The drama is adapted from the best-selling novel of the same name by Maoni. Continuing from the previous season, Fan Xian (played by Zhang Ruoyun) leads a delegation to return. On the way, the second prince threatens Fan Xian with the safety of Fei Jie, Fan Siche, and the orphans of the Teng family, forcing him to bow down and submit to him. This sparks the conflict between the two. The confusion of the Moon Tower that Fan Xian faced, as well as the subsequent crisis of the Spring Palace, were all traps carefully set by the Second Prince for Fan Xian. Fan Xian and Lin Wan'er got married as they wished, and immediately after, Fan Xian took over the internal treasury, only to find that it was heavily indebted. Fan Xian refused the help of the head shopkeeper of Qingyu Hall and decided to rely on his own efforts to solve the crisis in the internal treasury. Fan Xian arranged for various merchants in the city to gather in Cangshan and raised over 20 million silver coins by selling"treasury bonds", solving the problem of empty internal treasury. On the Hanging Temple, Emperor Qing was assassinated three times in a row, but Fan Xian intervened to save him, resulting in his martial arts being completely defeated. Crises abound, and the pressure increases sharply. Fan Xian has no choice but to enter Jiangnan with such a body, challenge the huge power and established game rules, in order to completely regain the inner treasury.
