Start Death Row: Traveling Through Ancient Times to Build Infrastructure

Li Hao, a 35-year-old civil engineering contractor and history enthusiast. He is shrewd but generous, able to endure hardships, and understands the ways of the world. In a construction site accident, he accidentally traveled through the "Yan Dynasty". There is no omniscient and omnipotent system, only a "smartphone" that follows the protagonist's soul and contains a modern knowledge base (the battery is only 10%, and cannot be charged, so use less). The protagonist does not seek to become king and hegemony, he only has one initial goal - to survive. Use modern knowledge to create your own, stable "base" in a world that is about to collapse. His weapons are not Fang Tian Hua Ji and Qing Long Yan Yue Dao, but engineering, management, agricultural technology and a little bit of vision beyond the times.
