Two-Way Transmigration: Building Infrastructure in the Neolithic Age

He transmigrates to the Neolithic Age and starts out surrounded by a group of primitive people staring at him.

The old woman who leads them asks, “Have you come to marry, or to declare war?”

Chen Mu shrugs and says, “I've come to build things.”

From that day on, the Rock Tribe has fish stewed in iron pots, shrimp caught in fishing nets, and all the white sugar and fine salt they could want...

He becomes a construction maniac in the primitive world, then returns to Blue Star to sell prehistoric antiques.

The only problem is that all the women in the tribe want to have his children.
