Yunhuang, a doctor of agriculture, once traveled through time and became the daughter of a criminal who was exiled to the north. Faced with dire wolves, freezing cold conditions, and murderous threats, she silently bound a doomsday scientific research base.
When everyone is struggling to survive, she has begun——
Solving famine with potatoes and corn,
Fight the barbarians with crossbows and city defenses,
Establish order with contribution points and EFA.
She transformed the wild north into a technological power that the empire coveted. When the old enemy and the current prince led their troops to the city, what they saw was not a dilapidated camp, but towering city walls, roaring industries, and a steel division that believed in science.
Yunhuang stood on the wall, behind her were the troops ready to go and countless people who trusted her.
"Everyone," her voice was calm but resounded throughout the world, "should you kneel down and surrender, or should you try the iron fist of technology?"
This is a hard-core history of infrastructure construction, looking at how modern science ignited the flames of civilization in a wild world.
