Ruan Tian, a young farmer, accidentally dug up the legendary "Nugget Gold" while working in the fields during a drought year. Faced with this huge wealth that changed his destiny, he chose to handle it carefully, gradually improving his life while not forgetting the roots. After marrying his virtuous wife Li Yuer, Ruan Tian used his wisdom to deal with the forces coveting gold from all sides, including the repeated retaliation from the gold minister's remaining party.
With the help of the censor and others, Ruan Tian repeatedly resolved crises and used his wealth to build schools, dig wells and roads, and promote agricultural technology. He trained his eldest son Wenxuan to become an upright official, his second son Wenhao to become an agricultural expert, and his daughter Wenhui to show her business talent. Despite many hardships such as plagues, natural disasters, and official strife, Ruan Tian always adhered to the belief that "life on the ground is more precious than gold underground" and eventually donated most of his family property to a fund to aid education and agriculture, making the Ruan family the most respected "righteous family" in the local area.
