I Rule the Primitive Tribe, and My People Thrive

[Primitive Era, Infrastructure Building, Tribes, Strong Female Lead, No Romance, System, Imaginative Premise] A modern female doctor of traditional Chinese medicine unexpectedly transmigrates into a primitive tribe. Faced with a desperate situation, she uses her knowledge to solve one problem after another, inventing and creating things to make sure her people have enough to eat and warm clothes to wear. With a System at her side, she leads her people to rise step by step and build a civilization. In the end, she becomes the goddess of this continent... (The heroine has a System and men admire her, but they are all unrequited. She shines on her own, and there is virtually no romance.)
