The First Civilization

When Aren opened his eyes, he remembered only one thing—his name. With no memories of his past and no idea how he arrived in a world untouched by civilization, he finds himself living among a small primitive tribe struggling to survive against hunger, wild beasts, and endless conflict. As fragments of his memories slowly return, a mysterious Civilization System awakens within him. Unlike ordinary systems, it grants no overwhelming power. Instead, it restores pieces of the knowledge he once possessed, allowing him to guide his people one step at a time. From building the first homes and cultivating the land to forging laws, armies, and nations, Aren begins a journey that will change the course of history. But the deeper he uncovers his forgotten past, the more he realizes that this world holds secrets far older than civilization itself. Will he simply survive... Or will he become the man who creates the first civilization? — Description from novelcodex.org
