In his previous life, entrepreneur Chen Jingming transmigrates into the body of a five-year-old boy from a farming family. Faced with a biased grandmother, greedy relatives, and a family with barely anything to their name, he uses his modern knowledge to identify medicinal herbs, raise tussah silkworms, and grow watermelons, leading his family out of poverty and into prosperity. He takes on troublesome relatives, opens shops, befriends a noble heir, and presents rare treasures, carefully advancing step by step from a mountain village to the imperial court. Eventually, thanks to inventions such as the curved-beam plow and the abacus, he is granted the noble title of Earl of Xing'an and receives an imperial golden plaque, completely transforming his family's destiny and achieving an extraordinary rise in social status.
