Transmigrate to a Chaotic Era and Build Infrastructure

Huan Luo transmigrates into a time of turmoil. His father is a powerful general who commands a vast army and holds the court in his palm; his stepmother is the noble-born eldest princess of the reigning dynasty. Yet he is a concubine-born son whom the history books say died young. Most importantly, he has a younger brother who intends to usurp the throne and declare himself emperor, only to bring ruin upon their entire clan when his plot fails. A promising start, if only he hadn't begun on hell mode. His general father thinks of nothing but marching north, reclaiming lost territory, and returning to the old capital. Huan Luo is obsessed with farming and has no interest in politics. The Xiongnu, Xianbei, Jie, Di, and Qiang tribes are fighting fiercely in the north, while the Central Plains have descended into chaos. Huan Luo is obsessed with business and has no interest in conquest. The small court that has retreated to the south of the Yangtze is beset by internal and external crises and is falling apart. Huan Luo is obsessed with infrastructure and carving out his own domain. Then, before he knows it, Huan Luo unifies the realm and successfully replaces the dynasty. Huan Luo: I only want to farm, do business, and build infrastructure, but you all insist on making me emperor!  ~*~*~*~*~*~[Reader's Guide]~*~*~*~*~ 1.
