I Accidentally Became The Ieader Of A Primitive Tribe

I am a historian who accidentally became the chief of a primitive tribe! Historical knowledge and chieftain system all rolled into one. Drilling wood to make fire, cutting ice to fish, taming livestock, and hunting with bows will take you to experience the pastoral scenery of primitive tribes! There are also fortifications, battles for other tribal territories, and the same primitive life. My appearance opens up a different path to rise!
