Chaoyang Empire 1973

An ordinary modern person with memories of modern knowledge is reborn as a teenager in 1973. He possesses a two-way time travel ability (core cheat: shuttling between modern and 1973). He doesn't rely on brute force but uses supplies, technology, information, and business thinking to rise from personal survival to gathering followers, establishing a faction, and building a regime. The writing style is realistic, with elements of infrastructure development, farming, power struggles, and hegemony. It incorporates traditional culture (the Qian hexagram) and differs from ordinary time-travel power fantasies.
