I Founded Human Civilization in a Primitive World

This book is also titled I Unified Humanity in the Primordial World.

[Not a pure farming novel. The protagonist's golden finger is a book stored in his mind. From a small tribe to founding the Imperial Court of Humanity, he writes the story of human civilization.]

Yang Chen, a young man from Earth, accidentally transmigrates into a small tribe in the primordial wilderness. He becomes a divine envoy thanks to a lighter, and the only thing he can rely on is a book in his mind recording the civilizations of his previous life. Watch as this young man leads his tribe to stir up the wilderness, stands alongside the great tribes of Xuanyuan and Chiyou in a three-way contest, then defeats them in battle and writes the history of human civilization.

The boundless wilderness stretches beyond the horizon; a young man's ambition reaches for the highest heavens. The changing tides of time carry dreams far away; moonlight falls on a lonely shadow, and tears stream down.
