Conquer the Three Kingdoms Through Infrastructure

I transmigrated into the Three Kingdoms era and was reborn as Emperor Xian of Han, Liu Xie, who had just escaped from Chang'an. Cao Cao is closing in from the front, while the remnants of Dong Zhuo's forces are lurking behind me with sinister ambitions. What should I do? Activate the System, reclaim wasteland and farm it, fell trees and mine ore, build cities and train troops... Recruit famous generals from the Three Kingdoms! Strike north against the Xiongnu on the grasslands, resist the warlords in the Central Plains, hold Youzhou and keep the world in my sights! Watch as I bring this chaotic era to an end, conquer the Three Kingdoms, and found a new dynasty for China!
