Blue Star Era: My Tribe Can Be Upgraded

The world was shattered, and Blue Star fell into the wilderness. Others start with a knife, but I start with a "Five-Year College Entrance Examination and Three-Year Simulation"... Oh no, it's the entire history of human civilization! Civil engineer Chen Mo discovered that his golden finger was actually the "Spark of Civilization" - capable of analyzing all things and reproducing technology. Rune waterwheel? Magic blast furnace? Others are still drinking blood, while my tribe has lit up the industrial revolution. When the undead and natural disasters came to the city, what rose behind me was the Great Steel Wall and the Floating Fortress. This is not one person's path to invincibility, but an immortal epic that leads the entire race to the top of the world.
