I Was Trapped in Ancient Times at the Beginning, so I Just Started to Rub Civilization

Su Mo, a civil engineer who graduated from Dingduang University, was summoned by a big pink truck and traveled to a different world as expected, becoming the leader of a wild tribe. There is a sacrifice at the beginning, and there is a 24-hour beast wave. While others knelt down and worshiped the gods for survival, he took out the blueprint with his backhand: "Flint + ironwood = blast furnace, city wall + runes = energy barrier." While other tribes were still cultivating slash-and-burn farming, he had raised the banner of the Mechanicus. When the god lowered his gaze, his steel fleet filled the void. This is a story about an era in the cemetery of civilization.
