[Prehistoric] I Relied on My Spiritual Power to Build Infrastructure and Became a Saint.

Yin Xin finally built the Shang Dynasty, but he was defeated again! Oh, primitive, Tongtian, Hongjun, this time it is a real prehistoric world. Everyone was busy becoming saints, but Yin Xin felt that this was too far away, so he might as well engage in scientific and technological construction. The prehistoric world is great, with sufficient spiritual energy, which can be used as a pure natural and pollution-free power source. It just so happens that the human race is booming, spiritual steel-making, spiritual planes, spiritual trains, even a hole in the sky can be made into a spiritual dam to generate electricity! This is a paradise for infrastructure geeks! As a result, construction continued, and Yin Xin became a saint. Yin Xin: Don't ask me, I don't know either [looks confused. Jpg]. Mission: Powerful technology
