Traveling in Both Directions: I Was Engaged in Infrastructure Construction in the Neolithic Age

Traveling through the Neolithic Age, you are surrounded by a group of primitive people at the beginning. The old lady leader asked him: "Are you here to get married, or are you here to declare war?" Chen Mu spread his hands and said, "I'm here to build infrastructure." From then on, the Panshi Department had enough fish stews in iron pots, fishing nets to catch shrimps, and tubes of white saccharine and salt... He worked as an infrastructure madman in primitive times, and returned to Blue Star to work as a prehistoric antique dealer. The only problem is - all the girls in the tribe want to give him children.
