In the wild wilderness of the Neolithic Age, veteran Zhao Ye was reborn with the "Foundation System of Ancient Civilization" and became a boy of the Zhao tribe on the verge of extinction; modern scholar Zhao Yan accidentally turned into the "Ten Thousand Miles of Rivers and Mountains Map" and relied on the "Mountain and River Deduction System" to know the world and yin and yang, and became a helpless scroll spirit. A bond in a desperate situation of life and death made the two become symbiotic partners - Zhao Yan used the projection of mountains and rivers to point to resources and warn of disasters, while Zhao Ye relied on the system to unlock stone tools, fire farming, and city-building skills, and led the remaining troops into the wilderness surrounded by mammoths to fight against flash floods, fight against different tribes, and survive severe droughts. From a temporary camp to the Zhao city that is beginning to take shape, from scattered survival to united tribes to form an alliance, the two protagonists use the power of dual systems to forcibly carve out a path to lay the foundation for civilization in the wild world, making the surname "Zhao" the earliest mark of civilization on the ancient land.
