Traveling to Ancient Times to Build Infrastructure: Leader, Don't Mess Around!

In an accident, Bai Xiaoning traveled to an ancient tribe. The tribesmen saw that she was thin and pale, and that she was not someone who could contribute to productivity. Why not kill her and eat her meat? ! However, the clan leader said that it would be better to keep the baby alive. These crazy primitive people! ! Wait, I'm still useful... So... Bai Xiaoning relies on medical skills to reduce tribal mortality. Cook cooked food and refine fine salt to improve the taste of food, so that eating is no longer just for survival. Make tools to increase productivity. Craft weapons to deal with ferocious beasts. But why is the tribal leader always waiting for an opportunity behind him? Dog man, don't delay my infrastructure construction!
