Transmigrated to Type-Moon, but 50,000 Years in the Past

A college student from the modern world unexpectedly transmigrates to the Nasuverse fifty thousand years in the past. In this primitive age, when the future of human civilization has been cut short and the Counter Force can no longer grow, he will use his knowledge of the future to lead the Homo sapiens out of Africa and guide them step by step toward the stars, opening a new chapter in humanity's migration and exploration. An adventure that will shape history awaits you!

I'm a new author. Glad we met.
