. (Introduction is incompetent, move to the text)
