In the spring of the year Bingwu, Jiang Ning's son Lin Yan went to Beijing to take the exam. However, he encountered a local snake in Ma Sheng Lane and robbed him. When he came to help, he accidentally got involved in the old case of his father Lin Ruhai who was unjustly demoted twenty years ago due to a salt case. In order to seek his father's innocence, Lin Yan put aside his imperial examination achievements and started with an account book, half a copper coin, and a jade pendant to explore the truth. He successively dealt with Feng Shouyi, Zhao Shangshu and other traitors in the court, and even discovered the shocking conspiracy of King Zhu Zaihe to secretly open a silver mine and mint fake official silver. Together with his loyal servant A Qing, he linked up the righteous men in the world and the clear-minded people in the court. After going through many hardships and dangers such as house arrest, hunting down, and exploring the tiger's den, he finally found the ironclad proof of being a saint.
