Lin Huaiyuan, a modern genetic researcher studying the clans who migrated south during the Western Jin dynasty, is struck by a bolt of lightning. When he opens his eyes, he has become a three-year-old scion of a fallen state amid the Upheaval of Yongjia. No golden finger.
Luoyang falls, the northern tribes massacre the city, and his family flees south in a desperate migration. The road is littered with corpses and rife with conspiracies, while his own uncle keeps scheming to harm the whole family. Others can run for their lives, but as a helpless toddler, he can only swallow all the modern knowledge of farming, herbal medicine, and infrastructure that fills his head.
From clearing wild hills to plant rice, to using herbs to save a Shanyue tribe; from being bullied and shunned by Jiangnan's great clans, to improving irrigation, soil, and farmland with agricultural techniques and infrastructure projects, he leads refugees in reclaiming land and joins forces with the Shanyue to build a life together. Along the way, he delivers face-slapping after face-slapping to his enemies and secures his family's livelihood.
While others struggle to survive in troubled times, he farms with cutting-edge know-how, turning barren slopes into vast fields in the Eastern Jin. From a young refugee, he grows into a land-reclamation magnate no one in Jiangnan dares to provoke.
The times are harsh, but farming and building infrastructure can really win the day.
